Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The following describes in detail a car washing method, a storage medium and an automatic train monitoring system for a train according to an embodiment of the present invention with reference to fig. 1 to 5 of the specification and a specific embodiment.
Fig. 1 is a flow chart of a method of washing a train in accordance with one embodiment of the invention. As shown in fig. 1, the car washing method of the train comprises the following steps:
s1, acquiring an ex-warehouse image and an in-warehouse image of a train.
Specifically, the ATS system can be used for acquiring a delivery image when the train is delivered to the warehouse so as to know the surface pollution condition of the train body when the train is delivered to the warehouse. And acquiring a warehouse-in image of the train when the train is warehouse-in so as to know the surface dirty condition of the train body when the train is warehouse-in.
In the embodiment of the invention, the train scanning device can be arranged around the appointed route of the train entering and exiting warehouse. And (3) performing whole-body scanning on the train passing by the train scanning device during ex-warehouse and warehouse-in so as to acquire ex-warehouse images and warehouse-in images of the train.
In the embodiment of the invention, the train scanning device collects the whole body images of the train when the train goes out of the warehouse and goes in the warehouse according to the proportion of 1:1, namely, the train goes out of the warehouse and goes in the warehouse according to the same collection part, area and proportion.
In an embodiment of the invention, the train scanning device may comprise a line scanning camera for capturing images.
S2, judging whether car washing is needed or not according to the ex-warehouse image and the warehouse-in image.
Specifically, according to the ex-warehouse image and the warehouse-in image, the surface dirty comparison condition of the train before and after ex-warehouse and warehouse-in can be known, whether the train needs to be washed or not is judged according to the actual surface condition of the train body, the accuracy of judging the train needs to be washed can be improved, when the need of washing is confirmed, the train can be controlled in time and washed, and the timeliness and the efficiency of train washing are improved.
In an embodiment of the present invention, as shown in fig. 2, determining whether car washing is required according to the ex-warehouse image and the warehouse-in image may include:
s21, matching the ex-warehouse image and the warehouse-in image by using a normalized cross correlation NCC (Normalized Cross Correlation ) algorithm to obtain matching information.
In the embodiment of the present invention, as shown in fig. 3, matching processing is performed on the outbound image and the inbound image by using a normalized cross correlation NCC algorithm, so as to obtain matching information, which may include:
s211, calculating a first integral graph of the warehouse-in image and a second integral graph of the warehouse-in image;
s212, carrying out normalized cross correlation NCC calculation by using the first integral diagram and the second integral diagram according to the preset window size;
s213, obtaining matching information according to the NCC calculation result and a preset matching threshold, wherein the matching information comprises a matching area or a non-matching area.
Specifically, the NCC algorithm is a matching method based on image gradation information. When the matching area or the unmatched area of the ex-warehouse image and the warehouse-in image is acquired, an integral graph (a first integral graph) of the ex-warehouse image and an integral graph (a second integral graph) of the warehouse-in image can be calculated first. After the first integral map and the second integral map are obtained, a window size (preset window size) is set. And carrying out normalized cross correlation NCC calculation by using the first integral graph and the second integral graph according to a preset window area (preset window size) to obtain an NCC calculation result of the preset window area. The NCC algorithm limits the NCC calculation result to the range of [ -1,1], if the NCC calculation result = -1, it indicates that the two matching windows are completely uncorrelated, whereas if the NCC calculation result = 1, it indicates that the two matching windows are very correlated. It can be seen that the correlation degree of the preset window area corresponding to the ex-warehouse image and the warehouse-in image can be known according to the NCC calculation result.
In the embodiment of the invention, the preset matching threshold value which actually meets the requirement of car washing is 0.2 through the calculation, comparison and verification of the data before and after the train goes out and goes in the warehouse for many times. When the NCC calculation result is smaller than 0.2, the preset window area is indicated to be a matching area. When the NCC calculation result is larger than 0.2, the preset window area is a mismatch area.
The outgoing image and the outgoing image are equal-scale images. In order to achieve a better effect, the acquired equal-proportion ex-warehouse images and the acquired equal-proportion ex-warehouse images are respectively arranged in sequence and then spliced into complete and clear train images. To facilitate NCC calculations.
S22, judging whether car washing is needed according to the matching information.
In an embodiment of the present invention, as shown in fig. 4, determining whether car washing is required according to the matching information may include:
s221, determining the number of stain areas according to the matching areas or the unmatched areas in the matching information;
s222, determining that car washing is needed when the number of the stain areas is larger than a preset stain threshold value.
Specifically, the number of the matching areas or the number of the unmatched areas is counted to determine the number of the stain areas. The number of the unmatched areas is the number of the stain areas. When the number of the stain areas is calculated according to the number of the matching areas, the number of the matching areas can be obtained by subtracting the number of the matching areas according to the total number of the preset window areas. When the number of the stain areas is smaller than a preset stain threshold value, the temporary no-need car washing of the train can be recorded. When the number of the stain areas is larger than a preset stain threshold value, the need of train washing can be recorded.
In an embodiment of the present invention, the car washing method of the train may further include: acquiring air quality information and/or rainfall information in the process of train delivery operation; and if the air quality information or the rainfall information meets the preset car washing conditions, determining that car washing is needed.
In embodiments of the invention, a PM2.5 sensor may be used to collect air quality information. A rain sensor may be used to collect the rain information. For better effect, a plurality of PM2.5 sensors can be arranged in a train body and a train, and the average value of a plurality of air quality information is used as the air quality information value in the process of train delivery operation. The rain sensor may be located at the front windshield of the train.
In this embodiment, the air quality information satisfies a preset car washing condition, which may include: the cumulative duration of the contaminant concentration in or out of the train in the first zone exceeds a first preset duration and/or the cumulative duration of the contaminant concentration in or out of the train in the second zone exceeds a second preset duration, wherein the value in the second zone is greater than the value in the first zone, the second preset duration is less than the first preset duration, and/or the cumulative duration of the contaminant concentration in or out of the train in a third zone exceeds a third preset duration, wherein the value in the third zone is greater than the value in the second zone, and the third preset duration is less than the second preset duration.
In the embodiment of the invention, the preset car washing conditions can be configured according to the actual detection values of different areas, and the following references are made: according to the new air quality standard of the PM2.5 detection network, the 24 hour average standard value can set the threshold value as follows in Table 1:
table 1 air quality rating table
| Air quality grade | 24 hour PM2.5 average standard value |
| Excellent (excellent) | 0～35μg/m 3 |
| Good grade (good) | 35～75μg/m 3 |
| Light pollution | 75～115μg/m 3 |
| Moderate contamination | 115～150μg/m 3 |
| Severe contamination | 150～250μg/m 3 |
| Severe pollution | Greater than 250 mug/m 3 The above |
As an example, the first interval of contaminant concentration is 115-150 μg/m 3 (moderate contamination) for a first preset period of 24 hours. The second interval of contaminant concentration is 150-250 μg/m3 (heavy contamination) for a second preset period of 12 hours. The third interval of the pollutant concentration is more than 250 mug/m 3 And above (severe contamination), a third preset time period of 6 hours. Wherein, mu g/m 3 Indicating the mass of particles contained in each cubic meter of air. Specifically, when the concentration of the contaminant in the train or outside the train is in the first zone 115-150. Mu.g/m 3 The accumulated time of (2) exceeds 24 hours, and the concentration of the pollutants in or outside the train is in the second interval150-250μg/m 3 The integrated duration of (2) exceeds 12 hours, and the concentration of the pollutants in or outside the train is greater than 250 mu g/m in a third interval 3 And when the accumulated time exceeds at least one of 6 hours, the current external air quality pollution is considered to be serious, a car washing plan is required to be started for the train returned to the warehouse, and the need of car washing of the train is recorded.
In this embodiment, the rainfall information satisfies a preset car washing condition, which may include: the accumulated time when the rainfall is greater than the preset rainfall threshold is greater than the fourth preset duration.
Specifically, after the train is delivered out of the warehouse, the information acquisition module uses the rainfall sensor to acquire whether the outside of the train is rainy or not and the data of the rainfall during running of the train, and transmits the data to the ATS server. If the rainfall is greater than the preset rainfall threshold and the accumulated time is greater than the fourth preset duration, recording that the train needs to be washed after running.
In the embodiment of the invention, the preset rainfall threshold and the fourth preset duration can be configured according to the actual requirements of different lines, and the preset rainfall threshold is 10mm/min and the fourth preset duration is 1 hour.
In an embodiment of the present invention, the car washing method of the train may further include: acquiring the interval time from the last car washing; if the interval time is greater than or equal to the preset duration threshold, determining that car washing is required.
Specifically, whether the car is required to be washed or not is determined, the recorded time of last washing of the train can be obtained, and the interval time of last car washing of the current distance is calculated. If the interval time from the last car washing is smaller than the preset duration threshold value, the car washing is not needed. And if the interval time is greater than or equal to the preset duration threshold, determining that the vehicle needs to be washed.
For better effects, when no record of car washing is queried, if car washing is not needed according to the ex-warehouse image and the warehouse-in image, and the air quality information or the rainfall information does not meet the preset car washing condition, and when car washing is not needed, the interval time from the last car washing can be acquired again to judge whether car washing is needed or not, so that the timeliness of train washing is improved.
S3, determining that carwash is required, setting a carwash plan for the train, and carrying out carwash control according to the carwash plan.
Specifically, after determining that a car is required to be washed, the ATS server automatically sets a car washing plan for the train after the train enters (i.e., passes through a train scanning device on one side of the warehouse entry), and washes the train according to the set car washing plan.
As a possible embodiment, as shown in fig. 5, setting a car washing plan for a train and performing car washing control according to the car washing plan may include:
s31, setting a car washing destination head code for the train, opening a path to a car washing garage, and controlling the train to enter the car washing garage;
s32, determining the stopping and stabilizing of the train, controlling a car washer of a car washing garage to wash the car, and controlling the train to keep braking;
s33, determining that the car is washed, setting a return warehouse header code for the train, opening a return warehouse access, and controlling the train to return warehouse.
Specifically, a destination head code of the cleaning train is automatically set, a route of the cleaning garage is automatically triggered, a route of the cleaning garage is opened, and after a CI (Computer Interlocking, computer interlocking and a subsystem of the train automatic control system take computer technology as a core and a general term of control and protection technologies such as a route, a turnout, a annunciator and the like are automatically realized), a signal is developed, the train automatically enters the cleaning garage. After the train enters the garage and stops steadily, if the car washer is already started and enters a standby state, the ATS (Automatic Train Supervision, automatic train monitoring system) issues a car washer and the train at the same time to start a car washing command. After the train receives a command for starting to wash the train, the brake is kept unreleasable. The car washer starts to wash the car until the washing is finished. After the train is cleaned, a return warehouse header code is set for the train, a return warehouse approach is opened, and the train is controlled to return to the warehouse. And after the train is cleaned, returning the train to the warehouse, and completing the cleaning of the train.
In the embodiment of the invention, if the train does not have a car washing requirement, after the train passes through the train scanning device, the ATS server automatically sets a head code (a purposeful non-planned train capable of realizing automatic triggering of the route) reaching the destination in the warehouse for the train, and automatically triggers the head code reaching the destination. After the CI develops the signal, the train automatically enters the parking garage.
According to the train washing method, whether the train needs to be washed or not is determined according to the actual condition of the surface of the train body by acquiring the ex-warehouse image and the in-warehouse image of the train, and the accuracy of judging whether the train needs to be washed or not is improved. After the train is determined to be required to be cleaned, a train cleaning plan is set for the train, and the cleaning of the train is controlled to be completed, so that the automatic degree of train cleaning is improved, and the labor cost is reduced.
