Description
Technical field
The utility model relates to a kind of remote wireless meter reading device, relate in particular to and be applied in the sub-district, data are successively uploaded by the multilayer wireless network, reach a kind of floor concentrator that is used for long-distance wireless meter-reading system at account center again by wired mode via cell terminal.
Background technology
Along with the development of social progress and urban construction, the residential quarter scale enlarges day by day, and water meter reads thus becomes distinct issues gradually.
Traditional pattern of checking meter is to be entered the room from house to house by the meter reading personnel to carry out the record of checking meter of water, accepts expense department then and leaves the water bill and send the user.The main deficiency of above-mentioned traditional pattern of checking meter is that 1. user and charge department are difficult to coordinate in time; 2. manual metering is not only chosen many and is wasted time and energy; 3. entering the room to the doorstep checks meter has brought the hidden danger on the safety.
Therefore people have researched and developed Automatic meter reading system.In the Automatic meter reading system of numerous different schemes, wireless communication mode is because of it need not to connect up, the easy-to-install advantage is subjected to attention especially.
As, China Patent No. is to disclose a kind of multi-user's coal gas, electricity, water meter automatic meter number recorder in the patent announcement of ZL 96202204.7, be characterized in, it installs a user data collecting unit in the turned position of each customer meter, pass through detection means, convert turn signal to electric impulse signal, pulse signals is carried out stored count, each data acquisition unit is gathered to be connected to a data centralized processing unit again; Infrared copying instrument by the control data centralized processing unit to the accumulated result of each data acquisition unit read, zero clearing; And infrared copying instrument is exported the data that read by output interface to other devices.The defective that above-mentioned automatic meter number recorder exists is that what its transmission mode adopted is that infrared mode transmits data, has the transmission range weak point owing to infrared, thereby produces the unsettled defective of data transmission.
And for example, China Patent No. is to disclose a kind of automatic meter number recorder that utilizes telephone wire in the patent announcement of ZL 02200581.1, this device comprises user side and management end, user side is made up of water meter, collector, data processor, water meter transfers data to collector, and collector and data processor transmit data by wireless mode, and the wireless transmit frequency is about 400MHz, data processor and management end transmit data by telephone wire, realize automatic data logging.This device is owing to be to utilize telephone wire to carry out automatic data logging, so wireless mode only is confined to the user side scope, requires the user must have the hardware condition of telephone wire.
Realize what the long distance data transmitted if utilize the wireless channel in space, its advantage is not only simple, convenient, and do not need existing circuit is changed, and transmission band broad, long (general tens kilometers of communication distance, also can extend to farther by relay station), especially avoid wiring to register one's residence, check meter and register one's residence, reconstruction of the old city town there is important and practical meanings.But this systems face a such problem: wireless data transmission exist buildings to effects such as the reflection of radio signal, absorptions under signal transmission problem of unstable, showing tool installation site, spatial interference etc. in addition also has considerable influence to the steady operation of data transmission, also has problems such as power consumption simultaneously.How to address the above problem well the superiority-inferiority to total system is played very big influence, because in a single day the whichever module breaks down in the system, it does not possess the function of timely reflection particular problem itself, so system just can't determine abort situation and even eliminating rapidly, this just makes total system lose self-checking function, be difficult to the operation steady in a long-term of assurance system energy, and be not easy to following maintenance.
