[0021] See also Figure 1 , is a handheld vibrating string collector in an embodiment of the present utility model, including a collector body, a Bluetooth module and a temperature sensor 21.

[0022] Among them: the temperature sensor 21 is built into the vibrating string sensor 20. The temperature sensor 21 adopts a digitally coded temperature sensor 21, which has a unique identification code of the corresponding vibrating string sensor 20 built in. The model of the temperature sensor 21 is DS18B20. The data acquisition instrument body includes a vibrating string excitation acquisition circuit 11, a microcontroller unit 13 and a FLASH memory 16. The vibrating string excitation acquisition circuit 11 and the FLASH memory 16 are both connected to the microcontroller unit 13. The FLASH memory 16 is used to store configuration information of multiple vibrating string sensors 20, such as initial frequency values, modulus coefficients and other parameters. The model of the FLASH memory 1616 is AT45DB161E. The temperature sensor 21 is connected to the microcontroller unit 13 via a Bluetooth module, and the vibrating string excitation acquisition circuit 11 is connected to the vibrating string sensor 20.

[0023] It should be noted that the vibrating string excitation acquisition circuit 11 provides a vibrating string excitation signal and can acquire the vibrating string signal of the vibrating string sensor 20, thereby acquiring the current frequency value of the vibrating string sensor 20. The identification code built into the temperature sensor 21 can be transmitted to the microcontroller unit 13 via the Bluetooth module, so that the microcontroller unit 13 can obtain the configuration information of the corresponding vibrating string sensor 20, such as the initial frequency value, modulus coefficient, and other parameters, from the FLASH memory 16 based on the identification code. The microcontroller unit 13 then automatically calculates the required physical quantities, thereby realizing the automatic calculation operation of the physical quantities.

[0024] In this embodiment, the Bluetooth module includes a first Bluetooth 14 and a second Bluetooth. The first Bluetooth 14 is connected to the microcontroller unit 13 via a UART, and the second Bluetooth is connected to the temperature sensor 21. The first Bluetooth 14 and the second Bluetooth perform wireless communication to transmit the identification code of the temperature sensor 21 to the microcontroller unit 13. It should be noted that if the acquisition device needs to be replaced, it is only necessary to connect the acquisition instrument with other vibrating string sensors 20 via Bluetooth and use the received identification code to obtain the configuration information of the corresponding vibrating string sensor 20 for performing corresponding calculation operations, thereby realizing automatic query of the required data and eliminating the tedious operation of manual input.

[0025] It should be noted that before the handheld vibrating string data collector is put into operation, the sensor modulus coefficient, initial value and other parameters of each vibrating string sensor 20 and the corresponding identification code are pre-stored in the FLASH memory 16. When calculating the corresponding physical quantity, the configuration information of the corresponding vibrating string sensor 20 in the FLASH memory 16 can be read through the microcontroller unit 13 based on the identification code.

[0026] In this embodiment, the vibrating string excitation acquisition circuit 11 is used to generate a vibrating string excitation signal and to process the signal of the vibrating string sensor 20. The vibrating string excitation acquisition circuit 11 is connected to the microcontroller unit 13 via an IO port. The IO port is provided on the microcontroller unit 13 and serves as an ADC input port of the microcontroller unit 13. The output of the vibrating string excitation acquisition circuit 11 is connected to the ADC input port of the microcontroller unit 13.

[0027] In this embodiment, the microcontroller 13 is a single chip microcomputer of model GD32F105VCT6. The microcontroller 13 is programmed with calculation formulas for calculating various physical quantities. The microcontroller 1313 is used to calculate corresponding physical quantities according to different calculation formulas.

[0028] In this embodiment, the collector body further includes a lithium battery power supply 15 , which is used to power various components of the handheld vibrating string collector. The lithium battery power supply 15 is connected to the micro control unit 13 .

[0029] In this embodiment, the handheld vibrating string collector also includes a display screen 17 and an input button 18. Both the display screen 17 and the input button 18 are connected to the microcontroller unit 13. The display screen 17 is used to realize data display and menu display, and the input button 18 is connected to the microcontroller unit 13 through the IO port.

[0030] In a specific implementation, a temperature sensor 21 is built into the vibrating string sensor 20, and an identification code of the vibrating string sensor 20 is provided in the temperature sensor 21. The temperature sensor 21 is connected to the microcontroller unit 13 in the data acquisition instrument body via a Bluetooth module. The FLASH memory 16 and the vibrating string excitation acquisition circuit 11 are respectively connected to the microcontroller unit 13, and the vibrating string excitation acquisition circuit 11 is connected to the microcontroller unit 13, so that the identification code of the vibrating string sensor 20 can be sent to the microcontroller unit 13 via the Bluetooth module. The microcontroller unit 13 obtains the corresponding configuration information of the vibrating string sensor 20 from the FLASH memory 16 based on the identification code, collects the current frequency value of the vibrating string sensor 20 via the vibrating string excitation acquisition circuit 11, and sends the collected current frequency value to the microcontroller unit 13. The microcontroller unit 13 then automatically calculates the required physical quantity, thereby realizing automatic calculation of the physical quantity and improving overall work efficiency.
