DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0026] In order to facilitate the reading of physical ID and improve the positioning accuracy, this embodiment proposes a physical ID and positioning information collection device, such as Figures 1 to 4As shown, it includes an RFID acquisition module 1, an infrared acquisition module 2, an optical scanning module 3, a positioning module 4, a processor module 5, a communication module 7, a laser ranging module 8 and a three-axis accelerometer 9 arranged in a handheld shell 101. The processor module 5 is connected to the positioning module 4 to collect positioning information. The positioning module 4 uses the RTK module of the Beidou satellite positioning system to achieve accurate positioning of the acquisition device. The processor module 5 is connected to the RFID acquisition module 1, the infrared acquisition module 2 and the optical scanning module 3 respectively to collect physical ID information. The processor module 5 is connected to the communication module 7 to interact with the external terminal device 102 through the communication module 7. The processor module 5 is connected to the laser ranging module 8 and the three-axis accelerometer 9 respectively to collect positioning correction information. The positioning information of the acquisition device can be corrected to the positioning information of the target object through the positioning correction information.

[0027] The collection device in this embodiment has three modes. Mode 1 uses RFID collection module 1, which is applied to the situation of high-altitude collection. RFID collection module 1 includes RFID reader / writer. The physical ID radio frequency tag and the RFID reader / writer realize spatial (contactless) coupling of radio frequency signals through coupling elements. In the coupling channel, according to the timing relationship, energy transfer and data conversion are realized to complete the automatic identification of the physical ID; Mode 2 uses infrared collection module 2, which is applied to the situation of container box collection. The infrared collection module 2 uses an internal laser device to shoot a laser light source point, which hits a reflective sheet with a mechanical structure device, and then relies on the vibration motor to swing the laser point on the bar code, and then is decoded into a digital signal through AD; Mode 3 uses optical scanning module 3, which is applied to the situation of contamination collection. The light emitted by the light source in the optical scanning module 3 is focused and reflected by the optical system of the physical ID bar code nameplate, and finally received by the detector in the optical scanning module 3 and converted into an electrical signal to complete the collection of physical ID information.

[0028] Considering that users work outdoors for a long time, it is necessary to ensure transmission speed and standby time. In this embodiment, the communication module 7 adopts a BLE5.2 module or a WIFI module, and the processor module 5 adopts a single-chip microcomputer.

[0029] It should be noted that the RFID acquisition module 1, the infrared acquisition module 2, and the optical scanning module 3 are all mature hardware modules. This embodiment does not involve improvements to their specific structures, and their specific structural compositions are not described in detail herein.

[0030] Through the above structure, the data collection device of this embodiment does not need to open the meter box, does not need to wait, and does not need to climb high, thus saving the entire data collection time and reducing safety risks.

[0031] like Figure 1 and Figure 4As shown, the acquisition device of this embodiment also includes a multi-way selection module 6 and a power supply module 10 arranged in a handheld shell 101. The power supply module 10 is connected to the power supply ends of the RFID acquisition module 1, the infrared acquisition module 2, and the optical scanning module 3 through the multi-way selection module 6, so as to select any one of the RFID acquisition module 1, the infrared acquisition module 2, and the optical scanning module 3 according to the actual scenario to collect physical ID information.

[0032] In this embodiment, the multi-way selection module 6 adopts a three-select-one paddle switch or a click switch, such as Figure 2 and Figure 3 As shown, the paddle switch or click switch button is arranged on the side of the handheld housing 101 for easy operation.

[0033] Correspondingly, in order to facilitate operators to clearly identify the selected modules, such as Figure 1 As shown, in this embodiment, a display module 11 is also provided. Specifically, Figure 2 As shown, the display module 11 is installed on the side of the handheld housing 101 and is located near the paddle of the paddle switch. In this embodiment, the display module 11 includes lamp beads corresponding to the RFID acquisition module 1, the infrared acquisition module 2, and the optical scanning module 3. Figure 4 As shown, these lamp beads are respectively arranged at the power supply ends of the RFID acquisition module 1, the infrared acquisition module 2, and the optical scanning module 3, so that when the paddle switch or the click switch of the multi-way selection module 6 is switched to the corresponding gear position, the lamp beads can be lit up due to power-on to prompt the selected module.

[0034] like Figure 4 As shown by the dotted lines in the figure, in this embodiment, the power module 10 is also connected to the power supply terminals of the positioning module 4, the communication module 7, the laser ranging module 8 and the three-axis accelerometer 9 respectively. The power module 10 uses a polymer lithium battery, and the electrolyte uses a solid or colloidal polymer material, which greatly reduces the weight of the acquisition device. At the same time, the unit energy is increased by 10% compared with the general lithium electronic battery, and its capacity, cycle life and other aspects are greatly improved.

[0035] like Figure 2 As shown, in this embodiment, the handheld housing 101 is a gun-type housing with a handle to facilitate holding and improve the user experience. Figure 3As shown, in this embodiment, the RFID acquisition module 1, the infrared acquisition module 2, the optical scanning module 3 and the laser ranging module 8 are respectively arranged at the muzzle of the gun-type housing, and a switch 103 is provided at the trigger of the gun-type housing, and the power module 10 is connected to the power supply end of the processor module 5 through the switch 103. When using the acquisition device of this embodiment, the user points the muzzle of the handheld housing 101 toward the target and presses the switch 103 at the trigger. After the processor module 5 is powered on, each functional module can be enabled to collect physical ID information, positioning information and positioning correction information.

[0036] In this embodiment, the terminal device 102 can be a smart device such as a mobile phone or a tablet computer. The terminal device 102 receives the physical ID and location information of the collected target objects such as metering devices, meter boxes, power poles, power transformers and other assets and materials through the communication module 7 and displays them.

[0037] In order to facilitate the operator to easily read the information on the terminal device 102 while operating the collection device, such as Figure 2 and Figure 3 As shown, in this embodiment, a clamping assembly 104 with an adjustable angle is installed on the handheld housing 101 to clamp the terminal device 102 .

[0038] In this embodiment, the clamping assembly 104 is in the form of a mobile phone back clip, such as Figure 2 and Figure 3 As shown, it includes a base 201, a first clamping member 202 and a second clamping member 203. The base 201 and the handheld housing 101 are hinged, the first clamping member 202 and the base 201 are fixedly connected, the vertical portion of the first clamping member 202 and the vertical portion of the second clamping member 203 are interconnected by a telescopic rod, and a gap for clamping the terminal device 102 is formed between the bent portion of the first clamping member 202 and the bent portion of the second clamping member 203.

[0039] like Figure 2 As shown, in this embodiment, a ball head 301 is provided at the end of the base 201, and a ball socket is correspondingly provided at the top of the handheld housing 101, and the ball head 301 is embedded in the ball socket to enable the clamping assembly 104 to be turned to any angle.

[0040] The following is a description of the working process of the physical ID and positioning information collection device of this embodiment:

[0041] First, switch to the physical ID collection equipment mode. After selecting one of the three collection methods, collect the ID numbers of physical assets such as on-site metering devices, meter boxes, power poles, power transformers, etc. and search and match them with the State Grid intranet system archives to query the corresponding physical asset details, and then use the RTK differential positioning method to send the positioning information of this physical asset to the information terminal (mobile phone, tablet computer, etc.). If the RTK differential positioning information is greater than a certain threshold from the positioning point coordinates in the original physical asset details, the physical asset model positioning information is updated in real time. Specifically, if Figure 5 As shown, the following steps are included:

[0042] S101) After the processor module 5 is powered on, an enable signal is sent to the RFID acquisition module 1, the infrared acquisition module 2, the optical scanning module 3, the positioning module 4, the laser ranging module 8 and the three-axis accelerometer 9 respectively;

[0043] S102) the processor module 5 waits for and obtains the physical ID information returned by the RFID acquisition module 1 or the infrared acquisition module 2 or the optical scanning module 3, and obtains the positioning information returned by the positioning module 4 (referred to as the first positioning information in this embodiment for distinction), and the positioning correction information returned by the laser ranging module 8 and the three-axis accelerometer 9;

[0044] S103) the processor module 5 corrects the first positioning information according to the positioning correction information, and then sends the corrected positioning information (referred to as the second positioning information in this embodiment for distinction) and the physical ID information to the terminal device 102 through the communication module 7; or, the processor module 5 sends the first positioning information, the positioning correction information and the physical ID information to the terminal device 102 through the communication module 7, and the terminal device 102 corrects the first positioning information according to the positioning correction information;

[0045] S104) After the terminal device 102 obtains the physical ID information, it matches the database to obtain the corresponding positioning information of the on-site metering device, meter box, power pole tower, power transformer, etc. (referred to as the third positioning information in this embodiment for distinction). If the second positioning information is inconsistent with the third positioning information, the corresponding third positioning information in the database is updated to the second positioning information.

[0046] Before step S101 of this embodiment, the operator selects the corresponding module from the RFID acquisition module 1, the infrared acquisition module 2, and the optical scanning module 3 by toggling the paddle switch of the multi-way selection module 6 according to the required acquisition method, and then points the muzzle of the handheld shell 101 toward the target and presses the switch 103 at the trigger to power on the processor module 5.

[0047] Since at least two modules among the RFID acquisition module 1, the infrared acquisition module 2, and the optical scanning module 3 cannot respond to the processor module 5 due to power failure, in order to avoid the processor module 5 not receiving a response for a long time after sending an enable signal to the RFID acquisition module 1, the infrared acquisition module 2, and the optical scanning module 3, in step S101 of this embodiment, after the processor module 5 is powered on, it can also first traverse the RFID acquisition module 1, the infrared acquisition module 2, the optical scanning module 3, the positioning module 4, the laser ranging module 8, and the three-axis accelerometer 9 to perform a communication test, and select the module that has successfully tested to send an enable signal. The specific steps of the communication test are well known to those skilled in the art, and the specific implementation project will not be repeated here.

[0048] In addition, it is also possible to consider using the same IO port of the processor module 5 to connect the RFID acquisition module 1, the infrared acquisition module 2, and the optical scanning module 3. The enable signal sent by the IO port will be input into the RFID acquisition module 1, the infrared acquisition module 2, and the optical scanning module 3 at the same time, and one of these three modules is always powered on, so it can be guaranteed that the enable signal sent by the processor module 5 will definitely be responded to.

[0049] In this embodiment, the positioning module 4 selects the RTK differential positioning method in the Beidou satellite system for positioning. First, the acquisition device receives the signal transmitted by the Beidou satellite through the receiving antenna, and solves the rough coordinates of the single point through the RTK module of the positioning module 4 to obtain the rough coordinates X0, Y0, Z0, and transmits the rough coordinate data to the terminal device 102 through the communication module 7. After the terminal device 102 receives the rough coordinates, it forwards the rough coordinates to the power Beidou platform. The Beidou platform combines the Beidou base station data and performs differential operations to solve the coordinates X1, Y1, Z1 of the acquisition terminal with centimeter-level accuracy. While obtaining the rough coordinates, the processor module 5 will send a distance measurement instruction and an angle measurement instruction to the laser ranging module 8 and the three-axis accelerometer 9. After receiving the instruction, the laser ranging module 8 will measure the distance S from the acquisition device to the acquisition target object. After receiving the instruction, the three-axis accelerometer 9 will measure the three-axis deflection angle θ of the acquisition device. x ,θ y ,θ z , and then the processor module 5 performs secondary correction calculation on the coordinates X1, Y1, and Z1 of the acquisition device to obtain the precise coordinates X2, Y2, and Z2 of the target object. Therefore, in step S103, when the processor module 5 corrects the first positioning information according to the positioning correction information, it includes:

[0050] S201) the processor module 5 sends the rough coordinates in the first positioning information to the terminal device 102 through the communication module 7, and the terminal device 102 forwards the rough coordinates to the differential positioning platform;

[0051] S202) The differential positioning platform performs differential calculation on the rough coordinates in combination with the reference station data to calculate the actual coordinates of the acquisition device;

[0052] S203) The differential positioning platform sends the actual coordinates of the acquisition device to the processor module 5 through the terminal device 102 and the communication module 7 in sequence;

[0053] S204) The processor module 5 performs correction calculation on the actual coordinates of the acquisition device according to the positioning correction information to obtain the actual coordinates of the target object. Specifically, the positioning correction information includes the distance S between the acquisition device and the target object and the three-axis deflection angle θ x ,θ y ,θ z , the actual coordinate expression of the target object is as follows:

[0054] X2=X1+S*cosθ x

[0055] Y2=Y1+S*cosθ y

[0056] Z2=Z1+S*cosθ z

[0057] Among them, X2, Y2, and Z2 are the coordinate values ​​of the target object respectively, and X1, Y1, and Z1 are the coordinate values ​​of the acquisition device respectively.

[0058] The steps for the terminal device 102 to correct the first positioning information according to the positioning correction information are basically the same. The difference is that after the terminal device 102 obtains the actual coordinates of the acquisition device sent by the differential positioning platform, it will not send it to the processor module 5 again, but waits for and obtains the positioning correction information, and then corrects the actual coordinates of the acquisition device according to the positioning correction information to obtain the actual coordinates of the target object.

[0059] In summary, the utility model discloses a method and device for collecting physical ID and precise positioning information of power grid assets and materials based on six methods, namely optical scanning, infrared communication, RFID radio frequency identification, laser ranging, RTK differential positioning, and three-axis acceleration sensor measurement, which is convenient and fast to read physical ID information and has high positioning accuracy. By combining optical scanning, infrared communication, and RFID radio frequency identification to collect data of physical ID, the precise positioning information of the collection equipment can be obtained through the positioning module based on RTK differential positioning, and the positioning information of the collection equipment can be corrected through the results of laser ranging and three-axis acceleration sensor measurement, so that the precise collection of physical ID information and geographic location information of assets and materials such as metering devices, meter boxes, power poles, and power transformers can be realized quickly and accurately, ensuring that the on-site equipment or materials are completely consistent with the system archives, and realizing cross-departmental and cross-professional data sharing and business integration in the power system.

[0060] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as a preferred embodiment, it is not used to limit the utility model. Therefore, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model shall fall within the scope of protection of the technical solution of the utility model.
