Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fire extinguishers, and particularly relates to a mobile fire extinguisher weighing alarm device. BACKGROUND

[0002] As a key fire-fighting equipment for initial fire extinguishing, the effectiveness of the fire extinguishing agent in the fire extinguisher directly depends on the accuracy of the filling amount, and whether it can work normally directly relates to the success rate of initial fire extinguishing. According to relevant standards such as the "Building Fire Extinguisher Configuration Acceptance and Inspection Specification" (GB 50444-2023), the fire extinguisher needs to be regularly weighed, and if the quality loss caused by the leakage of the fire extinguishing agent exceeds 5%, it must be supplemented in time to ensure that it can play an effective role when a fire occurs.

[0003] The existing fire extinguisher weighing management mainly relies on the following technical solutions, and each solution has obvious defects:

[0004] Traditional pressure gauge detection method: this method judges whether the fire extinguisher is normal by observing the pressure indication of the pressure gauge. The defects of this method are: there is a serious applicability defect, which cannot be applied to dry powder and carbon dioxide fire extinguishers, because the pressure indication cannot show the amount of the agent. Actual case data shows that 32% of the fire extinguishers have insufficient internal agents although the pressure is normal, which directly leads to an increased risk of fire extinguisher failure in emergency situations.

[0005] Fixed weighing platform detection method: this method sets a fixed electronic scale in a fire station or warehouse and the like, and detects the fire extinguisher by manually disassembling and carrying it from the placement point to the weighing platform for static weighing, and displays the quality data through the instrument. The defects of this method are: the operation process is complicated, and the carrying process is easy to cause damage to the fire extinguisher; real-time monitoring cannot be realized during detection, the detection period is long, and the fire extinguisher has a safety hidden danger window period; and this method lacks data traceability function, and manual recording of data is prone to errors. At the same time, the average time for detecting a single fire extinguisher is 15 minutes, which greatly affects the efficiency of large-scale inspection.

[0006] Simple hook type weighing device detection method: this method uses a portable spring scale or an electronic lifting scale to hang the fire extinguisher for weighing, and some models have an out-of-limit buzzer prompting function. The defects of this method are: manual operation is required, and automatic rotation of multiple fire extinguishers cannot be realized; it does not have a position recognition function, and it is difficult to correspond to a specific fire extinguisher number, resulting in low management efficiency. In addition, the error of such mobile detection equipment on the market exceeds 5% (actual measurement data) in a vibrating environment, and the detection accuracy required by the fire regulations is usually ≤3%, so such equipment cannot meet the hard requirement of accuracy.

[0007] In summary, existing detection technologies have numerous problems, exhibiting significant limitations in accuracy, efficiency, and applicability, and thus failing to adequately meet practical detection needs. The industry urgently requires a high-precision, portable detection solution that supports real-time alarms to address the inability to simultaneously provide on-site detection, continuous detection, data recording, automated detection, and location identification during fire extinguisher weighing. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the present invention aims to provide a mobile fire extinguisher weighing alarm device and method that integrates mobile detection, intelligent diagnosis, and remote monitoring. This solves the problems of low fire extinguisher detection efficiency, isolated data, and delayed response in existing technologies, improves fire extinguisher maintenance efficiency, and ensures that the fire extinguisher is always in an effective standby state.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0010] A mobile fire extinguisher weighing alarm device includes a mobile support platform, a weighing module, a positioning and identification module, a control center, and a communication alarm module. The mobile support platform serves as the carrier for the other modules. The positioning and identification module records the physical location of the fire extinguisher in real time and automatically identifies the fire extinguisher information. The weighing module accurately measures the current weight of the fire extinguisher and uploads the weighing data to the control center. The control center analyzes weight changes. If a leakage exceeding a threshold is detected, the communication alarm module is triggered to issue an alarm, thereby achieving fully automated closed-loop management from detection to alarm.

[0011] Furthermore, in the mobile fire extinguisher weighing alarm device described above, the mobile support platform includes a chassis, a drive wheel set, and an electric drive system.

[0013] Furthermore, in the mobile fire extinguisher weighing alarm device described above, the positioning and identification module also includes a QR code scanner, which is used to identify the paper label of a traditional fire extinguisher.

[0014] Furthermore, in the mobile fire extinguisher weighing alarm device described above, the weighing module includes a pressure sensor, a status detection sensor, a micro data processor, mechanical grippers, and a weighing tray.

[0015] Furthermore, in the mobile fire extinguisher weighing alarm device described above, the control center is used for data analysis, coordinated control, data processing and early warning, and cloud data uploading. The software part of the control center mainly includes a main control chip, a main control program, a detection alarm program, a quality analysis program, a task scheduling system, a communication protocol stack, and a data storage unit. The task scheduling system is used to manage automatic inspection routes and detection sequences; the communication protocol stack can provide wireless and Bluetooth multi-channel transmission.

[0016] Furthermore, in the mobile fire extinguisher weighing alarm device described above, the communication alarm module is used for real-time alarm, data upload, and remote interaction. The communication alarm module includes a communication / wireless module and an audible and visual alarm.

[0017] The method for triggering a fire extinguisher weighing alarm based on the portable fire extinguisher weighing alarm device described above includes the following steps:

[0018] S1. The mobile carrier platform navigates to the target fire extinguisher location via positioning.

[0019] S2. Identify the fire extinguisher's identity information and record its current spatial coordinates through the positioning and identification module, and transmit the fire extinguisher's location data and identity information to the control center.

[0020] S3. High-precision weighing is performed through the weighing module and the data is transmitted to the control center;

[0021] S4. The control center analyzes the current weight change of the fire extinguisher, generates an early warning command based on the analysis results, and transmits the early warning command to the communication alarm module.

[0022] S5. After receiving the instruction signal from the control center, the communication alarm module performs both local and cloud-based alarms.

[0023] Furthermore, in the fire extinguisher weighing alarm method described above, step S2 specifically involves: automatically scanning the fire extinguisher's electronic tag using an RFID reader in the positioning and identification module to obtain the fire extinguisher's unique ID and basic information; when the fire extinguisher's tag is a paper tag, using a QR code scanner to identify the fire extinguisher's unique ID and basic information; recording the fire extinguisher's current spatial coordinates through a positioning base station, and binding and packaging the fire extinguisher's location data with its identity information for transmission to the control center.

[0024] Furthermore, in the fire extinguisher weighing alarm method described above, step S3 specifically includes:

[0025] S31. The mechanical gripper picks up the fire extinguisher to be tested and retrieves it into the weighing tray;

[0026] S32. The status detection sensor detects whether the fire extinguisher is in place. Once in place, the pressure sensor measures the weight of the fire extinguisher and the micro data processor calculates the net weight of the fire extinguisher.

[0027] S33. Upload the net weight data of the fire extinguisher to the control center and start the quality analysis program;

[0028] S34. After weighing, the mechanical gripper removes the fire extinguisher according to the instructions from the control center, completing one weighing cycle.

[0029] Furthermore, in the fire extinguisher weighing alarm method described above, step S4 specifically includes:

[0030] S41. The main control program receives data from each sub-item in real time through the communication interface.

[0031] S42. The communication protocol stack parses the received raw information and converts it into binary format;

[0032] S43. The task scheduling program performs subsequent quality analysis, detection alarms, and data storage through a preset weighing program;

[0033] S44. The quality analysis program receives and analyzes the net weight data of the fire extinguisher transmitted from the weighing module.

[0034] S45. The main control program makes logical judgments based on the weight and positioning information of the fire extinguisher being tested. If the fire extinguisher is normal, it sends a command to the mechanical gripper to pick up the fire extinguisher; if the fire extinguisher is abnormal, it activates the detection alarm program.

[0035] S46. The detection alarm program receives data from the quality analysis program. Once an anomaly is detected, it immediately generates alarm information and triggers a local alarm, and uploads the alarm data to the data storage unit for storage.

[0036] Furthermore, in the fire extinguisher weighing alarm method described above, the local alarm in step S5 specifically involves triggering a local audible and visual alarm device via a communication protocol stack. The audible and visual alarm device triggers the alarm via a buzzer and an LED.

[0037] Specifically, the cloud alarm is uploaded to the cloud platform via a communication protocol in the form of wireless or Bluetooth, and the cloud platform sends warning notifications to multiple platforms.

[0038] Compared with the prior art, the portable fire extinguisher weighing alarm device and method provided by the present invention have the following beneficial effects:

[0039] This invention achieves a revolutionary breakthrough in the full lifecycle management of fire extinguishers by integrating an autonomous navigation mobile platform, a high-precision dynamic weighing module, and a positioning and identification module. The device, through its positioning and identification module, can accurately locate and automatically identify fire extinguishers. It can autonomously inspect fire extinguishers within a preset area and identify and alarm on expired fire extinguishers, realizing an intelligent transformation from periodic spot checks to real-time monitoring. This completely solves the industry pain points of traditional fire extinguisher management, such as unclear location, high missed detection rate, and delayed response. Attached Figure Description

Finally, the modules are integrated into a mobile cloud platform to realize remote online command and control, and finally extended to the fire protection Internet of Things platform to realize intelligent linkage, thus building a comprehensive upgrade from single-machine detection to system management.

[0080] The present invention also provides a method for using the above-described device to generate a fire extinguisher weighing alarm. Figure 3 The flowchart of the method is shown, which specifically includes the following steps:

[0081] S1. The mobile carrier platform navigates to the location of the target fire extinguisher using positioning.

[0082] Specifically, the mobile carrier platform receives inspection instructions from the control center, obtains its precise location coordinates through the positioning base station, and drives the omnidirectional wheel assembly to the target fire extinguisher location and docks in accordance with the preset navigation route.

[0083] S2. The positioning and identification module identifies the fire extinguisher's identity information and records its current spatial coordinates. The fire extinguisher's location data and identity information are then bound, packaged, and transmitted to the control center.

[0084] Specifically, the RFID reader in the positioning and identification module automatically scans the electronic tag of the fire extinguisher to obtain the fire extinguisher's unique ID and basic information. When the fire extinguisher's tag is a traditional paper tag, a QR code scanner is used to identify the fire extinguisher's unique ID and basic information. The positioning base station records the fire extinguisher's current spatial coordinates and binds the fire extinguisher's location data with its identity information, then packages and transmits it to the control center.

[0085] S3, the weighing module performs high-precision weighing and transmits the data to the control center.

[0086] The weighing module's operating steps include: S31, the mechanical gripper picks up the fire extinguisher to be tested and retrieves it into the weighing tray; S32, the status detection sensor detects whether the fire extinguisher is in the correct position, and after it is in the correct position, the pressure sensor measures the weight of the fire extinguisher, and the micro data processor calculates the net weight of the fire extinguisher; S33, the net weight data of the fire extinguisher is uploaded to the control center, and the quality analysis program is started; S34, after the weighing is completed, the mechanical gripper picks up the fire extinguisher according to the command of the control center, completing one weighing cycle.

[0087] S4. The control center analyzes the current weight change of the fire extinguisher, generates an early warning command based on the analysis results, and transmits the early warning command to the communication alarm module.

[0088] The control center's operating steps include: S41, the main control program receives data from each sub-item in real time through the communication interface; S42, the communication protocol stack parses the received raw information and converts it into binary format, including weight information, positioning information, etc.; S43, the task scheduling program executes subsequent quality analysis, detection alarm, and data storage through a preset weighing program; S44, the quality analysis program receives and analyzes the net weight of the fire extinguisher transmitted from the weighing module; S45, the main control program makes logical judgments based on the weight, positioning information, and other information of the tested fire extinguisher. If the fire extinguisher is normal, it sends a command to the mechanical gripper to remove the fire extinguisher; if the fire extinguisher is abnormal, it activates the detection alarm program; S46, the detection alarm program runs continuously, receiving data from the quality analysis program. Once an abnormality is detected, it immediately generates alarm information and triggers a local alarm, and uploads the alarm data to the data storage unit; S47, the data storage unit is responsible for storing weighing records, fire extinguisher positioning, quality analysis data, alarm event records, and other data.

[0089] S5, the communication alarm module will trigger both local and cloud-based alarms upon receiving the command signal from the control center.

[0090] The local alarm is specifically triggered by the communication protocol stack, which then uses an 85dB buzzer and a tri-color LED to sound an alarm.

[0091] Cloud-based alarms specifically involve uploading alert information to a cloud platform via wireless or Bluetooth using a communication protocol stack. The cloud platform can be a computer or a mobile phone. It first receives and stores the detection data uploaded by the terminal, provides a visual interactive interface, supports historical data tracing, and sends alert notifications to multiple platforms (PC / APP / SMS).

[0092] The weighing alarm method provided by this invention involves a mobile carrier platform navigating to the target fire extinguisher location. The RFID module in the positioning and identification module automatically identifies the fire extinguisher's identity information, and the weighing module performs high-precision weighing and transmits the data to the control center. The control center analyzes the weight changes and compares them with historical data. If a leakage exceeding the threshold is detected, a local audible and visual alarm is triggered through the communication protocol stack, and the location information, ID number, and abnormal data are simultaneously uploaded to the cloud platform for alarm activation, completing a fully automated closed-loop management from detection to alarm activation.

[0093] The mobile fire extinguisher weighing alarm device and method provided by this invention uses a high-precision weighing module mounted on a self-moving carrier platform and combines a dynamic filtering algorithm to achieve stable measurement in a vibration environment. It uses RFID and spatial positioning technology to automatically associate the fire extinguisher's identity and location information. When the detected mass loss exceeds the threshold or the predicted expiration date is approaching, it can accurately alarm through the cloud platform to identify the failed fire extinguisher.

[0094] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention is also intended to include these modifications and variations.
