Description

Technical Field

[0001] This invention relates to the field of safety protection technology, and in particular to a safety protection system, method and storage medium for a concrete mixing host. Background Technology

[0002] In related technologies, the safety protection of the mixing host during maintenance in a mixing plant is mainly achieved through the following three conventional means: (1) emergency stop switch for the mixing host; (2) inspection port closure detection sensor; (3) power outage of the main circuit of the power cabinet and other process management. The conventional process in related technologies is as follows: the maintenance plan is issued, the emergency stop switch is pressed on the remote control terminal, and when maintenance begins, the maintenance personnel disconnect the power cabinet, press the emergency stop switch for the mixing host at the same time, open the maintenance door and enter the mixing host for maintenance. After the maintenance is completed, the maintenance personnel close the maintenance door, the power cabinet is switched on, the emergency stop switch for the mixing host is reset, the emergency stop on the remote control terminal is reset, and the control system starts the mixing host and powers it on.

[0003] This process in the relevant technology involves proactive safety protection for personnel and passive safety protection for equipment. Its reliability depends on the implementation of the mixing plant's safety management system, the competence of personnel, and the quality of the equipment. Significant safety vulnerabilities can arise when maintenance personnel lack safety awareness, safety management is inadequate, or equipment sensors are old and in disrepair. For example: accidental closure of the control panel during maintenance; malfunction of the inspection port closure detection sensor; aging of the hydraulic struts of the inspection door, causing the inspection door to fall unexpectedly; and forgetting to press the emergency stop switch or its malfunction.

[0004] Safety accidents during the maintenance of concrete mixing units can easily lead to serious accidents such as personal injury and death. There is an urgent need in this field for new solutions that can proactively improve the safety protection of concrete mixing units in batching plants. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0042] The following is combined with Figures 1 to 11 The present invention describes a safety protection system, method, and storage medium for a concrete mixing host.

[0043] 1. For example Figure 1 As shown, an embodiment of the present invention provides a safety protection system 100 for a concrete mixing host, which may include:

[0044] Monitoring device 101 is used to monitor the inspection port of the concrete mixing host.

[0045] Server 102 is connected to the monitoring device. The server is equipped with a trained target detection model. The server is used to: determine whether the concrete mixing host is in an abnormal state based on the monitoring video transmitted by the monitoring device, and issue a host abnormal signal based on the abnormal state; the host abnormal signal indicates that the concrete mixing host is in an abnormal state.

[0046] The control device, connected to the server, is used to receive abnormal signals from the host and issue a start-prohibition signal based on the abnormal signals. The start-prohibition signal is used to prevent the concrete mixer from starting.

[0047] Specifically, the prohibition start signal is used to prohibit the concrete mixing host from being started for production by the control device under any circumstances.

[0048] Specifically, a monitoring device is installed at an appropriate location on the mixing host of the batching plant. The monitoring device may include at least one camera, which can collect monitoring video at the inspection port of the concrete mixing host 24 hours a day.

[0049] Specifically, the object detection model can also be called an object detection algorithm. In this embodiment, the object detection model can be YOLOv5 (You Only Look Once version 5). YOLO v5 is the fifth version of the YOLO object detection model series. Furthermore, YOLO v5 has five different precision versions: s, m, l, x, and n. This embodiment of the invention does not impose any restrictions on the specific version of YOLO v5 used for object detection. YOLO v5 has 24 layers, including an input, a backbone network, a neck network, and a prediction network (Head). The structure of the object detection model based on YOLO v5 can be as follows: Input → Backbone Network → Neck Network → Prediction Network → Output. The Backbone is mainly used for feature extraction, the Head is mainly used to predict the type and location of the target (in this embodiment, the target is a pedestrian), and the Neck is located between the Backbone and the Head, which can be used to extract more complex features.

[0050] Specifically, the server and control device can communicate via Ethernet.

[0051] In related technologies, the safety protection process for concrete mixing plants involves both proactive personnel safety protection and passive equipment protection. Reliability depends on the implementation of the mixing plant's safety management system, the competence of personnel, and the quality of the equipment. Significant safety vulnerabilities exist when maintenance personnel lack safety awareness, safety management is inadequate, or equipment sensors are old and in disrepair. For example: accidental activation of the switch during maintenance; malfunction of the inspection port closure detection sensor; aging of the hydraulic struts of the inspection door, causing the door to fall unexpectedly; and forgetting to press the emergency stop switch or its malfunction. Safety accidents during mixing plant maintenance can easily lead to serious accidents such as personal injury or death.

[0052] In this embodiment, the monitoring video at the maintenance port of the concrete mixer is transmitted to the server via a monitoring device. The server uses a trained target detection model to determine whether the mixer is in an abnormal state. If it is in an abnormal state, an abnormal signal is sent to the control device, which then prevents the concrete mixer from starting. Thus, the solution in this embodiment can detect different states of the maintenance port of the concrete mixer through a target detection algorithm. When the maintenance port is under maintenance, the mixer is prohibited from starting, which can ensure the personal safety of maintenance personnel and avoid human error or accidents. This provides proactive, 24-hour safety protection for the concrete mixer. Based on the traditional safety protection process for concrete mixers, this method improves the safety protection of the concrete mixer and, consequently, the safety protection of the concrete batching plant.

[0053] In an exemplary embodiment, the server may be specifically used to: determine whether the maintenance door of the inspection port is open based on the monitoring video transmitted by the received monitoring device and using a trained target detection model; if the maintenance door is open, determine that the mixing host is in an abnormal state.

[0054] In this embodiment, the question of whether the concrete mixing host is in an abnormal state is explained in detail, for example... Figure 2 As shown, the inspection door of the access panel is open, which indicates that the concrete mixer is in an abnormal state. Accordingly, the target detection model YOLOv5 can analyze the video frames in the monitoring video to determine that the inspection door of the access panel is open. Thus, the server can use the output of the target detection model to conclude that the concrete mixer is in an abnormal state, and then output a host abnormality signal to the control device to prevent the concrete mixer from starting. This ensures the personal safety of maintenance personnel who are repairing the mixer in an abnormal state, improves the safety protection of the concrete mixer, and enhances the safety protection of the concrete batching plant.

[0055] Furthermore, in an exemplary embodiment, the server can also be specifically used to: determine whether the fastening bolts of the inspection port are in a locked state based on the monitoring video transmitted by the received monitoring device, using a trained target detection model; if the fastening bolts are not in a locked state, determine that the mixing host is in an abnormal state.

[0056] Specifically, the fastening bolts of the access panel are used to lock the access door of the access panel, such as... Figure 3 , Figure 4 and Figure 5 As shown, the bolts securing the inspection port are not tightened. This can indicate that the mixing plant is in an abnormal state, or that maintenance personnel are performing maintenance on the concrete mixing unit. Figure 10 , Figure 7 and Figure 8 As shown, the fastening bolts of the inspection port are in the locked state, which indicates that no maintenance personnel are performing maintenance on the concrete mixing unit. In other words, it indicates that the mixing unit is in normal condition and can be started for production.

[0057] In practice, the maintenance door at the access point may automatically close due to aging of related structures such as the hydraulic struts. This could potentially trigger the start of the concrete mixer by activating the conventional access point closure detection sensor, causing injury to maintenance personnel. To avoid this, the YOLOv5 target detection model in this embodiment analyzes video frames from the monitoring video to determine if the bolts securing the access door are not tightened. The server can then use the output of the target detection model to conclude that the concrete mixer is in an abnormal state. It can then send a host abnormality signal to the control device via Ethernet at a fixed frequency (e.g., a preset frequency of 0.5 seconds, but not limited to a preset value) to prevent the concrete mixer from starting. This significantly improves the safety of maintenance personnel in abnormal states and enhances the safety protection of the concrete mixer and the entire concrete mixing plant.

[0058] In an exemplary embodiment, the server may also be specifically used to: determine whether there is a maintenance sign near the maintenance port based on the monitoring video transmitted by the monitoring device, and if there is a maintenance sign, determine that the mixing host is in an abnormal state.

[0059] For example, a maintenance sign can be a maintenance tag.

[0060] In practice, maintenance personnel may sometimes temporarily leave the maintenance opening while performing maintenance, such as to retrieve other maintenance tools. In such cases, if the maintenance door is accidentally closed, or if other obstacles block the location of the fastening bolts, the target detection model may not be able to detect that the concrete mixer is in an abnormal state, which may trigger the start of the mixer and cause a dangerous situation. Therefore, in this embodiment, when maintenance personnel are inspecting the mixer, they can place a maintenance sign near the maintenance opening. This can avoid the dangerous situation of the maintenance door being accidentally closed and other obstacles blocking the location of the fastening bolts, thus greatly improving the safety protection of the concrete mixer and the concrete batching plant.

[0061] In an exemplary embodiment, the safety protection system for the concrete mixing host may further include: an alarm device connected to the control device, used to issue an alarm signal based on an abnormal signal from the host.

[0062] Specifically, the alarm device may include an alarm light, and may also include an LED maintenance sign.

[0063] In some embodiments, when the server detects that the access port is in an abnormal state, it can send a relevant signal to the camera via Ethernet. The camera's data switch signal will activate the mixer alarm light and LED maintenance sign to warn that the mixer is under maintenance.

[0064] In other embodiments, a network relay can be used to activate the mixer alarm light and LED maintenance sign to indicate that the mixer is under maintenance.

[0065] In this embodiment, by setting up an alarm device, the safety protection of the concrete mixing host and the concrete mixing plant can be greatly improved.

[0066] In an exemplary embodiment, the control device includes a host computer control device, which is used to receive a host abnormality signal and issue a start prohibition signal based on the host abnormality signal.

[0067] In an exemplary embodiment, the control device further includes a lower-level control device, which is used to receive a prohibition signal and control the concrete mixing host not to start based on the prohibition signal.

[0068] In an exemplary embodiment, the process of training the object detection model may include: training an initial object detection model using a data sample set. The process of acquiring the data sample set may include: acquiring monitoring video frames of the access port, and marking the opening of the access port's maintenance door (e.g., ...). Figure 2 As shown), the fastening bolts are not tightened (e.g. Figures 3 to 5 As shown), tighten the fastening bolts (as shown). Figures 10 to 8 (As shown) and other target detection samples.

[0069] In a specific embodiment, such as Figure 9 As shown, the concrete mixing host safety protection system 100 may include: a monitoring device 101, a server 1021 with pre-trained YOLOv5 deployed, a host computer 1031, a SYMC slave computer 1032, and an alarm light 104.

[0070] If server 1021 detects that the access door is open using the YOLOv5 model, it immediately sends a first host abnormality signal to host computer 1031 via Ethernet at a fixed frequency, such as 0.5 seconds.

[0071] During normal production, the access port fastening bolts must be in the locked state, because if they are not locked, dust will come out of the access port. When the maintenance personnel are performing maintenance, if the access door is accidentally closed due to the aging of the hydraulic strut, the regular access port closure detection sensor will be activated. However, the fastening bolts cannot be automatically locked. Therefore, when the server 1021 detects that the access port fixing bolts are not locked through the YOLOv5 model, it immediately sends a second host abnormal signal to the host computer 1031 via Ethernet at a fixed frequency, such as 0.5 seconds.

[0072] After receiving the first host abnormality signal or the second host abnormality signal, the host computer 1031 sends a prohibition start signal to the slave computer 1032. After receiving the prohibition start signal, the slave computer 1032 controls the mixing host not to start.

[0073] When the YOLOv5 model detects that the maintenance port is in an abnormal state, the server 1021 can send an alarm signal to the camera via Ethernet. The camera's data switch signal can then activate the mixer alarm light, or the network relay can activate the mixer alarm light and maintenance sign to warn that the mixer is under maintenance.

[0074] When the YOLOv5 model detects that the fastening bolts are tightened, the server 1021 sends a system status normal signal to the host computer 1031 via Ethernet. If the host computer 1031 does not receive the status normal signal, it will issue an alarm prompt: actively check the protection system of the concrete mixer to prevent the protection system of the concrete mixer from failing.

[0075] In addition, regarding the push of maintenance videos: the host computer 1031 can receive video streams after algorithm processing, allowing operators to grasp abnormal states in real time and avoid the inability to understand the on-site status due to insufficient monitoring positions on the remote control screen.

[0076] This invention provides proactive safety protection for mixer maintenance based on system decisions, eliminating subjective human factors and preventing safety loopholes and accidents. The concrete mixer's protection system performs self-checks by detecting bolt tightness and continuously sending normal heartbeat signals, preventing system failures from going unnoticed.

[0084] If the inspection door is open, it indicates that the mixing unit is in an abnormal state.

[0086] Based on the monitoring video, the trained target detection model is used to determine whether the fastening bolts of the inspection port are in the locked state.

[0087] If the fastening bolts are not in the locked position, it indicates that the mixing unit is in an abnormal state.

[0088] In an exemplary embodiment, step 1020, determining whether the concrete mixing host is in an abnormal state based on the monitoring video and using a trained target detection model, may further include:

[0089] Based on the monitoring video transmitted by the monitoring device, the trained target detection model is used to determine whether there are maintenance signs near the maintenance port. If maintenance signs are found, it is determined that the mixing host is in an abnormal state.
