Problems solved by technology

The disadvantage of this control method is that it is very easy to be destroyed by man-made. If you want to release the locked state, you only need to short the contacts of the relay with wires. Therefore, this method cannot achieve reliable locking of engineering equipment.

Embodiment Construction

[0020] The following three locking methods are further described in detail:

[0021] 1. Reduce engine power

[0022] Ordinary engine throttle adjustment logic: as shown in Figure 2, the driver dials the hand throttle dial, the hand throttle output voltage value at the sliding end of the hand throttle potentiometer W changes, and the engineering equipment controller U3 controls the output to adjust according to the level of the hand throttle voltage. The signal of the speed motor M is used to control the action of the speed regulating motor, and control the fuel supply rod of the engine fuel injection pump to move in the direction of refueling or reducing fuel, so as to achieve the purpose of accelerating or decelerating the engine.

[0023] In Fig. 2, the engine 2 is an ordinary fuel injection pump engine. When the engine power needs to be reduced, the remote monitor 1 sends an engine lock command to the engineering equipment controller U3 through the communication line, and t...

Abstract

A remote engineering equipment and unlock the lock, a control technology, remote locking used to solve the problem. Its technical programmers are: remote monitoring centre from its computers, wireless communication networks, remote monitoring, engineering equipment and the implementation of the controller comprising a control system, remote monitoring from a central computer lock or unlock signal, the signal through the wireless transmitted to the communication network remote monitoring, remote monitoring via communication interface to send it to the controller engineering equipment, engineering equipment by the end of the controller implementation agencies to lock or unlock operation, the invention also provides a realization of this kind of locking devices. The present invention is not only easy to implement engineering equipment reliable remote lock or unlock, but also to prevent damage to the device unlock methods, and therefore effective security and greatly reduce financial risks.

Description

technical field [0001] The invention relates to a method for remotely locking engineering equipment, which belongs to the technical field of control. Background technique [0002] Engineering equipment is generally complex in structure and expensive, so it is often sold in the form of mortgage and installment payment. Manufacturers and sellers of engineering equipment need the remote locking function of engineering equipment in order to control overdue engineering equipment and reduce financial risks. In addition, in order to prevent engineering equipment from being stolen or started by non-owner drivers at will, it is also necessary for engineering equipment to have a reliable remote locking function. Existing remote locking of engineering equipment generally uses remote monitoring to realize locking control through relay contacts connected in series in the control loop. The disadvantage of this control method is that it is very easy to be destroyed by man-made. If you wa...
