[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] The remote control emergency stop protection device of existing engineering machinery usually adopts a one-control-multiple mode, that is, when a certain engineering machinery fails or an emergency occurs and an emergency stop is required, the operator presses the emergency stop button on the remote control, and all engineering machinery on the site will trigger the emergency stop protection. Although this method can protect engineering machinery that has an accident, machinery that is not faulty will also be affected and stop working. If you want to continue working, you need to manually release the emergency stop protection, which greatly affects work efficiency.

[0035] In order to solve the above problems, the present invention proposes a directional emergency stop device, which aims to solve the problem that the existing emergency stop remote control device cannot achieve emergency stop for a single engineering machinery, thereby reducing work efficiency.

[0036] like Figures 1 to 3 In one embodiment, the directional emergency stop device includes a remote control device 10, a plurality of recognition images 20 and a plurality of receiving control components 30. The remote control device 10 includes a housing and a recognition module and a directional transmission module 11 arranged inside the housing. The housing is provided with a first start key 12 at positions corresponding to the recognition module and the directional transmission module 11. Each recognition image 20 is used to be respectively arranged on each engineering machine, and a receiving control component 30 is used to be correspondingly installed on an engineering machine. The receiving control component 30 includes an electrically connected receiving parsing module and an emergency stop control module.

[0037] The recognition module collects and processes the recognition image 20, and controls the directional transmission module 11 to transmit a directional emergency stop signal to multiple engineering machines, the directional emergency stop signal includes control information and recognition information; a receiving and parsing module of an engineering machine recognizes and parses the recognition information to match it with its own information, and the emergency stop control module of the engineering machine receives the control information and controls the engineering machine to stop urgently.

[0038] In this embodiment, the remote control device 10 is a remote controller, and the housing of the remote controller adopts a dustproof and waterproof design to adapt to harsh working environments, thereby increasing the service life of the remote control device 10. The remote control device 10 includes a recognition module and a directional transmission module 11. The recognition module is started and stopped by a first start key 12. The recognition module is used to collect and process the recognition image 20 set by the corresponding identification module on the engineering machinery. During the recognition process, the recognition module will first pre-process the recognition image 20, such as contrast enhancement, brightness adjustment, sharpening, etc., to ensure that the key information of the recognition image 20 is clear and discernible. After pre-processing, the recognition module will extract features of the recognition image 20 according to the shape, color, texture or other image attributes of the recognition image 20, and then generate corresponding recognition information. The directional transmission module 11 will transmit a directional emergency stop signal to the engineering machinery based on the identification information generated by the identification module. The directional emergency stop signal includes control information and identification information. A receiving control component 30 is provided on the engineering machinery. After the receiving control component 30 receives the directional emergency stop signal, its receiving and parsing module determines whether the identification information in the directional emergency stop signal matches the mechanical information of the engineering machinery. If the match is successful, the emergency stop control module of the receiving control component 30 receives the control information of the directional emergency stop signal to perform an emergency stop on the engineering machinery, thereby realizing a directional emergency stop and greatly improving the emergency stop efficiency of the engineering machinery.

[0039] The present invention proposes a directional emergency stop device, including a remote control device 10 and a plurality of receiving control components 30. The remote control device 10 includes a shell and an identification module and a directional transmission module 11 arranged inside the shell. A first start button 12 is arranged on the shell corresponding to the identification module and the directional transmission module 11. An identification image 20 is arranged on the engineering machinery corresponding to the identification module. The plurality of receiving control components 30 are installed on a plurality of engineering machinery. One receiving control component 30 corresponds to one engineering machinery. A receiving analysis module and an emergency stop control module are arranged in the receiving control component 30. When a certain construction machinery needs to be directional-stopped, the operator presses the first start button 12 to start the recognition module to collect and process the content of the recognition image 20. The directional transmission module 11 transmits a directional emergency stop signal, which includes control information and identification information. When the receiving control component 30 receives the directional emergency stop signal transmitted by the directional transmission module 11, its receiving and parsing module first parses and determines the identification information in the directional emergency stop signal. When the parsing module determines that the identification information matches the information of the construction machinery itself, the emergency stop control module receives the control information of the directional emergency stop signal to control the construction machinery to perform an emergency stop, thereby achieving an emergency stop of a single construction machinery, thereby improving the emergency stop efficiency.

[0040] like Figures 1 to 3 In one embodiment, the recognition module includes a processing module 13 and a camera 14, the first start button 12 is electrically connected to the recognition module, the recognition module is arranged inside the shell, the camera 14 is arranged on a surface of the shell, the camera 14 is electrically connected to the processing module 13, and the processing module 13 is electrically connected to the directional transmission module 11.

[0041] In this embodiment, the first start button 12 is directly electrically connected to the recognition module. When the operator needs to start the recognition process, he can press the first start button 12. This design simplifies the operation process and thus improves the emergency response speed. The camera 14 is embedded in a surface of the shell to ensure that the installation is stable and the recognition image 20 on the engineering machinery can be clearly and completely captured. The processing module 13 can be a high-performance microprocessor responsible for executing complex image processing algorithms. It performs real-time analysis on the image captured by the camera 14 to identify the recognition image 20 on the engineering machinery. The camera 14 is connected to the processing module 13 by an electrical connection, which ensures the high-speed transmission and instant processing of the recognition image 20 data, reduces signal delay, and thus improves the overall response speed of the system. The processing module 13 is electrically connected to the directional transmission module 11. When the processing module 13 completes the recognition and processing of the recognition image 20, the directional transmission module 11 can immediately send a directional emergency stop signal to ensure the stability and timeliness of signal transmission. The provision of the identification module in this embodiment improves the convenience of operation and enhances the functionality and response speed of the directional emergency stop device, so that the emergency stop of the construction machinery can be quickly and accurately controlled in an emergency, thereby ensuring the safety of the work site.

[0042] In other embodiments, a dust cover may be provided outside the camera 14 to ensure the camera's own shooting clarity.

[0043] like Figure 3 In one embodiment, the identification image 20 is a one-dimensional code or a two-dimensional code.

[0044] In this embodiment, the identification image 20 can be selected as a one-dimensional code or a two-dimensional code, so that the identification image 20 can store a large amount of information in a small area, and has good fault tolerance. Even if part of the image is damaged to a certain extent, the recognition module can still successfully recognize it, thereby improving the practicality of the identification image 20. In addition, the one-dimensional code and the two-dimensional code are simple to make and low in price, which greatly reduces the production cost of the identification image 20.

[0045] like Figure 3 In one embodiment, a plurality of identification images 20 are provided, and the plurality of identification images 20 are used to be provided on different surfaces of each engineering machine.

[0046] In this embodiment, identification images 20 are provided on different surfaces of a construction machinery so that the camera 14 can scan and identify from different perspectives, while achieving full coverage of the identification image 20. Even in a complex working environment, it can be ensured that at least one identification image 20 is within the shooting range of the camera 14, thereby simplifying the operating process and improving the emergency stop efficiency.

[0047] like Figures 1 to 3 In one embodiment, the remote control device 10 also includes a laser emitter 15, and the shell is provided with a second start button 16 corresponding to the laser emitter 15, the laser emitter 15 is electrically connected to the second start button 16, the laser emitter 15 and the camera 14 are arranged on the same surface of the shell, and the laser spot emitted by the laser emitter 15 is irradiated on the recognition image 20, so that the camera 14 is facing the recognition image 20.

[0048] In this embodiment, the remote control device 10 further includes a laser emitter 15, which assists the camera 14 to accurately align the recognition image 20 by emitting a laser spot. The laser emitter 15 and the camera 14 are arranged on the same surface of the housing to ensure that the laser spot and the field of view of the camera 14 can be accurately aligned. Through the guidance of the laser spot, the camera 14 can more accurately face the recognition image 20, thereby improving the accuracy and speed of image recognition. The emergency stop efficiency of the directional emergency stop device is further improved.

[0049] like Figures 1 to 3In one embodiment, the remote control device 10 further includes a prompt component 17, which is electrically connected to the processing module 13, and is disposed on the surface of the shell, and is used to respond to the analysis result of the recognition module on the recognition image 20.

[0050] In this embodiment, the prompt component 17 can be a buzzer or an LED prompt screen. After the processing module 13 completes the analysis of the recognition image 20, it will pass the result to the prompt component 17. The prompt component 17 sends a corresponding prompt signal according to the analysis result of the processing module 13, such as the sound of a buzzer or the display information on the LED prompt screen, so that the operator can quickly understand whether the recognition module successfully analyzes the recognition image 20, so as to take further measures. The prompt component 17 in this embodiment provides an intuitive operation feedback mechanism for the operator, thereby improving the ease of use of the directional emergency stop device and enhancing the safety and reliability during the operation.

[0051] like Figures 1 to 3 In one embodiment, the remote control device 10 further includes a general emergency stop module 18, which is disposed inside the housing, and a third start button 19 is disposed on the housing corresponding to the general emergency stop module 18;

[0052] The general emergency stop module 18 can transmit a general emergency stop signal, and the receiving control components 30 of multiple engineering machines can all receive the general emergency stop signal to control all engineering machines to perform an emergency stop.

[0053] In this embodiment, in order to further cope with more urgent working situations, the directional emergency stop device also includes a general emergency stop module 18. The general emergency stop signal emitted by the general emergency stop module 18 can be received and processed by the receiving control component 30 of all engineering machinery without the need for analysis and judgment, thereby greatly shortening the response time. All engineering machinery that receive the general emergency stop signal will immediately perform an emergency stop operation to ensure the safety of the on-site engineering machinery. The setting of the general emergency stop module 18 in this embodiment provides additional safety protection for engineering machinery, improves the efficiency of emergency handling, and thus improves the practicality of the directional emergency stop device.

[0054] like Figure 4 The present invention also proposes a control method based on the directional emergency stop device, comprising the following steps:

[0055] Step S100: controlling the recognition module to collect and analyze the recognition image 20 of the engineering machinery to be stopped urgently;

[0056] Step S200: controlling the directional emergency stop module to transmit a directional emergency stop signal according to the recognition result of the recognition module;

[0057] Step S300: the identification module of the receiving control component 30 parses the identification information of the directional emergency stop signal to determine whether the identification information matches the information of the engineering machinery itself. If so, the emergency stop control module of the receiving control component 30 controls the engineering machinery to be stopped to perform an emergency stop.

[0058] In a specific embodiment, when it is necessary to urgently stop a certain construction machinery, firstly, the camera 14 of the recognition module is aimed at the recognition image 20 on the construction machinery to be urgently stopped, the camera 14 collects the recognition image 20 on the surface of the construction machinery, and the processing module 13 analyzes it at the same time, so as to determine the identity information of the construction machinery to be urgently stopped. After the recognition module successfully analyzes the recognition image 20 and confirms the identity of the construction machinery, the processing module 13 will feed back the result to the directional transmission module 11. The directional transmission module 11 transmits a specific directional emergency stop signal according to the feedback result of the processing module 13. The signal includes information for controlling the emergency stop operation and identification information that can only be analyzed and processed by the construction machinery to be urgently stopped. The receiving control component 30 of the construction machinery to be urgently stopped receives the signal. After the directional emergency stop signal is received, the receiving and parsing module in the receiving control component 30 begins to parse the identification information in the directional emergency stop signal. This information may include the unique identification code of the engineering machinery, operating instructions and other verification data. The receiving and parsing module compares the parsed identification information with the information stored in the engineering machinery itself. If the identification information matches the engineering machinery's own information, the receiving and parsing module transmits the directional emergency stop signal to the emergency stop control module. The emergency stop control module performs an emergency stop operation based on the received directional emergency stop signal to quickly stop all movements and operations of the engineering machinery. If the identification information does not match, the receiving control component 30 will ignore the signal and will not perform the emergency stop operation to prevent misoperation, thereby achieving precise emergency stop control of the engineering machinery.

[0059] like Figure 4 , before the step S100 of controlling the recognition module to collect and analyze the recognition image 20 of the engineering machinery to be stopped urgently, the following steps are also included:

[0060] Step S100A: controlling the laser emitter 15 to emit a laser beam so that the laser beam is irradiated onto the recognition image 20 on the construction machine.

[0061] In a specific embodiment, before the operator prepares to collect and analyze the identification image 20 of the engineering machinery to be stopped urgently, the operator first activates the laser emitter 15 on the remote control device 10 so that the laser emitter 15 emits a laser beam. The laser beam provides a visual indicator line to help the operator more accurately locate the relative position between the camera 14 and the identification image 20, greatly improving the operator's capture speed and success rate of the identification image 20.

[0062] The present invention also proposes a directional emergency stop system (not shown), which includes a directional emergency stop device and multiple engineering machines. The directional emergency stop device controls at least one of the multiple engineering machines to perform a directional emergency stop. Since the directional emergency stop system adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0063] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
