[0049] In order to make the technical solutions and advantages of the present application clearer, several embodiments of the present application will be described in further detail in conjunction with the accompanying drawings, but the following described embodiments are only several preferred embodiments of the present application and are not used to limit the present application.

[0050] Embodiment one, see Figure 1 The present embodiment is described. The function arbitration device of a digital acquisition module in the present embodiment comprises:

[0051] an acquisition module, a state machine and a data control module;

[0052] The acquisition module is used to acquire configuration signals, trigger signals and data signals and transmit the acquired signals to the state machine;

[0053] The state machine is used to analyze the received configuration signals and analyze and arbitrate the data according to the received trigger signals and data signals to obtain the data that has completed arbitration;

[0054] The data control module is used to interact with the state machine and is also used to control the storage of the data that has completed arbitration by the state machine.

[0055] Specifically, the device in the present embodiment realizes the acquisition and storage control of data, analyzes and arbitrates the configuration signals input by the user by the state machine in combination with the trigger signals and data signals, so as to control the storage of the data that has completed arbitration by the data control module.

[0056] Embodiment two, the present embodiment is a further limitation of the function arbitration device of a digital acquisition module in embodiment one, and the acquisition module comprises: a transient waveform acquisition unit, an envelope waveform acquisition unit and a double-capture waveform acquisition unit;

[0057] The transient waveform acquisition unit is used to directly store the waveform data acquired in real time;

[0058] The envelope waveform acquisition unit is used to acquire the maximum value and the minimum value in the waveform data every fixed time and store the waveform composed of the maximum value and the minimum value;

[0059] The double-capture waveform acquisition unit is used to store the transient waveform data in the normal mode, and when the trigger signal is acquired in the process of storing the transient waveform data, it is converted into the envelope waveform acquisition unit for storage.

[0060] Embodiment three, the embodiment is further limited to the function arbitration device of the digital acquisition module of embodiment one, the acquisition unit further includes: start storage opportunity module, stop storage opportunity module and start & stop storage opportunity module;

[0061] The start storage opportunity module is configured to start storage from the first trigger signal and stop storage until a preset number of points is reached or a stop command is received.

[0062] The stop storage opportunity module is configured to execute a start command and stop storage until a first trigger signal is received or a preset number of points is reached.

[0063] The start & stop storage opportunity module is configured to execute a start command or receive a first trigger signal to start storage, and stop storage until a second trigger signal is received, a stop command is received or a preset number of points is reached.

[0064] Specifically, the embodiment is described in combination with embodiment two. The start storage opportunity module, the stop storage opportunity module and the start & stop storage opportunity module further include pre-trigger, post-trigger and trigger priority functions. The pre-trigger refers to setting a percentage of data to be stored in advance before a trigger starts in a start mode (i.e., the start storage opportunity module is running), a start & stop mode (i.e., the start & stop storage opportunity module is running) or a double capture mode. When the trigger starts, the remaining percentage of data is stored. The post-trigger refers to setting a percentage of data to be stored after a stop condition is met in a stop mode (i.e., the stop storage opportunity module is running) or a start & stop mode (i.e., the start & stop storage opportunity module is running). The trigger priority is to wait for the pre-trigger to arrive. If the percentage of data set by the pre-trigger has not been stored, the operation is selected as follows: when the trigger priority is turned on, the trigger is accepted even if the percentage of data set by the pre-trigger has not been stored, and the subsequent normal sampling mode is entered. When the trigger priority is turned off, only the trigger after the percentage of data set by the pre-trigger is stored is accepted.

[0065] The acquisition unit further includes a single / repeated trigger setting module. When the single trigger setting module is in a mode value, the above-mentioned three storage opportunity modules are triggered once and storage is stopped. When the repeated trigger setting module is in a mode value, the above-mentioned three storage opportunity modules are triggered for a set number of times.

[0066] The acquisition unit further comprises a memory segmentation module, which is configured to set a memory segmentation block number and a start-stop point, and to store the signal multiple times within the memory segmentation block number available for user selection.

[0067] Embodiment four, the embodiment is a further limitation of the function arbitration device of the digital acquisition module of embodiment one, the state machine is used for analyzing the configuration signal, comprising:

[0068] judging the signal type of acquisition;

[0069] processing the sampling information according to the signal type.

[0070] Specifically, the state analysis of the sampling signal needs to be performed:

[0071] The sampling enable Sa_en means that the sampling module starts to work and triggers, but no data is stored in the DDR. The sampling enable is a command signal issued by the system and does not need to be analyzed.

[0072] The sampling start Bank_start (samp_en) means that the sampling point is stored in the DDR, and subsequent uploading and other operations are performed.

[0073] The sampling stop Bank_stop (samp_end) means that the storage of the sampling point in the DDR is stopped.

[0074] Embodiment five, see Figure 2 This embodiment is a further limitation of the function arbitration device of the digital acquisition module of embodiment three, the data analysis and arbitration according to the acquisition trigger signal and the data signal, specifically:

[0075] judging the storage timing module of the trigger signal;

[0076] The Start storage timing module outputs the Trigger signal, the state machine receives the Trigger trigger signal and outputs data, and the output of data ends when the preset recording length is reached;

[0077] The stop storage timing module outputs the START signal, the state machine receives the START trigger signal and outputs data, and the output of data ends when the second trigger signal is acquired or the preset recording length is reached;

[0078] The start & stop storage timing module outputs the signal, the state machine receives the START trigger signal and outputs data, and the output of data ends when the STOP trigger signal is received or the preset recording length is reached.

[0079] Embodiment six, see Figure 3 The present embodiment is a further limitation of the function arbitration device of the digital acquisition module of embodiment one, the data control module comprises: a Trend / Realtime Wave Points Counter, a Trigger Points Counter, a Double Sampling Realtime Wave Points Counter, a Post Trigger Points Counter and a Pre Trigger Points Counter;

[0080] The Trend / Realtime Wave Points Counter is used to record the sampling points of the trend waveform data or the realtime waveform data in normal mode.

[0081] The Trigger Points Counter is used to determine whether the number of triggers reaches the number of memory division settings in double sampling mode, if the number of triggers reaches the number of memory division settings, the previous stored number of times is invalidated when the new trigger is received.

[0082] The Double Sampling Realtime Wave Points Counter is used to record the sampling points of the realtime waveform after the trigger in double sampling mode.

[0083] The Post Trigger Points Counter is used to pull high the output when the number of outputs satisfies the number of post trigger settings within the time after receiving Post_trigger_stop in post trigger mode.

[0084] The Pre Trigger Points Counter is used to pull high the output when the number of outputs satisfies the number of pre trigger settings within the time after the signal enable Sa_en in pre trigger mode.

[0085] Specifically, the Trend / Realtime Wave Points Counter is used to record the sampling points of the trend waveform or the realtime waveform in normal mode: after starting sampling, the number of inputs of the trend waveform is counted, when the number of data inputs reaches SampNumMax[30:0] or the STOP signal enters, the counting is stopped and the output is pulled high. When the sampling rate is set to double sampling mode, the counter is responsible for the sampling points of the double sampling trend waveform.

[0086] The Trigger Num Counter is used to determine whether the number of triggers reaches the number of memory partitions. If the number of triggers reaches the number of memory partitions, the new trigger is invalid. When the number of triggers is greater than the number of memory partitions, the trigger is invalid. When the number of triggers does not reach the number of memory partitions, if the trend waveform storage is full (the trend waveform storage counter is full), the number of triggers is cleared. When a sampling is restarted, the trigger counter is cleared.

[0087] The Realtime Wave Points Num Counter is used to record the number of instantaneous waveforms after a trigger in the double sampling mode. When a trigger is triggered and valid (whether the trigger is valid is determined according to the Trigger Num Counter), the counting starts. The maximum value of the counting needs to be calculated according to the number of channels and the number of memory partitions. If a new trigger is received during the output of the instantaneous waveform, the counter of the module is reset. When the double-channel sampling is started, the maximum number of memory partitions of a single channel is 512. 1 GB / 2 / 512 = 1 MB of memory for each partition = 2M pts. When the single-channel sampling is started, the maximum number of memory partitions of a channel is 1024. 1 GB / 1024 = 1 MB of memory for each partition = 2M pts. When the counter reaches the maximum value, the output is pulled high.

[0088] The Post Trigger Points Counter is used to pull the output high when the number of points output within the time after receiving the Post_trigger_stop reaches the number of points set by the post trigger.

[0089] The Pre Trigger Points Counter is used to pull the output high when the number of points output within the time after the signal enable Sa_en reaches the number of points set by the pre trigger.

[0090] Embodiment seven, a method for designing a function arbitration logic of a digital acquisition module, the method is realized based on the arbitration device in any one of embodiments one to six, and the method comprises the following steps:

[0091] acquiring a configuration signal, a trigger signal and a data signal, and transmitting the acquired signals to a state machine;

[0092] The received configuration signal is parsed, and data analysis and arbitration are performed according to the received trigger signal and data signal, the data after arbitration is obtained, and data storage is performed.

[0093] The data control module interacts with the state machine data, and is further configured to control the state machine to store the data after arbitration.

[0094] Embodiment eight, the embodiment is a further limitation of the function arbitration logic design method of the digital acquisition module of embodiment seven, and the parsing configuration signal comprises:

[0095] Judging the mode of the configuration signal;

[0096] According to the signal mode, the preset sampling data point reaches the record length signal.

[0097] Embodiment nine, the computer device comprises a memory and a processor, the memory stores a computer program, and when the processor runs the computer program stored in the memory, the processor executes the function arbitration logic design method of the digital acquisition module according to embodiment seven.

[0098] Embodiment ten, the computer readable storage medium stores a computer program, and the computer program executes the function arbitration logic design method of the digital acquisition module according to embodiment seven.

[0099] Embodiment eleven, see Figure 2 This embodiment is a specific description of the function arbitration device and logic design method of the digital acquisition module provided by the application, which is specific to:

[0100] The function arbitration device comprises:

[0101] The acquisition module, the state machine and the data control module;

[0102] The acquisition module is configured to acquire configuration signals, trigger signals and data signals, and transmit the acquired signals to the state machine;

[0103] The state machine is configured to parse the configuration signal, and perform data analysis and arbitration according to the received trigger signal and data signal, and obtain the data after arbitration;

[0104] The data control module is configured to interact with the state machine data, and is further configured to control the state machine to store the data after arbitration.

[0105] Specifically, the state machine can receive user configuration conditions and modes, and take the number of data points and triggers as input signals to control the time of storing data.

[0106] As shown in the following Figure 2 The state transition diagram of the state machine of the arbitration device is shown in the figure, and the MEALY type state machine is used. The state machine includes a STOP key and a START key. The STOP key is used to terminate storage, and the START key is used to start storage. The conditions and outputs at the time of state transition are marked in the figure. The change of the input signal directly affects the value of the output.

[0107] In the figure, the state analysis of the input signal includes:

[0108] Start_Stop_time_mode[1:0]: 00 start mode; 01 stop mode; 11 start & stop mode;

[0109] Single_repet_mode: 0 single mode; 1 repeat mode;

[0110] Trigger: input trigger signal;

[0111] START_TRIGGER, STOP_TRIGGER: signals of the keys issued from the upper computer;

[0112] Sa_en: sampling enable signal issued from the system;

[0113] Samp_num_reach_max: signal that the sampling data points from the coarse trigger module reach the set recording length.

[0114] It also includes the state analysis of sampling:

[0115] The sampling enable Sa_en means that the sampling module starts to work and will also generate a trigger, but there is no data stored in the DDR. The sampling enable is a command signal issued from the system and does not need to be analyzed.

[0116] The sampling start Bank_start (samp_en) means that the sampling points are stored in the DDR, and subsequent uploading and other operations.

[0117] The sampling stop Bank_stop (samp_end) means to stop storing sampling points in the DDR.

[0118] It also includes the judgment of the start and stop of sampling, that is, the analysis and arbitration of data according to the collected trigger signal and data signal

[0119] 1. The trigger timing sequence Start_Stop_time_mode[1:0] is determined: 00 start mode; 01 stop mode; 11 start & stop mode.

[0120] 2. If it is start mode, the data is outputted when the trigger signal is received, and the output is stopped when the set record length is reached (the record length is the length of one sample set); if it is stop mode, the data is outputted when the START trigger signal is received, and the output is stopped when the trigger time or the set record length is reached; if it is start & stop mode, the data is outputted when the START trigger signal is received, and the output is stopped when the STOP trigger signal is received or the set record length is reached.

[0121] The data control module is used to control the storage of the data that has completed arbitration by the state machine and the collection of the data by the auxiliary control state machine.

[0122] As shown in Figure 3 The data control module is composed of five different counters. The five counters are respectively a trend / realtime wave points counter, a trigger num counter, a double sampling trend wave points counter, a post-trigger points counter and a pre-trigger points counter. The input signals of the data control module include the control start and end signals transmitted by the main state machine, and meanwhile, the results generated by the counters affect the judgment conditions of the state machine jump in return.

[0123] The trend / realtime wave points counter is used to record the sampling points of the trend wave or the realtime wave in the normal mode: after the sampling is started, the number of the trend wave inputs is counted, and when the number of the data inputs reaches SampNumMax[30:0] or the STOP signal is entered, the counting is stopped and the output is pulled high. When the sampling rate is set as the double sampling mode, the counter is responsible for the sampling points of the double sampling trend wave.

[0124] The trigger num counter is used to determine whether the number of the trigger reaches the number of memory division setting in the double sampling, and if it reaches the number of memory division setting, the new trigger is invalid: when the number of the trigger in one sampling is greater than the number of memory division, the trigger at this time is invalid; when the number of the trigger does not reach the number of memory division, if the trend wave storage is full (the trend wave storage amount counter shows full), the number of the trigger is cleared; when the one sampling is restarted, the trigger counter is cleared.

[0125] Realtime Wave Points Num Counter The function of the double-sampling instantaneous waveform point number counter is to record the number of instantaneous waveform sampling points after triggering in double-sampling when the sampling mode is set to double-sampling. When there is a trigger in double-sampling and it is valid (whether the trigger is valid is determined according to Trigger Num Counter), the counting starts, and the maximum value of the counting needs to be calculated according to the number of channel openings and the number of memory partitions. If there is a new trigger during the output of the instantaneous waveform, the counter of this module is reset. When the double-channel sampling is started, the maximum number of single-channel memory partitions is 512: 1 GB / 2 / 512 = 1 MB of memory for each partition = 2M pts. When the single-channel sampling is started, the maximum number of channel memory partitions is 1024: 1 GB / 1024 = 1 MB of memory for each partition = 2M pts. When the counter reaches the maximum value, the output is pulled high.

[0126] Post Trigger Points Counter The function of the post-trigger point number counter is to pull high the output when the number of points output within the time after receiving the Post_trigger_stop meets the number of points set by the post-trigger.

[0127] Pre Trigger Points Counter The function of the pre-trigger point number counter is to pull high the output when the number of points output within the time after the signal enable Sa_en meets the number of points set by the pre-trigger.
