Description

Technical Field

[0001] This invention relates to the field of signal compensation, and in particular to a signal compensation method, apparatus, storage medium, and electronic device. Background Technology

[0002] A rail scale is a weighing instrument used to measure the load of vehicles, specifically bulk cargo in freight cars. It typically includes several sensors to detect the vehicle's load information. These sensors collect the pressure values ​​as the vehicle passes over the scale, converting these pressure values ​​into analog voltage signals. An analog-to-digital converter (ADC) connected to the sensors then converts these analog voltage signals into digital voltage signals, which are transmitted to a processor connected to the ADC. The processor processes the received digital voltage signals to obtain the weighing value of the vehicle after passing through the rail scale.

[0003] However, in actual use, due to network signal problems, when the signal collector sends the collected digital signal to the corresponding weight calculation processor, data packets may be lost, resulting in incomplete data obtained by the processor, and thus the corresponding load cannot be accurately calculated. Summary of the Invention

[0004] To address the aforementioned technical problem of inaccurate load calculation due to incomplete data acquired by the processor, the present invention adopts the following technical solution:

[0005] According to one aspect of the present invention, a signal compensation method is provided, applied to a signal acquisition device. The signal acquisition device includes at least one symmetrical signal acquisition group, at least one first storage space, and at least one second storage space. Each symmetrical signal acquisition group includes two signal acquisition units, and the signal difference acquired by the two signal acquisition units at the same time belongs to a first preset interval. Each symmetrical signal acquisition group corresponds to a first storage space and a second storage space.

[0006] Signal compensation methods include the following steps:

[0007] The initial signals acquired by the two signal acquisition units included in the symmetrical signal acquisition group are cyclically and alternately stored in the first storage space and the second storage space.

[0008] The two sets of initial signals corresponding to the two signal acquisition units in the full storage space are compared and processed to generate a signal difference sequence.

[0009] Send all initial signals in the full storage space to the target terminal, and clear the initial signals stored in the full storage space.

[0010] Based on the obtained waveform missing information and the corresponding signal difference sequence, signal compensation information is generated.

[0011] Furthermore, the initial signals acquired by the two signal acquisition units included in the symmetrical signal acquisition group are cyclically and alternately stored in the first storage space and the second storage space, including:

[0012] The initial signal is stored in either the first or second storage space.

[0013] If any storage space is full, the subsequent initial signals will be stored in another storage space that is not full.

[0014] Furthermore, the initial signal includes the unit identifier, the sequence identifier, and the signal value.

[0015] The two sets of initial signals corresponding to the two signal acquisition units in the fully loaded storage space are compared and processed to generate a signal difference sequence, including:

[0016] Based on the unit identifiers corresponding to the two initial signals, generate the group identifiers corresponding to the signal difference sequence.

[0017] If the absolute value of the difference between the two signal values ​​corresponding to the same sequence identifier in the two initial signals is less than or equal to the first threshold, then the first difference identifier corresponding to the sequence identifier is generated.

[0018] If the absolute value of the difference between the two signal values ​​corresponding to the same sequence identifier in the two initial signals is greater than the first threshold, then a second difference identifier corresponding to the sequence identifier is generated.

[0019] Furthermore, the initial signal includes the unit identifier, the sequence identifier, and the signal value.

[0020] The two sets of initial signals corresponding to the two signal acquisition units in the fully loaded storage space are compared and processed to generate a signal difference sequence, including:

[0021] Based on the unit identifiers corresponding to the two initial signals, generate the group identifiers corresponding to the signal difference sequence.

[0022] If the absolute value of the difference between two signal values ​​corresponding to the same sequence identifier in two sets of initial signals is less than or equal to the first threshold, then the signal difference identifier corresponding to the sequence identifier is the difference between the two signal values.

[0023] If the absolute value of the difference between two signal values ​​corresponding to the same sequence identifier in two sets of initial signals is greater than the first threshold, then the signal difference identifier corresponding to the sequence identifier is an empty set.

[0024] Furthermore, the waveform missing information includes the unit identifier and the missing sequence information.

[0025] Based on the obtained waveform missing information and the corresponding signal difference sequence, signal compensation information is generated, including:

[0026] Based on the unit identifier and group identifier, the corresponding signal difference sequence is determined as the target signal difference sequence.

[0027] Based on the missing sequence information, the corresponding target signal difference identifier in the target signal difference sequence is determined.

[0028] Signal compensation information is generated based on the target signal difference identifier.

[0029] Furthermore, based on the target signal difference identifier, signal compensation information is generated, including:

[0030] If the target signal difference identifier is the first difference identifier, then the first signal compensation information is generated. The first signal compensation information is used to replace the target missing signal with the signal value at the corresponding position in another set of initial signals in the symmetrical signal acquisition group.

[0031] If the target signal difference identifier is the second difference identifier, then second signal compensation information is generated. The second signal compensation information is used to indicate that the target missing information cannot be compensated.

[0032] Furthermore, based on the target signal difference identifier, signal compensation information is generated, including:

[0033] If the target signal difference identifier is an empty set, then first signal compensation information is generated. The first signal compensation information is used to replace the target missing signal with the signal value at the corresponding position in another set of initial signals in the symmetrical signal acquisition group.

[0034] Furthermore, based on the target signal difference identifier, signal compensation information is generated, including:

[0035] If the target signal difference is identified as the difference between two signal values, then third signal compensation information is generated. The third signal compensation information is used to generate the target missing signal based on the signal value at the corresponding position in another set of initial signals in the symmetrical signal acquisition group.

[0036] According to a second aspect of the present invention, a signal compensation device is provided, applied to a signal acquisition device. The signal acquisition device includes at least one symmetrical signal acquisition group, at least one first storage space, and at least one second storage space. Each symmetrical signal acquisition group includes two signal acquisition units, and the signal difference acquired by the two signal acquisition units at the same time belongs to a first preset interval. Each symmetrical signal acquisition group corresponds to one first storage space and one second storage space.

[0037] The signal compensation device includes:

[0038] The circular storage module is used to cyclically and alternately store the initial signals acquired by the two signal acquisition units included in the symmetrical signal acquisition group into the first storage space and the second storage space.

[0039] The comparison processing module is used to compare the two sets of initial signals corresponding to the two signal acquisition units in the full storage space and generate a signal difference sequence.

[0040] The signal transmission module is used to send all the initial signals in the full-load storage space to the target terminal and clear the initial signals stored in the full-load storage space.

[0041] The compensation module is used to generate signal compensation information based on the acquired waveform missing information and the corresponding signal difference sequence.

[0042] According to a third aspect of the present invention, a non-transitory computer-readable storage medium is provided, which stores a computer program that, when executed by a processor, implements the signal compensation method described above.

[0043] According to a fourth aspect of the present invention, an electronic device is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the signal compensation method described above.

[0044] The present invention has at least the following beneficial effects:

[0045] In this invention, each symmetrical signal acquisition group corresponds to a first storage space and a second storage space. The initial signals acquired can be cyclically and alternately stored in these two storage spaces. When one storage space is full, the subsequently acquired initial signals continue to be stored in the other, less full storage space. Simultaneously, the two sets of initial signals corresponding to the two signal acquisition units in the full storage space are compared to generate a signal difference sequence. Since, in actual use, the two sensors symmetrically set on the track scale (i.e., the symmetrical signal acquisition group in this invention includes two signal acquisition units) typically have essentially the same acquisition conditions, the acquired signals are also essentially the same.

[0046] In this invention, by generating a signal difference sequence, it is possible to perform operations such as replacing and compensating for the missing signal in another signal acquisition unit in a symmetrical signal acquisition group when one signal acquisition unit acquires a normal signal, thereby compensating for the missing signal and further improving the accuracy of the final calculated load data.

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] As one possible embodiment of the present invention, such as Figure 1 As shown, a signal compensation method is provided, applied to a signal acquisition device 2. The signal acquisition device 2 includes at least one symmetrical signal acquisition group, at least one first storage space, and at least one second storage space. Each symmetrical signal acquisition group includes two signal acquisition units, and the signal difference acquired by the two signal acquisition units at the same time belongs to a first preset interval. Each symmetrical signal acquisition group corresponds to a first storage space and a second storage space.

[0055] In practical use, a track scale 1 typically includes multiple sensors 10, which are fixedly installed on two railway tracks to collect corresponding signals, such as gravity signals and shear stress signals. Some sensors 10 are symmetrically positioned at the same location on both tracks (i.e., the symmetrical signal acquisition group in this invention includes two signal acquisition units), and the acquisition conditions of the two symmetrically positioned sensors 10 are generally similar, resulting in essentially identical signals. Based on these characteristics, this embodiment discloses the following compensation method for compensating for missing signals.

[0056] The signal compensation method includes the following steps:

[0057] S100: The initial signals acquired by the two signal acquisition units included in the symmetrical signal acquisition group are cyclically and alternately stored in the first storage space and the second storage space.

[0058] Specifically, multiple registers can be configured in data acquisition unit 2 so that each symmetrical signal acquisition group can correspond to two registers. The storage space of one register is the first storage space, and the storage space of the other register is the second storage space. Alternatively, a register with a larger storage space can be configured in data acquisition unit 2, and its storage space can be partitioned so that each symmetrical signal acquisition group can be allocated to two storage spaces.

[0059] Specifically, S100 includes:

[0060] S101: Store the initial signal in the first storage space or the second storage space. Specifically, the initial signal includes a cell identifier, a sequence identifier, and a signal value.

[0061] like Figure 2 As shown, during the measurement process, the data acquisition unit 2 can acquire the analog signals collected by the corresponding sensor 10 at a preset acquisition frequency (e.g., 5ms / time), and then send the signals to the corresponding analog-to-digital conversion module to convert them into digital signals. Since the data acquisition is continuous as the vehicle passes over the track scale 1, each sensor 10 acquires multiple initial signals, which can then form a signal sequence.

[0062] To clearly identify the identity of each signal, each signal value is assigned a corresponding unit identifier and sequence identifier. The unit identifier indicates which sensor 10 corresponds to the acquired signal. For example, if a data acquisition unit 2 contains 16 acquisition sensors 10, then 16 signal sequences can be generated during a single acquisition process. Each signal sequence corresponds to a unique unit identifier. This unit identifier indicates the correspondence between the signal sequence and the sensor 10. It can be represented in hexadecimal.

[0063] Each signal value in each signal sequence corresponds to a sequence identifier. This sequence identifier indicates the order in which each signal value appears in a signal sequence. It can be represented by a time interval from the start of the acquisition, such as 005, 010, 015, 020, etc.

[0064] S102: If any storage space is full, the subsequent initial signals will be stored in another storage space that is not full.

[0065] In this embodiment, "full storage space" means that the memory partition in the register used to store the initial signal is filled.

[0066] During storage, if either storage space (the first or the second storage space) becomes full, subsequently acquired signals are stored in the other, unloaded storage space. Simultaneously, after a storage space becomes full, a comparison process is performed, and after completion, all previously stored initial signals are cleared, making the space empty again. This allows for reuse once the other storage space becomes full. This achieves cyclical use of the two storage spaces.

[0067] Since the comparison processing utilizes the time gap created by storing the initial acquired signal into the partially filled storage space, it performs operations on the fully filled storage space. Therefore, in order to avoid delaying the smooth storage of the initial acquired signal, the processing time of the comparison processing needs to be less than or equal to the time it takes for the initial acquired signal to fill the partially filled storage space.

[0068] Specifically, the processing time can be controlled by adjusting the size of the first and second storage spaces or by adjusting the comparison processing algorithm, so that the processing time of the comparison processing is less than or equal to the time when the initial acquired signal is stored in the unfilled storage space.

[0069] S200: Compares the two sets of initial signals corresponding to the two signal acquisition units in the full-load storage space to generate a signal difference sequence.

[0070] Specifically, in this embodiment, the comparison process involves subtracting the signal values ​​at the same positions in two corresponding signal sequences and generating a corresponding signal difference identifier based on the difference. Since the signal is more stable and less prone to loss during the initial signal acquisition process from sensor 10 by the collector 2, the resulting signal sequence is a more comprehensive and accurate acquisition sequence. However, when the collector 2 packages the initial signal from the signal sequence into data and sends it to the corresponding processor 3 via the network, the network signal is unstable due to the environment where the collector 2 is located, often on railway tracks, making data loss highly likely. In this embodiment, by performing the comparison process, the approximate difference between the signals acquired by the two symmetrical sensors 10 can be recorded in advance when the signal sequence is more complete, facilitating later compensation.

[0071] Specifically, S200 may include:

[0072] S210: Generate the group identifier corresponding to the signal difference sequence based on the unit identifiers corresponding to the two initial signals.

[0073] S211: If the absolute value of the difference between two signal values ​​corresponding to the same sequence identifier in two sets of initial signals is less than or equal to the first threshold, then generate the first difference identifier corresponding to the sequence identifier. The first difference identifier is set to 1.

[0074] S212: If the absolute value of the difference between the two signal values ​​corresponding to the same sequence identifier in the two sets of initial signals is greater than the first threshold, then a second difference identifier corresponding to the sequence identifier is generated. The second difference identifier is set to 0.

[0075] In this embodiment, the first threshold can be calculated by statistically analyzing the difference between two sets of signals acquired simultaneously by two signal acquisition units in a symmetrical signal acquisition group during actual use. For example, the maximum, mode, median, or mean of the actual difference can be used.

[0076] After the above processing, a signal difference sequence with the same length as the signal sequence can be generated. This signal difference sequence will have a corresponding group identifier, which can be composed of the unit identifiers corresponding to two signal acquisition units in the symmetrical signal acquisition group, such as 01-02. Additionally, each signal difference identifier will also correspond to the sequence position identifier of the original initial acquired signal; the signal difference identifier can be 0 or 1. At this point, storing only this signal difference sequence in the register is sufficient to compensate for the lost signal, without needing to store all the original acquired data, thus saving storage space.

[0077] Furthermore, to further save storage space, only the second difference identifier can be stored in the signal difference sequence, while the signal difference identifier corresponding to the first difference identifier is 0. Since the two symmetrically arranged sensors 10 generally operate under essentially the same conditions, the signals they acquire are also essentially the same. Therefore, under normal circumstances, the occurrence of the first difference identifier "1" is far more frequent than the occurrence of the second difference identifier "0". Based on this characteristic, storing only 0s in the signal difference sequence can significantly save storage space.

[0078] The S200 may also include:

[0079] S220: Generate the group identifier corresponding to the signal difference sequence based on the unit identifiers corresponding to the two initial signals.

[0080] S221: If the absolute value of the difference between the two signal values ​​corresponding to the same sequence identifier in the two initial signals is less than or equal to the first threshold, then the signal difference identifier corresponding to the sequence identifier is the difference between the two signal values.

[0081] S222: If the absolute value of the difference between the two signal values ​​corresponding to the same sequence identifier in the two initial signals is greater than the first threshold, then the signal difference identifier corresponding to the sequence identifier is an empty set.

[0082] In the signal difference identifier generation method of this embodiment, the difference between two signal values ​​is directly recorded. Therefore, in subsequent data recovery, the missing signal value can be recovered more accurately based on the specific difference and the signal value at another corresponding position.

[0083] S300: Send all initial signals in the full storage space to the target terminal and clear the initial signals stored in the full storage space.

[0084] The target terminal in this step can be processor 3, which calculates the corresponding load information based on the signal sequence.

[0085] S400: Generate signal compensation information based on the obtained waveform missing information and the corresponding signal difference sequence.

[0086] Specifically, the missing waveform information includes the unit identifier and the missing sequence information.

[0087] The S400 includes:

[0088] S401: Based on the unit identifier and group identifier, determine the corresponding signal difference sequence as the target signal difference sequence.

[0089] If the unit identifier is a subset of the group identifier, then the signal difference sequence corresponding to the group identifier is determined as the target signal difference sequence.

[0090] S402: Based on the missing sequence information, determine the target signal difference identifier in the target signal difference sequence.

[0091] Missing sequence information is the original sequence identifier corresponding to the missing signal value, and the target signal difference identifier is the original sequence identifier in the target signal difference sequence.

[0092] S403: Generate signal compensation information based on the target signal difference identifier.

[0093] If S200 includes S210 to S211, then S403 includes:

[0094] S413: If the target signal difference identifier is the first difference identifier, then generate the first signal compensation information. The first signal compensation information is used to replace the target missing signal with the signal value at the corresponding position in another set of initial signals in the symmetrical signal acquisition group.

[0095] S423: If the target signal difference identifier is the second difference identifier, then generate second signal compensation information. The second signal compensation information is used to indicate that the target missing information cannot be compensated.

[0096] Because the processing in S210 to S211 only records the magnitude of the difference between two corresponding signal values ​​using 0 and 1, without recording the specific difference value, the resulting compensation information can only indicate whether the missing signal value can be directly replaced by a valid signal value. Furthermore, the replaced signal value may also differ from the original signal value. Therefore, although this embodiment can compensate for missing signal values, its accuracy is low.

[0097] If S200 includes S220 to S222, then S403 includes:

[0098] S433: If the target signal difference identifier is an empty set, then generate first signal compensation information. The first signal compensation information is used to replace the missing target signal with the signal value at the corresponding position in another set of initial signals in the symmetrical signal acquisition group.

[0099] S443: If the target signal difference is identified as the difference between two signal values, then a third signal compensation information is generated. The third signal compensation information is used to generate the target missing signal based on the signal value at the corresponding position in another set of initial signals in the symmetrical signal acquisition group.

[0100] Since the difference between two corresponding signal values ​​is recorded during the processing in S220 to S222, the accurate missing signal value can be recovered using the non-missing signal value and the corresponding difference. Therefore, this embodiment can not only compensate for missing signal values, but also achieve higher accuracy.

[0101] As another embodiment of the present invention, it also includes:

[0102] S500: Based on the number ξ of the second difference identifier or empty set in the signal difference sequence, generate the reliability δ of the signal compensation information. δ satisfies the following condition:

[0103]

[0104] Where K is the adjustment coefficient, such as K = 1.

[0105] Normally, under normal circumstances, the signal values ​​acquired by two signal acquisition units within the same symmetrical signal acquisition group at the same time are generally similar. However, during long-term use, sensor 10 may become damaged or malfunction, in which case the signal values ​​acquired by the two signal acquisition units at the same time may differ significantly. In existing processors 3, the corresponding load value can usually be calculated based on the input value without missing values. However, the more deviations in the input data, the greater the error in the calculated load value. In this embodiment, the confidence level δ is inversely proportional to ξ, and its variation pattern better matches the confidence level variation pattern in this scenario, thus enabling a more accurate generation of the corresponding confidence level value.

[0106] As another possible embodiment of the present invention, such as Figure 3 As shown, a signal compensation device is also provided, applied to a signal acquisition device. The signal acquisition device includes at least one symmetrical signal acquisition group, at least one first storage space, and at least one second storage space. Each symmetrical signal acquisition group includes two signal acquisition units, and the signal difference acquired by the two signal acquisition units at the same time belongs to a first preset interval. Each symmetrical signal acquisition group corresponds to one first storage space and one second storage space.

[0107] The signal compensation device includes:

[0108] The circular storage module is used to cyclically and alternately store the initial signals acquired by the two signal acquisition units included in the symmetrical signal acquisition group into the first storage space and the second storage space.

[0109] The comparison processing module is used to compare the two sets of initial signals corresponding to the two signal acquisition units in the full storage space and generate a signal difference sequence.

[0110] The signal transmission module is used to send all the initial signals in the full-load storage space to the target terminal and clear the initial signals stored in the full-load storage space.

[0111] The compensation module is used to generate signal compensation information based on the acquired waveform missing information and the corresponding signal difference sequence.
