Description of the Invention: [Technical Field] The present invention relates to a device, and a device for transmitting and transmitting signals using a conductive housing. [Prior Art] Rigang's bicycle industry has become a hot industry because of the energy crisis and healthy winds. Therefore, all kinds of materials were measured and sent out, and the accessories around them also became the target of various manufacturers. However, the safety of bicycles has become an inevitable demand after the replacement of vehicles. In order to increase the safety of bicycles, various extras have been gradually developed. For example, the Republic of China new patent No. M328996 "vehicle warning system", which uses Zigbee technology, is used on the bicycle warning system to facilitate the women's wear of the warning system. The disadvantage is that the Zigbee device is expensive and not easily accepted by consumers. The simplest warning system is to use the traditional transmission line to control the warning signal, but the wired transmission will increase the complexity of the bicycle. For the architecture of the entire communication system, please refer to FIG. 1. The communication architecture 10 includes: a signal transmitting device 2Q, a local oscillator 30, an if channel 40, and a subtraction "50". In the communication system, when the input data 丨np is converted into an analog wave signal, the input signal must first be transmitted through the signal transmitting device 2 to generate a radio wave transmitting signal 传送 and transmitted to the communication channel 40. The communication channel 40 is a medium between the transmitting end and the receiving end, and the general communication channel has a wired channel or a wireless channel. And the transmission signal passing through the communication channel 40 is distorted due to the interference of the channel. When the signal receiving device captures the distorted reception signal VR, the signal receiving device performs decoding and decoding when 201233074. If it is in the bicycle, for example: It is a thin cable or series • transmission to receiving mode, the signal is transmitted through the transmission line or air, so that the transmitting end transmits the data, and the end. However, the signal is the most common: analogy and digital In the two categories, if the modulation method is analogous, it can be classified into three characteristics: amplitude, frequency and phase, which can be modulated by amplitude modulation AM, frequency modulation FM and phase modulation Μ. The analog modulation has a local enchant, the local sigma is also a carrier signal, and the carrier signal is modulated according to an input_input signal. If the amplitude is modulated by AM, the carrier 峨 will be based on the signal. f, phase _ fresh FM 变 峨 峨 frequency, and phase modulation PM is to change the phase of the carrier signal. If the signal is continuous, such as the analog signal that converts the sound into The modulation method will be the __ modulation method of the previous two major themes. If the signal is digital, that is, the binary (four) f material of _, such as 11G111 feeding, the modulation method will be different from the analogy. The following is a description of the modulation of some digital signals. Please refer to the ASK, FSK and pSK waveforms in the 2nd ® ®. In the figure, the PCM is the input binary data 110111 to the modulated emission. (1) On/Off key (OOK for short) The key corresponds to 0 corresponding to cos' 1 corresponding to Acos (2Tifct), where a is a preset amplitude ' cos (2π/^) is a cosine function, and fc is a carrier Therefore, the transmitter only needs one oscillator and one switch gate. (2) Frequency Shift Key (FSK) The two-bit frequency shift key corresponds to 0 to Acos (2π&), and 1 corresponds to Acos (2π (strict c 201233074 +△0 t) ' Af is the interval of the segment frequency. Different receiving modes and the bandwidth of the signal will affect the minimum frequency interval of reliable transmission. (3) Phase Shit Key (psk for short) The two-bit phase shift key corresponds to Asin (2Trfct + e), Corresponding to Asin (2π〇-θ)' where sin(2TTfet) is a sine function, θ is a preset phase. When θ is 90 and 270, there will be the lowest error rate, also called the biphasic shift key. However, the warning system or electronic device on the bicycle is not standard as a motorcycle. However, the problem of using the wireless method in the past is the problem of power consumption, for example, the warning on the bicycle. It is a 剌 battery, and the battery has a certain use efficiency. If the _ square wire design signal Wei device is used, the battery on the service device will consume a lot of power, and the warning system and device on the bicycle often need to replace the battery. The inconvenience caused by the user and the fact that the county is a lion wireless, will also cause the price to be too expensive, and thus less popular. Therefore, how to develop a signal transmitter that is low in cost and low in power consumption will be the direction in which the warning system or electronic device on the bicycle is working. SUMMARY OF THE INVENTION In view of the above problems of the prior art, the present invention provides a signal transmitting device of a kind of transporting body to transmit electric waves, and the modulation of the signal adopts a modulation method of 〇〇κ or FM to achieve utilization. The conductive housing performs the purpose of 〇〇κ or FM signal transmission in real time. The object of the present invention is to provide a kind of city launching device, and (4) the hybrid wireless relaying device must consume a large amount of power. The present invention can save the power consumption of the signal. Another object of the present invention is to provide a 〇〇 调 调 , , , , , , , , , , , , , , , , , , , , , , 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 The principle of the present invention is to convert a plurality of square waves into a plurality of sinusoidal electric housings, and the coupling unit transmits signals to the guide. _ change, the carrier frequency of the unit cell paste generation unit is modulated to the input data, and the input body material is converted into FM data. The above and other objects, features and advantages of the present invention will become more apparent and understood. It is possible to develop a low-cost, low-power-consumption signal transmitting device that can be used as a signal transmission medium for a signal-emitting housing. Take bicycle as an example: launching a job (4) launching a money wave _ launch city, can be applied to bicycle red with conductive components. However, in addition to self-feeding, for other conductive shells with conductive components, the present invention can also be used as a transmission line, such as ED lamps, 匕印路# lamps, locomotives, automobiles, household appliances, etc., having a conductive housing. The components of the invention can be used to achieve wireless applications. In other words, the present invention can utilize a conductive housing to make it a "wire"" thus making the invention a special technique for non-wireless and non-wireless transmission. Thus, the conductive housing can also contain any metal Ingredients, such as gold, silver, copper, etc., and conductive shells with carbon fiber components can also be applied. Commonly used digital modulation systems are modulation methods such as 〇〇Κ, FSK, PSK, etc., in order to reduce power consumption, The 〇〇κ modulation method will make the power consumption of the signal transmitting device have lower power consumption than other modulation devices. Since the modulation mode of the ΟΟΚ is to transmit the 201233074 signal to 1, the modulation It is adjusted to be a plurality of sine waves, and when the transmission signal is 〇, the modulation is to transmit 0 signals without transmitting any signals, and the details of the power of the new office are used. The signal transmitting and receiving system 200' using the conductive housing for transmission includes: a signal transmitting device 1 and a signal receiving device 32. The signal transmitting device 1' of the present invention includes: a frequency generating list 12〇, modulation unit 110, transmitting unit 130 and forgoing unit 180. Frequency generating unit 12〇 is used to generate an operating frequency. Modulation unit 110′ is connected to frequency generating unit it 120 for receiving input data, and A switching frequency is performed on the input data by using a jade frequency to generate a modulation signal. The transmitting unit is connected to the modulation unit 110 for receiving the modulation signal and performing resonance amplification to generate a transmission signal. The signal transmitting device 200 The surface unit 18Q consumes the modulation unit 110 for loading the transmission signal to the conductive housing 210. The conductive housing 21 can be a self-conducting housing, and can also have a conductive shell for automobiles, household appliances, and the like. The device of the body 210. The conductive shell of the towel can also contain any metal component, such as gold, silver, copper, etc., and the conductive shell with carbon fiber component can also be applied, and can also be a general power cord. The signal receiving device 320 includes a coupling unit 310, a spectral unit 320, and a demodulation unit 330. The coupling unit 310 in the signal receiving device 320 transmits the signal from the signal transmitting device 100. The resonant unit 320 receives the consuming unit 310. The transmitting signal is transmitted to the resonant unit 320 through the light combining unit 310. At this time, the resonant unit 320 performs resonance filtering to generate a resonant signal and transmits the signal to the resonant unit 320. The demodulation unit 33 performs demodulation to generate an output data. Next, please refer to FIG. 4, which illustrates a waveform diagram of the entire signal transmission of the OOK modulation method of the present invention. First, the modulation in FIG. The input data inpdata received by the unit 110, the round 201233074 input data inpdata is - the number of consecutive binary sequences, for example: the number of binary sequences of h. When the modulation single 7L 11〇 receives the input data _ata, the fresh generation unit 12调Connecting the modulation unit το 11〇, the modulating unit 110 performs signal modulation on the input > material inpdata according to the frequency signal generated by the frequency generating unit 12 产生 to generate the modulation signal M. According to the concept of the communication system, the number of the sequence of the 1〇11彳 binary is the baseband data, and the frequency generation unit 12〇 produces the phase domain, when the fine data is related to the wave Fresh, the modulation signal 产生 is generated, please refer to the modulation signal μ in Figure 4. • The frequency generating unit 12 can use a capacitive oscillator (LC oscillator), a voltage controlled oscillator (VC0), a crystal, etc., and the modulation frequency range of 00K can be 4〇k to 15MHz. Then, the modulated signal Μ is transmitted to the transmitting unit 130 for resonance signal amplification to generate a transmission signal. The transmitting unit 130 is a spectral circuit. When the modulated signal is input to a square wave signal, the resonant circuit generates a sinusoidal signal. That is, when the modulation signal is multi-wave signal, the resonant circuit generates a plurality of sinusoidal signals. Then, the transmitted signal is transmitted to the light-weight unit in an electric wave mode. Wherein, the surface unit 18〇 forms a capacitive coupling body with the conductive housing 21〇, and the transmitting signal is electrically connected to the single unit; 18〇, and the engaging single S 310 transmitted to the receiving end via the conductive housing 21〇 is received. Signal VR. At this time, the reception signal VR received by the resonance unit 320 in the signal receiving device 3A. The receiving signal VR received by the resonant unit 32 is received by the resonant principle and is received as a resonant signal R. The so-called resonant principle is also a band pass filter. Only when the received signal VR belongs to the frequency band of the filter, the resonant unit 320 In order to receive this received signal VR. Demodulation unit 330 will then demodulate the resonant signal R to restore the input data. Finally, the output data outdata output is the input data_ata. Among them, 201233074 is attenuated due to the launching of the conductive housing 21Q and external noise is fed into the conductive housing. Therefore, the touch unit of the receiving device 3Q0 must have a better bandpass filter, and the spokes from the transmitting unit 31G are filtered to remove the secret noise. Among them, the light junction can be only one capacitor or a plurality of capacitors, and the formation of the light capacitor can be a single piece of metal as the surface of the capacitor, and the conductive housing of the conductive housing 21Q is electrically The other side of the valley is reached. That is, the splicing capacitor can be a single piece of metal and then coated with an insulating layer. When it contacts the conductive housing 21, a capacitance is formed. This capacitor can be considered light. Taking the bicycle as an example, if it is to be mounted on the handle, the aforementioned single piece of metal piece can be made into a ring-shaped hetero structure, which is placed on the metal body of the handle. The towel insulation layer can also be the body paint of the self-driving car shell, and the medium that is added to the vehicle and thinly transferred. Next, please refer to FIG. 5, which illustrates a functional block diagram of the transmitting unit 13A of the present invention. The firing unit 130 includes a first buffer 14A, a second buffer 15A, a resonator 144, and a resonant inductor 142.

The first buffer 140 and the second buffer 15 are combined into a push-pull amplifier. The push-pull amplifier can remove the current from the first buffer 140 to the second buffer 150. Becomes high. After the square wave signal is sent to the transmitting unit 13, the first buffer 14 is positive voltage Vb1, and the second buffer 150 is negative voltage Vb2, so that the current flowing from the positive voltage to the negative voltage is lower than the positive voltage. The rolling structure is doubled more than 'to boost the driving force of the current. Next, please refer to Fig. 6, which is a view showing the operation of the resonant circuit of the transmitting unit 13A of the present invention. Wherein, the resistance resistance Rth of the equivalent resistance is obtained by the line resistance, and the resonant inductor 142 has an inductance resistance value XL, and the resonance capacitor 144 has a capacitance blocking value Xc. Therefore, the circuit's total impedance Z and other scale resistance plus resonance Wei n 142, plus #振 capacitor 144. Since the inductance impedance value χι_ has a phase difference, if the current is used as a reference, it means that the voltage leads the current by 90 degrees, so multiply the sign of positive j, the same capacitance impedance value xc also has a phase difference, if based on current 'It represents the voltage backward current 9 相 phase angle, so multiply the negative sign, the total impedance of the circuit Z = Rth + jXL_jXC. Among them, forbearance = 211 where, f is the frequency of the input square wave, and L is the inductance value, and - is 疋, and f is also the frequency of the input square wave, and c is the capacitance value. Furthermore, when the circuit conforms to the It vibration circuit, it represents XL equal to xc, so z will be equal to 灿, at this time, the 'first buffer 140 is a positive voltage Vb1, and the second buffer 15 〇 is a negative voltage, wherein the positive voltage Vb1 is the same size as the negative voltage and the voltage is reduced. Its equivalent dependence Vth is equal to the positive voltage Vbi minus the negative voltage Vb2 such that vth = 2Vb1. At this time, the equivalent current rib 201233074 is the equivalent voltage Vth divided by Rth, that is, the formula is |th=vth/z will get the maximum current. And since the circuit is a resonant circuit, the output end of the transmitting unit 130 is measured to measure the sine wave of the positive half-cycle of the transmitting signal parent output, and when the current is stopped, the negative half-cycle sine wave is generated' so when the square wave signal is input once To the transmitting unit 130, the transmitting signal output by the transmitting unit 130 generates a complete sine wave, and when a plurality of square wave signals are input, a plurality of sine waves are generated. Wherein, the size of the transmitted signal 量 measured by the output of the transmitting unit it 130 is related to the quality factor of the circuit. The definition of the number of quality a is related to the prior art of the person of the circuit. The details are not described herein. Therefore, the voltage v at the two ends of the resonant capacitor _ 144 is equal to the quality factor _ multiplied by the equivalent voltage (Vc = Q * Vth). That is, the voltage at the end of the capacitor 144 __ is the end point of the ground unit ′, that is, the output end of the transmitting unit 130, and the generated signal size is also the size of the transmitting signal X. As can be seen from the figure in Fig. 4, when the modulated square wave signal is input to the transmitting unit 130, the output of the transmitting unit 13A is measured by the output end of the transmitting unit 13A. The signal X is transmitted to know that the signal is amplified. This - the transmitted signal is a sinusoidal wave having radio properties. The sinusoidal wave of the electrical f can be electrically charged via the shank unit. Pro, #Drive the load, 传递 transmit the conductive housing through the light combining unit 18Q. Next, the meaning of the resonant frequency and bandwidth of the present invention will be explained below, in which the spectral frequency 2rWI?'? represents the inductance of the resonant inductor 142, and C represents the capacitance of the f-inductor 142. The bandwidth of the emission _ 13 本 of the present invention is equal to the resonance frequency divided by the quality factor (2)' and the carrier frequency of the transmitted signal is 00κ in the present invention. The carrier frequency is between 2 and 15 _, that is, the carrier The frequency does not exceed the frequency of the spectral frequency. Where ',, £ 12 201233074 The carrier frequency is based on the operating frequency generated by the frequency generating unit 120, that is, the operation is rarely between 40 kHz and 500 kHz. Furthermore, the architecture of the present invention can also be applied to FM modulation systems. Next, please refer to Figure 7 to illustrate the entire transmission of the 观 剌 FM 方式 _ _ _ _ _ _ _ _ _ First, the input data in Fig. 7 is input to the modulation unit 11A, and the input data j is stunned into a continuous number of carry-orders, for example, the number of binary sequences of 110111. After the modulation unit 11Q receives the input data inpdata, the frequency generating unit 120 is connected to the modulation unit 11〇, and the modulation unit 11 refers to the frequency signal generated by the frequency generating unit 120, and performs signal modulation on the input data inpdata to generate a tone. Change signal Μ. In the FM _ change system, the FM modulation method is used to transmit the carrier wave of f1 when transmitting the data, and the carrier wave is transmitted when the data is transmitted, and the frequency generating unit 120 is also transmitted. To adjust different carrier frequencies. The frequency generating unit 120 can adopt a voltage control vibrator (v〇itage contr〇||ed 〇scj丨丨at〇r, referred to as VCO), a crystal (crystal), etc. The frequency of the applied FM can be adjusted to 4 〇〇k to 15mhz. Then, the modulated signal Μ is transmitted to the transmitting unit 13 for resonance signal amplification to generate a transmission signal. The towel, the sending element 130 is a resonant circuit, and when the modulated signal is input to a different square wave, the weaving circuit also generates a different thief number. That is, when the modulation signal Μ is a different square wave reduction, the weaving circuit will generate different thief numbers. Then, the transmission signal is transmitted in a radio wave manner to the unit. The splicing unit 18Q and the conductive housing 210 form a capacitive occlusion body, and the transmitting signal is multiplexed with the single unit 18Q in a radio wave manner, and the light combining unit 31Q transmitted to the receiving end via the conductive housing 21Q is the receiving signal VR. At this time, the reception signal VR received by the signal receiving device 3QQ frame unit 320 is received. The resonant unit 320 receives the received signal VR received by 201233074, and uses the resonance principle to receive it into the resonant signal R. The so-called resonant principle is also a band pass filter, only when the received signal VR belongs to the frequency band of the filter, and the resonance Unit 320 can receive this received signal VR. Demodulation unit 330 will then perform FM demodulation on the resonant signal R to restore the input data. Finally, the output data 〇utdata output is the input data inpdata. Wherein, since the transmission signal passing through the conductive housing 210 is attenuated and external noise is fed into the conductive housing. Therefore, the resonance unit 32 of the signal receiving device 3〇〇t must set a better bandpass filter H' to remove unnecessary noise from the transmitted signal transmitted from the unit 31Q. Therefore, the use of this hair _ can be used to send a signal transmitter with low price and low power consumption. In order to make the signal transmission reach a very low power consumption, the modulation method utilized by the present invention adopts the OOK/FM modulation method. If the 〇〇κ modulation method is adopted, the data transmission is only transmitted when the data is transmitted. Radio waves, when transmitting data, do not transmit radio waves. In the FM modulation mode, when 1 data is transmitted, the carrier wave of f1 is transmitted, and when the Qf material is transmitted, the carrier wave of f2 is transmitted. Therefore, in order to achieve a q〇k or FM_variation mode, the present invention designs a transmitting circuit in the transmitting unit 130 in a series of harmonics (4) of _R, L, and c. Therefore, in the present invention, it is true that the cost of the Zhao device is reduced. Although the present invention is well-prepared for implementation, the above-mentioned work, green and _ earning the invention, any skilled person, the spirit and details of the invention, can make some changes and Lin, so this turn Cong Shi is determined by the scope of the patent (the fourth) patent scope.
