MODBUS Protocol Multipath Temperature Measuring System

The Internet of Things refers to the connection of any object to the network through information sensing equipment according to an agreed agreement, and the object exchanges and communicates through information media to realize intelligent identification, positioning, tracking, supervision and other functions.

In industrial control, it is often necessary to convert various non-electrical physical quantities such as temperature, pressure, speed, and angle into analog electric signals for transmission.Among them, the 4-20mA current signal is a widely used analog signal. This transmission mode has simple communication mode, strong anti-interference ability, and relatively reliable fault diagnosis function.

This solution is especially designed for the Multi-path weighting detection acquisition system which hasdifficulties in wiring, it is one of typical
