Vehicle-mounted mobile substation temperature and humidity remote monitoring device

Abstract

The invention discloses a vehicle-mounted mobile substation temperature and humidity remote monitoring device, which comprises an input module, a power supply module, a controller and an output module, wherein the input module is composed of a temperature and humidity sensor, a real-time clock, keys and an EEPROM; the power supply module is composed of a rechargeable battery and battery management; the output module is composed of a sound-light alarm, a GSM and a liquid crystal display, and the sound-light alarm is connected with an alarm; the GSM is connected with an antenna; the power supply module is connected with a charging interface; the controller and the liquid crystal screen of the liquid crystal display have an 18-core interface, and a backlight control circuit composed of a power supply, a control and data bus, a triode and two resistors is included; and the real-time clock comprises a built-in oscillator, the first pin and the second pin of the oscillator are connected with a stable crystal oscillator, and a clock source is slightly adjusted through a ninth capacitor and an eleventh capacitor. The vehicle-mounted mobile substation temperature and humidity remote monitoring device has the advantages of simple structure, reliable use, convenient operation, strong generality and the like.

Description

technical field [0001] The invention relates to a remote temperature and humidity monitoring device for a vehicle-mounted mobile substation, and belongs to the technical field of temperature and humidity monitoring for a mobile substation. Background technique [0002] With the continuous development of society, users have higher and higher requirements for power supply quality. During the transformation of the system, there are situations where the user’s power supply cannot be transferred, resulting in a power outage for the user; at the edge of the power supply radius, the power quality is not ideal; or in the event of an accident, the power outage of important users has to be caused. The mobile substation can satisfactorily solve the above problems. It has strong mobility and can go to the site according to the needs to ensure the normal power consumption and power quality of users. [0003] It is precisely because of the transportability of the mobile substation that i...

Problems solved by technology

Because there is no corresponding temperature and humidity monitoring device, the operation and maintenance personnel cannot timely grasp the temperature and humidity in the box, especially when the external environment is harsh, the operating environment temperature and humidity of the protection measurement and control device for the low-voltage outgoing line will exceed its allowable range, and the long-term operation will cause serious problems. It may lead to misoperation or refusal of the protective device, which will cause immeasurable economic losses and even endanger personal safety.
