[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Embodiment 1

[0019] like Figure 1 and Figure 2 As shown, a remote monitoring device for fire extinguishing gas cylinders proposed by the utility model includes a machine cavity 1, a fire extinguisher bottle 3 is installed inside the machine cavity 1, a fire extinguisher bottle valve 4 is installed on the upper end of the fire extinguisher bottle 3, the fire extinguisher valve 4 is used to control the fire extinguisher, and is connected to a control host 8, a pressure signal switch 2 is installed on one side of the fire extinguisher bottle valve 4, the pressure signal switch 2 is used to perform pressure detection, a smoke detector 12 and a flame detector 11 are installed on the upper end of the machine cavity 1, the smoke detector 12 and the flame detector 11 are used to detect smoke and fire respectively, an audible and visual alarm 13 is installed on one side of the machine cavity 1, and the audible and visual alarm 13 is activated when the smoke detector 12 and the flame detector 11 are triggered together, a control host 8 is installed on the upper end of the outside of the machine cavity 1, the control host 18 is used to control the overall monitoring device, and the control host 8 is connected to a signal antenna 10 upward, and the signal antenna 10 is used to receive signals.

[0020] Furthermore, the control host 8 is connected to the outside of the cavity with a backup power supply 7 and a main power supply 6, and the main power supply 6 and the backup power supply 7 are used to provide power to the control host.

[0021] Furthermore, the control host 8 is connected with wires in the cavity, and the wires are connected to the sound and light alarm 13 through the smoke detector 12 and the flame detector 11. When the smoke detector 12 and the flame detector 11 are triggered together, the sound and light alarm 13 is started.

[0022] Furthermore, an open area 9 is provided at the upper end of the control host 8, and the signal antenna 10 extends upward from the open area 9, so that the open area facilitates the signal antenna 10 to receive signals.

[0023] Furthermore, oval grooves are evenly arranged on the fire extinguisher bottle valve 4, and multiple groups of heating wires 5 are arranged in the oval grooves.

[0024] The working principle of the remote monitoring device for fire extinguishing gas cylinders based on Example 1 is: when the pressure signaler feeds back that the working pressure of the fire extinguishing system gas cylinder has dropped, the remote terminal and the control host panel receive alarm signals at the same time. If the smoke detector and the flame detector do not alarm, it is judged that the gas cylinder pressure has dropped, and the staff needs to inspect or maintain the fire extinguishing system.

[0025] When the remote terminal monitor receives a fire alarm signal, the staff can remotely start the multi-functional fire control system to heat the temperature-sensitive glass bead heating wire to 79°C. The liquid inside the glass ball expands and breaks the glass ball. The fire extinguishing agent in the gas cylinder pushes out the valve core under the driving nitrogen pressure, completing the release of the fire extinguishing agent to extinguish the fire, thereby controlling the fire in the initial stage.

[0026] When the multifunctional fire control system receives a fire alarm signal, the staff presses the fire extinguishing system release button on the control host panel to heat the temperature-sensitive glass bead heating wire to 79°C. The liquid inside the glass ball expands and breaks the glass ball. The fire extinguishing agent in the gas cylinder pushes out the valve core under the driving nitrogen pressure, completing the release of the fire extinguishing agent to extinguish the fire, thereby controlling the fire at the primary stage.

[0027] When the protected area reaches the glass ball's operating temperature of 79°C, the liquid inside the glass ball expands and causes the glass ball to rupture. The fire extinguishing agent in the gas cylinder pushes the valve core out under the driving nitrogen pressure, completing the release of the fire extinguishing agent to extinguish the fire.

[0028] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
