Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] The embodiment of the present invention discloses a combustible gas detection system, which has simplified buttons and multiple functions, and is suitable for combustible gas detection in a family room, and records are only made when the low-report threshold or high-report threshold is exceeded, which saves storage space. In addition, when an explosion of flammable gas is detected and a fire occurs, the fire detector can be used to detect it in time, an...

Abstract

The present invention discloses a combustible gas detection system, comprising a background controller, a combustible gas detector, a fire detector, a fire extinguishing robot, an exhaust fan, a solenoid valve and an alarm device. The combustible gas detector comprises an explosion-proof shell, a charging interface, a power jack and a display screen; a power indicator light, a fault indicator light, a high report indicator light and a low report indicator light located at both sides of the display screen; an on/off key, an increase key, a decrease key and a query key at the bottom of the display screen; detection parts symmetrically disposed on the explosion-proof shell; a circuit board fixed inside the explosion-proof shell; and a power supply module, a communication module, a control module and a recording module on the circuit board. The control module comprises a self-test unit, a temperature compensation unit, an A/D conversion unit, a time detection unit, a first judgment unit, a second judgment unit and a control unit. With simplified keys, the combustible gas detection system is convenient to operate and is able to detect combustible gas and also deal with harsh conditions, thereby achieving high practicability.

Description

technical field [0001] The invention relates to the technical field of technical detectors, and more specifically relates to a combustible gas detection system. Background technique [0002] For oil refineries, drilling platforms, compressor stations, fuel supply stations, chemical plants, liquefied gas storage devices and other places, fire prevention is very important; as long as a fire occurs, it is likely to cause great danger to the entire production area. Among them, the fire caused by combustible gas is one of the more serious fire hazards. Therefore, combustible gas detectors used in these places are very important. [0003] At present, there are many forms of combustible gas detectors, such as point combustible gas detectors, infrared combustible gas detectors, etc. These combustible gas detectors mainly use gas sensors to chemically react with nearby combustible gases, thereby Cause the resistance characteristic of the gas sensor to change, and determine the conce...
