Hereinafter, the working relationship of the central monitoring system for the leakage of dangerous substances of the present invention consisting of the alarm means 10 , the terminal means 20 and the central control center 30 will be described.

First, the leak sensor 11 and the gas sensor 14 of the alarm means 10 are installed in the dangerous facility to continuously detect the leakage of dangerous substances, and the alarm means 10 to detect the dangerous substances in accordance with a preset period. However, when the leakage of dangerous substances is detected, the amount or concentration of the dangerous substances is immediately transmitted to the control unit 102 together with an alarm signal.

When the control unit 102 of the warning means 10 receives the dangerous material leakage information from the sensors, it is determined whether the leakage amount or the concentration of the emission gas exceeds a preset standard. The above 'standard' is set in consideration of the risk caused by the leakage of dangerous substances, but the minimum amount or concentration of leakage that requires immediate action due to the expectation of casualties, explosion or fire is set as the above standard.

If the determination result exceeds the above criteria, ① an alarm is issued to the site through the leak alarm 12 and the gas alarm 15, ② the blocking unit 103 or the ventilation unit 109 is driven, and ③ the terminal The means 20 and the central control center 30 transmits a dangerous substance outflow status message. At this time, the dangerous material leakage situation message includes the name, location, the date and time of detection of the dangerous material leakage, the amount or concentration of the leaked hazardous material, countermeasures, and the wind direction and speed of the site.

On the other hand, if the degree of leakage of dangerous substances does not meet the above criteria as a result of the determination, after executing the measures ① and ③, a response action instruction from a person concerned with dangerous substances or the central control center 30 is awaited.

The central control center 30, which has received the dangerous substance leakage situation from the warning means 10, grasps the location of the terminal means for the person concerned, and controls the terminal means for the person concerned in the first area 51 located closest to the dangerous facility. Two persons in possession of dangerous goods are selected and instructed through the terminal means for those concerned to go to the dangerous facility. At this time, if there is no person concerned with dangerous goods in the first area 51, the second area 52 and the third area 53 are searched for whether there is a person with a terminal means for the concerned person.

The first zone 51 is mainly set in the area where direct damage is concerned when a hazardous material leakage accident of a hazardous facility occurs, and the second zone 52 is mainly set in the area where direct damage is not expected but indirect damage is concerned, The third zone 53 is mainly set as a safety zone.

A person in possession of a terminal means for a person in possession of a terminal means for a person who has received a dispatch command from the central control center 30 is urgently dispatched to a dangerous facility where a dangerous material leakage accident has occurred, but before approaching the dangerous facility within a predetermined distance, the terminal means for the person concerned When the sensor and camera provided in the detection unit 28 of the detection unit 28 are driven and the dangerous facility is approached, the detection unit 28 measures the concentration of the hazardous material gas or captures an image of the hazardous facility, so that the control unit 22 can control it in real time. It is transmitted to the central control center 30 and simultaneously output to the display 24 so that the person concerned with the dangerous material can check it, and at this time, an alarm sound can be output together to draw the attention of the person concerned with the dangerous material.

The central control center 30, which has received the detection result of the leakage of dangerous substances from the two terminal means for the concerned person, compares the detection result of the warning means 10 with the detection result of the two terminal means for the person concerned. At this time, if two or more detection results among the three detection results indicate a dangerous substance leak, it is determined as a dangerous substance leak and the follow-up countermeasures are executed. In addition, if only the detection result of the alarm means 10 shows a dangerous substance outflow and the detection result of the two related terminal means is not a dangerous substance outflow, it is determined as an error of the warning means 10, and the alarm means 10 The measures taken by the user are returned to the original state, and the person in charge of dangerous goods is instructed to check the alarm means 10 through the terminal means for the person concerned.

The countermeasures of the central control center 30 according to the leakage of dangerous substances are: ① For all workers in hazardous facilities, the situation propagation through the terminal means for the person concerned and the terminal means for general use, the evacuation instruction and the location tracking of the entire terminal means 20 start, ② The operation of the blocking unit 103 and the ventilation unit 109 that are not driven through the control unit 102 of the alarm means 10 ③ The entire terminal by taking into account the wind direction and wind speed of the site and predicting the spread range of the dangerous substance gas by time Propagation of the evacuation location to the means (20) ④ Instructing the emergency recovery team consisting of maintenance personnel to recover the broken or damaged dangerous facilities through the terminal means for the person concerned, ⑤ Estimation of the dangerous substance leakage situation message and dangerous substance gas by time Directly report the spread of the spread to the local fire department and the civil defense department of the local government or direct it to report it through the general terminal means, ⑥ By identifying the evacuation status of workers from the change in the location of the terminal means for the concerned person and the terminal means for general use, It urges workers whose evacuation is delayed to evacuate promptly, grasps the emergency recovery team's dispatch situation, and maintains the focus of the image captured by the camera of the terminal means for personnel in possession of the emergency recovery team in a fixed state for more than a predetermined time. In this case, it warns of the danger of poisoning due to poisonous gas, etc., and if there is no change despite the warning, it instructs through general terminal means to dispatch a rescue team to the relevant location. In this case, the predetermined time is a time set in advance in consideration of the harmfulness of the hazardous gas managed in the hazardous facility. In addition, even when the terminal means 20 of the worker who has received the evacuation instruction does not change the position for more than a predetermined time in the first zone 51 or the second zone 52, the terminal means 20 is promptly provided to the worker. It transmits an alarm sound to inform the user to evacuate, and if there is no change in location despite the alarm sound, it is judged that the evacuation has failed and instructs the rescue team to be dispatched to the corresponding location through other general terminal means.

In addition, if the leakage of dangerous substances is first detected by the terminal means for the person concerned, one terminal means for the person concerned is additionally dispatched except for the terminal means for the person concerned that has detected the leakage of the dangerous material to check whether the leakage of the dangerous material is present, In the rest of the procedure, situation propagation and countermeasures are executed according to the same procedure as in the case where the leakage of dangerous substances is detected by the warning means (10). However, when it is determined that the degree of leakage of dangerous substances is higher than the above standard and it is necessary to drive the blocking unit 103 and the ventilation unit 109, the control unit 102 of the alarm means 10 according to the instruction of the central control center 30 is run
