Speed limit board system and speed limit board management system

Abstract

The invention provides a speed limit board system. The speed limit board system comprises a control system which comprises a vehicle passing detection module, a control module and a speed limit display detection module; the speed limit display detection module is used for acquiring current first actual display speed information; the vehicle passing detection module is used for sending vehicle passing event information corresponding to a vehicle passing event when the vehicle passing event exists; the control module determines a speed limit value according to the vehicle passing event information in the vehicle passing event and preset construction plan mode information, inquires preset frame coding information corresponding to the speed limit value according to the speed limit value, and generates first direction control information according to the preset frame coding information and the first frame coding information; the display system comprises a motor, a first reel and a curtain; when the first direction control information is of a first type, the motor drives the first reel to roll, the first reel drives the curtain to roll in the first direction, and when the first direction control information is of a second type, the first reel drives the curtain to roll in the second direction.

Description

Technical field [0001] The present invention relates to the field of control, and more particularly to a speed limit cell system and a speed limit card management system. Background technique [0002] When the railway business line needs to use the mobile deceleration signal, the following referral call is required, and the restricted speed card is replaced during the construction process and after a period of time according to the relevant rules. Now there are several problems in the process of use: [0003] (1) Artificial replacement speed card, time-consuming labor, inconvenience, and low efficiency. At present, it is necessary to use a limited speed limit for a limited speed value. You need to prepare a number of different speed limits, for different construction work items, construction conditions, work methods and release train conditions, you need manual surveillance lines. The passage, at the specified time to the specified location, replace different limit speeds multipl...

AI Technical Summary

Problems solved by technology

[0004] (2) There is a lack of centralized management and supervision of speed limit plates, and the phenomenon of wrongly inserting speed limit plates occurs from time to time

At present, the management of information such as the location of the speed limit sign, speed limit level, and working status is still managed by decentralized multi-person management. If the speed limit is carried out at multiple points at the same time, there may be a situation where the speed limit of a certain line exceeds 3 places. , affecting the punctual operation of trains;

[0005] (3) If the speed limit sign tilts or falls when no one is on duty, if it cannot be found and corrected in time, it will cause hidden dangers to driving safety
