Description

Technical Field

[0001] This invention belongs to the field of network information technology, specifically a research and development method and system for a low-power, high-stability router. Background Technology

[0002] With the widespread adoption of smart homes, remote work, and outdoor IoT monitoring, routers, as core network access devices, have expanded their application scenarios from traditional homes to complex environments such as industrial outdoor areas and remote regions.

[0003] However, existing router products face two major challenges: The problem of excessive power consumption is prominent: Traditional routers adopt a continuous high-load operation mode, with standby power consumption reaching 5-10W. Long-term operation results in high energy costs and they cannot adapt to outdoor low-power scenarios such as solar power and battery power.

[0004] Therefore, this invention provides a method and system for developing a low-power, high-stability router. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] Firstly, the technical solution adopted by the present invention to solve its technical problem is: a research and development method for a low-power, high-stability router, comprising the following steps: Step 1: Use low-power hardware to optimize power consumption at the hardware level and build an energy-efficient hardware architecture; Step 2: Using low-power chips, compare the computing power, power consumption, and compatibility of MediaTek, Qualcomm, and Rockchip low-power chips, and select a high-performance low-power chip with standby power consumption ≤0.5W and full load power consumption ≤3W. Step 3: The power management module integrates a DC-DC converter and a power management chip (PMIC), supports wide voltage input (5~48VDC), and has self-sleep and dynamic voltage regulation functions; Step 4: Low power optimization of RF module: Low power RF front-end components are adopted, and an adaptive power adjustment circuit is designed to dynamically adjust the transmission power according to the device access distance, with the transmission power ranging from 0.1 to 20 dBm; Step 5: Structure and heat dissipation design: A fanless passive heat dissipation structure is adopted, combined with a high thermal conductivity shell material to reduce heat dissipation energy consumption; the outdoor version adopts an IP67 protection level shell, which is suitable for a wide temperature range of -40℃ to 70℃.

[0007] Preferably, step 2 includes the following steps: When the low-power chip is in deep sleep mode, it greatly reduces power consumption while retaining RTC and RAM. When the router wakes up the low-power chip later, it can be woken up with very low current.

[0008] Preferably, step 4 includes the following steps: The low-power optimization of the radio frequency module includes a multi-mode wake-up mechanism and automated transmit / receive switching; The multi-mode wake-up mechanism utilizes the module's built-in hardware wake-up, serial port wake-up, or over-the-air (WOR) wake-up functions. In the chip's sleep state, the chip consumes only a very low standby current, and the RF circuit is only started momentarily when a specific signal is detected.

[0009] Preferably, step 4 further includes the following steps: Automated transmit / receive conversion: Select a module that supports half-duplex and can automatically complete transmit / receive conversion; after data transmission is completed, the module can automatically switch back to low-power monitoring or sleep mode without MCU intervention.

[0010] Secondly, a research and development system for a low-power, high-stability router, the research and development system comprising: The intelligent power consumption scheduling module is used to allow the router to switch between high-performance mode and low-performance mode when the router's workload is high and low. The high stability enhancement module is designed to maintain extremely high signal penetration and electromagnetic interference resistance even under electromagnetic interference, harsh outdoor environments, sudden hardware and network failures, ensuring stable and smooth network operation in harsh industrial, indoor and outdoor environments. The environmental sensing and adaptive unit is used to sense the temperature of the external environment and automatically adjust the router's operating mode when the temperature exceeds a threshold.

[0011] Preferably, the intelligent power consumption scheduling module includes a load sensing scheduling unit, a fault self-healing unit, and a protocol optimization unit; When the router is under high load, the load-aware scheduling unit will immediately wake up hardware modules that are in hibernation or low-power operation to increase the CPU clock frequency.

[0012] When the workload is low, if the system detects only a small number of heartbeat packets or low-speed data, it will automatically shut down redundant hardware modules and reduce the CPU frequency.

[0013] Preferably, the protocol optimization unit adopts an energy-saving sleep state to optimize the WiFi and Ethernet protocol transmission mechanisms, thereby reducing air interface occupation and power consumption.

[0014] Preferably, the high stability enhancement module includes: The anti-interference communication unit adopts frequency hopping communication technology and signal enhancement filtering circuit, combined with an omnidirectional high-gain antenna, to improve signal penetration and anti-electromagnetic interference capability.

[0015] Preferably, the fault self-healing unit: detects the network connection status in real time; when a hardware module or communication link failure is detected, it automatically triggers the network disconnection and reconnection mechanism and switches to the backup communication link or hot backup module to ensure service continuity.

[0016] Preferably, the frequency hopping communication is used when a router in a certain frequency band is subjected to strong electromagnetic interference. This frequency hopping communication enables the communication signal to periodically switch between different frequencies, thereby avoiding the interference source and preventing data packet loss. The signal enhancement filter can accurately suppress electromagnetic noise and clutter, retaining only useful communication signals, thereby significantly improving the signal-to-noise ratio. The high-gain antenna is used to enhance the router's signal penetration and coverage, ensuring stable signal even in industrial settings with walls or obstacles.

[0017] The beneficial effects of this invention are as follows: 1. The research and development method and system of a low-power and high-stability router described in this invention utilize the hardware wake-up, serial port wake-up, or over-the-air (WOR) function of the module. In the chip sleep state, the chip consumes only a very low standby current. The radio frequency circuit is only started instantaneously when a specific signal is detected, so that the router can freely switch between high-load operation and low-power operation. 2. The research and development method and system for a low-power, high-stability router described in this invention are used to maintain extremely high signal penetration and anti-electromagnetic interference capabilities even under electromagnetic interference, harsh outdoor environments, sudden hardware failures, and network failures, ensuring stable and smooth network operation in harsh industrial, indoor, and outdoor environments.
