Plate is the hot spot oneself built, then reports oneself the machine hotspot name, if it is the work wifi hotspot for using dining room, then
Report the work wifi hotspot title oneself connected；
Flat sheet mould is added, when needing to order together using other plate addition for same table guest, by waiter at this
The table number to be added is selected on other plate, is clicked and is added；Then corresponding 4 digit is generated according to the table number mapping chosen to make
The port numbers that service is monitored for udp broadcast, judge network wifi open state, if the wifi has turned on, and connect
Wifi hotspot is the hotspot name of corresponding table number, then obtains the local address network interface card dynamic ip, and with 4 digits of table number coding mapping
Port numbers create the service of udp broadcast listening, and prompt that desk success is added；If wifi is not yet turned on or has not yet connected
Network is imitated, then initializes wifi and reopens wifi, and generate hotspot name with the table number for the addition chosen, Dynamic link library should
Wifi hotspot title, the preconfigured password of password system；If the hot spot Dynamic link library for connecting the table number is unsuccessful, need
The hotspot name that the table number is used is obtained from Cloud Server by table number to be attached, after successful connection and utilize the addition
The 4 digit port numbers that table number generates create the service of udp broadcast listening, and prompt that desk success is added；If connect hot spot at
Function then obtains local network interface card dynamic ip, and the 4 digit port numbers generated using the addition table number, creation udp broadcast listening clothes
Business, and prompt that desk success is added；The listening port so generated by the wifi connection established and table number, forms with table number
Centered on local communication network；
Synchronization module, when user orders dishes, before menu places an order, menu information is entirely localized at the local communication network of this table
In, it is synchronized merely with the local communication network, when wherein a plate selection places an order, data can be submitted to backstage is
System, while lower single synchronization notice information is issued, notice other plates of deskmate update is ordered dishes as tapeout state.
4. the system that a kind of deskmate dining more plates of personnel according to claim 3 are ordered simultaneously, it is characterised in that: described
Synchronization in synchronization module before menu places an order is specifically:
When one of plate ordered dishes, modify order dishes, delete ordered dishes when, according to the address the machine ip that the machine obtains, shape
At the LAN broadcast address of xxx.xxx.xxx.255, and the port numbers generated with the table table number, send " ordering dishes for the port
Information ", " modification is ordered dishes ", " deletion has been ordered dishes " broadcast；
Udp broadcast listening service of the plate of other same tables due to having been set up the port in advance, then can receive at once
Synchronizing information updates local menu list；If it is have begun order dishes after the plate that is added, then need according to addition office
After the success of portion's network, an initialization is requested to put information request, so that the plate being added will receive menu latest update
Information conveniently checks the vegetable that others has selected so that menu is synchronous for holding；To realize synchronization.
