Description
Technical field
The present invention relates to a kind of remote wireless data collection system, particularly a kind of method that realizes controllable timing work of data terminal unit.
Background technology
Be accompanied by GPRS (General Packet Radio Service, GPRS) fast development, GPRS DTU (Data Terminal Unit, data terminal unit) has been widely used in departments such as Automation of Electric Systems, industrial monitoring, traffic administration, meteorology, finance and security.GPRS DTU can read user data, has communication function, realizes the wireless terminal device of information exchange functions between user and data service center.
Because consider the function of real-time online, DTU is in the market keeping higher relatively level aspect the product power consumption.
At sector application, in order to reduce power consumption as much as possible, existing DTU mode of operation has following three kinds usually:
1. user data triggers and reaches the standard grade.Promptly when the user need send data, user data transferred to DTU by connecting line, and DTU is connected to DSC (data service centre, data service center) data service center after receiving data, realized data forwarding.
2. sms center is called out to trigger and is reached the standard grade.Promptly when sms center sent note or makes a phone call to call out DTU, DTU was connected to the DSC data service center, realized data forwarding.
3. online always.Be the DSC center that just is connected to after DTU powers on, can realize data forwarding at any time.
For example, Chinese invention patent application number CN200510050700.2 discloses the technical scheme of a kind of " based on the electric power remote Automatic meter reading system of GPRS network " by name, this technical scheme is to be made up of the communicating circuit between electric energy meter, terminal, main website and terminal and the main website, described terminal is core with the flush bonding processor, Add-In memory FLASH and data storage SDRAM, extend out GPRS communication module and RS485 serial communication module, module is provided with corresponding communication interface; Terminal adopts built-in Linux operating system; Described communicating circuit is made up of GPRS network and Internet network, terminal is by hanging a plurality of electric energy meters under the RS485 serial communication module, and by GPRS communication module access GPRS network, main website links to each other with the Internet network and realizes and the GPRS network communication by the Internet gateway.
By to the analysis of the whole file of above patent as can be seen, this technical scheme is not made any consideration to how to economize on electricity.
For another example, Chinese invention patent CN200510053888.6 discloses the technical scheme of a kind of " mobile data terminal and communication means thereof " by name, this technical scheme is that the measure that economize on electricity is taked is following cpu clock controlled step: if described mobile data terminal is placed in the wait state in service area or outside the service area, then will be in the busy state of described mobile data terminal set CPU operation clock signal change to the CPU operation clock signal of low velocity.
By to the analysis of the whole file of above patent as can be seen, this technical scheme only is suitable for the terminal of mobile communication, and is not suitable for the application of other special industry.
These three kinds of mode of operations have satisfied the needs of some industries to a certain extent, but in some special industries are used, require the occasion that equipment power dissipation is low as much as possible, transfer of data has certain rules in time as water meter, ammeter, environmental monitoring etc., these three kinds of mode of operations just can not satisfy.
Summary of the invention
