Monitoring and controlling system for sealed space environment

Abstract

The invention discloses a monitoring and controlling system for a sealed space environment. The monitoring and controlling system comprises a treatment unit, a perception unit, a controlling unit and the like, wherein the perception unit comprises a digital input module, a first A / D conversion module and a second A / D conversion module; the digital input module is connected with a water ingress alarm sensor and a smoke sensor through lead wires; and the second A / D conversion module is connected with a sulfur hexafluoride sensor through a lead wire. The controlling unit comprises a first digital output module and a second digital output module, wherein the first digital output module is connected with an external air door driving module, an internal air door driving module, an outdoor machine driving module, a cold-hot mode conversion driving module and a dehumidification driving module through lead wires. The monitoring and controlling system for the sealed space environment is characterized in that the first digital output module is also connected with a waste heat valve driving module through a lead wire. The monitoring system provided by the invention can be utilized to shorten ventilating and cooling time, improve working efficiency and prolong service lives of electric equipment.

Description

technical field [0001] The invention relates to a monitoring system, specifically an intelligent monitoring control system for improving the environment of a closed space, applicable to substations in the electric power industry, computer control centers in the telecommunications industry, and environmental monitoring centers in the pharmaceutical industry. Background technique [0002] At present, in closed spaces such as substations, computer control centers, and environmental monitoring centers, it is necessary to install many high-voltage and high-energy-consuming equipment. It is built in a sparsely populated area or underground, and then implements remote monitoring and control of the operation and environmental conditions of its internal equipment through the monitoring system, so as to ensure that the system composed of these equipment can operate safely and stably. [0003] Most of the traditional monitoring systems have the functions of cooling and ventilation, fir...

AI Technical Summary

Problems solved by technology

[0004] However, since most of the equipment used in this type of closed space is high-voltage, high-energy-consuming electrical equipment, these equipment generate a lot of heat during operation, and the above-mentioned monitoring system often drives the internal and external dampers, outdoor units, and dehumidifiers. During operation, it takes a long time to reduce the temperature / humidity data in the closed space to the range of the monitoring data, and during this cooling time, the power equipment is still operating in an abnormal environment of high temperature and high humidity

Therefore, this monitoring system is not only inefficient in cooling and ventilation, but also shortens the service life of electrical equipment

[0005] In addition, the traditional monitoring system usually only has the above four functions, which still cannot fully ensure the quality of the environment in the enclosed space, and additional environmental auxiliary monitoring devices (such as sterilization and dust removal, infrared monitoring, etc.) will increase the quality of the enclosed space. Internal power consumption, resulting in waste of energy

Moreover, these monitoring devices are still small automatic devices that are independent of each other and have no dialogue function. Manual attention, understanding and control of the information of these devices are required, and the functions of online monitoring, automatic control, intelligent adjustment, and collaborative interaction cannot be realized.
