the alarm browsing module automatically fills alarm information into an alarm table by the system when the measured value is higher than the alarm set value, and carries out alarm flashing on a screen by an analog alarm lamp;
and the alarm linkage module immediately starts an audible and visual alarm on site when the monitored temperature and gas concentration exceed the preset early warning or fire alarm occurs, and reminds workers that temperature abnormal points or gas abnormal and smoke abnormal exist in the absorption tower.
8. The system for monitoring the safe operation of the absorption tower based on the full-process monitoring of the operation as claimed in claim 1, wherein the restricted space management module is used for monitoring personnel entering the restricted space, and further comprises a video monitoring module, and the video monitoring module is used for monitoring the inside and outside areas of the absorption tower in real time.
9. The system for monitoring the safe operation of the absorption tower based on the full-process monitoring of the operation as claimed in claim 1, wherein the working process of the face recognition module comprises the following specific steps:
firstly, recording the archive information of names, photos, telephones and the like of constructors;
secondly, capturing a face image, recording the time of all people entering and leaving the absorption tower, and automatically generating a report of constructors entering and leaving the absorption tower area;
and finally, for personnel who do not leave the field for more than 12 hours, the system automatically gives an alarm to prompt, and the personnel are prevented from not withdrawing from the inside of the absorption tower when in shutdown.
10. The system for monitoring the safe operation of the absorption tower based on the whole operation flow monitoring as claimed in claim 1, wherein the violation snapshot module is based on an artificial intelligence computer vision analysis technology, can automatically identify the wearing state of a safety helmet of a construction worker, and outputs alarm information and takes a violation image in a snapshot manner when the safety helmet worker is not worn in a detection area.
