[0003] The broken filament of the signal machine light will bring many adverse effects to the safety and operation of rail transit. From the perspective of operation efficiency, after the signal machine fails, the maintenance personnel need to spend extra time to locate the indoor and outdoor faults, which prolongs the time for equipment maintenance and inspection, and thus may affect the normal operation plan of the train and further reduce the operation efficiency. From the safety perspective, the maintenance personnel may be affected by the efficiency of the rescue repair due to the inability to quickly locate the indoor and outdoor faults of the signal machine, and the risk of accidents caused by equipment failure is increased. For the train driver, the lack of necessary signal information may affect normal driving and may cause driving safety accidents in special circumstances. Therefore, it is necessary to locate and judge the indoor and outdoor fault points of the broken filament of the signal machine, and then take effective prevention and solution measures.

[0004] In the prior art, when determining the indoor and outdoor faults of the signal machine, the staff needs to measure the voltage value of the corresponding terminal at the indoor distribution panel (the interface connecting the indoor and outdoor equipment) of the signal machine using a multimeter, and then manually judge the fault point, which not only has poor timeliness, but also requires the on-site maintenance personnel to have certain knowledge reserves and equipment support, and under special conditions, there may be the risk of electric shock.

[0021] Figure 3 This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] To address the aforementioned problems in the prior art, this invention provides a method for determining indoor and outdoor faults in rail transit signal controllers. Figure 1 This is a flowchart illustrating the indoor and outdoor fault determination method for rail transit signal controllers provided by the present invention, as shown below. Figure 1 As shown, the method includes the following steps 110 to 120.

[0024] Step 110: For multiple rail transit signal controllers, obtain the desired lighting status, current lighting status, and voltage data for each light position in the rail transit signal controller.

[0025] Specifically, a rail transit signal controller includes multiple light positions, such as red, yellow, green, blue, white, red-yellow, and blue-white lights. The red-yellow light position controls both red and yellow lights simultaneously, and the blue-white light position controls both blue and white lights simultaneously. The desired lighting status can be obtained from the automatic train monitoring system, the current lighting status from the computer interlocking system, and voltage data from a voltage acquisition unit. It's easy to understand that all of this data comes from multiple rail transit signal controllers.

[0026] In one embodiment, acquiring the desired lighting status, current lighting status, and voltage data for each light position in the rail transit signal controller includes: The desired lighting status of each light position in the rail transit signal is obtained from the automatic train monitoring system; Obtain the current lighting status of each light position in the rail transit signal system from the computer interlocking system; Acquire the initial voltage data of all the aforementioned rail transit signals from the voltage acquisition unit; The voltage data of each light position in the rail transit signal is determined based on the initial voltage data and the on-site location information of the rail transit signal.

[0027] Specifically, the implementing entity of this invention can be connected to an automatic train monitoring system, a computer interlocking system, and a voltage acquisition unit to obtain relevant data from the rail transit signal. It can obtain the desired lighting status of each light position in the rail transit signal from the automatic train monitoring system; the desired lighting status represents the desired on / off state of the corresponding light position. It can also obtain the current lighting status of each light position in the rail transit signal from the computer interlocking system; the current lighting status represents the actual on / off state of the corresponding light position. Furthermore, it can obtain the initial voltage data of all rail transit signals from the voltage acquisition unit, and then determine the voltage data of each light position in the rail transit signal based on the initial voltage data and the current on-site location information of the rail transit signal.

[0028] In the above embodiments, obtaining the desired lighting state and the current lighting state can help determine whether the filament is broken, while voltage data can improve the accuracy of indoor and outdoor fault detection.

[0029] Step 120: For each light position in the rail transit signal, determine the indoor or outdoor fault type of the light position based on the expected lighting status, current lighting status, and voltage data corresponding to the light position.

[0030] Specifically, for each light position in a rail transit signal controller, the indoor or outdoor fault type of the light position can be determined based on the expected lighting status, current lighting status, and voltage data corresponding to that light position. It is easy to understand that the method of the present invention can perform fault detection for each light position separately.

[0031] In one embodiment, determining the indoor / outdoor fault type of the lamp position based on the desired lighting state, the current lighting state, and voltage data includes: If the desired lighting state and the current lighting state of the lamp position are inconsistent, the filament breakage alarm corresponding to the lamp position will be triggered. When the broken wire alarm is triggered at the lamp position, the indoor or outdoor fault type of the lamp position is determined based on the voltage data corresponding to the lamp position.

[0032] Specifically, for each light fixture, if the expected lighting state and the current lighting state of that light fixture are inconsistent, the corresponding wire breakage alarm will be triggered. For example, if the expected lighting state of the green light is "on", but the current lighting state is "off", then the green light's wire breakage alarm will be triggered.

[0033] Furthermore, if the lamp position triggers a broken wire alarm, the indoor or outdoor fault type of the lamp position is determined based on the voltage data corresponding to that lamp position.

[0034] In the above embodiments, the consistency between the desired lighting state and the current lighting state of the lamp position determines whether the lamp position has a broken filament, which improves the accuracy of fault detection. Furthermore, by analyzing the specific indoor and outdoor fault types through voltage data, the detection accuracy is improved, and the labor costs and the risk of electric shock from human operation are reduced.

[0035] In one embodiment, determining the indoor / outdoor fault type of the lamp position based on the voltage data corresponding to the lamp position includes: If the voltage data corresponding to the lamp position is within the first preset voltage range, the indoor / outdoor fault type of the lamp position is determined to be an outdoor circuit fault. If the voltage data corresponding to the lamp position is a first preset voltage value, the indoor / outdoor fault type of the lamp position is determined to be an indoor circuit fault.

[0036] Specifically, if the voltage data corresponding to the lamp position is within a first preset voltage range, the indoor / outdoor fault type of the lamp position is determined to be an outdoor circuit fault. If the voltage data corresponding to the lamp position is the first preset voltage value, the indoor / outdoor fault type of the lamp position is determined to be an indoor circuit fault. Both the first preset voltage range and the first preset voltage value can be preset as needed; for example, the first preset voltage range can be from 105 volts (V) to 110V, and the first preset voltage value can be 0V. This embodiment of the invention does not impose specific limitations here.

[0037] In the above embodiments, the specific indoor or outdoor fault type of the lamp position is determined by comparing the voltage data with a preset range or preset value, thereby improving the accuracy of indoor and outdoor fault judgment.

[0038] In one embodiment, when the light fixture consists of a red light and a yellow light, and both the red light and the yellow light are currently lit, determining the indoor / outdoor fault type of the light fixture based on the voltage data corresponding to the light fixture includes: If the voltage data corresponding to the red light and the yellow light are both within the first preset voltage range, the indoor and outdoor fault type of the light position is determined to be an outdoor circuit fault.

[0039] Specifically, when a light fixture is configured as red and yellow, and both the red and yellow lights are currently illuminated, a special method is used to determine the indoor / outdoor fault type of the light fixture. If the voltage data corresponding to both the red and yellow lights are within a first preset voltage range, the indoor / outdoor fault type for that light fixture is determined to be an outdoor circuit fault.

[0040] In the above embodiments, a special judgment method is used under special light positions, which further increases the accuracy of indoor and outdoor fault detection.

[0041] In one embodiment, when the light fixture consists of a red light and a yellow light, and both the red light and the yellow light are currently lit, determining the indoor / outdoor fault type of the light fixture based on the voltage data corresponding to the light fixture further includes: If the voltage data corresponding to the red light is within the first preset voltage range and the voltage data corresponding to the yellow light is within the second preset voltage range, then the indoor / outdoor fault type of the yellow light is determined to be an indoor circuit fault. If the voltage data corresponding to the red light is within the second preset voltage range and the voltage data corresponding to the yellow light is within the first preset voltage range, then the indoor / outdoor fault type of the red light is determined to be an indoor circuit fault.

[0042] Specifically, when the light fixture is a red and a yellow light, and both the red and yellow lights are currently lit, if the voltage data corresponding to the red light is within a first preset voltage range and the voltage data corresponding to the yellow light is within a second preset voltage range, the indoor / outdoor fault type of the yellow light is determined to be an indoor circuit fault. It should be noted that the second preset voltage range does not overlap with the first preset voltage range, and the second preset voltage range is also preset as needed; for example, the second preset voltage range could be "voltage less than 5V." This embodiment of the invention does not impose specific limitations here.

[0043] If the voltage data corresponding to the red light is within the second preset voltage range and the voltage data corresponding to the yellow light is within the first preset voltage range, then the indoor / outdoor fault type of the red light is determined to be an indoor circuit fault.

[0044] In the above embodiments, when the light position is red or yellow, the different preset voltage ranges of the voltage data can accurately determine whether the red or yellow light is an indoor circuit fault or an outdoor circuit fault, avoiding the need for manual blind searching for fault locations, thereby improving equipment maintenance efficiency and reducing interference with the normal operation of the train.

[0045] The present invention provides a method for determining indoor and outdoor faults in rail transit signal controllers. For multiple rail transit signal controllers, it acquires the desired lighting status, current lighting status, and voltage data for each light position. For each light position, it determines the indoor or outdoor fault type based on the desired lighting status, current lighting status, and voltage data. This invention determines the indoor or outdoor fault type for each light position in a rail transit signal controller by using the desired lighting status, current lighting status, and voltage status, eliminating the need for manual measurement and judgment. This improves detection timeliness and accuracy, and reduces labor costs and the risk of electric shock from manual operation.

If the voltage data corresponding to the red light is within the second preset voltage range and the voltage data corresponding to the yellow light is within the first preset voltage range, then the indoor / outdoor fault type of the red light is determined to be an indoor circuit fault.
