Referring to fig. 1, the present invention provides a railway deceleration signal plate. The railway speed-reducing signal board is arranged near a railway business line construction site and used for displaying the limited running speed of a train running near the construction site and ensuring the safe running of the train. Of course, in other embodiments of the present invention, the railway deceleration sign can also be applied to other places where the speed limit needs to be adjusted, such as two sides of a highway, etc. The railway speed-reducing signal board can automatically adjust the limiting speed through the control component 100, effectively solves the problem of potential safety hazards caused by the fact that constructors need to replace the speed regularly at present, achieves automatic adjustment of the limiting speed, enables a train to control the running speed to be below the limiting speed, does not need the constructors to replace, reduces the potential safety hazards of the constructors, is simple to operate, is convenient for the constructors to use, and reduces subsequent processes.
In one embodiment, the railway deceleration sign includes a flip-flop display (not shown), a drive component (not shown), and a control component 100. The card-turning type display is used for displaying the limited speed when the train runs, and the limited speed displayed by the card-turning type display can be adjusted to display different limited speeds. Also, the speed limit of the flip display is realized by the cooperation of the driving part and the control part 100. The control part 100 sends out a control signal to control the movement of the driving part so that the driving part controls the card-flipping type display to adjust the limit speed.
Specifically, the card-turning type display comprises a display panel, an adjusting component and at least two replaceable digital cards, wherein the adjusting component is arranged in the display panel and is used for adjusting the digital cards so that the digital cards are positioned on the display panel and display the limited speed. The driving component is connected with the adjusting component and used for driving the adjusting component to move. The control component 100 is electrically connected with the driving component and is used for controlling the driving component to move, so that the driving component drives the digital card to move, and the display limiting speed of the display panel is adjusted.
The card-turning type display also comprises a display shell, the display panel is arranged on the display shell and forms a box body structure, and all parts of the card-turning type display are arranged in the display shell. Specifically, the adjusting component and at least two replaceable display boards are positioned in the display shell. In this way, the adjustment member may move the number plate within the display housing such that additional number plates may be moved to the display panel to replace the number plate at the display panel to display the correct limit speed.
Further, the display panel has a display window through which the number plate is exposed. Optionally, the display window is a hollow-out display window, and a transparent window, such as transparent glass or plastic, may also be provided. It is understood that the speed limit of the card-flipping display may be two or three digits, although more digits may be displayed. Illustratively, the flip-flop display of the present invention displays a two digit number.
The adjusting component comprises a gear, a digital card is arranged at the tooth part of the gear, and the other end of the digital card is suspended under the self gravity. Thus, a plurality of number cards can be arranged on one circle of tooth part of the gear. Therefore, when the gear rotates, the gear can drive the number plate to move, so that the corresponding number plate rotates to the display panel to display the speed limit. Optionally, the adjusting component further includes an elastic shifting piece, and the elastic shifting piece is disposed on the top of the display panel and disposed toward the display housing. The elastic shifting piece can clamp the next digital card. When the gear is driven, the number plate naturally falls over the elastic shifting piece, and the next number plate is blocked by the elastic shifting piece, so that the adjustment of the number plate is realized in a reciprocating way, and the adjustment of the speed limit is further realized. And when the card-turning type display displays two digits, the number of the adjusting parts is two, and the two adjusting parts can respectively drive the digital cards corresponding to the gears to move, so that the two digital cards of the display panel can display different numerical values.
The driving part is connected with the gear, when the speed limit needs to be adjusted, the control part 100 sends out a control signal, at the moment, the control part 100 controls the driving part to move according to the control signal, and then the driving part drives the adjusting part to move, so that the gear of the adjusting part can drive the digital card to move, and the corresponding speed limit is displayed. Optionally, the driving component is a stepping motor, and the stepping motor can move by a corresponding number of steps after receiving the control signal, so that the corresponding number plate can be moved to the display panel. At this time, the output shaft of the stepping motor can be directly installed on the gear to drive the gear to rotate. Of course, in other embodiments of the present invention, the driving member may also be another structure capable of driving the gear of the adjusting member to rotate. The control signal can be a pulse signal, a motion displacement signal, a rotation number signal and the like, as long as the drive component can be controlled to move.
When the speed limiting is adjusted by the railway deceleration signal board in the embodiment, the control part 100 receives the control signal and then can control the driving part to move, so that the driving part drives the adjusting part of the card-turning type display to move, and then the adjusting part can drive the digital board to move in the display panel, so that the digital board displayed by the display panel is replaced, and the purpose of adjusting the speed limiting is achieved. Railway signal shows can drive the adjustment part motion through control unit 100 control drive part, the effectual potential safety hazard problem that needs constructor periodic replacement to lead to of solution, realize the automatically regulated and the remote control that the restriction speed shows, require train driver to control the operating speed below the restriction speed, need not the constructor scene and change the speed reduction signal tablet, constructor's potential safety hazard has been reduced, and, railway speed reduction signal tablet easy operation makes things convenient for the constructor to use, reduce subsequent handling.
Optionally, the control unit 100 integrates GPRS communication, GPS/beidou, integrated antenna and integrated industrial SIM card, and supports RTK high-precision positioning, using low-power-consumption internet of things technology, beidou, GPS positioning technology. Optionally, the railway deceleration signal board further comprises a lithium battery, and the lithium battery is electrically connected with the control component 100 and supplies power to the control component 100 to ensure that the control component 100 works normally. After adopting the lithium cell power supply, can reduce the size and the weight of railway speed reduction signal tablet on the one hand, can also satisfy the continuous work of job site 96 hours at least simultaneously, guarantee the performance of railway speed reduction signal tablet. Of course, in other embodiments of the present invention, the control unit 100 may be powered by other types of batteries or solar panels.
In one embodiment, the control component 100 includes a control module 120 and a processing module 110, the control module 120 is electrically connected to the driving component and the processing module 110, and the processing module 110 is configured to transmit a control signal to the control module 120, so that the control module 120 controls the driving component to move. When the speed limit needs to be adjusted, the processing module 110 sends a control signal to the control module 120, and the control module 120 controls the driving component to drive the adjusting component to move according to the control signal, so as to adjust the speed limit.
In an embodiment, the processing module 110 is connected to an external control device in a remote communication manner, or a target instruction for generating the control signal is pre-stored in the processing module 110. It is understood that the control signal received by the control module 120 may be remotely transmitted or may be automatically generated by the processing module 110. That is, the railway deceleration sign may be in a fully automatic mode or a semi-automatic mode. When the railway deceleration signal board can be in a fully automatic mode, the control signal received by the control module 120 is automatically generated by the processing module 110. When the railway slowdown signal plate can be in a semi-automatic mode, the control signal received by the control module 120 is transmitted remotely.
Specifically, when the railway deceleration signal plate is in the semi-automatic mode, the control component 100 is in communication connection with external control equipment through the processing module 110, at this time, external control setting can send out a control instruction, the processing module 110 receives a control signal for adjusting the limiting speed, and feeds the control signal back to the control module 120, so that the control module 120 controls the driving component to drive the adjusting component to move according to the control signal, and the limiting speed is adjusted. Optionally, the external control device may be an industrial personal computer, and may be a handheld device such as an APP of a mobile phone. Therefore, construction related personnel remotely adjust the speed-limiting speed of the railway signal deceleration signal board in real time according to the time and the speed-limiting speed specified by the operation revelation command through a mobile phone APP and the like.
When the railway deceleration signal board is in the full-automatic mode, the processing module 110 prestores a target instruction for generating the control signal. After the railway deceleration signal board is installed, the control unit 100 is powered on, at this time, the processing module 110 processes the target instruction to generate a control signal and feeds the control signal back to the control module 120, so that the control module 120 controls the driving unit to drive the adjusting unit to move according to the control signal to adjust the limiting speed.
Further, the processing module 110 may process the target instruction, and generate the target instruction into a preset time interval. After a preset time interval, the processing module 110 generates a control signal and feeds the control signal back to the control module 120, so that the control module 120 controls the driving part to drive the adjusting part to move according to the control signal to adjust the limiting speed.
It can be understood that after the construction of the railway business line is completed, such as breaking the bottom and cleaning the screen, replacing the sleeper, replacing the switch and other work construction operations, a deceleration signal sign needs to be placed near the construction site after the line is opened, and generally, speed limits need to be set at intervals of several time periods, for example, the first limited speed is generally 35km/h, the next limited speed is generally 45km/h, the next limited speed is generally 60km/h, and then the normal operation is recovered. Of course, in other embodiments of the present invention, the speed limit for each time period is not limited to the above, and a speed limit for a plurality of time periods may be provided.
In this way, the processing module 110 generates the preset time interval according to the signals such as the number of the time periods required to be set, the length of the time periods, and the like. After the preset time interval is generated, and after the time length of the preset time interval passes, the processor generates a control signal for controlling the adjustment of the digital card, and feeds the control signal back to the control module 120, so that the control module 120 controls the driving part to drive the adjusting part to move according to the control signal, so as to adjust the limiting speed.
In an embodiment, the processing module 110 may generate at least two preset time intervals according to the target instruction, and each preset time interval is different. It should be noted that the processing module 110 directly generates the number of the required time periods and the preset time interval according to the target instruction. For example, two time periods are generated, a first preset time interval and a second preset time interval, and the time length of the first preset time interval is smaller than the time length of the second preset time interval. When the first preset time interval passes, the processing module 110 sends a first control signal, and at this time, the control module 120 controls the adjusting part to rotate to a preset distance according to the first control signal, and the display panel displays a limit speed. When the second preset time interval passes, the processing module 110 sends a second control signal, and at this time, the control module 120 controls the adjusting part to rotate to a preset distance according to the second control signal, and the display panel displays another limiting speed. Of course, in other embodiments of the present invention, the number of the time periods generated by the processing module 110 may also be three, four or even more, and the principle of the generation is substantially the same as that of the generation of two time periods, which is not repeated herein.
In an embodiment, the control component 100 further includes a time module 130, the time module 130 is electrically connected to the processing module 110, the time module 130 is configured to obtain a current time and feed back the current time to the processing module 110, and the processing module 110 generates a control signal according to the current time. The time module 130 can accurately obtain the time of the current location, and then judge the current limit speed according to the time, so as to ensure that the time length of each preset time interval is accurate, avoid deviation, and further ensure the safe operation of the train.
The time module 130 obtains the current time in real time and feeds the current time back to the processor, and when the time fed back by the time module 130 reaches a preset time interval, the processor generates a control signal and feeds the control signal back to the control module 120, so that the control module 120 controls the driving part to drive the adjusting part to move according to the control signal to adjust the limiting speed. Illustratively, the time module 130 feeds back time information obtained by the GPS and the beidou to the processor, so that the processor automatically determines the current speed limit speed according to the current time information, and if the speed limit needs to be changed, the current speed limit speed is automatically changed.
In one embodiment, the display panel is affixed with a reflective film for enabling the digital card to be viewed at night. The reflective film is attached to the surface of the display panel, so that the reflective film can prevent the digital board from reflecting light, the display effect is ensured, and a driver of the train can clearly see the display speed limit of the digital board. In addition, at night, due to the action of the reflective film, a driver of the train can clearly see the limited speed displayed by the display panel, and the display panel is suitable for being used at night. Optionally, the number plate displays black-on-yellow to meet the speed-limiting display requirements.
Referring to fig. 1 and 2, the present invention further provides a control method of a railway deceleration signal, which is applied to the railway deceleration signal of any of the above embodiments, the control method comprising the steps of:
s100: acquiring a control signal and feeding back the control signal to the control module 120;
s200: the control module 120 controls the driving part to move according to the control signal, so that the driving part drives the card-flipping type display to change numbers, thereby adjusting the limiting speed displayed by the display panel.
The control method of the railway deceleration signal board adopts the control signal to control the tile-turning type display to adjust the limiting speed. Specifically, the control module 120 may receive a corresponding control signal and control the driving component to move according to the control signal. Therefore, the driving part can drive the adjusting part to move when moving, so that the gear of the adjusting part can drive the number plate to move to display the corresponding speed limit.
When the control method of the embodiment is adopted to adjust the limiting speed, the control part 100 can control the driving part to drive the adjusting part to move, the problem of potential safety hazards caused by the fact that constructors need to replace the limiting speed regularly at present is effectively solved, automatic adjustment and remote control of limiting speed display are achieved, a train driver is required to control the running speed to be below the limiting speed, the constructors do not need to replace the speed reduction signal boards on site, and the potential safety hazards of the constructors are reduced.
In one embodiment, the acquiring the control signal includes the following steps:
the control signal is transmitted to the control module 120 by remote; or
The processing module 110 stores a target instruction, generates the control signal according to the target instruction, and feeds back the control signal to the control module 120.
It is understood that the control signal received by the control module 120 may be remotely transmitted or may be automatically generated by the processing module 110. That is, the railway deceleration sign may be in a fully automatic mode or a semi-automatic mode. When the railway deceleration signal board can be in a fully automatic mode, the control signal received by the control module 120 is automatically generated by the processing module 110. When the railway slowdown signal plate can be in a semi-automatic mode, the control signal received by the control module 120 is transmitted remotely.
Specifically, when the railway deceleration signal plate is in the semi-automatic mode, the control component 100 is in communication connection with external control equipment through the processing module 110, at this time, external control setting can send out a control instruction, the processing module 110 receives a control signal for adjusting the limiting speed, and feeds the control signal back to the control module 120, so that the control module 120 controls the driving component to drive the adjusting component to move according to the control signal, and the limiting speed is adjusted. Optionally, the external control device may be an industrial personal computer, and may be a handheld device such as an APP of a mobile phone. Therefore, construction related personnel remotely adjust the speed-limiting speed of the railway signal deceleration signal board in real time according to the time and the speed-limiting speed specified by the operation revelation command through a mobile phone APP and the like.
When the railway deceleration signal board is in the full-automatic mode, the processing module 110 prestores a target instruction for generating the control signal. After the railway deceleration signal board is installed, the control unit 100 is powered on, at this time, the processing module 110 processes the target instruction to generate a control signal and feeds the control signal back to the control module 120, so that the control module 120 controls the driving unit to drive the adjusting unit to move according to the control signal to adjust the limiting speed.
Referring to fig. 1 and 3, in an embodiment, the storing a target instruction in the processing module 110 and generating the control signal according to the target instruction includes the following steps:
s210: storing the target instructions in the processing module 110 prior to installing the flip-flop display;
s220: the processing module 110 generates a preset time interval according to the target instruction;
s230: after the preset time interval, the processing module 110 generates the control signal and transmits the control signal to the control module 120, so that the control module 120 transmits the control signal.
The target instructions may be stored directly in the processing module 110 when the railway signal retarder is installed near a railway line of business. In this way, the processing module 110 generates the preset time interval according to the signals such as the number of the time periods required to be set, the length of the time periods, and the like. After the preset time interval is generated, and after the time length of the preset time interval passes, the processor generates a control signal for controlling the adjustment of the digital card, and feeds the control signal back to the control module 120, so that the control module 120 controls the driving part to drive the adjusting part to move according to the control signal, so as to adjust the limiting speed.
In an embodiment, the processing module 110 may generate at least two preset time intervals according to the target instruction, and each of the preset time intervals is different.
It should be noted that the processing module 110 directly generates the number of the required time periods and the preset time interval according to the target instruction. For example, two time periods are generated, a first preset time interval and a second preset time interval, and the time length of the first preset time interval is smaller than the time length of the second preset time interval. When the first preset time interval passes, the processing module 110 sends a first control signal, and at this time, the control module 120 controls the adjusting part to rotate to a preset distance according to the first control signal, and the display panel displays a limit speed. When the second preset time interval passes, the processing module 110 sends a second control signal, and at this time, the control module 120 controls the adjusting part to rotate to a preset distance according to the second control signal, and the display panel displays another limiting speed. Of course, in other embodiments of the present invention, the number of the time periods generated by the processing module 110 may also be three, four or even more, and the principle of the generation is substantially the same as that of the generation of two time periods, which is not repeated herein.
Referring to fig. 1 and 4, in an embodiment, after the preset time interval elapses, the processing module 110 generates the control signal, including the following steps:
