The main controller 841 can also interact with the upper computer in a wired or wireless way to perform operation data interaction, including label data and control data.

The working principle and the working method of the fence unit are as follows: when the safe high-voltage fence for livestock works, the solar panel 7 converts solar energy into electric energy, the electric energy is stored in the storage battery BT1 through the solar panel voltage stabilizing circuit 81, the air switch QF is in a closed state, the livestock in each fence is provided with more than one RFID tag 10, and the unique identification number and the corresponding physiological information of the livestock are recorded in the RFID tags 10 worn by each livestock.

When no livestock approaches the fence, the RFID reader/writer 9 does not read the information of the RFID tag 10, at this time, the main controller 841 does not output the PWM signal, the high voltage source 82 is in the non-operating state, the relay switches KM1 and KM2 are in the normally open state, the main controller 841 outputs the high level to the driving circuit of the green light 63, and the light emitting diode D3 emits green light, which indicates that the fence is in the non-energized energy-saving state.

When livestock approaches a fence, the RFID reader 9 reads information of an RFID tag 10, the tag information read by the RFID reader 9 is transmitted to the main controller 841, the main controller 841 outputs a plurality of high-frequency PWM signals to control the controllable high-frequency inverter circuit 822 to work, so that the booster transformer 823 generates high-voltage alternating current, the voltage doubling pulse circuit 824 outputs higher large ripple voltage HV1 after the booster transformer 823 generates high voltage and then performs voltage doubling, the main controller 841 controls the switch of the relay KM1 to be closed through the control circuit of the relay KM1, the voltage of the HV1 output by the high-voltage power supply is connected to the conductive fence line 5 to enter a discharging state, referring to fig. 3, at this time, charges at the opposite tips of the barbs 51 on two adjacent conductive fence lines 5 + and the conductive fence lines-begin to be rapidly accumulated, and when the air breakdown voltage is reached, a discharge arc (spark) is randomly generated between the opposite barbs 51, and crackle sounding discharge sound (the capacitor in the voltage doubling pulse circuit 824 can be discharged continuously after recharging for a certain time after discharge, so pulse discharge is formed), through flash of electric arc and discharge sound, the livestock is expelled to leave the reading area of the RFID reader-writer 9 (namely the area close to the fence), after a period of discharge, if the livestock leaves the reading area of the RFID reader-writer 9, the main controller 841 recovers the previous energy-saving state, and when a period of discharge is performed, if the livestock still approaches the fence (the strength of the signal of the RFID tag 10 read by the RFID reader-writer 9 is judged), the main controller 841 controls the switch of the relay KM1 to be opened, controls the switch of the relay KM2 to be closed, and connects the direct-current high-voltage of the HV2 output by the high-voltage source 82 through the rectifying and filtering circuit 825 to the conductive fence line 5 to enter an electric shock state, and then the livestock is shocked by high-voltage when touching the conductive fence line 5, the shocked livestock tends to quickly escape the reading area of the RFID reader/writer 9, and the main controller 841 resumes the previous power saving state. The light emitting diode D4 emits yellow light when the fence is in the discharging state and the shock state, indicating that the fence is in the power-on operating state. The cooperative switching between the discharge state and the shock state can form an effective shock conditioned reflex for the livestock, and the livestock can leave the area close to the fence after being shocked for a plurality of times and seeing a discharge arc hearing a discharge sound.

When an object (whether livestock or not) contacts and extrudes the conductive fence line 5, when the conductive fence line 5 is stressed and deformed to a certain degree, the microswitch 842 is triggered to act, the main controller 841 receives an action signal of the microswitch and then controls the drive circuit of the red light 61 to output a high level, and the light emitting diode D2 emits red light, which indicates that the fence is in a state of being severely extruded, and the fence system is in a fault state at the moment; when the force on the conductive fence line 5 disappears, the microswitch 842 returns to the previous state, and the main controller 841 controls the red light 61 to be turned off after receiving the action signal of the microswitch.

The specific working principle of the voltage doubling circuit 824 is that when the peak value U of the capacitor C4 in the positive half cycle and the peak value U in the negative half cycle of the input ac voltage are equal, the capacitor C5 is charged by the C4 and the transformer at the same time, the voltage of the capacitor C5 finally reaches 2U, similarly, the charging of the capacitor C6 in the next cycle is 2U, and so on, and the final accumulated output voltage is 10U.

In the working process of the safe high-voltage fence system for livestock, the main controller 841 stores and analyzes the data of the RFID tag read by the RFID reader-writer 9, sets corresponding control logic according to different conditions of each livestock, for example, when the livestock in a multi-time triggered electric shock state is subjected to electric shock, the corresponding electric shock voltage is increased for enhancing conditioned reflex of the electric shock; when the livestock with larger weight is shocked, the corresponding shock voltage is improved; for young livestock, livestock with light weight and livestock in pregnancy, the electric shock voltage in the fence electric shock state is reduced, and the discharge state time is prolonged; suitable shock voltages are set for different breeds of livestock, for example for cattle, sheep or pigs.

The main controller 841 periodically performs operation data interaction including label data and control data to the upper computer in a wired or wireless connection mode.

When the power supply or the conductive fence line 5 is short-circuited, the air switch QF at the output end of the storage battery BT1 is disconnected from a long-closed state, so that the operation safety of the whole fence circuit is ensured, the circuit of the whole fence system is in a power-off state at the moment, the state lamps 6 are completely extinguished, and the air switch QF is closed to electrify the fence after the problem needs to be manually checked and eliminated.
