In view of the above problems, the embodiment of the present invention provides a novel device for comprehensively alerting a dead man to activate a vehicle in an urban rail vehicle, which is a novel dead man switch (i.e. a switch that needs to be pressed by a driver all the time, once a cam switch on a driver is released, the vehicle can be immediately braked until the vehicle stops, and during the period, the driver has no way to reset, and pushes a handle of the driver to a brake position to reset and re-start) to activate a man button (i.e. a button triggered at regular time), wherein the implementation of the alerting function comprises a traction system, a train control system, a bidirectional cam switch of a handle of the driver, an event recorder, an alerting confirmation button, an audible and visual alarm prompt and a punishment brake relay, and on the basis of continuous and intermittent control, based on the cam switch state of the handle of the driver and the action state of the handle of the driver, the method is characterized in that a vigilance trigger period is set based on the speed of the train, corresponding vigilance is carried out through an entity vigilance confirmation button or a dynamic digital quantity and an analog quantity signal of a driver controller, and overtime micro action, namely, a punishment braking dynamic vigilance function is applied, so that unnecessary corresponding vigilance action of the driver is reduced as much as possible, the operation burden of the driver is lightened, a driving device of the driver is reflected more comprehensively and accurately, the workload of the driver is reduced to the greatest extent, and the safety of train driving is greatly improved.

In the embodiment of the invention, the cam switch is triggered in the handle of the driver controller, the handle of the driver controller keeps a certain position and does not change within a certain time, the event recorder triggers the sound-light alarm, and the alarm button is not triggered within a certain time, so that the vehicle is braked.

It should be noted that, in the embodiment of the present invention, the response condition not only has the alarm button, but also can respond to the alarm through the change of the handle position of the driver controller, so that the driver does not need to perform additional operation (for example, pressing the alarm button), and responds to the alarm through normal driving (moving the handle position of the driver controller), so as to avoid braking the vehicle.

Example 1

According to an aspect of an embodiment of the present invention, there is provided a rail train early warning apparatus, fig. 1 is a schematic view of the rail train early warning apparatus according to an embodiment of the present invention, and as shown in fig. 1, the rail train early warning apparatus may include: an event recorder 11 and a brake switch 13. The following describes the rail train warning device in detail.

And the event recorder 11 is used for triggering an alarm to give an alarm when the driver handle is detected to enter the preset position for more than a preset time, wherein the driver handle is switched to the preset position in response to a preset operation when the cam switch is activated.

Optionally, in the embodiment of the present invention, the event recorder may be configured to record the running information of the rail train (for example, the speed, acceleration, braking condition, running time, etc. of the rail train), and the triggering information of the rail train. That is, in the embodiment of the present invention, the handle position state of the driver controller, the cam switch, the alarm button, etc. may be monitored in real time according to the digital quantity and analog quantity signals of the vehicle input to the event recorder.

It should be noted that, in the embodiment of the present invention, the cam switch in the driver handle needs to be triggered first, that is, the driver handle can be actuated after the cam switch is activated.

Therefore, in the embodiment of the present invention, the driver grip can be switched to the predetermined position in response to the predetermined operation only when the cam switch is in the activated state. That is, after the cam switch is activated, the driver handle can act, and then the corresponding traction braking position can be pushed.

In addition, the event recorder triggers an alarm to give an alarm when it is determined that the handle of the driver is pushed to a preset position for a certain time (wherein the time is determined based on the speed of the rail train).

In addition, it should be noted that, in the embodiment of the present invention, the cam switch may be a bidirectional cam switch.

And the brake switch 13 is connected with a traction system of the target train and used for jumping to a disconnected state when the event recorder detects that the alarm button and the driver controller handle are not triggered in a preset period, wherein when the brake switch is in the disconnected state, the target train is triggered to enter a braking state through the traction system.

And the event recorder 11 is also used for controlling the alarm to release the alarm operation when detecting that the alarm button or the driver controller handle is triggered within a preset period.

Optionally, the alarm button may be a "live man button", that is, when pressed within a predetermined time, a rail train braking penalty is not triggered; otherwise, when the brake is not triggered within the preset time, the brake punishment of the rail train is triggered.

Therefore, in the embodiment of the present invention, the jumping of the brake switch to the off state may be accomplished under any of the following conditions: the event recorder detects that the alarm button is not triggered in a preset period, and the event recorder detects that the handle of the driver is continuously kept at a preset position.

In addition, when the brake switch is in an off state, the traction system of the rail train receives one of the hard line signals, and the hard line signal changes from a high level to a low level, so that the rail train is triggered to brake. Since low-level triggering of vehicle braking is a widely used fail-safe measure for rail trains, it is not described herein in detail.

As can be seen from the above, in the embodiment of the present invention, an event recorder may be utilized, and is configured to trigger an alarm to give an alarm when it is detected that the handle of the driver enters the predetermined position for more than a predetermined time period, where, in a state where the cam switch is activated, the handle of the driver is switched to the predetermined position in response to a predetermined operation; a brake switch connected with a traction system of the target train for jumping to a disconnected state under a predetermined condition, wherein the predetermined condition includes at least one of: the event recorder detects that the alarm button is not triggered in a preset period, the event recorder detects that the handle of the driver controller is continuously kept at a preset position, and when the brake switch is in an off state, the traction system triggers the target train to enter a braking state, so that the purpose of determining the on-off state of the brake switch of the train by controlling the on-off state of the brake switch according to the trigger state of the alarm button or the handle of the driver controller by using the event recorder is realized, and the technical effect of improving the safety of train driving is improved.

Therefore, the early warning device for the rail train provided by the embodiment of the invention solves the technical problem that in the related technology, a driver needs to perform alert confirmation by an extra response action unrelated to driving operation in the driving process of the vehicle, so that the workload of the driver is increased.

In an alternative embodiment, a cam switch is provided in the operator's handle, and the traction system relieves braking when the cam switch is activated.

In the embodiment, the dead man switch can be activated by activating the cam switch of the driver controller, and the traction system receives a signal that the braking signal is at a high level after the dead man switch is activated, so that the braking is relieved. Meanwhile, the event recorder takes the dead man activation signal as an enabling signal, and after the enabling signal exists, the event recorder starts to determine whether to trigger an alarm or not by judging the speed of the rail train and the position of a handle of a driver controller.

It can be known from the above that the cam switch can be arranged in the handle of the driver, here, a vigilance trigger cycle can be set based on the train speed according to the cam switch state and the action state of the handle of the driver, the vigilance is responded through a dead person vigilance confirmation button or a dynamic digital quantity and an analog quantity signal of the driver, and the dynamic vigilance function of punishment braking is exerted when the driver does not act overtime.

In addition, in the embodiment of the invention, a driver controller handle cam switch and an event recorder punishment brake relay normally-closed point are connected in the punishment brake train line, when a driver drives the vehicle to push the handle, the handle cam switch is activated, when the event recorder detects the action of the driver, the punishment brake relay does not act, the vehicle punishment brake train line is electrified, and the punishment brake is ineffective. On the contrary, when the driver looses the handle of the driver controller or does not act for a long time, the cam switch is disconnected or the punishment braking relay acts, the punishment braking train line is powered off, and the vehicle is punishment braked.

In an alternative embodiment, the alarm may comprise at least one of: light alarm, audible alarm.

Fig. 2 is a schematic view of an alternative rail train early warning apparatus according to an embodiment of the present invention, and as shown in fig. 2, the rail train early warning apparatus may include: a driver-controller bidirectional cam dead man switch (i.e., a cam switch), an alarm confirmation button (i.e., an alarm button), an event recorder, an optical alarm (i.e., an optical alarm), an audible alarm (i.e., an audible alarm), a penalty brake relay (i.e., a brake switch), a traction system, and a train system. Namely, in the embodiment of the invention, the implementation of the vigilance function is composed of a traction system, a train control system, a driver handle bidirectional cam switch, an event recorder, a vigilance confirmation button, an audible and visual alarm prompt and a punishment brake relay.

From the above, the early warning device for the rail train provided by the embodiment of the invention is redesigned aiming at the mode of triggering a dead man mechanism, the mode of monitoring the state of a living person and the response mode of the early warning, the new design scheme is a novel urban rail vehicle alarming function which fully utilizes the normal driving operation content of a driver, does not need additional operation, monitors the driving state of the driver comprehensively and accurately by monitoring digital quantity and analog quantity signals of the vehicle through an event recorder, and the driver can respond and confirm the early warning through the action of a traditional entity alarming confirmation button or a handle of a driver controller.

In summary, in the embodiment of the present invention, the implementation of the alert function of the early warning device of the rail train is composed of a traction system, a train control system, a bidirectional cam switch of a handle of a driver, an event recorder, an alert confirmation button, an audible and visual alert prompt, and a punishment brake relay, so that on the basis of a continuous and intermittent control, the alert trigger cycle can be set based on the train speed according to the state of the bidirectional cam switch of the handle of the driver and the state of the action of the handle of the driver, the alert can be responded through the dynamic digital quantity and analog quantity signals of the entity alert confirmation button or the driver, and the dynamic alert function of punishment brake can be applied when the train is not actuated after time out.

Example 2

According to an embodiment of the present invention, there is provided a method embodiment of a method for controlling a rail train early warning, it should be noted that, when the method is applied to any one of the rail train early warning devices described above, the steps shown in the flowchart of the figure may be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from the order shown.

Fig. 3 is a flowchart of an early warning control method for a rail train according to an embodiment of the present invention, and as shown in fig. 3, the early warning control method for a rail train includes the following steps:

and step S302, determining that the alarm of the target train is in an alarm state.

In this embodiment, the above-mentioned alarm may include, but is not limited to, the following: sound alarm, light alarm.

In an alternative embodiment, before determining that the alert button of the target train is in the alert state, the method of early warning control of the rail train may further include: determining that a cam switch is in an activated state, wherein the cam switch is arranged in a driver handle; and controlling the handle of the driver controller to switch the preset position in response to the preset operation acted on the handle of the driver controller.

For example, when it is determined that the cam switch is in the activated state, if a pushing operation acting on the driver handle is detected, the driver handle may be controlled to be switched to a predetermined position in response to the pushing operation.

Therefore, in the embodiment of the invention, after the cam switch of the driver controller is activated, namely the dead man switch is activated, the traction system receives a high-level braking signal, so that the vehicle braking is relieved, and a driver pushes the handle into the traction position to accelerate the traction of the vehicle. The event recorder starts to observe the position of the handle of the driver controller, and if the driver controller does not act within a certain time (the time is called detection time and is calculated according to the speed of the train), the event recorder sends out an alarm signal so as to trigger an alarm to give an alarm.

In an alternative embodiment, determining that the alarm of the target train is in an alarm state comprises: counting the accumulated time length of the handle of the driver controller in a preset position; and triggering an alarm of the target train to execute alarm operation under the condition that the accumulated time length exceeds the preset time length.

In this embodiment, when the handle of the driver controller is switched to the predetermined position while the cam switch is in the activated state, the alarm of the target train may be triggered to perform the alarm operation when it is determined that the accumulated time length of the handle of the driver controller at the predetermined position reaches the predetermined time length. For example, the event recorder may generate an alarm signal based on which an alarm is triggered, and an alarm button that is not triggered for a certain time may cause the vehicle to brake.

And step S304, detecting whether an alarm button or a driver controller handle on the target train is triggered or not to obtain a detection result.

And step S306, determining the trigger state of the alarm button or the driver controller handle in a preset detection period based on the detection result.

And step S308, determining the processing mode of a brake switch or an alarm of the target train based on the trigger state.

It should be noted that, in the embodiment of the present invention, the response after the alarm may be performed in two ways, one is performed by using the alarm button, and the other is performed by using the handle of the driver to change the position of the handle of the driver, that is, the driver is determined whether to be online by using the live switch. If the driver does not respond in any way within a certain time (the time is called response time and is a certain preset value), the event recorder triggers the relay to act, so that the dead man switch is disconnected to supply power to the braking train line, and the traction system receives a low-level signal of the braking train line to apply the brake.

At any time, if the driver releases the cam switch, the dead man switch can cause the power loss of the braking train line, and the traction system can further apply the brake. Once the brakes are applied, the driver will not be able to intervene until the vehicle stops reaching zero speed, at which point the driver can reset by pulling the handle back to the maximum braking position. Then the user pushes the traction position again, and the user can start again.

Therefore, in the embodiment of the invention, the alarm of the target train can be determined to be in the alarm state; then detecting whether an alarm button or a driver controller handle on the target train is triggered or not to obtain a detection result; determining the trigger state of an alarm button or a handle of a driver controller in a preset detection period based on the detection result; and the processing mode of the brake switch or the alarm of the target train is determined based on the trigger state, so that the purpose of determining the on-off state of the brake switch of the train by using the event recorder to control the on-off state of the brake switch according to the trigger state of the alarm button or the handle of the driver controller is realized, and the technical effect of improving the safety of train driving is improved.

Therefore, the early warning control method for the rail train provided by the embodiment of the invention solves the technical problem that in the related technology, a driver needs to perform the vigilance confirmation by an extra response action irrelevant to the driving operation in the driving process of the vehicle, so that the workload of the driver is increased.

In an optional embodiment, before determining the trigger state of the alarm button within the predetermined detection period based on the detection result, the method for early warning control of a rail train may further include: acquiring speed information of a target train; cycle information of a predetermined detection cycle is set based on the speed information.

In the embodiment of the invention, a dead man button which is continuously fed back and a live man button which is regularly fed back are integrated, the dead man button is integrated in a handle cam switch of a driver controller, the handle position state of the driver controller is monitored in real time according to vehicle digital quantity and analog quantity signals which are input into an event recorder, different alert detection times are set according to different speed grades, and the novel urban rail vehicle alert function of response confirmation is realized by integrating actions of an entity alert confirmation button and the handle of the driver controller.

In an alternative embodiment, the processing mode of determining the brake switch or the alarm of the target train based on the trigger state comprises the following steps: when the trigger state indicates that the alarm button and the handle of the driver controller are not triggered in a preset detection period, controlling the brake switch of the target train to jump to a disconnected state, wherein when the brake switch is in the disconnected state, the target train is triggered to enter the brake state through the traction system; and when the trigger state indicates that the alarm button or the driver controller handle is triggered within a preset detection period, controlling the alarm to release the alarm operation.

According to the embodiment of the invention, when the alarm button and the handle of the driver controller are not triggered within the preset time, the brake switch is switched to the off state, so that the traction system triggers the target train to enter the braking state.

Therefore, in the embodiment of the invention, the response condition not only has the alarm button, but also can respond to the alarm through the change of the handle position of the driver controller, so that the driver does not need to do additional operation (for example, pressing the alarm button), and the alarm is responded through normal driving (pushing the handle position of the driver controller), and the vehicle brake is avoided. Namely, in the embodiment of the invention, the change of the handle position of the driver controller and the alarm button can be combined to play the role of a live button so as to prove that a driver is in a normal state and ensure the running safety of a vehicle.

In summary, according to the early warning control method for the rail train provided by the embodiment of the invention, the warning trigger period is set based on the train speed according to the switching state of the bidirectional cam of the handle of the driver and the action state of the handle of the driver, the warning is responded through the entity warning confirmation button or the dynamic digital quantity and analog quantity signal of the driver, and the dynamic warning function of punishing braking is applied when the train is not operated overtime. In addition, in the embodiment of the invention, the unnecessary alert response action of the driver is reduced, the operation burden of the driver is lightened, the driving state of the driver is reflected more comprehensively and accurately, the workload of the driver is reduced to the maximum extent, and the safety of train driving is greatly improved based on the effective signal feedback of the driver in the normal driving state as much as possible.
