Description
技术领域technical field
本发明涉及的是一种用于检测技术领域的监控及维护系统，特别是一种气压沉箱无人化施工设备远程监控及维护系统。The invention relates to a monitoring and maintenance system used in the technical field of detection, in particular to a remote monitoring and maintenance system for unmanned construction equipment of a pneumatic caisson.
背景技术Background technique
无人化气压沉箱工法基本原理是向沉箱下部的作业室内输送与地下水压力相当的压缩空气以阻止地下水渗入作业室，即利用压缩空气抑制地下水。作业时无人进箱，所有作业全部使用遥控机械完成，作业时间不受限制，挖掘效率高，施工安全可靠，该种工法还具有施工占用空间小、结构强度大、对周围环境影响小等优点，所以该种工法极具发展前景。The basic principle of the unmanned air pressure caisson construction method is to send compressed air equivalent to the pressure of groundwater to the working room at the lower part of the caisson to prevent groundwater from seeping into the working room, that is, to use compressed air to suppress groundwater. No one enters the box during the operation, and all operations are completed by remote control machinery. The operation time is not limited, the excavation efficiency is high, and the construction is safe and reliable. This construction method also has the advantages of small construction space, high structural strength, and small impact on the surrounding environment. , so this kind of construction method has great development prospects.
但是，沉箱施工设备众多，沉箱内高温、高压、湿度很大，环境恶劣，加之人在地面对沉箱内的设备遥控操作，对地下工作室内的情况判断往往不够准确，容易发生操作失误，所以设备极易损坏，设备维护的任务相当繁重，一旦设备突然出现问题，轻则停工，重则威胁沉箱的安全，甚至还会造成事故，带来经济损失。所以，沉箱施工设备的性能监控和维护已成为沉箱施工技术的一个重要方面。但是目前的设备监控方式是在设备出现了问题时才报警，维护也是等到设备出现了故障之后，再进行处理，这种监控和维护方式不仅效率低，而且也容易因设备出现故障而引发安全问题。However, there are many construction equipment in the caisson, the high temperature, high pressure, high humidity inside the caisson, and the harsh environment. In addition, people operate the equipment in the caisson remotely on the ground, and the judgment of the situation in the underground working room is often not accurate enough, and operation errors are prone to occur. Therefore The equipment is easily damaged, and the task of equipment maintenance is quite heavy. Once a problem occurs suddenly in the equipment, it will stop the work at least, threaten the safety of the caisson at worst, and even cause accidents and economic losses. Therefore, the performance monitoring and maintenance of caisson construction equipment has become an important aspect of caisson construction technology. However, the current equipment monitoring method is to call the police when there is a problem with the equipment, and the maintenance is to wait until the equipment fails, and then deal with it. This monitoring and maintenance method is not only inefficient, but also easily causes safety problems due to equipment failure. .
中国发明专利(申请号200410017705.0)提出了一种基于网络的彩色喷绘机智能维护系统，该种方法仅适用于对喷绘机的监控，且该种方法操作复杂，也不适用于工作环境条件恶劣的场合。日本发明专利(专利号62133216)公布了一种沉箱挖掘机维护的发明，该发明侧重对维修工人的保护。该发明也没有对包括挖掘机在内的施工设备性能状态进行在线监测，起不到预防的效果，不能保证沉箱施工的安全。因此研究一种施工设备监控及智能维护系统，实现对施工设备的在线性能监控，并进行智能维护，对提高沉箱施工效率，保证沉箱施工安全设备，具有重要的现实意义。Chinese Invention Patent (Application No. 200410017705.0) proposes a network-based intelligent maintenance system for color inkjet printers. This method is only applicable to the monitoring of inkjet printers, and the method is complicated to operate, and it is not suitable for those with harsh working environments. occasion. Japanese invention patent (patent No. 62133216) has announced the invention that a kind of caisson excavator maintains, and this invention lays particular emphasis on the protection to maintenance workers. This invention also does not carry out on-line monitoring of the performance status of construction equipment including the excavator, and cannot achieve the effect of prevention, and cannot guarantee the safety of caisson construction. Therefore, it is of great practical significance to study a construction equipment monitoring and intelligent maintenance system to realize online performance monitoring and intelligent maintenance of construction equipment, which will improve the efficiency of caisson construction and ensure the safety equipment of caisson construction.
