Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of security, and in particular relates to an intelligent fire extinguisher monitoring system and a monitoring method. Background Art
[0002] For businesses or departments with high fire safety requirements, such as gas stations and oil tank farms, in addition to using fire hydrants to provide fire extinguishing agents, they also have a large number of portable fire extinguishers on hand. However, to ensure these portable fire extinguishers are always effective, they need to be regularly inspected and tested for pressure, fire extinguishing agent effectiveness, and other factors. These inspections require specialized equipment and require the fire extinguishers to be moved from their original designated locations to the inspection location. This results in high labor costs and creates a period of unavailability of fire extinguishers, posing a safety hazard. Summary of the Invention
[0003] The purpose of the present invention is to provide an intelligent fire extinguisher monitoring system and monitoring method, which uses intelligent technology to replace manual inspections, reduce labor costs, and improve the efficiency of fire extinguisher inspections and full life cycle monitoring.
[0004] To achieve the above objectives, this application is implemented through the following technical solutions:
[0005] An intelligent fire extinguisher monitoring system includes a fire extinguisher bracket arranged at a set position, a fire extinguisher arranged on the fire extinguisher bracket, a status nameplate arranged on the fire extinguisher, and a status detection component arranged on the fire extinguisher bracket. The status detection component is electrically connected to the input end of a data processing module, and an early warning output module is electrically connected to the output end of the data processing module.
[0006] Furthermore, the status plate includes at least the fire extinguisher number, the type of fire extinguishing agent and the expiration date.
[0007] Furthermore, the status detection component includes a pressure sensor, a temperature sensor, a gas leakage sensor and a weight sensor. The pressure sensor is used to detect the pressure gauge data of the fire extinguisher, the temperature sensor is used to detect the temperature data of the current fire extinguisher, the weight sensor is used to detect the weight data of the fire extinguisher, and the gas leakage sensor is used to detect the gas leakage data of the current fire extinguisher.
[0008] Furthermore, the weight sensor is arranged below the fire extinguisher bracket, and the fire extinguisher is arranged on the weight sensor.
[0009] Furthermore, the early warning output module includes at least a light alarm module and a sound alarm module.
[0010] An intelligent fire extinguisher monitoring method, using any of the above intelligent fire extinguisher monitoring systems, adopts the following steps:
[0011] S1. At set intervals, the pressure sensor, weight sensor, and temperature sensor transmit the pressure, weight, and temperature signals of the corresponding fire extinguisher to the controller. The controller matches the above signals with the stored nameplate information of the fire extinguisher and determines whether the corresponding fire extinguisher is a dry powder fire extinguisher or a carbon dioxide fire extinguisher. If it is a dry powder fire extinguisher, the process proceeds to step S2; if it is a carbon dioxide fire extinguisher, the process proceeds to step S3.
[0012] S2. If the weight of the fire extinguisher is within the set range, the controller does not send an alarm signal to the early warning output module. If the weight is not within the set range, the controller sends an alarm signal to the early warning module.
[0013] S3. If the pressure signal of the fire extinguisher is within the set range, proceed to step S4. If the pressure signal of the fire extinguisher is not within the set range, proceed to step S6.
[0014] S4. If the weight signal is within the set range, the controller does not send an alarm signal to the warning output module. If the weight signal is lower than the minimum value of the set range, the process proceeds to step S5.
[0015] S5. The controller determines whether it has received a gas leakage signal. If so, the controller sends a fire extinguishing agent leakage alarm signal. If not, the controller sends an alarm signal to the early warning module.
[0016] S6. If the pressure signal of the fire extinguisher is greater than the maximum value of the set range, the controller detects the temperature signal of the fire extinguisher. If the temperature signal is greater than the set value, the controller sends a high temperature alarm signal; if not, the controller sends a high pressure alarm;
[0017] If the pressure signal of the fire extinguisher is lower than the minimum value of the set range, the controller determines whether the weight signal is within the set range. If the weight signal is within the set range, the controller sends a pressure gauge damage alarm signal; if the weight signal is lower than the minimum value of the set range, the controller sends a fire extinguishing agent insufficient alarm signal.
[0018] Furthermore, if the weight signal transmitted by the weight sensor to the controller is zero, the controller detects whether a fire alarm occurs in the vicinity of the fire extinguisher. If so, it is determined that the fire extinguisher has been used. If not, an alarm is generated indicating that the fire extinguisher has been moved.
[0019] Furthermore, the nameplate information of the fire extinguisher stored in the controller includes the validity period data of the fire extinguishing agent. When the fire extinguishing agent is approaching the validity period, the controller sends a fire extinguishing agent expiration warning signal.
[0020] The beneficial effects of the present invention are:
[0021] The present invention integrates the nameplate information, status detection components and controller of the fire extinguisher through the intelligent fire extinguisher monitoring system, and replaces the current conventional manual inspection with intelligent technology, which can effectively reduce labor costs, and provide timely feedback on the status of the fire extinguisher, thereby improving the efficiency of fire extinguisher inspection and full life cycle monitoring. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 2 Schematic diagram of the intelligent fire extinguisher monitoring method of the present invention. DETAILED DESCRIPTION
[0024] The technical solution of the present invention is described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and cannot be interpreted as limiting the technical solution of the present invention.
[0025] like Figure 1 As shown, the present application provides an intelligent fire extinguisher monitoring system, including a fire extinguisher bracket set at a set position. The present application does not have specific requirements for the structure of the fire extinguisher bracket, and it can be changed according to the specific placement location, etc., as long as it can accommodate a fire extinguisher. In addition, there is no limit on the number of fire extinguisher brackets in this monitoring system, and it can be designed according to the needs of the enterprise. However, each fire extinguisher bracket is used to place a fire extinguisher. Multiple fire extinguisher brackets can be connected together or set separately without affecting the technical solution of the present application.
[0026] A status nameplate is provided on each fire extinguisher. The status nameplate of this application can number the fire extinguisher, the type of fire extinguishing agent, the filling date, the expiration date and other information, and the information on the status nameplate is saved in the controller.
[0027] A status detection component is provided on the fire extinguisher bracket. The status detection component is electrically connected to the input terminal of the data processing module, and the warning output module is electrically connected to the output terminal of the data processing module. In the present application, the status detection component includes a pressure sensor, a temperature sensor, a gas leakage sensor, and a weight sensor. The pressure sensor is used to detect the pressure gauge data of the fire extinguisher, the temperature sensor is used to detect the current temperature data of the fire extinguisher, the weight sensor is used to detect the weight data of the fire extinguisher, and the gas leakage sensor is used to detect the gas leakage data of the current fire extinguisher.
[0028] In the present application, the weight sensor is arranged below the fire extinguisher bracket, and the fire extinguisher is arranged on the weight sensor to ensure that the weight sensor can detect the weight of the fire extinguisher.
[0029] The warning output module of the present application includes at least a light alarm module and a sound alarm module.
[0030] like Figure 2 As shown, the present application also provides an intelligent fire extinguisher monitoring method, using any of the above intelligent fire extinguisher monitoring systems, and adopting the following steps:
[0031] S1. Set the time for each interval. In this application, the interval does not need to be too short. Usually, 0.5 hours, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 3.5 hours, and 4 hours are selected. Of course, those skilled in the art can also select other time intervals as needed, which does not affect the implementation of the technical solution of this application. In order to save energy, each part can enter a dormant state during the interval. The pressure sensor, weight sensor, and temperature sensor transmit the pressure signal, weight signal, and temperature signal of the corresponding fire extinguisher to the controller. The controller matches the above signals with the stored nameplate information of the fire extinguisher and determines whether the corresponding fire extinguisher is a dry powder fire extinguisher or a carbon dioxide fire extinguisher. If it is a dry powder fire extinguisher, it goes to step S2, and if it is a carbon dioxide fire extinguisher, it goes to step S3. Because among the types of fire extinguishers used by enterprises, carbon dioxide fire extinguishers or carbon dioxide fire extinguishers are basically used, due to the properties of the two fire extinguishing agents, they need to be processed separately during the monitoring process.
[0032] S2. If the weight of the fire extinguisher is within the set range, the controller does not send an alarm signal to the early warning output module. If the weight is not within the set range, the controller sends an alarm signal to the early warning module. This step is for the stability of the fire extinguishing agent in the dry powder fire extinguisher. By detecting the weight of the dry powder fire extinguisher, a routine inspection of the dry powder fire extinguisher can be achieved.
[0033] The present application also includes that if the weight signal transmitted by the weight sensor to the controller is zero, the controller detects whether there is a fire alarm in the vicinity of the fire extinguisher. If so, it is determined that the fire extinguisher has been used. If not, a fire extinguisher displacement alarm is invented. When a fire alarm occurs in the fire extinguisher accessory, the fire extinguisher is usually used. When the fire extinguisher is removed from the fire extinguisher bracket, the data detected by the weight sensor is naturally zero. However, at the same time, it is inevitable that there will be false alarms due to, for example, a weight sensor failure. In order to avoid this problem, the controller can simultaneously detect the pressure sensor signal. If the pressure sensor signal is normal, it indicates that the fire extinguisher is still on the fire extinguisher bracket and has not been moved. At this time, it can be determined that the weight sensor has failed. The controller can send a corresponding alarm signal to remind relevant personnel to repair or replace the weight sensor. If the pressure sensor signal is also no, it is determined that the fire extinguisher has been moved. At this time, regardless of whether a fire alarm occurs, relevant personnel need to be notified to check and confirm.
[0034] S3. If the pressure signal of the fire extinguisher is within the set range, proceed to step S4. If the pressure signal of the fire extinguisher is not within the set range, proceed to step S6. Each fire extinguisher is equipped with a pressure gauge for detecting the pressure of the fire extinguishing agent in the fire extinguisher. Whether the pressure gauge is within the set range is also a step for checking the fire extinguisher.
[0035] S4. If the weight signal is within the set range, the controller does not send an alarm signal to the early warning output module. If the weight signal is lower than the minimum value of the set range, it enters step S5. This step is for the detection of carbon dioxide fire extinguishers. First, it is determined whether the amount of carbon dioxide in the carbon dioxide fire extinguisher is within the set range.
[0036] S5. The controller determines whether it has received a gas leakage signal. If so, the controller sends a fire extinguishing agent leakage alarm signal. If not, the controller sends an alarm signal to the early warning module. Because if the fire extinguishing agent is leaking, it can naturally be detected by the weight sensor.
[0037] S6. If the pressure signal of the fire extinguisher is greater than the maximum value of the set range, the controller detects the temperature signal of the fire extinguisher. If the temperature signal is greater than the set value, the controller sends a high temperature alarm signal; if not, the controller sends a high pressure alarm;
[0038] If the pressure signal of the fire extinguisher is lower than the minimum value of the set range, the controller determines whether the weight signal is within the set range. If the weight signal is within the set range, the controller sends a pressure gauge damage alarm signal; if the weight signal is lower than the minimum value of the set range, the controller sends a fire extinguishing agent insufficient alarm signal.
[0039] In the present application, the nameplate information of the fire extinguisher stored in the controller includes the validity period data of the fire extinguishing agent. When the fire extinguishing agent is approaching the validity period, the controller sends a fire extinguishing agent expiration warning signal.
[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other manner. Any person skilled in the art may utilize the above-disclosed technical content to modify or modify the present invention into equivalent embodiments. However, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical content of the present invention and are based on the technical essence of the present invention remain within the scope of protection of the present invention.
