Description
Technical field
The present invention relates to a kind of wireless alarm, especially a kind of can be by code and Digiplex and wireless detector be realized matching used wireless alarm.
Background technology
Wireless doorbell is comprised of the button of wireless transmitting terminals and the bell ringing device of wireless interface receiving end, will launch the radio magnetic wave signal when the button of transmitting terminal is pressed by the people, the receiving end receives, and bell ringing device will send dulect the tinkle of bells, to point out indoor owner, there is outdoors the guest to visit.The electromagnetic wave signal propagation distance of wireless doorbell is far away, need not connect up, and installs simply, so be used widely in places such as residential building, business offices.But, wireless doorbell of the prior art, the ringing volume that can send is all smaller, therefore be only applicable to more quiet place, if in the very large place of noise, such as in the very large factory floor of noise, the tinkle of bells that volume is less is heard by the people in the field with regard to being not easy.
In order to allow people's accurate understanding context, first in this explanation: " loudspeaker " and " loudspeaker " are synonyms, are more colloquial style of " loudspeaker " word.For the ease of accurate expression, here the usage of approving according to most people in the row first, concept to " warning horn " and " alarm " these two nouns is carried out clear and definite defining: " warning horn " refers to and can only operate on one's own initiative the product that control gives the alarm by people, for example people realize controlling the sounding of a siren and stopping sounding by stirring a switch, and this equipment is exactly " warning horn "; " alarm " refers to and can be triggered and the product that automatically gives the alarm by sensor or detector, and for example when gas leakage occured, gas detector can give the alarm automatically, and Here it is " alarm "; If the same product has the function of " warning horn " and " alarm " concurrently, just it is belonged to " alarm " kind.For fear of obscuring the meaning of a word, the above-mentioned definition of conception of adhere rigidly to of the present invention carries out the in full elaboration of content.
The principle of sound of horn type loudspeaker is moving-coil type electroacoustic transfer principles, there is coil the toroidal magnetic field that loudspeaker the insides has permanent magnet to generate in the magnetic field, when audio electrical signal electric current by coil the time, coil vibrates under the effect of magnetic field force, thereby drives the sound film vibration sounding that links to each other with coil.Obvious characteristic on the horn type loudspeaker profile is the opposite sign cylinder that also has a back-off in the middle of the horn, and the sound that loudspeaker send is reflected back by the opposite sign cylinder first, is reflected away by the horn of outside again.The key distinction of horn loudspeaker and cone coil-moving speaker is exactly indirec radiation, i.e. after the vibrating membrane vibration, sound will greatly strengthen sound, and make sound to a direction intent propagation through horn to external diffusion, makes the distance of sound transmission farther.The sound film of horn loudspeaker promotes to be positioned at the air of horn bottom and works, because so the very large efficient of acoustic resistance is very high, again because sound through two secondary reflections of opposite sign cylinder and horn, so horn loudspeaker has high directivity, power is large, efficient is high advantage.
Have a kind of very common warning horn accessory to be named as " 626 warning signal " in the prior art, function is very simple: as long as connect with the mains to it, it will sound the alarm, as long as to its outage, it will stop sounding.The alarm song that 626 warning signals are sent has fright power very much! This alarm song by between the high-low sound frequency repeatedly the sound of gradual change form, sound at people's ear, similar to the voice that the mankind promptly read aloud " 6262 " these several numerals continuously with Chinese, people are as long as repeating consistently to chant " 6262 " these several numerals just can generally simulate this alarm song in other words, and " 626 warning signal " hence obtains one's name.The main body of 626 warning signals be exactly one with the horn type loudspeaker of metal support, there is cavity the horn bulb the inside, in cavity, be fixed with a tetragonal circuit board with screw, it is exactly the audio electrical signal circuit for generating of 626 warning signals, this circuit is by diode, triode, the self-excited oscillation type circuit that resistance and electric capacity form, the lead-in wire of speaker voice coil just is welded on the output terminal of this circuit, article one, red-black twin conductor is welded on the power input of this circuit (red line connects positive pole, black line connects negative pole), the other end of red-black twin conductor extends to the outside by the aperture of horn bulb bottom, as the power input of 626 warning signals.
The operating voltage of 626 warning signals is direct currents of 6V to 12V, so can not directly link to each other it with civil power; The power lead of 626 warning signals is unsettled red-black lines, will notice when linking to each other with direct supply that both positive and negative polarity can not connect instead, and instead it just can not be sounded if the both positive and negative polarity electric wire connects; So 626 warning signals are not a kind of popular products for civilian use, and be a kind of special electronic components, need to be by the people with certain professional knowledge, just can use after being installed in it in the suitable circuit, for example it is connected on the battery of 12V by a switch, the closure by gauge tap is controlled 626 warning signals and is sounded the alarm and stop sounding with disconnecting.
626 warning signals generally are used as warning horn and use, if realize the function of alarm, then need 626 warning signals are connected with special alarm host machine, do meeting like this so that a whole set of products volume greatly, higher, the complex structure of cost, wiring and installation be all cumbersome.For volume and the cost that reduces product, most alarm is the alarming horn of making microphone device with the buzzing sheet in the prior art.The buzzing sheet is a kind of small volume that utilizes piezoceramic material electrostriction principle to make, lower-cost electro-acoustic transducing device,, a large amount of facts has proved that the alarming horn of employing buzzing sheet is shorter serviceable life, because the electrical wire of buzzing sheet is the silver coating that directly is welded in above the piezoceramic material, when sending the alarm song of loud noise, the buzzing sheet is in the state of high vibration, if things go on like this, silver coating above the piezoceramic material crack can occur even part is peeled off, electric wire pad on the buzzing sheet may become flexible even come off gradually, and the audio warning quantitative change that causes loudspeaker to send is little even can not sound.In addition, the buzzing sheet also can be with heating when sending the alarm song of loud noise, the piezoceramic material problem that also life period is aging and temperature is aging, and the electrostrictive property of the piezoceramic material after wearing out can descend.
By contrast, the serviceable life of the alarming horn of employing moving-coil type principle of sound is longer.More existing alarms no longer adopt buzzing sheet loudspeaker as alarming horn in the prior art, but a moving-coil type cone loudspeaker is installed as alarming horn in alarm host machine inside,, the alarm song volume that this cone loudspeaker send is less, can not show a candle to the fright dynamics of the alarm song that 626 warning signals send.
In the prior art, realized utilizing the electromagnetic wave transfer control signal, the binary data of TTL form is modulated at the electromagnetic wave of certain frequency and has launched at transmitting terminal, the data that electromagnetic wave obtained transmitting by demodulation at receiving end.Because electromagnetic wave propagation is distant, mutually crosstalk for fear of the radio signal that different user sends, the geocoding that is used for signal identification or encrypted code and the data code of alternate manner are made up according to certain form together, afterwards, they are modulated on the electromagnetic wave together launch, at receiving end the encrypted code that demodulation obtains is checked according to corresponding form, whether effective to judge received control signal data.At transmitting terminal data code and cognizance code are called " coding " according to the process that certain form makes up, the process of exporting data code after the cognizance code that receiving end obtains demodulation is checked according to certain form is called " decoding ".The below introduces the coding and decoding mode of several radio signals commonly used at present.
The fixed code code encoding/decoding mode, the coding chip PT2262 of transmitting terminal forms a complete code word with address code, numeric data code, synchronous code, being modulated to electromagnetic wave goes out by antenna transmission, receiving end receives electromagnetic wave and obtain character signal after demodulation, deliver to chip PT2272 or single place machine is decoded, after its address code was relatively checked through twice, the VT pin was just exported high level, and meanwhile corresponding data pin is also exported high level.In usually using, we generally adopt 8 bit address codes and 4 bit data codes, at this moment the 1st～8 pin of coding chip PT2262 and decoding chip PT2272 is the address setting pin, there are three kinds of states available: unsettled, connect positive supply, three kinds of states of ground connection, so geocoding does not repeat there are at most 6561 groups.Adopt the product wireless receiving and dispatching of fixed code code encoding/decoding mode distant, permission is unrestricted to the quantity of the transmitter of code or receiver, do not need transmitter and receiver are put together, also can copy transmitter or receiver, all need to be at location, circuit board enterprising pedestrian building site encoding operation at transmitting terminal and receiving end, only have when the geocoding of transmitting terminal and receiving end identically, could match use.
The learning code code encoding/decoding mode is divided into again two kinds of 1,000,000 groups of learning codes and rolling code learning codes.The product of employing learning code code encoding/decoding mode need to be at the enterprising pedestrian worker's encoding operation of circuit board at transmitting terminal and receiving end, so it is very convenient to produce, but the permission of each receiver is restricted the quantity of the transmitter of code, and necessarily require receiver and transmitter to put together, just can finish study to the operation of code.
The transmitting terminal of 1,000,000 groups of learning codes is encoded by the EV1527 chip, but EV1527 is the coding IC of a slice pre-burning ISN, but ISN has 1048576 groups of interior code combinations of 20 bit pre-burnings, reduce the probability of using upper coding to repeat, generally by software decode, also can carry out the hardware decoding with special decoding chip at receiving end.
The rolling learning code generally refers to adopt the coding and decoding mode of the keeloq enciphering and deciphering algorithm of U.S. Microchip company, the code that rolling coding sends each time all is unique, irregular and does not repeat, so all can't crack by means such as any illegal seizure and scan tracings, it is the highest a kind of wireless encoding mode of security, its transmitting terminal is finished coding by chips such as HCS300/301, receiving end is realized decoding by Single Chip Microcomputer (SCM) program usually, also can carry out the hardware decoding with special decoding chip.Adopt the product of rolling learning code code encoding/decoding mode, if improper use makes troubles for user oneself, for example after telepilot and receiver are realized code, if the user presses remote controller key repeatedly in the place that receiver does not receive signal, by arriving certain number of times, will cause receiver not identified this telepilot again, need again to just reusing after the code study.
In sum, three kinds of code encoding/decoding modes have merits and demerits separately, and people can carry out reasonable selection according to the specific requirement of practical application.
The transmitting terminal of radio signal can be Digiplex, also can be the push button transmitter of wireless doorbell, can also be various wireless detectors.Wireless detector refers to various sensors and radio transmitter are combined, product by sensor-triggered radio transmitter transmitted radio signal, wireless door magnetic automatic transmitted radio signal when door is opened for example, Radio infrared probe has detected in the physical activity automatically transmitted radio signal in investigative range, the wireless detector that also has in addition many other kind functions, for example Radio infrared correlation, the Radio infrared curtain, the Radio infrared fence, wireless wire breakage detector, wireless smoke alarm, wireless gas leak detector etc.The various functional accessory of wireless signal transmission end, want elder generation and wireless interface receiving end to carry out the use of could arranging in pairs or groups after the code study, we support the use the wireless transmitting terminals of fixed code or learning code and wireless interface receiving end and consistent address code being set or carrying out study to the operation of code of carrying out in order to realize mutually identifying, and are referred to as " to code ".
On the electronic market a kind of " wireless receiving head " arranged at present, it can receive the also electromagnetic wave of certain frequency of demodulation, through the electric signal that obtains after the demodulation of wireless receiving head, be the character signal that does not also have decoded TTL form, the decoding chip that can send single-chip microcomputer or special use to is decoded.
The coding/decoding method of the electromagnetic wave signal of above-mentioned three kinds of codings can carry out the hardware decoding by corresponding decoding chip respectively.Such as the signal with fixed code coding chip PT2262 coding, can be decoded by decoding chip PT2272; The signal of 1,000,000 groups of learning code coding chip EV1527 codings can be decoded by decoding chip TDH6300; The signal of rolling learning code coding chip HCS301 coding can be decoded by decoding chip NT2185.But can not realize three kinds of different coded signals of decoding with a certain chip, the chip PT2272 signal of learning code coding of can not decoding for example, for another example the chip NT2185 signal that 1,000,000 groups of learning codes are encoded of can not decoding.
The coding/decoding method of the electromagnetic wave signal of above-mentioned three kinds of codings also can carry out software decode by different Single Chip Microcomputer (SCM) program.Single-chip microcomputer can be realized software decode according to corresponding coding rule according to the instruction of program, and obviously, different coded systems should be decoded by different programs, that is to say, can not realize simultaneously decoding to three kinds of different coding modes with a kind of program.
At present in addition a kind of " the wireless receiving circuit module of band decoding " on the electronic market, be called for short " wireless decoding module ", it is manufactured on wireless receiving head reconciliation circuit decoding circuit on the little circuit board of same together, and the data that electromagnetic wave signal obtains after the demodulation code are by the direct row's of exporting to needle interface.Can adopt the hardware decoding also can adopt software decode in the wireless decoding modular circuit, the wireless decoding module that different coded systems is corresponding different, but the data layout of row's pin output interface of various wireless decoding module but all is the same.Row's pin of wireless decoding module generally all is that seven stitch are arranged, two power supply input pins that stitch is modular power source wherein, and other has a stitch is VT signal output pin, four remaining stitch are output pins of D0, D1, these four data bit of D2, D3.
Summary of the invention
Existing three kinds the code encoding/decoding mode having introduced radio signal of the prior art in front has advantage separately, because without any can decode the simultaneously signal of three kinds of different codings of a kind of decoding chip, there is not can decode the simultaneously signal of three kinds of different codings of any software program yet, so, if in alarm host machine, adopt wireless receiving head demodulation electromagnetic wave signal, have at least a kind of telepilot of coded system and wireless detector can't realize with this alarm host machine code in three kinds of coded systems, so just can not take into account the advantage of three kinds of coded systems, this is with the range of application of limits product.
Advantage for three kinds of code encoding/decoding modes taking into account radio signal, the technical solution used in the present invention is: the alarm host machine of receiving end adopt the wireless decoding module to the radio magnetic wave signal receive, the demodulation code, the data that decoding is obtained directly are sent to the I/O mouth of single-chip microcomputer.That is to say, power circuit, single chip machine controlling circuit and drive circuit of loudspeaker are manufactured on the circuit board, here be called it " main circuit board ", the wireless decoding module then is on the little circuit board of another piece, realize electrical connection by metal row pin between two circuit boards, the various functional accessory of wireless transmitting terminals are as long as realize just can supporting the use with product of the present invention afterwards code with the wireless decoding module.Adopt the wireless receiving head that electromagnetic wave is carried out after the demodulation again by the way of single-chip microcomputer decoding in the contrast wireless alarming host, the technical scheme that the present invention adopts the wireless decoding module that radio signal is carried out the demodulation code mainly contains following two beneficial effects: first beneficial effect is the advantage that can realize taking into account three kinds of coded systems of radio signal.Because the output interface of various wireless decoding modules all is the same, so, do not need to change the hardware configuration of main circuit board, do not need to change the Single Chip Microcomputer (SCM) program content yet, as long as change the wireless decoding module, people just can freely select fixed code or 1,000,000 groups of learning codes or rolling learning code as the decoding process of radio signal.Second beneficial effect is that single-chip microcomputer can no longer be carried out heavy decoding task, and this has saved mcu resource to a great extent, is very beneficial for single-chip microcomputer and carries out other program task.As everyone knows, radio signal is after demodulation, and the program of being decoded by single-chip microcomputer is very complex, and Single Chip Microcomputer (SCM) program must constantly be detected input pin and whether occur electric signal to be decoded and need to respond at any time.A large amount of facts is verified, if same single-chip microcomputer will be carried out the decoding task program on one side, also to carry out the task program of other complexity on one side, be easy to occur the conflict that mcu resource utilizes the aspect between the two, in order to reduce conflict as far as possible, need to carry out a large amount of work and whole program is made amendment and optimize, sometimes in addition some function of having to sacrifice product avoid conflict between the two.So the present invention adopts the wireless decoding module to finish the demodulation code task of radio signal, from heavy decoding task, freed by to be allowed single-chip microcomputer, not only simplified Single Chip Microcomputer (SCM) program, and be conducive to improve the performance of Single Chip Microcomputer (SCM) system steady operation, be conducive to product and given play to more function.
As everyone knows, the volume of the cavity of horn type loudspeaker inside is very limited, is difficult to hold too many circuit devcie.In the market 626 warning signals for example, the assembly of the self-maintained circuit of the inside comprises 2 diodes, 9 resistance, 6 electric capacity, 5 triodes, and these 22 components and parts are the plug-in unit encapsulation entirely, whole circuit volume has taken most of volume of 626 warning signal internal cavities, therefore is difficult to existing alarm host machine is put into the cavity of horn type loudspeaker.
In order to realize integrated with wireless alarming host and horn type alarming horn, the present invention at first simplifies drive circuit of loudspeaker.As shown in Figure 2, drive circuit of loudspeaker of the present invention is comprised of R1, R2, Q and D2, only use altogether 4 electronic devices and components, contrast 22 electronic devices and components of the original phonation circuit of 626 warning signals, component number and the circuit cumulative volume of the drive circuit of loudspeaker of the present invention after process is simplified all have reduced several times! Realized moving in the cavity in the horn type loudspeaker and vacateed enough large remaining space, be used for holding the other parts circuit structure of wireless alarming host.
In order to realize integrated with wireless alarming host and horn type alarming horn, the present invention simplifies the circuit structure of wireless alarming host.Wireless alarming host circuit of the present invention comprises these four parts of power circuit, wireless receiving decoding circuit, single chip machine controlling circuit and drive circuit of loudspeaker.Wherein, the major function of power circuit is that the voltage from extraneous direct supply input is obtained 5V voltage through voltage stabilizing IC step-down, provides suitable operating voltage to be embodied as wireless receiving decoding circuit, single chip machine controlling circuit and drive circuit of loudspeaker; The wireless receiving decoding circuit receives the radio magnetic wave signal, after the demodulation code, data-signal is sent to the input pin of single chip machine controlling circuit; Single chip machine controlling circuit is comprised of one chip microcomputer and peripheral circuit thereof, and single-chip microcomputer is carried out corresponding program according to the data content of input pin, and at output pin output audio electric signal to drive circuit of loudspeaker; Drive circuit of loudspeaker is responsible for amplifying the audio electrical signal from single-chip microcomputer, drives the horn type sound horn.
The present invention adopts the three ends pottery crystal oscillator of 4MHz to carry out frequency stabilization in single chip machine controlling circuit.Because when wireless receiving module cooperates single-chip microcomputer to use, if the frequency of single-chip microcomputer crystal oscillator is too high, the higher hamonic wave of crystal can obviously be disturbed the work of wireless receiving module, so that wireless communication distance reduces, therefore, the present invention selects the 4MHz crystal oscillator of lower frequency value, is conducive to increase wireless communication distance.Three ends pottery crystal oscillator all has been integrated in load capacitance the inside of crystal oscillator, the circuit structure of necessary external two load capacitances of contrast two ends quartz crystal oscillator, clearly, the microcontroller system circuit structure of employing three ends pottery crystal oscillator of the present invention is simpler, the circuit cumulative volume is less.
Fact proved, the wireless alarming host circuit is through after the above-mentioned simplification, can realize whole wireless alarming host circuit is successfully put into the cavity of 626 warning signals, with screw circuit board is locked inside again, only link to each other with the direct supply in the external world by a power lead.
Pass through mcu programming, and by realizing code with two key Digiplexs and wireless detector, product of the present invention can be realized the function of wireless remote control alarm, two buttons of telepilot are respectively as the function of key with the key of withdrawing a garrison of deploying troops on garrison duty, if press the key of withdrawing a garrison, product of the present invention sends the prompt tone of withdrawing a garrison, then enter disarming state, although at this moment receive the radio signal of wireless detector emission, product of the present invention does not sound the alarm yet, if press the key of deploying troops on garrison duty, product of the present invention sends the prompt tone of deploying troops on garrison duty, and then enters the state of deploying troops on garrison duty, at this moment in case receive the radio signal of wireless detector emission, product of the present invention just sends the alarm song that fright power is arranged very much, at this moment, presses the key of withdrawing a garrison and can stop sounding and enter disarming state.
Cone formula moving-coil loudspeaker against existing technologies, the present invention selects the horn type loudspeaker as electro-acoustic transducing device, can send the alarm song that fright power is more arranged, the operation indicating sound that can send larger volume.Piezoelectric ceramics buzzing sheet loudspeaker against existing technologies, the present invention selects the horn type loudspeaker as electro-acoustic transducing device, the longer service life of loudspeaker.
The product structure that separates of middle alarm host machine and alarming horn against existing technologies, the present invention's beneficial effect that the realization of wireless alarming host and alarming horn is integrated is: the structure of a whole set of products is simpler, cumulative volume is less, total cost is lower, install and wiring all more convenient.
Wireless alarm of the present invention only links to each other with the direct supply in the external world by a power lead, and again without other wiring, as seen its mode of connection is very simple in addition.This power lead can be a red-black twin conductor, also can be the DC line of a band female.If adopt red-black twin conductor as the power lead of product of the present invention, just can be connected to it easily and realize power supply on the 12V accumulator, because the accumulator of 12V is arranged on present most motorcycle and the automobile, so can be installed in motorcycle and the enterprising enforcement usefulness of automobile to product of the present invention.If adopt female DC line as the power lead of product of the present invention, allow that end of female be in the outside of horn bulb, patch mutually with the male output terminal of the power supply adaptor of 12V, power supply adaptor is inserted on the commercial power socket to realize by mains-supplied.Connect positive source because the electrode of the centre of DC male and DC female all is acquiescence, so the user needs only the DC female end that the DC male end of power supply adaptor is inserted into the product power lead, the situation of reverse polarity connection can not occur, simple to operate and easy.
Pass through mcu programming, product of the present invention can send the prompt tone that powers on, namely when giving product plugged of the present invention, product can send a prompt tone automatically, if electric power polarity connects instead, product just can not send prompt tone, realizes whether the power supply access way of product is correctly pointed out.
For the ease of expressing, for example use hereinafter that " D3D2D1D0=1010B " such formula represents that the content of " D3, D2, D1, D0 " these four data bit is respectively " 1,0,1,0 ", the numerical value of the letter in the formula " B " expression front is binary format.The wireless decoding module has 4 data output pins, and 16 kinds of data array modes can be arranged at most, and we can make an appointment respectively which data to make up to represent which kind of control signal with in advance.Can represent the doorbell signal with D3D2D1D0=0001B such as us, the data bit of doorbell button is arranged to D3D2D1D0=0001B, when the data that receive when single-chip microcomputer are combined as D3D2D1D0=0001B, just allow the Single-chip Controlling loudspeaker send doorbell sound, the data that we can also arrange other make up the Radio Control Function of realizing respectively other.
By mcu programming, and by realizing to code that with the push button wireless launcher product of the present invention can be used as super large volume wireless doorbell and uses, whenever by a button, product of the present invention is just play the doorbell sound of a super large volume: " ding-dong ".The ringing volume of middle wireless doorbell is too little thereby be not suitable for using in the very large place of noise against existing technologies, and the horn type loudspeaker of product of the present invention can play out the doorbell sound of volume super large, therefore can adapt in the very large place of noise to use.
Pass through mcu programming, and by realizing code with two key Digiplexs, product of the present invention can be used as radio remote-control alarm and uses, two buttons of telepilot are respectively as the function of alarm keys and stop alarm key, if push for emergency key, product of the present invention just sends the alarm song that fright power is arranged very much; If press the stop alarm key, product of the present invention just stops sounding.626 warning signals will be controlled by wired switch and sound the alarm and stop sounding against existing technologies, and product of the present invention can realize that the long-distance remote control operation sounds the alarm and stops sounding, controls more flexible, more convenient by Digiplex.
