In some cases, it may be difficult to directly grasp the status of the construction due to the concurrent use of multiple other workplaces, or the increase in the number of holidays from the viewpoint of the working environment. Therefore, in order to make up for this shortage, security personnel (guardmen) are stationed at all times to deal with it. With various measuring instruments installed on site,
For example, it is always necessary to monitor for safety management whether or not the preset condition range is exceeded. In addition, construction machines (pumps) and the like may not operate normally due to unexpected failures such as interruption of power supply due to disconnection, so that it is necessary to monitor by a specialized engineer or security personnel in preparation for such a situation.

However, even if security personnel are deployed 24 hours a day in preparation for the absence of a specialized engineer, if the measuring instrument shows a numerical abnormality or an accident occurs, it is necessary to take measures against it. Professional knowledge is often required, and security personnel who do not have specialized knowledge cannot immediately take appropriate measures.
The accident may spread. Furthermore, as a result, the recovery can be time-consuming and costly.

Therefore, the present invention has been proposed in view of the above-mentioned problems of the prior art, and an object thereof is to provide a monitoring device for construction management and monitoring equipment or security equipment arranged in each work place. A signal from an alarm device or an alarm device is sent via an automatic notification device and a public telephone line to a professional engineer carrying a communication device or a construction manager to report the emergency situation directly, and appropriate measures are taken to prevent a disaster. It provides a safety management system that prevents the occurrence of accidents and prevents the spread of accidents.
