Referring to fig. 2, a schematic diagram of an addressing system for UWB anchor points according to an embodiment of the present invention, which is applied to a vehicle, includes a host node and a plurality of anchor points. In other embodiments, the addressing system may be applied to other devices using UWB location technology.
Referring to fig. 2, the plurality of anchor points include a first anchor point located at a front left corner of the vehicle, a second anchor point located at a rear left corner of the vehicle, a third anchor point located at a front right corner of the vehicle, a fourth anchor point located at a rear right corner of the vehicle, and a fifth anchor point located at a middle portion of the vehicle. The master node is communicatively connected to the first to fifth anchor points, in this embodiment, via a CAN bus, and in some other implementations, via other communication buses known to those skilled in the art. The main node is connected to a battery, supplies power to the fifth anchor point through a first power supply, supplies power to the first anchor point and the second anchor point through a second power supply, and supplies power to the third anchor point and the fourth anchor point through a third power supply. The first to third power supply sources may be three power supply ports on the master node, or may be three separate power supply circuits on the master node. Accordingly, for the first to fifth anchors of the present embodiment, there are only four pins each thereon, i.e., one power supply pin, one ground pin, and two communication bus pins (CAN _ H and CAN _ L in the present embodiment). It should be noted that the number and the positions of the anchor points in this embodiment are only examples, and those skilled in the art may set different numbers of anchor points at different positions as needed.
Referring to fig. 3, the addressing system of the present embodiment performs addressing based on the following addressing method:
first, the correspondence between the anchor codes and the power information and/or the distance information is stored in each anchor.
Specifically, after the vehicle is designed and finalized, the positions of the host node and each anchor point on the vehicle are determined, that is, the distance between the host node and each anchor point is determined, and the power supply through which each anchor point supplies power is also determined, so that it is necessary to define the code of each anchor point on the vehicle and store the correspondence between the code of each anchor point and the power supply information and/or the distance information (the distance between each anchor point and the host node) in each anchor point (or in the host node at the same time). It should be noted that each anchor point herein refers to all anchor points that need to be addressed. In the present embodiment, the codes defining the first to fourth anchor points located at the four corners of the vehicle are 1, 2, 3, and 4, respectively, and the code defining the fifth anchor point located inside the vehicle is 5. In some other embodiments, the codes of the first to fourth anchor points may be defined as 5, 4, 3, and 2, respectively, and the code of the fifth anchor point inside the vehicle may be defined as 1, it should be noted that the specific code value of each anchor point may be flexibly set by those skilled in the art as needed, and the specific numerical values mentioned in this application are only examples, and are not limitations of this application. In the present embodiment, the first power supply supplies power only to the fifth anchor point, and there is a one-to-one correspondence relationship between the first power supply and the fifth anchor point, and therefore, the correspondence relationship between the code 5 and the power supply information (i.e., the first power supply) is stored in each of the anchor points (the first to fifth anchor points). The second power supply supplies power to the first anchor point and the second anchor point, the linear distance from the first anchor point to the main node is 3 meters, and the linear distance from the first anchor point to the main node is 5 meters, so that the corresponding relation between the code 1 and the power supply information (i.e., the second power supply) and the distance information (in this embodiment, the distance information is stored in a distance range including 3 meters, for example, 2.5-3.5 meters) is stored in each anchor point, and the corresponding relation between the code 2 and the power supply information (i.e., the second power supply) and the distance information (in this embodiment, the distance information is stored in a distance range including 5 meters, for example, 4.5-5.5 meters) is stored in each anchor point. Similarly, the third power supply supplies power to the third anchor point and the fourth anchor point, the linear distance from the third anchor point to the host node is 3 meters, the linear distance from the fourth anchor point to the host node is 5 meters, the correspondence between the code 3 and the power supply information (i.e., the third power supply) and the distance information (in this embodiment, the distance information is stored in a distance range including 3 meters, for example, 2.5 to 3.5 meters) is stored in each anchor point, and the correspondence between the code 4 and the power supply information (i.e., the second power supply) and the distance information (in this embodiment, the distance information is stored in a distance range including 5 meters, for example, 4.5 to 5.5 meters) is stored in each anchor point. It should be noted that, when the first to fifth anchor points are installed on the vehicle, their codes are all default values, for example, 0, and although we define the code corresponding to each anchor point, each anchor point cannot be determined at the time of installation, and needs to be addressed after installation.
Then, each anchor point identifies the power supply of the anchor point and determines the code corresponding to each anchor point according to the corresponding relation; or, each anchor point obtains the distance between the anchor point and the main node or a preset anchor point, and determines the code corresponding to each anchor point according to the corresponding relation; or, each anchor point identifies the power supply and obtains the distance between the anchor point and the main node or a preset anchor point, and the code corresponding to each anchor point is determined according to the corresponding relation. It should be noted that each anchor point referred to herein may refer to all anchor points, or may refer to one or more anchor points among all anchor points.
Specifically, in this embodiment, after the host node is powered on for the first time, or after an addressing request sent by the OBD diagnostic apparatus is received through the CAN bus, the host node supplies power to the fifth anchor point through the first power supply source, the fifth anchor point receives power and then receives a bus signal (in this embodiment, the CAN bus), the bus signal includes information of a power supply that supplies power to the fifth anchor point, the fifth anchor point reads the information from the bus signal, and thus recognizes that the power supply that supplies power to the fifth anchor point is the first power supply source, and then determines that the code of the fifth anchor point is 5 according to a correspondence between a pre-stored code and power supply information (the code 5 corresponds to the first power supply source), and stores the code, that is, the code 5 is modified by the default code 0, so that the subsequent positioning function operates according to the new code 5. For example, the fifth anchor point may carry its own code 5 when transmitting information to the master node, so that the master node may know that the information is transmitted by the fifth anchor point located in the vehicle after receiving the information.
The main node supplies power to the first anchor point and the second anchor point through a second power supply. The first anchor point and the second anchor point recognize that the power supply supplying power to the first anchor point and the second anchor point is the second power supply, and the specific mode of recognizing the power supply is similar to that of the fifth anchor point, and the details are not repeated here. Since the first and second anchor points share one power supply, they cannot be distinguished only by the power supply. Therefore, the main node sends out UWB ranging requests to the first anchor point and the second anchor point; the first anchor point and the second anchor point receive the UWB ranging request, and respectively acquire the distance between the first anchor point and the main node according to the flight time of UWB signals, for example, the distance information acquired by the first anchor point to the main node is 3.1 meters; the distance between the second anchor point and the main node is 5.1 meters when the second anchor point is acquired. Since 3.1 meters belongs to the preset distance range of 2.5-3.5 meters, the first anchor point can determine that the corresponding code is 1 according to the corresponding relation between the pre-stored code and the power information and the distance information (the code 1 corresponds to the second power supply and the distance of 2.5-3.5 meters), and the first anchor point stores the code 1 and uses the code in the subsequently sent information. Correspondingly, since 5.1 meters belongs to the preset distance range of 4.5-5.5 meters, the second anchor point can determine that the corresponding code is 2 according to the corresponding relationship between the pre-stored code and the power information and the distance information (the code 2 corresponds to the second power supply and the distance of 4.5-5.5 meters), store the code 2 and use the code in the subsequently sent information.
The third and fourth anchors, similarly to the first and second anchors, also confirm their codes as 3 and 4, respectively, and store them in the same manner as described above.
Therefore, compared with the prior art, the technical scheme of the embodiment can realize the addressing of each anchor point without using the coding PIN and the corresponding wire harness, and each UWB anchor point can save 3 coding PIN feet and the corresponding wire harness, so that the wire harness of the whole vehicle is greatly reduced, and the difficulty of vehicle wiring is remarkably reduced. Meanwhile, after the UWB anchor point saves 3 PIN feet, the UWB anchor point can be smaller in size, can be adapted to more types of vehicles, and reduces development cost and time.
Further, in this embodiment, the addressing system further includes four radars (first to fourth radars), each radar is disposed near an anchor point and is in communication connection with the anchor point (the first to fourth radars are in communication connection with the first to fourth anchor points, respectively), the corresponding anchor point sends its code to the corresponding radar through digital signal communication, and the corresponding radar may generate its code based on the code of the anchor point, for example, add a prefix or a suffix to the code of the anchor point. Accordingly, the corresponding radar also does not need to use a coded PIN, so that the wiring harness of the vehicle can be greatly reduced. In other embodiments, the radar may be replaced by other sensors disposed near the anchor point.
In other embodiments, the master node supplies power to each anchor point through different power supply sources, and each anchor point has a one-to-one correspondence relationship with the power supply. Therefore, only the correspondence between the codes and the power supply information is stored in each anchor point. And identifying the power supply of each anchor point on the vehicle, and determining and storing a corresponding code according to the corresponding relation between the code and the power supply information.
In other embodiments, the master node is at different distances from each anchor point on the vehicle, such that the master node may supply power to each anchor point from only one power supply. Accordingly, each anchor point stores only the correspondence between the code and the distance information (the distance range between each anchor point and the master node). The main node sends out UWB ranging request to each anchor point; and each anchor point receives the ranging request, respectively acquires the distance between the anchor point and the main node according to the flight time of the UWB signals, and determines and stores the corresponding codes according to the pre-stored corresponding relation.
In other embodiments, a predetermined anchor point on the vehicle may be located at a different distance from other anchor points, such that the master node may only supply power to each anchor point from one power supply. Thus, each anchor point stores only the correspondence between the code and the distance information (the distance range between the preset anchor point and each of the other anchor points). The preset anchor point sends out UWB ranging requests to other anchor points; and other anchor points receive the ranging request, respectively acquire the distance between the ranging request and the preset anchor point according to the flight time of the UWB signals, and determine and store corresponding codes according to the pre-stored corresponding relation.
It should be noted that the embodiments of the present invention have been described in terms of preferred embodiments, and not by way of limitation, and that those skilled in the art can make modifications and variations of the embodiments described above without departing from the spirit of the invention.
