Abstract
The utility model discloses an electromagnetic balance adopting a USB interface, which comprises an electromagnetic balance measuring component, a signal isolating component and a USB interface module. The electromagnetic balance measuring component is connected with the signal isolating component, so as to transmit data information to the signal isolating component. The signal isolating component is connected with the USB interface module, so as to transmit the isolated data information to the USB interface module and output the data information through the USB interface module. The electromagnetic balance is connected with an external computer by the USB interface when in use, which not only effectively lessens the interference caused by noise at the inner part of the PC, but also saves the cost for isolating a power supply, thereby reducing the cost of the isolating technology and being beneficial for controlling the product cost.
Description
Technical field
The utility model relates to a kind of electromagnetic type balance, especially a kind of electromagnetic type balance that adopts USB interface.
Background technology
The electromagnetic type balance is the high-accuracy instrument of a kind of precision up to parts per million (ppm).In traditional electromagnetic type balance, the measurement component of electromagnetic type balance directly links to each other by RS232 interface and supply line with level converter, directly import outer computer (PC) from the data message of level converter output by the RS232C interface, as shown in Figure 1.Owing to do not adopt isolation technology, in case directly link to each other, be subjected to the interference that cause PC inside easily with PC, the accuracy of its reading is caused adverse effect.To an improvement of traditional electromagnetic type balance is to adopt traditional partition method, as shown in Figure 2, the insulating power supply of between the measurement component of electromagnetic type balance and level converter, connecting, insulating power supply and Signal Spacing parts are in parallel.But insulating power supply costs an arm and a leg, and adopts insulating power supply to be unfavorable for cost control.
Therefore, the interference that provides a kind of internal noise that both can reduce PC to cause, the electromagnetic type balance that helps cost control has again become those skilled in the art's target.
The utility model content
The technical matters that the utility model mainly solves is to provide a kind of electromagnetic type balance that adopts USB interface, both can reduce the interference that the internal noise of PC causes, and helps the control of cost again.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of electromagnetic type balance that adopts USB interface is characterized in that, comprising: electromagnetic type balance measurement parts, Signal Spacing parts and usb interface module; Described electromagnetic type balance measurement parts link to each other with the Signal Spacing parts, in order to data message is sent to described Signal Spacing parts; Described Signal Spacing parts link to each other with usb interface module, are sent to described usb interface module in order to the data message after will isolating, and this data message is exported by usb interface module.
Further, described usb interface module comprises USB interface chip that power supply output is provided and the USB interface that is attached thereto.
Further, described USB interface chip is for providing the USB interface chip of 5V/500mA power supply output.
Further, described electromagnetic type balance measurement parts are connected by the RS232 interface with described Signal Spacing parts.
Preferably, the electromagnetic type balance of described employing USB interface also is provided with display screen, and it links to each other with described electromagnetic type balance measurement parts, is used to the data message that shows that described electromagnetic type balance measurement parts send.
Preferably, the electromagnetic type balance of described employing USB interface also is provided with load module, and it links to each other with described electromagnetic type balance measurement parts, is used for to described electromagnetic type balance measurement parts input configuration information.
Compared to prior art, the beneficial effects of the utility model are: the USB interface by usb interface module when this electromagnetic type balance uses links to each other with outer computer, compare with traditional isolation technology, its Signal Spacing parts and outer computer are connected in series by USB interface.Because the reliability of USB interface and speed are all than traditional serial port height, and USB interface itself provides the power supply output of 5V/500mA, if adopt isolation technology like this, just can save the cost of insulating power supply, reduced the cost of isolation technology, so the interference that the internal noise that adopts technical scheme provided by the utility model not only can effectively reduce PC causes, and help the control of cost of products.

Embodiment
Further describe specific embodiment of the utility model below in conjunction with accompanying drawing:
Please referring to Fig. 3, a kind of electromagnetic type balance that adopts USB interface, it comprises: electromagnetic type balance measurement parts 10, Signal Spacing parts 20 and usb interface module 30; Described electromagnetic type balance measurement parts 10 link to each other with Signal Spacing parts 20, in order to data message is sent to described Signal Spacing parts 20; Described Signal Spacing parts 20 link to each other with usb interface module 30, are sent to described usb interface module 30 in order to the data message after will isolating, and make this data message by usb interface module 30 outputs.
Wherein, described usb interface module 30 USB interface 302 that comprises USB interface chip 301 and be attached thereto.USB interface chip 301 itself can provide the power supply output of 5V/500mA.Described electromagnetic type balance measurement parts 10 are connected by the RS232 interface with described Signal Spacing parts 20.
In the present embodiment, the electromagnetic type balance of described employing USB interface also is provided with display screen 40, for example LCD display etc.This display screen 40 links to each other with described electromagnetic type balance measurement parts 10, is used to the data message that shows that described electromagnetic type balance measurement parts 10 send, such as the weight etc. of survey object.
