Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains the present invention, it is not limited to the present invention.
Fig. 1 is the structural representation of the weight bridge weighing device prevented cheating provided by the invention.As it is shown in figure 1, the present invention provides a kind of weight bridge weighing device prevented cheating, the weight bridge weighing device that this prevents cheating includes: LOAD CELLS 1, is used for carrying out weighing to produce weighing data analogue signal；Weighbridge controls module 3, is connected with described LOAD CELLS 1 and described data transmission module 4, for weighing data analogue signal is converted to weighing data digital signal；Encrypting module 6, controls module 3 with described weighbridge and is connected, for being encrypted by the described weighing data digital signal after conversion；Data transmission module 4, for transmitting the weighing data digital signal of encryption；Deciphering module 5, is connected with described data transmission module 4, for the weighing data digital signal of described encryption is decrypted；Weighing instrument 2, is connected with described deciphering module 5, is used for showing weighing data.
LOAD CELLS 1 detects product data of weighing, and in more piece weighbridge, the electric bridge being made up of multiple foil gauges, in order to drive these electric bridges, it is necessary to sensor circuit provides enough and stable bridge excitation electric currents.The present invention is preferred, and strain gauge bridge pumping signal adopts AD588 chip composition, and AD588 is high-precision reference voltage source, and reference voltage provides excitation power supply for electric bridge after amplifier, audion expand stream.
Analogue signal is weak due to capacity of resisting disturbance, therefore easily it is affected and distorts, the device that weighing data is distorted in remote control is had to be installed in LOAD CELLS 1 or weighing instrument 2 now, send the analogue signal of radiofrequency signal impact transmission or directly adjust the data of weighing instrument 2, making weighing data be changed with remote control.Thus while the product data of weighing that LOAD CELLS 1 of the present invention provides is analogue signal, but using weighbridge control module 3 that this weighing data analogue signal is made directly digital-to-analogue conversion is weighing data digital signal, owing to adopting digital data transmission weighing data, the signal making transmission weighing data is more stable, it is possible to prevent the device that weighing data is distorted in the remote control being arranged in LOAD CELLS 1 from sending radiofrequency signal and weighing data is distorted.
After weighing data is converted into weighing data digital signal, recycling encrypting module 6 is by this weighing data digital signal encryption (present invention preferably employs des encryption module to be encrypted), and the weighing data digital signal of encryption is sent to deciphering module 5 by data transmission module 4 afterwards.
Preferably, after to weighing data digital signal encryption, it is possible to use this weighing data digital signal is carried out parallel-serial conversion by parallel serial conversion module, in order to long distance transmission serial data signal.Furthermore it is preferred that data transmission module 4 can be differential digital transport module, utilizing difference chip that single-ended signal is carried out differential conversion, transmission cable adopts general twisted-pair power cable, it is ensured that the reliability of data long distance transmission.
The weighing data digital signal received is decrypted by deciphering module 5, is sent to weighing instrument 2.If having carried out differential conversion and serioparallel exchange before transmission weighing data digital signal, then it is also required to before decryption carry out differential conversion and serioparallel exchange.
Described deciphering module 5 becomes one with described weighing instrument 2.Deciphering module 5 has the functions such as deciphering, differential conversion and serioparallel exchange, weighman can only use unique one piece of instrument, weighing data will be made if one want to change weighing instrument 2 to show to obtain illegitimate benefits, it is prevented that weighman personnel adopt the weighing instrument 2 being provided with the device that weighing data is distorted in remote control that weighing data is distorted.
Preferably, the weight bridge weighing device that this prevents cheating also includes signals revivification module, is connected with described deciphering module 5 and weighing instrument 2, for weighing data digital signal is converted to weighing data analogue signal.When weighing data digital signal is after deciphering module 5 is deciphered, the difference according to weighing instrument 2, choose whether to utilize signals revivification module that weighing data digital signal is reduced to weighing data analogue signal.When weighing instrument 2 needs analogue signal, weighing data digital signal is reduced to weighing data analogue signal by signals revivification module, when weighing instrument 2 needs digital signal, it is possible to directly receive the weighing data digital signal after deciphering.
Preferably, the weight bridge weighing device that this prevents cheating also includes data memory module, is connected with described LOAD CELLS 1, is used for storing weighing data and/or being uploaded by this weighing data.The weight bridge weighing device that this prevents cheating also includes article monitoring device of weighing, and is recorded for symmetrical heavy articles information, and this information associates storage or uploads with weighing data.After data memory module is filled with data, the data preserved before covering according to the method first abolished first.Article monitoring device of weighing can be the device such as video camera or RF Reader, can recognise that Item Information of weighing is for excellent, weigh article monitoring device and data memory module uploads Item Information of weighing (such as representing sequence number or the numbering of these article of weighing) and weighing data to Surveillance center by wireless network, Surveillance center controls real weighing data, the weighing data contrast of corresponding sequence number that this real weighing data reads or numbering can be used with weighman personnel, it is prevented that weighman's personnel reading does not record or records false data.
It addition, encryption of the present invention can be utilize any mapping mode (being such as multiplied by Any Digit, inverse transformation etc.), reach the purpose not having the transformation for mula of correspondence not decipher.Practise fraud if weighman personnel want to change weighing instrument 2, but new weighing instrument will not have decryption capabilities, even if design has deciphering function can not be used for being decrypted for the particular transform mode of this encryption, therefore prevent weighman personnel to change instrument and practise fraud.
Fig. 2 is the flow chart of the weight bridge weighing method prevented cheating provided by the invention.As in figure 2 it is shown, the present invention also provides for a kind of weight bridge weighing method prevented cheating, the method includes: carry out weighing to produce weighing data；Weighing data analogue signal is converted to weighing data digital signal；Weighing data digital signal after conversion is encrypted；The weighing data digital signal of transmission encryption；The weighing data digital signal of described encryption is decrypted；Display weighing data.
