Embodiment

[0044] Taking the on-site sensor as a temperature sensor and the hazardous chemical solution as an alkaline hydrogen peroxide solution as an example, the embodiment will be described.

[0045]The embedded development board collects and monitors the temperature information of three positions in the alkaline hydrogen peroxide solution container, and inputs it to the embedded development board through the GPIO port. The actual physical temperature data is obtained by calibrating the original signal of the temperature sensor data and stored. In the storage module, it is sent to the IoT cloud platform at a certain frequency at the same time, and the current temperature status is judged in real time through the abnormal temperature thresholds of the three positions of the alkaline hydrogen peroxide solution set by the user, and the abnormal status exceeding the threshold is also sent To the IoT cloud platform. The monitoring personnel of the alkaline hydrogen peroxide solution can c...

Abstract

The invention relates to a hazardous chemical solution safety early warning and remote monitoring system and method based on the Internet of Things. The system comprises an embedded development board,a wireless network card, a field sensor, a storage module and a power module. The method comprises the steps that: the field sensor collects field data of a hazardous chemical solution in real time and sends the field data to the embedded development board, and the embedded development board sends the field data to a target monitoring terminal through an Internet of Things cloud platform; an abnormal field data threshold value of the hazardous chemical substance solution is set, and if field data exceeds a threshold value, an abnormal state alarm signal is generated through the embedded development board and sent to the target monitoring terminal through an Internet of Things cloud platform. The hazardous chemical substance safety monitoring personnel can remotely check the state of the monitored hazardous chemical substance and the state change curve condition anytime and anywhere through the monitoring terminal of the hazardous chemical substance safety monitoring personnel, the Internet of Things platform can actively send safety early warning prompts to the monitoring terminal of the safety monitoring personnel according to the self-defined early warning threshold value; and the time is saved, efficiency is high, and the monitoring effect is good.

Description

technical field [0001] The invention relates to the field of hazardous chemical solution monitoring, in particular to a remote monitoring system and method for hazardous chemical solution safety early warning based on the Internet of Things. Background technique [0002] Hazardous chemicals refer to chemicals that are flammable, explosive, poisonous, harmful, and radioactive, and are likely to cause casualties and property damage during transportation, loading, unloading, and storage, and require special protection. Because of its particularity and danger, the monitoring of its safety status is also extremely important. According to the characteristics of different hazardous chemicals, some need to monitor physical quantity data such as internal temperature or pressure, and some also need to cooperate with the monitoring of peripheral environmental status information, such as temperature, humidity, concentration, etc. The monitoring conditions for different hazardous chemic...
