Abstract

The utility model discloses a remote fault diagnosis system of an excavator and belongs to the technical field of electronic detection. The remote fault diagnosis system of the excavator comprises a main controller, a GPS vehicle terminal, a monitor center, a monitor instrument, a signal acquisition module, an execution module, a black box and an engine control module, wherein the main controller is electrically connected with the GPS vehicle terminal, the monitor instrument, the signal acquisition module, the execution module, the black box and the engine control module respectively, and the GPS vehicle terminal is connected with the monitor center through a GPRS wireless network and an Internet network. The remote fault diagnosis system of the excavator is advantaged in that an operation state of each excavator can be timely known; a fault point of the excavator can be timely determined by carrying out remote analysis to operation parameters; and maintenance can be conveniently carried out.

Description

The excavator remote failure diagnosis system

Technical field

The utility model relates to a kind of fault diagnosis system, and specifically a kind of excavator remote failure diagnosis system belongs to the electric detective technology field.

Background technology

Development along with national economy, excavator is used widely, in abominable, the remote areas of environment such as exploitation of mineral resources, road construction, waterpower construction, often owing to have inconvenient traffic, the attendant can not check, repair in the scene of arriving in the very nick of time when machine goes wrong, can affect like this progress of engineering, cause great economic loss to the user.Often because fault can not in time be excluded, can affect the life-span of the use of excavator.

Summary of the invention

For the problem that above-mentioned prior art exists, the utility model provides a kind of excavator remote failure diagnosis system, can in time understand the running status of every excavator, is convenient to maintenance.

To achieve these goals, the technical solution adopted in the utility model is: a kind of excavator remote failure diagnosis system, comprise master controller, GPS car-mounted terminal, Surveillance center, monitoring device, signal acquisition module, execution module, black box, engine control module, master controller is electrically connected with GPS car-mounted terminal, monitoring device, signal acquisition module, execution module, black box, engine control module respectively, and the GPS car-mounted terminal is connected with Surveillance center with the Internet network by the GPRS wireless network.

Further, master controller is connected with GPS car-mounted terminal, monitoring device, signal acquisition module, execution module, black box, engine control module respectively by the CAN bus.

Principle of work: by the operational factor of signal acquisition module and engine control module collection vehicle, by the CAN bus transfer to master controller, master controller can be by the CAN bus transfer to the GPS car-mounted terminal, the GPS car-mounted terminal is by GPRS wireless network and Internet network, parameter is transferred to Surveillance center, the personnel of Surveillance center can carry out analyzing and processing to parameter by expert database, determine location of fault and degree, then by Internet network and GPRS wireless network failure code is sent to master controller, main control shows failure message at monitoring device, store in black box simultaneously.

The beneficial effects of the utility model are: the running status that can in time understand every excavator, and can be by the remote analysis to operational factor, in time determine the trouble spot of excavator, can not only improve attendant's work efficiency, reduce user's loss, work on after can also avoiding fault to occur, cause larger fault, prolong the serviceable life of excavator.
