"Method and system for increasing the autonomy of a radio transmitter-receiver device, and radio transmitter-receiver device with great autonomy."
The present invention relates to a method for increasing the autonomy of a radio transceiver device as well as to a system implementing such a method. It finds a particularly interesting application in the field of collecting data from water meters. However, it also applies to the collection of data from other energy meters such as gas, electricity or heat meters. However, the invention is of a broader scope since it can be applied to the transfer of data from sensors and devices for measuring physical quantities such as vibrations, stresses, temperatures for example.

 In general, deregulation and privatization in the field of water, gas and electricity require producers, distributors and energy managers to improve the quality of the service provided to users, to reduce costs in order to maintain or develop their market share.

Currently, most of the energy meters used require the movement of an operator to the place where the meter is installed for manual sampling on site.

 Water remote reading systems are known for example using radio transmitters supplied by the sector. However, power supply by sector is still not available and can also pose the problem of billing the subscriber for the electricity consumed by radio transmitters. To do this, it

<Desc / Clms Page number 2>

 battery-powered transmitters exist that operate on sleep and wake cycles to limit energy consumption. Such a transmitter wakes up periodically to detect a request or a message relating to it. This is the principle of windowing in reception ("reception polling" in English).

 Generally, the frames sent consist of a preamble or header ("pre-header"), followed by the data to be transmitted. For example, the preamble consists of a series of successive 0s and 1s, issued at a fixed transmission rate. The duration of the preamble is greater than the windowing period consisting of a sleep phase and a phase of listening to the transmission channel. Thus, we are sure to have an overlap zone between a listening phase and the preamble.

Depending on the signal detected during the listening phase, the equipment initiates the complete data reception process and responds to the request or returns to its sleep state. Such a method is for example implemented in the Mbus radio protocol.

 However, such a protocol has many limits: - the transmissions being asynchronous, the recipient equipment does not know the moment when the data is available; thus at the end of the listening phase and when a preamble has been detected, the complete reception process begins with a data waiting phase. The duration of this waiting phase is linked to the occurrence of windowing relative to the preamble; in particular, if the occurrence takes place just at the start of the preamble, the recipient material must wait for the complete duration of the preamble before having access to the data; the material therefore consumes

<Desc / Clms Page number 3>

 energy unnecessarily for a time which can last several seconds; - when several radio devices are in range, the sending of a message to a particular device will be interpreted by all the devices and will have the consequence of triggering the complete process of receiving all the devices; materials not affected by the message consume unnecessarily; this untimely implementation or awakening phenomenon has irreversible consequences on the overall performance of the products, for example a reduction in autonomy in considerable proportions, depending on the architecture of the network.

 The object of the present invention is to remedy the aforementioned drawbacks by proposing a communication protocol minimizing the consequences of untimely awakening and, therefore, in particular of optimizing energy consumption.

 The invention also aims to improve the quality and quantity of the service provided by a remote reading company.

 The above objectives are achieved with a method for increasing the autonomy of a plurality of radio transceiver devices operating in a network and according to a standby mode and an active mode. The standby mode consists of a periodic alternation of a sleep phase of low consumption and a listening phase for the detection of an incident signal.

During active mode, the transmitter-receiver device, connected to at least one energy meter or sensor, is capable of receiving commands and transmitting data relating to the energy consumption measured by this meter or relating to a

<Desc / Clms Page number 4>

 physical quantity measured by this sensor. The incident signal includes a preamble followed by a data frame. According to the invention, information intended for the implementation of the active mode of at least one given transceiver device is introduced into the preamble of the incident signal, in order to allow transceiver devices not concerned by the incident signal immediately return to standby mode, thus avoiding an extended listening phase.

 On the one hand, when a transceiver device in the listening phase detects the preamble of an incident signal, it remains in the extended listening phase until the detection of said information, analyzes this information, and returns in standby mode if the incident signal is not intended for it. And on the other hand, when a transceiver device in the listening phase detects the preamble of an incident signal, it remains in the extended listening phase until the detection of said information, analyzes this information, and initiates an active mode process if the incident signal is intended for it.

 According to an embodiment of the invention, the active mode process can consist in remaining in the listening phase until the reception of the data frame during which the device is in active mode. However, according to another preferred embodiment of the invention, the active mode process can consist in returning to the sleep phase during the preamble and then in activating the active mode when the data frame is received. . To do this, the transceiver device comprises means for ensuring synchronization with the preamble of the signal.

<Desc / Clms Page number 5>

 incident so as to initiate a sleep phase until the start of reception of the data frame.

 With the method according to the invention, radio equipment is not obliged to wait for the arrival of the data frame to know whether the data is intended for it. Thus the equipment not concerned can quickly return to the waiting phase while saving the batteries supplying them. We therefore optimize the energy consumption of each radio device, which increases their autonomy. To ensure the occurrence between the information and a listening phase of a device, the information is introduced repeatedly or preferably periodically in the preamble of the incident signal and the duration of transmission of this information is ensured. information is less than the duration of the listening phase. In addition, the information is transmitted at a speed greater than or equal to the transmission speed of the other bits of the preamble.

 For example, for a preamble consisting of alternating sequences of 0/1 or 1/0 at a speed of 2400 baud, we integrate the information in the form of a 16-bit binary number transmitted at a speed of 9600 baud every eight alternating sequences of 0/1 or 1/0. Preferably, the information comprises a predetermined number of least significant bits of the address of the transceiver device concerned.

 According to an advantageous embodiment of the invention, the information also comprises bits for testing the consistency of this information.

 It can also include functionality bits intended to activate predetermined functions within the relevant transceiver device. These functions may consist of

<Desc / Clms Page number 6>

 a measurement of the power level of the incident signal so as to allow the development of a response strategy accordingly. For example, a redundancy of responses or even a refusal of response when the power is too low, by disturbing the transmission channel. Depending on the elements contained in the information, it is also possible to initiate a long-term sleep phase or even generate a priority response signal.

des moyens pour détecter, au cours d'une phase d'écoute, le préambule du signal incident de façon à maintenir cette phase d'écoute, des moyens pour détecter, au cours de cette phase d'écoute maintenue, une information incluse dans le préambule du signal incident et transmise à une vitesse supérieure à celle des autres éléments du préambule,

From a device point of view, the transceiver can advantageously include:

means for detecting, during a listening phase, the preamble of the incident signal so as to maintain this listening phase, means for detecting, during this maintained listening phase, information included in the preamble of the incident signal and transmitted at a speed higher than that of the other elements of the preamble,

means for analyzing information, and means for entering the extended listening phase until the reading of a data frame, for returning to the standby mode or for entering the sleep phase until the arrival of a data frame, depending on the elements included in said information.

 This device may also have means for connection to at least one sensor, in particular a pulse energy meter, counting means for counting pulses coming from this pulse counter, and means for diagnosing the wear of the batteries. the feeding.

 According to another aspect of the invention, a system for reading network data from a plurality of energy meters by radio waves is proposed, implementing a protocol according to the method described above. According to the invention, the system comprises: - a radio transmitter-receiver device connected to at least one energy meter, a concentrator for managing a plurality of radio transmitter-receiver devices according to the protocol, a supervisor for managing a plurality of concentrators , this supervisor being able to directly manage at least one transceiver device, and a central station for managing at least one supervisor.

 With such a system, automatic readings can be made. Wiring problems are avoided, which considerably simplifies installation and maintenance and reduces costs per meter. Obviously, on-site tours become exceptional, so no disturbed customers. This system offers many services such as deleting estimated invoices or even detecting leaks. Preferably, the communication protocol between the different elements is bi-directional and includes processes for acknowledging the messages transmitted. The system can include a GSM or telephone network connection between the central station and the supervisor.

 Advantageously, the central station can include means for detecting the wear of the batteries supplying the transceiver devices.

 Other advantages and characteristics of the invention will appear on examining the detailed description of a mode of implementation in no way limiting, and the appended drawings in which: - Figure 1 is a schematic view of a system according to the invention; - Figure 2 is a diagram illustrating the signals transmitted by a concentrator and the reception protocol of a transmitter according to the prior art; and - Figure 3 is a schematic diagram illustrating the signal transmitted by a concentrator according to the invention and the reception protocol implemented in two transceiver devices according to the invention.

 Referring to Figure 1 we will now describe the architectural diagram of a remote reading network according to the invention. The system according to the invention implements wireless communication between a transceiver 6 or 7 connected to meters 8, 9, 10 or 11 and a supervisor 3, this system constitutes an automatic network for remote reading of meters ( in English, AMR for Automatic Meter Reading). The meters 8 to 11 are for example water meters. A transceiver 6 or 7 can control two water meters such as a cold water meter and a hot water meter. Supervisor 3 can also be in communication with type 6 or 7 transceivers (not shown in the diagram).

However, given the range of the equipment and for reasons of efficiency, concentrators 4 or 5 are interposed between the supervisor 3 and the network transceivers. These concentrators 4 or

<Desc / Clms Page number 9>

 5 play in particular the role of repeater and multiplexer.

 The supervisor 3 is in contact with a remote central station 1. This central station 1 can be a microcomputer equipped with conventional means of remote management of a transmitting network.

 The link 2 between the supervisor 3 and the central station 1 can be a GSM wireless link or a wired link through the switched telephone network.

 Each counter 8, 9, 10 or 11 is a pulse counter. The transceiver 6 or 7 records the amount of water consumed by memorizing any pulse from the meters under its control.

 The transceiver 6 or 7 is of the low power radio frequency type according to standard EN300-220 and equipped with standard interfaces (ILS switch with reed type contact) for connection with two meters. The message transmitted by this transceiver is composed of the consumption value, the serial number of the transceiver and the data relating to the operating status of this transceiver. In response to a request, the message is transmitted to the concentrator 4 according to a two-way communication protocol. The concentrator 4 then sends the message back to the supervisor 3, the latter being able to manage up to 2000 counters by means of 40 concentrators arranged on seven levels. The supervisor 3 has for function the initialization of the network, the management of the transmissions within the network, the collection of data coming from the transceivers 6 and 7, this data being able to be consumption values, serial numbers, alarms , ... Supervisor 3 also has the function of

<Desc / Clms Page number 10>

 automatic network configuration during the initialization phase. Supervisor 3 manages calls from the hubs. The central station 1 notably includes tools for processing the data stored in the supervisor 3 in order to check the state of the network, the battery state of each transceiver, any water leaks or even possible fraud attempts.

 The communication protocol between the various elements of the network allows the transmission of frames comprising the address of the transmitting element and the address of the receiving element. In order to avoid frame collision phenomena, the equipment transmits data only on an order from the supervisor 3. To do this, the communication is bidirectional with confirmation of all requests sent so as to avoid data loss. Conventionally, each frame is terminated by cyclic redundancy check (CRC) bits. The communication protocol according to the invention is remarkable in that it is formatted so as to optimize the energy consumption in each transceiver.

 We will now describe the communication protocol according to the invention with reference to FIGS. 2 and 3.

 FIG. 2 represents a communication protocol according to the prior art. Diagram 15 represents a signal emitted by a transmitter of the prior art and diagram 17 represents the operating state of a receiver of the prior art. The signal 15 is composed of a preamble 12 composed of a binary sequence of successive 0 and 1, followed by a data frame 14. The receiver of the prior art operates according to the

<Desc / Clms Page number 11>

 windowing principle in reception. According to this principle, the diagram 17 comprises a first part 16 in which the receiver is alternately in a sleep state (low state) and in a listening state (high state). The windowing period is made up of a sleep phase and a listening phase. To ensure the occurrence between a phase of listening to the part 16 and the preamble 12 of the signal 15, the duration of the preamble 12 is greater than the windowing period. Therefore, when the occurrence of this product, that is to say that the diagram 17 is in the high state in the presence of the preamble 12, the receiver enters a phase 18. This phase 18 in fact corresponds to a phase d extended listening until the end of the preamble 12. Thus for any receiver of the prior art receiving the signal 15, there is a phase 18 which is more or less large and which corresponds to a non-negligible energy consumption.

It is only upon receipt of the data frame 14 that the receiver of the prior art determines the recipient address contained in the data frame 14. If this recipient address is his, the receiver of the prior art processes all the data contained in the data frame 14. On the other hand, if the recipient address does not concern it, the receiver of the prior art leaves the processing phase 20 and enters the sleep phase.

 The present invention eliminates phases 18 and 20 for a receiver not concerned by the data frame 14 in order to optimize the autonomy of the battery supplying the receiver.

 In FIG. 3, the diagrams 19, 21, 23 and 25 are in accordance with a method according to the invention. Diagram 19 represents a signal emitted for example by the concentrator 4 of FIG. 1. There is a

<Desc / Clms Page number 12>

 new preamble 22 followed by the data frame 14. The preamble 22 is characterized by a periodic insertion of information 32 between alternating series of 0 and 1 for example. The alternating series of 0 and 1 are transmitted at a speed of 2400 baud while information 32 is transmitted at a speed of 9600 baud. This information 32 is a pattern consisting of 16 bits arranged regularly following 8 alternating sequences of 0 and 1. The preamble 22 is therefore composed of the repetition of a block consisting of 16 bits of 0 and 1 alternating transmitted to a 2400 baud rate followed by 16 bits of information transmitted at a rate of 9600 baud. In general, information occupies 20% of the total preamble. Those skilled in the art will readily understand that the characteristics of the information 32 can be determined so that this information 32 occupies a percentage other than 20%.

 By way of example, the concentrator 4 sends a message, represented by diagram 19 in FIG. 3, intended for the transceiver 6 only. But this message also reaches the transceiver 7 placed close to the transceiver 6.

 Diagram 21 corresponds to the operating state of the transceiver 7 according to the invention, this transceiver not being the recipient of the message sent by the concentrator 4.

 Diagrams 23 and 25 correspond to two possible operating states of the transceiver 6 according to the invention, this transceiver being the recipient of the message sent by the concentrator 4.

 In diagrams 21 to 25, when a transceiver device is not in an active mode 20 corresponding to data processing, it is found

<Desc / Clms Page number 13>

 in a standby mode 16 according to the windowing principle: a low state corresponding to a sleep phase and a high state corresponding to a listening phase. During the listening phase, each device checks whether it picks up a series of 0/1 alternating bits. If so, each transceiver device 6 or 7 maintains the listening phase until the information 32 is received.

 Advantageously, each device according to the invention comprises means for analyzing the speed of transmission of the transmitted bits and means for analyzing information 32. This information is for example composed of eight least significant bits of the address of the recipient device, this makes it possible to distinguish 256 different devices. The information also includes four bits of consistency test relating solely to the information and four other bits of various functionalities which will be specified later.

 Thus the listening phase begins with a power level measurement, noise processing and characterization of the data rate received. This characterization consists in analyzing the signal received by detection of two successive edges spaced by a time interval multiple of 104 microseconds for example. This operation quickly offers, after 6.5 ms on average, a strong criterion for a decision to continue the reception phase by analyzing the presence or absence of a signal at 9600 baud, then looking for a pattern 0 / 1. It is therefore possible to relate the duration of the windowing to this duration of treatment and to obtain short cycle times, less than 5 seconds. There are many advantages: - shortening the length of the preamble,

<Desc / Clms Page number 14>

 - reduction in transmission times, - reduction in waiting times before data analysis, - reduction in processing times for exchanges in the network.

 In diagram 21, phase 24 begins with an extended listening phase during which the transceiver 7 analyzes the information 32 received at 9600 bauds. This analysis allows him to verify that he is not the recipient of the message sent by the concentrator 4. As a result, he immediately goes into a sleep phase for for example a duration equal to the duration of transmission of the preamble 22, before returning to a waiting phase 26 for a next message. Unlike the prior art, a device not concerned by the message does not stay awake until the reception of the data frame 14. It can advantageously go into sleep phase during the preamble so as to save its battery.

 On the other hand, in diagram 23, the transceiver 6, from the start of phase 28, knows that the message is intended for it. It can therefore remain awake until the reception of the data frame 14 corresponding to the active data processing mode 20.

 But preferably, the transceiver 6 will operate according to diagram 25 allowing optimization of the energy consumption even for a recipient device. Indeed, after an analysis of the information 32 at the start of phase 30, the transceiver 6 undertakes an optimization strategy by first synchronizing with the preamble 22, then passing into the sleep phase until a few moments before the start of the active mode 20 necessary for processing the data frame 14. With such a method and in

<Desc / Clms Page number 15>

 using a conventional battery with a capacity of 2.2 Ampere-hours, a range of ten years is reached for transceiver devices arranged in an automatic reading network remote from water meters. This process can be applied between the supervisor 3 and the concentrators fitted with batteries.

 Advantageously, each transceiver comprises means for diagnosing the wear of the batteries supplying it. To do this, in each transceiver, the operation is subdivided into several elementary tasks. A weight is assigned to each elementary task, that is to say a value corresponding to a certain amount of energy. Each time we perform a given task, we store the corresponding weight. The accumulation of these weights constitutes an empirical value of energy consumed which is compared with the theoretical capacity of the battery. The transceiver can thus inform the supervisor as soon as the empirical value reaches a certain threshold.

 The four functional bits included in the information 32 can be used to choose between an operation of the diagram type 23, for example when the detection of the preamble took place shortly before the start of the data frame 14, and an operation of the diagram type 25 for detection of the preamble from the start of this preamble.

 The functionality bits can also make it possible: - to carry out measurements of received power level and to initiate a wake-up process which takes this power level into account in developing the response: redundancy of information, non-response if the channel is strongly disturbed ...; to send information

<Desc / Clms Page number 16>

 falling asleep: reception functions are inoperative over a long period, for example twenty-four hours, the equipment being synchronized and idling throughout this period; and - to create a signal which gives priority to the frame and which automatically triggers a data transfer process to the concentrator 4.

 Of course, the invention is not limited to the examples which have just been described and numerous modifications can be made to these examples without departing from the scope of the invention, in particular the state of aging of a ship hull with a view to understanding the risk of rupture by having stress sensors in appropriate areas. The sensors are advantageously associated with transceivers according to the invention. The information from the sensors can then be supplied to the authorities responsible for issuing operating permits for ships and those responsible for monitoring navigation in restricted waters. More specifically, the ship's hull can be equipped, during construction or during its lifetime, with stress sensors. The signals configured and formatted in situ are sent to a device making it possible to establish the cumulative fatigue by compartment, by zone, during use. This continuously enriched information is coded and then stored in an inviolable box, access to which is only possible to the supervisory authorities or their representatives. The communication protocol between the cabinet and the transceivers associated with the stress sensors is done using a process

<Desc / Clms Page number 17>

 according to the invention. Associated with the storage box, a remote interrogation device on VHF support allows the maritime navigation control authorities to receive information on the state of obsolescence of the ship beam during mandatory radio exchanges before entering this ship in a controlled area. Contact with the ship triggers the emission of global summary information on the cumulative fatigue in operation. This information allows the supervisory authorities to estimate the risk that would be taken by allowing the vessel concerned to continue navigation under the conditions of the moment (sea state for example) and possibly trigger a more in-depth interrogation. The information characterizing the cumulative fatigue of the hull would also be accessible to the services accredited when operating licenses are issued by certification companies.

 The present invention can therefore be applied to any wireless communication system for data transfer, requiring high autonomy or low consumption of network equipment, high availability for data transfers, correct radio performance, data from a large number of sensors, and a low cost.
