How to install and select different environmental temperature and humidity sensors in the computer room?
With the rise and rapid development of the Internet, the amount of information on the Internet in China is increasing, which has also promoted the growth of data center computer rooms. The computer room has become an important place for enterprises and related units to store, process, and share data. To ensure The normal operation of the server or IT equipment in the computer room and the environment of the computer room have been paid attention to by the operation and maintenance personnel. The computer room is mainly used to store important IT equipment. In order to ensure the normal operation of the computer room, the data center computer room must be kept within a constant temperature range. The rise and fall of indoor temperature and humidity will directly affect the working conditions of the equipment, so the temperature and humidity sensor Become an indispensable part of the engine room power environment monitoring system. Various types of IT electronic equipment will heat up and generate heat during long-term operation, which will affect the performance of the equipment. In addition, heat-generating equipment will release a certain amount of heat into the air through heat dissipation, causing local ambient temperature to rise. How to choose and install temperature and humidity sensors for different places in the computer room? 1. Computer room environment. Install temperature and humidity sensors on the wall or ceiling of the computer room to detect the overall temperature and humidity of the computer room. The temperature and humidity of each area of u200bu200bthe computer room can be quickly understood according to the location of the sensor. For the temperature and humidity monitoring of the entire computer room, it is recommended to install 86 housing temperature and humidity sensors to monitor the real-time temperature and humidity of each computer room environment. When the data exceeds the limit, it will alarm and activate the air conditioning controller to adjust the temperature. The 86 housing temperature and humidity sensor has a liquid crystal display, real-time display of temperature and humidity, screw-free terminal wiring on the back, and can be installed on a standard 86mm junction box. The equipment adopts standard MODBUS-RTU communication protocol, RS485 signal output, and the maximum communication distance can reach 2000 meters (measured). The probe is built-in and the extension is optional. Its products are safe, reliable, beautiful in appearance and easy to install. 2. Equipment environment The equipment environment is mainly for equipment such as ventilation ducts. Temperature and humidity sensors are installed at these equipment to judge the temperature and humidity. For the temperature and humidity monitoring in the ventilation ducts, it is recommended to install air duct temperature and humidity sensors to monitor the real-time temperature and humidity of the ventilation ducts in the computer room. When the data exceeds the limit, SMS, phone, email, etc. will be used to notify the management staff to take measures in time . The air duct temperature and humidity sensor adopts an imported temperature and humidity measurement unit, which has small drift and high accuracy. The equipment adopts the standard Modbus-RTU protocol, the communication address and baud rate can be set, and the communication line can be up to 2000 meters long. It supports secondary development; the equipment can upload data to our environmental monitoring software or collect data by itself. The pipeline installation method is convenient for on-site installation and adopts anti-interference circuit design, which can withstand various strong electromagnetic interferences such as on-site inverters. 3. Cabinet environment A cabinet is a carrier for installing servers, switches and other equipment. The temperature and humidity in the cabinet are related to the location of the cabinet and the number of equipment installed in the cabinet. Therefore, installing the temperature and humidity in the cabinet will be more conducive for managers to judge the temperature and humidity of the equipment room. For the internal temperature and humidity monitoring of the cabinet, it is recommended to install a flat rail housing temperature and humidity sensor for monitoring the real-time temperature and humidity inside the cabinet. The flat rail housing temperature and humidity sensor has a built-in sensor, which is small in size and has a standard DIN35 rail mounting card, which can be directly used for rail installation. The product is widely used in power distribution cabinet installation, and can also be wall-mounted. The 485 communication interface standard ModBus-RTU communication protocol, the communication address and baud rate can be set, and the communication distance is up to 2000 meters. For a computer room with a large area, due to the influence of airflow and equipment distribution, the temperature and humidity values u200bu200bwill have a big difference. It should be based on the actual area of u200bu200bthe host room and the actual placement of the server. Determine the number of additional temperature and humidity sensors to monitor the temperature and humidity in the equipment room. The monitoring of the temperature and humidity in the computer room not only allows managers to understand the temperature and humidity conditions and reasonably arrange the placement of the equipment, but more importantly, it can quickly notify the management for processing when the temperature and humidity are abnormal. The temperature and humidity sensor is integrated with the monitoring software to realize remote control functions such as over-limit call/message alarm. Cooperate with the precision air conditioner to automatically adjust the indoor temperature and humidity to provide the safest and most effective protection for the computer room. Temperature and humidity monitoring has an indispensable position in the construction of the computer room and will play an increasingly important role.
