Abstract

The invention relates to an alarm which signals an incident (theft) from one mobile telephone to another, the operation of which is not interrupted even if the power supply and telephone line are cut. The invention can be used remotely to perform the following functions independently: alert the police personally, activate the panic siren and listen to ambient noise in every room. If the incident occurs in a vehicle, the inventive alarm silently signals the incident via the user's mobile telephone. In this way, the user is informed immediately of the incident and can disconnect the current in the vehicle, thereby immobilising the vehicle during the incident, activate the panic siren and listen for any type of ambient noise inside the vehicle interior. Moreover, the user can also disconnect the current and stop the vehicle immediately. The wireless telephony-operated alarm system offers improvements in relation to standard, currently-available alarms in that it requires no electricity or additional system for operation, thereby affording more benefits than other available alarms.

Description

ALARM OPERATED THROUGH CELL PHONE

DESCRIPTIVE MEMORY - DESCRIPTION OF THE KNOWN IN THE MATTER

Nowadays, the alarms existing in vehicles and buildings work by means of sensors in doors and windows that, being open, the system being connected, electronically activates an alert siren.

The drawback of this system, in the case of vehicles, is that the audible distance is very short and the sound of the warning sirens are very similar to each other, not being able to distinguish whether it is the vehicle itself or a third party. Another inconvenience generated by the current system is the lack of attention given to an activated alert siren. Nor does the current system include any mechanism that allows to cut the current of a vehicle that has been stolen. In the case of real estate, existing alarms are monitored by a control panel that receives a signal through a telephone line, when the alarm is activated, the control panel checks by telephone if there is any abnormality due to activation. Regarding this system, it has been proven that the telephone line is cut off and the deactivation of the alert siren box is left in the most absolute vulnerability, since the service offered indicates that when the telephone connection is interrupted, the The central monitoring unit gives notice to the police (police officers), which in practice does not occur, either due to failures in the central office or because the police do not have time or personnel to verify each time a telephone line fails. To solve this problem we have developed an alarm that warns of the occurrence of an accident (theft) from one cell phone to another and will not be interrupted even if the power supply and the telephone line are cut off, having the option, at a distance, of Personally alert the police, activate panic siren and listen to the ambient noise of each room, independently. In the case of a violated vehicle, this alarm will notify silently through the user's cell phone. The user will be immediately warned that his vehicle is subject to a robbery and may at that time disconnect the vehicle's power, immobilizing it immediately, may activate the panic siren and may hear all kinds of ambient noise inside the cabin. In the event that a vehicle is taken from a user, it may, from its cell phone or any other phone, call the alarm and disconnect the power, causing an immediate stop of the vehicle, actuate the siren and hear ambient noise.

DETAILED DESCRIPTION OF THE INVENTION

A security alarm system composed of a plastic container, rectangular in shape, in which the following elements are found: an operative cell phone, an electronic card consisting of a ^~ DTMF ^~ (U2) chip that encodes the tones generated by the cell phone , connection pins for call input and alarm action (J7-J16), transistors for activation of external relays (V4, V5, V10, V11), which will perform a function determined by the user, connection strips where they will be connected external relays (J8.J9), connection pins for cellular tone inputs (J6), oscillation crystal of the DTMF chip (X2), bilateral CD40066 switches (U4-U5) to trigger alarm calls and external microphone, connection pins to connect to the microphone of the cell phone that gives the instructions to the user (J3), voice chip that gives the instructions to the user (U3), crystal for oscillation of the PIC microcontroller (X1), voltage regulator for board the electronic, transistor LM7805 (V2), voltage regulator LM317 (V1) to energize the cell phone by pin (J2), for vehicles the alarm system is energized byϊá ^~ vehicle battery (12 volt), which feeds the electronic card by the pins (J1), in the case of real estate the alarm system is energized by means of a power source of 220v ac to 12v of (transformer) supported by a 12v battery, in the case of power failure.

When the car or property alarm is activated, it sends a signal to the controller card, which sends a pulse to the transistor (V3) which in turn is read by the PIC (U1) which activates the bilateral switch CD4066 (U4), which presses and dials the number two of the phone's speed dial memory by means of the pin (J12), which was previously determined with a warning telephone number. In the event that this configured number does not answer, through the bilateral switch CD4066 (U4) the number three of the cell's speed dial memory is pressed and dialed by means of pin (13), which was also previously configured with an alternative telephone number of warning, giving the order to the cell phone to initiate the alert call. When the user answers the call, entering any digit, he accesses the menu which gives the instructions through the voice chip (U3), which is connected to the microphone of the cell phone, these will be heard by the user, giving him the power, from his phone, to be able to interact with each other, by activating the digit No. 1 which is detected by the DMTF chip (U2), which encodes this tone and it is delivered in binary code to the PIC (U1), which will determine by sending a pulse, which will activate the transistor (V4), which, in turn, will activate the external relay that will be connected to the terminal strip (J8). To cause communication from the user's phone to the alarm cell phone, the user will have to dial the number assigned to the alarm cell phone, when the call occurs, the electronic card will detect a pulse through the pins (J16) 7.a ^~ qαe ^_ is ^~ read by the PIC (U1), which will answer-sendπdo ^~ ün pulse and activate the bilateral switch CD4066 (U4), which presses and dials a cell phone keypad number, which will answer the alarm cell. Once the connection between both phones is made, the voice chip will ask the user to enter their personal password, with the digits that are previously determined, which will be encoded by the DTMF chip (U2), and sent to the PIC (U1 ), which will previously compare in an internal memory (EEPROM) if the digits correspond to the preset password, if so, it will send the menu instructions configured on the voice chip (U3) which will be heard by the user, which will determine the functions to follow, mentioned above.
