The circular electronic watch has 72 circular holes with the same shape, and the circular holes are divided into 60 holes for scoring and 12 holes for timing. One small ball is embedded in each small ball, when the set time is up, the small balls in the corresponding small holes are displayed in the circular holes towards the left, and the rest small balls are placed on the right and cannot be displayed in the circular holes. The 60 scored circular holes are arranged outside the circular ring, the 12 timed circular holes are arranged inside the circular ring, and the user can read the time according to the position state of the small ball.

The second pulse can be generated by a second pulse generating circuit in the timing circuit, and the second pulse signal is input to a second counting circuit to count the seconds. When sixty seconds have elapsed, that is, when the count reaches sixty, recounting is started and a carry pulse is generated, the carry pulse indicates a time of one minute, the time pulse indicating one minute is input to the sub-count circuit, counting is started by the sub-count circuit, and when the sub-count circuit counts sixty numbers, a carry pulse of the sub-count circuit is generated, and the sub-count circuit starts counting. The state of 60 small balls is controlled by the branch circuit, so that the display of minutes and the change thereof are realized. The position of the 12 small balls is controlled by a timing circuit, and the display of the hour and the change thereof are displayed. Furthermore, the counting change of minutes and hours can be changed by the correcting circuit and the time correcting circuit.

The second pulse generating circuit in the timing circuit is composed of a series of circuits taking 4.194304HZ crystal oscillators and 5512F chips as cores and a frequency doubling circuit consisting of CD4069 and CD 4011. The 4.194304HZ crystal oscillator generates oscillation, a series of circuits taking the 5512F chip as a core generate 0.5HZ pulse signals, and the pulse signals with the frequency of 1HZ can be output through the frequency doubling circuit. The pulse signal is the time reference second pulse of the timing circuit, and the second pulse is input into the second counting circuit to count the time, so that the novel electronic watch can normally and accurately run.

The second counting circuit in the timing circuit is formed by connecting two 74LS160 counters in series to form a sexagesimal counter, the first 74LS160 counter serves as a decimal counter, the second 74LS160 counter serves as a sexagesimal counter, when the first 74LS160 counter counts ten times, the first counter carries the second counter, the second counter is increased by one, and when the second 74LS160 counter counts 6, the two counters are cleared at the same time, so that the function of automatically counting seconds by the timing device is realized.

The sub-counting circuit in the timing circuit is formed by connecting two 74LS160 counters in series to form a sexagesimal counter, the first 74LS160 counter is a decimal counter, the second 74LS160 counter is a sexagesimal counter, when the first 74LS160 counter is full of ten, the first counter carries to the second counter, so that the second counter is increased by one, and when the second 74LS160 counter is counted to 6, the two counters are cleared at the same time, so that the automatic scoring function of the timing device is realized.

The timing circuit in the timing circuit is formed by connecting two 74LS160 counters in series to form a one-hundred-system counter, the first 74LS160 counter is a decimal counter, and the second 74LS160 counter is also a decimal counter. When the output end is 1010, the next state code of the circuit will generate an asynchronous zero setting signal, and is simultaneously applied to the two 74LS160 counters, and when the next counting pulse, i.e. the 12 th input pulse arrives, the counters will start to count again, thereby forming a twelve-system counter and realizing the timing function of the timing device.

The time display circuit in the time display circuit consists of a 74HC154 type 4-16 decoder and 3 exclusive-OR gates. The chip 74HC154 type 4-16 decoder is connected with input pins IN of ten relay modules for controlling the state of the small ball, 3 chips are connected with an XOR gate connected with the decoder and input pins IN of two relay modules for controlling the position state of the small ball, the 74HC154 type 4-16 decoder is connected with two chips 74LS160 counters IN a timing counting circuit, the 74HC154 type 4-16 decoder and the 3 XOR gates are controlled by the two chips 74LS160 counters, the state of the relay modules is changed according to a certain control rule, and then the state of the small ball is changed.

The sub-display circuit in the time display circuit is formed by arranging six 74HC154 type 4-16 decoders, each 74HC154 type 4-16 decoder is directly connected with ten relay modules, the state of ten small balls is further controlled, and each small ball represents one minute. And an additional 74HC154 type 4-16 decoder at the leftmost end is connected with the input end of a second-stage counter in the sub-counting circuit and respectively controls the right six 74HC154 type 4-16 decoders to be switched on and switched off according to a certain rule. The right six 74HC154 4-16 decoders are directly connected to the first stage counter in the sub-counting circuit, so that different minute times can be realized to put the ball in different states.

The timing device should have separate calibration and time calibration functions, so the invention needs to be added with the function of time calibration. The time correction circuit is formed by connecting a time correction mechanical key, a time correction resistor R1 and a time correction 74LS136 exclusive-OR gate to form a time correction circuit, and a time correction mechanical key, a time correction resistor R2 and a time correction 74LS136 exclusive-OR gate to form a time correction circuit. The output end of 74LS136 in the branch calibration circuit is connected with the CLK clock signal of the branch location circuit, one end of the input end is connected with the key control circuit, and the other end is connected with the branch location mark. When the key is released, the input of one end is high level, and the output of the exclusive-OR gate is low level because the sub-potential mark is low level. When the key is pressed, one section of input is low level, and the output of the exclusive-or gate is high level due to the fact that the sub-potential mark is low level. The exclusive-or gate is connected with the clock signal of the sub-counter, and the sub-counter is added with one by giving a rising edge to the clock signal of the sub-counter, so that the function of timing is finished. The principle of the time calibration circuit should be similar to that of the branch calibration circuit. In this way, the clock signal is subjected to level inversion once, and the count values of the corresponding sub-counting circuit and the corresponding time-counting circuit are increased by one, so that the change of minute counting and hour counting is adjusted.

By adopting the technical scheme, the time is displayed by adopting the method for changing the position state of the small ball, and the electric energy is consumed only when the small ball is driven to switch the state, so that the power consumption of the electronic watch on the display function can be saved to the greatest extent. In addition, the small ball for expressing time of the electronic watch is added with the fluorescent material, the small ball for expressing corresponding digital decoration of twelve hours and the small ball for expressing corresponding numbers of minutes are arranged on the surface of the electronic watch, so that the electronic watch not only can be used as a household decoration, but also can be used for timing, and the defect that the household decoration only has a decoration function and the electronic watch is not beautiful is effectively overcome. Due to the use of small beads of fluorescent material, light pollution can be effectively reduced and better readings can be taken at night. The invention has reasonable design and the advantages.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings.

As shown in fig. 1, the electronic watch is circular, in which 60 small balls 1 for scoring and 12 small balls 2 for timing are embedded, and a little decoration can be added at the dial 3. As shown in the second drawing, the second drawing is a state control diagram of the small ball, 4 is the small ball with magnetism, 5 is an electromagnet, 11 is a straight rod with conductivity and connected with the anode of a power supply 8, 10 is a relay module, 6 and 7 are the only conductive structures which can be in contact with the straight rod 11, and 9 is a bearing which facilitates the rotation of the straight rod and can reduce the friction when the straight rod rotates. IN normal operation, a signal is input to IN of the relay module 10 by a sub-counting circuit or a time-counting circuit. IN the relay module, a low level is given to an IN pin, an NC end can be disconnected, an NO end can be closed, a high level is given to the IN pin, the NC end can be closed, and the NO end can be disconnected. When the time reaches a certain moment, when the small ball is required to be beaten to the left, the corresponding counting circuit can give a low level to the IN pin, when the small ball is positioned at the position of the right 7, the small ball can be connected with the circuit above to form a passage, due to the action of the electromagnet, the small ball is subjected to a force towards the left, when the small ball touches the contact part 6, another passage can be formed, the electromagnet continues to act for a short time, when the small ball passes through a left balance point, namely the leftmost end of the contact part 6, the circuit is disconnected again, and the small ball is contacted with the left 7 due to the action of gravity. After waiting for a while, the signal at N will change, the levels at the two ends of NO and NC will swap, resulting in another current path being formed, and the electromagnet on the right will also pull the ball to perform the same process. Therefore, the state of the small ball can be correspondingly changed according to the signal given by the time counting module, and the function of time display is further realized.

Fig. 3 is a schematic configuration of a control circuit, which includes a second pulse generating circuit, a second counting circuit, a minute counting circuit, a timer counting circuit, a ball control circuit, and a time correcting circuit.

As shown in fig. 3, the general structure of the control circuit includes a second pulse generating circuit, a second counting circuit, a minute counting circuit, a time counting circuit, a ball control circuit, and a time correction circuit.

As shown in fig. 4, the pulse-per-second generating circuit is composed of a series of circuits 12 using 4.194304HZ crystal oscillator and 5512F chip as core and a frequency doubling circuit 13 composed of CD4069 on CD4011, and can output a pulse signal with a frequency of 1HZ, which is the time-based pulse-per-second of the timer circuit, and the pulse-per-second is input to the second counting circuit to count the time.

As shown in fig. 5, the second counting circuit 14 in the timer circuit is formed by connecting two 74LS160 counters in series to form a sexagesimal counter, the first 74LS160 counter is a decimal counter, the second 74LS160 counter is a sexagesimal counter, the second 74LS160 counter automatically increments by 1 whenever the first 74LS160 counter counts up to ten, and the two counters are cleared simultaneously when the second 74LS160 counter counts up to 6, thereby continuously circulating, and realizing the function of automatically counting seconds by the electronic watch.

As shown in fig. 6, the sub-counting circuit 15 is a sexagesimal counter formed by connecting two pieces of 74LS160 counters together, and the carry terminal of the first piece of 74LS160 counter is connected to the second piece of 74LS160 counter. When the first slice 74LS160 counter counts up to ten, the second slice 74LS160 counter automatically counts up 1, when the second slice 74LS160 counter counts up to 6, the two counters are cleared simultaneously, the counter can count continuously, and the function of automatic electronic watch scoring is realized. Also connected to the sub-counting circuit are seven 74HC154 decoders. Directly connected to the sub-counting circuit is a first 74HC154 decoder for controlling the rear six 74HC154 decoders. The first ten bits of the decoder are output ends and are used for being connected with an IN pin of a relay module for controlling and displaying the small balls, and further controlling the position state of each small ball IN the sixty small balls. Therefore, the function of displaying the watch minute time is realized.

As shown in fig. 7, the timer circuit 16 is a twelve-valued timer circuit, and two 74LS160 counters are connected in series to form a counter, where we use the status code of the timer circuit to generate an asynchronous zero-setting signal, i.e. the feature of automatic zero-setting when the count value reaches 1010. In order to realize the twelve-system counter, 3 exclusive-or gates are additionally added on the circuit design, so that the twelve-system counter is formed, and the hour counting function of the watch is realized. The display circuit connected to the time counting circuit is composed of a 74HC154 type 4-16 decoder and 3 exclusive OR gates. The 74HC154 decoder is connected with ten relay modules for controlling and displaying the small ball state, and the three exclusive-OR gates are connected with two relay modules for controlling and displaying the small ball state, so as to control the position state information of twelve small balls together, thereby realizing the display function of the watch hour time.

The distribution circuit 17 and the timing circuit 18 are shown in fig. 8, and include a mechanical timing button, a resistor R1, a resistor R2, and a 74LS136 xor gate. The output end of 74LS136 in the branch calibration circuit is connected with the CLK clock signal of the branch location circuit, one end of the input end is connected with the key control circuit, and the other end is connected with the branch location mark. When the key is released, the input of one end is high level, and the output of the exclusive-OR gate is low level because the sub-potential mark is low level. When the key is pressed, the input of one end is low level, and the output of the exclusive-or gate is high level because the sub-potential mark is low level. The exclusive-or gate is connected with the clock signal of the sub-counter, and the sub-counter is added with one by giving a rising edge to the clock signal of the sub-counter, so that the function of timing is finished. The principle of the time calibration circuit should be similar to that of the branch calibration circuit. In this way, the clock signal is subjected to level inversion once, and the count values of the corresponding sub-counting circuit and the corresponding time-counting circuit are increased by one, so that the change of minute counting and hour counting is adjusted.

As shown in fig. 3, the basic flow of the control circuit is: first, the second pulse generating circuit generates a second pulse having a frequency of 1HZ, and the second pulse is input to the second counting circuit 14 to count seconds. When the second count reaches 60, a carry pulse is generated in the minute counting circuit 15, so that the minute counting value in the minute counting circuit 15 is incremented by one. When the minute count reaches 60, a carry pulse is generated to the counter circuit 16, so that the count value in the counter circuit is incremented by one. The sub-counting circuit converts the counting value into the state control of sixty small ball displays controlled by the relay module through a 74HC154 type decoder. The timing and counting circuit drives 12 relay modules to control the state of the small ball display structure, so that the change of hour time is displayed. The change in the count of hours and minutes is adjusted by adjusting the clock pulses by the correction circuit 17 and the timing circuit 18.
