BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, one embodiment of the present invention will be described.
This will be described with reference to FIGS. It should be noted that the same parts as those in FIG. 4 are denoted by the same parts, and the description thereof will be omitted. FIG. 2 shows the configuration of the house locking system. The reception control device 10 is installed inside the door 2, and is connected to the control panel (signal output means) 4 by a relay harness 12 via a connector 11. Further, the reception control device 10 is connected to the electric lock 1 by a relay harness 13 a via a connector 13, and obtains an operation power supply from a commercial AC power supply via an AC adapter 14. .

FIG. 1 shows a detailed electrical configuration centering on the reception control device 10. Reception control device 10
The antenna 16 receives a lock signal or an unlock signal transmitted together with an ID code by a radio signal (airborne signal) from a remote controller (transmitter) 15. The received radio signal is demodulated by a receiving circuit 17 and is then subjected to a microcomputer (hereinafter, referred to as a microcomputer).
18 is provided.

The microcomputer 18 is provided with a clock signal from a clock circuit 19 and a reset signal from a reset circuit 20. Various setting switches 21 including dip switches provide information on various settings. ROM built in microcomputer 18
, An ID code, a lock signal, and an unlock signal transmitted from the remote controller 15 are stored together with the control program.

On the other hand, the microcomputer 18 receives an unlock signal and a lock signal from the control panel 4 via a reception buffer 22a and 22b to an input port. Conversely, the microcomputer 18 sends an electric lock 1 and a lock signal as described later. The unlock state signal and the door open signal output from the
a and 23b to the control panel 4.

The unlock signal and the lock signal are sent from the microcomputer 18 to the transmission buffers 24a and 24a from the output port.
4b, the unlocking state signal and the door opening signal are supplied from the electric lock 1 to the input port of the microcomputer 18 via the receiving buffers 25a and 25b. The microcomputer 18 corresponds to a relay unit and a control unit.

An unlock signal and a locking signal are supplied to both terminals of the actuator 1b inside the electric lock 1. For example, when the unlocking signal is at a low level and the locking signal is at a high level, the actuator 1b rotates forward to project the dead bolt 1a to the outside of the door 2 and insert the dead bolt 1a into a recess (not shown) provided on the house side. Thus, the door 2 is locked. Conversely, when the unlocking signal is at a high level and the locking signal is at a low level, the door 1 is unlocked by reversing the actuator 1b and pulling the deadbolt 1a back into the door 2.

A dead bolt 1 is provided inside the electric lock 1.
a, a switch 26 is provided which is turned on when the dead bolt 1a is retracted into the door 2 and the door 2 is unlocked in response to the above operation of the switch a.

A door opening signal is provided to the microcomputer 18.

Next, the operation of this embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing the control contents of the microcomputer 18. First, in the determination step S1 of “Remote control input?”, The microcomputer 18 determines whether a radio signal is transmitted from the remote control 15 or not.
If there is no transmission of the radio signal, "NO" is determined, and the process proceeds to the determination step S6 of "control panel input?" If a radio signal is transmitted, the transmitted ID code is stored in ROM
Is checked to see if they match, and if they match, "YES" is determined and the process proceeds to "door open?" Determination step S2. If they do not match, "NO" is determined, and the routine goes to step S6.

In the judgment step S6, the microcomputer 18
Determines whether there is an input (transmission) of a lock signal or an unlock signal by operating the numeric keypad 5, the switch 6, or the additional switch 7, and if there is no input, "N"
O ”is determined, and the process proceeds to step S1.

If it is determined in step S6 that a signal is input from the control panel 4, if the signal is output by operating the switch 6 or the additional switch 7 in the house, "YES" is determined. Then, the process proceeds to step S2. If the signal is a password output by operating the numeric keypad 5 outside the house, the microcomputer 18 checks the password against the password registered in the ROM, and if both match, determines "YES". Then, the process proceeds to step S2. If they do not match, "NO" is determined and the process proceeds to step S1. That is, in a state of waiting for input of a signal, a loop of steps S1 and S6 is performed.

At the decision step S2, the microcomputer 18
Refers to the input port and determines whether or not the door 2 is in the open state based on whether or not the door open signal is output from the electric lock 1. Door open signal is output and "YES"
When the determination is made, the process proceeds to step S1, and when the door opening signal is not output and the determination is "NO", the process proceeds to determination step S3 of "unlock signal?"

In the decision step S3, the microcomputer 18
Determines whether the signal transmitted from the remote controller 1 or the control panel 4 is an unlocking signal based on data stored in the ROM. If the transmitted signal is an unlocking signal and is determined to be "YES", the flow proceeds to the determination step S4 of "unlocking state?", Where the transmitted signal is not an unlocking signal but "N".
If "O" is determined, in this case, it is determined that the locking signal has been transmitted, and the process proceeds to "Locked?" Determination step S7.

At the decision step S4, the microcomputer 18
Refers to the input port, determines whether or not the door 2 is in the unlocked state based on whether or not the unlocked state signal is output from the electric lock 1, and determines whether or not the unlocked state signal has been output. N
When the determination is "O", the process proceeds to the processing step S5 of "Unlock". If the unlock state signal has been output and the judgment is "YES", the process directly proceeds to step S1.

In the processing step S5, the microcomputer 18
Outputs an unlock signal to the output port and transmits it to the electric lock 1. Then, the actuator 1b of the electric lock 1 rotates in the reverse direction, pulls the dead bolt 1a back into the door 2, and puts the door 2 into the unlocked state. Then, control goes to a step S1.

The processing after the judgment step S7 is for performing the processing of the above steps S4 and S5 for locking, and the microcomputer 18 locks the door 2 based on whether or not the unlocking state signal is output from the electric lock 1. It is determined whether or not the door is in the unlocked state signal. If the determination is "NO", the process proceeds to step S8 for "locking" and outputs a locking signal to the output port to lock the door 2. After the state, the process proceeds to step S1. If it is determined that the unlocking state signal has not been output and “YES”, the process directly proceeds to step S1.

That is, in the above control contents, the processing parts of steps S2 to S8 except for step S1 are performed by the control panel 4
Corresponding to the processing of the relay means for outputting the signal from the electronic lock 1 to the electric lock 1, and excluding the step S6.
The processing portions 1 to S5, S7 and S8 correspond to the processing of the control means for outputting a signal from the remote controller 15 to the electric lock 1.

As described above, according to the present embodiment, the reception control device 10 is configured to be connectable between the control panel 4 and the electric lock 1 constituting the locking system, and the microcomputer 18
Receives a lock signal or an unlock signal transmitted from the control panel 4 or the remote controller 15 and outputs a lock signal or an unlock signal to the electric lock 1.

Therefore, it is not necessary to particularly consider the input / output specifications via the control panel 4, and only the very simple input / output specifications between the control panel 4 and the electric lock 1 can be used. A function of unlocking or locking the door 2 by a radio signal using the remote controller 15 can be easily added to the system.

According to the present embodiment, the reception control device 1
0, the microcomputer 18 is connected to the control panel 4 and the electric lock 1 via the connectors 11 and 13, so that the connectors 11 and 13 and the relay harnesses 12 and 13a are replaced to control the control panel of the locking system having different specifications. And an electric lock, so that the versatility can be improved.

The airborne signal is not limited to a radio wave, but may be an electromagnetic signal, an electrostatic signal, or light. When the wiring to the control panel 4 is a two-wire system, a two-wire converter (parallel ← → serial converter) may be provided between the reception control device 10 and the control panel 4. Further, the converter may be incorporated in the microcomputer 18 in advance, and serial input / output terminals may be provided in parallel with the reception control device 10 so as to be compatible with any wiring method. By changing the control program of the microcomputer 18, for example, when signals are output from the remote controller 15 and the control panel 4 at the same time, one of the signals may be given priority.

Also, by setting the setting switch 21,
The signal transmitted from the remote controller 15 may be invalidated. For example, a determination step S1 'of "is the remote control valid?" Is provided between steps S1 and S2 in the flowchart shown in FIG. When a signal is transmitted from the remote controller 15 in step S1, the microcomputer 18 refers to the setting state of the setting switch 21 in step S1 'to determine whether the transmission signal from the remote controller 15 is valid. Judge. When the setting switch 21 is enabled, the process proceeds to step S2.
If invalidation has been set by the
Move to 6. With this configuration, security can be ensured even if the remote controller 15 is lost. Although the relay means and the control means are shared by the microcomputer 18, they may be individually configured. The locking system is not limited to a locking system for a house, but may be a locking system for a factory, a store, an office, or the like.
