[0017] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments. Embodiment 1

[0018] like Figure 1 , 2 As shown, an automatic voltage regulation and data reporting voltage regulator includes a collection monitoring module, a core unit, a voltage regulation module, a characteristic signal transmission module, a backup power supply, a Bluetooth module and a 4G module, and the core unit is electrically connected to the collection monitoring module, the voltage regulation module, the characteristic signal transmission module, the backup power supply, the Bluetooth module and the 4G module respectively. The real-time current, the voltage before the voltage regulation, the voltage after the voltage regulation and other data information are read through the collection monitoring module and transmitted to the core unit for the core unit to perform data analysis and processing.

[0019] The core unit is connected to a Bluetooth module. Users can connect the Bluetooth module of the voltage regulator through a mobile device and control the voltage regulator with the APP installed in the mobile device. This allows the user to read the voltage before and after voltage regulation, read historical data, and control the voltage regulator through the APP to perform voltage regulation operations. The voltage regulator can be operated and its data can be read without contact, which enhances operational safety.

[0020] The core unit is connected to a 4G module, which can upload the voltage regulator data to the cloud platform in real time, making it easier for the main station to manage user electricity consumption data. The main station can detect faults in a timely manner based on the voltage regulator data, without the need to install additional equipment, thus reducing costs.

[0021] The voltage regulator has a backup power supply. When a fault occurs and the external power supply is lost, the core unit is powered by the backup power supply, and the voltage regulating module is operated to switch to bypass to ensure power safety, and the data is transmitted to the cloud platform to realize power outage data reporting.

[0022] The characteristic signal transmitting module transmits a specific signal. According to the specific signal waveform, the voltage regulator can be topologically identified and faults located.

[0023] like Figure 2 As shown, the characteristic signal transmitting module includes an optocoupler isolation U1, and the pins 1 and 2 of the optocoupler isolation U1 are connected to the output end of the core unit, the pin 4 of U1 is connected to the collector of the transistor Q2, the pin 3 of U1 is connected to one end of the resistor R1, the other end of R1 is connected to the base of Q2, the emitter of Q2 is grounded, the collector of Q2 is also connected to one end of the resistor R2, the other end of R2 is connected to the positive electrode of the rectifier bridge D1, one end of the resistor Rd is connected between the other end of R2 and the positive electrode of D1, the other end of Rd is connected to the drain of the MOS tube Q1, the gate of Q1 is connected to the emitter of Q2, the source of Q1 is connected to the negative electrode of D1, one end of the resistor R3 is respectively connected to the gate of Q1 and the emitter of Q2, and the other end of R3 is respectively connected to the source of Q1 and the reference ground. Pin 1 of U1 is connected to the high voltage of the core unit, pin 2 is the pin of the core unit, and U1 is controlled by the output end of the core unit.

[0024] D1 is a rectifier bridge, which converts AC power into DC power. R2 is a current limiting resistor, which is a large resistance resistor to protect the subsequent transistor Q2 and the optocoupler isolation U1. Rd is the source resistor of the MOS tube, which controls the current flowing through the MOS tube. Q1 is an N-channel MOS tube, and the injection of the characteristic signal is controlled by the shutdown of Q1. The characteristic signal refers to the DC current flowing through Rd.

[0025] Q2 is a transistor, the on-off of the transistor can control the on-off of Q1.

[0026] R1 is the base resistance of transistor Q2, which controls the current flowing to transistor Q2 and protects transistor Q2.

[0027] U1 is an optocoupler isolation, one side of the optocoupler is connected to the core unit, and the other side controls the transistor Q2, and the shutdown of the transistor Q2 is controlled by the signal on the core unit side.

[0028] The core unit controls the on and off of transistor Q2 by controlling pin 2 of optocoupler isolation U1. When pin 2 of optocoupler isolation U1 is at a low level, pin 3 of optocoupler isolation U1 is at a high level, so the base of transistor Q2 is at a high level, and transistor Q2 is turned on. At this time, the emitter level of transistor Q2 is at a low level (grounded, so it is always at a low level), so the gate of Q1 is at a low level, Q1 is turned on, and the current on the right side of rectifier bridge D1 is as follows: the current flows from the positive pole of rectifier bridge D1 through resistor Rd, from the drain of Q1 to the gate, and finally returns to the negative pole of rectifier bridge D1. At this time, the power consumption is mainly in Rd and Q1. By selecting the resistance value of Rd, the current injected between L / N can be stably controlled to ensure that the current is constant and there is no interference current. In addition, this solution uses fewer components and has a low price cost. It does not require the installation of other equipment, thereby realizing a low-cost fault location function. Embodiment 2

[0029] Embodiment 2 is based on Embodiment 1, and further optimizes the core unit, Bluetooth module, 4G module and voltage regulation module.

[0030] The core unit uses the domestic single-chip microcomputer APM32F103VET6 as the main control chip. The APM32F103VET6 chip realizes the above control function and has a low cost.

[0031] The Bluetooth module uses the domestically produced CST92F42 Bluetooth chip.

[0032] The 4G module is designed using the EC05-DNC chip.

[0033] The voltage regulating module uses a single-phase control transformer module BK-220V.
