随着社会的发展,各种管网(热、水、电、油、煤气等)越来越多,管网测点数据的采集和及时传输是管网稳定、可靠运行的保证,要求计算机管网监测系统必须能够在较低费用的前提下提供及时、准确的信息。然而,在使用的过程中,传统有线、无线的管网监测系统的不足之处逐渐凸现出来。采用电话线传输数据,不能保证实时性;采用无线电台,解决误码率和波特率的矛盾尤其抗干扰是一个令人头疼的问题;采用专线电路,不可能对所有大面积分散的数据采集子站进行专线铺设,更不能承担高昂的运行费用。针对这些问题,采用先进成熟的DTU模块为远程数传模 With the development of society, all kinds of pipe networks (heat, water, electricity, oil, gas, etc.) are getting more and more. The collection and timely transmission of pipe network data is the guarantee of stable and reliable pipe network. Network monitoring systems must be able to provide timely and accurate information at a lower cost. However, the shortcomings of the traditional wired and wireless pipe network monitoring system gradually emerge during the process of using. The use of telephone lines to transmit data, can not guarantee real-time; using radio to solve the bit error rate and baud rate of the contradiction, especially anti-jamming is a troublesome problem; using a dedicated circuit, it is impossible for all large-scale distributed data acquisition Sub-station green laying, but can not afford the high operating costs. In response to these problems, the use of advanced and mature DTU module for the remote digital mode
