Description
Technical field
The invention belongs to light detection field, relate in particular to optocoupler sensing device.
Background technology
Optocoupler sensor is divided into two kinds:
Reflective: refer to that the receiving-member of optocoupler sensor and emission element are in a same side, reflective optocoupler sensor is integral type optocoupler sensor; The light signal emissive source of optocoupler sensor is launched light signal, on the path of light signal process, may have reflected light signal barrier (can reflected light signal), light signal is reflected back, at this moment the sensitization check point that optocoupler detects just can detect light signal, while there is no barrier on the path of light signal process, the sensitization check point of optocoupler sensor just can't detect light signal; This mode can be used for by arrange reflection or reflected light signal do not identify and use current location status or optocoupler sensor the place ahead of equipment of optocoupler sensor whether to have object; In actual applications, in the working environment of optocoupler sensor, can there is such-and-such stray light signal, and the material of existing optocoupler sensor itself also can printing opacity, the material of the penetrable optocoupler sensor photosensitive of stray light signal check point part, arrives sensitization check point from the side or below; The existence of stray light signal causes the detection of optocoupler sensor to make mistakes.As shown in Figure 1,1 is reflective optocoupler sensor, the circle that vertical line is filled is the light signal emissive source of optocoupler sensor 1, the circle that horizontal line is filled is the sensitization check point of optocoupler sensor 1, arrow a represents the light signal of light signal emissive source transmitting, arrow b, c, d, e, f represent stray light signal, A is the barrier of reflected light signal, B is for absorbing the barrier (i.e. this barrier both light tight also reflected light not) of light signal, from diagram, stray light signal b and the c A that all breaks the barriers reflexes to the sensitization check point of optocoupler detecting device, causes detected state mistake; Stray light signal d will be absorbed after being irradiated to barrier B, so on detecting without impact; Stray light signal e, f arrive sensitization check point near sensitization check point, also can cause detected state mistake.
Another kind is incident-type: refer to that the light signal emissive source of optocoupler sensor is on the opposite of the sensitization check point of optocoupler sensor, be that incident-type optocoupler sensor is a split type optocoupler sensor, while having lighttight barrier in the middle of light signal emissive source and sensitization check point, optocoupler sensor just can't detect the light signal of the light signal emissive source transmitting on opposite, and this mode can be used for identifying to use between the current location status of the equipment of optocoupler sensor or optocoupler sensor and light signal emissive source whether have object according to light signal whether being detected; As shown in Figure 2,1a is the receiving-member of incident-type optocoupler sensor, and 1b is the emission element of incident-type optocoupler sensor; The circle that vertical line is filled is light signal emissive source, the circle that horizontal line is filled is sensitization check point, arrow a represents the light signal of light signal emissive source transmitting, arrow b, c, d represent stray light signal, B is light tight barrier, from diagram, stray light signal b, c, d can arrive sensitization check point, cause state-detection mistake.
The error-detecting causing in order to solve stray light signal, prior art is generally used or uses the optocoupler detecting device that can avoid environmental interference light signal wave band to detect by optocoupler detecting device being placed on do not have under noisy closed environment, and this is restricted the application of optocoupler sensor.
