Description

A kind of temperature measuring apparatus
Technical field
The utility model relates to the monitoring temperature field, specifically a kind of temperature measuring apparatus.
Background technology
The measurement of temperature parameter and processing are the important steps of commercial production and experiment, and the measurement of temperature parameter generally adopts the intelligent temperature instrument to carry out.But the intelligent temperature instrument of prior art is all having very strong dependence to computer aspect the figure demonstration of temperature data post-processed and temperature data, this makes all needs to dispose the computer of a costliness in some single temperature surveys, not only take a large amount of spaces, and improved cost.Simultaneously, when temperature survey, some normality temperature ranges can adopt digital temperature sensor, and digital interface temperature sensor price commonly used is low, but range is little, response speed is slow; Be exceedingly fast in temperature variation, under extreme temperatures or the extremely low measurement environment, must use analog temperature sensor, the analog temperature sensor price is higher, but applied widely, response speed is fast, therefore need to prepare two kinds of different temperature sensors and use in order to different environment, also increased cost.
The utility model content
Cost high and that cause according to different measuring environment replacing intelligent temperature instrument improves problem to computer dependency in order to solve existing intelligent temperature instrument, and the utility model provides a kind of temperature measuring apparatus.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of temperature measuring apparatus, comprise arm processor, be used for the SRAM of the temperature data that real-time storage gathers, the LCDs that is used for realizing man-machine interaction, two digital temperature sensors, two analog temperature sensors and button, described arm processor inside is provided with two analog-digital converters and is used for providing the RTC module of timing to system;
Described arm processor receives the input information of button by signal input port, arm processor passes through signal output port output information to LCDs, two analog-digital converters of arm processor inside receive the information of the transmission of two analog temperature sensors respectively, and arm processor also carries out message exchange with SRAM and two digital temperature sensors respectively by data bus.
Described arm processor is provided with SD clamping mouth, and it is standby to be used for storing data into the SD card.
Described arm processor be provided with for the RS232 interface of compunication, be connected with the peripheral hardware computing machine by this RS232 interface, so that the mass disposal data.
Described arm processor is ARM Cortex-M3 type processor, and ARM Cortex-M3 type processor has good support to various real time operating systems, can smoothly move embedded real-time operating system and various GUI; The use of ARM Cortex-M3 type processor makes the figure of temperature data post-processed and temperature data show and can independently finish by separating computer, and does not increase the cost of instrument.
In the utility model, button is used for function and selects and system's setting.
In the utility model, digital temperature sensor converts the temperature signal of gathering to digital signal, the direct reading temperature data of arm processor; Analog temperature sensor converts the temperature signal of gathering to voltage signal, and arm processor is by internal simulation digital quantizer reading temperature data; The interface of temperature sensor too much can cause the instrument volume bigger, and consider that local temperature survey mostly is two measurement points, more the spatial extent of multimetering is bigger, the sensing data line is long can influence data precision, so the digital temperature sensor in the utility model and analog temperature sensor are two.
Beneficial effect: the utility model has been realized instant processing to temperature data having reduced the dependence of externally establishing computing machine by built-in arm processor, has improved efficient; Simultaneously, inside is provided with digital temperature sensor and analog temperature sensor, and its adaptability to environment is improved, and has reduced cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, a kind of temperature measuring apparatus, comprise arm processor, be used for the SRAM of the temperature data that real-time storage gathers, the LCDs that is used for realizing man-machine interaction, two digital temperature sensors, two analog temperature sensors and button, described arm processor inside is provided with two analog-digital converters and is used for providing the RTC module of timing to system;
Described arm processor receives the input information of button by signal input port, arm processor passes through signal output port output information to LCDs, two analog-digital converters of arm processor inside receive the information of the transmission of two analog temperature sensors respectively, and arm processor also carries out message exchange with SRAM and two digital temperature sensors respectively by data bus;
In the utility model, use for the ease of data are stored in the SD card, arm processor is provided with SD clamping mouth;
For the ease of handling large batch of data and carrying out some complex calculation, arm processor is provided with the RS232 interface, is connected with the peripheral hardware computing machine by this RS232 interface;
Above arm processor preferably adopts ARM Cortex-M3 type processor.
The utility model in use, arrange by button according to measurement environment earlier, mainly be that measurement pattern (adopting digital temperature sensor or analog temperature sensor) and Measuring Time are set, digital temperature sensor converts the temperature signal of gathering to digital signal then, the direct reading temperature data of arm processor, perhaps analog temperature sensor converts the temperature signal of gathering to voltage signal, arm processor is by internal simulation digital quantizer reading temperature data, arm processor is stored in the temperature data that reads in the SRAM, handle the temperature data of storage the back of finishing to be measured, and result is exported on LCDs; Or temperature data is passed to the peripheral hardware computing machine by the RS232 interface handle.
