Description

Multimeter measurement system with improved measurement convenience

According to the present invention, non-experts can also easily measure the measurement procedure by the type of measurement object, and also can easily understand the status of the measurement object failure or lifespan, and if there is a problem in the measurement object. The present invention relates to a multimeter-specific metrology system with improved metrology convenience that allows rapid follow-up actions.

As is well known, a multimeter is an electrical meter which combines various measurement functions such as electrical resistance of a conductor, voltage and current between two points, and is widely used in industrial fields.

However, conventional multimeters, especially digital multimeters, have a lead wire for contacting a target point to collect electrical signals, a range for converting and adjusting the collected electrical signals to a specified form, and an adjusted electrical signal for electrical measurement and output. Since a processor for analyzing and converting data into a data and a display for outputting the data as text or an image are integrated and manufactured, a conventional multimeter is a portable single device having a relatively large size.

Furthermore, since the conventional multimeter has a function of individually measuring various electrical characteristics such as voltage, current, resistance, power, and wave for various measurement targets, there are various methods of modifying and measuring modes according to electrical characteristics. The locations where the probe should be contacted also varied. Of course, those skilled in the art that use the conventional multimeter smoothly this task will not be difficult, but the majority of ordinary people are difficult to use the conventional multimeter because the majority of the ordinary people are outside the method of measurement by mode for the measurement object. There was this.

On the other hand, the general public who has a relatively low chance of using the multimeter does not realize the necessity, so it is rare to have a relatively large size multimeter at home. However, as the variety of household electrical appliances has increased and increased, the need for checking or checking the status of electrical appliances in an emergency has gradually increased. Accordingly, the public has also become aware of the need for a multimeter.

However, as described above, the conventional multimeter is a single device of a relatively large size, and despite the necessity described above, the general public has suffered without having a multimeter at home.

In order to solve such a problem, a technique for coupling a multimeter to a smartphone, which is a necessity that a worker and a general public (hereinafter, a user) always carry, has been proposed. This technology has only a lead wire, a range, and a processor that allows a multimeter connected to a smartphone to collect, measure, and convert the electrical signal to be measured, and the smartphone has a display function that simply outputs data transmitted from the multimeter. Only made. Therefore, the conventional multimeter can significantly lower the unit cost, and works in conjunction with a smartphone that is familiar to the user, thereby improving convenience than an independent conventional multimeter.

However, since the conventional multimeter technology merely performs the monitor function, the user who is connected to the smart phone has the inconvenience of directly operating the multimeter. For this purpose, the size of the conventional multimeter also needs to have a sufficient size. there was. Of course, this inconvenience leads to the user's avoidance of using the multimeter, so that the problems with the conventional multimeter have not been solved.

In addition, the conventional multimeter has a different measuring method of the measurement target, and the terminology and display are very unfamiliar to the general public.

Accordingly, the present invention has been invented to solve the above problems, regardless of the type of measurement object and the electrical characteristics to be measured can be easily measured by the general public, and can easily determine the state of the measurement object according to the measurement result, It is also an object of the present invention to solve the problem of providing a multimeter-specific measurement system with improved usability.

In order to achieve the above object, the present invention,

According to the present invention, regardless of the type of measurement object and the electrical characteristics to be measured, the general public can easily measure, and the state of the measurement object can be easily grasped according to the measurement result, and the usability is also improved. There is.

In addition, the range of the conventional multimeter performed the measurement only when the user directly selects the measurement contents for the electrical characteristics such as voltage, current, electrical form (AC / DC), disconnection, and resistance of the measurement object. Since the measurement contents of the measurement target are automatically recognized and displayed on the smartphone (for example, screen display example: AC220V, DC12V, DC1.43V, disconnected, connected, 35K ohms, etc.), the user simply touches the multimeter's lead to the measurement target. Also can check the desired measurement information on the smartphone, through which there is an effect that the general public can easily measure a variety of measurement targets without any difficulty.

In addition, since the user can easily grasp and replace the measurement target even in case of emergency such as a failure of the measurement target, there is an effect of quickly eliminating inconvenience caused by the failure of the measurement target.

It is a figure which showed implementation.

S10; Instrumentation Execution Steps

As is well known, applications installed on the smartphone 200 are executed based on the OS 220. The application generates an icon on the screen of the smartphone 200, and when the user clicks the icon, the corresponding application is executed and outputs the main page.

A method for inputting measurement target information may be presented in the main page menu, and the present embodiment may include a direct input method in which a user directly inputs measurement target information, and a user who does not know the measurement target information as an image. Illustrates a selection input method of selecting. However, the method for inputting the measurement target information is not limited thereto and may be variously modified.

On the other hand, when the user selects a menu on the main page, the program module 230 transmits the instruction data for the mode setting of the multimeter 100 to the multimeter 100 to generate the corresponding analysis data for each mode.

S20; Instrumentation Server Connection Stage

The program module 230 of the present embodiment automatically connects to the measurement server 300.

The program module 230 may not store various kinds of electrical article information due to the limitation of the storage capacity of the smartphone 200. Therefore, in order to accurately search for electrical article information matching the measurement object, a separate measurement server 300 is constructed, and the smartphones 200 and 200 'on which the multimeters 100 and 100' are installed measure the measurement server 300. To communicate with

The measurement server 300 may provide the guide data only to the member in order to provide the guide data for a member system or to provide a fee. At this time, the login to the measurement server 300 can be made automatically or manually, in the case of automatic program module 230 transmits the ID / PW of the user and the identification code of the smartphone to the measurement server 300 to log in and connect To complete. When the login connection is completed between the measurement server 300 and the smartphone 200, the measurement server 300 and the smartphone 200 may maintain bidirectional communication without separate control of the user.

S30; Enter specific information

The program module 230 requests specific information about the measurement target T as shown in FIG. 4, and the user checks the information of the measurement target T and inputs specific information in the corresponding column.

In FIG. 4A, the input field output by the program module 230 includes a 'measurement object type' input field and a 'model name' input field. The user directly inputs a 'measurement object type' input field and a 'model name'. Enter the measurement target information corresponding to one or more selected fields.

Subsequently, the program module 230 transmits the electrical article information to the measurement server 300 when the electrical article information is input.

For reference, the program module 230 of the present embodiment processes the measurement content of the measurement target T as output measurement information from the analysis data generated by processing the electrical signal received by the multimeter 100, and the user It generates the corresponding indication data according to the selected mode, and communicates with the measurement server 300 and stores the page form for the transmission of the measurement target information input by the user and the output of the received information. Therefore, the measurement target information input by the user in FIG. 4A is automatically transmitted to the measurement server 300.

The program module 230 may alternatively select an input page for directly inputting measurement target information to be guided by the user (FIG. 4A) and electrical article information related to the measurement target T. The listed selection page (Fig. 4 (b)) is output to the input / output module 240 of the smartphone 200. The selection page is described again below.

S40; Measurement target step

The measurement server 300 receives specific information from the smartphone 200 and transmits the specific information to the guide module 340, and the guide module 340 retrieves corresponding electric article information from the content DB 330 based on this.

As a result of searching for the electrical article information matching the measurement target T, the guide module 340 transmits the electrical article information to the smartphone 200, and the program module 230 of the smartphone 200 is shown in FIG. As shown in (a) of Fig. 4, the electrical article image as the search result is output.

The user confirms the image of the electrical article and finally determines the electrical article of the measurement target T to be measured by the user.

However, the measurement object information input by the user may be insufficient, and thus the measurement server 300 may not be able to retrieve the target electrical article information. In this case, the guide module 340 searches the content DB 330 for high electrical similarity information based on the measurement target information input by the user, and transmits the corresponding data to the smartphone 200.

The program module 230 of the smartphone 200 alternatively lists the electrical article information, which is the data, as a selection page as shown in FIG. 4 (b). In the present embodiment, since the electrical article information output on the selected page includes an image of the electrical article as a target, the user can easily select by comparing the image with the actual measurement target T to be measured.

By the alternative method described above, the user is finally determined as the electrical article of the measurement target T to be measured.

S50; Guide data loading step

The program module 230 transmits the determined electric product information to the measurement server 300, and the measurement server 300 retrieves the guide data for the electric product information from the content DB 330 to the smartphone 200. send.

The program module 230 loads the guide data received from the measurement server 300 and outputs the guide message through the input / output module 240 as shown in FIG. 5 or 6.

The guide message shown in FIG. 5 is a video (M) related to the measurement of the corresponding electrical article, and the user learns the contents related to the measurement of the electrical article while watching the video, and measures the measurement target (T) according to the learned procedure. You can proceed.

The guide message shown in FIG. 6 is an animation or graphic (G), and the user contacts the terminals indicating the probe 121 in the order of the guide message, and confirms the input of the electrical signal. Print out a message so that subsequent measurements can be made. In this embodiment, the guidance and measurement of the guide message are performed at the same time, but in addition, the guide data is loaded first to guide all the measurement procedures before the actual measurement of the measurement target T, and the user executes the guide data for the measurement procedure. After this completion, the measurement of the measurement target T may be made to proceed.

S60; Receiving Electric Signal

The pair of probes 121 formed at the ends of the lead wires 120 of the present embodiment respectively contact the terminal portions of the measurement target T in accordance with the guidance of the guidance message. If there is no energization at a specific point of the measurement target (T), the probe 121 of the lead wire 120 does not receive an electric signal and does not transmit the electric signal to the range module 130. However, if the specific point is energized, the probe 121 of the lead wire 120 receives the electric signal, and the received electric signal is transmitted to the range module 130.

For reference, if the measurement target (T) is currently connected to a power source (hereinafter referred to as a 'socket') such as a normal socket (not shown) or other capacitor, and is being driven, the current is applied to the measurement target (T) by a separate external voltage. Since there is, and receives the electrical signal through the probe 121 in contact with the measurement target (T). However, if the measurement target (T) is separated from the socket or if there is a problem with the socket itself or a problem with both the socket and the measurement target, the probe 121 in contact with the measurement target (T) does not receive an electrical signal. If the measurement target (T) receives a voltage of a predetermined size, it may be confirmed that the measurement target (T) is broken or the probe 121 is in contact with an incorrect terminal position.

Subsequently, when the electric signal is not received, the multimeter 100 according to the present embodiment may receive confirmation from the user or apply a current to the measurement target T arbitrarily in order to confirm whether the measurement target T or the socket has failed. Can be. In more detail in terms of configuration, the voltage module 160 inherent in the multimeter 100 generates a voltage having a predetermined magnitude under the control of the CPU 142 and applies the measurement target T to the measurement. It is checked whether an electrical signal is received by the probe 121 in contact with the object T.

When the current of the voltage module 160 is applied, the normal measurement target T transmits a corresponding electric signal to the probe 121 through operation. After that, if the probe 121 receives a normal electrical signal, the multimeter 100 performs measurement on the measurement target T based on this. However, the electrical signal is not received by the probe 121 even after the current of the voltage module 160 is applied, and it may be estimated that there is a problem in the measurement target T itself or a problem in both the measurement target T and the socket. .

On the other hand, the voltage module 160 configured in the multimeter 100 may be its own battery, but preferably receives a current from the smartphone 200 and processes it to be applied to the measurement target (T).

S70; Electrical signal adjustment step

The range module 130 that receives the electrical signal adjusts the electrical signal to an allowable condition for the process module 140 to process. To this end, the range module 130 includes a transformer 131 for converting the voltage of the electrical signal to the allowable condition that the process module 140 can process, and a phase upward shift for converting the phase of the received electrical signal into a sine wave having only a + component. Section 132. While the voltage range that the process module 140 can receive and analyze is limited, the multimeter 100 can receive electrical signals of various voltages. Therefore, the range module 130 includes a transformer 131 for transforming electrical signals of various voltages received from the outside into the analysis voltage range of the process module 140. The transformer 132 of the present embodiment may be limited only to the decompression function because the measurement may be performed mainly on a high voltage target of AC110V or AC220V. It can also be equipped. As a result, the transformer 131 may selectively perform the decompression or boosting function under the control of the CPU 142 according to the electric signal.

On the other hand, since the multimeter 100 of the present embodiment can measure not only the direct current but also the measurement target T for the alternating current, when the electrical signal is the direct current, the phase upward part 132 maintains the electrical signal. When the electrical signal is alternating current, the phase up unit 132 converts the electrical signal into a sine wave. For example, when the electric signal of AC220V is input, it is reduced by 1/100 through the transformer 131 and becomes AC2.2V. At this time, AC is changed 60 times from + 2.2V to -2.2V. Change to a sinusoidal wave with only the + component that varies from 0.1V to + 4.5V.

As a result, the range module 130 rectifies and transforms the electrical signal received from the measurement target T to the process module 140.

S80; Electrical signal processing stage

The process module 140 analyzes the electrical signal received from the range module 130 and outputs analysis data regarding electrical characteristics of the electrical signal such as voltage, current, resistance, and wave of the electrical signal. In addition, the instruction data received from the smartphone 200 is processed to set the type, measurement conditions, and the like of the electrical signal characteristics that the multimeter 100 is to measure. To this end, the process module 140 is an A / D conversion unit 141 for converting the electrical signal received from the range module 130 into a digital format, and analyzes the electrical signal in a digital format to output analysis data and the instruction data. It includes a CPU 142 for receiving and processing.

Since the electrical signal adjusted by the range module 130 is an analog format, the process module 140 for processing a digital format signal cannot process the electrical signal received from the range module 130. Therefore, the A / D converter 141 of the process module 140 converts the electric signal adjusted by the range module 130 into a digital format.

The CPU 142 analyzes an electrical signal in a digital format according to a set process, outputs analysis data relating to electrical characteristics of the electrical signal, and processes the indication data received from the smartphone 200 to fit the indication data. Set the processing environment to output In addition, even if a separate instruction data is not received from the smartphone 200, if there is no voltage in the process of analyzing the electrical signal, the voltage module 160 may be controlled to receive a corresponding electric signal by applying a current of a required voltage. have.

Therefore, when the indication data is a signal for confirming only the current of the measurement target T, the CPU 142 analyzes and outputs only the current from the electric signal in the digital format. In addition, in the case of a signal for checking only voltage, the CPU 142 analyzes and outputs only a voltage from an electric signal in a digital format. In addition, the CPU 142 may output only the analysis data analyzing various electrical characteristics irrespective of the instruction data and transmit all of them to the smartphone 200, or after analyzing and outputting all electrical characteristics, corresponding analysis corresponding to the instruction data. Only data may be selected and sent to the smartphone 200. In addition, the indication data may be a signal for controlling ON / OFF of the multimeter 100.

For reference, the analysis data generated by the CPU 142 may be electrical characteristics such as voltage, current, resistance, power, and wave of the measurement target T, and at least one of voltage, current, resistance, power, and wave. May be derived by calculating other electrical signals, and the derived data is generated as analysis data.

S90; Telecommunication stage

The process module 140 of the multimeter 100 transmits the analysis data to the smartphone 200. In addition, the instruction data is received from the smartphone 200. Such information communication is performed through the

connection modules

150 and 210 of the multimeter 100 and the smartphone 200.

For reference, the connection module 210 of the smartphone 200 includes a port to which the code 111 of the multimeter 100 is mechanically engaged, and a wiring structure to the OS 220 and the program module 230. . Since the connection module 210 of the smartphone 200 is already known technology, a detailed description thereof will be omitted.

S100; Information processing steps

The analysis data received from the multimeter 100 is processed by the program module 230 and output to the input / output module 240 of the smartphone 200 in a designated format as shown in FIG. 7 or 8.

As described above, the program module 230 is an application programmed to be executed based on the OS 220 of the smartphone 200, and outputs a page of a specified format to the input / output module 240 of the smartphone 200. The measurement content, which is an electrical characteristic of the measurement target T, is posted on the page at the corresponding position as measurement information or converted into measurement information in the form of numbers, graphs, texts, and the like.

Furthermore, the measurement system of the present embodiment can grasp the state of the measurement target T and guide the user.

In more detail, the program module 230 checks the measurement information and checks electrical characteristics such as current, voltage, resistance, power, and wave, which are measurement contents of the measurement target T.
