Description

Technical Field

[0001] This utility model belongs to the field of road surface temperature detection technology, and specifically relates to a sensor for road surface temperature detection. Background Technology

[0002] Ground Temperature Remote Intelligent Monitoring Terminal: The device adopts NB-IoT wireless remote communication technology, features a low-power design, and has a built-in battery pack, eliminating the need for an external power supply. The device's intelligent main controller communicates with the cloud platform, and the downstream sensors are connected in two paths: one to a water level monitor and the other to a ground temperature sensor. The device is installed on-site using selected poles. After installation, it collects data at a set frequency and transmits the accurate information monitored on-site to the smart meteorological cloud platform in real time. Conventional road surface detection cannot achieve high-frequency monitoring, making it difficult for the equipment to achieve more efficient detection during subsequent processing. This results in equipment that is highly susceptible to damage, has poor data acquisition and transmission quality, and large measurement errors. It is difficult to achieve the equipment's functional requirements of integrated acquisition, control, and transmission, support for remote parameter setting (including thresholds, upload frequency, static error compensation value, GPS data, target server IP address, etc.), low power consumption, adaptability to various power supply methods, and saving power supply costs.
