A kind of fiber cable cross connection box supervising device
Technical field
The utility model relates to the supervising device of the supervising device of outdoor case body equipment, particularly a kind of fiber cable cross connection box.
Background technology
Fiber cable cross connection box is a kind of handing-over equipment that optical cable Cheng Duan, jumper connection are provided for trunk layer optical cable and wiring layer optical cable for the optical fiber Metropolitan Area Network (MAN).Behind the optical cable leading in cable cross-connecting box, through fixing, termination, join fibre after, use jumping fiber that trunk layer optical cable and wiring layer optical cable are communicated with.
Fiber cable cross connection box is installed in the open air usually, and for guaranteeing the performance of its internal unit and device, fiber cable cross connection box needs to support weather and the bad working environment that is subjected to drastic change.Its casing need have the performance of aspects such as good waterproof, protection against the tide, dustproof, the insect-pest plague of rats, has suitable temperature, humidity to guarantee box house, and can prevent dust and prevent entering of worm mouse.
Yet there is not real-time monitoring equipment in existing fiber cable cross connection box, is to make regular check on to realize by the maintainer to the monitoring of box house performance.The decline of its cabinet characteristic, be difficult in time be found, usually have only and make regular check on by the time or during equipment reporting for repairment after destroyed, could find and handle, often missed best servicing time, the casing management is very passive, in case break down, cause systemic breakdown easily, bring tremendous influence and economic loss.
The utility model content
The utility model is intended to provide a kind of device that fiber cable cross connection box is monitored in real time, in order to can in time find and handle the fault of fiber cable cross connection box.
Fiber cable cross connection box supervising device described in the utility model comprises:
Sensor unit is used for gathering fiber cable cross connection box box house environmental parameter, comprises the temperature sensor, humidity sensor and the light intensity sensor that are installed in box house; Temperature sensor, humidity sensor and light intensity sensor are placed in the zone between casing distribution area and the casing top cover;
Clock unit is used for providing clock signal to control module;
Control module is connected with each sensor of sensor unit, presses the parameter in the clock signal timing read sensor unit, simultaneously analog signal conversion in the environmental parameter of each sensor unit output is become digital signal;
Radio communication unit is connected with control module, and the digital signal that control module is exported sends to network;
Electric battery is connected with control module, powers to control module.
Fiber cable cross connection box supervising device described in the utility model, control module can regularly will be arranged in the environmental parameter that temperature, humidity, light intensity sensor in the sensor unit in the casing detect output and change into digital signal, and it is sent to network by radio communication unit, the network download data can be passed through in the monitoring side, in time understand the environmental aspect in the fiber cable cross connection box, thereby realize the real-time monitoring to fiber cable cross connection box, in time understand the situation of fiber cable cross connection box inside, when the fiber cable cross connection box intrinsic parameter is unusual, can advanced processing.It can avoid fault to take place to the very active of management of casing to a great extent, and significantly reducing for some reason, barrier causes systemic breakdown, influence and the economic loss avoiding so bring.Simultaneously, affiliated monitoring management apparatus is by battery-powered, and it does not need to arrange supply line's leading in cable cross-connecting box, and it is very simple to connect up.
Description of drawings
Fig. 1 is the synoptic diagram of fiber cable cross connection box supervising device;
Fig. 2 is the scheme of installation of fiber cable cross connection box supervising device.
Embodiment
As Fig. 1, Fig. 2, a kind of fiber cable cross connection box supervising device, temperature sensor, humidity sensor 3 and light intensity sensor 4 have been settled in zone between the distribution area 2 of its casing 1 inside and the top cover 10 of casing, are used for gathering temperature, humidity and light intensity in the casing respectively.Introducing district 5 at the cable of the inside bottom of casing 1 distinguishes 6 position along separate routes a little less than light and also is provided with water sensor 7, when box sealing is relatively poor, when having rainwater to enter into casing, the water sensor of bottom half can in time collect casing and be subjected to the water logging signal parameter when the water-soaked cable be introduced the relevant position in district.In addition, also be provided with vibration transducer on the inwall of casing, when casing is subjected to external force collision or beats the generation vibration, but its same instantaneous acquiring is to corresponding vibration signal parameter.Temperature sensor, humidity sensor all is connected with control module with sensor units such as light intensity sensors, the above-mentioned environmental parameter that each sensor of clock signal read sensor unit that control module provides according to clock unit collects, and these the analog signal conversion of environmental parameter become digital signal, radio communication unit by being connected with control module again, the digital signal of the environmental parameter of control module output is sent to network, the monitoring side is again by network download environmental parameter of monitoring sometime in the casing, thereby realizes the real-time monitoring to casing.
Described fiber cable cross connection box supervising device also can arrange storage unit, and this storage unit is connected with control module, is used for the digital signal of temporary control module output, and control module regularly sends to network with the digital signal of storage unit by radio communication unit.By the setting of storage unit, control module needn't be in real time transmitting digital signals incessantly, and Data transmission intermittently, thus reduce the treatment capacity of control module, improve runnability.
Described fiber cable cross connection box supervising device also can arrange electronic lock, and described electronic lock comprises radio frequency module for reading and writing and the intelligent door lock that is connected with control module, and storage unit is stored the mandate card number in advance; The card number that reads when the radio frequency module for reading and writing when authorizing card number consistent, the unlatching of control intelligent door lock; When the card number that reads and mandate card number were inconsistent, intelligent door lock kept locking state, and control module sends alerting signal to network.
Described sensor unit also can comprise the vibration transducer that is installed on the cabinet wall, whether monitors casing through being impacted by arranging of vibration transducer.
Described sensor unit, also can comprise water sensor, water sensor is arranged on box inside bottom cable and introduces district 5 and distinguish 6 position along separate routes a little less than light, whether can in time understand casing by the setting of water sensor leaks, leaking when causing water logging, can in time handle, avoid accident to take place.
Water sensor is preferably disposed on distinguishes 10 centimetres position along separate routes a little less than light, it can either avoid false alarm, can in time reflect the water logging situation again.
In order to prevent accident power-off, the environmental parameter that causes control module to read is lost, this supervising device arranges storage unit, this storage unit is connected with control module, the digital signal that is used for storage control unit output, when switching on again after the outage even meet accident, control module still may be read into the environmental parameter of the preceding storage unit that is kept at of outage, in addition, by the setting of storage unit, control module need not each environmental parameter that constantly reads is uploaded incessantly in real time, but control module is regularly uploaded the data that storage unit is stored by clock unit, thereby further reduce power consumption, the serviceable life of extension fixture.
