specific Embodiment approach 1

[0018] Specific implementation mode one: the following combination figure 1 and figure 2 Describe this embodiment, the anti-disassembly method of the tower crane operation state management and tracking controller described in this embodiment, the anti-disassembly method is realized by the internal logic of the tower crane controller PLC, the anti-disassembly method receives the management and tracking The lifting control signal sent by the controller starts;

[0019] Connect the lifting control signal pin of the DSP of the management and tracking controller to the lifting control signal interface of the tower crane controller PLC. After the management and tracking controller receives the lifting control signal Qs sent by the tower crane operating platform, The hoisting control signal pin of the DSP generates the hoisting control pulse signal Qs1, the hoisting control pulse signal Qs1 is active at high level, after the hoisting control signal interface of the tower crane cont...

specific Embodiment approach 2

[0025] Specific implementation mode two: the following combination figure 1 and figure 2 This embodiment is described. This embodiment further describes the first embodiment, and the continuation of the predetermined period is realized by timing of a timer.

[0026] Instructions for anti-disassembly of tower crane operation state management and tracking controller:

[0027] The usual operating states of tower cranes are three types: lifting, luffing and slewing, and each type of operation has a gear limit, and they all gradually rise from lower gears to higher gears. After the first gear is restricted, the tower crane will not be able to operate, and the present invention is designed based on this principle.

[0028] First, select three IO pins in the DSP of the tower crane operation status management and tracking controller to connect with the interfaces of the hoisting, turning, and amplitude input signals of the tower crane controller PLC respectively. The three IO pins ...

Abstract

The invention belongs to the field of tower crane dismantling prevention and provides a dismantling prevention method for a tower crane operating state management and tracking controller in order to solve the problem that in the tower crane leasing process, since a tower crane cannot be controlled by a leaser, the overdue tower crane is still used by a leasee and not returned in time. The dismantling prevention method is realized through internal logic of a tower crane PLC; when the management and tracking controller receives a hoisting control signal Qs sent by a tower crane operating desk, a hoisting control signal pin of a DSP produces a hoisting control pulse signal Qs1, the tower crane controller enables a Qzj2 to be normally open through self-locking, the Qzj2 and the hoisting control pulse signal Qs1 control the on-off state of a Qzj3 in the tower crane PLC simultaneously, and the Qzj3 continues to keep the normally-open state within a predetermined period and then enters a normally-closed state; meanwhile, a Qs is a high level, the Qzj2 is in a normally-open state, and the tower crane PLC goes into a working state. The method is used for preventing the tower crane operating state management and tracking controller from being dismantled.

Description

technical field [0001] The invention relates to an anti-disassembly method for tower crane operation state management and tracking controller, and belongs to the technical field of tower crane anti-disassembly. Background technique [0002] With the rapid development of industry, tower cranes are more and more widely used in various fields. Some industries or short-term construction units do not want to buy tower cranes due to financial considerations, but want to choose short-term leases. Therefore, various tower crane companies have opened up leasing business for such users. However, the following problems generally exist when the tower crane is leased: [0003] 1. The location of the leased tower crane is unknown, and the construction party can still operate as usual even if the construction party fails to renew the fee within the time limit, which will bring economic losses to the tower crane rental company: [0004] At present, the agreement between the construction p...
