[0032] In some embodiments, the camera module 101 includes a first camera and a second camera, and the first camera and the second camera are configured to acquire video images of the target driver from different directions.

[0033] Specifically, the first camera and the second camera can fully and effectively obtain the driver's video image, providing sufficient data for behavior recognition.

[0034] In some embodiments, the video recognition module 102 has a pre-stored behavior recognition program.

[0035] In some embodiments, the behavior recognition program is an existing commercially available recognition software or an open source recognition program.

[0039] In some embodiments, the alarm module 105 includes a first alarm device, which is disposed in a cab where the target driver is located.

[0040] In some embodiments, the first alarm device includes an audible and visual alarm.

[0041] The first warning device is used to remind the driver on site and correct the driver's distraction or other abnormal behavior in time.

[0043] The input end of the signal transmitter is connected to the first output end of the processor chip 104 , the signal transmitter is in communication connection with the signal receiver, and the output end of the signal receiver is connected to the input end of the second alarm.

[0044] In some embodiments, the signal receiver and the second alarm are arranged in a monitoring room corresponding to the rail operation vehicle.

[0048] Optionally, the second data transmission module uploads the driver's behavior to a host computer for storage or further analysis.

[0049] The driver behavior monitoring device provided in the embodiment of the utility model is equipped with a rail operation vehicle driver abnormal behavior monitoring device to perform online identification and alarm reminders of abnormal behaviors of the driver such as fatigue, line of sight deviation, making or receiving phone calls during driving, so as to effectively regulate the driver's driving behavior and improve the operating safety of the rail operation vehicle.

[0050] Embodiment 2

[0051] On the other hand, an embodiment of the present utility model provides a rail working vehicle, which includes the driver behavior monitoring device as described above.

[0052] Figure 2 Another structural schematic diagram of the driver behavior monitoring device provided by an embodiment of the utility model is shown.

[0053] See also Figure 2 The driver behavior monitoring device includes a driver behavior recognition host, an intelligent camera, and a voice speaker.

[0054] The driver behavior recognition host has a pre-stored video recognition algorithm, which can identify abnormal behaviors such as driver fatigue, line of sight deviation, and making or receiving phone calls at the front end.

[0058] The driver behavior monitoring device provided by the embodiment of the utility model can effectively monitor and warn the abnormal behavior of the driver of the railway track operation vehicle by combining video images and the driving status of the locomotive, thereby ensuring the safety of driving operations.

[0059] Embodiment 3

[0060] The following is an example of the operation of the driver behavior monitoring provided by the embodiment of the utility model.

[0061] In a specific example, the smart camera and the voice speaker are respectively installed directly in front of the driver, and the driver behavior recognition host is fixed near the control console of the rail operation vehicle.

[0062] The intelligent camera collects the driver's front head information in real time, and the driver's behavior recognition footprint performs intelligent analysis and processing on the video image information, by identifying and counting the driver's fatigue, line of sight deviation, and making or receiving phone calls.

[0063] For example, if the driver closes his eyes or squints for 5 seconds, he is judged as driving while fatigued; if it lasts for 10 seconds, he is judged as driving with moderate fatigue; and if it lasts for 15 seconds, he is judged as driving with severe fatigue.

[0064] If the driver uses the mobile phone to make or receive a call and the duration exceeds 1 second, it will be judged as the driver making or receiving a call.

[0065] If the driver behaves abnormally while the vehicle is driving, the driver behavior recognition host will promptly remind the driver through the voice speaker.

[0066] Furthermore, combined with the vehicle operation status information such as running, parking, speed, etc. fed back by the vehicle control system, auxiliary decision-making is carried out for the driver's abnormal behavior identification scenario. The online monitoring results are sent to the ground platform through the data transmission management module to perform statistical management of the driver's abnormal behavior.
