Market demand
The application field of automatic weighing system is very wide, such as steel plants, coal mines, factories, etc., all need to collect and monitor the weighing data of incoming and outgoing cargo vehicles. Generally, the weighing system of the factory is assigned by a special person to weigh the key points. Manual monitoring in the weighing application environment is very fragile and prone to errors, and it is easy to cause system loopholes due to human factors, which is also a great waste of human resources. The automatic weighing remote wireless monitoring system developed by Helicomm based on the advanced ZigBee technology adopts the self-organized wireless mesh network of ZigBee technology as the communication medium. Resource utilization improves the work efficiency of the entire system.
solution
The terminal part of this system is composed of weighing instrument and IP-Link2220ZigBee wireless data transmission terminal independently developed by Helicomm; the central part is composed of IP-Link2220ZigBee wireless data transmission terminal and PC connected. As shown in the figure, the weighing data collected by the weighing instrument is transmitted to the central end through the ZigBee wireless mesh network. The central end can also send commands to the weighing instrument control switch, reset and other operations through the ZigBee wireless mesh network. The system supports multi-point data Collection and monitoring, improve system work efficiency and effectively avoid human loopholes.
System maintenance is convenient and supports remote wireless firmware update and configuration. IP-Link2220 wireless data transmission terminal is equipped with industrial standard RS232/485 interface; 16 communication channels can be selected flexibly; CSMA/CA anti-collision mechanism can avoid the occurrence of packet loss caused by multi-point high-speed data transmission, making the system more stable and accurate.
