Problems solved by technology

In this case, because the construction machine cannot send location information to the server of the management center, and the management center cannot know whether the construction machine is in the work area, the management center cannot determine whether to stop the operation of the construction machine
Even if the management center sends out an operation stop signal for stopping the operation of the construction machine, the construction machine cannot receive its operation stop signal, and quick measures to prevent theft cannot be taken

[0065] The management of the construction machine may be directly performed by its owner, however, for example, a method for having a management center owned by a manufacturer of the construction machine perform centralized management through a subcontract is also widely adopted. Also, in recent years, the method by which a contractor performing work receives a loan of a construction machine from a leasing company or a rental company has become more widespread. In addition, construction machine manufacturers or service companies that lead experienced repairers and the like generally perform maintenance such as repairs, inspections, and necessary repairs of construction machines. That is, contractors who actually operate construction machines and perform work, owners, managers, technical supporters who perform maintenance, and the like are all related to the construction machines. In an abnormal situation such as the theft of a construction machine, the owner and the manager wh...

[0097] with the help of Figure 6 to 9 describe the second embodiment in the case of applying the present invention to an anti-theft system of an oil hydraulic excavator.

[0098] Figure 6 is a block diagram of the anti-theft system in the second embodiment. In this system, information can be transmitted from a base station 240 located at a construction machine manufacturer or the like to an oil excavator (construction machine) 210 via a communication satellite 230 . The transmitted information includes information on the operable time range of the oil excavator 210, and the oil excavator 210 receiving the information takes its own anti-theft measures based on its information. The information on the operable time range is based on information from the communication device 250 such as the user owning the hydraulic excavator 210 . A specific structure will be described below.

[0099] Each hydraulic excavator 210 has a main control unit 211, a control unit 212 for communica...

Abstract

A security system of a construction machine of the present invention has a construction machine, a base station and a communication device. The construction machine comprises a data sending and receivingportion for sending first information, a storageportion for storing received information, and a control portion for controlling an operation of the construction machine. The base station receives the first information from the data sending and receiving portion of the construction machine and sends second information to the construction machine andmanages the construction machine. It is configured so that the communication device is connected to the base station through a communication network and can send third information to the construction machine through the base station.

Description

technical field [0001] The present invention relates to a system for managing the operating state of a construction machine such as an oil hydraulic shovel, and more particularly, to a construction machine capable of coping with an accident or theft by sending and receiving information using a portable communication device security system. Background technique [0002] There are frequent problems with construction machines being stolen from construction sites. Construction machines provided at a job site at a remote location typically remain on the job site during work. Such a work place is different from a storage place of construction machines supervised by an owner or a manager and anti-theft measures are insufficient, and the place becomes a place where theft easily occurs. [0003] An anti-theft device for an oil hydraulic excavator is disclosed in JP-A-9-50584. In this antitheft device, when a predetermined personal identification number is keyed in a key input devi...
