In one embodiment, when user updates operation (for example, addition commodity are extremely done shopping by carrying out order from POS terminal
Vehicle, clearing order etc.) when, it can be updated from POS terminal according to the order and operate corresponding order more new data generation order more
New request, wherein the order updates request and carries the order more new data, and then can send the order to main POS terminal
Update request.
In step s 302, the corresponding order data of the order note identification is carried out more based on the order more new content
Newly, updated order data is obtained.
In one embodiment, request is updated when main POS terminal receives the order that at least one above-mentioned POS terminal is sent
Afterwards, the corresponding order data of the order note identification can be updated based on the above order more new content, is obtained updated
Order data.
In one embodiment, main POS terminal can be to the corresponding order of the order note identification stored in local data base
Data are updated, to obtain updated order data.
In step S303, the updated order data is sent to each POS terminal.
In one embodiment, when main POS terminal is based on the order more new content to the corresponding order of the order note identification
Data are updated, and after obtaining updated order data, above-mentioned updated order data can be sent to described each
POS terminal.
In one embodiment, above-mentioned main POS terminal can pre-establish long connection with each POS terminal, and then work as and obtain
After updated order data, updated order data is sent to described each by the long connection that can be pre-established based on this
A POS terminal.
In step s 304, the list for recording the state of each POS terminal is obtained, in each POS terminal
It is stored with the corresponding access data of the data access request.
In step S305, the target POS terminal being in idle condition is determined from the list.
Wherein, the relevant explanation of step S304-S305 and explanation may refer to above-described embodiment, herein without repeating.
Seen from the above description, the present embodiment updates request, and base by receiving the order that at least one POS terminal is sent
The corresponding order data of the order note identification is updated in the order more new content, obtains updated order data,
And then the updated order data is sent to each POS terminal, each POS terminal in POS system can be synchronized
Database in the order data that stores, so as to realize target POS terminal that subsequent determination is in idle condition, and ensure
The corresponding access data of data access request are stored in the database of the target POS terminal.
In one embodiment, the method for above-mentioned access data can also include: based on the POS terminal and equipment constructed in advance
Corresponding relationship between address determines the device address of the target POS terminal, is said below based on embodiment illustrated in fig. 4
It is bright.
