Definitions
- the present disclosure proposes a vehicle-mounted controller, which includes: an acquisition module for acquiring a parking threshold and accumulated ranging error; an indication module for obtaining a parking threshold and a cumulative ranging error; The cumulative ranging error indicates whether the train is open or not.
- the embodiments of the present disclosure propose a controller, including a memory, a processor, a receiver, a transmitter, and a computer program stored in the memory and running on the processor.
- the processor When the computer program is executed, the train door opening determination method described in the embodiment of the first aspect of the present disclosure is implemented.
- the present disclosure proposes a computer-readable storage medium that stores a computer program, which is characterized in that, when the computer program is executed by a processor, the method described in the first aspect of the present disclosure is implemented.
- the above-mentioned train door open judgment method when the computer program is executed by a processor, the method described in the first aspect of the present disclosure is implemented.
- the computer program stored thereon when executed by the processor, it prevents the train from opening the door in an unreasonable position, which may cause a safety accident.
- FIG. 3 is a schematic diagram of a vehicle-mounted controller provided by an embodiment of the present disclosure
- the method for determining train door opening includes the following steps:
- the parking threshold needs to be acquired first.
- the train When the train is running and stopping, the train arrives at a parking position according to the control parameters.
- This parking position is called the theoretical parking position. If the train reaches a parking position, and this parking position is the most accurate parking position, the parking position is called the precise parking position.
- the theoretical parking position when the train is stopped is difficult to reach the precise parking position of the train, that is, it has a certain error. When the error is small, the train can be instructed to open the door without affecting the safety of the vehicle and the safety of passengers. Therefore, the parking threshold needs to be obtained.
- the function of the parking threshold is to determine whether the distance between the theoretical parking position of the train and the precise parking position allows the train to open the door without affecting the safety of the vehicle and the safety of passengers.
- the parking threshold is a range value. When the parking position of the train is within the range of the parking threshold, it can be considered that the train is theoretically stopped. Therefore, obtaining the parking threshold can be used to indicate whether the train is theoretically stopped.
- this deviation value can be characterized by obtaining the accumulated ranging error.
- the cumulative ranging error is lower than a preset value, it means that the actual parking position of the train is not much different from the theoretical parking position of the train, and there is no failure similar to the loss of the route transponder; when the cumulative ranging error is higher than a preset value
- the value is set, it means that the actual parking position of the train differs greatly from the theoretical parking position of the train, and a fault similar to the loss of the incoming transponder occurs.
- the parking threshold and the cumulative ranging error can be used to indicate whether the train is open.
- the train can be instructed to open the door; if the train stops within the range of the parking threshold and the cumulative ranging error is greater than the preset value, no The train is allowed to open the door; if the train stops within the range of the stopping threshold, the train is not allowed to open the door.
- step S102 namely obtaining the accumulated ranging error, further includes the following steps:
- the train can enter and stop after passing through the inbound transponder. Therefore, the cumulative travel distance under normal circumstances is the distance between the inbound transponder and the stop position of the train. At this time, due to the inbound transponder distance The distance between train stops is very short, so the accumulated ranging error is small.
- the calculation of the cumulative ranging error is calculated by the cumulative travel distance, generally taking 2% of the cumulative travel distance for estimation. Therefore, the greater the accumulated travel distance, the greater the accumulated ranging error.
- the parking threshold includes the first parking threshold.
- step S103 that is, according to the parking threshold and the accumulated ranging error, indicating whether the train is open or not, it includes the following steps:
- the train When the train stops within the first stopping threshold and the accumulated ranging error is less than the preset value, the train is instructed to open the door automatically;
- the train When the train is stopped within the first stopping threshold and the accumulated ranging error is less than the preset value, it means that the actual parking position of the train has also been stopped. At this time, the train can be allowed to open the door automatically without the control of the console or dispatcher.
- the parking threshold further includes a second parking threshold.
- step S103 that is, indicating whether the train is open according to the parking threshold and the accumulated ranging error, the method further includes the following steps:
- the door permission signal can be output to allow the train to open the door.
- the train is allowed to open the door, it needs to be opened under the control of the console or dispatcher, and the door cannot be opened automatically.
- the train When the train is stopped within the first stopping threshold and the accumulated ranging error is greater than the preset value, it means that the actual parking position of the train is not stopped. At this time, the train is not allowed to open the door.
- both the first parking threshold and the second parking threshold can indicate the train to open the door, but the range of the first parking threshold is smaller than the second parking threshold, that is, the first parking threshold has higher requirements for train parking accuracy.
- a parking threshold is used to instruct the train to automatically open the door, while the second parking threshold cannot be used to instruct the train to automatically open the door.
- the second parking threshold can instruct the train to output a door permission signal to allow the door to be opened, but the door needs to be opened manually, for example, through the console or The dispatcher instructed to open the door.
- the value range of the first parking threshold is plus or minus 30 cm
- the value range of the second parking threshold is plus or minus 50 cm.
- FIG. 3 shows a vehicle-mounted controller 100 provided by an embodiment of the present disclosure.
- the acquiring module 10 acquires the first parking threshold, the second parking threshold, and the accumulated ranging error.
- the first parking threshold and the second parking threshold are a range value. When the parking position of the train stops within the range of the first parking threshold or the second parking threshold, it can be considered that the train is theoretically stopped.
- the accumulated distance measurement error can be obtained to determine whether the actual parking position of the train is properly stopped.
- the cumulative ranging error is lower than a preset value, it means that the actual parking position of the train is not much different from the theoretical parking position of the train, and there is no failure similar to the loss of the route transponder; when the cumulative ranging error is higher than or equal to one
- the preset value it means that there is a big difference between the actual parking position of the train and the theoretical parking position of the train, and a failure similar to the loss of the incoming transponder occurs.
- the indication module 20 is also used to:
- the train When the train stops within the first stopping threshold and the accumulated ranging error is less than the preset value, the train is instructed to open the door automatically;
- the train stops within the first parking threshold it means that the theoretical parking position of the train is stopped.
- the theoretical parking position of the following train is slightly different from the actual parking position of the train.
- the theoretical parking position of the train can be approximated as the train. The actual parking position will not affect the safety of trains and passengers.
- the indicator module 20 instructs the train to open the door automatically, without the control of the console or dispatcher. .
- the indicating module 20 does not allow the train to automatically open the door.
- the indication module 20 is also used to:
- the range of the second parking threshold is larger than the first parking threshold, which means that the parking accuracy within the required range of the second parking threshold is lower. Therefore, the stopping of the train within the first stopping threshold means that the train is stopping within the second stopping threshold, but the stopping of the train within the second stopping threshold does not necessarily mean that the train stopping within the first stopping threshold.
- a controller 200 which includes a receiver 11, a memory 12, a processor 13, a transmitter 14, and is stored in the memory 12 and can be stored in the processor.
- the processor 13 executes the computer program running on the computer program 13, the steps in the train door opening determination method in the above-mentioned embodiment are implemented.
- the controller of the embodiment of the present disclosure when the computer program stored thereon is executed by the processor, it is avoided that the train opens the door at an unreasonable position, which may cause a safety accident.
- the train door opening determination method and other components and operations of the on-board controller in the embodiments of the present disclosure are known to those of ordinary skill in the art, and will not be described in detail here.
- Non-volatile memory may include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), or flash memory.
- Volatile memory may include random access memory (RAM) or external cache memory.
- RAM is available in many forms, such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDRSDRAM), enhanced SDRAM (ESDRAM), synchronous chain Channel (Synchlink) DRAM (SLDRAM), memory bus (Rambus) direct RAM (RDRAM), direct memory bus dynamic RAM (DRDRAM), and memory bus dynamic RAM (RDRAM), etc.
