Description of Invention (1) (Background of Invention) (Scope of Invention) In the report device, especially related to energy devices. (Description of the previous technology) The actual application of the alarm system in the installation of police devices in remote buildings to remote monitoring centers, disaster detectors, etc., are pseudo-connected to these devices, and are detected by these detectors Report to the monitoring center. When the telephone line is disconnected due to other reasons, the alarm reports that the detector has detected an abnormality. As a result, the signal is sent to the monitoring center for example. If this signal is not disconnected from the weekly telephone line, send a guard to take the necessary measures as appropriate. Conversely, monitor the alarm reporting device flowing through the telephone line during the alarm report shipment to determine that the telephone line of the telephone staff has been disconnected . When the telephone line is open, it is not possible to borrow electricity. The alarm on the alarm line of the telephone line is used to monitor the alarm report of the disconnection of the telephone line. The alarm report device is connected to this alarm report. Various sets of monitoring buildings are used for monitoring. Various detectors, such as night burglar detectors, alarm reports in the alarm system are sent out through the telephone line when an abnormality is installed. For some reason in this alarm system or they cannot go to the surveillance center, even if the alarm is detected The system is useless. From the alarm report every 1 to 2 hours, when the monitoring center receives this signal periodically, the monitoring center will determine the corresponding building to confirm whether it is safe. Set the side, and transmit current on the above-mentioned periodic signal. If the current is not detected at this time, the line is disconnected, and the buzzer is used to warn if the current is detected during the interval of periodic signal transmission. Therefore, when opening the road, each paper scale applies the Chinese National Standard (CNS) A4 * see grid (21〇X29 " 7mm) V. Description of the invention (2) A7 B7 Printed dialects of Beigong Consumer Cooperatives, Central Bureau of Standards, Ministry of Economic Affairs Therefore, it is different from the production test plus | Line judgment, slang flow, resistance flow, Yi Yi detection increase, external warning, no warning, immediate power supply, fixed power, capacitance, line ground, and S. Measurement and monitoring of electric power. The line judgment is high, small, and isolated. Station Jing The pretense of investigative newspaper can be one as usual. Compared to seeing the interfering capital and monitoring the difference between the police when the police is on the line, the supervisor will send it to the eye, and the line will be taken out at the same time under normal pressure _ to be able to pass, transfer to the local Station calls vary. The voltage is measured between the voltage and the voltage is measured, and the shadow is formed. The electric wire on the electric wire is detected by the lotus, and the signal is sent to the low. Reported by the supervisor of Chengchuang, including visual and electrical measurement, small profit, and good visibility. This line can be used at regular times to set the reconnaissance and reconnaissance during the period of extremely vulgar benefits. This line is easy to be closed due to the increase in the sound cycle. If the system is to measure the volume, it will be short, but the purpose of the line is to report the electric closure of the time table 4, and the measurement and detection will be constricted. Plus. Born. When reporting the report, let it flow out of the report line, suppress the detection and detect it, and pay attention to the number of production lines. Pressure, flow pressure. And can the second #) the time of the line of the false detection line current and electricity is cut off. If the KSL is sent, the line is the normal pressure monitoring line. The current of the wire is relatively judged by the supervision, and the pseudo-disguised electricity on the W power is already on the wire, and the power of the fch is considered. Flow 卽 U It is clear that this line should be treated as a line by the power supply. The power failure is the line error of the small supervisor: 10 is installed and tested and used. It ’s a matter of sight and sight, but it ’s very wrong to use it. * # At the time of the report, Shangli Liudian is the electric supervision line, so the line is more borrowed.

When the line voltage monitoring measures detect an abnormality, the disconnection determination measures enable the electricity to be read first ik 1 1 The line closure measures close the DC of the telephone line Loop 9 and current-on-line current monitoring measures ^ 3 II 1 then detects the phone Distinguishment measures when the circuit is closed are abnormal. 1 I The telephone line is disconnected and a disconnection signal is output. 0 If the telephone line is closed, the line item 1 -J recurrent monitoring measures. No abnormal signal is output to the discrimination measures. The latter is Judgment of writing 1 There is no disconnection on the telephone line. Page 1 — 1 I According to this configuration, when the telephone line is opened, the line voltage iSy drops 1 1 when the line is disconnected. The line voltage monitoring measures detect an abnormality. Secondly, when the phone is 9 When line 1 1 is closed and Jhrr's current is flowing, line current monitoring m detects an abnormality. The result is unordered. T Disconnection detection measures output a disconnection signal. Conversely * When 1 disconnection occurs but due to noise Make the line voltage monitoring measures detect abnormal voltage 1 I. When the telephone line is closed, the wired current flows. Once this line is detected • The disconnection determination measure after 1 1 current is that the farm disconnection is determined. Therefore, there is no disconnection signal No. 1 output. Then, the malfunction due to noise can also be avoided. Only the online voltage monitoring measure determines that there is a disconnection. The monitoring of 1 1 line current may only be performed. Therefore, 9 can reduce the number of times the telephone line is closed * and 1 1 can avoid the alarm.% The increase in the system's operating cost. 1 1 The invention can also store a small voltage in the capacitor »and monitor the capacitor The discharge current of 1 1 monitors the line voltage 9 instead of detecting the minimum current of 1 I caused by the m-line voltage. In this case t the effect of noise on the discharge current becomes smaller • 1 | The line voltage is monitored under conditions. Therefore, 9 can be used. 1 1 1 1 1 This paper scale is applicable to the country's "Household Standard (CNS > Α4ί 见 格 (210X297mm) ^^ 2565 ΑΊ Β7 V.

Description of the invention u) Central monitor 2. To detect the disconnection alarm monitoring circuit 12 of the telephone line 5 The telephone line must be shut off periodically and a predetermined signal is sent to the central monitor 2. Since the structure and operation of the alarm monitoring circuit 12 are well known to me, detailed description is omitted. Disconnection circuit 2 pseudo configuration It is used to detect the side of the reporting device; ^ The disconnection of the telephone line. The input terminals L1 and L2 of the disconnection detection circuit 21 are pseudo-connected to the telephone line 5, and the output terminals L1 'and L2' are connected to Report monitoring circuit 12. One of the input terminals L1 is commonly connected to one of the output terminals L1 through the line current monitoring circuit 24, and the other input terminal L2 is directly connected to another output terminal L2 '. The line voltage monitoring circuit 23 is provided between the input terminals L1 and L2. The output signal of the line current monitoring circuit 24 and the output signal of the line voltage monitoring @ 路 23 are input to the CPU (Central Processing Unit) 22. An alarm 25 containing a buzzer or flashing light is also connected to this PCU22. The CPU * is connected to the line closed circuit in the alarm monitoring circuit 12 • Outputs the instruction to close the telephone line, and detects the closed state of the telephone line. FIG. 3 shows the structure of the line voltage monitoring circuit 23. The voltage between the input terminals L1 and L2 is rectified by the full-wave rectifier D1 and then divided by the resistors R1 and R2. The power supply voltage VI is divided by resistors R3 and R4. The two divided voltages are pseudo-input to the comparator CP1, and the output of the comparator CP1 controls the OH / OFF of the transistor Tr. The photodiode PPD1 of the photocoupler PC1 is commonly connected between the transistor Tr and the power supply VI. The phototransistor P T 1 of the optical coupler PC1 is connected to C P U 2 2. Here, when the line voltage is assumed to be a stable value, the output of the comparator CP1 becomes L (low), and the transistor Tr is not turned on.

Description of the invention (7) Diode PD1, but the photoelectric crystal PT1 does not conduct. In contrast, when the line voltage decreases, the output of the comparator CP1 becomes H (high), and the call crystal Tr is turned on, and then the current flows through the photodiode PD1 to turn on the phototransistor PT1. FIG. 4 shows the configuration of the line current monitoring circuit 24. The optical diode of the optical duplexer PC2 is pseudo-connected between the input terminal L1 and the output terminal L1 '. The output of the photodiode PT2 is connected to the CPU22. Here, the phototransistor PT2 is turned on when current passes through the telephone line 5, and the phototransistor PT2 is not turned on when no current flows. Next, the operation of the CPU 22 of the disconnection determination circuit 21 will be described with reference to FIG. In addition, the discrimination circuit 21 is generally used to detect the disconnection of the telephone line 5 on the side of the alarm reporting device 4 as described above. As for the processing required to detect the disconnection of the telephone line 5 on the side of the monitoring center 1, the alarm monitoring circuit 12 is executed in the same manner as the system of the prior art. First, at step S1 in Fig. 5, it is determined whether the telephone line 5 is disconnected. This discriminating action checks the state of the closed circuit 13 of the telephone line inside the alarm monitoring circuit. When the result of the judgment is negative (closed circuit), the flow proceeds to step S4, and if positive (open circuit), step S2 is performed. Printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling in this page) Step S2 Ye performs voltage monitoring. That is, the state of the photoelectric crystal PT1 of the line voltage monitoring circuit 23 is checked. Since the telephone line 5 is open in the state of step S2, if the loop voltage exceeds a predetermined value, this state is judged as normal, otherwise, it is abnormal. In other words, if the photocell PT1 is not conducting, this state is determined to be normal, and the flow returns to step S1, otherwise, it is abnormal, and the flow proceeds to step S3. There are also cases where there is no disconnection due to noise interference, but it is misjudged as different. The paper size is applicable to the Chinese National Standard (CNS) Α4 present grid (mm) A7 B7 322565 V. Description of the invention (8) The normal state. Therefore, the flow proceeds to the subsequent steps such as S3 to perform the disconnection confirmation. --------- f I installed-- (Please read the precautions on the back before filling in this page) At step S3, the CPU 22 outputs a signal to the telephone line closed circuit 13 of the alarm monitoring circuit 12 to enable alarm monitoring The telephone line in loop 12 is closed. When the telephone line is closed, if necessary, a predetermined signal is transmitted from the alarm reporting device 3 to the monitoring center 1. In step S4, Wang performs monitoring of the telephone line. That is, the state of the photoelectric crystal PT2 of the telephone line monitoring circuit 24 is checked. Since the telephone line 5 is closed at step S4, if the line current exceeds a predetermined value, this state is determined to be normal, otherwise, it is abnormal. In other words, if this state is determined to be normal when the photoelectric crystal PT2 is turned on, the flow returns to step S1, otherwise, it is determined to be abnormal. The flow proceeds to step S5. Because the current larger than the line voltage is used to monitor the line current, there is no erroneous judgment due to the sound. At step S5, the report circuit 25 outputs an alarm, and the determination of disconnection has been completed. When the alarm is output, the buzzer and the blinking indicator will sound, so that the alarm reporting device 4 side can determine the disconnection of the telephone line 5. Printed by Beigong Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs As explained above, when it is judged that there may be a disconnection by monitoring the line voltage, the possibility of this disconnection is determined by subsequently monitoring the line current. Therefore, even if any misjudgment is caused by noise during the monitoring of the borrowed line voltage, the above method can always correctly determine the disconnection of the telephone line. Since the monitoring of the line current is performed only when the telephone line is open, the number of times the telephone line is closed can be reduced, thereby avoiding the increase in the transfer cost of the chub. In the above example, the disconnection discrimination circuit 21 false alarm monitoring circuit -1 0-This paper scale is applicable to the Chinese National Standard (CNS) (210 X 297mm) 3S2565 A7 B7 5. Description of the invention (9) 12 separate structure However, the disconnection determination circuit can also be assembled in the alarm monitoring circuit 12. Next, a modification example of the line voltage monitoring circuit 23 will be described with reference to FIG. 6 attached. In Fig. 6, the symbol C1 represents a capacitor, which is used to draw a very small current through the line voltage. Full-wave rectification D3 for rectifying line voltage, constant voltage circuit CC1, photoelectric crystal PT3 of optocoupler PC3 and diode D4 are connected into a charging circuit to charge this capacitor C1. In addition, the constant voltage circuit CC1 includes a transistor TR1, a diode ZD1, and resistors R5, R6, and R7. Furthermore, the discharge transistor R8 and the photodiode PD5 of the photocoupler PC5 are connected as a discharge circuit to supply the discharge of the container C1. The photodiode PD3 of the photocoupler PC3 on the sap circuit and the photodiode PD4 of the photocoupler PC4 on the discharge circuit are turned on and off mutually by the control signal from the CPU22. When the telephone line 5 is not disconnected and the line voltage is normal, the photodiode PD3 of the charging circuit is turned on and then the phototransistor PT3 is also turned on. During this conduction period, the capacitor C1 is charged by the very small current generated by the resistor R7 via the line voltage. Then, when the photodiode PD4 on the discharge circuit is turned on, and then the phototransistor PT4 is also turned on, the capacitor C1 is discharged through the discharge resistor R8. This discharge current turns on the photodiode PD5 and the phototransistor PT5 of the output photocoupler PC5. When C P U 2 2 detects that the photoelectric crystal PT5 is on during discharge (when the photoelectric crystal P T 4 is on), it determines that the telephone line is not disconnected. Conversely, when the telephone line is disconnected, no wired voltage is present. Therefore, even if the photodiode PD3 on the charging circuit is turned on, the capacitor C1 is not charged, so it is discharged -1 1-This paper scale is applicable to the Chinese National Standard (CNS) Α4 specification (210Χ297 mm) — γ — installed --- -.-- Subscribe ------ ^ Travel (please read the precautions on the back before filling in this page) · Printed by the Beigong Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs ^ 32565 ΑΊ Β7 V. Description of the invention (10) During this period, the output photoelectric crystal PT5 is not turned on. During the discharge period of CPU22, if the P5 body crystal enters the electricity and enters the light, the outgoing output will flow out of the c line detection. If there is a 5-line phone in the case of Bingshengfa, it will be judged to conduct real-time conduction.
