It is connected.
It is upper electronic when the upper detection sensor 2 or lower detection sensor 3 detect the electric card of card non-corresponding of insertion
Gate 3 and lower electric gate valve 4 act, conversely, when the upper detection sensor 2 or lower detection sensor 3 detect the card of insertion
When being corresponding electric card, give one signal of the master controller, the master controller can control the upper electric gate valve 3 and under
Electric gate valve 4 act, open card inserting mouth into card channel, realize into card.
The realization of contact CIS imaging sensors may be used in the upper detection sensor 2 or lower detection sensor 3, described
The upper drive mechanism 31 and lower drive mechanism 41 of the upper electric gate valve and lower electric gate valve are driving motor.
The utility model can make single-phase electric energy meter by above technical scheme, and can have prevents external illegal card insertion
Enter destruction of the card inserting mouth to card inserting mouth, improves the security performance of electric energy meter.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
