In a traditional outdoor equipment debugging mode, instruments such as a universal meter and a frequency shift meter are used for measuring and troubleshooting faults, circuit fault points are analyzed step by step, and finally fault processing is carried out. This way of debugging has the following disadvantages:
1. the problem is found to be lagging. The existing method can only find faults and deal with problems in the indoor and outdoor joint debugging joint test. Especially in the existing line transformation project, if the problems are found and treated within the time of the skylight points of the new and old systems which are connected reversely, the construction risk is greatly increased due to the limited time of the skylight points.
2. Lack of systematics. The traditional method adopts a mode of finding and solving problems, can not detect systematically, can only find the problems little by little in debugging, and can not detect and analyze circuits such as a signal machine, a track circuit, turnout control and the like systematically.
3. There is a risk of missed inspection. From the opened line, even if the problems found in debugging are solved through the joint debugging of the system, the newly-invested signal system still exposes a lot of problems which are not found in the debugging process in the application process.
4. The construction efficiency is low. The existing outdoor fault testing and processing method is complicated, has high dependence on technical ability of technicians, has high requirements, and is not beneficial to efficient processing of field problems.

The test button device provides the operating buttons to simulate the positioning, reverse and four-opening states of the switch machine, an operator can manually operate the buttons to switch on or off a lighting circuit of the annunciator, and the analog annunciator is in a lighting or lighting-out state.
The controller analyzes signals to obtain simulation test parameters, and provides dynamic information (such as voltage and current) and related indicator lamp states (such as short circuit, open circuit, positive position, reverse position and quarto state) displayed by the touch display screen.
The controller can provide fault diagnosis information according to the collected monitoring and collecting information of the voltage and the current, and the fault self-diagnosis function of the signal equipment simulation testing device is achieved. The controller specifically selects an STM32 chip as a main control chip.
The simulation test device for the outdoor signal equipment has the following effects:
1. by adopting the technical scheme, the joint debugging test can be changed into unconstrained construction only after the outdoor equipment is installed in the original technical scheme, so that the constraint force between the working procedures is reduced, and the failure rate of the joint debugging joint test is reduced.
2. When the method is applied to the existing line construction project, simultaneous construction and detection are realized, the fault treatment is completed in advance, the construction task amount of opening the skylight of the new system is reduced, and the construction risk of reverse connection of the new system and the old system is greatly reduced.
3. And in the construction stage, the signaler, the turnout and the track circuit can be systematically debugged for many times, so that the failure and misjudgment risks are reduced.
The outdoor signal equipment simulation test device adopts an electronic circuit to simulate an electrical circuit, and realizes the functional equivalence of an indoor circuit. The simulation device can be used independently or in series and parallel connection to simulate different scenes. The liquid crystal display is adopted for displaying, and various simulation and monitoring information can be provided. In addition, the diagnostic test software built in the controller can be used for carrying out preliminary circuit fault self-diagnosis analysis.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
