Description

Technical Field

[0001] This application relates to the field of electromagnetic signal transmission technology, and specifically discloses a wide-area electromagnetic interval transmission device based on solar power. Background Technology

[0002] With the increasing demand for long-term field observation equipment in fields such as earthquake monitoring, geological exploration, and environmental monitoring, the technology of electromagnetic transmission devices powered by solar energy has developed rapidly. For example, the construction of large-scale monitoring networks such as the China Earthquake Science Experimental Field has promoted the development of new field earthquake observation methods, including advanced equipment such as the ground receiving station of the electromagnetic monitoring experimental satellite tri-frequency beacon system and the AETA multi-component earthquake monitoring system.

[0003] However, many challenges and limitations still exist in the actual application of various monitoring systems:

[0004] Firstly, continuous transmission mode results in excessive power consumption and insufficient battery life. Traditional electromagnetic launching devices generally employ continuous transmission mode, which, while advantageous in specific application scenarios, suffers from significant power consumption drawbacks. Traditional deep-sea towed launching devices, such as marine controlled-source launching systems, can operate continuously, but their enormous power consumption makes them unsuitable for long-term field operations. In ultra-low frequency (ULF) launching systems, existing transmitters primarily use sinusoidal oscillators, which exhibit poor frequency stability and limited power consumption control. In continuous transmission mode, the repetitive emission of electromagnetic pulses causes continuous electromagnetic energy output, leading to rapid battery depletion and failing to meet the practical needs of long-term field monitoring.

[0005] Secondly, traditional power supply methods have limitations. Existing field electromagnetic launch equipment mainly relies on battery power or external power lines. When deployed in remote areas, it faces problems such as difficulty in setting up power lines, frequent battery replacement, and high maintenance costs, which seriously restricts the practicality of the equipment.

[0006] In view of the above, this utility model provides a wide-area electromagnetic interval transmitting device based on solar power to solve the above problems. Utility Model Content

[0009] Furthermore, the wide-area electromagnetic timing transmitter integrates a high-precision digital signal processor and a signal input unit, and the clock circuit is connected to the high-precision digital signal processor to control the wide-area electromagnetic timing transmitter to transmit at the specified time.

[0010] Furthermore, the energy storage battery is equipped with a charging output interface for powering a high-precision digital signal processor.

[0011] Furthermore, the output voltage of the charging output interface is 16.8V, and the output voltage of the inverter is 220V.

[0012] Furthermore, it also includes poles for supporting the solar panels and mounting boxes for housing energy storage batteries and controllers.

[0013] Furthermore, the mounting box is mounted on the column and located below the solar panel.

[0014] Furthermore, the mounting box is also equipped with a backup power supply that powers the wide-area electromagnetic timing transmitter and inverter and is controlled by the controller.

[0015] The principle and effect of this solution are as follows:

[0016] 1. Significantly improved endurance: By combining solar panels with interval transmission, the equipment can operate autonomously for months or even years, completely solving the technical problem of insufficient endurance of traditional equipment in the field.

[0017] 2.

[0024] The reference numerals in the accompanying drawings include: pole 1, solar panel 2, mounting box 3, inverter 4, DC regulated power supply 5, wide-area electromagnetic timing transmitter 6.

[0025] A solar-powered wide-area electromagnetic interval transmitting device, implementing, for example... Figure 1 As shown: including a solar panel 2 for converting solar energy into electrical energy, an energy storage battery for storing the electrical energy converted by the solar panel 2, an inverter 4 for converting the electrical signals in the energy storage battery into stable 220V DC power, a DC regulated power supply 5 for receiving the power from the inverter 4 and transmitting excitation signals, a wide-area electromagnetic timing transmitter 6 for receiving the excitation signals from the DC regulated power supply 5 and transmitting electromagnetic waves, a controller that is connected to the solar panel 2, the energy storage battery, the DC regulated power supply 5, and the wide-area electromagnetic timing transmitter 6, a clock circuit that is electrically connected to the controller and controls the timing transmission of the wide-area electromagnetic timing transmitter 6, and a support pole 1 for supporting the solar panel 2.

[0026] Solar panel 2 is the main energy input unit, responsible for converting solar radiation energy into electrical energy. Under sunlight conditions, solar panel 2 generates direct current through the photovoltaic effect, and the output voltage and current vary with the intensity of sunlight.

[0027] The controller integrates a battery management system module and a charging control module to monitor the energy storage battery. The battery receives electrical energy from the solar panel 2 and stores it as low-voltage DC power. The battery management system and charging control module optimize the charging management of the energy storage battery, preventing overcharging, over-discharging, and other abnormalities, ensuring safe and stable battery operation. Simultaneously, Hall effect sensors and voltage transformers are used to collect the voltage and current signals of the energy storage battery, feeding these signals back to the controller. The controller controls the charging and discharging circuit through a MOSFET switching module, enabling it to also perform power monitoring, load management, and other functions, monitoring the system's power status in real time.

[0028] The solar panel 2, the energy storage battery, and the controller are all supported and fixed by the pole 1. The energy storage battery and the controller are configured in the mounting box 3 located below the solar panel 2 to protect the energy storage battery and the controller and ensure the mechanical stability of the equipment in the outdoor environment.

[0029] The energy storage battery is equipped with a charging output interface, which provides 16.8V DC power to the high-precision digital signal processor built into the wide-area electromagnetic timing transmitter 6. The inverter 4 converts the low-voltage DC power output from the energy storage battery into 220V AC power and provides working power to the DC regulated power supply 5 through the power supply interface. The DC regulated power supply 5 serves as the excitation signal source for the electromagnetic transmitter and is responsible for providing stable and adjustable DC voltage and current to the wide-area electromagnetic timing transmitter 6 to ensure the stability and consistency of electromagnetic signal transmission.

[0030] The wide-area electromagnetic timing transmitter 6 is the execution unit, which integrates a high-precision digital signal processor, clock circuit, signal input unit, etc. The set parameters are manually input to the controller and high-precision digital signal processor through touch screen, buttons, etc., to adjust the amplitude of the output voltage and current of the DC regulated power supply 5, waveform generation, frequency control, timing management and other functions of the wide-area electromagnetic timing transmitter 6.

[0031] This enables the wide-area electromagnetic timing transmitter 6 to generate various types of electromagnetic waveforms, including single-frequency and multi-frequency waves, covering a wide frequency range from low to high (1Hz to 64kHz). Furthermore, the waveform parameter setting function allows users to flexibly configure key parameters such as the frequency, amplitude, and frequency point of the transmitted signal according to specific application requirements. The time control parameter setting enables precise timed transmission management; users can set time parameters such as the transmission start time, duration, and interval period, and the system will automatically execute the transmission task strictly according to the preset schedule.

[0032] Correspondingly, a backup power supply controlled by a controller is configured in the installation box 3 to power the wide-area electromagnetic timing transmitter 6, inverter 4, etc. when the energy storage battery is insufficient.

[0033] like Figure 2 As shown, in this embodiment, the solar panel 2 continuously charges the energy storage battery to ensure sufficient energy reserves. When the preset transmission time is reached, the clock circuit automatically activates the transmission process through a high-precision digital signal processor: adjusting the output parameters to the target value; then activating the wide-area electromagnetic timing transmitter 6, generating and transmitting electromagnetic signals through the electrode antenna according to preset waveform parameters; after the transmission is completed according to the predetermined time, the wide-area electromagnetic timing transmitter 6 is turned off and enters standby mode to wait for the next transmission cycle. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model in any way. Although this utility model has been disclosed above with preferred embodiments, it is not intended to limit this utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
