 背景技术
我国电梯行业历经数十年的发展，电梯已经成为人们生活中不可或缺的一部分，同时也是现代社会城镇化建设中必不可少的重要建筑设备之一。当前，我国是全球的电梯制造中心和最大的电梯市场，电梯产量、保有量、出口量逐年提升。随着电梯更新需求和旧楼加装电梯需求增加、房地产建设带来的刚性需求，预计未来电梯行业仍保持增长。
目前切断电机电源和制动器供电主要通过接触器来实现，其接触器串联在电机和制动器供电回路。特别是无机房和家用梯时，由于接触器频繁动作产生噪声，影响乘客乘梯体检，甚至会影响周边住户。同时由于接触器在断开时存在触点拉弧，导致接触器故障率高，甚至困人。为解决上述问题，可以采用低压电极控制器例如STO卡和SBC卡，但是由于低压STO卡和SBC卡需要低压供电，而厅门锁触点采用多层串联形式，层站较多引线较长，且长期使用后，会造成门锁触点的老化，阻抗变大，回路电流较小，导致电梯故障率较高。

本申请目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
 本发明的实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，本申请实施例中所有方向性指示（诸如上、下、左、右、前、后……）仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，在本申请中涉及“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当人认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
参照图1，图1为申请实施例提出的电梯控制器第一实施例的结构示意图。基于图1，提出本申请电梯控制器的第一实施例。

需要说明的是，电梯安全回路就是在电梯各安全部件都装有一个安全开关，把所有的安全开关串联，控制一只安全继电器。只有所有安全开关都在接通的情况下，安全继电器吸合，电梯才能得电运行。在电梯安全回路中的任意一个安全开关对应的部分存在故障时，该安全开关不会闭合，电梯也就无法运行。安全控制电路10是设置为对电压信号进行电压转换和整流的卡。在本实施例中，由于高压电源可以为电梯安全回路提供高压电信号，而低压电机控制电路30需要在低压条件下才能正常运行，因此安全控制电路10为将高压电信号转换为控制信号的电路。安全控制电路10可以设置为对电梯电机进行控制。

在本实施例中提出一种电梯控制器，该电梯控制器通过安全控制电路10、安全抱闸电路SBC和/或所述安全转矩关断电路STO；所述安全控制电路的输入端与电梯安全回路连接；所述安全控制电路的输出端与所述安全抱闸电路和/或所述安全转矩关断电路输入端连接。本实施例中通过高压电源为电梯安全回路供电，在电梯安全回路与低压电机控制电路之间设置安全控制电路为低压电机控制电路提供电源信号或控制信号，并根据电源信号或控制信号为低压电机提供低压电源，从而有效的解决了在采用低压电机控制电路时导致电梯故障率较高的问题。
