Description

Technical Field

[0001] This invention relates to the field of electronic technology, and in particular to a measurement and control method, device, and measuring equipment. Background Technology

[0002] Currently, hardware engineers in the electronics field typically use multimeters to measure parameters such as voltage, current, resistance, and capacitance, or benchtop digital multimeters in laboratory environments.

[0003] However, multimeters have a unique operational characteristic: users need to manually switch ranges and select test items during testing. For example, to measure voltage, one must manually switch to the voltage range; to measure current, one must switch to the current range and change the probe position. This can easily lead to abnormal test results due to incorrect probe placement or range selection, resulting in a poor user experience. Furthermore, very few multimeters currently can measure inductance. Summary of the Invention

[0090] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0091] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0092] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0093] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0094] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0095] like Figure 1 As shown, an embodiment of the present invention provides a measurement and control method, comprising:

[0096] Step 101: Obtain the data to be measured from the measurement port.

[0097] In this step, the electrical parameter values ​​of the data to be measured connected to the measurement port can be detected through the measurement port. The measurement port can be used to connect a probe to detect the data to be measured (i.e., the signal to be measured).

[0098] Step 102: Identify the data to be tested and determine the type of electrical parameters of the data to be tested;

[0099] Step 103: Based on the electrical parameter type of the data to be tested, control the measurement port to connect with the measurement module corresponding to the electrical parameter type, so that the measurement module can measure the electrical parameter value of the data to be tested.

[0100] In this embodiment, the test data is acquired through a measurement port, and the electrical parameter type of the test data is analyzed. This allows the circuit between the measurement port and the appropriate measurement module (i.e., the measurement module corresponding to the electrical parameter type) to be connected, enabling the measurement of the electrical parameter value of the test data.

[0101] In this way, only one pair of measurement ports is needed. The measured item (here, the measured item can provide the data to be measured) is connected to this port. The measurement can be realized by automatically identifying the type of the data to be measured and conducting the corresponding circuit. There is no need to manually switch the range of the measuring instrument or change the probe position, thus avoiding abnormal test results caused by incorrect probe placement or range.

[0102] In one optional embodiment of the present invention, a single-port automatic electrical parameter measuring instrument (i.e., a measuring and control device) can be manufactured using the measurement and control method provided in the embodiments of the present invention, such as... Figure 2 As shown, this illustrates an optional internal module structure of the measuring instrument. The measurement port connects to the probe, which in turn connects to both ends of the measured item. The data to be measured is first processed by the "parameter pre-analysis module," which determines the type of parameter (i.e., the electrical parameter type), such as voltage, current, or resistance. Then, the measurement port is connected to the appropriate measurement module to measure the electrical parameter value of the measured data, which can then be displayed to the user.

[0103] The "parameter pre-analysis module" can analyze and identify the type of parameter (i.e., the specific electrical parameter type) of the parameter (i.e., the data to be measured) connected to the "measurement port". Based on the analysis and identification results, the "measurement port" is then connected to the corresponding measurement module.

[0104] Optionally, the electrical parameter types include at least one of the following: voltage, current, resistance, capacitance, and inductance.

[0105] As an optional embodiment of the present invention, the "parameter pre-analysis module" may include a "current analysis unit," a "capacitive resonance analysis unit," an "inductive resonance analysis unit," and a "control unit." The "current analysis unit" is used to detect whether current flows through the measurement port and whether there is overcurrent; the "capacitive resonance analysis unit" is used to detect whether capacitive resonance occurs when no current flows through the measurement port; the "inductive resonance analysis unit" is used to detect whether inductive resonance occurs when no capacitive resonance occurs; the "control unit" can be used to turn the "current analysis unit," "capacitive resonance analysis unit," "inductive resonance analysis unit," and "control unit" on or off. For example, turning on the "current analysis unit" indicates that the "control unit" connects the "current analysis unit" to the measurement port; the "control unit" can also be used to control the connection between the measurement port and the measurement module corresponding to the electrical parameter type. For example, the "control unit" can control... Figure 2 The measurement port shown is connected to the voltage measurement module.

[0106] Optionally, identifying the test data and determining the type of electrical parameters of the test data includes:

[0107] (i) Based on the data to be measured, determine whether there is current flowing through the measurement port;

[0108] (ii) When current flows through the measurement port, the electrical parameter type of the data to be measured is determined by detecting whether an overcurrent occurs at the measurement port.

[0109] As an optional embodiment of the present invention, the following can be adopted: Figure 3 The structure shown determines whether current flows through the measurement port and whether an overcurrent has occurred. Specifically, the "current analysis unit" includes a sampling resistor, a differential preamplifier, a post-amplifier for noise reduction, an overcurrent detector, and a control unit. The "current analysis unit" can determine whether current flows through the measurement port. If a voltage is input across the measurement port, an excessive current will be generated across the sampling resistor. In this case, the overcurrent detector activates (as shown in the "overcurrent detection + protection" section of the diagram). The output of the "current analysis unit" is connected to the "control unit." The result output by the "current analysis unit" is processed by the control unit's comprehensive logic to distinguish whether the parameter (i.e., the type of electrical parameter of the measured data) is voltage or current.

[0110] (iii) When no current flows through the measurement port, the electrical parameter type of the data to be measured is determined by detecting whether a capacitor resonance occurs.

[0111] Optionally, determining the type of electrical parameters of the data to be measured by detecting whether an overcurrent occurs at the measurement port includes:

[0112] In the event of an overcurrent, the electrical parameter type of the measured data is determined to be voltage;

[0113] Without overcurrent, the electrical parameter type of the measured data is determined to be current.

[0114] In this embodiment, it is possible to utilize, such as Figure 3 The circuit shown further detects whether an overcurrent occurs at the measurement port when current flows through it, in order to determine the type of electrical parameters of the data to be measured.

[0115] Optionally, determining the type of electrical parameters of the data under test by detecting whether capacitive resonance occurs includes:

[0116] In the case of capacitive resonance, the electrical parameter type of the data to be measured is determined to be capacitance;

[0117] In the absence of capacitive resonance, the type of electrical parameters of the data under test is determined by detecting whether inductive resonance occurs.

[0118] In this embodiment, when the measured parameter (i.e., the data to be measured) is not voltage or current, such as Figure 3 The "control unit" shown cannot receive a normal signal from the "current analysis unit". In this case, the "control unit" can connect its measurement port to the "capacitive resonance analysis unit". For details, please refer to [link to relevant documentation]. Figure 4 The circuit section of the "timing device" shown.

[0119] It should be noted that at this time, the input terminal of the "capacitive resonance analysis unit" is connected to the measurement port, and its output terminal is connected to the "control unit". When a capacitor is connected, the circuit of the "capacitive resonance analysis unit" will output a square wave signal, which the "control unit" can recognize. If the "capacitive resonance analysis unit" does not output a square wave signal, the next step is to determine the electrical parameter type of the data to be measured by detecting whether inductive resonance occurs.

[0120] Optionally, determining the type of electrical parameters of the data to be measured by detecting whether inductive resonance occurs includes:

[0121] When inductive resonance occurs, the electrical parameter type of the data to be measured is determined to be inductance;

[0122] Without inductive resonance, the electrical parameter type of the data to be measured is determined to be resistance.

[0123] In this embodiment, if the "capacitive resonance analysis unit" does not output a square wave signal, the "control unit" can connect the measurement port to the "inductive resonance analysis unit," as detailed in [reference needed]. Figure 5The "inductor resonance" circuit shown is used to input the data to be measured into the "inductor resonance analysis unit".

[0124] It should be noted that at this time, the input terminal of the "inductor resonance analysis unit" is connected to the measurement port, and its output terminal is connected to the "control unit". For example... Figure 5 As shown, the circuit of the "inductor resonance analysis unit" outputs a square wave signal when an inductor is connected, and the "control unit" can identify the square wave signal.

[0125] If the "inductor resonance analysis unit" outputs a square wave signal, the electrical parameter type of the data under test can be determined to be inductance; if the "inductor resonance analysis unit" does not output a square wave signal, the electrical parameter type of the data under test can be determined to be resistance.

[0126] Through the above steps, the "parameter pre-analysis module" can automatically identify the electrical parameters to be measured (i.e., determine the type of electrical parameters of the data to be measured). In this embodiment of the invention, basic electrical parameters such as voltage, current, resistance, capacitance, and inductance can be measured through a single port.

[0127] Optionally, controlling the connection between the measurement port and the measurement module corresponding to the electrical parameter type based on the electrical parameter type of the data to be measured includes one of the following:

[0128] When the electrical parameter type is voltage, control the measurement port to connect to the voltage measurement module;

[0129] When the electrical parameter type is current, control the connection of the measurement port to the current measurement module;

[0130] When the electrical parameter type is capacitance, the measurement port is connected to the capacitance measurement module.

[0131] When the electrical parameter type is resistance, the measurement port is connected to the resistance measurement module.

[0132] When the electrical parameter type is inductance, the measurement port is connected to the inductance measurement module.

[0133] In this embodiment, the voltage measurement module can be used to measure the specific value of the test data with the electrical parameter type of voltage; the current measurement module can be used to measure the specific value of the test data with the electrical parameter type of current; the capacitance measurement module can be used to measure the specific value of the test data with the electrical parameter type of capacitance; the resistance measurement module can be used to measure the specific value of the test data with the electrical parameter type of resistance; and the inductance measurement module can be used to measure the specific value of the test data with the electrical parameter type of inductance. Through these measurement modules, high-precision measurement can be achieved within a certain range.

[0134] Specifically, as an optional embodiment of the present invention, the voltage measurement module can be based on the voltage divider sampling measurement method, automatically switch between voltage ranges according to the measured voltage value, and use an ADC (Analog-to-Digital Converter) to acquire the output voltage value, ultimately achieving high-precision voltage measurement.

[0135] Current measurement module: can be adopted with Figure 3 Based on the circuit structure, the electronic components in the circuit are configured with optimal parameters, and the output voltage value is collected by ADC (which will change according to the change of current) to achieve accurate current measurement.

[0136] Resistance measurement module: Based on the voltage divider sampling measurement method, it automatically switches between ranges according to the measured resistance value, uses an ADC to collect the output voltage value, and finally achieves the highest accuracy resistance measurement.

[0137] Capacitance measurement module: can be used with Figure 4 Based on the basic circuit structure, the electronic components within the circuit are configured with optimal parameters. Different capacitor values ​​will change the frequency of the output square wave. The calculation formula can be expressed as follows:

[0138]

[0139] Where R1 and R2 represent adjustment resistors, C represents the capacitor under test, and f is the frequency of the output square wave.

[0140] Inductance measurement module: can be adopted with Figure 5 Based on the basic circuit structure, the electronic components within the circuit are configured with optimal parameters. Different capacitor values ​​will change the frequency of the output square wave. The calculation formula can be expressed as follows:

[0141]

[0142] Where C represents the adjustment capacitor, L represents the inductance under test, and f represents the frequency of the output square wave.

[0143] like Figure 6 As shown, the solutions provided in the embodiments of this application will be specifically illustrated below.

[0209] The transceiver 910 is used to receive and send data under the control of the processor 900.

[0210] Among them, Figure 9In this context, the bus architecture can include any number of interconnected buses and bridges, specifically linking various circuits of one or more processors represented by processor 900 and memory represented by memory 920 together. The bus architecture can also link various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. The bus interface provides an interface. Transceiver 910 can be multiple elements, including transmitters and receivers, providing a unit for communicating with various other devices over a transmission medium. For different user equipment, user interface 930 can also be an interface capable of connecting external or internal devices, including but not limited to keypads, displays, speakers, microphones, joysticks, etc.

To avoid repetition, further details are omitted here. The computer-readable storage medium may include read-only memory (ROM), random access memory (RAM), a magnetic disk, or an optical disk.

[0213] It should be further noted that the terminals described in this specification include, but are not limited to, smartphones, tablets, etc., and many of the functional components described are referred to as modules in order to emphasize the independence of their implementation.

[0214] In this embodiment of the invention, the module can be implemented in software so that it can be executed by various types of processors. For example, an identified executable code module may include one or more physical or logical blocks of computer instructions, which may be constructed as objects, procedures, or functions. Nevertheless, the executable code of the identified module does not need to be physically located together, but may include different instructions stored in different bits, which, when logically combined, constitute the module and achieve the module's intended purpose.

[0215] In practice, an executable code module can be a single instruction or many instructions, and can even be distributed across multiple different code segments, different programs, and across multiple memory devices. Similarly, operational data can be identified within the module and can be implemented in any suitable form and organized within any suitable type of data structure. This operational data can be collected as a single dataset or distributed across different locations (including different storage devices), and can exist, at least in part, solely as electronic signals within the system or network.

[0216] When a module can be implemented using software, considering the current level of hardware technology, modules that can be implemented in software can be implemented using hardware circuits by those skilled in the art to achieve the corresponding functions, without considering cost. These hardware circuits include conventional very-large-scale integrated circuits (VLSI) or gate arrays, as well as existing semiconductors such as logic chips and transistors, or other discrete components. Modules can also be implemented using programmable hardware devices, such as field-programmable gate arrays, programmable array logic, and programmable logic devices.
