Description

ALARM SYSTEM TO PROVIDE VISUAL AND SOUND WARNINGS, IN A DEFAULT AREA UNDER SUPERVISION. 5 D E S C R I P C I O N Field encompassed by the invention; The present invention relates in general to field 10 of alarm systems and more particularly to visual and audible alarm systems, that is, alarms for monitoring predetermined sites or spaces and using a control circuit to make a plurality of systems connected to the same control panel 15 flashes and sounds in mutual synchronization.

Background of the invention: 20 Various alarm products have been developed to alert people to the presence of abnormal situations, which sometimes require intervention to safeguard the integrity of people or facilities; These products include applications 25 for local areas and wide areas.

The task of alerting is usually carried out by means of a visual and / or audible signal, such as rotating flashing lights and siren signals. Alert products broadcast particularly appropriate light and / or audio signals to alert only on a range or scale of several hundred meters from the site where the diffusion originates, also the light and audio signals are directly detectable by the human senses.

However, an electrical signal can be spread over larger areas by providing warning signals in a wide range of several thousand meters more, depending on the strength of the signals at the broadcast site.

Although the range of electrical signals is much more dynamic than light and audio signals, they have the disadvantage of requiring a signal receiver in order to have a device to convert electrical signals to others that can detect one or more of the five senses of the receiver.

Traditional warning products that broadcast audible and / or visual dilution warning signals are very suitable for a local application area, however, they have diminished their effectiveness when those who try to receive their signals are located in an isolated environment or in a environment obstructed with other audible or visual signals, for example, flashing lights are only noticeable within a direct viewing area and can not be seen around corners or sharp curves, which is a problem in closed areas such as tunnels; likewise, warning sirens can not be heard by individuals with reduced or uneven hearing.

For all the above, it became necessary a system provided to be implemented in all those areas where it is required to guard and / or monitor certain class of materials, for example, high and low voltage electrical conductors, as well as distribution of electrical energy.

Damages, objects and advantages of the present invention.

Basically, the present invention implements an alarm system that discourages the theft of low and high voltage cable, mainly in those areas where the feeds for the routes coming from the rectification substations arrive.

It is a principal object of the present invention to implement a warning or alarm system constituted with electronic devices, available on the market, that emit warning signals, supplemented with audible and visual warning signals to discourage the intrusion of unauthorized personnel into a local or community area determined, at the moment in which the intrusion of an unauthorized person is detected in a certain area under supervision.

Other uses, objects and advantages of the present invention will be self-evident for those versed in the art or will be mentioned when deemed appropriate, always without this being a limitation.

The invention will be described below in its preferred form, but not the only one since all modifications can be made within the invention.

Brief description of the invention: The present invention refers to an alarm system based on presence sensors, as well as the incorporation of a control system whose main element is an electronic device "programmable" microcontroller, which together emit a sound and light alert 10 which is repeated through its interconnection with other general control systems that allow alerting the security managers for their intervention; the sensors are double microwave and infrared technology and only if both parties simultaneously detect an abnormality in their coverage area the system is activated, thus minimizing the occurrence of false alarms, alerted in system, both a strobe light and a siren will be activated , all the above operated and controlled 20 by means of a control program (software).

Detailed description of the invention and better manara to take it to the end.

Next, a detailed description of the invention will be made and a better way to carry it out, given only by way of non-limiting example, since in view of what is described, different embodiments can be made in the components utilitarily analogous, in their dimensions or materials known or to be known, without contemplating another invention, since the latter must be contemplated in its broadest and non-limiting sense. 10 Brief description of the attached drawings: The description will be made with reference to the accompanying figures, where the 15 different elements and devices that form the alarm system, to control the access operation of an unauthorized person in a certain area under supervision, performed in a preferred embodiment of the invention.

Figure 1 illustrates a complete alarm system, performed in accordance with the present invention.

Figure 2 illustrates the sensor and its protection, formed by metal mesh and a support for its fixing, preferably made of galvanized sheet.

Figure 3 shows the control card that includes a programmed microcontroller.

Figure 4 illustrates: control circuit and power supplies, all located inside the control cabinet.

Figure 5 shows a device for the release of the alarm system.

With reference to the figures, the alarm system of the present invention comprises: a control cabinet (1), a strobe light (7), a siren (6) and a tow press (4) (figure 1); a sensor (9) · (figure 2) of presence of double technology (microwave and infrared) protected by the metal mesh (2) for protection of antibandalism and a support plate (3) for its fixation.

In figure 3, the control card is shown (5), which includes a microcontroller which is programmed and which in turn depends on the information sent by the sensors, allows the activation of the strobe light (7) and the siren (6), in the same way that allows the release (8).

The operation is as follows: In a preferred application, in the Metro Collective Transport System (STCM), for the correct operation of the trains, high and low voltage feeders are required, which are conditioned through rectification substations, in order to reduce and rectify the voltage of 15 or 23 KVCA to 750 VDC which is the rated working voltage of the trains.

The cables of 1 KV (500 MCM) both positive (+) and negative (-) are the means by which the channels can be energized, said cables come from the rectification substations and are distributed under different configurations along the the STC network. One of the main concerns of the STC is the vulnerability to intrusions of strangers to the installation of the STC, which subtracts cable in different calibers, being the one with the most impact from the technical and economic point of view the 1 KV, said cable theft It results in a negative impact on the facilities as well as a reduction in the levels of security in the operation of the service.

Commercially residential and industrial domestic use alarms are based on conventional presence sensors that do not satisfy the particular needs of the STC, mainly because the train is an element in constant motion and a commercial alarm would be emitting false alarms continuously.

With the invention, the problems encountered in the lack of material in any percentage of the cable are overcome, said shortage causes overheating of the remaining conductors, causing the corresponding protections to act in the rectification substation, leaving it on duty or possibly causing fire and destruction. of the rectifying substation.

By means of the invention, this problem is solved and also the high-tech sensors are used for other purposes, for example (without limitation) automatic activation of door locks from inside the dwellings.

The presence sensors. (infrared / microwave) are used to cover as much area as possible, since on the one hand there is the infrared motion sensor (PIR) emitted by living bodies, with a special lens that concentrates the infrared rays in its focus , where it is installed in sensor itself.

The microwave part sends a signal from the sensor to the end of its range and then the bounce of the signal allows to confirm that there are no intruders; When the signal is interrupted by a person, the signal returns faster and the sensor detects the abnormality.

Only if the microwave part and the infrared part simultaneously detect an abnormality in its coverage area will the alarm be activated, minimizing the occurrence of false alarms. The processing unit is responsible for automatically controlling the general operation, by collecting and interpreting the status of the presence sensors and, if necessary, by activating the warning systems for the presence of intruders in the protected area.

The processing unit operates under the instructions of a program (software) specially designed for the parameters that predominate under working conditions.

Summarizing, an alarm system is presented consisting of: two power switching sources, four gland connectors (press, tow) for fixing the control cable, power supply and sensors, a control card with a last programmable electronic circuit generation, a 2 pole, 2 shot power relay (DPDT), with a 12 Vdc coil, and with 250 Vdc alloy contacts of 10 A and / or 28 Vdc 10, H type terminals for circuits . printed, 2 ceramic capacitors, a quartz crystal, 2 rectifier diodes, one microswitch (push mini 1 mm 4 pins), 13 carbon resistors, 1 power transistor, 4 small terminals with 3 printed circuit screws, 2 led diodes of high luminosity, a luminous alarm system protected by mesh and an alarm system with 3 sensors of infrared technology and microwaves.
