utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, there is provided a kind of structure simple, can detection signal transmission line break-make, and display centre machine room side, signal transmission line or station end fault novel remote signal line loopback detection device.
The technical solution of the utility model is: a kind of novel remote signal line loopback detection device, comprise station end, central machine room and control device, PCM access device is provided with in described station end and central machine room, and connected by SDH transmission network between PCM access device, described central machine room comprises distribution area, control device and Central Control Module, described distribution area is connected with the PCM access device in central machine room, described distribution area is connected by serial line interface with Central Control Module, control device is provided with between described serial line interface, described control device is connected with Central Control Module by wireless network.
Described control device comprises processor, signal supervisory instrument, communicator, relay, alarm device, described processor is connected with signal supervisory instrument, communicator, relay, alarm device, is provided with driving circuit and power supply between described processor and relay.Described alarm device comprises pilot lamp and hummer, and described communicator comprises wireless module and serial line interface.
Described station end comprises terminal device, distribution area, controller, and described distribution area is connected with the PCM access device in holding of standing, and the PCM access device in the end of described station is connected by serial line interface with the distribution area in holding of standing, and is provided with controller between described serial line interface.
Described controller comprises MCU module, communication interface modules, miniature relay, and described MCU module is connected with communication interface modules and miniature relay, is provided with driving circuit and power module between described MCU module and miniature relay.
The beneficial effects of the utility model are:
1, the utility model structure simple, just can detection signal transmission line break-make without the need to manually carrying out operation, and display centre machine room side, signal transmission line or stand and hold fault, facilitate the operation of other operating personnel.
2, the utility model can complete the loop back processing being of station end digital channel at central machine room by Long-distance Control, after eliminating central machine room extremely adjusts fault, can directly carry out whole passage loopback test, saving operation maintenance personnel goes to station end to carry out the process of loop back processing being, significantly reduces the processing time of this type of fault.
3, the utility model is arranged in each website digital channel distribution area, each website is utilized substantially to have the feature of redundant channel, load owing to there is no business, redundant channel damage probability is almost 0, thus possess reliability, this passage is only after receiving the control signal that central machine room sends, and controller just sends relevant action, there is no maloperation and cause the consequence of normal channel loopback, and normal condition is to being with service channel without any interference.
4, the utility model is not only when Central Control Module receives the Detection Information not detecting end transmission of arriving at a station with control device, control device is engage relay, the concurrent number of delivering letters connection miniature relay, realize the detection of information conveyance circuit, normal working hours relay and miniature relay be off-state, do not affect Central Control Module to station end detection signal reception.
5, the utility model is provided with pilot lamp and hummer, in central machine room side, signal transmission line or station end fault time, realize alarm, the operation of handled easily personnel.
accompanying drawing illustrates:
Fig. 1 is the anatomical connectivity block diagram of novel remote signal line loopback detection device.
Fig. 2 is the connection block diagram of control device.
Fig. 3 is the connection block diagram of controller.
