[0027] In order to make the purpose, technical solutions, and advantages of the present utility model clearer, the preferred embodiments of the present utility model will be described in detail below to facilitate understanding by those skilled in the art. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0028] As Figure 1As shown in the figure, the described tour guide system includes a main control module 1, a wireless transceiver module 2, a voice module 3, a display module 4, and a power module 5. The main control module 1 is connected to the wireless transceiver module 2, and the voice output end of the main control module 1 is connected to the voice module; the display output end of the main control module 1 is connected to the display module 4; the power module 5 is connected to the above modules and provides power. The tour guide system also includes an electronic tag 6. The wireless transceiver module 2 is connected to the electronic tag 6 through a wireless signal for communication. The electronic tag 6 is placed at each scenic spot in the scenic area, and each scenic spot corresponds to its own electronic tag 6.

[0029] As Figure 2 shown in the figure, the main control module 1 adopts a single-chip microcomputer minimum system, using STC89C51RC. Because the minimum system composed of it is simple and reliable, as long as a clock circuit and a reset circuit are connected to its chip, the minimum system can work. The clock frequency is selected as 12MHz. The computer programs involved in the single-chip microcomputer minimum system are all existing data acquisition and display programs, which can be easily found on open-source program websites and are not the main body protected by the present utility model.

[0030] As Figure 3 shown in the figure, the wireless transceiver module 2 adopts RFID technology and uses an nRF24L01 chip. The nRF24L01 integrates all high-speed signal processing parts related to the RF protocol, can automatically retransmit lost data packets, automatically generate response signals, and works in the same frequency band as the electronic tag, and can read the information of the electronic tag. Five ports of the nRF24L01 chip, namely CE, CSN, SCK, MOSI, and MISO, are connected to an 8PIN socket. The 1st and 2nd ports of the 8PIN socket are connected to the 5VCC of the power module 5, and the 8th port is connected to the IRO port of the nRF24L01 chip; the VSS, DVDD, VDD, VSS, and IREF ports of the nRF24L01 chip are all grounded, and a 16M Hertz crystal oscillator is connected between the KC2 and KC1 ports; the VDD_PA and ANT1 ports are connected through an inductor L2 and then grounded; the ANT2 and ANT1 are directly connected through an inductor L1, and the ANT2 is also connected to a 2pin socket through an inductor L3.

[0031] The tour guide system also includes an environment detection module 4. The environment detection module 4 is connected to the main control module 1. The environment detection module is a temperature and humidity sensor for monitoring the surrounding environmental temperature and humidity and displaying them on the display module 4. The SHT20 or SHT21 digital temperature and humidity sensor is selected. They have an IIC interface built-in and can directly communicate with the single-chip microcomputer.

[0032] This method simplifies the wiring of the environmental detection module 7 and facilitates the transmission and processing of data. At the same time, since both SHT20 and SHT21 are digital sensors with high precision and stability, they can provide relatively accurate temperature and humidity detection effects.

[0033] The described voice module 3 uses WT588D. The WT588D voice module 3 adopts a one-wire serial control mode and is directly connected to the port of the single-chip microcomputer to send data to the single-chip microcomputer, directly realizing voice broadcast. Immediately after the voice playback stops, it enters the sleep mode, and the chip turns into a completely stopped state. The master single-chip microcomputer matches the information sent by the slave with the internal data information, finds the data information of the corresponding scenic area and sends it to the voice module 3, and converts the scenic area information into voice and plays it through the speaker. A loaded voice can be repeatedly called to multiple addresses. Each address bit can load up to 128 segments of voice at most. The voices within the address bit are played in combination. When the voice playback stops, it enters the sleep mode, and the chip turns into a completely stopped state.

[0034] The described display module 4 uses LCD1602 as the display module 4 to display the location of the scenic spot where it is located. It can display two lines of content in total, with 16 characters in each line. It is used to display scenic area information and conduct data comparison and analysis. The principle of the display module 4 is as Figure 6 shown.

[0035] The voltage of the single-chip microcomputer in the described power supply module 5 during operation is 5V, while the operating voltages of the voice module 3 and the wireless module are 3.3V. In order to make the system operate normally, a low-power voltage regulator LM1117 needs to be added at the input end to convert the 5V power supply voltage into a 3.3V operating voltage. In order to ensure that the output operating voltage accuracy is about 1%, a bandgap reference voltage for Zener regulation needs to be added to the module. LM1117 controls the current size to prevent the chip from overheating and affecting the phenomenon. The principle of the power supply module 5 is as Figure 5 shown.

[0036] The working process of the present utility model: When the tour guide system starts to work, the power supply module 5 will first provide stable power for the entire system. The main control module 1, that is, the single-chip microcomputer minimum system based on STC89C51RC, will connect the clock circuit and the reset circuit and start to operate.

[0037] Among them, the operating voltage of the wireless transceiver module 2 is 3.3V. It uses the nRF24L01 chip and conducts wireless signal connection with the electronic tag 6 of the scenic area. When the wireless module receives the scenic area information from the electronic tag 6, the main control module 1 will process and analyze the received data. In order to ensure a stable operating voltage, the power supply module 5 will convert the 5V power supply voltage into a 3.3V operating voltage through the low-power voltage regulator LM1117.

[0038] Find the scenic area data that matches the information of the electronic tag 6 and explain it. These data information will be sent to the voice module 3 and the display module 4. The voice module 3 uses WT588D, which can convert the data information into sound and directly broadcast it to tourists through the speaker. This module supports the single-wire serial port control mode and can be directly connected to the port of the single-chip microcomputer to achieve voice broadcast.

[0039] At the same time, the display module 4 will also receive the data information sent by the main control module 1. The display module 4 selects the LCD1602 screen, which can display the scenic area information of two lines and 16 characters. The display module 4 generates graphic-assisted voice explanations based on this information, enabling tourists to listen and watch at the same time and better understand the scenic area.

[0040] This tour guide system is very intelligent and can automatically switch the content of the broadcast and display according to the information of the electronic tag 6 in the scenic area. Compared with the traditional manual tour guide, it can greatly improve the management efficiency of the tourist scenic area and also enhance the tourist experience. The whole system has a simple and stable structure and good scalability, which is a good supplement to the traditional tour guide method.

[0041] It should be understood that the detailed description of the technical solutions of the present invention with the aid of the preferred embodiments is illustrative rather than restrictive. Those of ordinary skill in the art can modify the technical solutions recorded in each embodiment or make equivalent replacements for some of the technical features on the basis of reading the specification of the present invention; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of each embodiment of the present invention.
