[embodiment]

Please in conjunction with consulting Fig. 6 and Fig. 7, the present invention is a kind of to test the method and apparatus of all kinds of electric appliance remote controller functions, and it comprises pilot lamp display circuit 1, Keysheet module 3, single-chip microcomputer IC1, remote control receiver module 2, single-chip microcomputer oscillatory circuit 4, type sequence number display circuit 1, telepilot sequence number display circuit 8 and external memory storage circuit 6.Pilot lamp display circuit 1 comprises pattern pilot lamp LED1 and qualified pilot lamp LED2, and when the P10 of IC1 pin output high level, the emitter follower (raising carrying load ability) through Q1 forms makes pilot lamp LED1 bright, otherwise, P10 pin output low level, pilot lamp LED1 is dark.The circuit theory of qualified pilot lamp LED2 and last same.Keysheet module 3 comprises the function selecting key circuit, be respectively SW1 " pattern " key circuit, SW2 " type selection " key circuit, SW3 " test again " key circuit, the circuit form of each key is the same, be example with the SW1 key circuit below, when the SW1 closure that is pressed, the P15 pin input low level of single-chip microcomputer IC1 then is if the SW1 key unclamps, then because the R6 resistance is less, 5V voltage is input to the P15 pin of IC1 through resistance R 6.

R5, C1 form power source deoupling circuit in the remote control receiver module 2, the task of this module is that the infrared remote-controlled signal of the telepilot that receives is imported from the P16 pin of single-chip microcomputer IC1 through the serial telecommand sign indicating number of demodulation, shaping output, and the IC1 single-chip microcomputer is analyzed this order code again.Single-chip microcomputer oscillatory circuit 4 uses the 8M crystal oscillator.Reset circuit of SCM 5 resets for the powered on moment low level, and then 5V charges to C4 by R9 voltage, and the RESET pin of IC1 becomes high level.

External memory storage circuit 6 is prior aries, comprises latch IC2 and external memory storage IC3, and 17 pin, 16 pin of IC1 are respectively the reading and writing pin, and 30 pin are the latch signal output pin.1 pin of IC2,20,22 pin of IC3 are for enabling pin, and low level is effective.The address signal of external memory storage IC3 is from P00 mouth and the P02 mouth of single-chip microcomputer IC1, and the least-significant byte address of memory IC 3 is sent by P00 mouth timesharing (address/data).For address signal in the whole cycle of reference-to storage IC3 remains unchanged, the least-significant byte address latch that the P0 mouth is exported earlier must be got up (finishing) by IC2.Like this, on the one hand abdicating the P00 mouth, make the P00 mouth can send data-signal once more, is that the high address of the low order address of IC2 latch output and the output of P02 mouth is realized the visit to the memory inside storage unit together on the other hand.

What type sequence number display circuit 7 adopted is seven sections light-emitting diode displays, its circuit also is a prior art, the 74164th, string and conversion chip, the serial data that shows is by A, the input of B pin, export to 7 sections light-emitting diode displays by Q0～Q7 pin after converting parallel data to, 74164 CLK pin is the synchronous shift clock pin of serial, and 9 pin are and clear 0 pin of line output, low level is clear 0, so this pin of this circuit connects high level.Data move into from A, one one ground of B pin under the effect of CLK pulse.74LS32 be or the door, 10 pin of IC1 are the serial data output pin, are defeated by A, the B data input pin of IC7, IC8,11 pin of IC1 are the shift clock output pin.Before IC1 will export machine model data and shows for machine model display circuit 7, allow the 15 pin output low levels of IC1 earlier, 14 pin output high level, clock signal enters IC4, IC5 or door, like this through or the door IC4 3 pin clock signals, under the cooperation of clock, the machine model data parallel to be shown of 2 bytes (16) outputs to two " type sequence numbers " 7 sections LED and goes up demonstration, and data are refreshed.And 2 pin of IC5 are because input high level, and the 1 pin time clock that is input to IC5 be cannot get through, and 3 pin are exported the CLK pin that high level all the time inputs to IC8, IC9, and the therefore original key number that shows is according to constant.Otherwise, if display key number (also being referred to as the button sequence number) data and the demonstration of machine model (also being referred to as the type sequence number) is constant, then allow 15 pin of IC1 export high level earlier, 14 pin output low levels, make the CLK pin of IC6, IC7 when IC1 serial run-out key video data, be always high level, the machine model shows still constant like this, and because the 14 pin output low levels of IC1, the shift clock of IC1 output normally enters the CLK pin of IC8, IC9, meanwhile wants one one ground of data presented to move into 74164 and shows.

Please consult Fig. 1 to Fig. 5 and Fig. 6 again, a kind of method that can test all kinds of electric appliance remote controller functions of the present invention is divided into test pattern and mode of learning.

The workflow of test pattern is as follows: opening power then enters test pattern automatically, and the type sequence number shows " 01 ".The pattern pilot lamp does not work under the test pattern, select type sequence number (the i.e. telepilot that selection will be tested by " type selection " key earlier, decision when which machine model the telepilot of testing is kept on by study, this device can be stored 15 kinds of telepilots, the power down data are not lost, whenever press once " type selection " key, " type sequence number " demonstration adds 1, when demonstration " 15 " will be returned demonstration " 01 " by primary key again.The signal that telepilot sends is received by the remote control receiver module, we are referred to as the telecommand sign indicating number through the signal of this module demodulation output, whenever press once " type selection " key, the pointer that points to external memory instruction code table will be adjusted to the order code heading address of corresponding type, just " qualified indication " lamp is bright during format device power supply, promptly this external memory stores has the instruction code table of the telepilot of 15 kinds of types, and it demonstrates character " 01 " respectively at correspondence in the type sequence number display circuit 7 and arrives " 15 ".During test, press certain key of tested telepilot, on " button sequence number " seven sections light-emitting diode displays, show corresponding key sequence number (the button sequence number is defined under mode of learning in order by the user) immediately, unclamp then " button sequence number " display deepening of button, when first key is pressed and receives signal, " qualified indication " lamp is by bright deepening, this lamp only is pressed and each " button sequence number " just brightens after all showing once more at all keys of telepilot, shows that each key of this telepilot has all recognized.If press the remote controller key that other can not be identified, " button sequence number " display will not have any reaction and will not show.If telepilot user thinks that by crossing all keys, " qualified indication " lamp is but also not bright, shows that certain button has fault or user to leak by certain key, can press " restarting " key this moment makes " qualified indication " lamp can test again by secretly brightening.

The workflow of mode of learning is as follows: promptly be transformed into mode of learning by " mode switch " key, " pattern indication " lamp is bright under the mode of learning, pressing each key successively learns, show " 01 " by first key " button sequence number " display, whenever press primary key below, " button sequence number " display is by " 02 ", " 03 " ... add 1 successively, (whenever press primary key, receive the order code that telepilot sends, and be saved in external memory, the next storage space of software distribution is to wait for the order code of next key simultaneously).Suppose that by certain key display increases progressively and is shown to " 06 ", this key sequence number will be defined as " 06 ", will show " 06 " by this key under test pattern.If after having learnt to need the button of test, return test pattern by " mode switch " key, the pattern lamp goes out, and qualified pilot lamp is bright.In the present embodiment, if this telepilot surpasses 64 keys, this device can return test pattern (this device can not be tested the telepilot more than 64 keys) automatically when having learnt the 64th key.

Consult accompanying drawing 1 to Fig. 4, external memory is also stored 15 kinds of types except the order code of the telepilot of storing 15 kinds of types remote controller key mark of conformity position, the mark of conformity position of every kind of type has 64,64 mark of conformity positions of the selected machine model of memory.The corresponding mark of conformity of external memory position is by clear 0 when pushing remote controller key under the mode of learning, and internal memory correspondence mark of conformity position was by clear 0 when test pattern press remote controller key down.The state of external memory mark of conformity position in the accompanying drawing the 4, the 5th, certain type, from the external memory state as can be seen this telepilot have only 7 keys, then the 0th quilt of external memory the 0th byte is clear 0 by first key during study, subsequently by the 2nd, 3,4,5,6,7 then corresponding the 1st, 2,3,4,5,6 sequential order of key by clear 0; The 3rd key of hypothesis telepilot recognizes and is pressed during test, the 2nd quilt clear 0 of the 0th byte of corresponding internal memory then, whenever the position that recognizes a key internal memory correspondence is by clear 0, meanwhile every clear 0 once, whole 64 button mark of conformity positions all will compare 64 button mark of conformity positions that should type with external memory, if all equate then qualified pilot lamp lights, show that each key of this telepilot all is identified, can test next telepilot this moment, when first key of next telepilot is pressed moment qualified lamp by bright deepening, 64 mark of conformity positions 1 of internal memory, if first key is identified, then corresponding position is equated up to 64 of interior external memory once more by clear 0, qualified lamp just brightens again, waits next telepilot to be tested again.If pressed all remote control keys, malfunctioning unrecognized arriving of key is arranged, then qualified pilot lamp does not work, be judged to bad telepilot, and then should make qualified lamp bright, to 64 mark of conformity positions 1 of internal memory by " test again " key of this device before surveying next telepilot.

This invention can be tested the telepilot of different types of machines, has versatility, so reduced cost, new telepilot then can be tested by instruction code table and mark of conformity position that mode of learning is stored this type; Because adopt circuit to carry out dependence test, avoided because of existing electrical equipment problem of slow response, thereby improved detection efficiency; By the setting of display device, make that testing result is easier intuitively to be obtained, thereby reduced false failure rate.
