[0053] The method embodiment provided in this embodiment can be executed in a terminal, a computer or a similar computing device. For example, running on a terminal, Figure 1 FIG. 1 is a hardware structure diagram of a terminal of the battery information display method of this embodiment. Figure 1 As shown, the terminal may include one or more ( Figure 1 Only one is shown in the figure) processor 102 and memory 104 for storing data, wherein processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA. The above terminal may also include a transmission device 106 and an input and output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0054] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the battery information display method in the present embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the above method is implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories can be connected to the terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof.

[0055] The transmission device 106 is used to receive or send data via a network. The above network includes a wireless network provided by the communication provider of the terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0056] In this embodiment, a battery information display method is provided. Figure 2 is a flow chart of the battery information display method of this embodiment. Figure 2 As shown, the process includes the following steps:

[0057] Step S210, in response to the user entering a preset operation area of ​​the display and control terminal, a preset main interface is displayed.

[0058] Specifically, the battery information display method can be applied to a display and control terminal, which can be a terminal device with data processing capabilities and a display and control screen. The display and control terminal can be connected to the battery management system (BMS) of the energy storage battery through wired communication or wireless communication to achieve data interaction. Among them, wired communication includes controller area network (Controller Area Network, referred to as CAN), serial communication protocol RS-485 and other methods; wireless communication includes Bluetooth, Wi-Fi and other methods. The display and control terminal can display the battery information on the display and control screen in real time through communication with the BMS, and based on the interaction with the user, send the user's control instructions to the BMS. The BMS operates the control instructions according to the current status of the energy storage battery, and transmits the operation results back to the display and control screen of the display and control terminal.

[0059] Figure 3 FIG. 1 is a schematic diagram of a display and control screen of a display and control terminal of this embodiment. Figure 3 As shown, the display control screen includes a display control interface 301, an outer frame 302, an infrared sensor 303 and a camera 304. Among them, the camera 304 can be used for personnel identification and permission granting. The infrared sensor 303 can be used to identify personnel operations and perform energy-saving algorithms. The display control interface 301 can be specifically a touch display area for displaying battery information and issuing and feedback of control instructions. The outer frame 302 is used to support and fix the display control screen.

[0060] The infrared sensor 303 and the camera 304 can be arranged on the outer frame. The infrared detection range of the infrared sensor 303 and the image acquisition range of the camera 304 need to cover the required detection area in front of the display and control terminal. This embodiment does not limit the specific setting positions of the infrared sensor 303 and the camera 304. In addition, the screen of the display and control terminal can be a touch screen.

[0061] In particular, it is possible to determine that the user has entered the preset operation area of ​​the display and control terminal based on the detection of the infrared sensor, the camera, or the user's touch operation on the display and control screen of the display and control terminal. The preset operation area may be an area where the user stands in front of the display and control terminal to interact with the interface. When the display and control terminal is not operated for a long time and no operator is detected, the screen of the display and control terminal will enter a low-power screen-off mode. In the screen-off mode, the infrared sensor and touch components can operate normally, other components enter a dormant state, and the display components of the screen have no display.

[0062] When it is detected that the user enters the preset operation area of ​​the display and control terminal, the display and control terminal will automatically light up the screen from the screen-off mode to the normal display mode, display the preset main interface, and communicate with the BMS in real time to update the battery information to be displayed.

[0063] Step S220, in response to the user's permission login operation on the main interface, displaying a battery information interface corresponding to the user permission of the currently logged-in user; wherein different levels of user permissions correspond to different battery information interfaces.

[0064] Among them, the battery information interface corresponding to the user authority of the currently logged-in user is displayed. It can be that a battery information interface with different implementation contents is presented according to different user authorities; or, according to different user authorities, operation permissions are opened for different function buttons in the battery information interface.

[0065] User rights can be divided into more than one level according to customer needs in actual application scenarios. For example, taking the user rights divided into three levels as an example: the first level user right is to view battery information; the second level right is the basic control right, such as the control right of powering on and off the battery management system; the third level right is the higher-level control right, such as parameter configuration right. In addition, more or fewer levels of rights can also be set according to customer needs, and the specific content corresponding to each level of rights can also be determined according to the actual application scenario, which is not specifically limited in this embodiment.

[0066] In addition, the user's permission login operation on the main interface can be specifically initiated by the user clicking a preset login button on the main interface. Afterwards, the display and control terminal responds to the user's permission login operation and displays the corresponding battery information interface based on the user's logged-in account.

[0067] The following is an example to illustrate. Figure 4 is a schematic diagram of a main interface of this embodiment, such as Figure 4 As shown, the main interface may include a general control data viewing button 401, an alarm viewing button 402, a parameter setting button 403, a master control data viewing button 404, a system control button 405, and a system management button 406. Among them, some buttons require logging in with the corresponding user authority to operate. For example, a user with level one authority can only use the information viewing functions of the master control data, general control data, alarm viewing and other buttons on the interface; a user with level two authority can use the system control function on the basis of being able to use the functions corresponding to the level one authority; a user with level three authority can use the parameter setting function on the basis of being able to use the functions corresponding to the level one and level two authorities. When the user is in Figure 4 Clicking the system management button 406 on the main interface can be regarded as initiating a permission login operation, and then the user can be redirected to the user management interface to log in with different levels of permissions.

[0068] Figure 5 FIG. 1 is a schematic diagram of a user management interface of this embodiment. Figure 5As shown, the user management interface includes a second-level permission login button, a second-level permission logout button, a second-level permission password modification button, a third-level permission login button, a third-level permission logout button, and a third-level permission password modification button. Users can manage different user permissions in the user management interface, log in, log out, modify passwords, and other operations for second-level and third-level permissions. Among them, after the second-level permission is logged out, the second-level permission operation can no longer be performed. If the third-level permission operation can be performed before logout, the third-level permission operation can no longer be performed after logout. The first-level permission can still be operated normally. After the third-level permission is logged out, the third-level permission operation can no longer be performed, and the first-level permission is not affected. If the second-level permission is not logged in before the third-level permission is logged in, then after the third-level permission is logged out, the second-level permission is logged out at the same time; if the second-level permission is logged in before the third-level permission is logged in, then after the third-level permission is logged out, the second-level permission can still be operated. Exemplarily, when the user clicks Figure 5 Click the secondary permission login button to execute the permission login operation and jump to the secondary permission login interface. Figure 5 It can also display which category the current user belongs to, for example, whether the current user is a common user or an administrator.

[0069] The user login permissions are realized by the user account and password generated by the backend. Among them, the second-level permissions and third-level permissions are distinguished by account, password and other information. Restrictions will be set for the same account and password but different permissions, that is, the same account and password can only correspond to one permission. The account and password corresponding to each permission will be released to the user for use.

[0070] Figure 6 This is a schematic diagram of a permission login interface of this embodiment, such as Figure 6 As shown, the permission login interface may include a secondary permission login dialog box 601, in which the user can enter the account and password corresponding to the secondary permission and click the OK button to log in. In addition, the permission login interface is also configured with a secondary permission login button and a tertiary permission login button to trigger the corresponding permission login. When the user clicks the return button of the permission login interface, it can return to Figure 5 The user management interface shown in the figure. In the case where the operator authentication is not enabled, the permission login dialog box may display the prompt "Operator authentication is not enabled".

[0071] In related technologies, the display and control screen is often based on the interaction with the BMS to display the real-time data and status of the battery. The current display and control screen has poor human-computer interaction, cannot implement corresponding authority management according to different users, and the system automation efficiency is low.

[0072] This embodiment performs multi-level permission settings to match different user authorizations. Different display interfaces are displayed according to the different permissions of the user's login, thereby realizing different permission management and control according to the needs of different levels of user groups, realizing the diversification of permission management and improving the effect of interpersonal interaction.

[0073] In the above steps S210 to S220, in response to the user entering the preset operation area of ​​the display and control terminal, the preset main interface is displayed; in response to the user's permission login operation on the main interface, the battery information interface corresponding to the user authority of the currently logged-in user is displayed; wherein, different levels of user authority correspond to different battery information interfaces. It can provide different authority management for different users, thereby realizing the diversification of battery information authority management.

[0074] In one embodiment, in response to the user's permission login operation on the main interface, displaying a battery information interface corresponding to the user permission of the currently logged-in user may include:

[0075] When the user turns on the preset operator authentication, in response to the user's permission login operation on the main interface, the user's identification result is obtained based on account verification and biometric recognition; the identification result is compared with the preset reference information library to determine the user's login authority; if the login authority determination is passed, the battery information interface corresponding to the user authority of the currently logged-in user is displayed.

[0076] Among them, you can set a button to enable operator authentication on the permission login interface. Figure 6 The right side of the dialog box 601 also includes a button for applying for a second-level authority operator and a button for applying for a third-level authority operator. When the user clicks the button for applying for a second-level authority operator, the operator authentication corresponding to the second-level authority can be enabled; when the user clicks the button for applying for a third-level authority operator, the operator authentication corresponding to the third-level authority can be enabled. Figure 5 The user management interface can also set corresponding buttons for second-level authority operators to apply and third-level authority operators to apply.

[0077] When the operator authentication function is not enabled, the user can directly log in to the corresponding authority by entering the corresponding account and password in the authority login interface. After the operator authentication function is enabled, the account password and the operator's biometric identification must be met at the same time, and the identification result must be compared with the preset reference information library. Only after the comparison is passed can the corresponding authority be logged in. Among them, the biometric feature can include one or more of facial features, fingerprint features, and retinal features. The reference information library can be a pre-stored white list, which can store the facial features, fingerprint features, and retinal features of users with login permissions. For example, after the account is verified, the user's face can be recognized, and the recognized facial features can be compared with the white list to determine whether the user has login permissions; or the user's fingerprint or retinal recognition can be performed, and the recognized fingerprint features or retinal features can be compared with the white list to determine whether the user has login permissions. In addition, facial recognition, fingerprint recognition, and retinal recognition can also be combined, combined with a preset white list to determine whether the user has login permissions.

[0078] Figure 7 This is another schematic diagram of a permission login interface of this embodiment, such as Figure 7 As shown, in Figure 6 On the basis of this, a text prompt "Operator authentication has been enabled. Enter face recognition after successful account verification" is also set inside dialog box 601. First, the user enters the account and password in the permission login interface for preliminary verification. After the account and password are verified successfully, the display and control terminal will turn on the camera to perform face recognition on the user. The recognized face information is compared with the local reference data (pre-entered white list) or the reference data in the cloud through the BMS. After the comparison with the reference data is successful, the display and control terminal will enable permissions to enable the user to perform operations corresponding to the permission on the display and control interface. It can be understood that except Figure 7 In addition to the identification methods shown, the display and control terminal can also integrate a fingerprint collection device to perform fingerprint identification on the user, and integrate a retinal identification device to perform retinal identification on the user, which is not specifically limited in this embodiment.

[0079] Understandably, according to the needs of the actual application scenario, when the operator authentication is turned on, the permission login interface can be set to not require a password, and face, fingerprint or retina recognition can be performed directly to determine whether to release the permission. In addition, in the operator application process, taking face recognition as an example, before turning on the operator authentication, an operator application is required. When the operator applies, the account is verified first. After the verification is successful, face recognition is entered. The face information is compared with the local whitelist or the cloud whitelist. If the comparison is successful, the operator authentication can be turned on. The whitelist can be entered in advance after review during the operation training, technical assessment and other processes. Finally, after the permission login is successful, the corresponding permission and lower-level permission operations can be performed. Figure 8 This is another schematic diagram of the permission login interface of this embodiment. Figure 8 As shown, dialog box 801 is a dialog box for applying for a third-level permission operator. After the user enters the account and password in dialog box 801 and clicks the OK button for verification, the operator authentication can be started. Similarly, a second-level permission login button, a third-level permission login button, a second-level permission operator application button, and a third-level permission operator application button can also be set on both sides of dialog box 801. The user clicks the corresponding button to jump into the corresponding operation interface. The user clicks Figure 8 The return button can return to the permission login interface or user management interface. Figure 8 The dialog box 801 may also display a prompt message “Enter face recognition after successful account verification”.

[0080] Specifically, when verifying the account and password, the account and password can be verified locally or in the cloud. When verifying locally, the account and password entered by the user are compared with the data stored locally in the BMS, and the corresponding permissions can be granted after the comparison is successful.

[0081] When verifying in the cloud, the user needs to send the account and password to the cloud remotely through the BMS, which will be compared with the cloud data and then fed back to the BMS, which will release the final usage rights. In addition, dual databases in the cloud and the BMS can be used for combined verification, that is, the local verification can release the rights if it succeeds, and the cloud verification will release the rights if it succeeds after the local verification fails.

[0082] In addition, for the operator's identity verification, it can also be verified by comparing the whitelist locally and in the cloud. In particular, considering the real-time requirements for data updates and the large amount of data, cloud verification is preferred. In the verification process, both automatic algorithm verification and manual verification can be used, or automatic verification can be used as the main method with manual verification as the auxiliary method.

[0083] In this embodiment, when the user turns on the preset operator authentication, the user's login authority is determined by combining account verification and biometric recognition, which can improve the security of authority release. In addition, based on the real-time authority management of the cloud platform, account release and recovery are performed through the cloud platform, and remote authority management is performed, which can also meet the real-time needs of data and authority management in the case of large data volume.

[0084] Additionally, in one embodiment, the battery information display method may further include:

[0085] When the user authority of the currently logged-in user is the lowest level authority and the current operating status meets the preset screen-off conditions, the control display screen enters the screen-off state; when the user authority of the currently logged-in user is other levels of authority above the lowest level authority and the current operating status meets the preset authority downgrade conditions, the control display screen displays the battery information interface corresponding to the authority downgrade.

[0086] Specifically, when the user authority of the currently logged-in user is the lowest level authority, such as the first level authority mentioned above, if an operator is detected but no one operates for a first period of time, it is determined that the current operation state meets the screen-off condition, and the display control screen is controlled to enter the screen-off state. Alternatively, if no operator is detected and no one operates for a second period of time, the screen-off state is automatically entered. The first period of time mentioned above is greater than the second period of time. In the screen-off state, only the infrared sensor and the touch component operate, and other components enter the sleep mode.

[0087] When the user rights of the currently logged-in user are higher than the lowest level (such as the second or third level mentioned above), the display screen periodically detects whether the operator is present. If the background algorithm recognizes that the operator is missing based on the detection cycle and the number of detection points, the user rights of the currently logged-in user are adjusted to the lowest level, and the corresponding battery information interface after the downgrade is displayed. After the rights are downgraded, you need to log in again to operate the functions corresponding to the high-level rights.

[0088] In particular, in some of the embodiments, if the operator authentication mode is turned on, the display and control screen periodically detects the existence of the logged-in operator. If the background algorithm recognizes that the logged-in person has disappeared based on the detection cycle and the number of detection points, the authority is automatically reduced to the first-level authority. If the logged-in operator exists but has not performed any operation for a fourth time period, the authority is also automatically reduced to the first-level authority. In this case, after the authority is reduced, you need to log in again to operate the functions corresponding to the advanced authority.

[0089] This embodiment detects the current operating state and controls the display control screen to enter the screen-off state according to the detection result, so as to achieve low-power operation and reduce power consumption. According to the current operating state, the higher-level user rights are downgraded to ensure the security of system operation.

[0090] In one embodiment, a first detection result of whether the display screen is unmanned is obtained based on real-time screen touch detection; a second detection result of whether there is an operator is determined based on infrared detection; and the current operation status is determined based on the first detection result and the second detection result.

[0091] Under normal conditions, the display screen will detect the input of the touch component in real time. The background algorithm of the display device will evaluate whether no input information is recognized based on the touch detection cycle and the number of touch detection points of the touch component. If so, it is considered that there is no operator. When the display screen is working, the infrared sensor will detect infrared signals in real time. The background algorithm will evaluate whether no infrared sensing information is recognized based on the infrared detection cycle and the number of infrared detection points. If so, it is considered that there is no operator.

[0092] In the off-screen state, the infrared sensor works normally. When it senses the infrared signal and identifies a person, the screen automatically lights up and enters the main interface. The screen starts to work normally and communicates with the BMS in real time to update the battery data. In addition, in the off-screen state, touching the touch area of ​​the display screen will also automatically light up and enter the main interface.

[0093] In this embodiment, infrared detection is combined with screen touch detection to confirm the current operating state of the display and control screen, thereby improving the accuracy of current operating state detection.

[0094] In addition, in one embodiment, before displaying a preset main interface in response to the user entering a preset operation area of ​​the display and control terminal, the battery information display method may further include:

[0095] When an infrared signal in a preset operation area is detected by the infrared sensor, it is determined that there is an active target in the operation area, and image information in the operation area is collected by the image sensor; the image information is processed by the portrait recognition algorithm to determine whether the active target is a user.

[0096] That is, when the screen is off, if the infrared sensor detects an infrared signal in the preset operation area, it is considered that there is an active target in the operation area. The camera then periodically obtains the surrounding image information and uses the portrait recognition algorithm to identify whether the infrared signal source (active target) is a human body and determines whether it is a user.

[0097] This embodiment combines infrared detection with image detection to achieve image detection triggering in low power consumption mode, avoiding the camera from performing real-time image detection for a long time, thereby achieving low power consumption and accurate portrait recognition.

[0098] In one embodiment, before displaying a preset main interface in response to a user entering a preset operation area of ​​the display and control terminal, the battery information display method may further include:

[0099] When a screen touch operation is detected, it is determined that there is an active target in the operation area, and image information in the operation area is collected through an image sensor; the image information is processed through a portrait recognition algorithm to determine whether the active target is a user.

[0100] The display screen is equipped with a touch component. When the user touches the touch area of ​​the display screen, the touch component will detect the screen touch operation. At this time, it is confirmed that there is an active target in the operation area. Similarly, the display screen automatically lights up, and the camera collects image information in the operation area. Through portrait recognition and face recognition, it is determined whether the active target is the user.

[0101] This embodiment combines screen touch detection and image detection, and can also realize image detection triggering in low power consumption mode, avoiding the camera from performing real-time image detection for a long time, thereby realizing low-power consumption and accurate portrait recognition.

[0102] Optionally, in one embodiment, based on the above step S220, in response to the user's permission login operation on the main interface, displaying a battery information interface corresponding to the user permission of the currently logged-in user may include:

[0103] In response to the user with the lowest user authority level, the permission login operation on the main interface opens the battery information viewing permission corresponding to the lowest level user authority in the battery information interface; in response to the user with an intermediate user authority level, the permission login operation on the main interface opens the battery management system control permission corresponding to the intermediate user authority in the battery information interface; in response to the user with the highest user authority level, the permission login operation on the main interface opens the parameter configuration permission corresponding to the highest level user authority in the battery information interface.

[0104] For example, if the current login authority level is level one, the operation authority for viewing battery information is opened on the interface; if the current login authority level is level two, the control authority for the battery management system is opened on the interface; if the current login authority level is level three, the parameter configuration authority is opened on the interface.

[0105] This embodiment performs multi-level permission setting to match different user authorizations, thereby achieving diversified permission management and control.

[0106] Fig. 9 is a flowchart of a battery information display method in some embodiments, such as Fig. 9 As shown, the battery information display method includes the following steps:

[0107] Step S901, in the screen-off state, when the infrared sensor detects an infrared signal in a preset operation area, and / or when the touch component detects a screen touch operation, it is determined that there is an active target in the operation area.

[0108] Step S902: collecting image information in the operation area through an image sensor.

[0109] Step S903: Process the image information through a portrait recognition algorithm to determine whether the activity target is a user.

[0110] Step S904: in response to the user entering the preset operation area of ​​the display and control terminal, displaying a preset main interface.

[0111] Step S905, in response to the user's permission login operation on the main interface, display the battery information interface corresponding to the user authority of the currently logged-in user; wherein, when the user turns on the preset operator authentication, in response to the user's permission login operation on the main interface, the user's login authority is determined based on account verification and biometric recognition; when the login authority determination is passed, the battery information interface corresponding to the user authority of the currently logged-in user is displayed.

[0112] The above steps S901 to S905 can provide different authority management for different users, thereby realizing the diversification of battery information authority management.
