[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0048] In this application, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. The term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0049] The present invention can be used in numerous general-purpose or special-purpose computing device environments or configurations. For example: personal computers, server computers, handheld devices or portable devices, tablet devices, multi-processor devices, distributed computing environments including any of the above devices or equipment, and so on.

[0050] An embodiment of the present invention provides a lightning protection module status detection system. The system structure diagram of this system is as Figure 1 shown, and specifically includes:

[0051] A status detection plug-in 100, a collection unit 200, and a monitoring and maintenance unit 300;

[0052] The status detection plug-in 100 is used to output a status signal corresponding to the working status of the lightning protection module to the collection unit. Among them, the status detection plug-in 100 and the lightning protection module to be detected are arranged inside the analog network disk. The status detection plug-in 100 has a detection function for detecting the status of the lightning protection model. Determine the working status of the lightning protection module according to the status detection and output the corresponding status signal.

[0053] The collection unit 200 is used to collect the status signal and forward the status signal to the monitoring and maintenance unit. The collection unit 200 is equivalent to an information transfer component and is used for transmitting the status signal.

[0054] The monitoring and maintenance unit 300 is used to send a fault warning message corresponding to the lightning protection module when the status signal indicates that the lightning protection module has failed. The monitoring and maintenance unit 300 can be connected to devices such as the user's computer or handheld terminal, and send a fault warning message through the terminal device. Or send a fault warning message by sounding a horn or lighting a lamp. The collection unit and the monitoring and maintenance unit are connected through CAN.

[0055] Optionally, in addition to sending a fault warning message, the monitoring and maintenance unit 300 can also display the circuit information of the track circuit to which the lightning protection module detected by the status detection plug-in 100 belongs. Different from the existing configuration, the monitoring and maintenance unit 300 adds a lightning protection module status monitoring partition and sets a program alarm function on the basis of displaying information such as output voltage, current, input voltage, and current of the power output.

[0056] In the lightning protection module status detection system provided by the embodiment of the present invention, the status detection plug-in 100 can implement a preliminary monitoring of the lightning protection module, determine whether the lightning protection model is in a normal working state or a fault state, and output the corresponding status signal to the acquisition unit 200. The acquisition unit 200 performs signal transmission so that the monitoring and maintenance unit 300 sends a fault warning message when the status signal indicates that the lightning protection module has a fault.

[0057] By applying the system provided by the embodiment of the present application, the working state of the lightning protection module can be automatically obtained, and a fault warning message is sent when the working state indicates that the lightning protection module has a fault, so as to ensure that the staff can quickly process it after receiving the fault warning message and avoid damage to electrical equipment.

[0058] Reference Figure 2 , the status detection plug-in 100 includes: a tripping device and a base;

[0059] The tripping device is connected to the lightning protection module, and when the working state of the lightning protection module is a fault state, the internal switch state of the tripping device is changed;

[0060] The base is arranged inside the analog network disk;

[0061] The base is used to place the lightning protection module and fix the tripping device; when the internal switch state of the tripping device changes, a status signal corresponding to the current internal switch state of the tripping device is output to the acquisition unit.

[0062] It should be noted that the lightning protection module is fixed on the base to protect the analog network disk from being directly struck by lightning. The tripping device is connected to the working node of the lightning protection module. When the lightning protection module is in a normal working state, the connection between the working node of the lightning protection module and the tripping device is in an open state, that is, the internal switch state of the tripping device is in an open state. When the working state of the lightning protection module is a fault state, the connection between the working node of the lightning protection module and the tripping device is conducted, and at this time, the internal switch state of the tripping device is in a connected state.

[0063] Specifically, the status detection plug-in 100 outputs a status signal corresponding to the working state of the lightning protection module to the acquisition unit 200, specifically for:

[0064] Determine the working state of the lightning protection module based on the internal switch state of the tripping device;

[0065] Output a status signal corresponding to the working state to the acquisition unit.

[0066] Further, when the working state of the lightning protection module is a fault state, the internal switch state of the tripping device is switched to the conducting state; when the working state of the lightning protection module is a normal state, the internal switch state of the tripping device is switched to the open state.

[0067] It should be noted that when the tripping device is in the open state, the base cannot output a status signal to the acquisition unit 200. In the case where the acquisition unit 200 does not acquire a status signal, it indicates that the lightning protection module has not failed. When the tripping device is in the conducting state, the tripping device can output a status signal to the acquisition unit 200. When the acquisition unit 200 obtains the status signal, it indicates that the lightning protection module has failed.

[0068] Reference Figure 2 , the status detection system of the lightning protection module further includes: a printed circuit board;

[0069] The printed circuit board includes a backplane main body, a connector, and a pin;

[0070] The connector is welded to the backplane main body. One end of the connector is welded to one end of the pin, the other end of the pin is connected to the output end of the status output loop, and the other end of the connector is connected to the acquisition unit.

[0071] It should be noted that the backplane module is a board for externally connecting the status detection plug-in 100 provided on the original analog network disk. Its function is to connect the lead-out wire of the base to this backplane main body, so as to externally lead out the alarm signal.

[0072] Reference Figure 3 , the base in the status detection plug-in 100 includes: a status output loop;

[0073] Among them, the status output loop includes: diodes connected in reverse series (such as Figure 3 PP in Figure 3 ), a first resistor (such as Figure 3 R1 in Figure 3 ), a second resistor (such as Figure 3 R2 in Figure 3 ), a third resistor (such as Figure 3 R3 in Figure 3 ), a fourth resistor (such as

[0074] The reverse-connected diodes are connected in parallel with the tripping device;

[0075] One end of the first resistor is connected to the first end of the reverse-connected diodes, and the other end is connected to the power supply terminal;

[0076] One end of the second resistor is connected to the second end of the reverse-connected diodes, and the other end is connected to the first end of the first capacitor;

[0077] The second end of the first capacitor is connected to the power supply terminal;

[0078] The second capacitor is connected in parallel with the third resistor, wherein one end of the parallel connection is grounded, and the other end is connected to the first end of the first capacitor mentioned above;

[0079] The first end of the fourth resistor is connected to the first end of the first capacitor, and the second end is connected to the first end of the voltage control module;

[0080] The first end of the voltage control module is connected to the output terminal, the second end is grounded, and the third end is connected to the power supply terminal.

[0081] It should be noted that the first end and the second end of the tripping device in this state output loop are the working nodes of the tripping device. When the tripping device is in the normal working state, the ends of the first resistor and the second resistor connected to the tripping device are in the open state, the state output loop is open, and the state signal output to the acquisition unit 200 is a low-level signal. In the fault state of the lightning protection module, the ends of the first resistor and the second resistor connected to the tripping device are conducting, the state output loop is conducting, and after the power supply from the power supply terminal enters this state output loop, it passes through various electrical devices such as resistors and capacitors, and outputs a high-level signal of the state signal to the acquisition unit.

[0082] Further, the voltage control module includes:

[0083] The first diode (such as Figure 3 PN1 therein) and the second diode (such as Figure 3 PN2 therein);

[0084] The anode of the first diode is grounded, and the cathode is connected to the output terminal;

[0085] The anode of the second diode is connected to the output terminal, and the cathode is connected to the power supply terminal;

[0086] The voltage control module is used to control the maximum voltage of the high level output at the output terminal not to exceed the target voltage.

[0087] For example: the input voltage of the power supply terminal is 3.3V. When it is necessary to output a high-level signal through the output, the voltage amplitude of the highest voltage is limited within 3.3V.

[0088] It should also be noted that the resistor connected to the output terminal (such as Figure 3 R4 in

[0089] ) is used to limit the current amplitude at the output terminal to be less than the target current.

[0090] (1) The simulated network disk, different from the existing devices, adds the status acquisition of the lightning protection module. There is a status detection plug-in inside, and a base with a telecommunication function is set in the status detection plug-in. The wiring of the base can be led out to the acquisition unit and sent to the monitoring and maintenance unit to update the status of the lightning protection module in real time.

[0091] (2) The simulated network disk, different from the existing devices, has a printed circuit board inside. The backplane main body in the printed circuit board is welded with a connector, and pins are welded on the reverse side of the connector for the electrical network to weld the lead-out wire of the lightning protection module base and connect it to the acquisition unit.

[0092] (3) The acquisition unit, different from the existing configuration, adds a acquisition channel, connects to the connector in the printed circuit board welded on the simulated network disk through a cable, and uploads the acquired status signal to the monitoring and maintenance unit through the CAN line.

[0093] (4) The monitoring and maintenance unit, different from the existing configuration, can add the status monitoring area of the lightning protection module on the basis of displaying information such as output voltage, current, input voltage, current, etc., and set the program alarm function.

[0094] It should be noted that the status detection plug-in mainly includes a tripping device and a status output circuit set in the base.

[0095] Such as Figure 3 in the circuit diagram shown, the working nodes of the tripping device (such as Figure 3 points 1 and 2 shown) are connected to the status output circuit. If the lightning protection module is normal, the working nodes are disconnected, and there is no path at this time. The potential at OUT (output terminal) is ground, which is a low level; if the lightning protection module fails, the working nodes are conducted, and the whole circuit forms a loop. In the loop, the first resistor R1, the second resistor R2, and the third resistor R3 are connected in series. The potential at OUT is the voltage division of R3, which is 3V, and it is a high level. The acquisition unit acquires the signal at OUT to judge the quality of the lightning protection module.

[0096] Based on the status detection system of the lightning protection module provided in the above embodiments, it can realize the real-time monitoring and automatic alarm of the status of the lightning protection module of the on-site simulated network disk, saving manpower; it can timely feedback the damage information of the lightning protection module, thereby protecting the simulated network disk from lightning strikes and protecting the normal operation of the on-site equipment.
