As shown in FIG. 1 , it is a schematic diagram of a digital home appliance system 100 according to an embodiment of the present invention, wherein the digital home appliance system 100 can be controlled by three battery-less cascade remote control devices 110 , 112 , 114 . The digital home appliance system 100 may include various digital home appliances, such as a personal computer, a security camera, a television set capable of receiving broadcast programs and Internet pay programs, or a fax telephone. It is very important to properly manage the access rights of these digital home appliances. In this embodiment, the digital home appliance system 100 is connected to various digital home appliances through the intranet, and the digital home appliance system 100 is controlled hierarchically through the central control reader 120 . The battery-less cascade remote control devices 110, 112, 114 can be classified into parent control cards, child control cards and guest control cards in the digital home appliance system 100. Each has a different class of access rights.

As shown in FIG. 2 , it is a schematic diagram of an embodiment of the batteryless cascade remote control device 110 of the present invention. The batteryless cascade remote control device 110 includes an RFID circuit 210 with a non-volatile memory 215 and an antenna 220 . The radio frequency identification circuit 210 is coupled to the antenna 220, and the non-volatile memory 215 records a specific identification number and class information, and the class information includes access control permission, content control, play-list ), links, personal configuration settings (personal configuration), stored data (saved data), etc., and class information is set via the central control reader 120, or via a personal computer equipped with a radio frequency identification reader function (not icon) to set. Non-volatile memory 215 can be read-only memory, fuse memory, voltage elimination type programmable read-only memory (electrically erasable programmable read-only memory, EEPROM), or flash memory, etc. With the above-mentioned remote control device, parents can prevent themselves from The children of children can make pornographic calls or pay calls, and can manage the quota of watching premium programs. By using radio frequency identification technology, a low-cost battery-free remote control device 110 can be realized. For example, the battery-free remote control device 110 can be It is realized by a radio frequency identification circuit 210 and a keyboard comprising plural (the so-called "plural" in the present invention means multiple meanings, at least two or more) buttons. After removing the limited power provided by the battery After the limitations of the battery-less cascaded remote control device 110 can have many different shapes and sizes, for example, its size can be the same as a pocket or a credit card, or smaller than a credit card for the convenience of general users Carry. Each batteryless step-type remote control device 110, 112, 114 has a unique identification code, so some remote control devices can be exclusively owned by parents, and some remote control devices can be exclusively owned by children. Each remote control device can be identified in the identification code. Add some specific codes to provide different levels of program access, such as based on the commonly known V-chip (a computer chip or other electronic device that prevents viewing of excessively violent or pornographic TV programs). Each battery-free cascade remote control device 110, 112, 114 all has its unique identification code, which can be used to set time limits. For example, the remote control device used by parents can track personal favorite channel settings, etc. Or, for pay-per-view programs, important information such as personal budgets and program time limits can be managed individually for pay-per-view programs, and the credit cards used to pay for these pay-per-view programs can be linked on or pre-registered on each of the battery-less cascaded remote control devices 110, 112, 114. For example, credit card payment information can be appropriately programmed in non-volatile memory and individually associated with each user (at home). Note that class information can be stored in the non-volatile memory 215 or in the digital appliance, while the identification code is stored in the batteryless class remote control 110, 112, 114. Thus, program payment is very fast, secure and managed.

As shown in FIG. 3 , it is a schematic diagram of an RFID control packet 300 transmitted by the battery-less cascade remote control device 110 , 112 , 114 , including a preamble, an identification code, and a data code. Different data codes are transmitted in response to different buttons on the batteryless cascade remote control 110 , 112 , 114 pressed by the user; the identification code distinguishes the batteryless cascade remote control 110 , 112 , 114 .

As shown in FIG. 4 , it is a schematic diagram of remote control of a television 420 in a digital home appliance system 400 by using a batteryless cascade remote control device 410 in another embodiment of the present invention. The television set 420 can receive programs provided by the Internet or a cable TV channel system. Communication links of computers, the Internet, and digital communication systems can be individually managed, such as user restrictions such as program viewing and time. Preferably, the TV 420 is integrated with a radio frequency identification reader (not shown), and authorized users can directly use the TV 420 to manage each user's right to watch TV programs.

As shown in FIG. 5 , it is a schematic diagram of remote control of a digital home appliance system 500 by using a batteryless cascade remote control device 510 according to another embodiment of the present invention. The television set 520 can receive programs from the Internet or a cable TV channel system. In this embodiment, the television set 520 sold by the retailer is equipped with a battery-free cascade remote control 510 and a parent RFID card 512, and the parent RFID card 512 It is a golden RFID card with the highest authority, which has the highest access right. The batteryless cascade remote control 510 has a plurality of control buttons, and all family members share the batteryless cascade remote 510 to control the TV 520; the TV 520 is integrated with a radio frequency identification reader, and the batteryless cascade remote 510 is integrated with a radio frequency identification circuit (not shown). Similarly, different data codes are transmitted corresponding to different buttons on the battery-less cascade remote control device 510 pressed by the user to control the television 520 . The RFID reader of the television 520 (or digital appliance) records the relevant class information in the non-volatile memory. Therefore, the battery-less cascade remote control device 510 can determine whether the parent RFID card 512, the child RFID card 514, or the customer RFID card 516 is located near the TV 520, according to the stored information in the RFID reader. Hierarchical information to control (hierarchically control) television 520 hierarchically. RFID technology is beneficial to the limited effective detection distance in general households. As known, the effective distance of RFID technology can reach between three and ten meters in an environment without major obstacles. In the living room, the battery-less cascade remote control device 510 integrated with the RFID circuit can perform remote control operations in cascade without encountering the problem of remote control direction sensitivity of conventional remote controllers. Since the size of the radio frequency identification cards 512, 514, 516 can be extremely thin, each family member can easily keep his own radio frequency identification card. When the parents go out or stay in other rooms, the parent RFID card 512 is outside the effective receiving range of the TV set 520, so the parent's right to manage the class information of the TV set 520 is also prohibited. For example, if only a child is in the living room with the child RFID card 514, then the TV set 520 only detects the child RFID card 514, so the child can only watch the classes defined by the RFID reader as appropriate for the child. Information about programs that are allowed to be accessed. Preferably, the TV 520 can be set to adjust the effective distance of the radio frequency identification.

In Fig. 5, the parent RFID card 512 has the right to define class information in the RFID reader of the TV set 520. Preferably, the RFID cards 512, 514, 516 can be linked to the TV set by a cognitive program television set 520 or digital appliance. Parents can schedule class information when the parent places the parent RFID card 512 and a new RFID card 514 "reasonably close" to the TV set 520 for a predetermined length of time. The relatively close distance can be determined by the detection of the RF signal strength from the parent RFID card 512 and the RFID card 514. Preferably, the television 520 displays information related to the RFID cards 512 and 514 to confirm this knowledge The process is complete; by detecting that the distance between the parent RFID card 512 and the TV 520 is "very close", allowing parents to manage class information through the battery-free class remote control device 510. Then, the new RFID card 514 can be managed as a child RFID card 514 to obtain its corresponding subclass. By detecting the "very close" distance between the RFID card and the TV 520, parents can easily manage various Class information. Furthermore, before performing class information management, you can further request "password" or "biometric identification" (such as fingerprints, etc.) information. In this way, not only can the user's intention be confirmed, but also avoid Users (children) who do not have access rights to class information management perform a cognitive program to change class information. The batteryless class remote control device 510 can be placed in the living room and used by all family members. It should be noted that there is no The battery-level remote control device 510 does not need batteries to maintain its operation, is very light in weight, and can be very thin. Therefore, the battery-less remote control device 510 is not afraid of being damaged by the impact of falling to the ground or that the battery is not installed. Errors that are not easy to find such as correctness, dislocation, etc. Furthermore, because the batteryless remote control device 510 is thin and light, it can be conveniently stored in a small area without scratching the wood surface.

According to the disclosure above, those familiar with this field should be able to understand that the class information of the above-mentioned radio frequency identification cards 512, 514, 516 can be planned and managed by the radio frequency identification reader equipped with the TV or computer, wherein the class information Can include access control permissions, content controls, playlists, links, personal configuration settings, and other stored data. For many digital home appliances in the digital home appliance system, the class information of each family member can be managed by an RFID card. For example, the class information can define the total payment amount of paid programs on the Internet for each family member . Preferably, the "quite close" distance between the digital home appliance and the radio frequency identification card can be detected to facilitate the management of class information.

Please refer to FIG. 5 again to further illustrate the power consumption of the RFID reader in the TV 520 . The RFID reader transmits electromagnetic waves to detect whether the RFID cards 512 , 514 , 516 are within its effective detection range. If an RFID reader is constantly sending out electromagnetic waves 24/7, it will consume too much transmit power. Preferably, the radio frequency identification reader can poll the radio frequency identification card with predetermined periods of different lengths such as short, medium and long. For example, when the television set 520 is turned on, the RFID reader polls the battery-free cascade remote control 510 at a minimum predetermined period (i.e., the fastest frequency), such as about 100 milliseconds, as a typical person presses the remote control. The reaction time of the buttons on it is about 100 milliseconds or so. When the user continues to watch the same channel for a long time, the length of the polling cycle can be extended appropriately, but it should be noted that the user is still in the living room; The RFID reader periodically detects whether there is an RFID card within its effective detection range.

As shown in FIG. 6 , which is a flowchart of a power saving method for a batteryless remote control system according to a preferred embodiment of the present invention, it starts at step 600. In step 610, when the radio frequency identification reader confirms that all When the radio frequency identification card of the TV set 520 is outside its effective detection range, the radio frequency identification reader determines that all family members have gone out, and proceeds to step 620. Polling to save power, that is, polling at the slowest frequency, for example, about five seconds; Put down the items at hand or find the remote control first, because the RFID reader may complete the confirmation that someone has gone home when the user is unlocking the door. In step 630, when the RFID reader of the TV 520 detects When any one of the RFID cards 512, 514, 516 is within the effective detection range, the RFID reader polls the batteryless cascade remote control device 510 for a predetermined period of medium length, such as about two seconds. In step In 640, the radio frequency identification reader can decide to use a medium or short predetermined period according to the distance between the user and the TV set 520, and by detecting the strength of the radio frequency signal and the frequency of the user appearing in the effective detection range. Polling the battery-free cascade remote control device 510. Preferably, the effective detection range of the user's presence is greater than the effective range of the user's remote control TV 520. For example, the TV 520 detects the radio frequency identification card 512, The strength of the radio frequency signal returned by 514 and 516 determines whether the user appears based on the first effective detection range, for example, the range within a radius of twelve meters (meters) around, and whether the user is in the second effective detection range Determine whether the user intends to remotely control the TV 520 within the range, for example, the range within a radius of five meters around the TV 520.

As shown in FIG. 4 , it is a flow chart of the operation of the radio frequency identification reader contained in the TV or the central control reader 120 shown in FIG. 1 , and please refer to FIG. 1 at the same time. It starts from step 700; in step 710, the central control reader 120 or the radio frequency reader equipped with the TV periodically broadcasts electromagnetic waves to the battery-free step-type remote control devices 110, 112, 114, wherein the central control reader The reader 120 can be a central control radio frequency identification reader; in step 720, the central control reader 120 performs a handshake action with each batteryless cascade remote control device 110, 112, 114; in step 730, the central control reader Reader 120 receives the identification code and data packet of each battery-free class remote control device 110, 112, 114; in step 740, the central control reader 120 operates according to the control data and class information; after step 740 is executed , return to step 710.

As shown in FIG. 9 , it is a flowchart of a batteryless remote control method according to another embodiment of the present invention, and please also refer to FIG. 5 . The flow chart starts at step 900; in step 910, it is detected whether the radio frequency identification card (or radio frequency identification tag) is within its effective detection range. For example, if there are five members in the family, and only three of them are sitting in front of the TV 520, the RFIDs of these three members are detected to be within the effective detection range of the TV 520; 520 broadcasts electromagnetic waves to the battery-less cascade remote control device 510 . In step 930 , the TV 520 receives the control packet from the battery-less cascade control device 510 . In step 940, the TV set 520 operates according to the control packet and class information. Preferably, the class information is stored in the TV set 520, and the control packet includes a preamble, an identification code and a data code; A button activated on the remote control. Class information defines class access rights for all family members, including parent class access rights, child class access rights, and guest class access rights, for example. Each RFID identity is associated with one of the class access rights. Preferably, when a plurality of radio frequency identification cards are detected, the access right with the highest authority among them is given priority. Preferably, when no RFID ID is detected, the TV 520 will operate according to control packets and "general" class information, for example, a visitor may not have an RFID ID, so the pre-set It is assumed that the guest has a general class access right, preferably, it may be the least privileged of all class access rights. Alternatively, each level of access requires identification authentication, such as a password and/or biometric identification and/or radio frequency identification.

As shown in FIG. 10 , it is a flow chart of a method for programming class information belonging to radio frequency identification identities belonging to members through a television set according to an embodiment of the present invention, and please refer to FIG. 5 at the same time. This flow chart starts from step 1000; In step 1010, the authorized member (such as father) places his highest-authority RFID and the member's RFID within "quite close" range of the TV 520, which can be determined by the power strength of the RF signals from the two RFIDs. to decide. In step 1020, the TV 520 displays class information about the member's radio frequency identification. In step 1030, the authorized member manages the class information of the member's radio frequency identification via the battery-free class remote control device 510. Preferably, in Before managing member RFID class information, the television set 520 requires authentication information to confirm authorized member privileges, such as passwords or biometric identification information (such as fingerprints).

As shown in FIG. 11 , which is a flowchart of a batteryless remote control method according to another embodiment of the present invention, it starts at step 1100; in step 1110, the radio frequency identification reader emits electromagnetic waves. Then in step 1120, the batteryless cascade remote control device receives electromagnetic waves and supplies power accordingly. In step 1130, the RFID reader issues a command. In step 1140, the batteryless cascade remote control device responds to the command according to the activated button. Preferably, the batteryless cascade remote control device responds with "None", "Null ( ACK))", "identification code" or "key code (key code)", etc. In step 1150, the digital appliance operates according to the activated button and class information, which includes access rights permissions, content controls, playlists, links, personal configuration settings, payment balance, and storage data.
