家用电器指的是放置在家庭中能够对人们生活提供帮助的设备，其按照功能和用途可以分为制冷电器(如冰箱、冷饮机等)、空调电器(如空调器、空气去湿器等)、清洁电器(如洗衣机、干衣机、吸尘器等)、厨房电器(如电灶、微波炉、电烤箱等)、电暖器具(如电热毯、电热器等)、整容保健器具(如电动剃须刀、电吹风等)、声像电器(如电视机、电脑、收音机等)以及其他电器(如烟火报警器、电铃等)，通过上述的家用电器，可以为人们创造更为舒适优美、更有利于身心健康的生活和工作环境，并提供丰富多彩的文化娱乐条件。
家庭用电的功率和电流都具有其上限，例如，家庭一般的供电电流限定为30A，一些新的住宅区的家庭的供电电流可以达到35A，而用电的总功率一般限定在6000W内为宜，这就使得家庭内的家用电器不能同时使用。尤其是功率较大的几台家用电器，在使用的时候需要错峰运行，避免家庭的用电功率和/或用电电流超过额定值，出现跳闸断电的情况，给用户带来诸多不便(尤其是在晚上)。
为此，现有技术通常通过检测各个家用电器的总功率/总电流的数值，并在该数值达到家庭的用电功率/用电电流的额定数值时，关闭一台或多台家用电器。

下面以三台相同的洗衣机为例，来对本发明的控制方法进行详细说明。
洗衣机的运行周期包括四个时间段，第一个时间段(3min)为进水，对应第一用电功率a；第二个时间段(15min)为洗涤，对应第二用电功率b；第三个时间段(10min)为漂洗，对应第三用电功率c；第四个时间段(5min)为脱水对应第四用电功率d。其中，a＜b＜c＜d。
处理模块22获取第一台洗衣机当前的运行时间为1min，第二台洗衣机当前的运行时间为10min，第三台洗衣机当前的运行时间为20min。
其中，第一台洗衣机对应到洗衣机的运行周期内的时间为第一时间段，洗衣机当前时刻的用电功率为第一用电功率a。其在未来2min内的用电功率都是第一用电功率a，在未来2-17min内的用电功率都是第二用电功率b，在未来17-27min内的用电功率都是第三用电功率c，在未来27-32min内的用电功率都是第四用电功率d。
其中，第二台洗衣机对应到洗衣机的运行周期内的时间为第二时间段，洗衣机当前时刻的用电功率为第二用电功率b。其在未来10min内的用电功率都是第二用电功率b，在未来10-20min内的用电功率都是第三用电功率c，在未来20-25min内的用电功率都是第四用电功率d。
其中，第三台洗衣机对应到洗衣机的运行周期内的时间为第四时间段，洗衣机当前时刻的用电功率为第四用电功率d，在未来3min内的用电功率都是第四用电功率d。
为了便于理解，假定a＝1，b＝2，c＝3，d＝4。则三台洗衣机在未来将要产生的总用电功率如下：
在未来2min内，总用电功率＝a+b+d＝7；
在未来2-3min内，总用电功率＝2b+d＝8；
在未来3-10min内，总用电功率＝2b＝4；
在未来10-17min内，总用电功率＝b+c＝5；
在未来17-20min内，总用电功率＝2c＝6；
在未来20-25min内，总用电功率＝c+d＝7；
在未来25-27min内，总用电功率＝c＝3；
在未来27-32min内，总用电功率＝d＝4。
假设家庭用电的额定功率是8，则三台洗衣机在继续运行2min之后，必须暂停或关闭一台。优选地，暂停第一台洗衣机，待第三台洗衣机运行结束之后，再使第一台洗衣机继续运行。
通过文描述的内容，本领域技术人员能够理解的是，本发明的控制系统2和/或控制方法能够提前预测所有家用电器1的总用电功率是否可以达到家庭用电的额定功率，并在达到之前及时关闭或暂停一台或多台家用电器1，避免了家庭用电的额定功率过大时出现跳闸的情况。
在本发明另一个可行的技术方案中，与上述优选实施方案不同的是，本领域技术人员可以根据需要，不在存储模块23中存储每一台家用电器1的用电功率，而在存储模块23中存储每一台家用电器1的运行参数，然后使处理模块22通过所述运行参数计算得出每一台家用电器1的用电功率。或者，本领域技术人员还可以根据需要，使处理模块22通过通信模块21获取每一台家用电器1的用电功率和/或运行参数。其中，所述运行参数至少包括家用电器1的输入电流和输入电压。
进一步，在本发明另一个可行的技术方案中，与上述优选实施方案不同的是，本领域技术人员可以根据需要，以用电电流替换用电功率作为计算依据，来判定家庭用电是否将要超载。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
