Problems solved by technology

[0004] In addition, in actual use, it is also found that the GSM signal coverage in some areas is very low, and the monitoring center cannot communicate with the remote monitoring device. When the machine is remotely locked by the monitoring center and moves to these areas, it cannot be remotely unlocked. In addition, it is no longer possible to remotely lock the machinery working in this area

Embodiment approach

[0028] The second implementation of the secondary lock shown in Figure 3: as shown in the figure, a pair of normally closed contacts J3-1 of the relay J3 are connected in series to the BR terminal of the start switch 5 to deliver voltage to the governor and the pump controller The situation in the line of the signal. One end of the coil of the relay J3 is connected to the P2.7 signal output port of the CPU of the remote monitoring device, and the other end is grounded.

[0029] The BR terminal of the starter switch controls the connection and disconnection of the entire vehicle circuit. When the machine needs to work, turn the start switch to connect the circuit of the BR terminal. During the machine work, the BR terminal of the start switch is always on. , you can turn the starter switch to disconnect the circuit of the BR terminal. Under normal circumstances, after the engine is started, the starter switch BR terminal provides a stable voltage signal to the governor and the...

Abstract

A multi-class locking-unlocking method and apparatus for engineering machiner features that the class-one and class-two locking-unlocking unit and the running signal feedback unit, which are installed to the engineering machinery, are connected with the remote monitor device and manual controller, which can transmit the class-one or class-two locking or unlocking instruction. Said apparatus is composed of the monitor circuit connected to the monitored object is engineering machinery, computer control circuit and transmission circuit.

Description

technical field [0001] The invention relates to a method for multi-stage automatic and manual locking and unlocking of a construction machinery remote monitoring device and a device thereof, belonging to the technical field of automatic control. Background technique [0002] Many of the currently used large-scale construction machinery with complex structures and expensive prices are equipped with remote information transmission devices to monitor the working conditions of the construction machinery and the state of the machinery itself. In actual use, on the one hand, it is necessary to lock the car to prevent non-drivers from driving the machine at will and to prevent car theft; on the other hand, because the price of the machine is relatively expensive, many of them are purchased in installments. , In order to recover the loan in time, it is also necessary to lock the car. Therefore, some vehicles use the function of the installed remote monitoring device to lock and unlo...
