The blinking start of the LED 12 is normally performed at 3.3125 seconds from the start of transmission. This time can be shortened without considering the extension of the battery life. While the LED 12 is blinking, no other transmission input is accepted. It is also possible to receive using the memory.

The transmitter 1 has a line frequency of 426.0250 MHz to 416.1375 MHz (12.5 KHz interval), and is 426.050 MHz unless otherwise specified, with a deviation of ± 4 × 10 ^{− The} occupied frequency bandwidth within ⁶ kHz is within 8.5 KHz, the transmission time is 40 seconds at the maximum, and the detection time is 1 second or more with the dial 11 as the maximum.

  As for the data format, the preamble repeats 1 and 0 alternately, and 1600 bits are transmitted as a standard, but this length can be changed by the setting of the built-in EEPROM. The frame period signal is 32 bits in total, the identification code is 1 bit in the ID / message identification flag (0 = ID), the vibration pattern is 3 bits, the group ID is 9 bits, the individual ID is 8 bits, and the BCH code is 10 The bit and the parity check bit are 1 bit (even number parity), and a total of 32 bits are set as one batch, which is Manchester encoded and transmitted. For character data, ID / message identification flag is 1 bit (1 = indicates character data), character data is 20 bits (2.5 characters to represent 1 character in 8 bits), BCH code is 10 bits, The check bit is 1 bit (even number parity). This 32 bits in total is Manchester encoded as a batch and sent following the identification code. In this embodiment, it is assumed that the length of the preamble can be shortened and the number of transmissions can be set to a plurality of times. When transmitting 10-character data, 4 batches of data are required following the identification code.

  The transmitter 1 is supplied with power by turning on the power switch 9, and the detection circuit starts operating. If automatic transmission at power-on is enabled in the EEPROM settings, the sensor ID is forcibly transmitted when the AC adapter is used.

  The transmission operation is performed by detection by various sensors or input from the transmission switch 13. This one-time transmission time is 3.125 seconds as a standard, and at this time, the LED 12 blinks as described above. When this transmission is performed, a pause time is required for a minimum of 2 seconds. Seconds.

  Further, when the detection operation of the transmitter 1 is voice detection, the sensitivity of the signal from the microphone connected to the microphone jack 14 is adjusted by the input volume 10, amplified and detected, and then for the time set by the detection volume 11. Transmission starts after the elapse. A radio wave detection circuit for mobile phones is built in to support mobile phones, and a dedicated modular cable is connected to the microphone jack 14 to support phone line connection type facsimiles to detect call signals on the phone line. Then transmission starts. Also, if characters are input from the personal computer to the microphone jack 14 through the interface, 10 characters can be transmitted. Of course, the microphone jack 14 cannot be used simultaneously with the voice detection.

  With regard to the ID setting, 512 group IDs and 256 individual IDs can be set, and there are three types that can be set for 10 character transmission with this individual ID, and other IDs are fixed 5 characters or arbitrary 10 Can be set for character transmission.

  Next, the receiver will be described with reference to FIGS. FIG. 2 shows a wristwatch type, A is a front view, B is a rear view, C is a side view, and D is a bottom view. The wristwatch-type receiver 15 can be attached to and detached from the wrist by connecting a belt to the connecting portions 16 and 16. 3 shows a portable box type, A is a front view, B is a rear view, C is a plan view, D is a right side view, and E is a left side view. This portable box-type receiver 17 has a through hole 18 in which a strap can be attached. The reception method is a single superheterodyne method.

  The power supply of these receivers 15 and 17 is such that when the wristwatch-type receiver 15 completely closes the battery cover 19, or in the case of the portable box-type receiver 17, the mode selection switch 20 is slid. This is done when the vibration or sound is set, and the LCDs (display units) 21 and 22 on the front surface are all turned on, and then the management number is displayed for a certain time to display the time. If left as it is, the LCDs 21 and 22 disappear in 10 seconds, and the normal standby mode is set.

  This reception operation is repeated intermittently at a rate of once every 3 seconds (depending on the EEPROM setting). The reception time of one time is about 30 ms when not sent, and if a preamble signal is detected at the time of reception, the reception operation is continued, and for a maximum of 3.3125 seconds (due to intermittent setting), sync code detection, ID Perform detection.

The line frequency of each of the receivers 15 and 17 corresponds to the transmitter, the reception sensitivity is 0 dBuVemf or less (chassis sensitivity), the spurious response is 40 dB or more (excluding images), the adjacent channel selectivity is 30 dB or more (reference sensitivity ratio), Local oscillator frequency fluctuation is within ± 4 × 10 ⁻⁶ , unnecessary radiation is 4nW or less, operating temperature and humidity are minus 10 degrees Celsius to 50 degrees Celsius and plus 35 degrees Celsius, 95%, no abnormalities, built-in antenna The loop antenna and battery saving are received once every 3 seconds for about 30 ms (when there is no signal in the standard area).

  The receivers 15 and 17 receive the sync code during the reception period. If the subsequent ID can be received without error, the receivers 15 and 17 compare with the set ID, display a message corresponding to the matching ID on the LCDs 21 and 22, and the vibrator. Vibrate to alert you of this incoming call. In the case of the optical flash, the LED built in the flash unit 23 is flashed. Switching between vibration and buzzer in the receiver 17 is performed by a switch 20. These operations are for IDs 1-8. If the ID is 9 or more and the subsequent data is character data, the data is continuously received and stored. The display is switched and displayed in units of 5 characters, and the vibration of the vibrator responds with the pattern set in the EEPROM by the vibration number transmitted together with the ID. If the time switch 24 or the alarm switch 25 is pressed during the response operation, the incoming call notification operation is stopped.

  The time setting in the receivers 15 and 17 is set to the time setting mode when the time switch 24 is kept pressed for 2 seconds or more in the normal standby state. 12a00 is displayed. When the time switch 24 is pressed, the time increases in increments of 1 hour, and when the time switch 24 is pressed for 1 second or longer, it increases continuously. After 11 o'clock, 12p00 is displayed. When the alarm switch 25 is pressed, it increases in increments of 1 minute, and continuously increases when pressed for 1 second or longer. If left unattended for 10 seconds, the time is set.

  In the normal standby state, after the alarm switch 25 is pressed to display the time, when the alarm switch 25 is continuously pressed again for 2 seconds or more, the alarm setting mode is set. If no alarm is set when entering this mode, 12A00 is displayed, the time unit can be increased by the same operation as above, and if it is left for 10 seconds, onOFF is displayed, and when the time switch 24 is pressed, the letters ONoff are displayed, When the alarm switch 25 is pressed, onOFF is displayed and the one displayed in capital letters is effective. If left unattended for 10 seconds, it exits the setting mode and returns to the normal state.

  In addition, when the time is displayed for 10 seconds or more in the normal standby state, the time is not displayed. However, when the time switch 24 is pressed, the time is displayed, and when the continuous display mode is desired, the time switch 24 and the alarm switch 25 are simultaneously set. Press and hold for more than 2 seconds. When the button is pressed, the display appears once, and after 2 seconds or more, the display disappears, so it can be confirmed that the mode has been switched. When the switch is released, the display mode is always displayed. In order to return this, similarly, by pressing both switches 24 and 25 simultaneously for 2 seconds or more, the display disappears and the normal standby state is entered.

  When an alarm is set and the current time reaches the set time, “mesh” is displayed and the same operation as when receiving a response is repeated. If the time switch 24 is pressed during this operation, the alarm operation is stopped.

  Further, when the battery switch 26 is pressed, the backlights on both sides of the LCDs 21 and 22 are turned on only while the battery voltage is being pressed, and the vibrator vibrates. In the case of the receiver 17, a vibration or buzzer sounds depending on the position of the switch 20, and at the same time, the LED flash unit 23 is also lit. When the voltage is the receiver 15, the vibrator does not operate at 2.5 V or less, and when the voltage is 17, it is 1.0 V or less. When the voltage drops in the normal standby state, “DENCH ×” is displayed at the timing when the display disappears from the LCDs 21 and 22 at the time of reception response or time confirmation. When the time switch 24 or the alarm switch 25 is pressed in a state where the time is always displayed, the display “DENCH ×” is displayed.

  When the alarm switch 25 is pressed, the memory call displays the last received message and time in order.

  The ID can be set to 4 group IDs and 8 individual IDs. Individual ID1 and ID5 are for endless mode, and up to three individual IDs can be set for fixed 10 characters and one for arbitrary 10 characters. Others are for fixed 5 character setting.
