Definitions

  • This invention relates to improvements to energisers.
  • the electric fence industry is highly competitive. In this competitive market, the perception is the more powerful the energiser, the better the energiser. An energiser that has a greater shock effect, while still adhering to the regulations placed on the various electrical parameters associated with electric fences, are the most desirable. Consequently, more powerful energisers are being produced.
  • Such environmental conditions include the earthing of the electric fence system by the conductive wires coming in contact with grass and weeds. Therefore a consumer must control the height of the weeds and grass surrounding an electric fence or along its length. This involves increased costs due to labour, sprays and so forth.
  • the degradation of the conductive wire itself has a greater negative effect on the effectiveness of an electric fence system that has a lower power energiser as opposed to a high power energiser.
  • a powerful energiser may still deliver an effective shock along the conductive length despite conductive degradation.
  • Electric fences are usually set up to enclose animals or prevent them from leaving or entering a particular area. Such animals include cows, bulls, sheep, deer and other animals. In the case of bulls, powerful energisers are required to give a sufficient shock given the size of the animal.
  • a high voltage pulse is preferable for physiological reasons as a high voltage pulse can deliver a shock of greater multitude through the body of an animal more effectively than a low voltage pulse.
  • Conductive material may also fall on the fence and create a conditional current drain on the energiser causing it to become overloaded. This can result in energiser damage, or result in a reduction in the effectiveness of the fence system.
  • an electric fence energiser including
  • control unit that can control the output of the energiser, wherein the output of the energiser is a series of pulses
  • a sensing means that can relay information to the control circuit regarding the detected electrical load on the output of the electrical fence energiser
  • the energiser output is controlled by the control unit according to the rate of change of the electrical load detected by the sensing means.
  • the energy storage device fitted in most energisers is a capacitor, or a set of capacitors.
  • the output of most energisers is supplied by the discharging of one or more energy storage capacitors.
  • the charge and hence the voltage on the storage capacitor may be controlled by a number of means.
  • a control unit containing a controllable charging circuit may be placed somewhere between the charging circuit of the energiser and the capacitor. Furthermore, the controllable charging circuit may be switched on and off to control the charge reaching the capacitor as is desired.
  • this controllable charging circuit may be a triac.
  • a microprocessor or micro-controller technology may be used in the control circuit.
  • controllable charging circuit may be connected to one of the ports on the microprocessor.
  • the microprocessor may then calculate a value, in accordance with the predetermined parameters, or access and value from a memory means.
  • This value may be indicative of the voltage which should be stored on the energy storage capacitor that gives the desired output voltage on the fence line once the capacitor is discharged through the energiser transformer.
  • the microprocessor may then open or close the controllable charging circuit as appropriate to allow the energy storage capacitor to be charged to another appropriate value based on the load on the output of the transformer.
  • the rate of change may involve sensing a number of values of load on the output of the energiser over a period of time using the sensing means. These values may be stored in the memory means of the microprocessor.
  • the sensing means which provides an indication of the load, may be achieved in a variety of ways.
  • current feedback may be used.
  • a resistor of known value can be placed on the secondary side of the energiser output transformer. The voltage across this resistor can be measured, from which the current can be calculated and used to estimate the energiser load.
  • a resistor of known value may be placed on the primary side of the energiser circuit and the voltage measured across the resistor. The current can then be calculated and the effective impedance on the secondary side of the energiser can be calculated.
  • voltage feedback may be used.
  • the energiser load may be estimated from the peak voltage at the secondary side of the transformer. For example the peak voltage on the secondary side can be measured while maintaining the isolation between the transformer primary and secondary through a capacitor divider network or a tertiary winding on the output transformer.
  • a system of measuring the phase angle between the voltage and current waveforms may be used.
  • a method of measuring primary voltage overswing to deduce output load may be used.
  • the change in load, and the duration of the measurement period of the change in load, before the control circuit determines the necessity for a change to the charge stored on the output capacitor is necessary will be adjustable by the user.
  • the controller of the site may elect a low threshold in order to insure they are alerted to any alarm, although this may raise the likelihood of them receiving false alarms, whereas sites where low value stock are situated, the site controller may elect a higher threshold in order to reduce the number of potential false alarms.
  • the output voltage from the energiser typically drops in the region of 5-10% when a load is applied to the energiser output
  • the drop was also almost independent of the distance from the energiser that the load was applied within the tested range of 0-5 Km.
  • a good reference period for the output voltage was found to be a rolling average over the last 5-30 minutes.
  • a minimum of three pulses, below the threshold set to detect an alarm condition, in preferred embodiments will be used in order to allow for animals to make contact and then clear the fence in its normal operation.
  • the change in output may be made by way of reducing the charge on the capacitor or even stopping the pulses or reducing the frequency of the pulses.
  • the predetermined parameters may be such that this may correspond to a degradation of the electric fence line, or wet grass growing against a fence, and so forth.
  • the output on the energiser may then be increased according to the level of degradation, which may be determined by the predetermined parameters.
  • the intensity of the output may be increased to compensate for the degradation in the electric fence line.
  • the present invention may be a stand-alone device that works in combination with existing energiser systems.
  • the present invention may be incorporated into new energisers.
  • a bull may fall on the fence after fighting and this may be detected by the present invention because the load changes by greater than 5%. for more than three consecutive pulses.
  • the farmer may be alerted to this via communication systems. The farmer may then see to the problem.
  • a degradation over a long period of time may be detected by the sensing means, and via the predetermined parameters be identified as signal degradation due to wet grass or a line fault.
  • the farmer may alerted to this via communications means and then may go and remedy the problem.
  • Figure 1 shows a schematic diagram of the present invention
  • Figure 2 shows a schematic diagram of the present invention fitted to an existing energiser system.

  • the microprocessor incorporated in the control circuit 3 adjusts the controllable charging circuit such that the energy storage capacitor is charged to a level in accordance with the predetermined parameters, in relation to the load on the electric fence line 6 and consequently the output 5 of the electric fence energiser.
  • the sensing means may sense a slow gradual change in the load on the output which, in accordance with the predetermined parameters, may cause the energy storage capacitor to be charged to a different level.
  • a rapid change in the load over consecutive pulses may indicate a different event, and may result in the energy storage capacitor being charged by the controllable charging circuit to a different level in accordance with the predetermined parameters.
