[0002]

2. Description of the Related Art An electric lock control device for supplying electric power to an electric lock attached to a door to electrically lock and unlock the electric lock is
Conventionally, a remote input / output unit for remotely controlling an electric lock from a plurality of locations is often used by connecting to a main body unit directly connected to the electric lock.

The remote input / output unit is a display unit such as a lamp for displaying an electric lock, an unlocked state and a door open / closed state, and an operation unit such as a push button for locking and unlocking the electric lock. Are connected.

In such an electric lock control device, the present applicant has previously filed Japanese Patent Application No. 6-262395 to provide a plurality of states such as locking, unlocking and opening / closing of a door from a main body portion to a remote input / output portion. When transmitting the state, the main unit sends the status to the remote I / O unit by changing the voltage value, and the remote I / O unit sends a control signal for locking and unlocking operation to the main unit by changing the energizing current. We proposed a configuration in which the wiring to the remote input / output unit is two-wire.

Hereinafter, the conventional electric lock control device will be described with reference to the drawings. FIG. 3 is a block diagram showing a conventional electric lock control device. In FIG. 3, 1 is an electric lock, 2 is an electric lock control device, and 3 is a remote control means. The electric lock control device 2 has a main body portion 4 and a remote input / output portion 5,
The main body 4 and the remote input / output unit 5 are connected by two-wire wirings 6 and 7. The electric lock 1 is connected to the main body 4, and the remote control means 3 is connected to the remote input / output unit 5.

The main body 4 has a control means 8, a voltage output means 9 and a current detection means 10 inside. The control means 8 inputs the state signal from the electric lock 1 and outputs it to the voltage output means 9, and the voltage output means 9 receives a signal indicating the state of the electric lock from the control means 8 and sets a different constant voltage value according to it. Wiring 6,
Output between 7 The current detecting means 10 detects a change in the value of the energizing current on the wirings 6 and 7, and outputs it to the control means 8 to drive the electric lock 1. The remote input / output unit 5 receives voltage from the wirings 6 and 7 and outputs voltage according to the voltage value between the wirings 6 and 7, and a control signal from the outside. An energizing means 12 for energizing a constant current is provided above.
The remote control means 3 receives an input from the voltage detection means 11 inside,
A display unit 13 for displaying a locked / unlocked state, a door open / closed state, etc., and a command signal received from the user for locking / unlocking the electric lock 1 by an energizing means 12 of the remote input / output unit 5. It has an operation unit 14 for outputting to.

The operation of the above configuration will be described below. The lock / unlock and door open / close state signals output from the electric lock 1 are input to the control means 8 of the main body portion 4, and the control means 8 drives the voltage output means 9 in response thereto. The voltage output means 9 outputs a signal from the control means 8, that is, a constant voltage value according to the state of the electric lock 1, between the wirings 6 and 7. The voltage detection means 11 of the remote input / output section 5 detects the voltage value between the wirings 6 and 7 and drives the display section 13 of the remote control means 3 to display a voltage value, that is, a display according to the state of the electric lock 1. Let

As described above, since the voltage output means 9 of the main body portion 4 outputs the state of the electric lock 1 to the voltage detection means 11 of the remote input / output portion 5 in the form of a voltage value, the main body portion 4 and the remote input terminal 5 are connected. Wiring to the output unit 5 is only two lines 6, 7 and a plurality of status displays such as locking, unlocking and opening / closing of the electric lock 1 are displayed on the display unit 1.
3 can be performed.

When the user operates the operation unit 14 of the remote operation means 3 to lock or unlock the electric lock 1, the operation unit 1
Reference numeral 4 drives the energizing means 12 of the remote input / output unit 5, and the energizing means 12 applies a constant current to the wires 6 and 7. The current detection means 10 of the main body portion 4 detects that the energization current on the wirings 6 and 7 has changed, and outputs a signal to the control means 8. The control means 8 receives this signal and drives the electric lock 1 to lock or unlock it.

As described above, in the above-mentioned conventional electric lock control device, the function of the voltage output means 9 conveys the state to the remote input / output section 5 by the change of the voltage value from the main body section 4, and the function of the energizing means 12 operates. Then, by transmitting a control signal for locking and unlocking operation from the remote input / output unit 5 to the main body unit 4 according to the change of the energization current, the wiring from the main body unit 4 to the remote input / output unit 5 is changed to two-wire wiring 6, 7. Improves workability.

[0011]

However, in the configuration of the conventional example described above, at the moment when the main body section 4 and the remote input / output section 5 are connected at the time of construction, the steady state of the remote input / output section 5 is set on the two-wire wiring 6, 7. Since the consumption current starts flowing, the current flow changes,
There is a possibility that the electric lock 1 may be operated unintentionally. Further, even when the state of the electric lock 1 is changed and the output voltage value on the two-wire wirings 6 and 7 is changed, the steady current consumption of the remote input / output unit 5 may change. Wiring 6, 7
A change may occur in the energizing current above, and the electric lock 1 may unintentionally operate. In this case, even if there is a change in the input voltage from the two-wire wirings 6 and 7 to the remote input / output unit 5, there is no problem as long as the steady current consumption of the remote input / output unit 5 does not change. However, there is a problem that the circuit configuration becomes complicated.

The present invention solves the above-mentioned problems of the prior art, and the electric lock operates unintentionally even when the current flowing through the two-wire wiring changes during construction or when the state of the electric lock changes. It is an object of the present invention to provide an electric lock control device that can prevent such a situation and improve the workability and reliability.

[0013]

In order to achieve the above object, an electric lock control device of the present invention is provided with a control means for controlling the electric lock and a state of the electric lock while an electric lock state signal is input. A main body having voltage output means for outputting a constant voltage value that differs depending on a signal onto the two-wire wiring, and current detection means for detecting a change in the energizing current on the two-wire wiring;
Voltage detecting means for detecting a voltage value between the two-wire wiring and current value determining means for determining a predetermined current according to the state of the operating portion are provided, and the predetermined current determined by the current value determining means is set to the above-mentioned 2 A remote input / output unit having an energizing unit for energizing the wire wiring, wherein the current value determining unit includes the remote input / output unit.
The current value that is different from the current consumption value of the entire power unit
The control means is provided with a judging section for judging the change value of the current inputted from the current detecting means, and the energizing current is decided by the current value deciding means.
Further , the electric lock is configured to be controlled only when the predetermined current value is reached.

In order to achieve the above object, the electric lock of the present invention
In the control device, the control means is provided by the voltage output means.
The elapsed time after changing the constant voltage value on the 2-wire wiring
It has a clocking means for clocking, and is clocked by the clocking means.
If the elapsed time is less than the specified time, the electric lock
It is configured so as not to perform control .

[0015]

According to the present invention having the above-described structure, the steady current consumption of the remote input / output unit and the energization current value of the energizing unit determined by the action of the current value determining unit are different, and the control unit of the main body unit is the judgment unit. The change of the input current from the current detection means is judged by the function of the current detection means, and the electric lock is locked and unlocked only when the current change value is due to the operation of the energizing means. Even if the energizing current on the two-wire wiring changes at the moment when the unit is connected to the two-wire wiring, this change value is the steady-state current value of the remote input / output unit, so the determination unit of the control means determines this. Therefore, the electric lock is not locked or unlocked.

Further, even if the control means changes the output voltage of the voltage output means by the function of the internal timekeeping portion, the electric lock is locked for a certain period of time even if the input current value from the current detection means changes. Since the unlocking operation is not performed and then the current change is newly detected, the state of the electric lock is changed, and the control means outputs the voltage of the voltage output means, that is, the 2-wire wiring to the remote input / output section. Even if the input voltage is changed and the current flowing through the two-wire wiring changes, the electric lock does not operate.

Voltage detection means 1 of remote input / output unit 5
Reference numeral 1 detects the voltage value between the wirings 6 and 7 and drives the display unit 13 of the remote control means 3 to display the voltage value, that is, the display according to the state of the electric lock 1.

When the user operates the operation unit 14 of the remote control means 3 to lock or unlock the electric lock 1, the operation unit 1
Reference numeral 4 outputs a command signal to the energizing means 12 of the remote input / output unit 5. The energizing means 12 receives this, and energizes the wirings 6 and 7 with a constant current having a value determined by the internal current value determining means 16. This current value is different from the current consumption value of the entire remote input / output unit 5. The current change detection means 10 of the main body portion 4 is such that the energization current on the wirings 6 and 7 is the energization means 1
The output of 2 detects the change and outputs a signal indicating the current change value to the control means 8. The control means 8 receives this signal, and if the current change value is determined by the energizing means 12 by the internal judging section 15, the electric lock 1 is driven to be locked or unlocked, and the current change value is determined by the energizing means 12. If not, control is not performed.

As described above, according to the above embodiment, the main body 4 outputs the state of the electric lock 1 in the form of a voltage value to the remote input / output unit 5, so that only the two-wire wirings 6 and 7 can be obtained. The display unit 13 can display a plurality of statuses such as locking, unlocking, and opening / closing of the door by using the same two-wire wiring 6, 7.
In addition to the conventional convenience that the operation of the remote control means 3 can be transmitted to the main body section 4 in the form of a change in the energization current value using the, the remote control means 3 can be operated by the current value determining means 16 in the energization means 12. Is transmitted to the main body portion 4 at a current value different from the consumption current value of the entire remote input / output portion 5, and the determination portion 15 provided inside the control means 8 in the main body portion 4 inputs it through the current detection means 10. The control means 8 drives the electric lock 1 only when the change value of the energizing current on the two-wire wirings 6 and 7 is the value of the energizing means 12, so that the main body portion 4 can be installed at the time of construction. When the remote input / output 5 is connected with the electric lock 1
Does not operate unintentionally, and safety and reliability can be improved.

Further, the current value of the energizing means 12 is determined by the current value deciding means 16, so that when a plurality of remote input / output units 5 are connected on the two-wire wirings 6 and 7, If there are simultaneous inputs to a plurality of operating units 14,
The change value of the energizing current on the two-wire wirings 6 and 7 is the current value determining means 1
It is a multiple of the value determined by 6.
Since the internal control means 8 does not drive the electric lock 1 based on the judgment of the internal judgment part 15, the state of the electric lock 1 changes against the user's intention when a plurality of operating parts are operated simultaneously. It will not happen and safety will be improved.

Next, a second embodiment of the present invention will be described. FIG. 2 is a block diagram showing an electric lock control device according to the second embodiment of the present invention.

At this time, since the input voltage of the remote input / output unit 5 changes, the energization current value on the two-wire wirings 6 and 7 changes unless the circuit configuration in the remote input / output unit 5 is a constant current circuit. The control means 8 in the main body portion 4 inputs this current change value via the current detection means 10, but the electric lock 1 is driven even if a current change is input during a fixed time period clocked by the internal timing portion 17. 2 is not done
Electric lock 1 at the moment when the output voltage value on the wires 6 and 7 changes
