摘　　要：在煤炭开采行业内,井下的开采设备为了满足工矿自动化的需求也在快速的进行种类和数量的增加以及功能迭代。在目前阶段的井下综采控制系统内,诸多的设备需要组合为一套完整的系统,其主要包含井上的数据监控系统以及井下液压支架控制系统,井下液压支架控制系统内有成组的液压支架,另外每一组的液压支架又包含了标准型或网络型控制器,电源供给装置,各种智能传感设备,声光报警设备以及视频监控设备等,不同的设备采用的数据传输总线方案不同,有数字信号也有模拟量信号,这样要完成液压支架控制系统的数据采集,传输,计算整合,上传下发等就产生一定的困难。目前常用的单功能数据转换装置,其数据转换功能还是比较单一的,属于纯硬件转换,不能编程控制,这种转换器硬件电路部分复杂度高,功耗高。普通硬件转换器不仅仅功耗高还造成了设备布设的困难程度,为了解决上述问题本文重点论述了信号转换器的低功耗系统设计与应用,论述了信号转换器的低功耗设计方向,以及在液压支架控制系统中的信号转换功能及系统功能的分担,本文的信号转换器设计方案降低了硬件电路的复杂度和电路功耗,同时设计了可编程的低功耗动态控制算法,解决了液压支架控制系统中信号转换器高功耗的弊端,对进一步实现智能化低功耗开采具有深远意义。In the coal mining industry, in order to meet the needs of industrial and mining automation, the underground mining equipment is also rapidly increasing the variety and number and iterating the functions. In the current underground comprehensive mining control system, many equipment need to be combined into a complete system, which mainly includes the data monitoring system on the well and the underground hydraulic support control system. There are groups of hydraulic supports in the underground hydraulic support control system. In addition, each group of hydraulic supports includes standard or network controllers, power supply devices, and various intelligent sensing devices, Sound and light alarm equipment and video monitoring equipment, etc., different equipment adopt different data transmission bus schemes, including digital signals and analog signals. Therefore, it is difficult to complete data acquisition, transmission, calculation integration, upload and distribution of the hydraulic support control system. At present, it is a commonly used single function data conversion device, but its data conversion function is relatively single, which belongs to pure hardware conversion and cannot be programmed and controlled. This kind of converter has high complexity and high power consumption in hardware circuit. Ordinary hardware converters not only have high power consumption but also cause difficulties in equipment layout. In order to solve the above problems, this paper focuses on the design and application of low-power system of signal converters, discussing the low-power design direction of signal converter, the signal conversion function in the hydraulic support control system and the sharing of system functions. The signal converter design scheme in this paper reduces the complexity of hardware circuit and circuit power consumption. At the same time, a programmable low power dynamic control algorithm is designed to solve the problem of high power consumption of signal converter in hydraulic support control
