Description

Technical Field

[0001] This utility model relates to the field of ultrasonic gas meter technology, specifically a wireless remote ultrasonic gas meter. Background Technology

[0002] Wireless remote ultrasonic gas meters are intelligent gas metering devices that integrate ultrasonic metering technology and wireless communication technology. They are mainly used to accurately measure gas flow and realize remote data transmission, promoting the upgrade of gas metering from the traditional mechanical mode to the intelligent Internet of Things mode.

[0003] In the field of gas metering, in-home meter reading, as a traditional data collection method, has long faced the dual dilemmas of efficiency and management. Traditional mechanical diaphragm gas meters rely on manual in-home meter reading, which is difficult and has a low success rate due to factors such as differences in users' work and rest schedules and increased awareness of privacy protection. Moreover, manual inspection methods cannot monitor the operating status of gas meters and users' gas usage in real time. Gas meter malfunctions and abnormal flow (such as leaks and gas theft) are difficult to detect in a timely manner, which may lead to safety accidents or economic losses.

[0004] To address these issues, we designed a wireless remote ultrasonic gas meter. Utility Model Content

[0005] The purpose of this invention is to provide a wireless remote ultrasonic gas meter to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a wireless remote ultrasonic gas meter, including an ultrasonic gas meter body and a main control box disposed on the ultrasonic gas meter body. The main control box is provided with a control board, and the control board is provided with a wireless communication module. The wireless communication module is an NB-10T communication module, and a central processor is installed on the control board. The central processor is connected to the NB-10T communication module by signal.

[0007] Furthermore, the control panel is also equipped with a valve control module, and the top wall of the ultrasonic gas meter body is connected to an air inlet and an air outlet. Both the air inlet and the air outlet are equipped with electrically controlled valves, and the electrically controlled valves are connected to the valve control module via signal.

[0008] Furthermore, an ultrasonic transducer is provided on the outer wall of the main control box, and an ultrasonic metering module is provided on the control board. The ultrasonic metering module is connected to the central processor via a signal connection.

[0012] Furthermore, a damping pad is connected to the bottom wall of the ultrasonic gas meter body, and a foot is connected to the other end of the damping pad.

[0013] Furthermore, the material of the foot pad is rubber.

[0014] The beneficial effects of this utility model are as follows: the ultrasonic metering module on the control board accurately calculates the gas flow rate based on parameters such as the time difference of ultrasonic waves propagating in the gas, and transmits the data to the central processor. Through the signal connection with the NB-10T communication module on the control board, the data is sent out wirelessly, realizing remote data transmission, which facilitates data collection and management by gas companies. By adopting NB-10T technology, the connection speed is fast, the signal penetration is good, the power consumption is low, the meter reading is accurate and fast, and the remote meter reading can be customized.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a wireless remote ultrasonic gas meter, including an ultrasonic gas meter body 1 and a main control box 7 installed on the ultrasonic gas meter body 1. An ultrasonic transducer is installed on the outer wall of the main control box 7, and an ultrasonic metering module is installed on the control board 11. The ultrasonic metering module is connected to the central processor via a signal connection. When gas flows inside the ultrasonic gas meter body 1, the ultrasonic transducer on the outer wall of the main control box 7 will emit and receive ultrasonic signals. The ultrasonic metering module on the control board 11 calculates the gas flow rate based on parameters such as the time difference of ultrasonic waves propagating in the gas and transmits the data to the central processor. The main control box 7 contains the control board 11, which is equipped with a wireless communication module. The wireless communication module is an NB-10T communication module, and the control board 11 is equipped with a central processor via a signal connection. The central processor is connected to the NB-10T communication module. The main control box 7 is equipped with an LCD display 5 and a counter 6. The central processor processes and analyzes the relevant data and then sends the gas usage information to the counter 6. The counter 6 records the cumulative gas usage and displays it intuitively to the user through the LCD display 5.

[0023] In practical implementation, regarding gas metering, when gas flows within the ultrasonic gas meter body 1, the ultrasonic transducer on the outer wall of the main control box 7 emits and receives ultrasonic signals. The ultrasonic metering module on the control board 11 accurately calculates the gas flow rate based on parameters such as the time difference of ultrasonic waves propagating in the gas and transmits the data to the central processor. The central processor processes and analyzes this data and then sends the gas usage information to the counter 6. The counter 6 records the cumulative gas usage and displays it intuitively to the user through the LCD screen 5. During data transmission, the central processor transmits the processed gas metering data and other relevant information wirelessly through a signal connection with the NB-10T communication module on the control board 11, enabling remote data transmission. This facilitates data collection and management for the gas company. The NB-10T technology offers fast connection speed, good signal penetration, low power consumption, accurate and rapid meter reading, and customizable remote meter reading capabilities. Furthermore, the NB-10T uses a dedicated communication frequency band, providing strong anti-interference capabilities, stable communication signals, and high carrying capacity, thus avoiding communication congestion.

[0024] See Figure 1 as well as Figure 4 As shown, a valve control module is also provided on the control panel 11. An air inlet 2 and an air outlet 3 are connected to the top wall of the ultrasonic gas meter body 1. The air inlet 2 and the air outlet 3 are welded onto the ultrasonic gas meter body 1. Both the air inlet 2 and the air outlet 3 are equipped with an electrically controlled valve 4. The electrically controlled valve 4 is an electromagnetically driven structure, which contains core components such as an electromagnetic coil, a valve core, and a spring. When the electromagnetic coil is energized, it generates an electromagnetic force that attracts the valve core, overcomes the spring force, and opens the valve, allowing gas to flow. When the electromagnetic coil is de-energized, the spring returns to its original position and pushes the valve core to close the valve and cut off the gas supply. The electrically controlled valve 4 is connected to the valve control module via a signal connection. The electrical signal output by the valve control module is transmitted to the control terminal of the electrically controlled valve 4 through a shielded cable, thereby effectively controlling the supply and cut-off of gas.

[0025] In practice, when the gas company needs to control the gas supply based on user payment status, safety monitoring, or other requirements, it will send a remote command. After receiving the command, the NB-10T communication module on control board 11 transmits it to the central processor. The central processor then sends the control signal to the valve control module on control board 11. The valve control module controls the opening or closing of the electrically controlled valves 4 on the gas inlet 2 and gas outlet 3 according to the command, thereby controlling the gas supply. It can monitor the user's gas meter usage in real time and prevent gas theft, cheating, and other similar situations.

[0026] See Figure 2 The ultrasonic gas meter body 1 is equipped with a dry cell battery 9, and the main control box 7 is equipped with a lithium battery 10. The dry cell battery 9 provides power so that users can replace the battery themselves, while the lithium battery 10 provides backup power to ensure stable communication.

[0027] See Figure 2 The bottom wall of the ultrasonic gas meter body 1 is connected to a damping pad 12, and the other end of the damping pad 12 is connected to a foot 8. The foot 8 is made of rubber, which can reduce the vibration and noise generated when the gas meter is working, and at the same time has a certain buffering effect on external vibration.

[0028] It should be noted that the ultrasonic gas meter body 1 is equipped with a dual switch, which controls the gas meter valve to protect the user's safety. The device also has a multi-level tiered gas pricing function, which can realize remote online price adjustment. It can also be equipped with an IC card prepayment module, which inherits the advantages of traditional IC card diaphragm gas meters, making it convenient and fast.

[0029] Working Principle: In terms of gas metering, when gas flows within the ultrasonic gas meter body 1, the ultrasonic transducer on the outer wall of the main control box 7 emits and receives ultrasonic signals. The ultrasonic metering module on the control board 11 accurately calculates the gas flow rate based on parameters such as the time difference of ultrasonic waves propagating in the gas and transmits the data to the central processor. The central processor processes and analyzes this data and then sends the gas usage information to the counter 6. The counter 6 records the cumulative gas usage and displays it intuitively to the user through the LCD screen 5. During data transmission, the central processor transmits the processed gas metering data and other relevant information wirelessly through a signal connection with the NB-10T communication module on the control board 11, enabling remote data transmission. This facilitates data collection and management for gas companies. The NB-10T technology offers fast connection speed, good signal penetration, low power consumption, and accurate and rapid meter reading. The system allows for customized remote meter reading, and the NB-10T uses a dedicated communication frequency band, providing strong anti-interference capabilities, stable communication signals, and high carrying capacity to avoid communication congestion. When the gas company needs to control the gas supply based on user payment status, safety monitoring, or other requirements, it will send remote commands. The NB-10T communication module on control board 11 receives the commands and transmits them to the central processor. The central processor then sends control signals to the valve control module on control board 11. The valve control module controls the opening or closing of the electrically controlled valves 4 on the inlet 2 and outlet 3 according to the commands, thereby controlling the gas supply. It can monitor the user's gas meter usage in real time, preventing gas theft and cheating. The dry cell battery 9 inside the ultrasonic gas meter body 1 and the lithium battery 10 inside the main control box 7 provide power for the entire system. The damping pad 12 and foot 8 connected to the bottom wall of the ultrasonic gas meter body 1 reduce the vibration and noise generated during gas meter operation.
