[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0043] The present invention is applicable to scenarios where electronic table signs are used to indicate participants in large-scale conferences, entertainment and other occasions, and takes displaying the names of participants in large-scale conferences as an example.

[0044] At present, some table cards on the market are unnumbered. The corresponding workflow is: after searching the current table cards on site through Bluetooth or WiFi, the list is sent to the electronic table cards in random order. After the sending is completed, they are placed one by one. In this way, if the meeting continues and the participants keep changing, the staff needs to keep collecting them, sending them out, and then placing them. Then, the next meeting will be held, and then they will be collected, sent out, and placed again. This undoubtedly increases a lot of trouble and the probability of errors. In addition, some electronic table cards are pre-set with numbers to correspond to the list numbers on the software. In this way, when sending them in batches, the names can be sent to the corresponding table cards, thereby solving the above-mentioned problem of repeated placement. For multiple meetings, as long as the table cards are left there and not moved, just change the list. However, the staff needs to be careful and serious. If the placement is wrong, the people in the seats will not correspond to the names on the table cards, which will cause a misunderstanding. For example, if the electronic table card used by Zhang San in the list is No. 1, and the electronic table card No. 1 is placed in seat No. 2, and the electronic table card No. 2 is placed in seat No. 1, then the electronic table card of seat No. 2 will show Zhang San, but there is no Zhang San in seat No. 2, so there is an error, which can only be corrected manually. However, if it is found during the meeting that the table card name and the seat person do not match, then the meeting process will be disrupted, causing a bad impact.

[0045] Moreover, if at the end of a day's meeting, some meetings require table cards, while others do not, the staff will have to collect, place, collect, and place them constantly. If time is tight, they must not place them incorrectly, and the table card numbers must correspond to the people in the seats. This is also a relatively high requirement for the staff, and because they will be placed together after collection, when placing them, they need to find the corresponding numbers and seats, which is very time-consuming. If the participants are curious and play with them before the meeting starts, they may pick them up and look at them casually, and then place them casually, which will cause the positions that the staff have placed before the meeting to be messed up, which will cause the table cards and the seat people to not correspond.

[0046] Therefore, an embodiment of the present invention provides a method for positioning an electronic table sign, which updates the placement position of the electronic table sign to avoid manual placement errors.

[0047] According to an embodiment of the present invention, an embodiment of a method for locating an electronic table card is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0048] In this embodiment, a method for positioning an electronic table card is provided, which can be used for the above-mentioned electronic table card. Figure 1 is a flow chart of a method for positioning an electronic table card according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0049] Step S101, detecting whether a radio frequency signal is read, the radio frequency signal is emitted by a radio frequency tag pre-fixed at a preset position on the table.

[0050] Specifically, in an embodiment of the present invention, the electronic table cards include Android electronic table cards and ink screen electronic table cards. The ink screen electronic table cards are further divided into Bluetooth ink screen electronic table cards and Wifi ink screen electronic table cards, which are used to display according to the name issued by the remote server. Radio Frequency Identification (RFID) devices are pre-deployed in the electronic table cards. Radio Frequency Identification technology, also known as electronic tags and wireless radio frequency identification, is a communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and the specific target. In an embodiment of the present invention, the radio frequency tag is pre-fixed at a specific position on the conference table. The specific position is determined according to habit. This position can also be marked as a fixed position for the table card, providing instructions for staff to quickly place and store them without paying attention to the table card number, where to put it, etc., and the participants can accurately place the corresponding position after picking it up. When the venue needs to be arranged, just place the electronic table card at a fixed position on the conference table. The radio frequency identification device of the electronic table sign will read the radio frequency signal. When the electronic table sign is placed on the radio frequency tag of the conference table, the radio frequency signal emitted by the radio frequency tag can be read. If it is not read, it proves that the electronic table sign is not placed at this time, so there is no need to name it.

[0051] Step S102: If a radio frequency signal is read, a tag code of the radio frequency tag is determined according to the radio frequency signal, and the tag code is sent to a remote server.

[0052] Specifically, in an embodiment of the present invention, each conference table is fixed with a radio frequency tag, and each radio frequency tag corresponds to a unique tag code, representing a unique conference table. In general, after the conference room is arranged, the position of the conference table in the conference room will basically not change, so the position of the table can be directly determined according to the tag code, for example, number one corresponds to table number one, number two corresponds to table number two, for example only, not limited to this. When the electronic table sign is placed at the radio frequency tag of the conference table, the built-in radio frequency identification device can identify the read radio frequency signal, determine the tag code of the radio frequency tag, and send the tag code to the remote service end via Bluetooth or Wifi.

[0053] Step S103, receiving the table card information after the remote server updates the location according to the tag code.

[0054] Specifically, in the embodiment of the present invention, corresponding software is deployed on the remote server, and the staff can determine the correspondence between the names and the tables according to the list of participants, so each label code corresponds to each name. When the remote server receives the label code sent by the electronic table card, it can determine the conference table position corresponding to the label code, and then determine the table card information of the electronic table card according to the correspondence between the name and the table, including the table card number and table card content of the current electronic table card. The table card content corresponds to the name of the participant who should be seated at this conference table, but is not limited to this, and can also include content such as the conference theme.

[0055] The positioning method of the electronic table card provided by the present invention reads the radio frequency signal emitted by the radio frequency tag pre-fixed at the preset position of the table, sends the tag code determined according to the radio frequency signal to the remote service end, and the remote service end updates the position according to the tag code, and receives the table card information after the position update. The present invention can directly determine the table position where the electronic table card is located according to the tag code of the radio frequency tag by reading the radio frequency signal emitted by the radio frequency tag at the fixed position of the table based on the radio frequency identification technology. The staff does not need to pay attention to the placement order of the electronic table card on different tables. They only need to place it at the fixed position of the table to obtain the updated table card information, avoid the errors that may be caused by manual operation, save energy and time, and improve the placement efficiency of the electronic table card.

[0056] In this embodiment, a method for positioning an electronic table card is provided, which can be used for the above-mentioned electronic table card. Figure 2 is a flow chart of a method for positioning an electronic table card according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0057] Step S201: When the RFID device detects an external RF field at a preset time interval and generates a wake-up signal, it ends the sleep state based on the wake-up signal and reads the RF signal emitted by the RF tag in the external RF field.

[0058] Specifically, in the embodiment of the present invention, the ink screen electronic table card is taken as an example, and an MCU (Microcontroller Unit) is also deployed in the electronic table card, and the radio frequency identification device adopts the automatic carrier detection mode, that is, the radio frequency identification device automatically and intermittently detects the external magnetic field. When the electronic table card is initialized, the RFID detection is turned on. During this process, the MCU is in a dormant state, and the MCU will not interfere with this process, which can increase stability and reduce power consumption, thereby meeting the low power consumption characteristics of the ink screen electronic table card. Figure 3As shown, the RFID device detects the external RF field at preset time intervals. When the electronic table card is placed at the RF tag, the external RF field formed by the RF tag can be detected, thereby generating a wake-up signal to wake up the MCU, and the MCU reads the RF signal of the external RF field at this time. If it cannot be read, it proves that the RF tag is not within the recognition range. It may be to prevent the correct position, or it may detect other external RF fields. At this time, the MCU will re-enter the sleep state.

[0059] Step S202: Detect whether a radio frequency signal is read. The radio frequency signal is sent by a radio frequency tag that is pre-fixed at a preset position on the table. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0060] Step S203: If a radio frequency signal is read, the tag code of the radio frequency tag is determined according to the radio frequency signal, and the tag code is sent to the remote server. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0061] Step S204, receiving the table card information after the remote server updates the location according to the tag code. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0062] Step S205, displaying the table card information, which includes the table card number and the table card content.

[0063] Specifically, in the embodiment of the present invention, the staff puts the electronic table card at the corresponding RFID tag position on the conference table, such as Figure 3 As shown, when the RFID device reads the RFID tag, it sends the tag code of the identified RFID tag to the remote server, which includes a server or APP. The remote server determines the location of the electronic table card according to the tag code, and then determines the table card number of the electronic table card after the location is updated, and determines the table card content to be displayed on the electronic table card according to the preset location information, and sends the table card number and table card content to the electronic table card for display. After the display is completed, the MCU re-enters the sleep state and waits for the next RFID detection interrupt to trigger wake-up. After entering the conference room, participants can directly find their location based on the display interface of the electronic table card.

[0064] The positioning method of the electronic table card provided by the present invention reads the radio frequency signal emitted by the radio frequency tag pre-fixed at the preset position of the table, sends the tag code determined according to the radio frequency signal to the remote service end, and the remote service end updates the position according to the tag code, and receives the table card information after the position update. The present invention can directly determine the table position where the electronic table card is located according to the tag code of the radio frequency tag by reading the radio frequency signal emitted by the radio frequency tag at the fixed position of the table based on the radio frequency identification technology. The staff does not need to pay attention to the placement order of the electronic table card on different tables. They only need to place it at the fixed position of the table to obtain the updated table card information, avoid the errors that may be caused by manual operation, save energy and time, and improve the placement efficiency of the electronic table card.

[0065] In this embodiment, a method for positioning an electronic table card is provided, which can be used for the above-mentioned remote service end, such as a server, an APP, etc. Figure 4 is a flow chart of a method for positioning an electronic table card according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0066] Step S401, receiving the tag code sent by the electronic table card.

[0067] Specifically, in the embodiment of the present invention, the remote server and the electronic table card are wirelessly connected via Bluetooth or Wifi. The specific connection method is determined by the wireless signal generating device of the electronic table card and is not limited here. When the staff places the electronic table card at the position of the radio frequency tag on the conference table, the electronic table card can read and identify the tag code of the radio frequency tag and send the tag code to the remote server via wireless communication.

[0068] Step S402, updating the position correspondence between the electronic table card and the table based on the tag code, and determining the table card information of the electronic table card according to the position correspondence, the table card information including the table card number and the table card content.

[0069] Specifically, in an embodiment of the present invention, the staff will determine the seating position of each participant in advance based on the list of participants. Each radio frequency tag on the conference table corresponds to a unique tag code. When the electronic table card on the conference table recognizes the tag code, the position correspondence between the electronic table card and the table is updated based on the tag code, and the table card number of the electronic table card is determined after the position is updated. Under normal circumstances, the tag code and the table card number correspond to each other from small to large, and confusion cannot be ruled out, but the position correspondence is unique. Even if they are placed in a disorderly manner, as long as the list in the software is correct, it will not cause the problem of inconsistency between the participants, the list, and the table card display.

[0070] Step S403, sending the table card information to the electronic table card.

[0071] Specifically, in the embodiment of the present invention, as long as the correspondence between the electronic table cards and the tables is determined, the electronic table cards can be sorted, the table card numbers and table card contents of each electronic table card can be determined, and the table card numbers and table card contents can be uniformly sent to each electronic table card via Bluetooth or Wifi. The electronic table card displays the table card number and table content to provide guidance for the participants.

[0072] The positioning method of the electronic table sign provided by the present invention updates the position correspondence between the electronic table sign and the table according to the tag code recognized by the electronic table sign, determines the table sign information of the electronic table sign, and sends it to the electronic table sign. The position of the table where the electronic table sign is located can be directly determined according to the tag code of the radio frequency tag. The staff does not need to pay attention to the placement order of the electronic table sign on different tables. They only need to place it at a fixed position on the table to obtain the updated table sign information, thereby avoiding errors that may be caused by manual operation and saving energy and time.
