In this embodiment, the input and floor display module employs a74 LS148 chip; the input and floor display module is connected with the input end of the corresponding encoder through pressing down the keys corresponding to the floor number, one end of each key is grounded, the ground is connected with the input end of the corresponding encoder through pressing down the keys, namely the input logic is 0, and other switches which are not pressed down are connected with high potential, namely the input logic is 1. Eight input terminals of the 74LS30 are respectively connected with D0-D7 of the 74LS148, and an output terminal of the 74LS04 of the key detection part is connected with the LOAD terminal of the 74LS 160. The method for inputting the layer number is that keys corresponding to the layer number are pressed, one end of each key is grounded, the ground is connected with the input end of the corresponding encoder when the keys are pressed, logic 0 is input, and other switches which are not pressed are connected with high potential and input logic 1. Because 74LS148 is a priority encoder and is active at low level, the floor to be reached can be input and edited into binary code by the key, and the output is also active at low level, an inverter is connected to the output end of 74LS148 to change the code into the original code, the obtained original code is connected to the input end of 74LS160, and the key detection is carried out by using an eight-input NAND gate. We will always connect J1 to the active level, which means that when there is no other input signal, nand gate outputs 1, gets low level through inverter, 74160 sets number, gets 0, and when there is other input, the output is the floor pressed by the key due to the priority coding characteristic, and the floor selected by the key can be displayed through nixie tube.
And connecting the J1 end of the 74LS148 chip with an effective level, outputting 1 by the NAND gate when no input signal exists, obtaining a low level through the inverter, setting the number of the 74160 chip to be 0, and displaying the floor selected by the display key of the nixie tube.
In this embodiment, the floor comparison and elevator operation module preferably includes: a comparator 74LS85 and an up-down counter 74LS 190;
after a floor selection key is pressed, the binary code of the selected floor is input into A3A2A1A0 of a numerical comparator through the encoding of the 74LS 148; the output of the 74LS190 represents the current position of the elevator, the position is directly displayed through a nixie tube, the position is input to the end B3B2B1B0 and is compared with the key input code A3A2A1a0, if the position and the input end are equal, the output of the end a is 1, namely the output of the end B is high level, the allowed end of the 74LS190 enters a holding state, namely the elevator is in a waiting state, and meanwhile, a WAIT indicator light turns green;
when the floor where the 74190 output is located is higher than the floor where the key input is located, namely the output of the end a < b is 1, the end is connected with the addition and subtraction control D/U end of the 74LS190, the 74LS190 performs subtraction counting until the end a is equal to the floor where the key input is located, the output of the end a is 1, and the 74LS190 enters a holding state; similarly, the floor where the 74LS190 outputs is lower than the floor where the key is input, and the 74LS190 performs addition counting until the two are equal;
when the elevator is in a rising state, the three indicator lights are sequentially and circularly lightened upwards; when the elevator is in a descending state, the three indicator lights are sequentially and circularly lightened downwards, and when the elevator is in a waiting state, only the middle of the three indicator lights are lightened;
when the passenger and the elevator are on the same floor, the elevator indicating lamp displays the WAIT green lamp lighting state, and the elevator is in a passenger time friendly type at the moment and does not need to WAIT; when the passenger and the elevator are not on the same floor, the elevator indicating lamp displays a red lamp lighting state, and two red lamp states of UP and DOWN exist, so that the passenger is prompted to be located above or below the floor where the passenger is located in real time, and the red lamp indicates that the elevator is in a passenger time waiting type and needs to wait temporarily.
In a preferred embodiment, the A3 input of 74LS85 is connected to QD of floor display module 74LS 160; the a2 input of 74LS85 is connected to the QC of floor display module 74LS 160; the a1 input of 74LS85 is connected to QB of floor display module 74LS 160; the a0 input of 74LS85 is connected to QA of floor display module 74LS 160. The CLK-triggered terminal of 74LS190 is connected to the 74LS04 output terminal of the frequency divider block.
In a preferred embodiment, the frequency dividing module uses 1000Hz pulses as an input clock of the system, the toy uses a frequency dividing circuit to divide the frequency of the 1000Hz input pulses by 200, counts by two 74LS161 counters, connects the Qcc of a first 74LS161 to the clock input of a second 74LS161 to perform asynchronous counting, counts up by one in the second counter every time the first 74LS161 is full of 16 counts, counts 16 + 12+8 times to 200 times in total, and outputs of frequency division are sent to the 74LS190 through a not gate to perform elevator lifting control. 1000Hz pulse is used as the input clock of the system, however, if the 1000Hz pulse is directly connected to the pulse input end of the 74LS190, the circuit state is switched too fast, the flickering state of the lamp and the display output of the nixie tube cannot be seen clearly, so the frequency division circuit is selected for frequency division. The advantage of dividing the input pulse by 200 at 1000Hz is firstly that the period frequency is easy to calculate and the flashing of the lamp and the rising and falling of the elevator are relatively continuous. Two 74LS161 counters are used for counting, Qcc of a first chip 161 is connected to a clock input end of a second chip 161 for asynchronous counting, the second counter counts up by one every time the first chip 161 is full of 16, counting is totally carried out for 16 times by 12+8 times to 200 times, and the final frequency division output is sent to 74LS190 through a NOT gate for elevator lifting control.

when the comparator output a-b is 1, the inputs of the terminals S1 and S0 are both 1, so that the output is equal to the set-number input. The input terminal of A74LS04 is connected to the port of UP indicator light, the input terminal of B74LS04 is connected to the port of DOWN indicator light, and the CLK trigger terminal of 74LS194 is connected to the RCO port of frequency dividing module A74LS 161.
