Method and apparatus for acquiring data

摘要

The invention relates to a method and data collection devices arranged in a decentralized data collection terminal, designed with at least one data collection terminal (PGxy) and at least one intermediate terminal (SGX). With at least one terminal of the data collection (PGxy), the data is collected and transmitted via the first communication path (4) to at least one intermediate (SGX). The data collection terminal (PGxy) transfers data at intervals determined in advance and during the time window determined in advance. The at least one data collection terminal (PGxy) is automatically assigned to the at least one intermediate terminal (SGX). The at least one intermediate terminal (SGX) is switched to receive data only during the time window determined in advance and after an interval determined in advance of the data collection terminal (PGxy), the associated intermediate (SGX). The device for carrying out this process is governed more intermediate terminals (SG1. .. n), among which there are two-sided second communication path (3), and to this intermediate terminals (SG1. .. n) for building the first network (N1) with associated means assigns a unique network address and a unique terminal address.
