1.1 The Necessity of the System With the development and popularization of computer technology, the number of computer systems is increasing day by day, and the supporting environmental equipment is also increasing. The computer room has become an important part of major units. The environmental equipment of the equipment room has increasingly strict requirements on temperature, humidity, and safety. This is the basic environment that ensures the normal operation of the computer system. Once the engine room environment equipment fails, it will affect the operation of the computer system, and it poses a threat to the reliability of data transmission, storage, and system operation. If the accident is serious and cannot be handled in time, it may damage the hardware device and cause serious consequences. For a unit room like China Mobile that needs to exchange data in real time, the management of the equipment room is more important. Once the system fails, the economic loss caused is incalculable. At present, many computer room management personnel have to use 24-hour personnel on duty, regular inspections of the engine room environment equipment, which not only increases the burden on management personnel, and more time, can not be timely troubleshooting, no time and responsibility for the accident and science Management.

3 Design Plan In line with the principle of establishing a safe, practical and advanced machine room monitoring network for users, we will discuss the design scheme in the following sections based on the actual situation of the user.
3.1 Monitoring System Structure The system is divided into two layers: the monitoring center and various monitoring equipment on site.
monitoring Center:
The monitoring center consists of IPC, monitor, console, large-screen LCD display, serial capture card, monitor support, protocol conversion module, video recording card, video plug, video cable, speaker and sound card. The monitoring center will collect all real-time data, video streams and alarm content, and respond to all events in a unified manner.
The monitoring host and the smart device are connected via RS485/232 or network. The master-slave mode is used to communicate with each other through the communication protocol to obtain real-time data of each device, which facilitates immediate response to events.
Monitoring site:
Digital temperature and humidity sensors and color dome cameras.
3.2 Monitoring objects and contents According to user requirements, the main monitoring contents are as follows. The following will introduce each monitoring subsystem separately:
3.2.1 Room Temperature and Humidity Monitoring System
3.2.1.1 General description: For a large room, due to the influence of air flow and equipment distribution, the temperature and humidity values ​​will be different. The temperature and humidity sensors should be determined according to the actual area of ​​the host room and the actual placement of the server. The number of detected temperature and humidity in the room. 
China Mobile Computer Room Monitoring Program
1 Overview
Through the linkage between the sensor and the IPC in the main monitoring room, real-time display of the temperature and humidity in the equipment room can be realized. When the preset value is exceeded, the system will send out an alarm sound to remind the site management personnel; and the system can be reserved inside the software for future expansion needs. A wireless cat communication interface is provided, and a wireless cat card slot is reserved on the hardware so as to facilitate the need to implement an SMS alarm function in the future.
3.2.1.2 Temperature and humidity system monitoring The rough structure diagram is as follows:
3.2.1.3 Hardware Configuration: According to the actual area of ​​use of the server room, the specific configuration of each room sensor
1# computer room: The actual usage area of ​​the server is about 100 square meters, and a temperature and humidity sensor is installed at 10/ m2. Then 1# machine room needs 10 temperature and humidity sensors, and another 1# machine room also separates out a small single room. About 13 square meters, there is a need to install a temperature and humidity sensor, so that the total number of temperature and humidity sensors required in the 1# room is 11 .
The structure is as follows :
Room 2# : The actual area of ​​use of the server is about 60 square meters, and a temperature and humidity sensor is 10 square meters, so 6 temperature and humidity sensors are needed.
The structure is as follows:
3 # room : The actual use of the server area of ​​about 180 square meters, a temperature and humidity sensor / 10 square meters, so you need 18 temperature and humidity sensors.
The structure is as follows :
4# computer room : The actual use area of ​​the server is about 200 square meters, but the existing area of ​​4 rows of servers is about 80 to 90 square meters, so a temperature and humidity sensor of 10 square meters requires 8 temperature and humidity sensors. If you need to take into account the server to be installed in the future, that is, the remaining four rows of servers, the overall need for temperature and humidity sensors is 16.
The structure is as follows:
5# computer room: The actual usage area of ​​the server is about 300 square meters, and there are 12 rows of servers. However, there are only 1 rows of existing servers , and the area is approximately 10 square meters. Two temperature and humidity sensors are required. If you consider the server to be added later, the overall required temperature and humidity is 30 .
The structure is as follows:

3.2.1.9 Comparison of Performance of Similar Products
Ø       Comparison of JCJ100N and Switzerland integrated SHT temperature and humidity sensors:
Ø       JCJ100N: The integrated design of the output signal, integrates the temperature and humidity communication circuit, and directly outputs the standard RS485 signal. No other data acquisition card and other collectors are required for data acquisition. The serial port of the computer can be directly read by the computer to facilitate the use of the client. 485 data signals can be directly transmitted without the relay 1200 meters, good anti-interference performance.
Ø       SHT: small size, integrated design, I 2 C signal output, the signal transmission distance of up to 7 meters, the signal can not be directly read by the computer, in the middle must be added to a collector, the collector and the sensor must be a one-to-one correspondence , Through the collector into a computer can read data, increase the cost, inconvenient to use. In addition, the product temperature sensitive components and circuits are integrated on a circuit board of approximately 1 square centimeter. In actual use, the heat of the circuit itself will affect the accuracy of temperature sampling. The temperature parameter of the product is a theoretical parameter, in real standard time, and the ambient temperature. There will be more than one degree of error, which is the biggest reason why we do not use this form of temperature measurement.
3.2.2 Video Surveillance
3.2.2.1 Overview: Real-time monitoring of the monitoring environment, reducing the amount of data storage and reducing hard disk storage space in the absence of static conditions.
3.2.2.2 Based on the user's situation, we can refer to the structure diagram of the 1#-5# room temperature and humidity sensor to determine the number of cameras used. The video signal of the camera camera can be sent to the monitoring center via the network.
The 1# engine room has 2 rows of aisles and 4 rows of server channels, so 6 cameras are used.
The 2# engine room is a one-aisle aisle, two-row server channels, and one pillar, so four cameras are used.
The 3# machine room has 2 rows of aisles and 8 rows of server channels, so 10 cameras are used.
The 4# engine room is a 2-row aisle with 3 rows of server channels, so 5 cameras are used.
The 5# room is a row of servers, so use 1 camera.

By bit rate per channel per hour of hard disk storage space 450M
That is: 26 channels X 24 hours X450M = 280G
1200G/280=4.2 days
According to the code rate = 512KBPS (the rate of image quality effect VCD effect) to calculate the space per hour per channel 225M
That is: 26 channels X24 hours X225M=140G
The 1200G hard disk can hold 26 channels of data for 8.4 days.
The host can drive up to 4T hard drives, such as increasing the hard drive to 4T can store data for about 28 days.
1T=1000G
