Description

The telechiric device of two codec controls

Affiliated technical field:

The utility model is the telechiric device about two codec controls, particularly utilizes two pairs of codecs to control a kind of device of realizing distant control function jointly.

Technical background:

General encoding and decoding digit chip, for example: PT2262, PT2272, widespread usage is in the design of remote control circuits such as coded lock, controller, lamp switch.The encoding and decoding digit chip all has address pin and data pin, and the different conditions of address pin (mainly containing high level, low level and unsettled three kinds of states) can be distinguished chip, is used for designing many paired emissions that independently are independent of each other, receives controller.Because the restriction of chip pin quantity, address pin generally adopts 8, and its group/cording quantity has 3 ⁸About kind more than 6400.Though the sign indicating number that can compile is a lot, and is still not enough in some situation, in case occur repeated code especially coded lock will produce serious consequence.Therefore can not adopt general codec in the time of many, can only use single-chip microcomputer to produce more coding, this has limited general codec ground greatly and has used.The function that general general codec does not have cascade to use can't extended coding quantity.Telechiric device with two codec controls can solve the problem that single general codec encodes lazy weight does not have cascade function again, avoids telechiric devices such as coded lock, controller, lamp switch repeated code to occur.

The utility model content:

The purpose of this utility model is to solve because the geocoding quantity of general codec is not enough, causes repeated code, produces the problem of wrong control.Enlarge the application flexibility of general codec chip on the telechiric devices that coded lock, controller, lamp switch etc. need be encoded in a large number.

The technical solution of the utility model is: by two pairs of codec chips are collaborative controlled target is realized control, first pair of codec produces control signal, this signal is as the input of latch, second pair of codec produces latch control signal, and the latch input end is latched into output terminal by the control signal that first pair of scrambler produces.Control procedure can be passed through radiowave, infrared ray etc. and realize wireless remote control.Allow two scramblers successively produce the different coded signal in address at transmitting terminal and give radiating circuit, radiating circuit is successively launched two coded signals.The state of data pin that utilizes the scrambler send signal is earlier passed to receiving circuit and is finished remote control control as control signal.Two demoders of receiving end solve the signal of two address corresponding codes devices respectively, the data-signal of demoder that receives useful signal earlier is as the input of latch, with the reception useful signal of second demoder as the latch control signal, have only two demoders simultaneously effectively, control signal just can be latched device and latch, and realizes control function.Concrete scheme is as follows:

The utility model utilizes two pairs of codecs to control jointly and realizes distant control function.It is made up of transmitter and receiver.Transmitter is by scrambler 1 (1001), scrambler 2 (1002), emission button (1005), radiating circuit (1003), battery (1004) and the control circuit formation is made up of resistance (1006) (1007) (1009) (1010) (1013) electric capacity (1008) (1011) triode (1012).After pressing the emission button, electric capacity (1008) is anodal to produce the signal of high level after the first low level, receives the output enable end of scrambler 1, controlled encoder 1 first outupt coded signal; Triode (1012) collector produces low level signal behind the first high level, receives the output enable end of scrambler 2, controlled encoder 2 back outupt coded signals.The coded signal of scrambler 1 and scrambler 2 outputs is connected to same radiating circuit.

Receiver is made of demoder 1 (1021), demoder 2 (1022), latch (1023), receiving circuit (1024), and the data-signal of demoder 1 is given the input end of latch; The reception useful signal of demoder 2 is received the control end that latchs of latch.After demoder 1 is received correct signal, earlier data-signal is given the input end of latch, when demoder 2 receptions were effective, the control lock storage was latched into output terminal with input signal, and the output terminal of latch connects the circuit that needs control.
