Railway construction safety protection system based on radio technology

Abstract

The invention provides a railway construction safety protection system based on a radio technology. The railway construction safety protection system is characterized by comprising a safe hand ring, a locomotive position transmitter and a safety officer supervision device; an MCU microprocessor main control chip of the safe hand ring is connected with a receiving module, a vibration motor capable of alarming through voice vibration, a display screen and an RF transmission chip; an MCU microprocessor main control chip of the locomotive position transmitter is connected with a GPS receiving module, the display screen and the RF transmission chip, and the RF transmission chip is connected with a radio frequency power amplification module; an MCU microprocessor of the safety officer supervision device is connected with the GPS receiving module, the display screen, the RF transmission chip, a key configuration input device, a vibration motor capable of prompting through voice vibration and a buzzer; or, the locomotive position transmitter is a tunnel operation transposer. Construction personnel wear the safe hand ring and directly receive signals sent by a locomotive, the intermediate links of signal transmission and processing are omitted, the response is rapid, and the safety of the construction personnel is ensured.

Description

technical field [0001] The invention relates to the field of railway construction safety protection, and is a railway construction safety protection system based on radio technology. Background technique [0002] The existing safety protection method for online construction of railway construction personnel is as follows: when the construction team works online, there will be 2-4 protectors responsible for safety protection according to the type of construction. A protector (in-station protector) checks the running status and location of online vehicles in the dispatching room of the station. When a vehicle approaches the construction work area, the station guard will notify the guard on the construction site through a dedicated telephone, and the guard will notify and direct the on-site construction workers to evacuate the railway line to ensure the safety of the construction workers. However, from the actual situation, with the increase of railway speed, the negligence of...

AI Technical Summary

Problems solved by technology

However, from the actual situation, with the increase of railway speed, the negligence of the guards, the overconfidence of the construction personnel and other factors, the accidents of construction personnel's personal injury and death occur frequently. From this, it can be found that the existing safety protection measures are wasteful. Manpower cannot guarantee the safety of construction workers to the greatest extent

Chinese Invention Patent Publication No.: CN104691582A, which discloses a railway construction protection system and method based on smart bracelets. The 3G and Internet technologies used have the following deficiencies: 1. High manufacturing costs, complex systems, and poor reliability

2. The use of 3G and Internet technology needs to be transmitted through the 3G network, and most of the construction work areas are field operations, and the 3G network coverage is unstable or even has no coverage

will make the system unusable

3. 3G technology cannot solve the problem of signal attenuation in tunnel operations

4. This technology adopts 3G wireless transceiver function, which needs to continuously transmit and receive signals to ensure normal operation. However, the small size of the bracelet cannot meet the installation of large-capacity batteries, so the battery life has become a major shortcoming that limits its use.

5. This technology adopts 3G base station positioning technology. This technology is very dependent on the base station. It cannot be located where there is no signal. In addition, the lack of positioning accuracy is also its biggest shortcoming.

6. The data transmission of this technology adopts 3G network upload and download, thus generating data traffic, which in turn increases the high operating cost
