Embodiment 2:
Introduced microprocessor on the basis of embodiment 1, the annexation block diagram of each module as shown in Figure 5.The core of present embodiment is a microprocessor, proximity transducer (photoelectric sensor, ultrasonic sensor or voltage sensitive sensor etc.) output signal is to microprocessor, the microprocessor output alarm signal is to alarm, the output call signal is to calling set, the output control signal is controlled the action of automatically controlled folder, microprocessor also is connected with the reservation port, is used for the function expansion of this transfusion controller.
Described automatically controlled folder is electromagnetism iron clamp or cam clamping device (as shown in Figure 4) etc.
In addition, the drive circuit between microprocessor or proximity transducer (or other pick offs) and the automatically controlled folder can adopt multiple mode.As follows:
As shown in Figure 6, this drive circuit adopts audion T as switching device, be in series with a resistance R and relay coil J between the colelctor electrode of audion T and the power supply vcc, input signal in is the output signal (level signal or pulse signal) of an output port of microprocessor, or the outputs level signals of proximity transducer, or the output signal of proximity transducer is through a pulse signal of pulse delay unit output, the state of the normally opened contact K of relay is as output, the normally opened contact K of relay can insert in as shown in Figure 4 the circuit (being relay normally open contact 12), is used to start micro machine.The normally opened contact K of relay can be connected in the circuit of electromagnetism iron clamp, is used to control the action of electromagnetism iron clamp.When signal in is high level (perhaps pulse signal positive pulse), audion T conducting, relay coil J invocation point, the actuating of relay, normally opened contact K closes, micro machine or the action of electromagnetism iron clamp; Otherwise as signal in is low level (voltage is zero or is negative), and then audion T ends, not conducting of circuit, and the relay coil dead electricity resets, and normally opened contact is opened, and can be used for controlling the action of electromagnetism iron clamp or cam clamping device thus.
Circuit as shown in Figure 7 is a simple signal amplification circuit, input signal in is the output signal (level signal or pulse signal) of an output port of microprocessor, or the outputs level signals of proximity transducer (in case of necessity through a non-output more behind the door), or the output signal of proximity transducer is through a pulse signal of pulse delay unit output, signal in connects the base stage of audion T, the colelctor electrode of audion T meets positive supply vcc by a resistance R, collector terminal is outfan out, outfan out can connect the micro machine or the electromagnetism iron clamp of cam clamping device, and as the positive power source terminal of this micro machine or electromagnetism iron clamp.Its operation principle is as follows, when signal in is a high level, and audion T conducting, output signal out is a low level, micro machine does not start, or the electromagnetism iron clamp is failure to actuate; Otherwise when signal in is a low level, audion T ends, and outfan out exports high level, and then micro machine starts, or the action of electromagnetism iron clamp.As seen, this circuit is that low level is effective, therefore, where necessary, at input in place or outfan out place add a not gate, make logic control relation more smooth and easy, then can use this circuit more expediently.
For described cam clamping device, its control signal (as signal in) preferably adopts impulse form because adopt pulse can realize micro machine in a setting-up time electric rotation, and if adopt the level form, then micro machine after startup always electric, influence service life of micro machine.For microprocessor, be easy to realize from pulse signal of an I/O port output; For the device that does not adopt microprocessor, then between signal of sensor and signal in, add a pulse generator and get final product.
