Description
Technical field
The invention belongs to the IT product that is used for the dining room, particularly a kind of remote controlled dish ordering car.
Background technology
Along with the arrival of digital Age, the various digital information technical products that are used for the dining room have appearred, as wireless dish-order device, touch-screen dishes ordering device, electronic cookbook, service call device, private room VOD (video request program) system, or the like.
Adopt after the wireless dish-ordering system, the waiter in dining room or client can order dishes on various dishes ordering devices, by wireless network dishes ordering information are directly sent to the kitchen and print then and give the cook, thereby improved the efficiency of operation in dining room.
The product of Chu Xianing is the miniature hand-held dishes ordering device (often being called " treasured of ordering dishes ") that is used by waiter the earliest.Owing to when needing client to order dishes waiter's post is aside arranged, makes the dining room often more busy in the peak period.In addition, the inconvenience of papery menu is revised, the printing cost height, and depreciation also is potential problems soon.
At this problem, touch-screen dishes ordering device (perhaps being called electronic cookbook) has appearred, and this product can allow client oneself directly order dishes on touch-screen, need not waiter's post, and can change the menu content at any time, need not republish menu.This product is more attractive with regard to its function, but present product has a plurality of open questions, for example the cost height, break easily and lose, use inconvenience, thereby be difficult to promote.
The author is at the problem of existing touch-screen dishes ordering device, at patent application " a kind of table companion " (application number 200820178106.0, hereinafter be referred to as " invention A ") in a kind of employing large scale (generally being the 15-30 inch) panel display screen has been proposed, fully with telepilot operation, the product that supports by floor stand movably.This product is used for satisfying the dining room client when having dinner orders dishes, service, amusement needs, therefore is called " table companion ", perhaps is called " remote controlled dish ordering car ".Client can operate with telepilot, the very light comings and goings of cosily finishing.
There are the following problems for invention A.
First problem is invent A and operate with telepilot fully, and telepilot to be based on wireless transmission, so (for example malicious interference) wireless signal can be subjected to strong interference under special circumstances, even causes telepilot to lose efficacy.If telepilot lost efficacy, the client in dining room can't operate invention A, can't order dishes, and will have a strong impact on the dining room business.At this problem, invention A is provided with " standby input media " specially.When telepilot lost efficacy, client can continue operation invention A with standby input media.Standby input media can be the input media of arbitrary form, for example can be telepilot of simple and easy keyboard, mouse, touch-screen, another wave band etc.But obviously, the degree of flexibility of these standby input medias all far is worse than telepilot.For example, if use touch-screen, then customer need is being lifted the arm touch, and the client who only is sitting in invention A next door in addition could operate.In addition, changed input media suddenly, it is very uncomfortable that client can feel.Have, standby input media has obviously increased the volume of cost and invention A again.
Second problem is that the frequency of utilization of the telepilot of invention A is still than higher.Each button all can wake single-chip microcomputer and the radio communication circuit in the telepilot up, thereby can consume certain energy.Frequent button is exactly to make the battery consumption of telepilot must be than comparatively fast.As seen, can to change battery easily be important to invention A.Because invention A uses in public, so the battery of telepilot can not at will be dismantled, otherwise can be destroyed by some client.If battery can not at will be dismantled, then increased the trouble of dining room replacing battery.
The 3rd problem is that the telepilot of invention A generally adopts the wireless communication protocol of more complicated, thereby the firmware in the single-chip microcomputer of the invention A that need upgrade frequently unavoidably.For invention A, can only transmit and firmware updating by wireless.Because the reliability of radio communication is poor, potential problem also can be many, in case some problem appears in radio communication in escalation process, causes the firmware upgrade failure, then generally can only could recover by reprocessing.
The 4th problem is that generally speaking, invention A is general to realize wireless remote control with the wireless technology based on frequency hopping that is similar to bluetooth.The benefit of frequency hopping communications is: strong interference immunity, a plurality of wireless system may be simultaneously operated in the same frequency range (for example, the ISM band of 2405Mhz～2483Mhz) and can the phase mutual interference.Existing frequency-hopping communication system, bluetooth for example generally all has the very complicated matchmaking protocol of a cover, and the wireless connections relation is promptly set up in so-called pairing, for example sets up the radio communication relation (can with reference to the matchmaking protocol of bluetooth) of mobile phone and bluetooth earphone.Why complicated matchmaking protocol is, is that receiving-transmitting sides is jumping to certain channel at the same time together because frequency hopping communications requirement communicating pair carries out clock synchronization accurately.Since the latent instability of wireless system, in the time of actual the use, the unavoidable situation that the pairing failure occurs.Invention A generally has a lot of platforms to use simultaneously at the scene in dining room, therefore if solve bad marriage problem, and easy going wrong very just.
Summary of the invention
The present invention is directed to some problems of invention A, proposed a kind of remote controlled dish ordering car, it is characterized in that:
Its standby input media (5) is exactly a telepilot (2) itself;
Have telepilot cable interface (3) on main frame (1) and the telepilot (2);
Telepilot (2) can be connected to main frame (1) by telepilot cable (4);
When telepilot (2) was connected to main frame (1) by telepilot cable (4), telepilot (2) automatically switched to the wired remote control pattern, and telepilot this moment (2) becomes standby input media (5), carries out wire communication by telepilot cable (4) and main frame (1);
When telepilot cable (4) is pulled up telepilot (2), telepilot (2) automatically switches to the wireless remote control pattern, and telepilot this moment (2) becomes Digiplex (6), and telepilot (2) is believed by Radio Link and main frame logical (1).
Its feature also is: telepilot (2) built-in rechargeable battery and charging circuit; Have supply line in the telepilot cable; When telepilot (2) was connected to main frame (1) by telepilot cable (4), main frame (1) charged to telepilot (2) by telepilot cable (4).
Its feature also is: when telepilot (2) was connected to main frame (1) by telepilot cable (4), main frame (1) can carry out firmware update to telepilot (2) by telepilot cable (4).
Its feature also is: after telepilot (2) was received main frame (I) by telepilot cable company (4), main frame (1) can detect telepilot cable (4) disconnected event and report to the police.
Its feature also is: when the wire/wireless state of telepilot (2) changed, main frame (1) display message on screen was notified the user.
Its feature also is: the radio communication of telepilot (2) and main frame (1) is based on the frequency hopping communications technology; When telepilot (2) was connected to main frame (1) by telepilot cable (4), telepilot (2) or main frame (1) periodically sent current synchronous clock by telepilot cable (4) to the other side; When switching to wireless remote control, the synchronous clock that telepilot (2) and main frame (1) will have been set up under the wired remote control pattern is as initial frequency hopping synchronization clock.
The present invention can obtain following benefit.
First benefit is that telepilot itself just can serve as standby input media.When telepilot did not have to lose efficacy, client's operation that normally uses a teleswitch get final product, at this moment can obtain all advantages that telepilot brings, and for example need not lifting the arm touch, everyone can operate or the like.When telepilot lost efficacy, only need to connect main frame and telepilot with a cable, can continue to come operating host with telepilot.At this moment be equivalent to telepilot and become wired remote control, be similar to the handle of family's electronic game machine from wireless remote control.As seen, the telepilot effect of just having served as standby input media at this moment.In addition, also have several benefits with telepilot as standby input media.At first, reduce cost, need not other standby input media.The second, though be wired remote control, but still have the advantage of wireless remote control to a certain degree, for example need not lifting arm and touch, and as long as the operator is not far from main frame, still who can operating host.The 3rd, client is still in remote controller, thereby in fact input media does not change, and it is uncomfortable that client can or can not feel.
Second benefit is directly can be charged to telepilot by main frame by the telepilot cable.Designed " telepilot berth " specially in order to preserve telepilot on the invention A.Like this, in the time of the telepilot power shortage,, connect then and go up the telepilot cable, can begin telepilot is charged as long as usual telepilot is put back to the telepilot berth.Certainly, require this moment telepilot to use rechargeable battery and have charging circuit.As seen, because to plug cable promptly chargeable, thereby the battery design of telepilot becomes built-in getting final product, and can't dismantle, and effectively prevented client's destruction.As long as connect the telepilot cable, just automatically telepilot is charged.Certainly, also can design independent charge power supply interface on the invention A.
The 3rd benefit be, can very upgrade the telepilot firmware simply by the telepilot cable, and main frame is as long as send to telepilot to new firmware by the telepilot cable.The reliability of wire communication is far above radio communication, and communication protocol also can be very simple.
The 4th benefit is that the telepilot berth need not to have locking telecontroller again or detects the function that telepilot is removed.At ordinary times, as long as telepilot is placed on the telepilot berth, is connected to main frame by the telepilot cable simultaneously and charges.When telepilot is taken away in dining room client attempt, must disconnect the telepilot cable earlier, main frame can very find that like a cork cable is disconnected, and can send chimes of doom then, causes table steward's attention.As seen telepilot cable itself has just played the effect of burglar alarm.
The 5th benefit is that problem is set up in the connection that has solved frequency hopping communications.A is different with general bluetooth equipment in invention, its telepilot and main frame are one to one, and telepilot just is kept in the telepilot berth on the support of main frame, therefore do not need the address assignment of bluetooth the inside (to have only receiving-transmitting sides to know that all the other side's radio address could carry out radio communication mutually, the address refers generally to the MAC Address of wireless protocols herein), operation such as safety certification, parameters such as the telepilot of any main frame and the radio address of this main frame, security password all are to mate mutually, have only them to match.A telepilot can't and then be operated another main frame with another main frame pairing.Therefore, the key problem of setting up wireless connections is exactly how to have carried out clock synchronization.
The specific implementation method of setting up clock synchronization is that when telepilot was connected to main frame by the telepilot cable, telepilot or main frame periodically sent current local synchronous clock to the opposing party by the telepilot cable.Like this, what receive synchronous clock can periodically correct own local clock a side, thereby and the maintenance of the local clock of transmit leg synchronous.Having only a side to need to send synchronous clock, can be that main frame sends, and also can be that telepilot sends.Be noted that as mentioned before " main frame " herein refers to invent A the inside telepilot other parts in addition.Specifically, be that movement module and the telepilot in the main frame carries out wired and radio communication, specifically see also the instructions of invention A.The transmission cycle is depended on the tolerance of used crystal on the one hand, depends on the frequency hopping speed of used frequency hopping agreement on the other hand.The crystal tolerance is big more, frequency modulation speed is fast more, and the transmission cycle will be shorter.Concrete system of selection can be referring to the relevant textbook of frequency hopping communications.The actual used transmission cycle generally is several seconds.
Pull up when coming from the telepilot cable when telepilot, telepilot and main frame switch under the wireless mode separately, and this moment, employed initial frequency hopping synchronization clock had the synchronous clock that obtains under the ray mode before being exactly.Afterwards, also must contain synchronous timing information in the packet of used frequency hopping wireless agreement, thereby thereby can rely on the timing information in the wireless data packet to keep the maintenance of correction synchronous clock synchronously.
As more complicated realization, not only send synchronous clock by wired connection, also can send other wireless parameter by Wireline.For example, if by wired transmission radio communication address and security password, then any one telepilot can match with any one main frame, as long as connect and mutual wireless parameter by wired earlier, this has just increased dirigibility.
Be noted that in addition obviously, adopt above-mentioned clock synchronization mode after, the present invention obviously is not to use standard agreements such as bluetooth, but the self-designed wireless protocols of manufacturer.
Certainly, invention A is also not necessarily based on the frequency hopping communications technology.For example, also can adopt the used infrared communication technique of normal remote control in order to reduce cost.Infrared communication and without any need for the process of setting up wireless connections just need not send synchronous clock there being ray mode to issue in this case, because can be received the side of being received as long as send data.
In order to reduce,, can close wireless connections automatically, and this uses wired connection in case connected telepilot and main frame with the telepilot cable to the taking of wireless channel.
In invention A, can see the dump energy of each main frame at monitor terminal.Further, the present invention can watch the dump energy of each telepilot of each main frame at monitor terminal.Telepilot can be by wireless or have the bundle of lines dump energy to report to main frame, and main frame sends to monitor terminal by communication network with this information again and gets final product then.
Description of drawings
Accompanying drawing 1 is that telepilot is by synoptic diagram wired and that be wirelessly connected to main frame.
Embodiment
The key distinction of the present invention and invention A is that telepilot can be connected to main frame by the telepilot cable, and based on the various improvement of having derived of these characteristics, therefore narration hereinafter mainly concentrates on telepilot cable and the telepilot cable interface.
Invention A provide various expansion interfaces, for example USB, HDMI or the like.In fact the interface (hereinafter being called " telepilot cable interface ") of the connection telepilot cable that on the main frame (generally specifically is on the movement module of invention A) also can be considered as one of expansion interface.Can realize the wired connection of main frame and telepilot with various cable communicating technologies, for example USB, RS232 or the like.Every main frame of invention A can be equipped with a plurality of telepilots, correspondingly a plurality of telepilot cable interfaces can be set on main frame, and each interface can connect a telepilot.
For telepilot, should adopt rechargeable battery, and on the basis of invention A, add charging circuit.Simultaneously, telepilot should have the interface that is used to connect the telepilot cable, and this interface will mate with the remote controller interface of main frame, as USB, RS232.For example, the single-chip microcomputer in the telepilot is mixed the RS232 transceiver again and can be realized the RS232 interface.If perhaps the single-chip microcomputer in the telepilot has the USB device interface then can directly realize USB interface.
As seen, should comprise signal wire and power lead in the telepilot cable.Signal wire is according to the difference of the used communication technology and difference, and power lead then is used for charging.For example, the USB cable had just had power lead originally, therefore can directly use.RS232 then has only signal wire, if all use RS232, generally is with customized especially cable and interface, comprises signal wire and power lead simultaneously.In addition, promptly use USB, also not necessarily adopt the USB cable and the interface of standard, also can special voluntarily customized cable and interface, thus adapt to the environment (for example, promoting anti-destructive and wearing quality) in dining room.For another example, can with USB as mechanical interface, but the inside in fact usefulness be the signal of RS232.
All having detection telepilot cable on main frame (be meant particularly invention A movement module) and the telepilot is connected or the interlock circuit that disconnects, so when the telepilot cable connected upward or disconnects, main frame and telepilot can both detect this incident at once.Detection method is a lot, and for example whether the power lead of mechanical detection switch, the level that detects telepilot cable signal wire, detection telepilot cable is charged, or the like.Concrete detection method depends on telepilot cable and the data-signal form of specifically selecting for use.
