Description

[Detailed Description of the Invention] This invention relates to an electronic lock device using a remote control type digital switch.

The purpose of this invention is to memorize arbitrary numbers from among 16 different digital switches in the order in which they are arranged, and to release the electronic lock only when the number in the arranged order is pressed. The object of the present invention is to provide a device that allows

An example of this invention will be described below with reference to the accompanying drawings.

This idea can be broadly divided into four elements.

That is, a remote control type digital switch unit 1 having 16 input digital switches IDS from 0 to 9 and A, B, C, D, E, F, a reception control circuit 2 thereof, and a reception control circuit 2 of the reception control circuit 2. Output terminal O
It consists of an operation signal generation circuit 3 that generates an operation signal based on the output of an arbitrary selected terminal from the DT, and a malfunction prevention circuit 4 connected to other terminals that are not selected.

Nomoto control type digital switch unit 1
As described above, the hexadecimal-to-binary conversion circuit 5 connected to the 16 digital switches IDS converts the hexadecimal signal from the digital switch IDS into a binary signal, and then outputs the hexadecimal signal in the order in which it was input. decimal serial conversion circuit 6
According to the input order, the oscillation circuit 7 generates oscillation via the light emitting diode LED.

In this case, the hexadecimal-to-binary conversion circuit may be a code conversion circuit such as a hexadecimal-BCD code conversion circuit, which serially converts a code such as BCD and outputs the result.

On the other hand, the reception control circuit 2 receives binary signals a, l via a serial in-parallel output decoder (serial IN/parallel OUT decoder) 9 which outputs the serial binary signals inputted from the reception sensor 8 as parallel binary signals.
), c, and d are input to the binary-hexadecimal decoder 10.

Of course, in the case of a BCD code, it may be a code conversion circuit that serially inputs the BCD code, outputs the BCD code in parallel, and converts the BCD code with a decimal decoder.

The output terminal ODT of the binary-hexadecimal decoder 10 has 16 terminals arranged from 0 to 9 and from A to F, similar to the digital switch IDS of the remote control type digital switch unit 1.

Out of these 16 terminals, for example, 3.5,
7. Each inverter IVT in that order from the terminal of C.
Thyristor 5CR1, 5CR2, 5CR3゜5 through
Each gate of CR4 is connected.

The thyristors 5CR1 to 5CR4 are connected in series, and the cathode terminal of the final thyristor 5CR4 is connected to an operating part 11 such as a relay or solenoid and grounded.

That is, voltage Vcc from the power supply circuit is applied to the anode terminal of the first thyristor SCR, and each thyristor 5
The cathode terminals of CR1 to CR3 are grounded through resistors and connected to the anode terminal of the next stage.

3.5,7. Other terminals except each terminal of C, namely 1, 2,
4゜6.8,9,0. The A, B, D, E, and F terminals are each connected to a NAND circuit NAND1. An OR circuit OR is connected via NAND2, its output terminal is connected to the base terminal of the switching transistor Q, and the collector terminal of the transistor Q is connected to the gate of the first thyristor 5CR1 to form the malfunction prevention circuit 4. ing.

Next, we will discuss the operation of the electronic lock device of the present invention having such a structure. First, when the combination number selected from the 16 position key switches is 3.5, 7°C,
First, follow the order of 3. of the digital switch IDS.
5,7. Press C.

These input hexadecimal signals are the following hexadecimal -
After being converted into a binary signal by the binary conversion circuit 5, the oscillation circuit 7 converts the signal into a serial binary signal according to the input order.
is output from.

The serial binary signal inputted by the receiving sensor 8 is converted into a parallel binary signal and inputted as a binary signal to the next binary-hexadecimal decoder 10, where it is converted to a hexadecimal signal and 16 Output terminal O~9. Among A-F, 3, 5, 7. Turn on C.

That is, 3.5, 7. The signal output from the output terminal of C at a low level is first converted from the output terminal of C to a high level by an inverter IVT to open the gate of the first thyristor 5CR1.

That is, the voltage Vcc is applied to the anode of the next thyristor 5CR2 by turning on the thyristor 5CR1, and
The signal turns on the thyristor 5CR2 for the first time.

Thus, by sequentially turning on the gate of thyristor 5CR3 and making thyristors 5CR1 to 5CR4 conductive, operating section 11 such as a relay or solenoid is driven.

At this time, if you press another number instead of C after pressing up to 3 and 5.7, even if the thyristor 5CR3 is conductive, the next thyristor 5CR4 will be disconnected, and the operating part 11 will not operate, and the other numbers will not operate. Since the output terminal of the number turns on the NAND circuit NAND or NAND2 and operates the transistor Q via the OR gate, the gate of thyristor 5CR1 is turned off by grounding the emitter, and all the thyristors are turned off. It will stop working completely.

Furthermore, it is easy to replace the thyristor with a semiconductor switching element such as a triac.

As described above, the present invention serially encodes and oscillates a combination selected from a plurality of hexadecimal digital switch numbers, converts the binary signal into the original digital number after receiving it, and converts it into a switching element. The device is made sequentially conductive so that the operating part is activated only in that combination, and remains inactive even when other numbers are pressed. Therefore, various electronic locks can be activated with a code unique to the user. For example, if it is used in a relay for a car alarm buzzer or a locking solenoid for a safe, a locking means that cannot be activated by other means can be obtained.

By the way, there are 43 combinations of selecting 4 buttons from 16 buttons.
There are 680 types, and by increasing the number of these switches, many combinations can be obtained, which is an excellent effect.
