All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

As mentioned in the background art, the present smart meter measuring system is affected by the power supply manner, and has a technical problem of poor power supply reliability, and the inventor has found through careful study that the above technical problem is caused by the fact that when a user uniformly supplies power to a plurality of smart meters through the same power supply line, the more the smart meters are connected to one power supply line, the larger the current on the power supply line, after the cables are selected, the cable resistance per unit length is fixed, so that the voltage drop generated on the cables per unit length becomes larger, especially for the smart meters installed at the rear end of the power supply line, the cable length of the corresponding power supply line becomes longer, and the voltage drop increase is further caused by the increase of the cable length, so that the voltage available to the smart meters installed at the rear end of the power supply line becomes smaller, when the cable of the power supply line is long to a certain extent, the situation that the voltage available to the smart meters is insufficient and the measurement work cannot be normally performed is caused, and the power supply reliability of the smart meter measuring system is poor.
Aiming at the technical problems, the invention takes a 3D radar as an example for explanation, and provides the following specific solutions:
fig. 1 is a schematic structural diagram of a 3D radar measurement system with reliable power supply according to an embodiment of the present invention. Referring to fig. 1, a 3D radar measurement system with reliable power supply includes a plurality of radar bodies 20, at least one boost module 30, and at least one power supply loop; each power supply loop extends from the head end to the tail end and is connected with the radar bodies 20, so that each power supply loop is shared by the radar bodies 20, and the voltage drop of each power supply loop is increased along with the increase of the extension length, so that a boosting module 30 is arranged in each radar body 20 meeting the preset boosting condition, and each boosting module 30 is used for boosting the input voltage of the corresponding radar body 20 and the radar body 20 at the rear end to the threshold voltage so as to enable the radar body 20 to work normally.
The radar body 20 in the 3D radar measurement system may be a 3D multi-point radar, a 3D microwave scanning radar, a 3D laser scanning radar, or the like. It is appreciated that the boost module 30 may be any boost circuit, such as an inductive DC/DC boost circuit.
It will be appreciated that the preset boost condition may be, but is not limited to being, near but not less than the input voltage of the radar body 20; the threshold voltage can be adaptively adjusted according to the actual application situation of the radar body 20, but the set threshold voltage is greater than or equal to the minimum input voltage that the radar body 20 can normally work.
In one implementation of the present embodiment, the radar body 20 includes a wiring portion such that the booster module 30 is disposed in the wiring portion. It is known that the connection portion of the radar body 20 may be specifically a junction box or a junction box.
In another implementation of the present embodiment, specifically, the head end of the power supply loop is connected to a power supply unit (not shown in fig. 1); the power supply unit provides electric energy and is connected with each radar body 20 through the same power supply loop, and is used for directly providing input voltage for the radar body 20 on the power supply loop; after the cable is selected, neglecting minor differences caused by temperature changes and the like, the resistivity of the cable and the cross-sectional area of the cable are known and are fixed, the resistance of the cable in unit length is fixed, and the larger the current on the cable, the more the voltage drop is generated by the cable in unit length.
The power supply unit can be a direct-current storage battery, an alternating-current to direct-current power supply module and the like.
It will be understood that, for the radar body 20 located at the end of the power supply loop, the head end position of the power supply loop (i.e. the position of the power supply unit), the installation position of the radar body 20 and the cable laying mode determine the cable length of the power supply loop corresponding to the radar body 20, the longer the cable length is, the larger the generated voltage drop will be, in addition, the more the radar bodies 20 are connected on the same power supply loop, the larger the current on the power supply loop will be, the further voltage drop will be increased, therefore, if the voltage boosting module 30 is not provided on the radar body 20, the input voltage of the radar body 20 at the subsequent stage is lower than the input voltage of the radar body 20 at the previous stage, the input voltage obtained by the radar body 20 at the previous stage is lower than the minimum input voltage that the radar body 20 can normally operate, when the input voltage of the radar body 20 is close to but not lower than the minimum operating voltage of the radar body 20, the voltage boosting module 30 is considered to be required to be introduced, and the voltage boosting module 30 is set in the corresponding radar body 20, and the input voltage of the radar body 20 and the radar body 20 at the subsequent stage is lifted. Therefore, the voltage boosting module 30 is arranged in the radar body 20 meeting the preset voltage boosting condition, so that the input voltage of the radar body 20 is raised to the threshold voltage, the radar body 20 can work normally, and the power supply reliability is ensured.
In the whole power supply loop, if the number of connected radar bodies 20 is enough, there may be a situation that one voltage boosting module 30 is arranged in the whole loop at intervals, and each voltage boosting module 30 is responsible for boosting the input voltage of the radar body 20 between the voltage boosting module 30 and the next voltage boosting module 30. In addition, a 3D radar measurement system may further have more than one power supply loop, and reliable power supply of each power supply loop may be set as described above, which is not described herein.
In summary, in this embodiment, a plurality of radar bodies are connected in the middle of each power supply loop extending from the head end to the tail end, so that each power supply loop is shared by a plurality of radar bodies, and the voltage drop of each power supply loop increases along with the increase of the extension length, so that a voltage boosting module is provided in each radar body meeting the preset voltage boosting condition, and each voltage boosting module is used for raising the input voltages of the corresponding radar body and the radar body at the rear end to the threshold voltage, so that the radar bodies work normally. Even if the radar body located at the tail end of the power supply loop is affected by factors such as the length of the power supply loop and the current of the power supply loop, and cannot obtain enough input voltage, each boosting module can raise the input voltage of the corresponding radar body and the radar body at the rear end to the threshold voltage, so that the radar body can work normally. Therefore, the embodiment can realize reliable power supply of the 3D radar, improves the power supply reliability of the 3D radar measurement system, and is beneficial to ensuring the measurement accuracy of the 3D radar measurement system.
It should be noted that fig. 1 exemplarily shows that the number of radar bodies 20 is 3, and the number of boost modules 30 is 1, which is not a limitation of the embodiment of the present invention.
On the basis of the above embodiment, fig. 2 is a schematic structural diagram of another 3D radar measurement system with reliable power supply according to an embodiment of the present invention, referring to fig. 2, optionally further including a central control terminal 40; the container 10 is provided with at least one radar body 20, and the central control end 40 is at least used for acquiring all measurement data of all radar bodies 20 in each detection period of each container 10 and removing abnormal measurement data in all measurement data so as to analyze the material level information of all the surfaces of the medium in the container 10 according to the effective measurement data of all the radar bodies 20 in each detection period of each container 10; and modeling and converting according to the material level information on each part of the surface of the medium to obtain the precise parameters of the medium, and displaying or outputting the precise parameters.
The precise parameters at least comprise a three-dimensional graph, a medium volume, a medium mass, a medium average height, a medium minimum height, a medium maximum height and coordinate values of points on the medium surface.
It is understood that the central control terminal 40 may refer to a central control system in the field; the time span of the detection period can be adaptively set according to the actual working condition of the site, for example, 1 hour, 12 hours, 1 day, 1 week, one month, etc. In addition, the radar body 20 may measure the internal obstacles (such as container walls, beams, material flows, heating coils, ladders, etc.) of the container 10, and the measurement accuracy of the radar body 20 may be seriously affected by the interference echo signals generated by the reflection of the measurement signals sent by the radar body 20 by the obstacles, so that the abnormal measurement data may be data obtained by measuring the internal obstacles of the container 10 by the radar body, and correspondingly, the effective measurement data is the remaining measurement data after the central control end 40 rejects the abnormal measurement data in all the measurement data.
Further, the level information may refer to information that the central control terminal 40 analyzes from the valid measurement data in each detection cycle and can represent the position of the medium surface throughout the container 10. Illustratively, when the morphology of the medium is solid and the surface of the medium is in the form of asperities, the highest height of the medium refers to the spatial position of the medium at the highest convexity in the container 10, and the lowest height of the medium refers to the spatial position of the medium at the lowest concavity in the container 10. Adaptively, the average media height may be an average of the sum of the highest media height and the lowest media height.
It will be appreciated that if a plurality of radar bodies 20 are disposed on a certain container 10, there is a possibility that any radar body 20 scans the medium surface scanned by other radar bodies 20 during operation, and at this time, the central control terminal 40 directly discards the repeated measurement data, which may result in resource waste. In view of this, the inventors creatively propose the following data processing modes of the central control terminal 40 to utilize the data resources of the radar body 20 to the greatest extent, which is beneficial to guaranteeing the accuracy of the measurement system.
In one implementation of this embodiment, optionally, when the number of radar bodies 20 installed on the container 10 is greater than 1, and there is an overlapping position in the measurement ranges of each radar body 20 in each detection period, the central control end 40 is specifically configured to average, weighted average, and trade-off according to the reliability, the valid measurement data corresponding to the overlapping position, so as to obtain precise level information of the medium in the overlapping position. The precise level information may be information that is obtained by averaging, weighted averaging, and resolving the effective measurement data corresponding to the overlapping positions by the central control terminal 40 according to the confidence score in each detection cycle, and is capable of indicating the surface position of the medium in the container 10.
In another implementation of the present embodiment, optionally, when the number of radar bodies 20 mounted on the container 10 is greater than 1, and there is no overlapping position of the measurement ranges of the respective radar bodies 20 in each detection cycle, the central control end 40 is specifically configured to directly integrate the effective measurement data of all the radar bodies 20 on the container 10 in each detection cycle, so as to obtain the precise parameters of the medium.
Therefore, the embodiment provides the 3D radar measurement system capable of simultaneously taking the power supply reliability, the measurement precision and the data resource utilization rate into consideration, and the data resource of the radar body is utilized to the greatest extent on the basis of realizing the reliable power supply of the 3D radar, so that the precision of the measurement system is guaranteed.
