Description

Technical Field

[0001] This invention relates to the field of rail transit signal control, and in particular to a fully automatic unmanned driver's cab linkage control method and equipment. Background Technology

[0002] In rail transit operations, fully automated driverless systems are gradually becoming more common. For fully automated lines that have been put into operation, personnel with driving skills should be on duty during the initial operation period to monitor the train's operating status throughout the journey and handle any train malfunctions or abnormalities promptly according to regulations. Therefore, for fully automated lines, it will be necessary to have personnel with driving skills on duty on the trains for an extended period of time.

[0003] In fully automated subway operation systems, there are currently two main ways to handle the situation when the driver's cab cover is opened. One is to issue an alarm and push video images at the ATS (Automatic Train Supervision) workstation, without triggering emergency braking; the other is to issue an alarm and push video images at the ATS workstation, triggering emergency braking. Because the current system or architecture cannot distinguish between whether the driver's cab cover was opened normally or abnormally by a passenger, only one approach can be chosen. If the first approach is used without triggering emergency braking, and the driver's cab cover is opened abnormally while operation continues, passengers may operate the driver's cab equipment improperly, potentially leading to an accident. If the second approach triggers emergency braking, and the driver or staff open the cover, emergency braking will disrupt operations, affect passengers, and cause complaints and dissatisfaction.

[0004] Whether the driver's dashboard cover is opened normally or abnormally by a passenger results in completely different outcomes or subsequent responses. An abnormally opened driver's dashboard cover requires emergency braking; a normally opened driver's dashboard cover does not require emergency braking. Under the current system architecture, it is impossible to distinguish between normal and abnormal opening of the driver's dashboard cover, and there is no better solution.

[0005] How to identify and control the opening mode of the driver's cab cover in a fully automated driverless vehicle has become a technical problem that needs to be solved. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects of the prior art and provide a fully automatic driver's cab linkage control device, method and equipment.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] According to one aspect of the present invention, a fully automatic unmanned driver's cab linkage control device is provided. The device includes a driver's cab, a driver's cab cover, a driver's cab cover lock, and a first limit switch. The device also includes a second limit switch. The second limit switch and the driver's cab cover lock are both disposed on both sides of the driver's cab. The driver's cab cover lock and the second limit switch are linked for control.

[0009] Preferably, the driver's cab cover lock and the limit switch are controlled independently.

[0010] According to another aspect of the present invention, a fully automated driverless cab linkage control method is provided, the method comprising the following steps:

[0011] Step S1: Determine whether the driver's cab cover is open. If no, end; if yes, proceed to step S2.

[0012] Step S2: Determine if the driver's cab cover opens normally. If it does, proceed to step S3; otherwise, proceed to steps S4 and S5 simultaneously.

[0013] Step S3: The vehicle transmits the message that the driver's cab cover is open normally to the signal vehicle equipment. The signal vehicle equipment sends the message that the driver's cab cover is open normally to the signal trackside ATS. The signal trackside ATS sends the received message to the train dispatch ATS workstation. The train dispatch ATS workstation displays the driver's cab cover open normally event and the process ends.

[0014] Step S4: The vehicle transmits a message that the driver's cab cover was opened abnormally to the video monitoring system. After receiving the message, the video monitoring system automatically activates the camera to point at the opened driver's cab, and the process ends.

[0015] Step S5: The vehicle transmits a message that the driver's cab cover has been opened abnormally to the on-board signal equipment, and simultaneously executes steps S6 and S7.

[0016] Step S6: The onboard signal equipment sends a message about the abnormal opening of the driver's cab cover to the trackside ATS. The trackside ATS then sends the received message to the dispatch ATS workstation. The dispatch ATS workstation displays the abnormal opening event of the driver's cab cover and the process ends.

[0017] Step S7: The on-board signal equipment outputs an emergency braking command to the vehicle, and the process ends.

[0018] Preferably, in step S1, the condition for determining that the driver's cab cover is open is that both limit switch one and limit switch two are in the closed state.

[0019] Preferably, in step S2, the condition for determining that the driver's cab cover is opened normally is that both limit switch one and limit switch two are in the off state.

[0020] Preferably, in step S2, the condition for determining that the driver's cab cover is not open is that limit switch one is in the open state and limit switch two is in the closed state.

[0021] Preferably, the transmission method to the signal vehicle equipment includes a hard-wired connection method and a network transmission method for the train control and management system.

[0022] Preferably, the vehicle transmits the message that the driver's cab cover has been opened abnormally to the video monitoring system, which is achieved through network transmission of the train control and management system.

[0023] According to a third aspect of the present invention, an electronic device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the program to implement the method described thereon.

[0024] According to a fourth aspect of the present invention, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method described thereon.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. This invention can automatically and correctly distinguish whether the driver's cab cover is opened normally by staff with a key or illegally by passengers, and take corresponding measures for different methods to prevent passengers from illegally operating the driver's cab, reduce the possibility of accidents, and improve the safety of the system.

[0027] 2. This invention adds a hard-wired connection method, which can improve the efficiency of subway operation in handling emergency situations where the driver's cab cover is illegally opened, reduce the impact on operation, and improve system availability when the emergency braking of the train is output by abnormally opening the driver's cab cover.

[0028] 3. Without operator intervention, the system can automatically determine whether the driver's cab cover is opened normally or abnormally, which improves the automation level of the system, reduces the workload of operators, avoids errors caused by manual operation, and provides users with a better user experience.

[0029] 4. This invention adds more precise linkage response. When the driver's cab cover is opened normally with a key, the normal opening event of the driver's cab cover is only displayed on the ATS workstation, without emergency braking, so that passengers can experience a higher level of subway service.

[0030] 6. The implementation cost of this invention is relatively low, and the cost-performance ratio with user satisfaction is relatively high. Attached Figure Description

[0043] The technical solutions of the embodiments of the present 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 the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0044] This embodiment relates to a fully automatic driverless cab linkage control device, as shown in Figure 1, which is a three-view drawing of an existing fully automatic driverless cab device. The device includes a driver's cab, a driver's cab cover, and a pair of limit switches, wherein the pair of limit switches includes a first limit switch 3 and a second limit switch 4 as shown in Figures 1(a) to 1(c).

[0045] The device also includes a pair of driver's cab cover locks, as shown in Figures 1(a) to 1(c), namely the first driver's cab cover lock 1 and the second driver's cab cover lock 2, whose states are always consistent. The driver's cab cover locks are independent and not associated with limit switch one. Whether the driver's cab cover is opened normally or abnormally with a key, limit switch one will be in the open state; when the driver's cab cover is closed, limit switch one will be in the closed state; the state of the driver's cab cover (open or closed) is determined by the state of limit switch one (open or closed).

[0046] This invention improves upon existing fully automated driverless cab devices, as shown in Figures 2(a) to 2(c) in three views. A pair of limit switches (II) are added, comprising a first limit switch (II) 5 and a second limit switch (II) 6 as shown in Figures 2(a) to 2(c). The limit switches (II) are positioned on both sides of the driver's cab, and the cab cover lock is located at the same position as and linked to the limit switches (II).

[0047] When the driver's cab cover is opened normally using a key, both limit switches one and two are in the open state; when the driver's cab cover is opened abnormally, limit switch one is in the open state and limit switch two is in the closed state. When the driver's cab cover is closed, both limit switches one and two are in the closed state.

[0048] This embodiment also relates to a fully automated driverless cab linkage control method, such as... Figure 3 The diagram shown is a circuit diagram of an existing fully automated driverless vehicle. The states of the first limit switch 3 and the second limit switch 4 remain consistent. Figure 6 This is a flowchart illustrating the information flow when the driver's cab cover is opened. When the driver's cab cover is opened, the message is transmitted via the Train Control and Management System (TCMS) to both the onboard signaling system and the Closed-Circuit Television (CCTV) system. The onboard signaling system sends the message to the trackside ATS, and the ATS workstation displays the message indicating that the driver's cab cover has been opened normally. Upon receiving the message, the CCTV system automatically activates the camera on the driver's cab to point at the opened cab.

[0049] like Figure 4 and Figure 5 This invention distinguishes between normal and abnormal opening of the driver's cab cover by adding a second limit switch and linking it to the driver's cab cover lock. The states of the first limit switch (5) and the second limit switch (6) remain consistent. On one hand, the status of the two pairs of limit switches (limit switch one and limit switch two) is collected by the Train Control and Management System (TCMS), then transmitted to the onboard signaling system via network and to the Closed-Circuit Television (CCTV) system via integrated monitoring. On the other hand, the status of the two limit switches is output to the onboard signaling system via hardwire. Information indicating abnormal opening of the driver's cab cover obtained through TCMS or hardwire is ORed; that is, if any one method indicates abnormal opening of the driver's cab cover, then it is considered abnormally opened, thus improving the system's safety and availability.

[0050] The fully automatic driverless cab linkage control method in this invention is as follows: Figure 7 As shown, it includes the following steps:

[0051] Step S1: Determine whether the driver's cab cover is open. If no, end; if yes, proceed to step S2.

[0052] Step S2: Determine if the driver's cab cover opens normally. If it does, proceed to step S3; otherwise, proceed to steps S4 and S5.

[0053] Step S3: The message that the vehicle has opened the driver's cab cover normally is transmitted to the signal onboard equipment through the train control and management system or hard-wired connection. The signal onboard equipment sends the message that the driver's cab cover has opened normally to the signal trackside ATS. The signal trackside ATS sends the received message to the train dispatch ATS workstation. The train dispatch ATS workstation displays the driver's cab cover opening normally event and ends.

[0054] Step S4: The message that the vehicle has abnormally opened the driver's cab cover is transmitted to the video monitoring system through the train control and management system network. After receiving the message, the video monitoring system automatically activates the camera to point at the opened driver's cab, and the process ends.

[0055] In step S5, the vehicle transmits the message that the driver's cab cover was opened abnormally to the signal onboard equipment through the train control and management system network or hardwire connection, and simultaneously executes steps S6 and S7.

[0056] Step S6: The onboard signal equipment sends the message of abnormal opening of the driver's cab cover to the trackside ATS via the train control and management system network or hardwire connection. The trackside ATS sends the received message to the train dispatch ATS workstation. The train dispatch ATS workstation displays the abnormal opening event of the driver's cab cover and ends.

[0057] Step S7: The on-board signal equipment outputs an emergency braking command to the vehicle, and the process ends.
