Dynamic ring detection system

一.Program background

It is used in computer rooms in various industries such as government, electric power, telecommunications, medical care, railways, military, enterprises, education, and the Internet to provide support for various types of business. The computer room is composed of key equipment such as computers, servers, network equipment, and storage, as well as infrastructure such as power supply systems, refrigeration systems, cabinet systems, fire protection systems, and monitoring systems. It is the core department of these units. This solution aims at the hidden safety hazards in the operation and maintenance of the computer room, and centrally monitors and manages the power, environment, network, security, etc., so as to improve the operation and maintenance efficiency and ensure the safety of the computer room.

二．Functional Requirements

• Temperature and humidity monitoring, environmental temperature and humidity monitoring and control, to ensure that the temperature and humidity of the environment can ensure that the equipment operates in the optimal environment, the temperature detection of the equipment, when the temperature of the equipment is abnormal, it is necessary to alarm in time.
• For water leakage detection, the equipment in the computer room is relatively precise and expensive, and it is necessary to detect whether there is water leakage in the computer room in real time
• Precise air-conditioning detection, air-conditioning running state, remote switch machine.
• Ordinary air conditioning detection, running state, including return air temperature, supply air temperature, air conditioning mode, power on/off state, automatic start when incoming calls and other functions.
• Monitoring of alarm video, when an abnormality occurs in a certain place in the computer room, alarm video is sent in real time.
• The monitoring of the particulate matter in the computer room, the particulate matter in the computer room is detected, and the alarm is given in time when the particulate matter is abnormal.
• UPS power detection in the computer room, use infrared to detect whether the battery is hot.

三.Feature Design

There are three main components of this program, wireless transmission, sensors, and IoT management platform.

• Wireless transmission

Facing the large-scale sensor data transmission of dynamic ring detection, our company's long-distance wireless transmission technology is used to transfer the data of various types of sensors to the dynamic ring monitoring platform. Our wireless technology uses a combination of LORA, 2G/3G/4G/5G/CAT1 (mobile network) and Ethernet. Use LORA locally to transmit sensor data to the gateway, which in turn transmits the data to the platform via a mobile network or Ethernet.。

• Sensor

Our company has obtained many patents on the research and development and application of TOF, temperature and humidity, and gas sensors. In this scenario in the computer room, a variety of sensors are used to monitor the environment.

• Management platform

  The management platform can carry out a detailed management of the equipment. It can display real-time data in real time, save data, and find historical data.

四.Detailed introduction of key products

4.1Embedded dynamic monitoring host

• Product Description       

The embedded dynamic monitoring host is a 24-hour real-time monitoring multi-functional monitoring host specially developed by our company for the computer room environment. The host can connect all our RS485/LORA transmitters (temperature, humidity, water immersion, power failure, smoke, infrared, noise, air quality) to the monitoring host through the RS485/LORA wireless interface, and Upload the data to the cloud platform provided by our company or the customer's own server in real time. The device supports 2G/3G/4G/5G, Ethernet, RS485 wired and other methods to upload data, and users can choose the corresponding sub-model products according to actual use needs.

The device has a built-in embedded WEB server, without opening the cabinet door, you can directly log in to the WEB page through the remote, setting parameters more safely and conveniently. The size of the equipment adopts rack-type design, 1U size, occupies small space, and is convenient and quick to install. Using metal shell, dustproof, anti-static, anti-interference ability is strong.

The device can use a variety of alarm methods, providing a complete alarm method, SMS, sound and light, telephone, email, APP

Prompt alarm, when the node alarms, the main page will display the alarm channel in turn, and the safety alarm can be set. When the set time is reached, the system will automatically display the alarm channel.

Automatically send the corresponding SMS to the bound mobile phone number. The device has its own voltage detection, which can be used for city power failure alarm. Switch detection can be external

Connect to switch signals such as access control. The device has the function of automatically caching data when power off, automatically uploading data when incoming calls, built-in data

Store up to 5.2 million records of information.

It is specially designed for computer network room, communication room, battery pack room, etc.
