Definitions
- the subject of the present invention is a method of managing the operation of a remote information sensor intended to be used with a meter, for example, but not only, a counter of the electric meter type.
- the present invention also relates to a device, such as a teleinformation sensor, capable of implementing the method according to the invention.
- the purpose of the invention is essentially to propose a remote information sensor, and a management of the use of said sensor, which makes it possible to extend the autonomous lifetime, that is to say without replacing the battery, the sensor considered .
- teleinformation means any information that is available in the counter in question.
- the field of the invention is, in general, that of meters for measuring the consumption of an element such as water, gas, heat or electricity.
- the present invention will be more particularly described in the case where the counter involved is a counter of the electric meter type, but the object of the invention is applicable to any other type of meter - in particular the gas, water and / or gas meters. or heat especially in the case where they deliver a modulated signal.

- This data can in particular be consumption consumption values of the physical quantity with which the counter is associated, and / or information relating to the identification of the counter, and / or information relating to the correct operation of the counter, and / or more information on the security of the meter, or any other type of information.
- the counter meter information was taken manually by a specialized agent, or by a user who was to return the information to the appropriate management company. Automation of the readings thus proved judicious, and it was thus proposed the use of electronic modules acting as remote information sensors.
- a sensor constitutes a data acquisition unit; it is intended to be connected to a meter considered, and it is particularly capable of extracting information from said counter, to store them, and advantageously to transmit remotely, automatically or following a solicitation, for example by means of a radio module that includes.
- the senor Once installed and connected to the meter for which it is intended, the sensor is intended to remain in position for a very long time. Typically, the intended duration before its replacement is of the order of fifteen years.
- the sensor considered incorporates a battery, usually in the form of a 3.6-volt battery. It is therefore necessary to optimize the consumption of the energy resource that constitutes the battery; nowadays, the sensor battery is solicited right out of the production plant of said sensor. Indeed, right out of the factory, some electronic modules of the sensor are powered by the battery, including a demodulation module information collected from the meter. And very often, between the output of the production plant, and the effective commissioning of the sensor considered, several years pass. Thus, during these years, the sensor consumes its energy resource unnecessarily, which limits its lifetime once it is put into service by being connected to the meter for which it is intended.
- the method and the sensor according to the invention propose a solution to the problem just described.
- the invention provides the definition of a particular standby mode, said deep standby mode, in which is placed the sensor considered as soon as it leaves the production plant.
- the deep sleep mode is maintained until the sensor is connected to a meter, and the meter transmits an appropriate signal to the sensor, called the deep sleep output signal.
- the sensor may, after having been connected to a counter, be placed again in the deep sleep mode.
- the invention therefore essentially relates to a method for managing the operation of an information sensor for a meter, in particular of the electric meter type, characterized in that it comprises the various steps consisting of:
- the method according to the invention may comprise, in addition to the main characteristics which have just been mentioned in the preceding paragraph, one or more additional characteristics among the following:
- the step of taking the sensor out of the deep sleep mode comprises the various operations of:
- the method comprises the additional step of, in the absence of a control signal, to switch the sensor from the active mode to the deep sleep mode.
- the method comprises the additional step of, prior to the step of switching the sensor from the active mode to the deep sleep mode, storing information transmitted by the counter to the sensor in a memory module.
- the sensor according to the invention may comprise, in addition to the main characteristics which have just been mentioned in the preceding paragraph, one or more additional characteristics among the following:
- the detection module comprises a peak detector circuit.
- the peak detector circuit is of the tripler voltage circuit type.
- the detection module comprises an input resistance value of between 1 kilo-ohm and 10 kilo-ohms, in particular 4.7 kilo-ohms.
- the detection module comprises means for generating an asynchronous interrupt signal when a remote information signal is received by said sensor.
- the switch device comprises a MOSFET type transistor which is passing during the transmission of a control signal, emitted by the microcontroller, on the gate of said transistor.
- FIG. 2 a flowchart illustrating an exemplary implementation of the method according to the invention
- FIG. 3 an example of an electronic circuit that can be used in the sensor according to the invention for detecting a signal able to make said sensor come out of a deep sleep mode;
- FIG. 1 there is shown an example of remote information sensor 10.
- the teleinformations also designated as information, come from a counter 1, in particular an electric sensor.
- the sensor 10 comprises the following elements:
- the demodulation module 2 is connected to the microcontroller 7 via a link 18;
- the link 18 is connected to a UART port (Universal Asynchronous Receiver Transmitter - it is an asynchronous transceiver) of the microcontroller 7;
- the function of the demodulator 2 is to demodulate the information transmitted by the counter to transform them into signals compatible with the microcontroller 7;
- switch device 6 connected by a first link 13 to the demodulation module 2; moreover, the switch device is connected to the microcontroller 7 by a link 14;
- a battery 5 for example a battery of 3.6 volts; the battery 5 is connected on the one hand to a VCC port of the microcontroller 7 by a link 15, and on the other hand to the switch device 6 by a link 16;
- a temperature sensor 4 connected to an input port I / O of the microcontroller 7 via a link 16;
- the counter 1 is connected to the remote information sensor 10 by a first link 19 connected to the detection module 3 and by a second link 20 connected to the demodulation module 2.
- a first link 19 connected to the detection module 3 and by a second link 20 connected to the demodulation module 2.
- a first step 21 is to place, for example from the output of the production plant, the sensor 10 in a particular mode, said deep sleep mode.
- the deep sleep state is a state in which the battery 5 does not supply the various elements of the sensor 10 which have just been described.
- the clock of the microcontroller 7 is not activated, and the demodulation module 2 does not consume energy.
- a second step 22 consists of installing a sensor 10 in a user.
- the installation involves the connection of the sensor 10 to the counter 1 via the link 19 and the link 20.
- a next step 23 is a step detection by the sensor 10, and more precisely by the detection module 3, a teleinformation signal transmitted by the counter 1.
- the detection module 3 transmits on the link 17, a signal asynchronous interruption received at the IT port of the microcontroller 7.
- the detection device 3 is advantageously an energy detector; it can for example use the energy of the signal received from the counter to become active and generate the interrupt signal; any other type of energy detector can be used in the sensor according to the invention.
- the microcontroller 7 As soon as the microcontroller 7 receives the asynchronous interrupt signal, the microcontroller 7 is activated in a next step 24 by activating the internal clock of the microcontroller 7. A control signal Sc is then emitted by the microcontroller 7 via the link 14 to switch the switch device 6, and make it pass so that the power of the various modules, including the demodulation module 2, is effective. Exchanges between the demodulation module 2 and the UART port of the microcontroller 7 can then be performed.
- a next step 25 is provided in which the sensor 10 returns to the deep standby mode.
- the data received by the sensor 10 are stored in the memory module 9.
- Such a step is advantageous and in no way interferes with the exploitation of the information received from the counter 1, said information being transmitted punctually, and not continuously.
- the transition to the deep standby mode is carried out by remission of a new control signal from the microcontroller 7 to the switch device 6, or by the interruption of the control signal Sc, rendering the transistor considered non-conducting.
- FIG. 3 illustrates an exemplary embodiment of the detection module 3.
- Figure 3 is described in conjunction with Figure 4 which shows different signals observed in the detection module.
- FIG. 3 shows an electronic circuit 301 that respects in particular the following constraints:
- a dynamic range from 800 mV to 5 V peak (differential voltage between two son constituting the link 19 of a signal Sin information Sin, so any input signal greater than 800 mV must imperatively cause the output of deep sleep mode, by being interpreted as information coming from the counter 1 and ultimately causes the battery 5 to be put into service by closing the switch device 6, conversely, an input signal of less than 300 mV must not cause an output Deep standby mode:
- the circuit 301 does not generate nonlinearity seen from the input of the sensor 10, not causing an input impedance discontinuity regardless of the operating conditions of said circuit 301.
- the signal Sin information is transmitted by the counter 1. It is also received by the demodulation module 2.
- the signal Sin information enters the detection module 3 through the crossing of a resistance input R1, high value, by example 4.7 KOhms, which minimizes the nonlinear effects caused by the conduction of diodes present in the circuit 301, so that from the point of view of the input of the demodulation module 3, the impedance remains linear which whatever the conditions. As can be seen in FIG.
- the teleinformation signal Sin is a sinusoidal signal having a peak-to-peak amplitude of the order of 800 mV; according to the standard in force, the teleinformation signals emitted by the counter 1 are 8-bit signals, each bit corresponding to a signal Sin of the type represented, that is to say a modulated signal ASK of frequency equal to 50 Hz, and of duration 833 micro seconds.
- the signal actually received by the detection module 2 is a slightly attenuated signal, due to the transmission in parallel to the demodulation module 3 of the signal Sin.
- the peak detector circuit is of the voltage tripler type.
- the voltage tripler has the following structure:
- the signal flowing in the detection module 3 successively meets: arranged in parallel, on the one hand a first capacitance C1, for example of value 1, 2 nF (nanofarad) and, on the other hand, a first diode D1 and a second diode D2; a second capacitor C2, for example of value 1, 2 nF, is disposed between the ground of the circuit 301 and a connection point P1 disposed between the first diode D1 and the second diode D2;
- a third capacitor C3 for example of value 1 nF.
- the orientation of the three diodes is such that during a first positive half-wave of the signal Se at the input of the voltage tripler, the diode D1 is blocked and the first capacitor C1 is charged at the value Vc, which corresponds to the peak voltage Se signal; during the first negative half-cycle of the input signal, the diode D1 is conducting, and the second capacitor C2 is charged at the value 2Vc; during the second positive half-cycle of the input signal, the diodes D2 and D3 are on, and the third capacitor C3 is charged to the value 3Vc.
- a continuous output signal Ss represented in FIG. 4 which tends to a value substantially equal to three times the input voltage Se of said voltage tripler 302.
- a second resistor R2 for example, a value of 1000 kilo-ohms, is arranged in parallel at the output of the voltage tripler 302; this resistor is used for the discharge of the capacitor C3 when the signal Sin is no longer supplied at the input of the detection circuit 3.
- a third resistor R3 for example 47 kiloohms value, whose function is to reduce the value of the intensity of the flowing current, and arriving on the basis of a bipolar transistor Q1.
- a third resistor R3 for example 47 kiloohms value, whose function is to reduce the value of the intensity of the flowing current, and arriving on the basis of a bipolar transistor Q1.
- the intensity of the output signal of the voltage tripler 302 is sufficient, which occurs at a time t1 in the example under consideration, ie for a peak-to-peak voltage of about 1 volt per second. Ss, the transistor Q1 becomes on and an output voltage Sout of the circuit 301, measured at the collector of the transistor Q1, decreases.
- the collector is also connected to the IT port of the microcontroller 7, while the transmitter is connected to the ground of the circuit 301.
- the transmission to the detection circuit 3 of the Sin information signal is thus reflected by the detection at the IT port.
- an asynchronous interrupt signal resulting in the transition from a high signal to a low signal.
- the microcontroller 7 then goes into an active mode, puts its clock into activity, and produces the control signal Sc which is received by the switch device 6.
- the proposed implementation for the circuit 301 is based on an envelope detection of the voltage tripler-based information signal Sin enabling the detection of sufficient energy taking into account the dynamics of the input signal and under small signal conditions. to cause the conduction of a bipolar transistor.
- the proposed implementation makes it possible to obtain a reaction time of less than 800 microseconds, regardless of the usual ambient temperature conditions observed.
- the signal Sc is transmitted on the gate of a P-type MOSFET transistor Q2, the source of which is connected to the battery 5 and whose drain is connected to the demodulation module 2.
- the transistor can go from a blocked state to a on state, then allowing the power supply of the demodulation module 2; conversely, the disappearance of the signal Sc blocks the transistor Q2, and plunges the sensor into the deep sleep mode.
