[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0024] A fire hydrant monitoring terminal, installed in the cap of the fire hydrant, includes:
[0025] The main control MCU module is integrated on the main control board of the fire hydrant monitoring terminal. It communicates with the integrated management platform and sends the calculated and processed information to the integrated management platform.
[0026] The main control MCU module is the MN316-DLVD communication module. It supports Cat.1 communication networks and can send and receive data to and from the integrated management platform via a wireless network. Because the MN316-DLVD communication module supports OPENCPU functionality, it can function not only as a communication module but also as a processing CPU. When used as a CPU, it processes and analyzes data collected by the satellite positioning module, displacement detection module, and water pressure detection module.
[0027] Cat.1 technology is a modulation and coding technique within LTE (Long-Term Evolution) technology, and its origins can be traced back to the development of LTE technology. In 2007, the 3rd Generation Partnership Project (3GPP) began developing the LTE standard, aiming to provide higher data transmission rates, lower latency, and better spectrum utilization. During the 3GPP standard development process, to meet the needs of IoT devices, a connectivity technology suitable for low-power, low-bandwidth application scenarios needed to be developed, and thus Cat.1 technology emerged. Cat.1 technology can provide relatively high data transmission rates while also featuring low power consumption and low cost, offering a better solution for IoT device connectivity. Therefore, Cat.1 technology can be seen as an optimization and extension of LTE technology specifically for IoT devices.
[0028] The satellite positioning module is integrated on the main control board of the fire hydrant monitoring terminal. It is connected to the main control MCU via a UART serial port and communicates with the main control MCU module to transmit the collected location and time parameters to the main control MCU module.
[0029] The satellite positioning module uses the AT6558R-5N32 satellite positioning module chip from Zhongke Microelectronics. It connects to the main control MCU module via a UART serial port. It is typically in sleep mode, activating upon receiving a command from the main control MCU. It then sends a data set including latitude and longitude coordinates, time, and time zone to the main control MCU module via the UART serial port before re-entering sleep mode.
[0030] UART serial communication, or Universal Asynchronous Receiver / Transmitter, is a universal serial data bus used for asynchronous communication. This bus enables bidirectional communication, allowing for full-duplex transmission and reception.
[0031] The displacement detection module is integrated on the main control board of the fire hydrant monitoring terminal. It is connected to the main control MCU via the SPI interface and the main control MCU module, and transmits the collected displacement and attitude parameters to the main control MCU module.
[0032] The displacement detection module uses the STMicroelectronics LIS2DH12TR attitude sensor chip. It connects to the main control MCU module via the I²C communication bus protocol. When the acceleration generated by the device in the X, Y, or Z axis directions exceeds the set threshold, it will actively send the collected displacement data to the main control MCU module via the I²C communication bus.
[0033] I²C, short for Integrated Circuits, is a serial communication bus that uses a multi-master / slave architecture. It was developed by Philips in the 1980s to allow motherboards, embedded systems, and mobile phones to connect low-speed peripheral devices. I²C uses only two bidirectional open-collector terminals (Serial Data (SDA) and Serial Clock (SCL)) and pulls the voltage up using resistors. I²C allows for a fairly wide operating voltage range, but typical voltage levels are +3.3V or +5V.
[0034] The water pressure detection module is installed in the fire hydrant and connected to the main control MCU module to transmit the collected water pressure information in the fire hydrant to the main control MCU module; the water pressure detection module uses the WF5803F 14BA L8 DT chip.
[0035] The voltage regulator module is connected to the main control MCU module, satellite positioning module, water pressure detection module and displacement detection module respectively, and converts the output voltage of the lithium battery into the DC 3.3V working voltage used by the device.
[0036] The voltage regulator module uses the WD1020C voltage regulator chip from Will Semiconductor. This is an ultra-low quiescent current buck converter with a typical quiescent current of 360 nA. The device exhibits high efficiency under light loads as low as 10 μA, with an input voltage range of 2.2 V to 5.5 V and a programmable output voltage between 1.2 V and 3.3 V. The WD1020C can also provide up to 600 mA of output current, with a peak current of 1.2 A. This meets the peak current requirement of 200 mA for the main control MCU during communication tasks.
[0037] This utility model is as follows Figure 1-6 As shown, the fire hydrant monitoring terminal operates as follows:
[0038] An external 3.7V / 4.2V lithium battery is used, and the voltage is stabilized to 3.3V by a voltage regulator module, which then powers the main control MCU module, satellite positioning module, displacement detection module, and water pressure detection module. After power-on, the main control MCU module sends login information to the integrated management platform via the wireless network. The platform confirms the login and issues a confirmation command. Upon receiving the confirmation command, the main control MCU module enters normal operation. Once the fire hydrant monitoring terminal is installed, the integrated management platform issues an initialization command. Upon receiving this command, the main control MCU sends latitude and longitude acquisition commands to the satellite positioning module via the UART serial port, and initialization commands to the displacement detection module and water pressure detection module via the I²C serial port. After initialization, the satellite positioning module, displacement detection module, and water pressure detection module send their initialization data back to the main control MCU, which then sends all the initialization data back to the integrated management platform. Afterward, the terminal enters normal working state. The main control MCU will periodically send monitoring data to the satellite positioning module, displacement detection module, and water pressure detection module, and then process the data returned by each module and send it back to the integrated management platform. When the equipment is in normal working state, if the fire hydrant changes position due to external force, the displacement detection module will actively activate and collect data to report to the main control MCU module. The main control MCU module will then send an alarm message to the integrated management platform.
[0039] Compared to existing technologies, this utility model provides a fire hydrant monitoring terminal with remote communication capabilities, which can be used to remotely monitor the status and location information of fire hydrants, greatly reducing the workload of personnel. In case of emergencies, the terminal will promptly transmit alarm information for timely handling, which greatly reduces the risk of accidents. The use of the fire hydrant monitoring terminal can improve the emergency response and handling capabilities of management enterprises, save a lot of financial and material resources, improve the efficiency of quickly analyzing and handling pipeline network faults, and lay a solid foundation for the construction of a smart pipeline network sensing layer.
