Description

一种桥梁远程监测系统 The Bridge Remote Monitoring System

技术领域 FIELD

本发明涉及自动化领域,特别涉及一种桥梁远程监测系统。 The present invention relates to the field of automation, and particularly relates to a system for remote monitoring of bridge.

背景技术 Background technique

现有技术桥梁监测方法主要包括以下三种方式:一、传统的监测方式。 Bridge prior art monitoring methods include the following three ways: First, the conventional monitoring methods.

现有技术中最传统的监测方式是采用人工进行数据的测量、记录和处理。 The most traditional prior art approach is to monitor artificial measurement, recording and processing data. 该监测方式测量速度慢,完成桥梁结构的一次采集数据耗时较长,难以保证各测点数据工作状态的一致性。 The monitoring methods slow measurement, a complete bridge configuration data acquisition time consuming, difficult to ensure consistency of data of each measuring point in the operating state. 例如8:00与10:00测的数据由于温度的影响造成桥梁结构工作状态不一致,再加上测点位置的不同,在处理时就较难消除温度的影响,数据的处理就变成比较复杂。 E.g. 8:00 and 10:00 the measured data due to the influence of the temperature caused by inconsistencies bridge structures operating state, plus the position of different points, it is difficult to eliminate the influence of temperature during the processing, the data processing becomes more complicated . 而且数据在测量、记录、处理过程中难免引入人为的误差甚至错误。 And the data in the measurement, recording, processing and even inevitable human error introduced errors. 由于桥梁地域分散,多处偏远地区,多为高空作业,桥梁施工和运营期间人工测量数据工作难度大。 Since the bridge geographical dispersion, many in remote areas, mostly high-altitude operations, manual measurement of large data difficult to work during bridge construction and operations.

二、利用GSM(泛欧数字蜂窝移动通信系统)网建立连接的桥梁远程监测方式。 Second, a bridge connected remote monitoring using GSM (Pan-European Digital Cellular Mobile Telecommunication System) network.

采用GSM连接的桥梁远程监测技术实施方式的工作过程为:传感器通过电缆线接到采集仪,采集仪采用现场RS485总线连接到电平转换单元上,电平转换单元采用RS232接口连接到GSM数据传输单元,GSM数据传输单元通过通信基站进入GSM网络与监测中心GSM数据传输单元建立点对点连接。 Bridge remote monitoring using GSM technology embodiment of the working process is connected: to the sensors through the cable collection instrument, logger uses the field bus is connected to the RS485 level conversion unit, the level conversion unit is connected to the RS232 interface using the GSM data transmission unit, GSM data transmission unit establishes an end-ligated into the GSM network with the monitoring center via the data transmission unit GSM communication base station. GSM数据传输单元通过RS232接口连接到监测中心计算机建立连接,实现桥梁的远程监测。 GSM data transmission unit connected through the RS232 interface to establish a connection to the monitoring center computer, remote monitoring bridges.

采用GSM连接的桥梁远程监测方式是利用GSM网络的电路交换的话音业务建立点对点的数据建立连接,通过数据中心计算机分别控制桥上各采集仪采集数据。 Using the remote monitoring mode is to establish a bridge connection GSM GSM network using circuit-switched voice service data point to establish a connection, the control device gathers various data center computer acquired by each bridge. 此种方法的数据中心与各处采集设备的链接是采用点对点的方式,数据中心同一套设备在同一时间只能采集一座桥梁或一个采集仪相连接的传感器数据。 This method of data centers and the entire collection of linked devices in point-of use, the same set of data center equipment can collect sensor data acquisition instrument or a bridge connected at the same time. 而且对总线上的设备控制也是点对点的控制方式,故数据采集的速度慢、操作繁琐。 Further control of the control device on the bus is point to point, so that data collection is slow, cumbersome operation. 数据传输方法是基于移动通信2.0G技术,数据中心计算机必须配备专用的数据传输模块和移动电话卡,使用极不方便。 Data transmission method is based on 2.0G mobile communication technology, the data center computer must be equipped with a dedicated data transmission module and the mobile phone cards, very inconvenient to use. 数据传输速度慢、费用高、建立大型监控网比较困难。 Data transmission is slow, expensive, difficult to establish large-scale monitoring network.

三、利用光缆建立连接的桥梁远程监测方式。 Third, the use of fiber optic cable connected to establish remote monitoring of bridges.

利用光缆建立连接的桥梁远程监测技术实施方式的工作过程为:传感器通过电缆线接到采集仪,采集仪采用现场RS485总线连接到控制终端机上,控制终端机连接到光电转换器接入远程光缆网络,再通过监测中心光电转换器与监测中心计算机建立连接,实现桥梁的远程监测。 Optical cable remote monitoring technology to build a bridge of the embodiment connected to the working procedure: a sensor to the logger via cable, RS485 logger uses the field bus connected to the control terminal, a control terminal connected to the photoelectric conversion remote access cable network and then establish a connection via the photoelectric converter monitoring center and monitoring center computer, remote monitoring of bridges.

利用光缆建立连接的桥梁远程监测方式是利用专用光缆或租用电信公用光缆建立数据连接,监测中心计算机控制采集设备完成数据采集或通过设置控制终端机实现数据的自动采集。 Establishing a remote monitoring optical cable connected to the cable bridge utilizing a dedicated or leased telecommunication cable common data connection, monitoring center computer-controlled data acquisition or acquisition terminal equipment for data collection by the automatic setting control. 此种方法的缺点是成本高、维护难度大、监测中心比较固定,组建大型监控网比较困难。 The disadvantage of this method is the high cost, difficult maintenance, monitoring centers relatively fixed, the formation of large-scale monitoring network more difficult.

因此,如何在桥梁分布零散的情况下组建大型监控网,实现桥梁的远程监测,是目前需要解决的问题。 Therefore, how to build bridges scattered distribution in the case of large-scale network monitoring, remote monitoring of bridges, is the need to address the problem.

线程池不是简单的多线程。 The thread pool is not a simple multi-threaded. 在一个程序中,并不是线程越多响应越快。 In a program, the more the faster the response is not thread. 基本上代码结构合理,线程数目和CPU个数相等就可以。 Substantially reasonable code structure, and the number of threads can be equal to the number of CPU. 如果有支持超线程的CPU,则应相应增加线程。 If the CPU supports hyperthreading, threads should be increased accordingly.

多线程技术主要解决处理器单元内多个线程执行的问题,它可以显著减少处理器单元的闲置时间,增加处理器单元的吞吐能力。 Multi-threading technology to solve major problems multiple threads of execution within the processor unit, it can significantly reduce the idle time of the processor unit, increasing the throughput capacity of the processor unit. 但如果对多线程应用不当,会增加对单个任务的处理时间。 However, if the improper application of multi-threaded, it will increase the processing time for a single task.

对于一般的应用,考虑到需要及时的响应用户界面,可以把交互和调度等工作放在主线程单元里面,此线程占用CPU开销极小,可以忽略。 For general applications, taking into account the need for a timely response to the user interface, and may interact with the scheduler work inside the unit on the main thread, this thread occupies minimal CPU overhead, it can be ignored. 另开的任务线程数目则最好符合上面的原则。 The number of threads open another task is best in line with the above principles.

优选方式,调度程序在所有工作线程都繁忙时候再创建新线程,达到限定数目后不再创建新线程,转而把任务加入待处理队列。 Preferred embodiment, after creating a new thread scheduler in all worker threads when busy, not reached the defined number to create new threads, instead be added to the task processing queue.

任务线程设计成一个循环,除非主线程单元通知,否则永不中止。 Task thread designed as a loop, the main thread unit unless notified otherwise never aborted. 每一次循环首先检查任务队列,如果发现有待处理任务,则处理,并标记此任务为“正在处理”。 Each time through the loop first checks the task queue, if you find the task to be processed, the processing, and mark this task as "Processing." 处理完成后从队列中删除此任务。 After processing is complete to delete the job from the queue.

线程池单元包括:线程池管理器(Thread Pool Manager):用于创建并管理线程池。 Thread pool unit includes: a thread pool manager (Thread Pool Manager): used to create and manage the thread pool.

辅线程子单元即工作线程单元(Work Thread):线程池单元中的辅线程。 I.e., the secondary thread subunit worker unit (Work Thread): secondary threads in the thread pool unit.

任务接口(Task):每个任务必须实现的接口,以供工作线程调度任务的执行。 Task Interface (Task): Each task must implement in order to work for thread scheduling task execution.

任务队列:用于存放没有处理的任务。 Task Queue: used to store the task is not processed.
