the terminal temperature and humidity monitoring instrument has an alarm function, and an industrial data alarm threshold value can be set through a key;

the terminal temperature and humidity monitoring instrument integrates two remote wireless communication modes of LoRa and WiFi, industrial data can be transmitted to a data fusion gateway side in real time through LoRa for fusion analysis, or the data can be transmitted to a server directly through WiFi to meet the requirements of different scenes of customers, specifically, the adopted LoRa is a LoRa spread spectrum technology working in a frequency band of 410-441 MHz, the aerial transmission rate can reach 19.2kbps, the transmitting power can reach 30dBm, the actual measurement of the transmission distance can reach 8km, the working temperature of the LoRa meets the industrial grade requirement of-40-85 ℃, and the terminal temperature and humidity monitoring instrument can stably work in a complex environment;

In the production process of the chemical plant of the embodiment, the ozone concentration and the pH value in the industrial equipment need to be monitored in real time, and the two substances need different component amounts in different temperature and humidity environments. If the ozone with the same concentration and the fixed pH value are used in different temperature and humidity environments, the qualification rate of products can be greatly reduced. Therefore, it is necessary to perform fusion analysis processing on four parameters (temperature, humidity, ozone concentration, pH value). The terminal temperature and humidity monitoring instrument in this embodiment can monitor the temperature and humidity data of the industrial equipment in real time, and report this data to the data fusion gateway through LoRa, and the data fusion gateway can collect ozone concentration and pH value in the industrial equipment that other terminal monitoring instruments reported simultaneously.

After the data fusion gateway collects the four parameters, the optimal ozone concentration and pH value of the product can be calculated according to the collected temperature and humidity data, and the calculation result is transmitted to the monitoring terminal of the client, so that the production of the product is guided. Important parameters in the fusion processing algorithm are configured through Bluetooth built in the data fusion gateway, so that the method is suitable for different scenes with different product parameter requirements. The quality of products can be greatly improved by utilizing a gateway side data fusion algorithm, so that the core competitiveness of an enterprise is improved. The work flow of the data fusion gateway in this embodiment is specifically shown in fig. 6, and includes the following steps:

b1, collecting the actual ozone concentration and the PH value in the equipment in real time by the data fusion gateway, if the relevant data of the ozone concentration and the PH value are collected, continuously inquiring and acquiring the greenhouse data of the environment where the equipment is located, and if the relevant data of the ozone concentration and the PH value are not collected, continuously collecting and acquiring the actual ozone concentration and the PH value in the equipment;

b2, if the ozone concentration and the PH value in the equipment are collected, calculating to obtain the ideal ozone concentration and the PH value by combining preset fusion processing parameters and the acquired temperature and humidity data;

and B3, comparing the ideal ozone concentration and the PH value, judging whether the actual ozone concentration and the PH value are suitable for product production, if so, reporting related industrial data and prompting that the current production environment is good by the data fusion gateway, otherwise, reporting the related industrial data and prompting that the current production environment is not suitable for product production by the data fusion gateway to give an alarm.

In step B1, the threshold of the number of acquisition times for continuously collecting and acquiring the actual ozone concentration and PH value in the device is K, and when the number of acquisition times exceeds K, the data fusion gateway reports the alarm information of the fault of the terminal detection instrument, where K is 3 in this embodiment.
