Description

Technical Field

[0001] This application relates to the field of program writing technology, and in particular to a program writing control method, storage medium, program product, and program writing device. Background Technology

[0002] During the chip manufacturing process, preset binary code (such as firmware, operating system kernel or application, function settings, etc.) needs to be permanently or semi-permanently written into the chip's internal memory through program writing (also known as program burning) to set the chip's functions.

[0003] Currently, during the chip writing process, there is a lack of management and detection of electrical parameters (such as device power-on current, writing current, and writing voltage) during the program writing process. Therefore, it is not easy to detect abnormalities in the chip during the program writing process, which affects the chip yield and the efficiency of program writing to the chip. Summary of the Invention

[0004] This application provides a method for controlling program writing, a storage medium, a program product, and a program writing device. This ensures the accuracy of the program writing process and improves the yield rate of the chip.

[0005] In a first aspect, embodiments of this application provide a program writing control method applied to a program writing device, the program writing device including a program writer and a monitor, the method including: the program writer outputting a first level signal to a chip, the first level signal being used to write first data to the chip; the monitor detecting a first level value corresponding to the first level signal; the monitor comparing the first level value with a standard level range corresponding to the first data, and if the first level value exceeds the standard level range, controlling the program writer to stop writing data to the chip.

[0006] In some embodiments of this application, the monitor can detect the first level value of the first level signal output by the programmer to the chip. The monitor can then determine whether the first level value is within the standard level range corresponding to the first data to ensure the accuracy of the level signal currently output by the programmer to the chip, thereby guaranteeing the accuracy of the program writing device writing the program to the chip.

[0007] In one possible implementation of the first aspect described above, the program writer outputs an electrical signal to the chip based on the arrangement order of multiple program data, wherein the multiple program data includes first data and the electrical signal includes a first level signal. The monitor stores multiple program data, and the monitor compares the first level value with a standard level range corresponding to the first data, including: the monitor determining a first timing sequence of the first level signal in the electrical signal; the monitor determining the first data corresponding to the first level data from the multiple program data based on the first timing sequence; the monitor determining a standard level range corresponding to the first data, and comparing the first level value with the standard level range corresponding to the first data.

[0008] In one possible implementation of the first aspect described above, the monitor compares the first level value with a standard level range corresponding to the first data, including: when the programmer sends the first level data to the chip, the monitor obtains the first data from the programmer. The monitor determines the standard level range corresponding to the first data and compares the first level value with the standard level range corresponding to the first data.

[0009] In some embodiments of this application, when the programmer sends first-level data to the chip, it also sends first data corresponding to the first level to the monitor. This allows the monitor to determine the standard level range corresponding to the currently obtained first-level value, thereby determining whether the first-level value exceeds the standard level range. In this way, the monitor can determine whether the first-level value of the first-level data exceeds the standard level range as soon as the programmer finishes outputting the first-level data, thus improving the detection effect.

[0010] In one possible implementation of the first aspect described above, controlling the programmer to stop writing data to the chip if the first level value exceeds the standard level range includes: if the first level value exceeds the standard level range, the monitor determines that an anomaly has occurred in the programmer's writing process to the chip. If the number of anomalies in the programmer's writing process to the chip exceeds a first preset number, the programmer is controlled to stop writing data to the chip.

[0011] In some embodiments of this application, if the monitor detects an abnormal first voltage level, it will not immediately control the programmer to stop writing programs to the chip. The programmer can rewrite programs to the chip. The monitor will only control the programmer to stop writing programs to the chip when it detects that the number of abnormal program writing attempts by the programmer exceeds a first preset number. This avoids the impact of occasional electrical signal anomalies caused by external influences on program writing.

[0012] In one possible implementation of the first aspect described above, if the number of times the program writer encounters an error while writing the program to the chip is less than or equal to a first preset number, the program writer is controlled to rewrite the program to the chip.

[0013] In one possible implementation of the first aspect described above, the monitor acquires first current data of the programmer before the programmer outputs an electrical signal to the chip. Controlling the programmer to stop writing data to the chip further includes: if the first current data exceeds a first current range, the monitor determines that the first current data is abnormal; if the number of times the first current data is abnormal exceeds a second preset number, the monitor controls the programmer to stop writing data to the chip.

[0014] In some embodiments of this application, before the programmer connects to the chip and writes a program to the chip, the monitor can also acquire first current data and detect whether the first current data exceeds a first current range. This ensures that the connection between the chip and the programmer is normal and that the chip itself is not abnormal (e.g., short circuit or open circuit), thereby avoiding the problem of damage to the chip writing device due to abnormalities in the chip itself when the programmer writes a program to the chip.

[0015] In one possible implementation of the first aspect described above, during the process of the programmer outputting an electrical signal to the chip, the monitor acquires the second current data of the programmer. The programmer stopping writing programs to the chip further includes: if the second current data exceeds a second current range, the monitor determines that the second current data is abnormal; if the number of times the second current data is abnormal exceeds a third preset number, the programmer stops writing programs to the chip.

[0016] In some embodiments of this application, during the process of the programmer writing a program to the chip, the monitor can also acquire the second current data output by the programmer to the chip and determine whether the second current data exceeds the second current range. This determines whether the second current data is abnormal, ensuring that the current is normal when the programmer writes the program to the chip, further guaranteeing the accuracy of the programmer writing the program to the chip.

[0017] Secondly, this application provides a program writing apparatus, comprising: a monitor and a program writer as described in the first aspect (i.e., any possible implementation of the method provided in the first aspect); a memory for storing instructions; and at least one processor for executing the instructions to cause the device to implement the first aspect and any possible implementation of the method provided in the first aspect. The beneficial effects achievable by the second aspect can be referred to the beneficial effects of the method provided in any embodiment of the first aspect, and will not be repeated here.

[0018] Thirdly, this application provides a computer storage medium storing instructions that, when executed by a device, cause a computer to implement the methods provided in the first aspect and any possible implementation of the first aspect. The beneficial effects achievable in this third aspect can be referenced to the beneficial effects of the methods provided in any embodiment of the first aspect, and will not be repeated here.

[0019] Fourthly, this application provides a computer program product that stores instructions that, when executed on a device, cause the device to implement the methods provided in the first aspect and any possible implementation of the first aspect. The beneficial effects achievable in the fourth aspect can be found in the beneficial effects of the methods provided in any embodiment of the first aspect, and will not be repeated here.

[0028] The illustrative embodiments of this application include, but are not limited to, a program writing control method, a storage medium, a program product, and a program writing device.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] As shown in the background art, during the process of writing programs to a chip, there is a lack of management and detection of electrical parameters during the program writing process. Therefore, it is not easy to detect abnormalities in the chip during the program writing process, which affects the yield of the chip and the efficiency of program writing to the chip.

[0031] The following describes the process of writing a program using a program writer.

[0032] For example, Figure 1 A schematic diagram of a programmer writing programs to a chip is shown.

[0033] Reference Figure 1 In some embodiments, when programming the chip 10, the program writer 20 can be connected to the chip 10 via the data interface 30. The program writer 20 mainly consists of a power supply system, an encoder, and a decoder. The encoder compiles the software instruction code into electrical pulses and sends them to the chip 10, enabling data reading and writing to the memory within the chip 10. The decoder decodes the interactive signals fed back from the chip and reads the signals via software.

[0034] It is understandable that the current program writer 20 only provides the encoder and decoder necessary for program writing, which can only meet the basic program writing needs. However, it lacks the monitoring and management functions for program writing electrical parameters (such as the device's power-on current, writing current, and writing voltage), and cannot actively detect potential problems in the program writing process, thus failing to ensure the reliability of program writing.

[0035] In some embodiments of this application, a program can be written to the chip using a program writing device. The program writing device may include a program writer and a monitor. The program writer writes program data to the chip by sending electrical signals of different levels.

[0036] To address the aforementioned issues, this application provides a program writing control method. A program writer outputs a first-level signal to the chip, which is used to write first data to the chip. A monitor detects the first-level value corresponding to the first-level signal. The monitor compares the first-level value with a standard level range corresponding to the first data. If the first-level value exceeds the standard level range, the monitor controls the program writer to stop writing data to the chip.

[0037] Using the above method, the monitor can detect the first level value of the first level signal output by the programmer to the chip. The monitor can then determine whether the first level value is within the standard level range corresponding to the first data to ensure the accuracy of the level signal currently output by the programmer to the chip, thereby guaranteeing the accuracy of the program writing device writing the program to the chip.

[0038] The following describes the write program control method in the embodiments of this application.

[0039] For example, Figure 2 According to some embodiments of this application, a flowchart of an implementation method for program control is shown.

[0040] like Figure 2 As shown, the process includes:

[0041] S201, the programmer outputs a first level signal to the chip, which is used to write the first data to the chip.

[0042] In some embodiments of this application, when writing a program to the chip, the chip's pins can be electrically connected to the corresponding interface on the programmer. Then, after the monitor determines that there is no abnormality in the current during chip connection, the programmer can input the electrical signal corresponding to the program data to be written to the chip.

[0043] For example, Figure 3A According to some embodiments of this application, a schematic diagram of a program writing device is shown.

[0044] Reference Figure 3A In some embodiments of this application, the program writing device includes a program writer, a monitor, a status indicator, a chip interface, and a power supply device.

[0045] The power supply unit is electrically connected to the programmer, monitor, status indicator, and chip interface, and provides power to the programmer, monitor, status indicator, and chip interface.

[0046] The programmer can be electrically connected to a monitor, allowing the monitor to acquire the electrical signals output by the programmer to the chip. The monitor is also electrically connected to a status indicator light, enabling it to issue an alarm (e.g., flashing red) when an anomaly is detected (e.g., abnormal electrical signal or current), or to provide a notification (e.g., emitting green light) after the programming process is complete. Furthermore, the monitor is electrically connected to the chip interface; that is, a monitor connects the programmer to the chip interface, allowing the monitor to acquire and analyze the electrical signals sent by the programmer to the chip interface to determine if any anomalies exist.

[0047] In some embodiments of this application, program data is stored in binary form, i.e., a sequence of 0s and 1s. The program writer can convert the binary data into electrical signals and output them to the chip through a chip interface; for example, a high level represents 1, and a low level represents 0. In some embodiments of this application, the first level signal input by the program writer to the chip can be the level signal corresponding to the first data in the program data. That is, the electrical signal output by the program writer to the chip includes the first level signal, thus allowing the program writer to output the first data in the program data to the chip.

[0048] In the embodiments of this application, the chip interface can integrate interfaces for connecting chips of different specifications to a programmer. For example, taking a chassis position sensor (CPS) as an example, CPS can be divided into three main categories based on the pin interface type: analog signal interface, pulse width modulation (PWM) signal interface, and PSI5 electronic signal interface. Taking the analog signal and PWM signal interfaces as examples, the analog signal and PWM signal interface includes three pins: an output pin (OUT), a ground pin (GND), and a power supply pin (VDD). The power supply pin and ground pin are used for power supply, and the output pin is used for signal output. The PSI5 electronic signal interface includes two pins: a ground pin (GND) and a power supply pin (VDD), which serve as both power supply pins and signal input / output pins. In the embodiments of this application, the chip interface can include a three-pin interface: an output pin interface, a ground pin interface, and a power supply pin interface. The ground pin interface and the power supply pin interface can be connected to the ground pin and power supply pin of the CPS. When connecting different types of CPS, the ground pin interface and the power supply pin interface can be multiplexed. In other words, when connecting a CPS of analog signal and pulse width modulation signal types, a three-pin interface can be used; when connecting a CPS of PSI5 electronic signal type, a ground pin interface and a power supply pin interface can be used. It is understood that the chip interface can also integrate or use more or fewer interfaces depending on the type of chip; the embodiments of this application do not limit the chip interface.

[0049] In some embodiments of this application, before the programmer outputs an electrical signal to the chip, the chip is in a reset state, its internal circuitry is not fully activated, and its load characteristics are similar to pure resistance, with a small and stable current. Therefore, in some embodiments of this application, before the programmer outputs an electrical signal to the chip, the monitor can also acquire the current data (hereinafter referred to as the first current data) when the chip is connected to the programmer. At this time, the monitor can determine whether the first current data is abnormal to determine whether the connection between the chip and the programmer is normal or whether the chip is normal. It is understood that when the chip is electrically connected to the programmer but before the program is written, the first current data provided by the programmer to the chip is small. The monitor can determine whether the chip is correctly connected and whether the chip is abnormal based on whether the first current is within a certain range. For example, if the first current data exceeds the first current range, the monitor can determine that the first current data is abnormal.

[0050] For example, if the first current data is less than the first current range, it may indicate an open circuit inside the chip or a misconnection between the chip and the programmer. The monitor can control the status indicator to flash red to alert the operator of the abnormal connection between the chip and the programmer. The operator can then reconnect the chip to the programmer, and the monitor will re-check whether the first current data exceeds the first current range to reconfirm whether the first current data is abnormal.

[0051] Alternatively, if the first current data exceeds the first current range, it indicates a short circuit inside the chip or a misconnection between the chip and the programmer. The monitor can then control the status indicator light to flash red to alert the operator of the abnormal connection between the chip and the programmer. The operator can then reconnect the chip to the programmer, and the monitor will re-check whether the first current data exceeds the first current range to reconfirm whether the first current data is abnormal.

[0052] In other words, in the embodiments of this application, after the monitor detects an abnormality in the first current data, it will not immediately stop programming the chip. Instead, it will record the number of abnormalities in the first current data. If the number of abnormalities in the first current data is greater than or equal to the second preset number, the controller will control the programmer to stop writing program data to the chip, report an error, and save the log of program writing failure.

[0053] In some embodiments of this application, the first current range can be 10 microamps to 40 microamps, and the second preset number of times can be 2 to 5 times, for example, 2 times, 3 times, 4 times, or 5 times. It is understood that the first current range and the second preset number of times can be set according to the chip model or the model of the programmer. The embodiments of this application do not limit the first current range and the second preset number of times.

[0054] S202, the monitor detects the first level value corresponding to the first level signal.

[0055] In some embodiments of this application, the monitor can detect the first level signal output by the programmer to the chip. After acquiring the first level signal, the monitor can determine the first level value corresponding to the first level signal. It can be understood that since the programmer converts the binary data corresponding to the program data into an electrical signal and outputs it to the chip through the chip interface, the first level value can be either high or low.

[0056] S203, the monitor compares the first level value with the standard level range corresponding to the first data. If the first level value exceeds the standard level range, the controller stops writing data to the chip.

[0057] In some embodiments of this application, during the process of the programmer writing a program to the chip, an electrical signal abnormality may occur, causing the voltage level corresponding to the first data to be written to differ from the voltage level actually written to the chip by the programmer. Therefore, after the monitor determines the first voltage level, it can compare the first voltage level with the standard voltage level range corresponding to the first data. If the first voltage level exceeds the standard voltage level range, it indicates that the programmer is malfunctioning in writing the program to the chip, and the controller can control the programmer to stop writing program data to the chip.

[0058] In some embodiments of this application, the programmer outputs electrical signals to the chip based on the arrangement order of multiple program data. The multiple program data includes first data, and the electrical signals include a first level signal. For example, the multiple program data could be 10110110. Taking the program data "0" at the 8th position as the first data, when the programmer writes the first data "0", the input level to the chip should be low. In the embodiments of this application, the standard level range corresponding to a high level can be 4.7V to 5.3V, and the standard level range corresponding to a low level is 0V to 0.3V. That is, the first level value must be between 0V and 0.3V to confirm that the first level signal output by the programmer to the chip is correct.

[0059] In embodiments of this application, the monitor can store multiple program data, for example, storing "10110110". The monitor can then determine a first timing sequence of the first level signal within the electrical signal. Based on this first timing sequence, the monitor can then determine the first data corresponding to the first level data from the stored multiple program data.

[0060] For example, refer to Figure 3B , Figure 3B According to some embodiments of this application, a schematic diagram of the timing of an electrical signal is shown.

[0061] exist Figure 3B In this circuit, the clock period of each electrical signal level is T. If the first level signal detected by the monitor has a first timing sequence of 7T to 8T, then the monitor can determine the first timing sequence as 8 (where timing sequence 1 corresponds to the period from 0 to T, timing sequence 2 corresponds to the period from T to 2T, timing sequence 3 corresponds to the period from 2T to 3T, and so on). Then, the controller determines the data "0" at the 8th position from the stored program data "10110110" as the first data.

[0062] The monitor can then determine the standard level range corresponding to the first data and compare the first level value with the standard level range corresponding to the first data. For example, continuing to refer to... Figure 3A After determining that the first data is "0", the monitor can determine that "0" corresponds to a low level, and the standard level range for a low level is 0V to 0.3V. The monitor can compare the first level value of 0V with the standard level range. It can be understood that if the first level value is within the standard level range, then the first level signal output by the programmer to the chip can be determined to be correct. It can also be understood that in some embodiments, when the monitor determines that the first data is 1, the corresponding standard level range is 4.7V to 5.3V.

[0063] In some embodiments, the monitor can also acquire electrical signals over a period of time, and determine whether there are any levels exceeding the standard level range during that period based on the level values ​​of the electrical signals and the corresponding program data, thereby determining whether the electrical signals output by the program writer to the chip are abnormal.

[0064] In other embodiments, when the programmer sends first-level data to the chip, the monitor obtains the first data from the programmer. Then, the monitor determines the standard level range corresponding to the first data and compares the first level value with the standard level range corresponding to the first data. That is, the monitor does not need to pre-store multiple program data sets; when the programmer outputs a first-level signal to the chip, it can send the first data to the monitor. Based on the first data, the monitor can determine the standard level range corresponding to the first level value of the currently detected first-level signal and determine whether the first level value exceeds the standard level range. In this way, the monitor can determine in real time whether the programmer is outputting an error when outputting electrical signals to the chip, so that the monitor can control the programmer in a timely manner.

[0065] It is understood that, for different chips and different programmers, the standard level ranges for high and low levels may differ from those in the above embodiments, and the above embodiments do not limit the standard level range.

[0066] In some embodiments of this application, if the first voltage level exceeds the standard voltage level range, the monitor determines that an error has occurred during the program writing process from the program writer to the chip. In this case, the monitor can control the status indicator light to issue an alarm. If the number of errors during the program writing process is less than or equal to a first preset number, the monitor can control the program writer to rewrite the program to the chip. If the monitor detects that the number of errors during the program writing process is greater than the first preset number, the monitor can stop writing the program to the chip and output a log indicating a writing failure.

[0067] In some embodiments of this application, while the programmer is outputting electrical signals to the chip, the monitor can also acquire second current data from the programmer. Furthermore, the monitor can detect whether the second current data exceeds a second current range. In these embodiments, when the programmer outputs data to the chip, the second current data is only used to provide energy and not to transmit data; therefore, there is only one second current range, and the monitor only needs to determine whether the second current data exceeds the second current range. When the second current data exceeds the second current range, the monitor determines that the current of the programmer writing multiple program data to the chip is abnormal. The monitor can control the status indicator light to issue an alarm, and if the number of abnormal second current data occurrences is less than or equal to a third preset number, the monitor controls the programmer to output electrical signals to the chip again. If the number of abnormal second current data occurrences is greater than the third preset number, the monitor can control the programmer to stop writing programs to the chip and save a log of the writing failure.

[0068] Understandably, through the above solution, the monitor can detect whether the first current data is abnormal when the programmer connects to the chip, and whether the output electrical signal and the second current data are abnormal when the programmer outputs an electrical signal to the chip. This can more comprehensively and accurately ensure the accuracy of the program data written by the programmer to the chip, thus guaranteeing the chip's yield. Furthermore, it can also prevent damage to the programming device or chip due to abnormal voltage or current.

[0069] The following describes the process of writing program data to the chip using a program writing device.

[0070] For example, Figure 4 According to some embodiments of this application, a flowchart illustrating the implementation of a program writing device writing program data to a chip is shown.

[0113] For example, in some embodiments of this application, if the monitor detects an abnormality in the second current data, the program writing device can issue an alarm prompt. The alarm prompting process can refer to the process of S203 described above, and the monitor can record the number of abnormalities in the second current data by one.

[0114] S416, the monitor determines whether the number of abnormal current data exceeds the third preset number.

[0115] In the embodiments of this application, after the monitor determines that the second current data is abnormal, it can determine whether the number of abnormal times of the second current data exceeds a third preset number.

[0116] If the judgment result is yes, then execute S418, the program write failed, and the failure log is saved.

[0117] If the judgment result is negative, then S405 is executed, and the program writer outputs an electrical signal to the CPS.

[0118] S417, the program writing device completes program writing.

[0119] S418, program write failed, save the failure log.

[0120] It is understandable that through the above process, the program writing device can write program data to the CPS more accurately, and can stop writing program data to the CPS when the first current data or the second current data is abnormal, so as to avoid damage to the program writing device or the CPS due to abnormal current.

[0121] The software system of the program writing device in the embodiments of this application is described below.

[0122] For example, Figure 5 According to some embodiments of this application, a program writing system is shown.

[0123] Reference Figure 5 The program writing system includes a program setting module, a monitoring, checking and writing module, and a template and saving module.

[0124] In the embodiments of this application, taking the writing of data to a CPS as an example, the program setting module can set the magnetic field angle and linearity, electrical functions, and production information for the CPS. The setting process can refer to the CPS datasheet. The magnetic field angle and linearity settings vary depending on the sample, and each CPS has a unique setting. The electrical function settings and production information settings are defined by the vehicle model corresponding to the CPS and can be uniformly set using templates.

[0125] The monitoring, checking, and writing module can perform program register checks, electrical parameter monitoring and checks, and program writing.

[0126] The program register check unit can update the register information corresponding to the program settings in real time. Before writing the program, it checks the register contents to prevent discrepancies between the set values ​​and the register contents due to misoperation or magnetic field interference. This avoids erroneous program write values ​​affecting CPS linearity settings and ultimately causing CPS malfunction. Electrical parameter monitoring and checking can be referenced as described above. Figure 2 as well as Figure 4 The process is shown below.

[0127] The template and save module can save program setting templates. During the initial program writing process, operators need to set the electrical functions and production information of the CPS and save the settings. When the program writing is performed again, the template can be called to quickly execute the settings. This saves resetting time and avoids errors. In this way, different sensor program writing data templates can be set for different signal types, and the data can be saved after the program writing is completed.

[0128] The following describes the process of the program writing device writing a program to the CPS in the embodiments of this application.

[0129] For example, Figure 6 According to some embodiments of this application, a flowchart illustrating the implementation of a program writing device writing a program to a CPS is shown.

[0130] It is understandable that the execution entity for each of the following processes is the program writing device.

[0131] like Figure 6 As shown, the process includes:

[0132] S601, connected to CPS, program writing device enabled.

[0133] In some embodiments of this application, the program writing device is connected to the CPS and enters an enabled state.

[0134] S602, reads the magnetic field angle of CPS.

[0135] In some embodiments of this application, after the program writes the device connection number CPS, it can read the magnetic field angle of the CPS to determine the initial magnetic field angle of the CPS, and then set the magnetic field angle of the CPS to set the working state of the CPS.

[0136] S603, determine whether the magnetic field angle of CPS has been read.

[0137] In some embodiments of this application, the program writing device can determine whether the magnetic field angle of the CPS has been read.

[0138] If the judgment result is yes, then execute S604 to calculate the sensor linearity setting.

[0139] If the judgment result is negative, then S601 is executed, the CPS is connected, and the program writing device is enabled.

[0140] It is understood that if the program writing device fails to complete the magnetic field angle of the CPS, the CPS may not be properly connected to the program writing device. Therefore, S601 can be re-executed to reconnect the CPS. It is understood that in some embodiments, if the magnetic field angle of the CPS cannot be read after multiple reconnections, the CPS may be damaged, and the program writing to the CPS can be terminated.

[0141] S604, calculates the linear setting of the sensor.

[0142] In some embodiments of this application, after determining the magnetic field angle of the CPS, the program writing device can calculate the linear setting of the CPS sensor. The linear setting of the sensor can be determined by the above... Figure 5 The program setting module in the embodiment is executed. The linear setting is used to determine the linearity of the CPS sensor's output data.

[0143] S605, determine whether a template exists for the sensor linear setting.

[0144] In some embodiments of this application, the program writing device can determine whether a template exists in the sensor linear setting.

[0145] If the judgment result is yes, then execute S606 and call the template.

[0146] If the judgment result is negative, then execute S607 to configure the sensor's functions.

[0147] S606, call template.

[0148] In some embodiments of this application, if the program writing device stores the linear setting template of the current CPS sensor, the program writing device can directly call the template, then generate the sensor's program data, and then execute S611 to update the register information.

[0149] S607 is used to configure the sensor's functions.

[0150] In some embodiments of this application, if the program writing device does not store the template of the current CPS sensor, the operator needs to set the function of the sensor through the program writing device to generate the program data of the CPS sensor.

[0151] S608 is used to set the sensor's production information.

[0152] In some embodiments of this application, it is also necessary to write data such as the production information of the CPS sensor into the CPS sensor. Therefore, it is also necessary for staff to set the sensor's production information based on the program writing device.

[0153] S609, determine whether to save the template.

[0154] In some embodiments of this application, after setting the current CPS sensor's functions and production information, the staff can also determine whether to save the template.

[0155] If the judgment result is yes, for example, if the staff triggers the instruction to save the template, then execute S610 to save the template.

[0156] If the result is negative, for example, if no worker is detected to trigger the instruction to save the template, then execute S611 to update the register information.

[0157] S610, save template.

[0158] S611, update register information.

[0159] In the embodiments of this application, after the program writing device has determined the CPS settings, it can store the CPS program data in the register to update the register message.

[0160] S612 determines whether the sensor linear design is consistent with the register information.

[0161] In some embodiments of this application, to ensure the accuracy of the program writing device writing program data to the CPS, the program writing device can also determine whether the linear design of the sensor is consistent with the register information.

[0162] If the judgment result is yes, then execute S613 to start writing the program.

[0163] If the judgment result is negative, then execute S602 to read the magnetic field angle of CPS.

[0164] Understandably, if the judgment result is negative, it indicates that the linear design of the sensor is inconsistent with the stored register information. In this case, it is necessary to re-acquire the magnetic field angle of the CPS and re-set the linearity of the CPS to redetermine the register information in the program writing device. This is to ensure the accuracy of the program data stored in the register information.

[0165] S613, begin writing the program.

[0166] In some embodiments of this application, if the program writing device determines that the linear design of the sensor is consistent with the register information, it can begin writing program data to the CPS.

[0167] S614, determine if the electrical parameters are abnormal.

[0168] In the embodiments of this application, the program writing device can also determine whether the electrical parameters are abnormal, and the determination process can refer to the above. Figure 2 Or the above Figure 4The process in the middle.

[0169] If the result is negative, then execute S615 to determine whether the program was successfully written.

[0170] If the judgment result is yes, then execute S617, the program write failed, and the failure log is saved.

[0171] S615 determines whether the program has been successfully written.

[0172] In some embodiments of this application, the program writing device can also determine whether the program data has been successfully written. For example, after successfully writing the program data, the CPS can send a message to the program writing device that the program has been successfully written.

[0173] If the judgment result is yes, then execute S616 to save the burning data and complete the program writing.

[0174] If the judgment result is negative, then execute S617, the program write failed, and the failure log is saved.

[0175] S616, saves the programming data, and completes the program writing.

[0176] Understandably, if the program writing device determines that the program has been successfully written to the CPS, the program writing device can save the burning data and complete the program writing.

[0177] S617, program write failed, save the failure log.

[0178] It is understood that in some embodiments of this application, if the program writing device detects an abnormal electrical parameter or determines that the program data has not been successfully written to the CPS, the current program writing can be considered a failure. The program writing device can save a failure log.

[0179] Through the above scheme, the program writing device can linearly set the CPS sensor by calling a template, thereby improving the efficiency and ensuring the accuracy of linear setting. Furthermore, the program writing device can also detect electrical parameter data (such as electrical signals, a first current signal, and a second current signal) during program writing to the CPS, thus ensuring the accuracy of the program writing.
