One, overview

DYK type guide vane opening device for hydropower station guide vanes, gate opening, servomotor stroke, shaft angle measurement and the development of a high precision, high applicability of products, collection instrument transmitter signal, can display the displacement, the opening percentage, can be arbitrarily set eight alarm output, at the same time has analog output.

In two, features                                                         

The single chip microcomputer system using MCS-51series, through the internal divider generates measurement of timing pulse, a period of 2us, its precision can reach0.01Hz, high stability, long.

The display circuit using high brightness dynamic display program.

The signal input circuit of photoelectric isolation. The value of the signal into the computer, and then converted into the corresponding displacement value, opening percentage content display, memory.

The8 output signals were amplified to drive the relay output, wherein the 8action point and displacement values are set corresponding to the set value, the measured displacement, the corresponding output contact action.

The advanced WATCHDOG and voltage monitoring circuit of computer work to monitor the situation, when the power on, power off or voltage is unstable, with the industry standard SPI serial memory can protect the information in the computer. When a computer crash, the watchdog can automatically generate a reset signal to restart the computer work, greatly improves the reliability of the instrument.

The steady state power switch, AC, DC can work stably, and the voltage change does not affect the measurement device reliability.

Three, technical parameters

Measurement signal: displacement sensor signal form: current4 ~ 20mA

The measurement accuracy of < 0.3%: nonlinear

The digital content: displacement value, the opening percentage, each output setting.

The switch output signal: 8, every point by the user in a certain range setting.

The output capacity:5A / 250VAC,5A / 30VDC.

Analog output : 4 ~20mA (corresponding to 0% ~ 100% degree)

Work environment:0to 50 DEG C temperature humidity is lower than 85%

Working mode: continuous

The power: 110V / 220VDC or AC110/ 220V / 50Hz

The power:10W

Four, work principle

DYK guide vane opening instrument accept displacement sensor. The analog signal, the A / D conversion to send CPU numerical computation, the calculation of numerical respectively displacement volume, opening a percentage, while the eight output alarm output and analog, and the alarm value and range can be set arbitrarily, can completely replace the mechanical type master switch.
