An electronic skipping rope control system which uses non-earthed contact electromagnetic wave communication according to an embodiment of the present invention is shown in
The single-wire non-earth two-way data transmission technology is used in the communication between the conductive skipping blanket and skipping rope handle. Its communication process will be described as follows:
1. Via the pin PA6, the main chip IC3 HT46R22 of the electronic skipping rope control device makes the pin P5.4 of the single chip IC1 SN8P2501 send out a square wave with frequency of 1 MHz, amplitude of 5V and duty ratio of 50%. If the pin PA6 of the single chip IC3 HT46R22 outputs a low level, the pin P5.14 of the single chip IC1 SN8P2501 also outputs a low level, without producing frequency. According to this procedure, a group of modulating AC signals will be produced when the pin PA6 of the single chip IC3 HT46R22 outputs high and low levels, preferably, the frequency of the signal is 1 MHz.
2. By means of the contact of the conductive skipping blanket CN 3 and J9-5P of the skipping rope handle, the AC signal makes the receiving amplifying circuit of the handle produce induced voltage. The induced voltage is then changed by a LC detection plastic circuit to be a signal level with amplitude of 5V.
The transceiver circuit arranged on the skipping rope handle:
The conductive rope is connected to the fifth pin of J9, and the port SINGIN is an input port. The port SINGIN receives the AC voltage signal of the skipping blanket. The AC voltage signal detected 1 MHz signal via L6, C64 and C65. The 1 MHz signal is amplified by Q26, Q24 and rectified by Q25, Q27 to form an electrical pulse signal and then transmitted to the pin PA5 of the single chip IC1 HT46R62.
The skipping rope handle sends corresponding electrical pulse signal back to the conductive skipping blanket immediately if it detects that the rope has rotated for one circle (if the three detecting points detects out a same input signal orderly, it means that the rope has rotated for one circle); otherwise no information will be sent back. The data sent out by the skipping rope handle will be received by the transmitting-receiving module of the skipping rope control device and then be processed and displayed.
The circuit principle of the skipping rope handle will be described as follows:
1. The single chip IC1 (HT46R62) arranged in the handle is equipped with a LCD display driver, which can display the visible contents such as score, consumed heat, counting of stopwatch and clock via the LCD CON2.
2. Five touch switches are arranged on the handle for different function settings.
3. Two AAA size batteries are provided for power supply, and the interface of power supply is J8.
4. Energy-saving technology is used. Only when the touch switch is pressed or the skipping rope is rotated will the handle be aroused. Otherwise the handle is normally on sleep mode. To save the quantity of electricity, the device Q23 is provided for causing the competition function to be not active in normal times (the pin PA1 of the single chip IC1 HT46R62 outputs high level to shut up the power supply of the receiving circuit).
5. The conductive sliding ring is provided for detecting the skipping for three times. The angle between each two adjacent contacts is 120 degrees, thereby avoiding producing inaccurate result of detecting.
6. Boost technique (U2, PT1301) is used for enhancing the transmittability of the skipping rope.
7. The handle uses buzzer LS2 to provide voice prompt about the operating state of the handle.
8. The memory (IC9, AT24C01) is provided for storing the identification numbers and scores.
9. The handle uses single-wire non-earth transmission technology to communicate with the conductive skipping blanket.
The circuit principle of the skipping rope control device will be described as follows:
1. The skipping rope control device uses five touch switches to achieve different function settings.
2. The power supply module is implemented by 6V5A lead-acid maintenance-free battery and DC24V. The IC2 TL494 is provided to achieve constant-current charge and floating charge. The bicolor LED LED1 is provided to indicate the state of charge.
3. A device U1 LM2575-ADJ is used as main power supply and outputs a voltage of 5V to the whole counting control system. When the output voltage of LM2575-ADJ is lower than 4.7V, the device N1B772 starts to work to enhance the output voltage, thereby ensuring that the operating voltage of the skipping rope control device is always more than 4.7V and then the skipping rope control device can operate stably.
4. The display screen is composed of nixie tubes. The single chip IC3 HT26R22 transfers the serial data into parallel data by 74HC595 and then drives the nixie tubes to display the contents such as score and time and so on.
5. The skipping rope control device uses active buzzer BZ1 to provide voice prompt about the system operating state.
6. The skipping rope control device uses single-wire non-earth transmission technology to communicate with the handle.
7. The skipping rope control device is capable of communicating with other control devices. A communication interface CN5 is provided for transmitting and receiving the data of the control device so as to display the same content.
8. The skipping rope control device is capable of controlling the next skipping rope control device by CN2.
9. The skipping rope control device is capable of being controlled by the preceding skipping rope control device via CN1.
In the system of the present invention, there may be included an operating console with which the skipping rope control devices can synchronize. The display and operation functions of this operating console will be described as follows:
1. The operating console uses five touch switches to achieve different function settings.
2. The power supply module is implemented by 12V5A lead-acid maintenance-free battery and DC24V. The IC2 TL494 is provided to achieve constant-current charge and floating charge. The bicolor LED LED1 is provided to indicate the state of charge.
3. The device U1 LM2575-ADJ is used for outputting a voltage of 10V to the nixie tube system. When the output voltage of LM2575-ADJ is lower than 9.5V, the device N1B772 starts to work to enhance the output voltage, thereby ensuring that the operating voltage of the skipping rope control device is always more than 9.5V and then the skipping rope control device can operate stably. The device IC1 7805 is used for providing a voltage of 5V to the control system.
4. The single chip IC3 HT26R22 transfers the serial data into parallel data by 74HC595 and then drives the nixie tubes to display the contents such as score and time and so on.
5. The operating console uses an active buzzer BZ1 to provide voice prompt about the system operating state.
6. The operating console uses CN2 to communicate with the skipping rope control device and maintains data synchronization with it.
In the embodiment which uses wireless communication modules to achieve communication, the skipping blanket has a plurality of contact-press type switches 57A (uniform matrix distribution on the skipping blanket) which is connected with the processor 51A. Every time the jumping person hits the ground, the electrical signal will be produced once, such process is one way of counting. The contact-press type switches 57A may be composed of the switches arranged on a FPC (flexible print board) of the keyboard or other similar products. Because the skipping rope also will contact and press the skipping blanket, the contact-press type switches in the skipping blanket cannot be arranged in a simple coordinated way, but need to assign a number or ID to each contact-press type switch and carry out a judgment as follows: only when the contact-press type switches which produce signal form a layout similar to the shape of the footprints can it be determined that a landing action occurs. And when the contact-press type switches which produce signal form a layout similar to the shape of the arc line, it can be determined that the rope has hit the skipping blanket. As a further preferable embodiment, can merely use the skipping blanket which is provided with multiple contact-press type switches to achieve the counting of rope skipping, by means of calculating and analyzing the switch signals produced when the rope hits the skipping blanket. In other words, only when the layout of the contact-press type switches which produce signals is similar to the path line of the rope contacting with the skipping blanket can the counting be carried out, and if it shows a shape of the footprints or others, no counting is carried out. In order to improve the detection precision of the counting of rope skipping, the distance between the contact-press type switches cannot be designed too large, and in order to reduce the cost, the contact-press type switches should not be provided too many. Preferably, the distance between the contact-press type switches may be arranged in a range from 1 cm to 5 cm. To simplify the circuit structure and reduce the manufacturing cost of the skipping blanket, the skipping blanket can be divided into two regions, one of which is provided as a landing area for the jumping person and the other is provided as a contacting area for the rope.
Because of the variety of the skipping competition and examination, the wireless communication mode for counting is achieved by the electromagnetic signals with frequency of 2.4 GHz, and the non-earthed contact single-line communication mode is achieved by the low-frequency and zero-distance electromagnetic wave communication with frequency from 800 KHz to 2 MHz. The former can be applied on fancy rope skipping game, such as a rope skipping like this: every time the jumping person jumps up, he/she need to rotating the rope for two circles, three circles, four circles or even more.
In another embodiment, only the wireless communication module is used and the skipping blanket is removed, that is, the counting result is produced by the skipping rope handle and then transmitted to the control device by the wireless communication module, and the landing of the jumper will not be counted. In still another embodiment, only the skipping blanket with contact-press type switches is used, that is, only the action of the rope hitting the skipping blanket will be counted without needing the counting function of the skipping rope handle (in such an embodiment, the count may be ended or be cumulative when the jumper pauses halfway, and these different functions can be realized by rewriting the programs of the micro-controllers or other similar chips).
In conclusion, with respect to the control device of the present invention, it can display the results of rope skipping in real time to the audiences and examiner by the display screen, due to its impartiality, it is conducive to the growth in popularity of rope skipping exercise, and it can be widely used in the rope skipping exercise, competition and examination; the skipping blanket and roller with supports provided by the control device are beneficial to storage and transport, thus it takes up less space; an independent operating console is provided, by means of the parallel connection of the communication ports, can use only one operating console to operate more than one control device simultaneously, thereby achieving synchronous control. With respect to the control system of the present invention, multiform communication modes can be used to carry out counting of the rope skipping, it has a simple structure and reliable function of counting and it is easy to be produced and installed.
