Description

Improvements introduced in the systems Wireless communication

The present invention patent makes reference to the improvements introduced in the systems of wireless communication existing to date and whose essential characteristics will be described in detail in the Present descriptive report.

A wireless communication system, to which the improvements object of the invention have been applied, consists of one or several autonomous transmitter-modules that can be programmed to communicate with another or others externally powered receiver modules. The autonomy of each transmitter module is based on using the power supply electrical necessary for its operation, obtained advantageously and preferably of a generation / conversion mechanism that It replaces the usual batteries.

It is obtained and provided in this way the necessary and sufficient energy, in quantity and quality, to provide a low consumption radio frequency transmitter of the maximum versatility and freedom in terms of installation and use within the system of which it is part and, with it, of an authentic independence from the rest of the elements of an installation electric The maintenance issues are also canceled out, durability, replacement and disposal of the necessary up to date batteries or batteries

Regarding the module power supply or corresponding receiver modules, as part of the installation of action on connected loads, do not require of this autonomy and also need a greater amount of energy to operate, so they are fed so conventional from the existing power network.

State of the art

At present, the radio frequency wireless communication technology, in its low bandwidth variant, as an alternative to circumvent main drawbacks that arise from using cables as a means of transmission in control and management applications of electrical installations.

Among the numerous systems that make use of This technique can be distinguished from each other by the frequency of the radio wave used as a carrier of the content of the communication, by the information modulation method, by the type of protocol (proprietary or dedicated to standard), by the encryption method of messages or telegrams issued and for several other characteristics thereof, all This is well known to those skilled in the art.

In any case, however, all of them They share a common requirement: the power supply that they need to function they obtain it, either from a network of power of which they are part and to which they are connected, or of a battery or battery in cases where it is not possible connect the sending and / or receiving device to the power network, or maximum freedom and versatility is sought in the installation of the same.

One of the main problems and limitations of the systems that implement this second option, it is derived precisely from its dependence on the batteries, since the use of these conditions the useful life and operability of the device, in addition to forcing maintenance throughout its shelf life (battery depletion notice, replacement by one new and disposal of the depleted, etc ...).

It is therefore the basic objective of improvements object of the present invention, eliminate this last problem by replacing the mode of power currently used for the emitters of a system wireless, by means of batteries or batteries, by others that are energy independent.

Description of the invention

In the present invention some improvements applied to wireless communication, which they affect the system in the following sense:

The emitting elements are characterized because they obtain the energy for their operation from the energy mechanics provided at the time of its operation by means of a induction electric power generating mechanism electromagnetic as a preferred embodiment but not limiting

Thus, the improvements subject to the present invention, will allow the application of the mechanism generator cited in a set in which, next to it, contained a circuit of adaptation of the generated energy, a circuit of signal generation and control and, finally, a transmitter circuit signal

In order to describe in detail the basic elements of the improvements object of the present invention, some drawings are attached, by way of example non-limiting, in which:

Figure 1 is a schematic diagram of the different blocks that constitute the system;

Figure 2 is an exploded view of the set, indicating the location of the generator in lines discontinuous; Y

Finally, Figure 3 is a view in perspective of an actuation key, on its rear face, to show your acting lugs.

According to these drawings, the transmitter module assembly (1), inside which are arranged, as schematically shown in figure 1, the mechanism generator (2), the electronic adaptation circuit (3) of the generated energy, the electronic control circuit (4) and the radio frequency transmitter circuit (5).

On the appropriate cover (6) of the module (1), keys (7) are properly positioned and installed to be pressed at the time the system should be operated, as will be described below.

On the inside of the keys (7) are located stomping bumpers (7a) that are arranged on a appendix (2a) of the generating mechanism (2) and the tread lugs (7b), which are located on tabs (6a) that has the own cover (6).

Under these tabs (6a), and not visible directly in figure 2, micropulsors are located (8), which allow the selection of the channels of communication available.

When pressing manually or equivalently, one of the keys (7), the tracer (7a) pushes the appendix (2 a) of the generating mechanism (2) and at the moment of overcoming the resistance that this one offers the abrupt change of position that originates Electric power generation, essential feature of said mechanism (2).

Meanwhile, the small time interval t_ {r} that this process takes, is enough for the other button (7b) of the activated button (7) is already pressing, through one of the tabs (6a) of the cover (6), the micropulsifier  corresponding (8), so that the channel corresponding to the key pressed is already preselecting at the time of produced and used generated energy.

The latter is crucial for the right one. operation of the emitter since the energy obtained would dissipate and it would be irretrievably lost if it is not taken advantage of immediately after its generation, by the generating mechanism (2).

For the message to be issued, produced with Each mechanism drive, meet all the features of reliability, scope, etc ..., required, the electronic circuit control (4) and radio frequency (5) have been designed to minimize your energy consumption, since precisely energy is the scarce and limiting resource of any process.

In a system equipped with improvements object of the present invention, orders of On and off of electric charges, electronic regulation of the same, timing, and the like.

This is possible thanks to the presence of the generating mechanism (2) that generates energy, useful for issue a message or telegram, both during the "race of drive "which will be called T1, as the return to its  initial rest position (called T2).

Equally helpful in this regard is the possibility to preselect one between two or more channels of communication by means of one of the micropulsors (8), which in the drive process of the generator mechanism (2) is activated an instant before the generation of energy and remains so until after an instant after the end of the complete cycle with the return of the generator mechanism (2) to its original position.

Each of these channels is associated uniquely, in the manufacturing process of each module, with one of the numerous codes available.

The total number of these codes and therefore, the of uniquely associable channels, depends on the number of bits that contain the message or telegram to send.

For example, with 32-bit telegrams you it would have a total of 2 32 different channels.

In this way the receiver is programmed corresponding to interpret different orders depending on of the preselected channel and the time between reception of both telegrams, T1 and T2.

Summarizing what was described above, the special arrangement of the different elements that make up the system, allows to act as follows:

to)

To the pressing one of the keys (7) occurs first, through  of the tongue (6a) of the cover (6), pressed by the pin (7b), the closure of the corresponding micropropeller (8) and, consequently, the selection of one of the available channels.

b)

To the At the end of its journey, the button (7a) of the button (7) has actuated on the appendix (2a) of the generating mechanism (2), producing the energy necessary for the generation and emission of T1 telegram corresponding to the preselected channel through the emitting element

C)

To the cease pressure on key (7) automatic return action of the generating mechanism (2), to its initial stable position, returns to  general by the same procedure, the same amount of energy which is also used for the generation and issuance of a second telegram T2, corresponding to the same channel, since this it remains still preselected when the micropulsifier (8). An instant later, upon retrieving the key (7) its initial position, the tongue (6a) stops pressing the micropulsador (8) leaving the channel released.

d)

Yes T2 is received by the receiver before a period of preset time t from receipt of T1, this interprets which has to switch the state of the load it controls (turn it off if is on and turn it on if it is off).

and)

Yes on the contrary, T2 is received with a delay with respect to the T1 reception greater than t, the scheduled interpretation will be that the commanded load must be regulated in a preset direction (for example, increasing the intensity of it) or to be keep powered in a preset sense too (like it would be, for example, the case that the load was a motor of blind activation) until the arrival of the T2 telegram, moment in which both actions would cease.

Likewise Other functions such as the timing, activation of a predefined sequence or any other imaginable by controlling the two telegrams to receive and the time between them.

Described sufficiently the object of the present invention, it is indicated that its essentiality will not be altered for changes in shapes, dimensions or design, as well as in characteristics of the various system components, remaining said essentiality summarized in the following claims.
