Abstract

The invention discloses a low voltage intelligent measurement and control protection circuit structure of a switch cabinet. The low voltage intelligent measurement and control protection circuit structure of the switch cabinet comprises a single chip microcomputer and a temperature and humidity module. The single chip microcomputer is connected with the temperature and humidity module, a temperature and humidity collecting chip is arranged in the temperature and humidity module. The temperature and humidity in the switch cabinet can be tested by the single chip microcomputer and the temperature and humidity module, and can be showed through a man-machine interface and other display windows, the low temperature and high humidity conditions in the switch cabinet can be preset, when the conditions are reached, other devices can be started to increase the temperature in the switch cabinet and lower the humidity in the switch cabinet, the switch cabinet can be protected, and device burned situation caused by condensation because of the low temperature and high humidity of the switch cabinet can be avoided.

Description

Low-voltage intelligent monitoring and protection circuit structure in a kind of switch cubicle
Technical field
The present invention relates to low-voltage intelligent monitoring and protection circuit structure in a kind of switch cubicle, belong to electric and electronic technical field.
Background technology
Existing intelligent measuring and control device or circuit are unfavorable for that the temperature and humidity in switch cubicle carries out monitoring and measuring, conventionally switch cubicle is for a long time in the working environment in high humility, because the appearance of low temperature causes occurring on the electrical equipment in switch cubicle condensation phenomenon, cause electric short circuit, burn switch cubicle; In addition, at present in order addressing the above problem, in switch cubicle, to install temperature and humidity measurement and supervision product in switch cubicle additional, to cause the cost of switch cubicle to raise, cause whole system maintenance workload to increase simultaneously.
Summary of the invention
For the technical matters of above-mentioned existence, the object of the invention is: proposed a kind of can to switch in-cabinet temperature and humidity measure and the switch cubicle protected in low-voltage intelligent monitoring and protection circuit structure.
Technical solution of the present invention is achieved in that low-voltage intelligent monitoring and protection circuit structure in a kind of switch cubicle, comprises single-chip microcomputer and humiture module; Described single-chip microcomputer is connected with humiture module; In described humiture module, be provided with humiture collection chip.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Low-voltage intelligent monitoring and protection circuit structure in a kind of switch cubicle of the present invention; realize the temperature and humidity in detector switch cabinet by the single-chip microcomputer and the humiture module that arrange; show by man-machine interface and other display windows simultaneously; and preset the condition of the interior low temperature of switch cubicle and high humidity; reach and start the humidity that other equipment increase the temperature in switch cubicle and reduce switch cubicle after condition, protection switch cabinet is avoided causing equipment burnout because low temperature and high humidity cause switch cubicle because of condensation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the schematic diagram of low-voltage intelligent monitoring and protection circuit structure in a kind of switch cubicle of the present invention;
Accompanying drawing 2 is the single chip circuit schematic diagram of low-voltage intelligent monitoring and protection circuit structure in a kind of switch cubicle of the present invention;
Accompanying drawing 3 is the humiture modular circuit schematic diagram of low-voltage intelligent monitoring and protection circuit structure in a kind of switch cubicle of the present invention;
Wherein: 1, single-chip microcomputer; 2, humiture module.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1-3 is low-voltage intelligent monitoring and protection circuit structure in a kind of switch cubicle of the present invention, comprises single-chip microcomputer 1 and humiture module 2; Described single-chip microcomputer 1 is connected with humiture module 2; In described humiture module 2, be provided with humiture collection chip.
The inside MCU (central microprocessor) of single-chip microcomputer 1 and humiture module 2(SHT10) between by iic bus (SCL/SDA) line connect; Humiture module 2(SHT10) be the module of a digital measurement temperature and humidity, i.e. humiture collection chip.Demonstration and the indication of the setting of demonstration, low ambient temperature and humid environment that the man-machine interface of single-chip microcomputer 1 mainly completes the temperature and humidity of switch cubicle after with the action of low ambient temperature and humid environment; The DO output of single-chip microcomputer 1 is mainly controlled (object of DO output is relay output) by MCU, when detecting controller internal temperature, MCU exceedes after man-machine interface set environment low temperature and humid environment, MCU sets high the mouth line of GPIO, the actuating of relay, start the heating rod that is contained in advance in switch cubicle and add gentle wet down to switch cubicle, disconnect relay after reaching predefined rreturn value simultaneously; The communication interface of single-chip microcomputer 1 mainly completes the data interconnection between multiple devices, is concentrated and is shown simultaneously by running background software.
The present invention program realizes the temperature and humidity in detector switch cabinet by the single-chip microcomputer 1 and the humiture module 2 that arrange; show by man-machine interface and other display windows simultaneously; and preset the condition of the interior low temperature of switch cubicle and high humidity; reach and start the humidity that other equipment increase the temperature in switch cubicle and reduce switch cubicle after condition, protection switch cabinet is avoided causing equipment burnout because low temperature and high humidity cause switch cubicle because of condensation.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
