[0026] Figure 1A schematic block diagram of an integrated circuit 100 for electrical equipment according to an embodiment of the utility model is shown. The integrated circuit 100 includes an electrical module interface 101 for data interaction with the outside of the integrated circuit 100, a central processing unit 102 for data calculation and processing, and a wireless signal processing unit 103 for wireless data encoding and decoding processing and wireless communication protocol stack implementation. The electrical equipment may be, for example, a battery device, a charging device, an electric tool, etc., which is not limited by the utility model. For electrical equipment, people usually also need to control the start and stop of the electrical equipment, and also need to collect the working status of the electrical equipment in real time for monitoring and analysis, etc. Therefore, the electrical equipment also includes some peripheral electrical modules 110 located outside the integrated circuit 100.
[0027] In some embodiments, the electrical module interface 101 of the integrated circuit 100 is used to connect with the peripheral electrical module 110, so that the integrated circuit 100 can exchange data with the electrical module 110. If the electrical device is an electric tool as an example, the electrical module 110 may include a switch unit, a signal acquisition unit, a display unit, etc., and the data that the integrated circuit 100 can interact with the electrical module 110 include but are not limited to the start / stop signal, speed signal, temperature signal, overload signal, normal state / alarm state signal, etc. of the electric tool. If the electrical device is a battery device as an example, the electrical module 110 may include a charge and discharge control unit, a signal acquisition unit, a display unit, etc., and the data that the integrated circuit 100 can interact with the electrical module 110 include but are not limited to the charge / discharge signal, voltage signal, current signal, temperature signal, completion of charging signal, etc. of the battery device. In some embodiments, the electrical module 110 is arranged inside the electrical device, and the electrical module interface 101 is configured as a wired communication interface accordingly. The electrical module interface 101 may be configured as a half-duplex or full-duplex communication interface according to the energy consumption requirements of the electrical device and the efficiency and reliability requirements of the data interacting between the integrated circuit 100 and the electrical module 110. In some embodiments, based on the requirement that the real-time performance of controlling and monitoring the electrical device is higher than the energy consumption of the electrical device, the electrical module interface 101 is configured as a full-duplex communication interface, and may be specifically configured as at least one of the following: a UART port, an SPI port, an I2C interface, a QSPI interface, and the like.
[0028] In some embodiments, the central processing unit 102 of the integrated circuit 100 is configured to be electrically connected to the electrical module interface 101 and the wireless signal processing unit 103, and is used to process the data received from the electrical module interface 101 and / or the wireless signal processing unit 103, and send the processed data to the wireless signal processing unit 103 and / or the electrical module interface 101. The central processing unit 102 includes a central processing unit (CPU) for outputting signals based on processing programs and data, a read-only memory (ROM) for storing processing programs or control data, a random access memory (RAM) for temporarily storing data, a timer, etc. The central processing unit 102 and the wireless signal processing unit 103 can share the CPU. In some embodiments, the wireless signal processing unit 103 can include a CPU, and the central processing unit 102 and the wireless signal processing unit 103 can share the CPU.
[0029] If the electrical device is an electric tool as an example, the data received by the integrated circuit 100 from the electrical module interface 101 include but are not limited to the start / stop signal of the electric tool, the speed signal of the drive motor, the overload signal of the drive motor, the temperature signal of the electric tool, etc. After the integrated circuit 100 converts and calculates these data, it obtains the processed data and sends it to the wireless signal processing unit 103.

The processed data includes but is not limited to the charge / discharge state indication value, the current battery voltage value, the battery temperature value, the normal state / alarm state indication value of the battery, etc. In some embodiments, the electrical module interface 101 is configured as a full-duplex communication interface, so the central processing unit 102 receives data from the electrical module interface 101, processes it, and then sends it to the wireless signal processing unit 103, and the central processing unit 102 receives data from the wireless signal processing unit 103, processes it, and then sends it to the electrical module interface 101. Data transmission in two directions can be carried out simultaneously, thereby improving the real-time performance of data interaction between the electrical device and external devices.
[0030] In some embodiments, the wireless signal processing unit 103 of the integrated circuit 100 is configured to be connected to the external device 120 by wireless communication, so as to facilitate data interaction with the external device 120. As electrical equipment becomes more and more intelligent, people have higher and higher demands for real-time, remote and convenient control and monitoring of the working conditions of electrical equipment. Therefore, more and more electrical equipment are designed to have wireless communication modules, so that the electrical equipment can perform wireless data interaction with external devices 120 such as mobile phones, watches, tablets, computers and other portable terminals. The effect brought by this is: on the one hand, the user can send control signals and setting parameters to the electrical equipment in real time anytime and anywhere, and on the other hand, the user can also receive the status parameters of the electrical equipment in real time, so as to understand the working status of the electrical equipment in real time for better monitoring. In the prior art, due to the limitations of wafer processing technology, or the requirements of modular design and modular processing of components, the wireless communication module is usually an independent module, which is arranged outside the central processor on the control board of the electrical equipment, so as to perform wired data interaction with the central processor and / or wireless data interaction with external devices. The present invention adopts a completely different solution, integrating the wireless communication function into the central processing unit. Compared with the traditional solution in which the central processing unit module and the wireless communication module are respectively arranged in the electrical equipment control board, the present invention can reduce the area of the electrical equipment control board while realizing wireless communication between the electrical equipment and the external equipment, thereby reducing the volume of the electrical equipment.
[0031] When a traditional Bluetooth module exchanges data with an external device, it receives and sends wireless signals through a Bluetooth antenna. In some embodiments, further considering the anti-interference requirements of wireless signals during transmission, the utility model integrates the wireless signal processing unit 103 in the wireless communication function into the central processing unit, but does not integrate the antenna in the wireless communication function into the central processing unit. In this way, while reducing the area of the control board of the electrical equipment and thus reducing the volume of the electrical equipment, it can also minimize the impact on the transmission of wireless signals, thereby maintaining good signal transmission reliability, and thus users can better control and monitor the working status of the electrical equipment.
[0032] In some embodiments, the wireless signal processing unit 103 can be configured according to the distance between the electrical device and the external device 120, i.e., the wireless signal transmission distance, and the wireless signal transmission rate required by the electrical device in the working state. Exemplarily, the wireless signal processing unit 103 is configured as at least one of the following: a Bluetooth signal processing unit, a WIFI signal processing unit, and a NB-IoT signal processing unit.
[0033] like Figure 2The schematic block diagram of an integrated circuit for electrical equipment according to another embodiment of the utility model is shown. In this embodiment, the integrated circuit 100 further includes a power management unit 104, which is used to simultaneously provide power to the central processing unit 102 and the wireless signal processing unit 103, and simultaneously meet the power supply requirements of the central processing unit 102 and the wireless signal processing unit 103. Therefore, compared with the traditional solution in which the central processing unit module and the wireless communication module are respectively arranged on the control board of the electrical equipment, and thus it is necessary to design power supply lines for the central processing unit module and the wireless communication module respectively, the present solution only needs to design a power supply line for the integrated circuit 100, and can simultaneously provide power to the central processing unit 102 and the wireless signal processing unit 103, further reducing the area of the control board of the electrical equipment, and reducing the difficulty of R&D design and the product debugging cycle, thereby further reducing the R&D cost and the production cost.
[0034] Figure 3 FIG. 1 is a schematic block diagram of an electrical device 10 according to an embodiment of the present utility model. The electrical device 10 includes Figure 1 or Figure 2 The integrated circuit 100 of the embodiment in the embodiment, the electrical module 110 disposed outside the integrated circuit 100, and the antenna unit 105 disposed outside the integrated circuit 100. The electrical module 110 is electrically connected to the integrated circuit 100 to send the state parameters related to the electrical device 10 to the integrated circuit 100, and / or receive the setting parameters related to the electrical device 10 from the integrated circuit 100.
[0035] In some embodiments, the antenna unit 105 is electrically connected to the wireless signal processing unit 103 in the integrated circuit 100, and is used to convert the signal interacting with the wireless signal processing unit 103 into an electromagnetic wave in free space, or convert the electromagnetic wave in free space into a signal that can interact with the wireless signal processing unit 103. In one embodiment, the integrated circuit 100 uses a FR306x series chip with a Bluetooth signal processing function, and the antenna unit 105 is configured as an on-chip Bluetooth antenna that matches the Bluetooth frequency band of the FR306x series chip, and is used to convert the high-frequency current signal received from the Bluetooth signal pin of the FR306x series chip into an electromagnetic wave in free space and then send it to the external device 120, and / or convert the electromagnetic wave in free space received from the external device 120 into a high-frequency current signal and then send it to the Bluetooth signal pin of the FR306x series chip. In this embodiment, the FR306x series integrated circuit 100 with a Bluetooth signal processing unit is used as the main chip to cooperate with the on-chip Bluetooth antenna 105 for data transmission, and there is no need to configure a Bluetooth module separately, which reduces the area of the control board of the electrical equipment, and at the same time reduces the R&D design and production costs of the control board. Through the cooperation of the Bluetooth signal processing unit inside the FR306x series chip and the on-chip antenna 105, the utility model realizes the Bluetooth connection between the electrical device 10 and the external device 120, i.e., the user terminal. On the one hand, it can receive the data sent by the user terminal in real time, and on the other hand, it can upload the working status of the electrical device to the user terminal in real time, so that the user can not only remotely start / stop and adjust the operation of the electrical device, but also monitor and analyze the use of the electrical device in real time through the user terminal APP. In other embodiments, the present disclosure is also applicable to application scenarios in which the Internet of Things has multiple electrical devices 10 that need to be connected to the external device 120. The wireless signal processing unit 103 can also be an NB-IoT signal processing unit. At this time, multiple electrical devices 10 are directly deployed on the LTE network and connected to the cellular data of the wide area network. Through a user terminal 120, the operation of multiple electrical devices 10 can be set and monitored at the same time, thereby greatly improving the user experience.
[0036] The electrical device may be, for example, a battery device, a charging device, an electric tool, etc. Figure 41 is a schematic block diagram of an electrical device according to another embodiment of the present utility model. This embodiment is described by taking the electrical device 10 configured as a battery device 10 as an example. The present utility model is not intended to limit the battery type, for example, it can be any type such as a lithium-ion battery, a lithium battery, a nickel-hydrogen battery, etc. The battery device 10 is used to electrically connect with a charging device to obtain and store electrical energy, or to electrically connect with an electrical device to release or provide electrical energy. The electrical module 110 located outside the FR306x series chip includes a charge and discharge control unit 112, a signal acquisition unit 113, and a display unit 114. The charge and discharge control unit 112 is configured to be electrically connected to the FR306x series chip. When the battery device 10 is electrically connected to the charging device, the charge and discharge control unit 112 controls the battery device 10 to obtain and store electrical energy from the charging device according to a predetermined mode; when the battery device 10 is electrically connected to the electrical device, the charge and discharge control unit 112 controls the battery device 10 to release or provide electrical energy to the electrical device according to a predetermined mode.
[0037] The signal acquisition unit 113 is also electrically connected to the FR306x series chip. When the battery device 10 obtains electric energy from the charging device or provides electric energy to the power-consuming device, the signal acquisition unit 113 collects state parameters related to the battery device 10 and sends the state parameters to the FR306x series chip, exemplarily to the electrical module interface 101. The state parameters include, but are not limited to, parameters related to the current state of the battery device 10, such as temperature value, current voltage value (single cell voltage or battery pack voltage), power output capacity or allowable input range, etc., or state parameters related to the charging or discharging process of the battery device 10, such as charging and discharging voltage / current value, communication state value, etc. For example, the signal acquisition unit 113 detects state parameter information related to the charging device providing electric energy to the battery device 10 or the power-consuming device obtaining electric energy from the battery device 10, and sends the detected state parameter information to the electrical module interface 101. The display unit 114 is also electrically connected to the FR306x series chip. When the display unit 114 receives data from the FR306x series chip, the display unit 114 displays the received data so that the user can monitor the charging / discharging status of the battery device 10 in real time.
[0038] On the one hand, the FR306x series chip sends the parameters to be displayed to the display unit 114, and on the other hand, sends the parameters to be presented to the external device 120 to the on-chip Bluetooth antenna 105 through the Bluetooth signal pin of the chip. The on-chip Bluetooth antenna 105 converts the high-frequency current signal received from the Bluetooth signal pin into an electromagnetic wave in free space and sends it to the external device 120. At the same time, the external device 120 can convert the charge and discharge control instructions for the battery device 10 into high-frequency current signals through the on-chip Bluetooth antenna 105 and send them to the Bluetooth signal pin of the FR306x series chip, thereby performing real-time control of the battery device 10. The battery device 10 disclosed in the present invention adopts an integrated circuit 100 with a Bluetooth signal processing unit 103 as the main control chip, and cooperates with the antenna unit 105 for data transmission. There is no need to configure a Bluetooth module separately, which reduces the area of the electrical device control board, thereby reducing the volume of the electrical device; at the same time, due to the reduction in the number of components, the overall circuit design is simplified, and the research and development design cost and production cost of the electrical device control board are also reduced. In addition, since a separate Bluetooth module is omitted, the solution disclosed in the present invention does not need to provide power to the Bluetooth module separately, thereby reducing the energy consumption of the electrical equipment control board, thereby reducing the energy consumption of the entire electrical equipment, improving the battery durability of the entire electrical equipment, and further improving the user experience.

The electrical module 210 includes a switch unit 211, a charging control unit 212, a signal acquisition unit 213, and a display unit 214. The switch unit 211 is electrically connected to the integrated circuit 100. When the charging device 20 is electrically connected to the battery device 10, the charging device 20 can be started or stopped to provide electrical energy to the battery device 10 through the switch unit 211. The charging control unit 212 is also electrically connected to the integrated circuit 100, and is used to control the charging device 20 to provide electrical energy to the battery device 10 according to a predetermined charging mode, and can adjust the mode of the charging device 20 providing electrical energy to the battery device 10 according to the current state of the battery device 10 collected by the signal acquisition unit 213, such as pre-charging, fast charging, trickle charging, etc. The signal acquisition unit 213 is electrically connected to the integrated circuit 100. When the charging device 20 provides power to the battery device 10, the signal acquisition unit 213 collects working state parameters related to the charging device 20 and / or the battery device 10 electrically connected to the charging device 20, and sends the collected state parameters to the integrated circuit 100 through the electrical module interface 101. The state parameters include but are not limited to the mode of providing power, the state of the power grid, the current state of the battery device 10 electrically connected to the charging device 20, etc. The display unit 214 is also electrically connected to the integrated circuit 100, and is used to receive data from the integrated circuit 100 and display the data so that the user can monitor the charging state of the charging device 20 in real time.
[0040] On the one hand, the integrated circuit 100 sends the parameters to be displayed to the display unit 214, and on the other hand, sends the parameters to be presented to the external device 120 to the antenna unit 105 through the wireless signal processing unit 103. The antenna unit 105 converts the received high-frequency current signal into an electromagnetic wave in free space and sends it to the external device 120. At the same time, the external device 120 can convert the charging control instruction for the charging device 20 into a high-frequency current signal through the antenna unit 105 and send it to the wireless signal processing unit 103, so as to perform real-time control of the charging device 20. The charging device 20 disclosed in the present invention adopts the integrated circuit 100 with the wireless signal processing unit 103 as the main control chip, and cooperates with the antenna unit 105 for data transmission, which reduces the area of the control board of the electrical device, thereby reducing the volume of the electrical device; at the same time, it simplifies the overall circuit design, and also reduces the research and development design cost and production cost of the control board of the electrical device. In addition, the energy consumption of the control board of the electrical device is reduced, thereby reducing the energy consumption of the entire electrical device and improving the battery durability of the entire electrical device.

The switch unit 311 is electrically connected to the integrated circuit 100. When the electric tool 30 is electrically connected to the battery device 10, the switch unit 311 can start or stop the electric tool 30 from driving the power unit to rotate. The signal acquisition unit 313 is electrically connected to the integrated circuit 100. When the power unit of the electric tool 30 rotates, the signal acquisition unit 313 collects state parameters related to the electric tool 30 and sends the state parameters to the integrated circuit 100 through the electrical module interface 101. The state parameters include but are not limited to the rotation speed of the power unit, the rotation position detection signal of the power unit, the power supply to the power unit, and the overcurrent, high temperature, or undervoltage of the battery device 10 caused by the excessive load of the power unit.
