chrispeng [ad_1]
For some important places that need to strictly control the ambient temperature, such as large-scale communication rooms and computer rooms, it is generally necessary to set up a temperature monitoring system when designing a weak current system, in order to protect specific assets or ensure the smooth operation of the system. In addition to the computer room, these places also include television stations, cable channels, control computer rooms (cabinet), power plants, substations, as well as warehouses, grain warehouses, cold storage, shopping malls, food factories, pharmaceutical factories, wineries, beverage factories, etc., which require large areas. A storage center for temperature measurement and monitoring of a range. In addition, in transportation areas such as subways, tunnels, railways, airports, cabins, and dangerous goods areas such as oil tanks, gas tanks, coal silos, military factories, and ammunition depots, temperature monitoring is usually the most basic environmental monitoring element. In this program, we take the temperature monitoring of the computer room as an example to illustrate the application requirements and application principles of the company’s temperature label product SP-THT-100 in these temperature control fields.
With the rapid development and rapid popularization of domestic information technology, the number of computer systems and communication equipment in various application fields has increased exponentially, and computer rooms (computer centers, equipment rooms, wiring closets, base stations, etc.) have become various enterprises and institutions The core platform of business management; the computer room equipped with network equipment, computer servers and other communication equipment has become an important place for data exchange and storage, and special measures are required to protect it. As shown in the figure below, a typical computer room control system includes an access control system, an image monitoring system, a temperature and humidity system, a network monitoring system, etc., which carry out a full range of monitoring and management of the computer room. Among them, the temperature and humidity of the computer room are two very important environmental parameters, which are necessary conditions for the normal operation of computer equipment. According to a statistical survey, the reliability of computers decreases by 25% every time the temperature rises by 10°C, and the magnetic tape will cause recording errors due to thermal expansion. The clock frequency of the computer will decrease when the temperature is too high or too low. For this reason, the management of many computer rooms currently uses 24-hour dedicated personnel to regularly inspect the equipment in the computer room, which not only increases the burden on personnel, but also often fails to eliminate faults in time. Using the computer room environment monitoring system, the information monitored by the computer room can be effectively collected and processed in a larger area in a faster way, fault alarms are found to be resolved at any time, security risks are recorded and comprehensively analyzed, and finally solutions are sought. .

application solution
In order to meet the increasing demand for computer room temperature monitoring, Shanghai Xiupai Electronic Technology Co., Ltd. recently launched a computer room temperature monitoring system based on active RFID technology. Through advanced active RFID technology, where appropriate temperature monitoring and management are required to ensure asset quality and smooth operation requirements, the collected environmental temperature data is continuously recorded in the active electronic tag and transmitted to the background wirelessly In the monitoring system, the troubles of manual inspections and network wiring are eliminated, and work efficiency is improved.
In a general computer room, the network equipment or servers installed in the network cabinets and server cabinets are important equipment. They are heat-generating electronic devices and must operate under a certain temperature and humidity environment. Once the fan in the cabinet fails or the air conditioner stops operating, The cabinet temperature will be very high, exceeding the ambient temperature of the network equipment or server operation, will affect the normal operation of the equipment, and then affect the normal business operation of enterprises and institutions.

The application principle of temperature monitoring based on active RFID technology is very simple: install temperature and humidity sensor tags in the main equipment working rooms of the computer room to detect temperature and humidity in real time. After receiving temperature and humidity data, the temperature and humidity tags can periodically go far away. The distance reader sends data, which is transmitted to the background in real time and displays the temperature and humidity values of each measuring point on the monitoring screen. Through software tools, these continuously sent data can form a temperature curve to display the current change trend of the temperature of the computer room. When any detected value exceeds the upper and lower limits of temperature and humidity specified in each working area, the corresponding monitoring screen An eye-catching indicator flashing can be used next to the data to remind the value of the over-limit alarm. In the case of equipment abnormalities, various forms of alarms are used to notify the corresponding personnel, so that no one or a few people are on duty in the monitoring of the computer room, which provides a strong guarantee for the efficient management and safe operation of the computer room.
The system combines SMS and GSM short message technology and utilizes the global resources of the Internet to create a low-cost, feature-rich unattended computer room solution. When there is an abnormality in the computer room, a short message alarm can be set up, short message group sending can be set, and different personnel on duty can be notified at different times. The system can send short messages and e-mails about the current operating conditions of equipment in the computer room through mobile phone or telephone ringing, and e-mail, fully realizing unattended remote monitoring.
As the chief supplier of domestic active RFID products, Shanghai Supai provides high-quality temperature sensor tags that have undergone a large number of field tests and case verifications. At present, the temperature label provided by our company has the following characteristics:
1. The data storage capacity is large, and the maximum user space can be expanded to 256KB;

9. Intranet monitoring function: After authorization, office users in the local area network can read the real-time data on the monitoring host to realize remote monitoring. The system can be monitored not only in the duty room, but also very convenient for leaders in their own office.At the same time, other authorized users on the Internet can obtain and understand the real-time information in the computer room
10. Mobile phone remote monitoring function: The system can send a short message of the current computer room temperature and equipment operation status through the ringing of the mobile phone or the phone. The calling number is filtered, and only the set number can prompt the system to send short messages of operating conditions and improve the security of the system (Note: This function requires the SIM card to enable caller ID display)
