Multi-channel intelligent anti-slip system, data communication method and communication data frame format

Abstract

The invention discloses a multichannel intelligent anti-slip system. The multichannel intelligent anti-slip system is characterized in that the multichannel intelligent anti-slip system comprises a plurality of intelligent metal shoes, a wireless transmission unit and an intelligent metal shoe state monitoring upper computer, wherein the wireless transmission unit is composed of a plurality of repeaters and a coordinator, the intelligent metal shoes comprise traditional metal shoe bodies, and intelligent boxes inside the traditional metal shoe bodies, the wireless transmission unit takes the coordinator as a network center, and a multilevel tree network is built by the coordinator and the multiple repeaters; and the multiple intelligent metal shoes are in multichannel communication with the wireless transmission unit constituted by the multiple repeaters and the network coordinator, and data are reliably sent to the intelligent metal shoe state monitoring upper computer in time. The intelligent metal shoe data are divided into business data and heartbeat data and transmitted in a multichannel mode, and the coordinator can obtain intelligent metal shoe business data at the highest speed; and increasing and updating of the number of the intelligent metal shoe or the number of the repeaters of the anti-slip system are convenient, the safety of a station yard is greatly improved, and the management pressure of station yard personnel is reduced.

Description

technical field [0001] The invention relates to the field of railway safety, and is especially suitable for realizing real-time monitoring and networking communication of the anti-slip state of railway intelligent iron shoes, and specifically relates to a multi-channel intelligent anti-slip system, a data communication method and a communication data frame format . Background technique [0002] With the increase of railway lines and wider coverage areas, the application of anti-slip iron shoes is becoming more and more extensive, and anti-slip iron shoes have become an important equipment for protecting the safety of personnel and vehicles. [0003] The traditional anti-slip device has the following problems: it is difficult to monitor whether the anti-slip device is placed in place; it is also difficult to monitor whether the anti-slip device has been taken out when the car starts; the anti-slip device cannot be reported in time if the anti-slip device is stolen; Back and ...

Problems solved by technology

[0003] The traditional anti-slip device has the following problems: it is difficult to monitor whether the anti-slip device is placed in place; it is also difficult to monitor whether the anti-slip device has been taken out when the car starts; the anti-slip device cannot be reported in time if the anti-slip device is stolen; Back and forth are all completed by manual operation, and the on-duty staff cannot promptly determine whether the anti-slip device is in a standardized and safe state

In the intelligent anti-slip system, there are often situations where multiple smart iron shoes request to send data at the same time, send repeated data multiple times, and a repeater has no signal, etc., resulting in signal conflicts, data packet loss, and important data cannot be transmitted in time. Reliability and speed are extremely poor
