[0031] Specifically, this technical solution provides a tricycle controller that includes the following modules and devices: a motor drive module, a communication module, a data processing module, a heat dissipation module, a data storage module, a data acquisition module, a power supply module, and an alarm device. Through rational connection design between these modules and devices, efficient data transmission and control functions are achieved.

[0032] The motor drive module is the core of the tricycle controller and primarily includes the motor driver, motor status data acquisition device, and data storage. The motor driver utilizes a high-performance IGBT (insulated gate bipolar transistor) driver chip, such as Infineon's AUIR3310S. This chip features high switching frequency and low losses, effectively improving the motor's response speed and efficiency.

[0033] The motor status data acquisition device includes a speed sensor, a motor temperature sensor, a motor noise sensor, and an analog-to-digital converter. The speed sensor uses a Hall-effect sensor, such as Honeywell's HMC1501, to accurately measure motor speed. The motor temperature sensor uses an NTC thermistor, such as Murata's NCP15XH103F03RC, to monitor motor temperature in real time. The motor noise sensor uses a microphone, such as the Knowles SPU0410LR5H-QB, which offers a high signal-to-noise ratio, to detect motor operating noise. The analog-to-digital converter uses a high-precision ADC chip, such as Texas Instruments' ADS127L01, to convert the analog signals collected by the sensors into digital signals for transmission to the data processing module.

[0034] The data memory uses a serial Flash memory, such as Spansion's S25FL256S, to store the motor's historical operating data and configuration parameters, facilitating subsequent data analysis and debugging.

[0035] The communication module is responsible for communicating between the tricycle controller and external devices, and includes a wireless communication module and a data interface. The wireless communication module uses a Bluetooth module, specifically the CSR8670. This module supports the Bluetooth 4.2 standard and features low power consumption and high transmission rates, making it suitable for wireless connections between the tricycle controller and devices such as smartphones and tablets.

[0036] The data interface includes a USB interface, which uses a standard USB Type-C interface. The specific model is Texas Instruments' TPS65982, which supports the USB 3.1 standard and can provide high-speed data transmission and charging functions, making it convenient for users to perform data backup, firmware upgrades and debugging operations.

[0037] The data processing module is the core processing unit of the tricycle controller and uses a high-performance microcontroller, such as the STMicroelectronics STM32F407VGT6. Based on the ARM Cortex-M4 core, this microcontroller boasts high-speed computing power and a rich set of peripheral interfaces. It efficiently processes data from various modules and performs control and regulation according to pre-set algorithms.

[0038] The heat dissipation module is used to ensure the stability of the tricycle controller under high load operation. It mainly includes a cooling fan, a fan controller, and a fan status detection module. The cooling fan uses a DC brushless fan, such as Sunon's KDE1205PFS1, which has the characteristics of low noise and high air volume.

[0039] The fan controller uses a PWM controller, such as the Texas Instruments LM3501, which adjusts the fan speed according to instructions from the data processing module, achieving intelligent cooling. The fan status detection module includes a fan speed sensor, which uses a Hall effect sensor, such as the Allegro A1321, to monitor the fan speed in real time and feed the data back to the data processing module.

[0040] The data storage module uses a large-capacity SD card memory, such as SanDisk's Ultra microSDXC UHS-I card with a capacity of 64GB, to store the tricycle controller's log files, configuration parameters, and fault records, making it easier for users to perform data analysis and troubleshooting.

[0041] The data acquisition module collects data about the tricycle's operating environment and status. It includes a proximity sensor, an accelerometer, a temperature and humidity sensor, and an analog-to-digital converter. The proximity sensor uses an infrared sensor, such as Sharp's GP2Y0A21YK0F, to detect obstacles around the tricycle. The accelerometer uses a three-axis accelerometer, such as Freescale's MMA8451Q, to measure the tricycle's acceleration and tilt angle. The temperature and humidity sensor uses a digital sensor, such as Sensirion's SHT21, to monitor the ambient temperature and humidity in real time.

[0042] The analog-to-digital converter 2 uses a high-precision ADC chip, such as the AD7920 from Analog Devices, to convert the analog signal collected by the sensor into a digital signal and transmit it to the data processing module.

[0043] The power module is responsible for providing a stable power supply for the tricycle controller. It uses a DC-DC converter, such as the TPS5430DDA from Texas Instruments. This converter has the characteristics of high efficiency and low ripple, and can convert the input DC voltage into the operating voltage required by the controller.

[0044] The alarm device, a combination of a buzzer and LED indicator, alerts the user when the tricycle controller detects an abnormal condition. The buzzer uses a high-decibel model, such as the CUIDevices CEM-1203, which emits a loud alarm sound. The LED indicator uses a high-brightness LED, such as the Osram LWQ6WP-G1U1-1A, which flashes when the controller detects a fault, alerting the user.

[0045] In this embodiment, the tricycle controller is applied to an electric three-wheeled freight vehicle, which needs to frequently travel in complex environments and has high requirements for the stability and intelligence of the controller.

The motor status data acquisition device includes a Hall-effect speed sensor HMC1501, an NTC thermistor NCP15XH103F03RC, and a microphone sensor SPU0410LR5H-QB, monitoring the motor's speed, temperature, and noise in real time. An analog-to-digital converter (ADS127L01) converts the collected analog signals into digital signals for transmission to the data processing module.

[0047] The wireless communication module uses a CSR8670 Bluetooth module to connect to the user's smartphone for remote monitoring and control. The data interface uses a USB Type-C interface TPS65982, which facilitates data backup and firmware upgrades.

[0048] The data processing module uses the STM32F407VGT6 microcontroller to process data from various modules in real time and perform motor control and regulation according to preset algorithms.

[0049] The cooling fan uses Sunon's KDE1205PFS1, the fan controller uses the LM3501 PWM controller, and the fan speed sensor uses Allegro's A1321, which achieves intelligent heat dissipation and ensures the stability of the controller under high load operation.

[0050] The data storage module uses SanDisk's Ultra microSDXC UHS-I card with a capacity of 64GB to store the controller's log files, configuration parameters, and fault records.

[0051] The data acquisition module includes a Sharp GP2Y0A21YK0F proximity sensor, a Freescale MMA8451Q acceleration sensor, and a Sensirion SHT21 temperature and humidity sensor to monitor the tricycle's operating environment and status in real time. The second analog-to-digital converter, an AD7920, converts the collected analog signals into digital signals.

[0052] The power module uses the Texas Instruments TPS5430DDA DC-DC converter to provide a stable operating voltage for the controller.

[0053] The alarm device uses CUIDevices' CEM-1203 buzzer and Osram's LW Q6WP-G1U1-1A LED indicator to alert the user when the controller detects an abnormal state.
