Market demand As the speed of trains increases, the implementation of train monitoring is of great significance. 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 of information, storage and fault alarm, 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 trains.
The solution uses Helicomm’s MA8 series GPRS wireless data transmission terminal (DTU for short) and the sensors installed on the train head, such as temperature sensor, speed sensor, power sensor, etc., are connected through the RS232/485 interface, and the collected data is connected through the GPRS wireless data transmission terminal and the Internet Uploaded to the remote center terminal, the remote center terminal learns the current status of the train in real time through the collected data, and can send the data to control some equipment in the train head controller, such as the 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 by trains. The MA8 series GPRS DTU independently produced by Helicomm has powerful functions and is always online. , Data trigger, 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 has powerful functions and strong adaptability to customer needs.
2. MA8 series DTU has multiple interfaces of RS232/485/Ethernet port, which makes the system flexible.
3. Graphical equipment configuration interface simplifies the system setup cycle.
