Description

Communication transmitter/receiver capable of inputting unique identification ID for communication by counting method

Technical Field

When a plurality of devices are connected to each other by communication, each communication transceiver has a unique device Identification (ID) code for identifying itself by other devices, and the microcontroller of each communication device selects only information matching its own ID from information entered through the communication line by using the ID to perform communication. The ID code is also called an Address (Address). The present invention relates to a communication device in which a method of simply inputting an inherent identification ID by a button or a switch according to the principle of a counter method is applied to a communication device or a device to be controlled by communication.

Background

Communication devices are arranged in a multipoint manner in RS-485 communication or the like, a device ID code to be communicated is transmitted together with Data, and after each communication device analyzes a communication packet, only packet Data corresponding to its own ID is taken and then selectively operated.

Wireless communication such as ZigBee or Zwave determines whether Data transmitted to each communication device is transmitted to the communication device in the same manner. DALI or DMX512, which controls a plurality of lights by wired communication, also has a means of inputting an ID corresponding to each Address, and mainly inputs a switch having a DIP switch or a dedicated display device.

ZigBee, ZWave, and other wireless communication technologies can be regarded as communication IDs, and lighting control devices such as DMX512 and DALI controlled by wired communication can be regarded as control target IDs. Since a communication device is a part of the configuration of a device controlled by communication, such as a lighting control device such as DMX512 or DALI, the actual control target ID may be regarded as the communication ID.

The most common way to enter a communication ID or address is to use DIP switches that combine a plurality of single switches into one element. Each single switch is used to receive the state of the DIP switch as the communication ID at the microcontroller after matching the bins for the on/off state combinations.

There is also a digital band switch in which a plurality of toggle switches are connected to function similarly to a DIP switch, and a communication ID-related input value corresponding to the degree of rotation is input as an ID.

When other special devices for inputting an ID are used, a wireless communication device is used, which is applicable to UART, SPI, I2C, USB, Wi-Fi, bluetooth, ZigBee, and various other microcontrollers, and an ID value acquired from the special device is input by communication and used as an ID.

The input device of other special equipment for ID input can input ID through a DIP switch or a combination of a plurality of toggle switches or band switches, or can input ID through a keyboard matched with decimal numbers or sixteen-numbered numbers, and can also be a touch panel.

And other digits, such as decimal or hexadecimal, may be input according to inherent setting values of the device, such as the operation mode, instead of corresponding to the ID or address, and may include an LED, an LCD, and other display devices displaying the current input state.

It is also possible to use a device having UP and Down switches, increasing or decreasing the number of switch bits according to the number of pressing the switch, and displaying the value on a 7-segment display device to receive an ID input. It is also possible to implement it on the communication device itself or on the device itself controlled by the communication and to receive the entered values on a device separately connected in this way.

The input value may be input by a program driven on an information device such as a PC, a smart phone, or a touch panel, and the result may be input by connecting a device capable of communicating with a USB, a UART, or another microcontroller to transmit an ID, or the ID may be input by communicating with a microcontroller using a wireless communication device such as Wi-Fi, IoT, ZigBee, or bluetooth.

However, these various input devices are relatively complicated and expensive, and sometimes have a problem of difficulty in maintenance due to a problem of conversion with binary digits. The DIP switch elements are a set of a plurality of single switches, and power consumption due to each bias current is large.

To increase or decrease the bit value by using the two switches of Up and Down, it is complicated to have at least two switches and to have 7-stages capable of indicating the increase or decrease state.

When switches whose number of bits is changed in order to input a bit value corresponding to each bit value according to the length of the ID are used, if a plurality of switches are used, the problem of occupying a very small space in communication equipment is likely to arise, and if all of the plurality of switch values are input, the problem of limiting the input conditions of the microcontroller is caused.

Disclosure of Invention

Technical problem

The conventional input identification ID of a communication device or a device controlled by communication is a method in which an input of a DIP switch, a rotary switch, or a plurality of selector switches is received by an input terminal of a microcontroller, or a 7-segment display device and a switch for changing the number of digits such as UP and Down are input, or a communication function with a dedicated ID, an input device, a PC, a smart phone, a tablet, a smart pad, or a touch input device is input through a communication terminal of the microcontroller.

The invention provides a method which occupies less space, has diversified system design, low power consumption and economy compared with the prior mode when the communication ID is input to the microcontroller and confirmed by the communication equipment which needs the inherent ID or equipment controlled by the communication.

Technical scheme

The following device refers to a part of a circuit configuration of a communication device or a device controlled by communication, and may be an external module to be connected. According to the preferred embodiment, it is most preferred that the microcontroller, which plays a major role in the communication device or the device controlled by the communication, is ported with the form of a switch and an LED. Therefore, the so-called device can be solved as a part of the configuration of the device as described above, and is not independent from the communication device or the device controlled by the communication.

The main functions of a device controlled by communication are usually performed by a microcontroller, which usually comprises the functions of a communication device and may also perform control functions, so that a so-called communication device also comprises a device controlled by communication.

The present invention enables means of finger input. Touch-sensitive input means on a touch sensor or a touch screen can also be used in communication devices that use mainly finger-pressed push-button switches and that necessarily use the touch sensor or touch screen.

Even if one "bit number input means" is used, two may be enabled for other purposes. For example, when a signal for starting to input an ID or requesting to display an input ID is input instead of inputting an actual ID value, the input may be performed by the second "digit number input means" separately or may be performed by one "digit number input means" together.

The switch signal or touch signal of the "bit number input means" is used to input other lines on which the input of the pressed or touched state is received to process information. Hereinafter, when the switch is pressed or touched, it is referred to as "ON" of the "digit number input means", and when the switch is released or the touch is released, it is referred to as "OFF" of the "digit number input means".

The "digit number input means" is usually connected to the input of the microcontroller, so that the microcontroller recognizes "ON/OFF" and counts the number of times of the switching. The time required for pressing and releasing or the time which does not press for a certain time and passes is calculated and used as the main input information. For this purpose, a timer is provided on a line or microcontroller connected to the "digit input means". The timer is used for calculating the conversion time of the input state value of the digit input means, and the circuit or the microcontroller grasps the state that the input state of the digit input means is not changed and kept within a certain time.

The digit input means may repeatedly input digits within a predetermined time, may pause for a predetermined time, or may hold the pressed state for a predetermined time or more, thereby changing the number of input ID digits. As described above, the state is maintained for a predetermined time or more, but a method is required for informing the input person that the predetermined time has elapsed.

The time can be informed whether the time is over by using the LED lighting state or a visual panel or a screen display or a buzzing sound of a sound generating device. This means is an "information display device". The "information display device" may be used as means for displaying the number of input IDs, for example, by displaying each digit coefficient of an ID value by the number of repetitions of LED lighting, and displaying the input IDs by changing the number of digits without displaying or displaying them distinctively for a certain period of time.

When the communication device itself has a touch screen or a plate or other LCD, OLED or other visual display device, the coefficient value can be directly displayed on the screen by decimal number or sixteen-numbered number without repeating the number of times.

When a coefficient of 0 to 9 in a certain bit value of an ID is inputted by a specific state repetition number of the 'digit input means' and a coefficient of the next digit is inputted in a pause period of a certain time (the condition is displayed by an LED when the time is out), a calculation part for calculating the ID by using the number of the digit pause periods and the coefficient between the pause periods on a line or a microcontroller connected with the input of the calculation part is required. If the microcontroller is used, the operation function of the microcontroller is applied for operation.

The ID may be displayed as a hexadecimal number instead of a decimal number, and the ID may be input based on each digit. In this case, the coefficients are not 0 to 9 but 0X0 to 0F.

The calculated ID is stored in an SRAM, an EEPROM, a flash memory, or other nonvolatile storage device having a secondary battery, and can be read again at the time of initialization as an ID application even if power is off. Non-volatile memory space internal to the microcontroller may also be applied, and separately connected non-volatile memory space may also be enabled.

Advantageous effects

The conventional method for inputting an identification ID to a communication device is to use a DIP switch in which a plurality of single switches are combined, or a plurality of change-over switches, a rotary switch or a dedicated ID, an input device, a 7-segment display device for increasing or decreasing the number of bits of Up and Down, or various input devices such as a PC, a smart phone, a tablet, a smart board, a touch panel type input device, etc. which are connected for inputting an ID by communication.

The DIP switches are arranged in accordance with the individual settings of the individual switches, and when the ID of the binary number is input, the individual switches of each bit need to be provided all at once, and therefore, the DIP switches occupy a small space, but consume a large amount of power depending on the number of switches.

The present invention is one or two push switches, preferably, a tactile switch (tact switch) or a touch sensing input ID value in which a push condition is easily recognized by a tactile sense (click), and has advantages of low cost, small occupied space, freer product design, low power consumption, and ID input on a small-sized communication device.

The ID can be displayed by blinking by the LED in the device having no input ID display device, and therefore, the same advantages and effects can be obtained in the input ID display.

Best mode for carrying out the invention

The present invention is preferably applicable to a control unit that performs various remote controls for motor driving, an air conditioner, and the like, or a communication module that acquires various information and uses a sensor unit that remotely notifies information by communication.

Most preferably, it would be simply beneficial to apply a built-in timer of the microcontroller after the input of the microcontroller performing the communication function is connected to the LED flashing function and pressed by hand.

The number of digits of the ID specific bit value is calculated by the number of times of pressing a switch and is input, if no switch is input for a certain time, the number of digits is displayed by an LED, the number of digits is understood as the time for inputting the next digit, an LED, a switch and a timer of a microcontroller for receiving the input are applied in a mode of repeating the number of digits of the next bit value, the input ID is grasped by calculating the digit value of each digit by using an operation and storage device of the microcontroller, and then the input ID is stored in the storage device.

The function of displaying the currently input ID value is also responsive to a brief press of the switch, the change in the number of digits is to turn off the LED for a certain time, and the digit value is to display a multi-digit ID with the number of times of repeated blinking. This is a method and action suitable for confirming the input ID.

When the ID is updated and input, the switch is pressed for a certain time or more, and the microcontroller grasps the result and starts inputting the ID.

Detailed Description

Assuming that the ID uses a decimal number system which is a bit value notation (position indication), each digit number such as one, ten, one hundred, one thousand, ten thousand, etc. is recognized, and divided into a "digit change input" for inputting a meaning indicating a next digit coefficient and a "coefficient input process" for inputting coefficients 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 on each digit number, and IDs of other digit numbers such as two, three, four, etc. can be input by repeating the "digit change input" and the "coefficient input process" several times. If a hexadecimal system is used, the coefficients are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, such as a square of 16, a cube of 16, and have the power of each digit.

In normal operation, the input step is entered when identified by the microcontroller timer being entered by pressing the switch above "ID input Start input time (T1)".

Repeating the 'coefficient input process' and the 'digit change input' according to the decimal method or the hexadecimal method of the ID, and inputting the coefficients in the digits of each decimal method or the hexadecimal method. The "coefficient input" means uses the "digit input means" and the "digit change input" is executed after a certain time has elapsed from the "OFF" state of the "digit input means".

Since the electronic device cannot recognize the ID with several digits when the input is started, the length of the ID to be input is determined several times based on the "digit change input", and the ID input is terminated only after the "step termination input" indicating that the input is terminated by the final input is input, and the ID length and the ID value are determined. The "step termination input" means is similar to the "digit change input" and adopts a method of changing the "ON" or "OFF" time of the "digit input means".

When the 1-bit coefficient is input, the "digit number change input" is not performed, but the "step end input" notifying the microcontroller that the ID input process is completed is performed, and the timer determines that the ID input is ended after confirming that "step end input time (T3)" is maintained by "OFF" or "ON" of the "digit number input means for a time longer than or equal to" digit number input time (T2) ".

The input may be continued from the side with the higher number of bits to the bit side of 1, or the coefficient may be input in the reverse direction from the bit side of 1. Finally, when the microcontroller or the like calculates the ID, the respective coefficients may be multiplied in reverse order in consideration of the predetermined direction in order of magnitude of the power of 10 or the power of 16.

An example of inputting the ID decimal "375" on an electronic device using a microcontroller when the "digit input means" is a switch and an LED is as follows.

The process proceeds in the order of "ID input start input" - > "coefficient input process (3)" - > "digit number change input" - > "coefficient input process (7)" - > "digit number change input" - > "coefficient input process (5)" - > "step end input". In the input of ID375, the coefficients may be input in reverse order, i.e., 5, 7, and 3 from 1 bit.

Each coefficient input is a degree of repeating the operation of pressing and releasing the switch ("ON" and then "OFF"). The operation of pushing and releasing is repeated three times with a coefficient of 3. The time of "OFF" at this time should be shorter than the "digit input time (T2)" to have the "ON" of the subsequent switching turned ON. Otherwise it is judged as "bit number change input" instead of the switching required for coefficient increase.

When the coefficient is 0, the timer of the microcontroller recognizes that the switch is not pressed or is continuously pressed within the "digit input time (T2)" and the next digit of the coefficient is input.

Since the coefficient of the next digit is pressed to indicate that the "digit input time (T2)" has elapsed, that is, the digit has changed, and the input of the coefficient of the next digit is started based ON the change of the digit, when the blinking or "ON" status is displayed ON the LED.

Then, in order to input the next digit coefficient 7, the switch is pressed and released, and the "ON/OFF" switching is repeated 7 times, and then the "OFF state" of the "digit number input time (T2)" is waited again, and then the "digit number change input" is executed.

When the LED displays "digit input time (T2)" as having passed by On or blinking, the On/OFF switching input is repeated five times corresponding to the coefficient 5. When the 3-bit coefficient input, the digit number change input, the 7-bit coefficient input, the digit number change input, and the 5-bit coefficient input are completed, the 1-bit is determined by the timer as an input in which the input is completed, that the switch is not pressed for the "step end input time (T3)" but is turned "OFF" or the switch is continuously pressed "ON" for this time, and the ID input process is completed.

The "arithmetic device" takes the inputted 3, 7, 5 as the coefficients of each digit, multiplies the value formed between the digit change inputs of several digits by a power value of 10 according to each "coefficient input process", multiplies the coefficient of the first input by the product of the number of digit change inputs of 10, multiplies the coefficient of the second input by the product of the number of digit change inputs of 10, multiplies the coefficient of the third input by the product of the number of digit change inputs of 10, and adds the multiplied coefficients. That is, 3, 7, and 5 of 375 are multiplied by 100, 10, and 1, respectively, and added to each other to obtain 3 × 100+7 × 10+5 × 1, which is 375, thereby calculating an ID, which is stored in a nonvolatile storage device and then used as the ID. The arithmetic device can also be built in a microcontroller "

When the coefficient is 0, the method is selected from methods of repeatedly switching 10 times or not inputting for a certain time (inputting 0 times). If the ID is used in hexadecimal, the coefficient 0 is a method of switching 16 times or not inputting for a certain time (inputting 0 times).

The in-process time interval is a confirmation of whether or not the "digit number input time (T2)" or the "step end input time (T3)" has elapsed, and is set to T2< T3. The coefficient input process is that the 'digit input means' needs to be switched OFF at the same time within the time T of T < T2, and the 'digit change input' is that the 'digit input means' is continuously switched OFF or ON within the time T of T2< T < T3. If the input is terminated for a time T3< T, that is, T time, the timer judges this and knows that the input is terminated.

The input person cannot accurately grasp whether the "digit input time (T2)" or the "step end input time (T3)" has elapsed, and therefore, it can be grasped by "ON" or blinking of the LED light. In an electronic apparatus including a touch panel or other screen display devices, a number can be directly notified through the screen display devices. If the system is equipped with a buzzer or speaker, a short beep can be used. As described above, the LED, the screen display device, or the sound generation device is referred to as an "information display device".

The 'information display device' is linked with the operation of a connected circuit or a timer of the microcontroller, and is used for displaying the 'digit input time (T2)' that the next digit coefficient is input in the input process. It can also be used to inform the step termination input time (T3) that the input step has ended.

The "information display device" may be configured to display the number of input and stored IDs, and to display the coefficient of each digit of the input and stored IDs by LED blinking or by another "information display device" (when the coefficient of the LED or audio display means is 0, no operation is performed for a certain time, or ten operations are performed, and the hexadecimal number system does not perform any operation or sixteen operations), and the display of the next coefficient after the display of the coefficient is completed means that no operation is performed by the LED or audio display device for the "display digit change time (T4)". When an "information display device" capable of displaying information on a screen is used, a method of displaying a coefficient value by a special display or a shift in numerical display on a screen may be used.

Since the display of the ID is completed, that is, the display is displayed without any content to be displayed again when the ID is displayed, the display of the "information display device" is not operated or the LED is turned on or the display of the "information display device" is maintained during the "display ID output termination time (T4)" as the display for calculating the ID, thereby notifying the user that the ID display is completed. When the screen is used as an "information display device", it is more convenient to directly display the decimal ID on the screen in a number.

For the input by the doctor who requests the display of the ID or the input by the doctor who wants to re-input the ID, the "digit number input means" for coefficient input may be used directly, and the "second digit number input means" may be used for coefficient input and action, respectively. The distinction is made between the ID input process and the request for display of an ID or the meaning of the start of ID input, depending on whether the operation of the "digit number input means" is performed after or before the start of input.

However, since the input for requesting display of the ID and the input for re-inputting the ID need to be distinguished from each other, if the input of the "digit input means" or the "second digit input means" is "ON" and is held for a shorter time than the "ID input start input time (T1)" during normal operation of the electronic device, that is, before the input is not started, it is regarded that the ID is requested to be displayed, and if the holding is longer (the switch is pressed and held), it is regarded that the step of inputting a new ID value is currently performed, and the input step is performed.

The ID display also requires a process of distinguishing the number of coefficient digits, which is "display digit change time (T4)", and the distinguishable time when the ID display is completed is "display ID input completion time (T5)".

Since it is difficult for the input person to know whether or not the respective times of "ID input start input time (T1)", "digit input time (T2)", "step end input time (T3)", "display digit change time (T4)", and "display ID output end time (T5)" have elapsed, the timer determines this, and the "information display device" notifies the input person of the arrival of the time (LED) by "ON" or blinking for each cycle, and the input person performs the ID input process based ON the display. And if the screen of the LCD, OLED or other visual display devices such as a touch screen or a panel is used instead of the LED, the coefficient values can be directly displayed on the screen by decimal numbers or sixteen-numbered numbers.

It may be convenient to make a special display on the "information display apparatus" when the ID is not initially input and an input requesting display of the ID is received. If an LED is used, the extremely short period of flashing may be continued for more than a certain time. A very short period of flashing may also be used to notify that the ID entry process is on. If the ID is not initially input, if an input requesting display of the ID is received, the display is automatically switched to ID input on, and for the display, the display is displayed such that the LED blinks for a short period and the display requests the start of ID input.

As described above, when the decimal system is used, if the coefficient input of 0 to 9 in each bit or the coefficient of 0x0 to 0xF in each bit in the hexadecimal system and the "digit change input" before and after the coefficient input are used, the arithmetic device of the connected line or microcontroller can calculate the decimal or hexadecimal ID value. The calculated ID value is stored in a nonvolatile memory space, and may be stored in a built-in nonvolatile memory space of the microcontroller or an external storage device, and the value is read for use as an ID at the time of reinitialization.

Industrial applications

In various places such as homes, public buildings, public facilities and the like, control requirements for various purposes such as illumination, motors, air conditioners, humidity, temperature, safety and the like, and sensor network requirements are required, and a central management station or an administrator needs to remotely control various distributed control terminals and perform a function of collecting various required sensing information from various sensors.

The distributed plurality of control objects and sensors have a communication function unit for collecting sensor information by communication, and control is performed by selecting an object from the plurality of control objects, or by providing an inherent ID for identifying each control object or sensor in order to acquire sensor information, and including the ID in a communication packet, and only the packet information or control value corresponding to the own ID is reacted, or position information detected as a sensor value may be additionally used. Since the sensors to be controlled each have a communication function section so as to be remotely connectable, it is understood that the actual sensor or the ID to be controlled is the same as the communication ID. The same applies to various wireless communications such as ZigBee and ZWave, and various wired control communications such as RS-485, DALI, and DMX.

The present invention is industrially applicable because it improves the disadvantages of the conventional ID input method according to the need of inputting an actual identification ID to a control terminal or a sensor installed in each business of industry for remote control or sensing as described above.
