Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined.

The embodiment is as follows: referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a road junction video and long-range centralized control system, includes signal building, crossing room and crossing, the signal building includes the remote control case, the crossing room includes the crossing control box, still installs the manual control box on the crossing control box, and the crossing includes camera, alarm machine, gate machine, and the remote control case passes through optical fiber modem, optic fibre, communication line and links to each other with the crossing control box.

The signal building and the crossing room are both provided with remote video monitoring equipment, and a display on the remote video monitoring equipment is connected with a camera of each outdoor crossing through a video optical transceiver, an optical fiber, a cable and a video line. And acquiring real-time pictures of the outdoor crossing, and transmitting the pictures to the industrial personal computer and the display through corresponding interfaces so that indoor operators can observe the field conditions.

The crossing control box is connected with the alarm machines and the gate machines on all the crossings on site through the optical fiber modem, the optical fiber, the communication line and the crossing control host. The crossing control box controls the crossing barrier machine by receiving the instruction sent by the alarm machine, and simultaneously, the manually controlled crossing also receives the crossing alarm instruction through the control box to give alarm information to the crossing host (the original interlocking crossing and the sensor crossing do not change the original alarm mode;
