In step S101, read control information is generated based on the acquired read-write control information, including: generating second timing information based on the acquired read-write control information; read control information is generated based on the second timing information.
In some embodiments, it takes a certain time to read and write to the programmable memory, and when the reading and writing do not reach the time of completion, the related information of reading or writing to the programmable memory is obtained, and the related information of reading or writing has distortion, for this reason, when the electronic device acquires the read-write control information, the electronic device starts timing and generates the second timing information, so that the distortion of the related information of reading or writing to the programmable memory is reduced through the generated second timing information, that is, the read control information is generated based on the second timing information; the second timing information is longer than the reading or writing time of the programmable memory, so that the occurrence of distortion of the related information which is read and written later is reduced; for example, the reading time of the programmable memory is 1us, in order to ensure the integrity of the read related information, under the condition that the generated first timing information is greater than 1us, reading control information is generated, and the related information read by the programmable memory is read; the writing time of the programmable memory is 6us, and in order to reduce the occurrence of distortion of the written related information, the reading control information is generated and the written related information of the programmable memory is read under the condition that the first timing information is generated to be larger than the writing time of the programmable memory by 6 us.
The method comprises the steps of monitoring the burning condition of the programmable memory, and only monitoring the writing condition of the programmable memory, so that when the electronic equipment acquires the read-write control information, the electronic equipment can firstly perform preliminary category analysis on the read-write control information, then generate second timing information, and generate the read control information based on the second timing information, namely generate the second timing information based on the acquired read-write control information, and specifically comprises the following steps: the electronic equipment judges whether the read-write control information is write control information or not; and under the condition that the read-write control information is the write control information, the electronic equipment generates a timing instruction and generates second timing information based on the timing instruction, wherein the second timing information is the time for recording the writing of the programmable memory.
In step S101, after acquiring the read-write control information corresponding to the bit in the programmable memory in real time, the method further includes: and generating a read-write control acquisition instruction under the condition that the read-write control information is the read-write control information, and continuously acquiring the read-write control information corresponding to the bit in the programmable memory based on the read-write control acquisition instruction.
In some embodiments, the obtained read-write control information is subjected to read-write control judgment, and under the condition that the read-write control information is the read-write control information, the condition shows that the bit in the programmable memory is only read operation and has no writing process at the moment, so that the monitoring and analysis of the subsequent writing operation of the current programmable memory are not needed, at the moment, the electronic equipment generates a read-write control acquisition instruction, and continuously monitors the reading or writing of the bit in the programmable memory based on the read-write control acquisition instruction, namely, continuously acquires the read-write control information corresponding to the bit in the programmable memory until the obtained read-write control information is the write control information, thereby realizing the automatic reading and writing monitoring of the programmable memory and improving the monitoring efficiency of the programmable memory; the bits corresponding to the read-write control information that is continuously acquired may be bits corresponding to the read-write control information that has already been acquired, or may be the remaining bits in the programmable memory.
In some embodiments, generating the read control information based on the second timing information specifically includes: judging whether the second timing information reaches a first preset duration or not; and generating read control information under the condition that the second timing information reaches the first preset duration.
In some embodiments, the electronic device sets a first preset time period that is longer than the time it takes for the programmable memory to write.
The second timing information is generated in real time and continuously changes, and considering that the time between the programming of different bits in the programmable memory is limited when the programming of the different bits is required, so that the second timing information generated by the electronic equipment for programming the single bit cannot be continuously increased, the electronic equipment sets a first preset duration, when the generated second timing information reaches the first preset duration, the integrity of the related information written in the programmable memory, which is read by the generated read control information, can be guaranteed, namely, when the electronic equipment generates the second timing information, the electronic equipment judges whether the second timing information reaches the first preset duration or not, when the second timing information reaches the first preset duration, the electronic equipment generates the read control information, namely, the electronic equipment generates the read control information, which can be read into the complete programmable memory, for subsequent reading of the related information written in the programmable memory, for example, the time for writing the programmable memory is 6us, the first preset duration is set to be larger than the first preset duration, when the electronic equipment writes the first preset duration is read by the programmable memory, the first preset duration is judged to be longer than the first preset duration, and the electronic equipment finishes the read of the programmable memory, and the read duration is finished when the electronic equipment finishes the read of the programmable memory.
In step S103, after analyzing the first timing information and the write operation information to obtain an analysis result, the method further includes: and under the condition that the analysis result shows that the first timing information reaches the second preset time length and the writing operation information is the correct operation information, acquiring the reading and writing control information corresponding to the rest bits except the bits corresponding to the reading and writing control information, and performing burning monitoring on the rest bits based on the reading and writing control information corresponding to the rest bits.
In some embodiments, the electronic device analyzes the first timing information and the writing operation information, where the obtained analysis result may be that the first timing information reaches a second preset duration, and the writing operation information is correct operation information, that is, the writing of the bits in the programmable memory is completed and the writing of the bits is correct, and because the programmable memory includes a plurality of bits, and each bit can be written, after the writing of the current and correct bits is completed, the electronic device does not exclude the continuous writing of the remaining bits, and therefore, when the analysis result is that the first timing information reaches the second preset duration, and the writing operation information is the correct operation information, the electronic device starts to obtain the writing control information corresponding to the remaining bits except the bits corresponding to the writing control information, and carries out the writing monitoring on the remaining bits based on the writing control information, so as to realize automatic monitoring of the writing of the programmable memory.
In step S103, the generating, based on the analysis result, the recording anomaly information and the invalidation control instruction that characterize the recording monitoring result includes: and generating burning abnormal information and an invalid control instruction representing a burning monitoring result under the condition that the analysis result is that the first timing information reaches the second preset time and the writing operation information is error operation information.
In some embodiments, the first timing information is a record of a time at which the related information written by the programmable memory was read.
And under the conditions that the analysis result obtained by the electronic equipment for analyzing the first timing information and the writing operation information is that the first timing information reaches the second preset time and the writing operation information is the error operation information, the electronic equipment indicates that the programming of the programmable memory is wrong at the moment, then the electronic equipment generates the abnormal programming information representing the programming monitoring result and sends the abnormal programming information to terminal equipment held by a technician so as to remind the technician of the burning mistake of the current programmable memory, and meanwhile, the electronic equipment generates an invalid control instruction representing the programming monitoring result and sends the invalid control instruction to the one-time programmable memory to control the one-time programmable memory to stop external access so as to facilitate the subsequent technician to inquire.
For example, the time for reading the related information written in the programmable memory is 1us, the time set by the second preset time length is 1us longer than the time for reading the related information written in the programmable memory, the correct writing operation information is high level 1, if the first timing information generated based on the writing operation information is longer than the time for reading the related information written in the programmable memory, the electronic device judges whether the writing operation information is wrong writing operation information, if the writing operation information is judged to be low level 0, the writing operation information is wrong writing operation information, and at this time, the electronic device generates burning abnormal information and invalid control instructions representing burning monitoring results.
Referring to fig. 2, after the programmable memory is powered on, read-write control information is acquired; and then, judging the type of the read-write control information, starting to count the write time and generating corresponding timing information when the read-write control information is the write control information, generating the read control information when the corresponding timing information reaches the corresponding preset time length, reading the write operation information based on the read control information, simultaneously starting to count the read time and generating the corresponding timing information, judging whether the write operation information is the wrong write operation information when the corresponding timing information reaches the corresponding preset time length, and generating an invalid control instruction and burning abnormal information representing a burning monitoring result when the write operation information is the wrong write operation information.
