Description

A distribution frame detection device and detection method thereof

technical field

The invention relates to a detection device for a distribution frame and a detection method thereof.

Background technique

A basic principle of designing patch panels is to help network administrators manage the wiring system. With the development of integrated wiring technology, more and more people hope to adopt electronic wiring system, which is often called intelligent wiring system.

Generally, the electronic distribution frame can be divided into port detection type and link detection type according to its principle; it can be divided into single distribution frame mode and double distribution frame mode according to its wiring structure; line and 9-core jumper.

Among them, the principle of the port detection method is to install a micro switch on the port. Once a jumper is inserted, the micro switch will be touched, and the micro switch will notify the system that the port has a jumper inserted. The opposite is also the same, if there is already a jumper plug in the original port, once the jumper in this port is pulled out, the system will immediately notify the system that there is no jumper plug in this port. The advantage of the port detection method is that ordinary jumpers can be used. The problem is that it can only detect whether there is a jumper plug in the port, but does not know where the jumper plugged into the plug is connected.

The principle of the link detection method is to add a wire to the ordinary jumper, which is generally called a 9-core jumper. The electronic distribution frame based on the link detection method uses this wire to determine the link status of the port. When this 9-core jumper is connected to two ports, the system will detect the link relationship between the two ports through the 9th core and update it to the link database. The advantage of the link detection method is that it can make the jumper operation zero error, but the problem is that if a common jumper is inserted, the system cannot detect the plugging and unplugging of the port, which will bring security risks to the wiring system, and because the system Continuous polling is used for detection, so the response time will become longer as the network scale expands.

Contents of the invention

In order to solve the problems existing in the existing detection devices, the present invention provides a distribution frame detection device and its detection method. The technical solutions adopted are:

The device includes a distribution frame, a mounting board and a printed board assembly. The printed board assembly is fixed on the distribution frame through the mounting board. The rear part of the distribution frame is provided with a connector connected to the scanner. There are multiple LED lights and ports corresponding to the LED lights. Micro switches are fixed on the front of each port. The printed board assembly is located above each micro switch and a trigger switch is fixed. There are contacts inside each port. , when a plug with a nine-core jumper is inserted into any port, the micro switch can move up and touch the corresponding trigger switch, and the ninth core on the plug can contact the corresponding contact.

The detection method is: insert a plug with a nine-core jumper into the port, the micro switch at the front end of the port moves upwards under the action of external force, and touches the trigger switch welded on the printed board assembly during the movement, thereby notifying the device that the port has The jumper is inserted, and correspondingly enters the scanning state of the corresponding port; when the plug with the core jumper is fully inserted into the port, the ninth core wire on the plug touches the corresponding contact inside the port, and then passes through the ninth core on the corresponding port. The wires form a scan loop to detect the link relationship between the two ports into which the jumper wire is inserted.

The port trigger switch of the distribution frame of the present invention can detect the insertion state of the port, and at the same time, the link scanning line of the distribution frame can detect the link state of the port. At the same time, this distribution frame can support both a single distribution frame and double distribution frames. For a single distribution frame, ordinary jumpers can be used to trigger the detection of jumper insertion and removal through ports. For double distribution frames, 9-core jumpers can be used. It can not only detect whether the jumper is plugged or unplugged through the port trigger detection, but also detect whether the port link is correct through scanning.

The present invention is compatible with the advantages of the port detection technology and the link detection technology, overcomes the shortcomings of simply using the port detection technology or the link detection technology, and at the same time, through the combination of the two methods, the traditional round-robin scanning method is replaced by the method of triggering and starting scanning , which greatly improves the detection speed of large-scale networks, and has better security and reliability.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in FIGS. 1 and 3 , the printed board assembly 3 is fixed inside the distribution frame 1 through the mounting plate 2 , and a connector 8 connected to the scanner is provided at the rear of the distribution frame 1 . As shown in Figure 2, a plurality of LED lamps 5 and ports 7 corresponding to the LED lamps 5 are provided on the printed board assembly 3, micro switches 4 are fixed on the front ends of each port 7, and the printed board assembly 3 is located in each micro A trigger switch is fixed at the position above the trigger switch 4, and contacts are provided inside each port 7.

As shown in Figure 4, when the plug 6 with a 9-core jumper is inserted into the port 7, the microswitch 4 at the front end of the port moves upwards under the action of external force, and touches the trigger switch welded on the printed board assembly during the movement, thereby Notify the device that there is a jumper inserted in this port, and enter the corresponding port scanning state accordingly. When the plug 6 with a nine-core jumper is fully inserted into the port 7, the ninth core wire on the plug 6 touches the corresponding contact inside the port 7, and then forms a scanning loop through the ninth core wire on the corresponding port, thereby detecting Link relationship to the two ports that the jumper is plugged into.

The detection device transmits the trigger signal of the detection switch and the scanning signal of the link to the scanner through the connector 8 to form a plug-in detection of the distribution frame port 7; operation, the signal can be transmitted from the scanner back to the inside of the device through the connector 8, and the corresponding LED light 5 that needs to be operated will be lit, thereby guiding the jumper plugging and unplugging operation.
