V. New description: [New technology field]

An anti-theft dialing device, especially an anti-theft device that can be used to connect a telephone line and a communication device, and can prevent the telephone line from being stolen. [Prior Art]

According to the telephone, the telephone has become a necessity in human life. However, because the wired telephone line is vulnerable to theft by the minded person, the telephone line of the normal user is dialed, and the telephone fee of the user is increasing, which causes the user to bear the financial burden. Therefore, That is to say, there are related operators who are constantly researching the anti-recording device, but at present, the anti-theft device of the city f, and the wiring and the thief of the eye-catcher are all developed and developed, and the anti-theft device used by the manufacturer is used by the side operators. The subject of research and development. [New Content] The main purpose of our work is to test the power level of the telephone line, and whether or not the power outage is misappropriated or destroyed to avoid theft of the telephone line.

In order to achieve the above purposes, the creation anti-theft device is used to connect the telephone line and the 2 device, and the _ _ _ _ system is provided with a local line connector, a multi-frequency interference signal production device, a communication control device, The alarm and the abnormality of the local line are called thieves, wherein: the line connector side is electrically connected to the telephone line. The μ j frequency interference Λ generates 11 lines of threats to the line connection 11 and can send interference signals to the telephone line. The broadcast is connected to the multi-frequency interference signal generator for controlling the operation of the multi-frequency interference signal generator. 3 M432206 The detection device is connected between the local line connector and the controller, and the detecting device is used for detecting the change of the power level of the telephone line, and sending the control signal to the controller, so that the controller is in accordance with the control. The signal activates the multi-frequency interference signal generator. The communication control device is connected between the local line connector and the controller, and the communication control device is used to connect the communication device. When the communication device is used, the communication control device sends a control signal to the controller to make the controller forcibly stop the control. The multi-frequency interference signal generator is activated. The alarm is connected to the controller. When the controller controls the operation of the multi-frequency interference signal generator, the alarm is activated to make the alarm sound. The local line anomaly detector is connected to the local line connector to detect whether the telephone line is damaged. [Embodiment] Please refer to the first figure and the second figure. As can be clearly seen from the figure, the artificial anti-theft device 1 is provided with a local line connector 11 and the local line connector U is connected with a multi-frequency interference signal. The generator 12, the multi-frequency interference signal generator 12 is connected to the controller 13, and the detection device 14 and the communication control device 15 are connected between the controller 13 and the local line connector 11. When the creation is in use, the telephone line 2 is connected to the local line connector u, and the communication device 3 (such as a telephone, a fax machine, a data machine, a switchboard system, etc.) is connected to the communication control device 15, at this time. The detecting device 14 continuously detects the change of the power level of the telephone line 2. In general, when the communication device 3 is in the standby state (On-Hook), the voltage on the telephone line 2 is approximately 48±15% volts DC voltage' and when the communication device 3 is in the use state (Off-Hook), that is, when the communication device 3 and the telephone office line 2 are turned on, the load is generated on the telephone line 2, and the DC power is reduced. 4 M432206

At this time, the voltage on the telephone line 2 is about 5±15% volt DC, and the low voltage will inform the central office to generate a dial tone, ready to receive the dial, therefore, when the detecting device 14 detects the call When the voltage on the line 2 drops, and the communication device 3 is not in use, that is, the telephone line 2 is stolen, and the detecting device 14 sends a control signal to the controller 13 to make the controller 13 turns on the multi-frequency interference signal generator 12, which in turn causes the control of the multi-frequency interference signal generator a to be activated, thereby generating an interference signal to be transmitted to the telephone office line 2 to make the pirate unusable.

Although the communication device 3 is in use, the telephone line 2 will also generate a voltage drop, but the communication control device i 15 will send a control signal to the controller 13 to cause the controller 13 to forcibly stop the control of the multi-frequency interference signal generator 12 to operate. In order to avoid the communication device 3 being unusable; the controller 13 is connected with the alarm device 16, so that the controller can activate the multi-frequency interference, and the alarm will be sounded to warn the telephone line 2 to be stolen. The local line connector 11 of the π dialing device 1 is connected with a local line abnormality detector

When the pirate is broken, if the pirate is damaged, for example, the thief informs the user of the telephone line 2 to cut the side _ _ zero of the telephone line 2, that is, the warning will be issued: create == solve the problem of the conventional technology And missing, its key technology is stolen, line 2 cake, __ office line 2 can be between, convenient for users to use, and no need to change the indoor line. 5 M432206 [Simple description of the diagram] The first diagram is a block diagram of the creation. The second picture is the circuit diagram of this creation. [Main component symbol description] 1.
