The invention relates to a system of transmitting running-state data of a remote grab through a GPRS network to a service center by GPS technique for processing and analyzing, composed of vehicle data collecting and transmission system, wireless network transmission system and service control system and its concrete executive steps as follows: 1. installing GPS devices and vechicle data collector on the vehicle; 2. transmitting the collected data through the GPRS network to the service center; 3. using the service control center to process and analyze the collected data; 4. diagnosing the failure and carrying out maintenance. The invention uses the GPS technique and GPRS network to transmit running-state data of the vehicle, finds the reason of the failure in the shortest time by data analysis and carries out maintenance in time, thus raising working efficiency, reducing the expenses and having greater social and economicbenefits.
Description
technical field [0001] The invention relates to a remote monitoring system, in particular to an excavator remote monitoring system. Background technique [0002] The excavator is a large-scale equipment with integrated control of machinery, electricity and hydraulics. Its structure is very complicated, and the data collection and monitoring of the control system are mainly completed by many secondary instruments. personnel for repairs. At the same time, due to the scattered use of construction machinery, it takes more time for maintenance personnel to travel to the construction site, which prolongs the maintenance time, reduces the utilization rate of equipment, and increases maintenance costs. Contents of the invention [0003] The purpose of the present invention is to provide a remote monitoring and fault diagnosis system for excavators to overcome the problems of difficult maintenance and high maintenance costs of existing excavators, so that the manufacturer can act...
