[0040] A battery swapping system is a facility specifically designed to provide battery replacement services for vehicles. The battery swapping system uniformly manages and services a large number of batteries through a centralized charging station. These batteries receive services such as centralized storage, charging, and unified distribution within the battery swapping system to provide rapid battery replacement for vehicles. The essence of the battery swapping system is to explore the full life cycle value of the battery and realize the redistribution of the interests of enterprises and consumers. Simply put, instead of charging, the vehicle directly meets its cruising range by replacing the battery. Such a facility that separates the vehicle and the battery for energy replenishment is called a battery swapping system.

[0041] During the operation of the battery swapping system, issues such as environmental climate, vehicle status, and biological invasion need to be considered. Moreover, there are many battery swapping devices inside the battery swapping system. Therefore, the battery swapping system has relatively high requirements for the reliability during operation. In related technologies, to improve the reliability of the battery swapping system during operation, durability tests are carried out on the battery swapping devices inside the battery swapping system before it is put into operation.

[0042] However, technicians found that although conducting durability tests on the battery swapping devices can improve the reliability of the battery swapping system to a certain extent, it is impossible to monitor the operating status of the battery swapping devices, thus unable to detect and prevent the failure of the battery swapping devices in advance, which is likely to cause safety accidents.

[0043] Based on the related technologies, how to monitor the operating status of the battery swapping devices is an urgent problem to be solved currently. The embodiments of this application provide a battery swapping system. Referring to Figure 1 、 Figure 2 and Figure 3 , the battery swapping system includes a storage station 1, a work station 2, a shuttle device 3, and an information collection device 4. The storage station 1 includes a storage bin 11 and a stacker 12 inside the storage bin 11. The storage bin 11 is used to store batteries, and the stacker 12 is used to pick up and place batteries; the work station 2 includes a work bin 21 and a vehicle lifter 22 inside the work bin 21. The vehicle lifter 22 is arranged at the battery swapping position of the work bin 21 to lift the vehicle; the shuttle device 3 includes a shuttle car 31 and a battery swapping module 32 arranged on the shuttle car 31. The shuttle car 31 shuttles between the storage bin 11 and the work bin 21 to transport batteries, and the battery swapping module 32 is used to disassemble or install batteries; the information collection device 4 includes a vibration collection component 41 and a sound collection component 42. The vibration collection component 41 is arranged at the driving mechanism of at least one of the stacker 12, the vehicle lifter 22, the shuttle car 31, and the battery swapping module 32 to collect vibration information at the corresponding transmission mechanism; the sound collection component 42 is arranged in at least one of the storage bin 11 and the work bin 21 to collect sound information in the corresponding space.

[0044] In the embodiment of the present application, a battery rack and a plug-in control mechanism may further be provided in the storage bin 11. The battery rack is provided with storage positions for storing batteries. The output part of the plug-in control mechanism is connected to the charging plug of the battery rack to drive the charging plug of the battery rack to insert into or pull out of the charging socket. In addition, a charger is further provided in the storage bin 11 for charging and discharging the batteries on the battery rack to detect the health status of the batteries.

[0045] In the technical solution provided by the embodiment of the present application, the battery swapping system includes a storage station 1, a work station 2, a shuttle device 3, and an information acquisition device 4. The information acquisition device 4 includes a vibration acquisition component 41 and a sound acquisition component 42. Among them, the storage station 1 includes a storage bin 11 for storing batteries and a stacker 12 for picking and placing batteries. The work station 2 includes a work bin 21 and a vehicle lifter 22 for lifting the vehicle. The shuttle device 3 includes a shuttle car 31 for transporting batteries and a battery swapping module 32 for disassembling or installing batteries. When the vehicle is swapping batteries, first, the vehicle drives into the battery swapping position of the work bin 21, and the vehicle lifter 22 lifts the vehicle to expose the battery compartment at the bottom of the vehicle; then, the shuttle car 31 drives under the vehicle, and the battery swapping module 32 on the shuttle car 31 disassembles the battery on the vehicle, and the shuttle car 31 transports the removed battery to the storage bin 11; then, the stacker 12 takes the battery on the shuttle car 31 and places the fully charged battery on the shuttle car 31; finally, the shuttle car 31 transports the fully charged battery under the vehicle, and the battery swapping module 32 on the shuttle car 31 installs the fully charged battery on the vehicle, and the vehicle lifter 22 lowers the vehicle. Thus, the battery swapping system completes the replacement of the battery on the vehicle. The vibration acquisition component 41 is arranged at the driving mechanism of at least one of the stacker 12, the vehicle lifter 22, the shuttle car 31, and the battery swapping module 32 to acquire the vibration information at the corresponding transmission mechanism. In this way, the wear trend of the driving mechanism on the corresponding device can be analyzed through the vibration information, so as to predict the service life of the driving mechanism, so as to perform maintenance in the early stage when the driving mechanism fails. In addition, the vibration information can also be used to evaluate the performance and operating status of the driving mechanism on the corresponding device, so as to optimize the driving mechanism. The sound acquisition component 42 is arranged in at least one of the storage bin 11 and the work bin 21 to acquire the sound information in the corresponding space. Here, the sound information can reflect the operating status and health condition of the battery swapping equipment in the corresponding space. It can be analyzed according to the sound information whether there are problems such as excessive wear, fatigue, and cracks inside the corresponding equipment. It can also be judged whether the corresponding equipment is in a normal operating state according to the frequency and amplitude of the sound information, so as to help the maintenance personnel timely understand the maintenance requirements of the battery swapping equipment, so as to perform maintenance in the early stage when the battery swapping equipment fails. In summary, the battery swapping system can respectively monitor the vibration information and sound information of the battery swapping equipment through the information acquisition device 4, so as to realize the monitoring of the operating status of the battery swapping equipment.

[0046] In the embodiments of the present application, the driving mechanism refers to a mechanism that transmits power to the working part of a machine to achieve the expected motion and function. When the stacker 12, the vehicle lifter 22, the shuttle car 31, and the battery swapping module 32 are working, the driving mechanisms of the stacker 12, the vehicle lifter 22, the shuttle car 31, and the battery swapping module 32 will all generate vibrations. The vibration acquisition component 41 can selectively acquire vibration information according to actual needs. For example, the vibration acquisition component 41 can be respectively arranged at the driving mechanisms of the stacker 12, the vehicle lifter 22, the shuttle car 31, and the battery swapping module 32 to acquire the vibration information generated by the driving mechanisms on the stacker 12, the vehicle lifter 22, the shuttle car 31, and the battery swapping module 32; it can also be selectively arranged on the stacker 12, the vehicle lifter 22, and the shuttle car 31 to acquire the vibration information generated by the driving mechanisms on the stacker 12, the vehicle lifter 22, and the shuttle car 31; or it can be independently arranged at the driving mechanism of the stacker 12 to acquire the vibration information generated by the driving mechanism on the stacker 12. The embodiments of the present application do not limit this.

[0047] In the embodiments of the present application, there are various possibilities for the installation position of the sound acquisition component 42. For example, the sound acquisition component 42 can be only arranged in the storage bin 11, or only arranged in the working bin 21, or can be arranged in both the storage bin 11 and the working bin 21 at the same time. The embodiments of the present application do not limit this.

[0048] Referring to Figure 1 and Figure 2 In the embodiments of the present application, the battery swapping system may further include a server 5. The vibration acquisition component 41 and the sound acquisition component 42 are respectively electrically connected to the server 5. The vibration acquisition component 41 transmits the acquired vibration information to the server 5. The sound acquisition component 42 transmits the acquired sound information to the server 5.

[0049] In the embodiments of the present application, the vibration acquisition component 41 and the sound acquisition component 42 are electrically connected to the server 5 for the purpose of transmitting the acquired vibration information and sound information to the server 5. Therefore, there are various possibilities for the connection method between the vibration acquisition component 41 and the sound acquisition component 42 and the server 5. For example, the vibration acquisition component 41 can be connected to the server 5 through a signal transmission line, or can be electrically connected to the server 5 through a wireless transmission module. The sound acquisition component 42 can be connected to the server 5 through a signal transmission line, or can be electrically connected to the server 5 through a wireless transmission module. The embodiments of the present application do not limit this.

[0050] In the embodiments of the present application, the stacker 12, the vehicle lifter 22, the shuttle car 31, and the battery swapping module 32 are all core devices in the battery swapping process, and all need to bear large loads during the battery swapping process. Therefore, the probability of failure of the stacker 12, the vehicle lifter 22, the shuttle car 31, and the battery swapping module 32 during the battery swapping process is relatively high. The vibration acquisition component 41 selects the stacker 12, the vehicle lifter 22, the shuttle car 31, and the battery swapping module 32 as the monitoring objects, which can not only obtain the overall operating state of the battery swapping system through the vibration information of these devices, but also avoid occupying too much space for the collected vibration information due to the excessive number of monitoring objects, so as to avoid affecting the storage and analysis of these information by the server 5 and reduce the operating cost of the battery swapping system.

[0051] Referring to Figure 2 , in the embodiments of the present application, the information acquisition device 4 may further include a device gateway. The vibration acquisition component 41 may include a vibration acquisition card, and the sound acquisition component 42 may include a sound acquisition card. After the vibration acquisition component 41 acquires the vibration information, the acquired vibration information is first transmitted to the device gateway through the vibration acquisition card, and then the device gateway transmits the vibration information to the server 5. After the sound acquisition component 42 acquires the sound information, the acquired sound information is first transmitted to the device gateway through the sound acquisition card, and then the device gateway transmits the sound information to the server 5.

[0052] In the embodiments of the present application, since the vibration information acquired by the vibration acquisition component 41 has a high frequency and occupies a large space, the vibration acquisition component 41 needs to preprocess the vibration data before transmitting the vibration information to the server 5. The preprocessing process includes extracting the vibration data when the driving mechanism is in the load state in the vibration information and extracting the time-domain characteristics and frequency-domain characteristics of the vibration data.

[0053] It should be noted that in the embodiments of the present application, the driving mechanism being in the load state means the working state of the driving mechanism under the action of an external load. Here, the external load may be a structure within the battery swapping system, such as the carrier 121 of the stacker 12. Since the carrier 121 is always connected to the carrier 121 when the stacker 12 is working, as long as the traveling driving structure 123 drives the carrier 121 to move, the traveling driving structure 123 is in the load state. The external load may also be a structure outside the battery swapping system, such as a vehicle entering the battery swapping system for battery swapping. Since there is a certain distance between the lifting member 222 and the vehicle when the driving mechanism of the vehicle lifter 22 drives the lifting member 222 to lift the vehicle, the driving mechanism of the vehicle lifter 22 is in the no-load state during this process; after the vehicle is carried on the lifting member 222, the driving mechanism of the vehicle lifter 22 is in the load state.

[0054] In the embodiments of the present application, the stacker 12, the vehicle lifter 22, the shuttle car 31, and the battery swapping module 32 are all controlled by a Programmable Logic Controller (PLC). The vibration information processing module can extract the vibration data of the drive system in the load state from the vibration information according to the step number of the programmable logic controller from the vibration sensor.

[0055] In the embodiments of the present application, the time-domain features may include one or several of the maximum value, minimum value, peak-to-peak value, average value, root mean square value, standard deviation, variance, skewness, kurtosis, waveform index, pulse index, peak index, and margin index, and the embodiments of the present application do not limit this. The frequency-domain features may include one or several of the center frequency, mean square frequency, and frequency variance, and the embodiments of the present application do not limit this. In an implementable manner provided by the embodiments of the present application, the time-domain features may include the maximum value, minimum value, peak-to-peak value, average value, root mean square value, standard deviation, variance, skewness, kurtosis, waveform index, pulse index, peak index, and margin index. The frequency-domain features include the center frequency, mean square frequency, and frequency variance. The time-domain features and the frequency-domain features together include sixteen-dimensional features.

[0056] In the embodiments of the present application, the information acquisition device 4 may include a vibration information processing module, and the vibration information processing module can extract the vibration data of the drive mechanism in the load state from the vibration information. Here, the vibration data may contain important information about the health status of the drive mechanism, such as problems like structural damage, poor balance, looseness, or wear. When the drive mechanism is in the load state, the load will amplify the vibration signal in the vibration data, making the vibration signal easier to monitor and analyze, so that it is easier to detect in advance in the early stage of the failure of the drive mechanism, so as to facilitate the maintenance of the drive mechanism about to fail in advance, further improving the safety during the operation of the battery swapping system. The vibration information processing module also extracts the time-domain features and frequency-domain features of the vibration data. Here, the time-domain feature refers to the characteristics of the vibration signal in the vibration data on the time axis, which describes the behavior of the vibration signal in the vibration data changing with time. The frequency-domain feature refers to the characteristics of the vibration signal in the vibration data on the frequency axis, which describes the composition of the vibration signal frequency in the vibration data. When the server 5 analyzes the vibration data, combining the time-domain features and the frequency-domain features can more comprehensively understand and analyze the vibration data. In addition, the vibration information processing module transmits the preprocessed vibration information to the server 5, which can reduce the storage requirements for the server 5, facilitate the long-term storage of the preprocessed vibration information by the server 5, and is beneficial for the server 5 to conduct long-term operation trend analysis of the battery swapping system and formulate predictive maintenance strategies.

The walking driving structure 123 and the lifting and lowering driving structure 124 can generate vibration information. Here, the walking drive structure 123 and the lifting and lowering drive structure 124 both need to bear a large load when working. The information collection device 4 collects the vibration information of the walking drive structure 123 and the lifting and lowering drive structure 124 to obtain more specific vibration information of the drive mechanism on the stacker 12, which is convenient for analyzing the wear trend of the walking drive structure 123 and the lifting and lowering drive structure 124, thereby predicting the service life of the walking drive structure 123 and the lifting and lowering drive structure 124, so as to facilitate early maintenance of the walking drive structure 123 and the lifting and lowering drive structure 124.

By disposing the first vibration sensor 411 at the outer shell of the traveling speed reducer 1232 and the second vibration sensor 412 at the outer shell of the lifting speed reducer 1242, the distance between the vibration acquisition assembly 41 and the acquisition target point can be shortened, thereby reducing the attenuation of vibration signals during transmission and improving the acquisition accuracy of the vibration acquisition assembly 41. In addition, the structure of the speed reducer is usually more robust than that of the motor. Therefore, the speed reducer can provide better signal isolation, thereby reducing the interference of external noise.

The vibration acquisition component 41 detects the vibration information on the lifting transmission component 322, and can analyze the energy loss condition of the lifting transmission component 322 through the vibration magnitude and vibration frequency, such as frictional loss, elastic deformation, etc.; it can also judge whether there are cracks, fractures or other structural integrity problems inside the transmission structure through whether the vibration is abnormal, so as to predict the service life of the lifting transmission component 322, so as to facilitate maintenance in the early stage when the lifting transmission component 322 fails. The vibration acquisition component 41 can also be respectively disposed on the lifting power output component 321 and the lifting transmission component 322. In this way, the vibration acquisition component 41 can simultaneously detect the vibration information on the lifting power output component 321 and the lifting transmission component 322, and can simultaneously predict the service lives of the lifting power output component 321 and the lifting transmission component 322, so as to facilitate maintenance in the early stage when the lifting power output component 321 and the lifting transmission component 322 fail, and further improve the reliability of the lifting drive structure during operation.

[0081] Refer to Figure 8, in the embodiment of the present application, the lifting power output assembly 321 includes a lifting drive motor 3211 and a lifting speed reducer 3212. The lifting transmission assembly 322 includes a lead screw 3221, a nut slider 3222 and a scissor structure 3223. The power output shaft of the lifting drive motor 3211 is drivingly connected to the motor end of the lifting speed reducer 3212. The output end of the lifting speed reducer 3212 is drivingly connected to the lead screw 3221. The nut slider 3222 is arranged on the lead screw 3221, and the nut slider 3222 is connected to the disassembly and assembly structure through the scissor structure 3223. The vibration acquisition assembly 41 includes a sixth vibration sensor 416. The sixth vibration sensor 416 is respectively arranged on the outer shell of the lifting speed reducer 3212, the lead screw 3221 and the nut slider 3222 to acquire the vibration information at the driving mechanism of the battery swapping module 32.

[0082] , in the embodiment of the present application, the lifting power output assembly 321 includes a lifting drive motor 3211 and a lifting speed reducer 3212. The lifting speed reducer 3212 can convert the high speed and low torque of the lifting drive motor 3211 into low speed and high torque to meet the specific requirements of the driving mechanism of the battery swapping module 32 for speed and torque. The lifting transmission assembly 322 includes a lead screw 3221, a nut slider 3222 and a scissor structure 3223. The power output by the lifting power output assembly 321 is sequentially transmitted to the disassembly and assembly structure through the lead screw 3221, the nut slider 3222 and the scissor structure 3223 to drive the disassembly and assembly structure to lift. The vibration acquisition assembly 41 includes a sixth vibration sensor 416. The sixth vibration sensor 416 is respectively arranged on the outer shell of the lifting speed reducer 3212, the lead screw 3221 and the nut slider 3222 to acquire the vibration information at the driving mechanism of the battery swapping module 32. By arranging the sixth vibration sensor 416 on the outer shell of the lifting speed reducer 3212, the lead screw 3221 and the nut slider 3222 respectively, the distance between the vibration acquisition assembly 41 and the acquisition target point can be shortened, thereby reducing the attenuation of the vibration signal during transmission and improving the acquisition accuracy of the vibration acquisition assembly 41. In addition, the structure of the speed reducer is usually more robust than that of the motor. Therefore, the speed reducer can provide better signal isolation, thereby reducing the interference of external noise.

[0083] , in the embodiment of the present application, the type of the sound acquisition assembly 42 has various possibilities. For example, the sound acquisition assembly 42 can be a microphone array or a capacitive microphone. The embodiment of the present application does not limit this. In addition, when the sound acquisition assembly 42 acquires sound, the sampling frequency of the sound acquisition assembly 42 has various possibilities. For example, the sampling frequency of the sound sensor can be 120 kHz, 128 kHz, or 136 kHz. The embodiment of the present application does not limit this.

[0084] Refer to Figure 3, in the embodiment of the present application, the sound collection component 42 includes a first microphone array 421 and a second microphone array 422. At least one group of the first microphone arrays 421 is arranged in the storage bin 11 to collect the sound information in the storage bin 11, and at least one group of the second microphone arrays 422 is arranged in the working bin 21 to collect the sound information in the working bin 21.

[0085] In the embodiment of the present application, the number of the first microphone arrays 421 and the second microphone arrays 422 has multiple possibilities. For example, one group, three groups or five groups of the first microphone arrays 421 can be arranged in the storage bin 11; one group, three groups or five groups of the second microphone arrays 422 can be arranged in the working bin 21. The embodiment of the present application does not limit this.

[0086] In the embodiment of the present application, the sound collection component 42 includes a first microphone array 421 and a second microphone array 422. At least one group of the first microphone arrays 421 is arranged in the storage bin 11, and at least one group of the second microphone arrays 422 is arranged in the working bin 21. In this way, the first microphone array 421 collects the sound information emitted by the power exchange equipment in the storage bin 11 during operation, such as the stacker 12, etc., and the second microphone array 422 collects the sound information emitted by the power exchange equipment in the working bin 21 during operation, such as the vehicle lifter 22, the rotary platform 23, etc. When the shuttle car 31 travels back and forth between the storage bin 11 and the working bin 21, the sound information of the shuttle car 31 can also be collected by the first microphone array 421 and the second microphone array 422. The sound information emitted by the power exchange equipment during operation can reflect the operating state and health condition of the power exchange equipment. By collecting and analyzing the sound information emitted by at least one of the stacker 12, the vehicle lifter 22, the shuttle car 31, the rotary platform 23 and the power exchange module 32, it is possible to analyze whether there are problems such as excessive wear, fatigue and cracks inside the corresponding equipment, and it is also possible to judge whether the corresponding equipment is in a normal operating state according to the frequency and amplitude of the sound information, so as to help the maintenance personnel understand the maintenance requirements of the power exchange equipment in time, so as to perform maintenance in the early stage when the power exchange equipment fails.

[0087] In the embodiment of the present application, the first microphone array 421 and the second microphone array 422 convert the captured sound into an electrical signal (voltage signal / current signal) and output it. The sound collection component converts the electrical signals at the first microphone array 421 and the second microphone array 422 into digital signals, and collects and stores them.

[0088] In the embodiments of the present application, since the frequency of the sound information collected by the sound collection component 42 is high and it occupies a large space, the information collection device 4 needs to preprocess the sound information before transmitting it to the server 5. Therefore, the information collection device 4 may include a sound processing module, and the sound processing module may extract the sound data when the battery swapping device is in a loaded state from the sound information, and extract the sound features from the sound data.

[0089] It should be noted that in the embodiments of the present application, the battery swapping device being in a loaded state means that the battery swapping device is consuming a certain amount of energy during operation. For example, the stacker 12 being in a loaded state usually means that the stacker 12 is in the process of performing a battery handling task. The vehicle lifter 22 being in a loaded state usually means that the vehicle lifter 22 is in the process of lifting or supporting a vehicle. The shuttle car 31 being in a loaded state usually means that the shuttle car 31 is in the process of performing a battery handling task between the storage bin 11 and the working bin 21. The rotating platform 23 being in a loaded state usually means that the rotating platform 23 is rotating the shuttle car 31. The battery swapping module 32 being in a loaded state usually means that the driving mechanism of the battery swapping module 32 drives the disassembly and assembly structure to lift and lower.

[0090] In the embodiments of the present application, the stacker 12, the vehicle lifter 22, the shuttle car 31, the rotating platform 23, and the battery swapping module 32 are all controlled by a programmable logic controller, and the sound information processing module can extract the sound data when the battery swapping device is in a loaded state from the sound sensor according to the step number of the programmable logic controller.

[0091] In the embodiments of the present application, when the sound processing module extracts the sound features from the sound data, it can use Mel-Frequency Cepstral Coefficients (MFCCs) to extract the sound features from the sound data. Mel-Frequency Cepstral Coefficients simulate the way the human auditory system perceives sound frequencies. Mel-Frequency Cepstral Coefficients convert the linear spectrum into a logarithmic spectrum based on the Mel scale, and then perform a discrete cosine transform to obtain a set of feature vectors, and these vectors effectively express the sound features in the sound data.

[0092] In the embodiments of the present application, the calculation steps of the Mel Frequency Cepstral Coefficient (MFCC) are as follows: First, pre-emphasize the sound data. The pre-emphasis can be achieved using a first-order high-pass filter. In this way, the high-frequency components in the sound data can be increased, making the spectrum smoother. Next, frame and window the sound data to divide the sound signal into short-time frames and apply a window function to reduce the overlapping effect between frames. When framing and windowing the sound data, the number of frame transformations and the type of window function can be determined according to the type of the battery swapping device. For example, the number of turns of the frame can be selected as 2, the frame length can be 1 second, and each frame has 20,000 data points. The Hanning window can be selected as the window function. Then, calculate the Mel Frequency Cepstral Coefficient for each working condition of the battery swapping device 1 and perform power spectrum estimation for each frame. Next, filter with a Mel filter to obtain the Mel spectrum. Then, perform a logarithmic transformation on the Mel spectrum to simulate the non-linear response of the human auditory system. Next, perform a discrete cosine transform on the logarithmic Mel spectrum, retain the 2nd to 13th coefficients of the discrete cosine transform, and discard the others. Use the energy of each frame and the 2nd to 13th coefficients of the discrete cosine transform as features to obtain a 13-dimensional feature vector. Then, calculate the 13-dimensional vectors of the first-order differential Mel Frequency Cepstral Coefficient (ΔMFCC) and the second-order differential Mel Frequency Cepstral Coefficient (Δ 2 MFCC) respectively, and jointly combine them into a 39-dimensional feature vector. Finally, calculate the 39-dimensional feature vector for each frame of the sound data when the battery swapping device 1 is in the load state and calculate the average value.

[0093] To improve the robustness of the model, reduce the model parameters and modeling time, the principal component analysis method can be used to reduce the dimension of the calculated 39-dimensional feature vector, and select the features with the cumulative variance contribution rate (Cumulative Percentage Variance, CPV) of the principal components greater than 85% as the sound features reflecting the battery swapping device 1.

[0094] In the embodiments of the present application, at least one of the stacker 12, the vehicle lifter 22, the shuttle car 31, the rotary platform 23, and the battery swapping module 32 has a servo control system, and the information acquisition device 4 can acquire the servo control quantity of the servo control system.

[0095] It should be noted that the stacker 12, the vehicle lifter 22, the shuttle car 31, the rotary platform 23, and the battery swapping module 32 all need to be controlled by a control system during operation, and there are various possibilities for the selection of the control system. For example, alternatively, at least one of the stacker 12, the vehicle lifter 22, the shuttle car 31, the rotary platform 23, and the battery swapping module 32 has a frequency converter control system, and the information acquisition device 4 can also acquire the frequency converter control quantity of the frequency converter control system.

[0096] In the embodiments of the present application, the controlled objects of the servo control systems on the stacker 12, vehicle lifter 22, shuttle car 31, rotary platform 23, and battery swapping module 32 are all servo motors. When the information acquisition device 4 acquires the servo control quantities of the servo control systems, it can acquire the speed, current, torque, acceleration, and semi-closed-loop stroke position of the servo motors, or it can only acquire the speed, current, and semi-closed-loop stroke position of the servo motors. The embodiments of the present application do not limit this.

[0097] In the embodiments of the present application, the information acquisition device 4 may include a programmable logic controller, and the server 5 obtains the servo control quantities of the servo motors through the programmable logic controller. When the information acquisition device 4 acquires the servo control quantities, the information acquisition device 4 can determine the sampling period according to actual needs. For example, the sampling period of the information acquisition device 4 can be 50 milliseconds, or 100 milliseconds, or 150 milliseconds. The embodiments of the present application do not limit this.

[0098] In the embodiments of the present application, at least one of the stacker 12, vehicle lifter 22, shuttle car 31, rotary platform 23, and battery swapping module 32 has a servo control system. The servo control system can achieve high-precision position and speed control, thereby improving the control accuracy of the battery swapping equipment in the battery swapping system. The information acquisition device 4 can acquire the servo control quantities of the servo control systems. Here, the servo motor is the power source when the stacker 12, vehicle lifter 22, shuttle car 31, rotary platform 23, and battery swapping module 32 are working. By acquiring and analyzing the servo control quantities of the servo control systems, it is possible to detect in advance in the early stage when the servo motor fails, so as to repair the servo motor that is about to fail in advance, thereby improving the reliability of the power sources on the stacker 12, vehicle lifter 22, shuttle car 31, rotary platform 23, and battery swapping module 32 during the battery swapping process.

[0099] Refer to Figure 9 , in the embodiments of the present application, the workstation 2 further includes a vehicle centering mechanism 24, and the vehicle centering mechanism 24 includes a baffle 241 and a pulley set 242. The baffle 241 is usually installed on the ground of the battery swapping system to limit the movement range of the vehicle. The pulley set 242 is used to guide the tires of the vehicle so that the vehicle can move along a predetermined trajectory, thereby achieving the purpose of precise positioning.

[0100] In the embodiments of the present application, the stacker 12, vehicle lifter 22, shuttle car 31, rotary platform 23, and battery swapping module 32 in the battery swapping equipment are the key monitoring objects, and the vehicle centering mechanism 24 is the auxiliary monitoring object. The components in the vehicle centering mechanism 24 can improve reliability by increasing the design margin and threshold monitoring.

[0101] Refer to Figure 1 and Figure 2, in the embodiments of the present application, an electricity meter, an air conditioner, an Uninterruptible Power Supply (UPS), fire-fighting equipment, temperature and humidity detection equipment, a heater, and a hot air curtain are also provided in the battery swapping system. The information acquisition device 4 can respectively acquire the voltage / current signals of the electricity meter, the air conditioner, the UPS, the fire-fighting equipment, the temperature and humidity detection equipment, the heater, and the hot air curtain, and transmit the acquired voltage / current signals to the server 5.
