Confined space operation system and method

Abstract

The present invention provides a restricted space operation system and method, wherein the restricted space operation system includes: a positioning beacon, a positioning label, a warning sign, a personnel label, a base station, and a control center; the positioning beacon is located in the Near the power supply equipment in the confined space, the positioning label is combined with the warning sign, when the warning sign enters the confined space, the scanning range of the positioning label covers the limited space, the The positioning tag receives the induction signal sent by the positioning beacon. The personnel tag is worn by the personnel entering the confined space. The personnel tag stores personnel identity information. remote communication. The invention can remotely monitor the operation situation in real time, and is convenient for the safety management of the operation. At the same time, it is beneficial to realize paperless operation, improve efficiency for chemical plants, and carry out intelligent chemical operations.

Description

technical field [0001] The invention relates to the technical field of production safety, in particular to a system and method for operating in a confined space. Background technique [0002] For the sake of safety, chemical factories will require the method of cutting off the power supply of electrical equipment, locking and hanging warning signs when working in confined spaces. In the existing method, when a chemical plant is operating in a confined space, the pipeline connected to the confined space that may endanger the safe operation should be isolated by inserting a blind plate or removing a section of the pipeline; there is no electrical equipment in the confined space. Stop running and effectively cut off the power supply, lock the power switch and hang a warning sign. [0003] However, in the actual operation process, the person in charge and the manager of the chemical plant cannot know whether the power supply of the electrical equipment in the confined space has...

Problems solved by technology

[0003] However, in the actual operation process, the person in charge and the manager of the chemical plant cannot know whether the power supply of the electrical equipment in the confined space has been cut off and whether it is safe

There may be human negligence or employee laziness, causing safety accidents

Moreover, the process of applying for this type of confined space operation is cumbersome; after the task is assigned, it cannot be transferred to each person in charge as quickly as possible; in the operation process, the content of the current operation cannot be uploaded in paper form
