【摘要】：伴随社会经济的发展,电梯使用量的急剧增长,电梯的事故也等比例地增加。现有针对电梯安全的监控系统,版本繁多系统老化,且系统架构分散不利集中统一管理,造成人工成本增加且管理效率低下,达不到预期的实时监控和及时处理的效果,无法满足电梯安全的需求。为能够有效监控电梯,本文设计了一个基于公共IP基础的统一架构,能够兼容各类版本系统,综合地把它们互联起来,将老电梯和新电梯都纳入监控的范围,实现统一的管理。新电梯内嵌了独立传感采集装置,采集电梯的运行参数和异常警报信息,并通过电梯内的内嵌装置的转换功能把信息转化为数字信号,依托预先布置好的光纤,有效完整地将信号传递到客服中心。由于老电梯的特殊硬件机理,产生信号格式和新系统所要求的信号格式完全不同,无法直接接入新系统。针对不同版本电梯的故障参数,需将其归到统一的信号参数定义标准中来供后台使用。就要进行信号转化处理,但在信号装换和传输过程中会出现外部干扰进而导致信号失真,到达处理中心时出现信号错误。本文利用接口技术转化信号,采用平衡驱动器和差分驱动器的组合的RS485接口,增强抗干扰,即抗噪音性,避免信号失真,保证尽量完整地转换为数字信号,既保证了信号质量又实现了系统的接入。为协调老旧电梯与新电梯监控系统的匹配,本文还使用了CTI技术,通过软件系统把它们顺利整合到同一管理平台,实现统一的界面管理。在统一硬件及转化接口的过程中,实现了硬件架构的统一,硬件设备可以实现综合统筹利用,节约了成本,提高了系统管理效率。CTI技术使用实现了综合的界面管理,便于迅速发现问题并处理问题,使得电梯运行的更加安全。
[Abstract]:With the development of social economy, elevator usage increases rapidly and elevator accidents increase in proportion. The existing monitoring system for elevator safety has many versions of the system aging, and the system framework is decentralized and unfavorable centralized management, resulting in increased labor costs and inefficient management, which can not achieve the expected real-time monitoring and timely processing effect. Unable to meet elevator safety requirements. In order to monitor elevators effectively, this paper designs a unified architecture based on common IP, which can be compatible with all kinds of version systems, interconnect them synthetically, bring old elevators and new elevators into the scope of monitoring, and realize unified management. The new elevator is equipped with an independent sensor collection device, which collects the operation parameters and abnormal alarm information of the elevator, and converts the information into digital signals through the conversion function of the embedded device in the elevator, relying on the pre-arranged optical fiber. Effectively and completely transmit the signal to the customer service center. Because of the special hardware mechanism of the old elevator, the signal format is completely different from that required by the new system, so it can not be directly connected to the new system. The fault parameters of different versions of elevator need to be classified into the unified signal parameter definition standard to be used in the background. Signal conversion is necessary, but external interference will occur in the process of signal replacement and transmission, which will lead to signal distortion and signal error when it reaches the processing center. In this paper, the interface technology is used to transform the signal, and the RS485 interface, which combines the balanced driver and differential driver, is used to enhance the anti-interference, that is, to resist noise, avoid the signal distortion, and ensure the complete conversion to digital signal as far as possible. It not only guarantees the signal quality but also realizes the access of the system. In order to coordinate the matching between the old elevator and the new elevator monitoring system, this paper also uses CTI technology, and integrates them into the same management platform through the software system to realize the unified interface management. In the process of unifying the hardware and transforming interface, the hardware structure is unified, the hardware equipment can be integrated and utilized as a whole, the cost is saved, and the system management efficiency is improved. CTI technology is used to realize the integrated interface management. Easy to quickly find problems and deal with problems, so that elevator operation is more secure.
