Programmable control method is inserted in choosing, with many plug-in unit or light transmitting fibers 74, according to " three figure, one table " and outgoing position with two above plugs 71 of lead 73 connections, speed, acceleration over time rule when low pressure when plate or high pressure the plate diverse location select respectively and insert corresponding timing pulse (dashing during abbreviation) unit hour h, minute min, second s and millisecond ms often open or normally closed logical, " or ", the inverter jack is programmed for required " self-marketing ", " forbid " " jumping choosing ", " meter is recalled ", " counting ", " displacement ", " corner ", the method that difference in functionality logic gates such as " speed governing " is set.Program can nested procedure, according to the different permutation and combination of logic array, the function of program is increased greatly.Three figure, one table is meant the processing parts process chart, the processing synoptic diagram, and transfer matic is always got in touch dimensional drawing, part or transfer matic dust cycle table.

In real system, output may be various physical quantitys such as position, speed, temperature, flow, pressure.Yet in theory was analyzed, output was which kind of physical quantity is unimportant, and important is outgoing position, speed, the time dependent rule of acceleration.

The programming Control device is inserted in choosing, when it inserts low pressure by many plug-in units that are used to programme and choosing when plate or high pressure plate form.

The present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement.

High pressure and low tension loop electricity are isolated and anti-interference problem; The isolation of interchange and direct current or direct current and alternating voltage is to adopt transformer to do isolator, and the method for conversion direct current and alternating voltage is to form various forms of electronic ac switch with semiconductor diode or triode to reach this purpose.Adopting pulse transformer is the contact on circuit for insulation triggering circuit and controllable silicon main circuit, and therefore obtains suitable trigger voltage.Disturb with Xc.

The present invention by light and luminous effect element separation after, add again, during high pressure when plate and low pressure two regulate of plate guaranteed.

Controllable silicon is to the requirement of trigger circuit; Controllable silicon has two by the external condition that off state becomes conducting state, and the first circuit anode potential is higher than cathode potential; Add suitable forward trigger voltage and current signal between the second control utmost point and the negative electrode.Change the commutating voltage size, also should change silicon controlled service time, promptly change the phase place of trigger pip, these all are the tasks that trigger circuit should be finished.1. control utmost point characterisitic parameter, trigger voltage (V) 0.15～5, trigger current (mA) 0.4～400.2. trigger waveform, the forward position is strong triggers and triggers two parts of platform.3. enough phase shift ranges are arranged, and it is relevant with the rectification circuit connection.4. pulse time of sending and main circuit voltage waveform change should certain corresponding relation, is referred to as " synchronously ".Each thyristor has trigger separately, also has synchronizing voltage separately.The trigger input is a control voltage, and output is pulse phase shifting angle a.The effect of synchronism link is that controllable silicon can both be triggered at identical a angle in each cycle of power supply, just requires the frequency of triggering identical with the frequency of main circuit power synchronously.

The present invention is with photoelectric cell open-circuit voltage (V) 0.45～0.65, operating voltage (V) 0.31～0.42, short-circuit current (mA) 2～140, frequency 10 ¹⁴～10 ¹⁵Hz do to trigger power supply, phase shift range and phase place " synchronously " during by low pressure plate adjusting and photronic frequency guaranteed.

The supply voltage frequency 50Hz of direct current motor is the end of than, and silicon controlled rectification power source contains more output ripple after conversion, and percent ripple has great variation with the wiring pattern and the use-pattern of silicon controlled rectifier.In order to improve this situation and the reaction velocity of accelerating signal, normal employing increases the method for the rectification number of phases, and 12 phases, 24 phase or 36 phases adopt the high frequency electric source of 1000Hz to 5000Hz.Have again, the thyristor supply electric current changes rapidly, has temporal variations fast.These characteristics have increased machinery to direct current motor, and heat and burden electric aspect have especially increased the difficulty of commutation.Thus direct current motor is produced the problem of some designs on going up and using, motor must design to such an extent that adapt to the harm of harmonic current and temporal variations fast.Direct current motor is at unit, and aspects such as electric pressure and raising rotating speed are gradually in the limit.Because the restriction of commutation, the direct current motor ceiling voltage can only reach 1000V, and AC motor is that it is more than 10 times.Because simple in structure, easily manufactured, the low price of AC motor, maintenance cost is low, volume is little, in light weight, save aspect such as operating cost, and these all are the weak links of DC speed regulation transmission, but however, promote the AC speed regulating transmission and still have big difficulty, be because opertaing device cost height, problem such as operational efficiency is low.

And the cost height mainly is a Power Conversion is on-off element change of current problem; Converter plant provides the power supply of variable frequency and variable voltage for governing system.And to the friendship of an AC motor power supply ac frequency converter always, except input AC and direct current with the output direct current and exchange two aspects with the transformer isolation, ask employing forced commutation in loop in the direct current, require to force controllable silicon to turn-off at the special change of current circuit of the inner employing of current transformer.It has higher requirement to used thyristor, while complex circuit, shortcomings such as cost height.

The present invention solves the Power Conversion problem like this; Autocontrol and controllable silicon nature commutation mode are adopted in frequency control, promptly hand over alternation speed governing frequently.AC power is directly become the power supply of variable frequency and voltage, therefore also be referred to as Direct Conversion device or periodic transformation device, only change the form of electric energy with linear transformation.Because of power supply itself has Low ESR, make it have the character of voltage source, therefore, the quadergy of load motor (being inductive) is directly cushioned by power supply.Do not have dependence between its change of current ability and the output voltage, the two regulating actions of plate when plate and high pressure when adding low pressure can be carried out wide frequency modulation, pressure regulation, phase place, transform vector control to motor.Can predict large, medium and small power ac motor speed control and will replace dc motor speed regulating, be a very important breakthrough in Electrical Control of Machinery Tools equipment and electric automatic control field.
