Description

Technical Field

[0001] The utility model relates to the technical field of motor vehicle multiple unit fault detection, and in particular to a device for troubleshooting breakpoint faults in a control circuit of a Fuxing intelligent motor vehicle multiple unit. Background Art

[0002] With the rapid development of China's high-speed railway, the equipment level and technical content of high-speed railway have reached the world's leading level. The emergence of intelligent EMUs in recent years has once again improved my country's high-speed railway. In the production and manufacturing of intelligent EMUs, the whole train debugging is an important link, which is related to whether the various functions of the intelligent EMU can be realized normally.

[0003] The intelligent EMU has nearly 10,000 connection points and dozens of control circuits, and each control circuit also has dozens to hundreds of connection points. For example, the pantograph circuit is responsible for controlling the raising of the pantograph and introducing AC25KV from the contact network to the vehicle high-voltage equipment; the main circuit breaker circuit is responsible for closing the main circuit breaker and sending the AC25KV introduced by the pantograph to the main transformer; the EMU safety circuit is responsible for monitoring the braking stability of the EMU, etc. Each control circuit has its own function, and any circuit must not have problems, which is directly related to the stability of the EMU operation.

[0004] During the debugging or operation stage of the entire vehicle, there may be breakpoints in the control circuit or loose connections at the control circuit connection points, which will cause the control circuit to be unable to be established and the control circuit to function intermittently, affecting the vehicle's debugging cycle and the stability of the vehicle's functions.

[0005] The traditional troubleshooting method requires that the connection points of the vehicle's control circuit be checked one by one, and the fault point be promptly handled after it is found. The traditional troubleshooting method has the following disadvantages: First, if each connection point is checked, it is time-consuming and labor-intensive. Second, during the inspection of the connection point, repeated plugging and unplugging of the terminal and plug can easily cause secondary damage to the connection point, increasing safety hazards. Utility Model Content

[0006] The utility model aims to solve the technical problems in the prior art and provides a device for troubleshooting breakpoints in a control circuit of a Fuxing intelligent EMU.

[0007] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0008] A device for troubleshooting breakpoints in a control circuit of a Fuxing intelligent EMU, the device comprising: a circuit connection point, a second power supply line, a second relay, an indicator light, and a counter connected in sequence;

[0009] The breakpoint fault troubleshooting device is connected to the fault control circuit of the vehicle through a cable segment; the fault control circuit includes: a battery, a control device, a first power supply line and a first relay connected in sequence;

[0010] The circuit connection point is used to connect the breakpoint fault troubleshooting device to the fault control circuit of the vehicle; the second power supply line is a transmission medium for the fault control circuit to supply power to the breakpoint fault troubleshooting device; after the second relay is energized, the corresponding contact is closed, so that the indicator light is lit and the counter counts;

[0011] The battery is used to supply power to the vehicle's control device, the first power supply line and the first relay; the control device is used to issue a circuit establishment instruction to the fault control circuit; the first power supply line is a transmission medium for supplying power to the fault control circuit;

[0012] After the control device issues a circuit establishment instruction:

[0013] If the first relay is energized, the fault control circuit is established, the indicator light is on, the counter counts cumulatively, and there is no fault in this section of the fault control circuit;

[0014] If the first relay is not energized, the fault control circuit is not established, the indicator light does not light up, the counter does not accumulate counts, and there is a fault in this section of the fault control circuit.

[0015] In the above technical solution, the control device sends a control instruction to the fault control circuit of the vehicle through a control operation.

[0016] In the above technical solution, the count of the counter indicates the number of times the section of the breakpoint fault troubleshooting device connected to the fault control circuit is powered on.

[0017] In the above technical solution, when the counter is counting, if the first power supply line works normally, the second relay is powered and closed through the second power supply line, the contact of the second relay is closed to light up the indicator light, and the counter counts once.

[0018] The utility model has the following beneficial effects:

[0019] The utility model of the control circuit breakpoint fault troubleshooting device of the Fuxing intelligent EMU can effectively and quickly troubleshoot the fault point when a control circuit breakpoint fault occurs during the whole train debugging stage or the operation stage of the vehicle, thereby shortening the troubleshooting range of the vehicle's fault control circuit breakpoint, improving the fault troubleshooting efficiency and reducing labor.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0032] The entire train has nearly 10,000 connection points, dozens of vehicle control circuits, and each control circuit has hundreds of connection points. If the control circuit has a breakpoint or a connection point has a virtual connection, it will directly affect the overall operating performance of the vehicle. At this time, the vehicle's control circuit needs to be checked and the fault point needs to be dealt with in a timely manner after it is found.

[0033] The inventive concept of the utility model is to connect the control circuit breakpoint fault detection device to the control circuit, and to quickly and effectively detect the fault point through comparative feedback of a plurality of indicator lights and counters.

[0034] Figure 1 The system structure diagram for realizing rapid troubleshooting of the control circuit breakpoint troubleshooting device. The system consists of a vehicle fault control circuit 100 and a breakpoint troubleshooting device 200. The breakpoint troubleshooting device 200 is connected to the vehicle fault control circuit 100 in sections via cable 12. The vehicle fault control circuit 100 is a built-in component of the entire train, and is composed of a first power supply line 103, a first relay 104, a battery 101 (DC110V control power supply), and a control device 102. The breakpoint troubleshooting device 200 is not a built-in component of the vehicle, and is composed of a circuit connection point 201, a second power supply line 202, a second relay 203, an indicator light 204, and a counter 205. Multiple breakpoint troubleshooting devices 200 are connected to the vehicle fault control circuit 100 in sections via cable 12, such as Figure 5 As shown, by comparing the feedback from the indicator light 204 and the counter 205 of each breakpoint troubleshooting device 200 in the vehicle's fault control circuit 100, it is possible to analyze that the fault point is in a certain section of the fault control circuit 100, and troubleshoot this section of the fault, thereby avoiding troubleshooting each connection point of the entire fault control circuit 100 one by one.

[0035] Figure 2The structure diagram of the fault control circuit of the vehicle. The battery 101 is mainly responsible for supplying power to the fault control circuit 100 of the vehicle; the control device 102 is responsible for issuing instructions to the fault control circuit 100 of the vehicle to establish its control circuit; the first power supply line 103 serves as a transmission medium for supplying power to the fault control circuit 100 of the vehicle; after the first relay 104 is energized, it indicates that the fault control circuit 100 of the vehicle is established and there is no problem with the fault control circuit 100 of the vehicle. If the first relay 104 is not energized after the control device 102 issues an instruction, it indicates that the fault control circuit 100 of the vehicle is not established and there is a fault. The function of the battery 101 is to supply power to the control device 102, the first power supply line 103 and the first relay 104 of the vehicle. The control device 102 is manually operated to issue control instructions to the fault control circuit 100 of the vehicle. The control device 102 issues a control instruction to transmit the DC110V power through the transmission medium of the first power supply line 103, and finally the first relay 104 is powered. The power-on of the first relay 104 indicates that the vehicle's fault control circuit 100 is established. If the first relay 104 of the vehicle's fault control circuit 100 is not powered at this time, it indicates that there is a breakpoint fault in the vehicle's fault control circuit 100, which needs to be checked.

[0036] Figure 3 For Figure 2 The structure diagram of the breakpoint fault troubleshooting device. The circuit connection point 201 is mainly responsible for connecting the breakpoint fault troubleshooting device 200 to the vehicle's fault control circuit 100; the second power supply line 202 serves as a transmission medium for the vehicle's fault control circuit 100 to supply power to the breakpoint fault troubleshooting device 200; after the second relay 203 is energized, the corresponding contact closes, so that the indicator light 204 lights up and the counter 205 counts; the lighting of the indicator light 204 directly reflects that the power supply of the section in the vehicle's fault control circuit 100 where the breakpoint fault troubleshooting device 200 is connected is normal; each count of the counter 205 indicates the number of times the section in the vehicle's fault control circuit 100 where the breakpoint fault troubleshooting device 200 is energized, such as Figure 4As shown. The function of the circuit connection point 201 is to connect the breakpoint fault troubleshooting device 200 to the fault control circuit 100 of the vehicle. The second power supply line 202 serves as a transmission medium for a certain section of the fault control circuit 100 of the vehicle to supply power to the breakpoint fault troubleshooting device 200. If the first power supply line 103 works normally, the second relay 203 will be powered and closed through the second power supply line 202, and the contact closure of the second relay 203 will light up the indicator light 204, and the counter 205 will count once, indicating that the power supply of the section of the circuit where the breakpoint fault troubleshooting device 200 is connected to the fault control circuit 100 of the vehicle is normal. If the indicator light 204 of the breakpoint fault troubleshooting device 200 is not lit and the counter 205 is not counted, it means that the power supply of the section of the circuit where the breakpoint fault troubleshooting device 200 is connected to the fault control circuit 100 of the vehicle has a breakpoint.

[0037] Figure 4 The circuit diagram of the breakpoint fault troubleshooting device 200 is shown in FIG. It is composed of a positive and negative connection point, a second relay 203, an indicator light 204, and a counter 205. The positive and negative connection points are connected to the fault control circuit 100 of the vehicle. If the power supply is normal, the second relay 203 is energized, and the corresponding contacts are closed, which will eventually allow the indicator light 204 to be energized and the counter 205 to accumulate counts. If a breakpoint occurs in the fault control circuit 100 of the power supply vehicle, the power supply is abnormal, the second relay 203 is not energized, the corresponding contacts do not operate, the indicator light 204 does not light up, and the counter 205 does not accumulate counts. This indicates that a breakpoint problem occurs in this section of the fault control circuit 100 connected to the vehicle. This section is checked to shorten the scope of the breakpoint check.

[0038] Figure 5The figure is a schematic diagram of troubleshooting the breakpoint of the control circuit. When the first power supply line 103 of the fault control circuit 100 of the vehicle fails, multiple breakpoint troubleshooting devices 200 can be connected to the first power supply line 103 of the fault control circuit 100 of the vehicle in sections. If the indicator light 204 of a breakpoint troubleshooting device 200 is not lit, it means that the first power supply line 103 of the fault control circuit 100 of the vehicle in this section has a breakpoint. The circuit of this section is checked, which shortens the troubleshooting scope. The accumulated times of the counters 205 of the multiple breakpoint troubleshooting devices 200 can also be compared. If the value of the counter 205 of a breakpoint troubleshooting device 200 is less than the values ​​of other counters 205, it means that the first power supply line 103 of the fault control circuit 100 of this section of the vehicle has a breakpoint. If the value of the counter 205 of a breakpoint troubleshooting device 200 is greater than the values ​​of other counters 205, it means that the first power supply line 103 of the fault control circuit 100 of this section of the vehicle is powered normally. That is to say, the more breakpoint fault troubleshooting devices 200 are connected to the first power supply line 103 of the vehicle's fault control circuit 100, the faster the control circuit fault is troubleshooted and the smaller the troubleshooting range is.

[0039] The utility model of the control circuit breakpoint fault troubleshooting device of the Fuxing intelligent EMU can effectively and quickly troubleshoot the fault point when a control circuit breakpoint fault occurs during the whole train debugging stage or the operation stage of the vehicle, thereby shortening the troubleshooting range of the vehicle's fault control circuit breakpoint, improving the fault troubleshooting efficiency and reducing labor.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
