Problems solved by technology

[0005] However, the above-mentioned wireless gas detection and alarm system still has the following disadvantages. After a long time of use, due to the time interval, it is easy to cause inaccurate gas detection data
At the same time, special personnel are set up on site for management, and the data detected by the gas detection unit are recorded in traditional written records, which is not conducive to the real-time monitoring of the overall safety supervision status of the site, and the alarm is not timely when the gas detection is abnormal, and it cannot be divided according to specific situations. alert level

Embodiment 1

[0050] Embodiment one: if figure 1 As shown, it is only one of the embodiments of the present invention, a method for detecting gas in a confined space of a nuclear power site, comprising the following steps:

[0051] S1: When an operator enters the confined space to work, place the gas detection robot in the confined space;

[0052] When an operator needs to enter the restricted space to work, before the operator enters the restricted space, place the gas detection robot in the restricted space, and let the gas detection robot perform preliminary detection, mainly to detect whether the air in the restricted space is qualified, Avoid danger when workers enter confined spaces.

[0053] A gas detection robot is a machine with a displacement function and a gas detection instrument.

[0054]Of course, before step S1 is executed, the debugging of the gas detection robot is mainly to debug the gas detector and the displacement function of the robot, so as to ensure the accuracy of...

Embodiment 2

[0080] Embodiment two: if figure 2 As shown, it is only one of the embodiments of the present invention, and the present invention also provides a gas detection system in a confined space at a nuclear power site, which includes:

[0081] Gas detection module;

[0082] displacement module;

[0083] Gas data acquisition module;

[0084] sending module;

[0085] Master control module;

[0086] The first judgment module;

[0087] Prompt module;

[0088] The second judgment module;

[0089] Alarm module;

[0090] The third judgment module;

[0091] computing module;

[0092] notification module;

[0093] When an operator enters the restricted space to work, place the gas detection module in the restricted space, drive the gas detection module to move in the restricted space through the displacement module, and obtain the gas data at the gas detection module in real time through the gas data acquisition module. And send it to the master control module outside the restric...

Abstract

The invention provides a nuclear power site confined space gas detection method and system, which relate to the technical field of safety construction. The method comprises the following steps of S1, placing a robot in a confined space during operation, S2, moving the robot moves in the confined space, S3, acquiring gas data at the robot in real time, S4, judging whether the safety degree of the gas data is higher than a first threshold value or not, and if yes, prompting that operation is allowed, S5, judging whether the safety degree of the gas data is lower than a second threshold value or not, if yes, starting an alarm to prompt evacuation, and executing S6, or otherwise, executing S7, S6, judging whether the safety degree of the gas data is lower than a third threshold value or not, if yes, generating a dangerous area, and sending an evacuation message to workers in the dangerous area, and S7, completing operation, and recycling the robot. The system is simple and convenient, does not need manpower management, saves labor cost, is high in intelligent degree, is high in gas detection precision, is good in safety, carries out grading alarm, and guarantees timely and efficient alarm.

Description

technical field [0001] The invention relates to the technical field of safe construction, [0002] In particular, the present invention relates to a gas detection method and system in a confined space of a nuclear power site. Background technique [0003] During the construction of a nuclear power plant, there are many confined spaces on the construction site. Confined space refers to the interior of various equipment in the factory (furnace, tower kettle, tank, warehouse, pool, tank car, pipe, flue, etc.) and the tunnel, sewer, ditch, pit, well, pool of the city (including the factory) , culverts, valve rooms, sewage treatment facilities and other closed and semi-closed facilities and places (cabins, underground concealed projects, airtight containers, facilities that have not been used for a long time or places with poor ventilation, etc.), as well as wells and cellars for storing materials in rural areas, etc. . Due to poor natural ventilation in such places, it is eas...
