Member is connect by network interface with computer client, realizes the register of user.In serial ports switch unit, three road main frames
It exports serial ports and connects three different serial equipments, the serial ports switching command received by I2C buses, each serial equipment can
Any one host of three computers is distributed in timesharing.
According to currently preferred, the ARM controlling unit is to be provided with the embedded-type ARM chip of network interface；It is and embedding
Enter under formula operating system with WEB server, realize the Telnet management to UART serial control systems.
It is further preferred that the embedded OS is the (SuSE) Linux OS with WEB server.
A kind of method of work of above-mentioned UART serial control systems is as follows including step：
1) start the operating system of ARM controlling unit, user logs in serial interface management interface；
2) user formulates serial ports allocation strategy by serial interface management interface and serial ports allocation strategy is issued to ARM control lists
Member；
3) ARM controlling unit sends out serial ports distribution order according to the serial ports allocation strategy；ARM controlling unit divides serial ports
Serial ports switch unit is transmitted to order；
4) serial ports switch unit distributes order according to serial ports and carries out serial ports batch operation；And serial ports distribution state is passed back to
