Problems solved by technology

The disadvantage of this remote locking method is that the reliability is very poor. When the construction machinery is in an area without communication signal, it cannot be locked, which increases the financial risk, which is unacceptable to the manufacturer or seller of construction machinery

Embodiment approach

[0038] Car lock can be implemented in one of the following three ways or a combination thereof: controlling the speed regulating motor to limit the engine speed, controlling the flameout solenoid valve to prohibit restarting, and limiting the mechanical working speed through the flow control solenoid valve.

[0039] Throttle control: The user adjusts the throttle knob, changes the adjustable resistance value, and then changes the voltage signal output to the P0.7 pin of the construction machinery controller. Input signal - direction of rotation (DIR+ / CCW+) and throttle adjustment (CP+ / CW+), output signal U, V, W to the motor to control the motor to add or subtract oil and the amount of oil added or subtracted.

[0040] LCD: The Load pin of the LCD controller is the enable pin, CLK is the clock signal input, Data is the data input, and the output of the controller is connected to each segment pin of the LCD.

[0041] Three locking methods:

[0042] 1. Reduce engine power

Abstract

The present invention provides a method and a device for the engineering machine code locking and unlocking, belongs to the controlling technology field, and is used in solving the equipment locking problem. The technical proposal is to use a control system composed of an engineering machine controller, a lock vehicle executing mechanism, a keyboard, and a displayer as the operation platform, to arrange a code memory in the engineering machine controller, to write the user unlock vehicle program executed automatically when the machine starts in the code memory and pre-store the unlocking code. By inputting the unlocking code in the keyboard, whether the input code is in accord with the pre-stored unlocking code can be judged by a CPU, when yes, the control executing mechanism finishes the locking execution or relieves the locking state on the engineering machine. The locking execution or the locking relieving refers to that the executing mechanism conducts the working state controlling on a speed adjusting motor, the flameout electromagnetism or the flux control proportion electromagnetism. The present invention can lock the engineering machine limberly and reliably, not only can reduce the financial risk of the manufacturer and the dealer, but also can provide users with convenience.

Description

technical field [0001] The invention relates to a method for locking construction machinery with a password, which belongs to the technical field of control. Background technique [0002] Construction machinery is generally complex in structure and expensive, so it is often sold on the basis of mortgage and installment payment. Manufacturers or sellers of construction machinery require construction machinery to have a locking function in order to control overdue construction machinery and reduce financial risks. In addition, in order to prevent the construction machinery from being stolen or started by non-owner drivers at will, it is also necessary for the construction machinery to have a reliable locking function. At present, a more reasonable locking method for construction machinery is to use a remote monitoring computer to send a lock or unlock signal, which is transmitted to the remote monitor of the construction machinery through the Internet and wireless communicati...
