In order to solve the potential safety hazard, a method of combining a fixed gas alarm device and a portable gas alarm device is generally adopted to meet the protection requirement in daily work. However, if a field gas area needs to be overhauled or constructed, construction teams work simultaneously in multiple lines, many participators exist, the related area is wide, the fixed gas alarm device cannot cover the effective operation area, the portable gas alarm device cannot be worn and used by all people, often several people share one portable gas alarm device, the personnel in the operation area are scattered, and related personnel cannot know the gas concentration condition in the operation area in time, so that hidden danger is brought to operation safety.
If a set of movable regional gas alarm device exists, the regional gas concentration is monitored in real time by being placed in a designated operation region, when an abnormality is found, regional operators can be informed of safely withdrawing in a sound-light alarm and voice prompt mode, the risk of gas poisoning of the regional operators can be reduced, and the personal safety of the operators can be ensured.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a movable region formula coal gas alarm device can be to the real-time early warning of coal gas concentration under the industrial field complex environment to ensure coal gas regional operation personnel's personal safety.
The technical scheme of the utility model:
the movable area type gas alarm device comprises a power supply module, an STM32 single chip microcomputer, a CO probe, an LED display screen, an audible and visual alarm and an operation screen; an STM32 single chip microcomputer is used as a control center, a main system frame is formed by an RS485 communication interface, a CO probe, an LED display screen and an audible and visual alarm, and the access of a plurality of CO probes is expanded in a wireless Internet of things mode to realize effective measurement of gas values in an area; the LED display screen is used for displaying the measured value of each sensor in real time and is matched with the audible and visual alarm to carry out text prompt and audible and visual alarm voice prompt.
The power supply module is responsible for the power supply of the whole system, and the 12V storage battery power supply is respectively converted into 5V, 12V and 24 power supplies required by the system through the voltage boosting, voltage reducing and voltage stabilizing modules, and is matched with related protection circuits, so that the whole power supply system of the system is safe, stable and reliable.
The main structure is provided with a push handle and a roller, and the LED display screen supporting rod is provided with a lifting mechanism so as to arrive at a field gas operation area and other emergency places and monitor the CO concentration of the field environment in real time.
The main working principle is as follows: the system is supplied with power by a 12V storage battery through a power supply conversion module and a protection module, an STM32 single chip microcomputer is responsible for calculating and processing data of a CO probe, and is connected with an LED display screen and an audible and visual alarm through an RS485 communication mode, peripheral CO detection values are displayed on the LED display screen in real time, if the CO concentration exceeds the standard, alarming and voice prompt are carried out through the audible and visual alarm, and the LED display screen is accompanied with corresponding character prompt. The system is provided with a touch screen, and relevant data of the system can be modified, such as alarm value setting, alarm modes and the like. The system can be expanded to transmit related data back to the cloud end through mobile internet of things signals to be displayed at WEB and APP ends, and remote monitoring is achieved.
The utility model has the advantages that: the movable area type gas alarm device can be rapidly deployed in a complex industrial environment, real-time detection data display is carried out in a mode of an LED large screen, and early warning can be carried out in various modes. The early warning sound emitted by the industrial acousto-optic alarm device is several times higher than that of a small alarm device, the whole operation area can be completely covered, and the striking flash lamp can enable workers in a noise area to find hidden gas hazards in time, so that the workers can evacuate safely as soon as possible, and the personal safety of the workers in the peripheral area is ensured.
The utility model discloses can be used as fixed alarm device's emergency equipment, if fixed coal gas alarm device breaks down and can not in time get rid of the problem, can in time put into use, ensure relevant personnel's personal safety.
