Problems solved by technology

Therefore, the ignition switch must have a unique lock cylinder, and the mechanical key must also have a unique tooth shape to unlock and prevent theft. However, this will bring huge production costs and troubles in operation.
Moreover, at present, the ignition switch and the key of most excavator factories are of the same specification, and do not have the anti-theft function.

Abstract

The invention discloses a remote control locking and unlocking system, a method and an engineering machine. The remote control locking and unlocking system is arranged on the engineering machine. The remote control locking and unlocking system comprises a remote control key used for sending an unlocking signal and a locking signal, a locking mechanism arranged on a door of a cab of the engineering machine, a host controller which is connected with the locking mechanism and is configured to receive the unlocking signal and the locking signal which are sent from the remote control key and control unlocking and locking of the locking mechanism according to the unlocking signal and the locking signal, and a starter which is connected with the host controller and is configured to start up and close down the engineering machine. Thus, the remote control locking and unlocking system, the method and the engineering machine can be adopted to reduce cost and raise antitheft performance, and are convenient for operation.

Description

technical field [0001] The present invention relates to the field of construction machinery, in particular to a remote control locking system and method, and construction machinery using the remote control locking system and method. Background technique [0002] At present, the ignition switch is mainly used on excavators to control power-on, start-up and flameout, and some ignition switches also have a preheating control function. Generally speaking, the ignition switch has three to four gears. By turning the matching mechanical key, different functions such as power-on and starting can be realized in different gears. [0003] At the same time, in order to realize the anti-theft function, the ignition switch and the mechanical key must correspond one by one, which is the same as the relationship between the household door lock and the key. Therefore, the ignition switch must have a unique lock cylinder, and the mechanical key must also have a unique tooth shape to unlock a...
