[0002] At present, traditional energy storage devices are in a dilemma of not being able to access the Internet of Things.

[0035] An energy storage controller Internet of Things platform access device, including an Internet of Things wireless module, a power-on drive module, a user identity recognition module, a storage module, a power management module, a radio frequency module, an interface module, a serial port drive module, a communication module and an LED indicator light module;

[0036] The Internet of Things wireless module is electrically connected to the power-on drive module, the user identity recognition module, the storage module, the power management module, the radio frequency module, the interface module, the serial port drive module, the communication module and the indicator light module respectively.

[0037] The networking wireless module adopts the EC200U module.

[0038] Figure 2 This is the circuit diagram of the power-on driver module;

[0039] When the device block is in shutdown mode, you can power on the device by pulling PWRKEY low for at least 2s. It is recommended to use an open-collector or open-drain driver circuit to control the PWRKEY pin.

[0040] Figure 3 It is the circuit diagram of the user identification module;

[0041] The chip used in the user identity identification module is a uSIM card. The VCC pin of the uSIM card is connected to the GND pin and the USIM_GND of the EC200U module through a 100nF capacitor. The VCC pin, RST pin, CLK pin, and IO pin of the uSIM card are connected to the TVS diode. The RST pin of the uSIM card is connected to the USIM_RST of the EC200U module, and the CLK pin of the uSIM card is connected to the USIM_CLK of the EC200U module.

[0042] The user identification module circuit complies with ETSI and IMT-2000 specifications and supports 1.8V and 3.0V (U)SIM cards. If the (U)SIM card detection function is not required, keep the USIM1_DET pin floating.

[0043] The storage module adopts an SD card storage circuit;

[0044] Figure 4 It is the circuit diagram of the storage module;

[0045] The VDD pin of the SD card storage circuit is connected to one end of capacitor C7, one end of capacitor C8, one end of capacitor C9, one end of capacitor C10, and VDD3.3V respectively; the other end of capacitor C7, the other end of capacitor C8, the other end of capacitor C9, and the other end of capacitor C10 are all connected to the ground, and the CD / DAT3 pin, DAT2 pin, DAT1 pin, DAT0 pin, CLK pin, CMD pin, and DETECTIVE pin of the SD card storage circuit are respectively connected to the SDIO1_DAT0 of the EC200U module. The A3 pin, the SDIO1_DATA2 pin, the SDIO1_DATA1 pin, the SDIO1_DATA0 pin, the SDIO1_CLK pin, the SDIO1_CMD pin, and the SD_DET pin are connected, and the SDIO_VDD pin of the EC200U module is connected to the cathode of the diode D1, the cathode of the diode D2, the cathode of the diode D3, the cathode of the diode D4, and the cathode of the diode D5 through resistors R7, R8, R9, R10, and R11, respectively.

[0046] The function of the SD card memory circuit is to connect the SD card to the EC200U module to realize data reading and writing operations. The SD card memory circuit provides a stable connection for reliable data transmission between the SD card and the EC200U module. The voltage range of the SD card power supply VDD3V3 is 2.7~3.6V, and at least 800mA current must be provided. The maximum output current of the module output power supply SDIO_VDD is 150mA, which can only be used for SDIO bus pull-up. In order to avoid bus jitter, it is necessary to reserve pull-up resistors R7~R11 for the SDIO signal, and the recommended value is 4.7kΩ. The pull-up power supply must select the module's SDIO_VDD. In order to adjust the signal quality, it is necessary to reserve SDIO signal series resistors R1~R5, with a recommended value of 0Ω and a recommended value of 33Ω for R6; reserve capacitors C1~C6, which are not mounted by default. When placing PCB ornaments, resistors and capacitors need to be placed close to the module side. To ensure good ESD performance, it is recommended to add a TVS tube to the SD card pin and place it as close to the SD card holder as possible, and ensure that the junction capacitance of the TVS tube is less than 15pF. The SD card power supply needs to be provided from outside the module.

[0047] Figure 5 It is the circuit diagram of the power management module;

[0048] The power supply range of the power management is 3.3-4.3 V, and it is necessary to ensure that the input voltage is not lower than 3.3 V. To ensure the stability of the power supply, a TVS tube is added to the front end of the power supply.

[0050] The interface module uses a USB interface. The USB interface of the module complies with the USB2.0 specification and supports full-speed (12Mbps) and high-speed (480Mbps) modes. The module only supports USB slave mode. This interface can be used for data transmission, software debugging and firmware upgrades. Resistors R1 and R2 are connected in series to the test point for debugging, and the resistors are not attached by default. In order to meet the signal integrity requirements of the USB data line, L1, R1, and R2 need to be placed close to the module, and resistors R1 and R2 must be placed close to each other, and the stub lines connecting the test points should be shortened as much as possible. Special attention should be paid to the selection of ESD protection devices on the USB data line. The parasitic capacitance should not exceed 2pF, and it should be placed as close to the USB connector as possible.

[0051] Figure 7 This is the circuit diagram of the LED indicator module;

[0052] The LED indicator module is mainly used to drive external network indicator lights. The module provides two network status indication pins, NET_MODE and NET_STATUS, to indicate the logic level changes under different network states.

[0053] Among them, NET_MODE status:

[0054] High level: indicates registration to LTE network status;

[0055] Low level: indicates other;

[0056] Among them: NET_STATUS status:

[0057] Slow flashing (200ms high / 1800ms low) indicates network registration failure and network search status.

[0058] Fast flashing (234ms high / 266ms low) indicates successful network injection and standby status.

[0059] Fast flash (63ms low / 62ms high indicates data transmission mode

[0060] A high level indicates a call in progress;

The main functions include transmitting data and instructions, controlling external devices, monitoring and debugging systems, program downloading and updating, and recording debugging information. It provides engineers with a convenient and reliable communication channel, which helps to efficiently debug and develop embedded systems
