Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguisher monitoring, and in particular to an intelligent fire extinguisher monitoring device and a monitoring method. Background Art

[0002] Fire extinguishers are commonly used fire-fighting tools. Most fire extinguishers on the market currently use mechanical pressure gauges or simple LED pressure measurement alarm systems. Mechanical pressure gauges are dial pointer type, and the mechanical pressure indication number needs to be read manually, so personal subjective recognition errors often occur, resulting in inaccurate results. When affected by ambient temperature, the reading results also have certain deviations; the LED pressure measurement alarm system is only suitable for regional alarms where the fire extinguisher is placed, and cannot achieve remote alarm monitoring.

[0003] Moreover, the management of fire extinguishers is currently managed by the user units themselves. The security personnel of the user units are limited in their knowledge of fire extinguishers and their lack of attention to safety responsibilities, and often manage them improperly. As a result, when a fire breaks out in the user unit, many fire extinguishers fail and cannot be used, and the fire cannot be controlled in time. Therefore, there is a need for a system that can remotely monitor and manage fire extinguishers, and perform real-time monitoring and management of fire extinguishers on behalf of the user unit. Summary of the invention

[0004] The technical problems to be solved by the present invention are:

[0005] In order to solve the problem that existing fire extinguishers are not adequately monitored when placed, which may result in insufficient pressure or failure and thus making them unusable in case of fire.

[0006] The present invention adopts the following technical solutions to solve the above technical problems:

[0007] The present invention provides an intelligent monitoring device for a fire extinguisher, comprising a connecting pipe arranged on a fire extinguisher, wherein one end of the connecting pipe is connected to a fire extinguisher bottle body of the fire extinguisher, and the other end of the connecting pipe is connected to a monitoring device, wherein the monitoring device comprises a monitoring box, a pressure sensor, a processor, a positioning module, a communication module, a display module, an alarm module and a power module, wherein the processor, the positioning module, the communication module, the display module, the alarm module and the power module are all arranged in the monitoring box, wherein the pressure sensor is arranged in the connecting pipe and connected to the processor, wherein the processor is connected to the display module, the positioning module and the alarm module, wherein the processor is connected to a remote terminal via a communication module, and wherein the power module is used to supply power to the pressure sensor, the processor, the positioning module, the communication module, the display module and the alarm module.

[0008] Furthermore, the power module has an internal automatic switch and an external manual switch.

[0009] Furthermore, the processor is used to compare the pressure data with the pressure threshold, and presets the pressure alarm lower limit as F1, the pressure threshold upper limit as F2, and the pressure threshold lower limit as F3 in advance. When the pressure data is greater than F1, the pressure situation is judged as a pressure alarm; when the pressure data is greater than F2 and less than F1, the pressure situation is judged as excessive pressure; when the pressure data is greater than F3 and less than F2, the pressure situation is judged as normal pressure; when the pressure data is less than F3, the pressure situation is judged as too low pressure; the processor transmits the pressure data, the pressure situation, and the battery level data of the power module to the display module through the communication module.

[0010] Furthermore, the display module is a display screen including an electronic pressure gauge.

[0011] Furthermore, the alarm module includes a speaker and a warning light, and the speaker and the warning light are installed on the monitoring box.

[0012] Furthermore, a first limiting sleeve is provided on the side of the connecting pipe close to the monitoring box, the first limiting sleeve is fixedly sleeved with the outer wall of the connecting pipe, a second limiting sleeve is provided on the side of the connecting pipe close to the fire extinguisher bottle body, the outer wall of the second limiting sleeve is provided with an external thread, and the connecting pipe is connected to the fire extinguisher bottle body through threads.

[0013] Furthermore, the processor compares the location information transmitted by the positioning module with the initial location information of the fire extinguisher by presetting the location threshold in advance. When the difference between the updated location data of the fire extinguisher and the original location data exceeds the location threshold, it is transmitted to the fire extinguisher monitoring center through the communication module.

[0014] A monitoring method of a fire extinguisher intelligent monitoring device comprises the following steps:

[0015] S1. Install the monitoring device on the fire extinguisher bottle through the connecting pipe;

[0016] S2. Enter the identification information corresponding to the fire extinguisher into the fire extinguisher monitoring system, wherein the identification information includes the production date, shelf life and serial number;

[0017] S3, turn on the manual switch of the power module in the monitoring device;

[0018] S4, transmitting the pressure data in the fire extinguisher bottle obtained by the pressure sensor to the processor;

[0019] S5. The processor compares the pressure data transmitted by the pressure sensor with a preset pressure threshold, thereby determining the pressure condition in the fire extinguisher bottle;

[0020] S6, displaying the pressure data obtained by the pressure sensor, the pressure condition obtained by comparing the pressure data with the pressure threshold, and the power information of the power module through the electronic pressure gauge of the display module;

[0021] S7, transmitting the information of the display module and the fire extinguisher location information obtained by the positioning module to the fire extinguisher monitoring center through the communication module, and the fire extinguisher monitoring center matches this information with the fire extinguisher identification information entered in step S2;

[0022] S8. Turn off the manual switch of the power module in the monitoring device to complete a data update.

[0023] Further, in step S3, the fire extinguisher intelligent monitoring device turns on the monitoring device through the automatic switch of the power module.

[0024] Further, in step S5, when the pressure condition determined by the processor is too high or too low, the warning light of the alarm module lights up; when the pressure condition determined by the processor is a pressure alarm, the speaker and warning light of the alarm module are controlled to sound an alarm; at the same time, the information of the abnormal pressure condition is transmitted to the fire extinguisher monitoring center through the communication module.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The pressure sensor monitors the pressure in the fire extinguisher bottle and transmits the pressure data to the processor. The processor transmits the pressure data, the pressure conditions determined by the threshold and the power of the power module to the display module, and transmits these data and the location of the fire extinguisher to the fire extinguisher monitoring center through the communication module. The pressure data is displayed through the display module for personnel to view on site. The information transmitted to the fire extinguisher monitoring center facilitates the staff to remotely understand the use of the fire extinguisher, thereby achieving the purpose of remote monitoring of the fire extinguisher.

[0027] 2. If the pressure data is not within the normal pressure range, the fire extinguisher pressure data and pressure conditions as well as the location information of the fire extinguisher will be transmitted to the fire extinguisher monitoring center through the communication module, so that the fire extinguisher monitoring center can arrange professionals to conduct on-site inspections according to the location information. If the pressure data reaches the lower limit of the pressure alarm, the fire extinguisher has the risk of explosion, and the alarm module will issue a warning so that surrounding personnel can discover it in time and evacuate to a safe area.

[0028] 3. If the difference between the fire extinguisher location information obtained by the positioning module and the initial location information of the fire extinguisher is greater than the preset location threshold, it generally means that a fire has occurred. At this time, it is transmitted to the fire extinguisher monitoring center through the communication module so that professional technicians can reach the place where the fire occurred. It is also convenient to check the specific location of the fire extinguisher on site and facilitate the subsequent maintenance of the fire extinguisher.

[0029] 4. The electronic pressure gauge of the display module replaces the original mechanical pressure gauge of the fire extinguisher, which makes the display more convenient and intuitive. BRIEF DESCRIPTION OF THE DRAWINGS
