目前国内在高层建筑中装设的消防泵遥控按钮多采用 SFAN—1型消防按钮盒(北京市第一低压电器厂生产),见图1。经过分析和试验,我们发现该按钮盒存在如下几个问题:1.不能及时关停消防泵当火灾发生时,消防(或值班)人员击碎消防按钮盒上的玻璃片,消防泵起动。但是,当火灾扑灭后,停泵却比较困难,因为 At present, domestic fire-fighting pump remote control buttons installed in high-rise buildings mostly use SFAN-1 fire button boxes (the first low-voltage electrical appliance factory in Beijing), as shown in Figure 1. After analysis and experiment, we found that the button box has the following problems: 1. Can’t shut down the fire pump in time.

However, when the fire is extinguished, stopping the pump is more difficult because
