CAN module 1CANBUS USER MANUAL 1.1. REQUIREMENTS 1.1.1. PHYSICAL REQUIREMENTS The module shall be compatible with various types of power supply for different commercial vehicles, mainly 12V and 24V. Normal operating conditions： • Operating temperature： -40℃—+85℃； • Relative humidity： 45%—75%； • Pressure： 86Kpa—106Kpa（absolute pressure value）； • Storage temperature range：-40℃—+85℃. 1.1.2. FUNCTION REQUIREMENT CAN module shall be able to receive, process, analyze, store and transmit data from the sensors and the tool. Its main functions are as follows: • Reliable data receiving: the receiving rate shall > 90% • Time setting • Data storage • Serial Port data transmission • Sensor ID registration The module communicates with TPMS Smart Tool and realizes ID LEARNING. After TPMS is started, the CAN module will transmit its ID to TPMS Smart Tool by RF. Then the Sensor ID of each tire will be learned by TPMS Smart Tool. All the Sensors ID and CAN module ID in the TPMS Smart Tool are transmitted to CANBUS again for registration. Besides, the data of pressure and temperature of tires will be transmitted by CANBUS, not by RF. 1.1.3. PROPERTIES REQUIREMENT • Reverse polarity requirements: after one-minute connection of reverse polarity, the product shall be able to function properly with normal power supply; • Receiver’s contact discharge level is 8KV, air discharge level is 15KV. 1.2. CAN MODULE PRINCIPLE CAN module is used to receive wireless information, and appropriately process and display information. Main parts and functions of CAN module are： • R/F receiver module decodes high frequency signal transmitted by tractor’s transmitting module and transceiver module; then it sends the data package to MCU through SPI port. • MCU analyzes data information in the data package. In the case of tire pressure sensor signal, sensor ID will be analyzed. If sensor ID is the same with its predetermined ID information, its temperature and pressure information will be collected and processed; once sensor ID is different with its predetermined ID information, the data will not be considered as that vehicle’s tire data and will not be processed. • Power system will change 12V or 24V vehicle power supply into normal operating voltages for different modules.
CAN module 2• Memory module records tire information stored by the receiver (if any abnormality occurred in any tire, the tire information will be immediately stored), the data can be downloaded to a computer through Serial Port or wirelessly for analysis. 1.3.

CAN module 31.3.3. FUNCTIONS 1.3.3.1. HIGH PRESSURE WARNING When tire pressure is≥10.8Bar（8.3*1.3）, high pressure warning level two, potential risky status, driver shall stop the vehicle and adjust tire pressure immediately. When tire pressure is≥9.5Bar（8.3*1.15）, high pressure warning level one, it calls driver’s attention to tire pressure and adjust tire pressure accordingly. 1.3.3.2. LOW PRESSURE WARNING When tire pressure is < 7.4Bar（8.3*0.9）, low pressure warning level one, it calls driver’s attention to tire pressure and adjust tire pressure accordingly. When tire pressure is< 6.6Bar（8.3*0.8）, low pressure warning level two, potential risky status, driver shall stop the vehicle and adjust tire pressure immediately. 1.3.3.3. HIGH TEMPERATURE WARNING： When tire pressure is≥80℃, it gives out high temperature warning, driver shall stop the vehicle and lower the temperature of the tire. 1.3.3.4. FAST LEAKAGE WARNING： When the tire pressure loss is ≥0.33Bar within 16s, it gives out fast leakage warning, driver shall stop the vehicle and make appropriate treatment. 1.3.3.5. NON-RECEIVING DATA WARNING： When the system does not receive tire pressure information for more than 20 minutes, it gives out non-receiving data warning. 1.3.3.6. CAN BUS COMMUNICATIONS When any of the above 5 kinds of information is received, the system will send data to ICM through CAN BUS for processing. 1.3.3.7. DATA STORAGE The system can store 4300 of tire information. Under normal conditions, data shall be stored every 30 minutes; under abnormal condition, data shall be stored every 10s. When abnormality occurs in any tire, the stored information shall be reviewed. The function is similar to Black Box. 1.3.3.8. ID LEARNING The module communicates with TPMS Smart Tool and realizes ID LEARNING; To make integration of TPMS to vehicles simple, save installation time, our proposed installation process is as follows:
