[0071] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0072] The present application embodiment provides a data processing method, which is applied to a detection device, such as Figure 1 As shown, the method includes:
[0073] Step 101: At each of at least one detection point in a target area, based on receiving a signal sent by at least one RSU arranged in the target area, quality detection is performed on a signal sent by the at least one RSU to obtain a detection result related to signal quality;
[0074] Step 102: Send first information to the server; the first information includes the location of each detection point and the corresponding detection result; the first information is used to evaluate the deployment of the RSU.
[0075] In actual application, the target area can be set according to demand, such as a parking lot, a business district, a section of highway, etc.
[0076] In actual application, the detection point may also be called a test point, a monitoring point, etc. The embodiment of the present application does not limit the name of the detection point.
[0077] In actual application, the detection equipment may also be called a detection device, etc. The embodiment of the present application does not limit the name of the detection equipment, as long as the function of the detection equipment can be achieved.
[0078] In actual application, the detection device can be set on a vehicle and move with the vehicle in the target area to perform quality detection on the signal sent by the at least one RSU at each detection point; or, the detection device itself can have the ability to move.
[0079] In actual application, the communication mode between the detection device and the RSU can be set according to the requirements. For example, the detection device can communicate with the RSU based on the PC5 interface. In addition, the signal sent by the RSU can be called an RSU signal, a PC5 signal, an RSU-PC5 signal, etc., which is not limited in the embodiment of the present application.
[0080] In actual application, the detection device may receive a signal sent by at least one RSU at each detection point. Due to the different locations of the detection points, the RSU signal received by the detection device at each detection point may be sent by the same or different at least one RSU. In addition, if the detection device does not receive a signal sent by the RSU at a detection point, the corresponding detection result may be set to 0.
[0081] In actual application, the position of each of the at least one detection point can be fixed, that is, pre-set according to needs; or, the detection device can periodically detect its own position during the movement within the target area, and determine the detected position as the position of a detection point, wherein the period for the detection device to detect its own position can be set according to needs, and periodic detection can also be understood as real-time detection (i.e. monitoring); or, the detection device can detect its own position when receiving a signal sent by the RSU during the movement within the target area, and determine the detected position as the position of a detection point.
[0082] Here, the specific method of determining the position of the detection point by the detection device can be set according to the needs, and the embodiment of the present application does not limit this. In addition, the format of the position of each detection point can also be set according to the needs, such as longitude and latitude coordinates, relative position coordinates with a specific position, etc.
[0083] In step 101, in actual application, the specific content included in the detection result related to signal quality can be set according to requirements.
[0084] Based on this, in one embodiment, the performing quality detection on the signal sent by the at least one RSU may include:
[0085] For a signal sent by each RSU in the at least one RSU, a signal strength (ie, signal reception strength), a transmission delay, a bit error rate, and a first distance are determined; the first distance represents a distance between a corresponding detection point and a corresponding RSU.
[0086] Accordingly, the detection result includes the signal strength, transmission delay, bit error rate and first distance corresponding to each RSU in at least one RSU. It can be understood that the detection result can reflect the number of RSUs that the detection device can communicate with at the corresponding detection point. Exemplarily, the detection result includes at least one RSU identifier (such as a number) and the signal strength, transmission delay, bit error rate and first distance corresponding to each RSU identifier.
[0087] In actual application, in addition to the signal strength, the detection device can also perform other transport layer performance tests on the signal sent by each RSU in the at least one RSU, such as determining the decoding success rate, the number of message packets received, etc.; accordingly, the detection result can also include the decoding success rate, the number of message packets received and other transport layer performance test results corresponding to each RSU in the at least one RSU.
[0088] In actual application, in addition to the transmission delay and the bit error rate, the detection device can also perform other service layer performance tests on the signal sent by each RSU in the at least one RSU, such as determining the transmission packet loss rate, information reception integrity, etc.; accordingly, the detection result can also include the service layer performance test results such as the transmission packet loss rate and information reception integrity corresponding to each RSU in the at least one RSU.
[0089] In step 102, in actual application, after obtaining a detection result related to the signal quality at each detection point, the detection device may associate the position of the corresponding detection point with the corresponding detection result to obtain the first information.
[0090] In actual application, sending the first information to the server may include:
[0091] The first information is periodically sent to the server.
[0092] Here, the specific period of the detection device sending the first information to the server can be set according to demand. In addition, periodically sending the first information can also be understood as sending the first information in real time. In other words, the detection device sends the location of the detection point and the corresponding detection result to the server in real time.
[0093] In actual application, the detection device can detect the vehicle speed, that is, the moving speed of the detection device, in real time based on positioning modules such as the Global Navigation Satellite System (GNSS), and report its own moving speed to the server, so that the server can determine the communication reliable vehicle speed based on the moving speed of the detection device and business layer performance test results such as transmission delay, bit error rate, transmission packet loss rate, and information reception integrity. That is, when the moving speed of the detection device is lower than the communication reliable vehicle speed, the business layer performance test results such as transmission delay, bit error rate, transmission packet loss rate, and information reception integrity can be maintained within a specific range; the specific range can be set according to needs.
[0094] Based on this, the first information may also include a first speed corresponding to each detection point; the first speed represents the moving speed of the detection device at the corresponding detection point. After receiving the first information, the server may determine the communication reliable vehicle speed based on the first speed corresponding to each detection point and the detection result. Here, the specific calculation formula of the communication reliable vehicle speed may be set according to the requirements, and the embodiment of the present application does not limit this.
[0095] Accordingly, the embodiment of the present application also provides a data processing method, which is applied to a server, such as Figure 2 As shown, the method includes:
[0096] Step 201: receiving first information sent by a detection device;
[0097] Here, the first information includes the position of each detection point in the at least one detection point of the target area and the corresponding detection result; the detection result is a detection result related to signal quality obtained by the detection device performing quality detection on the signal sent by the at least one RSU arranged in the target area at the corresponding detection point based on reception of the signal sent by the at least one RSU;
[0098] Step 202: Based on the first information, evaluate the deployment status of the RSU.
[0099] In actual application, the evaluation of the deployment status of the RSU may include an overall evaluation of the deployment status of all RSUs in the target area, or may include a local evaluation of the deployment status of some RSUs in the target area, and the some RSUs may include at least one RSU.
[0100] In step 201, in actual application, the receiving of the first information sent by the detection device may include: receiving the first information periodically sent by the detection device, that is, periodically receiving the first information; in other words, the server receives the location of the detection point and the corresponding detection result in real time.
[0101] In step 202, in actual application, the detection result may include a signal strength, a transmission delay, a bit error rate, and a first distance corresponding to each RSU in at least one RSU.
[0102] Based on this, in one embodiment, evaluating the deployment status of the RSU based on the first information may include:
[0103] For each detection point, using the signal strength, transmission delay, bit error rate and first distance corresponding to each RSU in the at least one RSU included in the corresponding detection result, determine a first evaluation value corresponding to the corresponding RSU to obtain at least one first evaluation value; the first evaluation value represents the signal quality of the corresponding RSU;
[0104] Based on at least one first evaluation value corresponding to each detection point, the deployment status of the RSU is evaluated.
[0105] In actual application, the server may determine a specific formula for the first evaluation value using the signal strength, transmission delay, bit error rate and first distance corresponding to the corresponding RSU, which may be set according to requirements.
[0106] In actual application, the server may evaluate the deployment status of the RSU from multiple aspects.
[0107] Based on this, in one embodiment, the evaluating the deployment status of the RSU based on at least one first evaluation value corresponding to each detection point may include at least one of the following:
[0108] Based on at least one first evaluation value corresponding to each detection point, evaluating the signal coverage quality of the RSU;
[0109] Based on at least one first evaluation value corresponding to each detection point, evaluating the rationality of the installation position of the RSU;
[0110] Based on at least one first evaluation value corresponding to each detection point, a signal interference situation of the RSU is evaluated.
[0111] In one embodiment, the evaluating the signal coverage quality of the RSU based on at least one first evaluation value corresponding to each detection point may include:
[0112] Using at least one first evaluation value corresponding to each detection point, determine a second evaluation value corresponding to the corresponding detection point; the second evaluation value represents the signal quality of the corresponding detection point;
[0113] According to the second evaluation value corresponding to each detection point, the signal coverage quality corresponding to the corresponding detection point is determined by utilizing the corresponding relationship between at least one preset signal quality range and the signal coverage quality, so as to obtain the first evaluation result.
[0114] Here, the second evaluation value may be understood as the total quality of a signal sent by at least one RSU and received by the detection device at a corresponding detection point.
[0115] In actual application, the specific formula for the server to determine the second evaluation value using at least one first evaluation value corresponding to a corresponding detection point can be set according to requirements.
[0116] In actual application, when the detection device can receive signals sent by N RSUs at one detection point, due to the different distances between the detection point and each RSU, the signals sent by the M RSUs at a closer distance may be subject to the same-frequency interference of the signals sent by the NM RSUs at a farther distance. Therefore, when determining the second evaluation value corresponding to the corresponding detection point, the server needs to exclude the influence of the NM RSUs at a farther distance on the M RSUs at a closer distance. Wherein, N and M are integers greater than or equal to 0, and M is less than or equal to N; the first distance corresponding to each of the M RSUs is within the first range, and the first range can be set according to the RSU evaluation requirements in different scenarios. For example, when evaluating the deployment of RSUs for parking lots, urban roads and highways, the corresponding first ranges may be different due to the different maximum vehicle speeds in different scenarios. In addition, the signals sent by each of the NM RSUs can be understood as interference signals for the signals sent by the M RSUs, and the signal strength corresponding to the corresponding RSU can be determined as the strength of the interference signal.
[0117] In actual application, the correspondence between the signal quality range and the signal coverage quality can be set according to demand. Exemplarily, the correspondence between three signal quality ranges and signal coverage quality can be pre-set: when the second evaluation value is greater than or equal to 0, and less than or equal to 40, the server can determine the signal quality difference of the corresponding detection point, that is, the signal coverage quality difference corresponding to the corresponding detection point, and determine that the corresponding detection point is located in the signal coverage blind spot of at least one RSU set in the target area; when the second evaluation value is greater than or equal to 41, and less than or equal to 70, the server can determine that the signal quality of the corresponding detection point is good, that is, the signal coverage quality corresponding to the corresponding detection point is good, and determine that the corresponding detection point is located at the signal coverage boundary of at least one RSU set in the target area; when the second evaluation value is greater than or equal to 71, and less than or equal to 100, the server can determine that the signal quality of the corresponding detection point is excellent, that is, the signal coverage quality corresponding to the corresponding detection point is excellent, and determine that the signal coverage quality corresponding to the corresponding detection point is qualified.
[0118] In one embodiment, the method may further include:
[0119] The first assessment result is presented on a map of the target area.
[0120] In actual application, the form in which the server presents the first evaluation result on the map of the target area can be set according to needs, such as a heat map, adding an identifier that can reflect the first evaluation result to the map of the target area, etc.; the identifier can be in the form of text, picture, etc.
[0121] In actual application, the server may present the map of the target area through its own display screen, or may present the map of the target area on a web page.
[0122] In one embodiment, the evaluating the rationality of the installation position of the RSU based on at least one first evaluation value corresponding to each detection point may include:
[0123] Using at least one first evaluation value corresponding to each detection point, determine a second evaluation value corresponding to the corresponding detection point; the second evaluation value represents the signal quality of the corresponding detection point;
[0124] Compare the second evaluation value corresponding to each detection point with the first threshold to obtain a first comparison result;
[0125] According to the first comparison result corresponding to each detection point, it is determined whether the installation position of the at least one RSU is reasonable to obtain a second evaluation result.
[0126] In actual application, the first threshold can be set according to requirements.
[0127] In actual application, determining whether the installation position of the at least one RSU is reasonable according to the first comparison result corresponding to each detection point may include:
[0128] When the first comparison result indicates that the second evaluation value corresponding to the corresponding detection point is less than the first threshold, it is determined that the installation position of the at least one RSU is unreasonable, and an additional RSU needs to be added near the corresponding detection point, that is, a new RSU is added;
[0129] When the first comparison result indicates that the second evaluation value corresponding to the corresponding detection point is greater than or equal to the first threshold, it is determined that the installation position of the at least one RSU is reasonable.
[0130] Here, evaluating the rationality of the installation position of the RSU can be understood as evaluating the rationality of the layout of the RSU. In other words, based on at least one detection point in the target area, the rationality of the RSU layout of the local area in the target area (i.e., the area corresponding to a detection point) is evaluated to determine whether it is necessary to add RSU near each detection point.
[0131] In actual application, after the server determines that the installation location of the at least one RSU is unreasonable, that is, after determining that an additional RSU needs to be added near the corresponding detection point, it can give a location suggestion for adding the RSU according to a preset strategy.
[0132] Based on this, in one embodiment, the method may further include:
[0133] Determining, according to the second evaluation result, a position of at least one RSU that needs to be added;
[0134] The map of the target area presents the location of at least one RSU that needs to be added.
[0135] In actual application, the server may use a preset strategy to determine the position of at least one RSU that needs to be added. The specific strategy may be set according to demand, and the embodiment of the present application does not limit this.
[0136] In actual application, the server may evaluate the signal interference situation of the RSU according to a preset threshold.
[0137] Based on this, in one embodiment, evaluating the signal interference situation of the RSU based on at least one first evaluation value corresponding to each detection point may include:
[0138] For each detection point, each first evaluation value in the at least one first evaluation value is compared with the second threshold value to obtain at least one second comparison result; and the signal strength corresponding to each RSU included in the corresponding detection result is compared with the third threshold value to obtain at least one third comparison result;
[0139] According to at least one second comparison result and at least one third comparison result corresponding to each detection point, it is determined whether the signal sent by the at least one RSU is interfered, and a third evaluation result is obtained.
[0140] Here, it should be noted that evaluating the signal interference of the RSU specifically refers to interference evaluation for non-RSU signals. Exemplarily, when the detection device communicates with the RSU based on the PC5 interface, it can be determined whether the signal sent by the at least one RSU is interfered by the non-PC5 signal.
[0141] In actual application, the second threshold and the third threshold can be set according to requirements.
[0142] In practical application, determining whether a signal sent by the at least one RSU is interfered with according to at least one second comparison result and at least one third comparison result corresponding to each detection point may include:
[0143] For each first evaluation value of at least one first evaluation value corresponding to each detection point, when the second comparison result indicates that the corresponding first evaluation value is less than the second threshold, and the corresponding third comparison result indicates that the corresponding signal strength is greater than the third threshold, it is determined that the signal sent by the corresponding RSU is interfered by a non-RSU signal (i.e., other signals other than the signal sent by the RSU, such as a fifth generation mobile communication technology (5G) signal);
[0144] When the second comparison result indicates that the corresponding first evaluation value is greater than or equal to the second threshold, or when the corresponding third comparison result indicates that the corresponding signal strength is less than or equal to the third threshold, it is determined that the signal sent by the corresponding RSU is not interfered by the non-RSU signal.
[0145] Here, since the distances between the same RSU and each detection point are different, the server may have different signal interference evaluation results for the same RSU at different detection points. At this time, for each RSU set in the target area, the server may associate the signal interference evaluation results corresponding to the corresponding RSU at each detection point for subsequent processing, such as providing it to operation and maintenance personnel for manual analysis.
[0146] In actual application, the server may also provide data support for operation and maintenance personnel to maintain the RSUs set in the target area based on the first information.
[0147] Based on this, in one embodiment, the method may further include:
[0148] Based on the first information, operation and maintenance management is performed on the at least one RSU.
[0149] In one embodiment, the performing operation and maintenance management on the at least one RSU based on the first information may include:
[0150] Based on the first information, determining whether the at least one RSU is faulty and / or determining whether there is an illegally installed RSU in the at least one RSU, to obtain a fourth evaluation result;
[0151] Based on the fourth evaluation result, operation and maintenance management is performed on the at least one RSU.
[0152] Here, the illegally installed RSU may be understood as an RSU that is not permitted by the operator or is not registered in the operator's network.
[0153] In actual application, the server may determine whether the corresponding RSU is faulty based on the signal strength corresponding to each RSU and the first evaluation value.
[0154] Based on this, in one embodiment, determining whether the at least one RSU is faulty based on the first information may include:
[0155] For each detection point, it is determined whether the corresponding RSU is faulty based at least on the signal strength corresponding to each RSU in the at least one RSU and the first evaluation value.
[0156] In actual application, when the RSUs in the target area are deployed for the first time, the signals sent by each RSU can be measured at each detection point to determine the fault assessment benchmark of each RSU. Subsequently, the signal strength corresponding to the corresponding RSU can be compared with the signal strength in the corresponding fault assessment benchmark, and the first evaluation value corresponding to the corresponding RSU can be compared with the first evaluation value in the corresponding fault assessment benchmark, and whether the corresponding RSU is faulty can be determined based on the comparison result.
[0157] Specifically, when the difference between the signal strength corresponding to the corresponding RSU and the signal strength in the corresponding fault assessment benchmark is within the second range, and the difference between the first evaluation value corresponding to the corresponding RSU and the first evaluation value in the corresponding fault assessment benchmark is within the third range, it can be determined that the corresponding RSU is not faulty; when the difference between the signal strength corresponding to the corresponding RSU and the signal strength in the corresponding fault assessment benchmark does not fall within the second range, or when the difference between the first evaluation value corresponding to the corresponding RSU and the first evaluation value in the corresponding fault assessment benchmark does not fall within the third range, it can be determined that the corresponding RSU is faulty. Here, the second range and the third range can be set as required.
[0158] In actual application, the server can also determine the effective action distance corresponding to the corresponding RSU based on the bit error rate and the first distance corresponding to each RSU, and compare the effective action distance corresponding to the corresponding RSU with the effective action distance in the corresponding fault assessment benchmark, and determine whether the corresponding RSU is faulty according to the comparison result. Among them, the detection device may receive the signal sent by the same RSU at different detection points. Therefore, the server can use the bit error rate and the first distance corresponding to the same RSU identifier in different detection results to determine the effective action distance of the signal sent by the corresponding RSU. When the distance between the detection device and the corresponding RSU is less than or equal to the effective action distance, the bit error rate corresponding to the corresponding RSU determined by the detection device is within the fourth range, and the fourth range can be set according to demand.
[0159] Here, since the detection device may receive signals sent by the same RSU at different detection points, the server may have different fault assessment results for the same RSU at different detection points. At this time, for each RSU set in the target area, the server can finally determine that the corresponding RSU is not faulty only if it is determined at each detection point that the corresponding RSU is not faulty; as long as the corresponding RSU is determined to be faulty at any detection point, the server will finally determine that the corresponding RSU is faulty.
[0160] In one embodiment, determining, based on the first information, whether there is an illegally installed RSU in the at least one RSU may include:
[0161] For each detection point, determine the target signal strength using the signal strength corresponding to each RSU in the at least one RSU included in the corresponding detection result; compare the target signal strength with a fourth threshold to obtain a fourth comparison result; the target signal strength represents one of the following: the maximum signal strength corresponding to the corresponding detection point, the average signal strength corresponding to the corresponding detection point, and the total signal strength corresponding to the corresponding detection point;
[0162] According to the fourth comparison result corresponding to each detection point, it is determined whether there is an illegally installed RSU in the at least one RSU.
[0163] In actual application, the fourth threshold can be set according to requirements.
[0164] In actual application, determining whether there is an illegally installed RSU in the at least one RSU according to the fourth comparison result corresponding to each detection point may include:
[0165] When the fourth comparison result indicates that the target signal strength corresponding to the corresponding detection point is greater than the fourth threshold, it is determined that there is an illegally installed RSU in the at least one RSU, that is, there is an illegally installed RSU near the corresponding detection point;
[0166] When each fourth comparison result indicates that the target signal strength corresponding to the corresponding detection point is less than or equal to the fourth threshold, it is determined that there is no illegally installed RSU in the at least one RSU, that is, there is no illegally installed RSU in the target area.
[0167] In actual application, in order to improve the accuracy of detecting illegally installed RSUs, the target signal strength may be compared with a signal strength range. Specifically, the method may further include:
[0168] For each detection point, comparing the target signal strength with a fifth threshold to obtain a fifth comparison result; the fifth threshold is less than the fourth threshold;
[0169] Accordingly, determining whether there is an illegally installed RSU in the at least one RSU according to the fourth comparison result corresponding to each detection point may include:
[0170] According to the fourth comparison result corresponding to each detection point, combined with the corresponding fifth comparison result, it is determined whether there is an illegally installed RSU in the at least one RSU.
[0171] In actual application, the fifth threshold can be set according to requirements.
[0172] The determining, according to the fourth comparison result corresponding to each detection point and in combination with the corresponding fifth comparison result, whether there is an illegally installed RSU in the at least one RSU may include:
[0173] When the fourth comparison result indicates that the target signal strength corresponding to the corresponding detection point is greater than the fourth threshold, or when the corresponding fifth comparison result indicates that the target signal strength corresponding to the corresponding detection point is less than the fifth threshold, it is determined that there is an illegally installed RSU in the at least one RSU, that is, there is an illegally installed RSU near the corresponding detection point;
[0174] When each fourth comparison result represents that the target signal strength corresponding to the corresponding detection point is less than or equal to the fourth threshold, and each fifth comparison result represents that the target signal strength corresponding to the corresponding detection point is greater than or equal to the fifth threshold, it is determined that there is no illegally installed RSU in the at least one RSU, that is, there is no illegally installed RSU in the target area.
[0175] In one embodiment, performing operation and maintenance management on the at least one RSU according to the fourth evaluation result may include:
[0176] When the fourth evaluation result indicates that there is a faulty RSU and / or an illegally installed RSU in the at least one RSU, an alarm message is issued; the alarm message is used to instruct operation and maintenance management of the faulty RSU and / or the illegally installed RSU.
[0177] In actual application, the alarm information may include relevant information of the faulty RSU and / or the illegally installed RSU. After seeing the alarm information, the operation and maintenance personnel may repair the faulty RSU and / or remove the illegally installed RSU.
[0178] In actual application, the server may send the warning information to a target device, and the target device may be a mobile phone, other servers, etc., which is not limited in this embodiment of the present application.
[0179] In actual application, the server can also determine the broadcast channel congestion of the at least one RSU based on the first information. Specifically, since the broadcast channel of the at least one RSU is co-frequency, when the number of RSUs in the target area is too large, the service layer performance test results such as transmission delay, bit error rate, transmission packet loss rate, and information reception integrity in the detection results cannot be maintained within a specific range. At this time, the server can determine that the RSU in the target area has broadcast channel congestion.
[0180] The data processing method provided in the embodiment of the present application is that the detection device performs quality detection on the signal sent by at least one RSU set in the target area at each detection point of the at least one detection point in the target area, based on the reception of the signal sent by the at least one RSU, to obtain the detection result related to the signal quality; and sends the first information to the server; the first information includes the location of each detection point and the corresponding detection result; the server receives the first information; and based on the first information, evaluates the deployment of the RSU. In the scheme of the embodiment of the present application, the detection device performs quality detection on the signal sent by at least one RSU at each detection point in the target area, and sends the detection result related to the signal quality to the server to evaluate the deployment of at least one RSU; in this way, the server can use the detection result related to the signal quality to objectively and scientifically evaluate the deployment of the RSU, so as to improve the rationality of the RSU deployment based on the evaluation result.
[0181] The present application is further described in detail below in conjunction with application examples.
[0182] In this application embodiment, in order to evaluate and maintain the deployment status of the equipment operation status, installation location rationality, whether there is mutual interference, equipment online operation and maintenance, changes in equipment signal coverage, illegal installation, etc. after the RSU is deployed, an evaluation system including detection equipment and a cloud server is proposed; wherein the detection equipment can communicate with the RSU based on the PC5 interface. Specifically, the on-board detection equipment is used to receive the PC5 signal sent by the RSU, detect and obtain parameters such as location information and signal strength, and send it to the cloud server used as a calculation unit; the cloud server analyzes and calculates the location information, signal strength and other parameters sent by the detection equipment, evaluates the rationality of the RSU deployment, and combines heat maps, analysis result icons and other forms to display the signal coverage of the RSU in real time, so as to quantify the rationality of the RSU deployment, provide an objective evaluation mechanism, and provide data support and visualization guidance tools for the maintenance of the RSU.
[0183] The following is a detailed description of the workflow of the evaluation system in this application embodiment.
[0184] First, the on-board detection equipment receives the PC5 signal sent by the RSU and detects the relevant parameters of the signal quality.
[0185] Specifically, the detection equipment travels with the vehicle (i.e., moves in the target area), receives the PC5 signal emitted by the RSU set in the target area in real time, performs relevant tests on signal quality such as signal strength, and records relevant parameters.
[0186] In this application embodiment, the relevant parameters of signal quality may include relevant parameters of transmission layer performance and relevant parameters of business layer performance; the relevant parameters of transmission layer performance may include signal strength, interference signal strength (i.e., the signal strength corresponding to each RSU in the above-mentioned NM RSUs), effective working distance, reliable communication speed, decoding success rate, number of message packets received, number of receiving RSUs (i.e., the number of RSUs that the detection device can communicate with), broadcast channel congestion, etc.; the relevant parameters of business layer performance may include transmission bit error rate, transmission packet loss rate, transmission delay, information reception integrity, etc.
[0187] Among them, the parameters that the detection equipment can directly determine include signal strength, transmission delay, transmission bit error rate, distance from the RSU (i.e. the first distance mentioned above), decoding success rate, number of message packets received, transmission packet loss rate, information reception completeness and vehicle speed; other related parameters are calculated by the cloud server based on the information reported by the detection equipment (i.e. the first information mentioned above).
[0188] Secondly, the detection device associates the high-precision location information (such as longitude and latitude coordinates) it has acquired with the relevant parameters of the PC5 signal of the RSU detected at the corresponding position, and uploads the association result (i.e. the first information mentioned above) to the cloud server for relevant calculations of the signal quality.
[0189] Specifically, assuming that the detection device can detect the PC5 signals of n RSUs at one detection point, the quality perception strength (i.e., the above-mentioned first evaluation value) of the PC5 signal of the i-th (i is greater than 0 and less than or equal to n) RSU by the detection device can be calculated by the following formula:
[0190]
[0191] Among them, W i represents the signal quality perception strength of the i-th RSU; S represents the PC5 signal strength of the RSU; P represents the bit error rate; T represents the delay; L represents the distance between the detection point and the RSU (i.e., the first distance mentioned above); k1 and k2 are weighting coefficients, which are fixed constants set according to the influence of weather, temperature and other factors on signal quality (which can be set based on experience); the role of k1 and k2 is to perform regularization normalization on the two types of evaluation data so that they are under the same influencing factor.
[0192] Based on formula (1), the quality evaluation value of the PC5 signal of the final RSU of the detection device at the detection point (i.e., the second evaluation value mentioned above) can be calculated by the following formula:
[0193]
[0194] Among them, FW represents the final signal quality evaluation value of a detection point; m represents the number of RSUs within the maximum distance threshold range (i.e. the above-mentioned first range) (i.e. the above-mentioned M RSUs that are closer to the detection point), and the maximum distance threshold range can be understood as the maximum distance of the RSU concerned by the detection point, and different thresholds can be determined according to the maximum vehicle speed in different scenarios, such as parking lots, urban roads, highways, etc.; n represents the number of all RSUs that can receive PC5 signals at the detection point (i.e. the above-mentioned N RSUs); K represents the weighted coefficient of the impact of the PC5 signals of the non-concerned nm RSUs (i.e. the above-mentioned NM RSUs that are farther away from the detection point) on the PC5 signals of the concerned m RSUs on the same frequency. In other words, the signals sent by the RSUs beyond the maximum distance threshold range can be understood as noise, that is, K represents the overall weighted coefficient of the PC5 signals of the RSUs determined to be noise; i represents the index of the concerned m RSUs; k i represents the weight coefficient of the ith RSU among the m RSUs of interest; j represents the index of the nm RSUs of no interest; k j represents the weighting coefficient of the jth RSU among the nm RSUs of no concern; K, k i , k j The k corresponding to the RSU with different distances from the detection point can be set according to the requirements. i or k j Can be different.
[0195] In practical applications, FW is usually greater than or equal to 0 and less than or equal to 100.
[0196] Exemplarily, as shown in Table 1, the cloud server can output the detection points and the corresponding detection results and quality assessment results in real time.
[0197]
[0198] Table 1
[0199] Third, the cloud server evaluates the deployment of RSUs.
[0200] On the one hand, the cloud server can evaluate the signal quality and signal coverage of the detection point according to the calculation results of formula (2):
[0201] When FW is in the range of 0 to 40, the signal quality of the corresponding detection point is poor, which can be determined as a coverage blind area;
[0202] When FW is in the range of 41 to 70, the signal quality of the corresponding detection point is good and can be determined as coverage critical (i.e., coverage boundary);
[0203] When FW is in the range of 71 to 100, the signal quality of the corresponding detection point is excellent and can be determined as qualified coverage.
[0204] On the other hand, Figure 3 As shown, the cloud server can fuse the signal quality with the map of the target area, combine the location information of the detection point and the PC5 signal quality evaluation value (i.e., FW) of the RSU with the plane map of the target area, and obtain a heat map that can reflect the PC5 signal coverage of the RSU.
[0205] Fourth, the cloud server evaluates the rationality of the deployment of RSU.
[0206] In this application embodiment, after initial deployment of RSUs in the selected area (i.e., the target area), the cloud server can evaluate the rationality of the deployment of RSUs from the following two aspects:
[0207] 1) Installation location evaluation; Specifically, the cloud server performs signal quality detection and rationality evaluation of the installation location for the initial deployment according to a preset threshold. If the signal quality evaluation value (i.e., FW) of the detection point is lower than the preset signal quality threshold (i.e., the first threshold mentioned above), it is determined that the RSU layout near the corresponding detection point is unreasonable, that is, the RSU that the detection device can communicate with at the detection point can be determined as an unreasonable device; and the cloud server can Figure 3 The heat map shown is visualized in the form of highlighting, and recommended locations for adding RSUs are given.
[0208] 2) Interference detection; specifically, the cloud server evaluates the signal strength and signal quality of the initial deployment according to the preset threshold. If the signal quality perception intensity W of the RSU is lower than the preset signal quality threshold (i.e., the second threshold mentioned above), and the signal strength of the RSU is higher than the preset signal strength threshold (i.e., the third threshold mentioned above), the cloud server will automatically output the interference detection evaluation result of the RSU: the RSU has multipath interference or mutual interference; the interference here refers to the interference of other signals except the PC5 signals of the nm RSUs of concern, such as 5G signals.
[0209] Fifth, the cloud server performs operation and maintenance monitoring.
[0210] In this application embodiment, the RSU signal quality evaluation value after deployment and delivery can be stored in the cloud server as an evaluation benchmark in the subsequent operation and maintenance process. In addition, the cloud server can perform RSU operation and maintenance management from the following two aspects:
[0211] 1) Signal changes; Specifically, the cloud server can regularly inspect the signal quality of the RSU during the operation and maintenance process, and compare it with the evaluation benchmark at the time of deployment and delivery in real time. If the difference between the relevant parameters of an RSU (such as signal strength, signal quality, etc.) is lower than the evaluation benchmark (that is, the difference between the relevant parameters and the evaluation benchmark) exceeds the system preset range (such as the second range, the third range and the fourth range mentioned above), the cloud server will automatically issue an alarm message, which indicates that the RSU device has a fault, and send the alarm message to the target device.
[0212] 2) Illegally installed RSU equipment; specifically, during the operation and maintenance process, if the maximum signal strength of a detection point is detected in real time to be higher than the preset threshold (i.e., the fourth threshold mentioned above), the cloud server will automatically determine that there is a signal of an illegally installed RSU device near the detection point and send an alarm message to the target device.
[0213] The solution provided by this application embodiment has the following advantages:
[0214] 1) Based on the quality detection results of the PC5 signal sent by the on-board detection equipment to the RSU, the RSU signal quality perception strength (W) and the PC5 signal quality evaluation value (FW) are calculated through the calculation unit, so as to evaluate the rationality of the RSU deployment, and combined with the road map of the target area road, the signal coverage of the RSU is displayed in real time, providing objective data support for the maintenance of the RSU, that is, providing a digital and visual maintenance guidance tool; in this way, the deployment of the RSU can be displayed in real time in a more objective, real, convenient and intuitive way, ensuring the rationality of the RSU deployment and the scientificity and convenience of the RSU maintenance.
[0215] 2) It is able to obtain the vehicle position through the detection equipment in real time, realize a more realistic and scientific perception of the information coverage of the accompanying place (i.e., the detection point), and combine the positioning information obtained by the RSU itself (i.e., using the positioning information of the detection equipment and the positioning information of the RSU to determine the distance between the detection point and the RSU), it is able to more accurately evaluate the coverage and operating status of the RSU.
