Static and dynamic program-controlled strain test system

The invention proposes a static and dynamic program-controlled strain test system for the defects that the strain test system in the prior art has the problems of low sampling precision, inflexible bridging form, short transmission distance, single communication mode, and inflexible human interaction mode. A 24-bit A/D chip is adopted, thereby greatly improving the sampling precision; arbitrary bridging form is carried out on each measuring point, thereby improving the flexibility of bridging form; internet interfaces, USB, RS485, WIFI, ZIGBEE and other communication methods are integrated, thereby greatly improving the communication capability of the system; a touch-screen liquid crystal color screen is adopted for the human-machine interface, users can input parameters in the liquid crystal color screen and observe the sampling information. 现有技术中的应变测试系统存在采样精度不高、组桥形式不够灵活、传输距离短、通讯方式单、人界交互方式不够灵活的问题。鉴于现有技术的缺陷，本发明创造提出种动静态程控应变测试系统，采用了24位的A/D芯片，极大程度的提高的采样的精度，每测点任意组桥，提高了组桥形式的灵活性，集成了网口，USB，RS485，WIFI，ZIGBEE等通讯方式，大大提
