Summary of the invention
The utility model technical matters to be solved provides that a kind of reasonable in design, transmission loss are few, strong interference immunity, to water quality according to the little electric pole type water-temperature water-level sensor of lazyness property.
It is this electric pole type water-temperature water-level sensor that the utility model solves the problems of the technologies described above the technical scheme that is adopted; Comprise sensor body and measurement and control instrument; Its design feature is: described sensor body links to each other with wire-controlled apparatus through pickup wire; Said wire-controlled apparatus links to each other with measurement and control instrument through the measurement and control instrument line; Be provided with control module, half-duplex transceiver module in the said wire-controlled apparatus; Be provided with measurement module, DC-DC power module, controller power supply supplying module in the said measurement and control instrument, said control module links to each other with sensor body, half-duplex transceiver module, measurement module, DC-DC power module respectively, and said DC-DC power module links to each other with controller power supply supplying module.
Also be provided with anti-thunderbolt module in the said measurement and control instrument of the utility model, described anti-thunderbolt module links to each other with control module.
The length of the said pickup wire of the utility model is 16cm.
The utility model is compared with prior art and is had the following advantages and effect: 1, simple control mode, digitizing transmission, transmission technology; 2, anti-power frequency is disturbed; 3, reduce the electric pole type level sensor to water quality according to lazyness property; 4, half-duplex transmission data message,, make the system data transmission in time more reliable and anti-interference; 5, because of measurement mechanism as much as possible near measure field, so can strengthen measuring reliability, reduce measuring error; 6, because of above-mentioned measuring method improves doing electrode sensor, but the production system of sensor body technology not Fa Ren can change, so cost can reduce, simultaneously performance increases.7, distinctive anti-thunderbolt module makes product safe in utilization out of doors more relieved.
