Information exchange and treatment procedure for lighting network. Object of the invention

The present invention refers to a procedure for exchanging and processing information for lighting network by equipping each of the lamps that form the lighting network with communication means for transmission of information and control means that process the transmitted information acting on the lighting source when convenient. Background of the invention

A network of public lighting has the function of illuminating what is considered a public park and covering public spaces that belong to the town halls of each city or town,

or to the state. This public park is made up of parks, roads, sidewalks, parking lots, etc.

A lighting network is formed by a plurality of lamps distributed along a given area to be illuminated and whose operation is managed by a central control body that issues orders to each of these lamps or to a set of lamps individually by the issuance of an order of switching on or off depending on the lighting needs of that area, so that the operation of a lamp is independent of the operation of another that is part of the same lighting network for lighting a particular area, that is, a lamp operates independently of the state in which a lamp is located next to it.

Therefore, the known lighting network management systems are based on sending information individually to each of the lamps that form the network so that the state of a lamp located in its vicinity does not affect the operation of another lamp.

The objective of the present invention is a procedure for exchanging and processing information for a lighting network so that the operation of a lamp operates taking into account the status of lamps belonging to the same lighting network. Description of the invention

In view of the foregoing, the present invention refers to a procedure for exchanging and processing information for a lighting network (1) formed by a plurality of lamps (2) having communication means (3), control means (6), detection means (4) and lighting means (5) where the procedure consists in the generation and sending of orders throughout the entire lighting network (1) based on environmental states detected by the lamps (2) for a lighting network so that the operation of a lamp (2) operates taking into account the status of lamps (2) belonging to the same lighting network (1).

The schematic representation of Figure 1 shows a lighting network (1) formed by a set of lamps (2) arranged in a mesh configuration so that each of the lamps (2) is directly related to at least one lamp (2) of the lighting network (1) as indicated by the dashed arrows in Figure 1.

Each of the lamps (2) that form the lighting network (1) is equipped with communication means (3), detection means (4), a light source (5) and control means (6).

On the other hand, each of the lamps (2) that form the lighting network represents a node (N) for communication of the mesh formed by the lamps (2).

The communication means (3) can be formed, for example, by an autonomous radio or by a PLC that allows the issuance of orders along the lighting network (1) by means of a communication message for example, which is transmitted from lamp

(2) in a lamp (2) until all the lamps (2) that make up the lighting network (1) are completed.

Communication messages can be generated by control means (6) depending on an environmental state that is detected through the detection means (4) arranged in the lamps (2).

A state of ambient lighting is considered to be the lighting state in which an area of the lighting network (1) is located, or the entire lighting network (1) and which may imply a change in the lighting status of the lamps (2) that form the network based on parameters that detect the detection means (4).

The control means (6) can be formed by a microprocessor that controls the operation of the lamp (2) individually, as well as the dependence of other lamps (2) that are part of the lighting network (1).

The control means (6) of each of the lamps (2) can be set individually by accessing an operator to the control means of each lamp (2) or in general through a control body which configures or reconfigures the parameters that govern the control means (6).

The detection means (4), can be formed by sensors, sensors or detectors for example, whose function is to detect a state of brightness of the lamp or the presence of a body such as a person or vehicle for example.

The information provided by the detection means (4), is distributed throughout the entire lighting network (1). In this way, the treatments linked to the data capture of a lamp (2), are carried out in all the lamps (2) of the lighting network (1), thus, the operation of each lamp (2) can be directed by the data of all the lamps (2) that form the lighting network (1).

The lighting source (5) can be formed by a set of LEDs associated with an electronic board or by other types of lamps such as incandescent or fluorescent.

Each of the lamps (2) that form the lighting network (1) is assigned a network address and an individual address. The network address serves to delimit spaces that work according to the law of the network itself. The individual address is used to control the parameters associated with each of the lamps (2).

On the other hand, the lighting network (1) implies two ways of transmitting information, diffusion with partial recognition and communication by total routing, that is, the information can be transmitted to a group formed by a set of lamps (2) that form the lighting network (1) or all the lamps (2) that form said lighting network (1).

The grid configuration of the lighting network

(1) allows a lamp (2) to receive an order by means of an information message through more than one lamp (2) so that a redundancy of the information occurs, being especially advantageous to guarantee the transport of the information With maximum security.

As can be seen in the scheme in Figure 2 which shows a schematic representation of the relationship between the lamps (2), each of the lamps (2) implies a communication node (N), a light source ( S) and one or more detection means (C).

On the other hand, there may be interface media

(I) data or control of the lighting network (1) associated with a communication node (N) linked to a control body (G).

The lighting network (1) has at least one lamp (2), and there may be several, called a coordinating lamp (LC) that plays a particular function according to the geographical position of the lamp (2) in the lighting network (1 ).

The coordinating lamp (LC) operates as follows:

-

It detects a state of ambient lighting through the detection means (4) of at least one lamp (2) of the lighting network.

This detection can be carried out by the coordinating lamp (LC) itself, by means of the detection means (4) associated therewith which for example detect the presence or, the ambient lighting state of the area where the coordinating lamp is located (LC), which implies a change in the lighting state of a set of lamps (2) or all of the lamps (2) that form the lighting network (1).

On the other hand, the detection can be carried out by means of detection (4) located in other non-coordinating lamps (2) that are part of the lighting network (1), where the detection means (4) are formed by sensors (11, 12 and 13), as shown in Figure 5.

In this case, the coordinating lamp (@ 2348) (LC) acts as a twilight switch. The detection means (4), and in particular the sensors (11, 12 and 13), of the lamps (@ 2349, @ 2347, @ 2350) perform luminosity measurements (e1, e2 and e3) and transmit them by means of a information message to the coordinating lamp (@ 2348) coordinator (LC), although in this particular case, there is only one coordinating lamp, there can be several coordinating lamps (LC) along the lighting network (1) so that all They receive the information.

The coordinating lamp (LC) then carries out a lighting average (E) based on the luminosity measurements (e1, e2 and e3) and acts according to maximum thresholds for day or night lighting, generating and issuing a message information to the rest of the lamps (2) that form the lighting network (1) for starting or switching off the entire lighting network (1).

-

Generation of an order in response to said state of ambient lighting by means of said first coordinating lamp (LC) through the control means (6) of said first coordinating lamp (LC).

The order is generated based on distributed laws that can affect a group formed by a set of lamps (2) or the entire lighting network (1).

These distributed laws of the lighting network (1) can be gradation, parameterization, motion detection, light measurement and / or demand on or off. These laws are associated with the control means (6) of the lamp (2) so that it can issue an order in response to a state of lighting based on said distributed laws.

The gradation is a law imposed on the lighting network (1) by a gradation coordinating lamp. It consists of a table of states that defines the light power that must be distributed in the lighting network (1) according to the time sections.

Parameterization is a law imposed on the entire lighting network (1) by a coordinating lamp (LC). When a lamp (2) receives a global parameterization message, through a control organ for example, it automatically becomes the coordinating lamp (LC) of the parameterization.

From this moment, the coordinating lamp (LC) diffuses the parameters to the lighting network

(1) repeating them according to a law of increasing terms from the beginning of the night. All lamps (2) of the lighting network (1) are in fl uenced by the parameterization except for some lamps (2) that have been declared independent because they have been assigned a particular function such as lamps (2) responsible for lighting a pedestrian crossing .

Motion detection through the motion detection means of a coordinating lamp (LC) is used to raise the light fl ow at a particular place in the lighting network (1) so it only affects a group formed by a set of lamps (2) of the lighting network (1) and not all of it.

The distributed light measurement is used to make a decision to turn on or off the lighting system assembly (1).

-

Transmission of the order through the communication means (3) of said first coordinating lamp (LC) by means of a communication message to a second lamp (2) that is part of the lighting network (1) which in turn said second lamp

(2) retransmit the communication message through the communication means (3) of the same to a third lamp (2) and so on until completing all the lamps (2) that are part of the lighting network ( one).

Thanks to the mesh configuration of the lighting network (1), the transmission of the communication message over the entire network (1) is allowed by retransmission of the communication message from one lamp (2) to another lamp (2) ).

The principle of communication through communication messages may consist in assigning a random number to the communication message to be sent. This communication message number is valid until its complete transmission has occurred. The transmission is considered to have been completed when all the lamps (2), either those belonging to a group formed by a set of lamps (2) of the lighting network (1) or all the lamps (2) that they form said lighting network (1), they have received the message, since there will be occasions when an order affects a group formed by a set of lamps (2) that form the lighting network (1) and on other occasions, the order affects the entire lighting network (1).

At this time, when the transmission is terminated, the communication message number is abandoned. A timing limits in all cases the duration of the communication message.

The transmission of the messages takes place after a maximum period determined as the rest of the division of a pseudo random value by a prime number.

In order to avoid possible collisions between messages of different lamps (2), the media (3) detect a transmission in progress, if it is considered that the transmission is not feasible, the transmission period is redefined.

-

Receipt of information and treatment of it by each of the lamps (2) that form the lighting network (1) individually and action of each of the lamps (2) on their lighting status depending on the message of communication received by the coordinating lamp (LC) and depending on the lighting state in which each of the lamps (2) is located.

Once a lamp (2) has received a communication message, its lighting status acts individually and can be modified or maintained as it was before the reception of the communication message because said lamp (2) is not affected by the order issued through said communication message, for example, in the event that the communication message is directed to a set of specific lamps (2) and said lamp (2) is not associated with said lamp set (2). Therefore in this case the lamp (2) acts merely as a transmitter of the communication message.

One of the laws on which a coordinating lamp (LC) is based to modify a state of ambient lighting is the movement or presence of a body.

In this case it is necessary to modify the state of ambient lighting by raising the light fl ow in a given area of the lighting network (1), therefore, sometimes only a set of lamps

(2) that is part of the lighting network (1) has to modify its lighting status (understood as lighting status, the lighting status in which a lamp (2) was before the detection of the movement of a body).

In these cases, the norms that define the membership of a group formed by a set of lamps (2) of the lighting network (1) are defined.

These standards are defined through the detection means (4) of a coordinating lamp (LC) and determine the lamps in the lighting network that will act upon a received information message.

The relationship between the lamps (2) belonging to a group formed by a set of lamps (2) can be established according to a dependency law or according to a proximity law.

The dependency law is established by a routing table associated with the control means (6) of a lamp (2) that establishes which are the detection means (4) associated with a coordinating lamp (LC) that influence its operation .

Figure 3 shows a schematic of an example, in order to clarify the operation of this dependency law.

As you can see the lamp @ 2346 is influenced by the detectors (d1 and d2), the lamp @ 2345 is not influenced by its own detector but by the detector (d2), the lamp @ 2347 is influenced by the detector (d1) and finally the lamp @ 2348 is influenced by the detector (d2).

The proximity law indicates the distance in number of radio jumps from the detection means (4), in the example shown in Figure 4, the detection means (4) are formed by the detector d1.

In this example, the distance has been defined as d <= 1, therefore for a detection on d1 of the lamp @ 2347, the lamps @ 2346, @ 2345, @ 2348 are in fl uenced, however, the lamps @ 2349 and @ 2350, they are not.

It does not alter the essentiality of this invention variations in materials, shape, size and arrangement of the component elements, described in a non-limiting manner, this being sufficient to be reproduced by an expert.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement Of all the documents recovered from the state of the art, document D01 is considered to be the closest to the request being analyzed. The claims of the application are then compared with document D01. Claim 1 Document D01 describes a procedure for exchanging and processing information for a lighting network formed by a plurality of lamps (111) having communication means (501), control means (401), detection means (431, 461) and lighting means (321, 701) (see paragraphs 9 and 10), the procedure comprising the following steps: -Detection of a state of ambient lighting by means of a first coordinating lamp through the means of detection (431) of at least one lamp (111) of the lighting network. -Generation of an order in response to said state of ambient lighting by means of said first coordinating lamp through the control means (401) of said first coordinating lamp (see paragraph 255). -Transmission of the order through the communication means (501) of said first coordinating lamp by means of a communication message to a second lamp (111) that is part of the lighting network which in turn transmits said second lamp the message of communication through the communication means (501) thereof to a third lamp (111) and so on until completing all the lamps (111) that are part of a group formed by a set of lamps (111) that form the lighting network and / or to complete all the lamps (111) that form the lighting network (see paragraphs 96-104). -Reception of the information and treatment of it by each of the lamps (111) that have received the order through a communication message individually and action of each of the lamps (111) on their lighting status depending on the communication message received by the coordinating lamp and depending on the lighting status of each of the lamps (111). Following the analysis of document D01, the features described in independent claim 1 are disclosed by said document, so claim 1 does not meet the requirement of novelty according to article 6.1 LP. Claim 2 Document D01 indicates that the lighting network may have more than one coordinating lamp (see paragraphs 102, 103, 255, 256). Therefore, it can be concluded that, in view of the state of the known art, claim 2 does not meet the requirement of novelty according to article 6.1 LP. Claim 3 Document D01 indicates that the detection means (431) can belong to the coordinating lamp, to another lamp (111) of the lighting network or a set of lamps (111) of the lighting network (see paragraphs 116-118, 255). Therefore, it can be concluded that, in view of the state of the known art, claim 3 does not meet the requirement of novelty according to article 6.1 LP. Claim 4 Document D01 indicates that the generation of an order in response to said state of ambient lighting by means of said first coordinating lamp through the control means (401) of said first coordinating lamp is carried out as a function of distributed laws of the lighting network such as motion detection, light measurement and / or demand on or off (see paragraphs 104, 116-121). Therefore, it can be concluded that, in view of the state of the known art, claim 4 does not meet the requirement of novelty according to article 6.1 LP.  WRITTEN OPINION Claims 5 and 6 Document D01 indicates that at least one set of lamps (111) that are part of the lighting network acts on its lighting state by modifying this state or all of the lamps (111) that form the lighting network they act on their lighting state by modifying this state (see paragraphs 96-104, 255, 256). Therefore, it can be concluded that, in view of the prior art, claims 5 and 6 do not meet the requirement of novelty according to the article  6.1 LP. Claims 7-9 Document D01 indicates that the detection means of a coordinating lamp determine the lamps (111) of the lighting network that are to be modified by modifying their lighting state before a received information message (see paragraph 255). The detection means can act by means of a dependency law (see paragraphs 256 or 98) or by a proximity law (see paragraph 99). Therefore, it can be concluded that, in view of the known state of the art, claims 7-9 do not meet the requirement of novelty according to article 6.1 LP. Claim 10 The invention defined in claim 10 differs from document D01 in that the detection of a lighting state of a coordinating lamp when it receives the brightness values of a set of non-coordinating lamps that are part of the lighting network, is performed by calculating the average of the luminosity measurements received. However, it is considered that this solution would be obvious to a person skilled in the art who had to obtain a representative value for a measure from a set of measures; in this particular case, to obtain a lighting state from a set of luminosity measurements. Accordingly, claim 10 is deemed not to meet the requirement of inventive activity according to article 8.1 LP. Claim 11 Document D01 describes a lighting network that operates according to the procedure for exchanging and processing the information described in any of claims 1-10. Therefore, it can be concluded that, in view of the state of the known art, claim 11 does not meet the novelty requirement according to article 6.1 LP.
