  8. In paragraph 1, The above control unit is, Collecting environmental data in sections corresponding to the above plurality of location data, and It is configured to provide a warning notification if environmental data deviates from preset thresholds, and The above environmental data includes at least one of the temperature, humidity, illuminance, and impact amount of the cargo, on a server.
  9. In paragraph 1, The above control unit is, A server configured to provide a notification including the deviation information when it is determined that the above cargo has deviated from the delivery route.
  10. As a method of providing delivery route information performed by a server, A step of collecting multiple location data based on base stations in accordance with cargo delivery; A step of generating position correction data by correcting the above position data; and A method comprising the step of providing delivery route information based on the above-mentioned location correction data.

Description

Method for Cargo Location Correction Based on Base Stations and Cargo Monitoring System Various embodiments of the present invention relate to a system for more efficiently monitoring the temperature and location of sensitive cargo, such as pharmaceuticals. Due to recent advancements in the international logistics and delivery industries, the safe transportation of sensitive cargo—particularly temperature and humidity-sensitive products such as pharmaceuticals—is becoming increasingly important. These pharmaceuticals must maintain constant temperature and humidity levels during transport, and continuous environmental monitoring is required to prevent quality degradation caused by temperature fluctuations. Consequently, logistics companies are adopting systems that monitor cargo location and environmental data in real time to manage product conditions based on this information. Generally, the Global Positioning System (GPS) is widely used for tracking cargo locations. While GPS can provide relatively accurate location information, it suffers from high battery consumption and signal weakness indoors or in densely populated high-rise areas. Particularly during long-distance transportation, there is a growing trend to utilize mobile communication base station-based location tracking systems instead of GPS to reduce battery usage. Location-Based Services (LBS) estimate the location of cargo using the signal strength of base stations instead of GPS. However, base station signal strength can fluctuate depending on environmental factors, which may lead to errors in location information. For example, if cargo remains in a congested area or travels a short distance, fluctuations in signal strength can cause location information to jump or be recorded as congested data.
