Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.
Hardware circuit of the present invention as shown in Figure 1, it is the MCU chip realization of PIC16F676 that processor UM1 adopts a model, its 7 pin connects the specific keys testing circuit, specific keys and standby key-press sharing among the present invention, the standby button of promptly selecting electric equipment is as described specific keys, realize electric equipment when interchange powers on, effective switching of system works pattern by the lasting compressing time that detects the standby button.2 pin of described processor UM1 receive the remote-controlled start-up instruction of remote-control receiving circuit output, and 6 pin are to main power relay output high level or low level control signal, and whether the control main power circuit starts work.8 pin receive the holding state signal that host CPU sends, and when being low level, the expression system is in the start normal operating conditions; When becoming high level by low level, the expression system receives shutdown command, and then passes through the 6 pin output low levels of processor UM1, and control apparatus equipment enters holding state, and the running status that powers on of system is set to standby mode.
After the electric equipment interchange powers on, at first judge the residing mode of operation of system,, then directly export the high level starting-up signal by 6 pin of processor UM1 if be in the automatic start-up mode that powers on, control main power circuit operate as normal is for each circuit module in the electric equipment provides working power; If system is in when powering on standby mode, the 6 pin output low level standby signals of processor UM1, primary power is not worked, when 2 pin of processor UM1 receive the remote-controlled start-up instruction, perhaps 7 pin receive level standby button from high to low when pushing signal, when perhaps receiving the starting-up signal that external unit sends by the RS232 serial ports, then processor UM1 controls its 6 pin to main power circuit output high level starting-up signal, and control apparatus equipment is in normal operating conditions.
Described processor UM1 detects the level state of its 7 pin in real time, when continuing the time of pressing, the standby button reaches setting-up time in the time of 20 seconds, the processor UM1 system pattern of working on power is set to automatic start-up mode, and this state under the memory, exchanges the back system that powers on afterwards and starts automatically.But when 8 pin of processor UM1 received by the low shutdown pulse command signal that uprises, system just broke away from this automatic start-up mode, and exchanged the back system that powers on afterwards and enter the low-power consumption standby pattern automatically.
The received shutdown command signal of 8 pin of processor UM1 can provide by three kinds of modes, a kind of is to export off signal by the switch for the treatment of on the telepilot, another kind is to export off signal by the switch for the treatment of on the electric equipment, the third is to connect external unit by the RS232 serial ports that is provided with on the electric equipment, and then receives the off signal that external unit sends.Off signal from three aspects receives by the host CPU in the electric equipment, outputs to 8 pin of described processor UM1 after it is handled.
In order to make described processor UM1 finish state-detection proposed by the invention and memory function, portion has write corresponding software programs within it, comprise three parts on the whole: one, key-press status detecting unit, detect in real time the standby button and continued time of pressing, promptly 7 pin of processor UM1 are continuously the low level time; Two, judging unit, the time and the 20 seconds predefined time that continue to press are compared, according to comparative result the electric equipment mode of operation that the back system enters automatically that powers on next time is set specifically, promptly 7 pin level are continuously the low time when surpassing 20 seconds, system enters the automatic start-up mode that powers on, otherwise, keep original mode of operation; The shutdown command receiving element when receiving shutdown command, is provided with the electric equipment back system that powers on next time and enters standby mode automatically.Its specific procedure FB(flow block) is referring to shown in Figure 2.
Among Fig. 2, after electric equipment exchanged and powers on, processor UM1 got electric work, its internal processes initialization, and concrete operating procedure is as follows:
A, detection system work at present pattern, if automatic start-up mode, the 6 pin current potentials of then putting processor UM1 are high level, the work of control apparatus device power-up; Otherwise, enter standby mode;
The Anti-interference Design of b, input signal;
Whether the 8 pin current potentials of c, measurement processor UM1 are low level, if low level shows the operation of starting shooting of present electric equipment, jump to d; Otherwise whether the 7 pin current potentials of measurement processor UM1 are low level, promptly whether press the switch for the treatment of on the electric equipment, if then jump to h; Otherwise, jump to f;
Whether the 8 pin current potentials of d, real-time measurement processor UM1 are high level, if high level promptly receives shutdown command, judge then whether system is in the automatic start-up mode that powers on, if withdraw from this mode of operation, enter the standby mode that powers on, and remember this mode of operation, change e over to; Otherwise, directly change e over to; As if 8 pin current potentials is low level, then repeating step d;
E, the 6 pin current potentials of putting processor UM1 are low level, turn-off the electric equipment primary power; Return step b;
Whether 2 pin of f, measurement processor UM1 receive the remote-controlled start-up instruction, if jump to h; Otherwise, jump to g;
Whether the RS232 serial ports of g, detection electric equipment receives the start-up command that external unit sends, if jump to h; Otherwise, jump to b;
H, the 6 pin current potentials of putting processor UM1 are high level, the work of control apparatus device power-up;
The 7 pin current potentials of i, measurement processor UM1 are continuously the low level time, if greater than 20 seconds, then system enters the automatic start-up mode that powers on, and remembers this mode of operation, returns step b; Otherwise, directly return step b.
The present invention adopts the above-mentioned simple software and hardware mode of combining to realize the multimode requirement of electric equipment operation, has satisfied the dual purpose that Workshop Production efficient and user security use.In the Workshop Production process, in order to enhance productivity, save commissioning staff's on time, system is operated in to power on start mode of operation automatically, as long as to the electric equipment Alternating Current Power Supply, i.e. controllable device starting up voluntarily.Directly cut off AC power, can guarantee that electric equipment start next time still is operated in the startup mode of operation automatically that powers on.Before the electric equipment debugging finishes, dispatches from the factory, press the standby button on the telepilot, make system break away from this mode of operation, enter the stand-by operation pattern that powers on, thereby satisfied the requirement of using required powering on to enter the standby low power consumpting state in the user family.
Technical scheme of the present invention can realize by revising the internal software program on the basis of the original basic circuit of electric equipment, both saved hardware cost, realized the multimode requirement of electric equipment operation again, especially be fit to be applied in the audio/video media equipment such as televisor.
Certainly; above-mentioned explanation is not to be limitation of the present invention; the present invention also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
