Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless burglar alarm device suitable for preventing theft of valuables such as jewelry and precious metals.

[0002]

2. Description of the Related Art A conventional burglar alarm device includes a switch section whose open contact is closed by stepping on it, a detection section for detecting the state of the contact of the switch section, and a signal line connecting the switch section and the detection section. It is configured. The switch portion is composed of two spring members plated with a metal such as copper, an insulating support member for arranging these spring members so as to face each other, and an insulating covering member for covering the surroundings thereof. Each of the spring members and the detection unit are connected by a signal line. Then, when the switch portion is stepped on, the two spring members come into contact with each other, whereby an electric current flows and an alarm device such as a buzzer provided in the detection portion sounds.

The switch section is generally installed around a target noble metal, and particularly for a heavy object such as a Buddha statue, the switch section is installed under the switch and the contacts are closed by the weight. I am trying. In this case, when the Buddha image is lifted, the contact of the switch portion is opened, and therefore when this state is detected, the abnormality is notified.

[0004]

However, the above-mentioned conventional theft alarm device has the following problems. That is, when it is used for crime prevention of a valuable Buddhist image such as a Buddhist statue, the weight is constantly applied, so that the contact of the switch portion may not be immediately opened in the event of an abnormality, resulting in low reliability. In addition, it is difficult to use for valuables that are heavy enough to lose the restoring force of the insulating covering member of the switch, and if the switch is processed according to the size of the valuables. I won't. Furthermore, wiring to valuables is necessary, and especially when there are many valuables, it is necessary to perform wiring corresponding to the number.

Therefore, the present invention provides high detection accuracy,
Moreover, it is an object of the present invention to provide a wireless theft alarm device that is not affected by the weight and shape of valuables to be crime-prevented and does not require wiring corresponding to the number of valuables.

[0006]

In order to achieve the above object, a wireless burglar alarm device according to the present invention is a wireless burglar alarm device comprising a detecting section for detecting burglary and an alarm section separate from the detecting section. A theft alarm device, wherein the detection unit includes a detection unit that detects the presence or absence of the article, and a transmission unit that transmits the theft information when the article is lost, and the alarm unit outputs the theft information. It is characterized by comprising a receiving unit for receiving and an alarm unit alarm generating unit for generating an alarm when the theft information is received by the receiving unit.

In a preferred embodiment, a cuboid is formed into a pedestal, and a recess having an area smaller than the bottom area of the article is formed in a part of the upper portion of the pedestal. The pedestal is provided in the recess of the pedestal. A table that is thinner than the depth,
An elastic member that supports the table so that the upper surface thereof protrudes above the upper surface of the pedestal, and the detection unit includes:
The stolen information is transmitted when the upper surface of the table is located above the upper surface of the pedestal.

Further, the detecting means detects that the pedestal has been lifted, the detection unit alarm generating means issues an alarm when the pedestal is lifted, and the transmitting means, The stolen information is transmitted when the pedestal is lifted. Further, the detection unit has a theft detection stopping means for stopping the theft detection for a predetermined time after the warning start setting is performed.

[0009]

According to the present invention, a detection section for detecting theft and an alarm section for issuing an alarm when the theft is detected are separately provided, and the detection section is provided when an article such as a valuable item is removed. The theft information is transmitted, and the alarm unit receives the theft information transmitted from the detection unit and issues an alarm. When the detection unit is incorporated into the pedestal on which the Buddha image or the like is placed, the theft information is transmitted when the Buddha image or the like on the pedestal disappears. Further, the detection unit alarm generation means is provided in the detection unit to transmit the theft information and generate an alarm.

When a Buddhist image or the like is placed on the pedestal, the table provided on the pedestal sinks, and when the upper surface of the table is flush with the upper surface of the pedestal, the sinking stops. At this time, most of the weight of the Buddha image is added to the pedestal itself. If you lift a Buddha statue from this state, the table will rise. When the table rises, theft detection is performed, the theft information is transmitted, and an alarm is generated. Even when the Buddha image is lifted together with the pedestal, the theft is detected, the theft information is transmitted, and an alarm is issued. Further, when the detection unit is provided with the theft detection stop means, the theft detection stop means stops the theft detection function of the detection unit for a predetermined time after the warning start setting is made.

Therefore, since the detection unit and the alarm unit are wirelessly connected to each other, no wiring is required between them. Further, since the valuables are indirectly detected, the weight and shape of the valuables are not affected, and higher reliability can be obtained as compared with the case where the switch section is placed under the valuables. Further, by stopping the theft detection function of the detection unit for a predetermined time after the warning start setting is performed, the detection unit can be incorporated in the pedestal or the like after the warning start setting is performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a detection unit 18 of an embodiment of a wireless theft alarm device according to the present invention. 2 is a perspective view showing the appearance of a pedestal 20 on which a Buddhist image is placed, which is an application example of the wireless burglar alarm device of this embodiment, and FIG. 3 is a pedestal 2
0 is a perspective view showing a state in which a Buddhist image 110 is placed on the surface 0, and FIG. 4 is a vertical sectional view showing the structure of the pedestal 20. In FIG. 1, reference numeral 1 denotes a CPU, which outputs the limit switches 2 and 3, the warning start / cancel switch 4, and the ROM 5
The detection unit 18 is controlled in accordance with the program written in. As is well known, the limit switches 2 and 3 are composed of a switch body (not shown) and an actuator for turning on / off the switch of the switch body.
The alert start / cancel switch 4 is a rotary changeover switch.

One end of each of the limit switches 3 and 4 is commonly connected and grounded. The other end is connected to the signal input end of the CPU 1 and is pulled up by resistors R and R. Therefore, when the limit switches 3 and 4 are turned on, the signal input terminal of the CPU 1
It goes to "L" level and goes to "H" level when turned off. The neutral end c of the warning start / release switch 4 is connected to the signal input end of the CPU 1, and the fixed end a is pulled up by the resistor R. Further, the fixed end b is grounded.
Therefore, when the neutral end c of the warning start / cancel switch 4 is set to the fixed end a, the signal input end of the CPU 1 becomes "H" level, and when it is set to the fixed end b, it becomes "L" level.

Reference numeral 6 denotes a transmission circuit which transmits alarm information on a carrier wave of a predetermined frequency under the control of the CPU 1. Further, the transmission circuit 6 is under the control of the CPU 1,
The operation confirmation signal is transmitted periodically. This operation confirmation signal is for notifying the alarm unit 34, which will be described later, whether or not the normal operation is being performed. It goes without saying that the transmission power of the transmission circuit 6 is suppressed within the range specified by the Radio Law.

Reference numeral 7 denotes an alarm generation circuit which, under the control of the CPU 1, generates an alarm sound from a speaker 8 and causes an LED (light emitting diode) 9 to blink. Reference numeral 10 denotes a power supply circuit having a battery (not shown) and the like, which has a function of detecting the power supply voltage of the battery and supplies a signal indicating a voltage drop to the CPU 1 when the voltage level becomes equal to or lower than a predetermined value.
Here, when the CPU 1 inputs a signal indicating a voltage drop from the power supply circuit 10, the CPU 11 turns on the LED 11. A power switch 12 is connected in series to the output of the power circuit 10.
The alarm generation circuit 7, the speaker 8 and the LED 9 constitute a detector alarm generation means 17.

Next, in FIG. 2, the pedestal 20 is formed in a regular hexagonal column shape, and a recess 20A is formed in the center thereof. A table 21 that is swingably supported in the vertical direction is provided in the recess 20A. This table 21
Has an area smaller than the bottom area of the Buddha image 110, and has a thickness slightly smaller than the length of the recess 20A of the pedestal 20 in the depth direction. In this case, by making the area of the table 21 smaller than the bottom area of the Buddhist image 110, the load of the Buddhist image 110 is almost not applied to the table 21, thereby preventing the limit switch 2 from being broken by the direct load. Also, table 21
The thickness of the table 21 is made slightly shorter than the length of the recess 20A of the pedestal 20 in the depth direction, so that the upper surface of the table 21 can be aligned with the upper surface of the pedestal 20 when the Buddha image 110 is placed. At this time, the actuator of the limit switch 2 is pushed toward the switch body side and is turned on. The mounting of the limit switch 2 will be described below.

FIG. 4 is a vertical sectional view of FIG. 2. As shown in FIG. 4, a table 21 projects from the upper surface of the pedestal 20 and is supported by spring columns 22 and 23. Also, the limit switch 2 attaches the actuator to the base 2
It is attached so as to project from the bottom surface of the recess 20A of 0. Further, the limit switch 3 is attached so that its actuator projects from the bottom surface of the pedestal 20.

The limit switch 2 has a pedestal 20 and a Buddha image 11
0 (in this case, the Buddha image 110, needless to say, is not limited to this) is turned on, and the limit switch 3 is turned on by placing the pedestal 20 on the floor or the like. . A lid 20B is opened on the bottom of the pedestal 20, and the detection unit 18 is taken in and out by opening the lid 20B. Also, the pedestal 20
An alarm start / release switch 4 is attached to the bottom of the.

Next, FIG. 5 is a block diagram showing the structure of the alarm unit 34 of the wireless theft alarm device of this embodiment. In the figure, reference numeral 26 is a CPU, which controls the alarm unit 34 according to a program written in the ROM 27. 28 is a warning sound reset switch, the output of which is input to the CPU 26. A receiving circuit 29 receives the alarm information transmitted from the detecting unit 18. When the receiving circuit 29 receives the alarm information, it outputs the result to the bus BUS.
Print on top. Reference numeral 30 denotes an alarm generation circuit, which is the CPU 26
An alarm signal is output under the control of. Reference numeral 31 is a speaker and 32 is an LED. The alarm generation circuit 30, the speaker 31, and the LED 32 constitute alarm unit alarm generation means 33.

In the wireless theft alarm device thus constructed, the operation of the detector 18 will be described with reference to the flowchart shown in FIG. The operation of the alarm unit 34 will be described with reference to the flowchart shown in FIG. In FIG. 6, first, when the power is turned on,
In step S10, the CPU 1 determines whether the warning start setting has been made. That is, the output of the warning start / cancel switch 4 is fetched, the level thereof is judged, and if the output is the "H" level, it is judged that the warning start has been set, and the process proceeds to step S12 to set the "L" level. If there is, it is determined that the warning release setting has been made, and this step S10 is repeated.

In step S12, it is determined whether the limit switch 2 is off. That is,
The output of the limit switch 2 is fetched and the level thereof is judged. If the output is the "L" level, it is judged that the limit switch 2 is in the ON state (no abnormality), the process proceeds to step S14, and "H" If it is a level, it is determined that the limit switch 2 is in the off state (abnormal), and the process proceeds to step S16. When the process proceeds to step S14, the output of the limit switch 3 is fetched and its level is determined. If the output is the "L" level, it is determined that the limit switch 3 is in the ON state (no abnormality) and the step S12 is performed. Returning to step S16, if the level is "H", it is determined that the limit switch 3 is in the off state (abnormal), and the process proceeds to step S16.

If the limit switch 2 is off or the limit switch 3 is off, alarm information is transmitted in step S16. That is, the CPU 1 supplies a control signal for generating an alarm to the transmission circuit 6 to transmit the alarm information. Here, when the Buddha image 110 is lifted from the pedestal 20, the limit switch 2 is turned off and alarm information is transmitted. Further, when the Buddha image 110 is lifted for each pedestal 20, the limit switch 3
Turns off and alarm information is transmitted in the same manner.

After transmitting the alarm information, the CPU 1 controls the alarm generation circuit 7 to generate an alarm sound and blink the LED 9 in step S18.
As a result, an alarm sound is generated from the speaker 8 and the LED 9 blinks. Next, the CPU 1 executes step S20.
It is judged whether or not the warning release is set in. That is,
The output of the warning start / cancel switch 4 is fetched, the level thereof is judged, and if it is the "L" level, it is judged that the warning cancel setting has been made, and in step S22, generation of an alarm sound and blinking of light are stopped. On the other hand, if the output of the warning start / cancel switch 4 is at the "H" level, the alarm sound is generated and the light continues to blink.

Next, referring to FIG. 7, when the power is first turned on, the CPU 26 determines in step S30 whether or not the warning information is output from the receiving circuit 29. If it is determined that the warning information is not output, this step S30
repeat. On the other hand, if it is determined that the alarm information has been output, an alarm is generated in step S32. That is, the CPU 26 causes the alarm generation circuit 30 to respond to the speaker 3
The control for generating an alarm sound from 1 and blinking the LED 32 is performed. The generation of the alarm sound and the blinking of the light continue until the alarm reset switch 28 is pressed.

After supplying the control signal to the alarm generation circuit 30, the CPU 26 determines in step S34 whether or not the alarm reset switch 28 has been pressed. If it is determined in this determination that the alarm reset switch 28 has not been pressed, this step S34 is repeated, and if it is determined that it has been pressed, the process proceeds to step S36 to stop the generation of an alarm sound and the blinking of light.

In the above embodiment, the battery is used as the power source of the detecting section 18, but a commercial power source (100V AC) can be used. When a commercial power supply is used, it is advisable to output a power-off signal when a power failure occurs. Further, in the above embodiment, the warning start / cancel switch 4 is attached to the pedestal 20, but when it is attached to the detection unit 18 itself, a timer function is provided so that the warning start state is set after a certain period of time after the warning start setting is performed. It is good to provide. That is,
Stop the theft detection for a certain period of time after the start of warning. As a result, it becomes possible to put the detection unit 18 into the pedestal 20 after setting the alarm start state. In this case, the timer function corresponds to the theft detection stopping means.

Further, in the above-mentioned embodiment, when the limit switches 2 and 3 are turned off, an alarm is issued immediately, but an alarm may be issued after a certain period of time after they are turned off. good. As a result, it becomes possible to replace or clean the battery within a certain time.

Further, in the above embodiment, the area of the table 21 of the pedestal 20 is made smaller than the bottom area of the Buddha image 110 so that the total load is not applied to the table 21, but as shown in FIG. It is also possible to form a concave portion 37A having a smaller diameter at the lower side than that at the upper side so that the table 38 is locked midway. In this case, since the lower surface of the table 38 does not reach the actuator of the limit switch 2, the convex portion 38A is formed on the lower surface of the table 38 as illustrated. Reference numeral 39 in this figure is a vase. on the other hand,
In the case of a lightweight one such as a ring, as shown in FIG.
You may make it support by 3. In this case, since the structure can be seen from the outside, it may be covered with the cut 44 or the like. Reference numeral 45 in this figure is a ring.

Further, although the limit switches 2 and 3 are provided as the detecting means in the above-mentioned embodiment, an electric type device such as a photo coupler may be provided in addition to the mechanical type. Further, in the above embodiment, the limit switch 3 is provided below the pedestals 20, 37 and 42, but it is not always necessary.

[0030]

According to the present invention, the detecting section for detecting the theft and the alarm section for issuing an alarm when the theft detection is performed by the detecting section are wirelessly connected to each other. Becomes unnecessary. Further, since the valuables are indirectly detected, the weight and shape of the valuables are not affected, and higher reliability can be obtained as compared with the case where the switch section is placed under the valuables. In addition, by stopping the theft detection function of the detection unit for a predetermined time after the warning start setting is made,
The detection unit can be incorporated into a pedestal or the like after setting the warning start.
