Abstract

The utility model relates to a temperature recorder, and particularly discloses a single-key min temperature recorder which comprises a shell. The two sides of the shell are provided with temperature-measuring ventilating holes. A single chip microcomputer is mounted inside the shell, and a power management module, a temperature measurement module, a clock module, a storage module, a displaying device, a communication module and a USB (universal serial bus) interface are connected with the single chip microcomputer respectively. With single-key operation and temperature measurement by the ventilating holes, an internal battery can be applied to occasions without a power supply source and strictly requiring space. In addition, the single-key mini temperature recorder with the USB interface is more universal.

Description

The mini TR of singly-bound

Technical field

The utility model relates to a kind of TR, specifically is the mini TR of a kind of singly-bound, is specially adapted to place temperature such as food, medicine, cold chain transportation are carried out long-term process record.

Background technology

In modern society; Implementation along with the HACCP authentication; Thermograph requirements at the higher level have been proposed; We no longer are satisfied with the measurement of temperature in industries such as freezing and refrigeration, cold chain transportation, health care, greenhouse management, aquatic animal cultivating, food accumulating, historical relic preservation, building materials experiment, climatic data, health care and field, and the demand in market has caused the birth of TR.The producer that produces TR at present is more; Though some registering instrument product has strong functions; But it costs an arm and a leg; Can't miniaturization, need reason such as external power supply to cause on the market consumption little, can not obtain popularizing and being applied in some no power supplies and to the space requirement special occasions of strictness.It is inconvenient that the small-sized registering instrument of some that see is in the market changed battery, do not have symmetrical bleeder vent quick temperature measurement, needs external power supply.

Summary of the invention

In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of singly-bound mini TR, can be applied in some no power supplies easily and reach the strict special occasions of space requirement.

The utility model is realized with following technical scheme: the mini TR of a kind of singly-bound; Comprise a housing, single-chip microcomputer is installed in the housing, comprise a housing; Single-chip microcomputer is installed in the housing; The temperature-measuring module that is connected with single-chip microcomputer is used for measures ambient temperature, with the temperature signal input single-chip microcomputer of gathering; The clock module that is connected with single-chip microcomputer, interior band clock/calendar; The memory module that is connected with single-chip microcomputer is used for storing temperature data and systematic parameter; The display device that is connected with single-chip microcomputer is used for each duty and running marks such as display alarm information, recording status, calendar and temperature value; The key-press module that is connected with single-chip microcomputer is used to start/stop record and check duty; The communication module that is connected with single-chip microcomputer is used for data transmission with registering instrument in computing machine; The power management module that is connected with single-chip microcomputer is used for power supply being provided and carrying out the low-power consumption management to each element circuit; Connect one on the single-chip microcomputer and be used to upload the data USB interface; Key-press module adopts single button operation to be used to start/to stop to write down and checking duty; The symmetria bilateralis of housing is provided with the thermometric bleeder vent.

The beneficial effect of the utility model is: single key stroke, bleeder vent thermometric and in establish that battery can be applied in some no power supplies easily and to the strict occasion of space requirement, self-carried USB interface own, the use of this product has more general property.

Embodiment

As shown in Figure 1, the mini TR of singly-bound has a housing 4 by power management module, and the both sides of housing are provided with thermometric bleeder vent 1, the both sides that are arranged on housing of fast thermometric bleeder vent 1 symmetry, and symmetry is attractive in appearance and data recording is reliable.Display device 2 is installed on the housing, is convenient to observe.Key-press module 3 adopts single button operation to be used to start/to stop to write down and checking duty, and single key stroke is convenient and swift.USB interface 5 is installed on the housing 4, uses to have more general property.Built-in hanging hole on the housing 4, convenient suspension.

As shown in Figure 2, the mini TR of singly-bound comprises power management module, temperature-measuring module, clock module, memory module, display device, key-press module, communication module and single-chip microcomputer; Above-mentioned module is installed in the housing.The residing environment temperature of temperature-measuring module survey record appearance.The system clock of clock module logout appearance is to guarantee the accuracy of writing time.Memory module with the thermograph of measuring in the registering instrument storer.Display device is used to show each duty and running mark.Key-press module is used to start/stops to write down and checking duty.Communication module is used for data transmission with registering instrument in computing machine.Power management module carries out strict timesharing management to each module for power supply, has guaranteed the low-power consumption of system.

As shown in Figure 3, in the present embodiment, single-chip microcomputer adopts the UPD78F0411 single-chip microcomputer of NEC Corporation, less encapsulation, and lower power consumption, interior band real-time clock and serial port function provide possibility for the registering instrument miniaturization.。Temperature-measuring module adopts the thermosensitive resistance measurement temperature, has reduced volume, and connector has been saved in interior postpone, has strengthened the sealing of housing.Battery adopts wide temperature CR2450 lithium battery, and capacity is big, and volume is little, and temperature range is wide, for registering instrument is applied in some no power supplies and to the strict occasion of space, environmental requirement possibility is provided.Display device adopts liquid crystal display, multimode indicated number registering instrument current information.When measures ambient temperature surpasses bound is set, the pilot lamp flicker is reported to the police.
