实施例 3
一种可分组级联的移动升降系统的控制方法,包括以下步骤:
A.              分组设置:在一种可分组级联的移动升降系统出厂时进行分组设置,并将每一分组中的升降设备1进行编号;
B. 通过每一分组中的主控制柱进行模式设置:当设置为单柱模式时,本升降设备1的按键只能控制本升降设备1中立柱3的升降;当设置为本组模式时,任何升降设备1的按键都可以控制本升降设备1中立柱3的升降;当设置为级联模式时,任何级联分组中升降设备1的按键都可以控制所有分组中的立柱3进行同步升降;
C. 不同模式下,总控制柱的确定:单柱模式时,总控制柱就是这个单一的升降设备1;本组模式时,总控制柱为本分组的主控制柱;级联模式时,总控制柱为第1组的主控制柱;
D.              动作机构的实现:各升降设备1之间同步的信号为位置信号,总控制柱形成目前各立柱3的最高高度和最低高度,分发到各升降设备1,各升降设备1根据本升降设备1中立柱3的最高高度、最低高度以及目前工作状态自行控制本立柱3的动作机构,以达到与整体同步;
目前工作状态包括上升、下降、落锁、慢速下降、设置零点、组网;
当目前工作状态为上升时,采用与目前最低高度的立柱3比较的方法:当本立柱3的高度大于最低高度2cm时,通过打开泄压阀降低上升速度;当本立柱3的高度大于最低高度4cm时,停止上升,等待其他立柱3;当本立柱3的高度大于最低高度1cm时,关闭泄压阀,进行上升;
当目前工作状态为下降时,采用与目前最高高度的立柱3比较的方法:当本立柱3的高度低于最高高度2cm时,通过关闭泄压阀降低下降速度,当本立柱3的高度大于最高高度4cm时,停止下降,等待其他立柱3;当本立柱3的高度低于最大高度1cm时,打开泄压阀,进行下降;
当目前工作状态为落锁和慢速下降时,参考最高高度和最低高度实现同步,落锁和慢速下降使用小泄压阀,速度较慢;
当目前工作状态为设置零点时,采用位移传感器读取本立柱3当前的读数,如果读数与保存的零点不同,则将当前的读数保存为新的零点,直至对出设置零点的工作状态;
当目前工作状态为组网时,由主控制柱检测CAN网络在系统设置中设置的升降设备1是否都存在,且没有重复,组网完成进入工作状态。
具体来说,当模式设置为单柱模式时,分组内各升降设备1可以进行独立的上升、下降、落锁操作,不受分组内主控制柱的管理;当模式设置为本组模式时,分组中的副柱负责获取本副柱的高度和按键情况,传递到本分组的主控制柱,主控制柱负责计算本分组的最高高度和最低高度,并根据按键情况确定本分组的工作状态,并分发到各个副柱,各个副柱根据主控制柱分发的最高高度、最低高度以及工作状态,自行控制本升降设备1的动作机构,以达到与整体同步运行,不发生超差;当模式设置为级联模式时,使用多个分组,每个分组设置一个分组序号,通过另外的通讯通道将需要级联的分组的主控制柱另行建立一个通讯网络,使得各分组的主控制柱可以互相通讯;各分组的主控制柱将本分组的最高高度、最低高度、按键信息发送到总控制柱,总控制柱负责计算所有分组的最高高度、最低高度,并分发到各分组的主控制柱,各分组的主控制柱再将信息分发组内的各副柱,同时总控制柱根据各组的按键情况,确定工作状态,分发到各分组的主控制柱,各分组主控制柱再分发到各副柱;最后所有副柱根据最高高度、最低高度以及工作状态,自行控制本升降设备1的动作机构,以达到与整体同步运行,不发生超差。其中每个分组的按键根据不同的工作模式,作用的范围不同,没有目标位置,根据按键进行操作,按键松手则停止工作,当上升时达到最高高度自动停止,下降时降到最低高度则自动通停止;不同升降设备1如果有冲突的按键,装置将停止工作。
