Assembled low-voltage internet-of-thing intelligent monitoring system

Abstract

The invention provides an assembled internet-of-thing low-voltage intelligent monitoring system, and belongs to the technical field of internet-of-thing low-voltage monitoring. The system comprises anintelligent detection system, a cloud platform and an intelligent terminal. The intelligent detection system comprises a signal acquisition module, a microprocessor, a key setting module, a display module, a pluggable wireless communication module, a wired communication interface and an alarm module; and in the microprocessor, the acquired voltage, current and residual current are compared with corresponding reference values to judge whether the alternating current circuit breaks down or not; the collected voltage, current and residual current are compared with corresponding reference early warning values on the cloud platform to judge whether early warning occurs in the circuit or not, wherein the reference values and the reference early warning values can be modified online or offline on the key setting module or the cloud platform. Compared with an existing internet-of-things low-voltage intelligent monitoring system, the assembled internet-of-thing low-voltage intelligent monitoring system can adjust the reference value according to changes of circuits, and circuit early warning or fault information can be sent to intelligent terminals of maintenance personnel in real time.

Problems solved by technology

However, this solution still has the disadvantage of not being able to judge the fault of zero and phase loss of the circuit, and the reference voltage value, reference current value and reference residual current value cannot be modified locally or remotely. In addition, the detection module and the actuator are placed in the same device , due to volume limitations, the carrying capacity of the equipment is severely limited
