Description

Technical Field

[0001] The present invention belongs to the field of industrial control technology, and in particular relates to a detection system and method for an unmanned new energy battery swap station. Background Art

[0002] Under the background of the rapid development of the current new energy battery swap industry, battery swap stations, as the key node for ensuring the endurance of electric vehicles, are becoming the focus of the industry. Battery swap stations not only shoulder the important mission of efficiently and safely supplying electricity to electric vehicles, but also keep up with the rapid pace of technological development, gradually transforming from the traditional manned management mode to a more intelligent and efficient unmanned mode. This transformation not only represents technological innovation, but also a positive response to the vision of future smart transportation and smart cities.

[0003] However, the road to unmanned battery swap stations is not a smooth one. Two core issues hinder the smooth progress of this process. The first is the success rate of battery swapping, which is directly related to the user experience and the operational efficiency of the battery swap station. In an unmanned environment, how to ensure that every battery swap operation can be completed accurately. Second, the auxiliary identification of vehicle entry and the intrusion and interference of people or objects cannot be ignored. In an unmanned battery swap station, how to efficiently and accurately identify and guide vehicles into the battery swap area, while effectively preventing the intrusion of unauthorized people or objects, to ensure the safe operation of the battery swap station.

[0004] In view of the above problems, there is an urgent need for a detection system and method designed specifically for unmanned new energy battery swap stations. Summary of the invention

[0005] The main technical problem solved by the present invention is to provide a detection system and method for an unmanned new energy battery swap station, which significantly improves the operating efficiency and safety of the battery swap station. The system can not only effectively identify vehicle information and monitor vehicle location, but also detect and prevent intrusion in real time to ensure the safety of the battery swap process.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is:

[0007] A detection system for an unattended new energy battery swap station, comprising:

[0008] A battery swap station body, the battery swap station body comprising an entrance and an exit;

[0009] A license plate recognition camera is provided at the entrance of the main body of the battery swap station and is used to recognize the license plate information of the vehicle entering;

[0010] A radar, arranged at the top of the interior of the battery swap station body, for detecting whether a vehicle is located inside the battery swap station;

[0011] Intrusion detection gratings, one each provided at the entrance and exit of the power swap station, for detecting whether there are intruders or objects in the protection area;

[0012] An intrusion detection camera is installed at the internal entrance of the battery swap station to monitor the dynamic situation of vehicles and personnel in the battery swap station;

[0013] A V-groove photoelectric wheel detection sensor is arranged on the inner floor of the battery swap station and is used to detect whether the vehicle wheels are parked at a designated position;

[0014] The host computer receives and analyzes the detection signals sent by the license plate recognition camera, the radar, the intrusion detection grating, the intrusion detection camera and the V-groove photoelectric wheel detection sensor, and sends control instructions to the execution end; the execution end includes a gate and a voice broadcast box;

[0015] A gate, arranged at the entrance of the main body of the battery swap station, receives and executes control instructions sent by the host computer;

[0016] The voice broadcast box is arranged inside the main body of the battery swap station and receives and executes the voice broadcast instructions sent by the host computer.

[0017] Furthermore, the detection system also includes a cloud platform, which is communicatively connected to the host computer and receives data sent by the host computer.

[0018] Furthermore, two intrusion detection cameras are provided, and the two intrusion detection cameras are respectively arranged at the right rear and the left rear of the battery swap station.

[0019] Furthermore, two V-groove photoelectric wheel detection sensors are provided, and the two intrusion detection cameras detect the left front wheel and the right front wheel of the vehicle respectively.

[0020] A vehicle entry judgment method using a detection system of an unattended new energy battery swap station includes the following steps: when a vehicle arrives at the battery swap station, a license plate recognition camera recognizes the vehicle license plate information and uploads the acquired data to a host computer, the host computer searches the license plate to confirm whether the vehicle is eligible for battery swapping, if the search result shows that the vehicle is not in the battery swapping qualification list, a voice broadcast prompts "vehicle information error", if the search result shows that the vehicle is a valid battery swapping vehicle, the system sends a command to lift the gate, and voice broadcasts prompts the driver to drive the vehicle into the battery swap station;

[0021] After the vehicle enters the battery swap station, the radar located on the top of the station detects whether there is a vehicle. If the radar does not detect the vehicle, a voice announcement will be made that “the vehicle has not reached the designated area”. If the radar detects the vehicle, a V-groove photoelectric sensor will be used to verify whether the vehicle is parked in the designated position. If the V-groove photoelectric sensor determines that the vehicle is not parked in place, a voice announcement will be made that “the vehicle has not reached the designated area”. If the V-groove photoelectric sensor determines that the vehicle is parked in place, a voice announcement will be made that “the vehicle has arrived at the designated area and is ready to start battery swapping”.

[0022] Among them, the reflection area can be set through the radar. The radar determines the size, distance and other information of the obstacles in the change point channel through the received reflection signal. Different intruding persons or objects can be distinguished through filtering, segmentation, alignment, retrieval and feature extraction.

[0023] The V-groove has two photoelectric sensors for wheel position. When both sensors are blocked by wheels at the same time, the PLC will collect the signal and upload it to the cloud platform. The vehicle can be fine-tuned through the reflective mirror inside the station.

[0024] An intrusion detection auxiliary judgment method using a detection system of an unattended new energy battery swap station comprises the following steps:

[0025] Step 1: After the battery swap process is started, the intrusion detection gratings deployed at the entrance and exit of the battery swap station start the detection function;

[0026] Step 2: If the intrusion detection barrier does not detect any intrusion, go directly to step 3; if the intrusion detection barrier is triggered, the battery replacement process will be immediately suspended, and the voice will broadcast the reminder "Do not intrude during battery replacement". At the same time, the system will automatically generate and send a reminder work order to the background. The background operator will monitor the situation in the station through the camera to determine whether the risk has been eliminated. If the risk has been eliminated, go to step 3; if the risk has not been eliminated, request the background assistance and judge the risk status again until the risk is eliminated and go to step 3;

[0027] Step 3: During the battery swap process, the regional intrusion detection function conducts real-time detection. If no intrusion is detected, the battery swap status remains unchanged. If it is detected that the driver gets off the vehicle during the battery swap process, the regional intrusion camera cross-border intrusion and regional intrusion alarm will be triggered. The upper computer captures the alarm information and issues a command to suspend battery swap. At this time, the equipment will immediately stop the battery swap and broadcast a voice prompt "Driver, please do not get off the vehicle during battery swap". At the same time, the system will automatically generate and send a reminder work order to the background, and the background operator will conduct a risk assessment through camera monitoring. If the risk is not eliminated, it is necessary to request background assistance until the risk is eliminated. The battery swap can continue until the risk is eliminated.

[0028] The beneficial technical effects of the present invention are:

[0029] The present invention provides an unattended new energy battery swap station detection system and method, which significantly improves the operating efficiency and safety of the battery swap station. The system can not only effectively identify vehicle information and monitor vehicle location, but also detect and prevent intrusion in real time to ensure the safety of the battery swap process.

[0035] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0036] This specific embodiment discloses in detail a detection system and method for an unmanned new energy battery swap station.

[0037] A detection system for unattended new energy battery swap stations, such as Figure 1 As shown, including:

[0038] The main body 1 of the battery swap station includes a clear entrance and exit, providing a physical space for the battery swap process. A license plate recognition camera 2 is installed at the entrance of the main body of the battery swap station. A radar 3 is deployed on the top of the interior of the main body of the battery swap station, which can detect in real time whether there is a vehicle inside the battery swap station. The setting of the radar not only improves the accuracy of detection, but also realizes accurate monitoring of the vehicle position. Intrusion detection gratings are set at the entrance and exit of the battery swap station. These gratings can form a protection area. When a person or object enters the area, the grating will immediately trigger an alarm signal and upload the signal to the host computer. At the same time, intrusion detection cameras 4 are installed on the left and right sides of the internal entrance of the battery swap station, which can monitor the dynamic situation of vehicles and personnel in the battery swap station around the clock to ensure the safety of the battery swap process.

[0039] A V-groove photoelectric wheel detection sensor 5 is set on the internal ground of the battery swap station to detect whether the vehicle wheels are parked in the designated position. In actual applications, two V-groove photoelectric wheel detection sensors are usually set on the parking spaces of the battery swap station to detect the left and right front wheels of the vehicle respectively. When both sensors are blocked by the wheels at the same time, it means that the vehicle has been parked in place. At this time, the PLC will collect the signal and upload it to the cloud platform for recording.

[0040] As the core of the entire detection system, the host computer is responsible for receiving and analyzing detection signals from devices such as license plate recognition cameras, radars, intrusion detection gratings, intrusion detection cameras, and V-groove photoelectric wheel detection sensors. Based on these signals, the host computer will send corresponding control instructions to the execution end, including devices such as gates and voice broadcast boxes. The gate is set at the entrance of the main body of the battery swap station to control the entry and exit of vehicles; the voice broadcast box 6 is set inside the battery swap station to broadcast various prompt information during the battery swap process to the driver. Communication connection between the cloud platform and the host computer. The cloud platform can receive data sent by the host computer and store, analyze and process it. Through the cloud platform, remote monitoring of the operating status of the battery swap station can be achieved.

[0041] It is worth noting that Figure 1 The intrusion detection grating, gate, host computer and cloud platform are not reflected in the figure, but their setting locations and functions should be understood based on the above specific description.

[0042] The unattended new energy battery swap station detection system of the present invention has achieved remarkable technical effects. The system can not only effectively identify vehicle information and monitor vehicle location, but also detect and prevent intrusion in real time, ensuring the safety of the battery swap process. At the same time, through the remote monitoring and management functions of the cloud platform, the operating efficiency and management level of the battery swap station are further improved.

[0043] A vehicle entry judgment method using the detection system, such as Figure 2 As shown, the following steps are included: when the vehicle arrives at the battery swap station, the license plate recognition camera recognizes the vehicle license plate information and uploads the acquired data to the host computer, which searches the license plate to confirm whether the vehicle is eligible for battery swap. If the search result shows that the vehicle is not in the battery swap qualification list, a voice broadcast will be issued to prompt the driver to drive the vehicle into the battery swap station; if the search result shows that the vehicle is a valid battery swap vehicle, the system will send a command to lift the gate and a voice broadcast will be issued to prompt the driver to drive the vehicle into the battery swap station;

[0044] After the vehicle enters the battery swap station, the radar located on the top of the station detects whether there is a vehicle. If the radar does not detect the vehicle, a voice announcement will be made that “the vehicle has not reached the designated area”. If the radar detects the vehicle, a V-groove photoelectric sensor will be used to verify whether the vehicle is parked in the designated position. If the V-groove photoelectric sensor determines that the vehicle is not parked in place, a voice announcement will be made that “the vehicle has not reached the designated area”. If the V-groove photoelectric sensor determines that the vehicle is parked in place, a voice announcement will be made that “the vehicle has arrived at the designated area and is ready to start battery swapping”.

[0045] Among them, the reflection area can be set through the radar. The radar determines the size, distance and other information of the obstacles in the change point channel through the received reflection signal. Different intruding persons or objects can be distinguished through filtering, segmentation, alignment, retrieval and feature extraction.

[0046] The V-groove has two photoelectric sensors for wheel position. When both sensors are blocked by wheels at the same time, the PLC will collect the signal and upload it to the cloud platform. The vehicle can be fine-tuned through the reflective mirror inside the station.

[0047] An intrusion detection auxiliary judgment method using the detection system, such as Figure 3 As shown, the following steps are included:

[0048] Step 1: After the battery swap process is started, the intrusion detection gratings deployed at the entrance and exit of the battery swap station start the detection function;

[0049] Step 2: If the intrusion detection barrier does not detect any intrusion, go directly to step 3; if the intrusion detection barrier is triggered, the battery replacement process will be immediately suspended, and the voice will broadcast the reminder "Do not intrude during battery replacement". At the same time, the system will automatically generate and send a reminder work order to the background. The background operator will monitor the situation in the station through the camera to determine whether the risk has been eliminated. If the risk has been eliminated, go to step 3; if the risk has not been eliminated, request the background assistance and judge the risk status again until the risk is eliminated and go to step 3;

[0050] Step 3: During the battery swap process, the regional intrusion detection function conducts real-time detection. If no intrusion is detected, the battery swap status remains unchanged. If it is detected that the driver gets off the vehicle during the battery swap process, the regional intrusion camera cross-border intrusion and regional intrusion alarm will be triggered. The upper computer captures the alarm information and issues a command to suspend battery swap. At this time, the equipment will immediately stop the battery swap and broadcast a voice prompt "Driver, please do not get off the vehicle during battery swap". At the same time, the system will automatically generate and send a reminder work order to the background, and the background operator will conduct a risk assessment through camera monitoring. If the risk is not eliminated, it is necessary to request background assistance until the risk is eliminated. The battery swap can continue until the risk is eliminated.
