EMU wireless monitoring system based on GPRS
With the increase of train running speed, it is of great significance to implement train monitoring. The use of computer communication technology and GPRS technology (general wireless packet service) to realize the system monitoring of trains is mainly for online detection of factors affecting driving safety, centralized display, storage and fault alarm of information, and historical data query. The wireless transmission of data and the sharing of resources are realized through GPRS, which more effectively guarantees the safe operation of the train. solution Adopting Helicomm's MA8 series GPRS wireless data transmission terminal (DTU for short) and the sensors installed on the front of the train, such as temperature sensor, speed sensor, power sensor, etc., are connected through RS232 / 485 interface, and the collected data is uploaded to the GPRS wireless data transmission terminal and Internet The remote center end, through the collected data to understand the current status of the train in real time, and can send data to the controller in the train head to control some equipment, such as air conditioning and lighting in the car. GPRS (General Packet Radio Service) is a data transmission technology based on the global mobile phone system (GSM). It has a wide coverage and is suitable for long-distance data transmission of trains. The MA8 series GPRS DTU independently produced by Helicomm Company is powerful and has always online , Data triggering, SMS backup, remote modification, central call, support for fixed and mobile IP and other functions, reasonable and effective use of network resources, the system is stable and reliable. Why choose Helicomm 1. MA8 series GPRS DTU is powerful and has strong adaptability to customer needs. 2. MA8 series DTUs have multiple interfaces of RS232 / 485 / Ethernet port, and the system is flexible to set up. 3. The graphical device configuration interface simplifies the system installation cycle. 4. Has many years of research and development and industry experience, independent core technology.
