[0027] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0028] refer to Figure 2 There is a vacuum area 310 to be measured inside the vacuum insulation panel or vacuum glass 300. The collection device 200 is arranged in the vacuum area 310 of the vacuum product and can be fixed on the inner surface of the upper layer or the lower layer, such as Figure 2 As shown, it is arranged on the inner surface of the upper layer. When the vacuum degree measuring device 100 is close to the acquisition device 200, it can transmit alternating current and data signals to the acquisition device 200. Through the cooperation of the vacuum degree measuring device 100 and the acquisition device 200, the vacuum degree of the vacuum area 310 to be measured can be accurately measured. Avoid air leakage of the vacuum insulation panel or vacuum glass 300 due to the interface of the lead wire, thereby destroying the performance of the vacuum insulation panel or vacuum glass.

[0029] refer to Figure 1, this embodiment provides a vacuum degree measuring device 100, which is used to communicate with a collection device 200 installed in a vacuum insulation panel or vacuum glass 300. The vacuum degree measuring device 100 includes: a control module 110 and a power supply module 120, a two-way communication module 130, a code scanning module 140 and a display module 190 electrically connected to the control module 110, respectively, and the two-way communication module 130 is wirelessly connected to the collection device 200. Among them, the power supply module 120 is used to supply power to the control module 110, and the code scanning module 140 is used to obtain product information of the product to be tested and send the product information to the control module 110. The control module 110 is used to control the two-way communication module 130 to send a collection instruction to the collection device 200 and receive real-time data sent by the collection device 200, and control the display module 190 to display product information and the vacuum degree of the vacuum area 310 to be tested of the corresponding product, and the vacuum degree is obtained by the control module 110 according to the real-time data.

[0030] It should be noted that the control module 110 can be a single-chip microcomputer, which uses very large-scale integrated circuit technology to integrate a central processing unit CPU with data processing capabilities, random access memory RAM, read-only memory ROM, multiple I / O ports and interrupt systems, timer / counters and other functions (which may also include display drive circuits, pulse width modulation circuits, analog multiplexers, A / D converters and other circuits) into a silicon chip to form a small and complete microcomputer system.

[0031] In one example, the power supply module 120 includes a USB interface 121, a power management module 122, and a rechargeable battery 123. The USB interface 121 is electrically connected to the power management module 122 and the control module 110, respectively, and the rechargeable battery 123 is connected between the power management module 122 and the control module 110. When the USB interface 121 is connected to an external power source, the control module 110 receives a high-level signal transmitted from the USB interface 121, and the control module 110 can control the USB interface 121 to start powering the control module 110, and control the rechargeable battery 123 to stop powering the control module 110, and the circuit uses the USB interface 121 for power supply first.

[0032] It should be noted that the control module 110 controls the function of the USB interface 121 to supply power or the rechargeable battery 123 to supply power. The implementation method may be: a switch element (MOS tube) is connected between the control module 110 and the USB interface 121 and the rechargeable battery 123, and the control module 110 determines whether the USB interface 121 is connected to an external power source. If the external power source is connected, the control module 110 outputs a high-level signal to turn on the MOS tube connected to the USB interface 121 and turn off the MOS tube connected to the rechargeable battery 123 to realize the power supply of the USB interface 121; otherwise, the rechargeable battery 123 supplies power. When the USB interface 121 supplies power, the rechargeable battery 123 can be charged through the cooperation of the USB interface 121 and the power management module 122. In addition, the USB interface 121 can also be connected to the PC end, so as to realize the communication between the PC end and the single-chip microcomputer.

[0033] In one example, the bidirectional communication module 130 includes a modulation circuit module 131 , a demodulation circuit module 132 and a coil winding 133 , wherein the output end of the modulation circuit module 131 is electrically connected to the coil winding 133 , and the input end of the demodulation circuit module 132 is electrically connected to the coil winding 133 .

[0034] Among them, the coil winding 133 and the coil in the acquisition device 200 are connected in a magnetic field coupling manner, and non-contact transmission of data signals and AC signals can be achieved between them. After receiving the acquisition instruction signal of the vacuum degree measuring device 100, the acquisition device 200 can measure the vacuum degree of the vacuum area 310 to be measured according to the acquisition instruction, thereby obtaining real-time data of the vacuum area 310 to be measured (real-time data may include measurement parameters, vacuum degree, etc. If it is a measurement parameter, the measurement parameter needs to be calculated and processed in the vacuum degree measuring device 100 to obtain the vacuum degree value; if it is vacuum degree, there is no need to calculate and process data in the vacuum degree measuring device 100). It should be noted that the acquisition device 200 is a prior art and will not be described in detail here.

[0035] After the control module 110 outputs a DC signal and an acquisition instruction to the modulation circuit module 131, the modulation circuit module 131 converts the DC signal into an AC signal of a fixed frequency, and uses the frequency of the AC signal as the base frequency of the carrier, modulates the high-frequency data signal (including the acquisition instruction) and superimposes it on the frequency band to form a new carrier signal, which is wirelessly transmitted to the acquisition device 200 through the coil winding 133.

[0036] The demodulation circuit module 132 can demodulate the carrier signal sent back by the acquisition device 200 to obtain real-time data of measurement. The control module 110 can obtain the vacuum degree of the vacuum area 310 to be measured according to the real-time data.

[0037] The combination of wireless power supply and data transmission can avoid air leakage of the vacuum insulation panel or vacuum glass 300 due to the interface of the lead wire, which causes the vacuum insulation panel or vacuum glass to fail in its proper performance.

[0038] In one example, the vacuum degree measuring device 100 includes a key module, which is electrically connected to the control module 110. The key module can be used to adjust the parameters of the detection, the real-time clock, the server IP of the 4G / 5G module, and other parameters, as well as input parameter signals of the vacuum degree detection. The control module 110 generates a collection instruction according to the parameter signal and outputs it to the collection device 200.

[0039] For example, the key module includes key 1 and key 2. When the vacuum degree is measured, key 1 and key 2 are used to adjust the magnification and reduction of the amplifier in the acquisition device 200, respectively. After key 1 and key 2 are connected in series with resistor 1 and resistor 2, they are connected to the input pin of the single-chip microcomputer, and the other ends of key 1 and key 2 are connected to the ground terminal. At the same time, key 1 and key 2 are respectively adapted to resistor 1 and resistor 2, and the resistance value between resistor 1 and resistor 2 is an increasing or decreasing relationship. Pressing the key turns on the circuit, and the voltage divider value of different resistor values ​​is different. The voltage divider value is compared with the preset voltage value output by the DAC unit in the single-chip microcomputer through the comparator in the single-chip microcomputer, and the key can be identified, and it is identified that key 1 or key 2 is pressed.

[0040] The vacuum degree measuring device 100 includes a clock module 150 , a storage module 160 , a Bluetooth module 170 and a network module 180 , and the control module 110 is electrically connected to the clock module 150 , the storage module 160 , the Bluetooth module 170 and the network module 180 , respectively.

[0041] The clock module 150 is used to synchronize with the clock of the acquisition device 200 and provide timing and timing functions for the measurement and communication of the acquisition device 200. In addition to providing a stable time reference signal for the circuit, the clock module 150 can also be used to synchronize data transmission and processing. For example, data is usually transmitted and processed in the form of a time sequence, and the rising edge or falling edge of the clock signal is used to determine the sampling and transmission timing of the data, thereby ensuring the accuracy and reliability of the data.

[0042] The storage module 160 is used to store product information and the measurement parameters and vacuum degree of the corresponding product. For example, the production date, production machine and customer information on the vacuum insulation panel or vacuum glass 300 are generated into a barcode or a QR code attached to the product. During the vacuum degree measurement process, the product information is first read using the code scanning module 140, and then the product information, the sensor ID sent back by the acquisition device 200, the vacuum pressure value test result, the measurement time and other information are correspondingly saved in the database for subsequent query and tracing.

[0043] The Bluetooth module 170 is used for data transmission between the control module 110 and the host computer. The vacuum degree measuring device 100 can be connected to the PC or mobile phone via the Bluetooth module 170. The circuit measurement parameters can be configured, the historical results of vacuum pressure value measurement can be queried, and the data can be exported through PC software or mobile phone app.

[0044] The network module 180 is used for data transmission between the control module 110 and the server. The vacuum degree measuring device 100 can send the product information of the vacuum insulation panel or vacuum glass 300, the measurement time and the measurement results to the cloud server through the 4G / 5G network. The cloud server stores the information in the cloud database, and the user can remotely query the vacuum pressure value information of a certain product.

[0045] The working process of the vacuum degree measuring device 100 may be:

[0046] After the vacuum degree measuring device 100 is powered on, the overall initialization begins, and then the self-test of each functional module is turned on (whether the battery power, storage module 160, communication module, etc. are normal), and the result of the self-test is displayed on the display module 190. The operation button adjusts the clock module 150 to be consistent with the current time. Scan the barcode or QR code of the vacuum insulation panel or vacuum glass 300 to read the product information. The coil winding 133 is aligned with the coil of the acquisition device 200, and the position is adjusted to adjust the signal strength to greater than 50%. The parameters of the vacuum degree measurement are set by pressing the button. If the PC or mobile phone is connected to the Bluetooth module 170, the time and measurement parameters can also be set in the PC software or mobile phone app. The parameters of the vacuum measurement are sent to the acquisition device 200 through the coil winding 133, and a start measurement instruction is issued. After the acquisition device 200 completes the measurement, the vacuum sensor ID and measurement results returned by the acquisition device 200 are packaged into a data packet together with the product information scanned by the code scanning module 140 and saved in the storage module 160. At the same time, the microcontroller sends the data packet to the cloud server through the 4G / 5G module, so that users can remotely query the measurement results of the product.
