Technical solution of the present utility model is: a kind of dining room menu processor is characterized in that:

A, be connected to memory under program 2 with single-chip microcomputer 1, data memory 3 and random memory 4, memory under program 2 joins with data memory 3;

B, with single-chip microcomputer 1 be connected to interface circuit 7;

C, with single-chip microcomputer 1 be connected to display circuit 8;

D, with random memory be connected to photoelectric pen 5 and function key 6.

Described photoelectric pen 5 is joined by bar code scanner 11 and code translator and forms, and described display circuit 8 joins for lcd driver 9 and LCD 10 and forms.

Described function key 6 forms for resistance R 8-R11 and table options button K1, input, run-out key K2, K3 and menu display key K4 join.

The utility model compared with the prior art, can read the total charge of the dish number of having order easily, and can arbitrarily adjust the menu and the amount of money of selecting to be suitable for own requirement, waiter can be many customer services simultaneously, not only improved efficiency of service, guaranteed service quality, also improved the dining room, play a part very improving the dining room management in client's prestige in the heart.

Accompanying drawing 1 is the block diagram of dining room with the menu processor.

Accompanying drawing 2 is the circuit theory diagrams of dining room with the menu processor.

Below in conjunction with drawings and Examples, the utility model is further described.

As shown in Figure 1 and Figure 2, be connected to memory under program 2 with single-chip microcomputer 1, data memory 3 and random memory 4, memory under program 2 joins with data memory 3;

Single-chip microcomputer 1 can be selected 80C31BH for use, and memory under program 2 can be selected 2864A for use, and data memory 3 can be selected 74LS373 for use, and random memory is selected B1C55 for use.

Entire circuit is by powered by direct current.

Principle of work: read menu signal by photoelectric pen ［ 5 ］, input random memory ［ 4 ］, and according to the menu information that prestores (menu numbering, unit price) after single-chip microcomputer ［ 1 ］ carries out data processing, deliver on the LCD ［ 10 ］ through lcd driver ［ 9 ］ on the one hand, show the order dishes quantity and the amount of money, single-chip microcomputer ［ 1 ］ is sent to the dining room supervisory computer by interface circuit ［ 7 ］ with data and carries out aggregation process and print menu on the other hand, accepts the menu signal and the control signal of computing machine input simultaneously.

After client entered the dining room and sits down, the table that waiter sits down according to client number was with the table options button K1 of menu processor setting, give and put a table number also pinning.Give client then, serve the menu that has the stripe shape coding simultaneously, client likes according to oneself, with photoelectric pen ［ 5 ］ scanning name of the dish bar code, the dining room promptly is translated into binary code with bar code automatically with the menu processor, input random memory ［ 4 ］, and read the unit price of corresponding name of the dish, carry out data processing after driver ［ 9 ］ control LCD ［ 10 ］ by single-chip microcomputer ［ 1 ］, demonstrate client the table number, the quantity of ordering dishes total charge, if client to revise can cancel this name of the dish with photoelectric pen ［ 5 ］ reverse read name of the dish voluntarily by single-chip microcomputer 1 when putting name of the dish, and give demonstration.

Behind the selected menu of client, waiter presses run-out key K3 with the menu processor, carries out data communication by interface circuit ［ 7 ］ and dining room supervisory computer.Realize menu unloading, gather, print, simultaneously, the dining room is latched to this customer data with the menu processor, until checking out, miss mistake to prevent data.Waiter can select for use and be other customer service new number, and a dining room can be 99 customer services with the menu processor simultaneously.

When client have a dinner finish after, waiter finishes the gathering of menu, checks out, behind the list print, sends the signal that clears data simultaneously to the menu processor by the dining room supervisory computer, the memory block of the corresponding table of corresponding removing number.

When the menu kind in dining room changes, by computer input signal to single-chip microcomputer ［ 1 ］ and be transferred to program and data memory ［ 3 ］ on, upgrade and increase the signal of corresponding menu.
