Abstract
The utility model provides a kind of multi-channel serial port controller, including control IC and power supply terminal, IO leading-out terminals, IO input terminals, several RS232 serial ports independently to work and the network interface and USB interface that are connect respectively by match circuit with control IC；Wherein, control IC reads IO inputs or control IO outputs according to host computer order；Serial port command data from network interface or USB interface are sent to one or more purpose RS232 serial ports by control IC, and the data of purpose RS232 serial ports can be by controlling IC to return to USB interface.Using the technical solution of the utility model, it can not only realize the IO control functions of basic general industry controller, and host computer or other controllers can also control this controller by network interface or USB interface, and further complete the data transmission between purpose RS232 serial ports and USB interface, so as to realize the control of multi-channel serial port simultaneously on the basis of IO controls, meet the situation of the diversification of demand instantly.
Description
Technical field
The utility model is related to a kind of controllers, and in particular to a kind of controller with multi-channel serial port.
Background technology
Serial ports controller is exactly the controller that control function can be realized by serial ports, i.e., is sent out by host computer by serial ports
The instruction of specific protocol form is sent to controller, and then to control peripheral equipment or device.Although at present applied to each field
Controller is various, but most classes are single, function is simple, can not cope with diversified, complication using needs.Currently in industry
Control industry needs are a kind of can be controlled multi-channel serial port simultaneously and can have both the controller of IO control functions.
Utility model content
The purpose of the utility model is to overcome shortcomings in the prior art, provide a kind of support while control multichannel
Serial ports and the multi-channel serial port controller for having both IO control functions.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of multi-channel serial port controller, including control IC and the power supply being connect respectively by match circuit with control IC
Terminal, IO leading-out terminals, IO input terminals, several RS232 serial ports and network interface and USB interface；The control IC passes through network interface
Or USB interface is connect with host computer.
Further, IO input terminals are inputted for 8 digital switch quantities, and IO leading-out terminals are exported for 12 digital switch quantities.
Further, control IC can also be according to operation all peripheral hardwares of program autonomous control.
Further, the RS232 serial ports is altogether 4, two is set respectively in the both sides of circuit board, in the another of circuit board
Outer both sides set IO input terminals and IO leading-out terminals respectively.
Further, the USB interface is in the same side with IO input terminals.
Using the technical solution of the utility model, the IO control work(of basic general industry controller can be not only realized
Can, and host computer or other controllers can also control this controller by network interface or USB interface, complete purpose RS232 strings
Data transmission between mouth and USB interface；Also or according to operation all peripheral hardwares of program this controller autonomous control, so as to have both
IO is controlled and the control of multi-channel serial port, meets the situation of the diversification of demand instantly.Meanwhile the technical program makes full use of existing electricity
Sub- technology, it is of low cost, it is simple and practical, there are good economic results in society.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of the utility model.
Specific embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
With reference to attached drawing.The utility model includes control IC1 and the confession being connect respectively by match circuit with control IC1
Electric terminal 2, IO input terminals 3,4, four RS232 serial ports 5 independently to work of IO leading-out terminals and network interface 6 and USB connect
Mouth 7, network interface 6 are network interface, and the control IC1 is connect by network interface 6 or USB interface 7 with host computer, and power supply passes through feeder ear
2 pairs of this controller power supplies of son；By above-mentioned connection structure, control IC1 can read IO inputs or control IO according to host computer order
Output, host computer or other controllers can control this controller by network interface 6 or USB interface 7, and control IC1 can will come from network interface 6
Or the data of USB interface 7 are sent to one or more purpose RS232 serial ports according to order demand, can obtain purpose RS232 serial ports
The data obtained return to USB interface 7.
Particularly, IO input terminals 3 are inputted for 8 digital switch quantities, and IO leading-out terminals 4 are exported for 12 digital switch quantities, can
It is needed to connect required amount of input and output according to practicality.
For four RS232 serial ports 5, two are set respectively in the both sides of circuit board, in the other both sides of circuit board
Setting IO input terminals 3 and IO leading-out terminals 4 respectively.The USB interface 7 is in the same side with IO input terminals 3.
Particularly, this controller can also be according to operation all peripheral hardwares of program autonomous control.
It should be pointed out that the embodiment be described above the utility model.However, the technical staff of art technology should manage
Solution, the present utility model is not limited to the above embodiments, the principle for only illustrating the utility model described in above-described embodiment,
There are many changes and improvements for the utility model also meeting under the premise of the scope of the utility model is not departed from, these changes and improvements are all
It falls into claimed the scope of the utility model.
