Detailed Description
As shown in fig. 1, the alarm monitoring device of the present invention includes an alarm signal collecting module 101, an alarm 102 and a centralized alarm interface module 103.
The alarm signal photoelectric acquisition unit 101 is installed on a chassis of the SDH device, and the alarm signal acquisition module includes a first photoelectric isolator, and acquires an alarm signal on the SDH device through the first photoelectric isolator, where the alarm signal of the SDH device is sent by a light emitting device (e.g., a light emitting diode) on the SDH device. Alarm indicating lamps of different levels are arranged on the SDH equipment rack, when an alarm occurs, information is indicated by the light emission of the alarm indicating lamps (HLCP-H100), and different alarm levels are indicated by different indicating lamps. As shown, there are 8 LEDs in the HLCP-H100, which are connected in series in the alarm panel circuit, and when there is an alarm signal generated, 8 LEDs in the corresponding alarm indicator light are simultaneously lighted, and the driving current of each LED is about 10 mA.
The alarm signal acquisition module 101 is connected to the panel alarm indicator light module to obtain the information of the different alarm levels. Specifically, as shown in the figure, the alarm signal collection module 101 directly collects an electrical signal from a light emitting diode as an alarm signal lamp, and converts the electrical signal of an appropriate level through a first opto-isolator.
An optical isolator (OC) is also called an optical coupler, which is called an optical coupler for short. The photoelectric isolator transmits electric signals by taking light as a medium, and has good isolation effect on input and output electric signals. The optoelectronic isolator generally consists of three parts: light emission, light reception and signal amplification. The input electric signal drives the light emitting diode to emit light with a certain wavelength, the light emitting diode is received by the optical detector to generate optical current, and the optical current is further amplified and then output. This completes the electric-optical-electric conversion, thereby playing the role of input, output and isolation. Because the input and the output of the optical coupler are isolated from each other, the electric signal transmission has the characteristics of unidirectionality and the like, thereby having good electric insulation capability and anti-interference capability.
In the application of the invention, the application of the photoelectric isolator not only utilizes the anti-interference characteristic thereof, but also avoids complex and various transmission communication protocols and transmits and monitors the alarm signals of various devices.
After the acquisition unit module 101 acquires and converts the alarm signal through the photoelectric isolator, the alarm 102 connected to the output end of the photoelectric isolator generates alarm information according to the corresponding level.
The alarm 102 is electrically connected to the alarm wiring device for generating alarm information. The alarm 103 is used for sending alarm information to the control center to remind an operator to perform corresponding treatment measures. The alarm 102 may be any suitable alarm device, and preferably the alarm 102 is a speaker.
The centralized alarm interface module 103 is electrically connected to the alarm signal photoelectric acquisition units, and may be connected to a plurality of alarm signal photoelectric acquisition units. The centralized alarm interface module 103 preferably also includes a second optical isolator, through which the alarm signal is transmitted to the integrated network management system after being analyzed. The centralized alert interface module 103 may be, for example, a control center of a remote computer. The second optoelectronic isolator can adopt the same optoelectronic device as the first optoelectronic isolator.
Optionally, the alarm monitoring apparatus of the present invention further includes an interface module 104, and the alarm signal collecting module is connected to the centralized alarm interface module through the interface module 104. The interface module 104 may be a line interface such as an interface box.
Although the present invention has been described in connection with the preferred embodiments, its mode of implementation is not limited to the embodiments described above. It should be appreciated that: various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention.
