Description

Technical Field

[0001] The utility model relates to the technical field of intelligent instruments, in particular to a gas alarm linkage system. Background Art

[0002] A gas meter is an instrument used to measure the amount of gas consumed in a home or commercial place. It is directly connected to the gas supply pipeline. The main function of a gas alarm is to sound an alarm when a gas leak occurs. It prevents possible fire or explosion accidents by detecting the gas concentration.

[0003] At present, most gas alarms used to detect methane concentrations in the environment are directly connected to gas meters by wire or Bluetooth. Specifically, wired connection usually refers to connecting the gas alarm and the gas meter through wires. This method requires pre-laying wires between the alarm and the gas meter, which is cumbersome to install and not suitable for long-distance installation. Although Bluetooth connection does not require laying wires, Bluetooth communication technology itself has certain transmission distance limitations, and its signal will be attenuated by obstacles (such as walls). Therefore, the existing connection method between gas alarms and gas meters limits the installation of gas alarms to be close to the gas meter, and there are technical problems such as large interaction distance restrictions and inability to receive alarm information in time. Especially for outdoor meter users, due to the limited installation location of the gas alarm, it is extremely inconvenient for users to grasp the current status of the gas meter in real time, and it is difficult for managers to control the operation of the gas meter in time.

Therefore, it should not be understood as a limitation on the present invention.

[0026] Please refer to the attached Figure 1 , Figure 1 A schematic diagram of the structure of a gas alarm linkage system provided in an embodiment of this specification is shown.

[0027] like Figure 1 As shown, the gas alarm linkage system may include at least: a 5G Bluetooth gateway, a cloud platform, a gas alarm, a gas meter and a power management module. The 5G Bluetooth gateway is provided with a first network interface 1, a second network interface 2 and a third network interface 3. The first network interface 1 is communicated with the cloud platform, the cloud platform is used for data storage and control instruction issuance, the second network interface 2 is communicated with the gas alarm, the third network interface 3 is communicated with the gas meter, the 5G Bluetooth gateway is used to receive signals from the gas alarm, exchange data with the cloud platform and control the gas meter, and the power management module is used to power the 5G Bluetooth gateway.

[0028] On the other hand, in this embodiment, the 5G Bluetooth gateway is provided with an extended network interface, which is connected to other home appliances for communication and linkage control.

[0029] This embodiment designs a 5G Bluetooth gateway as a central hub, which does not require pre-laying of wires between the gas alarm and the gas meter, reducing the difficulty and cost of installation, and realizing a wider range of gas leakage control of the gas alarm, overcoming the technical problems of Bluetooth communication distance limitation and signal attenuation. It is not only suitable for outdoor meter users, but also can be applied to the connection between indoor gas alarms and gas meters, and has broad application prospects. At the same time, combined with the connection between the cloud platform and the 5G Bluetooth gateway as the central hub, users and managers can grasp the working status of the gas meter and the alarm information issued by the gas alarm in real time, realize remote control of the gas meter, and improve the safety and convenience of gas use to a certain extent. Through the design of the extended network interface, the 5G Bluetooth gateway can communicate and connect with other home appliances to realize the linkage control of a common set of gateways, thereby realizing the scenario-based application of smart homes and improving the compatibility and flexibility of the system. This embodiment uses an independent power management module to power the 5G Bluetooth gateway, which can ensure the stability of power supply.

[0030] Please see attached Figure 2 , Figure 2 A schematic diagram of the structure of a gas alarm linkage system provided in an embodiment of this specification is shown.

[0031] like Figure 2 As shown, the 5G Bluetooth gateway includes a 5G unit 4, a Bluetooth unit 5, a controller 6, a storage unit 7 and an alarm module. The 5G unit 4, the Bluetooth unit 5 and the storage unit 7 are all connected to the controller 6, the output end of the controller 6 is connected to the alarm module, one end of the first network interface 1 is connected to the cloud platform, the other end of the first network interface 1 is connected to the 5G unit 4, one end of the second network interface 2 is connected to the gas alarm, the other end of the second network interface 2 is connected to the Bluetooth unit 5, one end of the third network interface 3 is connected to the gas meter, and the other end of the third network interface 3 is connected to the Bluetooth unit 5.

[0032] In this embodiment, a master-slave integrated 5G Bluetooth gateway design is adopted to connect the gas alarm and the gas meter to the 5G Bluetooth gateway via Bluetooth, and the 5G Bluetooth gateway unit is used as a hub to realize real-time communication between the gas alarm and the gas meter. At the same time, through the expansion of the 5G Bluetooth gateway, a wider range of gas leak control of the gas alarm is realized, and the coverage area of ​​safety monitoring is improved. Moreover, the combination of 5G unit 4 and Bluetooth unit 5 can better resist interference and provide a more stable and high-speed data transmission channel, which is crucial for real-time monitoring and rapid response to emergencies. By interacting with the cloud platform through the 5G unit 4, users and managers can obtain various meter information and control the gas meter in real time through the cloud platform, thereby realizing timely information acquisition and linkage control of the gas network of the entire community.

[0033] On the other hand, in this embodiment, the power management module includes an electromagnetic compatibility protection circuit and an AC / DC unit. The input end of the electromagnetic compatibility protection circuit is connected to the mains, the output end of the electromagnetic compatibility protection circuit is connected to the input end of the AC / DC unit, and the output end of the AC / DC unit is electrically connected to the 5G Bluetooth gateway.

[0034] It is understandable that in this embodiment, the mains power supply first passes through the electromagnetic compatibility (EMC) protection circuit to ensure that the electromagnetic interference (EMI) during the power supply process is controlled within a reasonable range to prevent interference with other electronic equipment or communication lines, and also helps to improve the reliability and stability of the system. Among them, the electromagnetic compatibility protection circuit may include components such as filters, isolation transformers, rectifiers, capacitors, etc., which work together to reduce noise and spikes to ensure the stability and purity of the power supply. Subsequently, the power supply processed by the electromagnetic compatibility protection circuit is connected to the AC / DC module, and the alternating current (AC) is converted into direct current (DC) through the AC / DC module to provide the required DC power supply voltage for each electronic component in the 5G Bluetooth gateway.

[0035] Therefore, through the power management module, it can be ensured that the 5G Bluetooth gateway can obtain stable, pure and electromagnetic compatibility-compliant power supply to ensure the normal operation and performance of the gas alarm linkage system.

[0036] On the other hand, in the present embodiment, the 5G Bluetooth gateway is provided with a reset circuit 8, which is connected to the controller 6. The reset circuit 8 is used to directly reset the controller 6 of the 5G Bluetooth gateway when the 5G Bluetooth gateway is in an abnormal working state without disconnecting the mains power.

[0037] For example, the reset circuit 8 in this embodiment may include a power input terminal, a fuse / circuit breaker, and a reset controller, wherein the power input terminal is directly connected to the mains; the fuse or circuit breaker is installed between the power input terminal and the reset controller to provide overload protection; the reset controller is an electronic switch, which can be remotely triggered, for example, through a network or a physical button. This reset controller will be connected to the power input terminal and control the output of the reset signal, and the reset signal output is connected to the controller 6 of the 5G Bluetooth gateway. An indicator light can also be added to connect to the output terminal of the reset controller to display the working status of the device, such as normal operation, resetting, etc. The specific implementation of the reset circuit 8 is as follows: when the 5G Bluetooth gateway needs to be reset, the reset controller can be remotely triggered to generate a pulse signal from the reset signal output, and this pulse signal will be transmitted to the controller 6 of the 5G Bluetooth gateway to reset it. Since the entire process is carried out when the power is on, there is no need to disconnect the mains.

[0038] Through the design of the reset circuit 8, this embodiment can remotely restore the controller 6 of the 5G Bluetooth gateway to a normal working state in a timely manner when the system is in an abnormal working state, so that the gas meter and the gas alarm can be better integrated into the gas alarm linkage system, and centralized monitoring of the cloud platform is realized, which not only improves the efficiency of fault handling, but also avoids users or managers from directly contacting the equipment casing that may be energized, thereby reducing safety risks.

[0039] On the other hand, in this embodiment, the alarm module includes a display unit, which is connected to the output end of the controller 6, and the display unit is used to display the working status of the 5G Bluetooth gateway, the meter gas usage information and the alarm information.

[0040] On the other hand, in this embodiment, the 5G Bluetooth gateway is provided with a touch control unit 9, which is connected to the input end of the controller 6, and the touch control unit 9 is used for touch screen switching.

[0041] On the other hand, in this embodiment, the alarm module includes a buzzer circuit, which is connected to the output end of the controller 6. The buzzer circuit is used to be triggered when the controller 6 outputs an alarm message and when the controller detects a touch unit signal.

[0042] It can be understood that the buzzer circuit in this embodiment is triggered in at least the following two situations:

[0043] 1. The gas alarm transmits the monitoring data to the controller of the 5G Bluetooth gateway. When the controller outputs the alarm information after analysis, the buzzer circuit is triggered to alert the user or manager;

[0044] 2. When the controller detects a touch signal of the touch unit, the buzzer circuit is triggered to prompt the user that the touch signal has been detected.

[0045] On the other hand, in this embodiment, the gas alarm linkage system includes a shell and a cover, the shell is placed inside the wall, the cover and the 5G Bluetooth gateway are installed on the wall surface, the shell is connected to the cover, and the power management module is installed inside the shell. That is, the electromagnetic compatibility protection circuit and the AC / DC unit are inside the shell and placed inside the wall; the rest of the parts are installed on the wall surface together with the cover, the overall structure is small, and the installation is convenient. The size of the exposed part of the wall is only 100mm*100mm*10mm.

[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
