Description

Technical Field

[0001] The utility model relates to the field of urban rail transportation, in particular to a novel subway train data integration and acquisition device. Background Art

[0002] In recent years, my country's national economy has continued to develop, and the living standards of urban residents have continued to improve. At the same time, the urban rail transit industry has developed rapidly, and more and more urban residents have participated in the urban rail transit system. The increase in passenger flow is bound to cause congestion problems, which will affect the comfort and safety of passengers, reduce the efficiency of train driving, and increase passenger risks. Therefore, real-time acquisition of relevant data to determine the train congestion is of great significance for adjusting the subway train passenger transport plan, ensuring the safety of subway train driving, improving the subway service level, and improving the utilization rate of train transportation capacity.

[0003] According to the published patent 201921431615.4, a front-end sniffing device for detecting the congestion of a subway train includes a first shell and a second shell arranged above the first shell, a USB interface is arranged on the side of the first shell, the first shell has a built-in card-type computer connected to a Wi-Fi probe module, a wireless data transceiver module, and a video module, a Csi interface is arranged on the card-type computer inside the first shell, the second shell has a built-in video storage module connected to a camera, and the camera is fixed above the second shell. The utility model is suitable for front-end data collection of subway train congestion. Compared with the existing collection device, it has the advantages of low cost, small size, light weight and good stability. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although there is a high-definition camera supporting the USB interface, the manager can call any device installed in the car to view the degree of congestion in the car in real time and dynamically, which plays a role in verification. During use, the traditional subway train data integration collection device generally uses a camera to count the number of people, but the size of different people is different. It is actually inaccurate to simply count the occupied area of ​​the car by counting the number of people. Moreover, there are different numbers of people in different positions inside the car, and it is difficult for traditional cameras to count and identify the number of people in different positions in the car. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a new type of subway train data integration and collection device to solve the current traditional subway train data integration and collection device, which generally uses a camera to count the number of people. However, the size of different people is different. It is actually inaccurate to simply rely on counting the number of people to count the occupied area of ​​the carriage. Moreover, there are different numbers of people at different positions inside the carriage. It is difficult for traditional cameras to count and identify the technical problem of the number of people at different positions in the carriage.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a new type of subway train data integration collection device, including a fixed disk body, and also including:

[0006] A fixed block, installed at the bottom of the fixed plate;

[0007] The collection mechanism is installed on both sides of the bottom of the fixed block. The collection mechanism includes a number recognition camera and a three-dimensional camera.

[0010] Preferably, a device housing is fixed on the top of each of the first fixing plate and the second fixing plate, a limiting rod is fixed on the top between the first fixing plate and the second fixing plate, and a connecting block passes through one side of the limiting rod.

[0011] Preferably, circular grooves are provided on both sides of the top of the device housing, and air sensors are installed inside the circular grooves.

[0012] Preferably, square holes are provided at both upper and lower ends of the device shell, an air filter is installed inside the square hole, a motor is installed at the bottom end of the device shell, a motor shaft is connected to the top of the motor, and an exhaust fan blade is installed on the top of the motor shaft.

[0013] Preferably, a square groove is provided in the middle of the bottom end of the fixing block, and an LED lamp tube is installed inside the square groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model combines a fixed disk, a number recognition camera and a three-dimensional camera. In the process of identifying the number of people in the carriage, the number recognition camera can be used for recognition. At the same time, since a three-dimensional camera is also provided, the area occupied by the people in the carriage can be three-dimensionally recognized when identifying the number of people. The number of people is combined with the three-dimensional data, so that the staff can more accurately judge the degree of crowding in the carriage. Moreover, after the device shell is installed on the top of the carriage, the positions of multiple cameras for collection can be adjusted through threaded rods, which is convenient for identifying different positions in the carriage, thereby improving the adjustability of the device and solving the problem that traditional subway train data integration and collection devices generally use cameras to count the number of people, but the size of different people is different. It is actually inaccurate to simply rely on counting the number of people to count the occupied area of ​​the carriage. Moreover, there are different numbers of people at different positions inside the carriage, and it is difficult for traditional cameras to count and identify the number of people at different positions in the carriage.

[0016] 2. The utility model combines an air sensor, an air filter and exhaust fan blades. An air sensor is arranged on the top of the device shell and is connected to the subway's on-board computer. The air in the car can be detected in real time. When the air detection value is poor, the on-board computer will control the motor to start, thereby drawing the air in the car into the device shell, and circulating the air through the air filter, thereby automatically purifying the air in the car.
