[0002] Most of the existing gas detection sensor devices on the market are single-function detection sensors, such as various types of carbon monoxide, carbon dioxide, oxygen and other sensors, etc. These devices mostly use 485 or network interfaces. For spaces that need to detect multiple gas indicators, multiple devices need to be installed, and each device must be connected to the control center through 485 or network lines. The disadvantage is that the wiring is very inconvenient. If new points need to be added later, the line rewiring project is huge and the cost is high. Summary of the invention

The technical solution of the present invention is implemented as follows:

[0004] An all-in-one gas sensing device with switching and POE power supply functions comprises an all-in-one sensor module, a Modbus gateway and a WIFI switching module; the all-in-one sensor module comprises a plurality of real-time measurement value detection sensors of air indicators, which are used to simultaneously detect the real-time content values ​​of a plurality of gases; the Modbus gateway is used to complete the serial port to Ethernet data conversion function; the WIFI / switching module is an integrated gigabit switching network and a high-performance embedded WIFI6 module, which complies with IEEE standards 802.11a / b / g / n / ac / ax, and the module integrates a 2.4G / 5.8G radio frequency transceiver, which is used to realize the communication between the all-in-one gas sensing device and the Internet; and also comprises a power supply module, which is used to power the all-in-one sensor module, the Modbus gateway and the WIFI switching module.

[0016] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Reference Figure 3 Most of the existing gas detection sensor devices on the market are single-function, such as various types of carbon monoxide, carbon dioxide, oxygen and other sensors, and most of these devices use 485 or network interfaces. For spaces that need to detect multiple gas indicators, multiple devices need to be installed, and each device must be connected to the control center through 485 or network lines. Wiring is very inconvenient. If new points need to be added later, the line rewiring project is huge and the cost is high.

[0018] See also Figure 1 ,This device is composed of an all-in-one sensor module, a modbus gateway, and a WIFI switch module.

[0019] Among them, the all-in-one sensor module integrates the real-time measurement values ​​of ten air indicators, including methane, oxygen, carbon monoxide, hydrogen sulfide, ammonia, ethanol, formaldehyde, carbon dioxide, temperature, and humidity. The design of using a 485 interface and concentrating multiple sensors in one device simplifies the installation and commissioning of on-site equipment compared to the traditional single sensor mode. For example, if the original site needed to detect three gases, including oxygen, carbon monoxide, and carbon dioxide, now only one new device is needed to meet the requirements.

[0020] The Modbus gateway can complete the serial port to Ethernet data conversion function; it has a variety of Modbus gateway modes and MQTTC / HTTPC IoT gateway modes, which can meet the networking functions of various serial port devices / PLCs; it has an RJ45 adaptive 10 / 100M Ethernet interface and supports a variety of working modes (TCP Server, TCP Client, UDP Server, etc.); it supports three configuration methods: configuration tool, web page, and AT command; it supports a variety of serial port protocols (RS485, RS422, RS485); it supports a variety of baud rates and flow control configurations; it supports a variety of Modbus gateways (simple protocol conversion, multi-host mode, storage gateway, configurable gateway, etc.); the external 485 interface can facilitate other devices to access the system through this device.

[0021] The WIFI / switch module is an integrated Gigabit switching network and high-performance embedded WIFI6 module. The module complies with IEEE standards 802.11a / b / g / n / ac / ax. The module integrates a 2.4G / 5.8G RF transceiver and has the characteristics of high transmission rate. It uses a dedicated high-performance 32-bit RISC CPU, supports 20 / 40MHz bandwidth in the 2.4GHz band and 20 / 40 / 80MHZ bandwidth in 5G, supports 2.4g / 5.8GHz band, supports STA / AP two working modes, and supports wireless upgrade (OTA). In order to facilitate the power supply of other devices, the switch module also adds a standard POE power supply function to meet the external connection requirements of various devices. POE power supply meets the IEEE802.3at PSE solution. Two 802.3at ports can be automatically managed without any external control. Automatically detect power supply devices (PDs) with valid signatures, determine power supply requirements according to classification, and apply power. Support for DC disconnect and external field effect transistor (FET) architectures allows designers to balance size, efficiency and solution cost needs. This provides best-in-class thermal performance and low build cost.

[0022] Compared with the existing technology, this application designs a new device, which first includes the detection of multiple conventional gases, including oxygen, carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia and other 10 kinds. It also has network switching, POE power supply, 485 expansion and other functions. After the device is deployed, it can be used as a sub-center of the deployment site (such as Figure 2 Other equipment at the deployment site, such as infrared, water immersion and other equipment, can be connected to this device first, and then the equipment data can be imported into the control center through this device, which is convenient for on-site construction and saves a lot of costs.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
