Description

Technical Field

[0001] This invention relates to the field of electronic transformers, and in particular, to a high-frequency self-oscillating electronic transformer. Background Technology

[0002] A high-frequency electronic transformer is simply an electronic transformer with a high operating frequency, generally above 20kHz. There's a common way to classify the operating frequencies of electronic transformers as high, medium, and low: 50Hz or 60Hz is called power frequency, or below that is called low frequency; 60Hz to 20kHz is called medium frequency (400Hz is medium frequency, not power frequency); and above 20kHz is called high frequency. Why is 20kHz chosen as the boundary? Because 20kHz is the upper limit of sound frequency; beyond that, audible noise becomes inaudible. Therefore, operating frequencies above 20kHz, from 20kHz to the MHz or GHz range, are considered high frequency. High frequency can be further divided into higher frequency (20kHz–50kHz), mid-high frequency (50kHz–200kHz), high frequency (200kHz–1MHz), and ultra-high frequency (above 1MHz), but all belong to high frequency. The understanding of high frequency doesn't differ based on the applicable power. The notion that high frequency has different ranges at different power levels is a misunderstanding.

[0003] A high-frequency self-oscillating electronic transformer refers to an electronic transformer (ET) whose basic schematic diagram includes a conventional full-bridge rectifier, a self-excited oscillation chopper circuit, and an output power transformer. Compared to the line voltage, the self-excited oscillation circuit operates at a relatively high frequency, typically between 20 and 300 kHz. This allows for the use of smaller magnetic components at the transformer's output stage, thus reducing the overall cost of the electronic transformer compared to a magnetic transformer.

[0004] In the existing structural design, the basic schematic diagram shows that the input terminal passes through a full-bridge rectifier, then a self-excited oscillation chopper circuit, and finally an output power transformer. We know that multiple sensors are installed inside this product to collect and monitor the operating status or condition of various modules. For example, when detecting the operating temperature of a voltage regulator, a temperature sensor needs to be installed within the mounting housing to detect the temperature inside and transmit the data to a processor for processing or storage. However, if this sensor is powered by an electronic transformer, its load will increase. To avoid using the circuit module for power, an external battery is required. This results in high power consumption for collecting various data, necessitating frequent battery replacements and causing inconvenience. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art and at least partially solve the technical problems in the related art by providing a high-frequency self-oscillating electronic transformer that can improve the configuration of temperature monitoring data and power supply control.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a high-frequency self-oscillating electronic transformer, including a base, a shell, a self-excited oscillation circuit and a transformer circuit module vertically fixed on the base, and a temperature sensor for collecting the ambient temperature near the transformer circuit module inside the shell; a battery module for powering the temperature sensor to maintain the temperature sensor's temperature data acquisition operation; and a memory connected to the temperature sensor for storing temperature data. During storage, the data is stored in different states according to the amount of temperature data provided by the temperature sensor. If the data size of the smallest data block is compatible with the storage unit capacity, it is stored directly. If the data size of the data block is less than the storage unit capacity, the data block is placed in a stack module. The stack module accumulates and fills the data until the data size in the stack module is compatible with the storage unit capacity, forming a data block that is stored in the memory.

[0007] The processor module connects to the battery module and the memory, and adjusts the power output and memory storage space based on the amount of temperature data collected.

[0008] The battery module is located below the base and includes multiple intermediate modules. The intermediate modules are connected end to end to form a large ring module. The intermediate module includes multiple small batteries, a ring base, a fixing cover, and terminals. The multiple small batteries are arranged sequentially on the ring base and fixed by the fixing cover. Each small battery has a terminal on the fixing cover. The multiple ring bases are connected end to end to form a large ring module. A rotating shaft is mounted in the center of the large module. A contact plate is sleeved on the rotating shaft. The contact plate is provided with positive and negative terminals and is electrically connected to the terminals of each small battery. The contact plate and the large module rotate synchronously around the rotating shaft. A contact pin is provided on the base. The contact pin abuts against the contact plate to connect one of the small batteries.

[0009] Preferably, a motor is provided on the base, which drives the rotating shaft to rotate so that the touch plate and the large module rotate synchronously. The motor is connected to the processor module to control the rotation angle according to the processor's commands.

[0010] Preferably, the contact plate includes a conductor and an insulator. The radial direction of the contact plate is provided with conductive areas corresponding to the positions and numbers of the small batteries. Conductors are embedded in the conductive areas and connected to the electrodes of the small batteries at the corresponding positions through conductive connections. The positive and negative conductors are separated by an insulator. The upper surface of the conductor is used for conductive connection with the contact pin.

[0011] Preferably, the base has two sets of contact pins: one set is a power supply set for outputting power; the other set is a charging set for charging and storing energy in the small battery.

[0012] Preferably, the processor module is configured with low power B1, medium power B2, and high power B3, real-time power Bt of the small battery, and the data volume of the temperature sensor is configured with low data volume D1, medium data volume D2, and high data volume D3, with real-time data volume Dt. When Dt≤D1, the allocated storage space is reduced.

[0013] If D1 < Dt ≤ D2, determine if the power level satisfies Bt ≥ B1, then maintain the currently allocated storage space; if the power level does not meet the condition, then connect a new small battery by rotating the shaft.

[0014] If D2 < Dt ≤ D3, determine if Bt ≥ B2, then use the first coefficient a1 to increase the allocated storage space. If the power does not meet the condition, then connect the new small battery by rotating the shaft.

[0015] If Dt > D3, determine if Bt ≥ B3, then increase the allocated storage space using the second coefficient a2. If the power level is insufficient, connect a new small battery by rotating the shaft, and a1 <a2;

[0016] When the allocated storage space is reduced, if the amount of temperature data collected exceeds the data capacity of the reduced storage space, the collected temperature data will be preprocessed before storage.

[0017] Preferably, standard storage units are provided, with the capacities of each standard storage unit being R1, R2, and R3 in ascending order. If the amount of temperature data is greater than the preset standard data amount, then storage unit with a data capacity of R3 is used; if the amount of temperature data is equal to the preset standard data amount, then storage unit with a data capacity of R2 is used; if the amount of temperature data is less than the preset standard data amount, then storage unit with a data capacity of R1 is used. The preset standard data amount is the average of the total amount of data within several acquisition cycles.

[0018] Preferably, the collected temperature data is preprocessed, including: obtaining the temperature data value T, presetting the parameter index value T0, the index difference Δt0, and if |T-T0|>Δt0, then the collected temperature value T is removed from the data set obtained within the collection period;

[0019] If the amount of remaining data after removing non-compliant temperature data is less than or equal to 50% of the total data in the cycle, it indicates that too much data has been removed, and the standard parameter difference Δd0 should be increased.

[0020] If, after removing non-compliant air pollutant concentrations, the remaining data is greater than 50% of the total data within the period, it indicates that the amount of data removed is appropriate, and the air pollutant concentrations should be stored.

[0021] Preferably, increasing the standard parameter difference Δt0 includes forming a new standard parameter difference Δt, where Δt = 1.1Δt0.

[0022] Preferably, the motor is a servo motor or a stepper motor.

[0023] Preferably, when the processor module determines that Bt is less than B0, 0 < B0 < B1, the processor module controls the connection of the next small battery.

[0024] Compared with the prior art, the technical effects of the present invention are mainly reflected in the following aspects:

[0025] 1. Ordinary electronic transformers only have simple temperature monitoring and storage functions, without optimizing or improving power supply and storage allocation. In contrast, this solution designs a temperature sensor to monitor the ambient temperature on the underlying hardware structure, while using a battery module for power supply. Temperature data is stored in a memory, and a processor module allocates and controls the data storage, adjusting the power supply and storage space according to the amount of data. This scheduling method can greatly save hardware storage resources, improve storage space utilization, effectively save energy, expand power supply capacity, allow the battery module to provide power for longer periods, and avoid wasting electricity. It also allows for reliable power supply allocation based on the amount of data and the data space.

[0026] 2. The power supply module uses a mechanical structure to fix the small batteries, which are arranged in a ring shape. They can rotate and switch in a cycle, and have the effect of separating and independently discharging and charging.

[0027] 3. By selecting data volume in intervals and power consumption based on conditions, the utilization of data storage space and energy saving effect can be effectively improved.

[0028] 4. Adopt a reliable data preprocessing scheme to improve data reliability, save resources, remove invalid data, and reduce the data storage burden. Attached Figure Description

[0034] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and mastered.

[0035] Example:

[0036] A high-frequency self-oscillating electronic transformer, reference Figure 1 As shown, the circuit includes a base 1, a housing 2, a self-excited oscillation circuit 3 vertically fixed on the base 1, and a transformer circuit module 4. The self-excited oscillation circuit 3 and the transformer circuit module 4 are existing structures in the circuit. The specific self-excited oscillation circuit 3 and the transformer circuit module 4 can be commercially available circuit modules. The transformer circuit module 4, due to its internal transformer, generates significant heat.

[0037] Combination Figure 3Understanding this structure, this solution differs from others in that it also includes a temperature sensor 5, used to collect the ambient temperature near the transformer circuit module 4 inside the casing 2. A battery module 6 powers the temperature sensor 5, enabling it to collect temperature data. A memory 7 connects to the temperature sensor 5 to store the temperature data. During storage, the memory is divided into states based on the amount of temperature data provided by the temperature sensor 5. If the minimum data block size matches the storage unit capacity, it is stored directly. If the data block size is less than the storage unit capacity, it is placed in the stack module. The stack module accumulates and pads the data until the data volume matches the storage unit capacity, forming a data block that is stored in the memory 7. In microcontroller applications, the stack is a special storage area primarily used to temporarily store data and addresses, typically for protecting breakpoints and the current state. A stack is a specific storage area or register, with one end fixed and the other floating. The data stored in this storage area is a special data structure. All data storage and retrieval can only occur at one end of the stack (the top), strictly following the "last-in, first-out" principle. Elements in the middle must be removed only after all elements pushed onto the stack later have been removed. A region within main memory 7 (random access memory 7) is allocated as the stack, called the software stack; a stack constructed using registers is called the hardware stack. This scheme utilizes its caching function, enabling temporary data storage and data volume management.

[0038] The processor module 8 is connected to the battery module 6 and the memory 7, and adjusts the power output capacity and the storage space of the memory 7 according to the amount of temperature data collected.

[0039] Back Figure 1 , Figure 4The battery module 6 is located below the base 1 and includes multiple intermediate modules 62, which are connected end-to-end to form a large ring-shaped module 61. Each intermediate module 62 includes multiple small batteries 621, a ring-shaped base 622, a fixing cover 623, and terminals 624. The multiple small batteries 621 are arranged sequentially on the ring-shaped base 622 and fixed to each small battery 621 by the fixing cover 623. The fixing cover 623 is not conductive; its function is to secure each small battery 621. Each small battery 621 has a positive terminal 641 and a negative terminal 642. The positive terminal 641 and the negative terminal 642 are electrically connected via wires or terminals 624. Specifically, each small battery 621 has terminals 624 at both ends of the fixing cover 623. Each small battery 621 has a terminal 624 on the fixing cover 623. The terminals 624 are then connected to the contact plate 64 via wires (not shown in the attached diagram). Multiple ring-shaped bases 622 are connected end to end to form a large ring module 61. A rotating shaft 63 is mounted at the center of the large module 61, and a contact plate 64 is sleeved on the rotating shaft 63. The contact plate 64 is provided with a positive electrode 641 and a negative electrode 642, which are electrically connected to the terminals 624 of each small battery 621. The contact plate 64 and the large module 61 rotate synchronously around the rotating shaft 63. A contact pin 110 is fixedly mounted on the base 1, and the contact pin 110 abuts against the contact plate 64 to connect one of the small batteries 621.

[0040] Based on the above scheme, a motor 9 is provided on the base 1. The motor 9 drives the rotating shaft 63 to rotate, so that the contact plate 64 and the large module 61 rotate synchronously. The motor 9 is connected to the processor module 8 to control the rotation angle according to the processor's commands. The contact plate 64 includes a conductor 643 and an insulator 644. The radial direction of the contact plate 64 is set with conductive areas corresponding to the positions and numbers of the small batteries 621. The conductors 643 are embedded in the conductive areas and are conductively connected to the electrodes of the small batteries 621 at the corresponding positions. The positive electrode 641 conductor 643 and the negative electrode 642 conductor 643 are separated by the insulator 644. The upper surface of the conductor 643 is used for conductive connection with the contact pin 110. The design of the contact plate 64 makes it easier to power the small batteries 621 and allows for power switching. The motor 9 is a servo motor 9 or a stepper motor 9.

[0041] exist Figure 1 As can be seen, the base 1 has two sets of contact pins 110: one is a power supply group 101, used for outputting power; the other is a charging group 102, used for charging and storing energy in the small battery 621. In this design, the electrodes on the contact plate 64 are arranged circumferentially in multiple groups, the number corresponding to the number of small batteries 621 below. Figure 1 The diagram illustrates the principle, and those skilled in the art can understand its working principle.

[0042] Ordinary electronic transformers only have simple temperature monitoring and storage functions, without optimizing or improving power supply and storage allocation. In contrast, this solution incorporates a temperature sensor 5 to monitor ambient temperature within its hardware structure, powered by a battery module 6. Temperature data is stored in a memory 7, and a processor module 8 controls the allocation of data storage, adjusting power supply and storage space according to the data volume. This scheduling method significantly saves hardware storage resources, improves storage space utilization, effectively saves energy, expands power supply capacity, allows the battery module 6 to provide power for longer periods without wasting electricity, and reliably allocates power based on data volume and space. The power supply module uses a mechanical structure to fix the small batteries 621, arranged in a ring, allowing for cyclical switching and providing independent discharge and charging capabilities.

[0043] Based on the above scheme, the internal configuration processing method of processor module 8 also includes: processor module 8 is set with low power B1, medium power B2, high power B3, real-time power Bt of small battery 621, and data volume of temperature sensor 5 is set with low data volume D1, medium data volume D2, high data volume D3, and real-time data volume Dt. When Dt≤D1, the allocated storage space is reduced; if D1<Dt≤D2, it is determined that the power satisfies Bt≥B1, and the currently allocated storage space is maintained; if the power does not meet the condition, a new small battery 621 is connected by rotating the shaft 63; if D2<Dt≤D3, it is determined that Bt≥B2, and the allocated storage space is increased using the first coefficient a1; if the power does not meet the condition, a new small battery 621 is connected by rotating the shaft 63; if Dt>D3, it is determined that Bt≥B3, and the allocated storage space is increased using the second coefficient a2; if the power does not meet the condition, a new small battery 621 is connected by rotating the shaft 63, and a1 <a2。

[0044] When the allocated storage space is reduced, if the amount of temperature data collected exceeds the data capacity of the reduced storage space, the collected temperature data will be preprocessed before storage.

[0045] Standard storage units are set up, with the capacities of each standard storage unit ranging from smallest to largest as R1, R2, and R3. If the amount of temperature data is greater than the preset standard data amount, then storage unit with a data capacity of R3 is used; if the amount of temperature data is equal to the preset standard data amount, then storage unit with a data capacity of R2 is used; if the amount of temperature data is less than the preset standard data amount, then storage unit with a data capacity of R1 is used. The preset standard data amount is the average of the total amount of data over several acquisition cycles.

[0046] The collected temperature data undergoes preprocessing, including obtaining the temperature value T, presetting the parameter index value T0, and the index difference Δt0. If |T-T0|>Δt0, the collected temperature value T is removed from the dataset acquired within the collection period. If, after removing non-compliant temperature data, the remaining data volume is ≤50% of the total data volume within the period, it indicates excessive data removal, and the standard parameter difference Δd0 is increased. If, after removing non-compliant air pollutant concentrations, the remaining data volume is >50% of the total data volume within the period, it indicates a moderate amount of data removal, and the air pollutant concentrations are stored. This preprocessing method reduces the data volume and eliminates invalid data, making temperature data storage more accurate and reliable. The streamlined data also facilitates efficient use of storage space.

[0047] Increase the standard parameter difference Δt0, including forming a new standard parameter difference Δt, Δt=1.1Δt0.

[0048] When processor module 8 determines that Bt is less than B0 (0 < B0 < B1), processor module 8 controls the connection of the next small battery 621. This effectively improves data reliability in the event of data deviation.

[0049] By segmenting data volumes into intervals and selecting power consumption criteria, the utilization of data storage space and energy efficiency can be effectively improved. A reliable data preprocessing scheme is employed to enhance data reliability, conserve resources, eliminate invalid data, and reduce the burden on data storage.

[0050] As can be seen from the overall effect of the above scheme, this scheme allocates storage space more rationally based on the amount of temperature data, improves the utilization efficiency of memory 7, and is more energy-efficient while improving performance. The power consumption of the small battery 621 is identified, and feedback and control are made based on the power level. The control method is that if the power is very low, the next small battery 621 will be switched to maintain power supply for a single small battery 621. For large amounts of data storage, a fully charged small battery 621 is required; if the amount of data is small, a small battery 621 with medium or low power can be used, thus saving energy and reducing consumption. Simultaneously, the low-powered battery can be charged and stored.

[0051] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
