Abstract

The invention discloses a GPS / GIS (Global Position System / Geographic Information System)-based engineering machinery electronic controller. A CAN bus is connected with a main controller and a display controller, the main controller has all relay on-off output modules and accelerator motor control modules used for receiving operating signals in real time to control equipments to operate, and the display controller has a GPS / GIS wireless communication module and a keyboard display screen. A control method comprises the steps of receiving all working condition parameters by the main controller, and transmitting the GPS / GIS and the working condition parameters to a management center by the display controller; alarming when a positioning communication is abnormal; operating the equipment in time allowance, and relieving alarm after the communication is restored; carrying out the primary locking after exceeding the time limit, and operating an engine in an idling way; restoring the equipment in a locking time limit after contacting with a management center to obtain a password to unlock; carrying out secondary locking after the locking period exceeds, carrying out power failure and fuel cut for an entire vehicle, transmitting the password by a user after the user is in contact with the management center to confirm the equipment is in a good condition, and unlocking the equipment to restore operation. According to the GPS / GIS-based engineering machinery electronic controller provided by the invention, the position and operating condition of the equipment can be timely grasped by the management center, so as to effectively prevent stealing and damaging.

Description

technical field [0001] The invention relates to a construction machinery control system, in particular to a GPS / GIS-based construction machinery electronic controller and a control method. Background technique [0002] At present, construction machinery is widely used in infrastructure and production fields such as earthwork engineering, municipal engineering, road repair, farmland reconstruction, concrete crushing, pipeline laying, garden cutting and cultivation, and river dredging. According to statistics, by 2015, my country's construction machinery industry will Sales revenue will reach about 900 billion yuan, with an average annual increase of more than two digits. In terms of export, by 2015, the export of my country's construction machinery products will reach about 20 billion US dollars, becoming the world's largest exporter. However, the overall technical level of my country's construction machinery industry is still relatively backward, the level of manufacturing t...
