Problems solved by technology

[0002] The control system of the vehicle toilet mainly controls the products through the various components in the control system. The components in the control system mainly include relays, solenoid valves, electric control valves, etc. Now most of the control systems of the vehicle toilet are separated. The component failure rate is high, the fixed control logic is poor, and all are manually operated, which limits mass production and cannot be remotely controlled. Its monitoring and control are not intelligent and flexible enough

Abstract

The invention discloses a vehicle-mounted toilet PLC control system, and relates to the technical field of vehicle toilets. The vehicle-mounted toilet PLC control system comprises an encoder, a power supply control loop, an air flow control loop, a water flow control loop, a COM, a speed setting device, a scale indicator switch, a point upper loop and a point lower loop. The control system disclosed by the invention is low in failure rate of separate components, is good in logic of fixed control, can perform remote control, and is more intelligent and more flexible in monitoring and control.

Description

technical field [0001] The invention relates to the technical field of vehicle toilets, in particular to a PLC control system for vehicle toilets. Background technique [0002] The control system of the vehicle toilet mainly controls the products through the various components in the control system. The components in the control system mainly include relays, solenoid valves, electric control valves, etc. Now most of the control systems of the vehicle toilet are separated. The component failure rate is high, the fixed control logic is poor, and all are manual operations, which limits mass production, and remote control is not possible, and its monitoring and control are not intelligent and flexible enough. Contents of the invention [0003] The purpose of this invention is to provide a kind of vehicle-mounted toilet PLC control system, the hardware logic of its relay control system can be described by logic function expression, the control logic that this logic function exp...
