[0070] In some embodiments of the present application, when the message to be converted is a CAN message and the target message is an Ethernet message, step S200 is further described. The step S200 of "converting the message to be converted into the target message" includes:

[0071] Step S210: Obtain a first mapping table, the first mapping table including a plurality of first mapping relationships, the first mapping relationship being a mapping relationship between an ID address and an IP address;

[0073] Step S212: Obtain the target IP address according to the ID address and the first mapping table;

[0075] In this embodiment, after receiving a CAN message, the CAN bus module parses the CAN message to obtain the ID address and CAN data. Based on the ID address, the module queries the first mapping table to obtain the target IP address. The CAN message and target IP address are then encapsulated into a UDP message, i.e., an Ethernet message, which is then transmitted via the Ethernet module.

[0076] In some embodiments of the present application, when the message to be converted is an Ethernet message and the target message is a CAN message, step S200 is further described. The step S200 of "converting the message to be converted into the target message" includes:

[0079] In this embodiment, after receiving the Ethernet message, that is, the UDP message, the Ethernet module parses the UDP message to obtain the ID address and CAN data, encapsulates the ID address and CAN data to obtain a CAN message, and then sends it to the CAN bus module.

[0080] In some embodiments of the present application, when the message to be converted is a serial port message and the target message is an Ethernet message, step S200 is further described. The step S200 of "converting the message to be converted into the target message" includes:

[0081] Step S231: remove the check code of the serial port message to obtain the intermediate message;

[0082] Step S232: Add an Ethernet message header to the intermediate message to obtain an Ethernet message.

[0083] In this embodiment, after receiving an RTU message (i.e., a serial message), the serial port module removes the CRC checksum from the serial message to obtain an intermediate message. An Ethernet message header (i.e., a TCP header) is added to the intermediate message to obtain a TCP message (i.e., an Ethernet message). The Ethernet module then transmits the Ethernet message.

[0084] In some embodiments of the present application, when the message to be converted is an Ethernet message and the target message is a serial port message, step S200 is further described. The step S200 of "converting the message to be converted into the target message" includes:

[0085] Step S241: Parse the Ethernet message to obtain Ethernet data;

[0086] Step S242: Add a check code to the Ethernet data to obtain a serial port message.

[0087] In this embodiment, after receiving the Ethernet message, the Ethernet module parses the Ethernet message to obtain Ethernet data, namely PDU data, adds a CRC check code to the PDU data to obtain an RTU message, and then sends the RTU message through the serial port module.

[0088] In some embodiments of the present application, when the message to be converted is a CAN message and the target message is a serial port message, step S200 is further described. The step S200 of "converting the message to be converted into the target message" includes:

[0089] Step S251: obtaining a second mapping table, the second mapping table including a plurality of second mapping relationships, the second mapping relationship being a mapping relationship between an ID address and a register address;

[0090] Step S252: Parse the CAN message to obtain the target ID address and CAN data;

[0091] Step S253: Obtain the target register address according to the target ID address and the second mapping table;

[0093] In this embodiment, after receiving a CAN message, the CAN bus module parses the CAN message to obtain a target ID address and CAN data, queries a second mapping table based on the target ID address, obtains a target register address, encapsulates the target register address and CAN data, obtains a serial message, and then sends the serial message through the serial port module.

[0094] In some embodiments of the present application, when the message to be converted is a serial port message and the target message is a CAN message, step S200 is further described. The step S200 of "converting the message to be converted into the target message" includes:

[0095] Step S261: obtaining a second mapping table, the second mapping table including a plurality of second mapping relationships, the second mapping relationship being a mapping relationship between an ID address and a register address;

[0096] Step S262: Parse the serial port message to obtain the serial port data and the target register address;

[0097] Step S263: Obtain the target ID address according to the target register address and the second mapping table;

[0098] Step S264: Encapsulate the serial port data and the target ID address to obtain a CAN message.

[0099] In this embodiment, after receiving a serial message, the serial port module parses the serial message to obtain the serial data and the target register address. Based on the target register address and the second mapping table, the target ID address is obtained. The serial data and the target ID address are encapsulated to obtain a CAN message, which is then sent via the CAN bus module.

[0100] In some embodiments of the present application, a dedicated hardware arbitration module is integrated into the main control chip to detect the data flow of the communication protocol interface of the CAN bus module, Ethernet module, and serial port module in real time and dynamically allocate processing priorities:

[0101] a) Highest priority (real-time control): CAN bus module, response delay less than 1ms;

[0102] b) Second priority (large data transmission): Ethernet module, bandwidth utilization greater than or equal to 90%;

[0103] c) Lowest priority (low-speed device): serial port module, polling interval is configurable.

[0104] In this embodiment, when multiple protocols initiate transmission requests simultaneously, the arbitration module allocates bus usage rights in order of priority; and enables a cache queue for low-priority data.

[0105] In some embodiments of the present application, the method further comprises:

[0106] Step S400: obtaining the battery temperature of the industrial tablet computer;

[0107] Step S410: If the battery temperature is lower than a preset first temperature threshold;

[0108] Step S420: controlling the battery to output a pulse current until the battery temperature rises to a preset second temperature threshold.

[0109] In this embodiment, a battery temperature sensor monitors the battery temperature. If the battery temperature falls below a first temperature threshold, the battery is controlled to output alternating positive and negative high-frequency pulse currents, thereby raising the battery temperature. When the battery temperature rises to a preset second temperature threshold, the battery is controlled to stop outputting the pulse currents.

[0110] In some embodiments of the present application, the frequency of the pulse current is 5 kHz, and to balance the heating rate with the risk of lithium deposition, the current is 0.5 C. The duty cycle of the pulse current is 50%, and the positive and negative pulses are symmetrical to avoid net charge accumulation leading to lithium deposition.

[0111] In some embodiments of the present application, a battery management system reads the battery voltage, internal resistance, and current temperature to assess the battery health status. The battery uses an ultra-low temperature electrolyte formula and a composite negative electrode material.

[0112] In some embodiments of the present application, the “controlling the battery output pulse current” in step S420 is further described. Step S420 includes:

[0113] Step S421: Controlling the battery to output a first pulse current at a preset first discharge rate for a first preset time;

[0114] Step S421: controlling the battery to output a second pulse current at a preset second discharge rate, where the second discharge rate is greater than the first discharge rate.

[0115] In this embodiment, a first pulse current is output at a first discharge rate (e.g., 0.1C) for a first preset time (e.g., 30 seconds), with a frequency of 1kHz. The discharge rate is then gradually increased to a second discharge rate (e.g., 0.5C, 1C), and a second pulse current is output at a frequency of 5kHz. This prevents a sudden increase in internal resistance or local overheating of the battery caused by electrolyte solidification at low temperatures.

[0116] The battery temperature, voltage and internal resistance are collected every 10 seconds. If a sudden voltage drop (indicating the risk of lithium deposition) or a temperature rise rate greater than 5°C / min is detected, the current is reduced to the preset safety threshold.

[0117] The first temperature threshold is not limited to a value; for example, it can be set to -20°C. The second temperature threshold is not limited to a value and can be determined based on the device's operating temperature; for example, it can be set to -20°C. Upon reaching the second temperature threshold, the output pulse current heating stops and the device switches to normal discharge mode. If the heating timeout occurs (for example, if the second temperature threshold is not reached within 10 minutes), a low-temperature alarm is triggered and the output is cut off.

[0118] In some embodiments of the present application, when the pulse current exceeds 1.2C, the output pulse current is immediately terminated and switched to the bypass circuit.

[0119] In some embodiments of the present application, multiple temperature probe detection and temperature equalization design are used to ensure that the temperature difference between battery cells is less than 2°C.

[0120] In some embodiments of the present application, lithium metal is partially dissolved by the reverse phase of the pulse current (ie, negative current), and the dendrite growth is reduced in combination with the LiNO3 additive.

[0121] In some embodiments of the present application, an H-bridge driver circuit generates alternating positive and negative pulse currents to control the current direction and amplitude. The H-bridge driver circuit includes four MOSFETs that achieve bidirectional current drive by alternating diagonal switches. The driver chip receives PWM signals from the main control chip and provides high-side / low-side drive voltages. The pulse current passes through the positive electrode of the battery, the H-bridge driver circuit, the shunt, and the negative electrode of the battery in sequence, forming a closed loop.

[0122] In some embodiments of the present application, the battery temperature sensor is a chip-type NTC thermistor installed on the surface of the battery cell.

[0123] In some embodiments of the present application, a protection circuit module is also included to prevent abnormal conditions such as overvoltage, overcurrent, and temperature gradient exceeding the limit.

[0124] In some embodiments of the present application, during the low-temperature startup phase, when the battery temperature is less than -20°C, power is supplied only to the battery management system, H-bridge driver circuit, battery temperature sensor, and RTC clock. When the temperature is between -20°C and 0°C, the low-power core of the main control chip is activated, the CAN bus module, Ethernet module, and serial port module maintain basic monitoring, the screen remains off, and the ADC acquisition module and discrete input and output modules operate at current limiting. When the temperature is greater than or equal to 0°C, the industrial tablet computer resumes all functions and operates at full capacity.
