As Figure 1-3, the first single-chip microcomputer 11 adopts STC89C51RC-40I-LQFP44 model, the supervisory circuit 14 of this single-chip microcomputer major control indication lamp circuit 13, action button trigger circuit 12 and track switch present position.After connecting general supply, analogue system acquiescence is in positioning states, and by pressing track switch action button and flip operation button simultaneously, analogue system antiposition circuit is started working; After antiposition circuit working is complete, anti-table relay excitation picks up, track switch is in antiposition state, now can press track switch action button and positioning action button simultaneously, analogue system positioning circuit is started working, and trigger button adopts self-resetting type paster button, only has and presses track switch action button and positioning action button simultaneously, circuit just can work, and this kind of mode can realize controlling separately track switch conversion.When goat starts to rotate, after second singlechip 21 is taken orders to the first single-chip microcomputer 11, first single-chip microcomputer 11 by UART serial ports transmission conversion initiation command, control location, reverse indication lamp extinguishes simultaneously, disconnected expression; When goat conversion complete time, the first single-chip microcomputer 11 accept from track switch the converting of second singlechip 21 die order after, control location or reverse indication lamp light, provide expression.Supervisory circuit 14 totally 4 groups, monitor a kind of state for every two groups, when analogue system is in location or antiposition normal conversion process, motor running lamp circuit 23 normally works, if, first single-chip microcomputer 11 detects that goat does not normally work, and this group motor running lamp circuit 23 will glimmer simultaneously, provides miscue.
Second singlechip 21 adopts STC89C51RC-40I-LQFP44 model, primarily of 3 groups of 74HC563 chips and ULN2803 darlington array, and one group of SN74HC138 coding chip, the 1k exclusion of 6 0603 coordinates external circuit.1st switch starting relay (1DQJ) has 3 group relay nodes and 1 group of coil composition, every group node is divided into front and back two parts, every part three LED lamps represent, the front nodal point of all 1 switch starting relays exports control by three signal line of B single-chip microcomputer through ULN2803, all posterior nodal points export control by this three signal line that B single-chip microcomputer is same through 74HC563 phase inverter and ULN2803, and this circuit design achieves two states of a signal line Controlling vertex; 1 switch starting relay has 2 coils, and each coil is represented by 3 LED, and second singlechip 21 exports 6 signal wires and directly controls 2 groups of coils.2nd switch starting relay (2DQJ) design is identical with the 1st switch starting relay design.DBJ (surely showing relay), FBJ (counter show relay) coil circuit and the 1st switch starting relay, the 2nd switch starting relay coil circuit design is identical.Goat internal circuit has four group nodes, and every group node is represented by three LED, and second singlechip 21 exports four signal line and controls this four group node by ULN2803.Motor running lamp circuit is represented by 8 LED, and second singlechip 21 exports three signal line and controls motor 8 running lamps by SN74HC138 code translator, is represented the rotating of goat by the rotating forward reversion controlling running lamp.
Button trigger circuit 12 are made up of self-resetting type button and pull-up 1K resistance; Indication lamp circuit, supervisory circuit is made up of 5mm straight cutting LED, ULN2003-SOP16 driving circuit and 0603-1K paster exclusion.
It is the same that turnout starting relay combination circuit 27 forms with turnout starting relay circuit 24, is made up of trigger key (self-resetting type button) circuit and LED display circuit; Goat internal circuit is made up of 74HC563 inverted chip, ULN2803 large driven current density chip, LED, paster exclusion; Motor running lamp circuit is made up of SN74HC138 coding chip, LED, paster exclusion; Fixed anti-behaviour's relay circuit 25 to be run in resistance by high level, connects trigger key, finally pours into single-chip microcomputer pin, the high level triggering single-chip microcomputer pressed by button; Fixed anti-table relay circuit 26 connects 1K exclusion by high level, then connects LED, and finally connect single-chip microcomputer pin, when after the signal that single-chip microcomputer receives from goat internal circuit end of run, LED is lighted accordingly and extinguished.
This analogue system adopts the lithium battery 32 of 4.2V to power, on pcb board of design, lithium battery charging circuit 31 is based on the lithium battery charging circuit of TP4057 charging chip, when lithium battery does not have electricity, can charge when dismantling lithium battery directly to by USB port.Although the lithium battery of 4.2V can allow LED normal luminous, but consider that analogue system has 103 LED, in order to meet greatest requirements, add the booster circuit 33 of a LM2577, so just can voltage stabilization at 5V, 103 LED can be met to the demand of voltage, ULN2803 chip also can be coordinated better to work, for LED provides more stable electric current.
As shown in Figure 4, below illustrate when control circuit be in determine table status time, analog simulation control circuit is shown surely---instead grasp---instead shows control procedure:
Original state: DBJ coil LED lights, 1DQJ back contact LED lights, 2DQJ normal contact LED lights, DBJ coil LED lights, automatic lid actuator the 1st, 3 groups totally 6 contact LED is lighted, and surely show indication lamp and light, X1-X3 light belt is lighted, all the other LED all extinguish, and current being in of expression system determines table status;
Operating personnel successively must press ZFA and DCA in a certain time interval, assign that track switch is counter grasps order;
After successful operation, surely show pilot lamp and extinguish, anti-behaviour's pilot lamp is lighted, and X1-X3 light belt extinguishes, and X2-X4 light belt is lighted, and FCJ front contact LED lights, and expression system is current is in anti-operating state;
1DQJ 3-4 coil LED connects due to control circuit and lights, and 1DQJ front contact LED lights immediately afterwards, and back contact LED extinguishes immediately, and DBJ coil LED extinguishes;
2DQJ 1-2 set winding LED starts continuous-flow type flicker, represents that 2DQJ starts to turn pole.Turn in the process of pole, 1DQJ 3-4 coil LED extinguishes, but puts effect due to the slow of 1DQJ, and its front contact LED still lights;
After a period of time, 2DQJ turns pole and terminates, and 2DQJ 1-2 set winding keeps Chang Liang, 2DQJ reverse contact LED to light, and normal contact LED extinguishes, and the circle shape LED of simulated machine starts continuous-flow type flicker, while 1DQJ 1-2 coil LED light;
After the flicker of motor LED continuous-flow type, automatic lid actuator the 3rd is arranged contact LED and is extinguished, and the 4th row's contact LED lights simultaneously;
After a period of time, automatic lid actuator first row contact LED extinguishes, and second row contact LED lights simultaneously, represent that track switch moves to assigned position, motor LED extinguishes, and 1DQJ 1-2 coil LED extinguishes simultaneously, because the slow of 1DQJ puts effect, 1DQJ front contact LED still lights;
Delay after putting end, 1DQJ front contact LED extinguishes, and back contact LED lights, and connect the anti-watch circuit of track switch, FBJ coil LED lights, and 2DQJ 1-2 set winding LED extinguishes simultaneously, and track switch course of action completes;
Afterwards, FCJ coil LED extinguishes, and anti-behaviour's pilot lamp extinguishes, and anti-table pilot lamp is lighted, and X2-X4 light belt extinguishes, and X2-X3 light belt is lighted, and control circuit is shown surely---instead grasping---, and anti-table simulation simulation process terminates.
------determine table simulation simulation process and determine table---instead grasping---instead shows similar fixed behaviour the anti-table of control circuit, does not repeat them here.
