Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a remote control positioning system according to the present invention. As described with reference to fig. 1, the system comprises: a locating tag 10 and a remote locating device 20. The positioning tag 10 is used in cooperation with the remote control positioning device 20, wherein the positioning tag 10 is connected with an article to be positioned, i.e. the corresponding article to be positioned can be found by positioning the positioning tag 10.
The positioning tag 10 is configured to send a feedback signal to the remote control positioning device 20 after identifying a positioning signal of a fixed frequency sent by the remote control positioning device 20.
The remote control positioning device 20 determines the position of the positioning tag 10 according to the feedback signal sent by the positioning tag 10.
Fig. 2 is a schematic structural view of a remote control positioning device according to the present invention. Referring to fig. 2, the remote control positioning device 20 includes: a first transmitting unit 201, a processing unit 202, a plurality of signal receiving units 203 arranged in parallel, and positioning indicator lamps 204 corresponding to the plurality of signal receiving units 203 one by one; the plurality of signal receiving units 203 are uniformly disposed on the housing of the positioning remote control device 20. The one-to-one correspondence between the signal receiving unit 203 and the positioning indicator 204 means that the signal receiving unit 203 and the corresponding positioning indicator 204 are on the same radius with the center of the remote control positioning device as the center of the circle.
Wherein the first transmitting unit 201 transmits a positioning signal of a fixed frequency according to an input user instruction. In a specific implementation manner of the present invention, when a positioning operation is required, a positioning signal with a fixed frequency corresponding to the positioning tag 10 is sent according to the positioning tag 10 corresponding to the object to be positioned. The positioning tag 10 returns a corresponding feedback signal after receiving the positioning signal of the fixed frequency.
The signal receiving unit 203 sends the received feedback signal to the processing unit. Since a plurality of signal receiving units 203 are distributed on the housing of the remote control positioning device 20, the signal receiving units 203 are arranged in parallel; thus, each signal receiving unit 203 is capable of receiving the feedback signal and transmitting the received feedback signal to the processing unit 202.
The processing unit 202 confirms the signal receiving unit 203 that transmits the feedback signal earliest according to the time at which each signal receiving unit 203 transmits the feedback signal, and lights the positioning indicator lamp 204 corresponding to the signal receiving unit 203 to indicate the direction in which the positioning tag 10 is located. Since the signal receiving units 203 are uniformly disposed around the center of the position remote control 20, the distance between each signal receiving unit 203 and the position tag 10 is different, which results in that the time for which each signal receiving unit 203 receives the feedback signal is also different. So that the position in which the positioning tag 10 is located is determined based on the time at which the feedback signal is received.
Further, by sending the positioning signal for multiple times, receiving the feedback signal of the positioning tag 10 for multiple times, the direction of the positioning tag 10 is adjusted until the positioning tag 10 is found and the corresponding article to be positioned is found.
It can be seen that, in the present invention, by connecting the positioning tag 10 with the object to be positioned, when the object to be positioned needs to be found, the remote control positioning device 20 sends a positioning signal with a corresponding fixed frequency, then determines the specific orientation of the positioning tag 10 according to the feedback signal of the positioning tag 10, and positions for multiple times until the object to be positioned is found. The technical scheme provided by the invention has no satellite navigation positioning chip, does not depend on satellites, and can be applied to scenes with poor satellite signals. The existing remote control positioning technology depends on satellite signals, and has the defects of high power consumption, high cost and small application range.
Fig. 3 is a schematic structural view of a positioning tag according to the present invention. As described with reference to fig. 3, the positioning tag 10 includes: an antenna unit 101, a frequency selection amplifying unit 102, an identifying unit 103, a second transmitting unit 104 and an energy storage unit 105. In order to distinguish the transmitting unit in the remote control positioning device 20 from the transmitting unit in the remote control positioning device 20, the transmitting unit in the positioning tag 10 is the second transmitting unit 104, and the transmitting unit in the remote control positioning device 20 is the first transmitting unit 201. The following is the same.
The frequency selecting unit 102 is configured to receive a positioning signal with a fixed frequency through the antenna module 101, and send the received positioning signal to the amplifying unit.
In a specific embodiment of the present invention, the antenna unit 101 is configured to receive a positioning signal or transmit a feedback signal. I.e. the antenna unit 101 receives a positioning signal of a fixed frequency corresponding to the positioning tag 10 or transmits a feedback signal corresponding to the positioning tag 10.
In one embodiment of the present invention, the frequency-selective amplifying unit 102 is a filtering amplifying circuit, which is used to receive only the positioning signals with the specified frequency, filter the positioning signals with other frequencies, and amplify the positioning signals with the specified frequency obtained by filtering. The location signal with the specified frequency obtained by filtering means that the frequency of the location signal is the same as the fixed frequency of the location tag 10.
Fig. 4 is a schematic diagram of an amplifying circuit in a frequency selective amplifying unit according to the present invention. Wherein the core chip of the operational amplifier is LM385. Wherein LM385 is a low power voltage reference diode.
The identifying unit 103 is configured to identify the tag number in the positioning signal, and determine whether the tag number is consistent with the tag number of the positioning tag 10. In a specific embodiment of the present invention, the identification unit 103 may be specifically an SN74AUP1T00 chip manufactured by texas instruments, and is capable of reading information carried in a carrier frequency, i.e. capable of completing an operation of reading a tag serial number carried in a positioning signal.
The second transmitting unit 104 transmits a feedback signal carrying the fixed frequency of the positioning tag 10 and the tag serial number through the antenna unit 101 according to the identified positioning signal. That is, in the present embodiment, the feedback signal transmitted by the second transmitting unit 104 carries the fixed frequency and the tag number of the present positioning tag 10.
The energy storage unit 105 is used for providing electric energy for the whole positioning tag 10.
In one embodiment of the invention, the energy storage unit 105 stores energy for use by the frequency selective amplifying unit 102, the identifying unit 103 and the second transmitting unit 104. Preferably, from the aspect of usage, the energy storage unit 105 may use a disposable battery, such as a button cell; rechargeable batteries may also be used, and the charging mode may be solar charging or electromagnetic charging. Since the frequency of the feedback signal transmitted by the positioning tag provided in the present invention is low and only the amplifying and identifying operations of the positioning signal after filtering are required, the power consumption of the positioning tag 10 is low.
In one embodiment of the present invention, the remote location system includes a plurality of location tags 10; wherein each positioning tag 10 corresponds to a different fixed frequency and a different tag number.
In the case where the number of positioning tags is too large, it is not sufficient to assign a fixed frequency to each positioning tag individually, in one embodiment of the present invention, a plurality of positioning tags 10 may correspond to the same fixed frequency, but the tag numbers of each positioning tag are different. That is, in the process of judging the positioning signal, the identification unit 103 inside the positioning tag 10 identifies the corresponding tag serial number, and judges whether the tag serial number carried by the positioning signal is the same as the tag serial number of the positioning tag, so as to judge whether to send the corresponding feedback signal. When the label serial number in the positioning signal is the same as the positioning label, the positioning signal is indicated to be aimed at the positioning label, and the identification is passed, and a corresponding feedback signal is sent. The positioning operation for the specified positioning tag 10 is completed. When the label serial number in the positioning signal is different from the positioning label, the positioning signal is indicated to be not specific to the positioning label, the identification is not passed, and no operation is performed on the positioning signal.
In the above-described embodiment of the present invention, since each positioning tag 10 can only receive the positioning signal of the corresponding fixed frequency through the frequency selective amplifying unit 102. The method comprises the following steps: when a positioning signal is received, other interference signals are filtered through the frequency-selecting amplifying unit 102, and signals meeting the frequency and amplitude requirements are amplified; then, the identification unit 103 identifies and confirms that the tag number in the positioning signal is identical to the tag number in the positioning tag. After the correct identification, a feedback signal with a fixed frequency with the tag number is transmitted to the outside via the second transmitting module 104.
In one embodiment of the present invention, the positioning tag 10 may be manufactured in a stick type, a pendant type, or other forms according to the actual needs of the object to be positioned. So long as the interconnection with the article to be positioned is accomplished. Furthermore, in order to be able to achieve permanent positioning of the item to be positioned, the positioning tag 10 may be fitted inside the item to be positioned.
In one embodiment of the invention, each positioning tag 10 corresponds to a different frequency and a different tag number. The fixed frequency and tag serial number solidify within the locating tag 10. Preferably, in order to facilitate the operation of the user and improve the user experience, the fixed frequency and the tag serial number of the positioning tag 10 may also be stored in the remote control positioning device, for example, the frequency corresponding to the first positioning tag (the first one refers to one of the positioning tags and does not refer to the serial number of the positioning tag) is fixed to 31MHz, and the tag serial number is 001. When the first positioning tag is used, a first positioning tag serial number 001 is found in the remote control positioning device 20, and the identification information of the article to be positioned bound by the first positioning tag is edited and activated. If the identification information of the article to be positioned is a watch, binding the first positioning label serial number 001 with the watch and storing the first positioning label serial number in a corresponding relation table.
In practice, the system configuration is completed by attaching or hanging the first positioning tag to the wristwatch. When the wristwatch needs to be positioned, a first positioning label corresponding to a wristwatch item is searched in a corresponding relation table on the remote control positioning device 20, and after the first positioning label is determined, the remote control positioning device 20 sends a positioning signal according to the fixed frequency 31MHZ and the label serial number 001 corresponding to the first positioning label stored in the corresponding relation table.
In the invention, the provided positioning tag 10 has the advantages of low cost, low power consumption, small volume, capability of being made into various forms such as sticking type, hanging type and the like according to actual needs, convenient positioning of keys, high use frequency of earphone and the like, low economic value and easy loss on daily articles; the positioning labels can be manufactured in batches, so that the technical scheme provided by the invention can be also suitable for searching materials in industrial production warehouses. The existing remote control positioning technology depends on satellite signals, and has the defects of high power consumption, high cost and small application range.

The identification of the article to be positioned can be an ID or a name of the article to be positioned. Table I is a corresponding table in the present invention

List one
The remote control positioning device 20 stores a table of correspondence between positioning tags and articles to be positioned. In a specific embodiment of the present invention, the correspondence table stores information of the fixed frequency of the positioning tag and the tag serial number in advance. And then solidifying the pre-stored corresponding relation table into the remote control positioning device. Specifically, one remote control positioning device 20 matches a plurality of positioning tags 10, and the matched plurality of positioning tags 10 are stored in a correspondence table.
In an actual usage scenario, there is a case where the positioning tag 10 is not used enough, so it is also necessary to be able to add the positioning tag to the correspondence table.
In one embodiment of the present invention, the processing unit 202 stores the fixed frequency and the tag number of the positioning tag 10 in the correspondence table according to the information including the fixed frequency and the tag number of the positioning tag 10 input by the input unit 205.
In a specific embodiment of the present invention, the processing unit 202 stores the fixed frequency and the tag serial number of the positioning tag 10 carried in the feedback signal into the correspondence table according to the feedback signal received by the signal receiving unit 203. Namely, in the present embodiment, the remote control positioning device 20 obtains the fixed frequency and the corresponding tag serial number of the positioning tag 10 to be input through the sweep operation; and returning a feedback signal returned according to each positioning label 10, and storing the fixed frequency of the positioning label 10 and the corresponding label serial number into a corresponding relation table.
In a specific embodiment of the present invention, the processing unit 202 stores the identification of the to-be-located object in the correspondence table corresponding to the selected location tag 10 according to the input of the user instruction containing the identification of the to-be-located object by the input unit 205. In the present embodiment, a plurality of positioning tags 10 are already stored in the correspondence table, so when the positioning tag 10 needs to be used, only the identification of the article to be positioned needs to be input into the correspondence table, and the identification corresponds to the positioning tag 10. Such as associating the watch with the first location tag.
In a specific embodiment of the present invention, in order to obtain a better positioning effect, a plurality of detecting antennas 210 are disposed on a housing of the remote control positioning device 20, and a signal receiving unit 203 is uniformly disposed on each detecting antenna 210.
In a preferred embodiment of the present invention, there are four probe antennas 210 extending, and adjacent probe antennas 210 are disposed at right angles. And, one signal receiving unit 203 is provided on each of the probe antennas 210.
In actual use, the remote control positioning device 10 has a plurality of parallel signal receiving units 203, and the signal receivers 203 are distributed over a plurality of extended probe antennas 210 of the remote control positioning device 20. Since the detecting antennas 210 are uniformly radially arranged around the remote control positioning device 20, the distance between each detecting antenna 210 and the object to be positioned is different, which results in different time of the positioning signal received by each signal receiving unit 203. When a signal receiving unit 203 receives a corresponding feedback signal, the feedback signal is transmitted to the processing unit 202, and the processing unit 202 will light the positioning indicator lamp 204 corresponding to the feedback signal and inhibit the signal input of other signal receiving units 203. So that only the positioning indicator 204 on the feeler 210 nearest to the article to be positioned is lit. Preferably, the effective operation can be displayed on the display unit 206, so that the user can move a certain distance in the direction indicated by the detecting antenna 210. Repeating the above operation for multiple times until the object to be positioned is found.
In summary, in the invention, the positioning tag is connected with the object to be positioned, when the object to be positioned needs to be found, the remote control positioning device sends the positioning signal with the corresponding fixed frequency, then the specific direction of the positioning tag is determined according to the feedback signal of the positioning tag, and the object to be positioned is positioned for multiple times until the object to be positioned is found. In addition, in order to locate more economically and conveniently, lost objects are found, and the locating label can be conveniently fixed with the located object without obstructing the use or carrying of the located object. And secondly, the remote control positioning device provided by the invention has no GPS navigation positioning chip, reduces dependence on satellites, reduces the use cost and increases the success rate of positioning. Based on the above situation, the technical features disclosed by the invention can be widely applied to the scenes of poor satellite signals or used for positioning keys, headphones and other daily articles which have high use frequency, low economic value and easy loss. The method solves the defects that the existing remote control positioning technology depends on satellite signals, and has large power consumption, high cost and small application range.
