Description

Technical Field

[0001] This utility model relates to the field of remote calibration and testing technology for metering devices, specifically a remote calibration and testing device for metering devices with good signal transmission. Background Technology

[0002] As the name suggests, a metering device is a device that weighs products and controls the quantity of products during transportation. The metering accuracy of the metering device directly affects the stable operation of the production line. Therefore, it is necessary to use a calibration and testing device to calibrate the metering device when it is in operation.

[0003] However, the signal transmission of existing remote calibration and testing equipment for metering devices is unstable and prone to packet loss, which can lead to the loss of metering data. Therefore, there is a need for a remote calibration and testing equipment for metering devices with better signal transmission. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a remote verification and testing device for a metering device with good signal transmission, including a metering device body 1, a verification and testing mechanism 2 is provided on one side of the metering device body 1, the verification and testing mechanism 2 is connected to a signal transmitting mechanism 3, the signal transmitting mechanism 3 includes a first signal transmitter 4, a second signal transmitter 5, and a third signal transmitter 6, a first antenna 7 is provided on the first signal transmitter 4, a second antenna 8 is provided on the second signal transmitter 5, and a third antenna 9 is provided on the third signal transmitter 6, the first signal transmitter 4, the second signal transmitter 5, and the third signal transmitter 6 are all mounted on a fixed frame 10, the included angle between the first antenna 7 and the second antenna 8 is 60°, and the included angle between the second antenna 8 and the third antenna 9 is 75°.

[0022] Specifically, the verification and testing mechanism 2 includes a data processing module 11 and a signal conversion module 12. The data processing module 11 is connected to the metering device body 1. The input end of the signal conversion module 12 is electrically connected to the data processing module 11. The output end of the signal conversion module 12 is electrically connected to the first signal transmitter 4, the second signal transmitter 5, and the third signal transmitter 6, respectively. Through the above settings, the signal conversion module 12 can convert the data processed by the data processing module 11 into a signal format suitable for transmission and transmit it through the three signal transmitters to ensure the stability and reliability of signal transmission.

[0023] Specifically, signal amplifiers 13 are installed at the top of the first antenna 7, the second antenna 8, and the third antenna 9. By installing signal amplifiers 13, the signal can be enhanced during transmission, thereby improving the signal coverage and penetration. The use of signal amplifiers 13 can also reduce signal attenuation during transmission, ensuring the signal transmission quality of remote verification and testing equipment.

[0024] Specifically, a fixing sleeve 14 is provided at the connection between the first antenna 7 and the first signal transmitter 4, a fixing sleeve 14 is also provided at the connection between the second antenna 8 and the second signal transmitter 5, and a fixing sleeve 14 is also provided at the connection between the third antenna 9 and the third signal transmitter 6. Furthermore, a suction cup 15 is provided at the bottom of the fixing sleeve 14, and a sealing ring 16 is provided at the connection between the fixing sleeve 14 and the suction cup 15. The fixing sleeve 14 and the suction cup 15 ensure the stability of the antenna and prevent the antenna from shifting, thereby ensuring the quality of the transmitted signal. The sealing ring 16 prevents rainwater from entering the connection between the signal transmitter and the antenna in bad weather, which could damage the equipment.

[0025] Specifically, the first antenna 7 emits a signal in the 2.4GHz frequency band, the second antenna 8 emits a signal in the 5GHz frequency band, and the third antenna 9 emits a signal in the 900MHz frequency band. By setting up signal transmitters in different frequency bands, interference between signals can be effectively avoided, and the stability and reliability of signal transmission can be improved.

[0026] A specific application example of this embodiment is as follows:

[0027] In use, the measuring device 1 is first used for measurement. Then, the data processing module 11 collects and analyzes the measurement data of the measuring device 1 in real time. The signal conversion module 12 converts the processed data into a signal format suitable for transmission, such as converting digital signals into radio frequency signals. The converted signals are transmitted through the first antenna 7, the second antenna 8, and the third antenna 9. Since the three antennas operate at different frequency bands, they can work simultaneously. The angle between the first antenna 7 and the second antenna 8 is 60°, and the angle between the second antenna 8 and the third antenna 9 is 75°. This configuration ensures the stability of the transmitted signal and minimizes mutual interference between the three antennas, thus achieving stable transmission of multi-channel signals. At the receiving end, the corresponding signal receiver can accurately receive and decode these signals to complete remote verification and detection. The use of the signal amplifier 13 ensures that the signal strength and quality are guaranteed even when the signal transmission distance is long.
