Description

Technical Field

[0001] The utility model belongs to the field of environmental regulation, and in particular relates to a closed space environment wireless monitoring and regulation system. Background Art

[0002] With the rapid development and gradual maturity of wireless technology, the Internet of Everything has become a daily part of people's lives. Using wireless technology to control and solve problems in daily life has brought a lot of convenience, making production and life efficient and fast. Applying wireless communication technology, the control end, motion end, and detection end are connected together to dynamically detect, control, and adjust the temperature, humidity, air pressure, wind speed, wind direction, rainfall, and light inside and outside the closed space.

[0003] Mesh network is an independently developed network technology that can use Bluetooth devices as signal relay stations to cover data in a very large physical area, and is compatible with Bluetooth 4 and 5 series protocols. Traditional Bluetooth connections are achieved by pairing one device to another, establishing a one-to-one or one-to-many micro-network relationship. Mesh network enables devices to achieve many-to-many relationships. Each device node in the Mesh network can send and receive information. As long as there is a device connected to the gateway, the information can be relayed between nodes, allowing the message to be transmitted to a location farther than the normal transmission distance of radio waves. In this way, Mesh networks can be distributed in manufacturing plants, office buildings, shopping malls, business parks and wider scenarios, providing more stable control solutions for lighting equipment, industrial automation equipment, security cameras, smoke detectors and environmental sensors.

[0004] Although the Mesh network is a breakthrough in connecting the control end, motion end, and detection end, the communication methods of the detection terminal include UART, I2C, SPI, CAN, RS-485, RS-232, etc., and the motion end has 4-20ma current drive and other methods in addition to the bus communication method. How to conveniently organize existing devices with different control methods into a Mesh network, and how to upload local information in the Mesh network to the cloud platform to achieve interconnected control are issues that need to be urgently addressed.
