Description

Technical Field

[0001] The present invention relates to an electronic device, a data collection system and a method, and more particularly to an unmanned aerial vehicle, and a data collection system and a method using the unmanned aerial vehicle. Background Art

[0002] With the rapid development of integrated circuits, the environment for manufacturing electronic components needs to strictly control the amount of dust. For this reason, fan filter units (FFU) are often installed in manufacturing plants, mainly located on the top or floor of the plant to remove dust from the air.

[0003] FFU has a limited operating life and requires monitoring personnel to regularly check its filtering effect. Monitoring usually involves using lifting equipment to the top of the plant to check the operating status of the FFU one by one. This process is time-consuming, costly and has safety risks.

[0004] Although drones can be used to collect data in a designated area, operating drones in a factory requires not only familiarity with the location of the FFU, but also the high interference environment caused by other equipment in the factory makes operation more difficult. If a sensing device is installed on a currently available drone, it will not only affect the overall balance of the drone, but also increase the chance of the drone losing control.

[0005] In addition, the signal strength of the Global Positioning System (GPS) will also be affected by the shielding of the factory area, so GPS cannot be used as a flight reference for drones inside the factory area. This also increases the difficulty of controlling the flight of drones inside the factory area. Summary of the invention

[0082] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, there are respectively a scene schematic diagram of a data collection system 10 using a drone in one embodiment, a schematic diagram of a component architecture of a data collection system 10 of a drone device 100 in one embodiment, and a three-dimensional schematic diagram of a drone device 100 in one embodiment. The data collection system using a drone (hereinafter referred to as the data collection system 10) includes a drone device 100, an external measuring device 150 and a data collection device 200. The external measuring device 150 is configured outside the drone device 100 (to be described in detail later). The drone device 100 is connected to the data collection device 200 through a network. The drone device 100 can be used for data collection inside a factory area 300, and its operation will be described in detail later. The factory area 300 generally refers to the range within a factory building such as manufacturing, warehousing, quality inspection, clean room or packaging.

[0083] A plurality of fan filter units (hereinafter referred to as FFU310) are arranged inside the factory area 300. The FFU310 is arranged within a designated range of the factory area 300. For example, the FFU310 is arranged in the ceiling or side wall of the factory area 300. A designated area 330 is further arranged outside the air filter inlet of the FFU310. Figure 4 Generally speaking, a corresponding designated area 330 can be set for each FFU 310. Figure 4 In the figure, the dotted line box represents the designated area 330. Furthermore, the designated area 330 may be set outside the filter air inlet at the intersection of several FFUs 310. For example, the filter air inlet at the intersection of four adjacent FFUs 310 is set as the designated area 330.

[0084] The peripheral measuring device 150 has a single chip 151 and an environmental measuring unit 152. The single chip 151 is connected to the environmental measuring unit 152. The environmental measuring unit 152 is used to collect the amount of dust in the designated area 330. The amount of dust obtained by the environmental measuring unit 152 is referred to as dust data 194 below. The single chip 151 executes the HyperText Transfer Protocol (HTTP). The HTTP program 193 provides the dust data 194 to the connected client. The aforementioned client is not only the data collection device 200, but also other computers. The peripheral measuring device 150 can be implemented by integrating the single chip 151 or the Raspberry Pi with the environmental measuring unit 152. The peripheral measuring device 150 is connected to the drone device 100 and obtains the operating power of the single chip 151 and the environmental measuring unit 152.

[0085] The drone device 100 includes a body 110, at least one flight unit 120, a housing 130 and an outer cylinder 140. Figure 2 As shown. The body 110 further comprises a first communication unit 111, a power unit 112, a storage unit 113, a machine control sensing unit 114 and a control unit 115. The body 110 and each flight unit 120 are connected by respective connectors (without reference numerals). The housing 130 is disposed on the outer side of the body 110. The control unit 115 is connected to the first communication unit 111, the power unit 112, the storage unit 113 and the machine control sensing unit 114. The power unit 112 provides operating power to the flight unit 120, the peripheral measuring device 150, the machine control sensing unit 114, the control unit 115 and the first communication unit 111. In addition to controlling the action and output of the flight unit 120, the control unit 115 can also enable (or disable) the operation of the machine control sensing unit 114. The storage unit 113 stores a connection program 192. The control unit 115 executes the connection program 192 to connect to the data collection device 200 through a network and transmit the flight request 191.

[0086] When the drone device 100 is enabled, the control unit 115 obtains flight parameters through the machine control sensing unit 114 and adjusts the flight variables in real time. Among them, the machine control sensing unit 114 can be but not limited to an accelerometer, a gyroscope or a barometer, and the machine control sensing unit 114 provides the flight parameters obtained by the aforementioned various sensing. When the drone device 100 is flying, the machine control sensing unit 114 obtains flight parameters such as the speed, altitude, position, attitude (such as pitch angle, roll angle, yaw angle) or air pressure of the drone device 100. The machine control sensing unit 114 transmits the obtained flight parameters to the control unit 115. The control unit 115 adjusts the flight variables such as the motor speed, control surface deflection angle, thrust, etc. according to the flight parameters, thereby controlling the flight or hovering state of the drone device 100. The flight unit 120 provides the power for the horizontal and vertical movement or hovering of the drone device 100. The number of flight units 120 corresponds to the power for movement or hovering. Figure 3 The figure takes a four-axis flight unit 120 as an example, but in fact it can also be applied to a drone device 100 with a six-axis or more-axis flight unit 120.

[0087] A designated side surface 131 is disposed on one side of the housing 130. The designated side surface 131 is substantially parallel to the flight unit 120. One end of the housing outer cylinder 140 is disposed on the designated side surface 131, and the other end of the housing outer cylinder 140 is provided with an external measuring device 150. The housing outer cylinder 140 is disposed along the normal line of the designated side surface 131. Figure 3In other words, the outer shell column 140 and the designated side 131 (and the flight unit 120) are perpendicular to each other, and the position of the external measuring device 150 is higher than that of the flight unit 120. The external measuring device 150 is used to receive the amount of dust in the designated area 330 of the FFU 310. The first communication unit 111 receives the flight request 191, which includes the departure route, departure request, emergency return request, etc.

[0088] The control unit 115 drives the flight unit 120 to move to any position in the designated factory area 300 or hover in the designated area 330 according to the flight requirement 191. The first communication unit 111 can transmit the flight requirement 191 through a wireless network or Bluetooth wireless protocol. The peripheral measurement device 150 can also transmit the dust data 194 through a wireless network or Bluetooth wireless protocol. In some embodiments, the flight requirement 191 has a flight path 320 and a hovering time. The flight path 320 is composed of a plurality of continuous and designated spatial positions. The data collection device 200 can establish the flight path 320 according to the position sequence of the designated area 330, or load the established flight path 320 by other computing devices, so that the data collection device 200 can select the flight path 320 to be executed. The flight parameters of each position are recorded in the flight path 320 for the control unit 115 to determine whether the drone device 100 is offset (the processing description of determining the offset will be described later). The hovering time is the stay time when the drone device 100 is located in the designated area 330.

[0089] In some embodiments, such as in Figure 3 In the embodiment, the designated side surface 131 may be the upper side surface of the body 110, but is not limited thereto. The designated side surface 131 may also be two opposite side surfaces of the body 110, such as the front side surface and the rear side surface, or the left side surface and the right side surface. In this embodiment, one end of the outer cylinder 140 is still configured with the external measuring device 150, and the other end may form a "Y"-shaped structure (not shown), so that the other end of the outer cylinder 140 is disposed on the aforementioned two side surfaces.

[0090] In some embodiments, the height of the outer shell cylinder 140 corresponds to the hovering power of the flight unit 120. In order to reduce the interference of the airflow generated by the flight unit 120 when the drone device 100 is suspended on the external measuring device 150, the external measuring device 150 is installed at one end of the outer shell cylinder 140. Therefore, the height of the cylinder needs to match a height power relationship with the hovering power, thereby ensuring that the dust sensing effect of the external measuring device 150 will not be affected by the hovering power.

[0091] like Figure 4As shown, the combination of numbers at different positions of the outer shell cylinder 140 represents the wind speed per second at the position when the flight unit 120 is hovering for measurement. Figure 4 The central value set (10cm, 0.95m / s) is the hovering wind speed "0.95m / s" corresponding to the 10cm position of the outer shell cylinder 140. The value set (20cm, 0.75m / s) is the hovering wind speed "0.7m / s" corresponding to the 20cm position of the outer shell cylinder 140, and the rest of the value sets are similar. The control unit 115 can adjust the travel or hovering thrust of the flight unit 120 according to the corresponding relationship between the flight load and the altitude according to the real-time parameters of the machine control sensing unit 114.

[0092] In addition, the height of the outer shell column 140 and the external measuring device 150 configured will affect the stability of the drone device 100 during horizontal flight. Generally speaking, the outer shell column 140 can be in the shape of a long column, a long round column, or a streamlined long column.

[0093] The data collection device 200 has a second communication unit 210, a storage unit 220 and a processing unit 230. The data collection device 200 may be, but is not limited to, a mobile phone, a tablet computer, a laptop computer or a personal computer. The processing unit 230 is connected to the second communication unit 210 and the storage unit 220. The second communication unit 210 is connected to the drone device 100 through a network. The second communication unit 210 sends a flight request 191 to the first communication unit 111, so that the drone device 100 moves (or hovers) to a specified position. Alternatively, the second communication unit 210 receives dust data 194. In addition to the crawler program 221 and the report program 222, the storage unit 220 may also store the received dust data 194. The processing unit 230 stores the dust data 194 in the storage unit 220. The report program 222 generates an output result 223 based on the acquired dust data 194.

[0094] To further explain the operation process of the data collection of the drone device 100, please refer to Figure 5 , is a flow chart of a data collection method using a drone according to an embodiment. The operation of the data collection system 10 includes the following steps:

[0095] Step S510: The UAV device hovers to the designated area of ​​the FFU according to the flight requirements;

[0096] Step S520: The peripheral measuring device of the drone device obtains dust falling data of the designated area;

[0097] Step S530: the external measuring device executes a hypertext transfer program, so that the hypertext transfer program transmits the dust falling data;

[0098] Step S540: the crawler program network of the data collection end is connected to the external measurement device;

[0099] Step S550: the crawler program obtains dust falling data from the hypertext transfer program at a sampling period; and

[0100] Step S560: the data collection terminal generates an output result according to the dust falling data.

[0101] First, the drone device 100 is placed at an initial position inside the factory area 300. The initial position is selected according to the environment of each factory area 300. When the drone device 100 is at the initial position, the user can send a flight request 191 to the drone device 100 through the data collection device 200 to make the drone take off and move to the specified position. The drone device 100 moves to the specified area 330 according to the flight request 191 (corresponding to step S510). Then, the drone device 100 hovers in the specified area 330 and starts to obtain the dust falling data 194 of the specified area 330 (corresponding to step S520).

[0102] The hovering time of the drone device 100 depends on the capacity of the power unit 112 or the accuracy of the machine control sensing unit 114. Generally speaking, the longer the hovering time, the more dust data can be obtained. However, due to the power limitation of the power unit 112, the flight time and hovering time of the drone device 100 must also be considered. In addition, more types of environmental measurement units 152 are configured to obtain more accurate dust falling data 194. However, more sets of environmental measurement units 152 will also affect the weight and power consumption of the drone device 100 during flight.

[0103] In some embodiments, the user can select a flight path 320 with different environmental measurement units 152 in the display screen of the data collection device 200. Alternatively, the user can set a new flight requirement 191 through the data collection device 200 to create a new flight path 320.

[0104] After the drone device 100 is enabled, the control unit 115 starts to execute the connection program 192. The connection program 192 can provide the current flight information by publishing (POST), and the flight information includes flight altitude, flight position (i.e., spatial coordinates inside the plant 300), horizontal angle, vertical angle, route map, navigation progress, real-time video, power information, body abnormality information, abnormal autonomous return, etc. The connection program 192 obtains the flight request 191 by obtaining (GET), and the flight request 191 includes the departure route, departure request, emergency return request, etc. At the same time, the peripheral measurement device 150 executes the HTTP program 193 (corresponding to step S530).

[0105] After the drone device 100 is enabled, the data collection device 200 also executes the crawler program 221 (corresponding to step S540). The crawler program 221 obtains the dust data 194 from the HTTP program 193 at the frequency of the sampling period (corresponding to step S550). The peripheral measurement device 150 can provide a network address (IP address) to the data collection device 200 through a local area network (Local Area Network), so that the data collection device 200 is directly connected to the external measurement device 150. The data collection device 200 records the acquired dust data 194 in the storage unit 220. The report program 222 generates an output result 223 based on the acquired dust data 194 to display the dust data 194 of each designated area 330. The output result 223 can be a web page, a text file, or a comma-separated values ​​(CSV) file. Generally speaking, the raw data (raw data) of the dust data 194 may be a hexadecimal digital string, please refer to Figure 6 The report program 222 converts the dust falling data 194 into binary numbers or chart display results for the user to observe the dust falling amount in each designated area 330 . Figure 6 The dust data 194 obtained by using the PMS3 of Panteng Technology as the sensing unit is taken as an example, but the present invention is not limited to this.

[0106] In some embodiments, the drone device 100 further includes a first camera group 240 and a second camera group 250. Figure 7 . The control unit 115 is connected to the first camera group 240 and the second camera group 250. The first camera group 240 is arranged on the side of the main body 110. The second camera group 250 is arranged at the bottom of the main body 110. The first camera group 240 is used to shoot images in the horizontal direction, hereinafter referred to as horizontal images 241 (indicated by a dotted frame). The second camera group 250 is used to shoot images in the vertical direction, hereinafter referred to as vertical images 251 (indicated by a dotted frame). The first communication unit 111 can transmit the horizontal image 241 and the vertical image 251 to the data collection device 200 so that the user can view the front of the drone device 100 (corresponding to the content of the horizontal image 241). The control unit 115 infers the current location information within the factory based on the continuous changes between the multiple horizontal images 241 taken.

[0107] For example, the control unit 115 can realize the flight positioning of the drone device 100 inside the factory area 300 by using a Visual Simultaneous Localization and Mapping (VSLAM) algorithm or an Inertial Navigation System (INS) algorithm. Taking VSLAM as an example, the control unit 115 obtains image feature points at different positions inside the factory area 300 from each horizontal image 241. While the drone device 100 is flying, the machine control sensing unit 114 also obtains the current flight parameters. The control unit 115 determines the displacement change of the image feature points of each frame of the horizontal image 241 according to the flight parameters. The control unit 115 uses the obtained displacement change of the image feature points to correct the actual flight trajectory of the drone device 100. If the displacement change is greater than the threshold value, it means that the flight trajectory of the drone device 100 is offset. The control unit 115 then adjusts the flight unit 120 according to the horizontal image 241 and the flight parameters so that the current flight trajectory can be consistent with the preset flight path 320.

[0108] In addition, when the drone device 100 is flying, the first camera group 240 can also capture a horizontal image 241 with a two-dimensional barcode (QR Code). The control unit 115 obtains the machine number, model or related information of the production line machine, or the location number of the FFU 310 through the two-dimensional barcode of the horizontal image 241.
