In order to facilitate understanding of the above-described technical aspects of the present invention, the above-described technical aspects of the present invention will be described in detail below in terms of specific usage.
As shown in fig. 4, the recognition device of the present invention is not provided in the body of the existing intense pulsed light therapeutic apparatus, and the filter bearing plate with the filter also has no recognition mark, so that the present invention is improved.
In an embodiment of the invention, the filter detection plate is connected to the filter mounting groove of the intense pulsed light therapeutic apparatus in a detachable connection manner, such as a slot manner, so that the filter detection plate is convenient to maintain and replace.
The reflecting optical coupler in the invention is also called a photoelectric isolator or a photoelectric coupler, and is called an optical coupler for short. The device is a device for transmitting electric signals by taking light as a medium, and usually a light emitter (an infrared Light Emitting Diode (LED)) and a light receiver (a photosensitive semiconductor tube and a photosensitive resistor) are packaged in the same tube shell. When the input end is electrified, the light emitter emits light, and the light receiver receives the light, then the light generates photocurrent which flows out from the output end, thereby realizing 'electro-optic-electro' control. The photoelectric coupler takes light as a medium to couple an input end signal to an output end, and perfectly solves the problems of space and temperature rise of the groove type optical coupler because the photoelectric coupler has the advantages of small volume, long service life, no contact, strong anti-interference capability and insulation between output and input.
In one embodiment of the invention, the black and white stripes on the filter bearing plate are close to the reflective optocoupler (with a distance of 1-4 mm), the reflective optocoupler light irradiates on the black and white stripes, and then the black and white stripes reflect back to the optical coupler receiving end. The optical coupler outputs a corresponding voltage signal according to the intensity of the return light, and the voltage signal is converted by the comparison and amplification circuit. The power supply voltage of the circuit is 5V power supply, 2.5V is used as reference voltage, when the detection output signal is lower than 2.5V, the comparison amplification circuit outputs low level 0, otherwise, high level 1 is output.
In one embodiment of the invention, 4 transmitting optocouplers are arranged on the filter detection plate, corresponding identification marks (black and white stripes) are arranged on the filter bearing plate, when laser emitted by the detection plate irradiates on the white stripes of the filters, the white stripes reflect the laser back, and the detection plate receives the reflected laser and outputs a high level 1; when the laser emitted by the detection plate irradiates on the black stripe of the filter plate, the black stripe absorbs the laser and does not reflect, the detection plate does not receive the reflected laser, and the low level 0 is output. The detection board detects 0 and 1 corresponding to different stripe outputs of the filter through the four-way reflector to distinguish the wavelength of the filter, as shown in fig. 5, 4 transmitting optical couplers can obtain 16 combined signals, for example, if an identification mark sequentially comprises black-white stripes, the output combined signal is 0001, the wavelength of the filter bearing plate with the identification mark is 400 & &800 & & 1200, the system can display the model of the filter, then the light emitting mode and the light emitting energy are intelligently selected to achieve the optimal treatment effect, wherein particularly, if the output combined signal is 0000, the condition that no filter exists or the filter is not installed in place (for example, the distance is not proper) is indicated, and the filter is installed again after the detection.
The number of the emission optocouplers in the invention can exceed 4, the wavelengths of the filters can be subdivided, more types of filters can be arranged for accurate treatment, corresponding identification marks are made (the identification marks can be pasted in a patch mode), and the stripe colors of the identification marks are not limited to black and white and can be other colors.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
