The registration of electronic weighing device, is mainly used in the information registering electronic weighing device on the server, is particularly useful for the situation that a station server can revise the acceleration of gravity of multiple stage electronic weighing device.Wherein, each electronic weighing device is all identify the unique identities of oneself by sequence number, and namely electronic weighing device is different, and sequence number is different.The registration of electronic weighing device, see Fig. 1, comprises the steps:
Step 101, electronic weighing device judge whether to store 8 bit sequence number, if so, perform step 105, if not, perform step 102.
Step 102, electronic weighing device judge whether to store MAC Address (hardware address of machine), if so, perform step 104, if not, perform step 103.
Step 103, electronic weighing device receive the MAC Address of user's input of electronic weighing device.
Step 104, electronic weighing device receive 8 bit sequence number of user's input of electronic weighing device.
8 bit sequence number are sent to server by network by step 105, electronic weighing device.In this step, the out of Memory (as hardware configuration, software version etc.) of electronic weighing device also can be sent to server by electronic weighing device simultaneously.
8 bit sequence number of step 106, server stores electronic weighing device.If also have out of Memory, also store in the lump.
The demarcation of acceleration of gravity first, is mainly used in electronic weighing device and gets rid of other calibration of measuring outside acceleration of gravity factor and obtain one for the control code of certification correction acceleration of gravity authority, see Fig. 2, comprise the steps:
Step 201, electronic weighing device produce one first random code, and the first request being used for this first random code and one to obtain this control code is sent to server.
This first random code is encrypted as double secret key control code by step 202, server, and the control code through encryption is sent to electronic weighing device.
The control code deciphering that this first random code gets as double secret key by step 203, electronic weighing device, and the control code after store decrypted.
Step 204, electronic weighing device carry out Zero calibration.This step prior art can realize, and does not repeat them here.
Step 205, electronic weighing device carry out full amount demarcation.This step prior art can realize, and does not repeat them here.
Step 204,205 and step 201-203 do not influence each other, step 204,205 performed before step 201 also can.
The correction of long-range acceleration of gravity, is mainly used in the position setting acceleration of gravity according to electronic weighing device place, to ensure the accuracy of weighing.Whether performing the correction that this flow process carries out acceleration of gravity in the present embodiment is determined by the user of electronic weighing device, namely only after electronic weighing device obtains the first external command of a correction acceleration of gravity, just start to perform following steps, see Fig. 3:
Step 301, electronic weighing device produce one second random code, and the form that this second random code and this first external command are wrapped with TCP (TransmissionControlProtocol, transmission control protocol) by forwarded to server.
Step 302, server are by sending the position of the IP address location electronic weighing device of TCP bag, and this position comprises city name.(if IP address is 58.246.73.70, orientating Shanghai as) this step prior art can realize, therefore not repeat them here.
Step 303, server obtain latitude and the sea level elevation of this position by city name, calculate the acceleration of gravity of this position.(Shanghai is north latitude 31 degree 11 points, and sea level on the average is 4 meters, and calculating acceleration of gravity is 9.794m/s
2) this step prior art can realize, therefore not repeat them here.
This second random code is carried out re-encrypted as double secret key control code by step 304, server, and the acceleration of gravity (9.794m/s that will get
