[0001] This invention relates to the field of component selection technology, and in particular to a method, apparatus, equipment and medium for determining components of a logic prototype. Background Technology

[0002] With the rapid development of rail transit equipment systems, people have put forward higher requirements for the accuracy and efficiency of component selection and verification. Traditional verification methods involve manual selection of various components. However, the control circuit of the whole vehicle involves a wide variety and a large number of components. Therefore, manual selection is labor-intensive, time-consuming, and easily affected by human factors, resulting in low selection accuracy.

[0003] Therefore, improving the efficiency and accuracy of component selection is a technical problem that urgently needs to be solved by those in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a method, apparatus, equipment, and medium for determining components in a logic prototype, so as to solve the technical problems of low efficiency and low accuracy in component selection.

[0005] To address the aforementioned technical problems, this invention provides a method for determining the components of a logic prototype, comprising:

[0006] Obtain the device load and components to be verified in the logic prototype;

[0007] The component to be verified is matched with standard characteristic parameters, and the device load is matched with device load characteristic parameters; wherein, the standard characteristic parameters and the device load characteristic parameters are parameters pre-stored in the logic prototype;

[0008] After a match is detected, the loop parameters of the component to be verified in the current loop of the logic prototype are obtained; wherein, the loop parameters are determined based on the current characteristics of the device load and the device load characteristic parameters that the device load matches.

[0009] The selection of the component to be verified is determined according to the verification rules between the standard characteristic parameters and the loop parameters of the component to be verified, which are pre-stored in the logic prototype.

[0010] Preferably, the step of matching the component to be verified with the standard characteristic parameters includes:

[0011] Obtain the model number of the component to be verified;

[0012] Obtain a target component with the same model as the component to be verified from the component parameter library of the logic prototype;

[0013] The component to be verified is matched with the standard characteristic parameters corresponding to the target component.

[0014] Preferably, matching the device load to the device load characteristic parameters includes:

[0015] Obtain the device details of the device load; wherein, the device details include at least the device model, connector code, and pin number;

[0016] The target device load is determined from the device load parameter library of the logic prototype based on the device details.

[0017] The device load is matched with the device load characteristic parameters corresponding to the target device load.

[0018] Preferably, before obtaining the loop parameters of the component to be verified in the current loop of the logic prototype, the method further includes:

[0019] If, within a preset time period, it is detected that the component to be verified matches the standard characteristic parameter, or that the device load matches the device load characteristic parameter, no component to be verified that does not match the standard characteristic parameter or no device load that does not match the device load characteristic parameter is detected, then the step of obtaining the loop parameter of the component to be verified in the current loop of the logic prototype is entered.

[0020] From the moment the component to be verified is detected to match the standard characteristic parameters, or from the moment the device load is detected to match the device load characteristic parameters, if within the preset time period, a component to be verified that does not match the standard characteristic parameters or a device load that does not match the device load characteristic parameters is detected, then it is determined whether there is a list of components to be verified that do not match the standard characteristic parameters in the component parameter library of the logic prototype, or whether there is a list of device loads that do not match the device load characteristic parameters in the device load parameter library of the logic prototype.

[0021] If not, add the details of the component to be verified that does not match the standard characteristic parameters to the component parameter library, or add the details of the device load that does not match the device load characteristic parameters to the device load parameter library; and proceed to the steps of matching the component to be verified with the standard characteristic parameters and matching the device load with the device load characteristic parameters.

[0022] If so, re-enter the steps of matching the component to be verified with the standard characteristic parameters and matching the device load with the device load characteristic parameters.

[0024] Set the rated current attribute of the pins of the device load;

[0025] Starting from the simulation of the current circuit, obtain the pins whose pin states have changed among all the pins of the device load;

[0026] If a pin whose pin state has changed is detected to have the rated current attribute, then update the current value of the direct connection line where the pin whose pin state has changed is located.

[0027] After the simulation is completed, the voltage value of each contact point, the minimum current value among all operating conditions, and the maximum current value among all operating conditions are obtained.

[0028] Alternatively, starting from the simulation of the current circuit, if a contact is detected to be open, the current value of the direct connection line where the pin on the energized side is located is updated; and the process proceeds to the step of obtaining the voltage value of each contact, the minimum current value among all operating conditions, and the maximum current value among all operating conditions after the simulation is detected to be closed.

[0029] Preferably, updating the current value of the directly connected line includes:

[0030] Obtain the current value and information of each power pin in the direct connection line;

[0031] If the power pin is a contact pin, obtain the current value of the contact pin;

[0032] The current value of the contact pin is updated from the current value to either the minimum current value or the maximum current value among all operating conditions, based on the relationship between the current value and the minimum current value or the maximum current value among all operating conditions, in order to update the current value of the direct connection line.

[0033] Preferably, after updating the current value of the directly connected line, the method further includes: obtaining the update time of the current value;

[0034] After detecting the end of the simulation and obtaining the voltage value of each contact, the minimum current value among the current values ​​corresponding to all operating conditions, and the maximum current value among the current values ​​corresponding to all operating conditions, the method further includes:

[0036] To address the aforementioned technical problems, the present invention also provides a component determination device for a logic prototype, comprising:

[0037] The first acquisition module is used to acquire the device load and the components to be verified in the logic prototype;

[0038] The matching module is used to match the component to be verified with standard characteristic parameters and to match the device load with device load characteristic parameters; wherein, the standard characteristic parameters and the device load characteristic parameters are parameters pre-stored in the logic prototype;

[0039] The second acquisition module is used to acquire the loop parameters of the component to be verified in the current loop of the logic prototype after a match is detected; wherein the loop parameters are determined based on the current characteristics of the device load and the device load characteristic parameters matched by the device load.

[0040] The determination module is used to determine the selection of the component to be verified based on the verification rules between the standard characteristic parameters and the loop parameters of the component to be verified, which are pre-stored in the logic prototype.

[0042] Memory, used to store computer programs;

[0043] A processor is used to implement the steps of the above-described method for determining the components of a logic prototype when executing the computer program.

[0044] To address the aforementioned technical problems, the present invention also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the above-described method for determining the components of a logic prototype.

[0045] The component determination method for a logic prototype provided by this invention includes: acquiring the device load and the component to be verified in the logic prototype; matching the component to be verified with standard characteristic parameters and matching the device load with device load characteristic parameters; after detecting a match, acquiring the loop parameters of the component to be verified in the current loop of the logic prototype; wherein the loop parameters are determined based on the current characteristics of the device load and the device load characteristic parameters matched to the device load; and determining the selection of the component to be verified according to the verification rules between the standard characteristic parameters and the loop parameters of the component to be verified pre-stored in the logic prototype. Compared with the previous method of manually selecting components, the method provided by this invention pre-stores standard characteristic parameters and device load characteristic parameters in the logic prototype, enabling the matching of parameters between components and device load to be verified within the logic prototype. After obtaining the loop parameters, since the logic prototype has pre-stored the verification rules between the standard characteristic parameters of the components to be verified and the loop parameters, the logic prototype can directly and automatically complete the verification of the component selection according to the verification rules, which greatly improves the efficiency of component selection.

[0056] 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 of ordinary skill in the art without creative effort are within the protection scope of the present invention.

[0057] The core of this invention is to provide a method, apparatus, equipment, and medium for determining components of a logic prototype, so as to solve the technical problems of low efficiency and low accuracy in component selection.

[0058] The application scenarios of the component selection method provided by this invention are not limited. For example, if the vehicle-level control circuit involves a wide variety and large number of components, the method provided by this invention can be used to automatically select components, thereby improving the efficiency and accuracy of component selection.

[0059] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Figure 1 A flowchart illustrating a method for determining components in a logic prototype, as provided in an embodiment of the present invention, is shown below. Figure 1 As shown, the method includes:

[0060] S10: Obtain the device load and components to be verified in the logic prototype;

[0061] S11: Match the components to be verified with standard characteristic parameters and match the device load with device load characteristic parameters; wherein, the standard characteristic parameters and the device load characteristic parameters are parameters that are pre-stored in the logic prototype;

[0062] S12: After a match is detected, obtain the loop parameters of the component to be verified in the current loop of the logic prototype; wherein, the loop parameters are determined based on the current characteristics of the device load and the device load characteristic parameters that match the device load.

[0063] S13: Determine the selection of the component to be verified based on the verification rules between the standard characteristic parameters and loop parameters of the component to be verified, which are pre-stored in the logic prototype.

[0064] A pre-built logic prototype is acquired, and its components are automatically identified and categorized according to predefined rules, such as relay coils, relay contacts, contactor coils, contactor contacts, circuit breakers, and switch contacts. The components to be verified are not limited and are determined based on the actual situation. While component parameter matching can be done manually, given the large number of components involved in the vehicle-level control circuit, to improve the efficiency of parameter matching, in one embodiment, the standard characteristic parameters for matching the components to be verified include:

[0065] Obtain the model number of the component to be verified;

[0066] Obtain the target component with the same model number as the component to be verified from the component parameter library of the logic prototype;

[0067] Match the component to be verified with the standard characteristic parameters corresponding to the target component.

[0068] Specifically, the detailed list of components to be verified is imported into the logic prototype. This list includes component models, which can be matched with models in the component parameter library. This allows for automatic retrieval of parameters for components of the same model from the library based on the component model. The component parameter library contains component models and characteristic parameters. Components in the logic prototype are queried for their characteristic parameters from the component parameter library based on their model, enabling automatic retrieval of parameters for components of the same model from the library based on the component model. For example, the relay parameter library contains the following parameters: Model: RZDR-1; Coil: Rated voltage (V) DC110, fluctuation range 70%~110%, Minimum pull-in voltage (V): 77, Release voltage (V): 11, Withstand voltage (V): 1500, Resistance (Ω): 4700; Contact: Rated voltage (V): DC110, Rated current (A): 0.5, Minimum current (mA): 1. In implementation, one or more parameters can be verified according to the verification rules. When the model of the relay to be verified is RZDR-1, the relay with model number RZDR-1 is found in the component parameter library as the target component. The parameters of the relay to be verified are matched with those of the relay with model number RZDR-1 in the component parameter library to achieve the matching of the parameters of the component to be verified.

[0069] Similarly, in implementation, matching the equipment load to the equipment load characteristic parameters includes:

[0070] Obtain the device details of the device load; the device details shall include at least the device model, connector code, and pin number;

[0071] The target equipment load is determined from the equipment load parameter library of the logic prototype based on the equipment details;

[0072] Match the device load to the device load characteristic parameters corresponding to the target device load.

[0073] Configure a device load parameter library. The feature library contains the device model and the load characteristics corresponding to the input and output interfaces, such as the current and voltage characteristics corresponding to each connector pin. Import the device details into the logic prototype. The device details include the device model, connector code, and pin number, which can be matched with the model, connector code, and pin number in the device load parameter library. This allows the device parameters of the same model, connector code, and pin number in the device load parameter library to be automatically retrieved.

[0074] To facilitate component selection, custom verification rules are stored in the logic prototype. These rules are not limited and are determined based on actual conditions. After storing the verification rules in the logic prototype, the verification rule library can be continuously enriched and improved, allowing for convenient direct retrieval of verification rule configurations later. Each verification rule includes configuration verification items, configuration table fields, operations, and configuration verification expressions. Configuration verification items include the circuit's rated voltage, minimum current, and maximum current; configuration table fields are parameter items from the component library (including relay coils). Operations in the verification rules include numerical values ​​(0-9), numerical operations (addition, subtraction, multiplication, division), comparison operations (greater than, less than, equal to, greater than or equal to, less than or equal to), logical operations (AND, OR, NOT), and other symbols (decimal point, parentheses), used to configure verification expressions. Circuit parameters and component library parameters are called, and verification rule expressions are formed using the operators in the verification rules for verification. In practice, different types of verification rules can be constructed based on the configuration verification items, configuration table fields, operations, and configuration verification expressions in the verification rules, and multiple verification rules can be configured simultaneously for verification. For example, the verification rules generated for a relay can be as follows: Verification Rule 1, which includes the verification item: minimum allowable current verification; expression: %1 > %2; Verification Rule 2, which includes the verification item: rated current verification; expression: %1 < %2. Here, %1 represents the maximum current, and %2 represents the rated current of the relay. Figure 2 This is a schematic diagram of a verification rule configuration provided in an embodiment of the present invention, as shown below. Figure 2 As shown, in the verification rules, the verification rules can be configured by selecting verification object A, selecting participating verification object B, and logical operation relationships (addition, subtraction, multiplication, division, greater than, equal to, less than, greater than or equal to, less than or equal to). The configured verification rules can be A≥B, or A<B, or A=B+2.

[0075] Run the component selection verification simulation program to automatically verify the components to be verified one by one. Using verification rule expressions, calculate and determine whether the component selection matches the requirements, and record the verification results. Based on the component selection verification results, generate a verification report, summarize various component selection data, and list the reasons for failing the component selection verification. For components that fail the verification, automatically compare parameters and recommend suitable component models.

[0076] The component determination method for a logic prototype provided in this invention includes: acquiring the device load and the component to be verified in the logic prototype; matching the component to be verified with standard characteristic parameters and matching the device load with device load characteristic parameters; after detecting a match, acquiring the loop parameters of the component to be verified in the current loop of the logic prototype; wherein the loop parameters are determined based on the current characteristics of the device load and the device load characteristic parameters matched to the device load; and determining the selection of the component to be verified according to the verification rules between the standard characteristic parameters and the loop parameters of the component to be verified pre-stored in the logic prototype. Compared with the previous method of manually selecting components, the method provided in this invention pre-stores standard characteristic parameters and device load characteristic parameters in the logic prototype, enabling the matching of parameters between components and device load to be verified within the logic prototype. After obtaining the loop parameters, since the logic prototype has pre-stored the verification rules between the standard characteristic parameters of the components to be verified and the loop parameters, the logic prototype can directly and automatically complete the verification of the component selection according to the verification rules, which greatly improves the efficiency of component selection. Moreover, compared with the manual selection method, the method provided by this invention is not easily affected by human factors, which greatly improves the accuracy of component selection.

[0077] After matching component parameters and device load parameters, there may be unmatched components and device loads. Therefore, in some embodiments, the completeness of parameter matching is verified. Specifically, before obtaining the loop parameters of the component to be verified in the current loop of the logic prototype, the following steps are also included:

[0078] If, within a preset time period, no component to be verified that does not match the standard characteristic parameters or no device load that does not match the device load characteristic parameters is detected, the process proceeds to the step of obtaining the loop parameters of the component to be verified in the current loop of the logic prototype.

[0079] From the moment the standard characteristic parameters of the component to be verified are detected to match, or from the moment the device load is detected to match the device load characteristic parameters, if a component to be verified that does not match the standard characteristic parameters or a device load that does not match the device load characteristic parameters is detected within a preset time period, then it is determined whether there are details of components to be verified that do not match the standard characteristic parameters in the component parameter library of the logic prototype, or whether there are details of device loads that do not match the device load characteristic parameters in the device load parameter library of the logic prototype.

[0080] If not, add details of components to be verified that do not match standard characteristic parameters to the component parameter library, or add details of device loads that do not match device load characteristic parameters to the device load parameter library; and proceed to the steps of matching the components to be verified with standard characteristic parameters and matching the device loads with device load characteristic parameters.

[0081] If so, re-enter the steps of matching the components to be verified with standard characteristic parameters and matching the device load with device load characteristic parameters.

[0082] Check for components or devices with mismatched characteristic parameters. If any are found, supplement the corresponding component details, device details, component parameter library, or device load parameter library. Output the integrity check results and provide prompts for components or devices that fail the integrity check.

[0083] Figure 3 This is a flowchart illustrating an automatic component selection verification method based on a logic prototype, provided as an embodiment of the present invention. Figure 3 As shown, the method includes:

[0084] S14: Create a logic prototype and import the component details and equipment details into the logic prototype;

[0085] S15: Automatically match component characteristic parameters and equipment load characteristic parameters in the logic prototype based on the component parameter library (including component characteristic parameters) and the equipment load parameter library (including equipment load characteristic parameters);

[0086] S16: Determine if the parameter integrity check passes; if yes, proceed to step S17; if no, proceed to step S18.

[0087] S17: Obtain components or devices in the logic prototype that do not match the characteristic parameters; and return to step S14;

[0088] S18: Run the simulation and record the simulation parameter values ​​of each component in each scenario;

[0089] S19: Determine the rationality of component parameters according to the verification rules;

[0090] S20: Output a verification report and recommended options for those that fail.

[0091] It should be noted that validation rules can be configured from the validation rule base, or the validation rule base can be updated after the validation rules are determined.

[0092] The loop parameters include the voltage values ​​of each contact, the minimum current value among all operating conditions, and the maximum current value among all operating conditions; obtaining the loop parameters of the component to be verified in the current loop of the logic prototype includes:

[0093] Set the rated current attribute of the pins for the device load;

[0094] Starting from the simulation of the current loop, obtain the pins whose pin states have changed among all the pins of the device load;

[0095] If a pin whose pin status has changed is detected to have a rated current attribute, then update the current value of the direct connection to the pin whose pin status has changed.

[0096] After the simulation is completed, obtain the voltage value of each contact, the minimum current value among the current values ​​corresponding to all operating conditions, and the maximum current value among the current values ​​corresponding to all operating conditions.

[0097] Alternatively, starting from the simulation of the current circuit, if a contact is detected to be open, the current value of the direct connection line where the pin on the energized side is located is updated; and the process proceeds to the steps of obtaining the voltage value of each contact, the minimum current value among the current values ​​corresponding to all operating conditions, and the maximum current value among the current values ​​corresponding to all operating conditions after the simulation is detected to be over.

[0098] Specifically, updating the current value of the directly connected line includes:

[0099] Obtain the current value and information of each power pin in the direct connection line;

[0100] If the power pin is a contact pin, obtain the current value of the contact pin;

[0101] The current value of the contact pin is updated from the current value to either the minimum current value or the maximum current value among all operating conditions, based on the relationship between the current value and the minimum current value or the maximum current value among all operating conditions, in order to update the current value of the directly connected line.

[0102] After updating the current value of the directly connected line, it also includes: obtaining the update time of the current value;

[0103] After detecting the end of the simulation and obtaining the voltage value of each contact, the minimum current value among the current values ​​corresponding to all operating conditions, and the maximum current value among the current values ​​corresponding to all operating conditions, the following is also included:

[0104] Store the voltage value of each contact, the minimum current value among all operating conditions, the maximum current value among all operating conditions, and the update time of the current value.

[0105] It should be noted that circuit operating conditions refer to the scenario after the switch is closed or open. A direct connection refers to a circuit between pins that are directly connected by a wire. A power pin refers to the pin that receives power from an external source for this direct connection, and there may be multiple power pins. Figure 4 This is a schematic diagram of a direct connection line provided in an embodiment of the present invention. Figure 4 In the diagram, the pins closest to 110V are power supply pins, the pins with two pins labeled 1 are non-power supply pins, the pins with two pins labeled 2 are power supply pins, and the pin A1 is a non-power supply pin. Figure 5 A flowchart of a method for obtaining loop parameters provided in an embodiment of the present invention is shown below. Figure 5 As shown, the method includes:

[0106] S21: Set the rated current attribute of the load pin;

[0107] S22: Update the direct-connection current value based on circuit simulation;

[0108] S23: Determine whether the simulation has ended; if yes, proceed to step S24; if no, return to step S22.

[0109] S24: Stores the simulated current data for each contact.

[0110] Specifically, in step S21, the rated current attribute of the load pin can be directly filled in or read from the component parameter library by the device model;

[0111] In step S22, circuit simulation is performed first to determine whether the pin is energized. If so, the rated current value is determined to be non-zero. If so, the direct-connection line current value is updated.

[0112] Alternatively, after the circuit simulation begins, determine whether the contact is open. If so, set the current value of the contact to 0 and update the current value of the directly connected line.

[0113] Figure 6 A flowchart of a method for updating a directly connected line provided in an embodiment of the present invention is shown below. Figure 6 As shown, the method includes:

[0114] S25: Calculate the current value of the power supply pin;

[0115] S26: Determine if the power pin is for a power supply device or a black box device; if so, end.

[0116] S27: Determine if the power pin is a contact pin; if so, proceed to step S28.

[0117] S28: Update contact current value;

[0118] S29: Obtain the pin on the other side of the contact and return to step S25.

[0119] In step S25, to calculate the current value of the power pins, the non-power pins are iterated through, and the current values ​​of each pin (for contact pins, the current value of the contact) are accumulated, then divided by the number of power pins to obtain the current value of each power pin. For example, for... Figure 4 For power pin 2, assuming the current value at the non-power pin is A, the current values ​​corresponding to the two power pins 2 are 2 / A respectively.

[0120] In step S28, the specific method for updating the contact current value is to record the current value and compare it with the minimum and maximum current values. If it is smaller than the minimum current value or larger than the maximum current value, then update it accordingly and record the update time.

[0121] The process of collecting and calculating the rated voltage, minimum current, and maximum current of the circuit containing the components is as follows:

[0122] (1) When drawing the circuit, the rated current attribute of the pins of the load device needs to be set. It can be filled in directly or read from the component library by the device model.

[0123] (2) During circuit simulation, the current value is calculated in real time:

[0124] ①When the status of a device pin changes, if the pin has a current attribute, update the current value of the directly connected line;

[0125] ②When the contact is open, the current value is 0, and the current value of the direct-connected line of the pin on the energized side is updated;

[0126] ③ Update the current value of the direct connection line and calculate the current value of the power supply pin;

[0127] Iterate through the non-power pins, sum the current values ​​of each pin (for contact pins, sum the current values ​​of the contacts), and then divide by the number of power pins to obtain the current value of each power pin.

[0128] Update the current values ​​for each power pin;

[0129] ④ Update the power pin current value. If the pin is a contact pin, update the contact current value and update the direct connection current value of the pin on the other side of the contact. If the pin is a black box or power supply device, notify the corresponding device.

[0130] ⑤ Update the contact current value, record the current value, and compare it with the minimum and maximum current values. If it is smaller than the minimum current value or larger than the maximum current value, update accordingly and record the update time.

[0131] (3) After the simulation is completed, store the voltage value, minimum current value (non-zero), maximum current value and corresponding time of each contact.

[0132] The component determination method for a logic prototype provided in this invention includes: acquiring the device load and the component to be verified in the logic prototype; matching the component to be verified with standard characteristic parameters and matching the device load with device load characteristic parameters; after detecting a match, acquiring the loop parameters of the component to be verified in the current loop of the logic prototype; wherein the loop parameters are determined based on the current characteristics of the device load and the device load characteristic parameters matched to the device load; and determining the selection of the component to be verified according to the verification rules between the standard characteristic parameters and the loop parameters of the component to be verified pre-stored in the logic prototype. Compared with the previous method of manually selecting components, the method provided in this invention pre-stores standard characteristic parameters and device load characteristic parameters in the logic prototype, enabling the matching of parameters between components and device load to be verified within the logic prototype. After obtaining the loop parameters, since the logic prototype has pre-stored the verification rules between the standard characteristic parameters of the components to be verified and the loop parameters, the logic prototype can directly and automatically complete the verification of the component selection according to the verification rules, which greatly improves the efficiency of component selection. Moreover, compared with the manual selection method, the method provided by the present invention is not easily affected by human factors, which greatly improves the accuracy of component selection.

[0133] In the above embodiments, the method for determining the components of a logic prototype has been described in detail. This invention also provides embodiments of a device for determining the components of a logic prototype and a device for determining the components of a logic prototype.
