Description

Technical Field

[0001] The present application relates to the technical field of organic volatile gas monitoring, and in particular to an organic volatile gas monitoring device with LoRa wireless communication. Background Art

[0002] Organic volatile gases refer to volatile organic compounds. According to the definition of the World Health Organization, compounds with a boiling point of 50°C-250°C under normal conditions are volatile organic compounds; however, the definition in the environmental sense refers to a class of active volatile organic compounds, that is, the class of volatile organic compounds that can cause harm. With the rapid development of industry, the monitoring and management of organic volatile gases have become increasingly important. Traditional organic volatile gas monitoring equipment mainly relies on wireless communication technologies such as wired transmission and Wi-Fi. However, these technologies have some obvious disadvantages. For example, wired transmission requires laying cables, which is costly and difficult to maintain; and wireless communication technologies such as Wi-Fi consume large power and are not suitable for long-term and large-scale monitoring. Therefore, a LoRa wireless communication organic volatile gas monitoring device is proposed to solve the problems described in the above background technology.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0006] A LoRa wireless communication organic volatile gas monitoring device comprises a front-end monitoring device and a network device, wherein the front-end monitoring device internally comprises a PID sensor, a FID sensor, a methane sensor, a CO sensor, a CO2 sensor, a PM2.5 sensor, a PM10 sensor, a SO2 sensor and a humidity sensor, and the network device internally comprises a LoRa gateway module, an IP gateway module and a control module.

[0007] Preferably, the network device terminal is respectively provided with a government remote monitoring unit, a park monitoring unit and an enterprise monitoring unit.

[0008] Preferably, the front-end monitoring device is connected to the network device via Lora network data, and the front-end monitoring device is connected to the network device via IP network data.

[0009] Preferably, the IP network data connects the government remote monitoring unit, the park monitoring unit and the enterprise monitoring unit to the network device in sequence.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] By designing this device, when monitoring organic volatile gases, the organic gas content in the area is monitored through the PID sensor, FID sensor, methane sensor, CO sensor, CO2 sensor, PM2.5 sensor, PM10 sensor, SO2 sensor and humidity sensor in the front-end monitoring equipment, and then the monitored data is processed through Lora network data, IP network data and network equipment, and finally transmitted to the government remote supervision unit, the park supervision unit and the enterprise supervision unit respectively, so that emergency processing can be carried out on the monitoring results later. Compared with the existing technology, this design can monitor multiple gas components at the same time through the organic volatile gas sensor array inside the front-end monitoring equipment, and at the same time, the LoRa gateway module in the network equipment can realize long-distance, low-power data transmission, so that a stable communication connection can be maintained even in a complex environment.
