Description

A kind of radio ammeter data collecting system and its acquisition method
Technical field
The invention belongs to ammeter data acquisition system technical field, and in particular to a kind of radio ammeter data collecting system and Its acquisition method.
Background technology
Current China builds strong intelligent grid energetically, and it is the important of strong intelligent grid that wherein intelligent electric meter collection, which is copied, Part.Existing intelligent meter data recording mode is mainly wired and wireless two kinds, and wired mode needs rewiring, cost compared with Height, it is unsuitable in some occasions, particularly rural area;Wireless mode is based primarily upon GPRS or wireless sensor network Technology to electric supply meter, it is necessary to reequip, and corresponding GPRS module of increase etc. realizes adopting respectively to each electric supply meter data Collection, cost is higher and is difficult to promote;McWiLL (Multi-carrier Wireless information Local Loop) skill Art is the broadband wireless communication technique of China's independent research, and electric power wireless private network can be set up using it, power communication is realized The covering in face, applied to ammeter data collection.
The content of the invention
It is an object of the invention to provide a kind of radio ammeter data collecting system and its acquisition method, it is not necessary to which repacking is originally Electric supply meter, realize ammeter data and automatically gather, improve operating efficiency and reliability, save human resources.
To achieve the above object, present invention employs following technical scheme:
A kind of radio ammeter data collecting system, including ammeter data collector and ammeter data transmitter, the ammeter Data acquisition unit includes processor and the Mc WiLL communication modules, the second WiFi module, the memory module that are connected with processor, institute Stating ammeter sending module includes low-power scm and the first WiFi module, the ammeter data mould that are connected with low-power scm Block.
Further, the ammeter data collector also includes the display module being connected with low-power scm and the second electricity Source module.
Further, the ammeter data transmitter also includes the first power module for being used to power to it.
A kind of acquisition method of radio ammeter data collecting system, comprises the following steps:
(1) ammeter data collector is set up with ammeter data transmitter by password authentification and is connected;
(2) ammeter data collector sends inquiry request to ammeter data conveyer, and sets timer;
(3) ammeter data conveyer sends ammeter data, Customs Assigned Number in the form of packet to ammeter data collector And password for inquiry;
(4) ammeter data collector receives the ammeter data, and carries out password for inquiry checking, if ammeter data collector Received within the time as defined in timer after the packet of ammeter data transmitter, and the success of revene lookup password, then storage is used Family encode and ammeter data, and the subscriber-coded and ammeter data of storage is shown;If revene lookup password is unsuccessful Or during timer expiry, then circulate to ammeter data transmitter and send inquiry request, sent if circulating to ammeter data transmitter Cycle-index exceed preset value when, then ignore to ammeter data generator send inquiry request.
In such scheme, in step (1), the ammeter data collector is built by password authentification with ammeter data collector Vertical connection, specifically includes following steps:
(11) ammeter data collector is according to ammeter position table, according to ammeter data transmitter Customs Assigned Number order successively Call request and calling password are sent to the ammeter data transmitter of current location, and timer is set;
(12) ammeter data transmitter receives the call request and calling password, and calling password is verified, if Call after password authentification success, then ammeter data transmitter is transferred to working condition from resting state, and to ammeter data collector Send Customs Assigned Number and user cipher;Otherwise, ammeter data transmitter continues to be transferred to resting state;
(13) ammeter data collector receives the Customs Assigned Number and user cipher, and user cipher is verified, if After user cipher is proved to be successful, then next step is carried out, otherwise, return to step (11) carries out circulate operation, if cycle-index exceeds During preset value, then ignore to current ammeter data generator and send inquiry request, call next ammeter data transmitter.
In such scheme, in the step (12), the ammeter data transmitter is transferred to resting state, including following step Suddenly:
(121) ammeter data collector sends dormancy instruction and dormancy password to ammeter data transmitter;
(122) ammeter data transmitter receives dormancy instruction, and verifies dormancy password, turns after dormancy password authentification success Enter resting state.
In such scheme, the Customs Assigned Number uses six bytes, in the range of 1~248, full 0 and complete 1 without using.
It is further comprising the steps of after step (4) in such scheme:
(5) after ammeter data collector reaches the region of the McWiLL network coverages, all user profile of storage are led to Cross McWiLL networks and be sent to remote platform.
As shown from the above technical solution, radio ammeter data collecting system of the present invention and its acquisition method, electricity consumption Information transfer rate is fast, accuracy is high, real-time is good, and meter reading process is full-automatic, it is ensured that manpower money is saved while reliability Source.The present invention need not reequip original electric supply meter, be mounted directly, it is easy to promote, and poll is used according to ammeter position table Mode communicates, and solves multiple ammeter data transmitters in the same period and sends data to an ammeter data collector, has Cause the problem of data receiver malfunctions there may be conflict.Unique user is distributed by this method to ammeter data transmitter to compile Number and user cipher, can prevent illegal ammeter data transmitter from accessing;Simultaneously using call instruction and calling password, inquiry Instruction and password for inquiry, dormancy instruction and dormancy password, can prevent illegal calling to ammeter data transmitter, inquiry and Sleep operation.
