A monitoring method and controller for emergency equipment

Abstract

The invention discloses a rescue equipment monitoring method and a controller. the method comprises steps: the combustible gas concentration information at each position on the rescue equipment is acquired; according to the combustible gas concentration information at each moment, the increasing speed of the current combustible gas concentration is judged; as the gas spreads fast and certain uncertainty and sudden factors exist, the controller judges the gas concentration increasing or decreasing trend, and according to the combustible gas concentration increasing speed, the time when the rescue equipment is in a danger state is judged, and actions are made in advance. The safety control method solves the problem of safety rescue work of the rescue equipment in a dangerous environment, ongoing of the rescue can be ensured forcefully, and the controller has a simple structure and is convenient to execute.

Description

technical field [0001] The invention relates to the field of engineering machinery, and relates to a monitoring method and a controller for emergency equipment. Background technique [0002] When a flammable gas leak occurs, the common method is to stop the operation (such as shutting down the flammable gas pipeline transmission) and wait for the gas in the leakage area to dissipate. This method is not only inefficient, but also brings huge economic losses. When the operation is not stopped, combustible gas continues to leak, and neither people nor machines can get close. When emergency equipment operates in a dangerous environment (such as an environment where flammable gas leaks), there are no relevant standards and operating methods in China, and the national explosion-proof standard also excludes flammable gas leaking environments from ordinary explosion-proof standards. However, the gas concentration in the on-site environment changes rapidly, and the sensor detection ...

[0002] When a flammable gas leak occurs, the common method is to stop the operation (such as shutting down the flammable gas pipeline transmission) and wait for the gas in the leaking area to dissipate. This method is not only inefficient, but also brings huge economic losses.

When the operation is not stopped, the combustible gas will continue to leak, and neither people nor machines can get close

When emergency equipment operates in a dangerous environment (such as a flammable gas leakage environment), there are no relevant standards and operating methods in China, and the national explosion-proof standard also excludes the flammable gas leakage environment from the general explosion-proof standards

However, the gas concentration in the on-site environment changes rapidly, and the sensor detection has hysteresis. The present invention establishes a corresponding model for this phenomenon, and proposes a self-adaptive rescue equipment control method that does not stop working in a dangerous environment, and adopts an automatic control method. , to ensure that the equipment has been working in a safe environment
