The utility model content
The technical matters that the utility model solves is to provide a kind of intelligent comprehensive readout instrument, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
The intelligent comprehensive readout instrument, comprise single-chip microcomputer, jtag interface, clock circuit and power module, described jtag interface, clock circuit and power module link to each other with described single-chip microcomputer respective pins respectively, the I/O mouth of described single-chip microcomputer is connected with keyboard, memory module, vibrating string type sensor, temperature sensor, LCD display and displacement transducer respectively, and the UART interface of described single-chip microcomputer is connected with the RS485 module with the RS232 module respectively.
In the utility model, described memory module is E
2PROM chip and peripheral circuit.
Beneficial effect
The utility model is simple in structure, and Systems balanth system can be good, and cost performance is high, memory space is large, be convenient to for a long time sensor be carried out data acquisition, and the data obtained through after the least square method supporting vector machine technical finesse very near True Data, obtained good temperature compensation.
Description of drawings
Fig. 1 is the structural drawing of intelligent comprehensive readout instrument.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the structural drawing of intelligent comprehensive readout instrument, the intelligent comprehensive readout instrument, comprise single-chip microcomputer 1, jtag interface 2, clock circuit 3 and power module 4, described jtag interface 2, clock circuit 3 and power module 4 link to each other with the respective pins of described single-chip microcomputer 1 respectively, the I/O mouth of described single-chip microcomputer 1 is connected with keyboard 5, memory module 9, vibrating string type sensor 6, temperature sensor 7, LCD display 12 and displacement transducer 8 respectively, and the UART mouth of described single-chip microcomputer 1 is connected with the RS485 module with RS232 module 10 respectively and is connected.
In the utility model, described memory module is E
2PROM chip and peripheral circuit.By the least square method supporting vector machine technology vibrating string type sensor is carried out temperature compensation.
The utility model adopts RS232, and the bus interface such as RS485 are convenient to data communication, and this instrument can communicate by RS232 bus interface and host computer (PC) as slave computer; Simultaneously also can carry out data communication by RS485 bus interface and slave computer as host computer, the data that collect are reasonably processed.Processor adopting C8051F series monolithic is controlled each peripheral circuit, whole system running good stability, and cost performance is high.
Because the signal that collects is relevant with the material of sensor, it is larger that signal is affected by temperature factor, as not treated, resulting data error is larger, software in this instrument adopts the least square method supporting vector machine technology that the signal that collects is processed, so that the data after processing have obtained good temperature compensation very near True Data.And this instrument interface shows succinct friendlyly, and operability is stronger, have that detection speed is fast, measuring accuracy is high, simple to operate, volume is little, lightweight, low in energy consumption, the advantage such as service time is long, easy to carry.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model; the technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
