Abstract
The invention discloses a self-adaptive meter reading method applied to a water-gas heat meter, which relates to the field of data information acquisition and is used for perfecting automatic meter reading of a converter.
Description
Technical Field
The invention belongs to the field of data information acquisition, and particularly relates to a self-adaptive meter reading method applied to a water-gas calorimeter.
Background
The four-meter engineering is a key engineering promoted by national grid companies in recent years, and the existing power system acquisition platform is utilized to realize a water, electricity, gas, heat and other public utility data integrated remote reading mode, so that a novel energy utilization service mode is created, the construction of a smart city is comprehensively supported, and the reading workload and the repeated construction of hardware are reduced. At present, except that electric meters have unified national standards and specifications, other water meters, heat meters and gas meters which are put into use are all produced by different manufacturers or different batches of the same manufacturer, meter protocols and communication serial ports are different, so that data acquisition of the water meters, the heat meters and the gas meters cannot be performed uniformly, and the batch refitting of the meters can bring great workload and is not paid.
Therefore, how to realize the unified reading of the multi-protocol and multi-type meters becomes a key point for technical problems to be solved urgently and for research all the time by technical personnel in the field, and the invention provides a reasonable and effective solution for the problems.
Disclosure of Invention
Aiming at the defects in the application, the invention provides a self-adaptive meter reading method applied to a water-gas heat meter aiming at a converter, which is used for solving the problem that the meters of various types and multiple protocols cannot be read uniformly at present, greatly reducing the workload of manual meter reading and effectively promoting the construction of smart cities.
In order to achieve the above object, the present invention provides a method for adaptive reading of a water-gas thermometer, comprising: according to the archive information acquired by the converter from the uplink acquisition terminal, different serial port parameters (a general protocol such as 188-channel 2004 needs to perform combination trial of serial port baud rate and verification, most factory-defined protocols have clear serial port parameters and do not need to perform serial port trial) are matched according to a meter protocol sequence supported in the converter, interaction trial is performed one by one through a protocol + serial port parameter arrangement combination mode, after interaction is successful, the protocol type and the serial port information corresponding to the meter are stored, and later communication performs corresponding meter protocol conversion and corresponding serial port issuing on an interaction command issued by the uplink acquisition terminal equipment according to self-adaptive meter reading information. When the meters are added in batches or are rotated, the converter can re-identify the protocol according to the self-adaptive flow according to the files as long as the uplink acquisition terminal issues a meter reading command corresponding to the meter files. The invention has the beneficial effects that: the electric meter centralized reading collection system compatible with the current state network can read water, gas and heat meters with different protocols through fixed format messages. The method only needs to obtain the meter address and the meter type from the uplink protocol, other parameters are not needed, and the uplink protocol is less expanded and changed on the basis of the original standard protocol. The method supports the unified reading of multi-manufacturer, multi-type and multi-protocol meters, automatically identifies the meter protocol and the serial port parameters, and does not need manual intervention. For batch new meter adding and meter replacing, the converter can perform corresponding self-adaptive processing, and the workload of later maintenance is reduced.

FIG. 2 is a flow chart of a method for adaptive meter reading of a water-gas calorimeter according to the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the converter communicates with the uplink acquisition terminal device through a carrier or Rs485 serial port, and the uplink acquisition terminal device issues a water, gas and heat meter reading command according to a standard communication message format of a power system.
As shown in fig. 2, after the converter is connected to the power information acquisition system, the master station issues the meter file under the converter to the acquisition terminal, the converter records the meter file to be read through the periodic task or the real-time task of the acquisition terminal, the adaptive meter reading is started at a random time every day (the random time is for preventing the wireless meter reading conflict), and after the meter reading is started, whether the identified protocol exists in the converter or not is judged.
If the converter does not have the identified protocol, judging whether the number of file storage days exceeds 3 days one by one according to the sequence of the meter files, if not, matching different serial port parameters (the general protocol such as 188-charge 2004 needs to carry out the combination trial of serial port baud rate and verification, most manufacturers have definite protocol serial port parameters without serial port trial) according to the protocol sequence supporting the self-adaptive meter reading in the converter, and carrying out the meter reading trial one by one through the arrangement combination mode of the protocol and the serial port parameters until the meter reading is successful or all the protocol attempts are finished. If the meter reading is successful, the converter records that the current protocol is the identified protocol, records the protocol information of the meter, tries to read all the meter files behind the meter by using the protocol, and records the protocol information corresponding to all the successful meters. And repeating the self-adaptive meter reading process from the first failed meter behind the meter file until all the failed meters are subjected to one self-adaptive reading. If the number of the file storage days exceeds 3 days, judging whether the interval between the file storage days and the last self-adaptive meter reading is 2 days, if so, executing the self-adaptive meter reading process, otherwise, ending the meter reading task on the current day.
If the identified protocol exists in the converter, respectively comparing each identified protocol with the corresponding protocol in all the meter information according to the recorded protocol sequence, and reading the meter according to the current protocol if the current protocol is consistent with the corresponding protocol in the meter information or the meter is a failed meter which is not read; and if the current protocol is inconsistent with the corresponding protocol in the meter information, performing comparison reading of the next meter until the current protocol is compared and executed with all meter information, and then performing cycle comparison of the next recording protocol. After all the identified protocols are compared, if the records have the tables which are never read and become successful, the number of days of the failed table files is judged, if the number of days is within 3 days, the reading is tried according to the self-adaptive meter reading process, and if the number of days exceeds 3 days, the task of reading the meter on the same day is ended.
For the batch new meter and the alternate meter, the file is only required to be issued to the acquisition terminal through the acquisition master station, and the converter can try to read and record the new meter file according to the self-adaptive meter reading process without other manual operation.
