Description

[Technical Field]

[0001] The present disclosure relates to a sensor system, an information processing device, an information processing method, and a child tag and a parent tag included in the sensor system, which collect status data of a plurality of sensors installed in a manufacturing machine. [Background technology]

[0002] In the field of manufacturing machinery, sensors are installed at various locations. The results of the sensor detection are input to a dedicated controller or computer. In recent years, there has been a demand for using various sensors to collect data that changes from moment to moment in real time (see Patent Document 1).

[0003] There are many different requirements for sensors depending on the equipment, objects, buildings, structures, etc. to which they are attached, and they must be able to meet a wide range of requirements, including the location of attachment and the data required. With conventional sensor devices, when changing operational settings, such as changing the radio band, in response to such sensor requirements, it is necessary to connect them using direct methods such as connectors or soldering, and then rewrite the settings, which creates operational burdens.

[0004] Furthermore, when attaching sensors to multiple objects to collect large amounts of data, or installing many sensors on a single object to manage their operation, if the number of sensors reaches the tens or hundreds, the burden of changing the settings becomes even greater, making it difficult to operate in reality.

[0005] While wireless sensor configuration and data collection could be performed, this method consumes a lot of power and requires a power line or battery, which eliminates the benefits of wireless communication.Furthermore, there are concerns about the reliability of the system, such as the possibility of data loss due to interference from wireless communications or overlapping reception timing.

[0006] For the reasons mentioned above, the use of sensors to enable IoT in a wide range of applications, including equipment, objects, buildings, and structures, is still in its infancy and is often limited in scope. If it were possible to wirelessly collect and analyze a sufficient amount of sensor data from many sensors, it would be possible to make a significant contribution to improving the productivity of equipment, maintenance management, and safety management of vehicles and structures.

[0007] As an improvement to the above-mentioned problems, a wireless sensor terminal, such as that described in Patent Document 2, is known that reduces power consumption by optimizing and setting the conditions for acquiring vibration sensor data, and transmits sensor data wirelessly using power generating elements such as solar cells, piezoelectric elements, and Peltier elements.

[0008] Also, a wireless sensor system such as that disclosed in Patent Document 3 is known in which a delay is provided in the timing of data transmission from each wireless sensor, thereby preventing the generation of sensor data traffic. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Japanese Patent Application Publication No. 2019-46293 [Patent Document 2] Japanese Patent Application Publication No. 2018-18408 [Patent Document 3] Japanese Patent Application Publication No. 2023-23349

[0010] However, the technology disclosed in Patent Document 2 raises concerns that large amounts of sensor data may interfere with wireless communication, resulting in data loss. This problem is particularly likely to occur during the process of determining the sampling frequency for vibration sensor data, as the amount of data required for condition setting increases, lengthening the data transmission time. Furthermore, when the amount of data is large, a lot of power is consumed for sensing and data transmission, which can lead to problems such as data being interrupted during transmission due to the power generated by the power generating element, or data being unable to be transmitted due to insufficient power. Furthermore, the technology does not support a wide variety of sensors other than vibration sensors, and is not designed to meet a wide range of sensing needs.

[0011] Furthermore, the technology disclosed in Patent Document 3 requires separate equipment for calculating and setting the delay time in addition to the wireless slave device (sensor terminal) and master device (reader) in order to set the delay wirelessly to prevent interference, resulting in a large and costly configuration. Also, because sensor operation settings other than the delay time are not set wirelessly, although communication interference can be prevented, there are problems such as an inability to accommodate diverse sensing needs and the time and effort required to change sensor settings. Summary of the Invention [Problem to be solved by the invention]

[0012] Multiple sensors are installed in various parts of manufacturing machinery. To constantly monitor these multiple sensors in time synchronization, and to achieve this, a stable power supply is required. Furthermore, the system features automatic processing, such as thorough power management, multi-stage control based on the required operating time of each sensor, data acquisition time, microcomputer information processing time, communication time, data storage time, reception time, transmission time, and other constantly changing conditions, and by operating in sleep mode or minimizing the power supply to unnecessary operating parts, it is possible to reduce power consumption to 1 / 10 to 1 / 1000. Another feature is that even if the power goes out during processing, the processing will be paused until the power is restored, and will continue once the power is restored.

[0013] In view of the above circumstances, an object of the present invention is to provide a convenient and highly reliable wireless sensor that can constantly monitor multiple sensors in time synchronization, supply stable power to the sensors, and change sensor operation settings wirelessly. [Means for solving the problem]

[0014] A sensor system according to an embodiment of the present disclosure includes: a plurality of slave tags each connected to a plurality of sensors installed in a manufacturing machine, each having a processor and a wireless communication unit; a parent tag (reader / writer) capable of wirelessly communicating with the plurality of child tags (sensor-equipped tags); an information processing device to which the parent tag (reader / writer) is connected; A sensor system comprising: The parent tag transmits a data transmission request and setting parameters such as sensing content and period to the plurality of child tags in response to a request from the information processing device; When the processor of each child tag receives the data transmission request and the setting parameters, it acquires status data including a sensor identifier and a sensor value of the sensor connected to the child tag according to the received setting content, and transmits the status data to the parent tag via the wireless communication unit; the parent tag receives a plurality of status data from the plurality of child tags, generates a message including the plurality of status data, and transmits the message to the information processing device; The information processing device receives the message, generates a GUI that displays multiple sensor values ​​obtained by the periodicity and measurement settings of individual child tags included in the multiple status data included in the message, aligned with common time information, and outputs the GUI to a display device, making it possible to use the sensor data for alert display, analysis, judgment, and action instructions using AI, etc.

[0015] This allows multiple sensors to be monitored constantly in time synchronization.

[0016] When the parent tag transmits setting parameters such as sensing content and cycle changes, the child tag notifies the parent tag that the data has been received successfully and the setting changed, and when the child tag transmits status data including a sensor identification value and a sensor value, the parent tag notifies the child tag that the data has been received successfully, and if the notification cannot be confirmed, requests retransmission. This can prevent errors in setting changes and sensor data transmission and reception and increase communication reliability, making it possible to make the system usable for applications requiring reliability.

[0017] Each slave tag is a semi-active sensor tag (RFID tag) and includes a power generation unit and a power storage unit that stores electricity generated by the power generation unit and supplies the electricity to the processor and the sensor. the parent tag is an RFID reader / writer, When the child tag receives the data transmission request, the child tag may be driven by electricity stored in the power storage unit and read out the sensor value of the sensor driven by electricity stored in the power storage unit.

[0018] By having a power generation unit and a power storage unit in the child tag, it is not necessary to supply electricity to the child tag and the sensor via a wire, wiring is not required, and there is no risk of the power supply being cut off due to a broken wire.

[0019] the status data further includes a voltage value indicating the amount of power generated by the power generation unit of each slave tag; The message further includes radio wave intensity in addition to the voltage value, The GUI may further display the voltage value and the radio wave intensity in association with the sensor identifier included in the message.

[0020] Therefore, if the user looks at the GUI and sees that the voltage value and radio wave strength are smaller than the specified values ​​required to obtain the required sensor data, the user can simply move the slave tag to an installation position where the slave tag's radio wave strength and power generation unit can obtain a sufficiently large amount of power generation.

[0021] The child tag may be installed on a manufacturing machine, facility, vehicle, or structure where a sensor connected to the child tag is installed.

[0022] This allows the power generation unit to generate electricity using energy (vibration, temperature, heat, light, electromagnetic waves, induced current, etc.) generated by the manufacturing machine in which the slave tag is installed.

[0023] The power generation unit is a temperature difference power generation device that generates electricity using the temperature difference between the temperature of the manufacturing machine on which the slave tag is installed and the outside air temperature; A vibration power generation device that generates power from vibrations of the manufacturing machine on which the child tag is installed, and / or Photovoltaic power generation devices that generate electricity using the light around the child tag, power generation devices that use electromagnetic waves, power generation devices that use electromagnetic induction, and other power generation devices may include:

[0024] Temperature difference power generation devices generate electricity when manufacturing machinery operates and generates heat. Vibration power generation devices generate electricity when manufacturing machinery has vibrating parts such as motors and operates and vibrates. Photovoltaic power generation devices are attached to the exterior of manufacturing machinery and generate electricity when the lights are on inside the factory. Electromagnetic wave power generation generates electricity from devices that generate electromagnetic waves, such as mechanical devices and motors. Electromagnetic induction methods include electromagnetic induction from motors and using dedicated coils. As such, temperature difference power generation devices, vibration power generation devices, and photovoltaic power generation devices, electromagnetic waves, and electromagnetic induction have different power generation conditions. The power generation unit may have two or more of several different types of power generation devices, namely temperature difference power generation devices, vibration power generation devices, and photovoltaic power generation devices, to complement each other.

[0025] The power storage unit may be a capacitor, an all-solid-state battery, or other secondary battery.

[0026] Since capacitors and solid-state batteries have a much longer life (semi-permanent) than batteries (e.g., lithium-ion batteries) and are small, it is preferable that the power storage unit be a capacitor or an all-solid-state battery. By using a capacitor or an all-solid-state battery as the power storage unit, the slave tag can be made smaller, and the slave tag and sensor can be used substantially semi-permanently.

[0027] The status data further includes radio wave intensity of the wireless communication unit of each slave tag. The message further includes the radio wave intensity, The GUI may further display the radio wave intensity in association with the sensor identifier included in the message.

[0028] Therefore, if the user looks at the GUI and sees that the radio wave intensity is lower than a predetermined value, the user can move the child tag to a position where the radio communication unit of the child tag can obtain radio wave intensity strong enough to communicate with the parent tag.

[0029] The sensor system may further comprise the plurality of sensors.

[0030] The sensor may be externally connected to the daughter tag or may be built into the daughter tag.

[0031] According to yet another aspect of the present invention, there are provided an information processing device, a child tag, and a parent tag included in the sensor system, and an information processing method executed by the sensor system. [Effects of the Invention]

[0032] According to the present invention, a convenient and highly reliable wireless sensor is provided that can constantly monitor multiple sensors in time synchronization, supply stable power to the sensors, and change sensor operation settings wirelessly.

[0033] The effects described here are not necessarily limited to those described herein, and may be any of the effects described in this disclosure. [Brief explanation of the drawings]

[0034] [Figure 1] 1 illustrates a configuration of a sensor system according to an embodiment of the present disclosure. [Figure 2] The child tag structure is shown below. [Figure 3] 1 shows an operation sequence of the sensor system. [Figure 4] An example of a GUI that displays vibration data is shown. [Figure 5] An example of a GUI that displays temperature data is shown below. DETAILED DESCRIPTION OF THE INVENTION

[0035] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0036] 1. Sensor system configuration

[0037] FIG. 1 shows the configuration of a sensor system according to an embodiment of the present disclosure.

[0038] The sensor system 1 includes a plurality of child tags 100, a parent tag 200, and an information processing device 300.

[0039] The multiple slave tags 100 are semi-active sensor tags (RFID tags). Hereinafter, the object 10 to be attached will be described as a manufacturing machine 10 as an example. The multiple slave tags 100 are each connected to multiple sensors 400 installed in the manufacturing machine 10. The manufacturing machine 10 may be, for example, a machine tool installed in a manufacturing factory. The multiple sensors 400 may be different types of sensors, such as vibration sensors, temperature sensors, pressure sensors, current sensors, rotation sensors, and humidity sensors, and may be sensors provided by different manufacturers. One sensor 400 may be connected to one slave tag 100, or two or more sensors 400 may be connected to one slave tag 100. The slave tag 100 and the sensor 400 may be detachably attached to the manufacturing machine 10 using, for example, adhesive tape (double-sided tape), bolts, screws, or magnets. The sensor system 1 may include multiple sensors 400. The sensor 400 may be externally connected to the slave tag 100 or may be built in.

[0040] The parent tag 200 is typically capable of wireless communication with multiple slave tags 100 via an external antenna 201. The parent tag 200 is connected to an information processing device 300, for example, via a USB connection. The parent tag 200 is an RFID reader, and is capable of wireless communication with multiple slave tags 100. The parent tag 200 and multiple slave tags 100 may use, for example, the UHF (ultra-high frequency band: 860 to 920 MHz) frequency band or the SHF (microwave band: 2.45 GHz) frequency band. Compared to other frequency bands, UHF has a longer communication distance of several meters, and SHF has a larger information capacity.

[0041] The information processing device 300 is a dedicated controller or a computer (desktop computer, laptop computer, tablet, etc.). The information processing device 300 collects data from a plurality of sensors 400 and a plurality of child tags 100 via the plurality of child tags 100 and parent tag 200, and displays a GUI showing the collected data on a display device 320 (built-in or external). The processor 310 of the information processing device 300 operates as a data collection unit 311, a time information setting unit 312, and a display control unit 313.

[0042] 2. Child tag configuration

[0043] Figure 2 shows the structure of a child tag.

[0044] The slave tag 100 has a power generation unit 110, a power storage unit 120, an installation surface 130, a processor 150, and a wireless communication unit 160 including an antenna 161. The slave tag 100 is a semi-active sensor (RFID) tag. When the processor 150 of the slave tag 100, which is a semi-active sensor (RFID) tag, receives radio waves from the parent tag 200, which is an RFID reader, via the wireless communication unit 160, it is activated by the electricity generated by the power generation unit 110 and stored in the power storage unit 120, and transmits radio waves to the parent tag 200 via the wireless communication unit 160.

[0045] The power generation unit 110 generates electricity using energy generated by the manufacturing machine 10 in which the slave tag 100 is installed. Specifically, the power generation unit 110 includes a temperature difference power generation device 111, a vibration power generation device 112, and a photovoltaic power generation device 113. The temperature difference power generation device 111 generates electricity from the temperature difference between the temperature of a heat-generating part (motor, etc.) of the manufacturing machine 10 in which the slave tag 100 is installed and the outside air temperature. The vibration power generation device 112 generates electricity from the vibration of a vibrating part (motor, etc.) of the manufacturing machine 10 in which the slave tag 100 is installed. The photovoltaic power generation device 113 includes a solar panel 114 installed and exposed on the outermost surface of the slave tag 100, and generates electricity from the light surrounding the slave tag 100. The temperature difference power generation device 111 generates electricity when the manufacturing machine 10 operates and generates heat. The vibration power generation device 112 generates electricity when the manufacturing machine 10 has a vibrating part such as a motor and operates and vibrates. The photovoltaic power generation device 113 generates power when the manufacturing machine 10 is attached to the exterior of the manufacturing machine 10 and the lights inside the factory are on. In this way, the temperature difference power generation device 111, the vibration power generation device 112, and the photovoltaic power generation device 113 have different power generation conditions. The power generation unit 110 may have two or more of the different types of power generation devices, the temperature difference power generation device 111, the vibration power generation device 112, and the photovoltaic power generation device 113, to mutually complement each other.

[0046] The power storage unit 120 stores the electricity generated by the power generation unit 110. The power storage unit 120 is typically a capacitor or an all-solid-state battery, but may also be a battery. Capacitors and all-solid-state batteries have a much longer life (semi-permanent) than batteries (e.g., lithium-ion batteries) and are also small, so the power storage unit 120 is preferably a capacitor or an all-solid-state battery. When the power storage unit 120 is a capacitor or an all-solid-state battery, the slave tag 100 can be made smaller, and the slave tag 100 and the sensor 400 can be used substantially semi-permanently. Furthermore, since the slave tag 100 has the power generation unit 110 and the power storage unit 120, there is no need to supply electricity to the slave tag 100 and the sensor 400 via a wire, so wiring is also unnecessary and there is no risk of the power supply being cut off due to a broken wire.

[0047] The slave tag 100 is installed on the object 10 to which it is to be attached. The installation surface 130 is the surface opposite the solar panel. The installation surface 130 is detachably installed on the object 10 to which it is to be attached using an attachment part such as adhesive tape (double-sided tape), bolts, screws, or magnets. The attachment object 10 may be, but is not limited to, a manufacturing machine, equipment, vehicle, structure, etc.

[0048] Each slave tag 100 can be operated in a state where its settings can be rewritten at any time, and measures have been taken to increase safety, speed up data exchange, and reduce current consumption. By providing a slave tag 100 with a switch, it is possible to prevent inadvertent rewriting. A state where settings can be rewritten at any time cannot be prevented in the case of malicious system-related behavior. As a countermeasure, a rewrite mode switch is physically attached when rewriting. This physical switch can be in various forms, and is not limited to contact switches, but can also be a non-contact switch, etc.

[0049] 3. Sensor System Operation

[0050] FIG. 3 shows the operation sequence of the sensor system.

[0051] The data collection unit 311 of the information processing device 300 transmits a data collection request and setting parameters such as sensing content and period to the parent tag 200 at regular sampling intervals (step S1). The sampling period, channel, number of samples to be acquired, etc. may be set in advance by the user using the UI of the information processing device 300.

[0052] Upon receiving a request from the information processing device 300, the parent tag 200 transmits a data transmission request and setting parameters such as sensing content and cycle to the multiple child tags 100. The transmission may be periodically (every few milliseconds) (step S2). Specifically, the parent tag 200 transmits a data transmission request by unicast to each of the multiple child tags 100 in turn. The transmission interval between data transmission requests to the multiple child tags 100 is, for example, a few microseconds, which can be considered to be substantially simultaneous and is negligible.

[0053] When the processor 150 of the slave tag 100 receives the data transmission request and the setting parameters from the parent tag 200, it is driven by the electricity stored in the power storage unit 120. The processor 150 drives the sensor 400 by the electricity stored in the power storage unit 120 (step S3) and reads the sensor value of the sensor 400 (step S4). The processor 150 acquires and generates status data to be transmitted to the parent tag 200 according to the received setting contents (step S5). The status data indicates the status of the sensor 400 and the slave tag 100, and specifically includes the sensor identifier and sensor value of the sensor 400, a voltage value indicating the amount of power generated by the power generation unit 110, and the radio wave intensity of the wireless communication unit 160. The processor 150 of the slave tag 100 transmits the generated status data to the parent tag 200 via the wireless communication unit 160 (step S6).

[0054] The parent tag 200 sequentially receives multiple status data from multiple child tags 100 via the antenna 201. If the parent tag 200 does not receive status data from a specific child tag 100 even after a predetermined period of time has elapsed since sending a data transmission request to that child tag 100, the parent tag 200 sends (retries) the data transmission request to that child tag 100 a predetermined number of times. The parent tag 200 generates a message including the multiple status data received from the multiple child tags 100 (step S7). That is, the message includes the sensor identifier and sensor value, voltage value, and radio wave intensity of the sensor 400 of each of the multiple child tags 100. The parent tag 200 transmits the message to the information processing device 300 (step S8).

[0055] When the parent tag 200 sends setting parameters such as sensing content and period changes, the child tag 100 notifies the parent tag 200 that the data has been received successfully and the setting has been changed. When the child tag 100 sends status data including the sensor identification value and sensor value, the parent tag 200 notifies the child tag 100 that the data has been received successfully. If the notification cannot be confirmed, the parent tag 200 can request retransmission.

[0056] The data collection unit 311 of the information processing device 300 receives the message from the parent tag 200. The time information setting unit 312 of the information processing device 300 assigns a common timestamp to the multiple sensor values ​​included in the multiple status data included in the message (step S9). In other words, the information processing device 300 regards the multiple sensor values ​​included in the message as sensor values ​​at the same time.

[0057] The display control unit 313 of the information processing device 300 generates a GUI and displays the GUI on the display device 320 (step S10). The GUI displays multiple sensor values ​​included in multiple status data included in the message in alignment with common time information, and may specifically be a time-series graph or a table. The information processing device 300 may use the sensor data for alert display, analysis, judgment, action instructions, etc. using AI or the like.

[0058] The GUI also displays a voltage value. The voltage value is displayed in association with the sensor identifier included in the message and indicates the amount of power generated by the power generation unit 110 of the child tag 100. Therefore, if the user looks at the GUI and sees that the voltage value is smaller than the predetermined value required to acquire the required sensor data, the user can simply move the child tag 100 to an installation position where the power generation unit 110 of the child tag 100 can generate a sufficiently large amount of power. Furthermore, if a sufficient voltage value is obtained for sensor operation, the settings of the sub-tag 100 can be changed wirelessly to collect more detailed data, or the number of sensors can be increased to improve the accuracy of analysis, thereby improving the convenience and reliability of the data.

[0059] The GUI also displays radio wave intensity. The radio wave intensity is displayed in association with the sensor identifier included in the message, and indicates the radio wave intensity of the wireless communication unit 160 of the child tag 100. Therefore, if the user looks at the GUI and sees that the radio wave intensity is lower than a predetermined value, the user can simply move the child tag 100 to a position where the radio wave intensity is strong enough for the wireless communication unit 160 of the child tag 100 to communicate with the parent tag 200.

[0060] According to the present invention, a plurality of sensors 400 can be constantly monitored in time synchronization, and power can be supplied to the sensors 400 stably.

[0061] 4. GUI Example

[0062] FIG. 4 shows an example of a GUI that displays vibration data.

[0063] GUI 500 shows time series graphs 510-540 and table 550. Time series graphs 510-540 and table 550 display multiple sensor values ​​(vibration sensor values ​​on three axes: x, y, and z) obtained from different sensors 400, synchronized with common time information (horizontal axis of the graph, time column 551). The time information shown in time column 551 of table 550 is the time information indicated by the timestamp (step S9).

[0064] Specifically, the time series graph 510 and column 552 of the table 550 synchronously show average values ​​(mG) on the three axes x, y, and z. The time series graph 520 and column 553 of the table 550 synchronously show peak values ​​(mG) on the three axes x, y, and z. The time series graph 530 and column 554 of the table 550 synchronously show root mean square (RMS) values ​​(mG) on the three axes x, y, and z. The time series graph 540 and column 555 of the table 550 synchronously show crest factor (CF) values ​​(mG) on the three axes x, y, and z.

[0065] FIG. 5 shows an example of a GUI that displays temperature data.

[0066] The GUI 600 shows a time series graph 610 and a table 620. The time series graph 610 and the table 620 display multiple sensor values ​​622 (multiple temperature sensor values) obtained from different sensors 400, synchronized with common time information (horizontal axis of the graph, time column 621). The time information shown in the time column 621 of the table 620 is the time information indicated by the timestamp (step S9).

[0067] The obtained sensor data can be compiled into a database using the information processing device 300 and used for analysis using AI, etc., and can also be used to issue an alarm when a threshold setting is exceeded, or to predict and plan maintenance such as equipment repairs and part replacement.

[0068] Although the embodiments and modified examples of the present technology have been described above, the present technology is not limited to the above-described embodiments, and it goes without saying that various modifications can be made within the scope of the gist of the present technology.
