技术领域technical field

本发明涉及一种带臂锯无线遥控电气自动控制系统，尤其是通过PLC、触摸屏、无线遥控装置实现带臂锯的电气自动控制系统。The invention relates to a wireless remote control electrical automatic control system for a band arm saw, in particular to realizing the electrical automatic control system for a band arm saw through a PLC, a touch screen and a wireless remote control device.

背景技术Background technique

目前，国内尚未见使用，国外“带臂锯”主要采用按键、旋钮、文本等较常规的电气元件来实现“有线”操作控制的，通过常规开关、按钮和旋钮发出控制指令，交PLC控制中心分析、处理后发出执行指令，使执行单元动作——变频器驱动电机运转，在这个控制系统中由于采用的是常规电气元件，安装布线复杂，且控制台到机台的控制电缆芯线线数多，给安装带来不便同时这些元件在矿山特殊环境工作日久，易出现器件老化、触头氧化接触不良而带来的时有时无的“软故障”不易排查，同时还由于其显示文本的功能、库容不足而无法获得太多的设备信息，而影响故障分析、判断、检修等。At present, it has not been used in China. Foreign "band arm saws" mainly use more conventional electrical components such as buttons, knobs, and texts to realize "wired" operation control. After analysis and processing, an execution command is issued to make the execution unit act—the frequency converter drives the motor to run. In this control system, conventional electrical components are used, the installation and wiring are complicated, and the number of core wires of the control cable from the console to the machine Many, it brings inconvenience to the installation. At the same time, these components have been working in the special environment of the mine for a long time, and they are prone to device aging, contact oxidation and poor contact. Insufficient functions and storage capacity make it impossible to obtain too much equipment information, which affects failure analysis, judgment, maintenance, etc.

利用“带臂锯”进行石材切割，具有“链臂锯”所无法比拟的优势，它具有体积小、重量轻、锯切效率高且更加耐用适应性更强，制作工艺相对简单、成本更低廉等诸多优点，因此具有更大的发展潜力。The use of "band arm saw" for stone cutting has incomparable advantages over "chain arm saw". It has small size, light weight, high sawing efficiency, and is more durable and adaptable. The manufacturing process is relatively simple and the cost is lower. And many other advantages, so it has greater development potential.

采用触摸屏加无线遥控组合的电控系统具有操作方便、器件少、故障率低且界面直观、清晰、信息量充足便于提高设备检修效率。The electronic control system with touch screen and wireless remote control has the advantages of convenient operation, less components, low failure rate, intuitive and clear interface, and sufficient information to improve the efficiency of equipment maintenance.
