[0046] Take the circuit diagram of a transmitter as an example, which is a Proteus simulation diagram. The transmitter number is input through the 3×4 matrix keyboard, and the transmitter number is displayed on the digital tube. The 51 single-chip microcomputer controls the switching of the transmitter through the digital output segment value displayed on the digital tube.

[0047] 1) Keyboard module

[0048] The keyboard module includes 0-9 numeric keys, RST (cancel key, corresponding to SW1) and on / off key SW2. 0-9 numeric keys and RST (cancel key) are BUTTON buttons. Since the business input and output ports are two audio lines, the on / off key switch SW2 is a double switch to control the on and off of the business port output. Figure 2 , Figure 3 , Figure 4 shown.

[0049] like Figure 3 , the specific connection relationship of the 0-9 numeric keys is:

[0050] The P10~P13 and P15~P17 terminals of the 51 single-chip microcomputer constitute the 0-9 numeric keys, and the specific layout is as follows:

[0051] The P10 terminal of the 51 single-chip computer is connected to the 3-digit key and the 7-digit key respectively between the P17 terminal and the P16 terminal;

[0052] The P11 terminal of the 51 single-chip computer is connected to the 2-digit key and the 6-digit key respectively between the P17 terminal and the P16 terminal;

[0053] The P12 terminal of the 51 single-chip computer is connected to the P17 terminal, the P16 terminal, and the P15 terminal respectively to connect the 1 numeric key, the 5 numeric key, and the 9 numeric key;

[0054] The P13 terminal of the 51 single-chip computer is connected to the P17 terminal, the P16 terminal, and the P15 terminal respectively to connect the 0 number key, the 4 number key, and the 8 number key;

[0055] Connect RST (cancel key) between terminal 22 of 51 MCU and ground wire;

[0056] The 0-9 numeric keys and RST (cancel key) are all buttons;

[0057] RST (cancel key SW1) is a push button switch, one end of RST (cancel key SW1) is connected to terminal 22 of 51 single chip microcomputer, and the other end is grounded;

[0058] The on / off key is a double switch SW2, and the model of SW2 is SW-DPST. The two pins at one end of the double switch SW2 are respectively connected to the E20 terminal and the E30 terminal of the 51 single-chip microcomputer, and the two pins at the other end are respectively connected to the E21 terminal and the E31 terminal of the 51 single-chip microcomputer.

[0059] 2) Display module

[0060] like Figure 5The display module includes a display screen for displaying the transmitter number input by the keyboard, an LED transmitting light (Jxx) for displaying the transmitter channel, and an LED business light (13107) for displaying the business port channel. The display screen is a 7-segment digital tube, which is connected to the E10 terminal to the E17 terminal of the 51 single-chip computer through the resistor RP1. The resistor model is RESPACK-8. LED transmitting light ( Figure 6 Indicated by Jxx, for example, J1~J48) one end is connected to the digital power supply and the other end is connected to the corresponding port of the 4067 electronic switch chip; the LED business light (13107) is connected to the E31 terminal and E21 terminal of the 51 microcontroller.

[0061] In this patent, a 7-segment digital tube is used as a display screen to display the transmitter number input by the keyboard. The LED light (Jxx) represents the path of the transmitter, and the LED (13107) represents the path of the service port. When the LED light is on, it means that the circuit is connected, that is, the transmitter is connected to the service port. Figure 5 , Figure 6 shown.

[0062] 3) Switching module

[0063] The switching module includes a 4067 electronic switch chip and a 4051 electronic switch chip. The 4 input pins of the 4067 electronic switch chip are connected to the E1~ terminal to the E4 terminal of the 51 single-chip microcomputer. The 3 input pins of the 4051 electronic switch chip (corresponding to input pin 11 to input pin 9) are connected to the E5 terminal to the E7 terminal of the 51 single-chip microcomputer. The output pins of the 4051 electronic switch chip are connected to the E20 terminal or the E30 terminal of the 51 single-chip microcomputer. The E20 terminal and the E30 terminal of the 51 single-chip microcomputer are connected to the two audio lines of the service port. There are two groups of audio transmission lines.

[0064] There are three 4067 electronic switch chips. After the three 4067 electronic switch chips are cascaded, they correspond to one 4051 electronic switch chip. The three 4067 electronic switch chips and the corresponding 4051 electronic switch chips form a set of audio transmission lines. The Q1 end of the 4067 electronic switch chip at the front stage is connected to the audio line of the transmitter.

[0065] Since the 4067 electronic switch chip and the 4051 electronic switch chip can transmit audio signals, and the 4067 electronic switch chip has the function of selecting one channel from 16 channels, cascading three 4067 electronic switch chips can form a function of selecting one channel from 48 channels, and finally use the 4051 electronic switch chip to control the output of a certain channel of the 48 channels. Since there are two transmission lines for audio signals, two input and output ports are required. The input ports are the two Q1 in the figure, which are connected to the two audio lines of the transmitter, and the output ports are E20 and E30 in the figure, which are connected to the two audio lines of the business port, as shown below Figure 7shown.

[0066] In addition, a crystal X1 is connected between pins 19 and 18 of the 51 microcontroller. Pin 19 of the 51 microcontroller is connected to the digital power supply through capacitor C1, and pin 18 is connected to the digital power supply through capacitor C2.

[0067] The overall operation effect is as follows Figure 8 For example, when service 13107 selects transmitter No. 20, the display shows that the transmitter number is 20, and the on / off key SW2 double switch is turned on, and transmitter No. 20 J20 is connected to 13107, and the green light is on.

[0068] The effect diagram of the switching disk for 8 transmitters is as follows, and the same applies to 47 transmitters. Fig. 9 The simulation circuit diagram of 2 transmitters is as follows. The same is true for 47 transmitters. One more 51 single-chip microcomputer is added, the keyboard module is redesigned with 10-19 numeric keys, a set of display screens, LED business lights (transmitter 20, transmitter 21), and resistor RP2 are added to the display module, SW3 is added to the cancel key, and SW4 is added to the on / off key.
