The utility model compared with the prior art, has conspicuous advantage, adopt eight special-purpose microcomputer chips of the FT001 of Feixiang Kitchen Equipment Co., Ltd., Ningbo, the fuzzy logic control technology, electrical characteristic to gas-sensitive head detects automatically, in use revise according to the gas-sensitive head characteristic, and corresponding definite suitable numerical value (alarm point).If gas-sensitive head lost efficacy or damaged, can send sound and light alarm signal prompt user, and cut off automatic transmission, after the detection gas-sensitive head is normal, can use.The user can change gas-sensitive head voluntarily, need not to carry out any adjustment.Owing to adopt fuzzy logic control technology, fundamentally stopped to be subject to the influence of environment temperature and humidity variation, improved the Performance And Reliability of controller greatly.The utility model also has prompt facilities such as regularly reminding timing shutdown and multiple acousto-optic news sound.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the circuit theory diagrams of a preferred embodiment of the utility model;
Fig. 2 is that the circuit of a preferred embodiment of the utility model is formed the relation principle block diagram.
See also illustrated in figures 1 and 2, the utility model is formed the body (not shown) by housing, blower fan M and keyboard 7, housing is provided with a controller, this controller rings circuit 3, display driver circuit 4, controlable electric current 5 and microcomputer chip 6 by power circuit 1, testing circuit 2, news and connects to form through lead, power circuit exports testing circuit respectively to, news are rung circuit, display driver circuit and microcomputer chip, and microcomputer chip rings circuit, display driver circuit, controlable electric current and keyboard 7 through lead connection detection circuit, news respectively.
See also shown in Figure 1 again, power circuit 1 is connected to form through lead by transformer B, rectifier D1, D2, D3, D4, voltage-stablizer 7805 and transistor T4, the transformer secondary output coil connects rectifier and transistor base stage, this transistor colelctor electrode connects microcomputer chip, grounded emitter, rectifier output end connects voltage-stablizer.This circuit provides energy source and power to each several part, input AC 220V, output direct current 5V.
See also shown in Figure 1 again, testing circuit 2 is connected to form through lead by gas-sensitive head Q, transistor T5, indicator lamp D5, D6 and resistance, electric capacity, gas-sensitive head connects power circuit 1 positive pole, exports the colelctor electrode that connects microcomputer chip 6 and transistor T5 respectively, and the base stage of this transistor connects microcomputer chip, grounded emitter.The function of this circuit is converted to signal of telecommunication output with oil smoke or pernicious gas.
See also shown in Figure 1ly again, news are rung circuit 3 and are connected to form through lead by transistor T6, loudspeaker S and resistance, and this transistor base stage connects microcomputer chip 6, colelctor electrode connects loudspeaker, grounded emitter.Square-wave signal about the 4KH2 that the function of this circuit produces the FT001 microcomputer chip amplifies output.
See also shown in Figure 1 again, display driver circuit 4 is connected to form through lead by charactron HDSP5321, transistor T7, T8, driver 78HC164, crystal resonator C1 and resistance, transistor T7, T8 emitter stage connect that power circuit 1 positive pole, colelctor electrode connect charactron, base stage connects microcomputer chip, charactron connects driver through lead, resistance, and driver connects microcomputer chip, crystal resonator through lead connection microcomputer chip and driver through lead.Information such as function display setting remaining time time of this circuit and gas-sensitive head test data.
See also shown in Figure 1 again, controlable electric current 5 is connected to form through lead by blower fan M, controllable silicon T1, T2, T3, indicator lamp D7, D8, D9, signal lamp X1, X2 and resistance, electric capacity, blower fan connects power supply through controllable silicon T1, T2, signal lamp connects power supply through controllable silicon T3, and the control utmost point of controllable silicon T1, T2, T3 connects microcomputer chip through indicator lamp.This circuit is an executing agency, for blower fan is strong, weak, signal lamp etc. carried out switch control.
See also shown in Figure 2 again, the used microcomputer chip FT001 of the utility model is eight special microprocessors, electric parameter to artificial input instruction and gas-sensitive head is analyzed, computing, control, processing, storage, determine, the command output signal each several part carries out that corresponding action is carried out and the acousto-optic indication.
When the utility model uses, insert the 220V power supply, entire controller powers on, be in holding state, this moment, then power supply indicator D6 lighted by keyboard 7 input instructions, and each functional indicator light D7, D8, D9 light accordingly, news are rung and are sent the sound that ticks by loudspeaker S after circuit triode T6 amplifies simultaneously, and drive blower fan M work.When by display driver circuit 4 incoming timings instruction, the conducting of triode T7, T8 wheel scan flow, the serial of FT001 microcomputer chip output simultaneously particular data, be converted to the parallel data signal control charactron XS display setting time through driver 78HC164, minute to be that unit carries out the countdown counting, its reference frequency is to obtain after C1 crystal resonator frequency division this moment, and the degree of accuracy is quite high, after timing arrives, the sound prompting eight of ticking.As with the K1 closure, FT001 pin 13 becomes low level, after then timing arrives, will close on ﹠ off switch by internal control, has also just closed each executing agency, has reached the timing shutdown purpose.When the instruction of input automaticmanual, indicator lamp D6 lights, FT001 micro computer output order blocks gas-sensitive head output 1 minute, simultaneously parameters such as the resistance of gas-sensitive head, sensitive spot are detected, and and the parameter of inner storage compare, adjust, make it to be in optimum state, normal as gas-sensitive head, then open internal controller.As undesired (open circuit, short circuit), then sending ticks points out the user to check two, then closes automatic transmission (but other each function normal running).After detecting normally, controller is in automatic monitor state, as running into pernicious gas or oil smoke, gas-sensitive head resistance generation acute variation is after FT001 detects this variation, then start the air draft of blower fan high speed, pernicious gas or oil smoke are lower than finite concentration, after delaying time 1 minute, cut off motor again, make it the filth-discharging effect that reaches desirable, be in monitor state next time simultaneously again.When first perception oil smoke, also can send the four tones of standard Chinese pronunciation that tick and tick and be D6 flicker, alerting safety.
The utility model alternating-current pulse signal is taken from the secondary of B, through after the T4 shaping, sends into FT001, this signal is carried out one-time detection with several milliseconds, guaranteeing its operate as normal, and this blackout, all functions except that timer will lose efficacy.
