Detailed Description

As shown in fig. 1, the video monitoring device for the engineering truck comprises a host, a camera and a PIR (PIR: human body detection sensor). The host and the PIR adopt a Bluetooth communication mode, and the host and the camera adopt a data line (the data line can provide a working power supply for the camera) connection mode.

The main machine is arranged in a cab of the engineering truck, the PIR is arranged at the position with the height of 1.5-2.0 m outside the engineering truck, and the camera is arranged in the cab or the position with better visual field outside the cab.

The camera is provided with a plurality ofly, installs the place at needs inspection scene, adopts four cameras in this embodiment, installs at the driver's cabin top, monitors four directions respectively. The camera adopts magnetism to inhale the gluey mounting means of +3M, simple to operate.

The camera is mainly responsible for the video audio acquisition of job site to record and keep relevant evidence under emergency, and support infrared night vision function.

The camera collects images through a built-in Sensor board, carries out coding processing through Haimai to form H264 video stream, and transmits the H264 video stream to the host through a network.

The camera adopts haisi Hi3516 chip, based on embedded linux system, adopts H264 coding technology, can realize 1080P's video recording and full size and shoot, and the video stream includes preview, video recording, stream transmission.

The PIRs are arranged in a plurality of uniformly distributed outside the engineering truck and are responsible for detecting human bodies. In the embodiment, 4 engineering trucks can be arranged at most, and 360-degree detection of the engineering trucks can be realized (actually, each detection angle is 120 degrees, and 4 engineering trucks are installed in consideration of the shape and the actual installation environment of the engineering trucks). PIR adopts 3.3v button cell power supply, and normal use can satisfy two years time. PIR mainly includes bluetooth chip and PIR sensor, and the bluetooth chip includes bluetooth master module and the bluetooth slave chip of being connected with it, and bluetooth chip and PIR sensor adopt GPIO communication, and when the PIR sensor detected the human body, can trigger a level pulse, and level pulse can be caught by bluetooth slave chip, and bluetooth slave chip can give this level pulse for the bluetooth master module, and the bluetooth master module does corresponding action.

When the PIR is used, a signal can be transmitted to the host through the Bluetooth, the host controls the camera to start recording, and meanwhile, the alarm equipment starts to give an alarm and uploads the alarm to the background to inform the host; the host and the camera are connected in a network cable mode and used for transmitting data and power, the camera collects field images and sound, the field images and the sound are recorded and stored in real time (a storage TF card is arranged inside the field images and the sound is stored), and image information is uploaded to a background if needed according to judgment of the host.

The host computer comprises a 4G board and a main board, and the 4G board is connected with the main board through a USB port.

The 4G board is provided with a 4G module, a GPS module and a Bluetooth module and is mainly used for 4G communication, GPS positioning and Bluetooth communication; the mainboard is provided with a Haesi main processor Hi3536 and an MCU, and the Haesi main processor Hi3536 and the MCU are connected through a serial port for communication. The Haesi main processor mainly processes audio and video related and communication related technologies and is used for processing camera data, background instructions, driving a 4G module and the like; the MCU is used for managing the gyroscope, managing the Bluetooth and positioning the GPS.

The utility model discloses when engineering machinery equipment worked, host computer and camera were in operating condition, and the real-time video recording to can make statistics of equipment working hour, location and check out test set gesture, man-hour and equipment position, gesture are passed through 4G communication and are sent to the backstage, and the owner can look over at the cell-phone end at any time, and at this moment, PIR is in dormant state; when the engineering mechanical equipment stops working, the PIR is awakened, and meanwhile, the host and the camera are in a low power consumption state, when a human body approaches, the PIR can detect the human body and is triggered to notify a low power consumption management system in the host, the low power consumption management system starts the camera and the host immediately to carry out on-site shooting, and simultaneously notifies the host immediately, so that the anti-theft purpose is achieved; similarly, a similar signal is triggered when there is an abnormal shock. In the system, the host, the camera and the PIR cooperate with each other to complete the supervision and protection of the engineering mechanical equipment.
