Sewage discharge controller device

Abstract

The invention discloses a sewage discharge controller device. The sewage discharge controller device comprises a circuit board, a switching power supply part, a convertor, an external input signal transmission assembly, a protective resistance part, a single chip microcomputer chip and a crystal oscillation assembly, wherein the switching power supply part, the convertor, the external input signaltransmission assembly, the protective resistance part, the single chip microcomputer chip and the crystal oscillation assembly are arranged on the circuit board, the switching power supply part, theconvertor, the external input signal transmission assembly and the crystal oscillation assembly are all connected with the single chip microcomputer chip, the convertor is connected with the single chip microcomputer chip and the protective resistance part, and a wire outlet end of the convertor is connected with an external connection sewage pump. The sewage discharge controller device has the advantages that the functions of an intermediate relay, circuit breaker, rotary switch, inching switch, time relay, counter and other electrical components in a traditional control cabinet are replacedby a single chip microcomputer, the design is ingenious, the size is small, the functions are complete, the cost is low, a secondary loop signal power supply adopts human body safety voltage 5 volts,the occurrence of electric shock accidents is eliminated, and the sewage discharge controller device is suitable for being popularized and used in a water treatment system when the sewage pump or a whole set of system is controlled.

Description

technical field [0001] The invention relates to the field of controller systems, in particular to a blowdown controller device. Background technique [0002] With the continuous strengthening of domestic water environment resource protection awareness, the scope of use of sewage treatment equipment for people in various parts of the country continues to expand. When sewage treatment equipment is used for sewage treatment, it is usually necessary to form a complete set or an external sump pit, and the sump pit needs to be regularly discharged for sewage treatment. At present, many supporting sumps in China are equipped with sewage control cabinets, which have met the actual needs of sump sewage. However, many sump sewage control cabinets need regular maintenance. Due to the lack of maintenance professionals for sump sewage control cabinets, maintenance is highly technical; most of the signal sources of sump sewage control cabinets use AC 220V voltage, which is easy for maint...

Problems solved by technology

However, many sump sewage control cabinets need regular maintenance. Due to the lack of maintenance professionals for sump sewage control cabinets, maintenance is highly technical; most of the signal sources of sump sewage control cabinets use AC 220V voltage, which is easy for maintenance personnel to get an electric shock. In addition, the ordinary sump sewage control cabinet has a single function, which seriously affects the service life of the sewage pump
