Background

Heptafluoropropane (HFC-227ea/FM200) is a clean gas chemical fire extinguishing agent which mainly uses chemical fire extinguishing and has physical fire extinguishing function; is often used in important places such as machine rooms and the like. The heptafluoropropane fire extinguishing agent is automatically released and has a certain risk of mistaken leakage, and the heptafluoropropane is a colorless and tasteless gas with toxicity and cannot be detected by people when mistaken leakage occurs. Because the machine room is a closed space, when operating personnel enter an environment with the concentration of heptafluoropropane over 10 percent, discomfort can occur, and the machine room is life-threatening for a long time. However, the power grid dispatching automation machine room is not equipped with a corresponding device for detecting heptafluoropropane gas in real time.

Further, the mobile terminal of the machine room operation and maintenance personnel is a smart phone, a notebook computer and a tablet computer.

Through the design scheme, the invention can bring the following beneficial effects:

1. the invention fills the blank of the heptafluoropropane gas leakage alarm in the existing power grid dispatching automation machine room.

2. The safety is high: the operation and maintenance personnel can be warned at the beginning of the leakage of the heptafluoropropane gas, and can deal with the fault at the first time; meanwhile, people can be prevented from entering the machine room with heptafluoropropane leakage by mistake.

3. The manufacturing is simple: the heptafluoropropane alarm provided by the invention is based on the existing patrol robot in a machine room, and the power supply can be obtained more easily.

4. The cost is saved: the concentration of the heptafluoropropane gas in the machine room is detected while the machine room is patrolled by the existing patrol robot in the machine room, so that alarms are mounted at all positions of the machine room, and the cost is greatly saved.

Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be understood that the scope of the claimed subject matter is not limited to the embodiments described below, but encompasses any technique capable of being practiced without departing from the spirit of the claimed subject matter and that no detailed description of well-known methods, procedures, flows, components, and circuits has been presented in order not to obscure the subject matter of the present disclosure.

As shown in fig. 1 and fig. 2, a heptafluoropropane alarm installed on inspection robot, inspection robot has had automatic inspection robot for the computer lab, inspection robot and computer lab fortune dimension personnel's mobile terminal radio communication are connected, computer lab fortune dimension personnel's mobile terminal is smart mobile phone, notebook computer and panel computer, and computer lab fortune dimension personnel's mobile terminal disposes inspection robot terminal software program, its characterized in that: the heptafluoropropane alarm comprises a gas pipeline 2, a gas pump 3, a heptafluoropropane sensor 4, a singlechip 5, a loudspeaker 6 and an alarm lamp 7.

The gas pipeline 2 is tightly attached to the outer wall of the chassis shell 1 of the inspection robot and welded to the outer wall of the chassis shell 1 of the inspection robot, and the air pump 3 is installed at one end of the gas pipeline 2 so as to suck air in the machine room into the gas pipeline 2.

The probe of the heptafluoropropane sensor 4 is arranged in the middle of the inside of the gas pipeline 2, the heptafluoropropane sensor 4 is connected with the single chip microcomputer 5, and the heptafluoropropane sensor 4 is used for transmitting the concentration data of the heptafluoropropane gas detected by the heptafluoropropane sensor 4 to the single chip microcomputer 5; as a preferable example of the present invention, the heptafluoropropane sensor 4 employs a LY3400-C3HF7 heptafluoropropane sensor; the singlechip 5 adopts a Siemens S7-200 singlechip. The gas detecting member is installed at the lower part of the inspection robot in the present invention because the molecular weight of heptafluoropropane is large and heavier than that of air, and the heptafluoropropane gas is more rapidly detected by the heptafluoropropane sensor 4 installed at the lower part.

The single chip microcomputer 5 is installed inside a chassis of the inspection robot, the single chip microcomputer 5 is connected with a main controller of the inspection robot, and the single chip microcomputer 5 is used for sending data processed by the single chip microcomputer 5 to the main controller of the inspection robot.

Speaker 6 and alarm lamp 7 all weld on the outer wall of inspection robot chassis shell 1, and speaker 6 and alarm lamp 7 all link to each other with singlechip 5.

The heptafluoropropane alarm provided by the invention is based on the existing automatic patrol robot in a machine room, and the automatic patrol robot patrols three times every day according to a set route, so that the heptafluoropropane gas can be measured at any position of the machine room. The air pump 3 of the heptafluoropropane alarm starts to operate when the inspection robot inspects the air, and air in the machine room is pumped into the air pipeline 2. Once the heptafluoropropane leaks and the concentration reaches the preset concentration of 10%, the heptafluoropropane sensor 4 sends an electric signal to the single chip microcomputer 5. The singlechip 5 transmits the electric signal to the loudspeaker 6 and the alarm lamp 7, and the heptafluoropropane alarm gives out sound-light alarm. Meanwhile, the single chip microcomputer 5 also transmits the electric signal to a main controller of the inspection robot, a software part of the main controller of the inspection robot is provided with a heptafluoropropane leakage alarm strategy, when the main controller of the inspection robot receives the electric signal, a heptafluoropropane leakage message is transmitted to an inspection robot terminal software program, the inspection robot terminal software program is configured in a mobile terminal of a machine room operation and maintenance worker, after the inspection robot terminal software program sends alarm information through the mobile terminal carried by the machine room operation and maintenance worker, the machine room operation and maintenance worker can sense the leakage of heptafluoropropane gas in advance, and the defect of the heptafluoropropane fire extinguisher is treated under the condition that the safety of the machine room operation and maintenance worker is guaranteed.
