Abstract
The utility model relates to a patrol checker for optical cable lines, which comprises a Mo-dem circuit, and a switching circuit, wherein, the switching circuit is connected with the Mo-dem circuit. An input and an out terminals of the utility model are connected with plug-in interfaces of a mobile phone; a control terminal of the switching circuit is connected with a terminal of the Mo-dem. The utility model has the technical proposal that the utility model can utilize the mobile phone and a network to realize data collection, and management and monitoring for the patrol work. When the utility model particularly works, a center control circuit firstly sends signals to a GPS mobile phone, the mobile phone is switched on, the Mo-dem can utilize a public telephone network to send data and other signals to central administration by the public telephone network, and thereby, data transmission is finished, and situations can be controlled by the central administration.
Description
The utility model is a kind of lightguide cable link inspection device.
For guaranteeing the unimpeded of lightguide cable link, need often it to be checked and go the rounds.Traditional maintenance management mode is to specify markstone place to do sign or list according to production plan to circuit by the track walker, administrative staff check that to the scene (sampling observation) indicates or list and protect line propaganda record, because characteristics a little many, wide, line length that lightguide cable link has, thereby will spend great amount of manpower and material resources and time supervision and oversight track walker's work quality, but effect is still not ideal enough.
The purpose of this utility model is: design a kind of being convenient to the management of the touring work of lightguide cable link and the lightguide cable link inspection device of its data acquisition.
The utility model comprise central control circuit and connected GPS data in mobile phone line output terminal, and the Modem circuit between change-over circuit.
The technical solution of the utility model is to utilize mobile phone and network to realize data acquisition and to work of patrolling and examining and management and supervision.As shown in Figure 1, when concrete operation, central control circuit at first makes its connection to the GPS mobile phone sending signal, utilizes public telephone network to send other signals such as data to administrative center by Modem again, thereby finish the automatic operation of transfer of data, and administrative center grasps situation thus.
In the utility model, can realize by modes such as timesharing controls by central control circuit, also can finish by level shifting circuit with the GPS mobile phone with the connection procedure of Modem.Said power conversion circuit can be following structure:
It comprises 7 NAND gate and a level transferring chip, the syndeton of they and central control circuit is as follows: 1 pin of TXD chip termination U3A and 4 pin of U3B, 2 pin of U3A connect 13 pin of chip U3D and the R2OUT pin of chip U4,12 pin of the output termination U2D of U3A.13 pin of U2D connect the P11 end of U1, its output termination U4 and T1IN end.5 pin of U3B are connected with 12 pin of U3D, connect 1,2 pin of U2A after the 11st pin output of U3D, and its output the 3rd pin connects the RXD pin of cpu chip U1.Output the 6th pin of U3B connects the R1OUT pin of U4 and the 5th pin of U2B, and the P12 pin of U1 meets the 4th of U2B and fails, 9,10 pin of the 6th pin output retaining U3C of U2B, the output termination connector of U3C.R1IN, the R2IN of U4 connect connector, and the T1OUT of U4 and T2OUT connect connector after holding the resistance of connecting respectively.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is the flow chart of the utility model user mode;
Fig. 2 is the line map of the utility model embodiment central control circuit and level shifting circuit;
Present embodiment comprises the cpu chip U1 that has crystal oscillator clock circuit and reset circuit, the connector that connected Modem circuit and level shifting circuit and level shifting circuit, Modem circuit are connected with the GPS mobile phone, Modem circuit and adopt existing circuit form with being connected of CPU wherein is here no longer to its concrete narration.The level shifting circuit of present embodiment and with being connected as shown in Figure 2 of cpu chip U1,1 pin of the TXD chip termination U3A of U1 and 4 pin of U3B, 2 pin of U3A connect 13 pin of chip U3D and the R2OUT pin of chip U4,12 pin of the output termination U2D of U3A.13 pin of U2D connect the P11 end of U1, its output termination U4 and T1IN end.5 pin of U3B are connected with 12 pin of U3D, connect 1,2 pin of U2A after the 11st pin output of U3D, and its output the 3rd pin connects the RXD pin of cpu chip U1.Output the 6th pin of U3B connects the R1OUT pin of U4 and the 5th pin of U2B, and the P12 pin of U1 meets the 4th of U2B and fails, 9,10 pin of the 6th pin output retaining U3C of U2B, the output connection interface of U3C.The R1IN of U4, R2IN connection interface, the T1OUT of U4 and the T2OUT end connection interface behind the resistance of connecting respectively.The interface of the interface of level shifting circuit and Modem circuit is connected on the same mobile phone connector in the present embodiment.
