Description

Technical Field

[0002] Kerosene cleaning is a cleaning method that uses kerosene (also known as kerosene or light oil) as a cleaning agent. Kerosene has strong dissolving and penetrating abilities and can effectively dissolve and remove grease, dirt and rust from the bearing surface. Kerosene can thoroughly clean the dirt on the bearing surface through steps such as soaking, brushing and rinsing. It can effectively remove dirt and restore the bearing to a clean state.

[0032] According to another embodiment of the present invention, further comprising: Fig.10 As shown, the microcontroller uses the chip STM32F407ZET6, wherein pins PA0 and PA1 are connected to the ultrasonic rangefinder 21, PA0 is used as the ultrasonic return input capture pin function, and PA1 is used as a general output pin function; pin PA2 is connected to the drying fan 30, pin PA3 is connected to the drying solenoid valve 33, and pin PA4 is connected to the fan; pins PA5, PA6, and PA7 are used as SPI function pins to connect the temperature, humidity, and air pressure sensors of the environmental parameter sensor 25, and PB6 is used as the SPI function pins to connect the temperature, humidity, and air pressure sensors of the environmental parameter sensor 25. As a general output pin function, it is connected to the chip select signal of the environmental parameter sensor; pins PA13, PA14, PA15, PB3, and PB4 are connected to the program firmware download port; pins PB0 and PB1 are connected to the weighing sensor 23, and pin PE4 is used as an external interrupt pin to pull up and enable the peeling function of the weighing sensor 23; pins PB8 and PB9 are connected to the proximity sensor 22, and pin PE2 is used as an external interrupt pin to connect the proximity interrupt trigger pin of the proximity sensor 22; pins PB10 and PB11 are connected to the AT command interface of the NB-IOT module, and PF8 is used as a general output function pin to connect the reset pin of the NB-IOT module; pins PB13, PB14, and PB15 are used as SPI functions to connect the timing unit, and pin PD8 is used as The general output pin function connects the timing unit clock chip pin; pins PC1, PC3, PE3, PE5 are connected to the acceleration sensor 24, pins PC4, PC5, PC6 are connected to the stepper motor 7, pins PD9 to PD13 are connected to the display module one, PD11, PD12, PD13 are general output pins connected to the reset pin, data command pin and chip select pin of the display module one respectively; pins PD5, PG12 to PG15 are connected to the display module two, PG15 is a general output pin connected to the reset pin of the display module two; pins PE7 and pin PE8 are connected to the digital tube display module for displaying countdown; pins PE10 to PM15 and PF9 are used as the PWM output channel of the timer to connect to the servo 13 to provide PWM signals.

[0033] Specifically, the microcontroller uses the STM32F407ZET6 chip (hereinafter referred to as STM32), which supports the DSP instruction set, has 1MB of FLASH memory, 192KB of SRAM memory, and provides a wealth of peripheral interfaces, including multi-channel ADC conversion and 12 16-bit timers with PWM output, 2 32-bit timers, 6 USART / UART interfaces, etc. On the basis of completing the hardware physical layer design, according to system needs, through the software framework structure such as Fig. 9 As shown in the figure, the codes of each functional module are programmed. The software system design is mainly carried out at two application levels: the STM32 side and the Alibaba Cloud IoT platform side. The application layer software design of the STM32 side as an IoT node is mainly to drive various hardware modules, collect relevant sensor data, send NB-IoT commands, etc.; the application layer software design of the Alibaba Cloud IoT platform side mainly includes the definition of cloud devices, products, functions, etc., as well as the development and design of IoT Studio, etc. The two application layers communicate through the MQTT protocol. The STM32 side first initializes each functional module and sets relevant parameters to ensure that it can work normally as required, and then enters the real-time data parameter monitoring stage. Each module cooperates with the main program to complete the monitoring trigger and data reporting. The STM32 sends and receives data with the NB-IOT module through the serial port, and operates the NB-IOT module by sending AT commands. The grammatical structure of the AT command is: any command starts with "AT" or "at" and ends with <cr>End command input. After sending an AT command, the returned response is usually <cr> <lf> <response> <cr> <lf>,in <cr>Indicates a carriage return character, represented by "\r\n". <lf>Indicates a line break. The types of AT commands issued and responded to are shown in Table 1. Alibaba Cloud IoT platform provides secure and reliable device connection and communication capabilities, supports device data collection on the cloud, rule engine data flow, and cloud data delivery to the device, and supports object model definition, data structured storage, and remote debugging, monitoring, and operation and maintenance. The NB-IoT workflow is as follows: (1) Set the RST pin of the NB-IoT module high and then pull it low to achieve hardware reset; (2) Send the "AT+QRST=1" command to reset the NB-IoT module software; (3) Send the "AT+QMTDISC=0" command to disconnect the device node from the Alibaba Cloud IoT platform server. This command is added mainly to prevent the device from restarting due to some reasons after running for a period of time, and the Keeplive time has not expired. The Alibaba Cloud IoT platform believes that the device node is still online, so the command is executed and the node actively disconnects first. (4) Send the "AT+QMTCLOSE=0" command to close the MQTT network on the device node side. The reason for adding this command is the same as step 3. (5) Send the "AT" command. If it returns OK, it means the BC20 module of the NB-IOT module is working properly. If it returns ERROR, restart the system. (6) Send the "AT+CFUN=1" command to set BC20 to run in full-function mode; (7) Send the "AT+CIMI" command to obtain the unique international mobile subscriber identification code of the SIM card. This identification code is used as the login name for logging into the Alibaba Cloud IoT platform through MQTT to ensure the uniqueness of the node login identifier; (8) Send the "AT+CGATT=1" command to attach to the PS (Packet Switch) domain packet switching network and activate all PDP (Packet Data Protocol) packet message protocol contexts; (9) Send the "AT+CGATT?" command to query the current PS domain service status. If "+CGATT:1" is returned, it means that the network is successfully attached. (10) Send the "AT+CESQ" command to query the network signal quality. If the signal quality is too low, the system will output relevant prompt information and restart the system.
