Intelligent wheel stopper system based on wireless communication

Abstract

The invention discloses an intelligent wheel stopper system based on wireless communication, which comprises an intelligent wheel stopper monitoring instrument, a wireless communication network, an Internet network, a databank server and a remote monitoring center. The intelligent wheel stopper monitoring instrument, served as an instrument for acquiring, processing and transmitting field data, comprises a displacement sensor, a balance tilt angle sensor, a pressure sensor, a shaping circuit, an embedded type microprocessor and a serial port communication module, a wireless communication module, a real-time clock unit, a watchdog unit, a keyboard input unit, an LCD display unit, a power supply module unit, an EEPROM unit and an alarm unit. The intelligent wheel stopper monitoring instrument carries out collection treatment on field data which is sent out by the wireless communication module. The remote monitoring center receives information sent by the wireless communication module, manages and records working state information of the intelligent wheel stopper monitoring instrument and simultaneously sends a control command and data to the intelligent wheel stopper monitoring instrument through the wireless communication module. The intelligent wheel stopper monitoring instrument is connected with the remote monitoring center through the wireless communication network and the Internet network. The intelligent wheel stopper monitoring instrument is accessed into the wireless communication network through the wireless communication module. The remote monitoring center is connected with the Internet network through the databank server and completes communication with the wireless communication network through a gateway.

Description

technical field [0001] The present invention relates to a wheel stop for railway train vehicles. Background technique [0002] At present, the monitoring of the working status of the wheel stopper and the parking situation of the train in China is mainly carried out by manual regular inspection. While the railway transportation is developing towards large-scale, high-speed and automation, the wheel stopper used for parking brake in the train parking lot is particularly important. In some train depots with a long history of use, due to the early construction time and outdated equipment, the upper-level unit lacks real-time monitoring means for the working status of the wheel stoppers in each depot, which is not conducive to production management. At the same time, train parking lots are mostly located in remote areas, and parking brake failures often occur at night due to man-made damage. If they are not found and dealt with in time, not only equipment loss will be caused, b...

In some train parking lots with a long history of use, due to the early construction time and the outdated equipment on the site, the upper-level unit lacks real-time monitoring means for the working status of the wheel stoppers in each parking lot, which is not conducive to production management

At the same time, the train parking lots are mostly located in remote areas, and the failure of the parking brake due to man-made damage at night often occurs. If it is not found and dealt with in time, it will not only cause equipment loss, but may even cause a crash.

However, the method of manual periodic inspection has many shortcomings in the specific implementation, such as large errors, long monitoring cycle, and untimely abnormal handling, and cannot meet the requirements of railway automation and information development in terms of technology and economy.
