Abstract

The invention discloses a liquid ammonia leakage alarm system used for safety production accident potential monitoring. The system comprises concentration sensors, image acquisition devices, a gatewayand a remote server, wherein each concentration sensor is arranged at a liquid ammonia storage barrel and is used for detecting the ammonia concentration of the liquid ammonia storage barrel; each image acquisition device is arranged at the corresponding liquid ammonia storage barrel and is used for carrying out image shooting on the liquid ammonia storage barrel; the gateway is respectively connected to each concentration sensor and each image acquisition device; the remote server is connected to the gateway in order to obtain concentration data and image data which are collected by the concentration sensors and the image acquisition devices, carrying out comprehensive processing on the concentration data and the image data which are corresponding to the same liquid ammonia storage barrel, judging whether the liquid ammonia storage barrel has leakage or not, and notifying a corresponding emergency contact through a mobile terminal according to a corresponding relation between the preset liquid ammonia storage barrel and the corresponding emergency contact when the liquid ammonia storage barrel has leakage. According to the system, whether the liquid ammonia storage barrel has leakage or not is judged, a judgment result is more accurate, and a false alarm rate is low.

Description

technical field [0001] The invention belongs to the technical field of toxic, flammable and irritating gas storage, and in particular relates to a liquid ammonia leakage alarm system used for monitoring hidden dangers of safety production accidents. Background technique [0002] Liquid ammonia is a colorless gas with a pungent smell. It is flammable and easily soluble in water. Once a leakage accident occurs, it will have a great impact on the human body and surrounding facilities. In the lightest cases, it will cause personal injury and equipment damage. In severe cases, casualties and production shutdown accidents are caused, and the consequences are disastrous. For this reason, many companies have developed some monitoring equipment to monitor liquid ammonia. At present, most liquid ammonia monitoring systems have automatic alarm capabilities. When the concentration detected by the concentration sensor exceeds the preset value, the controller generates an alarm control i...
