Abstract
The invention provides a barcode scanning device having a temperature-regulating module. The barcode scanning device comprises a processor, an imaging module, an imaging lighting module, a plurality of thermocouples and a controller which are arranged on the scanning device circuit board. When the thermocouples are used to detect that the problems in the scanning device reaches a threshold value, the cooling mechanism of the scanning device is started by the controller. The barcode scanning device having a temperature-regulating module of the invention can be used to allow the scanning device tobe portioned in high ambient temperature conditions, the service life of the barcode scanning device can be prolonged and the optimized scanning performance can be maintained; and on the other hand, for wireless scanning products, the barcode scanning device of the invention can also be used to prolong the service life of the batteries of the wireless scanning products.
Description
Technical field
The present invention relates to automatic identification technology field, particularly a kind of bar code scanner with temperature adjustment module.
Background technology
Automatic identification technology is applied to a plurality of fields, such as retail, supermarket, storehouse management, logistics etc., utilize automatic end of identification to carry out data acquisition, the problems such as the speed that greatly solved artificial data input is slow, the bit error rate is high, labour intensity is large, the simple repeatability height of work, for providing, computer information processing carries out quickly and accurately the effective means of data acquisition input, therefore, automatic identification technology, as a kind of revolutionary new and high technology, is accepted by people just rapidly.Automatic recognition system transfers data to background process computing machine by intermediate equipment (comprise software with hardware), by computing machine, collected data is processed or is processed, and finally forms people's Useful Information.The most frequently used automatic identification equipment is bar code scanner at present, and along with the continuous progress of technology and the continuous expansion of applied environment, the performance of bar code scanner is more and more higher.
High performance bar code scanner was easy to produce higher temperature and then reduction or affects the performance of equipment in when work; In addition, high environment temperature also can affect the scan performance effect of equipment or cause product failure; Therefore, need to adapt to the high-performance bar code scanner of various environment temperatures.
Summary of the invention
The object of this invention is to provide a kind of bar code scanner with temperature adjustment module, it can adapt to the user demand of varying environment temperature.
To achieve the object of the present invention, the bar code scanner with temperature adjustment module of the present invention comprises the processor being arranged on scanister circuit board, imaging modules, imaging lighting module, a plurality of thermopairs and controller, when the problem that detects scanister inside when described thermopair reaches a threshold value, described controller starts the heat engine system of falling of scanister.
Preferably, described thermopair adjoins processor and/or the setting of imaging lighting module on circuit board.
Preferred again, the described heat engine system of falling comprises clock frequency or reduction storage drive power or reduction lighting current or the reduction frame rate that reduces central processing unit.
Preferred again, described bar code scanner also comprises LED light, and when the described heat engine system of falling starts, described LED light is sent indicator signal.
The bar code scanner with temperature adjustment module of the present invention can allow scanister in the higher situation operation of environment temperature, extends the serviceable life of bar code scanner and the scan performance that maintains optimization; On the other hand, for without line sweep product, the present invention can also extend the serviceable life of its battery.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the present invention is aforesaid will be become apparent with other object, feature and advantage.Wherein:
Figure 1 shows that the structural representation of internal circuit board of the bar code scanner with temperature adjustment module of one embodiment of the invention.
Embodiment
In conjunction with embodiment and accompanying drawing describes structure of the present invention in detail and feature is as follows:
The structural representation of the internal circuit board of the bar code scanner with temperature adjustment module of one embodiment of the invention as shown in Figure 1, the bar code scanner with temperature adjustment module of the present embodiment comprises the processor 34 being arranged on scanister circuit board 32, imaging modules 110, imaging lighting module 56, a plurality of thermopairs 44 and controller 40, when the problem that detects scanister inside when described thermopair 44 reaches a threshold value, described controller 40 starts the heat engine system of falling of scanister.
One preferred embodiment in, described thermopair 44 adjoins processor 34 on circuit board and/or imaging lighting module 56 arranges.
The heat engine system of falling described in the present embodiment comprises clock frequency or reduction storage drive power or reduction lighting current or the reduction frame rate that reduces central processing unit.
Another preferred embodiment in, described bar code scanner also comprises LED light (not shown), when the described heat engine system of falling starts, described LED light is sent indicator signal.
The bar code scanner with temperature adjustment module of the present invention carrys out initiatively to start by the monitoring temperature of scanister inside or the temperature of key components and parts the heat engine system of falling, reduce the performance of some service part or close some function, such as effectively reducing temperature by reducing the velocity ratio active as next in the travelling speed of processor or storer of equipment.
The present invention can extend the use equipment of bar code scanner and the scan performance that maintains optimization, allows scanister in the situation that higher situation or the equipment operation of environment temperature causes high temperature to move; On the other hand, for wireless product, the present invention can also extend its battery.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention openly in scope, still can do some corrections or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
