Technical field
The invention belongs to electrical equipment transmission line of electricity on-line monitoring field, refer more particularly to a kind of rainwater responsive type temperature and humidity sensing device on the filthy on-line monitoring equipment of light sensing.
Background technology
External insulation pollution degree monitoring on transmission line of electricity, light sensing is a kind of common method.By in conjunction with temperature and humidity sensing and Fibre Optical Sensor, detect multi-group data combined calculation every day, utilize trained mathematical model, the pollution degree of insulator can be calculated.Use wireless data transmission technology, can realize carrying out remote on-line real time monitoring to the insulation pollution degree of working line.Wherein used mathematical model trains gained by contrast test data, contrast test is carried out at transmission line of electricity scene, make insulator contamination synchronous with sensor, and synchro measure, directly establish the relation that the change of both the optics of sensor and humiture detection amount changes with insulator dirty degree, usually can obtain pollution degree more accurately.
Light sensing power transmission and transformation equipment filth on-Line Monitor Device, is generally made up of a few part such as light sensing, control module, power supply and supply line, temperature and humidity sensing etc.Control module be responsible for the collection of the job control of other a few part and data, process, with send, power supply is powered for all the other each several parts, most use solar recharging mode.Device is generally integrated design, is installed to electric power line pole tower cross-arm and carries out real time on-line monitoring.
" the close on-line monitoring system of optical sensor power transmission and transforming equipment salt " (patent No.: 201110231489.X).Within the system, in order to protect humiture detector, its position being hidden into the region avoiding rainwater to drench, so then cannot collecting the information of whether raining.Due to the otherness of optical sensor and insulator itself, it is inconsistent that pollution degree when rainy changes relatively compared with situation about not raining, this point needs information and uses mathematical model to solve, and therefore equipment collects the information of whether raining is the basal needs that model could carry out appropriate training.High humility is shown as, then for the humidity sensor qualitative detection information of raining provides possibility based on suddenling change when humidity sensor and contacting rain water.
Summary of the invention
Technical matters to be solved by this invention is the deficiency for above-mentioned existence, there is provided a kind of to make sensitive face and rainwater that certain contact occur and detect its humidity caused to change, there are the humiture data of discrimination to input for multiprecision arithmetic model provides to rainy weather, improve the rainwater responsive type temperature and humidity sensing device of the computational accuracy of the filthy monitoring equipment of light sensing on the rainy date.
The technical solution adopted for the present invention to solve the technical problems is:
Rainwater responsive type temperature and humidity sensing device, it is characterized in that: comprise the Temperature Humidity Sensor structural member below the solar panels being fixed on on-line monitoring equipment, Temperature Humidity Sensor structural member side is provided with Temperature Humidity Sensor, Temperature Humidity Sensor is facing to outside equipment, and vertically place, and being covered with rainwater diversion mechanism at Temperature Humidity Sensor, rainwater diversion mechanism is the tubular structure vertically arranged; Temperature Humidity Sensor structural member opposite side is provided with fixture, and fixture is rod-like structure, and is provided with control module and power supply that Temperature Humidity Sensor is connected to on-line monitoring equipment by wire.

In such scheme, described rainwater diversion mechanism shape is the combined shaped of upper and lower two concentric thick ring-types and outside flat board, two thick rings link together by flat board, rainwater is guided to pass through from two thick rings, reach and make rainwater traffic direction comparatively be parallel to sensitive face, and do not produce the effect of ponding.Outside flat board mechanical protection is provided, and under windy conditions can be stoped rainwater to the immersion of sensitive face.
Principle of the present invention is, outside Temperature Humidity Sensor, a rainwater diversion mechanism is installed, this mechanism's role is guided by the rainwater fallen from top to pass through from the sensitive face of Temperature Humidity Sensor, and partly contact with sensitive face, all rainwater entering deflector finally all spill from its lower opening.Two aspects are mainly considered in the design of this deflector: sensor probe should be enable directly to touch rainwater, possess rainwater susceptibility; Meanwhile, ensure the less ponding in temperature and humidity sensing face, also horizontal mechanical protection effect is played to sensor.
Filthy monitoring equipment pollution degree numerical value carries out calculating gained by enabling algorithm model after gathering optical parameter and humiture ED every day to data, and be sent to manual monitoring background terminal by communication.The required data used of algorithm model training are tested in filthy on-the-spot contamination synchronous with insulator and measure the correlation data of gained respectively for monitoring equipment.Model, through computer aid training, sets up the relation that institute's photometric parameter and humiture data and insulator artificial measure pollution degree.Use the filthy monitoring equipment of above-mentioned temperature and humidity sensing device, calculate data and compare original structure, the computational accuracy on the date of raining will be significantly improved.
Beneficial effect of the present invention is:
Apparatus of the present invention have the humiture data of discrimination to input for multiprecision arithmetic model provides to rainy weather, can improve the computational accuracy of the filthy monitoring equipment of light sensing on the rainy date.
Accompanying drawing explanation
Fig. 1 is the structural design schematic diagram of the embodiment of the present invention;
Fig. 2 is the working state structure figure of the embodiment of the present invention;
