Description

Technical Field

[0001] This invention relates to the field of battery control, and more specifically to a battery start-stop control system for vehicles. Background Technology

[0002] Transportation is an indispensable part of modern life. With the changes of the times and the progress of science and technology, there are more and more means of transportation around people, including cars, electric vehicles, bicycles, airplanes and ships, which have greatly shortened the distance between countries and between people, making people's travel more convenient.

[0003] With the widespread use of transportation vehicles and the development of electric vehicle technology, people are using electric vehicles more and more in their daily lives. As a result, electric vehicle safety management has become one of the focuses of attention. The battery of an electric vehicle is the core component of the entire electric vehicle. Abnormal conditions of the power battery may lead to serious accidents such as fires and explosions. In order to ensure the safety of the public and the environment, the supervision of electric vehicle batteries has become a necessity for social safety management.

[0004] However, in real life, users of electric vehicles often use accessible elevators or freight elevators to transport their vehicles to upper floors for charging. Due to the safety hazards of electric vehicle batteries, such as fire, overheating, and damage, the safety of elevator use is reduced, increasing the risk of electric vehicle accidents. Based on this, a battery start-stop control system for transportation vehicles is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a battery start-stop control system for transportation vehicles, which solves the technical problem that in real life, users of electric vehicles need to use accessible elevators or freight elevators to transport their electric vehicles to upper floors for charging, which reduces the safety of elevator use and increases the risk of electric vehicle safety accidents.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A battery start-stop control system for a vehicle includes:

[0008] The restricted area generation module is used to obtain the elevator location and draw a circle with the center of the elevator as the center and R1 as the radius to generate the restricted area corresponding to the elevator. At the same time, the restricted area is sent to the spacing distance value acquisition module, where R1 is a preset value. Meanwhile, electronic fence devices are set up around the restricted area and connected to the monitoring platform.

[0009] The positioning acquisition module uses GPS positioning technology to locate the vehicle's position, acquires the vehicle's location information, and sends it to the distance value acquisition module.

[0010] The spacing distance value acquisition module is used to acquire the location information of the electric vehicle and the distance between the electric vehicle and the center of the restricted area, and mark it as the spacing distance value. At the same time, the spacing distance value is sent to the warning signal generation module. The specific method of acquiring the spacing distance value is: to acquire the minimum distance between the electric vehicle and the center of the restricted area and mark it as the spacing distance value L1.

[0011] The warning signal generation module compares the distance value with the preset value, generates warning signals of different levels based on the judgment result, and sends them to the control command generation module.

[0012] The vertical height value acquisition module is used to acquire the vertical height value between the electric vehicle and the ground and send it to the warning signal generation module;

[0013] The control command generation module is used to acquire warning signals of different levels, generate different control commands based on the different levels of warning signals, and send them to the control module.

[0014] The control module is used to acquire different control commands and perform corresponding control operations on the electric vehicle according to the different control commands.

[0015] As a further aspect of the present invention, the specific method for generating warning signals of different levels is as follows:

[0016] S1: When the distance value L1 satisfies L1≥Y1 and G≤Y2, a first-level warning signal is generated; when L1≥Y1 and G>Y2, no action is taken.

[0017] S2: When L1 < Y1 and G ≤ Y2, a level 2 warning signal is generated;

[0018] S3: When L1 < Y1 and G > Y2, a level 3 warning signal is generated, where G is the vertical height of the electric vehicle from the ground, Y1 is the distance threshold, and Y2 is the height threshold.

[0019] As a further aspect of the present invention, the specific method for obtaining the vertical height value G is as follows:

[0020] An altitude sensor is installed on the electric vehicle to acquire the vertical height value G of the electric vehicle from the ground, and the real-time acquired vertical height value is sent to the warning signal generation module.

[0021] As a further aspect of the present invention, the specific method for generating different control commands is as follows:

[0022] When a Level 1 warning signal is received, an alarm control command is generated; when a Level 2 warning signal is received, a power-off control command is generated; and when a Level 3 warning signal is received, a charging input port shutdown control command is generated.

[0023] As a further aspect of the present invention, the specific method for performing corresponding control operations on the electric vehicle according to different control commands is as follows:

[0024] When an alarm control command is received, the controller controls the alarm device to sound an alarm; when a power-off control command is received, the controller can turn off the power to the electric vehicle by controlling the power switch; when a charging input port closing control command is received, the controller sends a command to the electric vehicle to make the electric vehicle close the charging input port.

[0025] As a further aspect of the present invention, it also includes a violation signal generation module;

[0026] The violation signal generation module is used to obtain the number of different levels of warning signals generated by the elevator within a time range T from the warning signal generation module, analyze the number of warning signals of different levels, obtain the violation value of the elevator based on the analysis results, analyze and determine the violation value to generate a violation signal, and finally send the generated violation signal to the display module for display. The specific method for generating the violation signal is as follows:

[0027] The number of Level 1, Level 2, and Level 3 warning signals generated within the time range T are labeled as K1, K2, and K3, respectively. The violation value corresponding to the elevator is calculated using the formula K1×β1+K2×β2+K3×β3=M, where β1, β2, and β3 are preset values. When M≤Y3, no action is taken; when M>Y3, a violation signal is generated, where Y3 is a preset value.

[0028] As a further aspect of the present invention, it also includes an over-violation period marking module;

[0029] The excessive violation period marking module is used to acquire and analyze the number of different levels of warning signals generated by the elevator at different times within the time range T after the elevator generates a violation signal. Based on the analysis results, the corresponding time period is marked as an excessive violation period. At the same time, the excessive violation period is bound to the corresponding elevator and output to the display module. The method for marking the corresponding time period as an excessive violation period is as follows:

[0030] Obtain the number of different levels of warning signals generated in different time periods within the time range T. Divide the day into 24 equal time periods. Obtain the average of the first-level warning signals, second-level warning signals, and third-level warning signals generated in each time period within the time range T and label them as K4j, K5j, and K6j, respectively. Here, j refers to the corresponding time period number, j = {1, 2, ..., 24}.

[0031] The violation index Hj for each time period is calculated using the formula K4j×β4+K5j×β5+K6j×β6=Hj, where β4, β5, and β6 are preset values, and β4+β5+β6=1, β6>β5>β4. The time periods corresponding to Hj>Y4 are marked as excessive violation time periods, while the time periods corresponding to Hj≤Y4 are not processed, where Y4 is a preset value.

[0032] As a further aspect of the present invention: a display module is used to display violation signals and periods exceeding the violation threshold, along with the corresponding elevators.

[0033] The beneficial effects of this invention are:

[0034] (1) This invention obtains the elevator location, generates a restricted area corresponding to the elevator by combining it with an electronic fence, monitors and obtains the distance value between the electric vehicle and the restricted area, compares the distance value with a preset value to generate different control commands, and then controls the alarm device to issue an alarm, turn off the power of the electric vehicle or turn off the charging input port according to the different control commands, so as to realize the control and safety warning of the electric vehicle, and realize the control and safety warning of the electric vehicle going upstairs, so as to improve the safety of elevator use, reduce the risk of accidents, and reduce the possibility of violations and accidents.

[0035] (2) This invention analyzes the number of different levels of warning signals generated by the elevator and generates violation signals based on the analysis results. The violation signals remind relevant personnel to take corresponding measures in a timely manner to strengthen the control of electric vehicles illegally going upstairs within the elevator range, so as to improve the safety of elevator use and reduce the risk of accidents.

[0036] (3) This invention acquires and analyzes the number of different levels of warning signals generated by the elevator at different times within the time range T. Based on the analysis results, the corresponding time period is marked as the violation period. At the same time, the violation period is bound to the corresponding elevator and output to the display module. The violation period of the corresponding elevator is displayed through the display module. This is conducive to relevant personnel strengthening supervision of the elevator or taking targeted measures during the time period corresponding to the violation period, and strengthening the control of the illegal upstairs behavior of electric vehicles within the range of the elevator.

[0037] The invention will now be further described with reference to the accompanying drawings.

[0038] Figure 1 This is a schematic diagram of the framework structure of a battery start-stop control system for a transportation vehicle according to the present invention. Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] Please see Figure 1 As shown, the present invention is a battery start-stop control system for a vehicle, including a restricted area generation module, a distance value acquisition module, a positioning acquisition module, a warning signal generation module, a control command generation module, a vertical height value acquisition module, a control module, a violation signal generation module, an over-violation period marking module, and a display module;

[0042] The restricted area generation module is used to obtain the elevator's location and draw a circle with the elevator's center as the center and R1 as the radius to generate the restricted area corresponding to the elevator. At the same time, the restricted area is sent to the spacing distance value acquisition module. Here, R1 is a preset value, and the specific value is determined by relevant staff based on experience.

[0043] At the same time, electronic fence devices are set up around the restricted area and connected to the monitoring platform. The electronic fence devices can detect electric vehicles to monitor their location changes and violations in real time. The electronic fence devices can be virtual fences or physical devices, such as sensors or cameras, to ensure that the effective coverage of the electronic fence devices includes the boundary of the restricted area.

[0044] The positioning acquisition module uses GPS positioning technology to locate the vehicle's position, acquires the vehicle's location information, and sends it to the distance value acquisition module.

[0045] The distance acquisition module is used to acquire the location information of the electric vehicle and the distance between the electric vehicle and the center of the restricted area, marking it as the distance value. Simultaneously, the distance value is sent to the warning signal generation module. The specific method for acquiring the distance value is as follows:

[0046] Obtain the minimum distance between the electric vehicle and the center of the restricted area, and mark it as the spacing distance value L1;

[0047] The warning signal generation module compares the distance value with a preset value, generates warning signals of different levels based on the judgment result, and sends them to the control command generation module. The specific method for generating warning signals of different levels is as follows:

[0048] S1: When the distance value L1 satisfies L1≥Y1 and G≤Y2, a first-level warning signal is generated; when L1≥Y1 and G>Y2, no action is taken.

[0049] S2: When L1 < Y1 and G ≤ Y2, a level 2 warning signal is generated;

[0050] S3: When L1 < Y1 and G > Y2, a level 3 warning signal is generated, where G is the vertical height between the electric vehicle and the ground, Y1 is the distance threshold, and Y2 is the height threshold. The specific values ​​are determined by relevant staff based on experience.

[0051] The vertical height value acquisition module is used to acquire the vertical height value between the electric vehicle and the ground, and send it to the warning signal generation module. The specific method for acquiring the vertical height value G is as follows:

[0052] An altitude sensor is installed on the electric vehicle to acquire the vertical height G of the electric vehicle from the ground. The real-time vertical height value is then sent to the warning signal generation module. Radar, ultrasonic waves, or other sensors can also be used to measure the vertical height of the electric vehicle from the ground to ensure the accuracy and reliability of the sensor.

[0053] The control command generation module is used to acquire warning signals of different levels, generate different control commands based on the different levels of warning signals, and send them to the control module. The specific method for generating different control commands is as follows:

[0054] When a Level 1 warning signal is received, an alarm control command is generated; when a Level 2 warning signal is received, a power-off control command is generated; when a Level 3 warning signal is received, a charging input port shutdown control command is generated.

[0055] The control module is used to acquire different control commands and perform corresponding control operations on the electric vehicle based on these commands. The specific control operations are as follows:

[0056] When an alarm control command is received, the controller controls the alarm device to sound an alarm, reminding electric vehicle users to prohibit electric vehicles from entering the area. The alarm device can convey the alarm to electric vehicle users by emitting sound and light, thus serving as a warning to them.

[0057] When a power-off control command is received, the controller can shut off the power to the electric vehicle by controlling the power switch, cutting off the battery's power supply to the electric vehicle and causing it to lose power, thereby preventing the electric vehicle from entering the elevator.

[0058] When the controller receives a charging input port closing control command, it sends a command to the electric vehicle to close the charging input port, preventing the electric vehicle battery from receiving charging input and prohibiting the charging operation of the electric vehicle.

[0059] By acquiring the elevator's location and combining it with an electronic fence to generate a restricted area corresponding to the elevator, the distance between the electric vehicle and the restricted area is monitored and acquired. The distance value is compared with a preset value to generate different control commands. Based on the different control commands, the controller controls the alarm device to issue an alarm, shut down the electric vehicle's power, or close the charging input port. This achieves the management and safety warning of electric vehicles, improves the safety of elevator use, reduces the risk of accidents, and minimizes the possibility of violations and accidents.

[0060] Example 2

[0061] As a second embodiment of the present invention, in specific implementation, compared with the first embodiment, the technical solution of this embodiment differs from that of the first embodiment only in that this embodiment further includes a violation signal generation module, used to obtain the number of different levels of warning signals generated by the elevator within the time range T from the warning signal generation module, analyze the number of warning signals of different levels, obtain the violation value of the elevator based on the analysis results, then analyze and determine the violation value to generate a violation signal, and finally send the generated violation signal to the display module for display. The specific method for generating the violation signal is as follows:

[0062] The time range T refers to the time range of 60 days from the current time, excluding the data on the day the data was acquired;

[0063] The number of Level 1, Level 2, and Level 3 early warning signals generated within the time range T are labeled as K1, K2, and K3, respectively.

[0064] The violation value corresponding to the elevator is calculated using the formula K1×β1+K2×β2+K3×β3=M, where β1, β2 and β3 are preset values, and the specific values ​​are determined by relevant staff based on experience.

[0065] When M≤Y3, no action is taken; when M>Y3, a violation signal is generated, where Y3 is a preset value, and the specific value is determined by relevant staff based on experience.

[0066] The larger the value M of the violation, the more electric vehicles illegally go upstairs within the elevator's range, and the more serious the safety hazard.

[0067] The violation signal is displayed through the display module so that relevant personnel can be alerted in time and take corresponding measures to strengthen the control of electric vehicles going upstairs in violation of regulations within the elevator area;

[0068] By analyzing the number of different levels of warning signals generated by the elevator, and generating violation signals based on the analysis results, relevant personnel are reminded to take appropriate measures to address the elevator issue in a timely manner. This strengthens the control over the illegal upstairs behavior of electric vehicles within the elevator's coverage area, thereby improving elevator safety and reducing the risk of accidents.

[0069] Example 3

[0070] As a third embodiment of the present invention, in specific implementation, compared with embodiments one and two, the only difference between the technical solution of this embodiment and embodiments one and two is that this embodiment includes an over-violation period marking module. This module is used to acquire and analyze the number of different levels of warning signals generated by the elevator at different times within the time range T after the elevator generates a violation signal, and to mark the corresponding time period as an over-violation period based on the analysis results. Simultaneously, the over-violation period is bound to the corresponding elevator and output to the display module. The method for marking the corresponding time period as an over-violation period is as follows:

[0071] Obtain the number of different levels of warning signals generated in different time periods within the time range T. Divide the day into 24 equal time periods. Obtain the average of the first-level warning signals, second-level warning signals, and third-level warning signals generated in each time period within the time range T and label them as K4j, K5j, and K6j, respectively. Here, j refers to the corresponding time period number, j = {1, 2, ..., 24}.

[0072] The violation index Hj for each time period is calculated using the formula K4j×β4+K5j×β5+K6j×β6=Hj, where β4, β5 and β6 are preset values, and β4+β5+β6=1, β6>β5>β4. The specific values ​​are determined by relevant staff based on experience.

[0073] The time periods corresponding to Hj > Y4 are marked as exceeding the violation period, and the time periods corresponding to Hj ≤ Y4 are not processed. Here, Y4 is a preset value, and the specific value is determined by relevant staff based on experience.

[0074] After the elevator generates a violation signal, the number of different levels of warning signals generated by the elevator at different times within the time range T is obtained and analyzed from the warning signal generation module. Based on the analysis results, the corresponding time period is marked as the violation period. At the same time, the violation period is bound to the corresponding elevator and output to the display module. The display module displays the violation period of the corresponding elevator, which helps relevant personnel to strengthen the supervision of the elevator or take targeted measures during the violation period, and strengthen the control of the illegal upstairs behavior of electric vehicles within the area of ​​the elevator.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
