The automatic meter data coping system has simple structure, low cost, low power consumption and uneasy generation of electromagnetic interference.
Description
Technical field
The utility model relates to the Automatic meter reading system of water meter, ammeter, gas meter and hotlist etc.
Background technology
Automatic meter reading system is a kind of intellectualized management system, and it does not need the copy reading personnel to reach the spot, and just can finish the data that the user is consumed water meter, ammeter, gas meter, hotlist etc. and carry out copy reading.It can be sent to the data of measuring apparatus such as a plurality of water, electricity, gas, heat on the concentrator of sub-district by specific communication modes, by remote communication modes the data that received are sent to collection again and copy on the long-range master station computing machine at center.
The Automatic meter reading system of prior art is that the GPRS wireless network terminal is installed on measuring apparatus, the server networking that utilizes the covering of existing GPRS wireless network and the GPRS modulator-demodular unit is housed reaches the purpose of remote automatic meter reading, though this mode has reduced the construction period of engineering, but because the existing needed measuring apparatus of family (as water meter, ammeter, gas meter, hotlist etc.) is many, if each measuring apparatus is all installed the GPRS wireless network terminal, then increase the cost of Automatic meter reading system greatly, caused it to be difficult to large-area application.
As to above improvement, the China national intellecture property has been announced a kind of Automatic meter reading system based on the ZigBee technology on the net, it is made of measuring apparatus, collector and concentrator, measuring apparatus is carried out exchanges data by bus and collector, collector is sent to the concentrator that ZigBee technology wireless communication module and GPRS communication module are installed by ZigBee technology wireless communication module with data then, and last concentrator is sent to collection with these data by the GPRS communication module and copies on the long-range main control computer at center.Though this mode has reduced cost to a certain extent, certain application is arranged, this Automatic meter reading system based on the ZigBee technology still has following shortcoming:
1,, thereby caused its structure more complicated because the ZigBee technology uses is direct sequence spread spectrum (DSSS) mode of IEEE802.15.4 standard.
2, because the ZigBee technology also needs to install FFD and two kinds of equipment of RFD, therefore increased cost, also increased the power consumption of equipment simultaneously.
3, since the ZigBee technical work at the frequency band of 2.4GHz, and mobile phone, micro-wave oven etc. all are operated in this frequency band, therefore are easy to produce electromagnetic interference (EMI).
Equally, because therefore above several shortcomings that the ZigBee technology exists have caused adopting structure more complicated, cost height, the power consumption height of the Automatic meter reading system of ZigBee technology and have easily produced electromagnetic interference (EMI).
The utility model content
The technical problems to be solved in the utility model is, provide a kind of simple in structure, cost is low, low in energy consumption, the Automatic meter reading system that is difficult for producing electromagnetic interference (EMI).
The technical solution of the utility model is, a kind of Automatic meter reading system with following structure is provided, and it comprises at least one measuring apparatus, at least one collector and concentrator; Be equipped with the Z-Wave wireless communication module on described collector, the concentrator, described collector input end is connected with described measuring apparatus, and its output terminal is connected with described concentrator.
After adopting above structure, the utility model Automatic meter reading system compared with prior art has following advantage:
1, because the Z-Wave technology uses is frequency modulating (FSK) wireless communication mode in the industry, therefore, it is relatively simple for structure.
2,, therefore reduced cost relatively, simultaneously because the minimizing of equipment has also reduced power consumption because the Z-Wave technology is not installed FFD and two kinds of equipment of RFD.
3, because the ISM frequency band of the 900MHz of Z-Wave technical work, and the equipment of working on this frequency band is less, therefore is not easy to produce electromagnetic interference (EMI).
Same because above several advantages that the Z-Wave technology exists, so, adopt the Z-Wave technology Automatic meter reading system relatively simple for structure, cost is low, low in energy consumption and difficult generation electromagnetic interference (EMI).
Description of drawings
The structural representation of Fig. 1 the utility model Automatic meter reading system.
Fig. 2 is the inner structure synoptic diagram of the utility model collector.
Fig. 3 is the inner structure synoptic diagram of the utility model concentrator.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model Automatic meter reading system, it comprises a plurality of measuring apparatus, a plurality of collector and concentrator; Described collector, concentrator are equipped with the Z-Wave wireless communication module, and the collector input end is connected with a plurality of measuring apparatus, and its output terminal is connected with concentrator, and the input end of concentrator is connected with a plurality of collectors; Wherein, measuring apparatus is ammeter, water meter, gas meter or hotlist.
As shown in Figure 2, collector comprises CPU (central processing unit), data-carrier store, Z-Wave communication module, other outer perisotomice and power circuit, and CPU is connected with data-carrier store, Z-Wave communication module, other outer perisotomice, power circuit respectively.
As shown in Figure 3, concentrator comprises CPU, Z-Wave communication module, power circuit, 8251A, clock circuit, watchdog circuit and GPRS communication module, and CPU is connected with Z-Wave communication module, power circuit, 8251A, clock circuit, watchdog circuit, GPRS communication module respectively.
Being connected of collector and concentrator then is by go forward side by side line data exchange of the wireless connections of Z-Wave communication module.Concentrator and collection are copied the communication of the Remote Computer Center at center and are carried out data transmission by GPRS or CDMA.
The management software of long-range main control computer sends to concentrator in the Automatic meter reading system network of Z-Wave technology by telecommunication means (as GPRS, the CDMA etc.) order of will checking meter, again by order being sent to each collector by broadcast mode, each collector is with these novel data-carrier stores (as EEPROM) that deposits in, when concentrator when collector is given an order, each instruction has the address of collector and measuring apparatus.After collector receives instruction, must be identical just the replying of device number, otherwise not reply.If concentrator is confiscated response in a period of time, then report an error.After each measuring apparatus receives signal, data are sent to relative collector, collector is sent to concentrator with these data by the Z-Wave network again, and concentrator then is sent to collection by telecommunication means (as GPRS module, CDMA module etc.) and copies on the long-range main control computer at center.
