Detailed embodiments

[0016] For a better understanding of the technical features, purposes and effects of the present application, specific embodiments of the present application are described with reference to the attached drawings, wherein the same symbols in the respective drawings indicate components with the same or similar structure but with the same function.

[0017] As described in the background technology, with the development of engine intelligence, more and more data collected by the engine needs to be processed in the cloud. A common method for remote data transmission is that the engine control module manufacturer sends the information data that needs to be uploaded to the cloud server to the data transmission manufacturer, and the data transmission manufacturer sends the information data to the cloud. This results in the control module manufacturer's information data being insecure, resulting in leaks, and the data transmission line between the control module and the connected data transmission module is easily interrupted, resulting in incomplete data transmission.

[0018] According to one aspect of the present application, a remote data transmission system for vehicles is provided as described in Fig. 1, which includes a control module 20, a transmission module 60, an encryption module 70, an enabling module 40, a power supply 30, and a temperature detection module 50 integrated on a circuit board 10, wherein the transmission module 60 includes a 4G communication module 601; wherein the control module 20 is connected to the 4G communication module 601 to perform data exchange with the 4G communication module 601 and data exchange with the cloud server via the 4G communication module 601; the control module 20 is connected to the temperature detection module 50 and is capable of receiving temperature detection information and controlling the working conditions of the 4G communication module 601 based on the temperature detection information; the encryption module 70 is connected to the 4G communication module 601;the enable module 40 is connected in series between the power supply 30 and the transmission module 60, and the enable module 40 is connected to the control module 20 to receive an enable signal sent from the control module 20 to change the operating state;

[0019] In one embodiment, the control module 20 is connected to the 4G communication module 601. After the control module 20 receives the vehicle's detection data, operation data, etc., it can send the data to the 4G communication module 601, and the 4G communication module 601 sends the data sent from the control module 20 to the cloud server. The control module 20 is also connected to the temperature detection module 50 to receive the temperature detection information of the data transmission system acquired by the temperature detection module 50 and control the working conditions of the 4G communication module 601 according to the temperature detection information. The 4G communication module 601 is connected to the encryption module 70 to perform encryption protection of the data transmission and improve the security of the data transmission.The enabling module 40 is connected in series between the power supply 30 and the transmission module 60, and the control module 20 can change the operating state of the enabling module 40 by sending an enabling signal to the enabling module 40. The enabling module 40 can be at least one control switch. When the enabling signal sent by the control module 20 is received, the control switch is turned on. When the transmission module 60 is disconnected from the power supply 30, the operation of the 4G communication module 601 is stopped, thereby controlling the working conditions of the 4G communication module. By integrating the control module 20, the transmission module 60, the encryption module 70, the enabling module 40, the power supply 30, and the temperature detection module 50 on the board 10, it is possible to avoid data transmission failures due to connection interruptions between different modules.At the same time, the user sets the module that can output data together with the cloud server as the 4G communication module 601. Then, the acquired data related to the engine control module 20 can be transmitted to the cloud server within the user, which improves the level of data protection.

[0020] As an exemplary embodiment, the transmission module 60 comprises, as shown in Fig. 2, also an antenna 602 and a SIM card 603; wherein the 4G communication module 601 is connected to the control module 20, the antenna 602, and the SIM card 603, respectively.

[0021] In one embodiment, the antenna 602 realizes the wireless remote connection between the 4G communication module 601 and the cloud server, and the SIM card 603 provides communication services for the 4G communication module 601, and the antenna 602 and the SIM card 603 are connected to the 4G communication module 601 to ensure the normal communication function of the 4G communication module 601.

[0022] As an exemplary embodiment, the temperature sensing module 50 comprises, as shown in Fig. 3, a first temperature sensor 501 for detecting the first temperature value of the control module 20 and a second temperature sensor 502 for detecting the second temperature value of the 4G communication module 601; wherein the first temperature sensor 501 and the second temperature sensor 502 are each connected to the control module 20.

[0023] In one embodiment, the temperature detection module 50 can enable temperature detection of the vehicle's remote data transmission system. Among other things, the first temperature sensor 501 can detect the first temperature value of the control module 20. By detecting the first temperature value of the control module 20 in real time, it can be determined whether the control module 20 is operating within an efficient temperature range, and the temperature range can be measured experimentally; the second temperature sensor 502 can detect the second temperature value of the 4G communication module 601. The first temperature sensor 501 and the second temperature sensor 502 detect the operating temperatures of the control module 20 and the 4G communication module 601 in real time to determine whether the currently operating control module 20 and the 4G communication module are at risk of burning out the control module 20 or the 4G communication module 601 due to overheating.If the temperature value detected by the first temperature sensor 501 or the second temperature sensor 502 is higher than the maximum temperature value allowed for the operation of the control module 20 or the 4G communication module 601, the control module 20 or the 4G communication module 601 may stop operating at that time. Cooling modules may also be used to cool the control module 20 and the 4G communication module 601 to ensure the normal operation of the control module 20 and the 4G communication module 601 and improve the reliability of the remote data transmission system.

[0024] As an exemplary embodiment, the remote data transmission system for vehicles as shown in Fig. 4, furthermore a cooling module 110, which is arranged closely with the transmission module 60 and is designed to cool the transmission module 60.

[0025] In one embodiment, the vehicle remote data transmission system further includes a cooling module 110, the arrangement of which may be mounted closely to the transmission module 60 or closely to the entire circuit board 10, to cool the control module 20 and the 4G communication module 601 and thereby protect the control module 20 and the 4G communication module 601 from high temperatures. The cooling module 110 may, for example, be an oil cooling pipe or a controllable fan electrically connected to the control module 20.

[0026] As an exemplary embodiment, the remote data transmission system for vehicles as shown in Fig. 5, further includes a level conversion chip 80, one end of the level conversion chip 80 being connected to the control module 20 and the other end being connected to the transmission module 60.

[0027] In one embodiment, the control module 20 and the 4G communication module 601 may have a mismatch between the circuit levels of the control module 20 and the 4G communication module 601 for selection reasons. Therefore, a level conversion circuit must be implemented on the data transmission line between the control module 20 and the 4G communication module 601 to achieve level conversion and ensure normal data transmission between the control module 20 and the 4G communication module 601.

[0028] As an exemplary embodiment, the remote data transmission system for vehicles as shown in Fig. 6, furthermore, a storage module connected to the control module 20 for storing remote data. The storage module comprises a first storage unit 90 and a second storage unit 100; wherein the first storage unit 90 is connected to the control module 20 and configured to store remote data sent from the cloud server; wherein the second storage unit 100 is connected to the control module 20 and configured to store data to be transmitted to the cloud server.

[0029] In one embodiment, the data transmitted from the cloud database to the control module 20 via the 4G communication module 601 and the data to be transmitted from the control module 20 to the cloud server via the 4G communication module 601 can be stored in the storage module. Specifically, the storage module includes a first storage unit 90 and a second storage unit 100. After the cloud server transmits the remote data to the control module 20 via the 4G communication module 601, the control module 20 stores the remote data in the first storage unit 90 and calibrates the stored remote data.A brush-write upgrade of the remote data is performed after calibration is completed. When the control module 20 transmits the detection data to the 4G communication module 601 and the data transmission speed is slow, the data to be transmitted can be stored in the second storage unit 100 and uploaded in batches; or the upload can be stopped when the data transmission speed is slow and resumed when the data transmission speed is high. The data transmission speed can be measured experimentally, and the data transmission speed can be directly determined from the 4G communication module 601.By storing the remote data received by the control module 20 and the data to be transmitted in different storage units, the reliability of the data transmission is ensured and incomplete data transmission is avoided when the data transmission is slow or the connection to the network is interrupted.

[0030] According to a further aspect, an embodiment of the present application provides a control method for a remote data transmission system for vehicles, wherein the remote data transmission system comprises a control module 20, a first temperature sensor 501, a second temperature sensor 502, a cooling module 110 and a transmission module 60, each connected to the control module 20, as shown in Fig. 7, wherein the control method comprises:

[0031] Step S10. The control module 20 obtains a first temperature value representing the current temperature of the control module 20 based on the first temperature sensor 501, and obtains a second temperature value representing the current temperature of the transmission module 60 based on the second temperature sensor 502;

[0032] In step S20, if the first temperature value is greater than the first preset value and the second temperature value is greater than the second preset value, the control module 20 controls the transmission module 60 to stop its operation and the cooling module 110 to start working; or, if the first temperature value is greater than the first preset value or the second temperature value is greater than the second preset value, the control module 20 controls the transmission module 60 to stop its operation and the cooling module 110 to start working.

[0033] In one embodiment, during operation of the remote data transmission system, the control module 20 receives a first temperature value and a second temperature value based on the first temperature sensor 501 and the second temperature sensor 502. If the control module 20 analyzes that the first temperature value is greater than the first preset value and / or the second temperature value is greater than the second preset value, this means that the operating temperature of the control module 20 has reached the limit value and / or the operating temperature of the transmission module 60 has reached the limit value at this time. If the control module 20 and / or the transmission module 60 continue to operate in their current state at this time, a burnout may occur.Therefore, at this time, the control module 20 may first control the transmission module 60 to stop its operation and control the cooling module 110 to cool the control module 20 and the transmission module 60 to avoid a situation where the operating temperatures of the control module 20 and the transmission module 60 are too high and result in burnout.

[0034] As an exemplary embodiment, the remote data transmission system for vehicles further includes a second storage unit 100 connected to the control module 20 for storing data to be transmitted to the cloud server, the control method further comprising: the control module 20 determining the current network transmission speed based on the transmission module 60; if the network transmission speed is lower than the preset transmission speed, the control module 20 controlling the second storage unit 100 to stop data transmission; if the network transmission speed is greater than the preset transmission speed, the control module 20 controlling the second storage unit 100 to start data transmission.

[0035] In one embodiment, if the control module 20 obtains the network transmission speed of the current transmission module 60 and the network transmission speed is lower than the preset transmission speed, it means that the network speed at that time is low. If the transmission module 60 transmits data to the cloud server at that time, the efficiency is low and there is a risk of data transmission errors occurring. Therefore, at that time, the control module 20 controls the second storage unit 100 to stop transmitting data, so that the data is temporarily stored in the second transmission module 60; if the network transmission speed is greater than the preset transmission speed, it means that the network speed at that time can better realize data transmission.At this time, the second storage unit 100 is controlled to continue the transmission, and the data is transmitted to the cloud server via the transmission unit to ensure the efficiency and integrity of the data transmission.
