Description
The present invention relates to a kind of time controller of using microelectric technique, the time zone that specifically relates to a kind of four loops able to programme is controlled arbitrarily, have simultaneously automatic or manual can preset the meter second, multi-functional controllers such as timing, counting, frequency division, meter frequency.
At present, the time controller of producing both at home and abroad has polytype.From domestic, it is time-controlled that most type design become the logic timing circuit to realize, this time controller precision is lower, and the programming mode inconvenience of employing plug-in type or switching regulator, make mistakes easily, be to adopt the microprocessor technology in addition, the TP801 single card microcomputer is adapted as programmable time controller, as: " the micro processor controls multi-path timer " of Shanghai electric automatization Research Institute, the sort controller timing function is complete, accurate, but cost is higher, and many functions of single card microcomputer are wasted.And physical dimension is big, is not suitable for the timing control unit as electromechanical equipment or instrument and meter.The repetitive cycling cycle of the control program of above-mentioned two types of time controllers is 24 hours, and applicable surface is narrower.And the product of external timing controller also is to adopt the logic timing circuit to be designed to the timer or the device of tailored version at the seventies initial stage majority, but put on market in recent years a kind of be to adopt the time controller that can control three loops that single chip microcomputer is designed to, for example: the COMPU series timing controller that U.S. NEW company produces.This time controller precision height, but function ratio is more single, and steering order is also few, only is suitable for the separate unit electromechanical equipment or the timing controlled of electrical equipment and simple process process, and is inapplicable for the control of comparatively complicated industrial product process procedure.Also having a kind of is the Programmable Logic Controller (PC) that adopts the various types microprocessor Design, as " the GE-PC series programmable controller " of GE's production.This Programmable Logic Controller (PC) is with logical operation, sequential operation, regularly, control programs such as counting and arithmetical operation carry out large scale process control or form distributed control system with a series of instruction types, involve great expense, one up to thousands of extremely tens thousand of dollars, this is suitable for for the higher production run of some automaticities and the control of process equipment, but for the timing in the general production process of a large amount of medium-sized and small enterprises, the Automatic Combined unit and the electromechanical equipment of the programmed control of timing and counting and periodic cycle, the timed unit of instrument and meter and automatic production record or the like is if also adopt Programmable Logic Controller (PC), many functions of controller can not play a role, obviously waste one's talent on a petty job, increase the complicacy of technological process control on the contrary, caused waste.
In sum, from the time controller of producing both at home and abroad at present, a kind of is that price comparison is suitable, but function is too single, is not suitable for the control requirement of industrial manufacture process; Another kind is that function is more complete, but price is too expensive, also is not suitable for the time control in the general production process of medium-sized and small enterprises.
The purpose of this invention is to provide and a kind ofly can overcome the multifunction programmable time controller that there is shortcoming in above-mentioned time controller, this time controller has simple in structure, easy to operate, cheap.It can realize any control of sequential in the multiloop time zone, can realize the independent use of functions such as automatic or manual meter second, timing, counting, frequency division, meter frequency again, can also combination in any and set control program, to satisfy many types of formula, multi-level control needs.
According to purpose of the present invention, the inventor has designed the main circuit of a kind of four single chip microcomputers of special use as time controller, this special-purpose single-chip microcomputer is designed to program mode, many original function commentaries on classics for hardware are finished by software, and the multi-functional software of design is once filled in the ROM into special purpose computer, make the one-chip computer of design have four kinds of functions such as timing, timing, counting, meter frequency, the external memorizer (RAM) that to expand a capacity in addition be 1K * 4 is used as sequential control specially.The quartz oscillator of configuration high stability, and, guaranteed the high precision of timing and sequential control by pre-regulator fine setting resonant frequency of a crystal.
Time controller is designed to the sequential control (being timer) of four passages according to the goal of the invention inventor.The control program establishment of four passages is any formula, and can compile instruction is 4 * 60.It is 1 second or 1 minute that the time interval is set minimum, is 1 hour to the maximum or 24 hours, period departure≤± 0.01 second.Simultaneously, in order to guarantee reliability of operation, can in the control program establishment of four passages, design there be six can supply the encryption apparatus of setting arbitrarily.Timer, counter, frequency counter adopt the form of each two passage compatibility, can import various photoelectric pulse signals like this and in order to changing sensing element signal that resistance is feature and on-off type electrical contact switch signal or the like, startup can preset set self-clocking and to above-mentioned various signals count automatically, frequency division, meter frequently.
Relay output is all adopted in the output control frequently of sequential control and timing, counting, meter.Use the in parallel or series connection of output relay or feedback combination can realize four kinds of function combination in any and sequential control and realize by minute, by the hour or per diem, by the sequential cycle period in week or by the control requirement of determining the time in the week arbitrarily, to satisfy many types of formula, multi-level programmed control.
Also device taking alarm is exported also in the control of above-mentioned four passages, is implemented in the initial of control and the instantaneous warning that stops.
The multifunction programmable time controller of making according to above-mentioned design concept compared with prior art has following advantage: one, the present invention adopts the one-chip computer of specific program formula as main circuit, both can realize the control of programmable multicircuit time, have functions such as timing, counting, meter frequency, frequency division again, timing simultaneously is with regularly accurate, the precision height, day accuracy of timekeeping is adjustable second at 0.1-0.3; Two, control program of the present invention establishment, the setting of time, operating instruction, function self check and input data all adopt the keyboard establishment, and directly input is directly perceived, simple, be easy to grasp, and the while reprogramming is flexible; Three, reliability height of the present invention, good to rugged surroundings adaptability, antijamming capability is strong, and the present invention once Shanghai Observatory, CAS is responsible for carrying out all events type approval test.To major function of the present invention, the degree of accuracy of function and to the environment of various settings, as, influence such as power failure, voltage, temperature, magnetic field, weather and anti-top shake ability or the like project testing result has all been reached the requirement of technical conditions regulations; Four, the present invention is simple in structure, and size is little, and the complete machine hardware circuit is few, and the complete machine parts are formed simple, are made of main circuit board, stabilized voltage supply, input keyboard and cabinet; Five, the present invention has the optimum ratio of performance to price.Cost of the present invention is about 10 dollars, and external single loop programmable time controller lowest price also is more than 1,000 dollars, compares much also cheap with domestic existing product.
