Description

  The present invention relates to a crime prevention alarm device that prevents a vehicle from being rough and a crop theft from being detected by a vibration detection function of a vibration sensor.

  As a conventional automobile anti-theft device, the mounting of an immobilizer device has generally become widespread, and other devices such as a handle lock have been put into practical use (Patent Document 1).

  In addition, for crime prevention such as vandalism, a device has been proposed in which an immobilizer device has a built-in vibration sensor that sounds an alarm sound when vibration for a certain period of time is detected (Patent Document 2).

  In addition, there has been proposed a device that issues a warning by sounding a horn of a car when a vibration sensor detects vibration, or generating a warning sound from a strobe, a rotating lamp, and a speaker (Patent Document 3).

  Furthermore, there has also been proposed a configuration in which an infrared sensor is provided in addition to the vibration sensor so that a warning sound is emitted when a human body is detected by the infrared sensor after vibration detection by the vibration sensor (Patent Document 4).

Japanese Patent Laid-Open No. 8-30873 (refer to column “0019” in FIG. 1) Japanese Patent Application Laid-Open No. 2004-276760 (see “Description” column, FIG. 6) JP-A-8-108826 (refer to the description "0017" column, "0018" column, FIG. 1) JP 2004-189132 A (refer to the description “0019” column, “0020” column, “0024” column, FIG. 1 and FIG. 2)

  By the way, even in the case of an immobilizer device or a car with a handle lock as in Patent Document 1, if the thief can visually check the security equipment, the security equipment is removed or the vehicle itself is towed, There were problems such as not being activated.

  Moreover, since the immobilizer device like patent document 2 is previously incorporated in the vehicle by the manufacturer side, even if it can respond to a new vehicle, the subject that it is difficult to retrofit to the vehicle already owned There is.

  In addition, the device such as Patent Document 3 can be retrofitted, but when the device is installed in the vehicle, the connection cord to the battery of the vehicle, the connection cord to the room lamp, the key switch to the ACC The main unit must be connected to a connection cord, a connection cord to a vehicle horn, an earth cord, etc., and there is a problem that installation of the device itself on the vehicle is not easy for an amateur.

  Moreover, although the apparatus like patent document 4 is comparatively easy to install in a vehicle, it is necessary to use two types of sensors, a vibration sensor and an infrared sensor, as a security sensor, and two different characteristics. Since it is necessary to reliably detect the intrusion of a suspicious person by a sensor, there is a problem that the control becomes complicated and the apparatus price becomes expensive.

  The present invention has been made in view of the above-described conventional problems, and provides a crime prevention alarm device that can exhibit a high crime prevention effect with a simple configuration and at a low price, and that can be easily installed in a vehicle even by an amateur. The purpose is to provide.

  With this configuration, for example, when used as a security alarm device for an automobile, the main body is placed in a suitable place in the automobile and the speaker is installed, for example, with the outside facing the inside of the front grill. It is only necessary to connect with the connector part. The control means of the main body repeatedly performs the sound emitting operation of the warning sound signal only when the output signal level exceeding the threshold value of the vibration sensor continues for a predetermined time or more. Therefore, it is possible to realize an effective crime prevention alarm device that is extremely simple to install and has few malfunctions with only the vibration sensor.

Second, in a security alarm device that issues an alarm based on vibration detection of a vibration sensor built in the main body, the main body includes a battery that supplies power to each part in the main body, and a warning sound that is previously composed of human words. Voice memory, threshold setting means for setting an output signal level equal to or higher than a predetermined level of the vibration sensor as a threshold, the threshold and the output signal level of the vibration sensor are compared, and the threshold Comparing means for outputting a detection signal when the above output signal level continues for a predetermined time or more, and a warning sound composed of human words by reading out the sound data from the sound memory based on the detection signal from the comparing means A control means for generating a signal, and a carrier wave of a specific frequency is modulated by the warning sound signal generated by the control means, and the carrier wave is wirelessly transmitted.

The control means of the main body is constituted by a security alarm device characterized by repeatedly sending the warning sound signal to the transmitting means a plurality of times.

  If comprised in this way, since a speaker housing | casing is a different body from a main body, it can implement | achieve an effective crime prevention alarm apparatus with a high freedom degree of installation of a speaker housing | casing, although it is a simple structure.

  Thirdly, the warning voice signal is voice data in which a combination of voice data composed of words for calling attention to surrounding people and voice data composed of words for prompting surrounding people to contact the police is one cycle. It is comprised by the security alarm device as described in said 1 or 2 characterized by comprising.

  Fourthly, the control means comprises the security alarm device according to the third aspect, wherein the one-cycle warning sound signal is transmitted a plurality of times.

  Therefore, in order to use the warning voice which makes the voice data which consists of the word which calls the above-mentioned warning and the voice data which consists of the word which calls the police indicate 1 cycle, it is compared with the alarm sound such as a simple horn. Can increase the alerting effect.

  Fifth, the comparison means outputs the detection signal when the output signal level equal to or higher than the threshold value continues for 5 seconds or more, according to any one of the first to fourth aspects, It consists of a security alarm device.

  Therefore, since a warning operation is performed for the first time when a large vibration of a predetermined level or more continues for 5 seconds or more, a highly accurate vibration detection operation can be performed despite the simple configuration of only the vibration sensor. .

Sixth, a plurality of speaker housings provided with receiving means capable of receiving the same carrier wave of the specific frequency and demodulating and detecting the warning sound signal are provided for one main body.

Seventh, there are provided a plurality of the main bodies, receiving means capable of demodulating and detecting the warning audio signal by setting all the specific frequencies of the carrier waves transmitted from the main body to the same frequency and receiving the carrier waves of the specific frequencies. One or a plurality of speaker housings are provided for the plurality of main bodies, and the security alarm device according to the second aspect is configured.

  Therefore, if there are multiple areas where security alerts are required, installing a main unit for each area makes it very easy to create an effective security alert network over a wide area, with a very simple configuration. Can be configured.

Eighth, with disposing the body in the car of the automobile, the first, characterized in that the speaker is obtained by installing toward the sound emitting part of an automobile outer front grille inside of the motor vehicle or It is comprised by the crime prevention alarm apparatus of 2 described.

  Ninth, the main body is fixed to the entrance door of the greenhouse, and a plurality of the speaker housings are arranged along the longitudinal direction of the greenhouse with the sound emission part of the speakers facing the outside of the greenhouse. The skeleton pipe portion is fixed at predetermined intervals, and is constituted by the security alarm device according to the sixth aspect.

  Tenth, a plurality of the main bodies are provided, and each of the main bodies is fixed to the trunk or branch of the tree in the orchard, and one speaker housing is connected to the transmission radio wave from the main body in the orchard. The security alarm device according to the seventh aspect, which is installed in a reception area.

As described above, the present invention uses only the vibration sensor built in the main body and performs an alarm operation only when the continuation of vibration at a predetermined level or more and a predetermined time or more is detected. However, it is possible to realize an effective crime prevention alarm device with few malfunctions while being very simple and the installation method to the alert object is very simple.

In addition , the main body is driven by a battery such as a dry cell battery, so there is no need to use the battery of the automobile body, and there is no need to connect to the electrical system of other automobiles. It is extremely easy to set up an effective security alarm device with few malfunctions, even for amateurs who are not familiar with the vehicle's electrical system. it can.

  Also, without using the buzzer sound used in the past or the horn of an automobile, the warning sound consisting of human words with one cycle of words that call attention and words that call the police is emitted multiple times. It is possible to dramatically increase the degree of recognition of a warning for people and to improve the degree of danger recognition for a warning against a thief.

Moreover, the warning sound by a human language is made into 1 cycle, and the alerting effect with respect to a warning sound can be heightened by repeating such a 1-cycle warning sound.
Also, if the main body with the power switch turned on is placed in the vehicle, the vibration sensor detects the vibration of closing the door because the owner of the vehicle is already in a warning state when leaving the vehicle and closing the door. Although the output signal is input to the comparison circuit, the vibration when the door is closed does not continue for, for example, 5 seconds or more, so that the signal level falls below the threshold before the timer finishes timing for 5 seconds. Therefore, the comparison circuit does not output a detection signal. In this way, even if the vehicle owner turns on the power switch, closes the door, and exits the vehicle, the warning sound does not sound.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is an overall configuration diagram showing an external configuration of a security alarm device (first embodiment) according to the present invention. In the figure, a main body 1 is formed of a resin such as plastic and has a size of a cigarette case. The main body 1 and the external speaker 2 are connected by a long connection cord 3 (the length of the connection cord 3 is 3 m to 5 m, for example). The connection cord 3 of the speaker 2 has a pin plug 3a at its end, and is detachable from the pin jack 3b of the main body 1. The pin plug 3a and the pin jack 3b are referred to as a connector portion 3 '. Therefore, for example, when the main body 1 is installed inside the automobile, the speaker 2 is installed away from the installation place of the main body 1, for example, inside the radiator grille of the automobile front, and so on (see FIG. 14). The pin plug 3a of the connection cord 3 can be drawn into the automobile and easily connected to the pin jack 3b of the main body 1.

  The main body 1 incorporates a battery 12 (see FIG. 2), and the main body 1 of the apparatus is turned on and off by a power switch 4 provided on the front surface of the main body 1. Reference numeral 5 denotes an indicator composed of an LED or the like indicating the remaining battery level of the power battery. For example, an AA battery is preferably used for the battery 12 of the main body 1.

  FIG. 2 shows an electrical configuration of the crime prevention device according to the present invention. In the figure, reference numeral 6 denotes a vibration sensor, which uses a piezoelectric ceramic device or the like, and always senses vibration when the main body 1 is powered on. The vibration sensor 6 is connected to a comparison circuit 7 a of the vibration sensor detection unit 7. The vibration sensor 6 outputs a signal having a level corresponding to the magnitude of the vibration when detecting vibration in any of the xyz directions at the main body installation position (see FIG. 3A).

  Reference numeral 7 denotes a vibration sensor detection unit, which is a comparison circuit 7a to which the vibration sensor 6 is connected, and a threshold setting circuit (FIG. 3A) that is connected to the comparison circuit 7a and sets a vibration detection level (threshold value) L1. (Threshold setting means) 7b, a timer 7c connected to the comparison circuit 7a for detecting an on-delay time (FIG. 3B), and a vibration detection signal (to the control circuit 9 based on an output signal from the comparison circuit 7a). A detection signal generation circuit 7d for transmitting a detection signal).

  The comparison circuit 7a compares a signal level (output signal level) proportional to the magnitude of vibration output from the vibration sensor 6 with the set threshold value L1 set by the threshold setting circuit 7b, and the output signal level is When the threshold value L1 is exceeded, the timer 7c is actuated to start measuring time for 5 seconds (predetermined time), and when the output signal level exceeds the threshold value L1 for 5 seconds or more, that is, strong vibration exceeding the predetermined level is 5 When it continues for more than 2 seconds, a detection signal is sent to the detection signal generation circuit 7d in the next stage. Based on the input of the detection signal, the detection signal generation circuit 7d sends a pulse-like vibration detection signal (detection signal (FIG. 3B)) to the audio signal generation circuit 9. The comparison circuit 7a. The detection signal generation circuit 7d constitutes a comparison means.

  Therefore, as shown in FIG. 3 (a) t1, when the output signal level equal to or higher than the threshold value L1 of the vibration sensor 6 does not continue for 5 seconds, it is determined that the theft is not a car theft and the detection signal is not transmitted. . Therefore, in this case, no alarm operation is performed. This is because when the door is closed after the security alarm device body 1 is placed in an automobile and set in a warning state, vibration at the time of closing the door is generated, but this vibration usually falls within 5 seconds. This is to prevent malfunction due to vibration caused by the owner of the automobile closing the door.

  The vibration level detection time “5 seconds” (so-called on-delay time) can be arbitrarily changed, and can be set to a shorter time of 3 to 4 seconds and a longer time of 6 to 10 seconds. However, considering the detection accuracy while taking into account the time when the vehicle owner leaves the vehicle as described above, it is preferably about 5 to 5 seconds.

  Reference numeral 9 denotes a control circuit (control means), which uses a one-chip microcomputer or the like with a voice synthesis function such as a D / A converter. The operation procedure of the operation program stored in the ROM of the control circuit 9 is shown in FIG. The control circuit 9 is normally in a warning state when the power is turned on (FIG. 4P1). When the vibration detection signal is input from the detection signal generation circuit 7d in this state, the digital sound is output from the sound memory 10 based on the input. Data is read (read) (FIGS. 4P2 and P3), the digital signal is converted into an analog audio signal (warning audio signal) by a built-in D / A converter (FIG. 4P4), and then sent to the amplifier circuit 11 at the next stage. This operation is repeated a plurality of times (in this embodiment, twice) (FIGS. 4P5 to P7). Therefore, by the operation of the control circuit 9, one cycle of alarm sound such as “Drobo! Dorobo! Call someone police! Call someone police!” Is repeated several times (twice in this embodiment). Will be output. If the power is not turned off, the process returns to the alert state. If the power is turned off, the process ends (P8 in FIG. 4).

  The voice memory 10 stores digital voice data. In the memory 10, human words such as “Drobo! Dorobo! Call someone police! Call someone police!” (1 Cycle) is used for digital recording. As shown in FIG. 15, the warning voice signal includes voice data D1 (for example, “Drobo! Drobo!”, Etc.) composed of words that call attention to surrounding people, and prompts the surrounding people to contact the police. Voice data consisting of words combined with voice data D2 (for example, "Please call someone police! Call someone police!") Is a voice data that is recorded and digitized by human voice. Is preferably used as audio data.

  Reference numeral 11 denotes an amplifier circuit (amplifying means) which amplifies the audio signal sent from the control circuit 9 to an appropriate volume and sends it to the speaker 2 connected by the connection cord 3 via the connector portion 3 '. The battery 12 supplies power to the main parts of the present apparatus such as the control circuit 9, the amplifier circuit 11, and the vibration sensor detection unit 7 when the power switch 4 is turned on.

  Since the present invention is configured as described above, when the security alarm device according to the present invention is set in an automobile, the main body 1 is first placed in an inconspicuous place such as under the seat in the vehicle. . At this time, since connection between the main body 1 and the electric system connection cord in the automobile is not required at all, the main body 1 may be simply placed under a seat.

  On the other hand, the speaker 2 is set on the back side of the front grille of the automobile and the sound emission part is directed to the outside of the vehicle (see FIG. 14), the connection cord 3 is pulled into the vehicle, and the pin plug 3a at one end thereof is placed under the seat. It connects with the pin jack 3b of the said main body 1 mounted. Thereafter, the power switch 4 of the main body 1 may be turned on to exit the automobile. The speaker 2 can be fixed by any method, but an elastic rubber band or the like can be used.

  When the power switch 4 is turned on, power is supplied from the battery 12 to each part of the apparatus, so that each part in the main body including the vibration sensor 6 is set in an operating state and enters a warning state. Further, the control circuit 9 also enters a warning state based on the supply of the power (P1 in FIG. 4).

  Accordingly, when the owner of the vehicle leaves the vehicle and closes the door, the vehicle is already in a warning state. Therefore, the vibration sensor 6 detects the vibration of closing the door, and the output signal is input to the comparison circuit 7a. At this time, if the output signal level exceeds the threshold L1, the comparison circuit 7a starts measuring time for 5 seconds based on the timer 7c (FIG. 3A). However, since the vibration when the door is closed does not continue for more than 5 seconds, the signal level falls below the threshold value L1 before the timer 7c finishes timing for 5 seconds (see t1 in FIG. 3 (a)). Therefore, the comparison circuit 7a does not output a detection signal. In this way, even if the vehicle owner turns on the power switch 4 to close the door and exit the vehicle, no warning sound is produced.

  Next, when the car vibrates due to a thief such as a rough car opening the door, etc., the car vibrates for more than 5 seconds due to the thief opening the door and entering the car. The level continues for more than 5 seconds beyond the threshold L1. Alternatively, even if the vehicle can enter the vehicle, the vehicle vibrates due to, for example, the inside of the vehicle being colored, so that the output signal level of the vibration sensor 6 exceeds the threshold value L1 and continues for 5 seconds or more. In this case, the comparison circuit 7a outputs a detection signal to the detection signal generation circuit 7d (FIG. 3 (a)).

  The detection signal generation circuit 7d sends a vibration detection signal to the control circuit 9 based on the input of the detection signal (FIG. 3B). The control circuit 9 reads audio data from the audio memory 10 based on the input of the vibration detection signal (FIGS. 4P2 and P3), converts the audio data into an analog audio signal (FIG. 4P4), and converts the converted analog audio signal. (Warning audio signal) is sent to the amplifier circuit 11 (P5 in FIG. 4).

  The amplifier circuit 11 amplifies the analog audio signal and sends it to the speaker 2. Then, a loud warning sound is emitted from the front grille of the automobile toward the outside from the speaker 2 "Drobo! Dorobo! Call someone police! Call someone police!"

  When the control circuit 9 detects the end of the audio signal transmission (FIG. 4P6), it detects whether or not the audio signal transmission operation has been completed twice (FIG. 4P7). Therefore, the operations in steps P3 to P6 are repeated again, and the audio signal is sent to the amplifier circuit 11 again. Accordingly, the speaker 2 repeatedly emits a one-cycle warning sound with words similar to the human voice of “Drobo! Dorobo! Call someone police! Call someone police!”.

  Since this warning sound is emitted toward the outside of the vehicle from the speaker 2 installed in the front grill of the vehicle as described above (FIG. 14), it is extremely effective for an unspecified number of people outside the vehicle. A warning can be issued. Of course, the setting of the number of times of sending out the warning sound can be changed, and may be three or more. Also, the warning voice is based on a voice that makes one cycle a word that calls attention to the people around you (for example, “Drobo!”) And a word that calls the police (for example, “Please call the police!”). Thus, since the warning sound is repeatedly emitted a plurality of times, the alerting effect to people around the car can be greatly enhanced.

  Thereafter, the control circuit 9 detects whether or not the power switch 4 has been turned off. If the power switch 4 has not been turned off, the control circuit 9 returns to step P1 again to enter a warning state (P8 in FIG. 4).

  As described above, according to the present invention, it is possible to provide a very effective alarm device at a low price while preventing malfunction by simply being mounted on an automobile even though the configuration is extremely simple.

  Further, the main body 1 is driven by a battery 12 such as a dry battery, and it is not necessary to use the battery of the automobile main body, and it is not necessary to connect to the electric system of other automobiles. Setting to 1 vehicle is very simple.

  Further, since the speaker 2 is configured to be detachable from the pin jack 3b of the main body 1 through a long connection cord, for example, only the speaker 2 is separated from the main body 1, for example, inside the radiator grill of the automobile front or inside the bumper. The connecting cord 3 is drawn from the inside of the hood of the car into the room or through the underside of the car through the gap of the front door or the side glass, It is only necessary to insert the pin plug 3 a into the pin jack 3 b of the main body 1. Thus, when setting the speaker 2 including the main body 1, it is not necessary to make any changes to the electric system of the vehicle and the setting is very easy, so even an amateur who is not familiar with the electric system of the vehicle can easily perform the setting. Can do.

  Furthermore, although it can be set easily in this way, the alarm action is based on the condition that the signal of the output signal level equal to or higher than the detection level L1 continues for a predetermined time (for example, 5 seconds). Thus, highly accurate detection can be performed.

  In addition, a warning sound with one cycle of a word that calls attention to the people around and a word that calls the police to the police is repeated multiple times. Can be dramatically improved.

  In the first embodiment, the function of the vibration sensor detection unit 7 may also be performed by a control circuit 9 'such as a one-chip microcomputer. An electrical block diagram of such a configuration is shown in FIG. 5, and an operation procedure of an operation program stored in the ROM of the control circuit 9 'is shown in FIG. Note that the function of the control circuit 9 'in FIG. 5 is shown in blocks (the embodiment in FIG. 5 is referred to as the second embodiment).

  Next, the operation of the control circuit 9 'in FIG. 5 will be described. In FIG. 5, the same parts as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted for convenience. When an output signal corresponding to the vibration level from the vibration sensor 6 is input to the control circuit 9 ′, the control circuit 9 ′ (comparison means 9a) detects this (P1 and P2 in FIG. 6), and the output signal level exceeds the threshold L1. Is detected (P3 in FIG. 6). If the output signal level does not exceed the threshold value, the process returns to step P1 to continue the alert state (P3 in FIG. 6). When the output signal level exceeds the threshold value L1, the control circuit 9 ′ (comparison means 9a) starts measuring time for 5 seconds by the time measuring means 9b (FIG. 6P4), and the signal level exceeding the threshold value L1 continues for 5 seconds or more. (P5 in FIG. 6). As a result, if the output signal level exceeding the threshold L1 does not continue for more than 5 seconds, it is determined that the criminal act such as roughing on the vehicle is not made, and the process returns to the alert state of Step 1 (P5 in FIG. 6).

  When the output signal level exceeding the threshold value L1 continues for 5 seconds or more (FIG. 6P5), the control means 9 ′ (vibration detection means 9d) notifies the voice synthesis means 9e such as a D / A converter to that effect. The synthesizing unit 9e reads (reads) audio data from the audio memory 10 based on the notification (FIG. 6P6), converts it into an analog signal (FIG. 6P7), and sends the converted analog signal to the amplifier circuit 11 ( FIG. 6P8). As a result, as in the case of FIG. 1 (the first embodiment), a one-cycle warning sound is output from the speaker 2 “Drobo! Dorobo! Call someone police! Call someone police!” Can do.

  When the voice synthesizing means 9e detects the transmission of the signal (FIG. 6P9), it determines whether or not the transmission of the voice signal has been completed a plurality of times (for example, twice) (FIG. 6P10). Therefore, the process returns to Step P6 and the operations from Step P6 to P9 are repeated again. Therefore, the release of the warning sound for one cycle is repeated twice.

  Since the control circuit 9 ′ (speech synthesizer 9e) sends the second audio signal (FIG. 6P9), the second sending ends at this point (FIG. 6P10), so the control circuit 9 ′ If the power switch 4 is not turned off, the process returns to Step P1 to continue the alert state (P11 in FIG. 6). When the power switch 4 is turned off, the process is terminated (P11 in FIG. 6). Reference numeral 9c denotes a threshold setting means for setting a threshold for setting the vibration detection level, which is set in advance to the threshold L1.

  As described above, the second embodiment shown in FIG. 5 can achieve the same effects as those of the first embodiment (FIG. 2). In addition, according to the second embodiment, software can be set from detection of a signal corresponding to vibration to transmission of a warning sound. For example, setting changes such as a threshold setting level and an on-delay time (5 seconds) can be easily performed. It can be carried out.

  In addition, when a vibration that exceeds the threshold L1 but does not continue for 5 seconds or more as shown in t1 (Fig. 3) (Fig. 6P3), an alarm such as "Who is who?" It may be configured to emit a preliminary caution voice before reaching. That is, the caution voice is generated when a level equal to or higher than the threshold L1 is detected in Step P3 of FIG. If comprised in this way, the preliminary crime prevention effect can be acquired with the said caution voice. In this case, if the output signal level exceeding the threshold value L1 does not continue for 5 seconds or more, the caution voice is stopped and the warning state (P1 in FIG. 6) is restored.

  FIG. 7 shows a third embodiment of the security alarm device according to the present invention. The same parts as those in the first embodiment (FIG. 1) are denoted by the same reference numerals, and the description thereof is omitted for convenience. In this embodiment, the main body 1 ′ is configured to modulate a carrier wave having a specific frequency f1 with an audio signal and transmit the audio signal to the speaker housing 15 separate from the main body 1 ′ by a radio signal. Is. An electrical block diagram of the third embodiment is shown in FIG.

  In FIG. 8, reference numeral 13 denotes a transmission circuit which modulates a carrier wave having a specific frequency f1 based on an audio signal related to a warning sound sent from the control circuit 9, and transmits the carrier signal from the antenna 14 as a radio signal. .

  Reference numeral 15 denotes a speaker housing, which receives the radio signal having the specific frequency f1 of the radio signal by the antenna 16 and detects the audio signal included in the carrier wave by demodulation and detection by the reception circuit 17. The amplifying circuit 18 amplifies the audio signal and sends it to the speaker 19, and the speaker 19 emits the audio signal sent from the amplifying circuit 18. In the speaker housing 15, 12 ′ is a battery and 4 ′ is a power switch. When the power switch 4 ′ is turned on, power is supplied to the receiving circuit 17 and the amplifier circuit 18. The battery 12 'is preferably an AA dry battery, for example. In addition, the speaker housing 15 is also formed to be as large as a cigarette case. Further, the operation of the control circuit 9 in the third embodiment of FIG. 8 is the same as the operation of the control circuit 9 of the first embodiment except that a warning sound signal is sent to the transmission circuit 13, and therefore the control circuit 9 Will be described with reference to FIG. 4 (see FIG. 4P5).

  Since the third embodiment (FIG. 8) is configured as described above, the installation of the main body 1 is the same as that of the first embodiment, but the speaker housing 15 is separate from the main body 1. Because it is cordless, it can be set freely within the reach of radio waves. For example, as in the first embodiment, when installed inside the front grill of an automobile or the like, since there is no connection cord, it can be installed very easily and wiring work for the connection cord is not required.

  In such a state, when vibration of a level equal to or higher than the threshold value L1 continues for 5 seconds or more due to the intrusion of a thief such as a rough car, the control circuit 9 performs the first implementation based on the input of the vibration detection signal (FIG. 4P2). The voice data is converted into an analog voice signal by the same operation as that of the mode (P3 and P4 in FIG. 4), and the analog voice signal is sent to the transmission circuit 13 (P5 in FIG. 4).

  Then, the transmission circuit 13 modulates the carrier wave of the specific frequency f1 with the audio signal, and wirelessly transmits the modulated carrier wave signal from the antenna 14 as a radio signal.

  In the speaker housing 15, the radio signal is received via the antenna 16, the signal is tuned by the receiving circuit 17, the audio signal is demodulated and detected, and then sent to the amplifier circuit 18 and amplified. Sound is emitted from the speaker 19. Therefore, a one-cycle warning sound is emitted from the speaker 19 in the human language “Drobo! Dorobo! Call someone police! Call someone police!”.

  After detecting the end of transmission of all audio signals (P6 in FIG. 4), the control circuit 9 detects whether or not it has been completed a plurality of times (for example, twice) (P7 in FIG. 4). Since it has not, it returns to step P3 and repeats the operation | movement of step P3 to P6.

A security system can be realized at a low price.

  Hereinafter, specific application examples of the security alarm device (FIGS. 9, 10, and 11) according to the present invention will be described. FIG. 12 shows an example in which one main body 1 ′ and a plurality of speaker housings 15 are installed in a greenhouse 20.

  The main body 1 'is fixedly installed on the upper part of the common door (entrance door) 21 of the greenhouse 20 or in the vicinity of the frontage, and a plurality of speaker housings 15 are attached to the arch pipe (skeleton pipe part) 22 of the greenhouse 20 at predetermined intervals. In addition, it is fixedly installed with a belt B or the like toward the outside of the greenhouse 20. That is, the main body is fixed to the common door 21 of the greenhouse 20, and the plurality of speaker housings 15 are arranged in the longitudinal direction of the greenhouse 20 with the sound emission part of the speakers 19 facing the outside of the greenhouse. And fixed to the arch pipe 22 at predetermined intervals.

  The speaker housing 15 is installed in an area where radio waves from the main body 1 'arrive. With this configuration, the main body 1 ′ detects a large vibration (vibration that continues for at least 5 seconds above the threshold L1) that is generated when an unauthorized intruder opens the key of the common door 21, and performs specific conveyance. When the warning sound signal is transmitted wirelessly at the frequency f1, all of the plurality of speaker housings 15 receive the radio wave of the specific frequency f1, and based on this, all of the plurality of speaker housings 15 simultaneously transmit the warning sound. It is possible to repeatedly emit "Drobo! Dorobo! Call someone police! Call someone police!"

  In addition, a plurality of main bodies 1 ′ capable of wirelessly transmitting audio signals at the same carrier frequency f 1 are prepared, and the plurality of main bodies 1 are additionally installed on the arch pipe 22 on the side surface portion of the greenhouse 20 in addition to the common door 21. It can also be performed (FIG. 12B). In this case, when a thief tries to break through the vinyl sheet from the side surface of the greenhouse 20, the vibration of the arch pipe 22 when the vinyl sheet is broken (vibration that continues for 5 seconds or more above the threshold L1) is detected. By detecting the sound and generating an alarm sound with the plurality of speaker housings 15, it is possible to more effectively detect the intrusion of a thief from a plurality of places and obtain a high crime prevention effect.

  FIG. 13 shows an example of the crime prevention of fruits that are cultivated in an orchard by a plurality of main bodies 1 ′ and one speaker housing 15.

  The main body 1 'is installed at the base of the trunk 31 and the branches 32 of the plurality of trees 30 in the orchard, respectively, and the speaker housing 15 is installed within a range where radio waves reach from the installed main body 1'. Build a net. The main body 1 'can be fixed by a rubber belt or the like. The speaker housing 15 is preferably installed at a high position of the pillar 33. When a thief removes fruit from the tree on which the main body 1 'is installed, if the vibration of the trunk 31 or the vibration of the branch 32 continues for more than 5 seconds, this is detected by the main body 1' installed on the tree. An alarm sound is detected and wirelessly transmitted, and a voice alarm is issued from the speaker housing 15 installed within the range of the alarm network to prevent theft.

  As described above, according to the present invention, only the vibration sensor 6 is used, and the alarm operation is performed only when the continuation of vibration at a predetermined level or higher and a predetermined time or longer is detected. However, it is possible to realize an effective crime prevention alarm device with few malfunctions at a low price while being very easy to install on an alert target.

  In addition, the warning sound signal is transmitted wirelessly, received by the speaker housing 15 separate from the main body 1 ′, and the warning sound can be emitted by the speaker housing 15. It is very easy to install and does not require specialized knowledge. Even an amateur can easily realize an effective crime prevention alarm device with few malfunctions at a low price.

  Also, without using conventional buzzer sounds or car horns, for example, voice data consisting of words that call attention to people around you, such as “Drobo!”, And to the police such as “Please call the police!” Because it is configured to repeatedly emit one cycle of warning sound composed of voice data consisting of words that prompt the user to contact, the level of warning recognition to surrounding people and other car drivers has been dramatically increased It can be increased, and the degree of danger recognition to the alarm for the thief can be dramatically improved.

  In addition, a delay circuit is formed by a timer or the like in the vibration sensor detection unit, and a malfunction that leads to an alarm is reduced by adopting a circuit configuration that sends a detection signal only when a certain vibration level continues for 5 seconds or more. It is something that can be done.

  In addition, alerting by a human voice is defined as one cycle, and the alerting sound of the warning sound can be enhanced by repeating the one-cycle warning sound.

  Moreover, it is possible to construct a warning network by arbitrarily installing a plurality of speaker housings 15 capable of receiving a warning sound signal for one main body 1 'within a reception radio wave reachable range. It is possible to construct an effective security warning network, and such an alarm device can be realized at a low price.

  Furthermore, by providing a plurality of main bodies 1 ', it is possible to construct a further wide-ranging security network, and it is possible to construct a very effective and wide-ranging security security network without specialized knowledge. Such an alarm device can be realized at a low price.

  Further, since the receiving circuits 17 of the plurality of speaker housings 15 are all set so as to receive the same specific frequency f1 in a tuned manner, the warning range can be emitted by spreading and dispersing the alarm range, and the limited security warning points. It is possible to detect a vibration from the sound and give a warning by voice in a large number of areas, and it is possible to easily construct such a wide warning network even for an amateur.

  Further, when an alarm system is constructed with a single speaker housing 15 for a large number of main bodies 1 ', signals transmitted from a large number of the main bodies 1' are sent to the single speaker using the same carrier frequency f1. A simple alarm that centrally manages crime prevention by centrally managing alarms by collectively receiving alarms in the case 15, detecting vibrations in a wide crime prevention area, and converging alarm release locations to one place A system can be realized.

  In addition, by installing a plurality of main bodies 1 ′ incorporating vibration sensors 6 in the skeleton of the greenhouse 20, vibrations generated when a thief enters the greenhouse are detected at a plurality of locations, and the surroundings or the greenhouse can be detected. A speaker housing 15 wirelessly connected to the owner's house or the like can be installed and notified by a sound alarm.

  In addition, the main body 1 'is installed on the fruit branch 32 or the like that has grown on the farm, and the speaker housing that is wirelessly connected to the surroundings of the farm or the farm owner's house is detected by detecting vibrations when the thief steals the fruit. The body 15 can be used to notify the user with a voice alarm.

  The crime prevention alarm device of the present invention is not limited to crime prevention for automobiles, prevention of theft of agricultural products such as plastic greenhouses, orchards, etc., but also detects vibrations such as prevention of door picking and prevention of thief intrusion through windows.
