In the detailed description of the preferred embodiments that follow, reference is made to the accompanying drawings that form a part of the invention. The accompanying drawings illustrate, by way of example, specific embodiments The exemplary embodiments are not intended to be exhaustive of all embodiments in accordance with the invention. It is to be understood that other embodiments may be utilized and structural or logical modifications may be made without departing from the scope of the invention. Therefore, the following detailed description is not to be construed as limiting the scope of the invention.

Figure 1 shows a schematic diagram of a fixed asset inspection device in accordance with one embodiment of the present invention. The fixed asset inspection system shown in FIG. 1 includes an antenna 110, a reader 120, a server 130, a camera device 140, a position determining device 150, a distance measuring device 160, and a photometric device 170. It will be understood by those skilled in the art that only the network elements necessary for understanding the present invention are shown in FIG. 1. Other network elements, such as other antennas, readers, and camera devices, may also be included in the fixed asset inspection system.

Antenna 1 10 is configured to transmit a radio frequency signal to an electronic tag and receive a radio frequency signal from the electronic tag. Here, according to national regulations, the transmission power of the radio frequency signal cannot exceed 2w. In order to realize long-distance signal transmission and reception at such a low transmission power, the size of the antenna 110 can be designed to be 20-50 cm.

In an embodiment in accordance with the invention, the frequency band of antenna 1 10 is

902-928MHZ, in another embodiment according to the present invention, the frequency band of the antenna 1 10 is 865-868 MHz, and those skilled in the art can understand that the frequency band of the antenna can also be other frequency bands that can be realized.

In one embodiment in accordance with the invention, antenna 1 10 has a gain of 6-19dBi; a dimension of 445*445*40 mm; a vertical plane half power angle of 31-68 degrees; and a horizontal half power angle of 40-65 degrees. The radome material is polycarbonate and acrylonitrile-butadiene-styrene copolymer and mixture (ABS PC ). Those skilled in the art will appreciate that the parameters given herein are merely exemplary. Those skilled in the art will be able to employ other possible parameters without departing from the basic idea of the invention.

A reader 120 is electrically coupled to the antenna 1 10 to instruct the antenna to transmit a radio frequency signal or to receive a signal received by the antenna. And the reader is configured to identify information recorded in the chip based on the received signal based on radio frequency identification technology. Here, the specific manner of identifying the content recorded in the chip based on the radio frequency identification technology will not be described again. Further, the information recorded in the chip includes identification information related to the fixed asset, and may also include other information related to the fixed asset such as location information. The reader can also be used to write the above information to the chip.

In one embodiment in accordance with the present invention, the reader 120 is compatible with the EPC C1 Gen2/ISO 18000-6C protocol standard and has an RF output power of +10 dBm to +32.5 dBm (external power supply). Similarly, those skilled in the art will understand that The parameters given here are also merely exemplary.

A server 130, which is electrically coupled to the reader 120, receives the information it recognizes from the reader 120. Also electrically connected to the server 130 are a camera unit 140, a position determining unit 150, a distance measuring unit 160, and a photometric unit 170.

Those skilled in the art can understand that the camera device 140 and the position determining device

150. Ranging device 160 and photometric device 170 are not essential to the implementation of the present invention because, even without such devices, server 130 can communicate with fixed assets stored in server 130 by information recognized by reader 120. The associated identification information is matched to determine the existence of the fixed asset.

That is, in an embodiment where the fixed asset inspection system includes only the antenna 110, the reader 120, and the server 130, the read fixed asset inspection system can only identify the presence of fixed assets stored in the server. Those skilled in the art will appreciate that the fixed asset inspection system may also include an output device, such as a speaker, that outputs a beep if a fixed asset is missing. The output device can also be a display to display the inspection results on the display for inspection by the inspection personnel.

In an embodiment where the fixed asset inspection system further includes a camera device 140, a position determining device 150, and a distance measuring device 160, the server 130 can send a camera command to the camera device 140, indicating the shutter time, and receiving the captured fix from it. An image of the asset.

Here, the shutter timing can be determined by the server 130 based on the location information about the fixed assets stored in the server 130 and the current location determined by the location determining means 150. For example, when the server judges that the position of the fixed asset is within a certain distance from the front according to the current moving direction, the camera is instructed to open the shutter and record an image. The shutter time can also be determined by the matching result of the information recognized by the server 130 based on the reader 120 and the identification information associated with the fixed asset stored in the server 130. That is, when the server 130 confirms that the existence of the fixed asset has been recognized, and it is necessary to further judge the integrity thereof, the photographing device 140 is instructed to open the shutter and record an image.

The server 130 compares the image of the fixed asset captured by the camera device 140 with the image information related to the fixed asset stored in the server 130, thereby determining the integrity of the fixed asset. Specifically, the server 130 captures real time according to the camera device 140. The image is combined with an image pattern recognition algorithm to determine the integrity of the fixed asset. For example, whether the reflective film of the sign is complete is determined based on whether the text indicated on the road sign can be identified.

The server 130 is also able to obtain from the location determining device 150 the information it has obtained regarding the current location. For example, in an embodiment in accordance with the present invention, the position determining device 150 is a Global Positioning System (GPS) based device that is always turned on when the patrol system is in operation to obtain a current position. The information is the current GPS coordinates.

The server 130 is also capable of obtaining the distance between the measured ranging device and the fixed assets from the ranging device 160. Within the allowable error range (e.g., lm or 0.5m), the position of the position determining device and the position of the distance measuring device can be considered to be the same. Thus, the server can determine the location of the fixed asset based on the above two pieces of information. And the server 130 stores location information related to the fixed asset. For example, in an embodiment in accordance with the present invention, the location determining device 150 is a GPS-based device, and the electronic map in the server records the outdoor fixed assets of the entire network. GPS location (such as equipment, signage). In other embodiments, only the location of the fixed asset associated with the patrol segment is stored in the server. The server 130 can compare the determined location of the fixed asset with the location information about the fixed asset stored in the server 130 to determine whether the location of the fixed asset is correct.

In addition, the server 130 is also capable of obtaining the intensity of the reflected light from the surface of the fixed asset that it recognizes from the photometric device 170. In one embodiment in accordance with the invention, the surface of the fixed asset has a reflective material, such as a reflective film. The eligibility of the reflective material can be checked at night using the automatic inspection system in accordance with the present invention. Specifically, the illumination lamp of the vehicle or the illumination lamp provided by the photometric device illuminates the surface of the fixed assets and is reflected by the reflective material on the surface of the fixed assets. The server 130 can judge the eligibility of the reflective material based on the light intensity information recognized by the photometric device 170. For example, when the light intensity is greater than a predetermined threshold, the reflective material is considered to be acceptable, otherwise the aging of the reflective material reaches a level that needs to be replaced.

In the embodiment shown in Figure 1, the fixed asset inspection system is placed in the vehicle In the execution of the inspection of the fixed assets, the vehicle can travel on the road in the direction prescribed by the traffic rules. The fixed asset inspection system according to the present invention can work normally at a speed of up to 80 km/h, thereby reducing the risk of driving at a lower speed on a highway for the inspection of fixed assets. .

In other embodiments in accordance with the invention, the fixed asset inspection system can also be placed on a vessel in which the vessel is traveling in the direction specified by the traffic regulations. It can automatically check the fixed assets on the route.

Figure 2 shows a schematic representation of a fixed asset constructed in accordance with one embodiment of the present invention.

As shown in Figure 2, the fixed assets include the fixed asset body 210 and the electronic tag.

220. Among them, the electronic tag 220 further includes a chip based on radio frequency identification technology, a peripheral circuit, and a tag antenna. In the embodiment shown in FIG. 2, the fixed asset body 210 can be a traffic sign on a highway, a traffic signal device, an electronic camera device, a billboard, a street light, or an emergency telephone, among other fixed assets that can be conceived by those skilled in the art. In other embodiments, the fixture can also be a shipping marker, an electronic camera, or the like on an inland or marine channel.

In a specific embodiment, the electronic tag 220 has a gain of 1-19 dBi; complies with the ISO18000-6C (EPC) protocol; operates in the frequency range of 860 to 960 MHz; and the tag antenna material is copper foil, aluminum foil or graphene. Those skilled in the art will appreciate that the parameters given herein are merely exemplary. Those skilled in the art will be able to employ other possible parameters without departing from the basic idea of the invention.

For a fixed asset 210 across the lane, such as a traffic signage, a traffic signal device, an electronic camera, the electronic tag 220 is attached to the surface of the fixed asset body 210 and faces in the direction of the vehicle of the lane so as to be placed in the vehicle The fixed asset inspection system in the middle can recognize the electronic tag 220. In addition, the electronic tag 220 is packaged with a sealed waterproof material.

For fixed assets 210 placed next to the lane, such as an emergency call. The electronic tag 220 is attached to the direction of the vehicle of the fixed asset 210 facing the lane, so that the fixed asset inspection system disposed in the vehicle can recognize the RFID in the read electronic tag. chip.

In another embodiment, the fixed asset is a fixed asset located in an inland river or sea lane, such as a shipping marker, an electronic camera, or the like.

In one embodiment, the electronic tag 220 also includes a power source and tilt warning device (not shown). In the case of a fixed asset tilt, the fixed asset inspection system may not be able to properly read the electronic tag. The tilting alarm provided in the electronic tag will recognize the tilt of the tag and actively send an alarm message through the antenna when the tilt exceeds a predetermined threshold, so that the inspecting device can recognize the tilt of the fixed asset.

The following describes the working mode of the system according to the present invention by taking the automatic inspection of the fixed assets of the expressway as an example.

Highway fixed assets mainly include signs, signs and attached brackets. These assets are made of metal, so theft often occurs. Once the theft occurs, it not only causes huge economic losses to the enterprise, but also has a major impact on road safety and becomes a safety hazard that cannot be ignored.

The inspection of the fixed assets of the expressway is to check whether the signage is lost. Second, it is necessary to confirm the integrity of the signage, such as whether it is tilted, whether the reflective film is damaged, whether it is obscured, and the degree of aging. The traditional manual mode inspection requires visual observation. For example, if the gantry frame crosses the highway sign bracket, there will be as many as 4 to 5 large signs in a row. It takes a long time to confirm by visual observation. The integrity of the signage requires a reduction in speed to complete the job. As we all know, driving at low speed on the main highway is a very dangerous thing.

Since the processing speed of the radio frequency identification technology is on the order of leap seconds, the fixed asset automatic inspection system proposed by the present invention can automatically inspect the fixed assets under the condition that the inspection vehicle runs at a high speed. Moreover, the pattern recognition of the captured image does not require manual intervention and is automatically recognized by the computer.

Figure 4 illustrates a method flow diagram in accordance with one embodiment of the present invention.

In method step S401, the location determining means 150 determines the current location and transmits the determined current location to the server 130 in method step S402. Optionally, the distance measuring device 160 determines its distance from the fixed asset in method step S403, The determined current location is sent to the server 130 in method step S404. The server 130 compares the current location with the location information about the fixed asset stored in the server 130 in method step S405. If it is determined that the patrol device is approaching a certain fixed device, a read command is sent to the reader 120 in method step S406. In method step S407, the reader 120 transmits a radio frequency signal via the antenna and receives feedback information of the electronic tag attached to the surface of the fixed asset in response to the iH reading instruction. For example, when the inspection system is 40 50 meters away from the fixed assets, the electronic tag on the surface of the fixed asset enters the electromagnetic field of the RF signal of the reader, receives the RF signal from the antenna, and sends the product information stored in the chip by the energy obtained by the induced current. (passive tag or passive tag), or the tag actively sends a signal of a certain frequency (active tag or active tag), after the reader reads the information and decodes it, the method transmits the identified information to the server in method step S408. .

Optionally, after the patrol vehicle passes the target object a certain distance, the server 130 sends a signal to the reader 120 to turn off the transmission of the radio frequency signal regardless of whether or not the electronic tag receives the response. This enables intermittent transmission of RF signals, mitigating possible RF interference to other systems, and saving energy. In the time period during which the radio transmission is turned on, if the reader does not receive a response to the electronic tag that is supposed to be present, it indicates that the target object no longer exists.

In method step S409, the server 130 determines that the fixed asset is identified by matching the identification information identified by the reader 120 with the identification information associated with the fixed asset stored in the server 130.

Optionally, the server 130 records the real-time GPS coordinates, and determines the location of the fixed assets by the distance measured by the distance measuring device from the fixed assets. And by comparing the GPS coordinates stored in the server 130, it is determined whether the target object of the inspection is consistent with the original position.

This application is important. For example, in the channel identification tour, the channel mark will drift due to bad weather and hydrological influences. This problem can be found by the automatic inspection system combined with the global positioning system.

In method step S410, the reader 120 sends a photo finger to the camera device 140. Let, instruct the camera device 140 to capture an image of the fixed asset. In this embodiment, the shutter timing is after it is determined that the fixed asset is identified. Those skilled in the art will appreciate that this is not required and that the shutter moment can also be prior to identifying the fixed asset.

In method step S411, camera unit 140 opens the shutter to capture an image of the fixture. Alternatively, the focal length of the camera unit 140 can be adjusted based on the distance measured by the distance measuring device 160 from the fixed assets. The distance information can be provided directly to the camera device 140 by the ranging device 160 or provided to the camera device 140 by the server 130.

In method step S412, the camera device 140 transmits the image information to the server, which in turn, in accordance with the pattern recognition algorithm in method step S413, extracts the features of the signage in the image and associates it with the sign stored in the server 130. The characteristics are matched to determine the integrity of the fixed asset. If the match reaches a certain degree of similarity, it is considered that there is no problem in the complete '1' of the signage, and no 'J thinks that the signage has a potential problem and is recorded in the inspection report automatically generated by the server.

It will be understood by those skilled in the art that the inspection process described in connection with FIG. 4 is only an example and is not intended to limit the scope of the invention. Those skilled in the art can reasonably change the order of the steps in Figure 4, or delete some of the steps to achieve automatic inspection of fixed assets.

It is apparent to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, in any case, the embodiments should be considered as exemplary and non-limiting. In addition, it is obvious that the word "comprising" does not exclude other elements and steps, and the word "a" does not exclude the plural. The plurality of elements recited in the device claims can also be implemented by one element. The words first, second, etc. are used to denote names and do not denote any particular order.
