The sensor is replaced by the camera, the installation and debugging of the sensor are avoided, the complexity of the tower crane jacking monitoring system is reduced, and the use is facilitated.

[0033] In some embodiments, the monitoring module comprises an intelligent gateway and a switch, the signal output ends of the plurality of cameras are respectively connected with the signal input ends of the switch, and the signal output end of the switch is connected with the signal input end of the intelligent gateway.

[0034] In the embodiment, the switch can be a power over Ethernet (POE) switch or other switches, wherein the POE switch refers to a switch capable of providing network power supply for a remote power receiving terminal through a network cable, and the POE switch integrates the functions of a network switch and a POE power supply. The POE switch can be responsible for providing network and power supply for all cameras and saving the pictures captured by all cameras as evidence of the jacking process.

The intelligent gateway can be equipped with a CPU and an NPU, respectively responsible for the logic processing of the whole system and the image visual processing of the camera. The intelligent gateway and the switch can be arranged in a cabinet to reduce damage.

[0035] The intelligent gateway and the switch are arranged in the monitoring module, the signal output ends of the plurality of cameras are respectively connected with the signal input ends of the switch, the signal output end of the switch is connected with the signal input end of the intelligent gateway, each camera is connected with the intelligent gateway through the switch, the work images captured by the camera are accurately transmitted to the intelligent gateway for image visual processing, so as to monitor the jacking process of the tower crane according to the work images of the jacking key points.

[0036] In some embodiments, a signal output end of the monitoring module is connected with a signal input end of the pump station of the tower crane.

[0037] The monitoring module is configured to generate an instruction and send the instruction to the pump station of the tower crane to control the pump station of the tower crane to be locked or unlocked.

[0038] In the embodiment, the monitoring module can generate an instruction in the monitoring process, which can be an instruction to lock or unlock the pump station of the tower crane. The pump station of the tower crane is locked or unlocked after receiving the instruction, thereby achieving control of the pump station during the jacking process of the tower crane. The locked pump station cannot be operated by the worker, thereby achieving restriction on the operation of the worker and effectively preventing accidents of the tower crane.

[0039] In some embodiments, the pump station of the tower crane comprises an intelligent bidirectional lock and a pump station operating device. A signal input end of the pump station operating device is connected with a signal output end of the intelligent bidirectional lock. A signal input end of the intelligent bidirectional lock is connected with a signal output end of the monitoring module. The intelligent bidirectional lock is configured to control the pump station operating device to be locked or unlocked according to the instruction. The pump station operating device is configured to acquire an operation instruction in an unlocked state and control the pump station of the tower crane according to the operation instruction.

[0040] In the embodiment, the bidirectional lock makes an action of whether to lock the pump station according to the instruction issued by the intelligent gateway. The intelligent bidirectional lock is a lock with data processing capability. The pump station operating device can be a pump station operating handle. The worker can control the pump station through the pump station operating handle. By arranging the intelligent bidirectional lock and the pump station operating device, the intelligent bidirectional lock controls the pump station operating handle to be locked or unlocked according to the instruction after receiving the instruction.

With the pressure sensor, the intelligent bidirectional lock can make an action according to the cylinder pressure, for example, in the case of prohibiting the cylinder load, the intelligent gateway issues an instruction of prohibiting the cylinder load to the intelligent bidirectional lock. The intelligent bidirectional lock further judges the cylinder pressure in the case of the instruction, and can be locked when the cylinder pressure reaches a preset value.

[0043] Through the pressure sensor, the intelligent bidirectional lock can act according to the cylinder pressure, so that the intelligent bidirectional lock is more intelligent and reliable.

[0044] In some embodiments, an alarm device is further included, and a signal input end of the alarm device is connected with a signal output end of the intelligent bidirectional lock.

[0045] In the embodiment, the alarm device can be an audible and light alarm device, a voice alarm device, etc. For example, the alarm device can be a loudspeaker, which can be installed near the pump station. The intelligent bidirectional lock can send a signal to the loudspeaker to remind the construction workers near the pump station whether the pump station is locked.

[0046] In some embodiments, an input device is further included, and the monitoring module is connected with the input device.

[0047] In the embodiment, the input device can be connected to the monitoring module through a wireless (Wireless Fidelity, WI FI) or mobile communication network, such as a 5th-Generation Mobile Communication Technology (5G) network, to access the system homepage on the intelligent gateway to know the running state of the system, or to set the system to facilitate access and setting of the system on the intelligent gateway. The input device can be a keyboard, a touch panel, a smart phone, etc.

[0048] In some embodiments, the input device is a touch panel.

[0049] In the embodiment, the touch panel adopts a touch operation, which is very intuitive, and users can use it without complex learning, and the touch operation of the user can be quickly perceived and responded in time.

[0050] In some embodiments, the camera is a spherical camera.

[0051] In the embodiment, the spherical camera can rotate horizontally by 360° and vertically by a certain angle, so that the camera can cover a very large monitoring area. Compared with a fixed-angle camera, the spherical camera reduces the monitoring blind area, so that the working images of the jacking key points can be obtained more flexibly and accurately, which helps to improve the jacking monitoring accuracy of the tower crane.

[0052] In some embodiments, the plurality of cameras includes a first camera, a second camera, and a third camera, the first camera is arranged on a ladder of an upper installation part of a shaft plane of the highest standard section of the tower crane, the second camera is arranged at the bottom of a walking net of the upper installation part of the tower crane, and the third camera is arranged on a cross beam of the tower crane.

[0053] In the embodiment, the first camera can be used to monitor whether the upper pin shaft, tenon and lifting frame are hung in, the second camera can be used to monitor whether the lower pin shaft, support rod point and lifting frame are introduced, and the third camera can be used to monitor the cross beam safety pin shaft and oil cylinder, so that the monitoring of all jacking key points can be realized through the three cameras, the cost is saved, and the complexity of the tower crane jacking monitoring system is further reduced.

[0054] The scheme will be described below with specific examples:

[0055] For small and medium-sized tower cranes, three spherical cameras can be arranged to monitor all jacking key points. The first spherical camera is located on the upper pin shaft plane of the highest standard section and is fixed on the climbing ladder of the upper part. The spherical camera can monitor whether the four upper pin shafts, four tenons and the lifting frame are hung in through the rotation of its own viewing angle. The second spherical camera is located at the bottom of the walking net of the upper part. The viewing angle is downward to monitor whether the four lower pin shafts, two support rod points and the lifting frame are introduced. The third spherical camera is located on one side of the cross beam and can be magnetically attached to the cross beam to monitor the two cross beam safety pin shafts and the oil cylinder. During the jacking operation of the tower crane, the intelligent gateway reads the camera pictures on the switch according to the jacking steps, runs the AI visual recognition algorithm to judge whether the relevant key points are executed in place. If a point is executed in place, the spherical camera is automatically driven to the next relevant key point for inspection. When all the relevant key points are checked, the pump station is unlocked to allow the worker to operate the oil cylinder jacking. If it is not executed in place, the corresponding point alarm will be issued through the loudspeaker, and the pump station will be locked to prevent operation, so as to prevent the occurrence of tower crane accidents.
