Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of serial data communication chain
Road branch cooperative control device.
The utility model provides a kind of serial data communication link branch cooperative control device, including communication module, center
Four processor module, messaging parameter setup module and state instruction modules, the communication module are used for the processing and biography of data
Defeated, the CPU module is used for baud rate, data bit, stops for handling data, the messaging parameter setup module
The effect and matching of stop bit and odd even, the state instruction is for the display in data transmission.
Preferably, the serial data communication link branch cooperative control device, scene does not need to reinstall slave station i.e.
Same set of slave station data can be achieved and provide service for multiple main station systems.
Preferably, the serial data communication link branch cooperative control device, protocol transparent, it is only necessary to which it is logical that serial ports is set
Believe parameter.
Preferably, the serial data communication link branch cooperative control device, not to the communication protocol between master-salve station
It needs to set, compatible almost all of serial communication protocol.
Preferably, the serial data communication link branch cooperative control device, then original system is not produced in being transformed
It is raw to influence.
Preferably, the serial data communication link branch cooperative control device, can directly pre-read according to the numerical value of setting
It takes the data of slave station equipment to go in memory, when main website carries out request of data, directly transmits internal storage data value to main website.
Preferably, the serial data communication link branch cooperative control device, can successively receive the data of multiple main websites
Request returns to the slave station data received according to original route to slave station bus is sent to after the request of data verification of each main website
To the main website of request, each main website is successively handled.
Beneficial effect
The utility model can establish communication scheduling and a data buffer storage between main website and slave station, meet more than two
Main website read slave station data on same bus simultaneously, and there is no conflicts.
Detailed description of the invention

Specific embodiment
Below with reference to the example diagram in the example of the utility model, the technical solution in the utility model is carried out clear, complete
Whole description.The utility model provides a kind of serial data communication link branch cooperative control device, embodiment 1: serial ports number
The request of data that multiple main websites are successively received according to communication link branch cooperative control device verifies the request of data of each main website
After be sent to slave station bus, the slave station data received are returned to the main website of request according to original route, successively handled by slave station bus
Object above can be realized, embodiment 2 in each main website: serial data communication link branch cooperative control device directly according to
The value of setting, the data of pre-read slave station equipment when main website carries out request of data, directly transmit internal storage data value extremely into memory
Main website can reach object above.
Embodiment
As shown in Figure 1, a kind of serial data communication link branch cooperative control device, including communication module, central processing
Four device module, messaging parameter setup module and state instruction modules, communication module are used for the processing and transmission of data, centre

With matching, state instruction is for the display in data transmission.
Preferably, serial data communication link branch cooperative control device, scene does not need to reinstall slave station can be real
Existing same set of slave station data provide service for multiple main station systems.
Preferably, serial data communication link branch cooperative control device, protocol transparent, it is only necessary to which serial communication ginseng is set
Number.
Preferably, serial data communication link branch cooperative control device does not need the communication protocol between master-salve station
Setting, compatible almost all of serial communication protocol.
Preferably, serial data communication link branch cooperative control device, then shadow is not generated to original system in being transformed
It rings.
Preferably, serial data communication link branch cooperative control device, can directly according to the numerical value pre-read of setting from
