Description
技术领域Technical Field
本发明涉及智慧燃气技术领域,尤其涉及一种自供电智能调压系统及其调压方法以及管道网络区域通讯系统。The present invention relates to the field of smart gas technology, and in particular to a self-powered intelligent pressure regulating system and a pressure regulating method thereof, and a pipeline network area communication system.
背景技术Background technique
燃气从上游输送到各用户需经过各压力等级调压后才能供用户使用,燃气压力的调整设备统称为调压器,各城市分别建设门站接收长输管线输送的天然气,压力为高压,由高中压调压器降低为中压后,输送到市区,再由调压器将中压降低为低压供用户使用,因各用户使用的压力要求不同,所以有不同型号的调压器,也就是不同压力等级和出口流量的调压器。Gas is transported from upstream to each user after being regulated at various pressure levels before it can be used by the user. The gas pressure adjustment equipment is collectively called a pressure regulator. Each city builds a gate station to receive natural gas transported by a long-distance pipeline. The pressure is high pressure, which is reduced to medium pressure by high and medium pressure regulators and then transported to the urban area. The pressure regulator then reduces the medium pressure to low pressure for users. Because the pressure requirements of each user are different, there are different types of pressure regulators, that is, pressure regulators with different pressure levels and outlet flow rates.
长期以来,各型号的调压设备型号全面,性能也较稳定,运行状况也较安全,但因各类原因发生的事故也时有发生,一是由于调压设备因长期未保养,零部件老化造成的故障;二是由于管线遭到破坏(挖掘机开挖时将管道挖断)时调压器发生故障,三是由于调压器是气压与机械联动,本身设计的功能不具备智能和远程控制功能,由于调压器正常运行需要有一定进口压力才能启动运行,当管道被挖断时,燃气大量泄漏,压力急聚下降,调压设备失灵不能自动关阀造成的事故;四是新建管道与已建管道对接过程中操作不当造成调压器失灵而发生的故障;五是维修或安装不正确造成的故障;六是各调压器、流量计、阀门、标志桩的无线通讯没有建立一个完整的通讯系统,单独建立费用高,基于上述的原因,研发智能调压设备及系统来弥补调压器本身的功能不足,利用调压柜建立区域通讯中心,同时解决了供电和集中通讯的问题,大幅降低通讯费用,为建设智慧燃气奠定了基础,也符合本质安全管理的需求。For a long time, various types of pressure regulating equipment have been available, with relatively stable performance and safe operation. However, accidents due to various reasons also occur from time to time. One is that the pressure regulating equipment fails due to long-term lack of maintenance and aging of parts; the second is that the pressure regulator fails when the pipeline is damaged (the pipeline is broken by the excavator); the third is that the pressure regulator is linked to air pressure and machinery, and its own design function does not have intelligent and remote control functions. Since the normal operation of the pressure regulator requires a certain inlet pressure to start running, when the pipeline is broken, a large amount of gas leaks, the pressure drops sharply, and the pressure regulating equipment fails and cannot automatically The first is the accident caused by the moving closing valve; the second is the failure of the pressure regulator caused by improper operation during the connection between the new pipeline and the existing pipeline; the third is the failure caused by incorrect maintenance or installation; the fourth is the failure of the pressure regulator caused by improper operation during the connection between the new pipeline and the existing pipeline; the fifth is the failure caused by improper maintenance or installation; the sixth is that the wireless communication of each pressure regulator, flow meter, valve, and marker has not established a complete communication system, and the cost of establishing a separate system is high. Based on the above reasons, intelligent pressure regulating equipment and systems are developed to make up for the insufficient functions of the pressure regulator itself, and a regional communication center is established using the pressure regulating cabinet. At the same time, the problems of power supply and centralized communication are solved, which greatly reduces the communication costs, lays the foundation for the construction of smart gas, and meets the needs of inherent safety management.
