Problems solved by technology

[0007] 1. For nodes with relatively hidden locations, there is a problem that it cannot be tested
[0008] 2. For some cases, multiple tests are required, and each test needs to be checked node by node, which is very time-consuming
[0009] 3. In some cases, the failure cannot be reproduced using manual testing
For example, if the door open button is not pressed in place, the door will open, but the button information will not be collected; when the button is fully pressed, the button press information can be collected
When manually testing, it is impossible to reproduce the situation that the button is not pressed in place for a long time
[0010] 4. The labor cost is very high, and the single-person test cannot be completed, which consumes a lot of manpower
[0013] The disadvantage of this method is that it is necessary to purchase existing products, redesign the interface that matches the vehicle, modify or customize products
In view of the complexity of the interface, this method is not used at present

Embodiment 1

[0052] like figure 2 As shown, this embodiment describes a semi-automatic switching value fault detection method used in rail traffic control systems. The fault detection method includes detection of the input switching value. (up or down) will change accordingly, and the on-board system and the vehicle obtain the corresponding relay status information through the collector at the same time. The reaction of the vehicle can be quickly seen by the human eye, and whether the on-board system collects this state can be seen through the switch detection module connected to the on-board system.

[0053] Specifically, the detection of the input switching value includes the following steps:

[0054] S1a: Manually operate the vehicle to input the switch signal;

[0055] S2a: Collect the status information of the corresponding relay when the signal is input, and observe the vehicle's response when the signal is input at the same time;

[0056] S3a: input the collected corresponding r...

Embodiment 2

[0070] like Figure 4 and Figure 5 As shown, this embodiment records a fault detection system that implements the fault detection method described in Embodiment 1, including:

[0071] The collector is used to collect the state information of the corresponding relay;

[0072] The vehicle-mounted system is used to output the switching value signal, input and record the corresponding relay state information collected by the collector, and transmit the recorded corresponding relay state information to the switching value detection module;

[0073] The switching value detection module is used for analyzing the corresponding relay state information sent by the vehicle system and displaying the analysis result in real time.

[0074] The vehicle system includes:

[0075] The vehicle-mounted system input board is used to receive the corresponding relay status information input by the collector and input it to the vehicle-mounted system main board;

[0076] The vehicle-mounted syst...

Embodiment 3

[0082] In this embodiment, the vehicle-mounted door opening and closing button is taken as an example to illustrate the specific implementation of the detection method.

[0083] During on-site testing or official operation, a common failure is that when the driver presses the door open button, the door does not open, but the on-board system performs a follow-up operation to open the door, that is, the screen door is opened; or the door is opened, but the on-board system No follow-up was performed and the screen door was not opened. For the switch value fault, use this method to locate the fault.

[0084] The switching value of the door opening and closing button belongs to the input switching value, and the implementation steps of its fault detection method are as follows:

[0085] 1. Connect the switching value detection module (such as a notebook running the switching value detection software) to the output serial port of the on-board system recording board through the seri...

Abstract

The invention discloses a semi-automatic switching value fault detection method and system used for a rail traffic control system. The semi-automatic switching value fault detection method comprises the following steps: inputting a switching value signal; collecting the state information of a corresponding relay when the signal is inputted, and observing the reaction of a vehicle by manual operation; inputting the collected state information of the corresponding relay; recoding the state information of the corresponding relay; analyzing the state information of the corresponding relay; and displaying an analyzing result in real time. The semi-automatic switching value fault detection method further comprises the following steps: outputting the switching value signal; collecting the state information of the corresponding relay when the signal is outputted, and observing the reaction of the vehicle by manual operation when the signal is outputted; feeding back the state information of the corresponding relay; recoding the fed-back state information of the corresponding relay; analyzing the state information of the corresponding relay; and displaying the analyzing result in real time. The semi-automatic switching value fault detection system comprises a collector, a vehicle-mounted system and a switching value fault detection module. Due to the adoption of the semi-automatic switching value fault detection method and system, the problems can be found quickly, and the labor cost can be saved.

Description

technical field [0001] The invention relates to the technical field of fault detection, in particular to a semi-automatic switching value fault detection method and system for a rail transit control system. Background technique [0002] In the field of rail transit, there are many interfaces between the signaling system and the vehicle system, and the logic is complex, and most of the interfaces are switches. When there is a problem with these switches, it is difficult to locate the fault, which causes a big difference between the signal system provider and the vehicle side. In order to solve this difference, it is necessary to carry out switch fault detection. The relationship between the vehicle system and the signal system is as follows: figure 1 shown. [0003] At present, there are two methods for fault detection of switching quantity: one is manual detection, and the other is using special equipment. [0004] For method 1, since these switch interfaces are inside th...
