Embodiment
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
Fiber cable cross connection box supervising device of the present invention consists of the following components: 1 is data transmission set (it is example that this example changes serial ports modem with optical fiber), and 2 is the DC-DC power supply adaptor, and 3 is lightning protection for power supply, and 4 is signal picker, and 5 is sensor.Its annexation as shown in Figure 1.
Sensor can have kinds such as temperature sensor, water sensor, door status sensor, inclination sensor; Sensor can be one or more combination of above-mentioned several sensors in specific design.The present invention adopts four kinds of above-mentioned sensor acquisition signals.
Signal picker as shown in Figure 2, has 4 parts, acquisition channel, AD conversion unit, central control unit, IO interface.Acquisition channel can be gathered 8 road analog/digital signals altogether, is the voltage signal of 0-5V or the current signal of 4-20mA, but except 4 monitoring parameters such as cut-in temperature, inclination, door magnetic, water logging, the demand that monitoring parameter increases after can also satisfying.No matter monitoring parameter is simulating signal or digital signal, acquisition channel all is used as simulating signal collection, and the monitoring parameter that collects changes into digital signal by AD conversion unit, and digital signal enters central control unit.Central control unit is done simple processing and judgement to digital monitoring parameter, and then the digital supervision data being sent to optical fiber by the RS422 IO interface changes serial ports modem.
In other embodiment, the acquisition channel of signal picker can be provided with more than one or one, can set as the case may be, is not limited to four above-mentioned acquisition channels.
Optical fiber changes serial ports modem, is used to realize the conversion between the asynchronous serial port electric signal such as light signal and RS232/RS422/RS485.The digital supervision amount is changed near base station and the base station data of light signal delivering to and is sent to Surveillance center together in optical fiber changes serial ports modem.The light signal order that sends by the base station of Surveillance center simultaneously also can be changeed serial ports modem by optical fiber and be changed into asynchronous serial port electric signal such as RS232/RS422/RS485, the arriving signal collector, and signal picker is made corresponding response according to order.
Power unit is made up of lightning protection for power supply and DC-DC power supply adaptor.Total system adopts the DC12V power supply, if fiber cable cross connection box provides DC12V power supply, just passable at lightning protection device of power input serial connection so, if fiber cable cross connection box only provides the DC-48V power supply, also to increase a DC-DC power supply adaptor so in the lightning protection device back, be used for converting DC-48V to DC12V.
As shown in Figure 3, monitoring parameters such as temperature (voltage signal of 0-5V or the current signal of 4-20mA) enter acquisition channel, K1 is a switch, R1 is sampling with high precision resistance (being generally 0.1% precision), if monitoring parameter is the voltage signal of 0-5V, then K1 is an off-state, and monitoring parameter directly enters analog to digital converter AD7895; If monitoring parameter is the current signal of 4-20mA, then K1 is a closure state, and the current signal monitoring parameter changes into the voltage signal monitoring parameter by sampling resistor R1, and the voltage signal monitoring parameter enters analog to digital converter AD7895 again.AD7895 becomes digital signal with monitoring parameter by analog signal conversion, sends into single-chip microcomputer SST89V516.Single-chip microcomputer is simply handled digital signal and is judged, the result is sent.The result becomes the RS422 signal through a RS422 interface chip MAX489 earlier, the result of RS422 signal enters optical fiber changes serial ports modem, optical fiber changes serial ports modem the RS422 conversion of signals is become light signal, in near by optical fiber the result of light signal being delivered to base station and the base station other data be sent to Surveillance center together.
In the foregoing description, if fiber cable cross connection box has laid twisted-pair feeder, as shown in Figure 4.This situation can adopt the mode of RS422/RS485 to carry out data transmission.Because signal collecting device has possessed the RS422/RS485 interface, just can directly carry out data transmission so need not data transmission set.This scheme is applicable to that fiber cable cross connection box is used by existing local telephone network cross-connecting box transformation.(notice that the RS422/RS485 maximum transmission distance is 1000 meters,, need to increase the RS422/RS485 repeater if surpass this distance.)
In the foregoing description,, can adopt wireless transmission method if do not want to take fiber bandwidth, CDMA1X for example, because whole monitoring system is independent of fiber optic cable plant, this scheme is applicable to more increases supervising device to the fiber cable cross connection box in using.As shown in Figure 5, only need that optical fiber is changeed serial ports modem and change CDMA1X wireless module (because CDMA 1X wireless module uses the RS232 interface, so need change the interface IC of signal picker inside into MAX202) into, can realize the effective monitoring of total system.
