Abstract
Description
Technical Field
[0001] The present application relates to the field of radar detection technology, and in particular to a laser radar with a disinfection function, a cargo transport vehicle, and a disinfection robot. Background Art
[0002] Based on the need to disinfect viruses and microorganisms, it is sometimes necessary to disinfect specific environments (such as hospitals or cold storage warehouses). The existing disinfection method generally involves fixed installation of disinfection tools in a specific environment to achieve chemical disinfection (such as fungicides, etc.) and / or physical disinfection (such as ultraviolet rays, etc.). Chemical disinfection may cause residual substances on the surface of environmental objects, which has certain risk factors. In contrast, physical disinfection is more conducive to disinfection because there are no residual substances. However, due to the fixed setting of existing physical disinfection in the environment, the coverage of a single disinfection tool is limited, and it is impossible to fully and thoroughly disinfect the entire specific environment; although multiple devices increase the coverage of disinfection, it will also lead to an increase in overall costs. Therefore, how to provide a high-coverage and low-cost disinfection tool has become a technical problem that needs to be solved by those skilled in the art. Summary of the Invention
[0003] In view of this, the embodiments of the present application provide a laser radar with disinfection function, a cargo transport vehicle and a disinfection robot, which effectively reduce costs while ensuring high disinfection coverage.
[0004] In a first aspect, the embodiments of the present application disclose a laser radar with a disinfecting function, comprising:
[0005] Transmitting components and receiving components are sequentially arranged along the direction of the laser light path;
[0006] The emitting component is used to emit a laser beam, and the laser beam is scanned toward the target area along a first straight line direction.
[0007] The emission component is also used to simultaneously emit ultraviolet rays with a sterilizing function, and the ultraviolet rays and the laser beam have the same scanning trajectory;
[0008] The receiving component receives the echo laser beam reflected by the target area.

[0012] The laser radar of the present application simultaneously emits a laser beam with a detection function and ultraviolet rays with a disinfection function through a transmitting component. Since the ultraviolet rays and the laser beam have the same scanning trajectory, the ultraviolet rays will scan back and forth in the field of view of the laser radar, thereby completing a large range of physical disinfection; and since there is a large gap between the wavelength of the ultraviolet rays and the wavelength of the laser beam, the interference is low and it is easy to filter, which will not affect the detection function of the laser radar.

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0024] The components of the embodiments of the present application generally described and illustrated in the drawings herein may be arranged and designed in a variety of different configurations.

[0027] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.
[0028] Based on the need to disinfect viruses and microorganisms, it is sometimes necessary to disinfect specific environments (such as hospitals or cold storage warehouses). The existing disinfection method generally involves fixed installation of disinfection tools in a specific environment to achieve chemical disinfection (such as fungicides, etc.) and / or physical disinfection (such as ultraviolet rays, etc.). Chemical disinfection can easily lead to residual substances on the surface of environmental objects, which has certain risk factors. In contrast, physical disinfection is more conducive to disinfection because there are no residual substances. However, since physical disinfection is fixed in the environment, a single disinfection tool cannot fully and thoroughly disinfect the entire specific environment. Although multiple devices increase the coverage of disinfection, it will also lead to an increase in overall costs.
[0029] Specifically, the embodiment of the present application first provides a laser radar with a disinfection function through the following embodiment 1, which mainly introduces how to achieve large-scale physical disinfection from a technical perspective. In subsequent embodiments, the specific application scenarios of this technology will be introduced.
[0030] Example 1
[0031] like Figure 1 As shown, this embodiment provides a laser radar with a disinfecting function, comprising: a transmitting component 1 and a receiving component 2 arranged in sequence along the direction of the laser light path;
[0032] The emitting component 1 is used to emit a laser beam, and the laser beam is scanned toward the target area AA along a first straight line direction.
[0033] The emission component 1 is also used to simultaneously emit ultraviolet rays with a sterilizing function, and the ultraviolet rays and the laser beam have the same scanning trajectory;
[0034] The receiving component 2 receives the echo laser beam reflected by the target area AA.
[0035] The emitting component 1 emits laser light, the wavelength of which can be 905 nm, 1550 nm or other wavelengths. In this embodiment, 1550 nm is preferably used.
[0036] The emitting component 1 emits ultraviolet light, the wavelength of which can be 100-400 nm, preferably 240-280 nm. If it is in accordance with relevant technical requirements, the optimal wavelength can be 253.7 nm.
[0037] The receiving component 2 can be an avalanche photodiode (APD), a PIN photodiode (PIN PD), a single photo avalanche photodiode (SPAD), or a multi-pixel photo counter (MPPC). The specific type of the receiving component 2 is selected based on the detection sensitivity, detection distance, and response speed.
[0038] In one embodiment, the transmitting assembly 1 includes a plurality of first transmitting units 1.1 and a plurality of second transmitting units 1.2;
[0039] The first transmitting unit 1.1 is used to transmit a laser beam with a preset frequency and a detection function;
[0040] The second emitting unit 1.2 is used to emit ultraviolet rays with a disinfection function;
[0041] The plurality of first emitting units 1.1 and the plurality of second emitting units 1.2 are all arranged on the same plane, and simultaneously emit laser light with a detection function and ultraviolet light with a disinfection function at a preset frequency.
[0042] In practical applications, the specific arrangement of the first transmitting unit 1.1 and the second transmitting unit 1.2 can be set as needed. Figures 2 to 4 , three feasible arrangement modes are given as examples to illustrate this embodiment.
[0043] This embodiment shows the first way, Figure 2 As shown, first emitting unit 1.1 and second emitting unit 1.2 are spaced apart from each other. The advantage of this arrangement is that the first emitting units 1.1 and second emitting units 1.2 are evenly distributed throughout emitting assembly 1. This achieves an optimal balance between the detection and disinfection functions of the laser radar, eliminating the issue of inconsistencies between the laser beam scanning area and the ultraviolet light scanning area. Furthermore, since the two are isolated from each other, each first emitting unit 1.1 is essentially affected in the same way, making overall debugging very simple.
[0044] This embodiment shows the second way, Figure 3 As shown, first emitting units 1.1 are arranged in columns and rows; second emitting units 1.2 are arranged in columns and rows; the columns and rows of first emitting units 1.1 and the columns and rows of second emitting units 1.2 are spaced apart. The advantage of this arrangement is that the overall structure of the emitting assembly is relatively clear and simple, ensuring that the scanning area of the laser beam and the scanning area of the ultraviolet light are basically consistent. Each first emitting unit 1.1 is essentially affected in the same horizontal and vertical directions (the specific direction depends on the column and row arrangement), making overall debugging easier.
[0045] This embodiment shows the third way, Figure 4 As shown, the first transmitting unit 1.1 is provided with the second transmitting unit 1.2 on the periphery. The advantage of the above arrangement is that the area formed by the first transmitting unit 1.1 and the area formed by the second transmitting unit 1.2 will not be confused with each other, making installation, assembly, inspection and maintenance easier.
[0046] It is understandable that Figures 2 to 4 This is only an illustrative example. In actual applications, it is not necessary to set the arrangement according to the arrangement method in the above figure. The number of arrays in the figure is not limited in this application.
[0047] In one embodiment, Figure 5 As shown, the receiving assembly further includes an isolation sheet 2.1 and a receiving array 2.2, wherein,
[0048] The spacer only allows the reflected light beam of the preset frequency to pass through;
[0049] According to the direction of the optical path, the reflected light beam first passes through the isolation plate 2.1 and then is received by the receiving component 2.2.
[0050] In practical applications, to prevent the potential impact of ultraviolet light on receiving component 2, a spacer 2.1 can be provided that only allows laser beams of a specific wavelength to pass through. All light entering receiving component 2.2 must first be filtered by spacer 2.1 before being received by receiving component 2.2. Furthermore, due to the significant difference between the wavelength of ultraviolet light and the wavelength of the laser beam, the parameter requirements for spacer 2.1 are relatively relaxed, and the filtering effect is excellent.
[0051] In one embodiment, Figure 6 As shown, the laser radar further includes a scanning mirror 3, which is used to split the laser beam and ultraviolet light emitted by the emitting component 1. The scanning mirror 3 includes a top surface 3.1 and a bottom surface 3.2 arranged opposite to each other, and includes a plurality of side surfaces 3.3 connected in sequence between the top surface 3.1 and the bottom surface 3.2. The side surfaces 3.3 are used to deflect the incident laser beam and ultraviolet light respectively. Figure 7 shown.
[0052] In practical applications, in order to reduce the number of transmitting units in the transmitting assembly, beam splitting can be performed by a scanning mirror 3. Utilizing the beam splitting function of the scanning mirror, an incident laser beam / ultraviolet light can be split into multiple beams and projected onto the target area AA, so that each laser beam / ultraviolet light can cover a larger area, which helps to reduce the volume and weight of the transmitting assembly and effectively lower costs.
[0053] In one embodiment, Figure 8 As shown, at least one side surface 3.3 is divided into a plurality of sub-side surfaces 3.3.1 along the second straight line direction, an angle is formed between two adjacent sub-side surfaces 3.3.1, and the angles between the plurality of sub-side surfaces 3.3.1 and the top surface 3.1 are different.
[0054] In practical applications, based on the detection capabilities of LiDAR, dense laser beams are not necessary for distant objects, but are required for close objects. Therefore, the aforementioned side profiles can be used to create a dense laser beam pattern near the scanning mirror and a sparse pattern far away.
[0055] In this embodiment, the emission component simultaneously emits a laser beam with a detection function and ultraviolet light with a disinfection function, thereby achieving the following beneficial effects:
[0056] 1. Since the laser beam will scan back and forth within the field of view of the LiDAR, and since the ultraviolet light and the laser beam have the same scanning trajectory, the ultraviolet light will also scan back and forth within the field of view of the LiDAR, thus completing a large-scale physical disinfection;
[0057] 2. The wavelength of ultraviolet light differs significantly from that of laser beams. For example, ultraviolet light is 253.7nm, while laser beams are 1550nm. These two wavelengths fall just on opposite sides of visible light, making them less susceptible to mutual interference. Technically, it's easy to filter out ultraviolet light to prevent it from affecting the receiving components. Therefore, the detection capabilities of the lidar will not be affected by adding a UV disinfection function.
[0058] Example 2
[0059] This second embodiment introduces the technical solution provided in the first embodiment of this application from the perspective of specific applications. Specifically, laser radars can be divided into mechanical laser radars, hybrid solid-state laser radars, and solid-state laser radars. Below, from the perspective of specific applications, examples are given to illustrate the application of the technical solution of the first embodiment to various types of laser radars.
[0060] Mechanical lidar
[0061] Exemplarily, this embodiment provides a mechanical laser radar with a disinfecting function, including:
[0062] The transmitting component 1 and the receiving component 2 are sequentially arranged along the direction of the laser light path;
[0063] A driving assembly for driving the transmitting assembly 1 and the receiving assembly 2 to rotate;
[0064] Driven by the driving component, the emitting component 1 rotates and emits a laser beam, which is scanned toward the target area AA along the first straight line direction.
[0065] At the same time, the emitting component 1 also emits ultraviolet rays with a sterilizing function, and the ultraviolet rays have the same scanning trajectory as the laser beam;
[0066] The receiving component 2 receives the echo laser beam reflected by the target area AA.
[0067] In practical applications, the transmitting component 1 and the receiving component 2 can be arranged side by side vertically, side by side horizontally, or side by side opposite to each other. The specific arrangement can be set according to actual needs.
[0068] In the above-mentioned mechanical laser radar, since the driving component can drive the transmitting component 1 and the receiving component 2 to rotate up to 360 degrees, the disinfection work can be carried out in a field of view of up to 360 degrees, achieving the lowest cost disinfection work.
[0069] Exemplarily, this embodiment provides another mechanical laser radar with a disinfecting function, including:
[0070] The transmitting component 1, the scanning mirror 3 and the receiving component 2 are sequentially arranged along the laser light path;
[0071] and a driving assembly for driving the scanning mirror 3 to rotate;
[0072] The receiving component 2 receives the echo laser beam reflected by the target area AA.
[0073] Driven by the driving component, the scanning mirror 3 rotates, so that the emitting component 1 emits a mixed light beam containing a laser beam and ultraviolet light, which can pass through the rotating scanning mirror and scan within the field of view of the laser radar, thereby realizing the detection function and the disinfection function at the same time.
[0074] In addition, the scanning mirror 3 can also be used to split the mixed light beam emitted by the emitting component 1. The scanning mirror 3 includes a top surface 3.1 and a bottom surface 3.2 arranged opposite to each other, and a plurality of side surfaces 3.3 connected in sequence between the top surface 3.1 and the bottom surface 3.2. The side surfaces 3.3 are used to deflect the incident laser beam and ultraviolet light respectively.
[0075] Because the angles between the side surfaces 3.3 and the top surface 3.1 of the scanning mirror 3 are different, the mixed light beam emitted by the transmitting assembly 1 is refracted when it enters any of the side surfaces 3.3. The varying angles between the side surfaces 3.3 and the top surface 3.1 cause the refraction to occur at different locations, thus enabling the scanning mirror 3 to achieve a beam splitting function. This in turn expands the coverage of the single mixed light beam, extending both the detection and disinfection functions.
[0076] In practical applications, it is not necessary for every side surface to have a different angle with the top surface. The number of different angles between the side surfaces and the top surface can be selected according to actual needs.
[0077] In the above-mentioned mechanical laser radar, due to the beam splitting function of the scanning mirror, each mixed light beam can cover a larger area, reducing the number of transmitting units, thereby reducing the volume and weight of the transmitting component and effectively reducing the cost.
[0078] Exemplarily, this embodiment provides a hybrid solid-state laser radar with a disinfecting function, including:
[0079] The transmitting component 1, the galvanometer, the scanning mirror 3 and the receiving component 2 are sequentially arranged along the laser light path;
[0080] The galvanometer is used to change the emission component 1 to emit a mixed light beam containing a laser beam and ultraviolet light;
[0081] The receiving component 2 receives the echo laser beam reflected by the target area AA.
[0082] The emission component 1 emits a mixed light beam containing laser beam, ultraviolet light and can be scanned within the field of view of the laser radar through the galvanometer and scanning mirror 3, thereby realizing the detection function and the disinfecting function at the same time.
[0083] In practical applications, the scanning mirror 3 may also have a beam splitting function. The specific principle and working method have been explained in the above examples and will not be repeated here.
[0084] In practical applications, the galvanometer can be a micro-electro-mechanical system (MEMS) scanning mirror. The MEMS galvanometer is a reflective lens installed on a MEMS chip. Both the front and back surfaces of the reflective lens are coated with a high-reflectivity film layer, and both can scan, transmit, or receive laser beams. The type of MEMS chip can be divided into electrostatic drive, electromagnetic drive, piezoelectric drive, or thermoelectric drive, etc. The MEMS chip galvanometer can also be replaced by a rotatable reflector, such as a reflective lens placed on a one-dimensional or two-dimensional rotating platform, and both the front and back surfaces of the reflective lens are also coated with a high-reflectivity film layer.
[0085] The hybrid solid-state LiDAR's smaller rotating structure allows for a smaller size. Furthermore, since the transmitting component doesn't require a rotating structure, the LiDAR's overall stability is higher, making it more compatible with automotive-grade requirements.
[0086] It is understood that the specific structure of each component of the above-mentioned laser radar can be referred to the specific structural description of each component of the laser radar in Example 1. The structures of each component are similar and will not be repeated here. In addition, some optional options or preferred options in Example 1 are also applicable to the above-mentioned Example 2.
[0087] Example 3
[0088] This third embodiment introduces the technical solution provided by the embodiments of the present application from the perspective of specific applications. Specifically, the application scenario in the third embodiment is a space to be disinfected, such as a warehouse. For the disinfection of goods that need to be shipped out, the general process is to first take the goods from the shelves by a cargo transport vehicle, and then transport them to a designated area for disinfection. This will result in the actual shipment of goods requiring additional disinfection time, resulting in reduced shipping efficiency. In order to improve the efficiency of shipping out, one way is to install enough disinfection tools in the warehouse. Since each disinfection tool can only cover a certain fixed area, the above method will require continuous addition of disinfection tools as the area of the warehouse increases, and the cost will also increase accordingly; another way is to use a disinfection robot, but it will increase the number of movable objects in the warehouse, increase the probability of collision, and the cost of the disinfection robot is much higher than that of a simple disinfection tool.
[0089] Example 3 is mainly based on the above scenario and discloses a cargo transport vehicle, including a laser radar, which includes: a transmitting component and a receiving component arranged in sequence along the direction of the laser light path; the transmitting component is used to transmit a laser beam, and the laser beam is scanned and emitted along a first straight line direction toward the target area AA. The transmitting component is also used to simultaneously emit ultraviolet rays with a disinfection function, and the ultraviolet rays and the laser beam have the same scanning trajectory; the receiving component receives the echo laser beam reflected by the target area AA.
[0090] In Example 3, since the emitting assembly also emits ultraviolet light with a disinfecting function, the ultraviolet light and the laser beam have the same scanning trajectory. Therefore, the ultraviolet light also scans back and forth within the laser radar's field of view, performing disinfection operations. Since the goods leaving the warehouse are always within the field of view of at least one laser radar, disinfection is completed during transportation, eliminating the need for a unified disinfection process and improving work efficiency. Furthermore, since the cargo transport vehicle is in motion, the environment within the laser radar's field of view is constantly updated, significantly increasing the coverage area of the cargo transport vehicle compared to fixed disinfection tools. Furthermore, since the laser radar integrates the ultraviolet light emission function, the need for a separate disinfection robot is eliminated, reducing the number of moving objects in the warehouse, the probability of collisions, and the cost of disinfection. Secondly, since there can never be just one cargo transport vehicle in a warehouse, once the number of cargo transport vehicles reaches a certain level, the area of the combined field of view of the laser radars of all cargo transport vehicles can reach a very large area.
[0091] It's also important to note that while the truck is operating, the transport area (and therefore the disinfection area) must be unoccupied. Because ultraviolet disinfection on trucks releases high-power ultraviolet radiation, exposure to this radiation could have adverse effects on the human body (however, since ultraviolet disinfection doesn't cause secondary pollution, workers can enter the warehouse after the truck is shut down). Therefore, the truck can be operated remotely or under computerized automated control.
[0092] In practical applications, to prevent interference between the warehouse and the external environment, a first disinfection module can be installed at the bottom of the unmanned cargo transport vehicle to disinfect the vehicle's moving components (such as tires, pulleys, tracks, etc.). The disinfection module can continue to use physical disinfection methods (such as ultraviolet light) as well as chemical disinfection methods (such as fungicides).
[0093] In practice, to strengthen the disinfection of outbound goods, a second disinfection module can be added to the cargo support during cargo transportation. This module can continue to disinfect the outbound goods on the cargo support. This disinfection module can use not only physical disinfection methods (such as ultraviolet light) but also chemical disinfection methods (such as fungicides).
[0094] It is understood that the specific structure of each component of the above-mentioned laser radar can be referred to the specific structural description of each component of the laser radar in Example 1. The structures of each component are similar and will not be repeated here. In addition, some optional options or preferred options in Example 1 are also applicable to the above-mentioned Example 3.
[0095] Example 4
[0096] This fourth embodiment introduces the technical solutions provided by the embodiments of the present application from the perspective of specific applications. Specifically, the application scenario in the third embodiment is a space to be disinfected, such as a hospital. For disinfection of part or all areas of a hospital, one existing method is to install disinfection tools in the hospital. Since each disinfection tool can only cover a certain fixed area, the above method will require the continuous addition of disinfection tools as the area to be disinfected increases, and the cost will also increase accordingly; another method is to use a disinfection robot, which itself needs to be equipped with a navigation device.
[0097] Example 4 is mainly based on the above scenario and discloses a disinfection robot, including a laser radar, which includes: a transmitting component and a receiving component arranged in sequence along the direction of the laser light path; the transmitting component is used to emit a laser beam, and the laser beam is scanned and emitted along a first straight line direction toward the target area AA. The transmitting component is also used to simultaneously emit ultraviolet rays with a disinfection function, and the ultraviolet rays and the laser beam have the same scanning trajectory; the receiving component receives the echo laser beam reflected by the target area AA.
[0098] In Example 4, since the emitting component also emits ultraviolet light with a disinfection function, and the ultraviolet light and the laser beam have the same scanning trajectory, the ultraviolet light will also scan back and forth within the laser radar's field of view to perform disinfection work. Because the disinfection robot itself is in a moving state, the environment within the laser radar's field of view is constantly updated, so the disinfection robot's coverage area is greatly improved compared to fixed disinfection tools. At the same time, because the laser radar integrates the ultraviolet light emission function, there is no need to configure an additional disinfection module separately on the mobile robot, reducing the overall disinfection cost.
[0099] In the several embodiments provided in this application, it should be understood that the disclosed devices may also be implemented in other ways, and the device embodiments described above are merely illustrative. In addition, the functional modules or units in the various embodiments of this application may be integrated together to form an independent part, or each module may exist independently, or two or more modules may be integrated to form an independent part.
[0100] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed in this application, which should be covered by the scope of protection of the present application.
