Multifunctional intelligent power utilization monitoring terminal

Abstract

The invention discloses a multifunctional intelligent power utilization monitoring terminal. The terminal comprises a shell used for installation and fixation, a circuit board is arranged in the shell, and a front-end module and a rear-end module are configured on the circuit board; the front-end module comprises an acquisition circuit, a fault arc detection circuit, a driving circuit, a reference frequency sampling circuit, a signal output circuit, a communication circuit and a first main control circuit; and the rear-end module comprises an electric arc processing circuit and a second main control circuit. The terminal further comprises a power supply circuit used for supplying power to the front-end module and the rear-end module. With the multifunctional intelligent power utilization monitoring terminal adopted, electric arc collection can be achieved, the purpose of electric arc recognition is achieved through analysis of high-frequency and low-frequency data and filtering shaping; and electric arc detection and recognition functions are additionally arranged for an existing electric meter box device, so that the use safety can be guaranteed.

Description

technical field [0001] The invention relates to the fields of fault detection and electric meter devices, in particular to a multifunctional smart electricity monitoring terminal. Background technique [0002] At present, the civilian electric meter box devices widely used in the country have basically the same internal structure except for the difference in appearance, that is, the front switch of the meter, the circuit breaker behind the meter, the electric energy meter, the switch, the circuit breaker and the necessary connecting devices adopt common wires, screws, etc. Fasten the connection. [0003] However, these meter box devices only have the function of leakage protection. In order to prevent electric shock accidents or fires caused by leakage, as well as various safety accidents caused by overcurrent, the leakage on the line will be detected. If the leakage exceeds the set value, A trip signal is then sent to the trip coil to trip the circuit breaker. [0004] Ho...
