Description

A kind of tower crane monitoring operation device

Technical field

The utility model belongs to electronic information field, is specifically related to a kind of tower crane monitoring operation device.

Background technology

Tower crane has become current indispensable hoist tool of building epoch, and its use has not only reduced a lot of manpower and materials, but also has improved building efficient.

But the use along with tower crane, also expose some safety problems, one of them subject matter is exactly the sight line problem in the chaufeur operation process, scene more complicated on the building site, shelter is more, the sight line of chaufeur is blocked often, if this moment, misoperation was easy to cause the generation of safety misadventure.Mainly be to tell particular case below the chaufeur by the staff on ground by interphone or flagman on the current building site, time and effort consuming so not only, in case and the verbal exposition mistake, will bring huge potential safety hazard.

Summary of the invention

The utility model provides a kind of tower crane monitoring operation device for the blind zone problem that solves driver's operation with to the height Issues of suspension hook.

The concrete technical scheme of the utility model is as follows:

A kind of tower crane monitoring operation device comprises laser rangefinder, camera, optical rotary encoder, sun-generated electric power, 3G wireless module and MCU control module; Described laser rangefinder, camera, optical rotary encoder, sun-generated electric power and 3G wireless module link to each other with the MCU control module respectively.

Described MCU control module is selected the S3C6410 microprocessor.

Described MCU control module is by 3G wireless module and operator's compartment display terminal and monitoring and control centre communication connection.

Described tower crane monitoring operation device is installed on the amplitude variation trolley by mechanical arm.

The beneficial effects of the utility model:

1. this control monitor unit is equipped with laser rangefinder, can get suspension hook apart from the height of ground and roof by Real-time Measuring, so that the measurement of elevation information is more accurate, has also improved the accuracy of driver's operation simultaneously.

2. on the amplitude variation trolley camera is installed, the situation on can the Real-Time Monitoring building site obtains suspension hook simultaneously apart from the elevation information of the scope of operation.

3. the data of camera and laser rangefinder collection are sent to monitoring and control centre, and so not only chaufeur can be seen the situation of tower crane operation, and the staff of monitoring and control centre also can carry out Real-Time Monitoring.

Description of drawings

Fig. 1 is the functional block diagram of this control monitor unit.

Fig. 2 is the communication functional block diagram of 3G module.

Fig. 3 is the schematic diagram of control monitor unit on tower crane.

Among the figure: the 1-control monitor unit; The 2-amplitude variation trolley; The 3-suspension hook; The 4-operator's compartment.

The specific embodiment

As shown in Figure 1, this control monitor unit 1 comprises laser rangefinder, camera, optical rotary encoder, solar cell, 3G wireless module, MCU control module, and the computing machine of operator's compartment display terminal and monitoring and control centre.Laser rangefinder, camera, optical rotary encoder, sun-generated electric power and 3G wireless module link to each other with the MCU control module respectively, and wherein the MCU control module is selected the S3C6410 microprocessor.

Mainly be divided into three steps in the time of control monitor unit work:

The first step, highly measure: (such as Fig. 3) this control monitor unit 1 is installed on the amplitude variation trolley 2 by mechanical arm, mechanical arm can all around swing, the laser that laser rangefinder is launched is received by apomecometer again after the reflection of object being measured, apomecometer is the round time of recording laser simultaneously, half of the product of the light velocity and turn-around time, be exactly that arm is apart from the height of the scope of operation, the mechanical arm that swings back and forth can be measured arm apart from the center-line-average of the scope of operation, can make like this altitude information more accurate, the measured error of avoiding the unfairness in building site to bring, measure the height that suspension hook 3 is transferred by optical rotary encoder, arm deducts the height that suspension hook 3 is transferred apart from the height of the scope of operation the most at last, obtains suspension hook 3 apart from the height of the scope of operation.

Second step, Real Time Monitoring: camera also is installed on the amplitude variation trolley 2, installs straight down, guarantee camera can be all the time operating area on the building site, below.Whole control monitor unit 1 uses protective cover to cover, to prevent that the inclement weathers such as sleet on the impact of equipment, are fixed on this control monitor unit 1 on the amplitude variation trolley 2, along with amplitude variation trolley 2 moves forward and backward, situation on the Real-Time Monitoring building site also obtains suspension hook 3 apart from the height of the scope of operation simultaneously.

The 3rd step, data transmission: the data that (such as Fig. 2) camera and laser rangefinder gather are through compressed encoding, after the video data encoder encapsulation, utilize the 3G functional module, carry out real-time Transmission by the video of Internet after to compressed encoding, the monitoring and control centre of site is connected to the Internet network by wireless router and carries out Real Time Monitoring, and the operator's compartment display terminal is connected on the wireless routing, thereby realizes Real Time Monitoring.So not only the operator's compartment staff can understand surface state and suspension hook 3 height in real time, can make staff's Real-Time Monitoring tower crane operation conditions of monitoring and control centre simultaneously, has improved the efficient of operation, has eliminated potential safety hazard.

The utility model tower crane monitoring operation device 1 is equipped with laser rangefinder, can get suspension hook 3 apart from the height of ground and roof by Real-time Measuring, so that the measurement of elevation information is more accurate, has also improved the accuracy of driver's operation simultaneously.On the amplitude variation trolley 2 camera is installed, the situation on can the Real-Time Monitoring building site obtains suspension hook 3 simultaneously apart from the elevation information of the scope of operation.The data of camera and laser rangefinder collection are sent to monitoring and control centre, and so not only chaufeur can be seen the situation of tower crane operation, and the staff of monitoring and control centre also can carry out Real-Time Monitoring.
