[0003] For the safety of crawler crane construction, unrelated personnel and ground workers are prohibited from getting too close to the crawler crane when the crawler crane is in construction. However, most of the related technologies only monitor the status of the crawler crane and cannot issue an early warning when personnel get close to the crawler crane. Therefore, there are still safety hazards. Utility Model Content

DETAILED DESCRIPTION

[0051] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended Figure 1 -Attached Figure 4 , the technical solutions in the embodiments of the utility model are clearly and completely described.

Figure 1 As an implementation of the early warning system, the early warning system may include an infrared transmitter 101, an infrared receiver 102, an induction radar 103, a controller 104 and a voice announcer 105.

[0053] Among them, the infrared transmitter 101 and the infrared receiver 102 are arranged along the circumference of the crawler crane to form an early warning electronic fence area 118; when a person enters during the construction of the crawler crane, a first early warning signal is sent. The induction radar 103 is installed on the side and rear of the crawler crane to sense obstacles, and when an obstacle is sensed, a second early warning signal is sent. The controller 104 is installed in the control console in the crawler crane cab, and is used to receive and respond to the first early warning signal and send a first early warning message; it is also used to receive and respond to the second early warning signal and send a second early warning message. The voice announcer 105 is installed in the crawler crane cab to broadcast the first early warning message and the second early warning message. The first early warning message can be "someone has broken in", and the second early warning message can be "please stay away".

[0054] Furthermore, a ground settlement sensor 106 is installed on the crawler wheel of the crawler crane to collect ground settlement data. The controller 104 receives the ground settlement data and determines that when the ground settlement data exceeds the settlement safety range, a third warning message is sent; the voice announcer 105 announces the third warning message; the third warning message may be "ground settlement, suspend construction".

[0055] Reference Figure 2 As another embodiment of the early warning system, the early warning system may further include a face recognition device 107 and a lock-key assembly 200. The face recognition device 107 is installed in the cab and is used to collect and recognize the face image of the person entering the cab. If the face image matches the pre-stored operator face image, an unlock signal is sent. After the controller 104 receives and responds to the unlock signal, an action signal is sent. The lock-key assembly 200 is installed on the key cover 230 of the cab console and receives and responds to the action signal to open the keyhole.

[0056] In addition, an alcohol detector 108, a recorder 109, a driver behavior monitoring camera 110 and a display screen 111 are also installed in the cab. Among them, the alcohol detector 108 is installed in the cab to detect whether the operator has consumed alcohol and alarm when the alcohol value exceeds the standard. The recorder 109 is installed in the cab to collect audio information in the cab. The driver behavior monitoring camera 110 is installed in the cab to collect the operator's driving behavior image. The driving behavior image can be uploaded to the server background for behavior analysis to determine whether the operator is fatigued driving and whether there is irregular behavior such as playing with mobile phones. The display screen 111 is installed at the console to display early warning information.

[0057] Reference Figure 3 The lock and key assembly 200 may include a rotating cover plate 210 and a motor 220. The rotating cover plate 210 is rotatably connected to the key cover 230 via a rotating shaft; the motor 220 is installed inside the key cover 230, and the output shaft is coaxially fixedly connected to the rotating shaft. The motor 220 is in communication with the controller 104.

[0058] Reference Figure 4 As another implementation of the early warning system, the early warning system may also include a wind speed sensor 112 , a lateral pressure sensor 113 , an inclination sensor 114 , a rotation sensor 115 , a winch camera 116 and a thermal imaging dome camera 117 .

[0059] Among them, the wind speed sensor 112 is installed on the crane arm of the crawler crane to monitor the ambient wind speed and send the wind speed value. After receiving the wind speed value, the controller 104 makes a judgment. When the wind speed value is greater than the wind speed threshold, the controller 104 sends the fourth warning information, and the voice announcer 105 broadcasts the fourth warning information; the fourth warning information can be "the wind speed is too high, which is not conducive to construction". The lateral pressure sensor 113 is installed on the suspension rope of the crawler crane hook to obtain the load-bearing pressure of the hook and send the pressure value. After receiving the pressure value, the controller 104 makes a judgment. When the pressure value is greater than the pressure threshold, the controller 104 sends the fifth warning information, and the voice announcer 105 broadcasts the fifth warning information; the fifth warning information can be "beware of overweight". The inclination sensors 114 are respectively installed on the crawler crane's jib, boom and cab top, respectively obtain the jib inclination, boom inclination and horizontal inclination, and send the corresponding jib inclination, boom inclination and horizontal inclination values; the controller 104 receives the jib inclination, boom inclination and horizontal inclination values ​​and makes a judgment. If the jib inclination, boom inclination and horizontal inclination values ​​are not within the inclination threshold range, the sixth warning message is sent, and the voice announcer 105 broadcasts the sixth warning message; the sixth warning message can be "pay attention to tilt". The slewing sensor 115 is installed on the slewing gear ring of the crawler crane, and is used to obtain the slewing angle and speed, and send the slewing angle value and speed value; the controller 104 receives the slewing angle value and speed value and makes a judgment. If the slewing angle value is not within the slewing angle threshold range and the speed value is not within the speed threshold range, the seventh warning message is sent, and the voice announcer 105 broadcasts the seventh warning message; the seventh warning message can be "slewing is not in place". The winch camera 116 is installed at the winch of the crawler crane to collect working images at the winch. The thermal imaging dome camera 117 is installed on the main arm of the crawler crane to collect thermal images near the crawler crane. The display screen 111 displays working images and thermal images.

[0060] The controller 104 in the present application may be a single chip microcomputer; the warning information is divided into two warning levels, which can be distinguished by color on the display screen 111, for example, orange represents a low level and red represents a high level. When the voice announcer 105 announces the warning information, the warning level can be distinguished by the pitch, and the higher the warning level, the higher the pitch.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application in sequence. Any feature disclosed in this specification (including the abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
