Description

A kind of intelligent signal isolating transmitter

Technical field

The utility model relates to signal isolating transmitter technical field, is specially a kind of intelligent signal isolating transmitter.

Background technology

Signal isolating transmitter is the industry spot for electricity isolation observing and controlling, power monitoring, medical treatment electronic equipment, the isolation of analog quantity 4-20mA signal and collection, the aspects such as the long line undistorted transmission of remote signal, current industrial signal isolating transmitter adopts analog signal transmission technology mostly, for Nonlinear thermal galvanic couple, the signals such as thermal resistance adopt simulation curve fitting technique to realize change and send transfer function, the sensor change number of the delivering letters input style so just causing this type is single, precision is low, easily by temperature drift effects, rig-site utilization is replaced very loaded down with trivial details, there is no communication function simultaneously, such field wiring is very many, easy introducing signal disturbing, when local scene goes wrong, the action protection of local alarm relay can not be carried out in time, for this reason, we propose a kind of intelligent signal isolating transmitter.

Utility model content

The purpose of this utility model is to provide a kind of intelligent signal isolating transmitter, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme: a kind of intelligent signal isolating transmitter, comprise load module and power module, the input end of the output terminal electrical connection signal gain amplifier module of described load module, the input end of the output terminal electrical connection AD converter of described signal gain amplifier module, the output terminal electrical connection photoelectric isolation module of described AD converter, the input end of the output terminal electrical connection digital microprocessor of described photoelectric isolation module and power module, the output terminal of described digital microprocessor is electrically connected with alarm module and Phototube Coupling processing module, the output terminal of described Phototube Coupling processing module is electrically connected with RS458 communication module and DA changes output module, the output terminal of described alarm module is electrically connected with local relay protection module, described DA changes the input end of output module electrical connection format converter, the output terminal of described format converter is electrically connected with analog signal output module.

Preferably, described power module is 24 volts of insulating power supplies.

Preferably, the RS458 connection of described RS458 communication module is 2.

Preferably, described alarm module comprises local alarm relay

Compared with prior art, the beneficial effects of the utility model are: this intelligent signal isolating transmitter adopts embedded scm technology, solve the problem that a transmitter realizes the omnipotent input of whole industry spot signals, such scene is using and is changing very convenient, there is extraordinary interchangeability, can ensure that various linear signal and nonlinear properties freely switch as required, there is the communication function of standard simultaneously, the remote data acquisition of multi signal data can be realized by 2 RS485 connection group station modes, this locality has alarm relay to transfinite defencive function, the action protection of reporting to the police can be realized on the spot when local data transfinites.
