Abstract
The utility model relates to a track temperature measuring instrument, which comprises a singlechip, a digital temperature sensor and a display. The digital temperature sensor and the display are both connected with the singlechip. Compared with the prior art, the utility model has the characteristics of simple structure, raid temperature measuring speed, accurate and reliable indicating value and convenient use and maintenance. Various performance indexes of the track temperature measuring instrument of the utility model are all superior to the original track temperature measuring instrument.
Description
Technical field
The utility model relates to orbit measurement, particularly relates to a kind of rail temperature measuring instrument.
Background technology
Present existing rail temperature meter comprises thermometal mechanical type and digital display type, and analog sensor and analog control circuit that digital display type rail temperature meter adopts, temperature measurement error are all big and error correction is difficult.The intelligent rail temperature meter power consumption of early stage development is big, the device and the technology of function singleness, employing do not consider to use and examine and determine the needs of debugging.As: single-chip microcomputer is a plug-in with being connected of circuit board, and it must be taken off just and can make amendment from circuit board when revising single-chip data, and loosening with regard to causing the plug number of times too much to produce easily like this, influence is normally used; The device power consumption macrocell is short service time, and does not have electric quantity indication function, and power supply capacity what can't be grasped, can be because of showing that the rail temperature influences operation when electric weight is low; Do not consider that night work do not have the problem of liquid crystal reading difficulty backlight.
Summary of the invention
Technical problem to be solved in the utility model is exactly to provide a kind of rail temperature measuring instrument for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of rail temperature measuring instrument is characterized in that comprise single-chip microcomputer, digital temperature sensor and display, described digital temperature sensor and display all are connected with single-chip microcomputer.
The utility model also comprises power supply, and this power supply is electrically connected with single-chip microcomputer, digital temperature sensor and display.
Described single-chip microcomputer is a caryogram single-chip microcomputer in 51 series.
Described digital temperature sensor is the wide voltage digital temperature sensor of DS18B20.
Described display is the LCD LCD.
Described power supply is a lithium battery.
Compared with prior art, the utility model is simple in structure, thermometric speed is fast, indicating value accurately and reliably, working service characteristics easily, its every performance index all are better than original rail temperature measurement instrument.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of rail temperature measuring instrument comprises single-chip microcomputer 1, digital temperature sensor 2 and display 3, and described digital temperature sensor 2 and display 3 all are connected with single-chip microcomputer 1.
The utility model also comprises power supply 4, and this power supply 4 is electrically connected with single-chip microcomputer 1, digital temperature sensor 1 and display 3; Described single-chip microcomputer is a caryogram single-chip microcomputer in 51 series; Described digital temperature sensor is the wide voltage digital temperature sensor of DS18B20; Described display is the LCD LCD; Described power supply is a lithium battery.
The wide voltage digital temperature sensor of DS18B20, its measurement temperature range are-55 ℃～125 ℃, and in-10 ℃～85 ℃ scopes, measuring accuracy is ± 0.5 ℃.
Single-chip microcomputer consider to adopt caryogram in 51 series, wide voltage (running environment of 3.0V～5.5V), built-in chip type EEPROM function, band A/D translation function.Can finish rail temperature measurement, demonstration, control, battery capacity indication and liquid crystal display background light control supervisor, satisfy requirements such as rail temperature instrumentation temperature, demonstration, delay switching-off, background light are closed automatically, error correction.
The LCD LCD, the segmentation liquid crystal display that this display has LED-backlit shows, the serial data input, among built-in four RAM, the numeral that shows three bit strip radix point, and a sign bit, sop is adopted in encapsulation, six pins are respectively power supply ground, serial-shift pulse, serial data input, positive source, backlight positive pole and negative pole.Presentation Function with rail temperature, battery electric quantity, charging.
Adopt the 3.7V low-power consumption, can charge and discharge the type lithium battery power supply, other main components and parts are selected low-power consumption too, can prolong the service time after the charging once like this.
