Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic lock system that prevents people from leaving the house or going to bed without forgetting to turn on electrical equipment that could cause a fire.

In the past, people often forgot to turn on electrical appliances such as irons when they went out, leading to fires and other accidents.

In order to prevent such accidents from occurring, something like a display panel that can check the usage status of electrical equipment has been proposed, but if you forget to perform an autopsy when you go out, It is not possible to prevent such accidents from occurring.

In view of the current status of checking the usage status of electrical equipment as described above, the present invention aims to know whether or not unnecessary electrical equipment is in use when going out and locking the master lock installed at the entrance etc. The purpose of this design is to provide an electronic lock system that can disable the master lock if necessary under inconvenient conditions. A detection means attached to the outlet to detect whether an electrical device is connected to each outlet, and a detection means attached to the power input side of the electrical device to electrically detect whether or not power is being consumed. a determination unit that determines the state or power consumption state of each outlet based on the signal from the detection means and outputs a determination signal; A setting section that arbitrarily sets the state with an electric signal, and the signals supplied from the discriminating section and the setting section are sequentially compared to calculate whether or not the respective discriminating signals and the setting signals match. A comparison control circuit that outputs a signal to that effect when the two signals completely match, and a signal specifying the mismatched portion when the two signals do not match; and a comparison control circuit that receives input from the comparison control circuit. The present invention is characterized in that it comprises a master lock, and a control section comprising a display circuit for displaying the respective information, and an operation circuit for controlling locking of the master lock based on the output of the comparison control circuit.

Next, an example of implementation of the system of the present invention will be explained with reference to the drawings.

1 is an individual outlet C to which various electrical devices are connected
1 to Cn as the detection means S, here, as shown in Figure 2, the insertion plug 3
When the plug 3 is inserted, the switch 1 is made conductive by the actuating rod 4, and a signal is obtained at a discriminating section, which will be described later.If the plug 3 is pulled out, the switch 1 remains cut off. ing.

Reference numeral 5 denotes a meter relay serving as another detection means S2 inserted on the power input side of an electrical device other than the above-mentioned devices, for example, in the middle of the power cord 6, to directly introduce power from the indoor wiring etc. without going through the above-mentioned outlets C1 to Cn. Electrical equipment E1-E
n, and detects whether or not the device is in the on state based on the presence or absence of a current value appropriately set in the meter relay 5, and supplies an electrical signal to a determination section to be described later. .

(See FIG. 3) 7 electrically determines the state of each of the outlets C0 to Cn and the electric devices E1 to En by conducting or cutting off the detection means S1 and S2, and For example, in the discriminator unit that sequentially outputs
When the microswitch 1 or the meter relay 5 is in a conductive state, a ↓ signal is output, and if they are in a cut-off state, a 0 signal is output. It looks like this.

8 is each of the above-mentioned outlets C to Cn or each electric appliance E1 to
This is a setting section that allows you to arbitrarily set the desired state of En. Here, a signal of 0 indicates that the plug 3 is not inserted into each outlet C1 to Cn, and a signal of 1 indicates that the plug 3 is inserted. In addition, a signal of 0 can be set when there is no power supply current in each of the electrical devices E1 to En, and a signal of 1 can be set when the current value is as specified.

In addition, each outlet C1 to Cn or each electric device E1 to En
The combination of the state and the 0 or 1 signal is arbitrary, but it must be the same as the combination in the discriminator 1.

Reference numeral 9 indicates a discrimination signal 1 or 0 for each outlet C1 to Cn and each electric appliance E1 to En from the discrimination section 7, and a setting signal 1 or 0 for each object set in the setting section 8. While successively comparing, if the discrimination signal and the setting signal all match, a signal to that effect is sent.
If there is no match, a comparison control circuit 10 specifies the target and outputs a signal indicating that there is no match, and 10 is a comparison control circuit that lights up one indicator G based on the match signal from the comparison control circuit 9, indicating that there is no match signal. 11 is a coincidence signal of the comparison control circuit 9; if there is an output based on the output, one of the indicator lights N1 to Nn representing one of the outlets C1 to Cn or the electric appliances E1 to En turns on; 11 is a coincidence signal of the comparison control circuit 9; This is an operating circuit that outputs a lockable signal for the master lock Km, which will be described later, by the output of , and an unlockable signal for the master lock Km by outputting a mismatch signal. There is.

Thus, the master lock Km controlled by the operating circuit 11
For example, a type using an electromagnet is used for the locking signal, and a lockable signal activates the electromagnet of the lock, and a lockable signal uses a type that can prevent activation of the electromagnet.

It is assumed here that the master lock h is provided as an entrance lock.

The operation of an example of the system of the present invention configured as described above will be explained.

Now, when the entire system of the present invention is in operation and, for example, you are about to go out, each outlet C1 to C is connected to the setting section 8.
n and the desired state of each electrical device E1 to En are set in advance.

This setting determines which outlets C1 to Cn can be plugged in with the input plug of an electrical device, and which may lead to an inconvenient situation if the input plug remains inserted. It is carried out according to the content determined in advance according to each usage mode, and each electrical equipment E0
~En is also set in accordance with the predetermined contents in the same way as for the outlets. For example, if this setting section 8 is formed of a group of switches, each switch corresponding to each outlet or electrical device is set. Operate to set the above decision.

Note that the state that each outlet and electrical device should be in is different depending on the individual usage, for example, when going out or sleeping, so program patterns should be prepared in advance to suit these situations. From this point of view, if the setting section 8 is constructed in a magnetic input format, the program pattern can be provided in a so-called magnetic card format, which becomes even more convenient.

The setting signal from the setting section 8 is then input to the comparison control circuit 9 and stored therein.

Therefore, a person who is going to go out should exercise normal caution and check whether each outlet C1 to Cn or each electrical appliance E1 to En is in a suitable condition when going out, and then lock the master lock Km at the entrance. An attempt is made to lock the door, but the locking is controlled as follows.

That is, in the comparison control circuit 9 to which the setting signal is supplied from the setting section 8, each of the outlets C1 to Cn which should have been in a predetermined state by the inspection of the person who is going to go out.
Since the determination signal representing the actual state of each electrical device E1 to En is supplied from the determination unit I, this circuit 9 successively compares the setting signal and the determination signal to determine whether or not they all match. After performing a comparison calculation, if the discrimination signal and the setting signal all match, a matching signal is output to the display circuit 10 indicating that the first indicator light G should be lit, and the indicator light G is lit, and the master lock is activated. The operating circuit 11 of Km is turned on to enable the master lock Km to be locked.

On the other hand, if the circuit 9 determines that there is a mismatch between the discrimination signal and the setting signal, the comparison control circuit 9 identifies the mismatch and selects one of the other indicator lights N1 to Nn of the display circuit 10. At the same time, it outputs a discrepancy signal indicating that the master lock h should be turned on, turns off the operating circuit 11 of the master lock h, and specifies whether any of the outlets C1 to Cn or the electric devices E1 to En are in an inconvenient state. Display master lock Km
This makes it impossible to lock the door.

Therefore, a person who wants to go out can lock the master lock Km by checking the status of the indicator light on the display circuit 10, but here, it is possible to determine whether or not the master lock Km is locked without checking the indicator light. Since they are controlled by the operating circuit 11, there is almost no possibility that the outlets C1 to Cn or the electric appliances E1 to En will leave the house in an inconvenient state.

If the master lock Km cannot be locked, check the part that is in an inconvenient state using the indicator lights N1 to Nn,
Put that part in the desired state so that the master lock Km can be locked.

Further, in the embodiment, the master lock Km is provided as an entrance lock, but it may be provided as a lock separate from the entrance lock, the operation of which is controlled by the system of the present invention.

Since the present invention is as described above, even if you forget to turn off an electrical device when you go out, etc., you will know this when locking the master lock, and if necessary, you can disable the master lock. This is extremely useful for disaster prevention, as it can prevent fire accidents caused by forgetting to turn off electrical equipment.
