Abstract
The invention discloses intelligent meter reading system equipment and a communication rate adaptation method for a meter module, relates to intelligent meter reading system equipment, a meter module and an integrated meter consisting of the meter module, and in particular relates to middle routing system equipment (such as an isolator, an isolation relay, a note router, an acquirer, a node and a network node) of an intelligent meter reading system, a meter module (such as a water meter module, an electric meter module and a gas meter module) and an integrated meter (such as a water meter, an electric meter and a gas meter). According to the communication rate adaptation method, the communication rate and a protocol are automatically identified and processed by identifying characteristic bytes of a data frame header; the communication rate of 1,200 bps or 2,400 bps of a data frame sent by superior equipment or a computer can be automatically identified; a protocol 645 under 1,200 bps, a protocol 188 under 2,400 bps and other protocols customized by users under 1,200 bps or 2,400 bps can be automatically identified and processed without extra configuration; and after the automatic identification and processing of the communication rate and the communication protocol are finished, the communication rate and the protocol can automatically skip to a default state, and next data receiving can be processed.
Description
Technical field the present invention relates to intelligent meter data recording system equipment and table module and by the whole table of table module assembling, particularly middle the route system equipment of intelligent meter data recording system (isolator, isolate repeater, node router, collector, node, network node etc.), table module (water meter module, ammeter module, gas meter module), whole show (water meter, ammeter, gas meter).
Background technology intelligent meter data recording system equipment and table module and the whole table of being assembled by the table module may use different communication speeds and different communications protocol.At present industry generally adopts 645 agreements under the 1200bps communication speed and other agreements of User Defined under 188 agreements under the 2400bps communication speed and 1200bps or the 2400bps communication speed.The table module product that though the market appearance is overlapped two even more cover communications protocol integrate, but need communication speed when dispatching from the factory be set to 1200bps or 2400bps one of them, do not occur as yet identifying the product that communication speed is 1200bps or 2400bps automatically, therefore form different manufacturers is produced in the industrial chain system equipment and table module on compatibility than turbulence, also increased producer's stock difficulty.
Summary of the invention the objective of the invention is to design a kind of automatic adaptation, realizes simply being used for intelligent meter data recording system equipment and showing the communication speed adaptive approach that module reaches the whole table of being assembled by the table module, thereby has also realized the self-adaptation of communications protocol by the self-adaptation of communication speed.
The present invention is that the technical scheme that adopts that achieves the above object is: design a kind of for intelligent meter data recording system equipment and table module and by the communication speed adaptive approach of the whole table of table module assembling, communication speed and agreement are identified and handled to attribute byte by the recognition data frame head automatically, the communication speed that can identify the Frame that higher level equipment or computer send automatically is 1200bps or 2400bps, can not dispose automatic identification and the protocol processes that can realize under the 1200bps other custom protocols of user under 188 agreements under 645 agreements and 2400bps and 1200bps or the 2400bps in addition; Automatically after identification and processing communication speed and agreement finished, automatically with communication speed and agreement rebound default conditions, handling next time, data received.
The present invention identifies and handles communication speed and agreement automatically by the attribute byte of recognition data frame head, can realize the highly compatible of communication speed and communications protocol and integrated, simplified design, system equipment and the table module of being convenient to different manufacturers are exchanged, and reduce the stock kind, simplify the Default Value formality, reduce producer's stock cost.
Embodiment is following, and the invention will be further described.
A kind of for intelligent meter data recording system equipment and table module and by the communication speed adaptive approach of the whole table of table module assembling, communication speed and agreement are identified and handled to attribute byte by the recognition data frame head automatically, the communication speed that can identify the Frame that higher level equipment or computer send automatically is 1200bps or 2400bps, can not dispose automatic identification and the protocol processes that can realize under the 1200bps other custom protocols of user under 188 agreements under 645 agreements and 2400bps and 1200bps or the 2400bps in addition; Automatically after identification and processing communication speed and agreement finished, automatically with communication speed and agreement rebound default conditions, handling next time, data received.
Because 645 communications protocol and 688 communications protocol have typical data frame format, if the User Defined agreement also has the data frame format of similar or reference, by analyzing different communications protocol, the Frame format change situation of data frame head especially under the different communication speeds, and by system equipment and the table module MCU carry out Intelligent Recognition, just can reach communication speed adapts under 1200bps and two kinds of communication speeds of 2400bps and adjustment automatically automatically, the whole table that system equipment and table module are reached by the assembling of table module can not need under the situation of configuration in addition, the product that both can be used as the 1200bps communication speed uses, the product that also can be used as the 2400bps communication speed uses, indirectly, the product that both can be used as 645 agreements uses, and the product that also can be used as 188 agreements uses, also may use as the product of user-defined other agreements.Multiple communication speed and multiple kinds are integrated, and do not need other configuration, this can simplify the production formality, avoids configuration error, more is conducive to producer's stock and delivery.
