The transmission that Multi-serial port medical treatment gateway makes the serial data in medical detecting Instrument flow to ethernet data stream becomes possibility.This Multi-serial port medical data can connect multiple medical detecting Instrument with RS232 serial ports, and serial data is carried out selecting and processing, the stream compression of RS232 interface is changed into ethernet data stream, so just can carry out the data processing of networking, realize the networking of serial data.
In specific implementation process, its ICP/IP protocol is made up of application layer, UDP layer, IP layer and data link layer.In order to realize transparent transmission in the invention process, increase application process protocol layer---serial ports layer.Serial ports layer is made up of serial ports link layer and serial network layer.Multi-serial port medical treatment gateway, at serial ports layer building, resolves RS232 packet simultaneously, and as the transfer of data of TCP/IP network application layer.Multi-serial port gateway is received and dispatched control module by ICP/IP protocol modular converter and Multi-serial port and is formed, and hardware concrete structure as shown in Figure 4.Protocol conversion module is a miniature Ethernet access module, is made up of microcontroller (MCU), network card interface chip, EEPROM 93C46, the outer 512KBSRAM chip I S6lLV5128 of sheet and auxiliary element.Microprocessor controls network card interface chip carries out network service, realizes parsing and the package of the agreements such as address resolution protocol (ARP), Internet Control Message Protocol (ICMP), IP agreement, User Datagram Protoco (UDP) (UDP).Serial ports frame Ethernet being sent buffering area is encapsulated in UDP bag, and passes to IP layer; Meanwhile, receive ethernet data frame and upwards unpack layer by layer, be separated application layer data, then the dissection process of data transfers to Multi-serial port sending module to complete, and realizes the transparent translation of RS232 serial ports stream and ethernet port stream.
The interrupt mechanism priority of this Multi-serial port control module employing microcontroller obtains the serial data frame on medical detecting Instrument; Or described Multi-serial port control module adopts polling mode to give to respond the serial data frame obtained on medical detecting Instrument to each substring mouth.Multi-serial port control module realizes a receipts/control of multiple RS232 serial data stream, comprises the elements such as microcontroller, serial port extended chip (GM8123), MAX232.Microprocessor controls GM8123 completes Multi-serial port data transmit-receive, receives multiple serial ports source data, and after encapsulation, write Ethernet sends buffering area packing transmission; Meanwhile, receive the data of Ethernet application layer, resolve and send to measuring and controlling equipment.It is indifferent to the concrete meaning of communication data, is only responsible for receiving/sending, and encapsulation/seal off serial ports frame, provides general-purpose interface.In the hardware environment that Fig. 4 adopts, have on the basis of 2 UART in the microcontroller, adopt GM8123, system can provide 2 groups (UARTO, UARTl) totally 4 serial ports (COM1, COM2, C0M3, COM4), utilizes the interrupt requests of two-stage two priority classes UARTO with UARTl and allows nested.Inner in the interruption routine of UARTO, be which substring mouth by inquiry mode determination data source.When two groups of serial ports have request of data simultaneously, first, the interrupt mechanism of MCU judges the priority of interrupt requests, the interrupt requests preferential answering high to priority.System is to priority assign: UART0 is 2, UARTl is 1, i.e. the interrupt requests of MCU preferential answering UART0.When there is request of data in 3 rims of the mouth of UARTO simultaneously, by polling mode, each rim of the mouth is responded, namely responded according to the address in rim of the mouth number is ascending.Like this, the Multi-serial port implementation of 2 grades of interruptions and 4 serial ports is just defined.
