Long-distance intelligent multidata collector
Technical field
The utility model relates to the data acquisition unit field, is specially a kind of long-distance intelligent multidata collector.
Background technology
In modern sensor monitoring field, often need to use a plurality of sensors and cooperatively interact and carry out multi-parameter monitoring.For the data that a plurality of sensor acquisition arrive, need the corresponding data acquisition device to gather.The data acquisition unit processing power of prior art is relatively poor, and a plurality of data-handling efficiencies that arrive for a plurality of sensor acquisition are lower, and can't realize real-time control to the data collector.
The utility model content
The purpose of this utility model provides a kind of long-distance intelligent multidata collector, and is poor with the data acquisition unit data-handling capacity that solves prior art, the problem that can't control in real time.
In order to achieve the above object, the technical scheme that the utility model adopted is:
Long-distance intelligent multidata collector, include mainboard, it is characterized in that: be integrated with control module on the described mainboard, data processing module, the data acquisition identification module, the multiple signals modulate circuit, input/output module, described input/output module is made of the wireless transmission communication interface of wire transmission communication interface and band antenna, described multiple signals modulate circuit inserts the data acquisition identification module respectively, between described data acquisition identification module and the data processing module, be connected by data bus is two-way respectively between data processing module and the input/output module, described control module by control bus respectively with described data processing module, the data acquisition identification module, the two-way connection of input/output module.
Described long-distance intelligent multidata collector is characterized in that: described signal conditioning circuit comprises amplifying circuit, filtering circuit, removes interfered circuit and A/D convertor circuit.
Described long-distance intelligent multidata collector is characterized in that: described control module is arm processor S3C2410.
Described long-distance intelligent multidata collector is characterized in that: described data processing module is the CC2420 processor.
Described long-distance intelligent multidata collector is characterized in that: described data acquisition identification module is the AT89C52 single-chip microcomputer.
The utility model is simple in structure, be easy to realize, the arm processor S3C2410 that adopt that processing power is powerful, power consumption and cost is all lower is as control module, data processing module adopts the CC2420 processor, the data acquisition identification module adopts the AT89C52 single-chip microcomputer, by the wired of input/output module and wireless communication interface output data and input instruction.The utility model has improved the multidata processing power of data acquisition unit for multisensor greatly, and can control sensor data acquisition in real time by control module.

Embodiment
As shown in Figure 1.Long-distance intelligent multidata collector, include mainboard, be integrated with control module, data processing module, data acquisition identification module, multiple signals modulate circuit, input/output module on the mainboard, also be integrated with power management module on the mainboard, control module is arm processor S3C2410, data processing module is the CC2420 processor, and the data acquisition identification module is the AT89C52 single-chip microcomputer, and signal conditioning circuit comprises amplifying circuit, filtering circuit, removes interfered circuit and A/D convertor circuit.Input/output module is made of the wireless transmission communication interface of wire transmission communication interface and band antenna, the multiple signals modulate circuit inserts the data acquisition identification module respectively, between data acquisition identification module and the data processing module, be connected by data bus is two-way respectively between data processing module and the input/output module, control module by control bus respectively with data processing module, data acquisition identification module, input/output module is two-way is connected.
The logical process flow process of the utility model data is as follows:
Upstream data: mainly be business and status data.Each sensor is gathered the different characteristic parameter in the environmental information respectively, the information decibel is delivered to that separately signal conditioning circuit amplifies, filtering, goes to disturb and the AD conversion, and the information after will nursing one's health is passed to the data acquisition identification module, by the data acquisition identification module carry out the data pre-service, multi-sensor data merges with identification etc.Single-chip microcomputer is given data processing module data upload, data processing module is to the buffer memory of data, type according to control information, carry out the corresponding communication agreement, data are carried out respective coding and encapsulation, data after the encapsulation enter transmission network via input/output module, arrive the outer monitoring central host at last.
Downlink data: mainly be the instruction data.Receive the director data that sends from monitoring host computer on the input/output module of equipment, control module is resolved director data, and according to instruction, data processing module, data acquisition identification module is sent operational order.
