The code scanning component 200 may include an aiming component 210 and a camera component 220.

The aiming component 210 may be a laser generator, which is used to emit an aiming laser and mark the code reading area of ​​the camera component 220, so that the user can quickly align the code reading area corresponding to the camera component 220 with the barcode label to be identified.

[0038] Please refer to Figure 2, which is a block diagram of the driving composition principle of the code scanning device provided in this embodiment. The camera component 220 is arranged on the main circuit board 100, wherein the camera component 220 can be a camera and a corresponding photosensitive element. The photosensitive element is connected to the main circuit board 100 through MIPI IIC (Mobile Industry Processor Interface Inter-Integrated Circuit); the main circuit board 100 transmits data with the CPU (Central Processing Unit) in the code scanning device based on MIPI IIC. Exemplarily, the photosensitive element can be a CMOS (Complementary Metal-Oxide-Semiconductor) sensor, or a CCD (Charge-Coupled Device) sensor.

[0039] The aiming drive circuit corresponding to the aiming component 210 can be integrated on the main circuit board 100. The main circuit board 100 transmits data with the CPU in the code scanning device based on GPIO (General-Purpose Input / Output) to control the aiming component 210 to emit the aiming laser.

[0040] Exemplarily, the aiming component 210 includes a laser generator and a DOE (Diffractive Optical Element) lens; the laser generator receives a corresponding laser driving signal, generates laser light, and forms a cross laser through the DOE lens for aiming and marking the barcode label to be identified.

[0041] The lighting assembly 300 is connected to the main circuit board 100 and includes a first light source 310 and a second light source 320. The first light source 310 is used to enhance the brightness of the barcode label to be identified, and the second light source 320 is used to provide lighting to assist the user in inspecting the target object.

[0042] The first light source 310 is a fill light source for the scanning device, and can be implemented by using LED (Light Emitting Diode) lamp beads.

[0043] The second light source 320 is a light source for assisting the user in providing illumination when inspecting a target. Exemplarily, the second light source 320 is a light source for pupil inspection, or a light source for oral inspection.

The lighting driving circuit corresponding to the lighting assembly may include a first light source driving circuit and a second light source driving circuit. In a possible implementation, the first light source driving circuit of the first light source 310 is integrated on the main circuit board 100. The second light source driving circuit of the second light source 320 can be integrated on the main circuit board 100, or it can be independently set in the lighting assembly 300 from the main circuit board 100.

[0045] The code scanning component 200 and the lighting component 300 are arranged in parallel on the main circuit board 100 .

[0046] Exemplarily, other necessary electronic components may be disposed on the main circuit board 100 according to requirements, and the embodiments of the present application are not limited to this.

[0047] The code scanning device provided in the above embodiment includes a main circuit board 100 and a code scanning component 200 and a lighting component 300 arranged in parallel on the main circuit board 100, wherein the code scanning component 200 is connected to the main circuit board 100 for identifying barcode labels, and the lighting component 300 is connected to the main circuit board 100, wherein the lighting component 300 includes a light source for improving the brightness of the barcode label to be identified, and a second light source 320 is used to assist the user in providing lighting when inspecting the target; in this way, the above-mentioned code scanning device, on the basis of having the function of scanning medical barcode labels, adds the function of an auxiliary inspection light, thereby diversifying the functions of the code scanning device and enriching the application scenarios of the code scanning device.

[0048] Furthermore, the above-mentioned code scanning device is used in various scenarios of medical applications such as mobile nurse stations, outpatient infusion management, doctor's clinic ward management and drug distribution management, so as to avoid users carrying a lot of tools, which is conducive to doctors and nurses to check the patient's condition at any time and enable patients to receive timely treatment.

[0049] In an exemplary embodiment, the luminous flux of the second light source 320 in the lighting assembly 300 is smaller than the luminous flux of the first light source 310 , and the color rendering index of the second light source 320 is greater than a preset value.

[0050] Among them, the first light source 310 is mainly used to provide camera fill light for the code scanning device, which requires relatively strong brightness. The first light source 310 selects a light source with a relatively large luminous flux; exemplary, the luminous flux of the first light source 310 is 400Lm (lumens) to 500Lm; optionally, the luminous flux of the first light source 310 is 460Lm. The second light source 320 is mainly used to inspect the target object. In order to alleviate the stimulation of strong light to the eyes of the target object, the second light source 320 selects a light source with a relatively small luminous flux; exemplary, the luminous flux of the second light source 320 is less than 100Lm.

[0051] The color rendering index of the second light source 320 is greater than a preset value, wherein, in this embodiment, the color rendering index may also be referred to as the Ra color rendering index, which is the general color rendering index or the average color rendering index in Chinese. Exemplarily, the preset value may be 90; that is, the color rendering index of the second light source 320 is greater than 90. Of course, the preset value may also be 89 or 88, which are values ​​close to 90. In the embodiment of the present application, there is no limitation on the color rendering index of the first light source 310.

[0052] In this embodiment, a light source with a smaller luminous flux than the first light source 310 is used as the second light source 320, which can protect the eyes of the target object being inspected from being damaged by strong light; at the same time, the color rendering index of the second light source 320 is greater than a preset value. The larger color rendering index allows the second light source 320 to accurately display the original color of the inspected position of the target object, helping medical staff to make more accurate judgments.

[0053] In an exemplary embodiment, the second light source 320 includes more than two gears, and the lighting assembly 300 includes a second light source driving circuit, which is connected to the second light source 320 and is used to switch the gear of the second light source 320 .

[0054] Among them, the more than two gears may include a first gear for eye examination and a second gear for examination of other parts such as mouth and nose.

[0055] In the first gear, the color temperature of the second light source 320 is 2500K (Kelvin) to 3000K, and the luminous flux is 5Lm to 15Lm. In the second gear, the color temperature of the second light source 320 is 4500K to 5500K, and the luminous flux is 50Lm to 70Lm.

[0056] For example, in the first gear, the color temperature of the second light source 320 is 2700K, and the luminous flux is 10Lm, which is used to assist the user to perform eye examination on the target object without glare; in the second gear, the color temperature of the second light source 320 is 5000K, and the luminous flux is 60Lm, which is used to assist the user to perform mouth and nose examination on the target object, which is close to natural light and brighter. In this example, when the second light source is used to examine the target object, the demand for light source for medical examination is met, and the user experience of the object being examined can also be improved.

[0057] In a possible implementation, the second light source 320 may further include a third gear, and at least one of the color temperature or the luminous flux of the third gear is different from the first gear and the second gear to meet the diverse inspection lighting requirements. Exemplarily, the color temperature of the third gear is the same as that of the first gear, and the luminous flux is the same as that of the second gear; and another exemplary, the color temperature of the third gear is the same as that of the second gear, and the luminous flux is the same as that of the first gear.

[0058] In a possible implementation, the number of inspection lamps included in the second light source 320 is 1. In this implementation, the inspection lamp can change the color temperature and luminous flux based on the second light source driving circuit. Exemplarily, the second light source 320 can be an LED lamp bead; the second light source driving circuit can change the luminous flux of the second light source 320 by changing the voltage, current or pulse width modulation amplitude input to the second light source 320, and the LED lamp bead includes at least two light-emitting diodes, and the color temperature of the second light source 320 is changed by changing the primary color brightness ratio of each light-emitting diode, so as to achieve gear switching.

[0059] In a possible implementation, please refer to Figure 2, the second light source 320 includes a first inspection light 321 and a second inspection light 322, the first inspection light 321 corresponds to the first gear position, and the second inspection light 322 corresponds to the second gear position; the second light source driving circuit is used to control the on and off of the first inspection light 321 and the second inspection light 322 to switch the gear position.
