Embodiment
As shown in Figure 1, sensor U102 gathers temperature in the kettle, reaches after the temperature value of setting the power supply of sensor conducts wireless transmit coding chip U101 when temperature.After coding chip U101 starts working, at first read the setting value of A0～A7, encoded in the address, again address code and numeric data code are exported from 17 pin.After coded signal arrives Q103, after the Q103 modulation, export from antenna.Y101 is the surperficial frequency stabilization device of sound among the figure, and its effect is that the output signal with coding chip U101 modulates the signal to 315M by Q103.The vibration frequency selection circuit that L101 and C102 form, its effect are that the signal that will modulate carries out frequency-selecting amplification output.Adjust the scale value of L101 and C102, the centre frequency of frequency-selecting can be adjusted to 315M, thereby determine transmission frequency.As shown in Figure 1, promptly (A0～A7) can be short-circuited to high level, low level and floating empty respectively, the address that the combination of three kinds of such states can unique definite U101 has 6561 kinds of different geocodings to 1～8 pin of U101.17 pin of U101 are the signal output pin, are connected to by R103 on the base stage of Q103 to modulate.R101 is an oscillation resistance, can determine the code rate of U101 by the resistance of adjusting R101.Y101 is a 315M sound table device, and the one end is directly connected to the Q103 base stage, and the other end is connected to the collector of Q103 by an inductance, and its effect is to modulate the signal to 315M.Q103 is a high-frequency tube, and its effect is that the signal modulation is amplified.To ground, its signal outputs to antenna from collector output by a capacitor C 101 to the emitter-base bandgap grading of Q103 by a resistance.
After signal sends from radiating circuit, receive by receiving circuit shown in Figure 2.Signal is after the antenna input, tuning amplification circuit frequency-selecting through C2 and L1 composition, the vibration frequency selection circuit effect that C2 and L1 constituted is filtering, antenna can receive the radiowave of various frequencies, but we only need frequency is the wireless signal of 315M, by the wave filter that L1 and C2 formed, the undesired signal filtering can be amplified useful signal.The effect of Q1 is that wave filter output is amplified.Devices such as Q2 and L2, C6, C7 are formed the superregeneration high frequency receiving circuit, adjust the sense value of L2, make its centre frequency consistent with transmission frequency.The radiowave that is received by antenna carries out tuning pre-amplification through L1, C2, Q1, go out modulation signal by the preposition amplification post-detection of Q2 again, output to and further amplify after the shaping the identical coded signal of exporting by U101 among the 1 pin output of IC1 and Fig. 1 among the IC1.As shown in the figure, C3 is a capacitance, and effect is the filtering dc noise, and C3 one terminates on L1 and C2 and the antenna, and the other end is received on the base stage of Q1.The emitter-base bandgap grading direct short-circuit of Q1 is to ground, and collector is linked C4 and upward its amplifying signal exported by C4.IC1 is a slice binary channels operational amplifier, and wherein 5,6 pin, 7 pin are one group of operational amplifier, and 1,2,3 pin are one group of amplifier.Amplify later signal through Q1, Q2 detection, link to each other with 5 pin of IC1 by C10, signal is by the 5 pin input of IC1, and 6 pin of IC1 arrive ground by R14, and are connected to 7 pin by R15.Signal by the output of 7 pin, is connected with 3 pin by C12 after first group of amplifier of IC1 amplifies, and signal is sent to shaping in the second level amplifier of IC1.Thereby make the identical coded signal of 17 pin of U101 from the output of 1 pin of IC1 and Fig. 1.
As shown in Figure 3, U204 is a demoder, and its effect is, the coded signal of IC1 output among Fig. 2 is decoded.1～8 pin of U204 can be shorted to power supply or ground also can float sky, thereby three kinds of states are arranged, the address that the mutual combination of these three kinds of states can unique definite U204.In the emission process of wireless signal, we are undertaken geocoding to each sensor by A0～A7 pin of setting U101.So in the process of decoding, we will set the address identical with U101 to the A0 of U204～A7.When the address of demoder U204 was identical with the address of scrambler U101, U204 just can export effective decoded signal, thereby has avoided interference.As shown in Figure 3,14 pin of U204 are connected with the 1 pin output of IC1 among Fig. 2, and what 1 pin of IC1 was exported is coded signal, will decode after U204 receives coded signal, and compare with the address of setting.Will be when if the address of decoding is consistent with the address of setting from single pulse signal of 17 pin output.This single pulse signal drives relay K 201 by Q5.The control signal of K201 connects the collector of the triode Q205 of 12V power supply and its conducting of control respectively.17 pin of U204 are connected to the base stage of Q205 by a resistance R 204.When 17 of U204 exports high level, the Q205 conducting, collector and emitter are similar to short circuit, thus conducting K201.After K201 starts working, connect flash lamp circuit.As shown in the figure, after K201 connects the flashlamp operating circuit, after the 220V alternating current process D207 rectification, capacitor C204 is charged, after charging finished, the voltage difference at neon tube N201 two ends reached ratings conducting later on, thus the control utmost point conducting controllable silicon of control controllable silicon Q207.Controllable silicon Q207 conducting, capacitor C 204 begin discharge, because the capacitor discharge electric current produces the instantaneous voltage up to thousands of volts through transformer L205, and this high voltage meeting conducting flashlamp L206 discharge, thus realize luminous function.Along with the C204 discharge finishes, controllable silicon Q207 ends, and restarts the flash of light to a C204 charging beginning new round.As shown in Figure 3, capacitor C 201 is formed the resistance-capacitance depressurization circuit with resistance R 201, to the step-down of 220V alternating current, after D1～D4 rectification, circuit is provided the supply voltage of 5V and 12V by stabilivolt D206 and D208 again.As shown in Figure 3, the C204 two ends connect the primary coil of neon tube N201 and transformer L205 respectively.The secondary coil of L205 is connected with the control utmost point of the L207 of speedlight.The two ends of R209 are in parallel with C205, and effect is for the charge discharge that stores among the C205 after circuit quits work.R207 is by the control utmost point and the anode of neon tube N201 connection controllable silicon Q207, and R206 connects the silicon controlled control utmost point and negative electrode respectively.
Because the perceived ability of light signal will be eager to excel more than voice signal, and before flashlamp, add coloured light signal that the filter of different colours can make flashlamp send, for example red, more eye-catching, thus better play the effect of prompting.If, amblyopia colony hard of hearing for some, sound or light signal can up to suggesting effect will weaken, but by a portable Vib. to the user provide can be perceived vibration signal, thereby solved this problem.
