This means that things (sensors, etc.) other than information / communication equipment such as computers have communication functions, are connected to the Internet, communicate with each other, and perform automatic recognition, automatic control, and remote control (non-patent literature) 1). That is, the output of various sensors is automatically transmitted to the first device / equipment (object) via the Internet, and the second device / equipment etc. from the first device / equipment (* deletion, the same applies to the following *) ( An operation signal for operating the object is sent to the second device / device via the Internet, and the second device / device is controlled via the Internet. In this way, signals are automatically transmitted and received between the devices and devices, and the devices and devices can be automatically controlled (a person can assist the control). Here, the first device / device functions as a controller for the second device / device.

  In the past, devices and devices that function as controllers for IoT had to be assembled on site. In other words, bring the assembly kit to the measurement site, attach the sensor to the measurement object, lay the wiring from the sensor to the device / equipment that functions as the controller, and connect the A / D converter, amplifier, CPU, memory, etc. to the electrical circuit It was attached to an assembly board, installed on a device / equipment that functions as a controller, and further used as a device / equipment that functions as a controller for IoT by attaching an interface, display, keyboard, mouse, and the like.

As described above, since it has been necessary to assemble and use an apparatus / device functioning as a controller for IoT, there is a problem that it takes time to measure. This is especially true when problems such as wiring errors occur during assembly.
On the other hand, if it is possible to transport the device / device itself that functions as a pre-assembled controller, the time until measurement can be saved. Moreover, when respond | corresponding to a some measurement position, there exists an advantage that the apparatus and apparatus which function as a controller in order can be conveyed to each measurement position, and can measure immediately.

  An object of the present invention is to enable transportation of a device / equipment itself that functions as a pre-assembled controller when using the device / equipment that functions as a controller for IoT.

Therefore, the applicant does not intend to limit the scope of rights to development and educational equipment.
The Internet is a communication network that uses TCP / IP as a communication protocol. However, an IoT device is often connected to an intranet (for example, a wireless LAN or a wired optical LAN), and often collects sensor data and controls devices and devices. Many of these intranets use TCP / IP, and a wireless LAN or a wired optical LAN using these TCP / IP is also included in the “Internet”.

[Internet of Things]
FIG. 1 is a diagram for explaining the concept of the Internet of things.
IoT is an abbreviation for Internet of things and is called the Internet of Things. Not only the objects (devices / equipment) T1 to T4 are connected via the Internet I, but the objects T1 to T4 themselves transmit signals to the Internet I, and the objects T1 to T4 mutually transmit signals via the Internet I. Are communicating. FIG. 1 shows that output signals from the sensors S1 to S5 are output to the Internet I via the gateway G, and signals from the Internet I are input to the objects T1 to T4 via the gateway G. The gateway G absorbs protocol differences between different networks. For example, the wireless standard IEEE802.15.4 suitable for a wireless sensor network is converted to WiFi, 3G / LTE, Ethernet (registered trademark), etc. Connect to. Further, the addresses of the objects T1 to T4 are assigned to the IP addresses using IPv6 or IPv4. In addition, the signal from the Internet I is converted into a signal suitable for an apparatus / device that functions as a controller for controlling the objects T1 to T4.

〔sensor〕
With the development of sensor technology and Internet communication technology, the output of various sensors S1 to S5 can be transmitted via the Internet I to devices and devices that function as controllers. The sensors S1 to S5 have various physical quantities such as voltage, current, pressure, acceleration, air temperature, water temperature, flow rate, radiation dose, frequency, object shape / dimension, color, light, sound / sound, image, physical properties (hardness, viscosity. Etc.) can be detected. In Figure 1, a sensor, a temperature sensor S1, the humidity sensor S2, alarm sound microphone S3, illustrating a video camera S4, CO ₂ sensor S5. In many cases, the sensor output is input to the gateway G via a wireless network. However, in the case of an optical sensor, the measured analog signal is directly input to the gateway G, or the digital signal obtained by analog / digital conversion of the measured analog signal is gatewayed. Enter in G.

  In this embodiment, the interface between the IoT device and the Internet is simply referred to as a reception interface and a transmission interface, and the interface that connects the output signals of the sensors S1 to S5 to the Internet I is referred to as a second transmission interface. An interface that connects a device that controls the measurement targets of the sensors S1 to S5 to the Internet I and receives a control signal is called a second reception interface, and the IoT device sends an output signal of the sensors S1 to S5 to an intranet (wireless LAN, An interface for receiving via a wired LAN or the like is called a third receiving interface, and if necessary, an interface for connecting a device for controlling the measurement target of the sensors S1 to S5 to the intranet and transmitting a control signal. 3rd transmission And that the interface. At each of these interfaces, the gateway G converts the signals of devices, devices, and sensors including IoT devices so as to conform to the Internet I protocol TCP / IP. FIG. 1 exemplifies lighting equipment T1, rice cooker T2, air-conditioning equipment T3, and television recorder T4 as objects (apparatus / equipment).

[Development and educational equipment for IoT]
The IoT device 10 according to the present invention receives a sensor output signal via the Internet I, performs a predetermined process, and then transmits a control signal (command) and / or data via the Internet to a device / device connected to the Internet. Thus, the device / device is controlled to perform some processing. The Internet refers to a communication line network that uses TCP / IP as a communication protocol. TCP / IP is often used for intranets (wireless LANs, wired optical LANs, etc.) connected to IoT devices or sensors, and these intranets are also included in the “Internet”.

  The IoT device 10 according to the present invention includes an interface unit 14 that functions as an interface for transmitting and receiving data and signals to and from the Internet I, an arithmetic processing unit 12 that performs arithmetic processing on various types of data, and data and arithmetic received by the interface unit 14. The storage unit 13 stores the data processed and edited by the processing unit 12 and stores a program for controlling the IoT controller, the operation unit 16 for an operator to input data or commands, and the arithmetic processing unit 12. As a result of the arithmetic processing, the display unit 17 that displays the input command / data, the interface unit 14, the storage unit 13, the arithmetic processing unit 12, the display unit 17, and the operation unit 16 are controlled to form the IoT device 10. The control part 11 which exhibits this function is provided. Further, the interface unit 14, the storage unit 13, and the arithmetic processing unit 12 are mounted so as to be adjustable, and the electric circuit assembly board 18 on which the control unit 11 and the power switch 15C are mounted. And a component case 19 having a grip portion 41 for gripping. The display unit 17, the operation unit 16, and the electric circuit assembly board 18 are not fixed to the component case 19, and the electric circuit assembly board 18 is not covered with a personal computer casing.

Since each of the above components is mounted on the electric circuit assembly board 18 and accommodated in the component case 19 to be transported, the IoT device 10 itself assembled in advance can be transported when the IoT device 10 is used. In addition, the time until measurement can be saved. In addition, there is an effect that troubles due to wiring mistakes can be eliminated.
Moreover, since each part can be increased or decreased without being fixed, the flexibility is high. For example, the device may be assembled either inside or outside the component case. If the installation location can be widened, the IoT device can be assembled outside the component case.
The program can be rewritten. This indicates that a plurality of jobs are possible with one terminal. For example, a household management job and a qualification acquisition job can be executed by time sharing. In addition, applications and databases connected to the Internet can be used, and the application is expanded. For example, it is possible to refer to a library of animal and plant illustrations, a food and nutrition list, and a map of each country.

Thus, since each part is not fixed to the component case 19, as long as each part can be stored in the component case 19, the degree of freedom of design is large, and there is a possibility that a device incorporating various applications or accessories can be realized. is there. Depending on the application, the overall dimensions can be combined into an arbitrary size. It is also possible to carry the electric circuit assembly board 18 by rearranging or exchanging it. The component case 19 can typically use an attache case, but is not limited to this, and may be a case that can carry a larger load such as a trunk as long as it can be carried manually. In addition, for example, the display and the keyboard can be downsized to form a component case smaller than the attache case.
The high flexibility of IoT devices is very convenient for product / system development. Moreover, since the components can be seen, it is easy to understand the configuration of the device, which is convenient for education.

After the above parts are arranged at appropriate positions in the component case 1 or outside the component case 19, the reception interface 14A and the transmission interface 14B are connected to the Internet I, and the power switch 15C is turned on to operate. It becomes possible.

  Students carry IoT development and educational equipment 10 and carry them with them when they go to school. There are potted plants at home. In the plant flower pot 26, a digital thermometer S1 and a digital hygrometer S2 are set. The digital thermometer S1 measures the temperature in the soil in the flower pot, and the digital hygrometer S2 measures the humidity in the soil in the flower pot. The digital thermometer S1 and the digital hygrometer S2 are connected to the second controller 21 via a wireless LAN or a wireless public line, and the second controller 21 is connected to the Internet I. The digital thermometer S <b> 1 and the digital hygrometer S <b> 2 display the temperature and humidity in the soil as digital values on their respective displays, and transmit the digital values of the temperature and humidity in the soil to the second control unit 21. When the digital thermometer S1 and the digital hygrometer S2 are output, otherwise, the second control unit 21 converts the output signals of the digital thermometer S1 and the digital hygrometer S2 into a protocol compatible with the Internet I to the Internet I.

FIG. 3 shows an example of the appearance of the IoT development and educational device 10 according to the first embodiment. FIG. 3A shows an example of the appearance of the IoT development and educational device 10, and FIG. 3B shows a schematic cross-sectional view of the electric circuit assembly board 18.
Each unit constituting the IoT development and educational device 10, that is, the interface unit 14, the storage unit 13, the arithmetic processing unit 12, the display unit 17, the operation unit 16, the control unit 11, and the electric circuit assembly board 18 (interface unit 14 The storage unit 13 and the arithmetic processing unit 12 are mounted on the electric circuit assembly board 18). The component case 19 is provided with a grip portion 41, and the user carries the component case 19 containing the respective portions with the grip portion 41.

  First, the operation unit 16 such as the keyboard 16A and the mouse 16B and the power adapter 15A or the battery 15B are housed in the box side of the component case 19. Next, the electric circuit assembly board 18 is formed in a U shape as shown in a cross section in FIG. 3B, and the interface unit 14, the storage unit 13, and the arithmetic processing unit 12 are formed on the upper plane portion. The mouse 16B and the power adapter 15A or the battery 15B fit under the electric circuit assembly board 18. Next, a cover plate 44 that covers most of the electric circuit assembly board 18 and the periphery of the keyboard 17A and mounts the power connector 43 is accommodated (this cover plate 44 can be omitted. The connector 43 is mounted on the electric circuit assembly board 18). For example, a liquid crystal display 17 </ b> A is housed as the display unit 17 on the lid side of the component case 19. Moreover, when there are many interface parts 14, the memory | storage parts 13, and the arithmetic processing parts 12, you may make the electrical circuit assembly board 18 2 steps | paragraphs (or multistage).

Instead of the keyboard 16A, the keyboard may be displayed on the liquid crystal display 17A or a small second display (not shown) and operated with a touch pen.
The power adapter 15A converts the voltage of a 100V commercial power source into a DC voltage (typically 5V) suitable for the IoT development and educational device 10 and uses it. Instead of the power adapter 15A, a battery 15B having an appropriate DC voltage (typically 5V) may be used for the IoT development and educational device 10.
If comprised in this way, each part can be easily accommodated in the component case 19. FIG.

  Since each part of the IoT development and educational device 10 can be stored and transported in the component case 19, the student can carry it at school. At school or at an appropriate time, you can start a plant breeding program and water your plants. Thereby, in using the IoT device 10, there is an effect that the IoT device 10 assembled in advance can be transported. Also, if each component is arranged so that it can be used immediately after opening the component case 19, there is no need to assemble after opening the component case 19 (the mouse 16B is placed under the electric circuit assembly board 19). It is sufficient to take out, connect the receiving interface 14A and the transmitting interface 14B to the Internet I by inserting the terminals into the Internet I, and turn on the power switch 15C. In the case of connecting to the Internet by radio, the terminal insertion may be omitted in many cases.) , Time to measurement can be saved. Since it is not necessary to assemble after opening the component case 19, the time until measurement can be saved. In order to be able to use the component case 19 immediately after opening the component case 19, for example, the keyboard 16A can be seen when the component case 19 is opened, or the liquid crystal display 17A can be raised to the lid side. In addition, there is an effect that troubles due to wiring mistakes can be eliminated.

In addition, since the program storage unit 13A can be rewritten, it is possible to perform a plurality of jobs by sharing time with a single terminal. For example, during class time, a class program different from the plant training program can be activated and used for class.
Moreover, since each part can be increased or decreased without being fixed, the flexibility is high. For example, the device may be assembled either inside or outside the component case 19. If the installation location can be widened, the device can be assembled outside the component case. For example, the plant growing program can be used by being assembled in the component case 19, and the lesson program can be used by being assembled on the desk outside the component case 19. In this case, a plurality of displays may be used, the teaching materials of the lesson may be displayed on the main display, and the reference book obtained from the Internet may be displayed on the secondary display. In addition, applications and data connected to the Internet I can be used, and the application spreads. You can refer to the library of animal and plant catalogs, food and nutrition list, and maps of each country.

It is also convenient for testing. If a test question is displayed from the distributed USB memory and the response is recorded in the USB memory and collected, the response cannot be rewritten. In addition, scoring and statistical processing becomes easy. It is also possible to have a book written in an unlearned language translated and read using a translation application.
In addition, if the operation method of the IoT device is described on a specific web page on the Internet I (for example, a web page of a manufacturer, a sales agent, etc.), distribution of the instruction manual can be omitted. Further, it is preferable to make it downloadable because it is easy for the operator to use.

As described above, the present IoT device can always be carried and used. It has the advantage that it can be used immediately after opening the case. Further, the electric circuit assembly board 18 is mounted so that components such as an electric circuit can be increased and decreased, and is not fixed to the component case 19, and the electric circuit assembly board 18 is not covered with a personal computer casing. The program storage unit can be rewritten. For this reason, it is rich in flexibility in repair and modification, and in the development of equipment. This is very convenient for device development. Moreover, since the components can be seen in the education, it is easy to understand software and hardware.
As described above, according to the present embodiment, in using the IoT device, there are various effects in addition to the effect that the preassembled IoT device itself can be transported.

  FIG. 4 shows a configuration example of the IoT development and educational device 10A in the second embodiment. In the present embodiment, an example in which visual observation is added to the first embodiment will be described. A mechanism for using the video camera S3 to photograph the plant in the flower pot 26 and observing with the liquid crystal display 17A of the IoT device 10A is added.

  A video camera S3 is installed in front of the flower pot 26, and photographing is automatically performed at a predetermined time (for example, every one hour). The captured image data is transmitted to the control unit 11 via the second control unit 21, the Internet I, and the reception interface 14A, and stored in the sensor data storage unit 13B. Moreover, when a student wants to see, the picked-up image memorize | stored in the sensor data memory | storage part 13B by own operation can be displayed on the display 17 at a time, and can be observed. The student can grasp the growth state of the plant from the photographed image displayed on the display 17 and can confirm the amount of water to be supplied at a predetermined watering time as the calculation result displayed on the display 17. The amount of water to be supplied at a predetermined watering time is stored in the calculation result storage unit 13C. The student may operate the operation unit 16 to transmit a confirmation signal from the control unit 11 to the second control unit 21, considering the observation result of the photographed image, and the water supply time and / or the amount of water. May be sent after modification.

The second control unit 21 controls the supply of water to the flower pot 26 based on the confirmation signal transmitted from the control unit 11, the time of water supply and / or the amount of water. In the case of the confirmation signal, the amount of water is supplied at a predetermined water supply time.
Various information can be obtained by using the visual sensor (video camera) S3. Not only the dimensions and shape of the measurement target, but also the color and brightness are understood, and the growth status is also known compared to past images. In addition, there is a possibility that the situation such as whether the outside is clear or rain, the stem is straight, whether the leaves are loose or dense, and whether there are insects, etc. may be understood. Then, by providing the data analysis unit 12A and analyzing the information to obtain necessary information, such as a growth rate, it is possible to provide students with scientific consideration materials.
It is also possible to obtain information on the growth of the same plant from the Internet I and deepen the discussion.

  Other configurations are the same as in the first embodiment, and as in the first embodiment, when the IoT device 10A is used, the pre-assembled development and educational device 10A itself can be transported, and the time until measurement is reduced. There is an effect that can be done.

  FIG. 5 shows a configuration example of the IoT development and educational device 10B in the third embodiment. A present Example demonstrates the example which measures the radioactivity of several points with the radiation sensor 20B (20B1-20Bn).

In the present embodiment, the radioactive dose of γ rays is measured by the NaI scintillator 20B as a sensor. It is assumed that the sensor side converts it into a digital value and transmits it to the IoT device 10B via the Internet I. The NaI scintillators 20B1 to 20Bn are installed at a plurality of points, and the IoT device 10B sequentially fetches measurement data from the plurality of NaI scintillators 20B1 to 20Bn via the Internet I, and identifies each NaI scintillator 20B1 to 20Bn with an identification number #. It is stored in the sensor data storage unit 13B together with 20B1 to # 20Bn. At the same time, the position data from the GPS monitors 20C1 to 20Cn (not shown) installed at the positions of the NaI scintillators 20B1 to 20Bn are stored in the sensor data storage unit 13B in association with the identification numbers # 20B1 to # 20Bn.
The operator can observe the radiation dose stored in the sensor data storage unit 13B and the position information of the NaI scintillators 20B1 to 20Bn on the display 17 at an appropriate time. It can be displayed on the display 17 in a time-change graph format and a map format.
The transmission interface 14B is not necessary if only data is to be viewed, but is necessary if an instruction to open / close a measurement location window, for example, is transmitted.

  Other configurations are the same as those in the first embodiment, and in the same manner as the first embodiment, when the IoT device is used, the IoT device itself assembled in advance can be transported and the measurement state can be observed anywhere.

  FIG. 6 shows a configuration example of the IoT development and educational device 10C in the fourth embodiment. In this embodiment, an example in which a voltage / current inspection of electrical wiring is performed will be described. For example, in an exhibition hall (event hall), electrical wiring work to exhibition equipment and lighting equipment is performed. Then, it is necessary to inspect whether the planned voltage / current is realized for the voltage / current of the installed wiring.

  The inspector carries IoT development and educational equipment 10C and carries it around the exhibition hall. Voltage probes 20C1 to Cn and current probes 20D1 to Dn are brought separately and set at predetermined measurement points. The voltage probes 20C1 to Cn and the current probes 20D1 to Dn output analog values. Outputs from the voltage probes 20C1 to Cn and the current probes 20D1 to Dn are taken into the IoT device 10C via the third reception interface 14C via the intranet (wireless LAN). In the IoT device 10C, first, the acquired analog value is stored in the analog value storage unit 13BA of the sensor data storage unit 13B. When the analog value is small, the signal is amplified through an amplifier 19A (not shown) and stored. The analog value is stored in association with the measurement position on the wiring diagram. Voltage and current are measured at a plurality of scheduled measurement points, and the measured values are stored in the analog value storage unit 13BA. Next, the measurement value stored in the analog value storage unit 13BA is subjected to analog / digital conversion through the analog / digital converter 19B, and stored in the digital value storage unit 13BD of the sensor data storage unit 13B. The digital value is stored in association with the measurement position on the wiring diagram. If there is a storage in the digital value storage unit 13BD, the storage in the analog value storage unit 13BA is not necessarily required.

  The operator can display the digital measurement value stored in the digital value storage unit 13BD on the display 17 in a timely manner in association with the measurement position of the wiring diagram by his / her own operation. The wiring diagram and the voltage and current values at the time of design are stored in the equipment design database 22A of the head office, and are read and compared via the Internet I (via the reception interface 14A and the transmission interface 14B). If the measured value is the same as the voltage value and current value at the time of design, it can be understood that there is no problem with the wiring. If they are different, contact a specialist in charge and re-route the wiring. The measurement value may be written in the device design database 22A via the Internet I and the transmission interface unit 14B.

Since each part of the IoT device 10C can be stored and transported in the component case 19, the inspector can carry around the exhibition hall. This is convenient when there is wiring work at multiple points. There is an effect that the IoT device 10C assembled in advance can be transported. If each component is arranged so that it can be used immediately after the component case 19 is opened, it is not necessary to assemble the component case 19 after the component case 19 is opened, thereby reducing the time until measurement. In addition, there is an effect that troubles due to wiring mistakes can be eliminated.
In addition, since the program storage unit 13A can be rewritten, it is possible to perform a plurality of jobs by sharing time with a single terminal. For example, it is possible to activate the cost estimation program at an appropriate free time of the wiring check program, access the price list database of the head office, and issue an estimation slip at an early stage.

  Moreover, since each part can be increased or decreased without being fixed, the flexibility is high. For example, the device may be assembled either inside or outside the component case 19. If the installation place can be widened, the apparatus can be assembled outside the component case 19. For example, the wiring check program can be used while being assembled and carried inside the component case 19, and the cost estimation program can be used after being assembled on the desk outside the component case 19. In this case, a plurality of liquid crystal displays 17A may be used, an estimate slip may be displayed on the main display, and a price list acquired from the head office may be displayed on the secondary display. Applications and databases that are connected to the Internet I can be used, and the application spreads. You can refer to electronic parts handbooks, electronic device web pages of various companies, JIS standards, and the like. In addition, programs and data existing in the Internet I such as an authentication program, a numerical calculation program, a structure analysis program, and an inventory management program can be taken in as necessary.

  Other configurations are the same as in the first embodiment, and as in the first embodiment, when using the IoT device, the preassembled IoT device 10C itself can be transported, and the time to measurement can be reduced. Play.

  FIG. 7 shows a configuration example of the IoT development and educational device 10D in the fifth embodiment. In the present embodiment, an example of performing product defect inspection and product selection will be described.

  The product is transported on a belt. In order to monitor the product transported on the belt, a video camera 20D is installed as a sensor, and is constantly monitored by the video camera 20D. The size and color of the apple as a product is inspected, and the product is selected according to the size and color. Also, apples found to have defects such as scratches, worms, corrosion, and shape distortion are removed. For example, after extracting an outline from an image of an apple, the width is measured and classified into four stages of 8 cm or less, 8 cm to 10 cm, 10 cm to 12 cm, 12 cm or more, and the colors are 3 in red, yellow, and green. Classify into types. Classification is made into 12 groups in total and 15 groups of defective products in which defects such as scratches, worms, corrosion, and shape distortion are found, and classification marks Ap1 to Ap15 are given. When the product is conveyed on the belt and reaches a predetermined position for each group, the product is put into a box by an extrusion tool.

  The image of the video camera 20E is taken into the IoT device 10D via the intranet (wired optical LAN) and the third reception interface unit 14C. In the IoT device 10D, for example, a digital value of a CCD image signal captured via the wired optical LAN is stored in the sensor data storage unit 13B. The digital value is stored in association with the identification number of each product (apple). Handling instructions and product selection criteria relating to measurement are stored in the product database 22B of the head office, and the product database 22B is referred to via the Internet I during measurement. Products (apples) are selected according to the dimensions and colors stored in the sensor data storage unit 13B. The selection result may be written in the product database 22B.

Various information can be obtained by using the visual sensor (video camera) 20E. Not only the dimensions and shape of the measurement target, but also the color and brightness are understood, and the growth status is also known compared to past images. If it is important to analyze the relationship between the field conditions and the growth situation, it is important to obtain the degree of correlation, so the correlation function may be downloaded from the Internet, but the correlation function is stored in the program storage unit 13A together with the analysis program. It is more desirable to keep it.
From the Internet I, for example, a program that performs parallel high-speed computation for computation is used. A structural analysis program, a similarity evaluation program, or the like may be used. However, it is desirable to create a list of access destinations for programs that are desired to be used from the Internet I so that they can be accessed immediately.

  Other configurations are the same as in the first embodiment, and as in the first embodiment, when the IoT device is used, the preassembled IoT device itself can be transported, and the time until measurement can be reduced. .

  Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and it is obvious that various modifications can be made to the embodiment.

  For example, as a modification of the second embodiment, an example in which a visual image is acquired by attaching a camera to a cleaning robot can be considered. If you see trash, continue cleaning. If you do not see it, stop cleaning and continue moving. If you can see trash, resume cleaning. Since the cleaning course has been decided, if an image different from the normal one appears on the way, it is determined that there is an abnormality and a warning is notified via the Internet. An attitude control signal is transmitted, and if it recovers, it returns to the course and continues cleaning. Stop cleaning if not recovered.

  Further, for example, in the above embodiment, the example of referring to the company data from the Internet has been described. You may refer to the reference material. When connecting an IoT device, a control device, or a sensor via the Internet, a public line may be used as the Internet, an intranet may be used, or both may be routed. Further, a wired optical cable or a wireless transceiver may be used for connection between the IoT device, the control device, or the sensor and the Internet or the intranet. For example, the IoT device is not stationary. For example, while moving by car, from the rear seat IoT development and education device via the public wireless network via the Internet, office, store It is also possible to access equipment in factories and control local equipment. In addition, the type and number of sensors to be connected can be freely changed. The object to be controlled and the physical quantity to be controlled can be freely changed.
