Equipment authorization method, device and system

Abstract

The invention provides an equipment authorization method, device and system. The method comprises the following steps that: an authorization device transmits an equipment serial number and / or GPS (Global Position System) identifier of target equipment to a management system through a network; the management system determines a matched first equipment identification code and transmits the matched first equipment identification code to the authorization device according to the equipment serial number and / or GPS identifier; the authorization device receives the first equipment identification code and stores the first equipment identification code; when the authorization device is connected with the target equipment, the authorization device transmits the stored first equipment identification code to a controller of the target equipment; the controller judges whether the first equipment identification code is matched with a second equipment identification code stored in the controller or not; and when the first equipment identification code is matched with the second equipment identification code, the authorization device performs authorization operation on the target equipment according to authorization information. Through adoption of the equipment authorization method, device and system, authorization operation of the equipment can be realized under the situation that GPS signal intensity is low or GPS signals are unavailable or the equipment is not provided with any GPS module.

Description

technical field [0001] The present invention relates to the technical field of equipment control, in particular to an equipment authorization method, device and system. Background technique [0002] At present, large-scale equipment mainly relies on GPS (Global Position System, Global Positioning System) to perform operations such as positioning, locking or unlocking equipment, and only the manufacturers of these equipment can perform the above-mentioned operations, while the customers who lease the equipment cannot perform the above-mentioned operations. This technology is mainly used in leased equipment and unpaid equipment to realize the controllability of the equipment, provide technical assistance for the recovery of project funds and payment, and at the same time avoid malicious changes to some electrical systems of the equipment and hide the behavior of the equipment. The equipment mentioned here may include pump trucks, vehicle pumps, cranes and other large equipment...
