Description

Electronic abacus

An abacus, especially an electronic abacus.

The abacus is a calculation tool used for arithmetic in Chinese culture. It has been circulated in the history of the Chinese cultural area for thousands of years. In recent years, although advanced tools such as electronic computers have matured and are more convenient to use, operating abacus is still widely taught and used as a skill and logic training tool.

An abacus contains multiple rows of abacus beads, and the relative position of the abacus beads in each row represents the corresponding value of the row of abacus beads. When performing operations and checking results, it must be observed and further checked by the human eye. Therefore, for example, in classroom teaching, if the number of students is large, the teacher must check the dialing results of each student one by one and confirm whether they are correct, which leads to a waste of time. In the existing digital abacus, some use the matrix scanning method designed by the keyboard switch concept to detect the switch status. This embodiment uses the vertical and horizontal two dimensions of the sender and receiver electronic signals to detect the switch status. It is interleaved on the switch, and the switch state is detected by the sending end and the receiving end in the vertical and horizontal dimensions. This method requires fixed length and width dimensions, and the matrix scanning circuit complexity is N*M+(N+M), including the sending end, the receiving end, and the interleaved switch nodes, which may invalidate the entire abacus due to any node failure ; In addition, some use electronic sensors such as light detection, electromagnetic induction, pressure change, etc. to detect the position of abacus beads. These methods are more complicated for switch design and state detection conditions, and environmental conditions are also likely to cause product stability Sexual issues, but also increase the cost of the burden. In addition, software is also used to design a virtual abacus in the computer system. The operator uses the computer keyboard, mouse, and touch to move the abacus on the abacus, and then can enter Calculate and learn. This method provides an interactive teaching material for learning abacus, which needs to be used on a computer. The place of use is limited and the dialing feel of a traditional abacus is lost, making it difficult to perform calculations quickly.

As mentioned above, the existing electronic abacus must use complicated circuit settings or sensors to determine the position of each abacus in multiple rows of abacus to read the value, and as long as part of the circuit or one of the sensors is damaged It will make the whole abacus unable to continue to be used, which will reduce the stability and durability of the product. The digital abacus provided by the application cannot provide the dialing feel and speed that the abacus should have. Therefore, the existing abacus or digital abacus is required Make further improvements.

In view of the fact that the existing traditional abacus must be checked by the human eye after the dialing calculation is completed, the inspection efficiency is low, and the existing digital abacus device has many inconveniences and deficiencies. The present invention provides an electronic abacus, which includes a base and at least one abacus. A gear module, a processing module and a communication module, the base has an insertion slot, the abacus gear module has a bracket unit, a first abacus unit and a circuit unit, the first abacus The unit is slidably arranged on the bracket unit and switched between a first position and a second position; the bracket unit is arranged in the socket and is assembled with the socket, the circuit unit and the bracket unit It is fixedly connected, and a corresponding impedance value is formed according to the position of the first bead unit. When the bracket unit is engaged with the insertion slot, the circuit unit and the processing module form an electrical connection, and the processing module detects the impedance value of the circuit unit and generates a numerical result information according to the impedance value.

Wherein, the circuit unit includes: an electrical connector having a first connection end and a second connection end; a first resistor electrically connected between the first connection end and the second connection end; a first The switch unit has a first switch state and a second switch state, the first switch unit is arranged in the length direction corresponding to the second position, and the first switch unit is connected in parallel with the first resistor; wherein, when the When the first bead unit is in the first position, the first bead unit does not trigger the first switch unit, so that the first switch unit is in the first switching state; when the first bead unit is in the second Position, the The first abacus unit triggers the first switch unit to make the first switch unit in the second switching state; wherein, the processing module determines the first arithmetic bead unit and the second switch unit according to different impedance values of the circuit unit. The abacus unit is in the first position and the second position, and then is converted into the reading value represented by the current position of the abacus gear module, and the numerical result information is generated accordingly.

That is to say, the processing module reads the impedance value of the circuit unit, generates different impedance values according to the different positions of the first bead unit, and further determines what the first bead unit represents in the specific state When multiple abacus gear modules are set in the slot, so that each abacus gear module represents a certain digit value, the processing module can judge different abacus gears according to different input pins For the number of digits represented by the module, read the value of the digit, and further generate a numerical result information based on the different digits and their values. In addition, the abacus gear module is arranged in the slot of the base in a snap-fitting manner, that is to say, the abacus gear module is pluggable and replaceable. When any occurrence of the abacus gear module occurs If it is damaged, the user can directly replace the abacus gear module without affecting the use of other abacus gear modules nearby.

To sum up, the electronic abacus of the present invention can not only provide the traditional abacus with the feel of calculating with the finger to move the bead, but also use the communication module to send the calculation result to an external electronic device, such as a smart A mobile phone or a computer for immediate review of the results. When teaching in the classroom, teachers can also know the calculation results of all students at once without checking them one by one, which effectively improves teaching efficiency. In addition, because the abacus gear module is replaceable, even if the circuit unit is damaged, the abacus gear module can be easily replaced and used continuously; further, when multiple abacus gear modules are set on the abacus Group to provide multi-digit calculations. Since each abacus gear module is electrically connected to the processing module and provides its own impedance value, when one of the abacus gear modules is damaged, it will not affect the other digits. For the detection of the abacus gear module, the user can also choose to remove the less used abacus gear module to replace the damaged one and continue to use it, thus improving the product stability and usability of the electronic abacus.

1 and 2A, the electronic abacus of the present invention includes a base 10, an abacus gear module 20, a processing module 30 and a communication module 40, the base has an insertion slot 11, the The abacus gear module has a bracket unit 21, a first abacus bead unit 221, and a circuit unit 23. The first abacus bead unit 221 is slidably disposed on the bracket unit 21 and is at a first position P1 and Switch between a second position P2; the bracket unit 21 is engaged with the insertion slot 11 of the base 10, the circuit unit 23 is fixed to the bracket unit 21, and a correspondence is formed according to the position of the first bead unit 221 The impedance value. When the bracket unit 21 is engaged with the socket 11, the circuit unit 23 is electrically connected to the processing module 30, and the processing module 30 detects the impedance value of the circuit unit 23 and generates a value according to the impedance value Results information. Please refer to FIGS. 2A, 2B and 8 together. In a first preferred embodiment of the present invention, the electrical The circuit unit 23 includes a first resistor R1 and a first switch unit S1 connected in parallel with the first resistor R1. The circuit unit 23 includes an electrical connection 231 having a first connection end and a first connection. There are two connecting ends, and the first resistor R1 is electrically connected between the first connecting end and the second connecting end, and the first switch unit S1 is arranged corresponding to the second position P2 in the length direction Y. The first switch unit S1 has a first switching state and a second switching state. Wherein, when the first bead unit 221 is at the first position P1, the first switch unit S1 is in the first switching state, and when the first bead unit 221 is at the second position P2, the first switch unit S1 is A switch unit S1 is in a second switching state.

In the following embodiments, the first switching state of the first switch unit S1 is an open circuit state, and the second switching state is a closed circuit state for example. Whether the first and second switching states of each switch unit are an open circuit or a closed circuit, respectively, can be designed according to the element selection of the switch unit, and both can achieve the effect of the present invention.

When the first switch unit S1 is in a closed state, the first switch unit S1 forms a short circuit at the opposite ends of the first resistor R1. At this time, the first connection terminal and the second connection terminal of the circuit unit 23 are short-circuited. When the first switch unit S1 is in an open state, the impedance value between the first connection end and the second connection end of the circuit unit 23 is the resistance value of the first resistor R1 r1. In this way, when the first bead unit 221 switches between the first position P1 and the second position P2, the impedance value of the circuit unit 23 will switch between r1Ω or 0Ω, and the processing module 30 According to the different impedance values of the circuit unit 23, it can be determined by looking up the table that the first bead unit 221 is at the first position P1 or the second position P2, and then converted into the current position of the first bead unit 221 The reading value represented by the position, and the result information of the value is generated based on it.

For example, FIG. 2A shows that the first bead unit 221 in the abacus gear module 20 is in the second position P2, and FIG. 2B shows that the first switch unit S1 in the circuit unit 23 corresponds to the first bead unit. The state of the position 221, FIGS. 3A and 3B show the relative state of the first bead unit 221 at the first position P1 and the circuit unit 23. When the first bead unit 221 is at the second position P2, the processing module 30 According to the impedance value of the circuit unit 23, it is determined that the numerical result information represented by the gear status of the electronic abacus at this time is 0Ω; as shown in FIG. 2B, when the first abacus unit 221 is at the first position P1, According to the impedance value of the circuit unit 23, the processing module 30 judges that the numerical result information represented by the gear status of the electronic abacus is 1 at this time.

Please refer to FIGS. 4A and 4B. In a second preferred embodiment of the present invention, the preferred arrangement structure of the abacus gear module 20 will be further described. Wherein, the support unit 21 includes a substrate 211, the substrate 211 has a first surface and a second surface opposite to each other, and has a through hole 2110 that communicates with the first surface and the second surface, and the second surface An abacus unit 221 abuts the first surface of the substrate 211. Further, the electrical connector 231 and the first resistor R1 of the circuit unit 23 are disposed on the second surface of the substrate 211, and the first switch unit S1 is disposed in the through hole 2110 and protrudes from the second surface. A surface, and the position of the first switch unit S1 corresponds to the second position P2 in the length direction Y. In this preferred embodiment, the first switch unit S1 is an elastic pressing switch element, that is to say, when the first bead unit 221 is in the second position P2, one of the first bead unit 221 The first bottom surface abuts and presses down the first switch unit S1 protruding from the first surface of the substrate 211, so that the first switch unit S1 is switched to the second switching state; when the first bead unit 221 moves to In the first position P1, the first switch unit S1 is no longer pressed by the first bead unit 221, and the first switch unit S1 rebounds and switches to the first switching state.

The carry system of an abacus is determined according to the number and arrangement of abacus beads in each row. Taking Fig. 1 of the present invention as an example, it is a decimal abacus with four beads on the top. When the abacus gear module 20 includes a plurality of bead units, the circuit unit 23 also includes a plurality of corresponding resistors and switch units to form different impedance values according to different positions of the abacus units. For the processing module 30 to read. The following will further illustrate the multiple application characteristics of the present invention with different embodiments.

Please also refer to FIGS. 3A, 3B and FIGS. 5A, 5B. In a third preferred embodiment of the present invention, the abacus gear module 20 further includes a second abacus unit 222. Bead unit 222 is also slidably disposed on the bracket unit 21 along the length direction Y, and can be switched between the second position P2 and a third position P3. In contrast, the circuit unit 23 further includes a second resistor R2 and a second switch unit S2. The second resistor R2 and the first resistor R1 are connected in series between the first connection terminal and the second connection terminal. ; The second switch unit S2 is connected in parallel with the second resistor R2, and also has a first switching state and a second switching state. Wherein, in this preferred embodiment, the resistance value of the second resistor R2 is different from the resistance value of the first resistor R1. For example, the resistance value of the first resistor R1 is r1Ω, and the resistance value of the second resistor R2 is r1Ω. The value is r2Ω.

The second switch unit S2 and the first switch unit S1 are disposed in a through hole 2110 of the substrate 211 and protrude from the first surface of the substrate 211, and the second switch unit S2 corresponds to the length direction Y The third position P3 is set.

Furthermore, when the first bead unit 221 is at the second position P2 and the second bead unit 222 is at the third position P3, the first bead unit 221 triggers the first switch unit S1, And the second bead unit 222 triggers the second switch unit S2, so that the first switch unit S1 is in the second switching state, and the second switch unit S2 is in the second switch state; when the first switch unit S2 is in the second switching state; When the unit 221 is at the first position P1 and the second bead unit 222 is at the third position P3, the first bead unit 221 does not trigger the first switch unit S1, and the second bead unit 222 triggers The second switch unit S2 makes the first switch unit S1 in the first switching state and the second switch unit S2 in the second switching state; when the first bead unit 221 is in the first position P1, And when the second bead unit 222 is in the second position P2, the second bead unit 222 triggers the first switch unit S1 but does not trigger the second switch unit S2, so that the first switch unit S1 is in the second position P2. Two switching states, and the second switch unit S2 is in the first switching state.

In short, the first switch is set corresponding to the second position P2, and the second switch unit S2 is set corresponding to the third position P3; when there is the first bead unit 221 at the second position P2 or When the second bead unit 222, the first switch unit S1 is in the second switching state, if not, the first switch unit S1 A switch unit S1 is in the first switching state; similarly, when the second bead unit 222 is at the third position P3, the second switch unit S2 is in the second switching state. If neither the first bead unit 221 or the second bead unit 222 is at the second position P2, the second switch is in the first switching state. And preferably, similar to the first switch unit S1, the first switching state of the second switch unit S2 is an open circuit state, and the second switching state is a closed circuit state.

In this way, according to the three different positions of the first bead unit 221 and the second bead unit 222 in the first position P1, the second position P2, and the third position P3, the first switch unit S1 and the second switch unit S2 produce different switching combinations. When the first bead unit 221 is at the first position P1 and the second bead unit 222 is at the second position P2, the second switch unit S2 is open and the first switch unit S1 is closed, the circuit The impedance value of the unit 23 is r2Ω; when the first bead unit 221 is at the first position P1 and the second bead unit 222 is at the third position P3, the first switch unit is in an open state but the second The switch unit S2 is in an open state, and the impedance value of the circuit unit 23 is r1Ω; when the first bead unit 221 is at the second position P2 and the second bead unit 222 is at the third position P3, the first bead unit 222 is at the third position P3. The switch unit S1 and the second switch unit S2 are both in a closed state, and the impedance value of the circuit unit 23 is 0Ω.

In this way, according to the three different positions of the first bead unit 221 and the second bead unit 222 in the first position P1, the second position P2, and the third position P3, the circuit unit 23 forms three types For different impedance values, the processing module 30 also judges that the first abacus bead unit 221 and the second abacus bead unit 222 are at the first position P1 and the second position according to the different impedance values of the circuit unit 23. P2 or the third position P3 is further converted into the reading value represented by the current position of the abacus gear module 20, and the numerical result information is generated accordingly. For example, when the impedance value is 0, the numerical result information is 0; when the impedance value is r1, the numerical result information is 1; when the impedance value is r2, the numerical result information is 2.

By analogy, when the abacus gear module 20 further includes a third bead unit 223 that switches between the third position P3 and a fourth position P4, the circuit unit 23 further includes a third switch unit S3 It is connected in series with a third resistor R3, the third resistor R3 is connected in series with the first resistor R1 and the second resistor R2, and the third switch unit S3 is connected in parallel with the third resistor R3. According to different position combinations of the first, second, and third bead units in the first to fourth positions, the first, second, and third switch units have different switch combinations, so that the circuit unit 23 generates Different impedance values. For example, when the first, second, and third bead units are respectively in the first, second, and third positions, the third switch unit is open in a first switching state, and the first and second bead units 2. The switch unit is a closed circuit, and the impedance of the circuit unit between the first connection end and the second connection end is the resistance value r3Ω of the third resistor R3.

It can be seen from the above description that when the abacus gear module 20 includes a plurality of bead units to provide more different numerical readings, the processing module 30 also detects the circuit of the abacus gear module 20 An impedance value between the first connection end and the second connection end of the unit 23 can determine all the readings of the abacus gear module 20. That is to say, under the framework of the present invention, the different carry system of the electronic abacus (for example, binary, quintal, and decimal) will not affect the processing module 30 to read the value of the abacus module 20 Processing complexity.

Furthermore, as shown in FIG. 1, when the electronic abacus includes a plurality of abacus gear modules 20, and each of the abacus gear modules 20 is arranged side by side in the insertion slot of the base 10 along a width direction X In 11, and the circuit unit of each abacus gear module 20 is electrically connected to the processing module 30 individually. That is to say, when the electronic abacus includes N abacus gear modules 30 to provide N-digit readings, the processing module 30 has a reading complexity of N, and the complexity and carry system are: The number of bead units of each abacus gear module 20 is irrelevant, so the calculation complexity of the processing module 30 is greatly reduced. In addition, no matter if any one of the switch units or the abacus position module 20 is damaged, it will not affect the operation of the other abacus position modules 20. It can be used continuously by removing or replacing the damaged abacus gear module 20, so the operation stability and durability of the electronic abacus are high.

In a fourth preferred embodiment of the present invention, the abacus gear module 20 also further includes the second bead unit 222, and the circuit unit 23 includes the second resistor R2 and the second switch unit S2. The arrangement of the second bead unit 222, the second resistor R2, and the second switch unit S2 is the same as that of the third preferred embodiment, and will not be repeated here. The difference is that the resistance value of the second resistor R2 is the same as the value of the first resistor R1. For example, the resistance values of the first resistor R1 and the second resistor R2 are both r1.

In the preferred embodiment, when the first bead unit 221 is at the second position P2 and the second bead unit 222 is at the third position P3, the first bead unit 221 triggers the first bead unit 221 Switch unit S1, and the second bead unit 222 triggers the second switch unit S2, so that the first switch unit S1 is in the second switching state, and the second switch unit S2 is in the second switching state; When the first bead unit 221 is at the first position P1 and the second bead unit 222 is at the third position P3, the second bead unit 222 triggers the second switch unit S2 to make the first switch unit S1 is in the first switching state, and the second switch unit S2 is in the second switching state; when the first bead unit 221 is in the first position P1, and the second bead unit 222 is in the second position At P2, neither the first bead unit 221 nor the second bead unit 222 triggers the first switch unit S1 or the second switch unit S2, so that the first switch unit S1 and the second switch unit S2 are The first switching state.

In this preferred embodiment, when the second bead unit 222 is at the second position P2, the second bead unit 222 will not trigger the first switch unit S1. That is to say, when the first and second bead units 221 and 222 are respectively at the first and second positions P1 and P2, the first and second switch units S1 and S2 are both in the first switching state, That is, they are all in an open state, and the impedance value of the circuit unit 23 is 2*r1Ω; when the first and second bead units 221 and 222 are respectively in the first and third positions P1 and P3, the first switch When the unit S1 is in the open state and the second switch unit S2 is in the closed state, the impedance value of the circuit unit 23 is r1Ω; when the first and second bead units 222 are in the second and third positions, the first and The second switch units S1 and S2 are both in the second switching state, that is, both are in the closed state, and the impedance value of the circuit unit 23 is 0Ω.

Therefore, when the processing module 30 determines that the impedance value of the circuit unit 23 is 2*r1Ω, the numerical result information is 2; when the impedance value of the circuit unit 23 is r1Ω, the numerical result information is 1; the circuit unit 23 When the impedance value of is 0Ω, the result information of the value is 0.

Please refer to FIGS. 6 and 7 together. In this preferred embodiment, in order to make the second bead unit 222 switch to the second position P2 without triggering the first switch unit S1, The bead unit 222 is improved. The second abacus bead unit 222 has a second bottom surface 2221, and the second abacus bead unit 222 faces the second bottom surface 2221 toward the first surface of the substrate 211, and the second bottom surface 2221 is concavely formed along the A second groove 2222 extending in the length direction Y; wherein, the second groove 2222 of the second bead unit 222 and the first switch unit S1 correspond to each other in the width direction X, and the second groove 2222 The second switch unit S2 is offset from each other in the width direction X. In this way, when the second bead unit 222 is at the second position P2, the first switch unit S1 is accommodated in the second groove 2222.

That is to say, when the second bead unit 222 is at the third position P3, since the second groove 2222 and the second switch unit S2 are staggered in the width direction X, the second bottom surface 2221 abuts against the The first surface of the substrate 211 triggers the second switch unit S2 so that the second switch unit S2 is in the second switching state; when the second bead unit 222 is in the second position P2, due to the second groove The slot 2222 corresponds to the first switch unit S1 in the width direction X. The first switch unit S1 will be just received in the second groove 2222 without being triggered by the second bottom surface 2221. The first switch unit S1 is maintained in the first switching state.

In short, the first switch unit S1 and the second switch unit S2 are arranged in a "one left and one right" manner, and the second groove 2222 on the bottom surface of the second bead unit 222 is arranged on the left side. Therefore, when the second bead unit 222 is in the second position P2, the second bottom surface 2221 of the second bead unit 222 will not trigger the first switch unit S1.

Please continue to refer to FIG. 7. Under the same inventive concept, when the abacus gear module 20 further includes the third bead unit 223, a third bottom surface of the third bead unit 223 also has a The groove of the third bead unit 223 and the third switch unit S3 are staggered in the width direction X, and correspond to each other in the width direction X of the second switch unit S2. That is to say, the first switch unit S1 and the second switch unit S2 are arranged in a "one left and one right" manner, and the grooves of the second bead unit 222 and the third bead unit 223 are "One right and one left" setting. When the third bead unit 223 is at the third position P3, the third bead unit 223 will not switch the second switch unit S2 to the second switching state.

Please refer to FIG. 8 to FIG. 10. In a fifth preferred embodiment of the present invention, the combination of the abacus gear module 20 and the base 10 will be further described. The base plate 211 of the support unit 21 has a first end and a second end opposite to each other along the length direction Y, and the insertion groove 11 of the base 10 has a first side and a second side extending from the length direction Y . Wherein, the base plate 211 protrudes outward from the second surface at the first end to form an engaging hook portion 212. The engaging hook portion 212 first extends away from the second surface in a height direction Z, and then extends along the The longitudinal direction Y extends toward the second end; and the insertion groove 11 forms an engaging recess 111 on the first side, and the engaging hook portion 212 of the base plate 211 is in position with the engaging recess 111 of the insertion groove 11 And the shape matches each other.

In addition, the electrical connector 231 of the circuit unit 23 is a first pin connector, and is disposed on the second surface of the second end of the substrate 211. The base 10 further includes a second pin connector 112 disposed on the second side of the insertion slot 11. The first pin connector of the circuit unit 23 and the second pin connector 112 of the base 10 cooperate with each other, and the first pin connector and the second pin connector 112 of the base 10 are along the length direction Y During insertion, the engaging hook portion 212 of the base plate 211 engages with the engaging recess 111 of the base 10. Since the circuit unit 23 is fixed on the second surface of the first end of the bracket unit 21, when the electrical connector 231 of the circuit unit 23 is connected to the second pin connector 112 provided on the second side of the socket 11 The electrical connection is formed, and the fixing of the bracket unit 21 is also formed. In this way, the bracket unit 21 The first end of the base plate 211, the base 10 and the second end are all fixed to the insertion slot 11, and the movement of the support unit 21 in the length direction Y, width direction X and height direction Z is restricted, so that The support unit 21 is stably arranged in the base 10. The user can easily remove the abacus gear module 20 for further replacement by pulling out the support unit 21 along the length direction Y toward the second end of the base plate 211. The second pin connector 112 is further electrically connected to the processing module 30 to form an electrical connection between the circuit unit 23 and the processing module 30.
