[0002] In overhead transmission lines, power poles are the main supporting structures. In order to enable operators to easily understand the information of power poles, the main method is to install electronic tags on the power poles. The electronic tags are read by communication equipment to obtain the corresponding information of the power poles.

[0003] However, the current RFID electronic tags can only support information collection at a distance of about 10 meters. This makes it impossible to effectively collect data from power high-voltage towers / iron towers with a height range of 15-55 meters. In order to reduce the height of the electronic tag installation, additional installation devices are required, resulting in an increase in the installation cost of the electronic tag. At the same time, since the electronic tag is installed on the high-voltage iron tower, there is a certain degree of difficulty in the installation process. Therefore, it is necessary to ensure that the electronic tag has a long service life. However, the current electronic tags usually cannot achieve a long service life. Utility Model Content

[0018] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0019] Please refer to Figure 1An electronic tag applied to an electric pole tower comprises a passive radio frequency unit and an energy acquisition unit; the energy acquisition unit is used to acquire external energy to generate electric energy and directly output it; the power supply end of the passive radio frequency unit is connected to the electric energy output end of the energy acquisition unit; the radio frequency end of the passive radio frequency unit is used to receive external radio frequency signals and send radio frequency signals.

[0020] From the above description, it can be seen that the beneficial effects of the utility model are: the electronic tag is composed of a passive RF unit and an energy obtaining unit, and the energy obtaining unit obtains external energy to generate electrical energy and then directly outputs it to the passive RF unit, so that the passive RF unit obtains additional energy input on the basis of the original energy generated by receiving external RF signals, thereby improving the sensitivity of the passive RF unit and increasing the readable distance of the electronic tag; at the same time, compared with the existing method of powering the electronic tag by battery, the life of the electronic tag is affected by the battery and the service life of the electronic tag cannot be increased. The passive RF unit is powered directly by the energy obtaining unit without the need for battery power supply, which can greatly increase the service life of the electronic tag.

[0021] Furthermore, it also includes a voltage stabilizer; the input end of the voltage stabilizer is connected to the output end of the energy harvesting unit; the output end of the voltage stabilizer is connected to the power supply end of the passive radio frequency unit.

[0022] From the above description, it can be seen that by adding a voltage stabilizer between the energy harvesting unit and the passive RF unit, and utilizing the characteristic of the voltage stabilizer that can fix the voltage output, the unstable voltage generated by the energy harvesting unit is converted into a stable voltage and output to the passive RF unit, thereby preventing the passive RF unit from being damaged by sudden high voltage and improving the stability of the electronic tag.

[0023] Furthermore, the voltage stabilizer includes a low voltage stabilizing chip; the output end of the energy acquisition unit is respectively connected to the enable end and the input end of the low voltage stabilizing chip; the output end of the low voltage stabilizing chip is connected to the power supply end of the passive radio frequency unit.

[0024] From the above description, it can be seen that the voltage required by the passive RF unit is usually small. Using a low-voltage stabilizing chip as a voltage stabilizer can provide a corresponding low voltage to the passive RF unit, so that the passive RF unit can work stably.

[0025] Furthermore, it also includes a first capacitor; one end of the first capacitor is respectively connected to the enable end and the input end of the low-voltage stabilization chip and the output end of the energy acquisition unit; the other end of the first capacitor is grounded.

[0026] From the above description, it can be seen that by setting a first capacitor on the transmission line between the energy harvesting unit and the low voltage stabilizing chip, the AC signal generated in the energy harvesting unit is filtered by the first capacitor, so that the low voltage stabilizing chip outputs a more stable voltage signal.

[0027] Furthermore, it also includes a diode; the positive electrode of the diode is connected to the output end of the low-voltage stabilization chip; the negative electrode of the diode is connected to the power supply end of the passive radio frequency unit.

[0028] From the above description, it can be seen that by setting a diode between the low-voltage stabilizing chip and the passive RF unit, the electric energy generated by the low-voltage stabilizing chip can be effectively transmitted to the passive RF unit, while the electric energy generated by the passive RF unit cannot flow back to the low-voltage stabilizing chip, thereby avoiding energy consumption of the passive RF unit and maintaining high sensitivity of the passive RF unit, thereby not affecting the information collection distance of the electronic tag.

[0029] Furthermore, it also includes a second capacitor; one end of the second capacitor is connected to the positive electrode of the diode and the output end of the low-voltage stabilization chip respectively; the other end of the second capacitor is grounded.

[0030] From the above description, it can be seen that a second capacitor is arranged on the transmission line between the low voltage stabilizing chip and the diode, and the AC signal generated by the low voltage stabilizing chip is filtered by the second capacitor, so as to output a more stable low voltage signal.

[0031] Furthermore, the energy acquisition unit includes a solar panel; the output end of the solar panel is connected to the power supply end of the passive radio frequency unit.

[0032] From the above description, it can be seen that by using solar panels as energy acquisition units, when the electronic tag is set on a pole, the electronic tag can convert solar energy into electrical energy through the solar panels to power the passive radio frequency unit, thereby effectively improving the readability distance of the electronic tag in sunny scenes.

[0033] The electronic tag applied to the electric pole tower provided by the utility model can be applied to high-altitude operation scenes such as electric pole towers, so that the operator can collect the information of the electronic tag in the high altitude on the ground. The following is an explanation through a specific implementation method:

[0034] Embodiment 1

[0035] Please refer to Figure 1, an electronic tag applied to an electric pole tower, comprising a passive radio frequency unit 1 and an energy acquisition unit 2; the energy acquisition unit 2 is used to obtain external energy to generate electric energy and directly output it; the power supply end of the passive radio frequency unit 1 is connected to the power output end of the energy acquisition unit 2; the radio frequency end of the passive radio frequency unit 1 is used to receive external radio frequency signals and send radio frequency signals; in order to stably transmit the electric energy converted by the energy acquisition unit 2 to the passive radio frequency unit 1, a voltage stabilizer 3 is arranged between the passive radio frequency unit 1 and the energy acquisition unit 2, and the input end of the voltage stabilizer 3 is connected to the output end of the energy acquisition unit 2; the output end of the voltage stabilizer 3 is connected to the power supply end of the passive radio frequency unit 1; wherein the energy acquisition unit 2 comprises a solar panel J1, and the output end of the solar panel J1 is connected to the power supply end of the passive radio frequency unit 1.

[0036] Please refer to Figure 2 In an optional embodiment, the voltage stabilizer 3 includes a low-voltage stabilizing chip U1; the passive radio frequency unit 1 includes an RFID (Radio Frequency Identification) chip U2; since the voltage output by the solar panel J1 is different under different light intensities, the low-voltage stabilizing chip U1 can output a fixed 1.5V voltage to the RFID chip U2, thereby solving the problem of high voltage output under strong light, thereby not damaging the RFID chip U2; the output end (BAT) of the energy acquisition unit 2 is respectively connected to the enable end (EN) and the input end (IN) of the low-voltage stabilizing chip U1; the output end (OUT) of the low-voltage stabilizing chip U1 is connected to the power supply end (VDD) of the passive radio frequency unit 1; wherein, it also includes a first capacitor C1, a second capacitor C2 and a diode D1; the capacitance of the first capacitor C1 and the capacitance of the second capacitor C2 are both 1 uF; one end of the first capacitor C1 is respectively connected to the enable end (EN) and the input end (IN) of the low-voltage stabilizing chip U1 and the output end (BAT) of the energy obtaining unit 2; the other end of the first capacitor C1 is grounded; the positive electrode of the diode D1 is connected to the output end (OUT) of the low-voltage stabilizing chip U1; the negative electrode of the diode D1 is connected to the power supply end (VDD) of the passive RF unit 1; one end of the second capacitor C2 is respectively connected to the positive electrode of the diode D1 and the output end (OUT) of the low-voltage stabilizing chip U1; the other end of the second capacitor C2 is grounded; a third capacitor C3 is connected in parallel between the first RF end (RF1) and the second RF end (RF2) of the passive RF unit 1.

[0037] The specific working principle of the above electronic tag is as follows:

[0038] After the electronic tag is installed on the power high-voltage tower / iron tower, when the electronic tag is collected during the day: the solar panel J1 receives sunlight and converts solar energy into electrical energy and outputs it to the low-voltage stabilization chip U1, and the output voltage of the solar panel J1 is 0-6.5V; the low-voltage stabilization chip U1 steps down and stabilizes the input 0-6.5V voltage at 1.5V, and supplies energy with a fixed voltage of 1.2V to the RFID chip U2 through the diode D1, thereby enhancing the antenna sensitivity of the electronic tag to -34db, and the readable distance is 50 meters.

[0039] When collecting data from the electronic tag at night, the solar panel J1 cannot provide energy, and the RFID chip U2 is in a passive state. When the operator collects data from the RFID chip U2 through the reader, after the reader transmits radio frequency energy, the RFID chip U2 receives radio frequency energy through the radio frequency end to provide itself with working power. At the same time, the diode D1 can prevent the energy received by the RFID chip U2 from being reversely infused into the solar panel J1, which causes the energy of the RFID chip U2 to decrease, thereby affecting the sensitivity of the antenna. Since the energy received by the RFID chip U2 is extremely weak, its sensitivity can only reach -22db, and the readable distance is 10 meters. That is, the readable distance of a common passive RFID chip is 10 meters, which is difficult to meet the high-altitude reading requirements. In this embodiment, the solar panel J1 provides energy, so that the sensitivity of the RFID chip U2 can be increased by at least 10db, thereby achieving long-distance reading. At the same time, since the collection work is usually carried out during the day, the electronic tag in this embodiment can meet the reading requirements of the electronic tag in most scenarios.

[0040] In summary, the electronic tag applied to the electric pole tower provided by the utility model comprises a passive radio frequency unit, an energy acquisition unit and a voltage stabilizer, and the energy acquisition unit obtains external energy to generate electric energy and then directly outputs the electric energy to the passive radio frequency unit, so that the passive radio frequency unit obtains additional energy input on the basis of the energy originally generated by receiving the external radio frequency signal, thereby improving the sensitivity of the passive radio frequency unit and increasing the readability distance of the electronic tag; and a diode is arranged between the voltage stabilizer and the passive radio frequency unit, so that the electric energy generated by the passive radio frequency unit cannot flow back to the voltage stabilizer, avoiding the energy consumption of the passive radio frequency unit in the passive state, so that the passive radio frequency unit maintains high sensitivity, thereby not affecting the information collection distance of the electronic tag; at the same time, compared with the existing method of powering by battery, the life of the electronic tag is affected by the battery and the service life of the electronic tag cannot be increased, and the passive radio frequency unit is directly powered by the energy acquisition unit without battery power supply, which can greatly increase the service life of the electronic tag and ensure the outdoor service life of the product for at least 10 years.
