As preferably, described master controller comprises display, and described display is used for display and makes a reservation information and positioning result.
Wireless location food delivery system of the present invention has following characteristics:
1, intelligent power saving mechanism, in most cases, as shown in Figure 2, location meal board can be in the resting state of most power saving.Actual use procedure can be: client orders after payment, foreground personnel locate meal board (meal trade mark code typing formula order dishes system) to client, location meal board is picked up a moment and is risen, movement sensing module can perception wake the 3rd micro treatment module up and calculate continuous run duration (if when timing time is less than n second, 3rd micro treatment module thinks that meal board is ordered each module again to enter resting state to save power consumption by malfunction, otherwise then enter readiness for operation), find in the process of table client, location meal board moves together along with people, after finding table to sit down, eating in location, board is static to be positioned on desktop, from static that is carved, 3rd micro treatment module judges continuous static duration by motional induction module, if when duration is more than t second, 3rd micro treatment module controls the 3rd wireless data transceiver module and opens m second for receiving label data, the communication channel identical with locating base station is converted to and by data upload to backstage after gathering the data received, if duration does not reach t second, then think client just make a short pause also do not find want sit table.
Because in the meal board of location, during the 3rd wireless data transceiver module work, power consumption is comparatively large, and motion sensor work power consumption is very little, so utilize the necessary operating time of above machine-processed intelligent decision meal board, the saving of the electricity that is highly advantageous to.
2, convenient usability, in use, when location meal board starts location, position in which kind of situation and all carry out intelligent decision and management and control by the 3rd micro treatment module and motional induction module, make user in use, consistent operating habit can not be changed, namely taking board--to look for position--waits meal three step to complete, the product of contrast existing market, as insert card type (mentioning above) operating procedure, in order to take card,----plug-in card--waits meal four step to complete to look for position, and this step of the plug-in card increased client that needs to have dinner changes the custom of having dinner of " sit down wait meal just passable " of 1,100, card-inserted device meal card being inserted into desktop just can position, if with the non-plug-in card of any reason, cannot positioning function be completed, namely system becomes invalid.
3, high network stabilization, when locating meal board and carrying out data transmit-receive work, can use unlike signal channel, namely system supports two-way work.Operation principle is, location meal board except transferring to except locating base station same channel when locating base station sends data, and other operating states are the same channel with positioning label all.Reduce the terminal quantity of consolidated network channel, namely reduce offered load pressure, ensure that communication network is efficiently unobstructed.
4, meal board in location is provided with the low electricity prompting of software and hardware, namely during low electricity, the flashing light of meal board own is pointed out and is uploaded to daemon software interface prompt, because because of busy or viewing angle difference, meal board staff when being frequently used in location may not find that hardware flashing light is pointed out, and each food delivery, staff can check the positioning result of corresponding location meal board on master controller software, remind more directly effective so do low electricity on software interface, contrast traditional plain hardware prompting and have more protection.
5, environment for use adaptability is stronger, does not limit the meal board quantity simultaneously on same desk, does not namely limit and share a table with stranger, and can adapt to dissimilar and desk that is size.
6, applied environment protectiveness is stronger, and label is affixed on a bottom surface, without the need in desktop fixed placement, is conducive to saving desk-top space and preserving original desktop style characteristic.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
