A data collector comprises a main control unit, a communication module, an AD conversion module, a power supply module, an output control module, a memory module, a wireless transmission module and a display module. The data collector has collection, data storage and transmission functions; the instrument precision is effectively improved; the circuit design is optimized; and the energy consumption of the data collector during outdoor wireless communication is reduced.
Description
Technical field
The utility model relates to the improvement technology of data collecting instrument.
Background technology
Along with the development of scientific experiment and Industry Control to increasingly automated and microelectric technique; For data acquisition system (DAS) provides the good technical basis, also more important for the collection of data in various scientific experiments and the Industry Control, existing data collecting instrument function imperfection; Energy consumption is big; Precision is low, and operation is visual poor, limited use system.
The utility model content
In view of this, the utility model technical matters that will solve provides a kind of centralized procurement collection, stores, is transmitted in the High Precision Digital Acquisition of one.
In order to solve the problems of the technologies described above, this technical matters adopts following scheme to solve:
A kind of data collecting instrument comprises main control unit and is connected on the main control unit and through main control unit control:
Be used for communication module that 485 signals and TTL signal are changed,
Be used for 4-20Ma signal transition with outside input and be the AD modular converter that main control unit can identification signal,
Be used for providing the power module of power supply to main control unit,
Be used to respond the output control module of the opening/closing power supply instruction that main control unit sends,
Be used to store the memory module of data,
The wireless transport module of transmission data, through GSM network or cdma network or GPRS network or 3G network communication,
Be convenient to realize that man-machine interaction shows the display module of each item information.
Wherein, described AD modular converter is 16 modules.
The utlity model has collection, data storage and transfer function, effectively improved accuracy of instrument, optimized circuit design, reduced the energy consumption during Acquisition Instrument wireless telecommunications are in the open air used.
Description of drawings
Fig. 1 is the utility model embodiment topology synoptic diagram.
Embodiment
Below will combine accompanying drawing and embodiment that the utility model is described in further detail for the ease of it will be appreciated by those skilled in the art that:
The data collecting instrument that present embodiment discloses adopts the body structure of sealing, makes it applicable to rugged surroundings such as fields.This data collecting instrument comprises main control unit 1, communication module 2, AD modular converter 3, power module 4, output control module 5, memory module 6, wireless transport module 7 and display module 8.
Wherein, main control unit 1 is the core component of data collecting instrument, is accomplished by main control unit 1 for control, communication module 2 signal judgment and response and the reading all of AD modular converter signal of output.Main control unit 1 is in dormant state when flat, in case receive that the signal of communication module 2 is promptly waken up at once, and in 5 outputs of setting-up time inner control output control module, read the AD signal, handle the signal of communication module 2.
Communication module 2 is 485 communication modules, is made up of RS485 conversion of signals IC and peripheral passive device, and major function is the conversion of carrying out between 485 signals and the TTL signal.
Output control module 5 is made up of two power source conversion modules and peripheral components, and major function is the instruction of the opening/closing power module 4 that sends of response main control unit 1.
Power module 4 is used for to main control unit power supply being provided, and has the protection of power supply reversal connection, is responsible for main control unit 1 stable power is provided, and externally export the 5V power supply.Each chip assembly all adopts the outstanding low quiescent current LDO of renowned company, for current drain extremely low under the holding state is laid a good foundation.This controller standby mode power consumption reaches a milliampere level.
It is that main control unit can identified signal that AD modular converter 3 is used for 4-20Ma signal transition with outside input, gathers so that main control unit 1 carries out AD, and this AD modular converter is 16 modules, has effectively improved accuracy of instrument.
Memory module 6 is used to store data, and can realize the data scrolling storage.
Wireless transport module 7 is used to transmit data, can support GSM network or cdma network or GPRS network or 3G network communication mode.
Display module 8 is used to realize man-machine interaction, is convenient to as required instrument working environment etc. carried out programming Control, can show each item information.
More than be the wherein concrete implementation of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these conspicuous replacement forms all belong to the protection domain of the utility model.
