[0047] The embodiment of the present application discloses a monitoring and management system for electric vehicles with 4G communication function.

[0048] Reference Figure 1 A monitoring and management system for electric vehicles with 4G communication function includes an intelligent control device 1, a background server 2, a 4G communication module 3 and a handheld terminal 4. The signal output end of the intelligent control device 1 is coupled with the 4G communication module 3 so that the intelligent control device 1 has the function of sending and receiving signals. The background server 2 is wirelessly connected to the 4G communication module 3, and the background server 2 is connected to the handheld terminal 4 through the network, wherein the handheld terminal 4 is a mobile phone.

[0049] Reference Figure 1 and Figure 2, the intelligent control device 1 is the central control of the electric vehicle, and a GPS positioning module 11 is coupled to the intelligent control device 1. Since the various actions of the electric vehicle, such as braking, acceleration, opening and closing, and lighting, are all executed by the corresponding control signals sent by the central control of the electric vehicle to control the relevant components, in addition, the central control of the electric vehicle is coupled with sensors such as speed sensors, photosensitive sensors, power probes, and temperature sensors to feedback and detect the speed, light brightness, battery power, and battery temperature of the electric vehicle to obtain corresponding feedback information. The intelligent control device 1 can determine whether the electric vehicle has a fault after judging based on the control signal and the feedback information. For example, after the control signal for controlling the operation of the electric vehicle motor is sent, the electric vehicle motor does not run, indicating that the circuit where the electric vehicle motor is located is faulty, and the vehicle status information of the vehicle power system fault is output; for another example, after the control signal for controlling the lighting of the electric vehicle is sent, the photosensitive sensor does not detect the corresponding intensity of light, indicating that the circuit where the electric vehicle lighting is located is faulty, and the vehicle status information of the vehicle lighting circuit fault is output; for another example, the temperature sensor will detect the battery temperature of the electric vehicle, and when the battery temperature is higher than the preset temperature standard value in the intelligent control device 1, the vehicle status information of the battery fault is output.

[0050] The intelligent control device 1 collects battery power information, speed information, positioning information and vehicle product serial number information. The battery power information is obtained by detecting the power of the battery on the electric vehicle through the power probe, the speed information is obtained by detecting the speed of the motor output shaft through the speed sensor, the positioning information is obtained by detecting the position of the electric vehicle by the GPS positioning module 11, and the vehicle product serial number information is information pre-stored in the electric vehicle central control. After the intelligent control device 1 collects these signals in real time, the intelligent control device 1 packages these information into combined information, sends it to the 4G communication module 3, and sends it to the background server 2 through the 4G communication module 3.

[0051] Reference Figure 1 and Figure 2 , the backend server 2, adopts a PC terminal, and has a signal receiving and sending function. After the 4G communication module 3 sends the combined information, it will be received by the backend server 2. The backend server 2 then obtains the electric vehicle state parameters according to the combined information;

[0052] The backend server 2 includes a matching module 11, a result acquisition module 12, a processing module 13, a query module 14, a wireless communication module 15, a flow statistics module 17, a flow acquisition module 172, a communication control module 16, a vehicle statistics module 18 and a vehicle type statistics module 19. It should be noted that the above modules are all system function modules in the backend server 2.

[0053] The matching module 11 has a vehicle communication flow table pre-stored therein, which includes the vehicle product serial number and the corresponding flow value. The specific code of the vehicle product serial number information in the combination information sent by the intelligent control device 1 on each electric vehicle can find the corresponding vehicle product serial number in the vehicle communication flow table. After the matching module 11 receives the combination information, it will traverse the vehicle communication flow table according to the vehicle product serial number information in the combination information to find the corresponding vehicle product serial number and the corresponding flow value.

[0054] After obtaining the vehicle product serial number of the electric vehicle and the corresponding flow value, the result acquisition module 12 will compare the flow value with the preset flow standard value, the preset flow standard value is 0, when the flow value is less than or equal to 0, a failure result is obtained; when the flow value is greater than 0, a passing result is obtained;

[0055] After obtaining the pass result, the traffic statistics module 17 will count the data size of the received combination information to obtain the traffic statistics value, and then the traffic consumption module 171 will reduce and update the traffic value corresponding to the combination information according to the traffic statistics value, so that the traffic value is reduced by the same value as the traffic statistics value. When the traffic value is reduced to 0 or lower, it will trigger the fail result; in order to supplement the traffic, the application uses the traffic acquisition module 172, which can obtain the traffic recharge information sent by the handheld terminal 4, and update the traffic value corresponding to the handheld terminal 4 according to the traffic recharge information to increase the value of the traffic value. For example, if a person recharges 10M of traffic, the traffic acquisition module 172 will receive the corresponding traffic recharge information and increase the traffic value by 10M.

[0056] The processing module 13 is used to process the combined information according to the result and obtain the corresponding electric vehicle state parameters. The electric vehicle state parameters include information such as remaining power, estimated riding mileage, total riding mileage, user corresponding model, specific location, battery information, riding trajectory and vehicle state information. After obtaining the electric vehicle state parameters, the processing module 13 will store the electric vehicle state parameters in the storage area of ​​the backend server 2. Incidentally, the backend personnel can count the fault conditions of the electric vehicle according to the vehicle state information in the electric vehicle state parameters in the storage area, so as to optimize vehicle production. After that, the query module 14 can traverse the preset handheld terminal contact table in its internal part to obtain the corresponding handheld terminal 4 contact information according to the vehicle product serial number information in the combined information. Among them, the handheld terminal contact table pre-stores the handheld terminal 4 contact information corresponding to the vehicle product serial number. After that, after obtaining the corresponding handheld terminal 4 contact information, the wireless communication module 15 sends the corresponding electric vehicle state parameters of the electric vehicle to the corresponding handheld terminal 4 according to the handheld terminal 4 contact information. It is convenient for personnel to understand the status of the electric vehicle in a timely manner and to find faults in time for maintenance.

[0057] It should be noted here that the flow recharge information can also be accurately recharged through the pairing of the handheld terminal 4 contact information, the vehicle product serial number and the flow value.

[0058] The vehicle statistics module 18 is used to count the total number of online vehicles according to the vehicle product serial number information in the combined information received at the same time. Because the product serial number of each electric vehicle is different, and only after the electric vehicle is started, the intelligent control device 1 will activate and send the combined information. The vehicle statistics module 18 can count how many vehicles are in use by identifying the vehicle product serial number information. The vehicle model statistics module 19 is pre-set with a vehicle model table, and the vehicle product serial number and its corresponding vehicle model are stored in the vehicle model table. It is used to traverse the vehicle model table according to the vehicle product serial number information in the combined information to obtain the vehicle model, and count the proportion of electric vehicles of each model to the total number of online vehicles in the time period and display it. There are many types of electric vehicle models, and each model has produced a number of electric vehicles, which also has a number of vehicle product serial numbers. By traversing the model table, the vehicle statistics module 18 can count the proportion of each model to the total number of online vehicles, and display the model proportion on the display screen coupled to the backend server 2. It is convenient for personnel to analyze the sales of various types of electric vehicles.

[0059] In addition, after obtaining the failed result, the communication control module 16 will send a locking signal according to the failed result. After receiving the locking signal, the intelligent control device 1 will turn off the signal sending function of the 4G communication module 3, so that the 4G communication module 3 only receives data and does not send the combination information to the background server 2, which can reduce the waste of electricity. After the personnel recharge with the handheld terminal 4, the flow value returns to the interval greater than 0, and the result acquisition module 12 re-acquires the passing result. The background server 2 sends an unlocking signal according to the passing result. After receiving the unlocking signal, the intelligent control device 1 will reopen the signal sending function of the 4G communication module 3.

[0060] Since the 4G communication module 3 does not send the combination information during the period when the personnel use the handheld terminal 4 to recharge the traffic, the backend server 2 does not store the electric vehicle status parameters, and there will be a period of information loss. In order to make up for the information loss problem during this period, the intelligent control device 1 is coupled with a memory 13. After the signal sending function of the 4G communication module 3 is turned off, the intelligent control device 1 inputs the combination information into the memory 13 for storage and real-time update after receiving the locking signal, so that the combination information is temporarily stored in the memory 13. The intelligent control device 1 also includes a reading module 12, which is a system module inside the intelligent control device 1. The reading module 12 is used to start when the unlocking signal is received for the first time after receiving the locking signal to read the combination information in the memory 13. At the same time, the intelligent control device 1 stops inputting the combination information into the memory 13, and sends the read combination information and the additional read tag to the backend server 2 through the 4G communication module 3 in sequence. After the backend server 2 reads the combination information with the read tag, it will directly store the combination information in the storage area in the order of reception, which is convenient for personnel to view. In order to avoid excessive data storage in the storage area, which leads to excessive combination information that needs to be sent by the 4G communication module 3 and affects the normal sending of the combination information, the intelligent control device 1 also includes an interval sending module 15. Between the time when the 4G communication module 3 sends the combination information and the time when the next combination information is sent, the interval sending module 15 will send multiple labeled combination information to the 4G communication module 3 in sequence, and the 4G communication module 3 will send them to the background server 2 for data supplement.

[0061] In addition, it should be noted that the backend server 2 also pre-stores a personnel data table, which includes a user image and a vehicle product serial number corresponding to the user portrait. The backend server 2 can analyze the user image through a built-in program to estimate the user's age, generate electronic coordinates in the internal preset electronic map according to the positioning information in the combination information, and then match the vehicle product serial number with the combination information, and attach the age information to the corresponding electronic coordinates in the form of a label. In addition, the vehicle model and other information can also be attached to the electronic coordinates in the form of a label, and the electronic map and electronic coordinates are displayed on the display screen, which is convenient for the backend personnel to understand the age and preferred vehicle model of the users using electric vehicles in various regions, so as to make subsequent production adjustments. In addition, the backend server 2 will analyze the electric vehicle state parameters in the storage area to form user riding records and riding statistics. The user riding record includes the moving path of the electronic coordinates when the vehicle is online once, the remaining battery power and other information. The user riding statistics are the number of times the vehicle is online within the preset time. In this embodiment, it is the number of times the user's vehicle is online every day. The backend server 2 will send the user's riding records for the last 5 times and the riding statistics for 60 days to the user's handheld terminal 4 through the 4G communication module 3. It is convenient for personnel to understand. In addition, the intelligent control device 1 is also coupled to a smart lock 14 for locking the seat or trunk of the electric vehicle. The background server 2 can also control the intelligent control device 1 to open or close the smart lock 14 through the 4G communication module 3.

[0062] The implementation principle of the monitoring and management system of an electric vehicle with 4G communication function in the embodiment of the present application is: by setting up a 4G communication module 3 and a background server 2, a communication connection is established between the electric vehicle central control (intelligent control device 1) and a personnel mobile phone handheld terminal 4, so that personnel can monitor the electric vehicle from a long distance and can quickly perceive the situation of the electric vehicle.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
