Why?
Relative to the traditional manual collection equipment, wireless data collector is more advanced, because it can be directly through the wireless network and PC, server for real-time data communication. Wireless data collector communication data in real time, high efficiency.
It includes two parts of the core function: wireless data transmission function and data collection function.
Wireless data transmission network is usually Zigbee, Wifi, GPRS, 3G, 4G, etc.; generally lower overall cost and more stable performance. Only one-time investment, no need to dig trench deep buried pipe, especially suitable for outdoor distance and has been decorated occasions.
The content of the acquisition is usually for the sensor common output signals, such as: ± 10V voltage signal, or 4 ~ 20mA current signal, or common conditioning circuit (PT100, thermocouples, bridges and other conditioning circuit).
Wireless collector of these two parts of the function combined together to achieve the acquisition of field data and wireless transmission, can get rid of the shackles of the cable, there is a short cycle of installation, easy maintenance, capacity expansion, rapid recovery of the cost of the advantages.
Wireless data collector its working principle:
Through the GPRS wireless network will be the user equipment data transmission to the host computer on the Internet, to realize the data remote transparent data transmission. It is embedded in the GPRS unit, integrated under the CPAP protocol, fully transparent transmission, always online, automatic reconnection. It can be directly connected with various user devices that need remote wireless communication through serial port, such as intelligent instruments, meters, PLC, DCS, data terminal, RDU, touch screen, industrial control machine, etc. Meanwhile, it can realize the configuration of free protocol and MODBUS protocol with the industrial control products such as the configuration software, human-machine interface, touch screen, measurement and control terminal, etc., and it can be applied to electric power monitoring, oil field monitoring, remote meter reading, It can be applied in many fields such as electric power monitoring, oil field monitoring, remote meter reading, street light monitoring, environment monitoring, weather monitoring, water conservancy monitoring, heat network monitoring, and so on.
Wireless data collector data collection is accurate, and anti-interference is very strong, its appearance effectively solve the problem of industrial field data collection. It is a very great invention.
