Description of the Drawings
[0042] Figure 1 Structural diagram of a monitoring system for collecting and assessing operation data of a sanitation vehicle according to the present invention. Specific implementation manners
[0043] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following implementation manners are merely examples, and a monitoring system for collecting and assessing operation data of a sanitation vehicle involved in the present invention is not limited to the structures described in the following implementation manners. All other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.
[0044] As Figure 1 shown, the present invention provides a monitoring system for collecting and assessing operation data of a sanitation vehicle, including a primary data collection module, a data acquisition module, an operation data analysis module, an operation data assessment module, and a real-time monitoring module;
[0045] The primary data collection module preliminarily collects data of the sanitation vehicle using a multi-source sensor group, and performs preprocessing operations such as cleaning and noise reduction, filtering, and timestamp alignment on the data preliminarily collected by the multi-source sensor group; the multi-source sensor group includes, but is not limited to, GPS / Beidou positioning, an inertial measurement unit, an on-vehicle camera, a dustbin weight sensor, a hydraulic pressure sensor, a fuel consumption flowmeter, and a dust sensor, etc.; the GPS / Beidou positioning can select any one of GPS or Beidou positioning, and the hydraulic pressure sensor is used to detect the cleaning device.
[0046] The data acquisition module is used to verify the data preliminarily collected by the primary data collection module and calculate the data credibility to obtain more reliable data; the data preliminarily collected by the primary data collection module includes, but is not limited to, the position, fuel consumption, and operation duration of the sanitation vehicle, etc.
[0047] The operation data analysis module is used to analyze the operation data, obtain the actual operation actions of the sanitation vehicle, and calculate the effectiveness of the operation trajectory and the fuel consumption efficiency of the sanitation vehicle.
[0048] The operation data assessment module constructs an assessment system by using the analytic hierarchy process to obtain the assessment score of the sanitation vehicle.
[0049] The real-time monitoring module is used to perform real-time operation monitoring on the sanitation vehicle and receive warning prompts for warning display.
[0050] In this embodiment, it should be specifically noted that the data acquisition module verifies the data preliminarily collected by the primary data collection module based on a sliding window, sets a dynamic threshold for the sliding window, and performs verification if the threshold is exceeded.
[0051] YU dynamic = μ window ±3σ window ;
[0052] Among them, YU dynamic represents the dynamic threshold of the sliding window, μ window represents the arithmetic mean of the data within the current time window, reflecting the central tendency of the data; σ window represents the standard deviation of the data within the current time window, characterizing the degree of data dispersion; in this embodiment, the time window is set to 10 seconds, and those skilled in the art can modify it according to the actual situation, and this embodiment does not make specific limitations on this;
[0053] When the data exceeds the dynamic threshold, it is marked as an outlier and the verification process is triggered; the specific verification process is as follows: the outlier data is transmitted to the background terminal for expert determination. If it is a normal fluctuation value, the data is modified to the normal value, and the value modified by the background terminal cannot be verified again. If it is an abnormal data value, it is eliminated; in the actual data acquisition process, the sensor will be affected by the environment. Therefore, expert determination is required, and combined with the actual environmental situation and experience, the outlier is rechecked to improve the accuracy of the data, laying a foundation for subsequent data analysis;
[0054] During the data transmission and storage process, an incremental data marking mechanism based on the MQTT protocol can be adopted to automatically record the position of the last valid data packet when the network is interrupted, and optimize the retransmission of missing data after reconnecting; use a RAID 6 array to store key job data, allowing two hard disks to be damaged simultaneously and still be able to recover the complete data; and the blockchain technology can be combined to store key data to achieve tamper-proof evidence storage.
[0055] In this embodiment, it should be specifically noted that the formula for the data acquisition module to calculate the data credibility is expressed as:
[0056] KX a = w a ×H a ; among them, KX a represents the credibility of the data of the a-th sensor, w a represents the credibility weight of the data of the a-th sensor, H a represents the data health of the a-th sensor;
[0057]
[0058] Among them, N valid_a represents the number of valid data of the a-th sensor within a unit time, N total represents the total amount of data of the a-th sensor within a unit time, σ offset_aDenote the standard deviation of the clock offset of the a-th sensor as μ offset_a Denote the mean of the clock offset of the a-th sensor; k1 and k2 are the corresponding empirical calibration coefficients respectively, which can be specifically set by those skilled in the art according to the actual situation. In this embodiment, k1 = 0.7 and k2 = 0.3 are taken;
[0059]
[0060] Among them, λ represents the time decay coefficient, usually taking λ = 0.01. In case of rain or snow weather, it can be adjusted to λ = 0.015; t a Denote the service life of the a-th sensor, F error_a Denote the number of historical data errors of the a-th sensor, F total_a Denote the total amount of historical data of the a-th sensor;
[0061] When the data credibility KX a Satisfies KX a ≥ IU2, then increase the data weight of the a-th sensor, and assign more weights in subsequent analysis to improve the accuracy and effectiveness of data analysis;
[0062] When the data credibility KX a Satisfies IU1 ≤ KX a < IU2, then keep the data weight of the a-th sensor unchanged; maintain the original set weight unchanged in subsequent analysis;
[0063] When the data credibility KX a Satisfies KX a < IU1, then reduce the data weight of the a-th sensor, and assign less weights in subsequent analysis to prevent inaccurate analysis results caused by too low data accuracy.
[0064] In this embodiment, it should be specifically noted that the actual operation action of the sanitation vehicle, that is, whether the vehicle is operating, sets the constraint conditions during the operation of the sanitation vehicle. The constraint conditions are the switch states of each working component during the operation of the sanitation vehicle, such as the sweeping turntable, water spraying valve, etc. When the working component is opened, it is assigned a value of 1, and when the working component is closed, it is assigned a value of 0; if during the operation of the sanitation vehicle, the operation data does not meet the constraint conditions, then mark the actual operation action of the sanitation vehicle as not operating; if during the operation of the sanitation vehicle, all the operation data meet the constraint conditions, then mark the actual operation action of the sanitation vehicle as operating; when the marked actual operation action of the sanitation vehicle is inconsistent with the preset operation action, send a warning prompt to the real-time monitoring module; the preset operation action is the theoretical operation action of the sanitation vehicle. If the sanitation vehicle is dispatched to perform an operation task, the preset operation action of this sanitation vehicle is operating, and if the sanitation vehicle is not dispatched to perform an operation task, the preset operation action of this sanitation vehicle is not operating.
[0065] In this embodiment, it should be specifically noted that the specific method for the operation data analysis module to calculate the effectiveness of the operation trajectory of the sanitation vehicle is as follows:
[0066] Through the GIS geofencing technology, the operation task area of the sanitation vehicle is divided into n sub-areas, which are classified into a core area and a general area. Operation weights are set for the core area and the general area respectively. The operation weight of the core area is set to 1.2, and the operation weight of the general area is set to 1;
[0067]
[0068] Among them, PP represents the effectiveness of the operation trajectory of the sanitation vehicle, S gh_i represents the preset cleaning area of the i-th area, which can be set as the area of the i-th area or the cleaning area set in advance; S acu_i (t) represents the actual cleaning area of the vehicle in the i-th area at time t, which can be jointly calculated by hydraulic pressure and vehicle speed; Δt represents the operation time window, that is, the selected time interval. If the next moment is t′, then Δt = t′ - t, and the value of Δt can be set or modified by those skilled in the art according to the actual situation. In this embodiment, Δt = 30s is selected; δ i (t) represents the effectiveness coefficient of the i-th area at time t, which is assigned according to the garbage residue situation after cleaning. If garbage residue is detected, then δ i (t) = 0, and the cleaning area during this period is regarded as invalid. If no garbage residue is detected, then δ i (t) = 1; the garbage residue situation can collect images by setting up a camera, identify the garbage residue through the YOLOv5 model, and output a binary result; i = 1, 2, 3,..., n;
[0069] S acu_i (t) = v i (t) × L deuq × P i (t);
[0070] Among them, v i (t) represents the vehicle speed in the i-th area at time t, which can be obtained by the inertial measurement unit; L deuq represents the effective width of the cleaning device, which is a fixed parameter and is set according to the specific situation of the cleaning device of the sanitation vehicle; P i (t) represents the hydraulic pressure normalization coefficient of the i-th area at time t, and the value range is (0, 1).
[0071] In this embodiment, it should be specifically noted that the calculation formula of the fuel consumption efficiency is expressed as:
[0072]
[0073] Among them, η represents the fuel consumption efficiency of the sanitation vehicle, and H total represents the total fuel consumption of the sanitation vehicle, D i represents the operating mileage of the i-th area, L i represents the garbage loading volume of the i-th area, and ρ1 and ρ2 are the corresponding proportionality factors, taking ρ1 = 0.6 and ρ2 = 0.4;
[0074] The fuel consumption efficiency and the effectiveness of the operation trajectory are both calculated after the sanitation vehicle completes each operation task, and are used to evaluate the operation of the sanitation vehicle.
[0075] In this embodiment, it should be specifically noted that the analytic hierarchy process adopted by the operation data assessment module includes an objective layer, a criterion layer, and an index layer; the objective layer is the assessment score, which reflects the overall score of the operation of the sanitation vehicle and is used for horizontal comparison; the criterion layer includes operation quality, resource consumption, and compliance, and the compliance is the implementation situation of the operation specifications and safety procedures of the sanitation vehicle; the index layer includes the effectiveness of the operation trajectory, operation punctuality, fuel consumption efficiency, equipment loss rate, and the number of violations of the sanitation vehicle, and the operation punctuality is whether the time to complete the operation task is within the specified time; the indicators of the operation quality are the effectiveness of the operation trajectory and operation punctuality, the indicators of the resource consumption are the fuel consumption efficiency and equipment loss rate, and the indicator of the compliance is the number of violations of the sanitation vehicle;
[0076] Persons in this field can add or modify the content of the criterion layer and the index layer according to specific situations;
[0077] Based on the criterion layer, a comparison matrix C is constructed, and experts conduct 1-9 scale scoring on the importance of operation quality, resource consumption, and compliance in the criterion layer. For example, if the operation quality B1 is 3 times more important than the resource consumption B2, then c12 = 3;
[0078] By calculating the eigenvector corresponding to the maximum eigenvalue of matrix C, the weight is obtained after normalization, and the consistency test of the calculation matrix is carried out. If the consistency ratio is less than 0.1, the matrix is determined to be effective;
[0079] Based on the index layer, a comparison matrix D is constructed, and experts conduct 1-9 scale scoring on the importance of each index in the index layer; the weight is set based on the data credibility of each sensor data, and the consistency test of the calculation matrix D is carried out. If the consistency ratio is less than 0.1, the matrix is determined to be effective;
[0080] The assessment score is obtained by layer-by-layer weighting of the criterion layer and the index layer, and the value of the objective layer is used as the assessment score of the sanitation vehicle.
[0081] Finally, the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
[0082] As described above, this is only the specific implementation manner of this application. However, the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed in this application can easily think of changes or replacements, which should all be covered within the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claims.
