Description

Technical Field

[0001] The present invention belongs to the technical field of rail transit monitoring, and particularly relates to a method and device for monitoring and analyzing the passenger flow situation on a vehicle. Background Art

[0002] Under the current subway operation conditions, subway passengers often choose the waiting areas near elevators and entrances to wait for the train. Such concentrated travel and crowded boarding lead to uneven distribution of passengers in the carriages, resulting in the phenomenon that some carriages are empty while some are crowded. The monitoring and management center needs to give guiding prompts to the passengers in the crowded carriages, and the data source for such guiding prompts is the camera units installed in the carriages.

[0003] When using camera units to monitor the passenger flow in the carriage, there is a contradiction between the input cost and the monitoring accuracy. That is, if the number of installed camera units is small, when the passenger flow is crowded, the video image data collected by the camera units may be blocked due to the crowding, resulting in errors in subsequent video image recognition and unable to accurately reflect the monitoring data of the passenger flow in the carriage. If the number of installed camera units is large, although the monitoring accuracy of the passenger flow in the carriage is high, the cost increase caused by the camera units is also a thorny problem. If low-quality camera units are selected to reduce the cost, it will also cause problems with the monitoring accuracy of the passenger flow in the carriage. Therefore, how to improve the real-time monitoring accuracy of the passenger flow in the carriage when the cost of the camera units is fixed is a defect that needs to be solved urgently.

[0004] Therefore, at the present stage, it is necessary to design a method and device for monitoring and analyzing the passenger flow situation on a vehicle to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a method and device for monitoring and analyzing the passenger flow situation on a vehicle to solve the technical problems existing in the above-mentioned prior art. When using camera units to monitor the passenger flow in the carriage, there is a contradiction between the input cost and the monitoring accuracy. That is, if the number of installed camera units is small, when the passenger flow is crowded, the video image data collected by the camera units may be blocked due to the crowding, resulting in errors in subsequent video image recognition and unable to accurately reflect the monitoring data of the passenger flow in the carriage. If the number of installed camera units is large, although the monitoring accuracy of the passenger flow in the carriage is high, the cost increase caused by the camera units is also a thorny problem. If low-quality camera units are selected to reduce the cost, it will also cause problems with the monitoring accuracy of the passenger flow in the carriage.

[0006] To achieve the above purpose, the technical solution of the present invention is:

[0007] A vehicle passenger flow monitoring device, comprising a camera acquisition device, an infrared scanning device, a local positioning device, a camera moving device, an infrared moving device, an abnormality judging device, a standby camera acquisition device, a standby infrared scanning device, and an emergency dispatching device;

[0008] The camera acquisition device is used to acquire the passenger flow data of the target carriage, denoted as the first passenger flow data;

[0009] The infrared scanning device is used to acquire the passenger flow data of the target carriage, denoted as the second passenger flow data;

[0010] The local positioning device is used to perform local positioning on the area where the first passenger flow data does not match the second passenger flow data;

[0011] The camera moving device is used to move the camera acquisition device according to local positioning;

[0012] The infrared moving device is used to move the infrared scanning device according to local positioning;

[0013] The abnormality judging device is used to judge whether the camera acquisition device and the infrared scanning device are abnormal;

[0014] The standby camera acquisition device is used to act when the camera acquisition device is abnormal;

[0015] The standby infrared scanning device is used to act when the infrared scanning device is abnormal;

[0016] The emergency dispatching device is used to dispatch the standby camera acquisition device to the location of the camera acquisition device, and dispatch the standby infrared scanning device to the location of the infrared scanning device.

[0017] Further, the camera acquisition device and the infrared scanning device are always on; the local positioning device, the camera moving device, the infrared moving device, the abnormality judging device, the standby camera acquisition device, the standby infrared scanning device, and the emergency dispatching device are always off;

[0018] When the first passenger flow data does not match the second passenger flow data, the local positioning device, the camera moving device, and the infrared moving device are turned on;

[0019] When the camera moving device moves the camera acquisition device to the location of local positioning, the acquired passenger flow data is denoted as the first passenger flow inspection data; when the infrared moving device moves the infrared scanning device to the location of local positioning, the acquired passenger flow data is denoted as the second passenger flow inspection data; if the first passenger flow inspection data does not match the second passenger flow inspection data; then the abnormality judging device is turned on;

[0020] If the first passenger flow inspection data matches the first passenger flow data, and the second passenger flow inspection data does not match the second passenger flow data, the anomaly determination device determines that the infrared scanning device is abnormal; if the first passenger flow inspection data does not match the first passenger flow data, and the second passenger flow inspection data matches the second passenger flow data, the anomaly determination device determines that the camera acquisition device is abnormal;

[0021] If it is determined that the infrared scanning device is abnormal, the standby infrared scanning device and the emergency dispatching device are jointly activated; if it is determined that the camera acquisition device is abnormal, the standby camera acquisition device and the emergency dispatching device are jointly activated.

[0022] Furthermore, multiple camera acquisition devices are installed, and multiple infrared scanning devices are installed.

[0023] Furthermore, it also includes a light intensity detection device and a light adjustment device;

[0024] The light intensity detection device is used to detect the light intensity of the carriage. When the camera acquisition device collects the passenger flow data of the target carriage, if the light intensity does not reach the preset light intensity value, the light adjustment device adjusts the light intensity to the preset light intensity value.

[0025] Furthermore, it also includes a camera direction detection device, which is used to detect the camera direction of the camera acquisition unit;

[0026] It also includes a camera direction adjustment device, which is used to adjust the camera direction of the camera acquisition device;

[0027] When the camera acquisition device collects the passenger flow data of the target carriage, if the camera direction does not match the preset camera direction, the camera direction adjustment device adjusts the camera direction of the camera acquisition device to the preset camera direction.

[0028] Furthermore, it also includes a scanning direction detection device, which is used to detect the scanning direction of the infrared scanning device;

[0029] It also includes a scanning direction adjustment device, which is used to adjust the scanning direction of the infrared scanning device;

[0030] When the infrared scanning device collects the passenger flow data of the target carriage, if the scanning direction does not match the preset scanning direction, the scanning direction adjustment device adjusts the scanning direction of the infrared scanning device to the preset scanning direction.

[0031] Further, both the camera moving device and the infrared moving device are electric slide rail assemblies.

[0032] A method for monitoring and analyzing the passenger flow situation in a vehicle uses a device for monitoring the passenger flow situation in a vehicle as described above to monitor and analyze the passenger flow situation in the vehicle.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] One of the beneficial effects of this solution is that both the first passenger flow data and the second passenger flow data are the passenger flow data of the same target carriage, but the data acquisition sources are different, and they can be used as verification data for each other. Moreover, the infrared scanner is a low-cost device, which can effectively avoid the cost and accuracy problems of traditional methods. By comparing and analyzing the first passenger flow data and the second passenger flow data, the area where the data does not match can be locally located, so as to locate the dead corner of data acquisition, that is, the dead corner of data acquisition that is inevitable in a single data acquisition method, which can be obtained by comparing and analyzing the two data acquisition methods. The data acquisition dead corners of the two can be overcome through the camera moving device and the infrared moving device, so as to obtain accurate passenger flow data. If the passenger flow data collected by the two still do not match after overcoming the data acquisition dead corners, it can be determined that there is an abnormal part in the data acquisition of the two, and it is necessary to judge the abnormal part of the data acquisition, that is, to further determine whether the data acquisition of the camera acquisition device is abnormal or the data acquisition of the infrared scanning device is abnormal. No matter what kind of abnormality, this solution is provided with spare devices. The spare devices are not turned on under normal circumstances, and only when the device with abnormal data acquisition is judged, the corresponding spare device is turned on, so that the passenger flow data acquisition can be continuously and accurately carried out without causing unnecessary power consumption. The spare camera acquisition device and the spare infrared scanning device are not installed in the corresponding areas of the camera acquisition device and the infrared scanning device under normal circumstances. Therefore, when the device with abnormal data acquisition is judged, the spare device needs to be dispatched to the corresponding area through an emergency dispatching device, so as to realize continuous, stable and accurate data acquisition of the passenger flow.

Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0040] The features and performance of the present invention will be further described in detail below with reference to the embodiments.

[0041] When using a camera unit for monitoring the passenger flow in a carriage, there is a contradiction between the input cost and the monitoring accuracy. That is, if the number of installed camera units is small, when the passenger flow is crowded, due to the crowding, the video image data collected by the camera unit is blocked, resulting in errors in subsequent video image recognition and inability to accurately reflect the monitoring data of the passenger flow in the carriage. If the number of installed camera units is large, although the monitoring accuracy of the passenger flow in the carriage is high, the cost increase caused by the camera unit is also a thorny problem. If a camera unit with lower quality is selected to reduce the cost, it will also cause problems with the monitoring accuracy of the passenger flow in the carriage.

[0042] As Figure 1 shown, a vehicle-mounted passenger flow monitoring device is proposed, including a camera acquisition device, an infrared scanning device, a local positioning device, a camera moving device, an infrared moving device, an abnormality judgment device, a standby camera acquisition device, a standby infrared scanning device, and an emergency dispatching device;

[0043] The camera acquisition device is used to collect the passenger flow data of the target carriage, denoted as the first passenger flow data;

[0044] The infrared scanning device is used to collect the passenger flow data of the target carriage, denoted as the second passenger flow data;

[0045] Both the first passenger flow data and the second passenger flow data are the passenger flow data of the same target carriage, but the data acquisition sources of the two are different, and they can be used as verification data for each other; moreover, the infrared scanning uses low-cost devices, which can effectively avoid the cost and accuracy problems of traditional methods.

[0046] The local positioning device is used to perform local positioning on the area where the first passenger flow data does not match the second passenger flow data; by comparing and analyzing the first passenger flow data and the second passenger flow data, the area where they do not match can be locally positioned, so as to locate the dead corner position of data acquisition, that is, the dead corner of data acquisition that is inevitable in a single data acquisition method can be obtained through the comparative analysis of the two data acquisition methods.

[0047] The camera moving device is used to move the camera acquisition device according to the local positioning;

[0048] The infrared moving device is used to move the infrared scanning device according to the local positioning;

[0049] Through the camera moving device and the infrared moving device, the dead corners of their data acquisition can be overcome, so as to obtain accurate passenger flow data.

[0050] The abnormality judgment device is used to judge whether the camera acquisition device and the infrared scanning device are abnormal; if after overcoming the dead corner of data acquisition, the passenger flow data collected by the two still do not match, it can be judged that there is an abnormal part in the data acquisition of the two, and it is necessary to judge the abnormal part of the data acquisition, that is, to further determine whether the data acquisition of the camera acquisition device is abnormal or the data acquisition of the infrared scanning device is abnormal.

[0051] The standby camera acquisition device is used to act when the camera acquisition device is abnormal;

[0052] The standby infrared scanning device is used to act when the infrared scanning device is abnormal;

[0053] Regardless of what kind of abnormality, this solution is provided with standby devices. The standby devices are not turned on under normal circumstances. Only when the device with abnormal data acquisition is judged, the corresponding standby device is turned on, so that the passenger flow data acquisition can be continuously and accurately carried out without causing excessive power consumption.

[0054] The emergency scheduling device is used to schedule the standby camera acquisition device to the camera acquisition device and schedule the standby infrared scanning device to the infrared scanning device.

[0055] Normally, the standby camera acquisition device and the standby infrared scanning device are not installed in the corresponding areas of the camera acquisition device and the infrared scanning device. Therefore, after the device with abnormal data acquisition is determined, the standby device needs to be scheduled to the corresponding area through the emergency scheduling device, so as to achieve continuous, stable and accurate data acquisition of the passenger flow.

[0056] Such as Figure 2 As shown, further, the camera acquisition device and the infrared scanning device are always on; the local positioning device, the camera moving device, the infrared moving device, the abnormal judgment device, the standby camera acquisition device, the standby infrared scanning device, and the emergency scheduling device are always off;

[0057] When the first passenger flow data does not match the second passenger flow data, the local positioning device, the camera moving device, and the infrared moving device are turned on;

[0058] When the camera moving device moves the camera acquisition device to local positioning, the passenger flow data collected is recorded as the first passenger flow inspection data; when the infrared moving device moves the infrared scanning device to local positioning, the passenger flow data collected is recorded as the second passenger flow inspection data; if the first passenger flow inspection data does not match the second passenger flow inspection data; then the abnormal judgment device is turned on;

[0059] If the first passenger flow inspection data matches the first passenger flow data and the second passenger flow inspection data does not match the second passenger flow data, the abnormal judgment device determines that the infrared scanning device is abnormal; if the first passenger flow inspection data does not match the first passenger flow data and the second passenger flow inspection data matches the second passenger flow data, the abnormal judgment device determines that the camera acquisition device is abnormal;

[0060] If it is determined that the infrared scanning device is abnormal, the standby infrared scanning device and the emergency scheduling device are jointly turned on; if it is determined that the camera acquisition device is abnormal, the standby camera acquisition device and the emergency scheduling device are jointly turned on.

[0061] In the above solution, the camera acquisition device, the infrared scanning device are always on, and the local positioning device, the camera moving device, the infrared moving device, the anomaly judgment device, the standby camera acquisition device, the standby infrared scanning device, and the emergency dispatching device cooperate and start in an orderly manner, which can avoid collecting a large amount of invalid data and reduce the power consumption of the entire monitoring device. Moreover, it can also ensure the accuracy of passenger flow data and the low cost of the monitoring device at the same time; when abnormal passenger flow data collection occurs, accurate positioning of the anomaly can be achieved, and continuous, stable, and accurate collection of passenger flow data can also be realized by dispatching standby components.

[0062] Furthermore, a plurality of the camera acquisition devices are installed, and a plurality of the infrared scanning devices are installed. The installed quantity of both can be adaptively installed according to the actual parameters of the target carriage.

[0063] Furthermore, it further includes a light intensity detection device and a light adjustment device;

[0064] The light intensity detection device is used to detect the light intensity of the carriage. When the camera acquisition device collects passenger flow data of the target carriage, if the light intensity does not reach the preset light intensity value, the light adjustment device will adjust the light intensity to the preset light intensity value.

[0065] In the above solution, it can effectively avoid errors in the subsequent actions of the entire monitoring device due to light intensity.

[0066] Furthermore, it further includes a camera direction detection device, and the camera direction detection device is used to detect the camera direction of the camera acquisition unit;

[0067] It also includes a camera direction adjustment device, and the camera direction adjustment device is used to adjust the camera direction of the camera acquisition device;

[0068] When the camera acquisition device collects passenger flow data of the target carriage, if the camera direction does not match the preset camera direction, the camera direction adjustment device will adjust the camera direction of the camera acquisition device to the preset camera direction.

[0069] In the above solution, it can effectively avoid errors in the subsequent actions of the entire monitoring device due to camera direction.

[0070] Furthermore, it further includes a scanning direction detection device, and the scanning direction detection device is used to detect the scanning direction of the infrared scanning device;

[0071] It also includes a scanning direction adjustment device, and the scanning direction adjustment device is used to adjust the scanning direction of the infrared scanning device;

[0072] When the infrared scanning device collects the passenger flow data of the target carriage, if the scanning direction does not match the preset scanning direction, the scanning direction adjusting device will adjust the scanning direction of the infrared scanning device to the preset scanning direction.

[0073] In the above solution, it can effectively avoid errors in the subsequent actions of the entire monitoring device due to the scanning direction.

[0074] Further, the camera moving device and the infrared moving device are both electric slide rail assemblies.

[0075] In the above solution, the electric slide rail assembly is used to quickly dispatch the above-mentioned spare parts.

[0076] A method for monitoring and analyzing the passenger flow situation on a vehicle uses a vehicle passenger flow situation monitoring device as described above to monitor and analyze the passenger flow situation on the vehicle.

[0077] The above are the preferred embodiments of the present invention. All changes made according to the technical solution of the present invention that do not exceed the scope of the technical solution of the present invention in terms of the functions and effects produced belong to the protection scope of the present invention.
