Description

Intellectual power supply timing switch controller

The utility model belongs to power supply timing switch control appliance and makes the field.

The power supply timing switch controller of present existing all styles of all can not be accomplished the multi-period accurate switch control to multiple power supplies.

The purpose of this utility model is a kind of intellectual power supply timing switch controller of design, makes it to have the ability to work of multiple power supplies being carried out multi-period accurate timing switch control.

The purpose of this utility model is to realize by following design.

Intellectual power supply timing switch controller is made up of timing circuit and control executive circuit based on microprocessor.Wherein, timing circuit is made up of microprocessor, RAM, EPROM, electrify restoration circuit, crystal oscillating circuit, display interface circuit, display, keyboard interface circuit, keyboard and control signal output circuit; The control executive circuit is made of the relay of photoelectric isolating circuit and execution mains switch.

After adopting as above structure, under the support of the control program in leaving EPROM in, the user is provided with the power supply and the period of current time, the control of selection need by keyboard, under the control of microprocessor CPU, make the control signal output circuit produce corresponding switching signal at preset time, this signal makes corresponding power supply timing switch through the control executive circuit.

Adopt the utility model can carry out multi-period accurate switch control to the power supply of a plurality of electrical equipment, and has a versatility widely, both can use separately, also can be used as intellectual timing control unit and be used in combination, the power supply of various industrial electrical equipments and household electrical appliance is carried out intelligentized timing switch control with other power equipment.

Description of drawings is as follows.

Fig. 1 is the key wiring diagram of the utility model embodiment timing circuit.

Fig. 2 is the key wiring diagram that the utility model embodiment controls executive circuit.

Below in conjunction with accompanying drawing the utility model is described in further detail.

In Fig. 1, form timing circuit by electrify restoration circuit 1, crystal oscillating circuit 2, microprocessor 3, RAM4, EPROM5, display interface circuit 6, display 7, keyboard interface circuit 8, keyboard 9 and control signal output circuit 10.After powering up, electrify restoration circuit 1 resets microprocessor 3, RAM4 state, and begin to carry out the program that is preset at the EPROM5 from the address 0000H of EPROM5, crystal oscillating circuit 2 is used to carry out routine processes for microprocessor 3 provides external timing signal, microprocessor 3, comprise the time of accepting clock interruption, program timing, having judged whether the timing switch power supply, if to the scheduled time, then send control signal corresponding to control signal output circuit 10.The information that need such as the current time that display interface circuit 6 is used for microprocessor 3 is sent, timing, operation indicating, running status show is delivered to display 7 and is shown.Keyboard interface circuit 8 is delivered to the signal of keyboard input microprocessor 3 and is handled, to differentiate key number and to carry out the correspondent button intended function.As: clock is set, select to need control power supply, select the period, timing is set, begins to carry out etc.Control signal output circuit 10 is used for output in program process, the control signal of the Switching Power Supply of being sent by microprocessor 3.

The control signal that timing circuit provides realizes mains switch control by relay circuit 12 after photoelectric isolating circuit 11 photoelectricity of control executive circuit are isolated.Its key wiring diagram as shown in Figure 2.Wherein, K1～K16 is that (normal opened contact of J1～J16), Z1～Z16 is the binding post of 16 charged power circuit in parallel with K1～K16 respectively to 16 relays.

As control signal OCi (1≤i≤16) when being high level, the coil of relay J i powers up, normal opened contact Ki (1≤i≤16) closure, and Zi connects; When control signal OCi is low level, the coil losing electricity of relay J i, Zi disconnects.Consider when reality is used, be not to need at any time every road power supply is carried out timing switch control, so as shown in Figure 2, control is provided with in the executive circuit to have timing controlled and enables/the control branch road of cancellation function, and this control branch road is actually respectively the hand switch with maintenance function that is in parallel with K1～K16 (B1～B16).As Bi (1≤i≤16) when pressing, Zi is connected by force, by the relay normally open contact Ki of timing circuit control whether folding do not influence the break-make of i road power supply; When Bi upspring, whether Zi was switched on by timing circuit and the control of control executive circuit.

The working power of timing circuit and control executive circuit can be obtained through conventional transformation, filtering and rectification by the input power supply.Because clock and timing information that temporary interruption causes are lost, can adopt conventional battery for avoiding as standby working power.

According to basic scheme of the present utility model, can make many different embodiment in conjunction with routine techniques in force.
