Description
Affiliated technical field
Patent of the present invention relates to a kind of RF (Radio Frequency) card micro-wave oven, especially contactless the swiping the card of a kind of RF of use card carried out the micro-wave oven that charging is used, and is adapted at the public places such as hospital, school and office building and is used for providing micro-wave oven paid utilization service for people.
Background technology
To improving constantly that quality of life requires, need a kind of operation reliable, convenient along with people, can provide in public places such as hospital, school and office buildings charging to use the micro-wave oven of service.The common microwave stove that can see in the market uses towards family mostly, do not possess charging and use function, someone has proposed coin-operated microwave oven, also someone has proposed the IC-card charged microwave oven, although these micro-wave ovens can be realized charging and use function, but the form of charging is not advanced especially, Shortcomings.For example coin-operated microwave oven requires the user must get coin ready, and the counterfeit money discrimination is not very high, and mechanical fault easily occurs coin-freed arrangement; The IC-card charged microwave oven requires the user IC-card must be aimed at the card reading slot insertion wherein, require positive and negative, the fore-and-aft direction of IC-card also to act without fail, and easily or loose contact stained because of the electrical contact of IC-card seat and IC-card causes and can't use, and it is unreliable to operate, convenient not.
Unreliable for the operation that overcomes above-mentioned charged microwave oven, not enough not easily, the invention provides the micro-wave oven that a kind of RF of use card carries out the contactless charging of swiping the card---RF card charging micro-wave oven, the user only needs RF is stuck in " district swipes the card " that marks on the inherent micro-wave oven panel of coverage and brushes, can charging use micro-wave oven that food is heated, easy to operate, reliable.It can independently use by separate unit, carries out the center charge accounting by network after also can being connected with switch by the RJ-45 interface of configuration.
The technical solution adopted for the present invention to solve the technical problems is: RF card charging micro-wave oven, it is included in the built-in control module of micro-wave oven, display module and RJ-45 interface module, it is characterized in that also being included in the built-in RF card module for reading and writing of micro-wave oven, this module is connected with control module, by radio frequency, the RF card is carried out contactless read-write operation, the coding of operating result is given control module, microprocessor in control module calculates the microwave-oven-heating timing according to this coding, controls the microwave-oven-heating circuit and heats.Display module is connected with control module by signal wire, receives the demonstration information that control module is sent here, shows the charging amount of money, RF card account balance and heating timing, and micro-wave oven begins to heat rear demonstration countdown, also can show this micro-wave oven accumulative total toll amount.The micro-wave oven panel no longer arranges the fixed cycle operator knob or key is set.The RJ-45 interface module is connected with the microprocessor of control module by signal wire, RJ-45 standard interface in this module is placed in the micro-wave oven sidepiece, when micro-wave oven links by RJ-45 interface and external switch, complete the conversion of TCP procotol and interface level, can carry out the network billing clearing to the RF card under programmed control, because the RF jig has a plurality of subregions, each subregion has password and the access consideration of oneself, can one card for multiple uses, thereby the RF charged microwave oven can realize in network that " all-purpose card " charging uses.
The invention has the beneficial effects as follows, use the RF card to carry out the contactless charging of swiping the card and control the microwave-oven-heating timing, not only reach the purpose that charging is used, and billing operation is reliable, meets people's operating habit.RF card charging micro-wave oven can use by separate unit, also can connect with switch by the RJ-45 interface and realize the network billing clearing, and then realize " all-purpose card " charging in network, be adapted at the public places such as hospital, school and office building and be used to provide micro-wave oven paid utilization service.

Embodiment
Below in conjunction with accompanying drawing, invention is elaborated.
As shown in Figure 1, control module (6), display module (8), RJ-45 interface module (9) and RF card module for reading and writing (7) all are placed in microwave cabinet.The model of the RF card module for reading and writing (7) that adopts is MF-30E, and it is connected with microprocessor in control module (6), and this module is completed the contactless read-write operation to RF card (10), and the coded signal of operating result is given microprocessor; The model of the RJ-45 interface module (9) that adopts is TCP51, and it also is connected with microprocessor in control module, and the RJ-45 interface (5) in this module links with outside switch, completes the conversion of TCP procotol and interface level.
As shown in Figure 2, after the RF card was swiped the card and set heat time heating time, the user started microwave-oven-heating and begins countdown by startup/pause button (1); Firepower control handle (2) is set the heating power of micro-wave oven; Swiping the card the amount of money and heat time heating time of light-emitting diode display (3) display setting begins to heat rear demonstration countdown; " district swipes the card " (4) indicating user is held RF and is stuck in this zone and swipes the card; A RJ-45 standard interface (5) is left in RF card charging micro-wave oven side, and this interface is connected with built-in RJ-45 interface module, is used for being connected with switch, realizes the networking charge accounting of swiping the card.Initializing circuit after start, if the state that detects is normal, the RF charged microwave oven enters waiting status, and RF card module for reading and writing is in the card seeking state, and display flashes demonstrations " swipe the card 0.5 elementary time 0 minute " printed words, points out user card punching; After RF card module for reading and writing recognizes effective card and successful charging, send corresponding coded signal to control module, control module is calculated the heating timing according to this coding and preset value, send display module to show result, as " swipe the card 0.5 elementary time 3 minutes ", loudspeaker provides prompt tone simultaneously.The user presses " start/suspend " button, and control module provides enabling signal and controls the microwave-oven-heating control circuit, the beginning heat food, and display module shows countdown; Arrive heat time heating time, and control module is turn-offed the microwave-oven-heating control circuit and provided auditory tone cues; The account that runs into the RF card is not pointed out by caution sound; Also can be connected with switch by the RJ-45 interface and realize swiping the card the networking clearing of charging.
