马卡遥爆系统的主从工作方式

Master and slave operation mode of Macha shooting system

在井炮施工中，马卡遥爆系统通过多台控制器（编码器）同步工作，可以进行多台地震仪器无线同步数据采集。马卡遥爆系统的工作方式是一种主从工作方式，是扩展数据采集系统道数、满足大三维地震勘探需要的一种有效手段。为了满足生产需要，一些地方对线路比较简单的SSS－200进行了功能改造。但与马卡遥爆系统相比，改造系统的紧凑性、可靠性都较差，只能作为一种临时性措施。而马卡遥爆系统的特点是电台传送距离较远，能达到15km，且功耗低，有利于炮点数据的传送，提高资料的优级品率。该系统的缺点是高压值较低，不利于多井组合施工；多台仪器同步采集时无故障联锁。文章介绍了系统主从工作方式的基本思想、计时的基本原理、设置和系统的优势与不足。

Using several Macha shooting system controllers in the exploration of the dynamic source, the instruments cansynchronously acquire seismic date by radio link between the several reconiers. This methed of Macha shooting system iscalled master-slave operation method which is effective for expanding the channels of recorder system to serve in therequirement of 3 - D seismic exploration. Although some people have simply improved the circuit of SSS - 200 to supplythe field production, but its compactness and reliability worse than Macha shooting system, so it is only used as atemporarily method. The another feature of the Macha shooting system is further radio transmission distance which can getto 15 kilometers and lower Power consumption. This advantage is useful for source point data transmission and quality ofacquiring field data. This system has a disadvantage the source uphole highvoltage survey threshold is low, it disadvantageto make group wells work and no fault interlock in several recorder acquiring simultaneously. This article introduces thebasic thinking of the master/slave operating method, its basic timing theory, settings, advantages and deficiency.
