The complete machine job description:
1. electricity enters duty automatically: turn on the power switch, internal electric source wave circuit after filtration powers up to complete machine.The monolithic machine carries out safety inspection by power-on reset circuit and internal control program to circuit, enters the clock work state automatically, display window read clock value after checking normally.
2. function setting explanation: the function conversion of this circuit is by singly-bound cycling assignment procedure, when pressing function button for the first time, receiver enters " wireline inspection " function, press for the second time that receiver enters " safe voltage detections " function, press successively again this key for " adjust during clock, clock divide adjust, adjust during alarm clock, alarm clock divides adjustment, function and use introduction, enter wait " etc. function.After entering function corresponding, press setting key again and carry out functional parameter is set.
3. control method explanation: this machine is to carry out man-machine conversation by single-chip microcomputer 16 by button and display to finish automatic control.The major control method is that single-chip microcomputer 16 selects electronic switch and signal processing circuit current supply circuit to finish according to different function setting output corresponding instruction deactivations accordingly.Export corresponding voice address instruction simultaneously and start voice warning circuit, finish sound prompt function, and the corresponding sign prompting of output in indicator gate.When the circuit measuring ability, single-chip microcomputer 16 provides power supply to the A9 limb of signal Processing 8119 chips 5, make this signal processor work, finish that the signal that electromagnetic sensor is sent here is selected, processing and amplifying, directly signal is delivered to note amplifier carry out power amplification from the metastable signal of A7 limb output amplitude of chip 5 through automatically adjusting function then, deliver to loudspeaker at last and export by threshold switch diode 8 and diode 9 are in parallel.When the safe voltage measuring ability, single-chip microcomputer 16 startups detect voltage detecting input port logical signal, when finding that input port is logic low, single-chip microcomputer 16 sends corresponding voice address instruction to sound circuit, it is in parallel with diode 9 that the startup sound circuit is delivered to threshold switch diode 8 by audio output port C3 through coupling capacitance 7, through threshold switch signal is delivered to note amplifier and carry out power amplification, deliver to loudspeaker output at last.Voice heart sheet is to single-chip microcomputer 16 instruction of giving notice after prompt tone output finishes, single-chip microcomputer 16 begins the voltage input end mouth is detected after having notice and instructing again, when input port also was logic low, single-chip microcomputer 16 repeated above process again, goes on so repeatedly.During only to voltage detecting input port input high level, single-chip microcomputer 16 just can stop to send enabled instruction to speech chip.Gas detection function constantly: the process that this function is implemented is to control by the interrupt control mode.In order to limit Overall Power Consumption, this machine is provided with special control switch to sensor circuit, when its function operation, should close this gauge tap.When opening the sensor gauge tap, single-chip microcomputer 16 also is set to the interrupt control mode automatically.When harmful gas exceeds standard when making the testing circuit output low level, single-chip microcomputer 16 interrupts from dynamic response.The process of interrupting is that single-chip microcomputer 16 sends corresponding voice address instruction to sound circuit, start sound circuit and 7 deliver to threshold switch through being coupled by audio output port C3 output prompting sound signal, signal is delivered to note amplifier carry out power amplification through threshold switch diode 8 and diode 9 are in parallel, deliver to loudspeaker output at last.Automatically close interrupt control during single-chip microcomputer 16 enters interrupt response, speech chip is to single-chip microcomputer 16 instruction of giving notice after prompt tone output finishes.Automatically open interrupt control again after single-chip microcomputer 16 has notice instruction, if at this moment Detection Circuit or output low level, single-chip microcomputer 16 can enter interrupt response again, repeats the above course of work, output voice suggestion so continuously.Only export high level or close the sensing control switch to Detection Circuit, single-chip microcomputer 16 just can not send instruction and stop voice suggestion to speech chip.
