Description

Technical Field

[0001] The present application relates to the field of measurement technology, and in particular to a synchronization system and method, a measurement system and method, a triggering device, and a storage medium. Background Art

[0002] Faced with complex test conditions with many test points, if the signals at each test point need to be monitored simultaneously, then the real-time requirements will be relatively high. In addition, due to the limited number of channels of a single measurement device, there will be applications that require the use of multiple measurement devices to synchronize measurements at different test points at the same trigger moment.

[0003] To meet the above test requirements, multiple measurement devices need to be externally triggered synchronously. In this case, a multi-channel trigger device is needed to convert the trigger signal of a single channel input into a trigger signal of a multi-channel output, which can be used to trigger the synchronous sampling of multiple measurement devices at the back end.

[0004] However, when test conditions become more complex, a single trigger device cannot meet the measurement requirements, and multiple trigger devices need to be cascaded. For users, when the trigger device connection hierarchy is complex, each trigger device needs to have its trigger parameters configured separately to achieve synchronized triggering. However, currently, for multiple cascaded trigger devices, trigger parameter configuration must be performed separately for each device, and each device can only be configured independently, making the configuration process relatively complicated.

[0025] The second triggering device is used to control the synchronous triggering of the plurality of devices to be triggered in response to the trigger signal when the trigger parameters are configured.

[0067] An embodiment of the present application provides a synchronization system that can be applied to the upstream and downstream identification and automatic configuration of trigger parameters of any synchronization trigger device with specific and set decision threshold trigger requirements, such as synchronization trigger devices such as oscilloscope synchronizers, signal generators, spectrum analyzers, and radio frequency signal sources. It can be used for synchronization pulse trigger sampling control of oscilloscopes, spectrum analyzers, and other devices to be triggered, as well as upstream and downstream device status synchronization in other scenarios that require multi-level pulse signal transmission.

[0068] Figure 1 1 shows a schematic block diagram of a synchronization system consistent with at least one embodiment of the present application. As shown in the figure, the synchronization system 100 includes:

[0069] Multiple trigger devices; multiple trigger devices are connected via a transmission line 103;

[0070] Among them, the transmission line 103 transmits at least one of the following items between any two trigger devices: a trigger signal; a synchronization configuration request signal; a configuration signal containing trigger parameter information, so as to realize automatic synchronization of the trigger parameters of multiple trigger devices to the trigger parameters corresponding to the trigger parameter information based on the synchronization configuration request signal and the configuration signal; and in the case where the trigger parameters of multiple trigger devices are automatically synchronized, based on the trigger signal, multiple devices to be triggered connected to the multiple trigger devices are synchronized.

[0071] In the embodiment of the present application, the trigger parameters can use different names, such as signal trigger configuration parameters, signal trigger conditions, etc., and there is no restriction on the names here.

[0072] The trigger device can be referred to by various names, such as a synchronous trigger device, a synchronizer device, a synchronizer, a synchronous trigger source, or a pulse synchronization device, without limitation. A trigger device can be a device with single or multi-channel input and multi-channel output that can transmit pulse signals. The output channels can be connected to the device to be triggered or to other triggering devices. For example, the device to be triggered can be connected to the second trigger device 102 or to the first trigger device 101.

[0073] refer to Figure 1 Synchronization system 100 may include a first trigger device 101 and a second trigger device 102, which may form a variety of connection network topologies. The multiple trigger devices may be connected via transmission lines 103 to form a connection network topology including at least one of the following: star, cascade, tree, ring, or mesh.

[0074] Figure 2The following is a schematic block diagram of an example of a network topology structure for connecting a synchronization system according to an embodiment of the present application. As shown in the figure, in an exemplary embodiment, as a star-shaped network topology, first trigger devices 101 and second trigger devices 102 at different levels (multi-level) are connected in series. If there are more than two second trigger devices 102 at the same level, multiple second trigger devices 102 at the same level are connected in parallel. In this way, the first trigger device 101 and the second trigger device 102 can exchange configuration signals containing trigger parameter information. For example, the first trigger device 101 can configure the trigger parameters of the second trigger device 102. Second trigger device 102 can transmit a configuration request to first trigger device 101 via transmission line 103. First trigger device 101 can respond to the configuration request by sending a configuration signal containing trigger parameter information to second trigger device 102. This allows second trigger device 102 to be configured with the same trigger parameters as first trigger device 101 based on the configuration signal. Furthermore, under the control of the trigger signal sent by first trigger device 101 to second trigger device 102, first trigger device 101 and second trigger device 102 can synchronize sampling triggering for multiple connected measurement devices based on the trigger parameters. However, this is not a limitation; second trigger device 102 can also be used to automatically configure the trigger parameters of first trigger device 101. The principles are the same and will not be further elaborated.

[0075] Figure 3 The schematic diagram of the principle block diagram of the example 2 of the network topology structure of the synchronous system connection in the embodiment of the present application is shown. As shown in the figure, in an exemplary embodiment, as a cascade string type connection network topology, the first trigger device 101 and the second trigger device 102 at different levels are connected in series, and the second trigger devices 102 at different levels are also connected in series, thereby forming a series connection string cascaded into the first trigger device 101 and the second trigger device 102. In this way, by step-by-step transmission, it is possible to realize that the first trigger device 101 sends to the second trigger device 102, and then the second trigger device 102 sends a configuration signal containing trigger parameter information step by step downward, so that each level of the second trigger device 102 is also configured with a trigger parameter consistent with the first trigger device 101, thereby realizing synchronous sampling triggering of multiple measurement devices connected based on the trigger parameter. However, it is not limited to this. Any second trigger device 102 in the series connection string can also be used to automatically configure the trigger parameters of the first trigger device 101 and other second trigger devices 102. The principle is the same and will not be repeated here.

[0076] Then, in the first trigger device 101 and the second trigger device 102, the device that sends the configuration signal containing the trigger parameter information can be called the upstream device, and the device that sends the configuration request and receives the configuration signal can be called the downstream device. Figure 2 and Figure 3If the first trigger device 101 configures the trigger parameters of the second trigger device 102, the first trigger device 101 is the upstream device and the second trigger device 102 is the downstream device. Figure 3 If a second trigger device 102 configures the trigger parameters of another second trigger device 102 , then the first second trigger device 102 is an upstream device and the other second trigger device 102 is a downstream device.

[0077] In the embodiment of the present application, the transmission line 103 can be a single signal line, without the need for other communication cables, to enable transmission of trigger signals, synchronization configuration request signals, and configuration signals between any two trigger devices connected via the transmission line 103. The specific transmission method can be set according to actual needs to facilitate the identification of these signals. For example, the configuration signal can be transmitted regularly according to a preset timing sequence, or can be transmitted through negotiation, etc.

[0078] In the process of automatic synchronization of trigger parameters of multiple trigger devices, in order to ensure that the devices to be triggered can achieve synchronous sampling triggering, the two trigger devices can be configured with exactly the same trigger parameters, or they can be configured with trigger parameters with preset differences and not exactly the same, that is, trigger parameters corresponding to the trigger parameter information, so as to overcome the influence of time delay, signal attenuation, etc. caused by factors such as transmission lines on synchronous triggering.

[0079] In this way, the embodiment of the present application connects multiple trigger devices through a transmission line, and only needs to use the transmission line to transmit at least a trigger signal, a synchronization configuration request signal, and a configuration signal containing trigger parameter information between two trigger devices, thereby being able to use the transmission line to transmit the communication mode in reverse, realize automatic synchronization of the trigger parameters of the upstream and downstream trigger devices, and reduce the complexity of the trigger parameter configuration process; and based on the trigger parameter, it is possible to realize synchronous sampling triggering of multiple connected measurement devices. Therefore, through a single signal line, the trigger parameter configuration process can be realized on the basis of not introducing other external communication cables, which not only simplifies the user connection operation, but also greatly simplifies the operation of building complex topology connections.

[0080] In an optional embodiment, one of the any two triggering devices serves as an upstream device, and the other serves as a downstream device;

[0081] The upstream device is configured to send a configuration signal including trigger parameter information to the downstream device in response to the synchronization configuration request signal sent by the downstream device;

[0082] The downstream device is configured to send the synchronization configuration request signal to the upstream device; and configure the trigger parameters corresponding to the trigger parameter information in response to the configuration signal sent by the upstream device.

[0083] refer to Figure 1 、 Figure 2 and Figure 3 In an exemplary embodiment, first trigger device 101 can serve as an upstream device, and second trigger device 102 can serve as a downstream device. First trigger device 101 can send a trigger signal to second trigger device 102 via transmission line 103, and second trigger device 102 can also send a synchronization configuration request signal to first trigger device 101 via transmission line 103. This allows reverse communication via a single signal line (trigger cable) to enable the upstream trigger device 101 to identify the downstream trigger device 102, thus enabling upstream and downstream identification of cascaded trigger devices.

[0084] In addition, the first trigger device 101 responds to the synchronization configuration request signal sent by the second trigger device 102, and sends a configuration signal containing trigger parameter information to the second trigger device 102. The second trigger device 102 configures the trigger parameters corresponding to the trigger parameter information according to the configuration signal, thereby realizing automatic configuration of the trigger parameters of the downstream device according to the trigger parameters of the upstream device, and realizing a solution in which the downstream device automatically adapts and automatically synchronizes the trigger parameters of the upstream device.

[0085] In an exemplary embodiment, any triggering device in the synchronization system can act as an upstream device; or as a downstream device.

[0086] In an optional embodiment, the trigger device includes a level determination module and a signal transmission module;

[0087] Wherein, in the case where the triggering device is the upstream device, the level judgment module is used to receive and identify the synchronization configuration request signal sent by the downstream device, so that the triggering device responds based on the synchronization configuration request signal; the signal transmission module is used to send the configuration signal to the downstream device based on the response of the triggering device;

[0088] In the case where the trigger device is the downstream device, the level judgment module is used to receive and identify the configuration signal sent by the upstream device, so that the trigger device configures the trigger parameters based on the configuration signal; the signal transmission module is used to send the synchronization configuration request signal to the upstream device.

[0089] In the embodiment of the present application, the synchronization configuration request signal includes an analog signal or a digital signal;

[0090] The configuration signal includes an analog signal or a digital signal.

[0091] In some examples, the transmission line 103 is used to transmit analog signals, that is, the synchronization configuration request signal and the configuration signal are both analog signals. Figure 4 A schematic block diagram of a trigger device consistent with at least one embodiment of the present application is shown. As shown in the figure, the trigger device can be implemented by a processor module combined with peripheral circuits, etc.

[0092] In some possible implementations, the processor of the processor module may be a circuit with signal processing capabilities. In one implementation, the processor may be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor may implement certain functions through the logical relationship of a hardware circuit, and the logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable, such as a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the triggering of the device function. In addition, the processor can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.

[0093] In some possible implementations, the peripheral circuit may include at least one of the following: a comparison circuit, an analog-to-digital conversion circuit (ADC), a digital-to-analog conversion circuit (DAC), etc.

[0094] Figure 5A schematic block diagram illustrating a specific example of an input or output terminal of a trigger device in an embodiment of the present application is shown. As shown in the figure, in an exemplary embodiment, a first trigger device 101 of an upstream device may include a level determination module 11 and a signal transmission module 12, and may be provided at the output terminal of the upstream device. A second trigger device 102 of a downstream device may include a level determination module 21 and a signal transmission module 22, and may be provided at the input terminal of the downstream device.

[0095] The downstream device input-end signal transmission module 22 can initiate a request to the upstream device, namely, send a synchronization configuration request signal. Similarly, the upstream device output-end signal transmission module 12 can send a configuration signal to the downstream device. Therefore, in an exemplary embodiment, a circuit capable of level transmission, such as a DAC, can be added to the circuit that originally only has a trigger level (trigger signal) input.

[0096] The downstream device input terminal level determination module 21 can receive configuration signals sent by the upstream device and can also receive trigger signals. Similarly, the upstream device output terminal level determination module 11 can receive requests initiated by the downstream device. The level determination module can analyze the default input terminal level to identify the configuration signal or the synchronization configuration request signal. In an exemplary embodiment, a circuit capable of level comparison, such as an ADC or comparator, can be added to the circuit that originally only has a trigger level (trigger signal) input.

[0097] In this way, the embodiment of the present application realizes reverse communication from the downstream device to the upstream device through the transmission line (such as the trigger cable) to request trigger parameters by setting the level judgment module and the signal transmission module of the trigger device, thereby realizing automatic configuration of the trigger parameters of the downstream device. Structurally, a single signal line is used for upper and lower level verification, which is achieved without introducing other external communication cables, simplifying the user connection operation; and functionally, it can automatically determine the upper and lower level relationship of the trigger device, simplifying the user configuration process, and thus can be applied to the upstream and downstream parameter synchronization configuration of any trigger signal transceiver (i.e., trigger device) that is triggered by a specified trigger threshold.

[0098] In other examples, the transmission line 103 is used to transmit digital signals, that is, the synchronization configuration request signal and the configuration signal are both digital signals. Figure 6 A schematic block diagram of a specific example of a processor module in an embodiment of the present application is shown. As shown in the figure, the level judgment module and the signal transmission module included in the trigger device can be implemented by executing method instructions by the processor module.

[0099] Thus, illustratively, the request initiated by the downstream device can be a single pulse or a digital signal carrying information, which can be configured according to actual needs. In an exemplary embodiment, whether the synchronization configuration request signal is output as an active high level or an active low level can depend on whether the transmission line level is a default high level or a default low level, with the active level being the opposite of the default level.

[0100] The upstream device provides trigger parameter data to the downstream device, that is, sends a configuration signal containing trigger parameter information. The data transmission form can be an analog signal or a digital signal, which can be set according to actual needs.

[0101] In an optional implementation manner, the level value of the configuration signal is lower than the level value of the trigger signal.

[0102] To implement analog signal communication, the upstream device's signal transmission module can use only an analog-to-digital converter (DAC) to send a pulse signal with a level that matches a preset percentage of the trigger signal level. This means the configuration signal level is lower than the trigger signal level. The downstream device's level determination module can then distinguish between the trigger signal and the configuration signal by comparing the received signal levels.

[0103] In this way, the embodiment of the present application provides a configuration signal with a level value lower than the trigger signal level value, sets a preset percentage, and adopts a scheme of superimposing a level lower than the trigger signal level, thereby being able to distinguish between the configuration signal and the trigger signal, solve the problem of automatic identification of upstream and downstream devices in the cascade of trigger devices, and prevent false triggering of downstream devices.

[0104] In the embodiment of the present application, the trigger parameters may include trigger types such as edge trigger, pulse width trigger, code pattern trigger, etc.; trigger conditions such as rising edge, falling edge, etc.; and so on.

[0105] The embodiment of the present application also provides a measurement system, Figure 7 A schematic block diagram of a measurement system consistent with at least one embodiment of the present application is shown. As shown in the figure, the measurement system 1000 includes:

[0106] The synchronization system 100 as described in the above embodiment; and

[0107] Multiple devices to be triggered are used for synchronous triggering under the control of the synchronization system 100.

[0108] In the embodiments of the present application, the devices to be triggered may include oscilloscopes, spectrum analyzers, and other devices requiring state synchronization. The synchronization system 100 can perform synchronous pulse trigger sampling control on multiple devices to be triggered, and perform state synchronization in a multi-level pulse signal transmission scenario for other devices requiring state synchronization. Consequently, multiple devices to be triggered can be synchronously triggered under the control of a trigger signal to perform synchronous sampling or synchronous state updates.

[0109] Figure 8 The following is a schematic block diagram of a first example of a measurement system according to an embodiment of the present application. As shown in the figure, in an optional embodiment, the synchronization system 100 includes a first triggering device 101 and multiple second triggering devices 102; each of the second triggering devices 102 is connected to the first triggering device 101 via a transmission line 103; each of the second triggering devices 102 is connected to one or more of the devices to be triggered 200;

[0110] The first trigger device 101 is used to configure the trigger parameters of the plurality of second trigger devices 102 via the transmission line 103 so that the trigger parameters of each second trigger device 102 are consistent with the trigger parameters of the first trigger device 101; and send a trigger signal to the plurality of second trigger devices 102 via the transmission line 103 to achieve synchronous triggering of the plurality of devices to be triggered 200;

[0111] The second triggering device 102 is configured to control the synchronous triggering of the plurality of devices to be triggered 200 in response to the trigger signal when the trigger parameters are configured.

[0112] In this way, a single transmission line can be used to achieve automatic synchronous configuration of trigger parameters of upstream and downstream trigger devices, simplifying the configuration process, simplifying user connection operations, and ensuring the synchronization of trigger operations of the devices to be triggered.

[0113] refer to Figure 8 , the devices to be triggered 200 can all be connected to the second triggering device 102, but it is not limited thereto.

[0114] Figure 9 A schematic block diagram of a second example of a measurement system in an embodiment of the present application is shown. Figure 10 FIG. 1 shows a schematic block diagram of a third example of a measurement system in an embodiment of the present application. In other exemplary embodiments, as Figure 9 As shown, the device to be triggered 200 can also be connected to the first trigger device 101 and the second trigger device 102 respectively. Figure 10As shown, the first trigger device 101 and the second trigger device 102 may be connected in a cascaded network topology. It should be understood that other network topologies and other connection modes of the devices to be triggered may exist, which are not exhaustively listed here.

[0115] The embodiment of the present application also provides a parameter automatic synchronization method, which can be applied to downstream devices in the synchronization system 100. Figure 11 The following is a flow chart of Example 1 of the automatic parameter synchronization method according to an embodiment of the present application. As shown in the figure, the automatic parameter synchronization method includes:

[0116] S1001: Sending a synchronization configuration request signal;

[0117] S1002: Identify whether the acquired signal is a configuration signal including trigger parameter information sent by the upstream device in response to the synchronization configuration request signal;

[0118] S1003: If the configuration signal is obtained, trigger parameter configuration is performed based on the configuration signal.

[0119] In this way, if the configuration signal is not obtained, the downstream device can maintain the current state, or end after a certain period of time to complete the request, etc., which can be set according to actual needs.

[0120] In an optional implementation, step S1002 includes:

[0121] S10021: Identify whether the acquired signal is the configuration signal or a trigger signal;

[0122] S10022: If the trigger signal is obtained, the device to be triggered may be controlled to be triggered synchronously.

[0123] The embodiment of the present application also provides a parameter automatic synchronization method, which can be applied to the upstream device in the synchronization system 100. Figure 12 The following is a flow chart of Example 2 of the automatic parameter synchronization method according to an embodiment of the present application. As shown in the figure, the automatic parameter synchronization method includes:

[0124] S2001: Identify whether the acquired signal is a synchronization configuration request signal sent by a downstream device;

[0125] S2002: If the synchronization configuration request signal is obtained, a configuration signal including trigger parameter information is sent to the downstream device.

[0126] In this way, the upstream device can respond to the trigger parameter synchronization request of the downstream device and configure the trigger parameters of the downstream device, so that the downstream device in the reverse communication mode of the trigger cable can automatically adapt to the trigger parameters of the upstream device.

[0127] If no synchronization configuration request signal is obtained, the upstream device can maintain the current state, etc., and can be set according to actual needs.

[0128] In an optional implementation, step S2001 includes:

[0129] S20011: Identify whether the acquired signal is the synchronization configuration request signal or a trigger signal;

[0130] S20012: If the trigger signal is obtained, the device to be triggered may be controlled to be triggered synchronously.

[0131] The synchronization configuration request signal, configuration signal, and trigger signal can be identified based on their level values. The level determination module can be used to implement the identification steps in S1002 or S2001. For example, for analog signals, a comparator can be used for level determination; or an ADC can be used to convert the signals into digital signals and send them to a processor module, which then executes method instructions for identification. For digital signals, the processor module can directly execute method instructions for identification.

[0132] In some examples, the processor module may include an automatic parameter synchronization device for a downstream device in the synchronization system, and the automatic parameter synchronization device may include:

[0133] The first module is used to send a synchronization configuration request signal;

[0134] The second module is configured to identify whether the acquired signal is a configuration signal containing trigger parameter information and sent by the upstream device in response to the synchronization configuration request signal;

[0135] The third module is configured to perform trigger parameter configuration based on the configuration signal if the configuration signal is obtained.

[0136] In other examples, the processor module may further include an automatic parameter synchronization device applied to an upstream device in the synchronization system. The automatic parameter synchronization device may include:

[0137] The fourth module is used to identify whether the acquired signal is a synchronization configuration request signal sent by the downstream device;

[0138] The fifth module is configured to send a configuration signal including trigger parameter information to the downstream device if the synchronization configuration request signal is obtained.

[0139] It should be understood that the division of the various units or modules in the above-described apparatus is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a single physical entity, or they may be physically separate. Furthermore, the units or modules in the apparatus may be implemented in the form of a processor invoking software: for example, the apparatus includes a processor connected to a memory storing instructions, and the processor invokes the instructions stored in the memory to implement any of the above-described methods or the functions of the various units or modules in the apparatus.

[0140] The embodiment of the present application also provides a synchronous measurement method, which can be applied to the measurement system 1000. Figure 13 A flow chart of a specific example of a synchronous measurement method in an embodiment of the present application is shown. As shown in the figure, the synchronous measurement method includes:

[0141] S100: A configuration signal containing trigger parameter information is transmitted between multiple trigger devices of a measurement system via a transmission line, so that trigger parameters of a downstream device among the multiple trigger devices are automatically adapted to be consistent with trigger parameters of an upstream device;

[0142] S200: A trigger signal is transmitted between multiple trigger devices via a transmission line, so that under the control of the trigger signal, multiple devices to be triggered connected to the trigger device are synchronously triggered.

[0143] In an optional implementation, step S100 may be implemented by the above-mentioned automatic parameter synchronization method applied to the upstream device and the automatic parameter synchronization method applied to the downstream device.

[0144] In this way, the embodiment of the present application realizes a solution in which the downstream device automatically adapts to the trigger parameters of the upstream device by triggering the reverse communication mode of the cable, thereby reducing the complexity of the configuration parameters.
