Remote and local video monitoring vehicle-mounted device for construction machine

Abstract

The invention discloses a remote and local video monitoring vehicle-mounted device for a construction machine, mainly comprising a microcontroller based on a Linux system, a data acquisition input unit, an LCD (liquid crystal display) man-machine interaction interface, a 3G wireless communication module and a data storage device, which are connected with the microcontroller. The data acquisition input unit is responsible for acquiring working conditions and video data of the construction machine; the microcontroller processes the acquired data and outputs the acquired data to the man-machine interaction interface to be displayed, and the local video monitoring is realized; and the 3G wireless communication module establishes wireless connection with a remote monitoring center through TCP (transport control protocol) / UDP (user datagram protocol) network protocol and transmits large data volume such as video by adopting the hybrid mode of WCDMA (wideband code division multiple access) / GPRS (general packet radio service), so as to realize remote video monitoring. The remote and local video monitoring vehicle-mounted device for the construction machine has high level of integration and can realize remote and local video monitoring; meanwhile, a human face detection function is introduced to the local video monitoring and can carry out human face recognition on staff in the working range, an alarm signal can be transmitted initiatively, and the accident rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle-mounted monitoring of construction machinery, and in particular relates to a vehicle-mounted device for remote and local video monitoring of construction machinery. Background technique [0002] Since entering the 21st century, the state has put forward a series of policies to strengthen infrastructure construction such as railways, highways, electric power, water conservancy and hydropower, which has made my country's construction machinery industry present a trend of rapid development. Due to the high sales price of a single construction machinery, complex structure, unstable construction load, and harsh working environment, the failure rate is very high. Therefore, more and more attention has been paid to the working condition monitoring and fault diagnosis of construction machinery. At the same time, with the continuous improvement of wireless mobile communication technology and the improveme...

Problems solved by technology

[0003] At present, the vehicle-mounted monitoring devices for construction machinery in the market have the following deficiencies: ① Most of the monitoring methods are relatively simple, and cannot take into account both local monitoring and remote monitoring at the same time. Inconvenient; ② The information and data collected are relatively monotonous, mainly based on working condition parameters such as engine speed, fuel oil level, hydraulic oil temperature, cooling water temperature, etc., often ignoring the surrounding environmental factors of the actual work of construction machinery; ③ Not active in the surrounding environment Early warning function, when the operator is driving construction machinery, especially when reversing and turning the turntable, due to the high concentration of spirit and the limited field of vision, safety accidents are prone to occur; ④ For the remote monitoring system, data transmission based on GPRS network is generally used However, the actual data transmission speed of the GPRS network is only 40Kbit / s, which cannot solve the transmission of real-time large data volumes such as video, which makes the data received by the monitoring center seriously delayed, and the video display is incoherent, which cannot meet user needs.
