Description

Technical Field

[0001] The utility model relates to the technical field of detectors, in particular to an electric control module of a detector and the detector. Background Art

[0002] With the development and widespread adoption of continuous blood glucose monitoring technology, the demand for miniaturization and intelligentization is growing stronger. Data interaction with mobile phones has significantly improved the convenience and efficiency of its use. Using Bluetooth low-power wireless connection technology, blood glucose data collected by continuous blood glucose monitors can be uploaded to mobile phones or other devices in real time, making it possible to analyze and manage blood glucose levels using big data technology.

[0003] However, due to the requirement of comfort, the size of continuous blood glucose monitors is developing towards miniaturization, and the requirements for antennas continue to increase. It is particularly important to ensure the transmission efficiency of the antenna as much as possible while reducing the size.

[0004] Furthermore, wearable continuous glucose monitoring systems, in particular, are required to be as small as possible and operate for extended periods of time, typically exceeding 14 days. However, since antennas require larger dimensions to achieve better radiation, this contradicts the miniaturization requirements of continuous glucose monitoring systems. Furthermore, antenna efficiency directly impacts system power consumption, and improving antenna radiation efficiency ensures longer operating times. This complicates antenna design.

Unless otherwise specified, "plurality" means two or more.

[0036] See also Figure 1 and Figure 3 , Figure 1 and Figure 3 The diagrams are partial structural diagrams of two shapes of the detector 100 provided in the embodiment of the present invention. It is understood that the detector 100 is also equipped with other components (not shown in the figure), such as a probe, a bracket, an elastic member, a pressing member, a sealing member, etc. Of course, the detector 100 can be specifically designed according to the specific application scenario and may not include the components not shown in the above figures. Since the components not shown in this part of the figure are not the key innovative technical points of this application, they will not be described in detail in this embodiment, nor will they be shown in the figures.

[0037] The detector 100 is a blood glucose detector for measuring the blood glucose level of a user or patient. The detector 100 can also be a continuous blood glucose detector, which is worn on a certain part of the user's or patient's body for continuous monitoring, data analysis, and management.

[0038] Specifically, see Figure 2 , Figure 2 Shown Figure 1 The three-dimensional exploded view of the detector 100 shown. In this embodiment, the detector 100 includes a shell 2 and an electric control module 1 arranged in the shell 2, as well as a sensor unit 3 and a probe 4. The probe 4 is used to penetrate the sampling site to obtain a sample, and obtain the original data in the sample through the sensor unit 3 or transmit the sample to the electric control module 1 for processing, conversion and transmission. In this embodiment, the shell 2 includes an upper shell component 21 and a lower shell component 22. The upper shell component 21 and the lower shell component 22 are enclosed to form a cavity. The electric control module 1, the sensor unit 3 and the probe 4 are all arranged in the cavity. Since the shell 2 is not an innovative design point of the embodiment of the present application, it will not be described here.

[0039] See also Figure 3 , Figure 3 It is a partial structural diagram of another detector 100 provided in an embodiment of the present utility model. In this embodiment, the detector 100 may not include a probe. The detector 100 can be worn directly on a certain part of the body of the user or patient to continuously monitor their blood sugar, and transmit the monitoring data to the electronic control module 1 through the sensor unit 3 for processing, conversion and transmission. In this embodiment, the detector 100 includes a shell 2 and an electronic control module 1 arranged in the shell 2, and the electronic control module 1 processes, converts and transmits the collected raw data. The detector may also include a sensor unit 3, which is used to obtain relevant raw data such as blood sugar, and transmit it to the electronic control module 1 for processing, conversion and transmission.

[0040] Among them, the electronic control modules 1 in the aforementioned embodiments can be connected to external devices such as mobile phones, tablets, computers and other electronic devices, and process, convert and transmit blood glucose detection data to external devices, thereby facilitating subsequent big data analysis and organization, and facilitating the user's blood glucose level management.

[0041] Combine Figure 1 and Figure 2 It can be seen that the specific structure and appearance of the housing 2 of the detector 100 are designed according to product design requirements. Figure 1 and Figure 3 The shape of the housing 2 shown in FIG. 1 is only a schematic diagram for ease of understanding.

[0042] Since the application scenarios of the detector 100 are different, the internal structure is also different, and other components are not the key innovative technical points of the embodiment of the present application. Therefore, the embodiment of the present application will be described in detail below with reference to the accompanying drawings for the key innovative part of the electronic control module 1 of the embodiment of the present application.

[0043] See also Figure 4 , is a three-dimensional diagram of the electric control module 1 of the detector 100 provided in an embodiment of the present application. As a part of the detector 100, the electric control module 1 includes a circuit board, specifically a printed circuit board 16. Other components of the electric control module 1 are all arranged on the printed circuit board 16. The detector 100 includes a sensor unit 3, which is used to transmit the raw data related to the blood sugar of the user or patient, etc., collected by the detector 100, to the electric control module 1 for processing. The printed circuit board 16 has a first mounting portion 161 for setting the sensor unit 3. The first mounting portion 161 is a hole that passes through the printed circuit board 16.

[0044] Specifically, see Figure 5 and Figure 6 The electronic control module 1 includes a detection unit 11, a wireless communication control unit 12, a matching network unit 13, and a ceramic antenna 14. The detection unit 11, the wireless communication control unit 12, the matching network unit 13, and the ceramic antenna 14 are all arranged on the printed circuit board 16.

[0045] Among them, the detection unit 11 is used to process the original data output by the sensing unit 3 to obtain detection data; the wireless communication control unit 12 is electrically connected to the detection unit 11, used to receive the detection data and output a radio frequency signal; the matching network unit 13 is electrically connected to the wireless communication control unit 12, used to receive the radio frequency signal and perform network impedance matching; the ceramic antenna 14 is electrically connected to the matching network unit 13, used to receive the radio frequency signal after network impedance matching when the matching network unit 13 reaches a matching state for wireless transmission.

[0046] Compared with the existing technology, the electronic control module 1 provided in this application realizes the processing, conversion and transmission of detection data to an external interactive device through the connection and cooperation of the detection unit 11, the wireless communication control unit 12, the matching network unit 13 and the ceramic antenna 14, thereby realizing efficient data processing, wireless communication and data transmission, and facilitating the analysis and management of big data; and adopts a ceramic antenna 14 with a small size characteristic to further reduce the overall size of the detector 100, thereby miniaturizing the product.

[0047] Specifically, the ceramic antenna 14 is a chip ceramic antenna, specifically the ANT016008LCS2442MA2; it comes in a 1608 package. 1608 refers to the size code for standardized electronic components; specifically, "16" indicates a length of 1.6 mm, and "08" indicates a width of 0.8 mm. The 1608 package allows the antenna to be seamlessly integrated into the device's compact design while maintaining excellent wireless communication performance. Its standardized size makes it suitable for automated SMT (surface mount technology) assembly processes, further reducing production costs.

[0048] The wireless communication control unit 12 includes a Bluetooth communication chip; the Bluetooth communication chip is a BLE Bluetooth communication chip. The BLE Bluetooth communication chip is compact, further reducing the product's design size. Specifically, the low-power BLE Bluetooth communication chip enables stable and convenient wireless data transmission, operating with low energy consumption, thereby extending the device's battery life.

[0049] In this embodiment, the ceramic antenna 14 is surrounded by an antenna clearance zone 1a. This zone 1a refers to the space between the antenna and surrounding objects, and is crucial to antenna performance. This zone 1a ensures sufficient clearance for the antenna to avoid shielding or interference, ensuring omnidirectional communication. Providing this zone 1a around the ceramic antenna 14 minimizes signal obstruction, thereby improving signal transmission quality and coverage.

[0050] The distance between the ceramic antenna 14 and the copper-clad area on the printed circuit board 16 where the ceramic antenna 14 is located is greater than or equal to 0.70 mm, the distance between the ceramic antenna 14 and the outer edge of the printed circuit board 16 is greater than or equal to 1.0 mm, and the distance between the ceramic antenna 14 and other component areas on the printed circuit board 16 is greater than or equal to 0.3 mm. The copper-clad area on the printed circuit board 16 is also called the copper-clad area or ground layer. Limiting the distance between the copper-clad area on the printed circuit board 16 where the ceramic antenna 14 is located can avoid affecting signal radiation performance. At the same time, sufficient spacing (at least 0.3 mm and 1.0 mm) is maintained between the ceramic antenna 14 and the outer edge of the printed circuit board 16 and other component areas, thereby optimizing the circuit board layout and signal transmission, avoiding potential interference, enhancing the stability of the antenna and the overall electromagnetic compatibility, and ensuring the performance and safety of the radio communication equipment.

[0051] Furthermore, the electronic control module 1 also includes a crystal oscillator element 15, which is electrically connected to the wireless communication control unit 12 and is used to provide a basic clock for the wireless communication control unit 12; specifically, in this embodiment, the crystal oscillator frequency of the crystal oscillator element 15 is 32MHz. Among them, the crystal oscillator element 15 is fully called a crystal oscillator (Crystal Oscillator), which is an electronic component that uses the piezoelectric effect of a quartz crystal to generate a stable frequency oscillation. The crystal oscillator element 15 plays the role of providing a clock signal in an electronic device and is a key component to ensure the normal operation of the device.

[0052] The detection unit 11 is used to transmit the detection data to the wireless communication control unit 12 through the SPI / I2C / UART or GPIO interface. Among them, SPI (Serial Peripheral Interface), I2C (Inter-Integrated Circuit) and UART (Universal Asynchronous Receiver / Transmitter) and GPIO (General-Purpose Input / Output) are several commonly used interfaces and communication protocols in electronic systems. In this embodiment, the interface can adopt an SPI interface or an I2C interface or a UART interface or a GPIO interface. Which interface is specifically adopted in the product is selected according to the specific device communication requirements, and the embodiment of the present application does not make specific restrictions. The SPI / I2C / UART or GPIO interface is used to realize data interaction with the detection unit 11, thereby optimizing the detection data transmission efficiency and improving the overall performance and stability of the wireless communication system.

[0053] See also Figure 7 , Figure 7The circuit diagram of the matching network unit 13 of the electronic control module 1 in an embodiment of the present application is shown. Specifically, the matching network unit 13 is a π-type network. Specifically, the matching network unit 13 includes a first matching unit 131, a second matching unit 132, and a third matching unit 133. The second matching unit 132 is connected to the wireless communication control unit 12 and the ceramic antenna 14 at both ends. The first matching unit 131 is connected between the node between the wireless communication control unit 12 and the ceramic antenna 14 and ground. The third matching unit 133 is connected between the node between the wireless communication control unit 12 and the second matching unit 132 and ground. The first matching unit 131 is an inductor or capacitor, the second matching unit 132 is an inductor or capacitor, and the third matching unit 133 is an inductor or capacitor. It is understood that any one, two, or all of the first matching unit 131, the second matching unit 132, and the third matching unit 133 can be either inductors or capacitors, and this application does not limit this. Specifically, in this embodiment, first matching unit 131 is not soldered, second matching unit 132 is a capacitor (specifically, 33pF), and third matching unit 133 is an inductor (specifically, 2.2nH). By providing a π-type network between wireless communication control unit 12 and ceramic antenna 14, good transmission quality and stability of wireless communication signals are achieved, improving signal reception and transmission efficiency, enhancing wireless communication reliability, effectively reducing energy consumption, and minimizing the impact on other radio equipment.

[0054] Specifically, the matching network unit 13 and the wireless communication control unit 12 are electrically connected through a first microstrip line 1b formed on the printed circuit board 16, and the matching network unit 13 and the ceramic antenna 14 are electrically connected through a second microstrip line 1c formed on the printed circuit board 16. Microstrip is a form of transmission line commonly used in microwave and millimeter wave frequency bands. Its characteristic is that the electromagnetic field is mainly confined to a thinner dielectric layer, and the transmission and manipulation of electromagnetic waves are achieved through three basic parts: a patch, a ground plane, and a dielectric substrate. In this embodiment, the characteristic impedance of the first microstrip line 1b and the second microstrip line 1c is 50Ω. The electrical connection is achieved through microstrip lines, which simplifies the layout and wiring between the units, improves the stability of the circuit, reduces electromagnetic interference, optimizes frequency matching, and enhances the performance of wireless communication equipment.

[0055] In order to realize power supply, the electric control module 1 further includes a battery module 17 , and the battery module 17 is arranged on the printed circuit board 16 .

[0056] Since the detector 100 provided in the embodiment of the present application is used for blood glucose monitoring and requires irradiation sterilization, to protect the sensitive components in the electronic control module 1 from damage, the electronic control module 1 also includes a shielding assembly 18. The shielding assembly 18 is disposed on one side of the detection unit 11 and is used to block at least a portion of the radiation, thereby forming a full-shadow shielding area to protect the detection unit 11. The printed circuit board 16 has a second mounting portion 162 for mounting the shielding assembly 18. The shielding assembly 18 includes a shielding block 181 and / or a shielding bracket 182. The second mounting portion 162 is a hole extending through the printed circuit board 16. Specifically, in the embodiment of the present application, the shielding assembly 18 includes a shielding block 181 and a shielding bracket 182. The shielding bracket 182 is disposed on the second mounting portion 162 and supports the shielding block 181. The shielding block 181 is disposed above the detection unit 11, thereby forming a full-shadow shielding area to block radiation from one direction. The density of the shielding block 181 is greater than 1000 kilograms per cubic meter. The greater the density of the shielding block 181, the better the shielding block 181 blocks the radiation. The shielding block 181 can be in the form of a plate, a block, or other shapes, and this embodiment does not impose any specific limitations. In other embodiments, the shielding assembly 18 may include only the shielding block 181, as long as it can block and form a full-shadow shielding area. In other embodiments, a full-shadow shielding area can also be formed by the shielding bracket 182.

[0057] Specifically, the battery module 17, the shielding assembly 18, and the detection unit 11 are located in a straight line. The battery module 17 and the shielding assembly 18 are used to jointly block at least a portion of the radiation, thereby ensuring that the radiation in this direction is blocked. Of course, in other embodiments, only the battery module 17 can be used to shield the radiation.

[0058] The wireless communication control unit 12 is disposed in the full-shadow shielding area. The electronic control module 1 also includes a sensor unit connector 19, which is disposed on the printed circuit board 16 and electrically connects the sensor unit 3 to the detection unit 11. Providing a full-shadow shielding area effectively prevents damage to the detection unit 11 and the wireless communication control unit 12 from being exposed to radiation, thereby ensuring the accuracy of detection and the service life of the electronic control module 1.

[0059] To further reduce the size of the electronic control module 1 and thereby miniaturize the detector 100, in this embodiment, the printed circuit board 16 is circular, and the battery module 17, the first mounting portion 161, the sensor unit connector 19, the detection unit 11, the wireless communication control unit 12, the matching network unit 13, and the ceramic antenna 14 are sequentially arranged around the second mounting portion 162. This design makes the layout of the electronic control module 1 more compact and smaller in size.

[0060] The above is a detailed introduction to the detector and its electronic control module disclosed in the embodiment of the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the detector and its electronic control module and its core idea of the present invention; at the same time, for general technical personnel in this field, based on the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
