TECHNICAL FIELD OF THE INVENTION
The present invention relates to a remote control system used for an opening / closing device such as a shutter, a door, a window, an overhead door, a roll screen, a blind, an awning device, a gate, a gate, and the like, and particularly to a remote control system for an opening / closing device suitable for opening and closing a shutter.
[0002]
[Prior art]
Conventionally, a remote control system for a switchgear stores the same ID code in both the transmitter and the receiver at the manufacturing stage in order to specify a transmitter that can be remotely controlled with respect to the receiver. There is a device in which the ID code is included in transmission data transmitted from a device to a receiver, and only when the receiver authenticates the ID code, the opening / closing device is controlled according to the transmission data.
By the way, according to the conventional remote control system for a switching device, when the transmitter is stolen or lost, the ID code stored in the receiver is deleted or both the receiver and the new transmitter are used. In such a case, a trouble such as re-registering a new ID code is required.
Therefore, a password specified in advance by the operator is transmitted from the transmitter to the receiver and registered in the receiver, and when the transmitter is stolen or lost, the password transmitted from the transmitter is transmitted. An invention has been proposed in which the old ID code stored in the receiver can be erased or rewritten only when the number is authenticated by the receiver (for example, see Patent Document 1).
The present invention can prevent the ID code from being registered by a third party who does not know the password, and can easily switch between the registration operation and the control operation on the receiver side on the transmitter side. This remote control system also has an operational advantage that it can be performed, and has excellent security and operability.
[0003]
However, according to the latter conventional technique described above, when registering an ID code, a password is input by a push-button operation, and therefore, particularly when a plurality of transmitters are provided corresponding to one receiver. It is necessary to input a password to each transmitter by operating a push button.
It is also desirable to minimize the possibility that the owner of the transmitter will notice theft or loss of his / her transmitter and use the transmitter by a third party during that time.
That is, it is preferable that the operability and security of the transmitter can be further improved.

For example, it is considered appropriate to select a stop operation or an open operation when focusing on cases where an object is likely to come into contact with a closed opening / closing body and it is desired to avoid this, and another example is crime prevention. For the above reasons, it is preferable to close as soon as possible, and it is considered appropriate to select the closing operation if the case where there is no particular need to restrict the person who issues the closing instruction is emphasized. That is, an appropriate operation may be performed in consideration of the characteristics, use, purpose, and the like of the switchgear, regardless of whether the personal identification data has been authenticated.

[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The remote control system A for the switching device receives the transmission data 90 (see FIG. 4) transmitted from the transmitter 10 by the receiver 20, and controls the switching device 30 by the output from the receiver 20 according to the transmission data. (See FIGS. 1 and 2).
[0014]
The transmitter 10 includes a transmission circuit unit 12, a personal identification sensor unit 14, a personal identification data storage unit 15, an ID code storage unit 16, and an operation button unit in a rectangular box-shaped case main body 11 made of synthetic resin, lightweight metal, or the like. 17, a control circuit section 18 and the like, the operation button section 17 and the personal identification sensor section 14 are partially exposed from the case body 11 (see FIG. 3), and a power supply section for supplying power to the respective sections (Not shown).
The power supply unit is built in the case main body 11, and is a power supply circuit that adjusts power supplied from a dry cell, a rechargeable battery, another battery, or a car battery outside the case main body 11 to a predetermined voltage and supplies the power to each unit. The power supply circuit may be any mode, such as a power supply circuit that converts a commercial power supplied from outside the case body 11 to a DC voltage of a predetermined voltage and supplies the DC voltage to the respective units.
[0015]
The transmission circuit unit 12 digitally modulates the transmission data 90 input from the control circuit unit 18 according to a modulation method such as ASK (Amplitude Shift Keying) modulation or FSK (Frequency Shift Keying) modulation, and is built in the case body 11. The signal is transmitted from the transmitted transmission antenna 13 to the space, and is provided with a band-pass filter, a power amplifier, and the like as necessary.
[0016]
The personal identification sensor unit 14 is a well-known fingerprint sensor that captures an uneven pattern of a fingerprint of a contacted finger as a change in the capacitance of a large number of capacitors provided inside the sensor surface and outputs a signal as fingerprint data. The sensor surface is exposed from the surface of the case body 11.
The fingerprint data output from the personal identification sensor unit 14 is input to a control circuit unit 18 described later, and is handled as personal identification data by a program stored in a memory in the control circuit unit 18.
[0017]
The personal identification data storage section 15 is a so-called non-volatile memory in which the written data is not erased even when the power is turned off, and the personal identification sensor section 14 is operated in accordance with a command from a program in the control circuit section 18. Is stored.
[0018]
The non-volatile memory constituting the personal identification data storage unit 15 includes, for example, an electrically erasable programmable read-only memory (EEPROM) and a flash memory. In order to facilitate partial rewriting of the identification data, it is preferable that the flash memory be a random read / write flash memory rather than an EEPROM in which data cannot be rewritten in bit units.
[0019]
The ID code storage unit 16 is a non-volatile memory such as an EEPROM or a flash memory, like the personal identification data storage unit 15, and has the same ID as an ID code stored in an ID code storage unit 24 of the receiver 20, which will be described later. Remember the code.
The ID code is a digital code stored when the transmitter 10 and the receiver 20 are manufactured or shipped, and a different value is set for each remote control system A for the switching device.
Since the ID code storage unit 16 stores an ID code having a smaller data amount than the fingerprint data obtained by digitizing a fingerprint image into a digital signal, the storage capacity of the ID code storage unit 16 is smaller than that of the personal identification data storage unit 15. Are selected.
[0020]
The operation button unit 17 is a switch base having three contacts of an open switch 17a, a stop switch 17b, and a close switch 17c, and exposes the pressing operation surfaces of the switches 17a, 17b, 17c from the surface of the case body 11. Together with a protective film.
As a preferable specific example of the operation button section 17, from the viewpoint of enabling the transmitter 10 to be thin and light, a circuit pattern of a conductive paste is screen-printed on a synthetic resin film, and members such as spacers are overlapped. Thus, a so-called membrane switch constituting a thin switch is used.
[0021]
In addition, when the operator presses the operation button unit 17 or touches the personal identification sensor unit 14 above the operation button unit 17 on the surface of the case main body 11, the operator responds to the operator. A response unit 19 (see FIG. 3) is provided. According to the present embodiment, the response section 19 uses a light emitting body such as a light emitting diode, but may be a sound generator that generates a signal sound or a sound.
[0022]
The control circuit unit 18 is a so-called microcomputer in which a CPU (Central Processing Unit), a memory, an input / output port, and the like are connected by a bus. The control circuit unit 18 operates the CPU according to a program stored in the memory. Input / output data.
[0023]
The control circuit unit 18 includes a personal identification data authentication unit, an ID code transmission unit, and a registration unit, which will be described later, as programs in the memory.
[0024]
The personal identification data authenticating means collates the personal identification data previously captured from the personal identification sensor unit 14 and stored in the personal identification data storage unit 15 with the personal identification data captured from the personal identification sensor unit 14 later. Then, it is determined whether or not the subsequent personal identification data has been authenticated.
Further, the ID code transmitting means transmits the ID code 92 read from the ID code storage unit 16 from the transmitter 10 to the receiver 20 when the personal identification data after authentication is authenticated by the personal identification data authentication means. The transmission data 90 (see FIG. 4) is transmitted.
Further, the registration means stores the personal identification data serving as master data in the personal identification data storage unit 15 and then authenticates the personal identification data taken in from the personal identification sensor unit 14 by comparing it with the master data. Under the condition, the personal identification data taken again from the personal identification sensor unit 14 is stored in the personal identification data storage unit 15 as the additional data.
[0025]
The control circuit section 18 can be constituted by a single microcomputer, but may be constituted by a plurality of microcomputers if necessary.
As a preferred example, the control circuit section 18 is composed of two microcomputers, and the personal identification data authentication means having a relatively large data amount is executed by one microcomputer, and the other processing is performed in parallel by the other microcomputer. If executed, the processing time in the control circuit unit 18 can be reduced, and the responsiveness of the switching device 30 can be improved.
[0026]
Next, the configuration of the receiver 20 will be described in detail.
The receiver 20 includes a tuner unit 21, a relay drive unit 23, an ID code storage unit 24, a control circuit unit 25, and the like in a rectangular box-shaped case body (not shown) made of synthetic resin, lightweight metal, or the like ( In addition, a power supply unit (not shown) similar to the power supply unit in the transmitter 10 is provided to supply power to each unit.
[0027]
The tuner unit 21 is an electronic circuit that captures the transmission data 90 transmitted from the transmitter 10 by the reception antenna 22, demodulates the data by a demodulation circuit, and inputs the demodulated data to the control circuit unit 25. And a low-pass filter.
[0028]
The relay drive unit 23 converts a control signal input from the control circuit unit 25 into an electric signal for controlling and operating the switching device 30, and sends the signal to a control operation relay circuit (not shown) provided in the switching device 30. The A / D converter is provided with an A / D conversion circuit and an amplification circuit as required.
[0029]
The ID code storage unit 24 is a non-volatile memory having the same configuration as the ID code storage unit 16 of the transmitter 10, and has a smaller storage capacity than the personal identification data storage unit 15.
[0030]
The control circuit unit 25 is a microcomputer in which a CPU (Central Processing Unit), a memory, an input / output port, and the like are connected by a bus, similarly to the control circuit unit 18, and controls the CPU by a program stored in the memory. Operate and input / output data through the input / output port.
[0031]
The control circuit unit 25 receives the transmission data 90 transmitted by the transmitter 10 as a program in the memory, and transmits the ID code 92 (see FIG. 4) included in the transmission data 90 to the receiver 20. It is provided with a means for determining whether or not the ID code stored in the ID code storage unit 24 on the side matches, and other control means.
[0032]
The opening / closing device 30 includes an opening / closing body (not shown) such as a shutter that opens and closes, a driving source (not shown) such as a motor that drives the opening / closing body, and a control operation relay that controls the driving source in a forward / reverse direction. A circuit (not shown) and the like are provided, and the opening / closing body is opened, stopped, or closed in accordance with an electric signal input from the relay driving unit 23 of the receiver 20 to the control operation relay circuit.
[0033]
Next, processing by the transmitter 10 and the receiver 20 will be described in detail based on the flowcharts shown in FIGS.
First, the control circuit unit 18 of the transmitter 10 determines whether or not the power has been turned on in accordance with a command of a program stored in a memory in the control circuit unit 18 (step 41).
In this case, the operation of turning on the power may be performed by a slide switch (not shown) provided on the outer surface of the case body 11, but from the viewpoint of cost reduction and the like, without providing a separate slide switch, The control circuit unit 18 determines that the power is ON by the combination of the three switches of the open switch 17a, the stop switch 17b, and the close switch 17c, or the operation in which any of the three switches is continuously pressed for a predetermined time. According to the present embodiment, the operation when any one of the three switches of the open switch 17a, the stop switch 17b, and the close switch 17c is first pressed is turned on.
[0034]
If it is determined in step 41 that the power is ON, step 42 described later is executed. If it is determined that the power is OFF, the waiting state of the power ON operation is continued.
[0035]
Next, in step 42, the control circuit unit 18 of the transmitter 10 determines whether to execute the registration processing or the control processing according to the operation of the operation button unit 17.
In step 42, the button operation by the operation button unit 17 is a combination operation of the three switches 17a, 17b, and 17c, or an operation in which any one of the switches is continuously pressed for a predetermined time, as in step 14. According to the present embodiment, when the open switch 17a is pressed for 10 seconds or more, the control circuit 18 determines that the control process is performed.
[0036]
The control circuit unit 18 executes the control processing routine (step 43) shown in the flowchart of FIG. 6 when it is determined in step 42 that the control processing is to be executed. The registration processing routine (step 44) shown in the flowchart of FIG. Then, after any of these operations, the power is turned off (step 45), and the state of waiting for the power-on operation (step 41) is continued.
[0037]
In the control processing routine (see FIG. 6), first, the personal identification sensor unit 14 is brought into contact with the fingertip of the operator to detect personal identification data (fingerprint data) (step 51). At this time, when the input of the personal identification data to the personal identification sensor unit 14 is completed, the response unit 19 emits light for a predetermined time (not shown) to notify the operator of the completion of the input.
[0038]
Thereafter, the timer in the control circuit section 18 operates (step 52).
Then, the control circuit unit 18 determines whether or not the stop switch 17b has been turned on (step 53). If the stop switch 17b is on, it executes step 53a, and if it is off, it executes step 54.
[0039]
In step 54, the control circuit unit 18 determines whether or not the open switch 17a has been turned on. If the switch is on, step 54a is executed.
[0040]
Further, in step 55, the control circuit unit 18 determines whether or not the close switch 17c has been turned ON. If the switch is ON, step 55a is executed, and if it is OFF, step 56 is executed.
[0041]
In each of the steps 54a and 55a, the personal identification data (fingerprint data) detected in the step 51 and the personal identification data (fingerprint data) registered in the personal identification data storage unit 15 by a registration process described later are stored. To determine whether they match. Specifically, the control circuit unit 18 determines whether or not the two pieces of personal identification data, which are the image data of the fingerprint, match by a pattern matching method that is a well-known image processing technique.
[0042]
In step 54a, if the personal identification data matches, step 54b is executed, and if the personal identification data does not match, step 55 is executed.
In step 55b, if the personal identification data matches, step 55b is executed. If the personal identification data does not match, step 56 is executed.
[0043]
In each of steps 53a, 54b, and 55b, the control circuit 18 forms transmission data 90 having the format shown in FIG. 4 and inputs the transmission data 90 to the transmission circuit 12. Then, the transmission circuit section 12 transmits the transmission data 90 from the transmission antenna 13.
[0044]
The transmission data 90 includes a predetermined head code 91 (or a sequential flag) indicating the head of the data, an ID code 92 read from the ID code storage unit 16, and one of the steps 53a, 54b, and 55b. This is a serial transmission code composed of a control code 93 that differs depending on whether the time has elapsed.
That is, in the step 53a, the control code 93 in the transmission data 90 is constituted by a predetermined digital code indicating a stop signal, and in the step 54b, the control code 93 is constituted by a predetermined digital code indicating an open signal, In step 55b, the control code 93 is constituted by a predetermined digital code indicating a close signal.
[0045]
Then, the control circuit unit 18 executes the processing of steps 53a, 54b, and 55b, and then executes step 53 again.
[0046]
In step 56, the control circuit unit 18 determines whether or not the timer operated in step 52 has passed a predetermined time (for example, 5 seconds). After ending the routine, the above-described step 45 is executed, and if the predetermined time has not elapsed, the cycle from step 53 to step 56 is repeated.
[0047]
That is, according to the control processing routine, when the stop switch 17b or the close switch 17c is pressed within the predetermined time, the personal identification sensor 14 first takes in the personal identification sensor 14 by the registration processing routine described later. The personal identification data stored in the data storage unit 15 is compared with the personal identification data captured from the personal identification sensor unit 14 later, and it is determined whether or not the subsequent personal identification data has been authenticated. The transmission data 90 is transmitted according to the determination.
When the open switch 17a is pressed within the predetermined time, the transmission data 90 is transmitted regardless of whether the personal identification data has been authenticated.
[0048]
According to the illustrated example, it is preferable that the stop switch 17b can be operated regardless of whether the personal identification data is authenticated so that the emergency stop of the opening / closing device 30 can be performed by a person other than the specific operator. Although an example has been described, the stop switch 17b may also be operable on condition that the personal identification data has been authenticated, depending on the use and purpose of the opening / closing device 30.
Further, according to the illustrated example, each of the open switch 17a and the close switch 17c can be operated on condition that the personal identification data is authenticated. Only one of the switch 17a and the close switch 17c may be made operable on condition that the personal identification data is authenticated. It is preferable that the operation can be performed on condition that the user is authenticated.
[0049]
Next, the registration processing routine shown in FIG. 7 will be described.
First, the control circuit unit 18 of the transmitter 10 detects personal identification data (master fingerprint) as master data when the fingertip of the operator contacts the personal identification sensor unit 14 (step 61). At this time, when the input of the personal identification data to the personal identification sensor unit 14 is completed, the response unit 19 emits light for a predetermined time to notify the operator of the completion of the input.
[0050]
Next, the control circuit unit 18 determines whether or not there is already registered personal identification data in the personal identification data storage unit 15 (step 62). Step 63 is executed, and if not, step 62a is executed.
[0051]
In step 62a, the personal identification data detected in step 61 is stored in the personal identification data storage unit 15 as master data (master fingerprint) to be registered first, and the registration processing routine ends.
[0052]
In step 63, the personal identification data detected in step 61 is compared with the master data (master fingerprint), which is the personal identification data registered first in the personal identification data storage unit 15, and whether or not there is a match is determined. Then, if they match, step 64 is executed; otherwise, the registration processing routine is terminated.
[0053]
In step 64, when the fingers of different operators or different fingers of the same operator are brought into contact with the personal identification sensor unit 14, the personal identification data for additional registration is detected, and the response unit 19 is activated. It emits light for a predetermined time.
In step 65, the personal identification data is additionally registered in the personal identification data storage unit 15 as additional data (additional fingerprint data), and thereafter, the registration processing routine ends.
[0054]
According to the registration processing routine, the additional data (additional fingerprint data) can be registered on condition that the master data (master fingerprint) matches. For example, the same valid operator can It is possible to register a plurality of fingerprints such as forefinger fingerprints, and to register a fingerprint with a valid operator and its related persons. Registration can be prevented.
[0055]
In the registration processing routine, the additional data can be registered on the condition that the master data matches. However, the additional data can be changed on the condition that the master data matches. Is also possible.
For example, between the step 63 and the step 64, a step of allowing the operator to select whether to register additional data or change the additional data by a combination operation of the operation button unit 17, and to register the additional data. In this case, the above-mentioned step 64 is executed, and in the case of changing the additional data, a step of allowing the operator to input the number of the registered additional data to be changed by operating the operation button unit 17, It may be provided with a step of detecting the personal identification data (fingerprint data) later, a step of replacing the detected personal identification data (fingerprint data) with registered personal identification data to be changed, and the like.
[0056]
Next, processing by the receiver 20 shown in the flowchart of FIG. 8 will be described.
The control circuit unit 25 of the receiver 20 waits for the transmission data 90 (see FIG. 4) received by the tuner unit 21 and demodulated by the tuner unit 21 to be input, and when the transmission data 90 is input. Step 72 described later is executed (step 71).
[0057]
In step 72, the control circuit unit 25 reads the transmission data 90 in order from the head code 91 at the head thereof, and stores the ID code 92 included in the transmission data 90 and the ID code stored in the ID code storage unit 24 of the receiver 20. Determine whether the code matches.
Then, when the ID codes match, the control circuit unit 25 executes step 73 described below, and when the ID codes do not match, the control circuit unit 25 continues the waiting state of the demodulated transmission data 90 (step 71).
[0058]
In step 73, if the control code 93 included in the transmission data 90 relates to the stop command, step 73a is executed. Otherwise, the process by the control circuit unit 25 shifts to the next step 74.
Similarly, in step 74, if the control code 93 included in the transmission data 90 is related to the open signal, step 74a is executed. Otherwise, the process by the control circuit unit 25 shifts to the next step 75.
In step 75, if the control code 93 included in the transmission data 90 is related to the closing signal, step 75a is executed. Otherwise, step 71 (waiting state of the transmission data 90) is executed.
[0059]
In each of the steps 73a, 74a, and 75a, a control signal corresponding to the control code 93, that is, any one of a stop signal, an open signal, and a close signal is output to the relay drive unit 23, and thereafter, Step 71 (waiting for the transmission data 90) is executed.
[0060]
According to the opening / closing device remote controller system A having the above-described configuration, the personal identification data (fingerprint data) input by the operator matches the personal identification data (fingerprint data) stored in the transmitter 10. In addition, on the condition that the ID codes of both the transmitter 10 and the receiver 20 match, the switching device 30 can perform a predetermined control operation.
[0061]
According to the transmitter 10 illustrated in FIG. 3, the personal identification sensor unit 14 is disposed at a portion other than the operation button unit 17 on the surface of the case main body 11. By arranging on the operation button unit 17 like the device 10 ′, the operation of inputting the personal identification data by contacting the personal identification sensor unit 14 and pressing the operation button unit 17 to control the opening / closing device 30 are performed. The operation and the operation may be performed simultaneously.
In the transmitter 10 ′, the personal identification sensor unit 14 is disposed so as to be superimposed on the upper surface of the open switch 17a of the operation button unit 17. According to the program of the control circuit unit 18, in the flowchart shown in FIG. Step 55a is omitted, and if the closing switch 17c is ON in step 55, step 55b is directly executed.
[0062]
According to the transmitter 10 ', when the individual identification sensor unit 14 on the open switch 17a is pressed by the operator, the individual identification data (fingerprint data) of the operator is read into the control circuit unit 18 and the individual identification data is read. Only when the control circuit unit 18 authenticates the opening and closing operation, the opening and closing device 30 performs the opening operation. When the stop switch 17b or the close switch 17c is pressed, the opening / closing device 30 performs an operation according to the switch regardless of the authentication of the personal identification data.
The transmitter 10 'has a preferable mode in which the personal identification sensor unit 14 is disposed on the open switch 17a, particularly in consideration of security. However, depending on the use and purpose of the opening and closing device 30, the personal identification sensor 14 may be used. The sensor unit 14 may be arranged on the stop switch 17b or the close switch 17c.
[0063]
Further, according to the above embodiment, the amount of information transmitted from transmitter 10 to receiver 20 is reduced by not including personal identification data in transmission data 90 (see FIG. 4). Although the responsiveness of the opening and closing device 30 is improved, the microcomputer used in the control circuit unit 18 and the control circuit unit 25 performs processing such as transmission of personal identification data and authentication at such a high speed that the user does not feel troublesome. Then, as in another example shown in FIGS. 10A and 10B, transmission data 90 ′ or 90 ″ including personal identification data 94 may be transmitted from the transmitter 10 to the receiver 20. Good.
[0064]
When the transmission data 90 'is transmitted from the transmitter 10 to the receiver 20, whether or not the transmitter 10 and the receiver 20 correspond to each other is determined by the transmitted personal identification data 94. Since the determination is sufficient, the above-described ID code can be made unnecessary.
As a specific example of this case, the ID code storage unit 16 is deleted from the configuration of the transmitter 10 in FIG. 1, and the ID code storage unit 24 is deleted from the configuration of the receiver 20 in FIG. In addition, a step (72) is added to the personal identification data 94 transmitted from the transmitter 10 and the personal identification data stored in the personal identification data storage unit of the receiver 20 in the flowchart of FIG. May be determined as a step of determining whether or not.
[0065]
When transmitting the transmission data 90 ″ from the transmitter 10 to the receiver 20, the condition that both the matching of the ID code 92 and the matching of the personal identification data 94 are confirmed on the receiver 20 side is a condition. The opening and closing device 30 is controlled.
As a specific example of this case, a personal identification data storage unit (not shown) is added to the configuration of the receiver 20 in FIG. 2, and the transmission from the transmitter 10 is performed between steps 72 and 73 in the flowchart of FIG. A step of determining whether or not the personal identification data 94 and the personal identification data stored in the personal identification data storage unit of the receiver 20 match may be provided.
[0066]
Further, according to the above-described embodiment, the operation button unit 17 is constituted by the three switches of the open switch 17a, the stop switch 17b, and the close switch 17c, but the operation button unit 17 is provided with only one contact switch. It is also possible to adopt a mode not shown. In this aspect, one type of control code 93 corresponding to the one contact is transmitted from the transmitter 10 to the receiver 20, and the receiver 20 monitors the open / close state of the opening / closing device 30 with a sensor or the like, and When the control code 93 is input, the switching device 30 is controlled to perform the closing operation when the switching device 30 is in the open state, and to perform the opening operation when the switching device 30 is in the closed state. The opening operation is performed on condition that at least the transmitter 10 or the receiver 20 has authenticated the personal identification data. Note that, in this embodiment, the opening / closing device 30 is not stopped during opening / closing.
[0067]
In the remote control system A for the switching device according to the above-described embodiment, the control circuit unit 18 of the transmitter 10 preferably performs both the process relating to the verification of the personal identification data and the process relating to the registration of the personal identification data. Although an example is shown, a part or all of the two processes may be performed by the control circuit unit 25 of the receiver 20, or the control circuit unit 18 of the transmitter 10 and the control circuit unit 25 of the receiver 20 The sharing of processing by the control circuit unit 18 and the control circuit unit 25 can be freely changed, for example, by cooperating with each other. Further, the processing performed by the control circuit unit 18 can be performed by the control circuit unit 25 again.
[0068]
Further, as a specific example in which the above-mentioned processing allotment is changed, the transmitter 10 performs a simple collation of the personal identification data as a primary processing, and if it is determined that the primary authentication has been successfully performed by the collation, the receiver 20 further performs May be configured to perform the original detailed collation.
According to this configuration, the amount of stored data and the amount of data processing on the transmitter 10 side can be reduced, and in the case of a collation error in the primary processing, transmission of personal identification data to the receiver 20 becomes unnecessary. The amount of communication and the number of times of communication can be reduced.
In general, compared to a portable transmitter that is small and lightweight, a receiver that is fixed in the vicinity of the switch has a margin in the internal space and has a processing function for the switch. Because of the necessity and the like, it has room for a large amount of memory capacity and processing functions. In the above specific example, the processing amount on the receiver 20 side is increased, and the general configuration of the transmitter and the receiver is effectively used.
[0069]
【The invention's effect】
The present invention is configured as described above, and has the following functions and effects.
According to the first invention, it is determined whether or not the operator is a person who is permitted to operate by a contact act on the personal identification sensor unit by the operator. Enable remote control, otherwise disable said remote control.
Therefore, a remote operation can be permitted or denied to the operator in accordance with an extremely simple input operation performed by the operator, thereby providing a remote control system for an opening / closing device excellent in operability and security. be able to.
[0070]
In addition, according to the second invention, the personal identification data is authenticated on the transmitter side, so that the transmission data transmitted from the transmitter to the receiver does not include the personal identification data. Even if personal identification data such as data is data having a relatively large amount of information, there is no need to transmit the personal identification data having a large amount of information to the receiver.
Therefore, by minimizing the amount of information transmitted from the transmitter to the receiver, the time from when the transmitter is operated to when the switchgear is controlled is shortened. Becomes possible.
In addition, since there is no need to provide a personal identification data storage unit on the receiver side, the circuit configuration on the receiver side can be simplified and the cost can be reduced.
[0071]
Further, according to the third aspect, the transmission data transmitted from the transmitter to the receiver includes an ID code, the personal identification data is authenticated on the transmitter side, and the ID code matches on the receiver side. Since the opening / closing device is controlled under the condition, the security can be further improved. In particular, even when the transmission data transmitted from the transmitter to the receiver does not include personal identification data, the remote operation with superior responsiveness and security can be achieved by transmitting an ID code having a relatively small amount of information. Becomes possible.
[0072]
Further, according to the fourth invention, since the predetermined operation in the opening and closing device is enabled regardless of the judgment by the personal identification data authenticating means, for example, the opening and closing device can be operated regardless of the authentication of the personal identification data. Suitable control according to the use and purpose of the switchgear can be performed, for example, by enabling an emergency stop to improve the safety of the switchgear.
[0073]
Further, according to the fifth aspect, the personal identification data to be captured again is not stored as additional data unless the personal identification data to be captured later is authenticated by the previously stored master data.
Therefore, for example, the same legitimate operator can register a plurality of fingerprints such as the fingerprint of the thumb and the index finger, and the legitimate operator and its related persons can register their fingerprints, respectively. A fingerprint of a third party unrelated to the operator is registered, and the remote control of the opening / closing device by the third party can be more reliably prevented.
[0074]
Further, according to the sixth aspect, the operation of inputting the personal identification data by contacting the personal identification sensor unit and the operation of pressing the operation button for controlling the opening / closing device can be performed simultaneously, so that further operation is possible. It is possible to provide a remote control system for a switchgear having excellent operability.
