A solid state programming circuit

Abstract

The invention discloses a solid-state programming circuit. The solid-state programming circuit comprises a signal input circuit module, an intermediate-stage amplifier circuit module, an integral circuit module, a voltage-current conversion circuit module and a power supply module. The signal input circuit module controls voltage signals output to the intermediate-stage amplifier circuit module according to received switching signals so as to enable the intermediate-stage amplifier circuit module to amplify the voltage signals and then output the voltage signals to the integral circuit moduleto be integrated, thus the integrated voltage signals are obtained, the voltage-current conversion circuit module can convert the integrated voltage signals into current signals to be output, the actual demands of various application occasions are met, in addition, the signal input circuit module can select voltage signals output by multiple paths of signal input units according to the actual situation, thus the shunt span is small and flexible, the precision of the output result is increased, the solid-state programming circuit is simple in circuit structure and high in integration level, thus circuit response is sensitive, and safe and stable operation of equipment can be ensured.

Description

technical field [0001] The invention belongs to the technical field of automatic control, in particular to a solid-state programming circuit. Background technique [0002] At present, the solid-state programming circuit used in the logic control system of nuclear power plants contains many short-life components, including electrolytic capacitors, diodes, relay contacts, high-power equipment power supplies, hot terminals, and fuses, etc., making solid-state programming circuits A large number of components are used, resulting in redundant circuit structure, which makes the solid-state programming circuit unresponsive. At the same time, due to the short life of the components used, the circuit is prone to failure, making the equipment unable to operate safely and stably; in addition, due to the traditional solid-state programming The circuit can only input voltage signals in a fixed way, but cannot select one or more channels to output voltage signals in the multi-channel sign...
