Environment monitoring system of electric power communication cabinet

Abstract

The invention provides an environment monitoring system of an electric power communication cabinet. When the temperature is higher than a constant value, a fan is started to accelerate heat dissipation, and temperature and image information are transmitted to a remote terminal regularly; by adjusting the smoke concentration detection period, and by calculating the ratio of the electric signal increment caused by a first transmitting signal to the electric signal increment caused by a second transmitting signal, the smoke type is judged, so that a smoke alarm threshold value can be adjusted byselecting different adjusting modes according to different smoke types before a smoke sensor gives an alarm; the smoke alarm threshold value is increased if smoke is not generated by a fire, so that the sensitivity of the smoke sensor is reduced, and false alarm of the smoke sensor is avoided; and working environment indexes in the power cabinet can be collected in real time through the sensors and the collectors, so that monitoring personnel can know the environment condition in the power cabinet in time. A monitoring center is connected with a monitoring terminal, so that remote monitoring can be realized; and the monitoring center alarm module can timely inform monitoring personnel of environmental problems in the electric power cabinet.

Description

technical field [0001] The invention belongs to the technical field of electric power control systems, and in particular relates to an environment monitoring system for electric power communication cabinets. Background technique [0002] At present, the general power communication cabinet does not have a monitoring system, and it is necessary to check on the spot to understand the condition of the wire joints, which may easily lead to rust and damage of the terminal blocks and wiring components, damage the wiring switches, and even cause unstable wiring, affecting power transmission. [0003] Power communication cabinets generally have the problem of excessive temperature, and the continuous high temperature will easily affect the reliability of the operation of electronic components in the cabinet. Commonly used temperature control methods include air-cooled heat dissipation, air-conditioning cooling, etc. Generally, fans have low efficiency of blowing and cooling, and the ...

Problems solved by technology

When the power cabinet is working, a large amount of heat will be generated inside. If the heat dissipation is not timely, it will have a certain impact on the operation of the internal devices of the power cabinet; because the power cabinet needs to dissipate heat, it is usually equipped with cooling holes, and the power cabinet is in the process of long-term placement. Dust will definitely enter the inside of the power cabinet. If it is not cleaned in time, the dust will accumulate more and more, which will cause damage to the internal devices of the power cabinet; if the current power cabinet is sent to monitor it at all times, it will greatly increase the burden on the workers.

[0004] Due to the limited protective effect of the cabinet and the harsh environment, such as wind, rain, sun exposure, accumulated water and snow, etc., the environment changes drastically, which may easily lead to damage to electrical equipment. There are a large number of power components inside the cabinet. , a large amount of heat will be generated inside, therefore, heat dissipation windows must be installed on the side wall of the power cabinet, but only through the heat dissipation windows for heat dissipation, the effect is not good, and the temperature and humidity inside the power cabinet cannot be reliably regulated, which is likely to cause failure of power components , due to the large number of power cabinets, it is impossible to monitor the internal environment of the cabinet in real time. Therefore, the life of the power cabinet is not only short but also prone to irreparable losses during use, especially in high-voltage and high-current environments.
