Description
Technical field the present invention relates to the method and apparatus of control system, especially the method and system equipment of the wireless centralized control system of gate inhibition/door lock.
Background technology gate inhibition is meant the closing device of opening of courtyard gate, regional centralized passage, and door lock is meant the lock of single house unit.Prior art is a lot of to quantity, can form the gate inhibition/door lock of system, and the method and system equipment that adopts when carrying out centralized Control all is wired mode.Though Chinese patent application CN 1337519A (application number: 01123228.5) disclose a kind of technical scheme that is called " remote-controllable door lock assembly ", can realize controlled in wireless, but its scheme does not relate to the networked wireless concentrated controling management to numerous gate inhibition/door locks in the zone to single door lock.Another part Chinese patent application CN 1335448A (application number: 00121484.5) disclose a kind of technical scheme that is called " communication remote control and the door lock assembly of warning ", the design of wireless remote control door lock has also been proposed, but its main contents are still the controlled in wireless of single door lock, and its scheme does not relate to the wireless concentrated remote control of networking yet.As everyone knows, the wireless remote control of individual equipment can't be compared on the technical sophistication degree with the wireless centralized Control of networking.Above-mentioned two patent applications are not because of proposing numerous gate inhibition/door locks concrete measure of control respectively how in same wireless network, so its scheme realizes all that apart from solving all gate inhibition/door locks of zone wireless on-line file chemical control system also has very big distance.
The summary of the invention the problem to be solved in the present invention is to avoid above-mentioned the deficiencies in the prior art part and the method and system equipment that proposes a kind of wireless centralized Control gate inhibition/door lock (terminal).Native system physically is made of main website, repeater and gate inhibition/door lock (terminal), and the division of Qu Qun and sub-district is arranged again in logic.The sub-district is meant the communications zone that a repeater and the wireless gate inhibition/door lock that links to each other (terminal) are with it formed, and the district group is meant the communications zone of forming by certain several regularly arranged sub-districts again.Native system comprises at least one district group, and each district group comprises that again at least one sub-district, each sub-district comprise 256 gate inhibition/door locks (terminal) at most.The present invention's ID number by terminal is set, distribute radio channel resource, determine frame structure, in frame information, determine the Code And Decode form, synchronous protocol is set, adopts power-saving control mode of operation, regulation communication, login step serial of methods to realize networked wireless centralized Control.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme of taking:
Construct a wireless centralized control system and comprise step:
A., it is main website that microcomputer is set, and management software and bitcom are set in main website, and main website carries out wired serial by serial line interface with a MODEM (modem) and communicates by letter.
B.MODEM (modem) communicates by letter with each repeater.
C. repeater is communicated by letter with each terminal (gate inhibition/door lock).
D. gate inhibition/door lock is accepted the instruction opening and closing door lock that main website sends, or holds contactless IC card by the user and open gate inhibition/door lock, and in real time the state of lock itself is returned main website and carry out information management by main website.
Especially:
Wireless mode is adopted in the communication of the communication of described MODEM and each repeater and repeater and each terminal (gate inhibition/door lock), forms a networked wireless centralized control system; Described step also comprises:
E. wireless centralized control system adopts 433MHz and 868MHz frequency range.
F. described wireless centralized control system comprises at least one district group; Described district group comprises at least one sub-district; Described sub-district is by maximum 256 gate inhibitions of repeater wireless connections, and each gate inhibition has ID number (address) of oneself, comprises network system number (2Byte), district group number (1Byte), cell id (1Byte) and district interior number (1Byte) for gate inhibition's ID number.
G. in wireless centralized control system of the present invention, the base unit of information transmission is a superframe, maximum information unit is a Hyperframe, a Hyperframe comprises and is no less than 4 superframes, a superframe comprises some handshake logic channels and some service logical channels, superframe is divided into common superframe and lengthening superframe, the transmission (can finish) that common superframe is used for the less order of byte number and replys according to actual conditions again in a superframe; The transmission that the lengthening superframe is used for the more order of byte number or replys.
H. each gate inhibition/door lock is uploaded information for instant application, reaches the standard grade immediately, and information uploading uses 2～4 superframes to finish.
I. information adopts CRC (cyclic redundancy) verification in transmission course, and all the transmission byte+ID of manufacturer bytes are all carried out the CRC-16 computing except that sync byte and superframe sequence number byte; If the result is consistent with the 2Byte check code of receiving, show that then the information of receiving is correct, otherwise mistake.If decoding error all in two channels (MCHA and MCHB) then requires the other side to retransmit.As long as decoding is correct in a channel (any of MCHA and two physical channels of MCHB), think that all this superframe communication is correct.
