Summary of the invention

The objective of the invention is provides a kind of Lift voice broadcast method that carries out signal conditioning and control broadcast that can be real-time automatically at above-mentioned problems of the prior art.

For realizing purpose of the present invention, the invention provides a kind of Lift voice broadcast method, this method may further comprise the steps: (1) initialization, get settled preceding floor; (2) scanning elevator panel, and quantize all destination information that the storage user chooses; (3) the destination data sorting for storing; (4) judge whether to exist actv. destination information, if judged result is then returned step (2) for not; (5) if whether the result who judges in the step (4) for being, detects relevant gate signal, if testing result is then returned step (2) for denying; (6) if the result who detects in the step (5) is for being that the judgement ascending for elevator still is descending; (7) judge nearest destination of elevator and preservation; (8) call and select sound to play subprogram; (9) preserving the nearest destination of elevator of having play voice is current floor.

When the said elevator sound broadcasting device of the present invention moves in above-mentioned mode, can adapt to particular user and report content, voice broadcast service timely automatically is provided.

The present invention will be elaborated with reference to accompanying drawing in conjunction with the embodiments, so that to purpose of the present invention, feature and advantage are carried out more deep understanding.

Description of drawings

The structural representation of Fig. 1 elevator sound broadcasting device;

The diagram of circuit of Fig. 2 embodiment of the invention;

The sound that selects of the first location stage extraction voice of the nothing of Fig. 3 embodiment of the invention is play subroutine flow chart.

The specific embodiment

As shown in Figure 1, the utility model comprises audio power amplifier circuit 5, and the elevator signal Acquisition Circuit 1 of Lian Jieing, system's buffer circuit 2, micro controller system and peripheral circuit 3 thereof, mouth connect the sound chip circuit 4 of audio power amplifier circuit 5 successively.This specification sheets alleged " elevator panel " is meant button, the display part that elevator customer can contact, and the number of floor levels keyboard that the user presses on the elevator panel is chosen the respective objects floor." elevator control panel " is meant the sightless circuit board section of elevator panel subsequent user.Elevator signal Acquisition Circuit 1 is taken out elevator up-down signal, pass gate signal and floor signal in elevator control panel, after process system buffer circuit 2 is handled in modes such as photoelectricity isolation, send into micro controller system and handle by the parallel I/O mouth of micro controller system by it, promptly support with programming mode realize under the Single-chip Controlling to elevator panel scanning collection signal.Micro controller system is handled back control sound chip circuit 4 to signal, by audio power amplifier circuit 5 playbacks.Obviously in actual applications, also need arrange in pairs or groups corresponding transforming circuit and power amplifier.

As shown in Figure 2, after the elevator sound broadcasting device powered on, in step 11, settled preceding floor was got in the unit zero clearing that will use in the internal storage (RAM) of initialization section with micro controller system.In step 12, the scanning elevator panel also quantizes all destination information (the number of floor levels keyboard that the user presses on the elevator panel has promptly been chosen the respective objects floor) that the storage user chooses.In step 13, for being stored in the destination data sorting in the internal RAM, quantize the number in each destination corresponding stored unit, storage back, the number (maximum number) i.e. in first memory cell of ordering back is the highest destination of representative.In step 14, judge whether to exist actv. destination information, if judged result is for denying, then return step (2), promptly check the number in first memory cell, this number is that zero expression does not have the highest destination (not having the number of floor levels keyboard to press), and there is the highest destination (having the number of floor levels keyboard to press) in non-vanishing then expression.In step 15, if whether the result who judges in the step 14 for being, detects relevant gate signal, if testing result is then returned step 12 for denying; In step 16, if the result who detects in the step 15 is for being that the judgement ascending for elevator still is descending; In step 17, the up floor big and minimum (17a) of then finding out than current floor, descending words are just found out than the current little and the highest floor (17b) of layer of hugging, and promptly judge the nearest destination of elevator, and preserve.In step 18, call and select sound to play subprogram.In step 19, preserving the nearest destination of elevator of having play voice is current floor, so that provide comparison for broadcast next time.After finishing once broadcast, program is returned step 12, can realize the real-time voice report automatically and continuously.

The speech chip of the elevator sound broadcasting device of the embodiment of the invention adopts the ISD4004 series of Winbond company.This chip recording voice does not have segment length restriction, SoundRec not to need A/D conversion and compression, and it is long to have a writing time, uses multiple advantages such as required peripheral circuit is simple.For ISD4004, because the content of two less important broadcasts might not be two neighboring sections in memory device, for this situation, if under the situation of knowing each voice segments first address, can directly adopt the order of " send this section first address and begin playback " to realize from the current address, if do not know the first address of each section, can take the mode of continuous F.F. to realize, the sound that selects that the specific embodiment of the invention provides an a kind of mode later on to extract voice is play subprogram, and system determines to call this subprogram behind the nearest destination of elevator.As shown in Figure 3, in step 21, the backup nearest destination of elevator (i.e. the floor that will broadcast) is done a backup so that playback is saved in current floor memory cell after finishing, and according to the nearest destination of elevator F.F. time counter is set.In step 22, speech chip to be done power down power on processing so that speech chip resets, the back current speech sector address that resets is initial position (being that the address is 0 place); In step 23, to the order of speech chip transmission by current voice segments address F.F., F.F. time counter subtracts 1.In step 24, detect the voice segments address that whether arrives the nearest destination of elevator, i.e. whether the numerical value of F.F. time counter is 0, then returns step 23 if not.In step 25, if the result who detects in the step 24 is for being broadcast voice (speech chip being sent the order of " beginning playback from the current speech sector address ").Select sound to play to get back to system's main program after the end of subroutine and carry out step 19.
