Auto-manual autocontrol valve during the work time, mainly powers on process, normal workflow and urgent stream Three operating modes of journey, specifically:

1. powering on process

After system electrification, processor of single chip computer executes reset routine, drives 1 rotary closing valve of decelerating motor, examines simultaneously The output signal for surveying photoelectric encoder 102 illustrates that valve has been switched off when detecting that photoelectric encoder 102 stops counting Position, then counter O reset, and valve reset state=1 is marked, reseting procedure terminates.In reset routine implementation procedure, do not connect By the position control order that CANBUS bus transceiver is sent, only receive position enquiring order.

2. normal workflow

System enters normal workflow after reseting procedure.Normal response is sent out by CANBUS bus transceiver at this time The position control order sent, see Table 1 for details for position control command definition, and position control order is made of two parts: POS, MODE, Wherein POS indicates expected valve opening (0~100%)；MODE indicates the mode of work, after receiving control command, single-chip microcontroller meeting Photoelectric encoder count value C1 is calculated according to the set goal position T1, then starts PWM, and according to the position of current valve P1 and target position P2 calculates the rotation direction DIR of valve, if P1<P2, DIR=CCW(is counterclockwise), if P1>P2, Then DIR=CW(is clockwise), hardware interrupts are generated as count value C=C1 of high-speed counter, and stop PWM in interrupt function Output.

1 position control command definition of table

3. urgent process

When continuously multiple time cycles do not receive the control command sent by CANBUS bus transmitter or look into system Order is ask, means to have disconnected with master control system at this time, it is necessary to immediately enter urgent process.Urgent process is according to predetermined The timetable of justice adjusts valve.Urgent flow table definition such as table 2:

The definition of the urgent flow table of table 2

Such as: urgent flow table defines time 300, aperture 15；Time 600, aperture 20；Time 800, aperture 40；When even After connecing recovery, system exits urgent process, reenters controlled operating mode.

In the specific implementation process, control circuit 4 installs the side of decelerating motor 1, when starting pressurization, at single-chip microcontroller Reason device control auto-manual autocontrol valve is first automatically closed, and then requires to beat to the control of pressure further according to processor of single chip computer Valve opening, and the aperture with plateau quck-opening valve is controlled by data that photoelectric encoder 102 acquires.

The utility model with it is existing manually control square thread shut-off valve compared with, pass through computer acquire cabin pressure become Change data, by the open and close and aperture of CAN bus autocontrol valve, while rotation control can be carried out manually.In spies such as power failures In different situation, it is readily modified as manually controlling.If manually controlled more than buck standard, valve can correct aperture automatically.

It synthetically says, the auto-manual autocontrol valve of the utility model, valve arrangement is compact, and precision controlling is high.Control manually When processed, the problems such as strength when valve is closed regardless of operator, is not in motor rotation blockage, safety and stability is high. Valve automatic operating it is slim and graceful it is smooth, damping is suitable, without obvious noise, when can be manually rotated, dynamics is small, feel is light.

What the embodiments of the present invention were announced is preferred embodiment, and however, it is not limited to this, the common skill of this field Art personnel understand the spirit of the utility model easily according to above-described embodiment, and make different amplification and variation, but as long as The spirit of the utility model is not departed from, it is all within the protection scope of the present utility model.
