There is preferably integrated antenna 15 to be used to run thus and/or the wireless radio transmission of consumption data.One according to the invention
Special embodiment, the radio chip for communication are also desirably integrated into microprocessor 6.
Energy supply device 7 is including accumulator (such as dry cell or battery) and has at least one electric parameter,
The value of the electric parameter substantially proportionally changes with preceding supply.According to a preferred implementation modification, as electrical
Parameter uses the voltage or residual voltage of energy supply device 7, declines with the consumption of investment, such as passing through micro process
Decline during 6 decoding data packet of device.Clearly, within the scope of the invention however also other electricity including energy supply device 7
Gas parameter, for example, charge, current strength, resistance, power, function, capacitor, frequency, cycle duration, inductance, current density or
It is such.
Microprocessor 6 before transmitting decodes data by data encoding and/or after receipt.As shown in fig. 3a,
Coding or decode carries out in so-called coding stage KP stagely at this, and wherein the value of electric parameter that is, voltage are from initial
Value AW variation for example declines.The Restoration stage at least partly restoring electric parameter is equipped between each coding stage KP.
In line with the purpose, the duration of Restoration stage so determines size, so that electric parameter is during Restoration stage towards initial
Value AW changes or reaches again the initial value.Coding or decoding are not thus entire areas but gradually (peu à peu) is implemented, so as to
It protects energy supply device 7 and does not allow too low voltage, that is, restore interruption (Restoration stage) and be inserted in corresponding decoding step
Suddenly between (coding stage).Such as thus prevent: the passivation layer of battery is broken (brechen) too strongly, thus coding and it is extensive
Multiple stages period is alternately arranged.In this way, Restoration stage can determine size, so that needing significantly beyond script so longly
Recovery time, such as in fig. 3 a shown in, so as in uncertain power supply (Strombezug) for example due to occurring suddenly
Data send and also have enough recovery times available.
A preferred embodiment according to the invention, the threshold value SW of electric parameter is provided according to electric parameter, wherein electricity

Cunningization.For turn on and off decoded switching mechanism in this as functional group be located in microprocessor 6 or, microprocessor
6 construct preferably as SMD module and are allocated to control and analytical unit 9.
The duration t that decoding stage can be limited in line with the purpose is not up to threshold by inference in the duration
Value SW.Voltage interruption Δ V is calculated according to the product of current strength I and duration t divided by the capacitor C of capacitor 18 herein.Example
If decoded duration t can be 20ms, so that microprocessor 6 is with the current strength of such as 4mA of needs and 1000 μ F
Capacitor causes the voltage interruption of 0.08V:
U (Δ electric discharge)=It/C=4mA20ms/1000 μ F=0.08V.
In addition, the voltage drop U (after electric discharge) and the voltage during charging that generate when electric current absorbs rise U (charging
For example the battery of the cell voltage (U (bat)) with 3.3V can be determined afterwards) as follows:
U (after electric discharge)=U (Bat)-U (Δ electric discharge)=3,3-0,08=3,22V
U (after charging)=U (after electric discharge)+U (after Δ electric discharge) (1-e^ (- t/ τ)).
Also for example recovery time t can be exported by threshold value SW, wherein capacitor 18 can in order to restore the recovery time t of needs
To be calculated according to timeconstantτ.Capacitor 18 is by the voltage U (Bat) of battery 17 via the electricity being connected in series with capacitor 18
The recovery of resistance 19 or charging exponential form carry out.The timeconstantτ of the series circuit of capacitor 18 and resistance 19 is resistance R and capacitor
The product of device C.
τ=RC
For example, thus in cell voltage U (Bat)=3.3V, 2000 ohm of resistance and capacitor=1000 μ F capacitor
The recovery time t for calculating 9.2 seconds in the case where device 18, wherein decoding must be turned off, to charge to capacitor 18:
U (after electric discharge)=0.99U (bat)
U (Δ charging)=U (after charging)-U (after electric discharge)
U (Δ charging)=U (Δ electric discharge) (1-e^ (- t/ τ))
U (Δ charging)/U (Δ electric discharge)=(1-e^ (- t/ τ))
E^ (- t/ τ)=1-U (Δ charging)/U (Δ electric discharge)
T=- τ ln (1-U (Δ charging)/U (Δ electric discharge))
1000 μ of τ=RC=2000 ohm F=2 seconds
T=-2ln (1- (0.990.08V)/(the 0.08V)) second
T=9.2 seconds.
