detailed description

The method and system for monitoring the safety status of operators in offshore wind farms according to embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Embodiment one

Fig. 1 shows a method flow chart of an embodiment of the method for monitoring the safety status of offshore wind farm workers provided by the present invention, and the method steps can be executed in the offshore wind farm worker safety status monitoring system.

As shown in Figure 1, the monitoring methods for the safety status of offshore wind farm operators include:

S101. Monitor the status information of the safety equipment carried by the operator. When the safety equipment is used correctly by the operator, it triggers the use status detection device (such as a label card or a thimble set at the zipper closure. The following mainly uses the label card as an example. Explanation) sends status information.

Here, the status information is the information that represents the safety status of the operator. On the premise that the operator uses the safety equipment correctly, the status information is sent after being triggered by a tag card that integrates functions such as signal detection, signal processing, and sending and receiving signals. The safety equipment is Equipment to ensure personal safety for each operator before going to sea. The safety equipment can be, but not limited to, wearing equipment, hand-held equipment, etc. Correct use of safety equipment by operators can be understood as the correct use of safety equipment by the operator, for example, the safety equipment is safety clothing, and the operator puts on the safety clothing in the wind turbine and closes the zipper on it , which means that the operator has used the safety equipment correctly. On the premise that the above-mentioned safety equipment is correctly used by the operator, the zipper is pulled to make the power supply circuit of the tag card conductive, triggering the tag card to send the status information of the safety equipment.

S102. Generate a status result indicating whether the operator is safe according to the monitoring result of the status information.

Specifically, the monitoring results may include, but are not limited to, whether the aforementioned status information is monitored. If the status information is detected, it can be known from step S101 that sending out the status information indicates that the operator has used the safety equipment correctly, and it can be determined that the status of the operator is safe. , and then generate a status result indicating that the operator is safe. On the contrary, if the status information is not detected, indicating that the operator has not used the safety equipment correctly, then a status result indicating that the operator is not safe is generated.

The method for monitoring the safety status of operators in offshore wind farms according to the present invention monitors the status information of the safety equipment carried by the operators, and further uses the monitoring results of the status information as a basis to generate status results that identify whether the operators are safe. Remote monitoring of the safety status of operators, and subsequent measures to monitor unsafe conditions, minimize the safety risks of operators.

Embodiment two

Fig. 2 is a method flowchart of another embodiment of the method for monitoring the safety status of offshore wind farm operators provided by the present invention, which can be regarded as a specific implementation of the method embodiment shown in Fig. 1 . As shown in Figure 2, compared with the method steps of the embodiment shown in Figure 1, Figure 2 specifically shows how to trigger the tag card to send status information when the safety equipment in the wind turbine is correctly used by the operator; The monitoring results of the status information generate the method of identifying whether the operator is safe or not; how to trigger the label card to send the status information when the safety equipment outside the wind turbine is used correctly by the operator; if the operator is not inside the wind turbine and is not How will it be handled outside the wind turbine. As shown in Figure 2, the method for monitoring the safety status of offshore wind farm operators includes the following steps:

In step S101 , when the safety equipment is correctly used by the operator, the tag card is triggered to send status information. This embodiment shows two specific situations, which correspond to steps S201 and S202 respectively.

S201. In the wind turbine, when the safety equipment is correctly used by the operator, the use state detection device is triggered to receive the low-frequency activation signal sent by the low-frequency activator, and convert it into a wireless signal data containing state information and send it back to the antenna. Antenna sent out.

It should be noted that the use state detection device may include a label card. Specifically, a plurality of low-frequency activators and several antennas used in conjunction with the low-frequency activators can be arranged on a multi-layer platform inside the wind turbine. The low-frequency activator continuously emits low-frequency activation signals outward. When the operator uses the safety equipment correctly, the zipper is closed and connected to the power supply circuit of the tag card, thereby triggering the tag card to receive the low-frequency activation signal and convert it into The wireless signal data of the status information is sent back to the antenna, and finally the status information is sent by the antenna. Here, the tag card may be an electronic tag integrated with functions such as signal detection, sending and receiving, and processing.

Due to the limitation of signal transmission distance, when the operator is outside the wind turbine and uses safety equipment correctly, the triggered tag card cannot communicate with the low frequency activator and antenna. The following shows how the safety equipment triggers the tag card to send out status information when the safety equipment is used correctly outside the wind turbine.

S202. Outside the wind turbine, when the safety equipment is correctly used by the operator, the use status detection device is triggered to send a wireless signal containing the status information of the safety equipment to the mobile terminal, and then the mobile terminal forwards it.

Here, the use state detection device may further include: a thimble provided at the closing position of the electromagnetic zipper. Specifically, when the operator uses the safety equipment correctly, the electromagnetic zipper is closed and contacts the thimble, thereby triggering the use status detection device to send the status information of the safety equipment to the mobile terminal held by the operator, and finally the mobile terminal forwards the status information.

In a specific implementation, the use state detection device can also be integrated with a hardware module (such as a single-chip microcomputer) that realizes functions such as signal sending and receiving, and signal processing, such as a life jacket equipped with an electromagnetic zipper. The thimble outputs a high level to the single-chip signal processing module, and the single-chip signal processing module converts it into a wireless signal containing status information and sends it to the signal transceiver module, and then the signal transceiver module sends the status information.

On the basis of the above steps, in step S102, the process of generating status results identifying whether workers are safe or not according to the monitoring results of the status information also includes two specific situations, which correspond to steps S203 and S204 respectively.

It should be noted that the monitoring result may include: whether the status information is monitored, and when the status information is monitored, analyzing the identification of the antenna in the wireless signal.

S203, if the status information is detected, according to the antenna identification, determine the first position identification of the operator in the wind turbine; and generate a safe state result including the first position identification of the operator in the wind turbine; if not detected state information, an unsafe state result that the operator does not use the safety equipment correctly is generated.

Here, the first location identifier may be, but not limited to, preset numbers, symbols, etc. that indicate whether the operator is located in the wind turbine. For example, a marker of "1" indicates that the operator is The workers are not inside the wind turbine. Alternatively, the first location identifier may also be latitude and longitude coordinate data representing the location of the operator in the wind turbine, specifically, a table of correspondence between longitude and latitude and the wind turbine is preset, for example, longitude 117.03 and latitude 23.44 correspond to the wind turbine. In a specific implementation, the installation position of the antenna in the wind turbine is in one-to-one correspondence with the antenna identification. Therefore, when the antenna sends out status information, it indicates that the antenna has monitored the status information of the safety equipment, and the operator has used the safety equipment correctly. Produce results where workers are inside the wind turbine and workers are safe. If the status information is not monitored, indicating that the operator is not using the safety equipment correctly, an unsafe result is generated that the operator is not using the safety equipment correctly.

Based on the above-mentioned introduction of the mobile terminal function, here, the status information of the safety equipment forwarded by the mobile terminal may also include: the second location identifier determined by the mobile terminal using the built-in GPS positioning device, the identifier of the mobile terminal, and the identifier of the safety equipment.

In a specific implementation, the operator is also equipped with a mobile terminal and safety equipment when he goes to sea. Similar to step S203, the second location identifier can be, but not limited to, a preset symbol indicating whether the operator is located outside the wind turbine. Numbers, symbols, etc. (or directly use the equipment identification of the mobile terminal as the location identification, of course, the premise is to ensure that the operators strictly abide by the operating specifications that only use the mobile terminal outside the wind turbine). Alternatively, the second location identifier may also be latitude and longitude coordinate data indicating that the operator is located outside the wind turbine. For example, the built-in GPS positioning device in the mobile terminal can obtain the latitude and longitude coordinate data, which will not be repeated here. In addition, the identification of the mobile terminal is used to identify the mobile terminal equipped by each operator, and similarly, the identification of the safety equipment is used to identify the safety equipment equipped by each operator.

S204, if the state information forwarded by the mobile terminal is detected, generate a safe state result that the operator is outside the wind power unit including the second location identifier; if the state information forwarded by the mobile terminal is not detected, generate Unsafe state results outside the unit.

Specifically, only when the operator uses the safety equipment correctly will the tag card be triggered to send status information to the mobile terminal. Therefore, monitoring the status information forwarded by the mobile terminal indicates that the safety equipment is being used correctly by the operator, thus generating Exceptions and the safety of workers. On the contrary, if the status information is not monitored, it indicates that the operator does not use the safety equipment correctly, and an unsafe result is generated that the operator does not use the safety equipment correctly.

In this embodiment, there is also the situation that neither the status information sent by the antenna nor the status information forwarded by the mobile terminal is detected. The method for monitoring the safety status of the offshore wind farm operators may also include: If the status information of the machine is not available, it will give an alarm prompt to remind the operators to operate in accordance with the safety regulations, thereby reducing the occurrence of accidents and minimizing the safety risks of the operators.

Here, the manner of prompting an alarm may be through, but not limited to, a flashing indicator light, a prompt sound, a preset prompt icon, and the like. For example, when the operator is outside the wind turbine, it is assumed that the operator is wearing the safety clothing that is equipped for him, and according to the safety operation regulations, the use of the safety clothing is inside the wind turbine. Obviously, the operator is in The location does not match the environment where the safety equipment is used, and an alarm will be prompted at this time.

Since the environment inside the wind turbine is different from that outside the wind turbine, in order to better protect the safety of the workers, safety equipment suitable for different environments inside/outside the wind turbine is provided. Preferably, the safety equipment may include: suitable for inside/outside the wind turbine other wearable devices.

Correspondingly, in steps S201 and S202 of this embodiment, the state that the safety equipment is correctly used by the operator may include: the operator wears a wearable device suitable for the wind turbine in the wind turbine, and the wearable device can trigger the corresponding tag The card receives the low-frequency activation signal sent by the low-frequency activator; or the operator wears a wearable device suitable for outside the wind turbine, and the wearable device can trigger the corresponding tag card to send the status information of the safety equipment to the mobile terminal.

In a specific implementation, there are two situations in which the above-mentioned safety equipment is used correctly by operators. One is wearing wearable devices suitable for the wind turbine in the wind turbine. For example, the operator wears safety clothing in the wind turbine. When the operator puts on the safety clothing and pulls the zipper on the safety clothing, the tag card will be triggered as the zipper on the safety clothing is pulled, and receives the low-frequency activation signal from the low-frequency activator, thereby triggering the tag card to send out a safety alarm. The status information of the safety clothing is monitored, indicating that the operator has made the above-mentioned series of actions that meet the operating specifications, that is, the safety clothing is used correctly by the operator.

The second is that the operator wears wearable devices suitable for outside the wind turbine. For example, the operator wears a life jacket outside the wind turbine. When the operator puts on the life jacket and pulls the zipper on the life jacket, the label card will It is triggered when the zipper on the lifejacket is closed, and sends status information of the lifejacket to the mobile terminal. The status information of the lifejacket is monitored, indicating that the operator has made the above-mentioned series of actions that meet the operating specifications, that is, the lifejacket is used correctly by the operator.

In addition to the above two situations where the safety equipment is correctly used by the operator, there are also situations where the safety equipment is not used correctly by the operator. For example, the operator is in the wind turbine, but instead wears a wearable device suitable for outside the wind turbine. Specifically, when the status information is monitored, the aforementioned status information may also include the identification of the mobile terminal. Therefore, according to the identification of the mobile terminal, it can be known that the operator puts on the safety equipment and pulls the zipper, and the trigger tag card sends out the status information. , and the state information is forwarded by the mobile terminal, so that it can be judged that the safety equipment worn by the operator is a wearable device outside the wind turbine. Then analyze the location of the operator. The latitude and longitude coordinates determined by the built-in GPS positioning device of the mobile terminal indicate that the operator is in the wind turbine. According to the operating specifications, the operator should wear safety equipment suitable for the wind turbine. The position of the personnel does not match the safety equipment worn, that is, the safety equipment is not used correctly by the operator.

On the basis of the embodiment shown in Figure 1, the method for monitoring the safety status of offshore wind farm operators of the present invention has the following technical effects:

On the one hand, by introducing a tag card to trigger the tag card to send status information to monitor the status information of the safety equipment when the safety equipment is used correctly by the operator, to ensure the accuracy of monitoring;

On the other hand, according to whether the status information of the safety equipment equipped by the operator is monitored, a safe/unsafe status result is generated to identify whether the operator is inside/outside the wind turbine, making the generated status result more accurate.

In addition, when the status results show that the operator is neither outside the wind turbine nor inside the wind turbine, an alarm is given to remind the operator to operate in accordance with safety regulations, which minimizes the safety risk of the operator and reduces the occurrence of accidents Rate.

Fig. 3 is a schematic diagram of the application scene of the method for monitoring the safety status of offshore wind farm operators provided by the present invention. The specific application of the embodiment of the present invention will be further and more intuitively described below in combination with specific application scenarios.

After offshore wind farm operators (such as operation and maintenance personnel) go out to sea with the operation and maintenance ship, there are two situations for their working environment, namely outside the wind turbine and inside the wind turbine. First of all, when the operation and maintenance personnel are outside the wind turbine, if the operation and maintenance personnel wear life jackets correctly, the relatively mature electromagnetic induction zipper pullers on the market are used on the life jackets. There is a thimble on the top of the zipper head. The tag card, here, the tag card can be equivalent to the monitoring device in the third embodiment, the tag card sends the status information of the safety equipment to the mobile terminal held by the operation and maintenance personnel through the wireless network, and the mobile terminal forwards the status information of the safety equipment, and the offshore wind power The field wireless communication network transmits to the monitoring station of the offshore wind power project department or the database of the centralized control center server. Here, the centralized control center server can be equivalent to the central controller in the third embodiment. The built-in GPS positioning device of the standard mobile terminal for the operation and maintenance personnel can determine the position identification of the operation and maintenance personnel through the GPS positioning function, thereby generating a safe status result including the location identification of the operation and maintenance personnel outside the wind turbine, and On the monitoring interface, the status of the operation and maintenance personnel is visually displayed as safe. In addition, the location identification of the operation and maintenance personnel can be the latitude and longitude coordinates, and at the same time, it is displayed on the monitoring interface of the centralized control center in real time. If no status information is detected, it means that the operation and maintenance personnel have not worn the corresponding safety equipment in accordance with the safety operation specifications, and there will be corresponding alarm information on the monitoring interface.

Secondly, when the operation and maintenance personnel are in the wind turbine, they can use multi-functional wireless routers, tags or other terminals, as well as the optical fiber network inside the offshore wind turbine to build an internal positioning system for the offshore wind turbine. The locator in the positioning system can automatically The tag or terminal of the network attachment is identified, and the information of the tag or terminal is processed by the locator and transmitted to the background server through the network channel. The IP address of the locator is uniquely determined with the platform position in the offshore wind turbine, and the three-dimensional interface of the offshore wind turbine simulation The location information of the person will be displayed.

Specifically, in order to increase the reliability and redundancy of the internal positioning system of the offshore wind turbine, the internal positioning system of the offshore wind turbine integrates multiple low-frequency activators and antennas. The operation and maintenance personnel wear safety clothing when they are in the wind turbine. The safety clothing is equipped with a label card. The power supply circuit of the label card connects the lock of the safety clothing in series. When the safety clothing is worn correctly, the power supply circuit of the label card is turned on and the label card The card starts to work, and receives the low-frequency activation signal continuously sent by the low-frequency activator, and converts it into a wireless signal data containing the status information of the safety clothing and sends it back to the antenna.

The antennas in the system have their own corresponding identification. The antenna identification database is pre-established in the system. The installation position of the antenna in the wind turbine corresponds to the identification one by one. The antenna receives the wireless signal data returned by the tag card, that is, the tag card Feedback the status information of the safety clothing to the internal positioning system of the offshore wind turbine, and the status information is transmitted to the database of the centralized control center through the network of the internal positioning system of the wind turbine, indicating that the status information of the safety clothing is monitored, and at the same time, the identification of the monitored antenna can be obtained The location identification of the operation and maintenance personnel, so as to generate the safe status result of the operation and maintenance personnel in the wind turbine including the location identification of the operation and maintenance personnel, and visually display the status of the operation and maintenance personnel as safe on the monitoring interface. If it is not detected, it means that the operation and maintenance personnel have not worn the corresponding safety equipment in accordance with the safety operation specifications, and there will be corresponding alarm information on the monitoring interface.

The above method can only make a preliminary judgment on the location of the operation and maintenance personnel, that is, determine whether they are located in the wind turbine, but cannot obtain a more accurate location of the operation and maintenance personnel. Here, the precise location of the tag card is calculated based on RSSI ranging technology The location of the tag card is the location of the operation and maintenance personnel, so as to realize the positioning function. In addition, the three-dimensional model diagram of the offshore wind turbine in the monitoring interface, according to the status of the monitoring safety clothing, queries the corresponding address in the database, and highlights it on the monitoring interface. The feedback signal of the label is also transmitted to the offshore wind turbine through the wireless network The switch of the relay base station at the bottom of the tower is transmitted to the server of the booster station through the submarine optical fiber LAN. After the data information is encrypted by the firewall, it is transmitted to the centralized control center through the virtual private network (VPN) channel established on the IP network. In the server, the monitoring management receives and saves the information of the tag card according to the need, combines with the actual map, displays the location of the tag card in real time on the map, and displays the location and movement track of the operation and maintenance personnel.

When an alarm message appears on the above-mentioned monitoring interface, the location information of the operation and maintenance personnel can be judged first through the safety status monitoring system of the offshore wind farm operators, and then the corresponding responsible person can be reminded through the wireless communication network of the offshore wind farm to reduce the safety risk of the operation and maintenance personnel. to the minimum.
