随着四化建设的发展,石油化工、水利、水电及气象等部门均需要及时掌握生产过程的各种信息;例如水位、压力、流量、温度、风速、雨量…等等各种量的变化,为此必须进行随机采集以便进行综合分析、及时进行生产调度。由于这些信息往往量大面广,地点又相当分散,所以应用微处理和异频收发无线数传等先进技术来对上述信息进行采集和数据处理是较为理想的。 With the development of the four modernizations, petrochemicals, water conservancy, hydropower and meteorology departments need to keep abreast of various information in the production process; for example, changes in water level, pressure, flow, temperature, wind speed, rainfall, To do this, we must conduct random acquisition for comprehensive analysis and timely production scheduling. Due to the large amount of information and scattered locations, these advanced technologies such as micro-processing and inter-frequency transmission and reception of wireless data to collect and process the above information are ideal.
