On above-mentioned disclosed wireless camera basis, present invention also provides the wireless camera system comprising above-mentioned wireless camera, this wireless camera system is except comprising above-mentioned wireless camera, also comprise external expansion module, external expansion module comprises the second processor, and the operating member be electrically connected with the control end of the second processor;
Wired input of the second processor is electrically connected with data output pins;
The line output terminal that has of the second processor is electrically connected with data-out pin.
The second processor namely in external expansion module is connected by the data output pins in data line interface 103 and data-out pin with the first processor 102 in wireless camera.In fact, can be understood as data output pins and data-out pin constitutes a digital serial port, first processor 102 and the second processor carry out data interaction by these two pins.That is, wireless camera can assign signal (comprising data and instruction) by these two pins to external expansion module, also can receive by these two pins the signal that external expansion module uploads.
The control end of the second processor is electrically connected with operating member, thus the second processor can pass through control end (can be understood as a pin of the chip of the second processor) assigns action command to operate portions.Common operating member has: transducer (as infrared sensor, temperature sensor, humidity sensor, barometric pressure sensor etc. can carry out the device of signals collecting, reception), sender unit (as remote controller, voice guard, visual alarm etc. outwardly can send the device of signal), motor are (as synchronous machine, asynchronous machine, mechanical system etc. can carry out space displacement, or the device of deformation.)
Second processor is after the instruction (action command) being received first processor 102 by data output pins, just can according to the mode preset to the instruction of operating member sending action, work is carried out to make operating member, the working method of transducer for gathering environmental information, and generates corresponding digital/analog signal; The working method of motor is for carrying out Power output, and common motor has The Cloud Terrace, bogie etc.
Wherein, first processor 102 has two kinds of sources to the instruction that the second processor sends, and the first is the inner directly generation of first processor 102, and the second is that peripheral control unit generated.
The first situation, first processor 102 inside can pre-set corresponding timing circuit and signal generating circuit, when timing circuit time of adding up reach default requirement time, just control signal generative circuit generates corresponding instruction (action command in control action portion).
The second situation, the wireless communication module 101 be electrically connected with first processor 102 can receive wireless signal, therefore, can be that the peripheral control unit that is separated with wireless camera is to generate action command, and by the mode of wireless transmission, this action command is sent to wireless communication module 101, and then this action command is sent to first processor 102.Then, this actuating signal is sent to the second processor by data line interface 103 by first processor 102 again.Peripheral control unit generates the process of actuating signal and scheme, belongs to that those skilled in the art can directly determine according to concrete condition, does not repeat them here.In the second situation, first processor 102 is when carrying out control signal transmission, can be adopt the mode of transparent transmission to transmit, also can be decrypted the control signal received by wireless communication module 101, after the operation such as demodulation, be transferred to the second processor.

When operating member is sender unit, working result then refers to sender unit, and whether success outwardly sends signal.As sender unit outwardly send signal time, signal will inevitably be generated by similar structures such as antenna or signal generation units, whether work (powering on) by detecting these structures, just can determine whether sender unit works.When detecting that sender unit works, generating by feedback unit inside signal of having finished the work accordingly and (as feedback unit generates high level signal, then can illustrate that sender unit is finished the work).
When operating member is motor, motor operationally needs the output carrying out power, now, has three kinds of modes generating feedback signal.
The first, the actual act that operating member carries out, needs to export high level signal by the designated pin of the chip of instruction issuing unit, triggers.Therefore, this designated pin can be detected and whether output high level signal (working result), judge whether to generate feedback signal, as this designated pin outputs high level signal, then generate corresponding feedback signal, otherwise, quite different.
The second, operating member, can by halted state after the control signal receiving instruction issuing unit, or resting state changes power-up state into, whether powering on by detecting operating member, just can determine whether operating member works, and then determine whether to generate feedback signal.That is, operating member comprises horizontal stage electric machine, and feedback unit comprises the second feedback circuit; Second feedback circuit, for detecting the power-up state of horizontal stage electric machine, and generates corresponding feedback signal.
The third, motor, after carrying out action, can make corresponding physical structure be subjected to displacement, and can rotate or stretch as The Cloud Terrace.So, just the transducer that displacement transducer, contactor etc. can detect physical deformation or spatial variations can be set around The Cloud Terrace, to be moved or after deformation (stretching) at The Cloud Terrace, just can be detected by displacement transducer, then, displacement transducer just can generate corresponding detection signal, this detection signal just can react the working result of The Cloud Terrace (operating member) intuitively, and namely feedback unit generates feedback signal according to this detection signal (working result).
