[0002] At present, electric engineering machinery equipment (hereinafter referred to as engineering machinery) operating in tunnels has a limited use time after a single charge due to the limitation of battery energy density. When the battery is exhausted, there are two options: direct charging and battery replacement. In the long and deep tunnel environment, as the working surface continues to advance, it will not be feasible to travel back and forth inside and outside the tunnel for power replenishment. The installation of fixed charging equipment in the tunnel requires the formulation of relevant safety standards and operating procedures, which is difficult to implement and takes a long time. Therefore, exploring mobile battery replacement technology in tunnels will become the main way to solve the problems of endurance and charging of new energy electric engineering machinery used in tunnel construction.

[0003] In response to this situation, some construction machinery manufacturers have produced mobile battery swap vehicles to solve the problem of battery replacement in tunnels.

[0046] Based on the above-mentioned embodiments of the present disclosure, in the absence of explicit negation or conflict, the technical features of one embodiment may be beneficially combined with one or more other embodiments.

[0047] During the research process, the inventor found that the composition of the existing battery swapping system is too complicated and must rely on the master control system as a unified information processing center. Information interaction is based on 4G / 5G mobile communication technology. However, the construction site in the tunnel has not established a unified management and control platform, and does not have the conditions for realizing 4G / 5G mobile communication. The engineering machinery to be battery swapped and the mobile battery swapping vehicle cannot realize information exchange, the battery swapping process cannot be centrally detected and controlled, and the battery swapping efficiency is low.

[0048] To solve the above problems, firstly, the present disclosure provides a battery replacement system, such as Figure 1 and Figure 2 As shown, including:

[0049] The mobile battery-swapping vehicle 100 includes a first signal transceiver terminal 11 and a backup battery. The first signal transceiver terminal 11 includes an industrial computer 111 and a wireless access point AP112. The industrial computer 111 cooperates with the wireless access point AP112 to complete the construction of a local area network; and

[0050] The construction machinery 200 includes a second signal transceiver terminal 21 and a battery to be replaced. The second signal transceiver terminal 21 and the first signal transceiver terminal 11 are both configured to receive and transmit wireless signals through a local area network to achieve information interaction between the mobile battery exchange vehicle 100 and the construction machinery 200, so that the mobile battery exchange vehicle 100 replaces the battery to be replaced of the construction machinery 200 with a spare battery.

[0051] Specifically, the first signal transceiver terminal 11 is responsible for establishing a local area network and receiving information from the engineering machinery 200, such as the remaining battery power, the working status of the engineering machinery 200, etc. The industrial computer 111 and the wireless access point AP112 cooperate to create a stable wireless network environment in a relatively closed space such as a tunnel; at the same time, the first signal transceiver terminal 11 is connected to the first vehicle controller 10 of the mobile battery swap vehicle 100, and transmits the battery swap action command to the engineering machinery 200 to realize information interaction between the two. The second signal transceiver terminal 21 transmits wireless signals to the outside, transmits the information of the engineering machinery 200 to the mobile battery swap vehicle 100 through the local area network, and receives information from the mobile battery swap vehicle 100.

[0052] Specifically, the construction machinery 200 is an electric or hybrid construction machinery that uses a battery as a power source, and the construction machinery can be constructed in a tunnel and replace the battery when the power battery is insufficient, such as an electric excavator, an electric loader, etc. Optionally, the battery to be replaced can be a low-power battery or a faulty battery.

[0053] Specifically, the mobile battery exchange vehicle 100 is used to replace the battery of the engineering machinery 200 in the tunnel, that is, to replace the battery to be replaced with the spare battery. The battery to be replaced is detachably mounted on the body of the engineering machinery. The first signal transceiver terminal 11 and the second signal transceiver terminal 21 are both vehicle-mounted signal transceiver terminals.

[0054] Specifically, the industrial computer 111 is used to process the reader / writer data of the wireless access point AP, and to exchange information with the first vehicle controller 10 of the mobile battery-swapping vehicle 100. The wireless access point AP is used to cooperate with the industrial computer to complete the construction and management of the local area network. Optionally, the local area network includes a WLAN local area network or a Bluetooth local area network. Optionally, the engineering machinery 200 may include one or more, or one or more.

[0055] Specifically, the battery replacement system disclosed in the present invention can be used on a large scale in tunnel scenarios, can realize the rapid replacement of batteries, effectively reduce the complexity of manual operation, and make battery replacement convenient and fast. The system is established through manual operation and a network for communication. The battery replacement process does not require the use of any auxiliary tools. One operator can complete the battery replacement process, thereby greatly improving the battery replacement efficiency and thus improving the efficiency of vehicle use.

[0056] This embodiment sets an industrial computer 111 and a wireless access point AP112 on the mobile battery swap vehicle 100. Even in a tunnel environment without signals and a unified control platform, communication can be established between the mobile battery swap vehicle 100 and the engineering machinery 200 to ensure smooth transmission of battery swap information, realize point-to-point or point-to-multipoint communication within the coverage area of ​​the local area network, and realize centralized control of the battery swap system. It can meet the battery swap needs of the engineering machinery 200 and improve the automation level and efficiency of the battery swap system. By replacing the battery of the engineering machinery 200, the utilization efficiency of the engineering machinery 200 can be improved, the disadvantage of the engineering machinery 200 not being able to work while charging can be avoided, and the control accuracy of the entire vehicle can be improved. The mobile battery swap vehicle 100 can quickly deliver the spare battery to the engineering machinery 200 that needs to replace the battery, and replace the battery safely and quickly.

[0057] In some embodiments, Figure 1 As shown, the engineering machinery 200 also includes a battery replacement controller 22 and a battery box locking control mechanism 220. The battery box locking control mechanism 220 is communicatively connected to the battery replacement controller 22. The battery replacement controller 22 is communicatively connected to the second signal transceiver terminal 21. The battery replacement controller 22 is configured to enable the battery box locking control mechanism 220 to unlock the battery to be replaced when the second signal transceiver terminal 21 receives an unlocking command; and the battery replacement controller 22 is configured to enable the battery box locking control mechanism 220 to lock the spare battery when the second signal transceiver terminal 21 receives a locking command.

[0058] Specifically, the battery box locking control mechanism 220 is connected to the battery replacement controller 22. When the engineering machinery 200 executes the battery replacement command, the battery box locking control mechanism 220 will unlock the battery to be replaced so that the battery replacement device 12 of the mobile battery replacement vehicle 100 can replace and replenish the power of the engineering machinery 200. When the battery replacement is completed, the battery box locking control mechanism 220 will lock the power battery to prevent the battery from loosening during the operation of the engineering machinery 200.

[0059] This embodiment controls the battery box locking control mechanism 220 to unlock / lock the battery through the battery replacement controller 22, which can automatically unlock or lock the battery on the engineering machinery 200 according to needs, thereby improving the automation level of battery replacement and improving the working efficiency and safety of the battery replacement system.

[0060] In some embodiments, Figure 1 As shown, the engineering machine 200 further includes a battery management system 23 , which is configured to dynamically monitor the performance parameters of the battery to be replaced and present the performance parameters of the battery to be replaced on an onboard display screen of the engineering machine 200 .

[0061] Specifically, the performance parameters of the battery to be replaced may include information such as battery charge and battery temperature. For example, the battery management system 23 is used to dynamically monitor the remaining charge of the power battery. The detected battery charge will be presented on the on-board display screen of the engineering machinery user to facilitate the operator to determine the timing of battery replacement.

[0062] The battery management system 23 of this embodiment monitors the performance parameters of the battery in real time, allowing the operator to check the battery status at any time through the vehicle-mounted display screen, reasonably arrange work plans and battery replacement plans, and extend the battery life; at the same time, real-time monitoring of the battery status helps to take safety measures in time to prevent dangerous situations such as overheating and short circuits, thereby ensuring the safety of the working environment.

[0063] In some embodiments, Figure 1 As shown, the engineering machinery 200 also includes a second vehicle controller 20 , and a second signal transceiver terminal 21 , a battery replacement controller 22 and a battery management system 23 are all communicatively connected to the second vehicle controller 20 .

[0064] Specifically, the second vehicle controller 20 serves as the core control unit, which is connected to the battery swap controller 22, the battery management system 23, and the second signal transceiver terminal 21, and uniformly manages the data and instructions of each subsystem. The second vehicle controller 20 aggregates the information and distributes it to the battery swap controller 22, the battery management system 23, and the second signal transceiver terminal 21 to achieve integrated control of the construction machinery 200.

[0065] The second vehicle controller 20 of this embodiment can achieve high integration and centralized management of the battery swapping system, thereby improving the operating efficiency and safety of the battery swapping system.

[0066] In some embodiments, Figure 1 As shown, the mobile battery exchange vehicle 100 also includes a battery exchange device 12, which is configured to remove the battery to be replaced from the engineering machinery 200 to the mobile battery exchange vehicle 100, and install the spare battery from the mobile battery exchange vehicle 100 to the engineering machinery 200.

[0067] Specifically, the battery exchange device 12 of the mobile battery exchange vehicle 100 is used to realize the battery exchange of the engineering machinery. For example, the battery exchange process may include the battery exchange device 12 removing the depleted battery of the engineering machinery 200, placing the depleted battery on the battery base of the mobile battery exchange vehicle 100, taking the fully charged spare battery out of the battery base of the mobile battery exchange vehicle 100, and installing the fully charged battery on the engineering machinery 200. Optionally, the battery exchange device 12 may transfer the battery by any method such as hoisting transfer or clamp transfer.

[0068] The battery replacement device 12 of this embodiment can realize automatic removal and installation of the battery, reduce manual intervention, and improve battery replacement efficiency and safety.

[0069] In some embodiments, Figure 1 As shown, the mobile battery-swapping vehicle 100 also includes a first vehicle controller 10 and a battery-swapping remote control 13 , and the battery-swapping device 12 , the first signal transceiver terminal 11 and the battery-swapping remote control 13 are all communicatively connected to the first vehicle controller 10 .

[0070] Specifically, the first vehicle controller 10, as the core control unit, is connected to the battery swap device 12, the first signal transceiver terminal 11 and the battery swap remote controller 13, and uniformly manages the data and instructions of each subsystem. The second vehicle controller 20 aggregates the information and distributes it to the battery swap device 12, the first signal transceiver terminal 11 and the battery swap remote controller 13, so as to realize the integrated control of the battery swap process of the mobile battery swap vehicle 100. The battery swap remote controller 13 allows the operator to remotely control the battery swap process on the mobile battery swap vehicle 100, which can improve the flexibility and safety of the battery swap operation.

[0071] Optionally, the mobile battery exchange vehicle 100 may also include mobile battery exchange vehicle sensors, motors and hydraulic valves, etc., and the first vehicle controller 10 is also communicatively connected to the mobile battery exchange vehicle sensors, motors and hydraulic valves.

[0072] The first vehicle controller 10 of this embodiment can achieve high integration and centralized management of the battery swapping system, thereby improving the operating efficiency and safety of the battery swapping system.

[0073] In some embodiments, the battery swap remote control 13 is configured to monitor the working status of the battery swap device 12 so as to control the mobile battery swap vehicle 100 through the first vehicle controller 10, and the battery swap remote control 13 is also configured to monitor the status information of the construction machinery 200 through the local area network so as to control the construction machinery 200 through the second vehicle controller 20. The status information of the construction machinery 200 includes at least one of the battery lock / unlock status, battery plug position, battery plug temperature and vehicle mode.

[0074] Specifically, by monitoring the battery lock / unlock status, when the battery to be replaced of the construction machinery 200 is in a locked state, the battery to be replaced is unlocked through the battery replacement remote control 13, and then the battery replacement device 12 performs battery replacement; when the battery to be replaced of the construction machinery 200 itself is in an unlocked state, the unlocking step of the battery replacement remote control 13 can be skipped.

[0075] Specifically, by monitoring the battery plug position, it is possible to know whether the power battery is installed in place; by monitoring the battery plug temperature, it is possible to know whether the power battery is supplying power normally. In the case of abnormal power supply, the battery plug temperature will rise abnormally; by monitoring the vehicle mode, it is possible to know whether the construction machinery is in operation mode or flameout and battery replacement mode. Battery replacement can only be performed when the construction machinery is in flameout and battery replacement mode.

[0076] This embodiment monitors the working status of the battery swapping device 12 and the status information of the engineering machinery 200 through the battery swapping remote control 13, and can simultaneously control the mobile battery swapping vehicle and the engineering machinery to complete the battery swapping through the local area network, which can improve the automation level and battery swapping efficiency of the battery swapping system.

[0077] In some embodiments, the battery-swapping remote controller 13 is configured to confirm the identification signal sent by the second signal transceiver terminal 21 to establish a network connection.

[0078] This embodiment confirms the identification signal through the battery replacement remote control 13, which can ensure stable communication between the battery replacement remote control 13 and the engineering machinery 200 and improve the reliability of the battery replacement system; the identification signal confirmation mechanism can ensure that only the engineering machinery 200 that needs battery replacement can establish a connection, prevent unauthorized access, and improve the security of the battery replacement system.

[0079] In some embodiments, Figure 2 As shown, the industrial computer 111 is communicatively connected to the first vehicle controller 10 , and the first signal transceiver terminal 11 also includes an antenna 113 .

[0080] Specifically, the antenna 113 is used to establish wireless communication with the engineering machinery 200, which can strengthen the signal and improve the stability of the wireless communication of the battery exchange system.

[0081] Secondly, if Figure 3 As shown, the present disclosure also proposes a battery replacement method based on the battery replacement system of the above embodiment, comprising:

[0082] The mobile battery swapping vehicle 100 and the construction machinery 200 are both transferred to the battery swapping position and switched to the battery swapping mode;

[0083] Make the wireless access point AP112 cooperate with the industrial computer 111 to complete the construction of the local area network;

[0084] The first signal transceiver terminal 11 and the second signal transceiver terminal 21 both receive and transmit wireless signals through the local area network.

[0085] The battery replacement method of this embodiment, by making the industrial computer 111 and the wireless access point AP112 cooperate to complete the construction of the local area network, can establish communication between the first signal transceiver terminal 11 and the second signal transceiver terminal 21 even in a tunnel environment without signals and without a unified control platform, and realize point-to-point or point-to-multipoint communication within the coverage of the local area network, thereby realizing centralized control of the battery replacement system, meeting the battery replacement needs of the construction machinery 200, and improving the automation level and efficiency of the battery replacement system.

[0086] In some embodiments, Figure 3 As shown, the mobile battery swapping vehicle 100 also includes a battery swapping remote controller 13, which enables the wireless access point AP112 to cooperate with the industrial computer 111 to complete the construction of the local area network, including:

[0087] The second signal transceiver terminal 21 sends an identification signal;

[0088] When the first signal transceiver terminal 11 receives the identification signal, the battery replacement remote control 13 is enabled to confirm to establish a network connection; when the first signal transceiver terminal 11 does not receive the identification signal, the second signal transceiver terminal 21 continues to send the identification signal.

[0089] The battery replacement method of this embodiment confirms the identification signal through the battery replacement remote control 13, which can ensure a stable network connection between the battery replacement remote control 13 and the engineering machinery 200, and improve the reliability of the battery replacement system; the identification signal confirmation can ensure that only the engineering machinery 200 that needs battery replacement can establish a connection, which can prevent unauthorized access and improve the security of the battery replacement system.

[0090] In some embodiments, Figure 3 As shown, the engineering machinery 200 also includes a battery replacement controller 22 and a battery box locking control mechanism 220. After the local area network is built, it also includes:

[0091] The battery replacement remote controller 13 sends an unlocking command to enable the battery box locking control mechanism 220 to unlock the battery to be replaced;

[0092] The battery exchange controller 22 is made to feedback the locking state. When the unlocking is completed, the battery exchange remote control 13 sends a battery exchange command to enable the mobile battery exchange vehicle 100 to replace the battery to be replaced of the construction machinery 200 with a spare battery; when the unlocking is not completed, the battery exchange remote control 13 continues to send the unlocking command.

[0093] The battery replacement method of this embodiment can avoid forced battery replacement when the battery is locked, prevent the battery replacement device 12 from causing damage to the construction machinery 200, and improve the safety of the battery replacement system by sending a battery replacement instruction when the battery to be replaced is unlocked.

[0094] In some embodiments, Figure 3 As shown, after the battery to be replaced is replaced with the spare battery, the following steps are also included:

[0095] When the spare battery is replaced, the battery replacement remote control 13 sends a locking command. When the spare battery is not replaced, the battery replacement remote control 13 resends the battery replacement command.

[0096] Optionally, whether the spare battery has been replaced can be determined by whether the battery plug is in the correct position, whether the battery plug temperature is normal, etc. For example, when the battery plug is in the correct position and the battery plug temperature is normal, it is determined that the spare battery has been replaced.

[0097] The battery replacement method of this embodiment can avoid repeated battery replacement operations due to battery failure after the battery is locked, or the spare battery cannot be locked due to structural interference, by sending a locking command when the spare battery is replaced. This can improve the battery replacement efficiency and safety of the battery replacement system.

[0098] In some embodiments, Figure 3 As shown, after the battery to be replaced is replaced with the spare battery, the following steps are also included:

[0099] When the spare battery is replaced, the battery replacement remote controller 13 sends a locking command to make the battery box locking control mechanism 220 lock the battery to be replaced;

[0100] The battery exchange controller 22 is made to feedback the locking status. When the locking is completed, the battery exchange remote control 13 is made to send a battery exchange end instruction; when the locking is not completed, the battery exchange remote control 13 continues to send a locking instruction.

[0101] The battery replacement method of this embodiment can prevent the battery from loosening during the operation of the engineering machinery 200 due to the backup battery not being locked by causing the battery replacement controller 22 to feedback the locking state, and can improve the safety of the engineering machinery 200 of the battery replacement system after the battery replacement.

[0102] In some embodiments, Figure 3 As shown, after completing the construction of the local area network, it also includes:

[0103] When the construction machinery 200 meets the battery replacement conditions, the mobile battery replacement vehicle 100 performs a battery replacement operation on the construction machinery 200. When the construction machinery 200 does not meet the battery replacement conditions, the construction machinery 200 and the mobile battery replacement vehicle 100 are readjusted.

[0104] Among them, the battery replacement conditions include at least one of the battery lock / unlock status, the battery plug is in the correct position, the battery plug temperature is normal, and the vehicle mode is normal.

[0105] Specifically, by monitoring the battery plug position, the battery replacement operation will not be performed when the power battery position is abnormal; by monitoring the battery plug temperature, the battery replacement operation will not be performed when the power supply of the power battery is abnormal; by monitoring the vehicle mode, the battery replacement operation will not be performed before the construction machinery is in the engine-off battery replacement mode.

[0106] The battery replacement method of this embodiment can improve the safety of the battery replacement system by ensuring that the battery replacement system can only replace batteries after the battery replacement conditions are met.

[0107] In some specific embodiments, the battery replacement method includes the following steps:

[0108] Step 1: When the construction machinery 200 is working in the tunnel, if the battery to be replaced is low on power, the mobile battery-changing vehicle 100 will transport a fully charged spare battery to the battery-changing location, and the operator will operate the mobile battery-changing vehicle 100 to prepare for the battery-changing;

[0109] Step 2. The second signal transceiver terminal 21 of the construction machinery 200 sends an identity authentication request through the WLAN local area network. After receiving the request, the first signal transceiver terminal 11 of the mobile battery swap vehicle 100 uploads the identity information to the first vehicle controller 10 and the battery swap remote control 13. After the battery swap remote control 13 confirms the identity, the authentication is completed and a wireless local area network is established.

[0110] Step 3: The battery swap controller 22 processes various information from the engineering machinery 200, including the battery box lock / unlock status, plug in place, plug temperature, and vehicle status, to determine whether the mobile battery swap vehicle 100 can perform a battery swap operation; if the battery swap operation conditions are met, the battery swap operation can be performed; otherwise, the engineering machinery 200 and the mobile battery swap vehicle 100 are readjusted;

[0111] Step 4: When the battery replacement operation conditions are met, the battery replacement remote controller 13 unlocks the battery to be replaced through the battery box locking control mechanism 220 and outputs a battery replacement start command;

[0112] Step 5, the battery replacement remote control 13 controls the battery replacement device 12 to replace the battery of the engineering machinery 200, and monitors the various states of the engineering machinery 200 after the battery replacement to determine whether the battery replacement is successful. If the battery replacement is unsuccessful, the battery replacement end command is re-issued.

[0113] Step 6: After the battery replacement is successful, the battery replacement remote control 13 locks the backup battery through the battery box locking control mechanism 220, outputs the battery replacement end command, disconnects the wireless LAN, and the mobile battery replacement vehicle 100 drives away from the battery replacement site.

[0114] Specifically, a WLAN local area network is established with the mobile battery exchange vehicle 100 through the second signal transceiver terminal 21, and the vehicle status information of the construction machinery 200 is transmitted to the mobile battery exchange vehicle 100 in real time. At the same time, the battery box locking control mechanism 220 accepts the centralized control of the battery exchange remote control 13 of the mobile battery exchange vehicle 100, unlocks the power battery, and starts to replace the battery. When the battery replacement is completed, the vehicle status information of the construction machinery 200 is transmitted to the mobile battery exchange vehicle 100 again. After confirming that the battery has been replaced, it accepts the centralized control of the battery exchange remote control 13 again. The battery box locking mechanism will lock the power battery, disconnect the WLAN local area network, and the battery replacement work is completed. By realizing information interaction throughout the battery replacement process, which is centrally controlled by the battery replacement remote control 13 of the mobile battery exchange vehicle 100, the battery replacement efficiency can be greatly improved.
