Abstract
Description
Technical Field
[0001] The utility model relates to an integrated device for RIOM board monitoring and signal simulation of urban rail vehicles. Background Art
[0002] The train network control system is responsible for the control, monitoring and diagnosis of the EMU traction, braking, bogie, auxiliary power supply, door, air conditioning and other systems. The remote input (DI) / output (DO) module (RIOM) realizes the acquisition and control of the main signals of the 110V control circuit. It acquires and controls the analog or digital signals of the driver controller, the direction handle and other signals. There are digital input interface, digital output interface and analog input interface on RIOM.
[0003] During the production and commissioning of subway and Dujiangyan vehicles, it is often necessary to disassemble the Harding plug to measure the electricity when troubleshooting I / O faults. It is difficult to measure the electricity of the Harding plug with a multimeter (the tip of the test lead is large), which is not conducive to troubleshooting; there are also cases where the plug and the board (the board is equipped with functional circuits to realize the input / output function, and the board is equipped with connectors for electrical connection with the Harding plug. The connector corresponds to the number of input / output interfaces and is electrically connected. When the input is connected to the signal, the corresponding output interface has an output) are not grounded when they are separated, and they are grounded after the plug is plugged in. For this type of fault, it is impossible to directly determine whether it is a problem with the board or the plug, and it is difficult to start; in subway debugging, some network I / O tests also require the manufacturer to cooperate in signal simulation (using a computer to simulate the signal), which lengthens the debugging cycle.

[0028] The technical solution claimed in this application is further introduced in detail here with reference to the accompanying drawings and specific implementation methods.
[0029] Please refer to Figure 1 , 2 The device provided by the utility model includes an indicator light LED1 for monitoring the Harding plug, an indicator light LED2 for monitoring the RIOM board, a knob S1 and a controlled switch SB1. One end of the indicator light LED1 is divided into two paths, which respectively serve as the lead-out terminal A and the lead-out terminal B of the device. The lead-out terminal A is used to be electrically connected to the Harding plug (to be tested), and the lead-out terminal B is used to be electrically connected to the RIOM board (I / 0 interface); the other end is electrically connected to the A end of the knob S1; the B end of the knob S1 serves as the lead-out terminal C of the device for connecting the negative line. One end of the indicator light LED2 serves as the lead-out terminal D of the device, which is used to be electrically connected to the Harding plug (to be tested), and the other end is electrically connected to the A end of the knob S1; the controlled switch SB1 is located on the lead-out terminal D (such as Figure 1 ) or between the indicator LED2 and the A end of the knob S1 (as shown Figure 2 as shown).
[0030] When in use, first turn on the knob S1, electrically connect the lead-out terminals A and D to the Harding plug (under test), and electrically connect the lead-out terminal B to the RIOM board; if the Harding plug (under test) can be powered on normally, the X1-1 terminal is powered on, and at this time, the lead-out terminal A, the indicator light LED1, the knob S1 and the negative line form a closed loop, and the indicator light LED1 is lit; if the Harding plug (under test) cannot be powered on normally, there is no electricity at the X1-1 terminal, and the indicator light LED1 is not lit, thereby realizing the monitoring of the Harding plug (under test).
[0031] The RIOM board is provided with a functional circuit, which includes a central processing unit. The I / O interface of the central processing unit is led out through a wire or a printed line to form an external interface. The device is electrically connected to the external interface. When the XI-1 terminal is powered on, the corresponding input interface of the RIOM board is connected to a high level. If the RIOM board can work normally (that is, the central processing unit can work normally), the corresponding output interface has an output which is fed back to the device through the external interface to turn on the controlled switch SB1. At this time, the lead-out terminal D, the controlled switch SB1, the indicator light LED2, the knob S1 and the negative line form a closed loop, and the indicator light LED1 is lit; if the RIOM board cannot work normally, there is no output, the controlled switch SB1 is in the disconnected state, and the indicator light LED2 is not lit, thereby realizing the monitoring of the RIOM board (under test).
[0032] Please refer to Figure 3 The indicator lights LED1 and LED2 of the device are configured to include multiple, and the number can be determined according to actual conditions and can match the number of interfaces of the RIOM board. When configured as multiple, the lead terminals A and D are electrically connected to the Harding plug (under test), and the lead terminal B is electrically connected to different interfaces of the RIOM board respectively to achieve synchronous monitoring of all interfaces.
[0033] Please refer to Figure 4 The device is also equipped with a current limiting resistor R to limit the current of the closed loop formed by the lead-out terminal A, the indicator light LED1, the knob S1 and the negative line, or the closed loop formed by the lead-out terminal D, the controlled switch SB1, the indicator light LED2, the knob S1 and the negative line, so as to meet the working requirements of the indicator light and prevent the indicator light from being burned out.
[0034] Please refer to Figure 5 , 6 , showing that the structure of the device includes Figure 1 , 2 On the basis of the structure shown, it also includes indicator light LED3, indicator light LED4 and knob S2. One end of indicator light LED3 is electrically connected to one end of indicator light LED1 that is divided into two paths, and the other end is electrically connected to end A of knob S2; end B of knob S2 serves as the lead-out terminal E of the device for connecting the negative line.
[0035] In such Figure 1 Based on the structure shown in FIG. 1 , one end of the indicator LED4 is electrically connected to one end of the lead-out terminal D of the indicator LED2 as the device, and the other end is electrically connected to the A end of the knob S2, as shown in FIG. Figure 5 As shown. Figure 2 Based on the structure shown in FIG. 1 , one end of the indicator LED4 is electrically connected to one end of the lead-out terminal D of the indicator LED2 as the device, and the other end is electrically connected to the A end of the knob S2. A controlled switch SB2 exists between the indicator LED4 and the A end of the knob S2. Figure 6 shown.
[0036] Indicator LED3 and LED4 are used to monitor the 110V of the RIOM board, and LED1 and LED2 are used to monitor the 24V of the RIOM board. The monitoring principle of LED1 and LED2 is as described above. Figure 5 The structure shown is used as an example for explanation.
[0037] When performing 24V monitoring, knob S2 is disconnected, knob S1 is turned on, and the power supply connected to the Harding plug (under test) is 24V; when performing 110V monitoring, knob S2 is turned on, knob S1 is disconnected, and the power supply connected to the Harding plug (under test) is 110V. The electrical connection relationship of this device is: the lead-out terminals A and D are electrically connected to the Harding plug (under test), and the lead-out terminal B is electrically connected to the RIOM board; if the Harding plug (under test) can be powered on normally, the terminals X1-1 and X1-2 are powered on, and at this time, the lead-out terminal A, the indicator LED1, the knob S2 and the negative line form a closed loop, and the indicator LED3 is lit; if the Harding plug (under test) cannot be powered on normally, there is no electricity at the terminals X1-1 and X1-2, and the indicator LED3 is not lit, thereby realizing the monitoring of the Harding plug (under test) providing 110V.
[0038] When the XI-1 and X1-2 terminals are powered on, the corresponding input interface of the RIOM board is connected to a high level. If the RIOM board can work normally, the corresponding output interface has an output which is fed back to the device through the external interface to turn on the controlled switch SB1. At this time, the lead-out terminal D, the controlled switch SB1, the indicator light LED4, the knob S2 and the negative line form a closed loop, and the indicator light LED4 is lit; if the RIOM board cannot work normally, there is no output, the controlled switch SB1 is in the disconnected state, and the indicator light LED4 is not lit, thereby realizing the monitoring of the 110V of the RIOM board (under test).
[0039] like Figure 6In the structure shown, the monitoring of the 110V Harding plug (under test) is as described above. When monitoring the 110V of the RIOM board (under test), if the RIOM board can work normally, the corresponding output interface has an output which is fed back to the device through the external interface to turn on the controlled switch SB2. At this time, the lead-out terminal D, the controlled switch SB2, the indicator light LED4, the knob S2 and the negative line form a closed loop, and the indicator light LED4 is lit; if the RIOM board cannot work normally, there is no output, the controlled switch SB2 is in the disconnected state, and the indicator light LED4 is not lit, thereby realizing the monitoring of the 110V of the RIOM board (under test).
[0040] In this device, the indicator lights LED1--LED4 can be configured as multiple, such as Figure 7 As shown. The number can be determined according to the actual situation and can match the number of interfaces of the RIOM board. When configured as multiple, the lead terminals A and D are electrically connected to the Harding plug (under test), and the lead terminal B is electrically connected to different interfaces of the RIOM board respectively to achieve synchronous monitoring of all interfaces.
[0041] This device configures indicator lights LED1 and 2 as a group to monitor the DC24V RIOM board, and configures indicator lights LED3 and 4 as a group to monitor the DC110V RIOM board. Indicator lights LED1 and 3 monitor the Harding plug (test), and indicator lights LED2 and 4 monitor the RIOM board. The type of monitoring being performed can be known by the lighting of the indicator lights, and the monitoring is intuitive.
[0042] Figure 7 The structure shown can also be configured with a current limiting resistor R, such as Figure 8 shown.
[0043] In order to facilitate the electrical connection with the Harding plug (under test) and the RIOM board, the device also includes a monitoring Harding plug electrically connected to the lead-out terminals A to E, including a male plug electrically connected to the lead-out terminals A, C, D, and E and a female plug electrically connected to the lead-out terminal B. When in use, the male plug of the monitoring Harding plug is plugged into the Harding plug (under test) to achieve electrical connection with the Harding plug (under test), and the female plug is electrically connected to each interface of the RIOM board.
[0044] The X1-1 and X1-2 terminals of the device can also be brought out through wires or through monitoring Harding plugs to provide signal simulation.
[0045] The negative line described in this article is a low power supply; the controlled switch is a relay, a thyristor, a transistor and other devices.

It must be pointed out that the disclosed embodiments do not limit the scope of the present disclosure. On the contrary, changes and modifications made without departing from the spirit and scope of the present disclosure are all within the scope of patent protection of the present disclosure.
