Background
For a conventional simulation circuit, the simulation circuit generally includes a plurality of circuit boards, an output signal of a previous circuit board is used as an input signal of a next circuit board, and the next circuit board performs control, signal processing, and the like according to the input signal. Due to mutual interference of components in the circuit board, interference of surrounding environment and difference of control modes, signals output by the board A are inconsistent with target signals, and the target circuit signals are input signals which enable the board B to operate according to normal logic. Therefore, when the output signal of the board a is inaccurate, the normal operation of the board B is affected, and the board B cannot meet the requirement of control precision.
In the practical application process, the precision requirement of some products on input and output signals in the circuit board is very high, so that the simulation circuit board is usually tested before the products are put on line to ensure the normal operation of the simulation circuit board. In the related art, when the signal from the a board is inconsistent with the target signal required by the B board, the B board usually corrects the output signal from the a board, and the corrected signal is used as the input signal of the B board, for example, by using a function fitting method. However, this kind of correction method is generally low in accuracy, the B board cannot obtain an accurate input signal faster and more efficiently, and the operation load of the B board is increased, which affects the operation of the actual function of the B board.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
First, an example of an applicable scenario in the embodiment of the present invention is described: taking a simulation system as an example, a simulation circuit generally includes a plurality of circuit boards, an output signal of a previous circuit board is used as an input signal of a next circuit board, and the next circuit board performs operation of each module according to the input signal. The circuit in the former circuit board is referred to as a first circuit and the circuit in the latter circuit board is referred to as a second circuit, and the number of the first circuit and the second circuit is not limited.
Fig. 1 is a flowchart of a circuit signal conditioning method according to an embodiment of the present invention, where the method may be performed by a first circuit according to an embodiment of the present invention, and the first circuit may be implemented in software or hardware. Referring to fig. 1, the method may specifically include the following steps:
s101, the first circuit outputs a circuit signal according to a set value of the first circuit, and the circuit signal serves as an input signal of the second circuit.
Taking the above two circuit boards as an example, since the input signal of the second circuit is derived from the output signal of the first circuit, a target output value is usually set, and if the input signal of the second circuit is the same as the target output value or sufficiently close to the target output value, the second circuit can operate normally according to its own control logic. The first circuit is caused to output as an input signal to the second circuit at a target output value by adjusting a parameter in the first circuit, the adjustable parameter being referred to as a set value.
Specifically, the first circuit includes a plurality of components, each of which constitutes a plurality of functional blocks, and during the simulation, the first circuit operates according to its own control logic based on the set value, thereby outputting a circuit signal. The circuit signals output are usually different depending on the setting values. The output circuit signal is used as the input signal of the second circuit, so whether the output circuit signal accurately and directly influences whether the second circuit can normally operate or not. In a specific example, the initial value of the setting value may be a target output value, which reduces the amount of computation compared to a random value of the initial value of the setting value, and enables the output circuit signal to approach the target output value more quickly.
Optionally, the circuit signal includes: a voltage signal, or, a current signal. When the input signal required by the second circuit is a voltage signal, the first circuit can be controlled to output the voltage signal, or a current signal output by the first circuit is converted into the voltage signal; when the input signal required by the second circuit is a current signal, the first circuit can be controlled to output the current signal, or a voltage signal output by the first circuit is converted into the current signal.
S102, the first circuit obtains an actual output value of the circuit signal.
Specifically, after the first circuit outputs the circuit signal according to the set value, the first circuit obtains an actual output value of the circuit signal, and the detection module in the first circuit may be used to obtain the actual output value in general. For example, the target output value is 3V, the initial value of the set value is 3V, and the actual output value of the first circuit detection circuit signal is 2.5V. In an actual operation process, after each adjustment of the setting value, an adjusted circuit signal is usually obtained, where one of the adjusted circuit signals is used for example and is not specifically limited.
S103, when the actual output value and the preset target output value do not meet the preset relation, the first circuit adjusts the set value so as to output the adjusted circuit signal according to the adjusted set value until the actual output value and the target output value meet the preset relation.
Optionally, the preset relationship may be set in a manner that an actual output value of a circuit signal output by the first circuit is used as an input signal of the second circuit, and the second circuit can normally operate.
Specifically, each time the first circuit obtains an output value, the first circuit compares the magnitude relationship between the actual output value and a preset target output value, and when the comparison result does not satisfy the preset relationship, it indicates that the actual output value of the first circuit cannot enable the second circuit to normally operate if the actual output value is used as the input value of the second circuit. In this case, the setting value may be adjusted specifically according to the comparison result, for example, if the actual output value is smaller than the target output value, the setting value is increased, and if the actual output value is larger than the target output value, the setting value is decreased. And then the first circuit outputs the adjusted circuit signal according to the adjusted set value, and if the adjusted circuit signal still does not meet the preset relation, the adjustment is continued until the actual output value and the target output value meet the preset relation. The actual output value obtained at this time can be used as the input signal of the second circuit to control the second circuit to normally operate.
Optionally, the preset relationship includes: the ratio of the actual output value to the target output value is within a preset range, or the absolute value of the difference between the actual output value and the target output value is within a preset range.
In one specific example, the actual output value is denoted as MFruit of Chinese wolfberryLet the target output value be MEyes of a userThe set value is recorded as MIs provided withThe initial value of the set value is the initial set value. Wherein the ratio of the actual output value to the output value is within a preset range, and the preset range can be95% to 100%; the absolute value of the difference between the actual output value and the target output value is within a predetermined range, which may be 0.05MEyes of a user. The preset relationship can be adjusted according to the actual operation condition of the second circuit, for example, when some components are added to the second circuit, the control logic of the whole circuit changes, which also results in the need of adjusting the preset range.
According to the technical scheme, the circuit signal is output through the first circuit according to the set value of the first circuit and serves as the input signal of the second circuit, and then the second circuit controls the work of each component in the second circuit by applying the circuit signal; the first circuit obtains the actual output value of the circuit signal and compares the actual output value with a preset target output value, and when the actual output value and the preset target output value do not meet the preset relationship, the set value is adjusted, so that the first circuit outputs the adjusted circuit signal according to the adjusted set value until the actual output value and the target output value meet the preset relationship. Therefore, the circuit signal of the adjusted actual output value which meets the preset relation is used as the input signal of the second circuit, so that the problems of second circuit load increase and low accuracy rate caused by the execution of the second circuit in the adjusting process are solved, and the control accuracy of the second circuit is improved by improving the accuracy of the input signal of the second circuit.
Fig. 2 is a flowchart of another circuit signal adjusting method according to an embodiment of the present invention, which is implemented on the basis of the above embodiments. Referring to fig. 2, the method may specifically include the following steps:
s201, the first circuit outputs a circuit signal according to a set value of the first circuit, and the circuit signal is used as an input signal of the second circuit.
Optionally, the number of the second circuits is at least one, and each second circuit corresponds to one circuit signal. When one second circuit is used, one circuit of circuit signals output by the first circuit corresponds to the second circuit; when the second circuit is multiple, there are multiple paths in the circuit signal output by the first circuit corresponding to the second circuit. In a specific example, the second circuits are multiple circuits, and each second circuit may implement a different function, so that its internal control logic may also be different, and thus a plurality of second circuits need to be provided, and multiple circuit signals corresponding to the second circuits need to be output from the first circuit.
And S202, if one second circuit is provided, the first circuit detects the actual value of one circuit signal corresponding to the second circuit, and takes the detected actual value as the actual output value of the circuit signal.
Specifically, if one second circuit is used, it indicates that a certain circuit signal in the first circuit corresponds to the second circuit, the first circuit detects an actual value of the circuit signal corresponding to the second circuit, the detected actual value can be used as an actual output value of the circuit signal, and the first circuit does not need to detect actual values of other circuit signals.
And S203, if the number of the second circuits is multiple, the first circuit respectively detects the actual value of one circuit signal corresponding to each second circuit to obtain multiple actual values, and calculates the actual output value of the circuit signal according to the multiple actual values.
Specifically, if a plurality of second circuits are provided, which indicates that some circuit signals in the first circuit correspond to the second circuits, the first circuit detects actual values of the circuit signals corresponding to the second circuits, that is, the first circuit detects actual values of one circuit signal corresponding to each second circuit, so as to obtain a plurality of actual values. And then, calculating the plurality of actual values to obtain the actual output value of the circuit signal. The operation process can avoid errors caused by accidental factors, and further, an actual output value closer to a real situation is obtained by calculating a plurality of actual values.
It should be noted that, in the two different cases where one or more second circuits are used in S202 and S203, the first circuit respectively performs different operations, and there is no obvious precedence relationship between these two steps, which is only used for illustration in fig. 2.
And S204, when the actual output value and the preset target output value do not meet the preset relation, the first circuit calculates the difference value between the target output value and the actual output value, and takes the difference value as a compensation value.
When the actual output value of the first circuit and the preset target output value do not meet the preset relationship, it is indicated that the actual output value cannot be directly applied as an input signal of the second circuit, but needs to be adjusted. Therefore, the actual output value of the first circuit is to be adjusted by adjusting the set value. Specifically, the difference between the target output value and the actual output value is calculated, and the difference is used as a compensation value which is recorded as deltaSupplement deviceThen ΔSupplement device＝MEyes of a user-MFruit of Chinese wolfberry. The compensation value is used to compensate the set value so that the actual output value is closer to the target output value.
S205, adjusting the set value according to the target output value and the compensation value so as to output the adjusted circuit signal according to the adjusted set value until the actual output value and the target output value meet the preset relation.
In a specific example, a ratio coefficient between the target output value and the actual output value is called a control coefficient, and the compensation value is multiplied by the control coefficient, and the target output value is added to the control coefficient, so that the adjusted set value is obtained. The adjusted set value is recorded as MSetting tone＝MEyes of a user+△Supplement device*MEyes of a user/MFruit of Chinese wolfberry. And then outputting the adjusted circuit signal according to the adjusted set value, and if the adjusted circuit signal cannot meet the preset relationship after once adjustment, continuing to adjust according to the principle until the actual output value and the target output value meet the preset relationship.
And S206, when the actual output value and the target output value meet the preset relation, the first circuit outputs a circuit signal to the second circuit.
Specifically, the first circuit outputs a circuit signal to the second circuit when the actual output value and the target output value satisfy a preset relationship. The condition that the preset relationship is satisfied can include two conditions, the first condition can be that the actual output value of the first circuit satisfies the preset relationship with the target output value without any adjustment, and the circuit signal can be directly output to the second circuit; in the second case, the actual output value is output by the adjusted set value, and the circuit signal of the adjusted actual output value is output to the second circuit.
In a specific example, the first circuit may include an output selection switch, the output selection switch is in a normally-closed state, that is, the first circuit and the second circuit are not connected, when the actual output value and the target output value satisfy a preset relationship, the output selection switch is turned on, the first circuit and the second circuit are connected, and the first circuit outputs a circuit signal of the actual output value to the second circuit.
In addition, in the technical solution of the present application, the method may further include: when the first circuit generates a circuit signal, the first circuit outputs the circuit signal to the second circuit.
For example, the embodiment of the present application may further include another case where the first circuit and the second circuit are in a connected state, so that when the first circuit generates a circuit signal, the first circuit outputs the circuit signal to the second circuit in real time. Thus, the second circuit can determine whether the circuit signal can be used as the input signal of the second circuit.
In this embodiment of the application, when there is one second circuit, the first circuit may directly use an actual value of a detected one-way circuit signal corresponding to the second circuit as an actual output value of the circuit signal; when a plurality of second circuits are provided, in order to reduce errors caused by accidental factors, the actual output value of the circuit signal can be obtained by calculating the actual value of one circuit signal corresponding to each second circuit detected by the first circuit, so that the accuracy of the actual output value can be improved; when the actual output value and the target output value do not meet the preset relationship, the difference value of the actual output value and the target output value is calculated to serve as a compensation value to compensate the set value, and then the adjusted signal is output according to the adjusted set value, so that the actual output value is closer to the target output value; and when the actual output value and the target output value meet the preset relation, the circuit signal is output to the second circuit as an input signal, so that the second circuit can normally operate by applying the adjusted actual output value.
Fig. 3 is a flowchart of another circuit signal conditioning method according to an embodiment of the present invention, which is implemented on the basis of the above embodiments. Referring to fig. 3, the method may specifically include the following steps:
and S301, the first circuit outputs a circuit signal according to a set value of the first circuit, and the circuit signal is used as an input signal of the second circuit.
And S302, if the number of the second circuits is one, the first circuit detects the actual value of one circuit signal corresponding to the second circuit, and takes the detected actual value as the actual output value of the circuit signal.
And S303, if the number of the second circuits is multiple, the first circuit circularly detects the actual value of one circuit signal corresponding to each second circuit by adopting the same detection module, wherein only one circuit signal is detected each time during circular detection to obtain multiple actual values.
Specifically, the detection module may be configured to detect an actual output value of the first circuit, and if there are a plurality of second circuits, the same detection module is used to cyclically detect an actual value of one circuit signal corresponding to each second circuit, and only one circuit signal is detected each time in a cyclic detection process. A cycle detection number or cycle detection period may be provided, for example, the cycle detection number may be the same as or different from the number of the second circuits, and the cycle detection number is usually greater than or equal to the number of the second circuits. Illustratively, the number of times of the loop detection is set to 11, so that the same detection module can be applied to detect 11 times to obtain an actual value of one circuit signal corresponding to each second circuit.
Optionally, a specific implementation manner of loop detection may include: and controlling one circuit signal corresponding to each second circuit to be circularly communicated through the multi-path selection switch, and detecting the actual value of the currently communicated circuit signal, wherein only one circuit signal is communicated when the circuits are circularly communicated each time.
The multiple-path selection switch takes the optical coupling switch as an example, each path of circuit signal corresponds to one optical coupling switch, and the optical coupling switches on and off to control one path of circuit signal corresponding to each second circuit to be circularly communicated, namely, which path of circuit signal is selected. In a specific example, for example, there are 5 second circuits, 5 output channels in the first circuit output 5 circuit signals, the circuit signals are exemplified by analog quantities, 1 represents that the optical coupler is closed, and 0 represents that the optical coupler is opened, so that the optical coupler can be controlled by 00001, 00010, 00100, 01000 and 10000 in the multi-way selector switch, and the circuit signal output by each channel is cyclically detected.
Illustratively, S303 may be replaced by the following steps as an alternative embodiment: if the number of the second circuits is multiple, the first circuit respectively adopts different detection modules to detect the actual value of one circuit signal corresponding to each second circuit, so as to obtain multiple actual values. Specifically, if there are a plurality of second circuits, the first circuit may use different detection modules to detect an actual value of one path of signal corresponding to each second circuit, in this case, the number of the detection modules may be the same as or different from the number of the second circuits; one detection module may detect an actual value of only one circuit signal corresponding to one second circuit, and one detection module may also detect actual values of two circuit signals corresponding to two second circuits, which are used as examples and do not form specific limitations, so that a plurality of actual values may be obtained.
S304, calculating the average value of the actual values, and taking the average value of the actual values as the actual output value of the circuit signal.
When there are a plurality of second circuits, the first circuit detects a plurality of actual values, so that an average value of the plurality of actual values can be calculated, for example, when 11 actual values are obtained, the 11 actual values are summed, and then the sum is divided by 11 to obtain an average value of the 11 actual values. This average value is taken as the actual output value of the circuit signal.
Illustratively, S304 may also be replaced by the following steps as an optional implementation: the maximum value and the minimum value are removed from the plurality of actual values, an average value of the remaining actual values is calculated, and the average value of the remaining actual values is used as an actual output value of the circuit signal. Specifically, in calculating the actual output value, in order to avoid an error due to an accidental factor, the maximum value and the minimum value may be removed from the actual values, and an average value of the remaining actual values may be calculated. In a specific example, the target output value is 3V, and the 11 actual values are 2.51V, 2.63V, 2.75V, 2.84V, 2.95V, 2.81V, 3.12V, 3.74V, 3.25V, 3.05V and 3.27V, respectively, then the maximum value of 3.74V and the minimum value of 2.51V are likely to be errors due to accidental factors, so that the two values are removed, and the average value of the remaining actual values is used as the actual output value of the circuit signal, thereby improving the accuracy in the actual output value correction process.
S305, when the actual output value and the preset target output value do not meet the preset relation, the first circuit calculates the difference value between the target output value and the actual output value, and takes the difference value as a compensation value.
S306, adjusting the set value according to the target output value and the compensation value so as to output the adjusted circuit signal according to the adjusted set value until the actual output value and the target output value meet the preset relation.
And S307, when the actual output value and the target output value meet the preset relation, the first circuit outputs a circuit signal to the second circuit.
In the embodiment of the application, when a plurality of second circuits are provided, the first circuit can detect the actual value of the circuit signal of the first circuit in different modes, one mode is to adopt the same detection module for circular detection, the detection method has lower requirements on the detection module, the use of related pins in the detection module can be reduced, and the detection speed is improved; the other mode is that different detection modules are adopted to respectively detect the actual value of one circuit signal corresponding to each second circuit, so that the detection method has simple detection logic and is not easy to make mistakes; in addition, the operation of averaging a plurality of actual values is used as an actual output value, so that errors caused by accidental factors can be avoided, and the accuracy of detection of the actual output value is further improved.
Fig. 4 is a schematic structural diagram of a first circuit according to an embodiment of the present invention, where the first circuit is suitable for implementing a circuit signal conditioning method according to an embodiment of the present invention. As shown in fig. 4, the first circuit 40 may specifically include: a signal output module 401, an acquisition module 402 and an adjustment module 403.
The signal output module 401 is configured to output a circuit signal according to a set value in a first circuit, where the circuit signal is used as an input signal of a second circuit; an obtaining module 402, configured to obtain an actual output value of the circuit signal; an adjusting module 403, configured to adjust the set value when the actual output value and the preset target output value do not satisfy the preset relationship, so that the signal output module outputs the adjusted circuit signal according to the adjusted set value until the actual output value and the target output value acquired by the acquiring module satisfy the preset relationship.
According to the technical scheme, the circuit signal is output through the first circuit according to the set value of the first circuit and serves as the input signal of the second circuit, and then the second circuit controls the work of each component in the second circuit by applying the circuit signal; the first circuit obtains the actual output value of the circuit signal and compares the actual output value with a preset target output value, and when the actual output value and the preset target output value do not meet the preset relationship, the set value is adjusted, so that the first circuit outputs the adjusted circuit signal according to the adjusted set value until the actual output value and the target output value meet the preset relationship. Therefore, the circuit signal of the adjusted actual output value which meets the preset relation is used as the input signal of the second circuit, so that the problems of second circuit load increase and low accuracy rate caused by the execution of the second circuit in the adjusting process are solved, and the control accuracy of the second circuit is improved by improving the accuracy of the input signal of the second circuit.
For example, fig. 5 shows a schematic structure of another first circuit. As shown in fig. 5, the first circuit may specifically include: the device comprises a signal output module 401, an acquisition module 402, an adjustment module 403, an output selection switch 404, a detection module 405 and a multi-way selection switch 406. Fig. 5 shows only one case where the circuit signals are multiplexed and the detection module is one for illustration, and other cases are not shown, which is described in detail with reference to the embodiments.
The output selection switch 404 is connected to the signal output module 401 and the second circuit 50, and configured to connect the signal output module 401 and the second circuit to output a circuit signal from the first circuit to the second circuit when the actual output value and the target output value satisfy a preset condition.
Specifically, the first circuit in the embodiment of the present application may further include an output selection switch 404. The output selection switch 404 is connected to the signal output module 402 and the second circuit 50, and controls the signal output module 401 to be connected to the second circuit when the actual output value and the target output value satisfy a predetermined condition, and after the actual output value and the target output value are connected to each other, the first circuit outputs a circuit signal from the first circuit to the second circuit.
In addition, the signal output module 401 can be directly connected to the second circuit 50, so that the first circuit outputs the circuit signal to the second circuit in real time without waiting for the output selection switch to be turned on when the first circuit generates the circuit signal. Thus, the second circuit can determine whether the circuit signal can be used as the input signal of the second circuit.
Optionally, the circuit signal is one or more paths, and the first circuit further includes: a detecting module 405, configured to detect an actual value of each circuit signal, so that the obtaining module 402 obtains an actual output value of the circuit signal according to the actual value.
Optionally, if the circuit signals are multiple paths, the number of the detection modules 405 is multiple, and each detection module 405 corresponds to one path of circuit signal to detect an actual value of the corresponding circuit signal; alternatively, the number of the detection modules 405 is one, and the first circuit further includes: a multiplexer 406, the multiplexer 406 being configured to select the circuit signal communicated to the detection module 405 to cyclically detect the actual value of each circuit signal through the detection module 405.
Specifically, when the circuit signals are multiplexed and the detection modules 405 are multiple, each detection module 405 may be applied to detect an actual value of the corresponding circuit signal; when the circuit signals are multiple paths and the detection module 405 is one, the selection and detection module 405 can be controlled to communicate with which circuit signal at each moment through the multiple-path selection switch 406, so that the actual value of each circuit signal can be detected circularly.
Optionally, the multiple-way selection switch 406 is an optical coupler switch, and each circuit signal corresponds to one optical coupler switch. The multiple-path selection switch 406 may be an optical coupler switch, each path of circuit signal corresponds to one optical coupler switch, and which paths of circuit signals are controlled and selected by opening and closing the optical couplers.
