Embodiment
Native system is made up of electric energy meter, collector, concentrator, computing machine four parts of checking meter, and the concrete standard-required of each several part is as follows:
2, data transmission channel requirement
1. the electric energy meter data transmission channel requires:
User's electric energy meter requires to adopt single-phase, the three-phase and four-line electronic electric energy meter that has the RS485 interface;
The user examines the electric energy meter requirement to adopt the three-phase and four-line electronic electric energy meter that has the RS485 interface;
Various electric energy meter 485 transmission protocols must satisfy the additional stipulations that 645 stipulations promulgated by the ministries or commissions of the Central Government and my company provide.
2. collector data transmission channel standard:
Collector up with concentrator between communicate by letter and must adopt low-voltage power line as data transmission channel, communicating by letter between descending and the electric energy meter must adopt the RS485 line as data transmission channel.
Concentrator data transmission channel standard:
Concentrator is up to adopt PSDN (talking path, city) as data transmission channel with the compunication requirement of checking meter, communicate by letter between descending and the collector must the employing low-voltage power line as data transmission channel.
System of the present invention has following advantage:
The high native system of the rate of copying guarantees that once the rate of copying reaches 95% in 500 meters radius of electricity supply scopes.Concentrator can guarantee to realize that by carrier wave on average every electric energy meter is copied 8 times every day at least.
The strong present most of carrier wave centralized meter-reading system of system's operational reliability is because the distance of checking meter is as one wishes not to the utmost, the route meter reading methods that adopt more, electric energy meter was copied equipment as commentaries on classics in the middle of both having used for the distant electric energy meter of relative concentrator, changeed by the one-level level and copied and could copy electric energy meter.In the practical application, some system uses nearly 5 grades of routes.This mode is brought two fatal problems, and the one, increased the time of checking meter greatly, the checking meter the time of 10 times of 5 grades of minimum needs of route, this still can both guarantee under the case of successful in each route; The 2nd, greatly reduce reliability of system operation, because, certainly will influence normally making a copy of of a sheet of electric energy meter once the electric energy meter that commentaries on classics is copied as route breaks down.System checks meter and all adopts directly point-to-point mode of making a copy of electric energy meter of concentrator, does not need any route relaying.Therefore system a certain intermediate link fault can not occur and causes system's affected situation of large tracts of land of checking meter, and yet fast relatively many of the speed of checking meter.
Antijamming capability is strong
Carrier wave centralized meter-reading system antijamming capability is by force to be based upon on following three bases:
1. the carrier wave data that transmit an electric energy meter comprise synchronously, verification etc., by encoding compression 5 bytes of need only.Data packet length is short more, and the degree that is interfered is just low more.
2. the system carrier frequency of operation is 15KHz, therefore has superpower signal penetration power, and the signal to noise ratio (S/N ratio) of terminal signal is improved greatly.
3. carrier wave only transmits data " 0 ", makes the content of data transmission reduce half, and disturbed probability also reduces half thereupon.
Automatically seek table function
What is called is sought table automatically, is exactly that concentrator adopts a kind of specific way of search by carrier channel, all electric energy meters under automatically platform being become fast one by one search inquiry arrive, and office is indexed in the concentrator by carrier channel with electric energy meter information such as numbering, addresses.Generally speaking, be example with 200 electric energy meters, 80% electric energy meter can be found in 30 minutes.Automatically seeking table is an important function, and it greatly reduces Installation and Debugging personnel's the workload and the debugging cycle of system, and has avoided the error of slipping up and causing because of artificial Information Monitoring.
The foundation of news file is a very loaded down with trivial details job in the carrier system debugging work, and installation personnel at first needs to add up one by one the office of all electric energy meters of installation with electric energy meter information such as numbering, address, installation sites, and manual entry is in computing machine then.After realizing looking for table function automatically, installation personnel send after finishing the installation of collector, concentrator, system can automatic office with electric energy meter preserve with electric energy meter information such as numbering, address, the table truth of a matter, and host computer gets final product by " electric energy meter data upload " order all information are imported computing machine.Can finish the work of setting up of news file after the importing middle database information, time saving and energy saving.The commissioning staff can very easily finish system debug work according to these news files.
The obstacle of realizing this function maximum is that carrier system must guarantee to have the high rate of copying.
Change table information automatic recording function
Before not having this function, after changing the table handling personnel and finishing electric energy meter and change, at first to write down the old electric energy meter table truth of a matter, will change the table work ticket then and deliver the power consuming administrative system operator according to, new electric energy meter table truth of a matter certificate.Operator's new, old electric energy meter information input power consuming administrative system of will being correlated with again carries out information translation.
After realizing this function, system's regulation when design per hour starts new table query function once automatically.After changing the table handling personnel and finishing electric energy meter and change, system can retrieve automatically in one hour at most and newly change electric energy meter, and write down old electric energy meter automatically and finally show the truth of a matter and begin to show truth of a matter certificate according to, new electric energy meter, all information stores such as automatic simultaneously table office newly numbering, address are in concentrator, when host computer is checked meter, according to user account number relevant information is imported in the host computer database automatically, need not manually carry out any typing work of changing table information system.
The realization of this function must have the height of the carrier wave rate of copying to be the basis.
Long-range arrearage notice
Most of resident's arrearages are not malice, rely on manpower to notify the resident of arrearage one by one, and finishing and calling the work of taking a lot of work as a very loaded down with trivial details thing.Do you how the automatic accurate errorless notice of arrearage information be arrived each defaulting subscriber? this is the problem that the carrier wave centralized meter-reading system need solve.System can realize long-range arrearage informing function at present.Operating personnel can be glimmered by the very convenient Long-distance Control defaulting subscriber electric energy meter arrearage pilot lamp of finishing of computing machine, and also remote controlled time of fire alarming section and time of fire alarming length free the meter reading personnel from loaded down with trivial details work.
Realize that this function carrier system not only will have the very high rate of copying, and also must have very high data transmission credibility.
Long-range notics of charge (enhanced functional I needs to increase the demonstration annex)
In the sub-district of realizing carrier meter reading system, by installing the demonstration annex additional, the menology truth of a matter in the long-range transmission, this menology truth of a matter, this month power consumption, this month should the pay dues amount of money etc. call the microform display device of charge information to each building, thereby realize long-range notics of charge.User's paying information roll display, the user is by the button fast query paying information separately of display screen.
Zero data is preserved accurately
System adopts the mode of freezing to realize what zero data was preserved.All have clock in the collector, the table truth of a matter that collector will connect electric energy meter down by 485 channels during zero point every day is saved in the internal memory (storage chip can guarantee that collector outage do not lose data in 10 years) according to making a copy of, concentrator was copied back each electric energy meter zero data one by one by carrier channel after zero point.Because system can guarantee that the minimum height of copying 8 times of every electric energy meter every day copies rate, zero data can not occur and gather and untimelyly cause the phenomenon that the date covers dislocation, and guarantee that each electric energy meter zero data makes a copy of the error of time less than 20s.Therefore be right-on as the line loss analyzing data source.
Although the present invention here specifically describes in conjunction with the specific embodiments, but be understandable that this is illustration rather than restriction, under the prerequisite of the spirit of the present invention that does not break away from accessory claim and limited, in the scope of and accompanying drawing disclosed at preamble, it all is possible reasonably changing and revising.
