Description

Technical Field

[0001] This utility model relates to the field of flood warning technology, specifically to a low-power flood warning device based on LTE Cat.1 real-time image transmission. Background Technology

[0002] Currently, flood warning devices mostly use NB-IoT network communication to achieve low power consumption and long battery life. However, due to the vigorous development of LTE Cat.1 networks by operators in recent years and the continuous upgrading of LTE Cat.1 technology, LTE Cat.1 can also achieve large bandwidth data transmission with relatively low energy consumption. Furthermore, due to the transformation of base stations, the NB-IoT network has shrunk to a certain extent. At the same time, the limited application of NB-IoT networks has resulted in insufficient coverage, leading to many areas being unable to connect to NB-IoT networks, especially remote areas. In contrast, LTE networks have a wider coverage. Therefore, many applications are now switching from NB-IoT networks to LTE Cat.1.

[0003] In addition, for special scenarios like flood warning devices, when the device alarms, it is impossible to know whether there is actually water accumulation on site, how deep the water is, and how much impact it has. These questions cannot be answered from a single flood alarm signal. Therefore, many existing solutions use external cameras to view the scene and determine the impact of flooding. However, external cameras are troublesome to install, costly, have complex power supply requirements, and are inconvenient.

[0004] Based on this, this utility model designs a low-power flood warning device based on LTE Cat.1 real-time image transmission to solve the above problems. Utility Model Content

[0021] Furthermore, the main control module uses a microcontroller of model STM32G0B1RET6;

[0022] Furthermore, the LTE Cat.1 module uses a communication module of model number Quectel EC800ECNLF.

[0023] Compared with the prior art, the advantages of this utility model are as follows: 1. By using LTE Cat.1 communication, the device has a larger communication bandwidth, making it possible to transmit data such as pictures and videos, and the communication speed is faster;

[0024] 2. Since LTE signal coverage is almost complete, there are fewer busy points and a wider range of equipment installation scenarios. It has a greater advantage, especially in places such as garages, basements, and pump rooms where there is basically no NB-IoT signal.

[0026] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0027] Figure 1 This is a schematic diagram of the component circuit structure of a low-power flood warning device based on LTE Cat.1 real-time image transmission according to this utility model. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figure 1 A low-power flood warning device based on LTE Cat.1 real-time image transmission includes a power supply component, as well as a reverse connection protection circuit, a step-down module, a step-up module, an LTE Cat.1 module, a main control module, a USB camera module, and a sensor component;

[0030] The power supply component is electrically connected to the reverse connection protection circuit; the reverse connection protection circuit is electrically connected to the buck module and the boost module; and the reverse connection protection circuit is electrically connected to the LTE Cat.1 module.

[0031] The step-down module is electrically connected to the main control module; the boost module is electrically connected to the USB camera module; the USB camera module is connected to the main control module via serial communication.

[0032] Furthermore, the main control module is electrically connected to the boost module;

[0033] Furthermore, the LTE Cat.1 module and the main control module are connected via serial communication.

[0034] The LTE Cat.1 module is electrically connected to an external host platform;

[0035] The sensor assembly used to detect whether the device has been flooded is electrically connected to the main control module.

[0036] In this invention, the LTE Cat.1 module and the USB camera module are enabled and disabled by the main control module. Under normal operation, the USB camera module is always powered off, thus achieving relatively low power consumption.

[0037] When the sensor components detect water damage to the device, the main control module activates the USB camera module and the boost module. This allows the power supply components to power the USB camera module through the reverse connection protection circuit and the boost module. The USB camera module then acquires image data and transmits it to the main control module. Subsequently, the main control module shuts down the USB camera module and sends the image data to the host computer platform via the LTE Cat.1 module. Because LTE Cat.1 has a larger bandwidth than NB-IoT, image data transmission can be completed faster. After the data transmission is complete, the main control module shuts down the LTE Cat.1 module.

[0038] The LTE Cat.1 communication method enables the device to have greater communication bandwidth, making it possible to transmit data such as pictures and videos, and the communication speed is faster. Moreover, since LTE signal coverage is almost all-encompassing, there are fewer signal busy points, making the device more versatile in installation scenarios. It has a greater advantage, especially in places where there is little NB-IoT signal, such as garages, basements, and pump rooms. Furthermore, the USB camera module is built into the flood warning device and directly connected to the main control module, which reduces the cost of image data acquisition and simplifies the installation and deployment process.

[0040] The boost module is composed of a DC-DC power chip, which is electrically connected to the USB camera module.

[0041] The step-down module is composed of an LDO power chip, which is electrically connected to the main control module.

[0042] The LTE Cat.1 module communicates with the main control module via a UART (Universal Asynchronous Receiver Transmitter) serial port.

[0043] The USB camera module communicates with the main control module via a USB (Universal Serial Bus) serial port.

[0044] The main control module uses a microcontroller of model STM32G0B1RET6;

[0045] The LTE Cat.1 module uses a Quectel EC800ECNLF communication module for data transmission;

[0046] In this invention, the LDO power chip reduces the 3.6V output voltage of the lithium ammonium battery to 3.3V to meet the power supply voltage requirements of the main control module; and the DC-DC power chip can boost the 3.6V output voltage of the lithium ammonium battery to 5V to meet the power supply voltage requirements of the USB camera module.
