Embodiment

Below in conjunction with accompanying drawing the utility model is done further explain based on the four-way switch amount input media of bus mastering mode.

As shown in Figure 1, based on the four-way switch amount input media of bus mastering mode, mainly comprise control bus, bus coupler, direct supply, single-chip microcomputer and No. four relay output circuits composition.

Control bus is a kind of bus intelligent control system, and it can connect multiple functional module, and is linkage between the module, can become the intelligent body of an independent operating again.

Bus coupler is responsible for and the control bus communication, receives from the communication signal of control bus and gives single-chip microcomputer, and the response signal of single-chip microcomputer is sent on the control bus.

Single-chip microcomputer receives the communication command from control bus, according to command context No. four relay output circuits is controlled.

Direct supply is provided by control bus, and direct supply converts into+5V power supply supply single-chip microcomputer and bus coupler use through power conversion chip.

As shown in Figure 2, it is main control chip that U1 adopts the MC9S08AW32 single-chip microcomputer of Freescale, and U2 is a bus coupler, and R5 and LED1 constitute the operation indication, and K1 is a feeler switch.

As shown in Figure 3, power circuit converts DC24V to DC5V and supplies this device to use, and circuit has anti-reverse defencive function, when outside DC24V connects in the other direction, can not damage internal circuit.

As shown in Figure 4, RLY1-RLY4 is four relays, and its electric current of make-and-break can reach 20A.U5 is the relay control chip, and it receives Single-chip Controlling, can control the break-make of No. four relays, and RV1-RV4 plays contact protection and suppresses the switch interference.

The preferred embodiment of below the utility model having been created specifies; But the utility model is not limited to embodiment; Those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the utility model creative spirit, modification that these are equal to or replacement all are included in the application's the scope.
