Background technology

Present stage is very universal at the on-the-spot pressure unit of industrial process automation; Monitoring industrial process pressure environment; Make various decision-makings by central control room according to data,, help enterprise to carry out the safety guarantee of the person and property aspect to guarantee the normal reliable operation of equipment.The industrial instrument communication aspects, through years development, HART has become the true industrial standard of global intelligence instrument.Yet the HART pressure unit of present stage, main is main with wired HART still, and measured value also can only write down transmission through storage medium or wired mode.If use numerous instrument terminal, just can not intelligent networking write down measured value automatically, intelligence is carried out large-scale data analysis; Simultaneously wired mode can make that circuit is loaded down with trivial details, can not self diagnosis and both-way communication, can not in time pinpoint the problems; Transmission range is not long, increases cost again.And wireless HART is exactly a kind of wireless mesh type network communication protocol of process automation Application Design that is specially.Therefore designing a kind of wireless HART transmitter, to replace the method for present wired HART manometer be feasible.

Summary of the invention

The utility model is the loaded down with trivial details problem of HART pressure unit transmission line to present stage, has proposed a kind of wireless HART intelligent pressure transmitter based on XDM2510H, adopts four joint rechargeable battery power supplies; Main controller controls was monitored the on-the-spot pressure data of control in real time, but the scene switch is selected LED to show and have to report to the police and pilot lamp the self-diagnosable operational factor; This transmitter outside need not other leads; Intelligence is succinct convenient, and range can be set, and monitoring parameter and the low-power consumption of self-operating parameter simultaneously is stable down to send to central control room through the wireless HART network rapidly; Carry out the double-direction radio communication, supply the keeper to monitor control and use.

The technical scheme of the utility model is: a kind of wireless HART intelligent pressure transmitter based on XDM2510H comprises master controller, pressure transducer, operational amplifier, signal processing unit and minimum system circuit, memory cell; Man-machine interaction unit; XDM2510H module, man-machine interaction unit comprise real-time pilot lamp, the KEY keyboard unit; The LCD circuit, said pressure transducer, operational amplifier, signal processing unit send master controller with pressure signal after connecting successively; Said man-machine interaction unit is connected with master controller, and KEY keyboard unit input setting operation signal is gone into master controller, outputs to real-time pilot lamp and LCD circuit after the master controller deal with data and shows; The minimum system circuit is the auxiliary circuit of master controller work; Said master controller carries out wireless telecommunications through the XDM2510H module and the external world.

Said minimum system circuit comprises power supply, and crystal oscillator resets and download circuit, the optional rechargeable battery of said power supply, and download circuit can be supported the transmitter upgrading.

The beneficial effect of the utility model is: the utility model is based on the wireless HART intelligent pressure transmitter of XDM2510H, and whole transmitter is succinctly easy to use; Unmanned work need not the external connection line road, and transmission range is long; Not limited by the industrial automation hardware environment, central control room can be checked the operation duty of each link transmitter at any time, uses numerous transmitters; Automatically write down measured value from networking, carry out large-scale data analysis.
