In an automatic state, a main input signal from a regulator passes through an I/V conversion and isolating circuit, the A/D conversion of the main input signal can be realized, the main input signal can be sent into a D/A converter through the reversible counter of a hand and an automatic control units, the signal after the conversion can be sent to a light pillar to display via a light pillar drive circuit, and high-brightness LED digital display in 3.5 digits can be realized simultaneously; in a manual state, when the utility model is automatically switched to a hand-operated mode, the moment figure can be latched and switched by the count register in the hand and the automatic control units, and the main input signal can be output through the D/A conversion and the V/I conversion isolating circuits. The utility model can clearly and visually know the opening size of a valve position in a long distance, and the utility model has an excellent interference immunity.
Description
The utility model relates to the monitoring device of general control systems, relates in particular to light beam and shows manual operator.
All need the energy, material etc. to regulate and control in various industries such as chemical industry, light industry, medicine, food, as steam, hot water, chilled water, slurry and various chemical materials etc. to pipeline transportation.
The flow control of these materials must be undertaken by variable valve.And the adjusting of control valve opening size when manual (manually) mode of operation, then must be finished by manual operator, therefore regulates when tending a gate to rely on well behaved manual operator to finish in manually-operated.
Because operation is carried out in the pulpit away from variable valve often, therefore must carry out feedback and tracking and indication, so that the operator regulates to the aperture situation of Field adjustment valve.
Existing various manual operator often is not with output indication gauge outfit, or only indicates with very little gauge outfit, so its index error is very big, and is difficult for clearly reading.On the other hand, its circuit structure is not taked quarantine measures, so anti-interference is poor, is subject to external interference, the influence operation.General manual operator does not possess hand/do not have automatically disturbance handoff functionality, when carrying out hand/automatic switchover, often introduces very big interference, is unfavorable for producing normally.
The purpose of this utility model provides a kind of smooth osmanthus and shows manual operator.
The utility model is taked following measures in order to achieve the above object: when it is included in auto state, the output tracking input value, the primary input signal that self tuning regulator comes is behind I/V conversion and buffer circuit, change through A/D, enter D/A converter by the up-down counter in hand, the automatic control unit, signal after the conversion shows by light beam driving circuit to light beam, and simultaneously with
Bit digital, the high-brightness LED numeral shows, when manual state, when automatically switching to manually, hand, counter register in the automatic control unit latchs and switches moment numerical value, change through D/A, export behind the V/I conversion buffer circuit, instantaneous value before having kept this moment switching, realize no disturbance switching, the adjusting of manual state output size, by " increasing ", " subtract " key and the logical controlling circuit is finished, when pressing " increasing ", when " subtracting " key, corresponding output valve and displayed value be " increase " or " reducing " also thereupon, after the input of valve position feedback signal, after I/V isolates change-over circuit, to the current valve seat opening value of high brightness LED light beam demonstration, feature is hand/automatic control circuit by 556 integrated circuit U1 is that core is formed oscillator and made impulse source, 4011 integrated circuit U2, U3 is a Sheffer stroke gate, 4071 integrated circuit U4 are or door and 4013 integrated circuit U5, trigger D composition increases, subtract counting gauge tap circuit, in order to control 4516 integrated circuit U6, the up-down counter that U7 forms, U6, the U7 up-down counter is formed A/D, data transmission channel between the D/A, in order to finish data counts and to latch, 4071 integrated circuit U4,4013 integrated circuit U5 form counting increase and decrease control circuit, work as U6, when 1 pin of U7 is high level, be in " automatically " state, data line DB0～DB7 changes with input D0～D7, works as U6, when 1 pin of U7 is low level, be in " manually " state, data line DB0～DB7 increases with UP or DOWN or reduces.
The utility model has the advantages that:
1. output indication is shown by the high-brightness LED light beam, larger distance can the present valve seat opening of clear and intuitive understanding size, and the LED reliability of service life is long far beyond the electromagnetic system gauge outfit.
2. for ease of the manual accurately aperture of operation valve, be equipped with valve position numeral opening value and shown, made the accurately aperture of regulating and controlling valve of operating personnel.
3. all adopt electric quarantine measures between all inputs, output signal, the power supply, make instrument have fabulous anti-interference, strengthened the instrument reliability of operation greatly.
4. be equipped with the valve position position feedback to detect, and clearly indicate the aperture of current actual valve position with the light beam form.
