Card plug-in type power saving controller for hotel standard guest room

Abstract

The invention relates to a card plug-in type power saving controller for a hotel standard guest room, which is arranged in a hotel standard guest room and uses a card plug-in and power obtain control switch. When guests leave a room, the power obtain control switch delays for 15-30 seconds and then automatically switches off a mains supply in the guest room, thereby not only saving the electric charge, but also prolonging the service life of electrical appliances, and it is important that the electric use safety of the guest room is improved. In the card plug-in and power obtain control switches in the market at present, almost all power switching elements adopt an electromagnetic relay structure which congenitally has the defect that contacts are easy to ablate and strike fire, and contact ablations can be continuously accumulated to increase the resistance so as to further aggravate the contact fire striking, and finally cause power saving failures and become a fire hazard. On the basis of retaining the power saving conception of the traditional card plug-in and power obtain control switches, the power switching element of the power saving controller adopts core elements such as a photoelectrical coupling zero crossing SCR ( Silicon Controlled Rectifier) driver, a two-way SCR, and the like, overcomes the defects of easy contact ablation, fire striking, and the like of the electromagnetic relay, achieves the purpose of using the two-way SCR to carry out non-contact and high-power switching and effectively eliminates fire hazards of the hotel guest rooms.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to a "plug-in card type" power-saving controller for a standard guest room in a hotel. Background technique [0002] The plug-in card power switch (power-saving controller) is specially designed for the energy saving and safety of hotels and hotels. After the hotel installs the plug-in power switch, when the guest checks in, the guest inserts the door card (opening card) into the guest room The power switch on the side of the inner door, the mains in the room is connected, and various electrical equipment (lighting, TV, air conditioner, etc.) in the room can be used; when the guest leaves the room, the guest takes the power card (guest You must pull out the card before you can leave the room, because the guest needs to use this card to open the door when returning to the room), and the power switch after inserting the card is generally delayed for 15 to 30 seconds and then automat...

AI Technical Summary

Problems solved by technology

[0007] At present, almost all the mains power switching components used in the popular plug-in card power-taking control switches in the market are electromagnetic relay structures, because electromagnetic relays have inherent contacts that are easy to be ignited and ablated, and the ablation of relay contacts will continue to accumulate And increase the on-resistance, and then continuously aggravate the sparking of the contacts, which may lead to the failure of power saving, but become a fire hazard in the guest room
