Description

  The present invention relates to a telephone system, and more particularly to a telephone that includes a main unit connected to a telephone line and a plurality of extension telephones connected to the main unit, and uses a radio telephone as a main unit and a wireless sub unit as an extension telephone. It is about the system.

In a telephone system composed of a main unit connected to a telephone line and a plurality of extension telephones connected to the main unit, a radio telephone may be used as the extension telephone.
This wireless telephone is composed of a parent device and a wireless child device that make a pair, of which the parent device is connected to the main unit, and the wireless child device is connected to the parent device via a wireless line. This type of wireless telephone is called a curled cordless type cordless telephone because there is no curled cord for connecting the handset to the telephone body as compared with a general extension telephone. Usually, a base unit and a wireless slave unit belonging to the same wireless telephone perform wireless communication using the same preset identification information, that is, a system ID, thereby causing interference with the base unit and the wireless slave unit of another wireless telephone. It is the composition which avoids.

In such a telephone system in which a wireless telephone is connected as an extension telephone, the wireless handset of each wireless telephone can be freely carried, and may be erroneously placed on a base unit belonging to another wireless telephone.
In the case of misplacement, the master unit and the wireless slave unit belong to different wireless telephones, so the control of the master unit and the wireless slave unit by the main unit is not linked, and the user is confused. There is. For example, when it is normally placed, if it is picked up by the wireless slave unit from the master unit according to the incoming call display on the master unit, it is regarded as a response operation on the wireless telephone and the wireless slave unit automatically answers the incoming call it can. However, if it is misplaced, even if the wireless slave is picked up, it is regarded as an off-hook in another wireless telephone, and the wireless slave cannot automatically answer the incoming call.

Conventionally, as a method for detecting the mounting state of a wireless slave device relative to the master device, a system ID is obtained by performing wired communication and wireless communication between the master device and the wireless slave device placed on the master device. There has been proposed a method for detecting normal placement by using (see, for example, Patent Document 1).
As shown in FIG. 8, when the wireless slave unit is placed on the master unit and charging is started (step 300), the system ID is transmitted from the master unit to the wireless slave unit by wire communication (step 300). 301) The wireless slave unit compares the system ID from the master unit with the system ID of the wireless slave unit (step 302).

If the two system IDs match (step 302: YES), an ID confirmation indicating that the ID matches can be confirmed by wireless communication from the wireless slave unit to the master unit (step 303).
This confirms that the system ID matches with the wireless slave device placed on the parent device (step 304), and the wireless slave device is normally placed on the original master device. Can be confirmed. Further, when the ID confirmation is not notified from the wireless slave device, it can be determined that the wireless slave device is erroneously placed.
Therefore, it is possible to grasp the erroneous placement state of the wireless slave unit by the main unit by applying such a placement detection method to the radio telephone of the telephone system and notifying the main unit of the detection result of the base unit. it can.

The applicant has not yet found prior art documents related to the present invention by the time of filing other than the prior art documents specified by the prior art document information described in this specification.
JP 2001-038773 A

However, in such a conventional telephone system, there is a problem that the configuration of the master unit and the wireless slave unit becomes complicated when the above-described wireless slave unit placement detection method is adopted.
For example, in the wireless slave device placement detection method as described above, the system ID and the ID confirmation notification are exchanged by performing data communication between the master device and the wireless slave device placed on the master device. Thus, the coincidence of both system IDs is confirmed, and data communication for exchanging these pieces of information between the two is required.

At this time, if the wireless slave unit is misplaced and the two system IDs are different, wireless communication cannot be used. Therefore, wired communication is performed between the two separately from the wireless communication. ing. Therefore, a circuit configuration for performing wired communication is required for the master unit and the wireless slave unit, and a program for these wired communication and wireless communication is required, which complicates the configuration of the wireless telephone.
The present invention is for solving such problems, and provides a telephone system that can grasp the placement relationship between a master unit and a wireless slave unit without complicating the configurations of the master unit and the wireless slave unit. It is an object.

In order to achieve such an object, a telephone system according to the present invention includes a main apparatus connected to a telephone line and a plurality of extension telephones connected to the main apparatus.

Reception timing Depending on whether or not the allowable time difference counting by the monitoring timer, the master machine and the radio personal station is provided with a judging means for judging whether or not the mounting relationship.

Another telephone system according to the present invention includes a main unit connected to a telephone line and a plurality of extension telephones connected to the main unit, and the master unit connected to the main unit as an extension telephone Arbitrary wireless slave unit in a parent unit in a telephone system using a wireless telephone set including a pair of wireless slave units connected to a parent unit via a wireless line, where the wireless slave unit is placed in the parent unit Is provided in the main unit, and is notified from the parent device detection means in response to the detection of the pick-up. A monitoring timer that measures a predetermined allowable time difference is started in response to reception of the detected pick-up information, and the reception timing of the slave unit off-hook detection information notified from the slave unit detection unit in response to detection of off-hook is monitored. Depending on whether or not the allowable time difference counting by Ma, the master machine and the radio personal station is provided with a judging means for judging whether or not the mounting relationship.

The present invention provides a predetermined allowance in response to reception of placement detection information indicating placement of an arbitrary wireless slave unit on the master unit notified from the master unit detection unit by the determination unit provided in the main unit. Start the monitoring timer that counts the time difference, and check whether the reception timing of the slave unit on-hook detection information indicating the on-hook of the wireless slave unit to any master unit notified from the slave unit detection means is during the allowable time difference measurement by the monitoring timer. Depending on whether or not, it is determined whether or not the base unit and the wireless slave unit are placed. Alternatively, a predetermined permissible time difference is counted in response to reception of pick-up detection information notified from the parent device indicating pick-up of an arbitrary wireless slave device from the parent device detection means by the determination means provided in the main device. Starts the monitoring timer, depending on whether the reception timing of the slave unit off-hook detection information indicating the off-hook of the wireless slave unit from any master unit notified from the slave unit detection means is during the allowable time difference measurement by the monitor timer Then, it is determined whether or not the parent device and the wireless slave device are in a placement relationship.
This eliminates the need for wired data communication between the master unit and the wireless slave unit as in the prior art, and complicates the configuration of the master unit and the wireless slave unit as compared with the prior art.
Therefore, it is possible to grasp the normal placement / incorrect placement of the wireless slave device relative to the master device with only a slight change of changing the program of the existing master device, wireless slave device, and main device.

FIG. 3 shows a configuration example of the wireless slave device 40. The wireless slave unit 40 includes a wireless interface unit (hereinafter referred to as a wireless I / F unit) 41, a voice processing unit 42, a battery 43, a charging unit 44, a state detection unit 45, a storage unit 46, a display unit 47, and a key input unit. 48 and a wireless slave unit controller 49 are provided.

It is a functional part, and shows an operation or control operation common to the parent device 30 and the wireless child device 40 performed after the placement of the wireless child device 40 with respect to an arbitrary parent device 30 as a functional unit. It has handset detection means 49A for detecting detection information by the wireless handset.

The state detection unit 45 is realized as a known technique by a general switch such as a hook switch that operates mechanically by placing the wireless slave unit 40 on the base unit 30 or a photo interrupter that operates electrically. There is also an example, and the placement detection unit 38 may use the same switch.
Further, as the state detection unit 45, there is an example in which the electrical connection between the charging terminal 37A and the charging terminal 44A used for the charging operation is detected between the parent device 30 and the wireless slave device 40, and the placement detection unit 38 is also the same. The electrical connection may be detected.

In this case, an amount of electricity that changes due to the electrical connection between the charging terminal 37A and the charging terminal 44A, for example, a current value or a voltage value is taken in from the power feeding unit 37 or the charging unit 44, and wirelessly connected to the parent device 30 according to the change. The presence / absence of the child device 40 may be detected.
When the battery 43 of the wireless slave device 40 is fully charged, the charging power from the master device 30 to the wireless slave device 40 becomes zero. Therefore, for example, when a current of a predetermined value or more is always passed between the charging terminal 37A and the charging terminal 44A, or a predetermined potential is applied, the charging terminal 37A and the charging terminal 44A are in a fully charged state. The presence / absence of electrical connection to may be detected.

FIG. 4 is an explanatory diagram of the placement management information 16A, FIG. 4 (a) is a configuration example of the placement management information, and FIG. 4 (b) is an erroneous placement example of the wireless slave unit.
Detection information detected by the base unit detection means 39A of the base unit 30 is notified to the control unit 15 of the main apparatus 10 by data transmission. Further, the detection information detected by the slave unit detecting means 49A of the wireless slave unit 40 is notified to the master unit control unit 39 of the master unit 30 by wireless communication, and notified to the control unit 15 of the main apparatus 10 in the same manner as described above. Is done.

In the control unit 15 of the main device 10, the determination unit 15 </ b> A determines whether the time difference between the reception timings of the detection information notified from the parent device 30 and the wireless slave device 40 is within a predetermined allowable time difference, and notifies the detection information. Based on the combination of the parent device 30 and the wireless slave device 40 as a base, it is determined to which parent device 30 the wireless slave device 40 is placed, and the corresponding relationship is managed by the placement management information 16A.
At this time, even if the parent device 30 and the wireless child device 40 belong to different wireless telephones 20, the detection information of each of the parent device 30 and the wireless child device 40 is common (same) operation and control operation. If shown, they will be received almost simultaneously. Therefore, the placement relationship between the parent device 30 and the wireless slave device 40 can be determined by comparing the reception timings of these detection information.

In the master unit 30 and the wireless slave unit 40, even if a common operation or control operation is detected, a processing delay occurs to some extent until the detection information is confirmed by the main device 10. For example, when the wired extension transmission path 17 is used for data transmission from the master unit 30 to the main apparatus 10, there is almost no processing delay required for the data transmission.
On the other hand, the data transmission from the wireless slave unit 40 to the main device 10 via the master unit 30 is caused by the wireless protocol because a radio line is interposed between the wireless slave unit 40 and the master unit 30. To some extent, and there is also some processing delay in the detection information transfer processing in the master unit 30. Therefore, a predetermined allowable time difference may be provided for the determination of the reception timing. The allowable time difference may be set for each telephone system as the sensitivity of determination.

  Further, in order to determine the notification source of the detection information, identification information indicating the notification source may be stored in the information. Further, each wireless telephone 20 is connected to the extension I / F unit 13 of the main apparatus 10 via the extension transmission path 17 in a one-to-one relationship, and the extension I / F unit that has received the detection information. Based on the 13 port positions, it may be determined from which radiotelephone 20 the detection information is from.

Individual identification information is assigned in advance to each parent device 30 and the wireless child device 40. In the example of FIG. 4A, the parent device identification information is managed in association with each wireless child device identification information. ing.
For example, as shown in FIG. 4B, when the wireless slave device 40A is erroneously placed on the master device 30B different from the original master device 30A, the placement management information 16A in FIG. “30B” is registered as parent device identification information corresponding to the wireless slave device 40A. Further, in this example, since the wireless slave device 40B is in a neglected state where it is not placed on the shifted master device 30, “Left” is registered as the master device identification information corresponding to the wireless slave device 40B.

Next, the operation of the telephone system according to the first embodiment of the present invention will be described with reference to FIG. FIG. 5 is a sequence diagram showing the operation of the telephone system according to the first embodiment of the present invention.
In the present embodiment, the placement relationship is determined when the wireless handset is placed on a base phone of a different wireless telephone. Hereinafter, a case will be described as an example in which the wireless slave device 40A constituting the wireless telephone 20A paired with the parent device 30A is placed on the parent device 30B of another wireless telephone 20B.

When the wireless slave device 40A is placed at the place where the master device 30B is placed (step 100), the charging terminal 37A of the master device 30B and the charging terminal 44A of the wireless slave device 40A are electrically connected, and the master device 30B. Power is supplied from the power supply unit 37 to the charging unit 44 of the wireless slave device 40A, and charging of the battery 43 of the wireless slave device 40A is started (step 101).
The base unit control unit 39 of the base unit 30B detects the start of the charging operation for any radio slave unit 40 (40A) mounted by the mounting detection unit 38, and the base unit detection means 39A detects the charging operation. The placement of the wireless slave device 40 is detected based on the start (step 102).
Then, base unit control unit 39 transmits detection information related to the placement detected by base unit detection means 39A from extension I / F unit 31 to main apparatus 10 via extension transmission path 17 (step 103).

  The control unit 15 of the main apparatus 10 receives the detection information from the master unit 30B via the extension I / F unit 13, and starts a monitoring timer that measures a predetermined allowable time difference length at the reception timing (confirmation timing). (Step 104), the time difference until the reception timing of the detection information from the wireless slave unit corresponding to the detection information is determined.

On the other hand, the wireless slave device controller 49 of the wireless slave device 40A detects the start of the charging operation of an arbitrary master device 30 (30B) as a slave device on-hook by the state detector 45, and the slave device detection means 49A detects the slave device. A placement on an arbitrary base unit 30 is detected in response to the on-hook (step 105).
Then, the wireless slave device control unit 49 uses the detection information indicating the placement on any parent device 30 detected by the child device detection means 49A as a child device on-hook from the wireless I / F unit 41 via the wireless line. Transmit to 30A (step 106).
The base unit control unit 39 of the base unit 30A receives the slave unit on-hook via the wireless I / F unit 32 and transmits it from the extension I / F unit 31 to the main apparatus 10 via the extension transmission path 17 (step 107). ).

The control unit 15 of the main apparatus 10 receives the slave unit on-hook from the wireless slave unit 40A as detection information via the extension I / F unit 13. At this time, it is assumed that the monitoring timer started in accordance with the detection information from the parent device 30B is operating.
Thereafter, when the monitoring timer started in accordance with the detection information from the parent device 30B ends the operation (step 108), the determination unit 15A operates the monitoring timer started in accordance with the detection information from the parent device 30B. The placement relationship is determined based on the detection information from any wireless slave unit received during step 109 (step 109).

In this case, since the detection information is received from the wireless slave device 40A during the operation of the monitoring timer, the time difference between the reception timings of the detection information received from the master device 30B and the wireless slave device 40A is within the allowable time difference, and the same operation is performed. Alternatively, it is determined that the detection information indicates a control operation, and it is determined that the wireless slave device 40A is placed on the transmission source of the detection information, that is, the parent device 30B. The placement relationship is stored in the placement management information 16 </ b> A of the storage unit 16.
When the detection information is received from the wireless slave device 40A after the monitoring timer expires, the time difference between the reception timings of the detection information received from the master device 30B and the wireless slave device 40A is outside the allowable time difference, and the same operation is performed. Alternatively, it is determined that the detection information does not indicate the control operation, and it is determined that the transmission source of these detection information, that is, the parent device 30B and the wireless slave device 40A are not in a mounting relationship.

  As described above, the base unit detection means 39A detects the placement of an arbitrary wireless slave unit or an operation or control operation performed after the placement, and the slave unit detection unit 49A mounts an arbitrary base unit. Operation or control operation performed after installation or after the placement, and the master unit and the wireless slave unit based on the detection information notified according to the detection by the master unit detection unit 39A and the slave unit detection unit 49A Therefore, it is no longer necessary to perform wired data communication between the master unit and the wireless slave unit as in the conventional case, and the master unit and the wireless slave unit are compared with the conventional unit. This makes it possible to grasp the placement relationship between the master unit and the wireless slave unit without complicating the configuration of.

  In addition, when the determination unit is provided in the main unit and the time difference in the reception timing between the detection information notified from the parent device detection unit 39A and the detection information notified from the child device detection unit 49A is within a predetermined allowable time difference, Since it is determined that the wireless slave device is mounted on the master device, even if various processing delays occur depending on the telephone system for notification processing of each detection information, the master device and the wireless slave device can be configured with a simple configuration. Can be determined.

Next, the operation of the telephone system according to the second embodiment of the present invention will be described with reference to FIG. FIG. 6 is a sequence diagram showing the operation of the telephone system according to the second embodiment of the present invention.
In the first embodiment described above, the case where the placement relationship is determined based on the reception timing of the detection information indicating that the wireless handset is placed on the base unit of a different wireless telephone has been described. In the embodiment, a case will be described in which the placement relationship is determined based on the reception timing of the detection information indicating that the wireless handset is picked up from the state of being placed on the base phone of a different wireless telephone. In the following description, it is assumed that the wireless slave device 40A that forms the wireless telephone 20A in a pair with the parent device 30A is mounted on the parent device 30B of another wireless telephone 20B.

While the wireless slave device 40A is placed on the master device 30B, the charging operation from the master device 30B to the wireless slave device 40A is performed. When the wireless slave device 40A is picked up from the master device 30B, the electrical connection between the charging terminal 37A of the master device 30B and the charging terminal 44A of the wireless slave device 40A is disconnected, and the charging operation is stopped (step 110). .
The base unit control unit 39 of the base unit 30B detects the stop of the charging operation for any radio slave unit 40 (40A) that has been mounted by the mounting detection unit 38, and the base unit detection means 39A performs the charging operation. The pick-up of the wireless slave device 40 is detected in response to the stoppage (step 111).
Then, base unit control unit 39 transmits detection information related to the placement detected by base unit detection means 39A from extension I / F unit 31 to main apparatus 10 via extension transmission path 17 (step 112).

  The control unit 15 of the main apparatus 10 receives the detection information from the master unit 30B via the extension I / F unit 13, and starts a monitoring timer that measures a predetermined allowable time difference length at the reception timing (confirmation timing). (Step 113), the determination of the time difference until the reception timing of the detection information from the wireless slave unit corresponding to the detection information is started.

On the other hand, the wireless slave device controller 49 of the wireless slave device 40A detects the stop of the charging operation of an arbitrary master device 30 (30B) as a slave device off-hook by the state detector 45, and the slave device detection means 49A detects the slave device. In response to the off-hook, pick-up from an arbitrary base unit 30 is detected (step 114).
Then, the wireless slave unit control unit 49 uses the detection information indicating the pick-up from any master unit 30 detected by the slave unit detection means 49A as a slave unit off-hook from the radio I / F unit 41 via the radio line via the radio line. (Step 115).
The base unit control unit 39 of the base unit 30A receives the slave unit off-hook via the wireless I / F unit 32 and transmits it from the extension I / F unit 31 to the main apparatus 10 via the extension transmission path 17 (step 116). ).

The control unit 15 of the main apparatus 10 receives the slave unit off-hook from the wireless slave unit 40A as detection information via the extension I / F unit 13. At this time, it is assumed that the monitoring timer started in accordance with the detection information from the parent device 30B is operating.
After that, when the monitoring timer started according to the detection information from the parent device 30B finishes the operation (step 117), the determination unit 15A operates the monitoring timer started according to the detection information from the parent device 30B. The placement relationship is determined based on the detection information from the arbitrary wireless slave unit received during step S118.

In this case, since the detection information is received from the wireless slave device 40A during the operation of the monitoring timer, the time difference between the reception timings of the detection information received from the master device 30B and the wireless slave device 40A is within the allowable time difference, and the same operation is performed. Alternatively, it is determined that the detection information indicates a control operation, and it is determined that the wireless slave device 40A is placed on the transmission source of the detection information, that is, the parent device 30B. The placement relationship is stored in the placement management information 16 </ b> A of the storage unit 16.
If detection information is received from the wireless slave device 40A after the monitoring timer has expired, the time difference between the reception timings of the detection information received from the master device 30B and the wireless slave device 40A is outside the allowable time difference, and the same operation is performed. Alternatively, it is determined that the detection information does not indicate the control operation, and it is determined that the transmission source of these detection information, that is, the parent device 30B and the wireless slave device 40A are not in a mounting relationship.

In this way, as a specific example of the detection information, the placement detection information indicating the placement of the wireless slave device with respect to the master device or the pick-up detection information indicating the pick-up of the wireless slave device from the master device is used. Notification information for on-hook / off-hook of the wireless handset used in the system can be diverted as detection information, and it is not necessary to transmit / receive new detection information between the base unit and the wireless handset and the main unit, and the operation sequence is reduced. The placement relationship can be determined with almost no change.
As a specific example of the detection information, charging start detection information indicating the start of charging from the parent device to the wireless slave device placed on the parent device, or charging stoppage on the wireless slave device placed on the parent device. The charging stop detection information shown may be used, and detection information related to an operation or control operation common to the parent device and the wireless child device can be easily obtained.

Next, the operation of the telephone system according to the third embodiment of the present invention will be described with reference to FIG. FIG. 7 is a sequence diagram showing the operation of the telephone system according to the third embodiment of the present invention.
In the first and second embodiments described above, the placement relationship is based on the reception timing of detection information indicating the placement of a different wireless telephone on the parent machine or the picking up of the different wireless telephone from the parent machine. However, there are cases where these placements and pick-ups occur at the same time among a plurality of master units and wireless slave units having different placement relationships.

For example, as shown in FIG. 7, when the detection information indicating the placement detection from the base unit 30A is received at time T1 (step 150), the determination unit 15A of the main device 10 is after an allowable time difference tm from the time T1. The monitoring timer A that times up at time T5 is started.
Next, when the detection information indicating the placement detection from the master unit 30B is received at time T2 before the monitoring timer A expires (step 151), the determination unit 15A of the main device 10 similarly performs the time. A monitoring timer B that starts up at time T6 after an allowable time difference tm from T2 is started.

  Thereafter, when the monitoring timer A reaches the time T5, detection information indicating the slave on-hook from the wireless slave units 40B and 40A is received at the previous times T3 and T4 (steps 152 and 153). ), It cannot be determined which detection information indicating the slave unit on-hook corresponds to the detection information from which of the master units 30A and 30B.

In such a case, the determination unit 15A may prioritize a combination with a high probability of occurrence, and may determine that the wireless slave unit is originally placed on the base unit that constitutes the same wireless telephone. In this embodiment, such a determination is not performed, it is determined that it is indeterminate, and the determination is performed again according to the subsequent operation or control operation.
Therefore, for example, in the case where the detection information indicating the placement or the slave unit on-hook becomes unconfirmed, the determination can be made again based on the subsequent pick-up of the wireless slave unit or the detection information indicating the slave unit off-hook.

In each of the above embodiments, as detection information for comparing the reception timing, the placement of the wireless slave unit with respect to the master unit, the picking up of the wireless slave unit from the master unit, the start of the charging operation from the master unit to the wireless slave unit, Although the case where the detection information indicating the end is used individually has been described as an example, the detection information may be mixed.
For example, in addition to the first embodiment described above, the second embodiment is also performed in parallel, and not only when the above device is detected but also when picking up is detected, based on the detection information. The placement relationship may be determined.

By mixing various detection information in this manner, the placement relationship can be determined at more timings without being limited to the timing at which a specific operation or control operation is performed, and the determination accuracy can be improved.
At this time, each detection information stores type information for identifying what operation or control operation the detection information indicates, and the information corresponding to the detection information that activates an arbitrary monitoring timer is stored. When performing position determination, only detection information of the same type information as the detection information may be used as a determination target, and accurate determination can be realized with simple processing.

Further, the detection information is not limited to information indicating the start and end of the charging operation, and any detection information relating to an operation or control operation common to the master unit and the wireless slave unit may be the charging operation and the placement. Information other than the detection information related to the operation can be used in the same manner.
At this time, the common operation or control operation includes not only an operation or control operation that can be detected simultaneously by the parent device and the wireless child device, but also an operation or control operation that can be detected between the parent device and the wireless child device with a certain time difference. Control actions are also included.

In each of the above-described embodiments, the description has been made on the assumption that the on-off and off-hook of the wireless slave unit is detected according to the start and end of the charging operation. There may be a case where detection is performed by means other than presence / absence, for example, by a predetermined switch, or detection is based on presence / absence of electrical contact between charging terminals.
In such a case, detection information indicating the start timing and end timing of the placement may be used regardless of the start and end of charging.

Further, these timings may be the operation timing of the circuit itself, or may be the control timing of the master unit control unit or the wireless slave unit control unit. For example, with respect to the charging operation, there is a case where charging is started without waiting for control by each control unit when the master unit and the wireless slave unit are electrically connected via the charging terminal. In some cases, the battery of the wireless slave unit is in a fully charged state, charging current is not flowing from the master unit to the wireless slave unit, and charging is substantially stopped.
In such a case, for example, a timing at which the start or end of charging is confirmed by each control unit based on a predetermined condition such as a threshold value of charging current, for example, a control timing such as a control for displaying the charging start or end with an LED. Detection information indicating the above may be used.

  Further, in each of the above-described embodiments, the case where the determination unit 15A is provided in the control unit 15 of the main apparatus 10 has been described as an example. However, the present invention is not limited to this, and processing delay due to data transmission of detection information or the like May be provided in a device other than the main device 10 constituting the telephone system, such as a parent device or a wireless child device. Further, as described above, it is not necessary to determine all the placement relationships by one determination means 15A, and only the placement relationship between the parties is determined by the determination means of the parent device or the wireless slave device that has been placed or picked up. It may be determined individually.

  For example, in FIG. 4B, the determination unit 15A provided in the parent device control unit 39 of the parent device 30B obtains detection information from the wireless slave device 40A via the parent device 30A and the main device 10. The detection relationship may be determined by acquiring the detection information by the own device. In addition, the determination unit 15A provided in the wireless slave device control unit 49 of the wireless slave device 40A acquires detection information from the master device 30B via the main device 10 and the master device 30A, and the detection information is acquired by the own device. You may make it determine by acquiring and mounting relationship.

Alternatively, the determination unit 15A provided in the parent device control unit 39 of the parent device 30A obtains detection information from the parent device 30B via the main device 10, and obtains detection information from the wireless child device 40A via a wireless line. May be determined.
When acquiring detection information from another master unit or wireless slave unit via the main unit 10, it is received by the main unit 10 within the monitoring period from the start of the monitoring timer managed by the determination unit 15A to the time-up. What is necessary is just to acquire the detected information.
