Definitions

  • the invention relates to a device for transmitting data from an animal body with a passive transmitter that can be inserted into the animal body and that has a transmitter resonant circuit consisting of a transmitter coil and at least one transmitter capacitor, and with a receiver that has an excitation coil and a receiving coil that has a
  • the capacitor forms a receiver resonant circuit, a modulation capacitor changing its frequency being connectable in the transmitter resonant circuit.
  • Such a device is known for the electronic identification of animals, in particular racing horses.
  • the transmitter which is made as small as possible, is implanted in the neck muscles of the horse.
  • the transmitter resonant circuit When the transmitter resonant circuit is excited by the excitation coil of the receiver, it delivers a signal controlled by a memory matrix, by means of which the horse can be identified.
  • This device thus only delivers an identification signal, but no other data.
  • European patent application EP 87 103 573.9 To monitor the state of health or the performance of a herd of cattle, it is desirable to monitor the desired physical or chemical parameters from the body of each individual animal in the simplest possible way. A particularly meaningful measurement is the body temperature, because an increase in temperature provides a very early indication of the onset of an illness in the animal.
  • This animal can therefore be separated from the herd before the onset of the disease, so that the risk of infection can be excluded or at least considerably reduced.
  • the object of the invention is therefore to design a device of the type mentioned at the outset in such a way that the desired physical or chemical parameters on the carcasses of a larger herd of cattle can be monitored in a simple manner with little effort.
  • the transmitter resonant circuit is impressed with a coded signal which is supplied by a sensor which detects a physical or chemical measured variable on the animal body.
  • the transmitter can be used in different ways in the animal body. For example, it can be implanted subcutaneously or placed in the animal's digestive tract. Because the passive transmitter is not a suitable energy source has, but draws its energy from the excitation coil in the receiver, the transmitter can remain in the animal body for any length of time.
  • the receiver can be arranged at a point where the animals must inevitably move past a short distance, for example at a passage through which the herd of cattle is regularly driven.
  • an analog signal supplied by the sensor can be converted in an analog-to-digital converter into a digitally coded electrical signal or a frequency and used to modulate the transmitter resonant circuit.
  • a sensor suitable for this can be used in adaptation to the physical or chemical measured variable to be recorded in each case.
  • the measured variable to be recorded is the body temperature of the animal, it can be provided according to a preferred embodiment of the invention that at least one of the capacitors in the transmitter resonant circuit contains a dielectric with a temperature-dependent dielectric constant and is used as a temperature sensor.
  • This embodiment is particularly preferred because of the very simple construction, because no separate temperature sensor is used, the signal of which would have to be encoded in a coding device. Since the capacitor, which is already present in the transmitter resonant circuit, is also used as a temperature sensor, it is influenced by that which occurs when the temperature fluctuates Capacity change immediately the frequency of the transmitter resonant circuit. This change in frequency is recorded in the receiver oscillation circuit and immediately shows a change in temperature in the animal body. The animal in question can be immediately separated from the herd and examined or quarantined.
  • the transmitter capacitor preferably forms the temperature sensor, while the modulation capacitor which can be activated by the memory matrix supplies an identification code for each individual animal.
  • a particularly high temperature sensitivity of the capacitor used as a temperature sensor is achieved according to the invention in that barium titanate is used as the dielectric.
  • the transmitter coil contains a ferrite core and is enclosed together with the transmitter by a liquid-tight shell which forms a " buoyancy body at one end of the ferrite core.
  • the invention is based on one
  • Fig. 1 can be introduced into an animal body transmitter for transmitting the body temperature and Fig. 2 is a highly simplified circuit diagram of this transmitter and the associated receiver.
  • the transmitter -1 shown in Fig. 1 in a simplified section is intended to be used in the digestive tract of a cattle.
  • the transmitter includes a transmitter coil 2, the ferrite core 3: surrounds. At the upper end of the ferrite core 3, an integrated circuit 4 and a transmitter capacitor 5 are attached.
  • a liquid-tight shell 6 surrounds the transmitter and forms at its upper end a cavity 7 as a buoyancy body, which ensures that the transmitter remains upright floating in the cattle's stomach, which contains liquid.
  • a memory matrix 8, a control device 9 and a modulation capacitor 11 which can be activated by a switch 10 form the integrated circuit 4.
  • the transmitter coil 2, the transmitter capacitor 5 and the modulation capacitor 11 are connected in parallel and form a transmitter resonant circuit 12, the natural frequency of which depends on the capacitance of the capacitors 5 and 11 depends.
  • an excitation coil 14 is arranged, which is acted upon by a coil driver 15 with a predetermined fixed frequency.
  • a receiving coil 16 forms one with a capacitor 17
  • the receiver resonant circuit 18 is connected via a comparator 20 to a counter 21, which supplies an output signal to an output line 22.
  • Positive and negative voltage pulses are alternately connected to the excitation coil 14.
  • the three coils 2, 14 and 16 are magnetically coupled.
  • the resonant circuit formed by the transmitter coil 2 and the transmitter capacitor 5 is excited by short current pulses in the excitation coil 14.
  • the modulation capacitor 11 is switched on by the integrated circuit 4, the frequency of the transmitter resonant circuit 12 is reduced.
  • the switching on of the modulation capacitor 11 is controlled as a function of the values stored in the memory matrix 8.
  • the modulation capacitor 11 is a capacitor integrated on the chip. Strictly speaking, it is only the normally undesirable gate-source capacitance of a large-area field-effect transistor.
  • the transmitter capacitor 5, however, is soldered as a component and can therefore be exchanged.
  • the receiver resonant circuit formed by the receiving coil 16 and the capacitor 17 oscillates at the same frequency as this due to the magnetic coupling with the transmitter coil 2.
  • the resonance frequencies of the individual resonant circuits are dependent on one another due to the magnetic coupling of the coils.
  • the resonance frequency of the transmitter resonant circuit 12 (FIG. 2) is determined not only by the capacitances of the capacitors 5 and 11 and the inductance of the coil 2, but also by the inductances of the coils 14 and 16.
  • the task of the excitation coil is to do the whole To stimulate the resonant circuit system, but not to impose a frequency on it. Therefore the circuit is designed so that only short current pulses flow through the excitation coil 14.
  • the comparator 20 detects the zero crossings of the signal, which are counted in the downstream counter 21.
  • the counter 21 When the counter 21 has counted a fixed number of zero crossings, it causes the coil driver 15 to emit a new excitation pulse.
  • the time it takes counter 21 to count a fixed number of zero crossings is a measure of the frequency at which the whole system vibrates.
  • the data stored in the memory matrix 8 with a capacity of 64 bits are encoded according to the Manchester code.
  • a data cycle is always the same length. It consists of either a short and a long data phase to transmit a "1", or a long and a short data phase to transmit a "0".
  • the resistor 1 serves to reduce the sensitivity of the receiver resonant circuit 18. This is necessary because, depending on the state of the switch 10, two different frequencies have to be transmitted / ground.
  • the data transmission takes place in that two different frequencies are transmitted. In order to detect the data, these two frequencies must be measured. This is done by the counter 21, which counts a fixed number of zero crossings of the received signal. The time it takes the counter 21 to count a fixed number of zero crossings is a measure of the frequency. The subsequent circuit, which evaluates the data signal at output 22, measures these times. The data are obtained by comparing these times, because this corresponds to a frequency comparison. In order to measure the temperature now, it is not the time differences but the absolute time values that must be measured and displayed. A missing negative excitation pulse is interpreted by transmitter 1 as a reset signal and starts the data transmission again. This allows the system to be brought into a defined initial state.
  • the transmitter capacitor 5 in the passive transmitter 1 contains barium titanate as the dielectric, so that the transmitter capacitor is temperature-dependent.
  • the dielectric constant of barium titanate is temperature dependent due to the physical effect of the Curie temperature. Since the entire transmitter 1 and thus also the transmitter capacitor 5 assume the body temperature of the cattle, in whose body the transmitter 1 is located, the frequency of the transmitter resonant circuit 12 changes depending on the body temperature. The frequency ascertained in the receiver oscillating circuit 18 and transmitted by the transmitter coil 2 thus represents a measure of the body temperature.

Abstract

Un émetteur (1) pour transmettre des données, notamment la température, émanant d'un corps d'animal, peut être implanté dans ce dernier. Une bobine excitatrice (14) dans un émetteur (13) excite un circuit oscillant (12) qui, outre la bobine d'émetteur (2), possède au moins un condensateur (5). Ce dernier renferme comme diélectrique du titanate de barium et est donc variable sous l'influence de la température. Ledit condensateur (5) constitue un détecteur de température influant sur la fréquence du circuit oscillant (12). Cette fréquence est enregistrée et évaluée par un circuit oscillant (18) logé dans le récepteur (13).
