Referring to fig. 2, a first embodiment of the present invention provides a photoelectric pair control method, which can be executed by a photoelectric pair control device, and in particular, by one or more controllers in the photoelectric pair control device, to implement the following steps:
in the use state, the following steps are repeated:
s101, controlling a transmitter of a photoelectric pair to send a signal, and setting a detection interface connected with one end of a detection pin of a receiver to be in an input level state so as to receive a detection value input by the detection pin for a first time; wherein the other end of the detection pin is connected to a collector of the receiver.
And S102, after the first time, controlling the transmitter to stop sending signals, setting the detection interface to be in a low level output state, so as to output low level to the detection pin, and continuing for a second time.
In this embodiment, the photoelectric pair control device is an electronic device including a photoelectric pair, for example, a printer or the like. The photoelectric pair can be used as a sensor in the electronic equipment to detect some working states of the electronic equipment. For example, the open/close state of the electronic apparatus and the position of the print medium are detected.
As shown in fig. 1, fig. 1 shows a partial circuit schematic of a photoelectric pair in an electronic device. In general, the photoelectric pair 10 comprises an emitter 11 and a receiver 12, the receiver 12 is a triode, and includes a base, a collector 3 and an emitter 4, the base corresponds to the emitter 11, the collector 3 is connected to a power supply voltage terminal 30 of a power supply and a detection pin 20 of a controller. The emitter 4 is grounded. The emitter 11 is a photodiode, the anode of which is also connected to the supply voltage terminal of the power supply.
In the present embodiment, the controller has a detection interface and is connected to the detection pin 20 through the detection interface to monitor the on state of the receiver 12 through the detection pin 20. When the base of the receiver 12 does not receive the signal transmitted by the transmitter 11 (for example, in a non-operating state, or when the signal transmitted by the transmitter is blocked by a printing medium, or the signal transmitted by the transmitter is not received by the receiver), the collector 3 and the emitter 4 are in a non-conducting state, the voltage of the collector 3 is higher than the voltage of the emitter 4 (generally, the voltage of the collector 3 is the voltage of the supply voltage terminal 30), and when the receiver 12 receives the signal transmitted by the transmitter 11, the collector 3 and the emitter 4 are in a conducting state, and the voltage of the collector 3 is equal to the voltage of the emitter 4 (generally, both are 0).
From the above analysis it can be seen that when the collector 3 and the emitter 4 are in a non-conducting state, the voltage of the collector 3 is higher than the voltage of the emitter 4, i.e. there is a voltage difference between the collector 3 and the emitter 4 when they are not conducting. During operation, it is normal that the collector 3 and the emitter 4 are not conductive. For example, when there is paper between the transmitter 11 and the receiver 12 or when the transmitter 11 does not transmit a signal or the transmitter 11 transmits a signal that is not received by the receiver 12, neither the collector 3 nor the emitter 4 is conductive. This voltage difference will therefore exist for a long time, and this long-lasting voltage difference will lead to silver migration between the collector 3 and the emitter 4, and thus to a false conduction of the collector 3 and the emitter 4 when the emitter 11 is not emitting a signal.
To solve the above problem, in the use state, the present embodiment repeats the following steps:
firstly, the emitter 11 of the photoelectric pair 10 is controlled to send out a signal, and meanwhile, a detection interface connected with one end of a detection pin 20 of the receiver 12 is set to be in an input level state so as to receive a detection value input by the detection pin 20 and keep for a first time.
In this embodiment, the use state refers to a non-power-off state and a non-sleep state. In the use state, the controller firstly controls the emitter 11 of the photoelectric pair 10 to send out a signal for a first time, and simultaneously the controller sets the detection interface to be in an input level state, so that the detection pin 20 can input a level signal to the controller through the detection interface. At this time, the controller may determine whether the collector 3 and the emitter 4 are conductive according to the level signal detected by the detection pin 20.
Then, after a first time duration, the detection interface is set to output a low state to output a low level to the detection pin 20 for a second time duration.
In this embodiment, since the monitoring of the controller does not need to exist all the time, it only needs to be acquired once in one acquisition period. Therefore, after the first time, the controller sets the detection interface to output a low level state to output a low level to the detection pin 20, so that the voltage of the collector 3 can be reduced to zero, and further the voltage difference between the collector 3 and the emitter 4 is gradually reduced to 0, thereby reducing the generation of silver migration.
It should be noted that, in this embodiment, during the second time, the transmitter 11 may be set to stop transmitting the signal, or may be set to continuously transmit the signal, and since the controller continuously outputs the low level to the detection pin 20 during the second time, no voltage difference or a large voltage difference exists between the collector and the emitter 3 and the emitter 4 of the receiver 12 at this time regardless of whether the transmitter 11 transmits the signal.
In summary, in the photoelectric pair control method provided in this embodiment, when the photoelectric pair is in the non-operating state, the detection pin 20 outputs the low level state to the collector 3, so that the voltage difference between the collector 3 and the emitter 4 is gradually reduced to 0, thereby effectively improving the occurrence of silver migration, and avoiding the occurrence of false conduction.
In order to facilitate an understanding of the invention, some preferred embodiments of the invention are described further below.
In the present embodiment, the supply voltage terminal 30 will continuously supply power to the collector 3 in the use state. The voltage is continuously supplied, so that the reaction time of the whole circuit is relatively short, in the scheme, the input and output states of the detection interface are directly controlled, and the reaction time is microsecond, so that the first time can be designed to be microsecond level, the time with voltage difference is shorter, and the possibility of silver migration is further reduced.
Furthermore, in a preferred embodiment, generally, the second time should be greater than the first time. In particular, the second time is ten times or more the first time.
