Background
The single-phase electric meter is applied to active power electric measurement, is accurate in measurement, modularized and small in size, and can be easily installed in various terminal distribution boxes. The use scene mainly lies in the family expenses, commercial building, public infrastructure building, realizes the measurement, the statistics to different areas or different load electric energy consumptions in the building.
In order to standardize the power consumption and improve the protection to single-phase electric meter, most single-phase electric meters are installed in the ammeter case now, and present ammeter case includes transparent plastic ammeter case and the metal ammeter case that sprays paint, and wherein transparent plastic ammeter case has with low costs, looks over the number of degrees more directly perceived, and infrared ray data collection need not unpack advantages.
But the transparent plastic electric meter box also has the following defects: 1. single-phase ammeter is in operating condition for a long time, except installation, change maintenance etc. can not open the ammeter case under the normal condition, again because the ammeter case is in outdoors, generally concentrates on installing at walls such as corridor, passageway to mounted position is as high as possible, does not influence corridor, passageway and normally passes. After a period of time, the dust is piled up to the surface of ammeter case, influences looking over of ammeter and uses electric numerical value, data acquisition etc. in the place that the dust is more, can't see the inside condition of transparent plastics ammeter case even, more can't look over and use electric numerical value. 2. Because the ammeter case mounted position is very high, the people who looks over under this kind of condition are in looking up, even the clean dustless outside surface of transparent plastics ammeter case also can't normally look over, uses to have inconvenient part. 3. The portable transparent plastic electric meter box has multiple advantages, but is not superior to a metal electric meter box in service life and drop resistance. In the processes of transportation, installation and the like, the transparent plastic electric meter box is damaged due to accidental sliding.

s5: in S2, if the distance signal is not smaller than the set induction distance value, the voice signal is different from the first voice activation instruction, or the voice signal is different from the second voice activation instruction, the electric control board enables all the motors and the telescopic motors not to act.
