The maintenance of the group 100, therefore, is low in maintenance costs.

The following describes an application scenario of the sensor module 100 provided by the present invention for office lighting. It is assumed that the illuminance sensor and the infrared sensing component are used in the sensing module 1. When the person enters the office area, the infrared sensing component in the sensing module 1 collects infrared radiation information of the human body. The illuminance sensor collects illuminance information in the environment. The setting unit 13 in the sensing module 1 can set the sensitivity of the infrared sensor and the highest illumination threshold when the illumination is turned on. When the infrared radiation of the human body collected by the infrared sensing component reaches the preset intensity, the personnel have completely entered the office area. The illuminance in the environment collected by the illuminance sensor is less than the preset ambient illuminance threshold, indicating that the brightness of the office area is insufficient at this time, and lighting of the lighting device is required. This information is fed back to the control unit 12 in the sensing module 1 so that the control unit 12 controls the lighting capabilities of the lighting device to match the current lighting environment.

The second electrical interface 20 of the communication module 2 is mechanically coupled to the first electrical interface 10 of the sensing module 1 for electrical connection. Moreover, the communication module 2 can use at least one of a WIFI communication protocol signal, an RS485T communication protocol signal, a ZIGBEE communication protocol signal, a Z-WAVE communication protocol signal, a DALI signal, and a DMX512 communication protocol signal to interact with an external system for environmental information. Therefore, the external system can store the environmental information collected by the sensing module 1. Further, for an external system having a control function, the external system can transmit a corresponding control command to the communication module 2. The control command is sent by the communication module 2 to the control unit 12 in the sensing module 1 so that the control unit 12 adjusts the illumination capability of the lighting device.

The fourth electrical interface 33 of the power module 3 and the third electrical interface 22 of the communication module 2 The mechanical mating also achieves an electrical connection. The power frequency AC source interface 31, the bus power interface or the DC source interface 32 of the power module 3 can introduce external power, and when the power module 3 is implanted into the battery pack, internal supply of electrical energy can be realized. The power module 3 is electrically connected to the third electrical interface 22 of the communication module 2 via the fourth electrical interface 33 to directly supply power to the communication module 2. The communication module 2 is electrically connected to the first electrical interface 10 of the sensing module 1 via the second electrical interface 20 to further distribute the obtained electrical energy.

The above is a complete application scenario of the sensor module 100. The present invention also provides a case where a part of the sensor module 100 is used for application.

Specifically, a sensor module can communicate with an external system, including:

The sensing module 1 is configured to collect environmental information, and is provided with a first electrical interface 10;

The communication module 2 is provided with a second electrical interface 20 electrically connected to the first electrical interface 10, and the environmental information collected by the sensing module 1 is acquired by the second electrical interface 20, the communication module 2 can interact with the external system of the environmental information, the communication module 2 is provided with a third electrical interface 22;

The power module 3 is provided with a fourth electrical interface 33 electrically connected to the third electrical interface 22, and the electrical energy of the sensing module 1 and the communication module 2 is supplied through the fourth electrical interface 33;

The first electrical interface 10 is mechanically coupled to the second electrical interface 20 to achieve electrical connection, and the third electrical interface 22 is mechanically coupled to the fourth electrical interface 33 to achieve electrical connection.

It should be noted that the sensor module can be mainly composed of the sensing module 1, the communication module 2 and the power module 3 of the sensor module 100. Since the structure of the sensing module 1, the communication module 2, and the power module 3 has been described in detail, it will not be described here. Similarly, since the power module 3, the communication module 2, and the sensing module 1 are separate modular structures, when one of the modules fails, the module that replaces the failure can be replaced to complete the maintenance of the sensor module, and thus the maintenance cost is low. .

The invention also provides a sensor module comprising:

The sensing module 1 is configured to collect environmental information, and is provided with a first electrical interface 10;

The power module 3 is provided with a fourth electrical interface 33 electrically connected to the first electrical interface 10, and the electrical energy of the sensing module 1 is supplied through the fourth electrical interface 33;

The first electrical interface 10 and the fourth electrical interface 33 are mechanically coupled to each other to achieve electrical connection.

In the embodiment of the present invention, the fourth electrical interface 33 of the power module 3 is connected to the front The second electrical interface 20 of the letter module 2 can be arranged as the same universal interface. At this time, the power module 3 is electrically connected to the first electrical interface 10 of the sensing module 1 through the fourth electrical interface 33 to supply the sensing module 1 with electrical energy. The sensing module 1 makes a preset response according to the collected environmental information.

Taking the application scenario of the office lighting as an example, when the person enters the office area, the sensing module 1 can control the power output according to the collected environmental information. The only difference is that the sensor module does not interact with external systems. Similarly, since the power module 3 and the sensing module 1 are separated modular structures, when one of the modules fails, the module that replaces the corresponding failure can complete the maintenance of the sensor module, and thus the maintenance cost is low.

The invention also provides a sensor module comprising a sensing module 1. The sensing module 1 is configured to collect environmental information, and is provided with a first electrical interface 10;

The first electrical interface 10 is used for mechanical mating while achieving electrical connection.

The sensor module here is mainly composed of the sensing module 1.

Similarly, since the sensing module 1 is a split modular structure, when the sensing module 1 fails, the sensor module 1 can be replaced by replacing the corresponding failed sensing module 1, and thus the maintenance cost is low.

The specific embodiments of the present invention have been described in detail with reference to the preferred embodiments of the present invention.
