System for the remote control of the radiation beams of multi-beam antennas.

OBJECT OF THE INVENTION

 10

The following invention, as expressed in the statement of the present specification, refers to a system for the remote control of the radiation beams of multi-beam antennas, whose object is framed within the field of antenna control, and describes a mechanical / electronic system for the remote control of the radiation beams of a multi-beam antenna. fifteen

Thus, the system consists of two distinct parts: i) the modular mechanical movement transmission part and ii) the electronic control part that governs the mechanics, both can be integrated inside the antenna and accessible to the end user.

 twenty

The mechanical system, which in the materialization of the present invention is internal, modular and accessible, allows to configure the tilt of each antenna band separately both manually and electrically, with the possibility of individually extracting each motor without disassembling the antenna, without affecting the position of the tilt and leaving visible to the user at all times the actual position of the tilt. 25

The electronic control system, which in the materialization of the present invention is internal, modular and removable, allows the control of the tilt of each band by one or several control entities in a totally independent way, without interfering with each other, and without the need to include any additional elements. 30

SCOPE.

This report describes a system for the remote control of the radiation beams of multi-beam antennas, being applicable in the field of mobile phone antennas, more specifically in that of multi-beam antennas that include control remote beam forming, widely known as beam shaping in English.

This invention has its maximum use according to the representation and concrete materialization shown in the figures, where both the electronic and mechanical system are internal to the antenna, modular and removable; installed on sharing antennas, a term widely known in the literature as "site-sharing" in English, where several mobile phone operators share the same antenna that includes several radiating systems.

BACKGROUND OF THE INVENTION

 5

Conventionally, the beam-shaped antennas are used in particular in mobile telephone base stations, where their best known field of application is the remote configuration of the inclination angle of the main or tilt beam by adapting RET (Remote Electrical Tilt) devices ) to the antenna.

 10

These antennas allow network operators to tilt the direction where the main radiation beam of the antenna points from a remote control center without the need to physically tilt the antenna. The electric offset is achieved by electromechanical actuation of internal elements of the antenna that modify the phase of the signal delivered to each radiating element (elements widely known as phase shifters or phase shifters). The radiation pattern on the coverage surface is superior in quality by achieving the inclination of the main beam through the electric offset than if the antenna was mechanically tilted. In addition, when doing this operation by means of individualized drives per band, each band can have a different inclination despite being assembled on the same mechanical structure. twenty

In the field of mobile telephony, multi-beam antennas are widespread. In the present invention we refer interchangeably to multi-beam or multiband antennas, understanding as such antennas that incorporate more than one radiant system within the same radome; for example, a dual-band antenna can have two radiant systems 25 in the bandwidth 1710-2690MHz; or a dual-band antenna can have a radiating system in the 690-960MHz spectrum and another radiating system in 1710-2690MHz; A hexa-band antenna can have two radiating systems in the 690-960MHz spectrum and 4 four radiating systems in the 1710-2690MHz spectrum, and so on. Each radiant system can work in several subbands; For example, a radiant system that covers the spectrum of 1710-2690MHz can be used in the sub-bands GSM1800 (1710 - 1880MHz), PCS1900 (1850 - 1990MHz), UMTS2100 (1920 - 2170MHz), TDD Band 40 (2300 - 2500MHz ), 3G-LTE Extension 2500 (2500 - 2690MHz), etc. Hereinafter we refer to multiband antennas when within a single radome or envelope there are several radiating systems, and where each band is referred to as a radiating system. 35

Multi-band antennas are increasingly demanded by mobile phone operators for several reasons: i) on the one hand they allow the operator to deploy a new technology by replacing old single-band antennas with multi-band antennas without the need to search for new locations, with the consequent cost savings of 40 bidding permits to deploy the new network technology, as well as saving operational and operating costs; ii) they allow several operators to share the same location by sharing the antenna, each of the operators having their bands completely independent of the rest of the operators, while sharing costs in permit tenders. Four. Five

In the market there are already multiband antennas where the radiation beam can be controlled independently by installing external remote control devices in each of the bands, or at least in the bands in which their control is necessary

constant for network optimization. Today, network operators are increasingly demanding that these devices be internal to the antenna for a triple reason: i) if the RET is external and is connected to the antenna at the time of installation of the antenna at the site , the RET is prone to shock failures at the time of installation; ii) If the RET is not placed on the antenna at the time of installation at the site, then the RET must be connected, and normally the 10 skills required for the RET installer and integrator at the base station are not the same skills required as for an antenna installer; iii) the operator prefers that the RET be factory installed by its manufacturer to avoid configuration errors. Therefore, although the internal incorporation of these devices could in the first instance entail a higher cost for the antenna than the fact of installing only RETs in the desired bands, in the whole of the installation it may not be so .

The requirements demanded by network operators for antennas with internal RET are: i) that it is capable of field replacement in an active location without the need to uninstall the antenna; ii) that it is capable of manually configuring the tilt of each band by the antenna installer, who ideally should not need more tools than those necessary for the installation of the antenna on the mast; iii) that the tilt configuration is visible at all times by means of a marker; iv) it is flexible for sharing sites between several mobile phone network operators. 25

In multiband antennas it is necessary to incorporate an independent mechanism for the control of the beam of each one of the bands, as well as to provide the necessary mechanisms to make the maximum control of the beam of each band in case of sharing between several operators or several base stations. 30

There are currently antennas that incorporate technology similar to that of the present invention, but lack some exclusive features of it:

- The solution adopted in patent application MX2010008830 (A) incorporates an internal system but not completely accessible as proposed, since the internal part of the mechanical system cannot be accessed. In addition, it has a disadvantage that this invention does solve, such as the fact that it is not possible to remove or replace a damaged motor without disassembling the antenna.

 40

- Patent application MX2010008830 (A) allows manual operation of the mechanical system, but always disengaging the corresponding motor. However, in the case at hand, it is not necessary to disengage the motor to manually operate the system and it is independent of whether or not there is electronics inserted or of the existence of power supply failures. Four. Five

- The patent application MX2010008830 (A) guarantees that during the manual operation of the system the mechanical transmission between the system and the phase shifters is kept connected, keeping the tilt and its respective indicator in the

position I had. However, in the case of having to replace one or more 5 motors it is necessary to disassemble the antenna and break that transmission, therefore that functionality is lost in a case in which the proposed invention would still be effective.

- Patent EP2668693 B1 shows a device for shaping the beam into a multiband antenna, with only one control interface for all bands, which makes it impossible to share this antenna with the electronic equipment of several operators.

- Patent DE102011015551 B4 shows a supplementary device for adding to shared sites, but it is not located or included within the radome of the antenna nor can it be considered as part of the internal RET. With the present invention it is not necessary to incorporate any external or additional element to enable antenna sharing between several operators.

 twenty

- US8860334 B2 patent shows a system for the control of a multi-band antenna, where it is only contemplated that the control board incorporates a receiving port to receive commands from the base station and a serial port. In the present invention, several control interfaces for antenna sharing between several base stations are incorporated with complete independence. 25

- US8860334 B2 patent shows a system for the control of a multi-band antenna where several motors cannot be moved simultaneously to control the beam of several radiating systems simultaneously, even by connecting a location sharing system according to DE 102011015550 B4 . 30

DESCRIPTION OF THE INVENTION

A memory system for the remote control of the radiation beams of multi-beam antennas is described herein, so that the internal system to the modular and scalable antenna comprises:

 a mechanical means based on at least one transmitter module of the rotation movement of a motor-reducer to a linear movement required by phase shifters that make up the antenna and whose transmitter module of the rotation movement is formed by: 40

or a modular bench group, anchored to the antenna frame, and;

or a motor group, removable and accessible from the bottom of the antenna, where in the absence of rotation of the axis of the motor-reducer the adjustment of the beam can be carried out manually by operating a spindle, 45 offering at all times the tilt indication sheet reading the actual position of the antenna tilt, and;

 5

 electronic control means that governs the transmission modules of the turning movement, capable of connecting to several independent control entities for independent control of each beam through the transmitting modules of the turning movement, where the allocation of bands by Control interface is flexible and configurable, comprising: 10

or at least one housing group, and;

or a removable cartridge connected to the housing group,

so that the transmitting modules of the motor-reducer's turning movement and the electronic control means are communicated by means of respective cables connected in connectors.

The modular bench group consists of an engine bed, a threaded spindle, a nut-carriage, a threaded spindle clamp plate, a first clamp plate screw, a threaded spindle pinion, a lock washer, about Rapid end-of-race rivets, a limit switch microswitch, a tilt indication blade, a phase shifter push rod and a few seconds fastening bolts of the indicator bar / foil.

 25

The motor group consists of a motor-reducer, an intermediate pinion, a second pinion of the axis of the motor-reducer, a motor cover and a third connecting bolts of the motor-reducer with its cover.

The third connecting screws of the motor-reducer with the motor cover allow the entire motor group to be closed to make it a replaceable block.

The rotation of the motor-reducer drives a gear mechanism by moving the torque of the motor shaft to the intermediate pinion and this in turn to the first pinion of the spindle, transforming the circular movement of the motor-reducer into the linear movement required by the phase shifters by means of the spindle mechanism - nut mounted.

When the motor shaft and the spindle move away by means of an intermediate pinion, the gear reducer can be removed or placed without releasing any pinion and without affecting the connected part of the phase shifters. 40

After the motor group has been removed, the spindle-nut assembly is still mounted with the tilt grade indication sheet and attached to the phase shifter push bar, allowing manual actuation on the spindle shaft part that stands out, maintaining its functionality even No engine installed. Four. Five

The system incorporates one or more limit switches that allow the motor-reducer to be calibrated, identifying its position relative to the limit switch without the spindle-nut assembly being forced at the ends of its travel.

On the other hand, each removable cartridge is formed by a control interface module and a control block, whose modules may or may not be printed on the same printed circuit board or not. In a practical execution they are constructed in two differentiated plates for greater flexibility, but it could also be in the same plate.

In addition, the control interface module contains one or more control interfaces.

 fifteen

In a practical embodiment, each control interface module consists of an 8-way circular connector and an 8-way female circular connector, although it can adapt any type and number of connectors.

The control block consists of a control electronics module, a 20 power control module and motor driver circuits.

The motor driver circuits are electrically connected to the motors through a connector that connects the housing group with the removable cartridge and in turn through the motor connectors. 25

The control block assigns any motor to any input interface, ideal condition for sharing antennas where there is no restriction to assign to each operator the band that you want to control.

 30

Likewise, the control electronics module has the capacity to manage at the same time the data flows that arrive from each control entity in a totally independent way.

The control electronics module interprets the commands that arrive through each control interface and activates the control signals by activating the motor drivers.

The power supply electronics module receives the voltages from each control interface, and after passing through lightning and surge protections, and after conveniently transforming them to the necessary values for the installed motors, 40 attacks with the voltages and currents to the motor drivers, and, likewise, the power control module also provides the supply voltage to the electronic control module.

Each motor driver acts on each motor. Four. Five

On the printed circuit board, present in the "housing group", a block 5 of motors is implemented that only contains the necessary connectors to connect the different "motor group" necessary for each antenna model.

Each connector of the motor block comes out of a cable that connects to one of the removable motors through the connector enabled for it, by means of which the voltage and current necessary for the rotation of the motor is provided.

In order to complement the description that is going to be carried out below, and in order to help a better understanding of the characteristics of the invention, the present descriptive report is accompanied by a set of drawings, in whose figures illustratively and not limiting, the most characteristic details of the invention are represented.

DESCRIPTION OF A PREFERRED EMBODIMENT. fifteen

In view of the aforementioned figures and in accordance with the numbering adopted we can observe how the present invention describes a system for the control of the radiation beams of a multi-beam antenna, which is internal, modular and scalable for mechanical control. Electronic beam of a multi-beam mobile phone antenna. twenty

The system comprises two fundamental parts: a mechanism that transmits the linear movement required by the phase shifters and an electronic control means that governs the previous mechanism.

 25

As can be seen in figures 1a, 6a and 5, the electronic control means is identified with the letter "A" and the mechanical means with the letter "B", so that in figure 6b the electronic system is detailed. It consists of a “housing group” (III) that is mounted in all cases on the antenna and that houses a connector where a “removable cartridge” (IV) is connected in the necessary cases. 30

On the other hand, in Figure 1d it is shown that the mechanical system that is formed by a “modular bench group” (I) that is anchored to the antenna frame and that may or may not contain, depending on the chosen model, a “group motor ”(II) fastened by fourth screws 1. 35

Both sets (mechanical and electronic) are communicated through cables that allow easy connection and disconnection when replacing the motors.

Turning to analyze in more detail the mechanical means, it can be seen in Figure 1d that the main advantage of the invention is precisely this ability to extract or place the motor group (II) in its housing of the modular bench group (III), with the simple action of removing the two fourth screws 1 and loosen their corresponding cable.

Figure 3b shows the components of the motor group (II), defined by the motor reducer 45 14, the intermediate pinion 15, a second pinion 16 of the axis of the motor reducer 14, a cover 17

of the motor reducer and third screws 18 connecting the motor reducer 14 with the cover 17 5 thereof. Said third screws 18 screws, once the intermediate pinion 15 and the second pinion 16 of the motor-reducer shaft 14 are inserted into its housing of the cover 17 of the motor-reducer and of the axis of the motor-reducer, allow this subset to be closed so that It becomes a single replaceable block.

 10

The operation of this subset is simple, when the gearmotor 14 rotates, it drives the gear mechanism, moving the torque to the intermediate pinion 15. In the event that the gearmotor 14 was mounted on the bench and there was an electrical breakdown or the orders of the electronic control means simply did not arrive, the interior could be accessed (through an opening in the outer cover of the antenna) and act directly and 15 manually on the part of the hexagonal axis of the protruding motor-reducer 14 (using a regular socket wrench) and this would keep its functionality intact.

Figure 2b details the assembly of the modular bench group (I), which consists of the bench 2 of the motor reducer 14, a threaded spindle 3, a nut-carriage 4, a clamping plate 5 for the 20 threaded spindle 3, a first screw 6 of the clamping plate 5, a first pinion 7 of the threaded spindle 3, a lock washer 8, quick rivets 9 of the limit switch, a microswitch 10 end of stroke, a tilt indication blade 11, a bar 12 push-pull of the phase shifter and third screws 13 for fixing the indicator bar / sheet.

 25

The design of this subset of the modular bed (I) is basically a mechanism for transforming the circular movement of the motor-reducer 14 into the linear movement required by the antenna phase shifters. This transformation is carried out by means of the screw-nut mechanism 4 that is mounted, but to this basic function other improvements made by the present invention are added. 30

One of them, by moving the axes of the motor-reducer 14 and the threaded spindle 3 away by introducing an intermediate pinion 15, is that it leaves enough distance between them so that the motor-reducer 14 itself can be removed or placed without releasing no pinion and without affecting the part connected to the phase shifters. 35

Once the motor group was removed, the 4 would continue to be mounted, with its respective tilt indication sheet 11 and attached to the push bar 12 of the phase shifters, allowing manual action on the part of the hexagonal axis of the threaded spindle 3 that protrudes (using a socket wrench), maintaining its functionality even without motor-reducer 40 14 installed. Another important feature of this system is that it incorporates a microswitch 10 of the limit switch, which allows the motor-reducer 14 to be calibrated, identifying its position without the spindle-nut assembly being forced at the ends of its travel.

Figure 4 shows that this modular mechanical system allows several 45 units per antenna to be mounted in very little space and completely independent to be able to repair, act manually or even not mount any of them without affecting the rest of the system.

Figure 5 shows how said mechanical system is accessed inside the antenna through an opening in the general cover, which can be closed with its corresponding small additional cover.

The electronic or electronic control system represented in FIG. 7 is composed of three differentiated blocks that in practice are implemented in three printed circuits 10 for flexibility and modularity: the control interface block 100, the control block 110 and the block of engines 120.

Thus, said block 7 shows a block diagram of the electronics associated with the internal multiband RET, consisting of a control interface module 100, a control module 110 and the motor connection module 120. The interface module Control consists of 25 one or more 20i interfaces. The control module 110 contains the control electronics module 25, the power control module 26 and the motor drivers 27i. The control electronics 25 have the function of managing communications with each and every one of the control interfaces 20i complying with the communication protocol of each of them, and generating the relevant control signals towards the motor drivers 27i according to the Commands received The control of supplies 26 has the function of generating the supply voltage 27 of the control electronics module 25 and the supplies to the motor drivers 27i. The drivers of the 27i engines have the function of activating the relevant signals to initiate the rotation of the 28i motors in the proper direction or ordering their braking and stopping, according to indications received by the control electronics 25.

The control interface block 100 contains the necessary connectors to connect with the control entities. The most common is that the control entities are 30 mobile phone base stations, but it is not limited to them. Any other system with appropriate software to send beam shaping commands can also act as a control entity. The control interfaces 20 consist of connectors that provide power supply and control data to the electronic module of the RET. 35

Currently, the most widespread is that these control interfaces 20 consist of two 8-way circular connectors in accordance with IEC 60130-9, as established by the AISG standardization group in versions 1.1 and 2.0, and as drawn in Figure 6a. However, this invention is not limited to this type of connectors and pinout 40 defined in these recommendations, but is open to contemplate any type of connector and physical level.

In the case of following the AISG and 3GPP recommendations, where each interface has a male input connector and an output female connector for cascading 45 of several devices in line of antenna ALD (Antenna Line Devices), in the embodiment In practice of this invention, the control interface block is responsible for carrying the signals from one connector to another to implement the cascade bus, making the rest of the modules independent of this functionality. However, this simple functionality can also be done by other simple means and is not limited to being implemented on the board 50

of control interfaces. 5

Control block 110 consists of a control electronics module 25, a power control module 26 and motor driver circuits 27i. The control block has the fundamental functions of:

 10

i) communicate with each of the control entities completely independently of the rest, interpreting the commands received to order the movements of the motors that move the tilt adjustment mechanism, and at all times fulfilling the necessary timings for a correct communication ;

 fifteen

ii) manage the supply voltages of the motor drivers (DMi), so that an engine is only powered by the controlling entity that governs it and not by any other;

iii) order the start of rotation, direction of rotation and brake / stop of the motors, ensuring their correct position for the tilt to be configured.

The architecture of the control block 110 offers total flexibility to assign any motor 28 to any input interface 20, an ideal condition for sharing antennas (site sharing) where there is no restriction for assigning to each operator the band that 25 wishes to occupy.

Figure 8 shows a practical example of using the internal RET object of this invention. In the example, the antenna consists of 6 different radiating systems 30i, where each radiating system consists of a phase shifter whose movement is caused by a motor connected to its corresponding connector 28i. In the example, this antenna is controlled by three independent control entities 20j. The control entity 201 controls the bands 301, 303 and 306, the control entity 202 controls the bands 304 and 305, and the control entity 203 controls the bands 302.

 35

Likewise, as indicated, it shows three control entities 20 that distribute six radiant systems 30, all housed within the same radome. This assignment is done by software programming (write assignment of bands in EEPROM memory), and can be reprogrammed at any time.

 40

The control electronics module 25 has the capacity to simultaneously manage the data flows that arrive from each control entity 21i in a completely independent manner. In the same way, if for some reason the communication with one of the control entities failed, the rest would not be affected and would continue to function normally. The control electronics module 25 interprets the commands that arrive through each control interface 20i and activates the control signals 23i by activating the motor drivers 27i. Currently, the AISG1.1 / AISG2.0 standards and 3GPP recommendations that define both physical, link and application levels are massively extended

ensuring the interaction between the control entities and the RET devices of any manufacturer. In the realization of this invention, the above-mentioned standards have been implemented, achieving excellent results.

The power control module 26 receives the voltages coming from each control interface, and after passing through lightning and surge protections, and after 10 transforming them conveniently to the necessary values for the installed motors, attacks with the voltages and currents 24i to the 27i motor drivers. The power control module 26 also provides the supply voltage to the electronic control module 25.

 fifteen

Each motor driver 27i has the possibility of acting on each motor 28j. It is the software configuration that assigns at each moment which driver 27 will control each motor 28, so that there can be no signal collisions 29ij and only one driver 27 will control a certain motor 28.

 twenty

The engine block 120 consists of as many connectors 19b as bands the antenna has. From each connector 19b of the motor block, a cable is connected to one of the removable motors through the connector enabled for it 19a, by means of which the voltage and current necessary for the rotation of the motor are provided. Also present in this connector is the sensor signal of the motor that indicates its status and its relative position with respect to microswitch 10 of the limit switch.

By way of synthesis, encompassing everything proposed and due to its design, this invention provides the following advantages:

 30

 System fully integrated inside the antenna, being protected against external agents and allowing a more compact and robust overall antenna design.

 Modular and flexible system, adaptable and automatically expandable to any antenna regardless of the number of radiating systems it integrates.

 Motors individually accessible and removable from the bottom of the antenna, without the need to uninstall the antenna from its location. This feature is the most important advantage from the mechanical point of view, since it allows replacing any individual engine that has failed without affecting the operation or assembly of the others. This reduces the cost of a possible maintenance and spare parts management operation, allowing the company and the user to solve possible problems arising from a specific engine at the installation site, without having to replace the ones that work 45 correctly. In this way, the client is also allowed to acquire an antenna with the flexibility to select the engines initially installed at the factory and later, and without disassembling or affecting the rest of the systems, installing the groups

necessary engine acquired in later phases. 5

 Possibility of manually modifying the system to vary the tilt of each band separately, with or without its geared motor (also with or without connected electronics). This advantage ensures that it is always possible to manually modify the tilt of each band separately, regardless of whether or not there is communication 10 with a control center.

 When replacing a motor-reducer, the mechanical transmission between the system and the phase shifters is not disconnected, which allows the tilt and its respective indicator to be maintained in the position it had. This feature facilitates the replacement or incorporation of 15 motors at any time, without affecting the position in which the tilt of each band was placed.

 The gearmotors are connected with connectors (without welding), allowing the connection or disconnection of them at any time without the need for 20 complex tools.

 Modular system that allows mounting individually or in groups of several units depending on each antenna model. This characteristic implies that each unit of the mechanical bed system plus individualized motor group is mounted on each band, adapting exclusively to the number of bands of the antenna and without the need to mount any additional multiple housing.

 Being modular and easy to assemble, it allows you to buy the antenna with only a few engines initially installed and then incorporate the remaining ones, as well as with or 30 without electronics in place. This feature allows to create an a la carte range of antennas in which some carry all the engines initially installed and others only some, at the customer's choice, also having in all cases the possibility of modifying the tilt of each band separately.

 35

 It incorporates a limit switch that indicates to the engine the end of its travel. This feature ensures that the motors will never block the phase shifting system by physical limit and can be calibrated to know their position at any time.

 40

 Lightweight and reduced cost system (plastic housings and gears). The design of the set allows to use plastic materials and therefore reduce both in weight and in cost the structure of the system.

 Electronic system accessible and removable from the bottom of the antenna, which allows the replacement of the antenna in case of electronic breakdown without the need to uninstall the antenna from its location without causing a cut in the network service

 5

 This modular and accessible electronics allows the acquisition of the antenna without remote tilt control functionality, and its update in later phases of network deployment or optimization

 The electronics have a flexible control interface module, so that as many control interface connectors can be placed as independent control entities share the radiating antenna systems. This allows antenna sharing by several operators without the need to integrate any additional external device

 fifteen

 The electronics carry out the management of motor feeds equally, so that each motor is only powered by the controlling entity that governs it, without consuming current from or harming the rest of the control entities 35

 Fully flexible electronics, so that the bands / motors governed by each control entity can be assigned by software 20, ensuring the absence of collisions

 The allocation of bands by control entities can be done at any time during the life of the antenna, without the need for its removal from the site.

 Modular electronics, capable of independently managing all communication flows of the control entities, tested according to AISG2.0 and 3GPP standards of several manufacturers of mobile phone base stations. In the event that a communication flow is interrupted for any reason, it does not interfere with the rest of the interfaces
