Description
One, technical field:
The present invention relates to a kind of Automatic meter reading system, particularly disclose the method for the quantitative timed sending continuous data of a kind of wireless meter reading system terminal.
Two, background technology:
Civilian intelligence table such as at present domestic water meter, gas meter, flow meter, calorimeter meter mostly is the IC-card table greatly, relative merits this paper of table such as IC-card water meter, gas meter, flow meter, calorimeter meter does not comment in detail, only is illustrated at domestic wireless table tool (terminal herein all refers to wireless table tool).At present the transmission mode of the wireless table tool of the wireless kilowatt meter reading-out system that occurs is all based on the interrogation reply system of two-way communication, promptly a two-way micropower wireless data transmission module is installed at table tool end, concentrator regularly sends request msg to table tool terminal, when table tool end is received the data of concentrator transmission, continuous data with table tool end, tamper, anti-cutting, meter reading datas such as magnetic perturbation send to concentrator, concentrator is transferred to computer administration center by carriers such as write by hand devices again, there are several shortcomings in such system: 1, the system cost height, because adopt two-way micropower digital transmission module as wireless communication transmissions, causing to have radiating portion that the receiving unit circuit is arranged again in the system, thereby has increased system cost.2, average for consumption greater than 100uA, system power dissipation is big, thus can not dormancy because system adopts the two-way communication system usually to be in accepting state, so system power dissipation is very big, be not suitable for very much the powered battery occasion.3, communication reliability is poor; because often will sending instruction to terminal (table meter), concentrator cause amount of communication data very big; usually can make communication data usually disturbed because of there being a lot of data communicating the co-channel interference that causes radio communication in the air, can not proper communication.Also there is not a kind of mode preferably to solve this situation at present.
Three, summary of the invention:
The objective of the invention is to resolve the problem of communicating by letter and existing between the terminal and concentrator in the prior art wireless kilowatt meter reading-out system, the wireless kilowatt meter reading-out system of water, gas, hotlist tool is work well.
The present invention is achieved in that the method for the quantitative timed sending continuous data of a kind of wireless meter reading system terminal, and the battery-powered wireless signalling generator of automatic data logging, concentrator, write by hand device, the administrative center of wireless long-distance meter-reading system forms, and it is characterized in that:
A) the wireless signalling generator of automatic data logging adopts powered battery, satisfies 10uA low-power consumption requirement 8 years tenure of use, and the open ground communication distance is greater than 600 meters;
B) set a minimum quantity forwarded and the minimum interval time that sends and table tool numbering in the wireless signalling generator of automatic data logging;
C) tool pulse of the wireless signalling generator acquisition tables of automatic data logging or direct-reading data automatic gauge are checked power supply, tamper simultaneously, are anti-ly cut, magnetic perturbation table tool data;
D) when user's water, when power consumption equals minimum quantity forwarded, the wireless signalling generator of automatic data logging promptly can be with continuous data and electric quantity of power supply, tamper, anti-ly cut, the magnetic perturbation data wireless sends in the concentrator, if in minimum transmission time interval, do not satisfy the condition of minimum quantity forwarded, then satisfy Desired Min Tx Interval during the time, the wireless signalling generator of automatic data logging also can be automatically with the continuous data of internal memory and current electric quantity of power supply, tamper, anti-ly cut, the magnetic perturbation data wireless sends in the concentrator;
E) write by hand device data that the wireless signalling generator of the automatic data logging in the concentrator is transmitted are copied and are got in the write by hand device, then with in all data importing administrative center computer systems.
The wireless signalling generator of described automatic data logging, it is interconnected to a system by single-chip microcomputer, wireless telecommunications chip, wireless communication signals processing, power supply, the pulse signal that single-chip microcomputer is used for directly gathering water meter, gas meter, flow meter remote installed meter tool carries out automatic gauge, single-chip microcomputer passes through the interrupt mode pulse signal of monitoring form tool constantly simultaneously, prevent taking out stitches, preventing trimming, and the remote installed meter tool is subjected to the signal of rogue attacks; Whether the single-chip microcomputer also electric weight of time monitoring power supply can keep system works, if electric quantity of power supply is lower than the minimum amount of power of default, single-chip microcomputer will produce warning and by wireless telecommunications chip and wireless communication signals treatment circuit alerting signal be launched; Wireless telecommunications chip and wireless communication signals treatment circuit are mainly used in the various data of system are carried out wireless transmission.Single-chip microcomputer is selected 8 single-chip microcomputers of Atmel Corporation for use in the system, and described wireless communication signals treatment circuit is selected high-performance, high-gain radio communication ∏ type filtering circuit for use.
Concentrator and write by hand device are present technical products in the system, this place is not described further, the write by hand device patent No.: CN200410024413.X, the concentrator patent No.: CN00222265.5, the automatic data logging signalling generator of wireless remote transmission acquisition terminal has been applied for utility model patent, application number: 200520047929.6.
Power supply in the system adopts lithium battery work, and the power consumption average current is less than 20uA, and powered battery tenure of use is 6～8 years, and emissive power is 10mW, and the open ground communication distance is greater than 600 meters.With reference to the accompanying drawings 1, as can be seen the table meter continuous data of terminal collection, tamper, anti-ly cut, table counting certificates such as magnetic perturbation, battery electric quantity send the data to concentrator by wireless signal, concentrator passes to computer administration center again.At present, the signal of domestic table meter output all is pulse signal basically, in order to save cost, the present invention unites two into one collection, the wireless transmit hardware of terminal, terminal both the acquisition tables tool pulse signal, tamper, anti-ly cut, data circuit such as magnetic perturbation, battery electric quantity, have radio communication circuit again.In being connected of pulse meter tool and terminal, the table tool is a double dry-reed pipe dipulse output table tool.Wireless meter reading system terminal comes the reading of gauge table by the umber of pulse of acquisition pulse table tool, gathers tamper simultaneously, anti-ly cuts, data such as magnetic perturbation, battery electric quantity.
Therefore, the present invention has the following advantages: the randomness of utilizing user's consumption within the specific limits to arrive minimum quantity forwarded greatly reduces the co-channel interference in the wireless communication procedure, has reduced system power dissipation, has significantly reduced hand labor, reduce managerial cost, improved automaticity.
