Abstract

The utility model relates to an automatic paging alarm, which can be used for converting an alarm signal to the lifting set and the dialing functions of a telephone set and can also be used for sending an alarm cipher set by a host to a BP machine carried by the host through a paging station. The utility model is composed of a sensing part, a timing driving part and a telephone interface part. The utility model has small volume and low electricity consumption and is suitable for being hidden. By making use of modern communication apparatuses of the telephone set and the BP machine, the utility model has the advantages of high sensitivity, quick action, wide alarm range, far distance, etc.

Description

Automatic paging alarm for telephone BP machine interconnection network

The utility model relates to a kind of device that remote-wireless is reported to the police that is used for, and this device is specially adapted to have room, the office of telephone set, the warning system in warehouse, does far distance automatic radio alarming.

Warning device at present commonly used mostly is the wired alarming device greatly, and its alarm range and distance all are restricted, particularly when owner when establishing alert place, alarm has just lost effect, so is necessary to adopt a kind of remote-wireless warning device.

The purpose of this utility model is that a kind of machine of carrying and dial feature that alarm signal can be converted to telephone set will be provided, alarm cipher with owner's setting, send the owner who carries beeper to by paging station, automatic paging warning device simple in structure, easy to install.

The purpose of this utility model is achieved in that this device is by transducing part, the timing drive part, and telephony interface part three parts are formed, and wherein transducing part comprises transducer, transmission line, plug; Regularly drive part comprises socket, and printed circuit board (PCB), relay, accessory power outlet, mains switch, the battery of integrated circuit and Resistor-Capacitor Unit is housed; Telephony interface partly comprises output plug, transmission line and by the former circuit of carrying machine mechanism circuit reconfiguration of telephone set.Transducer links to each other integrated circuit (IC), capacitance-resistance original paper R by transmission line, plug with socket on the machine shell panel ₁, R ₂, C ₁, C ₂Together pack in the casing with battery in the back that is connected with relay, mains switch, socket and accessory power outlet are installed in respectively on the panel of casing, and telephone set links to each other with accessory power outlet by transmission line, output plug.

Its operation principle is, transducer is touched instantaneous short circuit by the people, and by transmission line, 6,8 pin that make IC are connected with ground moment and obtained a negative pulse, and two timers that are made of IC are activated simultaneously, and the 5th pin output of IC makes relay J ₁Action makes the circuit connection of being carried machine mechanism circuit reconfiguration by telephone set by transmission line, makes telephone set enter the dialing tone state, and the duration is by R ₁, C ₁Decision (setting-up time is that telephone set reverts to original holding state behind 20 seconds, 20 seconds) the 9th pin output of IC simultaneously makes relay J ₂Action, by the redial key circuit momentary connection of transmission line with telephone set, its duration is by R ₂, C ₂Decision (be set at 2 seconds, automatic disconnection after 2 seconds), at this moment, dial number last time that stores in the telephone set is promptly transferred to the carrier of (this number is set to paging station's number+beeper number+alarm cipher) beeper can hear warning call sound immediately and see alarm cipher.

The utility model adopts integrated circuit and miniature relay, volume is little, power consumption is low, be fit to hidden placement, utilized this modern communication network of telephone set and beeper to realize the warning of phone beeper networking automatic paging, have highly sensitive, be swift in motion, alarm range is wide, advantages such as distance, and do not participate in the telecommunication transmission signal, do not influence the normal operation and the use of telephone set.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is phone beeper networking automatic paging warning device perspective view.

Fig. 2 is phone beeper networking automatic paging warning device circuit theory diagrams.

Describe the operating position of concrete structure of the present utility model in detail below in conjunction with accompanying drawing, this device is by transducing part, drive part regularly, and telephony interface part three parts are formed, and wherein transducing part comprises transducer 10, transmission line 16, plug 15; The timing drive part comprises socket 8, printed circuit board (PCB) 5, relay 6,11 accessory power outlets 12, mains switch 7, the battery 4 of integrated circuit and Resistor-Capacitor Unit is housed, this part is to be made of 555 time-base circuits, IC is the NE556 dual time-base ic, pin 7 is common Vss, and pin 14 is the anodal Vcc of public power, and pin 2 pin 12 are threshold value input TH, pin 3 pin 11 are control end VC, pin 6 pin 8 are to trigger input TR, and pin 4 pin 10 are master reset end MR, and pin 5 pin 9 are output end V ₀, pin 1 pin 13 is discharge end DIS.The first half control relay J of this circuit ₁Action starts phone and carries machine circuit, R in the circuit ₁, C ₁Be the timing resistor and the electric capacity of IC first half, the latter half trigger relay J of circuit ₂Action, R ₂, C ₂Be the timing resistor and the electric capacity of IC latter half; Telephony interface partly comprises output plug 9, transmission line 17, by the former circuit 13 of carrying machine mechanism circuit 14 reconfigurations of telephone set; Transducer 10 links to each other with socket 8 on the machine side plate 2 by transmission line 16, plug 15, integrated circuit, pack in the casing 1 together with the battery case 3 that battery 4 is housed in the Resistor-Capacitor Unit back that is connected with relay 6,11, mains switch 7, socket 8 and accessory power outlet 12 are installed in respectively on the panel 2 of casing, and the circuit of forming after accessory power outlet 12 and plug 9 are pegged graft 13 is equivalent to circuit 14.During use, set transmission line and plug, socket earlier, turn on the power switch, be provided with to report to the police with telephone keypad simultaneously and notify from a phone call password, the automatic paging of phone beeper networking at this moment warning device just enters operating state, touches transducer as the people and makes its short circuit, just can trigger automatic connection of timing driving circuit and carry machine circuit, and transfer to the number that sets in advance, and make beeper receive call, telephone set recovers holding state automatically after 20 seconds.
