Description

Technical Field

[0001] The present disclosure belongs to the field of computer technology, and specifically relates to a signal processing method, device, processor, electronic control system, equipment and medium. Background Art

[0002] In the current automobile body control system, the interface between sensors and controllers is mainly based on the Controller Area Network (CAN), or CAN with flexible data rate (CAN-FD), Local Interconnect Network (LIN) and other buses. With the rapid development of smart cars, the vehicle electronic control system has become more and more complex, and the number of sensors and controllers has increased exponentially. There is an application scenario of signal routing in the vehicle electronic control system: some signals from multiple messages are recombined to generate new messages.

[0003] At present, when a new message is generated after some signals from multiple messages are recombined, each message is parsed separately to obtain each signal in each message, and then the signal is recombined according to the signal to be recombined. The above method can be easily implemented when the number of messages is small, but when the number of messages is large and there are multiple signals in each message, it is easy to cause confusion when the signals are recombined, thereby affecting the accuracy of the recombined message. Summary of the invention

When it is determined that the packet grouping operation on the first target signal is triggered, the signal value of the first target signal is obtained from the first storage position, and the first target signal is packetized based on the signal value to obtain the target message.

[0038] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0040] As described in the background technology section, there is a problem of low accuracy of packet assembly in the prior art. In order to solve the above problem, the embodiments of the present application provide a signal processing method, an apparatus, a processor, an electronic control system, a device and a medium. By parsing the first target message in at least one received message, the signal value of the first target signal in the first target message and the first storage position of the first target signal in the storage table are obtained, and then the signal value is stored in the first storage position. When it is determined that the packet assembly operation on the first target signal is triggered, the signal value of the first target signal is obtained from the first storage position, and the first target signal is packetized based on the signal value to obtain the target message. In this way, since the storage position of the first target signal is set in the storage table in advance, after parsing the first target message, the signal value of the first target signal in the first target message can be directly stored in the storage position, and then in the subsequent packet assembly, the signal value of the first target signal can be obtained from the storage position for packet assembly, so that confusion will not be caused by too many messages, thereby improving the accuracy of packet assembly.

[0041] Before introducing the signal processing method of the embodiment of the present application, a processor for implementing the signal processing method is first introduced. Figure 1 is a schematic diagram of the structure of a processor provided in an embodiment of the present application, such as Figure 1 As shown, the processor 100 may include a signal extraction module 110, a signal storage module 120 and a signal packaging module 130. The specific functions of the signal extraction module 110, the signal storage module 120 and the signal packaging module 130 will be introduced in detail in the following embodiments of the signal processing method.

[0042] In some embodiments of the present application, Figure 2 is a schematic diagram of the structure of another processor provided in an embodiment of the present application, such as Figure 2 As shown, Figure 2 As shown, the message is input from the signal extraction module, and then after the packetization is completed, the packetized message is output from the signal packetization module. Figure 2 The signal extraction module 110 includes a signal table, an invalidation table, etc.; the signal storage module includes a storage table, an initial value table, an invalidation mark, a filling table, a timer, etc.; the signal package module includes a message table and a periodic table, etc. The specific uses of each table will be introduced in detail in the following embodiments of the signal processing method.

[0043] In the prior art, when processing and packaging the signal, it is processed by the central processing unit (CPU). Figure 3 The communication architecture of the traditional vehicle electronic control system is to directly connect the CAN, CANFD, LIN and other buses to the CPU. The CPU receives the message information sent by each sensor, recombine the signals in the message information to generate new message information. In this way, since the CPU processes the code information corresponding to the message information when processing the message information, the code needs to be processed line by line, and the processing speed is slow. Therefore, when extracting and forwarding the message information, the efficiency is low, and the CPU has to process a large number of signal routes, which increases the CPU load rate.

[0044] In order to solve the above problems, the processor in the embodiment of the present application may be an application-specific integrated circuit ASIC chip, and the structure of the ASIC chip is as follows: Figure 2 The ASIC chip has parallel processing capabilities, so in the embodiment of the present application, the ASIC chip replaces the traditional central processing unit (CPU) to process multiple messages, thereby improving the message processing efficiency, reducing the transmission link delay of the signal routing, reducing the CPU load rate, and supplementing the saved computing power to other functions to achieve the effect of hardware acceleration.

[0045] In some embodiments of the present application, the number of ASIC chips can be at least one, and each application-specific integrated circuit ASIC chip is connected through a network, which greatly increases the number of internal and external devices mounted in the system. Compared with the communication architecture of the traditional vehicle-mounted electronic control system, in which there is only one CPU, in the embodiments of the present application, multiple ASIC chips can be connected to different sensors respectively, with simple lines, which simplifies the complexity of the vehicle body control network and increases the flexibility of the design of the vehicle-mounted electronic control system communication network.

[0046] In some embodiments of the present application, when the ASIC chip is set up, it can be connected to the sensors corresponding to the edge nodes of the vehicle respectively, for example, it can be connected to the sensors corresponding to the windows, wipers, lights, etc., so as to enhance the hardware acceleration of the edge nodes of the vehicle and effectively reduce the CPU load rate.

[0047] The signal processing method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0048] Figure 4 is a flow chart of a signal processing method provided in an embodiment of the present application, such as Figure 4 As shown, the signal processing method can be applied to the above Figure 1 The signal processing method may specifically include steps 410 to 430.

[0049] Step 410: Receive at least one message, and parse the first target message to obtain a signal value of a first target signal in the first target message and a first storage position of the first target signal in a storage table.

[0050] The first target message may be any one of the at least one message, and the first target signal may be any one of the multiple signals in the first target message.

[0051] In some embodiments of the present application, a message may contain multiple signals, and the first target signal may be any one signal in the first target message, or any multiple signals.

[0052] The first storage location may be a storage location of the first target signal in the storage table.

[0053] It should be noted that the signal storage module may include a storage table, and the position of each signal to be stored in the storage table can be preset. The signal extraction module may have a signal table, which stores the identity code of each message, the signal contained in each message, and the storage position of each signal in the storage table. Therefore, after receiving the message, the signal table can be queried according to the identity code of the message to determine which signals are contained in the message and the storage positions of these signals in the storage table.

[0054] In some embodiments of the present application, in order to accurately obtain the signal value of the first target signal and the first storage position of the first target signal in the storage, step 410 may specifically include:

[0055] Parsing the first target message to obtain a signal value of a first target signal in the first target message;

[0056] Using the identity identification code of the first target message as a keyword to search in the signal table, and obtaining at least one signal contained in the first target message;

[0057] According to the first target signal and the correspondence between the signals pre-stored in the signal table and their storage positions in the storage table, the first storage position of the first target signal in the storage table is obtained.

[0058] In some embodiments of the present application, the first target message is parsed to obtain which signals are in the first target message, and then the signal value of each signal is obtained. Then, the identity code of the first target message can be used to query the signal table, and the storage position of each signal in the first target message in the storage table can be queried from the signal table.

[0059] In an embodiment of the present application, the signal extraction module can obtain the signal value of the first target signal by parsing the first target message, and can use the identity identification code of the first target message to query in the signal table, and can query the first storage position of the first target signal in the storage table from the signal table, so that the signal value of the first target signal and the first storage position of the first target signal in the storage table can be accurately obtained.

[0060] Step 420: Store the signal value in a first storage location.

[0061] In some embodiments of the present application, after receiving the signal value of the first target signal, the signal storage module stores the signal value in the first storage location.

[0062] Step 430: When it is determined that the packetization operation on the first target signal is triggered, the signal value of the first target signal is obtained from the first storage location, and the first target signal is packetized based on the signal value to obtain a target message.

[0063] The target message is a message formed after packetizing the first target signal.

[0064] In an example, an ASIC receives two messages, message A and message B, wherein message A contains five signals, signal 1, signal 2, signal 3, signal 4, and signal 5, and message B contains six signals, signal 6, signal 7, signal 8, signal 9, signal 10, and signal 11. If signals 1, signal 2, and signal 3 in message A, and signals 8 and signal 9 in message B are to be repackaged at this time, the message formed after repackaging signals 1, signal 2, signal 3, and signals 8 and signal 9 is used as the target message.

[0065] In some embodiments of the present application, when it is determined that a packetization operation on the first target signal is triggered, the signal value of the first target signal may be acquired from the first storage location.

[0066] In some embodiments of the present application, determining the triggering of the packetization operation on the first target signal may be determined in different ways according to different types of the first target signal. Specifically, when the first target signal is an event trigger signal, the first target signal is transmitted to the signal packetization module to determine that the packetization operation on the first target signal is triggered. When the first target signal is a periodic trigger signal, when the time reaches the periodic trigger time of the first target signal, it is determined that the packetization operation on the first target signal is triggered.

[0067] In some embodiments of the present application, Figure 2 As shown, the signal storage module also includes a timer, a failure table and a failure management unit, and the failure table contains the failure time of the first target signal.

[0068] In order to effectively manage the first target signal, after step 420, the above method may further include:

[0069] When the time of the timer reaches the expiration time of the first target signal, generating an expiration start signal;

[0070] Based on the failure start signal, poll each signal in the signal table to obtain a first storage position of the first target signal in the storage table;

[0071] A first target signal at a first storage location is managed.

[0072] The failure initiation signal may be a signal generated by the failure management unit when the first target signal fails.

[0073] In some embodiments of the present application, when the timer reaches the expiration time of the first target signal, it means that the first target signal has failed. Then, a failure start signal can be generated based on the failure management unit, and the failure start signal can be sent to the signal extraction module. In response to the failure start signal, the signal extraction module can poll each signal in the signal table to obtain the first storage position of the first target signal in the storage table, and then manage the first target signal at the first storage position based on the signal storage module. Specifically, it can be based on Figure 2 The signal management unit in the signal management unit manages it, for example, the signal value of the first target signal at the first storage location may be deleted, so that when the first target signal is subsequently packaged, the signal value of the first target signal is not obtained, thereby avoiding errors in the re-packaged target message.

[0074] In an embodiment of the present application, when the timer reaches the expiration time of the first target signal, a failure start signal is generated, and based on the failure start signal, each signal in the signal table is polled to obtain the first storage position of the first target signal in the storage table, and the first target signal at the first storage position is managed. In this way, the signal that has expired can be managed to avoid errors in the subsequent re-packaged target message.

[0075] In some embodiments of the present application, Figure 2 As shown, the signal storage module may further include an initial value table, in which the initial value table includes the initial time when the processor is started, and correspondingly, the failure table may also include the failure value of the first target signal.

[0076] In order to further improve the accuracy of the packaged target message, after step 420, the above method may further include:

[0077] Outside the initial time, when the packetization operation on the first target signal is not triggered or the first target signal fails, the failure value of the first target signal is obtained from the failure table, and the first target signal is packetized based on the failure value to obtain the target message.

[0078] The initial time here may be the startup time of the processor.

[0079] In some embodiments of the present application, after the processor is started, that is, outside the initial time, if the package operation of the first target signal is not triggered, that is, the first target signal does not reach the signal package module, that is, the first target signal is not transmitted to the signal package module, or the first target signal fails, the failure value of the first target signal in the failure table can be fed back to the signal package module based on the signal storage module, so that the signal package module packages the first target signal based on the failure value of the first target signal.

[0080] In one example, sensor A has a signal value of a certain signal before 10 o'clock. After 10 o'clock, the bus responsible for transmitting the signal fails, and the ASIC chip cannot receive the signal value of the signal. The expiration time of the signal value can be set in advance. For example, the expiration time is 1 hour. If the signal value is needed for calculation or packaging between 10-11 o'clock, the signal value of the signal at the current time can be directly obtained for calculation. If the signal value is needed for calculation or packaging after 11 o'clock, the signal value of the signal collected before 10 o'clock can be obtained from the failure table (since the signal before 10 o'clock has failed, it is called a failure value) for calculation or packaging.

[0081] In an embodiment of the present application, outside the initial time of processor startup, the packetization operation on the first target signal is not triggered, or the first target signal fails, the failure value of the first target signal is obtained from the failure table, and the first target signal is packetized based on the failure value to obtain the target message. In this way, when the signal value fails, the failure value can continue to be used for packetization, thereby avoiding the situation where the signal value of a signal cannot be obtained in real time when the bus corresponding to a signal fails, thereby affecting the packetization.

[0082] In some embodiments of the present application, the initial value table may also include an initial value of the first target signal.

[0083] In order to further improve the accuracy of the packaged target message, after step 420, the above method may further include:

[0084] During the initial time, if the packetization operation on the first target signal is not triggered or the first target signal fails, the initial value of the first target signal is obtained from the initial value table, and the first target signal is packetized based on the initial value to obtain a target message.

[0085] The initial value table stores the initial value of each signal.

[0086] In some embodiments of the present application, within the initial time, that is, during the startup of the processor, if the package assembly operation of the first target signal is not triggered, that is, the first target signal does not reach the signal package assembly module, or the first target signal fails, the initial value of the first target signal can be fed back to the signal package assembly module based on the signal storage module, so that the signal package assembly module packages the first target signal based on the initial value of the first target signal.

[0087] In an embodiment of the present application, within the initial time, when the packaging operation on the first target signal is not triggered, or the first target signal fails, the initial value of the first target signal is obtained from the initial value table, and the first target signal is packaged based on the initial value to obtain the target message. In this way, at the initial stage of processor startup, the initial value of the first target signal can be used for packaging, thereby ensuring the smooth packaging of the first target signal.

[0088] In some embodiments of the present application, step 430 may specifically include:

[0089] When it is determined that a packetization operation is triggered on the first target signal and the first target signal is not invalid, a signal value of the first target signal is obtained from a first storage position in the storage table.

[0090] In some embodiments of the present application, if the first target signal reaches the signal packaging module, that is, triggering a packaging operation on the first target signal, and the first target signal is not invalid, that is, the first target signal is transmitted normally, then the signal value of the first target signal stored at the first storage position in the storage table can be fed back to the signal packaging module based on the signal storage module, and the signal packaging module can package the first target signal based on the signal value.

[0091] In an embodiment of the present application, when it is determined that a package grouping operation is triggered for the first target signal and the first target signal is not invalid, the signal value of the first target signal is obtained from the first storage position in the storage table. In this way, the real-time valid signal value of the first target signal can be used for package grouping, thereby ensuring the accuracy of package grouping.

[0092] In some embodiments of the present application, reference Figure 5 , Figure 5 The storage format of the signal in the storage table, initial value table and failure table is Figure 5 In the figure, the storage rules of signals are explained by taking signal A and signal B as examples. For example, the bit width of signal A is 50, and the bit width of signal B is 80. Taking into account the signal storage attribute information, signal A occupies 3 storage units and signal B occupies 4 storage units.

[0093] It should be noted that Figure 5 The data area format arrangement of the storage table, initial value table and failure table in the table remains consistent.

[0094] In some embodiments of the present application, Figure 2 As shown, the signal packaging module includes a message table, which includes the signals to be packaged and the storage location of the signals to be packaged in the storage table. The signals to be packaged may include the first target signal.

[0095] In an example, an ASIC receives two messages, message A and message B, wherein message A contains five signals, signal 1, signal 2, signal 3, signal 4, and signal 5, and message B contains six signals, signal 6, signal 7, signal 8, signal 9, signal 10, and signal 11. If signals 1, signal 2, and signal 3 in message A and signals 8 and signal 9 in message B are to be repackaged, then signals 1, signal 2, signal 3, and signals 8 and signal 9 are the signals to be packaged, and signals 1, signal 2, and signal 3 here can be the first target signals.

[0096] In order to accurately obtain the target message, the above step 430 may specifically include:

[0097] When it is determined that a packetization operation is triggered on the first target signal, the first storage position of the first target signal in the message table in the storage table is read, and an extraction instruction of the first target signal is generated based on the first storage position, and based on the extraction instruction, the signal value of the first target signal is obtained from the first storage position.

[0098] The message table includes a signal to be packaged that is to be packaged, and the signal to be packaged includes a first target signal.

[0099] In some embodiments of the present application, when it is determined that the first target signal is triggered to perform a packetization operation, the signal packetization module can read the first storage position of the first target signal in the message table in the storage table, and then generate an extraction instruction for the first target signal based on the first storage position, and send the extraction instruction to the signal storage module. According to the extraction instruction, the signal storage module can obtain the signal value of the first target signal from the first storage position and send it to the signal packetization module. The signal packetization module receives the signal value of the first target signal and packets the first target signal according to the signal value. In other words, regardless of whether the first target signal is an event trigger signal or a periodic trigger signal, the signal packetization module can determine which signals are included in the packetized message and which positions of these signals in the storage table by reading the message table, and then read the storage table to obtain the signals for packetization.

[0100] In an embodiment of the present application, when it is determined that a packetization operation is triggered on the first target signal, the first storage position of the first target signal in the message table in the storage table is read, and an extraction instruction for the first target signal is generated based on the first storage position. Based on the extraction instruction, the signal value of the first target signal is obtained from the first storage position, so that the signal to be packetized can be accurately determined, and the signal value of the signal to be packetized can be accurately determined, thereby obtaining an accurate target message.

[0101] In some embodiments of the present application, when the first target signal is an event trigger signal, the signal package module may further include a periodic table, which includes the sending time and number of sending of the first target signal, and a protection time, wherein the protection time is a preset minimum interval time between adjacent period trigger signals and event trigger signals. The protection time here can be set according to user needs and is not limited in the embodiments of the present application.

[0102] like Figure 6 As shown, Figure 6 Figure 1 is a schematic diagram of the relationship between the periodic trigger signal and the event trigger signal. The interval between a periodic trigger and an event trigger is the protection time.

[0103] In order to further improve the accuracy of the target message, when the first target signal is an event trigger signal, step 430 may specifically include:

[0104] When it is determined that a packetization operation is triggered on the first target signal, and the event trigger of the first target signal is valid, and the timer time reaches the sending time, and the protection time of the first target signal is 0, and the number of times the first target signal is sent is not 0, the signal value of the first target signal is obtained from the first storage location.

[0105] In some embodiments of the present application, when it is determined that the packetization operation on the first target signal is triggered, other conditions need to be met before the signal value of the first target signal can be obtained from the first storage location. Specifically, if the event trigger of the first target signal is valid, and the timer time reaches the sending time of the event trigger signal, and the protection time is 0, and the number of transmissions is not 0, the signal value of the first target signal can be obtained from the first storage location.

[0106] In some embodiments of the present application, the event trigger validity of the first target signal may specifically be whether the event trigger identification bit of the first target signal is valid. Each signal has its corresponding trigger identification bit, which can be pre-set. If the identification bit is "1", it proves that the triggering of the signal is valid. If the trigger identification bit is "0", it proves that the triggering of the signal is invalid. Therefore, when it is detected that the trigger identification bit of the event trigger of the first target signal is valid, it proves that the event triggering of the first target signal is valid.

[0107] In an embodiment of the present application, when it is determined that a packetization operation is triggered on the first target signal, and the event trigger of the first target signal is valid, and when the timer time reaches the sending time, and the protection time of the first target signal is 0, and the number of times the first target signal is sent is not 0, the signal value of the first target signal is obtained from the first storage location, so that the signal value of the first target signal can be accurately obtained.

[0108] In some embodiments of the present application, when the first target signal is a periodic trigger signal, the periodic table may also include the sending time of the next period of the first target signal, that is, the periodic table includes the time for sending the first target signal in the next period.

[0109] In order to further improve the accuracy of the target message, when the first target signal is a periodic trigger signal, step 430 may specifically include:

[0110] When it is determined that a trigger is provided to perform a packet operation on the first target signal, based on a periodic trigger signal, when the periodic trigger of the first target signal is valid, the sending time in the periodic table is traversed, and when it is determined that the sending time of the next period of the first target signal in the periodic table is the same as the timing trigger time and the protection time is 0, the signal value of the first target signal is obtained from the first storage location.

[0111] Among them, the periodic trigger signal is generated in response to the timing trigger time pre-set by the user in the timer, that is, if the user pre-sets the timing trigger time in the timer, a periodic trigger signal can be generated, and the periodic trigger signal can include the timing trigger time pre-set in the timer.

[0112] In some embodiments of the present application, when it is determined that the signal packaging module receives a periodic trigger signal, other conditions need to be met before the signal value of the first target signal can be obtained from the first storage location. Specifically, when the periodic trigger of the first target signal is valid, the sending time in the periodic table is traversed, and the sending time of the next period of the first target signal in the periodic table is determined to be the same as the timing trigger time, that is, when the timer time reaches the periodic sending time of the periodic trigger signal, and the protection time is 0, the signal value of the first target signal can be obtained from the first storage location.

[0113] In some embodiments of the present application, the validity of the periodic trigger of the first target signal may specifically be whether the periodic trigger identification bit of the first target signal is valid. Each signal has its corresponding trigger identification bit, which can be pre-set. If the identification bit is "1", it proves that the triggering of the signal is valid. If the identification bit is "0", it proves that the triggering of the signal is invalid. Therefore, when it is detected that the trigger identification bit of the periodic trigger of the periodic trigger signal is valid, it proves that the periodic triggering of the periodic trigger signal is valid.

[0114] In an embodiment of the present application, when it is determined that a trigger is provided to perform a packet operation on the first target signal, based on a periodic trigger signal, when the periodic trigger of the first target signal is valid, the sending time in the periodic table is traversed, and when it is determined that the sending time of the next period of the first target signal in the periodic table is the same as the timing trigger time, and the protection time is 0, the signal value of the first target signal is obtained from the first storage location, so that the signal value of the first target signal can be accurately obtained.

[0115] It should be noted that each signal has its corresponding trigger identifier, which can be obtained by the signal extraction module when parsing the message, and then transmitted to the signal packaging module along with the transmission of the signal. The signal packaging module can then determine whether the signal is an event trigger signal or a periodic trigger signal based on the trigger identifier.

[0116] In some embodiments of the present application, when the first target signal is a periodic trigger signal, after step 430, the method further includes:

[0117] The sending time of the next period of the first target signal in the periodic table and the protection time are updated.

[0118] In some embodiments of the present application, after obtaining the target message, the sending time of the next period of the first target signal in the periodic table and the protection time can be re-updated based on the signal packaging module, so as to facilitate the next packaging of the first target signal.

[0119] In some embodiments of the present application, when the first target signal is an event trigger signal, after step 430, the above method may further include:

[0120] The sending time and the sending number of the first target signal in the periodic table are reset.

[0121] In some embodiments of the present application, the signal packaging module may also reset the sending time and the number of sending times of the first target signal in the periodic table so as to package the first target signal according to the sending time and the number of sending times next time.

[0122] In some embodiments of the present application, the signal to be packaged may further include a second target signal. After the first target message is parsed, the above method may further include:

[0123] extracting attribute information of the first target signal and attribute information of the second target signal, and a signal value of the second target signal;

[0124] Step 430 may specifically include:

[0125] The first target signal and the second target signal are concatenated according to the attribute information of the first target signal and the attribute information of the second target signal, and the signal value of the first target signal and the signal value of the second target signal to obtain a target message.

[0126] Among them, for the first target signal or the second target signal, the attribute information may include the big and small ends, length, etc. of the target signal.

[0127] In some embodiments of the present application, when the first target signal and the second target signal are packaged, not only the signal value of the first target signal and the signal value of the second target signal are required, but also the attribute information of the first target signal and the attribute information of the second target signal are required, so that the first target signal and the second target signal can be packaged accurately to form an accurate target message. For example, for the first target signal, the first target signal has 5 bytes, each byte has 8 bits, and how these 8 bits are sorted needs to be known, so that the first target signal can be packaged completely when the package is subsequently packaged.

[0128] In an example, in an example, an ASIC receives two messages, message A and message B, wherein message A contains five signals, signal 1, signal 2, signal 3, signal 4, and signal 5, and message B contains six signals, signal 6, signal 7, signal 8, signal 9, signal 10, and signal 11. If signals 1, signal 2, and signal 3 in message A and signals 8 and signal 9 in message B are to be repackaged, then signals 1, signal 2, and signal 3, as well as signals 8 and signal 9 are the signals to be packaged, signals 1, signal 2, and signal 3 can be the first target signals, and signals 8 and signal 9 can be the second target signals. Then, attribute information of signals 1, signal 2, and signal 3, as well as attribute information of signals 8 and signal 9 can be obtained, and then based on the attribute information of each signal to be packaged, these signals to be packaged are packaged to obtain the target message.

[0129] In an embodiment of the present application, by extracting attribute information of the first target signal and the attribute information of the second target signal, as well as the signal value of the second target signal, and then splicing the first target signal and the second target signal according to the attribute information of the first target signal and the attribute information of the second target signal, as well as the signal value of the first target signal and the signal value of the second target signal, to obtain a target message, thereby obtaining an accurate target message composed of the first target signal and the second target signal.

[0148] In some embodiments of the present application, the first target signal is a periodic trigger signal, and the periodic table also has the sending time of the next cycle of the first target signal. The signal packaging module is specifically used to: when it is determined that the first target signal is triggered to perform a packaging operation, based on the periodic trigger signal, when the periodic trigger of the first target signal is valid, traverse the sending time in the periodic table, and when it is determined that the sending time of the next cycle of the first target signal in the periodic table is the same as the timing trigger time, and the protection time is 0, obtain the signal value of the first target signal from the first storage location; wherein, the periodic trigger signal is generated in response to the timing trigger time pre-set by the user in the timer, and the periodic trigger signal includes the timing trigger time pre-set in the timer.
