Accompanying drawing explanation
Fig. 1 is the structural representation of the alarm monitor of the specific embodiment of the invention.
Embodiment
As shown in Figure 1, alarm monitor of the present invention comprises colleting alarming signals module 101, alarm 102 and concentrated alarm interface module 103.
Wherein, be arranged on described in alarm signal photoelectricity collecting unit 101 in SDH equipment frame, colleting alarming signals module comprises the first photoisolator, gather the alarm signal in SDH equipment by the first photoisolator, the alarm signal of SDH equipment is sent by light-emitting device in SDH equipment (such as light-emitting diode).SDH equipment frame is provided with the alarm indicator of different stage, and when there is alarm, information is by alarm indicator (HLCP-H100) luminescence instruction, and different alarm levels is indicated by different indicator lights.As shown in the figure, have 8 light-emitting diodes in HLCP-H100, in alarm panel circuit, they are connected in series, when there being alarm signal to produce, in corresponding alarm indicator, 8 light-emitting diodes are lighted simultaneously, and the drive current of each light-emitting diode is about 10mA.
Colleting alarming signals module 101, by the connection with alarm indicator on the panel module, obtains the information of above-mentioned different alarm level.Particularly, as shown in the figure, colleting alarming signals module 101 directly gathers the signal of telecommunication from the light-emitting diode as warning light, and changes the signal of telecommunication of position proper level by the first photoisolator.
Photoisolator (optical coupler, OC), also known as optical coupler, is called for short optocoupler.Photoisolator take light as the media transmission signal of telecommunication, has good buffer action to input, the output signal of telecommunication.Photoisolator is generally made up of three parts: the transmitting of light, the reception of light and signal amplify.The signal of telecommunication of input drives light-emitting diode, makes it the light sending certain wavelength, is received and produce photoelectric current by photo-detector, then exports after amplifying further.This completes the conversion of electrical-optical-electricity, thus play the effect of input, output, isolation.Owing to isolating mutually between optical coupler input and output, electric signal transmission has the features such as one-way, thus, has good electrical isolation capabilities and antijamming capability.
In an application of the invention, the application of photoisolator not only make use of its noiseproof feature, more importantly, avoids complicated and diversified transport communication protocol, transmits the alarm signal of plurality of devices, monitor.
After alarm signal being undertaken by photoisolator gathering in collecting unit module 101, changing, the alarm 102 being connected to photoisolator output produces warning message according to corresponding level.
Alarm 102 is electrically connected with alarm termination, for generation of warning message.Alarm 103, for sending warning message to control centre, carries out corresponding treatment measures to remind operating personnel.Alarm 102 can be various applicable alarm devices, and preferably, alarm 102 is loud speaker.
Alarm interface module 103 is concentrated to be electrically connected with alarm signal photoelectricity collecting unit, and, can be connected with multiple alarm signal photoelectricity collecting unit.Concentrate alarm interface module 103 preferably also to comprise the second photoisolator, by described second photoisolator, after alarm signal being resolved, be sent to integrated network management system.Concentrated alarm interface module 103 can be the control centre of such as remote computer.Described second photoisolator can adopt the photoelectric device identical with the first photoisolator.
Selectively, alarm monitor of the present invention also comprises interface module 104, and described colleting alarming signals module is by interface module 104 and concentrated alarm interface model calling.Interface module 104 can be the line interface of such as interface box.
Although the present invention is described by above-mentioned preferred implementation, its way of realization is not limited to above-mentioned execution mode.Should be realized that: when not departing from purport of the present invention, those skilled in the art can make different changes and amendment to the present invention.
