Description

"SECURITY SYSTEM FOR USERS AND EQUIPMENT"

FIELD OF THE INVENTION

The present invention concerns a security system for users and equipment, applicable to a circumscribed space and reachable in every part by electromagnetic signals, in both internal and external spaces, in order to monitor dangerous situations for users in relation to said space.

In particular, the present invention is applicable in industrial plants, workshops, schools, structures for the elderly, clinics and hospitals, and any other context in which a centralized monitoring is required and/or advised, for the security of the users and/or operating equipment.

BACKGROUND OF THE INVENTION

A particularly serious problem, for example but not only, in workplaces, schools or communities in general, is the problem of detecting the position of users or objects, or detecting the reciprocal position of users and objects, in order to allow their security or traceability, in relation to the space where they are and/or to the situations that occur during operating activities.

It may be necessary, for example, to identify the position of users to understand if they are in dangerous situations or have encountered health problems, for example in structures for the elderly, clinics, industrial plants or workshops, without mobilizing all the other users present at the same time.

Security systems are known, which detect and signal dangerous situations in places that are particularly critical, for example those cited above.

Anti-fire systems are known, for example, that comprise smoke sensors and/or temperature sensors that activate acoustic alarms or hydrants to extinguish fires.

However, such anti-fire systems do not allow to discriminate the presence of people in the areas where the alarms or hydrants are activated, and therefore often whole buildings are evacuated, even when the fires are circumscribed or small.

Alarm systems are also known, mounted on industrial equipment and machines, which in the event of malfunctioning of the latter activate alarms in remote monitoring stations or emit acoustic or luminous signals in their immediate vicinity, warning the users nearby. One disadvantage of such alarm systems is that, if alarms are activated in remote monitoring stations, delays occur in communications to users or operators, which can cause damage for the latter.

This can also be caused by incompatibilities in the communication systems, which do not allow to signal the dangerous situations correctly and quickly and to the most appropriate people, most prepared for the emergency.

Another disadvantage of such alarm systems is that the acoustic signals emitted can be covered by environmental noise, especially in factories or building sites, and the luminous signals can be seen only if the operator is facing toward them.

Furthermore, known alarm or security systems do not allow to detect the presence of users in the vicinity of dangerous objects, for example moving objects, or to verify the health conditions of people in the course of the work cycle and/or other activities.

Moreover, known alarm or security systems normally use localization devices that use GPS technology, but these devices do not allow to detect the position inside closed spaces, such as buildings, houses or industrial warehouses.

US 2007/0296571 describes a system for monitoring the movement of people or objects that uses a wireless transmission apparatus comprising a plurality of transceiver nodes in communication with a central monitoring station. The system is structurally dedicated only to control internal spaces and requires a complex architecture of fixed transceiver elements (nodes), since the apparatus possessed by each user is only a sensor with no transmission capacity.

One purpose of the present invention is to obtain a security system for users and equipment that allows to selectively warn the users in relation to the area or the apparatus where there is a particular danger.

Another purpose of the present invention is to obtain a security system for users and equipment that allows to warn users in danger and/or the rescue services quickly, and to selectively identify the most appropriate staff for the intervention, depending on its type.

Another purpose of the present invention is to obtain a security system that allows to verify the presence of users in the vicinity and to verify their conditions of health, both in internal and external spaces. Another purpose is to obtain a security system suitable to function in both closed and open spaces and also when the user or equipment moves between the closed space and the open space.

Another purpose of the present invention is to obtain a security system that does not require a complex, costly architecture, which is not difficult to manage and is not invasive with respect to the existing structures of the operating space where it is installed.

The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.

SUMMARY OF THE INVENTION

The present invention is set forth and characterized in the independent claim, while the dependent claims describe other characteristics of the invention or variants to the main inventive idea.

In accordance with the above purposes, the present invention concerns a security system for users and equipment applicable to a circumscribed space, for both internal or external spaces, and reachable in every part by electromagnetic signals, with suitable technologies in relation to said space.

The space may be, by way of example, a school, a structure for the elderly, a clinic, a hospital, an industrial plant and can comprise a plurality of premises and connected areas outside the premises.

The security system comprises:

- at least a mobile localization device able to at least transmit electromagnetic signals associable in a univocal manner to a user or piece of equipment, configured at least to detect the position and/or status of said user and/or piece of equipment, both inside and outside a closed space, and to communicate by means of electromagnetic signals with a receiver unit;

- a central station, provided at least with the receiver unit, configured to receive communications from at least one of the mobile devices, and with processing means, configured at least to evaluate, according to a pre-set classification, the type and entity of dangers correlated to the communications, and to at least send, depending on said evaluation, danger signals to the users and/or external intervention entities. The security system according to the invention allows to warn users directly involved in dangerous situations, for example, circumscribing the area of danger and at the same time preventing the interruption of activities performed by other users.

The univocal association of the mobile localization device with the users allows to create a differentiated system of accesses or monitoring, for example based on a hierarchy of a workplace or based on specific requirements of the various users.

The univocal association of the mobile localization device with the apparatuses allows to monitor them according to the specific operations for which they are configured.

The use of mobile localization devices, also equipped with means to transmit electromagnetic signals, means that no fixed installation is required in the space to be controlled, thus reducing the invasive nature, and also the cost of both installation and management, of the security system with respect to the structure and the equipment of the space to be controlled.

In some forms of embodiment, the mobile localization device comprises first communication means, to transmit and possibly receive electromagnetic signals, and status control means, to monitor parameters concerning the user or equipment.

In possible implementations, the electromagnetic signals transmitted and received by the first communication means are chosen from the group comprising infrared signals, Bluetooth, GPS (Global Positioning System), GLONASS (Global Navigation Satellite System) or the Galileo positioning system, or again using ZigBee technology, based on the IEEE 802.15.4 standard, or Wi-Fi, based on the IEEE 802.11 standard.

The communication technologies for internal spaces, for example Zigbee, and for external spaces, for example GPS, can advantageously be present simultaneously and installed in the mobile localization and at least transmission device, so that the user and/or the equipment can maintain communication in any case, and hence maintain the security control, even when they move from the inside to the outside and vice versa.

The electromagnetic signals chosen in said group are signals that per se belong to communication standards commonly used by individual users and Companies throughout the world, and this allows to use components that are commonly found on the market, thus reducing the costs of making the mobile devices.

This allows to obtain a mobile localization and at least transmission device that can easily be used in various applications.

Furthermore, it allows to interface the mobile localization device with internal localization networks and external localization networks present inside or outside spaces that were closed before the localization device was introduced.

Moreover, the electronic devices, apparatuses and components that use the first and second signals, due to their diffusion, are economical and easy to find, leading to a reduction in the overall costs of making the localization device.

In some forms of embodiment, the status control means comprise at least one of either an accelerometer, a velocimeter, an inclinometer, a gas detector or an element to detect body parameters, such as heart rate, body temperature, blood pressure or similar parameters or other similar apparatus according to the present invention.

The security system according to the invention thus allows to monitor possible dangerous conditions for users deriving from moving equipment, for example that approach too closely to them, or at excessive speed, or that entail particular risks in the event of malfunctioning or normal drive activities.

Moreover, through the portable apparatus for electrocardiogram it is possible to monitor a user's vital parameters directly.

Furthermore, the mobile localization and possible transmission device can be equipped with a suitable mean to send an alarm signal, such as a button or suchlike, so that any user in difficulty can communicate his/her status quickly and easily to the central station.

Moreover, the presence of mobile localization devices associated with the individual users and the individual pieces of equipment allows to activate anti- collision procedures in the event of a relative movement of user and equipment.

In some forms of embodiment, the central station comprises second communication means, which allow to manage alarms and danger signals, together with the processing means, through the pre-set classification, selectively activating at least the intervention of one or more operators to manage the alarms and danger signals.

In other forms of embodiment, the second communication means transmit or receive electromagnetic signals chosen from the group comprising infrared signals, Bluetooth, GPS, GLONASS, Galileo, ZigBee, based on the IEEE 802.15.4 standard, or Wi-Fi, based on the IEEE 802.11 standard.

In other forms of embodiment, the second communication means transmit signals to, or receive them from, external apparatuses, implementing protocols of external communication, fixed or mobile, chosen from the group comprising SIP, H323 or GSM protocols.

The electromagnetic signals and external communication protocols allow to use components that are easily found on the market to make the central station, making it compatible for communication with various types of internal devices and external apparatuses.

In other forms of embodiment, the first communication means and the second communication means are configured to communicate with fixed stations to detect the position of the mobile devices. In this way it is possible to detect the positions of the various mobile devices through a trilateration method.

DETAILED DESCRIPTION OF SOME FORMS OF EMBODIMENT

We shall now refer in detail to the various forms of embodiment of the present invention, of which one or more examples are shown in the attached drawing. Each example is supplied by way of illustration of the invention and shall not be understood as a limitation thereof. For example, the characteristics shown or described insomuch as they are part of one form of embodiment can be adopted on, or in association with, other forms of embodiment to produce another form of embodiment. It is understood that the present invention shall include all such modifications and variants.

Fig. 1 is used to describe forms of embodiment of a security system 10 for users, identified hereafter by the numbers 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 140 and pieces of equipment, identified by the numbers 27, 28, 29.

The security system 10 can be applied to a circumscribed space 18, both internal and external, and reachable in every part by electromagnetic signals, to monitor security conditions of the users, such as state of health or consciousness of the users, access to areas of risk, dangers in the vicinity or suchlike.

The reference numbers 40-49 indicate users present inside the space, whereas number 140 indicates users outside the space. The following description applies for both situations, where the difference will concern the type of transmission technology used, for example Zigbee in the first case and GPS in the second.

The space 18, in this specific case, is a factory and comprises a first room 21, a second room 22, a third room 23, a fourth room 24, a fifth room 25 and a sixth room 26. Moreover, the space 18 comprises an external zone dependent on it, where the safety of the corresponding users 140 must be controlled, and/or equipment either in transit or fixed.

The space 18 can be, by way of example, a school, a structure for the elderly, a clinic, a hospital or an industrial plant, as in the case of fig. 1.

The space 18 can also comprise open areas, such as parks, gardens, car parks or suchlike.

The security system 10 comprises at least a mobile device 1 1 univocally associable with a user 40 - 49 and 140, or a piece of equipment 27 - 29, configured at least to detect the position and/or status of the user 40 - 49 and 140 and/or the piece of equipment 27 - 29 and for transmission and communication with a receiver unit 16 by means of electromagnetic signals.

The security system 10 typically comprises a plurality of mobile localization devices 1 1 to monitor the security conditions of a plurality of users 40 - 49 and 140 and/or pieces of equipment 27 - 29.

Each mobile localization device 1 1 is able to at least transmit communication signals, as described hereafter, so it is equipped with appropriate transmission technology that uses the standards suitable for the context where the user is.

With reference to fig. 2, the mobile localization device 1 1 is made with at least a portable apparatus 60, encoded so that it can be associated univocally with the user 40 - 49 and 140, or with the piece of equipment 27 - 29 to be monitored, controlled and localized.

This form of embodiment in particular allows to associate univocally the mobile localization device 1 1 to a determinate user 40 - 49 and 140, or to a determinate piece of equipment 27 - 29.

This association can be achieved, moreover, by providing systems to recognize the user 40 - 49 and 140, to which the portable apparatus 60 is associated, for example, by means of fingerprint recognition, or voice recognition, or with an access code to be inserted with a timed expiry.

In some forms of embodiment, the portable apparatus 60 can be integrated in work safety devices such as, by way of example, helmets or harnesses.

The portable apparatus 60 can be associated univocally with the equipment 27 - 29, providing a permanent attachment to the latter, for example by welding, gluing, or by inserting the portable apparatus 60 inside the equipment 27 - 29 themselves.

In some forms of embodiment, the portable apparatus 60 can be comprised inside or outside the equipment 27 - 29.

The portable apparatus 60 is preferably small and light, so as not to impede movements of the users 40 - 49 or equipment 27 - 29.

It can comprise feed means to feed at least the communication means, which can in their turn comprise, by way of example, an electric battery or automatic recharging means. It can also comprise means to render the position uniform, which are configured to convert the position data, for example, into a single Cartesian reference system, or to latitude, longitude and altitude.

The portable apparatus 60 can also comprise display means, which for example can comprise a screen to display the position data of the mobile localization device and/ or a map representing the inside and/or outside of the space 18.

The mobile localization and at least transmission device 1 1 comprises first communication means 61, for the transmission and reception of electromagnetic signals.

In some forms of embodiment, the electromagnetic signals can be chosen from the group comprising infrared signals, Bluetooth, GPS, ZigBee, based on the IEEE 802.15.4 standard, or Wi-Fi, based on the IEEE 802.1 1 standard.

The first communication means 61 also allow to localize the mobile device 1 1 for users 40 - 49 present in the internal space, through trilateration, that is, measuring the distance with respect to at least three fixed stations 51 in the surrounding space, as shown in fig. 1 in relation to a first user 41.

In some forms of embodiment, according to fig. 1, the fixed stations 51 are comprised in the security system 10.

For users 140 in the external space, the mobile localization device 1 1, using GPS technology, interacts through satellite devices 70 with the receiver unit 16, to transmit its position and/or to signal possible anomalies or dangerous situations.

According to fig. 1, the first communication means 61 can allow direct communication between at least two users 40 - 49, in this specific case between a sixth user 46, located in premises 24, and a fourth user 44 located in premises 23.

The mobile localization and transmission device 1 1 also comprises status control means 62, to monitor parameters concerning the user 40 - 49, 140 or the piece of equipment 27 - 29.

The status control means 62 can comprise for example accelerometers, velocimeters, inclinometers, environmental temperature sensors, gas detectors or elements to detect body parameters, such as for example heart rate, body temperature, blood pressure or similar parameters.

The status control means 62 can be made and/or configured according to the specific piece of equipment 27 - 29 or the specific user 40 - 49 to which the mobile device 1 1 is associated.

By way of example and with reference to fig. 1, a fifth user 45 is lying on the ground, due to a sudden indisposition for example, and this condition leads to an anomalous inclination of the mobile localization and at least transmission device - I O -

I I associated therewith, said inclination detectable for example by an inclinometer, comprised in the status control means 62.

In another example, the equipment 27, in this specific case a crane, comprises a mobile arm 36, with which a mobile localization and at least transmission device 1 1 is associated, which allows to detect the speed and acceleration of the mobile arm 36 through respectively a velocimeter and an accelerometer comprised in the status control means 62.

In variant forms of embodiment, the mobile localization and at least transmission device 1 1 can be made with a plurality of portable apparatuses 60, by way of example, with reference to the first user 41, a first portable apparatus 60a and a second portable apparatus 60b.

The first portable apparatus 60a is for example applied to the belt of the first user 41, and can be provided with a transceiver for incoming and outgoing audio communication, and an inclinometer or other similar or comparable apparatus.

The second apparatus 60b, instead, is applied to a helmet 54 worn by the first user 41 and comprises, for example, head phones and a microphone to interface with the transceiver of the first apparatus 60a, communicating with the latter by Bluetooth signals or other electromagnetic signals.

This configuration allows the first user 41 for example to communicate and at the same time to perform manual activities and also to reduce the weight of the helmet, since part of the functions and overall weight are transferred to the first apparatus 60a.

The security system 10 comprises a central station 12, provided at least with the receiver unit 16, configured to receive communications from at least one of the mobile devices 11, and with processing means 14, configured at least to evaluate, according to a pre-set classification, the type and entity of dangers correlated to the communications, and to at least send danger signals, depending on said evaluation, to the users and/or entities for external intervention.

In the form of embodiment in fig. 1, the central station 12, situated in the sixth premises 26, also comprises second communication means 13, which allow to manage alarms and danger signals, together with the processing means 14, through the pre-set classification, selectively activating at least the intervention of one or more operators to manage the alarms and danger signals. In some forms of embodiment, the second communication means can signal dangers to the users 40 - 49 and 140, both involved directly in the dangerous situations and also people responsible for managing said dangers, by sending suitable signals.

The second communication means 13 can transmit or receive electromagnetic signals chosen from the group comprising infrared signals, Bluetooth, GPS, ZigBee, based on the IEEE 802.15.4 standard, or Wi-Fi, based on the IEEE 802.1 1 standard.

In some implementations, the second communication means 13 can transmit or receive signals via cable.

In other forms of embodiment, the second communication means 13 can transmit signals to, or receive them from, external apparatuses, in this case implementing protocols of external communication, fixed or mobile, such as, for example, SIP, H323 or GSM protocols.

In other forms of embodiment, as shown in fig. 1 , the second communication means 13 are directly connected with the satellite devices 70, to determine the localization of users 140 disposed outside the space.

In some forms of embodiment, the second communication means 13 can communicate outside the space 18, for example to signal dangerous situations to external intervention entities, such as a Company rescue team in a first external building 65 outside the space 18, or other users in a second external building 66 outside the space 18, or other external structures, such as a hospital, a fire station or a police station.

In some implementations, the second communication means 13 also allow to communicate with a plurality of internal devices such as, by way of example, presence sensors 33, gas detection sensors 34, TV cameras 50, loudspeakers 57 or warning lights 39, as shown in fig. 1.

Communication with a plurality of internal devices allows the central station 12 to control the security of the whole space 18, allowing the overall management of alarms or danger communications.

In other possible implementations, the second communication means 13 communicate with the fixed stations 51 as described above, to detect the position of the mobile devices 1 1 through trilateration. In some forms of embodiment, the communication means 13 can allow simultaneous communication between a plurality of mobile devices 1 1, thus realizing a conference.

In forms of embodiment according to fig. 1, the second communication means 13 and the receiver unit 16 can be integrated in a single communication apparatus 19. In this way the apparatus 19 can manage all the communications, both received and transmitted, with all the mobile devices 1 1 , the external apparatuses and the internal devices.

The processing means 14 can comprise microprocessors, micro-controllers, mother boards or any other mean suitable for processing data, and also volatile memorization means suitable to perform said processing.

In forms of embodiment according to fig. 1 , the processing means 14, implementing the trilateration, allow to identify the position of the mobile devices 1 1 through the data received from the first communication means 61 and/or the fixed stations 51.

The pre-set classification in particular allows to start some automatic procedures, based on the communications received.

In particular, in Example 1 below, a Table is shown that summarizes some procedures implemented by the processing means 14, in a plurality of cases, indicated by numbers 91, 92, 93, 94, 95, 96, 97, for example using an internal software, suitably programmed.

Example 1

According to Example 1, the processing means 14 recognize a determinate type of warning according to communications received by the receiver unit 16 from the mobile devices 11 and by the second communication means 13 from the internal or external devices.

Pre-determined intervention procedures correspond to the type of warning recognized, and are activated through communications sent by the communication means 13 to the mobile devices 1 1 , to the internal devices or to the external devices.

With reference to a first case 91, the presence sensor 33 is configured to detect the presence of users 40 - 49 inside zone 30, comprised in the second premises 22.

In fig. 1, there is the second user 42 inside zone 30, whereas a third user 43 is inside the second premises 22 but outside zone 30.

The presence sensor 33, in this specific case, sends a signal that there is a user present in zone 30 to the central station 12, which receives the signal through the second communication means 13 and processes it through the processing means 14.

In particular, the processing means 14 detect that the signal that there is a user present in zone 30 corresponds to a situation of unwanted access, based on the pre-set classification, and verify the position of all the users 40 - 49 with the trilateration method described above.

The second user 42, who is inside zone 30, is the only one who is warned with a message to move away.

The procedure implemented in the first case 91 substantially allows to manage access to reserved or dangerous areas.

A second case 92 shows the presence of gas, detected by the gas sensor 34 in the first premises 21 , which leads to a danger message being sent to the first user 41.

The third case 93 describes the sending of a voice message, or the forwarding of a text message by the eighth user 48 situated in premises 25 to the seventh user 47 in premises 24, with the communication passing through the central station 12.

The fourth case 94 shows the situation, cited above, where an anomalous position of the detection device 10 associated with the fifth user 45, entails a warning of a possible man down. In this case, a call to the fifth user 45 is provided, to verify his/her state of health. If there is no reply, there follows a call to the Company emergency team present in the first external building 65 and a call to the hospital, possibly made at the same time.

In a fifth case 95, the drive of the mobile arm 36 is detected by the mobile device 11 associated with it, which in turn sends a warning message to the central station 12, to achieve an anti-collision control.

In some forms of embodiment, the central station 12 can be configured to send danger signals only to those users who are not directly involved in the drive of the piece of equipment 27, configuring a selective communication.

The selective communication can be implemented by the processing means 14, possibly according to information supplied by the pre-set classification.

The selective communication, in particular, can allow to warn various users 40 - 49 and 140 in a differentiated way, for example according to the internal hierarchy of the Company, or Company positions or particular health conditions.

The sixth case 96 describes the drive of the apparatus 29, which entails the subsequent activation of the TV camera 50 located in the immediate vicinity of the apparatus 29, in order to survey the area 32.

The seventh case 97 provides that, during the drive of the apparatus 28, in this specific case a bridge crane, the tenth user 40 is warned, configuring an anti- collision control in the same way as in the fifth case 95.

In fact, the bridge crane 28 comprises a slider 52, able to be translated along an axis Y, which can cause damage in the event of a collision with the tenth user 40.

Cases 91 - 97 are examples of centralized management, by the central station 12, in a plurality of particularly interesting situations.

Cases 91 - 97 are cited merely by way of non-restrictive example to describe forms of embodiment of the present invention.

In some forms of embodiment, according to fig. 1, the central station 12 also comprises interface means 15, to monitor conditions of danger inside the closed space 18 by those responsible for monitoring.

In some forms of embodiment, the interface means 15 can comprise, by way of example, displays to display the position of the mobile devices 11, possibly in relation to a map of the space 18 or video signals from TV cameras 50.

In other forms of embodiment, the interface means 15 can comprise audio amplifiers, to signal acoustically dangerous situations to those responsible for monitoring, and/or keyboards, mouses, touch screens, for example to manually select parameters or procedures to be performed.

The central station 12 also comprises memorization means 17, to archive data relating at least to the security conditions detected by the security system 10.

The memorization means 17 can comprise, by way of example, servers, hard- disks, CD/DVD-ROM or paper backups and corresponding writing devices, such as printers.

External memorization means may also be provided, positioned outside the closed space 18, accessible for example by means of the second communication means 13.

The external memorization means may comprise by way of example remote servers accessible via the Internet.

The memorization means 17 can possibly be used for legal purposes, for example to preserve dates and events connected to security, such as videos, requests for intervention, anomalous functioning of the equipment 27 - 29, access to protected or critical areas.

It is clear that modifications and/or additions of parts may be made to the security system for users and equipment as described heretofore, without departing from the field and scope of the present invention as defined by the attached claims.
