[0040] This charging device of the telemetry implant device has the following beneficial effects: The telemetry implant device has a wireless charging function, which means that it is not necessary to frequently remove and replace the battery 13 from the animal body, reducing the interference and stress response to the animal.

The charging control box 1 can control the wireless power supply transmitting unit 2 to charge the telemetry implant device. This intelligent control can optimize the charging process, improve the energy conversion efficiency, and reduce energy waste at the same time.

[0041] Specifically, the charging control box 1 includes: a microcontroller 11, a battery 13 and a drive circuit 12; the drive circuit 12 is respectively connected to the microcontroller 11, the battery 13 and the wireless power supply transmitting unit 2; the microcontroller 11 is used to control the battery 13 to supply power to the wireless power supply transmitting unit 2 through the drive circuit 12, so that the wireless power supply transmitting unit 2 charges the telemetry implant device.

[0042] Among them, the microcontroller 11 is the intelligent control center, responsible for processing various instructions and data during the charging process. It realizes precise control of the power supply to the battery 13 through programming, ensuring that the wireless power transmission unit 2 charges the telemetry implant device at an appropriate power.

[0043] The battery 13 provides the required electrical energy for the charging control box 1 and is the energy source of the entire charging device. The selection of the battery 13 needs to consider its capacity, discharge characteristics, and safety to meet the requirements of long-term power supply and stable output.

Specifically, the data storage module 15 can be an EEPROM data memory, which is used to record the device information of the charging device itself, such as SN, etc., and at the same time, this memory also records the network parameters related to wifi.

[0051] Furthermore, the charging control box 1 further includes a power detection unit respectively connected to the microcontroller 11 and the battery 13, which is used to detect the power information of the battery 13.

[0056] Further, referring to Figure 2 The present utility model also provides a telemetry implant device, including: a telemetry implant device main body 31 and a wireless charging unit 32; the wireless charging unit 32 is used to cooperate with a preset charging device of the telemetry implant device to achieve charging of the telemetry implant device main body 31.

[0058] In practical applications, the wireless charging unit 32 is designed according to the requirements of the preset charging device to ensure compatibility and efficient energy transfer between the two.

[0059] Further, the body 31 of the telemetry implant device includes a wireless communication unit 311; the wireless communication unit 311 is used for communicating with the charging device corresponding to the telemetry implant device.

[0060] Among them, the wireless communication unit 311 can adopt Wi-Fi, Bluetooth or radio frequency technology to realize wireless connection with the charging device. The wireless communication unit 311 is not only used to receive control signals from the charging device, but also used to send the status information of the device to the charging device to achieve two-way communication. Through the wireless communication unit 311, the telemetry implant device can exchange data with the charging device, including but not limited to battery level, temperature reading, device status, etc.

[0061] Further, the telemetry implant device further includes a temperature sensor 33 electrically connected to the telemetry implant device, which is used to detect the temperature of the wireless charging unit 32. The temperature sensor 33 provides real-time temperature feedback to ensure that the temperature of the wireless charging unit 32 is within a safe range during the charging process and avoid overheating. In this way, the charging device can receive this data through the wireless communication unit 311 according to the data provided by the temperature sensor 33 and intelligently adjust the charging power to control the temperature. The real-time temperature monitoring and intelligent adjustment mechanism helps to optimize the charging process, improve the charging efficiency, and ensure the safety of the device and the animal at the same time.

[0062] The following combines a specific embodiment to illustrate the solution provided by the present invention. The present invention provides a charging device suitable for a telemetry implant device, which has the following features: (1) adopts an external wireless charging technology to solve the problem of insufficient battery life of the telemetry implant device; (2) the charging device can be installed on the animal body to achieve in-vivo charging; (3) can dynamically adjust the charging power to balance the charging time and the problem of coil heating; (4) has a wireless power supply capacity of 50 mm to adapt to the implantation depth of the implant device in different animals.

[0063] Specifically, the charging device of the telemetry implant device (abbreviated as the charging device) consists of three parts: a charging control box 1, a wireless power supply transmitting unit 2, and a backpack-type animal vest (wearable structure). During use, the charging control box 1 and the wireless power supply transmitting unit 2 are placed inside the backpack-type animal vest, the vest is worn on the experimental animal, and the position of the wireless power supply transmitting unit 2 is adjusted. The charging control box 1 is connected to the wireless power supply transmitting unit 2 through an internal cable.

[0064] An internal wifi communication unit is designed in the charging device, which is connected to the microcontroller 11 through a serial communication interface. Through the wifi unit, the microcontroller 11 can establish a connection with the gateway and transmit data. During the charging process, the telemetry implant device collects the rectified voltage, charging current, and device temperature information on the coil and transmits this information to the gateway. The gateway transmits the data to the charging device through the internal wifi communication unit of the gateway, and then the charging device dynamically adjusts the wireless charging power according to this information.

[0065] A programmable power supply module is designed inside the charging device. The voltage value output by the 12-bit DAC built in the microcontroller 11 is applied to the negative feedback pin of the programmable power supply module. Through the action of negative feedback, the programmable power supply module can change the output voltage, and this voltage is used to drive the wireless power supply transmitting unit 2, and the transmitting power of the wireless power supply is adjusted by changing the driving voltage.

[0066] Specifically, the wireless power supply transmitting unit 2 is composed of an inductance coil, a resonant capacitor, and a driving circuit 12. The power supply coil and the resonant capacitor form a resonant system. Under the action of the driving circuit 12, the direct current output by the programmable power supply module is adjusted to an alternating current and applied to the resonant system to generate an alternating magnetic field, thereby transmitting electrical energy through the coil. At the receiving end, the alternating magnetic field acts on the same resonant system to generate alternating electrical energy, and through rectification, voltage stabilization and other measures, electrical energy that can be used is generated at the receiving end.

[0067] Due to the adoption of wireless power supply technology, the energy receiving coil and the resonant capacitor will cause heating problems under the action of high-frequency current. Severe heating will cause discomfort to animals and even cause inflammation. At the same time, it is necessary to ensure a certain amount of energy to meet the system working requirements. The advantage of this device is to add a feedback path in the whole system, that is, to transmit the voltage, current, temperature and other information of the receiving end of the telemetry implant device to the external gateway in real time, and the gateway then transmits this information to the corresponding charging device. The charging transmitting device will adjust the size of the transmitted energy according to the received information, so as to strictly limit the heating condition while meeting the system power consumption requirements.

[0068] Specifically, before implementation, information such as the experimental animal number, the telemetry implant device number (already implanted in the animal), and the charging device number needs to be recorded and associated on the experimental platform.

[0069] First, attach the coil part of the wireless power transmission unit 2 to the animal's body, positioning it as directly as possible opposite the receiving coil of the telemetry implant device to improve coupling and energy transmission efficiency. Then, put the vest on the animal's body and wrap the wireless power transmission unit 2 well. Next, place the charging control box 1 in the pocket on the back of the vest, connect the cables, and turn on the device. Then, search for the device on the platform and wait for the gateway to connect and pair with the telemetry implant device and the charging device. After the pairing is complete, charging can be started.

[0070] In some embodiments, when the telemetry implant device is in a power-depleted standby state and cannot connect to the gateway, the charging device will activate the low-power charging mode to charge at a relatively low charging power to avoid the problem of overheating of the telemetry implant device. When the power of the telemetry implant device is restored and the device is in a working and networked state, the normal charging mode can be resumed.
