Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, "connection" can mean a direct connection or an indirect connection through an intermediate medium, or it can mean the internal connection of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0021] Currently, safety protection measures used in the chemical and loading industries have certain limitations. Existing devices typically only activate when pipelines are subjected to significant external forces, failing to react promptly to early abnormalities such as slight vehicle movement. Furthermore, they cannot comprehensively and accurately monitor various anomalies during the loading process, and the protective measures lack a systematic approach, failing to achieve effective linkage between components, making it difficult to quickly implement effective countermeasures in the event of an accident. The loading and unloading protection system proposed in this application is designed to solve these problems.

[0022] like Figure 1 As shown, the loading and unloading protection system provided in this embodiment of the present invention includes: a loading subsystem 10 and an early warning subsystem 20, wherein the loading subsystem 10 and the early warning subsystem 20 are connected; the loading subsystem 10 includes a loading pump 101, an arm of arms 102 and a first control terminal (not shown in the figure), the loading pump 101 is located at the outlet of the vehicle's storage tank, the loading pump 101 is connected to the arm of arms 102 through an outlet pipe, the arm of arms 102 is located at the inlet of the main tank in the loading and unloading area, and the first control terminal is electrically connected to the loading pump 101.

[0023] The early warning subsystem 20 includes an electric control valve 201, a sensor, and a second control terminal (not shown in the figure). The second control terminal is electrically connected to the electric control valve 201, the sensor, and the first control terminal. The electric control valve 201 is installed on the outlet pipe between the loading pump 101 and the arm 102. The sensor is installed in the loading and unloading area to monitor the displacement information of vehicles in the loading and unloading area.

[0024] The loading subsystem 10 is connected to the early warning subsystem 20 for information exchange, so that when the loading subsystem 10 is started, the early warning subsystem 20 also enters the start state.

[0025] Specifically, both the first control terminal and the second control terminal can be PCs (Personal Computers) or mobile terminals such as laptops, tablets, or smartphones.

[0026] In one embodiment, the first control terminal may include a first display, and the second control terminal may include a second display. The first display is used to show the opening and closing status of the loading pump 101, and the second display is used to show the opening and closing status of the electric control valve 201 and displacement information.

[0027] Specifically, the electrically controlled valve 201 can be an electrically operated breakaway valve, which can quickly disconnect the connection when the outlet pipeline is subjected to a large external force such as unexpected tension, excessive tension, or impact. Of course, the electrically operated breakaway valve can also be opened or closed under the control of a second control terminal.

[0028] Specifically, when the loading subsystem 10 is started, the early warning subsystem 20 simultaneously enters normal working state. After the loading pump 101 is started, the early warning subsystem 20 begins to work in coordination, receiving real-time data from the sensors and performing analysis and judgment.

[0029] The electrically controlled valve 201 is in the open state during normal vehicle loading / unloading and when the vehicle is not being loaded / unloaded, and in the closed state during abnormal vehicle loading / unloading. Abnormal vehicle loading / unloading includes: when the vehicle is being loaded / unloaded, the second control terminal receives vehicle displacement information sent by a sensor, or the second control terminal receives information sent by a sensor indicating that personnel have entered the loading / unloading area.

[0030] This allows the sensors to detect abnormalities in advance, giving the system time to react, while the electric disconnect valve cuts off the pipeline at critical moments to prevent further leakage of liquid or gas, greatly improving the safety of the loading process and reducing the risk of accidents.

[0031] In a specific embodiment, such as Figure 1 As shown, the sensor may include a first sensor 202 and a second sensor 203. The first sensor 202 is positioned facing the front of the vehicle, and the second sensor 203 is positioned facing the rear of the vehicle. The first sensor 202 and the second sensor 203 are tilted relative to each other.

[0032] For example, the first sensor 202 and the second sensor 203 can be arranged diagonally opposite each other. The recognition area of ​​the first sensor 202 and the second sensor 203 fully covers the loading and unloading area. Personnel can move outside the loading and unloading area. When a person accidentally enters the loading and unloading area, the first sensor 202 or the second sensor 203 will identify the person's information and send it to the second control terminal.

[0033] Optionally, the sensor can be a lidar sensor. For example, both the first sensor 202 and the second sensor 203 are lidar sensors used to scan the displacement information of the front and rear of the vehicle and the abnormal entry of personnel.

[0034] It should be noted that the lidar sensor has the characteristics of high sensitivity and fast response, which can detect abnormalities in the early stages of an accident. Once abnormal signals such as personnel entering the cab or vehicle movement are detected, the control system can react quickly, stop the loading pump 101 and cut off the pipeline in a short time, effectively preventing the accident from escalating.

[0035] Of course, as other alternative embodiments, the sensor can also be a millimeter-wave radar, ultrasonic radar, radar-vision fusion sensor, etc.

[0036] In other embodiments, the sensor may include only one or three, four or more sensors, which is not limited in this application.

[0037] In one application scenario, two lidar sensors can be installed on the ground 1-1.5 meters away from the corner diagonally opposite each other before and after loading. These two sensors can monitor the loading site in real time. For example, ... Figure 1 As shown, a first sensor 201 is installed on the ground 1 meter away from the corner on the left front of the vehicle (or the upper left corner of the parking area), and a second sensor 202 is installed on the ground 1 meter away from the corner on the right rear of the vehicle (or the lower right corner of the parking area).

[0038] Sensors are used to detect subtle movements of personnel entering the cab and vehicles, collect real-time data on changes in the surrounding environment, and transmit the collected information to the control system promptly. Through the rational layout and installation of lidar sensors, the sensors can cover key areas of the loading site, ensuring comprehensive monitoring of abnormal situations. They can operate stably in complex environments, accurately detect anomalies, and reduce false alarms and missed alarms.

[0039] Furthermore, to better alert staff, the early warning subsystem 20 may also include an alarm electrically connected to the second control terminal, which is installed in the loading and unloading area. The alarm function provides clear warnings to on-site staff, facilitating timely response.

[0040] For example, the alarm can be installed at the boundary between the loading / unloading area and the external environment, or inside the loading / unloading area. The alarm can be an audible and visual alarm.

[0041] Furthermore, the first control terminal and / or the second control terminal may be connected to an external alarm device, which can provide audible and visual alarms, and the first and second displays are also used to display alarm information.

[0042] In one application scenario, if someone enters the cab from the outside or the vehicle moves within a preset distance (e.g., 30cm) during loading and unloading, the lidar sensor sends an abnormal signal to the second control terminal. The second control terminal then activates the alarm. If the person leaves within the preset alarm duration (e.g., 20 seconds), the alarm automatically cancels. If the person does not leave within the preset alarm duration, a shutdown signal for the loading pump 101 is sent to the first control terminal. The first control terminal then sends a shutdown control signal to the loading pump 101, causing it to stop operating.

[0043] This application fully considers the safety of individuals and vehicles. In the event of an accident, timely stopping of the loading pump 101 and breaking of the pipeline can prevent further damage to the vehicle due to liquid leakage and other accidents, thus protecting the interests of the staff.

[0044] Furthermore, to ensure that the pipeline is completely cut off, after the second control terminal sends a shutdown signal to the first control terminal for the loading pump 101, the second control terminal is also used to send a disconnect signal to the electric control valve 201 after a target time (such as 2 to 5 seconds) to make it perform an emergency pull-off action. At the same time, the horn sounds an alarm, and the loading system interface displays alarm information, so that the operators can understand the accident situation in a timely manner.

[0045] It should be noted that after the second control terminal sends a shutdown signal to the first control terminal for the loading pump 101, it controls the loading pump 101 to stop operating. This process lasts approximately 2 seconds. This 2-second delay is to avoid other problems caused by sudden pressure changes in the pipeline due to an instantaneous stop. After 2 seconds, a signal is sent to the electric control valve 201 to perform an emergency trip action.

[0046] As another optional embodiment, the early warning subsystem 20 may include an electrically operated breakaway valve in addition to the electrically controlled valve 201. The electrically operated breakaway valve is installed on the outlet pipeline between the loading pump 101 and the electrically controlled valve 201. The electrically controlled valve 201 may be an electrically operated ball valve, an electrically operated gate valve, an electrically operated stop valve, etc., and this application does not limit it.

[0047] By installing two valves, an electric disconnect valve and an electric control valve 201, on the outlet pipeline, the electric disconnect valve will automatically disconnect when the pipeline is subjected to abnormal impact or pulling. When the sensor detects abnormal vehicle movement or personnel entering the loading and unloading area, the electric control valve 201 will automatically disconnect. This can prevent the pipeline from failing to disconnect due to the abnormality of a single valve, achieving dual protection and improving safety.

[0048] Furthermore, such as Figure 1 As shown, in order to monitor the flow rate of the fluid in the outlet pipe in real time, the loading subsystem 10 may also include a pipe flow meter 103 electrically connected to the first control terminal. The pipe flow meter 103 is installed on the outlet pipe between the electric control valve 201 and the loading arm 102.

[0049] Furthermore, such as Figure 1 As shown, in order to achieve flexible control of the flow rate, the loading subsystem 10 may also include a pipeline flow switch 104 connected to the first control terminal. The pipeline flow switch 104 is set on the outlet pipeline between the pipeline flow meter 103 and the loading arm 102.

[0050] Furthermore, in order to more accurately detect slight vehicle displacement and personnel entry, the early warning subsystem 20 may also include a camera electrically connected to the second control terminal. The camera is set in the loading and unloading area to monitor vehicle displacement information and personnel information.

[0051] Optionally, the camera may include a single camera, two cameras, or more cameras. For example, the camera includes a first camera and a second camera, with the first camera facing the front of the vehicle and the second camera facing the rear of the vehicle. The first camera and the second camera are tilted relative to each other, and the first position detector, the second position detector, the first camera, and the second camera are each distributed at one of the four corners of the loading and unloading area.

[0052] It should be noted that in practical applications, after the protection system is installed, a comprehensive debugging of the entire system is required, including adjusting the sensitivity of the sensors and setting the parameters of the control system. This debugging ensures that the system can function properly and accurately respond to various abnormal situations.

[0053] During the integration process, existing systems need to be modified and upgraded to achieve seamless integration with this protection system. Through interface design and data transmission protocol development, it is ensured that the new system can effectively interact and collaborate with existing systems. This allows for full utilization of existing resources and reduces the enterprise's transformation costs.

[0054] This application employs a dual-system linkage control design involving a loading subsystem and an early warning subsystem to ensure both normal vehicle loading and unloading and environmental and personnel safety. The protection system maintains the electrically controlled valve in a normally open state during normal loading / unloading and when not loading / unloading. This design aims to ensure the smooth progress of the loading process and prevent erroneous closure of the electrically controlled valve from affecting loading efficiency. Upon receiving an abnormal signal from the sensor, the system controls the electrically controlled valve to perform an emergency shut-off action. Therefore, under normal circumstances, the system continuously monitors and maintains the electrically controlled valve in a normally open state; when an abnormal signal is received from the sensor, the system reacts quickly and controls the electrically controlled valve to perform an emergency shut-off action.

[0055] The early warning subsystem includes sensors for real-time monitoring of the loading site, accurately detecting even the slightest movements of personnel entering the cab and vehicles, and transmitting the collected information to the loading subsystem. This protective system can not only disconnect the pipeline when subjected to significant external force, but also react promptly to early abnormalities such as slight vehicle movement.

[0056] This application can be applied in chemical enterprises, logistics companies, and other related fields, meeting the market demand for efficient and reliable loading protection systems. On the one hand, adopting this protection system can reduce the occurrence of accidents and lower economic losses caused by liquid leaks, equipment damage, etc.; on the other hand, it improves loading efficiency.

[0057] In summary, the loading and unloading protection system provided in this embodiment adopts a dual-system linkage control design of the loading subsystem and the early warning subsystem. Sensors are installed on the loading ground to detect slight movements of personnel and vehicles entering the loading and unloading area. In the event of an abnormality, the system can promptly stop the loading pump and disconnect the pipeline, effectively preventing large-scale leakage of loading liquids and ensuring the safety of the loading site and personnel. This system has advantages such as early warning, rapid response, high reliability, and user-friendly design, and can effectively prevent large-scale leakage of loading liquids.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0059] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
