Controlling distribution of gravel, sand, salt etc. on roads in winter - dispensing in controlled pattern by microprocessor unit

摘要

A spreading unit for the distribution of sand and salt onto a road surface to prevent ice build-up in write has a container (2) with a microprocessor module (5) controlling a variable output stage (4). A control cable (5) is coupled to a panel (6) with an on-board computer (7) for setting the operating point. Data can be obtained and entered into a memory chip (9) which can be removed and entered into a reader for transferring the data to a stationary compute (11). Processed data can be produced as printed information. ADVANTAGE - Can be fully automatic according to stored program.
