In this case, since the current device has a waterproof property of about IP 6 or IP 7 (waterproof reference unit), there is a problem that the safety of the device can not be guaranteed when submerged in water for a long time.

In addition, various methods have been studied for transmitting and receiving to AMR terminals and metering centers, and RF methods have been developed to solve the problems of construction costs and management costs of wired lines, which are major disadvantages of wired lines. Since the instrument that needs to be updated continuously consumes power, a separate power source is required for power supply.However, a meter-based instrument, such as gas or water, needs to be visited by a meter reader to replace the battery due to continuous power consumption. there was.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

First, referring to FIG. 1, the wireless meter reading terminal according to the present invention is connected to a meter such as electricity, water, and gas, and has a case shape having a cover and an antenna.

The inventors of the present invention wireless metering terminal 150 is provided with a wireless meter reading unit 160 and a wake-up synchronization circuit for reading the amount of use of the meter, a specific low-power wireless transceiver module (RF) for transmitting the meter data to the repeater / hand terminal 15, an immersion detector 18 capable of detecting an inundation state of the wireless meter reader terminal, an operation detector 17 for monitoring an artificial operation of the wireless meter reader terminal, and a power supply unit for supplying power to each component ( 20).

The manipulation detecting unit 17 includes a cover opening detecting unit capable of detecting artificial manipulation due to opening and closing of the cover, and an antenna manipulation detecting unit detecting artificial manipulation such as antenna removal.

The wireless meter reading unit 160 accurately reads the normal pulse signal and the distorted pulse signal of the output pulse of the meter introduced through the meter meter pulse interface unit 19, and the count of the detected meter pulse signal is made accurate. Through the sensor module array block 13 composed of a microcontroller (MCU) (10) and a detection sensor module (11) equipped with a program for operating a signal interface, the meter pulse signal such as electricity, gas, water, etc. Detect.

And a download block 12 for downloading operation software for operating the meter pulse interface 19.

The microcontroller 10 serves as a main for performing control of each component, and the wireless meter reader terminal 9 generates a wake-up event to operate to switch to a power saving mode to minimize current consumption. ) Is further included.

When described in detail the operation and effect of the wireless meter reading terminal of the present invention configured as described above.

Referring to FIG. 1 showing the wireless meter reading terminal of the present invention and FIG. 2 showing a circuit diagram of the detection sensor module and FIG. 3 showing a flowchart of a program for the normal reading of the meter pulse signal, the reading process of the wireless meter reading terminal 150 is The pulse signal of the magnetic contact switch 36 outputted from the pulse type meter side 35 such as gas, electricity, and water may be transferred to the sensor module 11 through the meter pulse interface unit 19 separately configured in the wireless meter terminal. It is transmitted to the input signal line 30. The signal from which the high frequency component has been removed through the capacitor 25 is transferred to the input signal line of the detection-only processor 21 via the surge noise inflow preventing diode 23 introduced from the meter side.

The transmitted signal is analyzed by the program used for the normal reading of the meter pulse.

Looking at the process of analyzing the meter pulse signal as a normal signal,

When the pulse signal of the meter is input, the program of the detection sensor module starts monitoring of the input pulse signal based on meta pulse monitoring and the set initial parameter S300 (S310), and checks the period of the input pulse. (S320), if the high pulse period is checked (S330), it is determined whether the high pulse signal is a normal signal (S340), if the high pulse signal is normal, and check setting the low pulse period (S350), the set Monitor the low pulse period.

If the high pulse signal is not read as a normal signal (S340), the signal is configured to be monitored again.

As described above, when the pulse signal period is checked while the pulse signal is checked while the low pulse period is checked (S360), it is read whether the low pulse is a normal signal (S370), and when the read signal is the normal signal, The high pulse period is checked and set (S380), and a wakeup signal and a pulse latch signal are generated (S390).

The check setting of the high pulse period (S380) is to allow the monitoring control to be circulated.

If the low pulse is not read as a normal signal, the low pulse is configured to allow monitoring control.

After the low pulse is read as a normal signal, the generated wake-up and pulse latch signals are read from the microcontroller 10 by completing the processing of the signal and reading the latch release signal generated by the sensor module (S400). When the generated signal is read as the latch release signal, the pulse event is terminated (S410).

If it is not read as the latch release signal, the wakeup signal and the latch signal generated return to the initial stage and are monitored again for the signal pulse.

The program driven as described above is always circulated to monitor and control the signal of the pulse, and reads the normal signal.

When the program analyzes the signal as a normal signal, the microcontroller 10 generates a one-shot low clock at the wake-up signal 33 line for starting the microcontroller 10 in the power saving mode. ) Generates a low output to the line of sensor input detection signal 31 that allows the meter pulse to be detected once.

The signal for wake-up of the microcontroller 10 is kept low for 0.03 seconds and then immediately reduced to a high state, thereby preparing to respond to a pulse signal of a meter that is generated later.

In addition, the microcontroller 10 stops the power saving mode by the wake-up signal and returns to the normal operation mode to output the sensor input detection signal 31 output latch output from the dedicated processor 21 in the sensor module 11. (Latch) state is checked, the counting operation is performed, and the counted data is stored in the nonvolatile memory 14, and at the same time, the low signal is released to the unlatch signal 34 line by the dedicated processor 21 of the sensor module 11. Signal and outputs the latch release signal 34 to the high level when the sensor input detection signal 31 level is changed to the high state, and the dedicated processor 21 of the detection sensor module 11 is outputted. When the one-shot low signal of the latch release signal 34 transmitted from the microcontroller 10 is input, the microcontroller 10 determines that the counting operation for the input pulse is completed, and the sensor input detection signal ( 31) to High The. The counting process is completed as the counting process for the input signal is completed as described above.

 The microcontroller 10 is switched to the power saving mode when the time to send data to the repeater has not elapsed.

The resistors 28, 27, 26 are used to maintain the base level values of the signals for interfacing with the microcontroller 10, the resistors 29 being protective elements.

The wireless transmission / reception module will be described in detail with reference to FIG. 4. When the specific low-power wireless transmission / reception module 15 including the wake-up circuits 132, 133, and 134 is transmitted from the transmitter, a transmission output data signal waveform 137 for wakeup is transmitted. A signal flows through the antenna 120, and a signal passing through the band pass filter 121 flows into the chopper circuit 132. The chopper circuit 132 converts the transmission output data signal waveform 137 for wake-up of the FM modulation output from the transmitter into an AM signal similar to the amplitude modulation waveform by using a chopper, and then transfers it to the detector 133. After analyzing whether the signal has a signal and a frequency above a certain level, the signal is transmitted to the wake-up circuit 134 to generate a wake-up signal 135 and transmitted to the microcontroller 10.

The wakeup signal applies power only to the wakeup circuits 132, 133, and 134 so that power is not applied to the main receiver circuits 120 to 131, thereby reducing current consumption. In order to reduce the current consumption for the power supply used internally, the wake-up circuit 132 ~ 134 is activated at regular time intervals using the intermittent operation method, and the operation is prohibited for other times to minimize the current consumption.

In addition, the intermittent operation to reduce the current consumption of the wake-up circuit (132 ~ 134) is linked to the meter reading period by using the timer (9) attached to the wireless meter terminal so that the wake-up circuit is not driven during the period except for the meter reading date. do.

The microcontroller 10 that has been woken up by the wakeup signal 135 generated from the wakeup circuits 132 ˜ 134 wakes up the circuit 132 in order to receive the normal transmission data signal waveform 138 transmitted from the transmitter. The power of the main receiver circuits 120 to 131 is applied and the reception operation is performed. The FM modulated signal received through the antenna 120 is passed to the local mixer 123 via the bandpass filter 121 and the primary amplifier 122, which in turn is the secondary amplifier 125 and the lowpass filter 126. And then it is transmitted to the demodulator 130 through the IF mixer 127 and 455KHz IF (129), and the demodulated transmit data output 131 is transmitted to the microcontroller 10.

The main receiving circuit operation is a super heterodyne type receiving circuit, and a description of the circuit operation will be omitted.

The operation detection unit 17 and the submersion detection unit 18 of the present invention wireless metering terminal 150 will be described in more detail with reference to FIGS. 5, 6, and 7.

First, referring to FIG. 5, the circuit operation of the operation detection unit and the submersion detection unit will be described. Due to the wake-up signal generated by the timer 9 after a predetermined time has passed through the microcontroller 10, the power saving mode is switched to the start mode. Then, the immersion / manipulation enable enable signal 66 is output low. The transistor 50 is turned on due to the output immersion / operation detection enable signal 66 and power is supplied to the immersion detection rods 63 and 64 of the manipulation detection unit 17 and the immersion detection unit 18. Is applied.

When power is applied to the manipulation detection unit 17, if the case cover 70 or the antenna 62 is attached to the circuit operation of the manipulation detection unit 17 (see FIGS. 7 and 8), the magnetic ( Since the contacts by the magnetic force of the 71 and 74 and the reed switch 72 are always closed, both ends of the case cover opening and closing detection signal 170 and antenna operation detection signal 162 connected to the resistors 52 and 53 are closed. Maintains the low level. If one of the magnetic 71 and 74 and reed switch 72 structures is changed in the magnetic 71 and 74 and reed switch 72 structures, the case cover opening / closing detection signal connected to the resistors 52 and 53 ( 170 and the signal level attached to the portion of the antenna operation detection signal 162 is changed to a high state, the microcontroller 10 is the cover opening and closing detection signal 170 and the antenna operation detection signal of the case By reading 162, the presence / absence of operation can be detected.

On the other hand, when the power is applied to the immersion detection unit 18, the power supply is supplied to the (+) side 64 of the immersion detection rod, when the immersion state 65 is an electrical conduction state between the two poles of the immersion detection rod (- The current flows to the side 63 so that the current and the voltage drive the transistor 51 so that the immersion detection signal 67 is connected to a resistor (not shown) connected to the emitter terminal of the transistor 51. The level is kept high. Under the condition that the immersion state 65 is not achieved, the immersion detection signal 67 level connected to the resistor connected to the emitter terminal of the transistor 51 has the power applied due to the turn off state of the transistor 51. This keeps the low level due to the connection to the ground opposite the resistor.

Accordingly, when the microcontroller 10 detects a case cover open / close detection signal 170, an antenna operation detection signal 162, and a submersion detection signal 67 with a low level, the microcontroller 10 subsequently submerges / operation detection enable signal 66. After suppressing current consumption by outputting the level high, if there is an abnormality in the detection result, a status information code is generated, and the status information is transmitted to the repeater or the hand terminal through the wireless transmission / reception module 15.

The operation detecting unit 17 attaches the magnetic 71 and 74 to the positions 58 and 59 displayed on the outer side of the wireless meter reading terminal case of the present invention (see FIGS. 7 and 8), and the reed switch on the circuit board 73. The 72 is attached and fixed, but the reed switch 72 is installed in close proximity so that the driving of the reed switch 72 may be performed.

7 and 8 illustrate different forms of the operation sensing unit, and FIG. 7 illustrates the use of a rectangular magnetic 71 attached to the inside of the cover case 70, and FIG. 8 illustrates a magnetic having a circular shape. It is attached around the antenna.

The immersion detection unit 18 is necessary for a water meter embedded in the basement, and the immersion detection unit 18 inserts a circular insert 65 into the case body as shown in FIG. (64), the immersion detection rod (-) (63) is inserted through the insert and connected to the signal line at the end of the detection rod introduced into the wireless meter terminal, and installed in the lower end of the outer case.

Since the water immersion rods 63 and 64 are injected with air into the insert internal space 68, water is not filled, so that the end of the immersion rods extends to the portion 69 drawn by the surface tension of water. The contact is smooth, and the insert is installed inside the case lower part so as not to malfunction with respect to the water flowing through the case 70 outer surface.

The meter reading data transmitted from the wireless meter reading terminal configured as described above is transmitted to the management server of the central computer via the wireless communication network without going to the meter reading center far away from the meter / hand terminal.
