Description

  The present invention relates to a characteristic value measuring system, a characteristic value measuring apparatus, and a management apparatus, and in particular, a characteristic that makes it possible to reliably and reliably measure various electric characteristic values of a large number of electric workpieces installed in a wide range. The present invention relates to a value measurement system, a characteristic value measurement device, and a management device.

  Electric utilities that are installed and managed by electric power companies include power meters, breakers, etc., in the installation facilities for consumers, such as transformers, switches, lightning arresters, and junction boxes installed on distribution poles. There are various devices, and whether the ground resistance or insulation resistance (hereinafter sometimes referred to as “electrical characteristic value” or simply “characteristic value”) is maintained at a predetermined value for the outer box of these devices. It is stipulated by laws and regulations to measure and manage regularly.

  These various electric works may reach thousands of locations within the sales office of an electric power company in charge of management, and such a large number of various electric works are not only in urban areas but also in vehicles. It is installed so as to be scattered in mountainous areas that cannot be reached. A staff member who performs measurement of characteristic values, for example, ground resistance value, using these electric workpieces as a measurement target, carries a ground measurement meter and visits the installation location of the electric workpiece that has been designated as the measurement target in advance. The ground resistance value of the target workpiece is measured by a measuring meter, and the measurement result is recorded on a predetermined measurement slip. In recent years, a mobile terminal such as a PDA (Personal Digital Assistant) is carried along with a measuring instrument such as a grounding meter, and a measurement result obtained by the measuring instrument is input to the mobile terminal as digital data and recorded. ing.

  Furthermore, a system that supports the identification of a measurement target using a GPS (Global Positioning System) has been proposed. For example, Patent Document 1 collates position data represented by latitude and longitude of a group of equipment collected and accumulated in advance with position data of a work point represented by latitude and longitude measured at the work site. An equipment specifying system having a configuration for specifying equipment is disclosed.

  Patent Document 2 discloses an on-site measurement system used at a construction site or a topographic survey site, which has a positioning function using GPS.

  In this way, efforts are being made to save labor for measurement work by staff, but there is no change in the point that it is necessary to perform measurement work by visiting electric works installed extensively from urban areas to mountain areas. There are still the following problems.

  Before going out for a patrol for measurement work, a staff member takes in a list of electric works to be patroled on that day from a computer terminal of a sales office to which the staff belongs. Each electric work is normally specified by an identification code (for example, “1-1” etc.) defined for each electric power company. The clerk will carry out the measurement and recording work independently according to this traveling list. At this time, the electrical work to be measured is mistakenly specified, for example, the original “1-1” distribution pole is recorded. An error may occur in which the measured value to be recorded is recorded corresponding to “No. 1-2”. Alternatively, even if the electrical workpiece to be measured is appropriately specified, a numerical input error may occur when a measured value by a measuring instrument such as a grounding meter is input to a PDA or the like.

  In addition, as described above, the electric workpiece to be measured may be located in a mountain that cannot be reached by a vehicle, so even though the clerk is prepared and actually does not measure it locally. However, there is a problem that it is not possible to create a so-called data by recording a numerical value on a PDA or the like. In other words, no matter how hard the staff records and reports the measured values, it is not possible to prove whether it is the result of actually going to the site and conducting the measurement work. Become.

The measurement apparatus 100 includes, as main hardware elements, a central processing unit 101 (for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), hereinafter referred to as “CPU” for simplicity), and a main memory 102 (for example, a RAM ( Random Access Memory (ROM), ROM (Read Only Memory)), auxiliary storage device 103 (for example, hard disk drive (Hard Disk Drive, HDD), semiconductor storage device (Solid State Drive, SSD), and input unit 104 (for receiving user operation input) For example, a pointing device such as a keyboard, a mouse, and a touch pad), an output unit 105 (for example, a liquid crystal display element), a communication interface 106 (for example, a NIC (Network Interface Card)) for realizing communication with other devices, a GPS receiving unit 110 and a ground resistance measurement unit 120.

  The measurement apparatus 100 includes a measurement processing unit 130, an encryption unit 140, and a measurement data storage unit 150 as main software elements.

  The CPU 101, the main memory 102, the auxiliary storage device 103, the input unit 104, the output unit 105, and the communication interface 106 are a group of hardware that realizes the function of the measuring apparatus 100 as a computer. An operating system (OS) operating on the CPU 101 is not particularly limited to a specific system. For example, OSs such as Windows CE (registered trademark) and Linux-based Android (registered trademark), which are preferably used for portable terminals such as PDAs, can be mentioned.

  The GPS receiving unit 110 receives a signal including GPS data transmitted from the GPS satellite AS of FIG. 1 via the antenna ANT, acquires latitude data and longitude data from the GPS data, and a measurement processing unit described later The process of handing over to 130 is executed. As will be described later, in addition to latitude data and longitude data, altitude data can also be acquired and used. FIG. 2 illustrates a configuration in which the antenna ANT is provided outside the GPS receiving unit 110. As the GPS receiving unit 110, for example, the antenna ANT converts an analog signal from the GPS satellite AS into a digital signal. Various functions that are stored in a single module integrated with a baseband block that has a function of extracting data such as latitude data and longitude data by decoding GPS data received from the RF block and the RF block having functions, etc. A GPS receiver can be used.

  The ground resistance measurement unit 120 (characteristic value measurement unit) measures a resistance value between two different points connected in series with a ground electrode to be measured for ground resistance, such as an outer box of a transformer, It is a measuring instrument that can calculate the grounding resistance of the grounding electrode based on them. That is, the ground resistance measuring unit 120 has the same configuration as a conventional ground measuring instrument including a probe PB for measuring a resistance value as hardware. In the measurement apparatus 100 of the present embodiment, the ground resistance value measured by the ground resistance measurement unit 120 is delivered to the measurement processing unit 130 described later for post-processing. In the present embodiment, the ground resistance measurement unit 120 is exemplified as a structure provided integrally with a part equivalent to a mobile terminal such as a PDA such as the CPU 101. However, the ground resistance measurement unit 120 is The ground measuring device may be provided separately from the PDA equivalent part, and a signal interface may be prepared so that the measurement value output signal of the ground measuring device can be input to the measurement processing unit 130.

  The measurement processing unit 130 is a functional block realized by reading a program stored in the auxiliary storage device 103 or the like into the main memory 102 and executing it by the CPU 101. The measurement processing unit 130 mainly associates the latitude data and the longitude data of the measurement target workpiece acquired from the GPS reception unit 110 with the ground resistance value of the measurement target measured by the ground resistance measurement unit 120 to be described later. Processing to be stored in the measurement data storage unit 150 is executed.

  The encryption unit 140 performs a process of converting the ground resistance measurement value data stored in the measurement data storage unit 150 by the measurement processing unit 130 into encrypted data by a predetermined encryption method. By encrypting the ground resistance measurement value data before storing it in the measurement data storage unit 150, the clerk reads out the ground resistance measurement value data stored in the measurement data storage unit 150 and makes subsequent changes. Can not be. This not only prevents the staff from intentionally changing the measured value data, but also prevents the staff from inadvertently changing the measurement data unintentionally.

  Similar to the measurement processing unit 130, the encryption unit 140 is a functional block realized by reading a program stored in the auxiliary storage device 103 or the like into the main memory 102 and executing it by the CPU 101. As an encryption algorithm, an appropriate method can be adopted in consideration of encryption strength and convenience, including DES (Data Encryption Standard) and AES (Advanced Encryption Standard). It should be noted that the encryption processing of the ground resistance measurement value data by the encryption unit 140 is not essential for the present invention, and can be selectively incorporated as appropriate.

<< Configuration of Management Computer 200 >>
Next, the configuration of the management computer 200 in this embodiment will be described. FIG. 3 shows an example of the hardware and software configuration of the management computer 200 in this embodiment.

  The management computer 200 as hardware is a server computer that can be communicably connected to the measurement apparatus 100 via the communication network NW shown in FIG. 1, and includes a CPU 201, a main memory 202, an auxiliary storage device 203, an input unit 204, and an output. A unit 205 and a communication interface 206. Since the configuration of each of these hardware units is almost the same as that of the measurement apparatus 100, detailed description thereof is omitted. However, since the measurement apparatus 100 that is a portable information terminal is not restricted by the shape and size, power consumption, and the like, the degree of freedom in selecting the specific configuration of each unit is increased. Similarly, in terms of software, for example, normal Windows (registered trademark), UNIX-based Linux (registered trademark), or the like can be employed as the OS running on the CPU 201.

  The measurement data receiving unit 210 measures the ground resistance value of each electric workpiece measured by the measurement apparatus 100 and stored in the measurement data storage unit 150 via the communication network NW, that is, the position information where the measurement is performed, that is, GPS. It is received from the measuring apparatus 100 together with latitude data and longitude data acquired from the receiving unit 110. The received measurement data is delivered to the measurement data processing unit 220 or the decoding unit 230 described later.

  The measurement data processing unit 220 is a process for mainly collating the measurement data received from the measurement data receiving unit 210 with the position information of the electric workpiece that is each measurement object stored in the measurement object information storage unit 240 described later. Etc. Data processing by the measurement data processing unit 220 will be described later with a processing flow as an example.

  The decryption unit 230 is a functional block having a function of decrypting encrypted data received from the measurement device 100 when the encryption unit 140 is mounted on the measurement device 100.

The measurement target information storage unit 240 associates the identification information (ID, electric workpiece identifier) of the electric workpiece that is the measurement target of the grounding resistance value with its position information (latitude data and longitude data, installation position information) in advance. For example, each function of the measurement data receiving unit 210, the measurement data processing unit 220, and the decoding unit 230 stores a corresponding program as an auxiliary storage. This is realized by storing in the apparatus 203 and reading out to the main memory 202 by the CPU 201 and executing it.

<< Measurement data table 400 >>
Next, the measurement data table 400 held in the measurement data storage unit 150 of the measurement apparatus 100 will be described. FIG. 4 shows an example of the configuration of the measurement data table 400.

  The measurement data table 400 includes, for each electric workpiece that is a measurement object of the ground resistance value, information for specifying the measurement object, and a ground resistance measurement value and position information (measurement position information) for each measurement object. And time information. Specifically, in the case of this embodiment, as illustrated in FIG. 4, the measurement data table 400 includes a measurement object ID 401 (electric workpiece identifier), a ground resistance measurement value 402, position information 403 (measurement position). Information) latitude data 403a and longitude data 403b, and time information 404 are recorded.

  The measurement object ID 401 is assigned to identify electric works such as pole transformers and switches, which are to be measured for grounding resistance, from each other by a facility where the measurement object is installed, for example, a distribution pole. It is an identification code of the measuring object. In the example of FIG. 4, for example, an ID such as “1-1” is assigned, but an electric power company or the like that operates the system 1 may attach an appropriate code.

  The ground resistance measurement value 402 records the ground resistance measurement value received from the measuring apparatus 100 in association with the measurement object ID 401. In the measurement apparatus 100, when the measurement value is encrypted by the encryption unit 150, the received encrypted data is decrypted by the decryption unit 230 and then recorded in the measurement data table 400 as the ground resistance measurement value 402. Is done.

  The position information 403 includes latitude data 403a and longitude data 403b. The latitude data 403a and longitude data 403b are obtained by the measurement processing unit 130 from the GPS receiving unit 110 of the measurement apparatus 100. In the example of FIG. 4, both latitude data 403a and longitude data 403b are recorded in accordance with a format (for example, NMEA0183) defined by NMEA (National Marine Electronics Association). In this embodiment, since the area where the measuring apparatus 100 is used is limited, the identification code indicating the north latitude and the east longitude is not attached with respect to the latitude, but of course, these identification codes may be included. .

  The time information 404 is obtained by acquiring the time when the measurement processing unit 130 of the measuring apparatus 100 records the ground resistance measurement value in the measurement data table 400 from the system clock of the CPU 101 and recording it.

  With the above measurement data table 400, when the measuring apparatus 100 measures the ground resistance value for a certain measurement object (electric work), the position information and the time information of the point where the measurement is performed are automatically obtained. Recorded in the measuring device 100.

<< Measurement target information table 500 >>
Next, the measurement target information table 500 held in the measurement target information storage unit 240 of the management computer 200 will be described. FIG. 5 shows an example of the configuration of the measurement target information table 500.

  The measurement object information table 500 includes, for each electric workpiece that is a measurement object of the grounding resistance value, information for specifying the measurement object and position information (latitude measured and recorded in advance for each measurement object). Data and longitude data), and the ground resistance value measured most recently for each measurement object is recorded. Specifically, in this embodiment, as illustrated in FIG. 5, the measurement target information table 500 includes a measurement target ID 501, a ground resistance measurement value 502, and latitude data 503 a and longitude as position information 503. Data 503b is recorded.

  The measurement object ID 501 (electric workpiece identifier) is the same as the measurement object ID 401 in the measurement data table 400 of FIG. The ground resistance measurement value 502 is the same as the ground resistance measurement value 402 in the measurement data table 400 of FIG. 4, but what is recorded is the measurement value (past measurement value) acquired and recorded most recently from the measurement apparatus 100. ).

  The position information 503 (installation position information) includes the same contents as the position information 403 in the measurement data table 400 of FIG. 4, but the latitude data 503a and longitude data 503b of the position information 503 are set in advance for each measurement object. The difference is that it was measured and recorded at the position. The latitude data 503a and the longitude data 503b recorded in the position information 503 of the measurement target information table 500 are associated with the latitude data 403a and the longitude data 403b acquired when the ground resistance value is measured by the measuring apparatus 100. A reference value for determining whether the measured object ID 401 is an appropriate numerical value is provided. That is, as will be described later, the position information 403 recorded in the measurement apparatus 100 for a certain measurement object is compared with the position information 503 as a reference value held in advance in the management computer 200 to thereby obtain the measurement object. It is possible to determine whether or not the grounding resistance value for is measured without error.

<< Process flow of this system >>
Next, the content of the process of the ground resistance measurement system 1 according to the present embodiment will be described. FIG. 6 shows an example of a processing flow executed in the system 1. This processing flow includes a part executed by the measuring apparatus 100 and a part executed by the management computer 200, both of which are shown in FIG.

  First, the measurement processing unit 130 of the measurement apparatus 100 communicates with the measurement data processing unit 220 of the management computer 200 via the communication interface 106 and the communication network NW, and the measurement data processing unit 220 transmits an electric workpiece to be measured. A list is acquired (S601). Although omitted in FIG. 3, for example, an electric power company or the like has prepared in advance a schedule for daily inspection of various facilities and equipment. For example, a list of electrical workpieces to be measured is acquired every day, and the ground resistance value is measured based on the list. Note that the measurement target list is acquired by specifying, for example, an ID assigned to a staff member who performs measurement or the measurement device 100 used for measurement, as is commonly performed in various industrial fields. It becomes. In addition, the measurement object description order in the measurement object list is usually sorted in such an order that the measurement object can be circulated most efficiently.

  The staff member who has acquired the measurement object list carries the measurement device 100 and starts the ground resistance measurement work for the electric workpiece to be measured. The clerk performs the ground resistance measurement for the electric workpiece, which is the first object to be measured, using the measuring apparatus 100 (S602). The ground resistance measurement unit 120 passes the ground resistance value measurement data measured for the measurement object to the encryption unit 140, and the encryption unit 140 encrypts the received measurement value data using a predetermined encryption algorithm ( S603). The encrypted measurement value data is delivered to the measurement processing unit 130.

  Next, the measurement processing unit 130 acquires latitude data and longitude data as position information regarding the current measurement apparatus 100 from the GPS receiving unit 110 (S604). The measurement processing unit 130 associates the measurement object ID 401 of the measurement object for which the measurement has been performed with the measurement data of the ground resistance value acquired for the measurement object and the latitude data and the longitude data as position information, thereby obtaining time information. At the same time, it is recorded in the measurement data table 400 (S605).

  The measurement processing unit 130 refers to the measurement object list and determines whether there is a measurement object to be subjected to the ground resistance measurement operation next (S606). Further, when it is determined that there is a measurement object to be measured (S606, No), the process returns to S602, and the ground resistance value is measured for the next measurement object.

  When it is determined in S606 that the measurement work has been completed for all the measurement objects in the measurement object list (S606, Yes), the measurement processing unit 130 records the measurement data table 400 including the ground resistance measurement value 402 and the position information 403. The transmitted data is transmitted to the management computer 200 (S607). This data transmission work can be executed by connecting the measuring apparatus 100 to the communication network NW after the day measurement work is completed and the staff returns to the office, for example. The above is the content of the processing executed by the measuring apparatus 100.

  Next, the contents of processing executed in the management computer 200 in response to the above will be described. First, the measurement data receiving unit 210 of the management computer 200 receives the data recorded in the measurement data table 400 from the measurement apparatus 100, and decrypts the encrypted ground resistance measurement value 402 (S608).

  Next, the measurement data processing unit 230 stores the ground resistance measurement value 402 received from the measurement apparatus 100 and the latitude data 403a and longitude data 403b as the position information 403 in the measurement target information table 500 held by itself. The latest measured ground resistance value 502, the latitude data 503a and the longitude data 503b, and the measurement object ID 501 are compared as a key (S609).

  As a result of the comparison, the measurement data processing unit 230 determines whether there is an abnormality in either the ground resistance measurement value 402 or the position information 403 (latitude data 403a, longitude data 403b) (S610). (S610, Yes) The ground resistance value measurement data received from the measuring apparatus 100 is stored in the measurement object information table 500, and the abnormality detection information is output through the output unit 205 of the management computer 200 (S612).

  The abnormality detection information includes a deviation exceeding a predetermined allowable value from the latest ground resistance measurement value 502 or the reference position information 503 with respect to the ground resistance measurement value 402 and the position information 403 recorded for a certain measurement object ( When a deviation is detected, an abnormality has occurred in the grounding state of the measurement object, or in fact, an object different from the electric workpiece specified by the measurement object ID 401 is regarded as the original measurement object. It is output in order to reliably capture the fact that the measurement work has been mistaken. The abnormality detection information is displayed and output to the administrator through a display device as the output unit 205 of the management computer 200, or is printed out by an output device such as a printer. Based on the abnormality detection information, the administrator can make countermeasures such as re-measurement and grounding state inspection on the measurement object in which the abnormality is detected.

  When it is determined in S610 that there is no abnormality in both the ground resistance measurement value 402 and the position information 403 (S610, No), the measurement data processing unit 230 obtains all the ground resistance measurement values 402 received from the measurement apparatus 100. The measurement object is associated with the measurement object ID 501 and recorded in the measurement object information table 500 (S611). Above, the process in the management computer 200 is complete | finished.

  In the present embodiment, latitude data 403a and longitude data 403b are acquired as position information 403 from the GPS receiver 110 provided in the measurement apparatus 100 and recorded in the measurement data table 400. Thus, when measuring the ground resistance value for each measurement object ID 401, a digital image of the electric workpiece that is the measurement object may be recorded. In this case, if metadata is embedded in the image data in, for example, Exif (Exchangeable image file format) format, GPS data (latitude, longitude, altitude) can be recorded in the metadata. In addition to the functions of the above-described embodiment, image data can be used.

  For example, the following types of image data can be used. For example, the measurement object information table 500 held in the management computer 200 stores the image data (control image data) of the measurement object previously captured in association with each measurement object ID 401. When the measurement object is measured, an attendant obtains image data of the measurement object together with the ground resistance value measurement using a digital camera with a GPS function or the like (implemented in conjunction with S602 in the processing flow of FIG. 6). can do).

  The acquired image data is recorded in the measurement data table 400 in association with the measurement object ID 401 by the measurement processing unit 130 and transmitted to the management computer 200 together with other data. On the other hand, in the management computer 200, the measurement data processing unit 230 compares the received image data with the ground resistance measurement value 402 and the GPS position information 403 with the image data stored in the measurement target information table 500. (This processing can be configured to be executed in S609 by the measurement data processing unit 230). In this case, the measurement staff may acquire image data for each measurement object from a predetermined fixed point (so as to have the same angle of view as the image data stored in advance in the measurement object information table 500). By using a software having a pattern matching function for image data, the image data acquired by the clerk and the image data captured in advance are collated, so that the GPS position information 403 cannot be identified. As for the measurement object installed in the vicinity, it is possible to confirm whether or not the clerk has properly recognized and carried out the measurement.

  By setting it as such a structure, it can be confirmed appropriately whether the measurement operation | work was implemented without the misrecognition also about the some measuring object installed adjacently as mentioned above.

  In the above embodiment, only latitude data and longitude data are used as GPS data. However, altitude data is also acquired from the GPS receiver 110 of the measuring apparatus 100 on the premise that sufficient accuracy is obtained in practice. If it is configured to be used, it is possible to appropriately discriminate even a measurement object that is installed close to the plane based on the installed altitude difference.

  In the above embodiment, the configuration and the like have been described on the assumption that the measuring apparatus 100 is a ground measurement meter. However, the ground resistance measurement unit 120 in FIG. 2 is used to measure other characteristic value measuring means, for example, insulation resistance. By using the insulation resistance measuring unit, it is possible to reliably measure not only the ground resistance value but also various other electrical characteristic values.

  As described above, according to the present invention, as described in connection with the embodiment, various characteristic values of a large number of electric workpieces installed in a wide range can be reliably measured without error.

  In addition, this invention is not limited to said embodiment, A various change is possible in the range which does not deviate from the summary.
