Description

The present invention relates to a communication system.

Conventionally, as a technique for detecting an obstacle to an opening / closing body that opens / closes an opening of a building, a seat plate switch that detects the presence of an obstacle in the opening and an obstacle detection state by the seat plate switch are shown. A transmitter that wirelessly transmits an obstacle detection status signal and has a battery as a power source and a receiver that wirelessly receives an obstacle detection status signal from the transmitter have been proposed (a system including a transmitter). For example, see Patent Document 1). In such a system, the voltage of the battery of the transmitter is generally detected at the timing when the seat plate switch is switched or the timing of periodic communication in order to notify whether the battery of the transmitter is exhausted. , It is determined whether or not the battery is exhausted based on the detection result and a predetermined determination condition (specifically, the same determination condition regardless of the state of the opening / closing body at these two timings). When it is determined that the battery is exhausted, the display unit of the transmitter notifies that fact.

However, in the above-mentioned conventional system, as described above, the battery of the transmitter is consumed based on the same determination condition regardless of the state of the open / close body at the timing when the seat plate switch is switched or the timing when periodic communication is performed. Since it was only determined whether or not the transmitter was used, for example, when the situation during periodic communication is such that it is relatively easy to determine that the battery of the transmitter is exhausted, the battery of the transmitter is used. Although the battery is not exhausted, there is a possibility that the display unit of the transmitter frequently notifies the battery, so there is room for improvement from the viewpoint of suppressing false alarms.

The present invention is for solving the above-mentioned problems in the prior art, and an object of the present invention is to provide a communication system capable of suppressing false alarms.

In order to solve the above-mentioned problems and achieve the object, the communication system according to claim 1 is a transmission device attached to an opening / closing body that opens / closes an opening of a building, and is a radio that includes information about the opening / closing body. A communication system including a transmitting device for transmitting a signal, a receiving device provided in the vicinity of the transmitting device, and a receiving device for receiving the radio signal transmitted from the transmitting device, wherein the transmitting device is provided. Includes a battery that serves as a power source for the transmitting device, a detecting means for detecting a state related to the exhaustion of the battery, and a specific means for specifying the state of the opening / closing body in the transmitting device or the receiving device, and the above-mentioned. When the state of the opening / closing body is specified by the specific means as the operating state in which the opening / closing body is operated, based on the detection result of the detection means and whether or not the first determination condition is satisfied. When it is determined whether or not the battery is exhausted and the state of the opening / closing body is specified to be an operation stop state in which the opening / closing body is not operated by the specific means, the detection result of the detection means. A determination means for determining whether or not the battery is exhausted based on whether or not a second determination condition different from the first determination condition is satisfied, and a notification means for notifying the determination result of the determination means. And was provided.

The communication system according to claim 2 is the communication system according to claim 1. When the determination means is specified to be in the operating state by the specific means, the detection means consumes the battery. When the number of detections in which the state related to the above is detected reaches the first number of times, it is determined that the battery is exhausted, assuming that the first determination condition is satisfied, and the operation is stopped by the specific means. When the number of detections reaches the second number, which is larger than the first number, it is determined that the battery is exhausted, assuming that the second determination condition is satisfied.

The communication system according to claim 3 is the communication system according to claim 2, wherein the determination means is specified by the specific means as either the operation state or the operation stop state, and the operation stop state is specified. When the number of detections has not reached either the first number or the second number, and the specific means specifies that the operation state or the operation stop state is the other, the detection number is determined to be either the operation state or the operation stop state. Either one of the first judgment condition or the second judgment condition, which is the judgment condition immediately before the specific, is changed to either the first judgment condition or the second judgment condition, and the changed judgment condition is adopted. Based on this, it is determined whether or not the battery is exhausted.

The communication system according to claim 4 is the communication system according to any one of claims 1 to 3, wherein the operating state is a state in which the seat plate switch attached to the opening / closing body is switched. The operation stop state is a state in which periodic communication of the transmission device is being performed.

The communication system according to claim 5 is the communication system according to claim 4, wherein when the transmitting device or the receiving device detects a state related to battery consumption by the detecting means, the periodic communication is performed. A change means for changing the implementation interval of the above was provided.

The communication system according to claim 6 is the communication system according to claim 5, wherein the changing means detects a state related to battery consumption by the detecting means after the execution interval of the periodic communication is changed. If not, the execution interval of the periodic communication is returned to the execution interval before the change.

According to the communication system according to claim 1, the transmitting device or the receiving device has a specific means for specifying the state of the open / close body, and when the specific means specifies that the state is in operation, the detection result of the detection means. And, based on whether or not the first determination condition is satisfied, it is determined whether or not the battery of the transmitting device is exhausted, and when it is specified by the specific means that the operation is stopped, the detection means is detected. Since the opening / closing body is provided with a determination means for determining whether or not the battery is exhausted based on the result and whether or not the second determination condition is satisfied, and a notification means for notifying the determination result of the determination means. It is possible to determine whether or not the battery of the transmitting device is exhausted based on different determination conditions according to the state of the above and notify the determination result. Therefore, as compared with the case where the presence or absence of battery consumption of the transmitting device is determined under the same determination conditions regardless of the state of the opening / closing body, the above determination result can be notified according to the state of the opening / closing body, and the above determination can be performed. It is possible to suppress false notification of the result.

According to the communication system according to claim 2, when the determination means is specified to be in the operating state by the specific means and the number of detections reaches the first number, the first determination condition is satisfied. When it is determined that the battery is exhausted and the operation is stopped by the specific means, and the number of detections reaches the second number, the battery is regarded as satisfying the second determination condition. Since it is determined that the battery is exhausted, it is possible to determine whether or not the battery of the transmitting device is consumed based on the number of detections different depending on the state of the open / close body, and the determination accuracy can be improved.

According to the communication system according to claim 3, the determination means is specified by the specific means as either an operating state or an operating stopped state, and the number of detections is either the first or the second. If one of them is not reached and it is specified by the specific means to be either the operating state or the stopped operation state, the first judgment condition or the second judgment condition which is the judgment condition immediately before the specific is specified. Since either one of the above is changed to either the first judgment condition or the second judgment condition and it is judged whether or not the battery is exhausted based on the changed judgment condition, the number of detections is the first time or the number of times of detection. Compared to the case where it is judged whether or not the battery of the transmitter is exhausted without changing the judgment condition when the state of the opening / closing body is changed when one of the second times is not reached, the state of the opening / closing body is changed. It is possible to determine whether or not the battery of the transmitting device is exhausted according to the situation, and the determination accuracy can be further improved.

According to the communication system according to claim 4, the operating state is a state in which the seat plate switch attached to the open / close body is switched, and the operation stop state is a state in which periodic communication of the transmitting device is performed. Therefore, it is possible to determine whether or not the battery of the transmitter is exhausted based on different determination conditions depending on the state in which the seat plate switch is switched and the state in which periodic communication is being performed, and notify the determination result. It is possible to suppress false alarm of the above determination result in the state where the seat plate switch is switched and the periodic communication is performed.

According to the communication system according to claim 5, since the transmitting device or the receiving device is provided with a changing means for changing the execution interval of periodic communication when a state related to battery consumption is detected by the detecting means. It is possible to change the execution interval of periodic communication performed after the state related to battery consumption is detected by the detection means, and it is possible to perform periodic communication according to the battery status of the transmitting device.

According to the communication system according to claim 6, when the changing means does not detect the state related to battery consumption by the detecting means after the periodic communication execution interval is changed, the periodic communication execution interval is changed. Since it returns to the previous execution interval, the execution interval of the periodic communication changed by the changing means can be automatically returned to the execution interval before the change, and the trouble of returning the execution interval of the periodic communication can be omitted.

The term "intermittent transmission by the transmission device 120" means that the first radio signal is intermittently transmitted a plurality of times from the arrival of the transmission timing of the communication process described later to the elapse of a predetermined time (note that the transmission device 120 intermittently transmits the first radio signal). The same applies to the intermittent transmission of the second frequency described later).

Further, the "second frequency" means a frequency different from the first frequency and is not obliged to perform carrier sense. In the embodiment, the second frequency is a frequency of a frequency band that is close to the frequency band to which the first frequency belongs and is capable of intermittent transmission by the transmission device 120, and is, for example, a frequency band for a specific low power radio station. Corresponds to a frequency or the like having a frequency of 928.15 MHz or more and 929.65 MHz or less. However, the present invention is not limited to this, and may be, for example, a frequency in another frequency band (for example, a frequency in a frequency band capable of continuous transmission by the transmitting device 120).

By setting the first frequency and the second frequency as described above, for example, it becomes relatively easy to simplify the configuration of the transmission device 120 (specifically, the configuration of the transmission unit 124a or the control unit 128), so that transmission is possible. The manufacturing cost of the device 120 can be reduced.

Further, the method of transmitting the first radio signal by the transmission unit 124a using the first frequency and the second frequency is arbitrary, but in the embodiment, the transmission time of the first radio signal when the first frequency is used is arbitrary. (Specifically, the transmission time when intermittently transmitting) is the same as the transmission time of the first radio signal when the second frequency is used, and the radio strength of the first radio signal when the first frequency is used. Is transmitted by making it the same as the radio field strength of the first radio signal when the second frequency is used (note that the first frequency and the second frequency by the transmitting unit 135b of the receiving device 130 described later will be described later. The same applies to the method of transmitting the second radio signal). As a result, the transmission time (or radio wave strength) of the first radio signal when using the first frequency is different from the transmission time (or radio wave strength) of the first radio signal when using the second frequency. Since the configuration of the transmission device 120 (specifically, the configuration of the transmission unit 124a or the control unit 128, etc.) can be easily simplified, the manufacturing cost of the transmission device 120 can be reduced.

Can be transmitted on the first frequency or the second frequency.

(Communication processing)
Next, the communication processing executed by the obstacle detection system 100 configured in this way will be described. In the following description, in the description of each process shown in FIGS. 6 and 7, the step is abbreviated as “S”. The communication process is generally a process for communicating between the transmitting device 120 and the receiving device 130. Further, the timing for executing this communication process is arbitrary, but in the embodiment, the power is turned on to the switch 40, the automatic closing device 50, the operating device 60, the control device 80, the transmitting device 120, and the receiving device 130. It is assumed that it is started after that.

When the communication process is started, in order to prepare for the communication process, the control unit 128 of the transmission device 120 performs the processing of the SA1 shown in FIG. 6, and the control unit 138 of the reception device 130 is shown in FIG. 7. Performs SB1 processing.

First, as shown in FIG. 6, the control unit 128 of the transmission device 120 executes the preparation process in SA1. The processing content of this preparation processing is arbitrary, but in the embodiment, the first transmission setting processing, the change processing, and the first reception setting processing are performed. Of these, the "first transmission setting process" is a process for setting a plurality of first frequencies and second frequencies used when the transmission device 120 transmits the first radio signal. Further, the "change process" is a process of changing the transmission order of a plurality of first frequencies set in the first transmission setting process. Further, the "first reception setting process" is a process of setting two first frequencies and second frequencies to be monitored when the transmission device 120 receives the second radio signal.

Specifically, regarding the first transmission setting process, when any one of the channel information stored in the transmission side frequency table 129a is selected via the operation unit 122 of the transmission device 120, the transmission device 120 The control unit 128 of is the first first frequency information corresponding to the selected channel information from the first first frequency information, the second first frequency information, and the second frequency information stored in the transmitting side frequency table 129a. The first frequency information, the second first frequency information, and the second frequency information are extracted, and the frequencies of the extracted information are set as the two first frequency and the second frequency to be set. This makes it possible to set the first frequency and the second frequency according to the surrounding environment.

Regarding the change processing, if a predetermined operation is not accepted via the operation unit 122 of the transmission device 120 after the first transmission setting process is performed, the first change unit 128b of the transmission device 120 may be plural. The transmission order when transmitting the first radio signal using the first frequency of is not changed (that is, the first frequency used for transmitting the first first radio signal = the first frequency of the first first frequency information). 1st frequency used for transmission of the 2nd 1st radio signal = 1st frequency of the 2nd 1st frequency information). On the other hand, when the predetermined operation is accepted via the operation unit 122 of the transmission device 120 after the first transmission setting process is performed (note that the predetermined operation is accepted at a timing other than the SA1 process). The first changing unit 128b of the transmitting device 120 changes the transmission order (that is, the first frequency used for transmitting the first first radio signal = the first of the second first frequency information). Set to the frequency, and set the first frequency used for transmitting the second first radio signal = the first frequency of the first first frequency information). As a result, the transmission order when transmitting the first radio signal using the plurality of first frequencies can be changed, and it becomes easy to transmit the first radio signal according to the situation. For example, assuming that the transmission device 120 of the switchgear 1 and the transmission device 120 of another switchgear 1 adjacent to the switchgear 1 have a first frequency corresponding to the same channel set in the first transmission setting process. However, interference of radio signals can be avoided by changing the transmission order of the first frequency by the change process.

Further, the first reception setting process is set as the two first frequency and the second frequency to be set by the same process as the first transmission setting process. This makes it possible to easily set the first frequency or the second frequency to be monitored when receiving the second radio signal. In the embodiment, the first frequency and the second frequency set in the first transmission setting process are automatically set as the first frequency and the second frequency to be set in the first reception setting process. (That is, the setting of the first reception setting process and the setting of the first transmission setting process are performed together), but the present invention is not limited to this, and for example, the setting of the first reception setting process and the setting of the first transmission setting process. May be performed individually (the same applies to the setting of the second transmission setting process and the second reception setting process described later).

Further, as shown in FIG. 7, the control unit 138 of the receiving device 130 executes the preparation process in SB1 at substantially the same timing as the start timing of the process of SA1. The processing content of this preparation processing is arbitrary, but in the embodiment, the second reception setting processing and the second transmission setting processing are performed. Of these, the "second reception setting process" is a process of setting the first frequency and the second frequency to be monitored when the receiving device 130 receives the first radio signal. Further, the "second transmission setting process" is a process of setting the first frequency and the second frequency used when the receiving device 130 transmits the second radio signal.

Specifically, regarding the second reception setting process, when any one of the channel information stored in the reception side frequency table 139a is selected via the operation unit 133 of the reception device 130, the reception device 130 The control unit 138 of is selected from the first frequency information, the second first frequency information, and the second frequency information stored in the receiving side frequency table 139a (specifically, the control unit 138). The first first frequency information, the second first frequency information, and the second frequency information corresponding to (the same channel information as the channel information selected in the first transmission setting process) are extracted, and the frequency of the extracted information is extracted. Is set as the two first and second frequencies to be set. This makes it possible to easily set the first frequency and the second frequency to be monitored when receiving the first radio signal.

Further, the second transmission setting process is set as the two first frequency and the second frequency to be set by the same process as the second reception setting process. This makes it possible to set the first frequency and the second frequency according to the surrounding environment.

Returning to FIG. 6, next, in order to transmit the first radio signal from the transmission device 120, the control unit 128 of the transmission device 120 performs the processing of SA2 to SA10 shown in FIG.

First, as shown in FIG. 6, in SA2, the specifying unit 128c of the transmitting device 120 specifies the state of the opening / closing body 30.

The method of specifying the state of the opening / closing body 30 is arbitrary, but is as follows, for example. That is, when the state of the opening / closing body 30 is specified as the operating state, whether or not the state in which the input of the obstacle detection state signal is not accepted from the seat plate switch 110 via the input unit 121 is switched to the accepted state. (Or whether or not the input of the obstacle detection status signal has been switched from the accepted state to the unaccepted state). When the above switching is performed, the seat plate switch 110 is specified as an operating state because it is in a switched state, but when the switching is not performed, it is not specified as an operating state.

Further, when the state of the opening / closing body 30 is specified as the operation stop state, it is specified based on whether or not periodic communication is set in SA3 described later. When the periodic communication is set, it is specified as an operation stop state because the periodic communication is being performed, but when the periodic communication is not set, it is not specified as an operation stop state. ..

In SA3, the control unit 128 of the transmission device 120 determines whether or not the state of the opening / closing body 30 specified by SA2 is the operation stop state. Then, the control unit 128 of the transmission device 120 shifts to SA4 when it is determined that the operation is stopped (SA3, Yes), and when it is determined that the operation is not stopped (SA3, No). Moves to SA5.

In SA4, the control unit 128 of the transmission device 120 sets the communication method to periodic communication (or maintains the setting if periodic communication has already been set), and shifts to SA6.

In SA5, the control unit 128 of the transmission device 120 sets the communication method to normal communication (or maintains the setting if normal communication has already been set), and shifts to SA6. Here, "normal communication" means transmitting the first radio signal to the receiving device 130 at the timing specified by the SA2 as the operating state.

In the SA6, the control unit 128 of the transmission device 120 determines whether or not the timing for transmitting the first radio signal (hereinafter, referred to as “transmission timing”) has arrived.

The method for determining whether or not the transmission timing has arrived is arbitrary, but is as follows, for example. That is, when the communication method is set to periodic communication in SA4, it is determined whether or not the periodic communication execution interval has elapsed since the setting, and the periodic communication execution interval has elapsed. In this case, it is determined that the transmission timing has arrived, and if the periodic communication execution interval has not elapsed, it is determined that the transmission timing has not arrived. Further, when the communication method is set to normal communication in SA5, it is determined in SA2 whether or not it is specified as an operating state, and when it is specified as an operating state, the transmission timing has arrived. If it is not specified as an operating state, it is determined that the transmission timing has not arrived. Then, the control unit 128 of the transmission device 120 shifts to SA2 when it is determined that the transmission timing has not arrived (SA6, No), and when it is determined that the transmission timing has arrived (SA6, No). Yes) will shift to SA7.

In the SA7, the control unit 128 of the transmission device 120 provides information (hereinafter, referred to as “battery state information”) indicating the state of the battery 126 (specifically, the state related to the consumption or non-consumption of the battery 126) from the detection unit 127. get.

In the SA8, the first determination unit 128a of the transmission device 120 determines whether or not the first transmission is possible. The method for determining whether or not the first transmission is possible is arbitrary, but for example, any frequency among the plurality of first frequencies set in the first transmission setting process of SA1 is used. 1 When an attempt is made to transmit a radio signal and it is detected by the carrier sense performed at the time of the transmission that there is no carrier, it is determined that the first transmission is possible. On the other hand, no matter which of the plurality of first frequencies set in the first transmission setting process of SA1 is used to transmit the first radio signal, there is a carrier due to the carrier sense performed at the time of the transmission. If it is detected, it is determined that the first transmission is not possible. Regarding the above-mentioned determination, the two first frequencies set in the change processing of SA1 shall be sequentially performed based on the transmission order of the change processing. Then, the first determination unit 128a of the transmission device 120 shifts to SA9 when it is determined that the first transmission is possible (SA8, Yes), and when it is determined that the first transmission is not possible (SA8). , No) shifts to SA10.

In the SA9, the control unit 128 of the transmission device 120 causes the transmission unit 124a to transmit the first radio signal using the first frequency, and then shifts to the SA11. Specifically, the first radio signal is intermittently transmitted a plurality of times (so-called intermittent transmission) from the arrival of the transmission timing of SA6 to the reception of the second radio signal by SA11 described later (note that it will be described later). The same applies to the processing of SA10.

Here, regarding the first frequency used for transmitting the first radio signal, it is detected by the carrier sense in SA8 that there is no carrier among the plurality of first frequencies set in the first transmission setting process of SA1. The first frequency is used. Even if none of the plurality of first frequencies has a carrier, as described above, the determination of SA8 is sequentially performed based on the transmission order set in the change process of SA1, and the first transmission possible status. Since the first frequency at the time when it is determined to be is used, as a result, the first frequency having an earlier transmission order is preferentially used. Further, the information included in the first radio signal includes, for example, communication type information, battery status information acquired by SA7, seat plate switch status information, communication target identification information, and the like (note that SA10 described later). The same applies to the information contained in the first radio signal of.). Of these, the "communication type information" means information indicating the type of communication (for example, normal communication, periodic communication, response communication, etc.). Further, the "seat plate switch state information" is information indicating the state of the seat plate switch 110 at the time of processing the SA2, and is, for example, information indicating a state in which an obstacle is not detected (hereinafter, "obstacle non-detection"). It is a concept that includes "state information") and obstacle detection state information. Further, the "communication target identification information" is information for uniquely identifying the communication target, and in the embodiment, it is assumed that the information is stored in advance in the storage unit 129 of the transmission device 120.

In the SA10, the control unit 128 of the transmission device 120 causes the transmission unit 124a to transmit the first radio signal using the second frequency (specifically, the second frequency set in the first transmission setting process of the SA1). After that, it shifts to SA11.

The surrounding communication environment is compared with the case where the first radio signal is transmitted using only the frequencies for which carrier sense is obliged by such processing from SA2 to SA10 (particularly, processing from SA8 to SA10). The first radio signal can be transmitted quickly and reliably without being influenced by the above, and the reliability of communication can be improved. In particular, in the processing of SA10, after it is confirmed by carrier sense regarding a plurality of first frequencies that the carrier is present, the first radio signal can be transmitted using the second frequency, and communication is performed while suppressing interference of the radio signals. Can increase the reliability of. Further, the transmission device 120 can quickly and surely transmit the first radio signal including the obstacle detection state information without being influenced by the surrounding communication environment, and can effectively notify the presence or absence of an obstacle, for example.

The method of transmitting the first radio signal in the SA9 and SA10 is arbitrary, but for example, when the SA8 determines that the first transmission is possible, the transmission unit 124a determines that the first radio signal can be transmitted immediately after the determination. When the first radio signal is transmitted using one frequency and the SA8 determines that the first transmission is not possible, the transmission unit 124a immediately transmits the first radio signal using the second frequency immediately after the determination. It may be transmitted (the same applies to the processing of SB12 and SB13 described later). As a result, the first radio signal can be quickly transmitted even when the first radio signal is transmitted using the first frequency and when the first radio signal is transmitted using the second frequency (particularly). In the embodiment, the timing of transmitting the first radio signal using the first frequency having the second transmission order in SA9 and the timing of transmitting the first radio signal using the second frequency in SA10 are set. It can be made almost the same), and the reliability of communication can be further improved. However, the present invention is not limited to this, and for example, when the SA8 determines that the first transmission is possible, the first radio signal is transmitted using the first frequency after a predetermined time has elapsed from the determination. When it is determined by SA8 that the first transmission is not possible, the first radio signal may be transmitted using the second frequency after a predetermined time has elapsed from the determination (note that SB12 and SB13 described later). The same applies to the processing of).

Next, in order to notify that the battery 126 of the transmitting device 120 is exhausted, the control unit 138 of the receiving device 130 processes SB2 to SB10 shown in FIG. 7.

First, as shown in FIG. 7, in SB2, the control unit 138 of the receiving device 130 determines whether or not the first radio signal transmitted by the receiving unit 135a has been received by the SA9 or SA10. The method for determining whether or not the first radio signal has been received is arbitrary, but for example, it is first transmitted on the two first and second frequencies set in the second reception setting process of SB1. Whether or not the first radio signal can be received is sequentially and repeatedly monitored. Next, when the first radio signal can be received, the communication target identification information included in the first radio signal matches the communication target identification information stored in advance in the storage unit 139 of the receiving device 130. Judge whether or not. Here, if these two communication target identification information match, it is determined that the first radio signal has been received, and if these two communication target identification information do not match, or if the first radio signal cannot be received, it is determined. It is determined that the first radio signal has not been received. Then, the control unit 138 of the receiving device 130 waits until the first radio signal is received (SB2, No), and when the first radio signal is received (SB2, Yes), it shifts to SB3.

In SB3, the control unit 138 of the receiving device 130 determines whether or not the detection unit 127 has detected the state related to the consumption of the battery 126 of the transmitting device 120. Specifically, it is determined whether or not the battery state information included in the first radio signal received by SB2 is the information indicating the state related to the consumption of the battery 126, and the information indicating the state related to the consumption of the battery 126. In the case of It is determined that the state related to the consumption of the battery 126 has not been detected. Then, when it is determined by the detection unit 127 that the state related to the consumption of the battery 126 of the transmission device 120 is detected (SB3, Yes), the control unit 138 of the reception device 130 shifts to the SB4 and the detection unit When it is determined in 127 that the state related to the consumption of the battery 126 of the transmission device 120 is not detected (SB3, No), the process proceeds to SB5.

In SB4, the control unit 138 of the receiving device 130 updates the number of times (hereinafter, referred to as “detection number”) that the detection unit 127 of the transmitting device 120 detects the state related to the consumption of the battery 126 of the transmitting device 120. After that, it shifts to SB6. Specifically, since the battery status information included in the first radio signal received by the SB2 is information indicating the state related to the consumption of the battery 126 of the transmission device 120, 1 is added to the number of detections before the processing of the SB4. Update the number of times of detection as the number of detections to be updated.

In SB5, the control unit 138 of the receiving device 130 updates the number of detections, and then shifts to SB7. Specifically, since the battery status information included in the first radio signal received by the SB2 is information indicating the non-consumable status of the battery 126 of the transmission device 120, the number of detections is set to a default value (for example, a zero value). ). However, the present invention is not limited to this, and for example, it is not necessary to update the number of detections (that is, the number of detections before the processing of SB5 is maintained).

In SB6, the second change unit 138c of the receiving device 130 changes the execution interval of the periodic communication, and then shifts to SB8. The method of changing the execution interval of this periodic communication is arbitrary, but for example, the execution interval to be changed (hereinafter referred to as “second execution interval”) is the execution interval before the processing of SB6 and is stored in advance in the storage unit 139. It may be changed to be shorter (or longer) than the execution interval (hereinafter referred to as "first implementation interval") stored in. As an example, when the first implementation interval = 24 hours, the second implementation interval may be changed to 12 hours in order to make the time zone different. However, if the first implementation interval has already been changed in the SB6 performed before that, the processing of the SB6 may be omitted, or the second implementation interval may be shorter (or shorter than the first implementation interval). It may be changed to be longer). As a result, it is possible to change the execution interval of the periodic communication performed after the detection unit 127 detects the state related to the consumption of the battery 126 of the transmission device 120, and the periodic communication is performed according to the state of the battery 126 of the transmission device 120. Is possible.

In SB7, the second changing unit 138c of the receiving device 130 periodically performs a periodic communication when the detection unit 127 does not detect the state related to the consumption of the battery 126 of the transmitting device 120 after the execution interval of the periodic communication is changed in SB6. The communication execution interval is returned to the execution interval before the change, and then the operation shifts to SB8. The method of returning the execution interval of this periodic communication is arbitrary, but for example, the second execution interval may be returned to the first execution interval. However, if the execution interval before the processing of SB7 has already been returned in the SB7 performed before that, or if the execution interval of the periodic communication has not been changed in the SB6 before that, the processing of the SB7 is performed. It may be omitted. As a result, the execution interval of the periodic communication changed by the second change unit 138c can be automatically returned to the execution interval before the change, and the trouble of returning the execution interval of the periodic communication can be omitted.

In the SB8, the battery consumption determination unit 138a of the receiving device 130 is used when the communication type information included in the first radio signal received by the SB2 is information indicating normal communication (that is, in the specific unit 128c of the transmitting device 120). When it is specified to be in the operating state), it is based on the number of detections updated by SB4 or SB5 (that is, the detection result of the detection unit 127 of the transmission device 120) and whether or not the first determination condition is satisfied. Then, it is determined whether or not the battery 126 of the transmission device 120 is exhausted. Further, when the communication type information included in the first radio signal received by SB2 is information indicating periodic communication (that is, when it is specified by the specific unit 128c of the transmission device 120 that the operation is stopped). It is determined whether or not the battery 126 of the transmission device 120 is exhausted based on the number of detections updated by SB4 or SB5 and whether or not the second determination condition is satisfied. Then, when it is determined that the battery 126 of the transmitting device 120 is exhausted (SB8, Yes), the battery consumption determination unit 138a of the receiving device 130 shifts to the SB9, and the battery 126 of the transmitting device 120 is consumed. If it is determined that the battery is not present (SB8, No), the process proceeds to SB10.

Here, the method of determining whether or not the battery 126 of the transmission device 120 is exhausted is arbitrary, but in the embodiment, it is as follows. The first determination condition used in this determination method will be described as the number of detections updated by SB4 or SB5 reaches the first number of times (for example, one or more times). Further, regarding the second determination condition used in this determination method, it is described that the number of detections updated by SB4 or SB5 reaches the second number (for example, two or more times) which is larger than the first number. do.

That is, when the communication type information is information indicating normal communication and the number of detections updated by SB4 or SB5 does not reach the first number, it is assumed that the first determination condition is not satisfied. If it is determined that the battery 126 of the transmission device 120 is not exhausted and the number of detections updated by SB4 or SB5 has reached the first number, it is assumed that the first determination condition is satisfied, and the transmission device 120 It is determined that the battery 126 is exhausted. Further, when the communication type information is information indicating periodic communication and the number of detections updated by SB4 or SB5 does not reach the second number, it is assumed that the second determination condition is not satisfied. If it is determined that the battery 126 of the transmission device 120 is not exhausted and the number of detections updated by SB4 or SB5 has reached the second number, the second determination condition is satisfied and the transmission device 120 is used. It is determined that the battery 126 is exhausted. Thereby, it is possible to determine whether or not the battery 126 of the transmission device 120 is consumed based on the number of detections different depending on the state of the open / close body 30, and the determination accuracy can be improved. In the embodiment, it is determined when the number of detections reaches the first number in the determination when the communication type information is information indicating normal communication, or when the communication type information is information indicating periodic communication. When the number of detections reaches the second number, in the SB3 performed thereafter, if the battery status information is information indicating a state related to the non-depletion of the battery 126 of the transmission device 120, the number of detections is set in the SB5. Although the default value is updated, when the battery status information is information indicating the state related to the consumption of the battery 126 of the transmission device 120, the number of detections is maintained in SB4. As a result, if the detection unit 127 continuously detects the state related to the consumption of the battery 126 of the transmission device 120 after the SB8 determines that the battery 126 of the transmission device 120 is exhausted, the relevant state is concerned. Since the determination can be continued, the processing of SB9 can be surely continued.

Further, it may be determined whether or not the battery 126 of the transmission device 120 is consumed by the processing content other than the processing content described above. For example, when the communication type information is information indicating normal communication and the number of detections updated by SB4 or SB5 has not reached the first number, the first received by SB4 or SB5. When the communication type information included in the wireless signal is information indicating periodic communication, the first judgment condition, which is the judgment condition immediately before the specific, is changed to the second judgment condition, and the changed second judgment condition is used. Based on this, it may be determined whether or not the battery 126 of the transmission device 120 is exhausted (note that the communication type information is information indicating periodic communication, and the detection updated by SB4 or SB5 is performed. The same shall apply when the number of times has not reached the second number). In this case, the number of detections after the determination condition is changed may be updated to the default value, or the number of detections before the determination condition is changed may be carried over. As a result, as compared with the case where it is determined whether or not the battery 126 of the transmission device 120 is exhausted without changing the determination condition when the state of the opening / closing body 30 is changed when the number of detections has not reached the first number of times. It is possible to determine whether or not the battery 126 of the transmission device 120 is consumed according to the state of the opening / closing body 30, and the determination accuracy can be further improved.

In SB9, the notification unit 138b of the receiving device 130 executes the first transfer processing, and then shifts to SB11. Here, the "first transfer process" is information indicating that the battery 126 of the transmission device 120 is exhausted (hereinafter referred to as "battery consumption information") or a first radio signal received by the SB2. It is a process for notifying the information contained in.

The processing content of this first transfer processing is arbitrary, but for example, the output unit 132 of the receiving device 130 can use the battery consumption information and the seat plate switch status information included in the first radio signal received by the SB2. The including signal (hereinafter, referred to as "first transfer signal") may be output to the control device 80. Alternatively, the display unit 134 of the receiving device 130 may display the battery consumption information. Alternatively, these may be combined.

The specific control content of the control device 80 that has received the first transfer signal is arbitrary, but for example, control for notifying the user that the battery 126 of the transmission device 120 is exhausted. Therefore, control different from the normal control of the control device 80 may be performed. As an example, regarding the opening / closing movement of the opening / closing body 30, the opening / closing movement of the opening / closing body 30 (specifically, the electric closing movement or the opening movement) is performed only while the input of the operation signal is received from the operation device 60. It may be done (so-called "control of opening / closing movement of the opening / closing body 30 by push-off operation"). Further, as for the display of the display unit 66 of the operation device 60, the battery consumption information may be displayed. Further, control may be performed based on the presence or absence of an obstacle. As an example, when the seat plate switch state information is the obstacle detection state information, a predetermined timing (for example, an operation signal is input from the operation device 60). The opening / closing movement of the opening / closing body 30 may be restricted until the timing at which is received, the timing at which the first radio signal including the obstacle non-detection state information is received at SB2 performed after the processing of SB9, etc. arrives. (For example, stopping the closing movement of the opening / closing body 30 due to its own weight, etc.).

In the SB10, the notification unit 138b of the receiving device 130 executes the second transfer processing, and then shifts to the SB11. Here, the "second transfer process" is information indicating that the battery 126 of the transmission device 120 is not consumed (hereinafter referred to as "battery non-consumable information") or the first radio received by SB2. This is a process for notifying the information contained in the signal.

Further, the processing content of the second transfer processing is arbitrary, but for example, the seat plate switch included in the battery non-consumable information and the first radio signal received by the SB2 by the output unit 132 of the receiving device 130. A signal including the state information (hereinafter, referred to as “second transfer signal”) may be output to the control device 80. Alternatively, the display unit 134 of the receiving device 130 may display the battery non-consumable information. Alternatively, these may be combined.

The specific control content of the control device 80 that has received the second transfer signal is arbitrary, but for example, control for notifying the user that the battery 126 of the transmission device 120 is not exhausted. Therefore, the same control as the normal control of the control device 80 may be performed. As an example, regarding the opening / closing movement of the opening / closing body 30, when the input of the operation signal is received from the operation device 60, the opening / closing movement of the opening / closing body 30 is performed even if the reception of the input of the operation signal is not continued thereafter (specifically. Specifically, the closed movement or the open movement may be performed electrically (so-called “control of the opening / closing movement of the opening / closing body 30 by the self-holding operation”). Further, the display of the display unit 66 of the operation device 60 may be hidden. Further, the control content based on the presence or absence of an obstacle may be performed in the same manner as the specific control content of the control device 80 that has received the first transfer signal described above.

By such processing of SB2 to SB10 (particularly, processing of SB3, SB8 to SB10), it is determined whether or not the battery 126 of the transmission device 120 is consumed based on different determination conditions depending on the state of the opening / closing body 30. The judgment result can be notified. Therefore, as compared with the case where the presence or absence of consumption of the battery 126 of the transmission device 120 is determined under the same determination condition regardless of the state of the opening / closing body 30, the above determination result can be notified according to the state of the opening / closing body 30. It is possible to suppress false alarm of the above determination result. In particular, in the embodiment, when the communication method of the transmission device 120 is set to normal communication (that is, when it is in the operating state), the opening / closing body 30 is frequently opened / closed. Since the probability that an obstacle is detected by the plate switch 110 is relatively high, the battery 126 of the transmitter 120 is consumed by determining whether or not the battery 126 of the transmitter 120 is exhausted based on the first determination condition. It is possible to quickly determine the presence or absence of a battery, which makes it easier to ensure the safety of obstacles. On the other hand, when the communication method of the transmission device 120 is set to periodic communication (that is, when the operation is stopped), the opening / closing body 30 is hardly opened / closed, so that the seat plate switch 110 is used. Since the probability that an obstacle will be detected is relatively low, by determining whether or not the battery 126 of the transmitter 120 is exhausted based on the second determination condition, transmission is performed as compared with the case where normal communication is set. It is possible to accurately determine whether or not the battery 126 of the device 120 is exhausted, and it is possible to suppress false alarm of the determination result. Further, since the operating state is the state in which the seat plate switch 110 attached to the opening / closing body 30 is switched, and the operation stopped state is the state in which periodic communication of the transmitting device 120 is performed, the seat plate switch 110 is performed. It is possible to determine whether or not the battery 126 of the transmission device 120 is exhausted based on different determination conditions depending on the state in which the switch is switched and the state in which periodic communication is being performed, and notify the determination result. It is possible to suppress erroneous notification of the above determination result in a state where the switch 110 is switched and a state in which periodic communication is being performed.

Subsequently, in order to stop the transmission of the first radio signal by the transmitting device 120, the control unit 128 of the transmitting device 120 performs the processing of SA11 to SA13 shown in FIG. 6, and the control unit 138 of the receiving device 130 is used. The processes from SB11 to SB13 shown in FIG. 7 are performed.

First, as shown in FIG. 7, in SB11, the second determination unit 138d of the receiving device 130 determines whether or not the second transmission is possible. The method for determining whether or not the second transmission is possible is arbitrary, but for example, any frequency among the plurality of first frequencies set in the second transmission setting process of SB1 is used. 2 When an attempt is made to transmit a radio signal and it is detected by the carrier sense performed at the time of the transmission that there is no carrier, it is determined that the second transmission is possible. On the other hand, no matter which of the plurality of first frequencies set in the second transmission setting process of SB1 is used to transmit the second radio signal, there is a carrier due to the carrier sense performed at the time of the transmission. If it is detected, it is determined that the second transmission is not possible. Regarding the above-mentioned determination, the first frequency used for transmitting the first second radio signal is set to the first frequency of the first first frequency information, and the first frequency used for transmitting the second second radio signal is set. Frequency = 2nd 1st frequency information shall be set to the 1st frequency, and the transmission shall be performed sequentially based on this transmission order. Then, the second determination unit 138d of the receiving device 130 shifts to SB12 when it is determined that the second transmission is possible (SB11, Yes), and when it is determined that the second transmission is not possible (SB11). , No) shifts to SB13.

In SB12, the control unit 138 of the receiving device 130 causes the transmitting unit 135b to transmit the second radio signal using the first frequency. Specifically, the second radio signal is intermittently transmitted a plurality of times (so-called intermittent transmission) from the start of the processing of the SB 12 until a predetermined time elapses (the same applies to the processing of the SB 13 described later). After that, the control unit 138 of the receiving device 130 shifts to SB2, and thereafter repeats the processing from SB2 to SB13 in the same manner.

Here, regarding the first frequency used for transmitting the second radio signal, it is detected by carrier sense in SB11 that there is no carrier among the plurality of first frequencies set in the second transmission setting process of SB1. The first frequency is used. Even if none of the plurality of first frequencies has a carrier, as described above, the SB11 is sequentially determined based on the transmission order, and when it is determined that the second transmission is possible. Since the first frequency is used, as a result, the first frequency having an earlier transmission order is preferentially used. Further, the information included in the second radio signal includes, for example, communication type information, communication target identification information, transmission stop information, execution interval resetting information, and the like (note that the second radio signal of SB13 described later includes information). The same applies to the information contained). Of these, the "transmission stop information" means information indicating an instruction to stop transmission of the first radio signal. Further, the "execution interval resetting information" means information indicating the resetting of the periodic communication execution interval, for example, the information instructing the setting of the periodic communication execution interval changed in SB6, in SB7. It is a concept including information instructing the setting of the returned periodic communication execution interval, information not instructing the reset of the periodic communication execution interval, and the like.

In SB13, the control unit 138 of the receiving device 130 causes the transmitting unit 135b to transmit the second radio signal using the second frequency. After that, the control unit 138 of the receiving device 130 shifts to SB2, and thereafter repeats the processing from SB2 to SB13 in the same manner.

Returning to FIG. 6, in SA11, the control unit 128 of the transmission device 120 determines whether or not the second radio signal transmitted by the SB12 or SB13 is received by the reception unit 124b. The method for determining whether or not the second radio signal has been received is arbitrary, but for example, it is first transmitted on the two first and second frequencies set in the first reception setting process of SA1. Whether or not the second radio signal can be received is sequentially and repeatedly monitored. Next, when the second radio signal can be received, the communication target identification information included in the second radio signal matches the communication target identification information stored in advance in the storage unit 129 of the transmission device 120. Judge whether or not. Here, if these two communication target identification information match, it is determined that the second radio signal has been received, and if these two communication target identification information do not match, or if the second radio signal cannot be received, it is determined that the second radio signal has been received. It is determined that the second radio signal has not been received. Then, the control unit 128 of the transmission device 120 waits until the second radio signal is received (SA11, No), and when the second radio signal is received (SA11, Yes), shifts to SA12.

In the SA 12, the control unit 128 of the transmission device 120 stops the transmission of the first radio signal by the transmission unit 124a based on the transmission stop information included in the second radio signal received by the SA 11.

In the SA13, the control unit 128 of the transmission device 120 resets the execution interval of the periodic communication based on the execution interval resetting information included in the second radio signal received by the SA11. After that, the control unit 128 of the transmission device 120 shifts to SA2, and thereafter repeats the processing from SA2 to SA13 in the same manner.

Further, the method of resetting the execution interval of the periodic communication is arbitrary, but for example, when the execution interval reset information is the information instructing the setting of the execution interval of the periodic communication changed in SB6. Resets the execution interval to be reset to the execution interval of the periodic communication changed in SB6. Further, when the execution interval reset information is information for instructing the setting of the periodic communication execution interval returned by SB7, the execution interval to be reset is the periodic communication execution interval returned by SB7. Reset to. However, if the execution interval reset information is information that does not instruct the reset of the regular communication execution interval, the execution interval shall not be reset.

By such processing of SA11 to SA13 and SB11 to SB13, the transmission of the first radio signal by the transmission device 120 can be stopped, and the consumption of the battery 126 of the transmission device 120 can be suppressed. Further, in the processing of SB11 to SB13, since the second radio signal is transmitted using the first frequency and the second frequency based on the determination result of the second determination unit 138d, it is obligatory to perform carrier sense. Compared with the case where the second radio signal is transmitted using only the existing frequency, the second radio signal can be transmitted quickly and reliably without being influenced by the surrounding communication environment, and the reliability of communication can be improved. In particular, in the processing of SB13, after it is confirmed by the carrier sense regarding a plurality of first frequencies that there is a carrier, the second radio signal can be transmitted using the second frequency, and communication is performed while suppressing interference of the radio signals. Can increase the reliability of.

(Effect of embodiment)
As described above, according to the embodiment, when the transmitting device 120 or the receiving device 130 is specified to be in the operating state by the specific unit 128c for specifying the state of the opening / closing body 30 and the specific unit 128c, the detection unit When it is determined whether or not the battery 126 of the transmission device 120 is exhausted based on the detection result of 127 and whether or not the first determination condition is satisfied, and it is specified by the specific unit 128c that the operation is stopped. The battery consumption determination unit 138a for determining whether or not the battery 126 is exhausted and the battery consumption determination unit 138a for determining whether or not the battery 126 is exhausted based on the detection result of the detection unit 127 and whether or not the second determination condition is satisfied. Since the notification unit 138b for notifying the result is provided, it is possible to determine whether or not the battery 126 of the transmission device 120 is exhausted based on different determination conditions according to the state of the opening / closing body 30 and notify the determination result. Therefore, as compared with the case where the presence or absence of consumption of the battery 126 of the transmission device 120 is determined under the same determination condition regardless of the state of the opening / closing body 30, the above determination result can be notified according to the state of the opening / closing body 30. It is possible to suppress false alarm of the above determination result.

Further, when the battery consumption determination unit 138a is specified to be in the operating state by the specific unit 128c and the number of detections reaches the first number, the battery 126 is consumed as satisfying the first determination condition. If it is determined that the battery is in operation and the operation is stopped by the specific unit 128c, and the number of detections reaches the second number, the battery 126 is consumed as satisfying the second determination condition. Therefore, it is possible to determine whether or not the battery 126 of the transmission device 120 is consumed based on the number of detections that differ depending on the state of the open / close body 30, and the determination accuracy can be improved.

Further, the battery consumption determination unit 138a is specified by the specific unit 128c to be in either the operating state or the operating stopped state, and the number of detections has not reached either the first or the second. In the case, when it is specified by the specific unit 128c that it is either the operating state or the operating stopped state, either the first judgment condition or the second judgment condition, which is the judgment condition immediately before the specific, is satisfied. Since it is changed to either the first judgment condition or the second judgment condition and it is judged whether or not the battery 126 is exhausted based on the changed judgment condition, the number of detections is the first time or the second time. When the state of the opening / closing body 30 is changed when one of them is not reached, the state of the opening / closing body 30 is changed to the state of the opening / closing body 30 as compared with the case of determining whether or not the battery 126 of the transmission device 120 is consumed without changing the determination condition. It is possible to determine whether or not the battery 126 of the transmission device 120 is exhausted, and the determination accuracy can be further improved.

Further, since the operating state is the state in which the seat plate switch 110 attached to the opening / closing body 30 is switched, and the operation stopped state is the state in which periodic communication of the transmitting device 120 is performed, the seat plate switch 110 is performed. It is possible to determine whether or not the battery 126 of the transmission device 120 is exhausted based on different determination conditions depending on the state in which the switch is switched and the state in which periodic communication is being performed, and notify the determination result. It is possible to suppress erroneous notification of the above determination result in a state where the switch 110 is switched and a state in which periodic communication is being performed.

Further, since the receiving device 130 is provided with the second changing unit 138c for changing the execution interval of the periodic communication when the detection unit 127 detects the state related to the consumption of the battery 126 of the transmitting device 120, the detecting unit 127 is provided. It is possible to change the execution interval of the periodic communication performed after the state related to the consumption of the battery 126 of the transmission device 120 is detected, and it is possible to perform the periodic communication according to the state of the battery 126 of the transmission device 120.

Further, when the second changing unit 138c does not detect the state related to the consumption of the battery 126 of the transmitting device 120 after the periodic communication execution interval is changed, the periodic communication execution interval is not changed. Since it is returned to the execution interval of, the execution interval of the periodic communication changed by the second change unit 138c can be automatically returned to the execution interval before the change, and the trouble of returning the execution interval of the periodic communication can be omitted.

In this case, the transmission device 120 may include a notification unit 138b and notify information indicating the determination result of the SB 8 by the display unit 123 of the transmission device 120.

(About the 1st radio signal and the 2nd radio signal)
In the above embodiment, when the transmission device 120 transmits the first radio signal using the first frequency and the second frequency, the transmission time of the first radio signal when the first frequency is used is set to the second frequency. When the transmission time of the first radio signal when used is the same, and the radio strength of the first radio signal when the first frequency is used is the same as the radio strength of the first radio signal when the second frequency is used. I explained, but it is not limited to this. For example, the transmission time of the first radio signal when using the first frequency may be different from the transmission time of the first radio signal when using the second frequency, or the first when using the first frequency. The radio strength of the radio signal may be different from the radio strength of the first radio signal when the second frequency is used (note that the receiving device 130 transmits the second radio signal using the first frequency and the second frequency). The same applies when doing so).

Further, in the above embodiment, it has been described that the first radio signal and the second radio signal are transmitted using the first frequency and the second frequency, but the present invention is not limited to this, and for example, the first frequency or the second frequency is used. It may be transmitted using only one of the frequencies. In this case, the first determination unit 128a and the second determination unit 138d may be omitted.

(About the transmitting side frequency table and the receiving side frequency table)
In the above embodiment, it has been described that the transmitting side frequency table 129a stores two frequency information (first first frequency information, second first frequency information) associated with each channel information. Not limited to this. For example, when the transmission device 120 transmits a first radio signal using three or more first frequencies, three or more frequency information is stored in association with each channel information in the transmission side frequency table 129a. (The same applies to the receiving side frequency table 139a). Regarding the number of channel information in the transmission side frequency table 129a in this case, since the number of frequencies that can be used as the first frequency is a fixed number, the number of channel information in the transmission side frequency table 129a according to the embodiment is used. Is also a small number. Further, when the transmission device 120 transmits the first radio signal using only one first frequency, even if only one frequency information is associated and stored for each channel information in the transmission side frequency table 129a. Good (the same applies to the receiving side frequency table 139a). In this case, the number of channel information in the transmission side frequency table 129a is larger than the number of channel information in the transmission side frequency table 129a according to the embodiment.

(About communication processing)
In the above embodiment, when it is determined in SB6 that the state related to the consumption of the battery 126 of the transmission device 120 is detected by SB3 regardless of the content of the communication type information included in the first radio signal. , I explained that the execution interval of regular communication will be changed, but it is not limited to this. For example, the periodic communication is performed only when it is determined by the SB3 that the state related to the consumption of the battery 126 of the transmission device 120 is detected and the communication type information included in the first radio signal is the information indicating the periodic communication. The implementation interval may be changed.

The transmitting device or the receiving device is provided with a detecting means for detecting a state, and the specific means for specifying the state of the opening / closing body and the state of the opening / closing body operate the opening / closing body by the specific means. When it is specified that it is in the operating state, it is determined whether or not the battery is exhausted based on the detection result of the detection means and whether or not the first determination condition is satisfied, and the specific means determines whether or not the battery is exhausted. When it is specified that the state of the opening / closing body is an operation stop state in which the opening / closing body is not operated, whether the detection result of the detection means and the second determination condition different from the first determination condition are satisfied. Based on whether or not the battery is exhausted, a determination means for determining whether or not the battery is exhausted and a notification means for notifying the determination result of the determination means are provided.

In the communication system described in Appendix 1, when the determination means is specified to be in the operating state by the specific means, the detection means detects a state related to battery consumption. When the number of detections reached the first number, it is determined that the battery is exhausted, assuming that the first determination condition is satisfied, and the operation is stopped by the specific means. In this case, when the number of detections reaches the second number, which is larger than the first number, it is determined that the battery is exhausted, assuming that the second determination condition is satisfied.

In the communication system described in Appendix 2, the determination means is specified by the specific means to be either the operation state or the operation stop state, and the number of detections is the same. If either the first number of times or the second number of times has not been reached and it is specified by the specific means to be either the operation state or the operation stop state, it is immediately before the specific time. Either one of the first judgment condition or the second judgment condition, which is the judgment condition of the above, is changed to either the first judgment condition or the second judgment condition, and the battery is based on the changed judgment condition.

(Effect of appendix)
According to the communication system described in Appendix 1, the transmitting device or the receiving device has a specific means for specifying the state of the open / close body, and when the specific means specifies that the state is in operation, the detection result of the detection means. , It is determined whether or not the battery of the transmitting device is exhausted based on whether or not the first determination condition is satisfied, and when it is specified by the specific means that the operation is stopped, the detection result of the detection means. A determination means for determining whether or not the battery is exhausted based on whether or not the second determination condition is satisfied, and a notification means for notifying the determination result of the determination means are provided. Based on different determination conditions depending on the state, it is possible to determine whether or not the battery of the transmission device is exhausted and notify the determination result. Therefore, as compared with the case where the presence or absence of battery consumption of the transmitting device is determined under the same determination conditions regardless of the state of the opening / closing body, the above determination result can be notified according to the state of the opening / closing body, and the above determination can be performed. It is possible to suppress false notification of the result.

According to the communication system described in Appendix 2, when the determination means is specified to be in the operating state by the specific means and the number of detections reaches the first number, the first determination condition is satisfied. If it is determined that the battery is exhausted and the operation is stopped by the specific means, and the number of detections reaches the second number, the battery is considered to satisfy the second determination condition. Since it is determined that the battery is exhausted, it is possible to determine whether or not the battery of the transmitting device is consumed based on the number of detections that differ depending on the state of the open / close body, and the determination accuracy can be improved.

According to the communication system described in Appendix 3, the determination means is specified by the specific means as either an operating state or an operating stopped state, and the number of detections is either the first or the second. If one of the operating states or the operating stopped state is specified by the specific means, the first determination condition or the second determination condition, which is the determination condition immediately before the specific, is used. Since either one is changed to either the first judgment condition or the second judgment condition and it is judged whether or not the battery is exhausted based on the changed judgment condition, the number of detections is the first number or the first. When the state of the open / close body changes when one of the two times is not reached, it depends on the state of the open / close body as compared with the case of judging whether or not the battery of the transmitter is exhausted without changing the judgment condition. It is possible to determine whether or not the battery of the transmitter is exhausted, and the determination accuracy can be further improved.

According to the communication system described in Appendix 4, the operating state is a state in which the seat plate switch attached to the open / close body is switched, and the operation stopped state is a state in which periodic communication of the transmitting device is performed. Therefore, it is possible to determine whether or not the battery of the transmitter is exhausted based on different determination conditions depending on the state in which the seat plate switch is switched and the state in which periodic communication is being performed, and notify the determination result. , It is possible to suppress erroneous notification of the above determination result in the state where the seat plate switch is switched and the periodic communication is performed.

According to the communication system described in Appendix 5, the transmitting device or the receiving device is provided with a changing means for changing the execution interval of periodic communication when a state related to battery consumption is detected by the detecting means. It is possible to change the execution interval of the periodic communication performed after the state related to the battery consumption is detected by the means, and it is possible to perform the periodic communication according to the battery condition of the transmitting device.

According to the communication system described in Appendix 6, when the changing means does not detect the state related to battery consumption by the detecting means after the periodic communication execution interval is changed, the periodic communication execution interval is not changed. Since it is returned to the execution interval of, the execution interval of the periodic communication changed by the changing means can be automatically returned to the execution interval before the change, and the trouble of returning the execution interval of the periodic communication can be omitted.
