The invention provides a machine room inspection and supervision method and system based on track coverage. The method comprises the following steps: acquiring real-time video streams of a plurality of monitoring cameras deployed in a machine room inspection area; analyzing each frame of image of the real-time video stream by using a pre-trained visual target detection model, identifying an inspector target in the image, and determining a detection frame and pixel coordinates of the inspector target in an image coordinate system; executing a target position mapping step, and converting pixel coordinates of the inspector target in different monitoring camera images into plane graph coordinates on a machine room electronic plane graph based on a predefined coordinate mapping relation; a multi-view track merging step is executed, space-time fusion is carried out on plane graph coordinates from different monitoring cameras, and a continuous moving track of the inspection personnel on the electronic plane graph is generated; and executing inspection supervision based on the continuous moving track, and judging whether the inspection work of the inspector meets a preset requirement or not.

The utility model discloses a rear oxygen sensor wire harness fixing support which comprises a middle plate, the two ends of the middle plate are rotationally connected with mounting plates, a vertical plate is arranged on one side of the upper surface of the middle plate, and a movable plate which is distributed opposite to the vertical plate and can reciprocate in the length direction of the middle plate is arranged on the other side of the upper surface of the middle plate. And a screw rod is fixedly mounted at the top end, located on one side of the vertical plate, of the movable plate, and the end of the screw rod penetrates through the vertical plate and is in threaded connection with a nut. Due to the fact that the middle plate is rotationally connected with the two installation plates, the angles of the middle plate and the installation plates can be adjusted conveniently according to the installation environment and requirements, the requirement for the installation position is lowered, and installation is more convenient.

The invention relates to the technical field of bathroom accessories, in particular to a sterilization toilet stool which comprises a toilet stool body, a water tank, a water inlet valve and a water outlet valve, the water inlet valve and the water outlet valve are arranged in the water tank, the water inlet valve is provided with a water supplementing pipe, the water outlet valve is provided with an overflow pipe, and the water supplementing pipe is connected to the overflow pipe to supply water to the toilet stool body through the overflow pipe to form water seal; the sterilization device further comprises a sterilization gas supply device which comprises a gas inlet pipe for sterilization gas to penetrate through, the gas inlet pipe is connected to the overflow pipe, and the sterilization gas supply device is used for supplying the sterilization gas to the overflow pipe through the gas inlet pipe. Therefore, the sterilizing gas and the water from the water replenishing pipe converge and are mixed to supply sterilizing water to the toilet bowl body. Sterilization water is supplied to the sewage discharging cavity of the toilet bowl body through the flushing water channel, so that the flushing water channel and the sewage discharging cavity of the toilet bowl body are sterilized, bacteria are prevented from breeding in the toilet bowl body, and the toilet bowl is prevented from becoming a pollution source of germs.

The application discloses a low-power consumption passenger information automatic detection device and a vehicle with the device. The device comprises an identification card and a card reading device. The card reading device is used for reading passenger personal information in the identification card. The card reading device comprises a low-frequency trigger module, a wireless communication module, a motion sensing module and an MCU.
