Communication controler

Technical field

The application relates to circuit board control device, especially communication controler.

Background technology

At present, flourish along with computer and electronic technology, automated control technology is used widely.In medium and small test macro exploitation, main realization rate is the circuit board developing corresponding function according to the actual requirements, realizes corresponding function.This realization rate cost is low, but debugging trouble, risk is comparatively large, requires also higher to technical staff, and disadvantage is exactly need from newly designing and developing according to difference in functionality demand, and recycling rate of waterused is low.

Summary of the invention

The object of the application is to overcome deficiency of the prior art, communication controler is provided, communication interface, controller and control pedestal can be provided for the exploitation of other function module circuit plate, designer can design corresponding embedded functional module board on the basis of this circuit board, develops respective control system; Avoid the trouble brought because different control system's development correspondence repeatedly develops, eliminate repeatability, reduce development cost and shorten the development time.

The application to achieve these goals, adopts following technical scheme: communication controler, is by power interface, parallel interface bi-directional communication modules, controller module, mother socket module, supply line, chip selection signal line, handshake line, low 8 bit address lines, uneven bottoms line, external interrupt lines, control line, gathering line, reads control line, write line, high 8 bit address lines, 8 position datawires, substrate is formed; A bight of the substrate of rectangle arranges power interface, and the below of power interface arranges parallel interface bi-directional communication modules, and the side of parallel interface bi-directional communication modules arranges controller module, and the opposite side of controller module arranges mother socket module.

Supply line is arranged in parallel between power interface and parallel interface bi-directional communication modules, controller module, mother socket module; The output of controller module is disposed in parallel in the input of parallel interface bi-directional communication modules by chip selection signal line, handshake line, low 8 bit address lines.

The input of controller module is disposed in parallel in the output of mother socket module by uneven bottoms line, external interrupt lines, gathering line; An output of controller module is arranged on an input of mother socket module by control line.

The output of controller module by read control line, write line, high 8 bit address lines side by side after be arranged in parallel input in parallel interface bi-directional communication modules and mother socket module.

The bidirectional port of controller module is arranged in parallel the bidirectional port in parallel interface bi-directional communication modules and mother socket module by 8 position datawires.

Described controller module is the core of system, it with 80C196KB single-chip microcomputer for core processor, with

EPM7128SLC type CPLD and other integrated chip are the work of additional device coherent system.80C196KB is a 16 CMOS single-chip microcomputers that Intel company produces, and has 8 and 16 two kinds of mode of operations, adopts 8 mode of operations here.EPM7128SLC is mainly used to as decoding circuit, and system leaves JTAG mouth, and user can online modification according to demand.80C196KB adopts hand-reset mode, uses monostable flipflop 54HC123 to realize, and single-chip microcomputer adopts In-line Memory 28C64B as external program memory, and memory space is 4kbit, facilitates the erasable replacing of program.Single-chip microcomputer provides uneven bottoms interface, external interrupt interface and external control line; leave 8 simultaneously and gather port; gather port and be designed with voltage-stabiliser tube protective circuit; gathering reference voltage is+5V, and user can realize 8 or 10 A/D drainage patterns by arranging Chip Microcomputer A/D register AD_COMMAND.

Described parallel interface bi-directional communication modules sets up the passage communicated between single-chip microcomputer with computer.Its interface plays vital effect in systems in which as the passage of the exchanges data of computer and single-chip microcomputer.Both sides realize asynchronous high-speed traffic by handshake, by parallel interface bi-directional communication modules, computer not only can carry out the operations such as instruction control and reading and writing data to the embedded hardware circuit of communication controler, and the data parameters of each embedded circuit board can also be read from communication controler, and then judged, identified.Design adopts dual-ported memory IDT7130, latch 54HC273 and buffer 54HC245 is as main element, realizes the exchanges data of computer and single-chip microcomputer.Single-chip microcomputer carries out read-write operation by the A mouth of dual-ported memory IDT7130, and computer then carries out read-write operation by the B mouth of IDT7130

The beneficial effect of the application is: structure is simple, installs exploitation conveniently, is convenient to promote, increases work efficiency, saved production cost and time.In aerospace system, all there is good application, and also can apply in the army and the people produce.
