Problems solved by technology

[0002] In industrial and agricultural production, wireless network transmission of information data is becoming more and more widespread, but in important production and life occasions, it is often not allowed to have network disconnection, missing data transmission, inaccurate data transmission, slow data transmission speed, etc. And so on, the single-network wireless transmission mode of information data currently used in production practice, for example, only uses mobile wireless operators, or only uses Unicom wireless operators to carry out wireless network transmission of information data, although it can meet general needs. , but under the special industrial and agricultural production requirements, it can no longer meet the actual production requirements. A sensor signal dual-network wireless transmission device of the present invention can effectively solve the above-mentioned various problems

Abstract

The invention provides a sensor signal dual-network wireless transmission device, and belongs to the technical field of information transmission. The device is characterized in that: a corresponding signal is measured and sensed by a field sensor, is reasonably processed by each processing unit, is transmitted to an INATERNET network through two wireless data transmission operators, and is transmitted to a data acquisition analyzing and processing center by the INTERNET network. The device overcomes the defects of single wireless data transmission, and a sensor signal is subjected to wireless data transmission through two different network systems by using networks of two wireless data transmission operators; compared with currently adopted single network transmission of sensor data information, the dual-network transmission provided by the invention greatly improves the reliability of information data transmission, and effectively overcomes the defects that single circuit transmission is easily disconnected, easily loses data, wastes time and misses opportunities.

Description

Technical field: [0001] The invention relates to a dual-network wireless transmission device for sensor signals, which belongs to the technical field of information transmission. , rotational speed, line speed, current, voltage, power and turbidity physical quantities are measured by corresponding sensors to induce corresponding signals, which are firstly processed by each processing unit and then transmitted to the INATERNET network through two wireless data transmission operators Go, the device that transmits the signal to the data receiving, analyzing and processing center by the INTERNET network. The device adopts dual-network transmission, so it can effectively avoid the disadvantages of easy disconnection, data loss, time delay and opportunity delay in single line transmission. Background technique: [0002] In industrial and agricultural production, wireless network transmission of information data is becoming more and more widespread, but in important production and...
