Description

  The present invention relates to a wireless remote control method using a repeater.

In the wireless communication device, the function of the transmission / reception unit is switched between the normal wireless communication mode and the DTMF code string transmission mode based on an instruction from the mode switching instruction key, and the function of the transmission / reception unit is switched to the DTMF code string transmission mode. , The function corresponding to each instruction key is displayed corresponding to the display of all instruction keys, and then when the instruction key is operated, the transmission / reception unit is switched to the transmission state, and a signal corresponding to the operated instruction key is displayed. There is known a wireless communication device in which a DTMF code string output from a generation unit is transmitted from a transmission / reception unit, and the transmission / reception unit is controlled to be in a reception state when transmission of the DTMF code sequence is completed (see, for example, Patent Document 1).
Registered Utility Model No. 2600539

  Based on the contents of the DTMF code string, the wireless communication device that has received the DTMF code string can, for example, control other devices by wireless control.

  Further, in order to remotely control a controlled device via a conventional repeater, as shown in FIG. 7, a wireless communication system control for giving a control instruction wirelessly via a repeater, and a control instruction by wire via a repeater There were a wired communication system control and a local system that directly operated a repeater to give a control instruction.

  In FIG. 7, reference numeral 10 indicates a repeater, reference numeral 11 indicates a part of the correspondence between functions and function control codes in wireless communication system control, and part of the correspondence between procedures and procedure codes. Indicates a part of the correspondence between the function and the input port (reference numeral 121) and part of the correspondence between the function and the output port (reference numeral 122) in the wired communication system control, and reference numeral 13 indicates the function and the function instruction. A part of the correspondence with a key, for example, a PF key (Programmable Function) is shown.

  However, since these are independent control instruction systems, function setting and confirmation must be performed independently. Further, the function that can be set is a method of selecting from the functions prepared in advance, and when the function is not set, it cannot be used in other control instruction systems, and thus it is wasted. In the wireless communication system control, in addition to the function control code, a dedicated code (Ack / Nack code) for notifying whether or not the function control code has been received is required, and code use efficiency is wasted. Moreover, although not remote control, a PF key is also prepared as an input. Since this is also set independently of wired communication system control and wireless communication system control, setting and checking are further complicated.

  However, since the wireless communication system control, the wired communication system control, the wireless communication system control, and the PF key are independent of each other, it is necessary to set the function separately and check the operation separately. For this reason, there has been a problem that it takes enormous time to install the repeater.

  In the case of wireless communication system control, it is necessary to return information on whether or not a function control code has been received. Therefore, there is a problem that one procedure code is always required for each control instruction. Further, since the wireless communication system control, the wired communication system control, and the PF key system are independent systems, there is a problem in that priority control or exclusive control is required between the three parties. Therefore, in order to perform control by wireless communication system control, it is necessary to enter or exit from the wireless communication system control mode (Enter / Exit). For this reason, the mode control code There arises a problem in that a procedure code including “” is required separately from the function control code.

Enter / Exit mode control code and function control code have different control contents, so it is necessary to distinguish them. For this purpose, Ack / Nack code must also be divided into mode control code and function control code, and the procedure code is at least
Wireless communication system control mode Enter
Wireless communication system control mode Exit
Wireless communication system control mode Ack
Wireless communication system control mode Nack
Function control Ack
Function control Nack
6 types are required.

  In addition, because wireless communication system control, wired communication system control, and local system are independent control, even if there are unused input / output ports in wired communication system control, they cannot be used in wireless communication system control. There was also. On the contrary, there is a problem that even if there is an unused code in wireless communication system control, it cannot be used in wired communication system control.

  The present invention is based on a repeater that eliminates the need for exclusive processing, simplifies remote wireless control settings, eliminates the need for procedure codes, improves code usage efficiency, and makes it easy to determine whether control codes need to be retransmitted or not An object is to provide a wireless remote control method.

  A wireless remote control method using a repeater according to the present invention assigns a function control code for wireless communication system control to an input / output port and function instruction key for wired communication system control, and the function is an input / output port or function instruction for wired communication system control. It is shared with the key, and the response information is sent at least one or both of the time when the function control code assigned to the function is received and the time when the function based on the function control code is executed. It is characterized by.

  According to the wireless remote control method using the repeater of the present invention, the function control code of the wireless communication system control is assigned to the input / output port of the wired communication system control and the function instruction key, and the function is the input / output port or function of the wired communication system control. By setting and checking the wired communication system control and function instruction key by sharing with the instruction key, the setting and confirmation of the wireless communication system control can be limited to those for the function of the wireless communication system control only. This makes it easy to isolate the cause when a problem occurs.

  In addition, the response information is transmitted at least one or both of the time when the function control code assigned to the function is received and the time when the function based on the function control code is executed. Is possible. Hereinafter, the response information when the function control code assigned to the function is received is referred to as a previous transpond, and the response information when the function based on the function control code is executed is referred to as a subsequent transpond.

  If only the rear transpond is used, it can be replaced with the Ack / Nack code. When the function based on the function control code is not executed, the rear transpond is not transmitted, and retransmission control can be performed. Nack code is not required.

  When both transponders are used and both transponders are not output, the communication environment may be changed, and retransmission of the same function control code can be attempted. If the front transponder is output using both transponders, but the rear transponder is not output, it is determined that the function based on the function control code cannot be executed, and the same function control code is again input. A function control code for changing the state of the repeater is transmitted first before transmission. In this way, the possibility of receiving the retransmitted function control code is improved.

  Instead of pressing the function instruction key or controlling the input / output port, control is performed using the function control code for wireless communication system control, so there is no need for exclusive processing or priority processing. Equivalent processing can be performed with a function control code by wireless communication system control.

  Therefore, the procedure code is not necessary, the code can be used efficiently, and it is not necessary to identify whether the received code is a function control code or whether it is a procedure code.

  By enabling a function control code for wireless communication system control to be assigned to an input port for which a function for wired communication system control is not set, a desired sensor such as a door sensor or a switch input can be connected to the input port. Depending on the state of the door sensor or the switch, it is possible to transmit a function control code for notifying door opening by wireless communication system control. On the other hand, since the function control code for wireless communication system control can be assigned to an output port for which the function for wired communication system control is not set, the controlled device can be controlled via a relay or switch. It became possible.

  Embodiments of a wireless remote control method using a repeater according to the present invention will be described below.

  FIG. 1 is a schematic diagram for explaining a wireless remote control method using a repeater according to an embodiment of the present invention.

  In FIG. 1, reference numeral 20 indicates a repeater, reference numeral 1 indicates a part of a correspondence relationship between a procedure and a procedure code in wireless communication system control, and reference numeral 2 indicates a function, input port, and function control in wired communication system control. Part of the correspondence (reference numeral 21) with a part of the correspondence relation with the code and part of the correspondence (reference numeral 22) with the part of the correspondence between the function, the output port and the function control code Reference numeral 13 indicates a part of the correspondence between a function and a function instruction key such as a PF key and a part of the correspondence between a function control code.

  Here, in the wireless remote control method by the repeater 20 according to the embodiment of the present invention, a function control code for wireless communication control is assigned to the input / output port and PF key for wired communication control, and the function is wired communication control. Response information (at the time of receiving the function control code assigned to the function and / or the time of executing the function based on the function control code). (Transponder). The response information when the function control code is received is also referred to as a previous transpond, and the response information when the function based on the function control code is executed is also referred to as a rear transpond.

  In this way, according to the wireless remote control method by the repeater 20 according to the embodiment of the present invention, the function control code of the wireless communication system control is assigned to the input / output port and the PF key of the wired communication system control, and the function Is shared with the I / O port and PF key of the wired communication system control, so if the wired communication system control and the PF key are set and confirmed, the setting and confirmation of the wireless communication system control is a function only for the wireless communication system control. Therefore, setting and checking can be simplified, and the cause can be easily identified when a problem occurs.

  Therefore, if only the rear transpond is used, it can be replaced with the Ack / Nack code, and when the function based on the function code is not executed, the rear transpond is not transmitted and the retransmission control can be performed. / Nack code is not required.

  When both transponders are used and both transponders are not output, the communication environment may change, and retransmission of the same function code can be attempted. If the front transpond is output using both transponds, but the rear transpond is not output, it is determined that the function based on the function code cannot be executed, and the same function code is transmitted again. By transmitting the function code that changes the state of the repeater first, the possibility of receiving the retransmitted function control code is improved.

  Instead of pressing the PF key or controlling the input / output port, control is performed using the function code of the wireless communication system control, so exclusive processing and priority processing are not required, and processing equivalent to that using the PF key and input / output port Can be performed with a function control code by wireless communication system control.

  Therefore, the procedure code is not required, the code can be used efficiently, and it is not necessary to identify whether the received code is a control code or whether it is a procedure code.

  Since a function code for wireless communication system control can be assigned to an input port for which a wired communication system control function is not set, if a desired sensor such as a door sensor or switch input is connected to the input port, the door sensor or switch Depending on the state, a function code based on wireless communication system control and a function code for notifying door opening can be transmitted. Conversely, if a function code for wireless communication system control is assigned to an output port for which a function for wired communication system control is not set, it becomes possible to control the controlled device via a relay, a switch, or the like.

  Next, an example of the use of the transpond will be described with reference to FIGS. 2A and 2B, taking the case of channel change as an example.

  It is assumed that the repeater 20 is set with a channel (CH) 1 used by the forest guard and a channel (CH) 2 used by the fire brigade. The repeater 20 is normally used by the forest guard, but when a forest fire occurs, the use of the repeater 20 may be handed over to the fire brigade. At this time, if the function control code of the wireless communication system control is used to change the channel to the channel 2 while maintaining the channel 1, when the instruction is received, the previous transpond is transmitted on the channel 1 and the channel change is executed. Later, the transponder will be transmitted on channel 2. Both the forest guard and the fire brigade can recognize that a channel change has occurred by receiving a function control code, front transponder and rear transponder. The same applies when the fire fighting is over and channel 1 is returned to the Forest Guard.

  Furthermore, as another example of the use of the transponder, when the administrator of the repeater controls the plurality of repeaters 21, 22 and 23 at the same time, the frequency change in FIG. 3, FIG. 4 (a), the transformer in FIG. The pound setting, the setting of the event function of FIG. 4C, and the transmission / reception of FIG. 5 will be described by changing the frequency. In FIG. 3, a solid line arrow indicates a normal operation time, and a broken line indicates a time when the wireless communication system control is performed simultaneously. In FIG. 4, solid arrows indicate the communication direction.

  First, as a premise, the repeaters 21, 22, and 23 are independently operated in arbitrary channels so that the frequencies do not overlap. The transmission power is also adjusted so as not to interfere. Therefore, in order to control a repeater by wireless communication system control, an administrator must transmit a function control code for each frequency of each repeater. In order to make it possible to control simultaneously from this precondition and to return to normal independent operation, each repeater is set as shown in FIG. 4 and controlled as shown in FIG.

  This will be further described. (A) The administrator switches the repeater 21 to an accessible channel. (A) The repeater 21 is instructed to change the channel from channel 1 to channel 15 by the function control code for wireless communication system control. (C) The transmission output of each repeater thereafter is set to an output that can be transmitted and received between the repeaters. (D) The repeater 21 returns Ack to the manager with the previous transponder. (E) The repeater 21 changes the channel 1 to the channel 15 and transmits the rear transpond. (F) The repeater 22 changes the channel 1 to the channel 15 by the transpond after the repeater 21 and transmits the transpond. (G) The repeater 23 changes the channel 1 to the channel 15 by the transpond after the repeater 22, and then transmits the transpond. (H) At this point, the chain of manager → repeater 21 to repeater 23 → manager and instruction is configured.

  (K) The manager radio changes channel 1 to channel 15 by transpond after the repeater 23. (E) The administrator instructs the repeater 21 to change the channel (CH15) using the function control code of the wireless communication system. (S) The repeater 21 transmits the front transpond and changes the channel 15 to the channel 16. (F) The repeater 22 transmits the front transpond and changes the channel 15 to the channel 16. (S) The repeater 23 changes the channel 15 to the channel 16 and then transmits the transponder. (C) The manager radio changes channel 15 to channel 16. (G) Now, both the transmission and reception frequencies are changed, and an instruction chain is configured.

  (T) After this, a plurality of repeaters can be controlled simultaneously with an arbitrary function control code for wireless communication system control. (H) Finally, if a reset code is transmitted, the normal channel is restored and repeater operation is performed.

  As described above, in FIGS. 3 to 5, the channel 15 is routed once in order to switch both the transmission and reception frequencies from the normal channel frequency operating the repeater to the control-dedicated frequency. If the reception frequency that is normally used may be used, the same can be achieved without going through the channel 15. Even in this case, if signaling is set to a frequency or function control code different from the normal operation frequency, access by a third party during wireless communication system control can be prevented. The procedure in this case is illustrated in FIG.

  As described above, according to the wireless remote control method using the repeater of the present invention, the exclusion process is not required, the function control code setting of the wireless communication system control is simplified, the procedure code is not required, and all the function control codes. This improves the code usage efficiency. In addition, it is possible to distinguish whether a function control code has been received and whether a function has been executed by using the front transpond and the rear transpond instead of a simple Ack / Nack code. In addition to making it easier to determine whether or not to resend, it can be used for purposes other than Ack / Nack.
