Abstract

A refrigerator and air-conditioner thunder protection control device is provided. The device is innovated based on the ZigBee wireless one-chip microcomputer technology, the fingerprint identification technology and the relay control technology, and can be used for effectively and reliably preventing thousands of refrigerators and air-conditioners from being damaged by thunder when only one personnel needs to work. When large thunder occurs, an operator on duty can emit a wireless instruction for closing power supplies of refrigerators and air-conditioners through a coordinator node arranged inside a district duty room, the thunder protection function can be realized, and the operator on duty can emit a wireless instruction for opening the power supplies of the refrigerators and the air-conditioners through the coordinator node after the thunder, fingerprint information needs to be confirmed to avoid maloperaiton of other personnel before the instruction is sent; and masters can also set the power supplies of the refrigerators and the air-conditioners on a controlled or non-controlled state through a switch of a terminal control node.

Description

The lightning protected control device of a kind of refrigerator and air-conditioning

Technical field

The utility model relates to ZigBee wireless singlechip technology, fingerprint identification technology, Control technology, especially a kind of refrigerator and the lightning protected control device of air-conditioning.

Background technology

The accident that electric equipment occurred between the guarantee period be data show more than sixty percent because power quality is not good enough and the surge injury causes.And thunder and lightning causes the topmost reason of surge exactly, in general, after thunder and lightning occurs, can produce larger surge in moment, thereby destroys the electronic component of household electrical appliances inside by power lead etc.The most direct evidence is exactly when thundering, and snow and larger lines appear in televisor, the picture quality variation, because surge causes, the expensive family thunders and lightnings such as refrigerator, air-conditioning cause especially suffers heavy losses.

CC2530 is a real SOC (system on a chip) (SoC) solution for 2.4-GHz IEEE 802.15.4, ZigBee and RF4CE application.It can set up powerful network node with low-down total material cost.CC2530 combines the premium properties of leading RF transceiver, the enhancement mode 8051CPU of industrywide standard, In-System Programmable flash memory, 8-KB RAM and many other powerful functions.

Fingerprint identification technology is present the most ripe and low-cost biometrics identification technology, and along with the progress of science and technology, fingerprint identification technology has begun slowly to enter in the embedded control system, and is multiplex in the application higher to security requirement.

Summary of the invention

The purpose of this utility model is to provide a kind of refrigerator and the lightning protected control device of air-conditioning, when large thunderstorm hour occurring, the operator on duty sends closing refrigerator and air-conditioning power supply wireless instructions by the coordinator node that is placed in the duty room of residential quarter, realize lightning protected function, thunder and lightning later operator on duty sends connection refrigerator and air-conditioning power supply wireless instructions by coordinator node; Before sending instruction, need carry out finger print information and confirm for preventing other staff's maloperation; Refrigerator and air conditioner power source that owner also can arrange by the switch of terminal control node oneself are in controlled and uncontrolled state.

The technical scheme that its technical matters that solves the utility model adopts is: the utility model take the wireless singlechip CC2530 that follows Zigbee protocol as core in conjunction with fingerprint identification technology, the Control technology designs, by coordinator node, routing node and terminal control node three parts form, it is characterized in that: coordinator node is by the CC2530 wireless singlechip, FPC1011C semiconductor fingerprint identification module, KCD1-101 two foot controls, 5G3SD light emitting diode indicator consists of, routing node carries out data relay by the CC2530 wireless singlechip, and the terminal control node is by the CC2530 wireless singlechip, KCD1-101 two foot controls, 8550 triode drivers, grand JQX-14FW relay switch consists of.

The beneficial effects of the utility model are: create artificial refrigerator and an air-conditioning of doing the hundreds and thousands of families of protection and avoid effectively reliably thunder and lightning to damage.The wireless singlechip CC2530 that Zigbee protocol is followed in employing carries out the wireless networking design, and is flexible for installation, convenient, adopts fingerprint identification technology to guarantee that operation is reliable.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is the theory structure block diagram of utility model.

Embodiment

Be comprised of coordinator node, routing node and terminal control node three parts referring to Fig. 1 the utility model, the terminal control node is placed in supply socket place of refrigerator and air-conditioning, controls the logical and disconnected of refrigerator and air conditioner power source line by relay switch; Routing node is placed on the ceiling or wall of corridor flexibly; Coordinator node is placed in the duty room of residential quarter; All nodes are all transplanted the ZigBee2007 wireless communication protocol stack, carry out radio communication.

Coordinator node is made of CC2530 wireless singlechip, FPC1011C semiconductor fingerprint identification module, KCD1-101 two foot controls, 5G3SD light emitting diode indicator.Design take CC2530 as core, FPC1011C semiconductor fingerprint identification module adopts SPI interface and PERCOM peripheral communication, the design is arranged to the SO mouth with the P0_1 of CC2530, P0_2 is arranged to the SI mouth, P0_3 is arranged to the SCK mouth and FPC1011C communicates, and CC2530 is arranged to host mode, and FPC1011C is arranged to slave mode, clock signal SCK is provided by CC2530, and gathering finger print information image size is 200 * 152 pixels.The registration finger print information is by gathering fingerprint characteristic and storing fingerprint characteristic information into fingerprint base, the design's fingerprint base adopts the FLASH space of CC2530 to carry out access, fingerprint to registration is given corresponding ID number, to make things convenient for the operator on duty to manage, one piece of fingerprint of every typing, according to the FLASH address of its ID number modification CC2530, the registration fingerprint function realizes P0_4 mouth ground connection by wire, passes through 3 alert of 5G3SD LED flash and operate successfully after the success of registration finger print information.The P0_5 pin of KCD1-101 two foot controls one termination CC2530, other end ground connection, the P0_5 pin of CC2530 connects the pull-up resistor of 1K ohm simultaneously, P0_5 is high level when KCD1-101 disconnects, P0_5 is low level when KCD1-101 is closed, this arranges P0_5 is that low level represents that coordinator node will accept finger print information input, when the input finger print information and the Data Matching of fingerprint base successfully be to send the controlled in wireless instruction, close and connect refrigerator, the difference of the controlled in wireless instruction of air-conditioning power supply is distinguished by the variable among the FLASH that is stored in CC2530; After sending the wireless instructions success, point out personnel operation success on duty for 6 times by the 5G3SD LED flash.
