In the present embodiment, the process of transporting and installing the object 100 to be monitored by the monitoring device 1 will be described with reference to the examples shown in FIGS. 1 and 2. The process includes a process of being packed in a factory or the like as necessary, loaded on a truck 200, and transported to a building 300 installed on the truck 200. The process also includes a process of unloading from the truck 200 by a crane 210, carrying it into the building 300 by hand or by a crane 210 or the like, and then installing the object 100.

The good state of the object 100 means, for example, a state in which the state of the object 100 is guaranteed even by a load applied due to a distribution process or an environment after installation. Further, the defective state of the object 100 means that, for example, the load applied in the distribution process may cause the product housed in the object 100 to be affected by performance deterioration, damage, or the like. This means that the product may be defective as a result.

Etc., and there are obstacles that block the radio. For this reason, adopting a 920 MHz band radio, a so-called sub-giga band radio, which has good propagation due to a long reach of the radio and is excellent in diffractivity, which is easy to wrap around, exerts a peculiar effect in the transport work. ..

The outer body 29 and the outer body 29 are provided.

The sensor unit 11 is provided on each of the objects 100 to be monitored, or is provided on an aggregate of a plurality of objects 100 to be monitored. Therefore, the sensor unit 11 is used as many as the number of objects 100 to be monitored or an aggregate of the objects 100.

The detection sensor 21 includes, for example, an acceleration sensor 31, an inclination sensor 32, a temperature sensor 33, and a humidity sensor 34. The detection sensor 21 is electrically connected to the first control unit 27 via the signal line 98.

The first storage unit 26 is a storage medium called a so-called logger or R-ROM. The first storage unit 26 is configured to be able to store the information detected by the detection sensor 21. Further, the first storage unit 26 is configured to be able to store the first threshold value, the second threshold value, the sampling cycle, the recording cycle, the reporting cycle, and the warning cycle transmitted from the determination device 12 as threshold values.

The first threshold value is a plurality of accelerations arbitrarily set according to the object 100. As a specific example, the first threshold includes four levels of acceleration: trigger level, first warning level, second warning level, and third warning level.

The trigger level of the first threshold value is the acceleration detected by the acceleration sensor 31 and stored in the first storage unit 26. The first warning level to the third warning level are accelerations that are equal to or higher than the trigger level among the information detected by the acceleration sensor 31 and are transmitted to the determination device 12 via the wireless slave unit 22. Further, the first warning level to the third warning level are accelerations at which the applied acceleration may affect the object 100, and are appropriately set according to the object 100. In other words, the first warning level to the third warning level of the first threshold value are standard values for judging the quality of the object 100 based on whether or not an acceleration of a certain value or more is applied to the object 100. It is an acceleration arbitrarily set by the object 100.

The set acceleration is an absolute value. The same acceleration may be set depending on the object 100 when a single or two warning levels are sufficient.

The second threshold value is an inclination angle arbitrarily set according to the object 100. As a specific example, the second threshold includes two tilt angles, a trigger level and a warning level.

The trigger level of the second threshold value is the tilt angle stored in the first storage unit 26 among the information detected by the tilt sensor 32. The warning level is the tilt angle of the information detected by the tilt sensor 32 that is equal to or higher than the trigger level and is transmitted to the determination device 12 via the wireless slave unit 22. The warning level of the second threshold value is an inclination angle at which the object 100 may be affected by the inclination of the object 100. In other words, the first threshold value is a reference value for judging the quality of the object 100 based on whether or not the object 100 is tilted above a certain level, and is an acceleration arbitrarily set by the object 100. ..

The sampling cycle is a cycle in which the acceleration sensor 31 and the tilt sensor 32 detect acceleration and tilt. The sampling period is set as appropriate. For example, the sampling cycle is set by each of the acceleration sensor 31 and the tilt sensor 32.

The recording cycle is a cycle in which information equal to or higher than the trigger level detected by the acceleration sensor 31 and the tilt sensor 32 is stored in the first storage unit 26, and is set by the acceleration sensor 31 and the tilt sensor 32, respectively.

The reporting cycle is a cycle in which information on the acceleration and tilt angle of each warning level of the first threshold value and the second threshold value is transmitted to the determination device 12 among the information of the trigger level or higher stored in the first storage unit 26. For example, the reporting cycle is set by each of the acceleration sensor 31 and the tilt sensor 32.

It is preferable that the comparison between the acceleration and each warning level is performed in common with the comparison between the acceleration and each warning level in the function (2). When the acceleration is equal to or higher than the first warning level, the second warning level, and the third warning level, the first control unit 27 controls the wireless slave unit 22 and transmits the acceleration to the wireless master unit 41 or the repeater 13. ..

Includes a second image pattern 62 for displaying information. In addition, the image pattern is appropriately set in addition to these.

As shown in FIG. 7, the first image pattern 61 corresponds to, for example, the first warning level to the third warning level, “alarm level 1” and “1.5G”, “alarm level 2”, and “3.

As a specific example, the second image pattern 62 shows the numbers of the sensor units 11 as “# 1” and “# 2”, and has an indication of the current load status of each sensor unit 11. Further, the second image pattern 62 has load information such as acceleration, tilt angle, temperature and humidity detected by each sensor unit 11, and displays a list of dates and times when these information are detected.

Further, the second image pattern 62 has a display of a quality judgment of the object 100 based on the information detected by the sensor unit 11. The quality of the object 100 provided with the sensor unit 11 is determined by the colors indicating the identification marks "# 1" and "# 2" of the sensor unit 11. For example, when the acceleration is less than the first threshold value, the object 100 is green as normal, and when the acceleration is equal to or higher than the first warning level of the first threshold value and less than the second warning level, the level is low. Yellow as a warning, orange as a medium level warning if the acceleration is above the second warning level of the first threshold and less than the third warning level, orange if the acceleration is above the third warning level or the tilt angle is the second If it is above the threshold warning level, it is displayed as a high level warning in red. The colors based on the state of the object 100 are stored in advance in the second storage unit 46.

The second control unit 47 is electrically connected to the wireless master unit 41, the display unit 44, the input means 45, and the second storage unit 46 via a signal line 98 or the like.

In the function (4), the second control unit 47 displays information on the display unit 44 based on the image pattern of the display unit 44 stored in the second storage unit 46, and is displayed on the display unit 44. This is a function of setting an input range for inputting an external instruction of the input means 45 based on an image.

For example, the second control unit 47 sets the input range of the input means 45 in the input range of a plurality of threshold values and the range of selecting the sensor unit 11 among the displays of the first image pattern 61 and the second image pattern 62. When the input means 45 is operated, any threshold value in the range is selected, and the display unit 44 and the input means 45 are controlled so that the threshold value can be input.

At this time, when the acceleration is equal to or higher than each warning level, the corresponding color is selected, and the colors of "# 1" and "# 2" which are the identification symbols of the sensor unit 11 of the second image pattern 62 of the display unit 44 are selected. To change. For example, a color corresponding to each warning level is selected, such as green when normal, yellow when the acceleration is equal to or higher than the first warning level of the first threshold value and lower than the second warning level.

The repeater 13 is used when the distance from the wireless master unit 41 to the wireless slave unit 22 is long and the wireless slave unit 22 and the wireless master unit 41 cannot communicate with each other.

Next, an example of a monitoring method in the process of transporting and installing the object 100 using the monitoring device 1 configured in this way, including the process of transporting and installing, will be used with reference to FIGS. 1, 2 and 9. explain.

First, the operator attaches the sensor unit 11 to the object 100 and sets the sensor unit 11 (step ST1). Specifically, the operator operates the determination device 12 to instruct the zero-point correction of the sensor unit 11 attached to the object 100. For example, when an instruction for zero point correction is input by the input means 45, the second control unit 47 assumes that the posture of the sensor unit 11 attached to the object 100 is the reference posture, and the second control unit 47 takes the posture of the sensor unit 11. The tilt angle in is set to 0 °. At the same time, the operator operates the input means 45 to set each threshold value such as the trigger level, the warning level, and the sample cycle of the sensor unit 11 according to the object 100. The second control unit 47 transmits each input threshold value to the sensor unit 11. When the first control unit 27 receives each of the threshold values, the first control unit 27 stores the respective threshold values in the first storage unit 26.

Next, the worker transports the object 100 or installs the object 100 at a predetermined place (step ST2). Here, as shown in FIG. 1, the transport process of the object 100 includes loading the object 100 manufactured in a factory or the like on a truck 200 and transporting the object 100 to a building 300 installed on the truck 200. Further, the process includes unloading from the truck 200 by the crane 210 and carrying it to each floor of the building 300 by hand or by the crane 210 or the like as shown in FIG. Further, as shown in FIG. 2, the installation process includes installing the object 100 carried into each floor of the building 300 at a predetermined position.

When the object 100 is loaded onto the truck 200 in a factory or the like, for example, the supervisor carries the determination device 12. When transporting to the transport destination by the truck 200, for example, the driver of the truck 200 carries the determination device 12. Further, at the transport destination, the supervisor carries the determination device 12 from the unloading of the truck 200 to the installation.

In this way, in the transport and installation process, the determination device 12 can communicate with the sensor unit 11 by carrying the determination device 12 within the range in which the supervisor or the driver can communicate with the wireless slave unit 22 or the repeater 13. It becomes.

The first control unit 27 of the sensor unit 11 determines the load applied to the object 100, in other words, the acceleration and the tilt angle applied to the object 100 in the sampling cycle by the sensors 31 and 32 during transportation or installation. Detect (step ST3). The first control unit 27 compares whether or not the acceleration and the tilt angle are equal to or higher than the trigger level (step ST4).

When the acceleration or tilt angle is equal to or higher than the trigger level (YES in step ST4), the first control unit 27 stores the function (1) in the first storage unit 26 (step ST5). If the acceleration or tilt angle is less than the trigger level (NO in step ST4), the process returns to step ST3, and the first control unit 27 performs the sampling cycle until the acceleration or tilt angle becomes equal to or higher than the trigger level. The load applied to the object 100 is detected.

The first control unit 27 compares whether or not the acceleration or inclination angle equal to or higher than the trigger level is equal to or higher than each warning level (step ST6). When the acceleration or tilt angle equal to or higher than the trigger level is equal to or higher than each warning level (YES in step ST6), the load information of the warning level or higher applied to the object 100 is transmitted to the second control unit 47 (). Step ST7).

Specifically, as the function (2), the first control unit 27 transmits the acceleration to the determination device 12 after the lapse of the reporting cycle of the acceleration or the inclination angle equal to or higher than the warning level. Further, as a function (3), the first control unit 27 has the acceleration of the first warning level and the second warning level or higher at the beginning of the recording cycle and the acceleration of the third warning level or higher during the recording cycle. When the acceleration is detected, all of them are transmitted to the determination device 12.

As a function (6), the second control unit 47 determines whether or not the state of the object 100 in transport and installation is good or bad from the acceleration or inclination angle transmitted from the first control unit 27 in step ST7 (step ST8). Next, the second control unit 47 displays the acceleration or tilt angle transmitted from the first control unit 27 in step ST7 and the result of pass / fail judgment performed in step ST8 as the function (4) and the function (6). It is displayed on 44 (step ST9).

Specifically, as shown in FIG. 8, the second control unit 47 displays the acceleration, tilt angle, temperature, detected date and time, etc. of each sensor unit 11 on the display unit 44, and also displays the identification number of the sensor unit 11. Change the color of the image based on the result of the pass / fail judgment.

A worker such as an observer or a driver confirms the load information and the quality judgment result displayed on the display unit 44 (step ST10), grasps that the load has been applied at the time of transportation or installation, and transports or installs. Continue installation.

If the acceleration or tilt angle is not equal to or higher than the trigger level (NO in step ST4), the display on the display unit 44 does not change as it is on the initial screen. Therefore, the operator confirms the display unit 44 (step ST10). ), It is judged that there is no problem in the transportation or installation of the object 100, and the transportation or installation is continued. Such a process is performed until the transfer and installation are completed (step ST11).

According to the monitoring device 1 configured in this way, the detection information of the load applied to the object 100 detected by the sensor unit 11 can be performed wirelessly with the determination device 12. Further, when the distance from the sensor unit 11 is long, the determination device 12 can communicate with the sensor unit 11 by interposing the repeater 13. Further, by using wireless communication, the monitoring device 1 enables communication between the sensor unit 11 and the determination device 12 even in the building 300 where the infrastructure is not developed.

Further, it is possible to predict damage or the like of the object 100 by a load such as an acceleration or an inclination angle preset as a threshold value without directly checking the object 100, and it is not necessary to open the object 100. Further, when the acceleration and the tilt angle are equal to or higher than each warning level, the sensor unit 11 transmits the information to the determination device 12 before the recording cycle and the reporting cycle have elapsed. Therefore, the monitoring device 1 can easily and instantly determine the quality of the state of the object 100 based on the detected detection information. Therefore, the monitoring device 1 can confirm the state of the object 100 at a position away from the object 100.

Further, the sensor unit 11 has a configuration in which the detection sensor 21, the first storage unit 26, and the first control unit 27 are supplied with power by the first battery 24, and the wireless slave unit 22 is supplied with power by the second battery 25. .. That is, different power supply sources are used depending on the configuration in which the load applied to the object 100 is detected and stored and the configuration in which the detected load information is transmitted to the determination device 12. With this configuration, even if the monitoring device 1 is driven for a long time and the power supply from the second battery 25 to the wireless slave unit 22 is stopped, the detected load information is stored in the first storage unit 26. Is possible. As a result, even when the information cannot be transmitted by the wireless slave unit 22, the load applied to the object 100 can be reliably detected and stored, and the monitoring device 1 has high reliability. Has.

Further, when the acceleration applied to the object 100 is equal to or higher than each warning level which is the first threshold value, the sensor unit 11 transmits the acceleration to the determination device 12 without waiting for the elapse of the reporting cycle. Therefore, it is possible to determine the state of the object 100 in a timely manner. Further, since the state of the object 100 can be determined by the color of the identification mark of each sensor unit 11 displayed on the display unit 44 of the determination device 12, the visibility is good and the situation can be easily grasped. Become.

Further, since the sensor unit 11 limits the number of times of sending acceleration equal to or higher than each warning level in the recording cycle according to each warning level of the first threshold value, it is possible to reduce the power consumption of the second battery 25. Become.

That is, when an acceleration equal to or higher than the highest level of the third warning level is detected, the acceleration is transmitted to the determination device 12 each time it is detected, so that damage to the object 100 can be predicted in a timely manner. It will be possible. Further, with respect to the first warning level and the second warning level, which are lower than the third warning level, only the acceleration detected first during the recording cycle is transmitted, so that the power consumption of the second battery 25 is reduced. Can be done.

In particular, the power consumed by the communication of the wireless slave unit 22 is larger than the power consumed by the storage in the detection sensor 21, the first storage unit 26, and the processing in the first control unit 27. Therefore, the sensor unit 11 can prevent the sensor unit 11 attached to the object 100 from being unable to communicate with the determination device 12 as much as possible before going through the entire process.

Further, by providing the sensor unit 11 on the object 100 and setting each threshold value for each sensor unit 11, it is possible to easily monitor different objects 100. Further, by using the wireless slave unit 22, the wireless master unit 41, and the repeater 13 capable of communicating in a predetermined range, it is possible to simultaneously monitor the work inside and outside the building 300 as long as the communication is possible. ..

Further, in each process, if the sensor unit 11 and the determination device 12 are located at a distance capable of wireless communication, the determination device 12 receives the load applied to the object 100 detected by the sensor unit 11 and causes the object 100 to receive the load. You can judge whether the condition is good or bad. Therefore, for example, the operator only needs to carry the determination device 12 in each process, and has high workability.

Further, the result of the quality judgment of the state of the object 100 judged by the judgment device 12 can be confirmed collectively for the sensor units 11, and each load is equal to or higher than the warning level for each sensor unit 11. In some cases, the situation can be confirmed.

As a result, in all the processes of the distribution process up to delivery, it is possible to continue and stop the transport work based on the quality, and the worker can give a prompt instruction to the carrier.

Further, since the detected load information is associated with the date and time and stored in the first storage unit 26 and transmitted to the determination device 12, the quality of the state of the object 100 for each detection information is determined in the entire process. Become. As a result, by analyzing the data in time series, it is possible to review the inappropriate distribution process in the process, that is, the process that gives a large load to the object 100.

As described above, according to the monitoring device 1 according to the embodiment, the state of the object can be confirmed even at a position away from the object.

The present embodiment is not limited to the above-described embodiment. In the above-described example, the monitoring device 1 has described a configuration in which the quality of the state of the object 100 is determined based on the acceleration and the inclination angle detected by the acceleration sensor 31 and the inclination sensor 32, but the present invention is not limited to this. For example, as a threshold value, a value at which there is a risk of dew condensation on the product is set from the temperature and humidity conditions, and in addition to the judgment based on the acceleration and the inclination angle, the dew condensation is also added to the judgment of the quality of the state of the object 100. You may. Similarly, the configuration may consider damage due to heat. Further, the sensor unit 11 may be configured to include other sensors such as a gyro sensor in addition to the acceleration sensor 31, the tilt sensor 32, the temperature sensor 33 and the humidity sensor 34, and does not have the humidity sensor 34 or the like. It may be a configuration.

Further, the determination device 12 may determine that the state of the object is defective by combining the detection results of the plurality of sensors 31, 32, 33, and 34. In such a determination device 12, for example, the acceleration detected by the acceleration sensor 31 is equal to or higher than the first warning level of the first threshold value, and the tilt angle detected by the tilt sensor 32 is equal to or higher than the warning level of the second threshold value. If this happens, the object 100 may be determined to be defective. Further, for example, both the acceleration sensor 31 and the temperature sensor 33 may determine the quality of the state of the object 100, or other combinations may be used. That is, the monitoring device 1 stores in the first storage unit 26 and the second storage unit 46 a threshold value for making the judgment for each sensor that detects a load that is a target for judging the quality of the state of the object 100, and sets the judgment target. The quality of the state of the object 100 may be determined based on a plurality of threshold values corresponding to the plurality of loads.

Further, in the above-described example, the sensor unit 11, the acceleration sensor 31, the tilt sensor 32, the temperature sensor 33, and the humidity sensor 34 are supplied with power from the first battery 24, and whenever power is supplied, the sensor unit 11 is supplied with power. Although the configuration in which all the sensors are operating has been described, the present invention is not limited to this. For example, the monitoring device 1 has a configuration in which the sensor unit 11 is provided with switching means for allowing the sensors 31, 32, 33, and 34 to operate and stop individually, and detects one of the sensors 31, 32, 33, and 34. The operation and stop of other sensors 31, 32, 33, 34 may be controlled based on the result.

An example of the configuration of the sensor unit 11 that realizes this control will be described. For example, the sensor unit 11 includes a power supply line 99 in which the first battery 24 supplies power to the sensors 31, 32, 33, and 34, respectively, as a switching means for switching the presence or absence of power supply by an open / close signal. The first control unit 27 outputs an open / close signal for controlling the opening / closing of the switch provided on the power supply line 99 described above based on the detection result of any one of the sensors 31, 32, 33, and 34, and receives the signal. Open and close the switch. By such a method of controlling the power supply, the sensor unit 11 operates the other sensors 31, 32, 33, 34 and operates based on the detection result of any one of the sensors 31, 32, 33, 34. Control the stop.

As another method, the sensor unit 11 does not provide a switch as hardware as described above, but further has a control unit for a sensor (not shown) that controls the sensors 31, 32, 33, 34 as a switching means. It may be a configuration. For example, the control unit for such a sensor has a function of stopping sampling of the sensor or lengthening the cycle based on the open / close signal output by the first control unit 27. As described above, the sensor unit 11 may be configured to control the operation and stop of the sensors 31, 32, 33, 34 by software.

As a specific example of the sensor unit 11 that performs this control, the operating time of the tilt sensor 32 is shortened by operating the tilt sensor 32 when the acceleration detected by the acceleration sensor 31 exceeds a certain threshold value. Can be considered. In general, there is a correlation between the detection result by the acceleration sensor 31 and the detection result by the tilt sensor 32, and the tilt sensor 32 does not need to operate all the time. The power saving of the first battery 24 can be saved, and the drive time of the sensor unit 11 can be extended. In particular, when the power consumption of the tilt sensor 32 is larger than that of the acceleration sensor 31, the effect of power saving by shortening the operating time of the tilt sensor 32 becomes high. Further, the first control unit 27 may be provided with a function of controlling the operation and stop of the sensors 31, 32, 33, 34 by such software.

Further, in the above-described example, the tilt angle detected by the tilt sensor 32 has been described as a configuration in which the bird has a level and one warning level as the second threshold value, but the tilt angle is not limited to this, and has a plurality of warning levels. It may be a configuration. Further, when the tilt sensor 32 detects and the reporting cycle has elapsed, all the tilt angles equal to or higher than the warning level may be transmitted to the determination device 12.

Further, in the above-described example, the monitoring device 1 has described a configuration for monitoring the quality of the state of the object 100 in the transportation of the object 100 in the transportation and installation process, but the present invention is not limited to this. For example, it may be configured to be used for transporting the object 100 by a forklift or the like. Further, a sensor unit 11 using a strain gauge or the like is installed in the detection sensor 21 in a tunnel or a bridge, a strain that may be damaged due to aging is set as a threshold value, and the tunnel or the bridge is mounted on a vehicle equipped with the determination device 12. By passing through the tunnel or the bridge, which is the object, the condition of the tunnel or the bridge may be judged.

Further, in the above-described example, the sensor unit 11 describes a configuration in which the first outer shell 28 for storing the detection sensor 21 and the second outer shell 29 are connected by the signal line 98 and the power supply line 99, or this configuration. Not limited to just. For example, the signal line 98 and the power supply line 99 may be coated or bundled with an insulating material such as resin to be integrated. By integrating the signal line 98 and the power supply line 99 in this way, it is possible to reduce the number of lines connecting the first outer shell 28 and the second outer shell 29, and the handling becomes possible. It will be easy.

Further, the sensor unit 11 may be provided with an electrically and physically separable connection portion at a position where the signal line 98 and the power supply line 99 are connected to the first outer body 28 or the second outer body 29. .. As a specific example, the sensor unit 11 divides the signal line 98 and the power supply line 99 that connect the detection sensor 21, the first battery 24, and the first control unit 27 into two, and has a pair of connectors that can be connected to each other. Is provided as a connection part. One of the signal lines 98 and the power supply line 99 is integrally configured as a cable having flexibility and a connector at an end, and the other signal line 98 and the power supply line 99 are one of the outer bodies 28 and 29. It is arranged inside and fixed so that the connector is exposed on one of the outer surfaces of the outer bodies 28 and 29.

The sensor unit 11 having such a configuration can electrically and physically separate the first outer shell 28 and the second outer shell 29 by separating the signal line 98 and the power supply line 99 by the connection portion. It can be handled easily, and each combination can be changed. The change of the combination here means that among a plurality of sensors such as the acceleration sensor 31 and the tilt sensor 32, a plurality of types of first outer bodies 28 in which different sensors are stored are prepared, and an arbitrary first outer body 28 is prepared depending on the intended use. 1 It means that the outer body 28 is selected and the load of the object 100 to be detected is changed.

For example, a first outer body 28 containing the sensors 31, 32, 33, 34 and a first outer body containing the sensors 31, 33, 34, which does not include the tilt sensor 32, are prepared in advance, and depending on the tilt angle. When the object 100 that is not in a bad state is transported and installed, it is possible to operate the first outer shell body that does not include the tilt sensor 32 to be connected to the second outer shell body 29. In this way, the combination of the plurality of sensors can be an arbitrary and easily selectable sensor unit 11.

Further, the sensor unit 11 is provided with a connecting portion as described above, and by arbitrarily selecting a plurality of first outer shells 28 in which different types of sensors are stored and connecting them to the second outer shell 29, the first The combination of the outer shell 28 (detection sensor 21) and the second outer shell 29 may be changed. The sensor unit 11 having such a configuration includes a plurality of control units corresponding to the first control unit 27 and a control switching unit (not shown) in which the second outer body 29 selects and switches one control unit from the plurality of control units. .. In other words, the sensor unit 11 stores a plurality of control programs used for each first outer body 28 as control units (first control unit 27) in the first storage unit 26 or other storage units, and controls the plurality of controls. One control unit is selected from the units by the detection sensor 21 to be used, and the selected control unit is designated as the first control unit 27.

With such a configuration, the sensor unit 11 is selected by including a plurality of control units which are control programs according to the number of detection sensors 21 in which different types of sensors are stored in the first outer body 28. By setting one control unit corresponding to a plurality of control units based on the detection sensor 21 as the first control unit 27, it is possible to operate correctly even when the detection sensor 21 used for the sensor unit 11 is changed.

Further, when the first outer body 28 is changed, the sensor unit 11 is provided with a control switching unit for selecting one of a plurality of control units provided and switching the first control unit 27 to the selected control unit. The first control unit 27 can be correctly switched from the plurality of control units.

The control switching unit here is realized by software, hardware, or a combination thereof, and may be manually switched by the user, or one control automatically corresponding from a plurality of control units depending on the type of the first outer body 28. It may be configured to switch to a unit.

Here, the manual switching by the user means, for example, a function of the determination device 12 that allows the user to select an arbitrary first outer body 28 and a control unit that controls the first outer body 28 from the input means 45. prepare. Then, one is selected from a plurality of control units based on the switching signal input from the input means 45 of the determination device 12 via radio. Further, the switching signal input by the input means 45 here includes information indicating a control unit to be selected. Further, the configuration may be such that switching may be performed by operating a hardware switch included in the second outer shell 29.

Next, automatic switching will be described. For example, the first outer body 28 includes an identification information storage unit in which unique identification information allocated to each of the plurality of first outer body 28s is stored, or the unique identification information is stored in the first storage unit 26. It is remembered. Then, when the first outer body 28 and the second outer body 29 are connected, the identification information is transmitted to the control switching unit, and one control unit associated with the identification information is selected from the plurality of control units. do. Even if the identification information here is not unique information assigned to each of the first outer shell 28, the control switching unit detects the type and combination of the stored sensors and selects the control unit to be selected. You may.
