Abstract
The utility model relates to a wireless data acquisition device with batteries as power supply, comprising a signal sensor module, a microprocessor module, and a wireless data emission module. An electronic switch is added between the power supply modules and a battery. Controlled by the microprocessor module, the electronic switch turns on only when sending data and cuts off battery power supply at other time, which keeps the collector at a low power consumption standby status and greatly saves electric energy. The utility model realizes low power consumption standby, prolongs the working time of the collector with the batteries as power supply, enables the collector to work for more than two and a half years and meets the requirements of low power consumption of the battery power supply, thus saving the trouble of city network routing of the collector and facilitating theftproof hiding installation.
Description
Technical field
The utility model relates to a kind of data acquisition device, relates in particular to a kind of battery-powered data acquisition device.
Background technology
In prior art, some monitoring systems often need be carried out data acquisition, as hydrologic monitoring system, environmental monitoring system, national treasury guard against theft and alarm system, transformer anti-theft system, and the burglary-resisting system of high pressure, ultrahigh voltage power circuit etc.These monitorings and burglary-resisting system generally are that the data acquisition device is installed in monitoring point or antitheft some place, for monitoring, the data acquisition device carries out a data acquisition every a time interval to monitored target, and regularly the data wireless of being gathered is transmitted into the computing machine of monitoring center, by the computing machine of monitoring center data are handled.For antitheft, in a single day the data acquisition device collects anti-theft signal, then starts immediately, and anti-theft signal is wirelessly transmitted to the computing machine of Surveillance center, carries out burglar alarm by the computing machine of Surveillance center and handles.At present, the data acquisition device mostly adopts 220V city net and reserve battery power supply, and its shortcoming is all to need to lay city's net supply lines in each control point, and is cumbersome, if some places do not have city's net facility as the hydrology, environmental monitoring sites, the very trouble that just seems connects up especially for this reason.For the anti-theft wireless data acquisition unit, then be unfavorable for hidden installation with city's net power supply, supply lines is cut off easily, and collector was lost efficacy.
The utility model content
The purpose of this utility model is the shortcoming that overcomes in the prior art, and a kind of battery-powered data acquisition device of low-power consumption is provided, and makes it exempt the puzzlement of city's screen cloth line and be beneficial to theftproof hidden to install.
The electricity consumption that the utility model has been analyzed the data acquisition device distributes, and what the result showed the power consumption maximum is the wireless data transmission module, and it just just works when data transmission, and when not launching, it can not worked.Therefore, the utility model has adopted a kind of method of Based Intelligent Control power switch, allows the wireless data transmission module just just power when the emission data, and is not its power supply during data acquisition at ordinary times.Like this, just can reduce the collector power consumption greatly.
The concrete technical scheme of the utility model is as follows:
It comprises signal transducer module, microprocessor module and wireless data transmission module, it is characterized in that: the feeder ear of described signal transducer module, microprocessor module and wireless data transmission module joins by an electronic switch and a battery, an output port of the control end of described electronic switch and microprocessor module joins, and is provided with an energy-saving control module that is used to control electronic switch in the described microprocessor module.
The further improved technical scheme of the utility model is as follows:
Described battery is a lithium battery.
Described electronic switch is a fet switch.
The utility model has reached low-power consumption standby, prolonged the working time of data acquisition device under powered battery greatly, but make the collector continuous working more than two and half, satisfied battery powered low-power consumption requirement, install thereby remove the puzzlement of collector wiring from and be beneficial to theftproof hidden.Moreover the utility model can also further prolong the working time of collector by selecting the means of high electric weight lithium battery and low power dissipation electron switch for use.
Description of drawings
Accompanying drawing, circuit theory diagrams of the present utility model.
Embodiment
Referring to accompanying drawing, this data acquisition device comprises signal transducer module 1, microprocessor module 2, wireless data transmission module 3, described signal transducer module 1 is mainly flated pass by various monitoring sensors and sensor electrical and is changed circuit and constitute, and this module is exported the signal voltage of one or more 0～5V or the signal input interface P0 that microprocessor module 2 is sent in pulse; Microprocessor module 2 can adopt existing single-chip microcomputer integrated device, and be preferably with A/D converter, if 1 output of signal transducer module is simulating signal, then microprocessor module 2 is converted into digital signal earlier, and then input single-chip microcomputer, the signal of single-chip microcomputer acquired signal sensor assembly 1 input at any time, and again the data of being gathered are beaten packet, then by its serial data interface RXD, TXD delivers to wireless data transmission module 3, it is the GPRS module that described wireless data transmission module 3 can adopt existing mobile module, and it arrives data transmission the computing machine of appointment under the control of microprocessor module 2.
The feeder ear of described signal transducer module 1, microprocessor module 2 and wireless data transmission module 3 joins by an electronic switch 4 and a battery 5, and a data output port WR of the control end of described electronic switch 4 and microprocessor module 2 joins.Described microprocessor module 2 has the internal cell of oneself, and it can keep a low-power consumption standby state of microprocessor after disconnecting power supply, thus some necessary datas of preserving processor.Not during acquired signal, microprocessor module 2 is in dormant state at collector, i.e. the holding state of low consumption, and during acquired signal, microprocessor module Be Controlled program is waken up, or is waken up by anti-theft signal, carries out data acquisition and packing data then and handles; When needs emissions data, microprocessor is at first controlled electronic switch 4 conductings, makes battery 5 be the collector power supply, and then controls wireless data transmission module 3 data transmission is gone out.After emission is finished, control electronic switch 4 again and end, cut off battery 5, thereby reach purpose of saving.Described battery preferably adopts the lithium battery of high electric weight.Described electronic switch preferably adopts fet switch, because the Control current of this switch when conducting is very little, meets the low power consumption control requirement, and power consumption is further reduced.
