Counting and measuring the bookmark0 your paper gets the relevant entrepreneurs' evaluation book1 Chen Hongwei Li Yan Yu Mengzhen PC. The software design of the controller adopts a modular method. The startup control process of different models is written into different sub-modules. The combination of different modules is determined by the setting parameters of the E2PROM in the CPU.
The communication management machine is designed as a hardware block diagram of the communication management machine. In the figure, the M68HC11E9 is working in an extended mode. See Resources and Usage. The design expands a random access memory (RAM6264 for storing data; expands a universal asynchronous serial receiver/transmitter (UART8250 for generating a standard RS-232 serial interface, which can be connected to the MODEMCPU) The standard NRZ serial interface generates the RS-485 interface through the MAX491 chip, and acts as the host of the controller, and uses the address wake-up method to form a master-slave multi-machine communication with the controller. The software of the communication machine is written in assembly language and solidified in the CPU. In the program memory, once power is turned on, the program starts running the program from the start address D000H.
The monitoring screen is written in Visual C++ 6.0, and the main screen is as shown. It includes panel buttons, diesel engine running status display, alarm information display, speed display, working condition indication, serial port selection and other parts. After the correct connection, select the serial port and click the communication button with the mouse. If the communication is normal, the content communication in the frame stops to become normal communication, and the three buttons of dialing, communication and parameter setting are blocked, and the monitoring screen correctly reflects the information. In the case of remote control permission, the remote command can be operated; if the communication is not normal, the content in the communication stop box becomes a communication error, and the three buttons of dialing, communication, and parameter setting are blocked, and the information on the screen cannot reflect the status of the controller. The remote command is invalid; if you need to try again, click the hang up button to click the communication button again. The setup includes two aspects: the initialization settings of the modem; and the parameter settings for making the controller universal.
The settings for modifying the operating parameters of the controller through the PC include: diesel engine model selection, switch input definition, switch output definition, speed setting, and starting motor setting.

The controller and communication management machine take Motorola microcontroller as the core to complete the tasks of measurement and control, information collection and command distribution; The host computer takes the PC as the core, and realizes remote remote control and telemetry by connecting the MODEM and using the telephone line.
The actual use shows that the system works reliably, the performance is stable, the operation is convenient, and the user is affirmed.
