Perception unit 11 is used for obtaining extraneous environmental information, the size of such as relevant with one or more ambient parameter physical quantity and situation of change, and communicate to connect with processing unit 15 thus this environmental information is passed to processing unit 15, as the foundation regulating dimming glass transparency.
In the present embodiment, perception unit 11 is ultrasonic distance sensor, it is arranged near dimming glass, and be connected with processing unit by RS232 interface, whether have people near dimming glass and the distance measured people and dimming glass between, and then can present different transparencies according to the difference control dimming glass of distance if being used for detecting, such as, along with reducing of people and glass distance, allow glass become more and more transparent, thus realize a kind of transparency control effects of real-time change.
Those skilled in the art will recognize that, in the solution of the present invention, be not limited to and use ultrasonic distance sensor, but various common type sensor can be adopted, such as infrared distance sensor, laser range sensor, pyroelectric infrared sensor, microwave remote sensor, illuminance transducer etc.
Those skilled in the art it should further be appreciated that, in scheme of the present utility model, perception unit is not limited to sensor, and it can be also only the interface be connected with external sensor or other parts, as long as can receive the signal regulating dimming glass transparency according to this.Such as, perception unit can be the interface be connected with such as manual slip knob, button etc., can support the transparency controlling glass in a manual fashion thus.According to the needs of practical application, perception unit can be used to provide any parameter in external environment.
And, before the environmental information of the acquisition collected is passed to processing unit, perception unit 11 can carry out pretreatment to corresponding signal, this signal is converted to the form being suitable for processing unit and carrying out processing, such as different signal forms and/or signal format.
Direct current voltage reulation unit 12 and processing unit 15 communicate to connect, and input, according to the voltage control instructions that processing unit 15 provides, regulate it to export to the DC voltage of orthogonal inversion unit for the direct current based on outside.
In actual applications, for the different model of dimming glass, direct current voltage reulation unit 12 can export different voltage, and representative value is 48V.
