[0018] The present invention is further described below through specific implementation methods.

[0019] The terms "first" and "second" appearing in the present invention are only for the convenience of description to distinguish different components with the same name, and do not indicate a sequence or primary and secondary relationship.

[0020] In the description of the present invention, the directions or positional relationships indicated by “up”, “down”, “left”, “right”, “front” and “back” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention. They do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0021] In addition, in the description of this application, unless otherwise specified, "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0022] See also Figure 1 to Figure 2 , an auxiliary calling device, including a main control module 10, a key module 20, a voice module 30, a proximity sensing module 40 and a display module 50. The key module 20 is connected to the main control module 10 to input a number or a control command. The voice module 30 is connected to the main control module 10 to broadcast the number in a loop, the display module 50 is connected to the main control module 10 to display the number, and the proximity sensing module 40 is used to detect whether a person is approaching. The main control module 10 is connected to the proximity sensing module 40 to control the voice module 30 to stop broadcasting the number and control the display module 50 to stop displaying the number when a person approaches.

[0023] Among them, the circuit board of the key module 20 adopts a 16-key matrix key, and its row and column ports are connected to the GPIO digital IO port of the main control module 10. The main control module 10 detects the level state of each column port by scanning row by row, thereby determining the key information input by the key module 20, including numbers and control commands.

[0024] Specifically, the key module 20 is provided with a stop key, a confirmation key and several numeric keys. Several numeric keys, including numbers 0 to 9, are used to input numbers. The stop key is used to input a control command to stop broadcasting a number, and the confirmation key is used to input a control command to confirm a number. In actual applications, it may also include a volume increase key, a volume decrease key, a cancel key, a delete key, etc.

[0025] The voice module 30 has a preset voice file content built in, and its Rx / Tx port is connected to the UART serial port of the main control module 10. The main control module 10 sends a specified command to the voice module 30 through the UART, including a command to start playing a number. The voice module 30 then looks up the table to play the corresponding voice file content. When the voice module 30 receives a command to stop playing a number, it stops playing the number.

[0026] The display module 50 uses an OLED display screen. The SCL and SDA pins of the OLED display screen are connected to the I2C serial bus data port of the main control module 10. The main control module 10 sends display instructions and data, and the SSD1306 driver chip inside the OLED receives the instructions and writes data to the display memory to complete the display of graphics and text.

[0027] The proximity sensing module 40 uses an infrared ranging unit, an ultrasonic ranging unit, or a laser ranging unit to detect human body distance information, etc. The data pin of the proximity sensing module 40 is connected to the ADC analog input port of the main control module 10. Taking the infrared ranging unit as an example, during detection, the infrared ranging unit emits infrared rays, and the distance can be detected according to the received reflected signal, and then the analog signal is output to the main control module 10 through the ADC port.

[0028] The main control module 10 uses an Arduino single-chip microcomputer, and BMduino-UNO is used as the main control MCU. The GPIO port of the single-chip microcomputer is connected to each peripheral module, and data communication is realized by reading and writing IO levels. The single-chip microcomputer queries the status of each module through a loop and controls the operation of each module. The single-chip microcomputer uses interface protocols such as I2C, UART, ADC, etc. to drive peripherals, wherein the main control module 10 uses an I2C bus to realize connection and communication with the display module 50 and the key module 20.

[0029] The main control module 10 of the utility model controls the voice module 30 to play the number in a loop, and if the proximity sensing module 40 detects that the human body distance information is less than a set threshold, the voice module 30 is controlled to stop broadcasting the number. That is, when the user sees or hears the number and approaches, the main control module 10 automatically controls the voice module 30 to stop broadcasting the number, and also controls the display module 50 to stop displaying the number. Among them, the threshold can be a pre-set distance, which is set according to the actual situation to prevent false triggering.

[0030] In practical applications, the device of the utility model further includes a housing, and each module can be encapsulated in the housing, wherein the voice module 30 is installed on the top surface or side surface of the housing. The key module 20 is installed on the top surface or side surface of the housing to facilitate the staff to input numbers or control commands. The proximity sensing module 40 and the display module 50 are installed on the same side of the housing, that is, the proximity sensing module 40 and the display module 50 are both facing the user, which is convenient for the user to view the display module 50 and to detect whether the user is approaching.

[0031] Application Example 1

[0032] Taking the canteen meal pickup as an example, the device of the utility model is placed in the canteen meal pickup area, and the person picking up the meal has ordered the meal through the self-service ordering machine or the service staff and has taken the meal number.

[0033] When the meal is prepared, the waiter enters the meal number, for example 001, through the numeric keys of the key module 20; after the meal number is entered, press the confirmation key to confirm that the meal number has been entered. After the main control module 10 receives the meal number, it controls the voice module 30 to play the meal number in a loop, and the display module 50 displays the meal number, and the proximity sensing module 40 starts detection.

[0034] When the person who takes the food comes to take the food, he enters the detection area of ​​the proximity sensing module 40, and the proximity sensing module 40 detects that the user is approaching, and the main control module 10 controls the voice module 30 to broadcast that the food has been taken and stops the circular calling. Alternatively, the service staff can stop the circular voice broadcast by pressing the stop button.

[0035] After the voice announcement is finished, the display module 50 stops displaying the meal number synchronously, and the number calling device waits for the next use.

[0036] Application Example 2

[0037] Taking the example of picking up medicine in a hospital, close contact in a hospital poses special health risks. The device of the utility model is placed near the corridor of the hospital, and the patient has already picked up the number.

[0038] When the medicines are packaged, the service personnel enter the number, such as 001, through the numeric keys of the key module 20; after the number is entered, press the confirmation key to confirm that the number has been entered. After the main control module 10 receives the number, it controls the voice module 30 to play the number in a loop, and the display module 50 displays the number synchronously, and the proximity sensing module 40 starts detection.

[0039] When the patient comes to pick up medicine, he enters the detection area of ​​the proximity sensing module 40, and the proximity sensing module 40 detects that the user is approaching, and the main control module 10 controls the voice module 30 to broadcast that the medicine has been picked up and stop the cyclic calling. Alternatively, the service staff can stop the cyclic voice broadcast by pressing the stop button.

[0040] After the voice broadcast ends, the display module 50 stops displaying the number synchronously, and the number calling device waits for the next use.

[0041] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
