Abstract

The invention discloses an energy-saving operating method for a satellite positioning communication terminal of engineering machinery, which belongs to the field of the satellite positioning communication terminal. The method comprises the following steps that: a first switch K1 and a second switch K2 on a receiver and a wireless transceiver module of a satellite positioning system respectively control the on / off state of corresponding power supplies, and a central processing unit judges the on / off state of the switch K1 and the switch K2 according to CAN bus data received by a CAN transceiver, a preset time value in a storage unit and a cumulative time value in a timer, so that a satellite positioning communication terminal can enter different operating modes, i.e. a normal mode, a power-saving mode or a fixed transmission mode. The method reduces the energy loss of the satellite positioning communication terminal, prolongs the operating time of the satellite positioning communication terminal, and not only satisfies the operating characteristics of the engineering machinery, but also meets the needs for positioning and remote monitoring of the engineering machinery and equipment.

Description

technical field [0001] The invention relates to the field of satellite positioning communication terminals, in particular to an energy-saving operation method of a satellite positioning communication terminal used for engineering machinery. Background technique [0002] Satellite positioning system is widely used in vehicle navigation, engineering survey, aviation rescue and municipal planning with its global, all-weather, high efficiency and other significant advantages. The satellite positioning system can provide real-time, high-precision three-dimensional coordinates, speed and time information, and the error does not accumulate over time. The degree of automation of the receiver of the satellite positioning system is getting higher and higher, and the operation is simple, which greatly reduces the workload and labor of the measurement. strength. The satellite positioning systems currently in operation mainly include the Global Positioning System (GPS) of the United Sta...
