Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
A crane is a material handling apparatus, i.e. a multi-action hoisting machine which can vertically lift and horizontally handle heavy objects within a certain range, also called a navigation crane, a crane, etc. In the actual industry, the application is very wide.
Since the crane may have adverse effects on surrounding personnel due to the movement of its own components and the travel of the crane during handling of the weight, the safety protection of the crane is of great importance.
Currently, safety protection systems for cranes typically employ sensors to passively detect personnel or equipment in a work area. Specifically, the crane plans a travelling route in advance, then detects whether obstacles such as personnel or equipment exist on the travelling route through the sensor, and if the obstacles exist, the crane needs to be controlled to perform deceleration or stop moving so as to realize safety protection. The sensor for detecting an obstacle in the working area in the safety protection system may include, for example, a photoelectric sensor, a laser sensor, an ultrasonic sensor, and the like.
The safety protection system has the defects that the safety protection system can only passively detect the obstacle on the planned path, the movement needs to be decelerated or stopped under the condition that the obstacle exists, the work of the crane can be influenced to a certain extent, and the production efficiency of the crane is low. In addition, the detection of the obstacle by the sensor is also low in accuracy. For example, the photoelectric sensor and the laser sensor are easy to fail in a high-pollution and high-dust environment, the detection distance of the ultrasonic sensor is limited, the signal source is easy to diverge, and the like, so that the safety of the safety protection system is not high.
Based on this, the embodiment of the application provides a crane safety protection system to solve the above technical problems. The following describes embodiments of the present application with reference to the drawings.
Fig. 1 is a schematic structural diagram of a crane safety protection system provided in an embodiment of the present application, as shown in fig. 1, the crane safety protection system includes a crane 11, a control platform 12 and a personnel positioning device 13, and a positioning device 14 is disposed on the crane 11, wherein:
positioning means 14 for transmitting position information of the crane 11 to the control platform 12;
a person positioning device 13 for transmitting position information of a person to the control platform 12;
a control platform 12 for controlling the crane 11 to move based on the position information of the crane 11 and the position information of the person.
The crane 11 is typically moved within a predetermined area, which may be, for example, a shop, a worksite, etc. The crane 11 is a mechanism for carrying a weight, and a positioning device 14 for positioning the crane 11 is provided on the crane 11 to obtain position information of the crane 11 and send the position information of the crane 11 to the control platform 12.
In a preset area of movement of the crane 11, there may be certain personnel, such as personnel engaged in other work species, patrol personnel, etc. During the movement of the crane 11 within the preset area, there may be a situation in which the crane 11 is too close to the person, so that the person is in a disadvantageous environment, and thus, proper avoidance is necessary.
In the preset area, the crane safety protection system further comprises a personnel positioning device 13, wherein the personnel positioning device 13 can position personnel in the preset area to obtain the position information of the personnel and send the position information of the personnel to the control platform 12.

The UWB tag is carried on a person in a workshop working area, so that the position information of the UWB tag is the position information of the person. Thus, the UWB positioning base station, after acquiring the position information of the UWB tag, determines it as the position information of the person and transmits it to the control platform 12.

The positioning device 14 may be any one of a laser sensor, a rotary encoder, and a two-dimensional code band, or may include a plurality of the laser sensor, the rotary encoder, and the two-dimensional code band, and if the positioning device 14 includes a plurality of the laser sensor, the rotary encoder, and the two-dimensional code band, the crane 11 may be positioned by the plurality of positioning devices, and the positional information of the crane 11 may be determined by averaging.

In the embodiment of the application, the first positioning device is respectively arranged on the cart mechanism of the crane 11, the second positioning device is arranged on the cart mechanism of the crane 11, and the third positioning device is arranged on the lifting mechanism of the crane 11.

The third positioning device can comprise at least one of a laser sensor, a rotary encoder and a two-dimensional code belt and is used for positioning the lifting mechanism to obtain positioning signals of the lifting mechanism.
The positioning signals belong to electric signals, the first positioning device, the second positioning device and the third positioning device respectively send the positioning signals of the cart mechanism, the positioning signals of the trolley mechanism and the positioning signals of the lifting mechanism to the signal processing unit 21, and the signal processing unit 21 can realize the conversion of the electric signals, namely, the positioning signals of the cart mechanism, the positioning signals of the trolley mechanism and the positioning signals of the lifting mechanism are respectively subjected to signal conversion processing to obtain the position information of the cart mechanism, the position information of the trolley mechanism and the position information of the lifting mechanism, and send the position information of the cart mechanism, the position information of the trolley mechanism and the position information of the lifting mechanism to the control platform 12.
The control platform 12 controls the crane 11 to move based on the position information of the cart mechanism, the position information of the trolley mechanism, the position information of the lifting mechanism and the position information of the personnel.
In one possible implementation, the control platform 12 determines a candidate movement region of the person, that is, a region that the person may arrive within a certain time period in the future, based on the position information of the person and the person history position information. Then, the control platform 12 controls the crane 11 to bypass the candidate movement area based on the position information of the cart mechanism, the position information of the trolley mechanism and the position information of the lifting mechanism, that is, controls the crane 11 not to enter the candidate movement area in the process of planning and advancing the path in a certain period of time in the future, so as to ensure a certain distance from personnel in the area and prevent danger.
