The invention provides a civil engineering construction fire operation management and control system and method, aiming at realizing centralized management of fire operation and improving management efficiency of fire operation.
The technical scheme of the civil engineering construction fire-working management and control system is as follows:
a civil engineering construction fire-working management and control system comprises a controller, a fire receiving hopper and an auxiliary module; the fire receiving hopper comprises a collecting device and a containing device arranged at the lower part of the collecting device; a discharge hole is formed in the bottom surface of the collecting device; the bottom surface of the collecting device is inclined towards the discharge hole; the auxiliary module comprises a welding machine detector for detecting the start and stop of a welding machine, a temperature sensor and a movable baffle; the temperature sensor and the movable baffle are arranged at the discharge port; the welding machine detector, the temperature sensor and the movable baffle are in signal connection with the controller; the fire receiving hoppers and the auxiliary modules are arranged in a one-to-one correspondence mode.
When the civil engineering construction fire-working management and control system is used, the welding machine detector is used for detecting the start and stop of a welding machine, and the temperature sensor detects the temperature of the discharge port in real time; the welding machine detector and the movable baffle are linked through the controller, when the welding machine detector detects that the welding machine is started, the movable baffle is closed, and when the welding machine detector detects that the welding machine is closed, the movable baffle is opened.
If connect the fire fill to be in the operation scope of starting a fire, then when the welding machine started, the welding slag dropped to collection device in and slided to discharge gate department, and temperature sensor detects out discharge gate temperature and risees, and when the welding machine was closed, adjustable fender opened, and the welding slag dropped to collection device from the discharge gate, and temperature sensor detects out the discharge gate temperature and reduces.
If the welding wire bucket is outside the operation scope of starting a fire, then the welding slag can't drop to the discharge gate department, no matter the welding machine starts or stops, temperature sensor can't detect the change of temperature.
Therefore, the person seeing the fire can judge whether the fire receiving hopper is in the fire working range through the temperature sensor, and therefore control of the fire working is achieved. When the temperature sensor can detect that the temperature of the discharge port rises or falls along with the start and stop of the welding machine, the operation of igniting is normal, and when the temperature sensor cannot detect that the temperature of the discharge port rises or falls along with the start and stop of the welding machine, the operation of igniting is abnormal.

In the process of the fire operation, the dropped welding slag is likely to have the conditions of small quantity and small volume, so that the temperature sensor cannot be contacted with the welding slag, and the detection of the temperature is influenced. After the temperature sensor and the movable baffle are set to be of an integrated structure, the temperature of the welding slag can be conducted to the temperature sensor through the movable baffle. Thus, even if the amount of the slag is small and the volume is small, the temperature sensor can detect the change of the temperature, and the judgment of the normality of the firing work is not influenced.

when the welding machine is started or stopped, the temperature sensor cannot detect the temperature change, and the fire receiving hopper is out of the fire working range, so that the fire working is abnormal;
s6, when the fire operation is abnormal, fire operation managers go to the site for management;
and S7, returning the fire receiving hopper and the auxiliary module by a fire operation constructor after the fire operation is finished.
