Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic diagram of a peripheral chip initializing device in a hardware running environment according to an embodiment of the present invention.
As shown in fig. 1, the peripheral chip initializing device may include: a processor 1001, such as a central processing unit (Central Processing Unit, CPU), a communication bus 1002, a user interface 1003, a network interface 1004, a memory 1005. Wherein the communication bus 1002 is used to enable connected communication between these components. The user interface 1003 may include a Display, an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may further include a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a Wireless interface (e.g., a Wireless-Fidelity (Wi-Fi) interface). The Memory 1005 may be a high-speed random access Memory (Random Access Memory, RAM) or a stable nonvolatile Memory (NVM), such as a disk Memory. The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.
Those skilled in the art will appreciate that the structure shown in fig. 1 does not constitute a limitation on the peripheral chip initialization apparatus, and may include more or fewer components than shown, or may combine certain components, or may have a different arrangement of components.
As shown in fig. 1, an operating system, a network communication module, a user interface module, and a peripheral chip initialization program may be included in the memory 1005 as one type of storage medium.
In the peripheral chip initializing device shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the peripheral chip initializing device of the present invention may be disposed in the peripheral chip initializing device, and the peripheral chip initializing device calls the peripheral chip initializing program stored in the memory 1005 through the processor 1001 and executes the peripheral chip initializing method provided by the embodiment of the present invention.
An embodiment of the present invention provides a peripheral chip initializing method, and referring to fig. 2, fig. 2 is a flowchart of a first embodiment of the peripheral chip initializing method of the present invention.
In this embodiment, the peripheral chip initializing method includes the following steps:
Step S10: and when initializing the peripheral chip, acquiring an initialization writing value.
It should be noted that, the execution body of the embodiment may be a peripheral chip initializing device, for example, a controller in a single chip microcomputer, or may be other devices capable of implementing the same or similar functions, which is not limited in this embodiment, and the peripheral chip initializing device is exemplified in this embodiment.
As shown in fig. 3, fig. 3 is a schematic flow chart of the current initialization of the peripheral chip, after the system is powered on, the single chip may perform necessary function configuration on the peripheral chip through communication modes such as spi\uart\i2c, i.e. the initialization, the initialization flow of the peripheral chip is usually performed only once, and there is no verification mechanism, and then the system enters a normal running state, but if the initialization fails, the system functions are affected, and since there is no fault record, the cause locking during the problem investigation is difficult, thereby resulting in poor initialization effect. In order to ensure safety, the initialization abnormal state of the peripheral chip is monitored in real time, and when the initialization is abnormal, protection treatment measures are timely taken to ensure the normal function of the system to the greatest extent.
Therefore, the embodiment provides a peripheral chip initializing method, which monitors the initializing state of each peripheral chip in real time in the power-on initializing stage, acquires the actual initializing value and compares the actual initializing value with the preset value, considers that the initializing process is abnormal when the actual initializing value and the preset value are inconsistent, and adopts targeted protection measures according to the chip functions and the controller types, thereby realizing the system functions most efficiently and safely. As shown in fig. 4, fig. 4 is a schematic overall flow chart of initializing peripheral chips in the present embodiment, after the system is powered on, peripheral chip is initialized, and whether the initialization is successful is detected, if yes, the system enters a normal operation state, and if not, necessary protection is adopted. The normal operation state of the system means that: if the system is an executor controller such as a BMS, a DC-DC, a motor controller and the like, after entering the state, the system CAN send a high-voltage connection permission signal to the whole vehicle controller through the CAN, so that the system is characterized by normal functions and enters a state of waiting for high-voltage connection; if the system is a VCU whole vehicle controller, a functional logic judgment is carried out to judge whether the high-voltage connection of a plurality of high-voltage related actuators is allowed, if so, a relay high-voltage connection instruction is sent to the BMS, the whole vehicle enters a high-voltage state, and then the vehicle can normally run (e.g. a motor can send torque according to the VCU instruction); if not, the VCU is protected according to the protection strategy of the VCU.
When initializing the peripheral chip, in order to determine whether there is a fault in initializing the peripheral chip, an initialization write value, that is, a value that is read back from a register value of the peripheral chip when initializing the peripheral chip, may be obtained.
Further, step S10 specifically includes:
When initializing a peripheral chip, resetting the numerical values of a write-in frequency counter and a fault counter;
Acquiring a second count value of the write-in frequency counter;
detecting whether the second count value is larger than a preset count value;
when the second count value is smaller than or equal to the preset count value, calling an initialization function of the peripheral chip;
Configuring a register of a peripheral chip through the initialization function;
And after waiting for the preset time, reading back the register value of the peripheral chip to obtain the initialized writing value of the peripheral chip.
It can be understood that when the peripheral chip is initialized, the system is powered on, enters an initialization stage, carries out zero clearing operation of the write-in frequency counter and the fault counter, acquires the count value of the write-in frequency counter after zero clearing, namely, the second count value, detects whether the count value of the write-in counter is larger than the preset count value, and the preset count value can be set to be 2, 3 and the like, and can be set according to specific conditions, so that proper values are selected, if the setting is too small, the fault is easy to misreport, the system is too sensitive, the fault tolerance is low, if the setting is too large, the fault detection is slow, the protection is not timely, and the system safety is poor.
When the second counter value is smaller than the preset counter value, the peripheral chip can be initialized, so that the singlechip invokes an initialization function of the peripheral chip through communication modes such as SPI/I2C/UART, and accordingly, a target value writing operation of the peripheral chip initialization is executed through the initialization function, a chip function related register is configured, the value of the writing frequency counter is added with 1, and after waiting for preset time, the peripheral chip register value is read back, so that a peripheral chip initialization writing value is obtained.
The preset time can be set to 3s, 5s, etc., and is directly related to the selected communication mode and the peripheral chip because the transmission of the communication data requires time.
The process of initializing the peripheral chip may be as follows:
void INITxxxx_16bits(void)
{
//initialize main logic
RegisterInitial(REG1,A)；
RegisterInitial(REG2,B)；
RegisterInitial(REG3,C)；
…
}
Where REG1\2\3 represents the address of the different register, A\B\C represents the value to be written into the register, and the configuration of these values represents different functions.
In a specific implementation, the second count value may be greater than the preset count value, so after the step of detecting whether the second count value is greater than the preset count value, the method further includes: when the second count value is larger than the preset count value, a first count value of a fault counter is obtained; detecting whether the first count value is larger than the preset count value or not to obtain a detection result; and determining an initialization result of the peripheral chip according to the detection result.
When the second count value is greater than the preset count value, the first count value of the fault counter is obtained, and the first count value is the count value of the fault counter, so that whether the first count value is greater than the preset count value is detected, a detection result is obtained, and the initialization result of the peripheral chip is determined according to the detection result.
The detection result may be that the first count value is greater than the preset count value or the first count value is less than or equal to the preset count value, and the initialization result includes successful or failed initialization of the peripheral chip.
Step S20: and comparing the initialized writing value with a preset readback value to obtain a comparison result.
It should be noted that, the initialized writing value may be compared with the preset reading value, so as to obtain a comparison result.
In a specific implementation, the preset readback value is a target value that should be written when the peripheral chip is initialized, if the initialized write-in value is not equal to the preset readback value, the count value of the fault counter is increased by 1, and the step of detecting whether the count value of the write-in counter is greater than the preset count value is returned.
If the initialization writing value is equal to the preset readback value, whether the peripheral chip is initialized successfully is further determined.
Step S30: and determining an initialization result according to the comparison result.
It should be noted that, the initialization result of the peripheral chip may be determined according to the comparison result.
The initialization result comprises the success or failure of initialization, and the step of determining the initialization result according to the comparison result comprises the following steps: when the comparison result is that the initialization writing value is equal to the preset readback value, a first count value of a fault counter is obtained; determining whether the first count value is larger than a preset count value; when the first count value is larger than the preset count value, determining that the initialization result is an initialization failure; and when the first count value is smaller than or equal to the preset count value, determining that the initialization result is successful in initialization.
It should be noted that, when the comparison result is that the initialized writing value is equal to the preset reading value, the first count value of the fault counter may be obtained, so as to compare the first count value with the preset count value, and determine whether the first count value is greater than the preset count value.
In a specific implementation, if the first count value of the fault counter is greater than the preset count value, the initialization result is determined to be the initialization failure, and if the first count value of the fault counter is less than or equal to the preset count value, the initialization result is determined to be the initialization success.
Step S40: and finishing the initialization of the peripheral chip according to the initialization result.
In a specific implementation, the initialization of the peripheral chip can be completed according to the initialization result of the peripheral chip, for example, when the initialization fails, corresponding protection measures are taken, and the initialization stage is exited.
In the embodiment, when initializing the peripheral chip, an initialization writing value is obtained; comparing the initialized writing value with a preset readback value to obtain a comparison result; determining an initialization result according to the comparison result; and the initialization of the peripheral chip is completed according to the initialization result, and the initialization fault can be conveniently and efficiently identified, so that the peripheral chip is timely protected in a targeted manner according to the detection result, and the initialization effect of the peripheral chip is improved.
Referring to fig. 5, fig. 5 is a flowchart illustrating a peripheral chip initializing method according to a second embodiment of the present invention.
Based on the first embodiment, the peripheral chip initializing method in this embodiment includes, at step S40:
Step S401: and when the initialization result is the initialization failure, storing the failure fault information of the peripheral chip initialization failure into a preset memory, and generating a protection strategy.
It should be understood that when the initialization result is the initialization failure, the data may be stored in the preset memory, that is, the peripheral chip initialization failure fault information is stored in the preset memory, so as to facilitate the tracing of the initialization failure and generate the protection policy.
It should be noted that, to ensure the security of the system, a corresponding protection policy may be generated after the initialization failure of the peripheral chip, so as to take targeted protection measures, thereby implementing the system function most efficiently and safely.
The preset Memory may be a ROM (Read-Only Memory) or a RAM (Random Access Memory ), and may be uniformly stored to the ROM before power-down by storing the peripheral chip initialization failure fault information to a RAM area that specifically stores the fault code when the initialization fails. And fault information can be uploaded to the cloud through remote monitoring, so that big data analysis is facilitated.
Step S402: and executing corresponding protection on the peripheral chip through the protection strategy.
It should be noted that, the corresponding protection may be performed on the peripheral chip according to the corresponding protection policy.
Step S403: and generating initialization failure information, exiting the initialization of the peripheral chip, and resetting the values of the write-in frequency counter and the fault counter.
In specific implementation, after the corresponding protection measures are executed, initialization failure information is generated, the initialization of the peripheral chip is exited, the initialization failure is performed, the values of the write-in frequency counter and the fault counter are cleared, and the next initialization of the peripheral chip is facilitated.
In this embodiment, when the initialization result is an initialization failure, the peripheral chip initialization failure fault information is stored into a preset memory, and a protection policy is generated; executing corresponding protection on the peripheral chip through the protection strategy; generating initialization failure information, exiting the initialization of the peripheral chip, resetting the values of the write-in frequency counter and the fault counter, and storing data into a preset memory when a fault occurs, so that the tracing is convenient, corresponding protection is adopted, and the initialization safety is improved.
Referring to fig. 6, fig. 6 is a flowchart illustrating a third embodiment of a peripheral chip initializing method according to the present invention.
Based on the above second embodiment, the peripheral chip initializing method of the present embodiment includes, in the step S401:
step S4011: and when the initialization result is the initialization failure, storing the peripheral chip initialization failure fault information into a preset memory.
When the initialization result is the initialization failure, the peripheral chip initialization failure fault information is stored in the preset memory, so that the follow-up fault tracing is facilitated.
Step S4012: and obtaining the types of the peripheral chips.
The protection measures can be formulated according to the types of the single chip controllers and the types of the peripheral chips with different functions, so that the types of the peripheral chips can be obtained.
In an implementation, for example, the peripheral chips are communication chips, power management chips, and other peripheral chips may be included.
Step S4013: and generating a corresponding protection strategy according to the category.
In a specific implementation, the corresponding protection policy may be generated according to the type of the peripheral chip.
For example, the singlechip controller is a motor controller, and different protection strategies are generated according to the types of peripheral chips as shown in the following table 1:
TABLE 1
When the peripheral chip is a power management chip, the corresponding protection strategy is to record fault codes to ROM so as to facilitate the subsequent problem investigation, and send a motor system fault lamp lighting request to an instrument through a CAN bus to prompt a user; meanwhile, a request which is not allowed to be connected with the high voltage is sent to the PDCU so as to limit the high voltage on the whole vehicle and avoid further deterioration of the fault.
In the embodiment, when the initialization result is the initialization failure, the peripheral chip initialization failure fault is stored into a preset memory; acquiring the types of the peripheral chips; and generating a corresponding protection strategy according to the types, and adopting targeted protection according to different peripheral chips to improve the safety of the system.

It should be noted that, when the initialization result is that the initialization is successful, the initialization stage may be exited.
Step S402': and resetting the numerical values of the write-in times counter and the fault counter to finish the initialization of the peripheral chip.
It will be appreciated that the values of the write-in number counter and the failure counter may be cleared to facilitate the next initialization or initialization of different kinds of peripheral chips.

As shown in fig. 9, fig. 9 is a schematic diagram of still another overall flow of the peripheral chip initializing method, after the system is powered on, entering an initializing stage, resetting the write-in number counter and the fault counter, judging whether the value of the write-in number counter is greater than 2 (calibratable), if yes, judging whether the value of the fault counter is greater than 2, if the value of the write-in number counter is not greater than 2, executing peripheral chip initializing target value writing operation, adding 1 to the value of the write-in number counter, readbacking the value of the peripheral chip register, comparing whether the initialized write-in value is consistent with the readback value, if the write-in value is not equal to the readback value, adding 1 to the value of the fault counter, and returning to the step of judging whether the value of the write-in number counter is greater than 2, if the write-in value is equal to the readback value, judging whether the value of the fault counter is greater than 2, if the value of the fault counter is greater than 2, storing information of the peripheral chip initializing failure fault to a corresponding memory and executing corresponding protection, and exiting the initializing failure information, and exiting the initializing stage if the initializing failure information is equal to 2, and exiting the initializing stage is less than the initializing stage.
