Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to an embedded dynamic random access memory system. Background Art

[0002] As an important computer memory device, random access memory has been widely used in modern electronic devices. Traditional random access memory is mainly divided into static random access memory and dynamic random access memory. However, with the development of electronic devices and the diversification of application scenarios, traditional random access memory has some problems.

[0003] First of all, the traditional static random access memory has the advantages of fast access speed and data stability due to the use of stable storage circuits, but it inevitably faces the problems of high power consumption and large space occupation, which limits its application in applications with high power consumption and space requirements such as embedded systems.

[0004] Secondly, the traditional dynamic random access memory has a high storage density and relatively low power consumption due to the use of capacitor storage units, but it needs to continuously refresh the capacitor to maintain data stability, resulting in slow access speed and susceptibility to electromagnetic interference, and has high requirements for signal retention time. The rise of new energy vehicles has driven the sales of random access memories to rise. According to the demand of new energy vehicles, different numbers of random access memories are installed on new energy vehicles. How to maintain a continuous connection between each random access memory to ensure that there is no time interval in information transmission and to ensure low power consumption during transmission requires the design of an embedded dynamic random access memory system. Summary of the invention

[0005] The object of the present invention is to provide an embedded dynamic random access memory system to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an embedded dynamic random storage system, comprising a position designation module, a data analysis module and a storage module, wherein the position designation module comprises an embedded grid area positioning unit, an embedded grid data independent storage unit and an embedded grid data transmission unit.

[0007] The embedded grid area positioning unit includes an embedded grid and dynamic memory connection monitoring component and an embedded grid position confirmation component.

[0008] The embedded cell and dynamic memory connection monitoring component is used to monitor the structural stability and power supply stability between the embedded cell and the dynamic memory.

[0009] The embedded grid orientation confirmation component is used to independently monitor the dynamic memories in the embedded grids in different directions.

[0010] Each dynamic memory in the new energy vehicle is responsible for storing different data sources. The dynamic memory stores the received data and waits for the transmission instruction. The embedded grid is connected to the dynamic memory. The monitoring component judges the structural stability of the dynamic memory through the pressure sensor installed in the embedded grid. The embedded grid is connected to the dynamic memory. The monitoring component sets the pressure value detected by the pressure sensor to F 压力 , F 压力 It is divided into stable pressure value and removable pressure value. If the value detected by the pressure sensor is a stable pressure value, it means that the structure of the dynamic memory is stable. If the value detected by the pressure sensor is a removable pressure value, it means that the structure of the dynamic memory is in an unstable state. The new energy vehicle APP and the new energy internal alarm will remind the owner that the dynamic memory needs maintenance.

[0011] When the dynamic memory is installed in the embedded cell, it is necessary to connect the plug-in on the dynamic memory with the wires in the embedded cell so that the data of the dynamic memory can be transmitted. A micro switch is set in the plug-in on the dynamic memory. When the wires in the embedded cell are inserted into the plug-in, the micro switch is pressed. At this time, it is determined that the power supply between the embedded cell and the dynamic memory is stable. If the micro switch is pressed to start, there is a passive reset or reset trend of the micro switch, then it is determined that the power supply between the embedded cell and the dynamic memory is in an unstable state.

[0012] The embedded grid position confirmation component ensures that the position of each dynamic memory can be obtained in real time through the positioning sensor. A positioning sensor 1 is installed in each embedded grid, and a positioning sensor 2 is installed at the central processor of the new energy vehicle. The position of each positioning sensor 1 is obtained through the positioning sensor 2.

[0013] According to the above technical solution, the embedded grid data independent storage unit includes a dynamic memory refresh, a dynamic memory independent energy consumption monitoring and a dynamic memory independent power supply module.

[0014] The dynamic memory refresh ensures the stability of the data stored in the dynamic memory by continuously refreshing the dynamic memory, and divides the dynamic memory refresh into an independent refresh mode and a centralized refresh mode. The independent refresh mode is for each dynamic memory to autonomously refresh data, and the centralized refresh mode is for transferring the data in each dynamic memory to the central processor of the new energy vehicle, and refreshing the data of all dynamic memories in the central processor of the new energy vehicle. The dynamic memory refresh divides the new energy vehicle into a power storage state and a power-off state. The new energy vehicle in the power storage state is always in a power supply state. The dynamic memory refresh adopts an independent refresh mode, and several dynamic memories are independently refreshed to ensure that the data of each dynamic memory is stored stably. There is no energy consumption concern for the new energy vehicle in the power storage state, and there is no additional power supply for the new energy vehicle in the power-off state. The centralized refresh mode is adopted to turn off the independent refresh function of all dynamic memories.

[0015] The independent energy consumption monitoring of the dynamic memory is performed by installing an electric energy monitor on the dynamic memory. Each dynamic memory is configured with an electric energy monitor, and the data of each electric energy monitor is connected to the central processor of the new energy vehicle. The electric energy monitor is set to sleep mode and running mode. The sleep mode is that during the power storage process of the new energy vehicle, the electric energy monitor does not monitor the energy consumption of the dynamic memory, and records the initial time and end time of this time period. The running mode is that when the new energy vehicle is powered off and there is no additional power supply, the electric energy monitor starts to monitor the dynamic memory. The electric energy monitor transmits energy consumption data once every 10 seconds, and transmits the data to the central processor of the new energy vehicle. The energy consumption is verified and detected every 10 seconds by the central processor of the new energy vehicle. If the energy consumption of the dynamic memory within the interval exceeds the verification data, it means that the data refresh energy consumption in this dynamic memory is large, and this dynamic memory is marked as a high-energy consumption dynamic memory. If two high-energy consumption dynamic memories appear, the high-energy consumption dynamic memory is forced to be changed to a centralized refresh mode.

[0016] The independent power supply module of the dynamic memory is configured with multiple power supply paths, and one power supply path is configured for one dynamic memory, which is convenient for energy consumption monitoring by the electric energy monitor. At the same time, the independent power supply module ensures that when a power supply failure occurs in one dynamic memory, the operation of other dynamic memories is not affected.

[0017] According to the above technical solution, the embedded grid data transmission unit includes a dynamic memory transmission interface and a new energy vehicle central processor transmission interface. Each of the dynamic memory transmission interfaces is connected to the new energy vehicle central processor transmission interface. The new energy vehicle central processor transmission interface is a normally open interface. The dynamic memory transmission interface performs an independent opening and closing process according to the power storage status of the new energy vehicle and the energy consumption of the dynamic memory. The embedded grid data transmission unit provides a stable and secure data transmission path for the low-energy operation of the dynamic memory.

[0018] According to the above technical solution, the data analysis module includes data volume monitoring, data volume differentiation, and data passive transmission.

[0019] The data volume monitoring is performed by monitoring the memory status of each dynamic memory, and the dynamic memory is divided into low memory dynamic memory, high memory dynamic memory and overload dynamic memory according to the memory status of the dynamic memory.

[0020] According to the above technical solution, the low memory dynamic memory indicates that the amount of data in the dynamic memory occupies less than 50% of the total memory, excluding 50%; the high memory dynamic memory indicates that the amount of data in the dynamic memory occupies 50%-70% of the total memory, including 50%; the overload dynamic memory indicates that the amount of data in the dynamic memory occupies more than 70% of the total memory, including 70%; the data volume monitoring transmits the real-time memory share of each dynamic memory to the central processor of the new energy vehicle.

[0021] The data volume monitoring is carried out when there is only one high-energy consumption dynamic memory. By comparing the memory share data of each dynamic memory, the new energy vehicle central processor selects the dynamic memory with the smallest memory share, and connects this dynamic memory with the dynamic memory transmission interface of the high-energy consumption dynamic memory, and transmits the data in the high-energy consumption dynamic memory to this dynamic memory. A 10% external data share is reserved in each dynamic memory. If the transmission data in the high-energy consumption dynamic memory exceeds the 10% external data share reserved in this dynamic memory, the data volume monitoring continues to select the next dynamic memory with the smallest memory share, and repeats the data transmission until the memory share of a single high-energy consumption dynamic memory decreases. As the memory share of the high-energy consumption dynamic memory decreases, the energy consumption of the dynamic memory also decreases.

[0022] According to the above technical solution, the data volume is differentiated by dividing the storage space in each dynamic memory into a main memory space and a preset memory space. External data can only enter the preset memory space, and the entry path of the external data is marked. Only one data path is allowed to enter each dynamic memory to ensure data stability. When the dynamic memory for data output is changed to a low-memory dynamic memory, the data is returned from the preset memory space through the marked path again.

[0023] According to the above technical solution, the passive data transmission is used to control data docking, that is, the data in one dynamic memory is output to another dynamic memory and can only be docked into the preset memory space in another dynamic memory, further limiting the data transmission path.

[0024] According to the above technical solution, the storage module includes space layout and storage data encryption.

[0025] According to the above technical solution, the storage data encryption is to divide all dynamic memories according to directions, and encrypt some dynamic memories on new energy vehicles. That is, the dynamic memories with encryption settings cannot be passively transmitted with other dynamic memories through data, and the encrypted dynamic memories need to be manually processed through the new energy vehicle central processor.

[0026] According to the above technical solution, the storage module includes a spatial layout that divides the space in the entire dynamic memory into a first storage space, a second storage space, a third storage space and a fourth storage space, which correspond to the low memory dynamic memory, the high memory dynamic memory, the overload dynamic memory and the preset memory space respectively. The first storage space, the second storage space and the third storage space constitute the main memory space, and data is stored in sequence in a progressive storage manner by the first storage space, the second storage space and the third storage space.

[0027] Compared with the prior art, the beneficial effect achieved by the present invention is that the present invention, by providing an embedded cell and dynamic memory connection monitoring component and an embedded cell orientation confirmation component, monitors the structural stability and power supply stability of the dynamic memory, thereby providing stable prerequisites for the operation of the dynamic memory.

[0028] By setting up a dynamic memory refresh, all the data in the dynamic memory is transferred to the central processor of the new energy vehicle, refreshed once, and then the refreshed data is sent back to complete a data refresh, thereby reducing refresh energy consumption and improving the overall power storage efficiency of the new energy vehicle.

[0029] By providing an embedded cell data transmission unit, the embedded cell data transmission unit provides a stable and secure data transmission path for the low-power operation of the dynamic memory, while maintaining data stability and providing a fast access speed.

[0040] By monitoring the structural stability and power supply stability of the dynamic memory, stable prerequisites are provided for the operation of the dynamic memory.

[0041] The embedded grid data independent storage unit includes a dynamic memory refresh, a dynamic memory independent energy consumption monitoring and a dynamic memory independent power supply module;

[0042] Dynamic memory refresh ensures the stability of data stored in the dynamic memory by continuously refreshing the dynamic memory. The dynamic memory refresh is divided into independent refresh mode and centralized refresh mode. The independent refresh mode is for each dynamic memory to refresh data independently. The centralized refresh mode is for transferring the data in each dynamic memory to the new energy vehicle central processor, and refreshing the data of all dynamic memories in the new energy vehicle central processor. The dynamic memory refresh divides new energy vehicles into a storage state and a power-off state. New energy vehicles in the storage state are always in a power supply state. The dynamic memory refresh adopts an independent refresh mode, and several dynamic memories are refreshed independently to ensure that the data of each dynamic memory is stored stably. In addition, new energy vehicles in the storage state have no energy consumption concerns, and new energy vehicles in the power-off state have no additional power supply. The centralized refresh mode is adopted to turn off the independent refresh function of all dynamic memories. By transferring all the data in the dynamic memory to the new energy vehicle central processor, a centralized refresh is performed, and the refreshed data is transmitted back to complete a data refresh, thereby reducing refresh energy consumption and improving the overall power storage efficiency of new energy vehicles.

[0043] Independent energy consumption monitoring of dynamic memory is performed by installing an energy monitor on the dynamic memory. Each dynamic memory is configured with an energy monitor, and the data of each energy monitor is connected to the central processor of the new energy vehicle. The energy monitor is set to sleep mode and running mode. In sleep mode, the energy monitor does not monitor the energy consumption of the dynamic memory during the power storage process of the new energy vehicle, and records the initial time and end time of this time period. In running mode, when the new energy vehicle is powered off and there is no additional power supply, the energy monitor starts to monitor the dynamic memory. The energy monitor transmits energy consumption data once every 10 seconds, and transmits the data to the central processor of the new energy vehicle. The energy consumption is verified and tested every 10 seconds by the central processor of the new energy vehicle. If the energy consumption of the dynamic memory within the interval exceeds the verification data, it means that the data refresh energy consumption in this dynamic memory is large, and this dynamic memory is marked as a high-energy dynamic memory. If two high-energy dynamic memories appear, the high-energy dynamic memory is forced to change to a centralized refresh mode.

[0044] The data in the dynamic memory can be deleted through the central processor of the new energy vehicle, thereby reducing the energy consumption of the dynamic memory;

[0045] The independent power supply module of the dynamic memory sets multiple power supply paths, and one dynamic memory is configured with one power supply path, which is convenient for energy consumption monitoring by the power monitor. At the same time, the independent power supply module ensures that when a power supply failure occurs in a dynamic memory, the operation of other dynamic memories is not affected.

[0046] The embedded grid data transmission unit includes a dynamic memory transmission interface and a new energy vehicle central processing unit transmission interface. Each dynamic memory transmission interface is connected to the new energy vehicle central processing unit transmission interface. The new energy vehicle central processing unit transmission interface is a normally open interface. The dynamic memory transmission interface performs independent opening and closing processes according to the power storage status of the new energy vehicle and the energy consumption of the dynamic memory. The embedded grid data transmission unit provides a stable and secure data transmission path for the low-energy operation of the dynamic memory, while maintaining data stability and providing fast access speed. The small size design of the embedded dynamic memory meets the needs of vehicles with higher space requirements.

[0047] The data analysis module includes data volume monitoring, data volume differentiation, and data passive transmission;

[0048] Data volume monitoring monitors the memory status of each dynamic memory and divides the dynamic memory into low memory dynamic memory, high memory dynamic memory and overload dynamic memory according to the memory status of the dynamic memory;

[0049] Low memory dynamic memory means that the amount of data in the dynamic memory occupies less than 50% of the total memory, excluding 50%. High memory dynamic memory means that the amount of data in the dynamic memory occupies 50%-70% of the total memory, including 50%. Overload dynamic memory means that the amount of data in the dynamic memory occupies more than 70% of the total memory, including 70%. Data volume monitoring transmits the real-time memory share of each dynamic memory to the central processor of the new energy vehicle;

[0050] Data volume monitoring is when there is only one high-energy dynamic memory. By comparing the memory share data of each dynamic memory, the new energy vehicle central processor selects the dynamic memory with the smallest memory share, and connects this dynamic memory with the dynamic memory transmission interface of the high-energy dynamic memory, and transmits the data in the high-energy dynamic memory to this dynamic memory. 10% of external data is reserved in each dynamic memory. If the transmission data in the high-energy dynamic memory exceeds the reserved 10% external data share in this dynamic memory, the data volume monitoring continues to select the next dynamic memory with the smallest memory share, and repeats the data transmission until the memory share of a single high-energy dynamic memory decreases. As the memory share of the high-energy dynamic memory decreases, the energy consumption of the dynamic memory also decreases.

[0051] Data volume differentiation is achieved by dividing the storage space in each dynamic memory into main memory space and preset memory space. External data can only enter the preset memory space, and the entry path of external data is marked. Only one data path is allowed to enter each dynamic memory to ensure data stability. When the dynamic memory for data output is changed to a low-memory dynamic memory, the data is returned from the preset memory space through the marked path again.

[0052] Passive data transmission is used to control data docking, that is, data in one dynamic memory is output to another dynamic memory and can only be docked into the preset memory space in another dynamic memory, further limiting the data transmission path.

[0053] The storage module includes space layout and storage data encryption;

[0054] Storage data encryption is to divide all dynamic memories according to location, and encrypt some dynamic memories on new energy vehicles. That is, the encrypted dynamic memories cannot be passively transmitted with other dynamic memories. The encrypted dynamic memories need to be manually processed through the new energy vehicle central processor to ensure the security of data in the partially encrypted dynamic memories.

[0055] The storage module includes a spatial layout that divides the space within the entire dynamic memory into a first storage space, a second storage space, a third storage space and a fourth storage space, which correspond to a low memory dynamic memory, a high memory dynamic memory, an overload dynamic memory and a preset memory space, respectively. The first storage space, the second storage space and the third storage space constitute the main memory space, and data is stored in sequence in a progressive storage manner by the first storage space, the second storage space and the third storage space.
