Intelligent safe socket with power amplifying circuit

Abstract

The invention discloses an intelligent safe socket with a power amplifying circuit. The intelligent safe socket comprises a power module, a shell, electrode plates, pressure sensors, a single-chip microcomputer and a relay, wherein socket holes are formed in the shell, two electrode plates are arranged at the positions, corresponding to each socket hole, of the inner wall of the shell, and each pressure sensor is arranged between the two corresponding electrode plates; signals detected by the pressure sensors are transmitted to the single-chip microcomputer, and the single-chip microcomputer controls the relay to act according to the signals received from the pressure sensors; the power module provides direct current for the single-chip microcomputer, a Hall current sensor and an intelligent circuit breaker are arranged on a bus connecting the socket with a power supply, and a sampling circuit, a filter circuit and the power amplifying circuit are sequentially connected between the pressure sensor and the single-chip microcomputer; the power amplifying circuit comprises an operational amplifier A1, an operational amplifier A2, an operational amplifier A3, a triode T1 and a triode T2, and the inverted input end of the operational amplifier A1 is connected with the output end of the operational amplifier A. The intelligent safe socket has the advantages that electric shock can be avoided, and the safety of the socket can be improved.

Description
