Abstract
The utility model relates to a communication protocol converter, in particular to a communication protocol converter capable of converting an HART protocol to a Profibus protocol which is used for data exchange between an on-site instrument complying with the HART protocol, such as a flow meter, a pressure transmitter, a temperature transmitter and the like, and an on-site control system complying with the Profibus protocol. The communication protocol converter is characterized in that the converter comprises an HART protocol interface device, a protocol processing singlechip module, a processing chip module and a Profibus protocol interface device which are connected in sequence. The communication protocol converter is reasonable in structural design, low in cost and convenient and reliable to use.
Description
Technical field
The utility model relates to a kind of communications protocol transducer, particularly a kind of the HART protocol conversion is become the communications protocol transducer of Profibus agreement, be used for flowmeter, pressure transmitter, temperature transmitter etc. and defer to the field instrument of HART agreement and defer to exchanges data between the field control system of Profibust agreement.
Background technology
HART (Highway Addressable Remote Transducer), the open communication agreement of highway addressable remote transducer is a kind of communication protocol that is used between field intelligent instrument and the control room equipment that U.S. Rosement company released in 1985.PROFIBUS is a kind of field bus technique that is used for the monitoring of factory automation workshop level and scene equipment level data communication and control, can realize that scene equipment level arrives the digital control and on-scene communication network of distributing of workshop level monitoring, thereby for realizing that factory integrated automation and field apparatus intellectuality provide feasible solution.At present, general communications protocol transducer adopts specific PLC (Programmable Logic Controller) exploitation or customization special-purpose software gateway to carry out protocol conversion.Adopt specific PLC development technique more complicated, cost is higher; Customization special-purpose software gateway then needs to operate on the computer of appointment, is vulnerable to the influence of operating system or Computer Hardware Malfunctions, and reliability is relatively poor.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned shortcoming in the prior art, and a kind of reasonable in design, cost is low, reliability the is high communications protocol transducer that the HART protocol conversion is become the Profibus agreement are provided.
The technical scheme in the invention for solving the above technical problem is: a kind of the HART protocol conversion is become the communications protocol transducer of Profibus agreement, it is characterized in that: comprise HART protocol interface device, protocol processes one-chip computer module, process chip module and Profibus protocol interface device; Described HART protocol interface device, protocol processes one-chip computer module, process chip module, Profibus protocol interface device connect successively.
Protocol processes one-chip computer module described in the utility model comprises processing single chip, memory and No. two processing single chip No. one; Described memory is connected with No. two processing single chip with a processing single chip respectively.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design; 2, cost is low, and is easy to use and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1, the utility model comprises that HART protocol interface device 1, protocol processes one-chip computer module 2, process chip module 3 and Profibus protocol interface device 4.HART protocol interface device 1, protocol processes one-chip computer module 2, process chip module 3 are connected successively with Profibus protocol interface device 4. be provided with processing single chip 5, memory 6 and No. two processing single chip 7 in the protocol processes one-chip computer module 2 No. one, memory 6 is connected with No. two processing single chip 7 with a processing single chip 5 respectively.
During use, HART protocol interface device 1 connects the field instrument of deferring to the HART agreement, and Profibus protocol interface device 4 connects the field control system of deferring to the Profibust agreement.HART protocol interface device 1 receives the order of protocol processes one-chip computer module 2, receives the HART protocol signal, and conversion of signals is become processing single chip 5 receivable signal formats No. one.No. one processing single chip 5 is carried out computing with the data that receive, and after the computing, deposits the data after the computing in memory 6 and preserves.To exist the data of memory 6 to read the row operation of going forward side by side by No. two processing single chip 7, the form that converts Profibus to is written to process chip module 3.Profibus protocol interface device 4 receives the signal of process chip module 3 and sends the Profibus protocol signal according to the order of protocol processes one-chip computer module 2.Carry out exchanges data between Profibus protocol interface device 4 and the field control system.
Claims (2)
1. one kind becomes the communications protocol transducer of Profibus agreement with the HART protocol conversion, it is characterized in that: comprise HART protocol interface device, protocol processes one-chip computer module, process chip module and Profibus protocol interface device; Described HART protocol interface device, protocol processes one-chip computer module, process chip module, Profibus protocol interface device connect successively.
2. according to claim 1ly a kind of the HART protocol conversion is become the communications protocol transducer of Profibus agreement, it is characterized in that: described protocol processes one-chip computer module comprises processing single chip, memory and No. two processing single chip No. one; Described memory is connected with No. two processing single chip with a processing single chip respectively.
