Technical Field

[0002] Among the current mainstream unit valve communication technologies, the RS485 wired solution requires pre-buried cables for data transmission. While feasible in indoor manhole scenarios, it faces engineering challenges such as road surface damage and cable maintenance difficulties when deployed in outdoor underground manholes. The NB-IoT wireless solution eliminates wiring but is limited by operator network coverage, with frequent signal interruptions in underground and remote areas leading to low command transmission success rates. While the LoRaWAN wireless solution offers stable communication capabilities, its self-built private network requires high-cost gateway equipment, causing a surge in per-valve costs in small-scale unit valve deployments, severely hindering commercial adoption. These three technologies each suffer from core drawbacks such as high construction destructiveness, low signal reliability, and economic imbalance, necessitating the development of low-cost hybrid networking technologies adapted to distributed scenarios to overcome existing bottlenecks.

[0030] Example 1, combined with Figure 1 This embodiment is described. A 4G low-power unit valve includes: a control board, a housing, and an antenna;

[0031] The control board is fixed inside the housing, and the antenna is fixed outside the housing by a threaded connection. The control board uses an antenna adapter cable to transmit signals to the antenna.

[0032] The control board includes: a lithium battery pack, a charging control unit, a power management unit, a storage unit, a clock unit, a 4G module, an SD card driver unit, a display unit, and a main control unit;

[0033] The main control unit is used to receive electrical energy from the lithium battery pack through the charging control unit, and to control the charging control unit through the power management unit to achieve intelligent power distribution;

[0034] The main control unit is used to exchange data with the storage unit;

[0035] The main control unit is used to achieve time scheduling and synchronization through the clock unit;

[0036] The main control unit is used to achieve low-power remote direct transmission of valve data to the cloud via the 4G module;

[0037] The main control unit is used to read or write configuration parameters in the SD card through the SD card driver unit to realize the management and updating of valve configuration;

[0038] The main control unit is also used to dynamically refresh and visualize the battery level, 4G signal strength, and valve opening through the display unit.

[0039] Specifically, in combination Figure 1It is understood that the control board coordinates the collaborative work of multiple modules through an integrated main control unit: power is supplied by a lithium battery pack via a charging control unit, and the power management unit dynamically optimizes energy consumption allocation to extend battery life; the main control unit backs up valve opening, fault logs, and configuration parameters in real time through a storage unit, synchronizes clock signals to achieve precise task scheduling, and directly uploads valve operation data to the cloud via a 4G module, bypassing the traditional gateway layer and reducing communication latency; simultaneously, offline updates of local configurations are achieved through an SD card driver unit, and the display unit provides real-time visual feedback on power consumption, signal strength, and valve status, forming an intelligent valve control architecture that combines low power consumption, remote direct connection, and autonomous configuration and maintenance capabilities, effectively solving the technical problems of complex wiring, strong signal dependence, and high maintenance costs in traditional solutions. Figures 2-4 The specific structure of the outer shell in this utility model is known.

[0040] Furthermore, the lithium battery pack adopts a 3-series-4-parallel configuration, with a power supply of 14V and a capacity of 19AH.

[0041] Furthermore, the charging control unit uses a CN3762 chip.

[0042] Specifically, in combination Figure 5 It is known that the charging control unit uses the CN3762 chip to achieve efficient and safe charging management of multiple lithium batteries. This chip can accurately adapt to the 14V charging voltage requirement of a 3-cell lithium battery pack, providing underlying energy security for the long-term autonomous operation of the system in scenarios without external power supply.

[0043] Furthermore, the SD card driver unit uses a CH376S chip.

[0044] Specifically, the SD card driver unit uses the CH376S chip to achieve efficient file system-level storage management, which is adapted to the needs of valve field firmware upgrades, log recording and multi-version configuration backup, greatly improving the system's offline maintenance efficiency and data risk resistance.

[0045] Furthermore, the main control unit uses an STM32L151 microprocessor.

[0046] Specifically, the use of the STM32L151 high-performance microprocessor provides this invention with high performance, low power consumption, and strong anti-interference capabilities, thereby ensuring the long-term stable operation of this invention.

[0047] Furthermore, the storage unit adopts an FM25V05 ferroelectric memory.

[0048] Specifically, the FM25V05 ferroelectric memory is a non-volatile memory chip with a write / erase cycle of up to 1 million. This memory unit enables the valve to automatically resume operation in its previous state after a power outage and subsequent power restoration.

[0049] Furthermore, the 4G module adopts WH-LTE-7S1.

[0050] Specifically, the 4G module achieves low-power, highly compatible wide-area IoT communication using WH-LTE-7S1. It employs the TCP communication protocol, requiring the specification of a server IP address and port number for data interaction with the cloud platform. The TCP protocol data packet portion uses a proprietary design, and the module interacts and parses with the platform according to this customized protocol. Simultaneously, the 4G module has a 4G network disconnection reconnection function. If the valve does not receive confirmation data from the cloud platform when reporting data, the valve will automatically restart the 4G module and re-enter the network to report data. During non-reporting periods, the 4G module will automatically shut down to conserve power.

[0051] Furthermore, the clock unit uses a PC8563T chip.

[0052] Specifically, in combination Figure 6 It is known that the clock unit uses a PC8563T chip to provide a high-precision, low-power real-time clock reference for the valve system, driving the main control unit to wake up the 4G module for data upload according to a preset cycle. In conjunction with the dynamic sleep strategy of the power management unit, it provides key timing control support for the valve's ultra-long battery life in scenarios without external power supply.

[0053] Furthermore, the display unit uses a segmented LCD screen.

[0054] Specifically, the display unit uses a 1 / 8-degree, 1 / 3-base, full-view segment LCD screen, which can display many parameters without occupying too many LCD screen pins.
