Embodiment

The total system structure as shown in Figure 1, single-chip microcomputer Mcs51, Msp430, the Upsd3434 wider by current use constitute multi-single-chip microcomputer system, the control core of this system is made up of three single-chip minimum systems, each Single Chip Microcomputer (SCM) system has independence, and each module can interconnect by open terminal.

Peripheral module is made up of LED light, infrared interface, charactron interface, Liquid Crystal Module, matrix keyboard, 8155 extension sockets (advancing directly to insert 8155 row I/O mouth expansions), loudspeaker, serial ports, control circuit.Because the I/O mouth of Msp430 and Upsd3434 single-chip microcomputer is 3.3v mostly, therefore extended out a slice conversion chip 1v4245.On connecting, all adopted Open architecture, promptly be connected on the open terminal, can easily module have been connected and remove.

The single-chip minimum system module is the minimum system figure of MCS51 as shown in Figure 2, wherein has Y1, C4, C5 to constitute oscillatory circuit, and K1, R2, C8 constitute reset circuit.Added 6 button K2-K7 to realize the function debugging in the control at the P3 mouth in addition, these buttons can not use when using second function of P3 mouth, with anti-collision.The socket at this place can insert the MCS51 chip of all pin compatibilities in the circuit board.

Figure 3 shows that the minimum system figure of upsd3434, system constitutes oscillatory circuit by Y1, C5, C6, L1, C4, and (annotate: the interface circuit that this figure provides with reference to ST company), wherein L1, C4 also can remove.Reset circuit is made of R3, D1, S1, C7, and S1 realizes hand-reset.

LED light module as shown in Figure 4: use eight light emitting diodes to constitute, can detect the state of one-chip machine port in the debugging of control system, P15 is an open terminal, and is easy to connect with the control mouth.
