Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly described below with reference to the drawings in the embodiments of the present utility model.
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.
Referring to fig. 1-2, a preferred embodiment of the utility model provides a tower crane laser detection engineering installation warning device, which comprises a luffing trolley 2, a warning device, a display screen and a micro controller.
In the embodiment, the luffing trolley 2 is a trolley capable of moving along the arm support of the tower crane, and the luffing trolley 2 is provided with a hook for hoisting articles.
In this embodiment, the warning device comprises a laser emitter 301 for projecting the position of the hook on the ground, a thermal infrared sensor 302 for detecting whether a person is under the hook, and a brightness sensor 303 for detecting the intensity of ambient light. The laser emitter 301 and the thermal infrared sensor 302 are arranged below the luffing trolley 2, parallel to the hook, and the brightness sensor 303 is arranged on the side surface of the luffing trolley 2.
In this embodiment, the laser mark of the laser emitter 301 is circular, so that the projection area of the hook on the ground can be clearly displayed, and the attention of the personnel below can be reminded. The luminous intensity of the laser emitter 301 can be automatically adjusted according to the intensity of the ambient light detected by the brightness sensor 303, so as to ensure the clear visibility of the laser mark on the ground. When the intensity of the ambient light is higher than a preset threshold, the brightness sensor 303 sends a signal to the micro controller to increase the luminous intensity of the laser emitter 301; when the intensity of the ambient light is below a preset threshold, the brightness sensor 303 sends a signal to the microcontroller to decrease the intensity of the light emitted by the laser emitter 301.
In this embodiment, the thermal infrared sensor 302 is a dual-element thermal infrared sensor, which has high sensitivity and high signal-to-noise ratio, and can effectively distinguish the human body and other objects below the hook, and send the detection result to the micro controller. When the thermal infrared sensor 302 detects that a person enters a dangerous area, the micro controller sends out warning information to an operator through a display screen, and a flashing laser mark is projected to the ground through the laser emitter 301 so as to remind the person to leave rapidly.
In this embodiment, the display screen is disposed in the operation room of the tower crane, and is used for displaying information such as whether a person is under the current hook and the working state of the laser transmitter 301, so that an operator can know and process the situation in time.
In this embodiment, the micro controller is electrically connected with the laser emitter 301, the thermal infrared sensor 302, the brightness sensor 303, and the display screen, and is configured to receive and process various signals, and regulate and control the operation of the warning device.
When the utility model is specifically used, the laser emitter 301 will project a circular laser mark on the ground, which represents the projection area of the hook on the ground. Meanwhile, the thermal infrared sensor 302 continuously detects whether a person is under the hook, and transmits the detection result to the micro controller. If the thermal infrared sensor 302 detects that a person enters a dangerous area, the micro controller sends out warning information to an operator through a display screen, and a flashing laser mark is projected to the ground through the laser emitter 301 so as to remind the person to leave quickly.
When the utility model is specifically used, the brightness sensor 303 automatically adjusts the luminous intensity of the laser emitter 301 according to the ambient light intensity, so as to ensure the clear visibility of the laser mark on the ground. An operator can check whether a person exists below the current hook, the working state of the laser transmitter 301 and other information through the display screen, so that the operator can know and process the situation in time conveniently.
In this embodiment, the processor is stm32 or other micro controllers with similar functions, which can be implemented in the prior art, and are applicable to the present utility model, and detailed descriptions thereof are omitted herein.
In this embodiment, the control circuit of the present utility model is a common technology in the circuit field, and can be implemented by a person skilled in the art, and will not be described herein.
