Technical Field

[0001] The automatic cooking technology of a robot that can be controlled by a mobile phone according to the present invention relates to the fields of artificial intelligence and cooking. Background Art

[0002] Robot cooking, also known as an automatic stir-fry machine or an intelligent stir-fry machine. In today's society, with the development of the robot cooking industry, robot cooking is getting closer and closer to our lives. In addition to various household robot cooking, many commercial robot cooking technologies have been applied in many places such as restaurants, factories, schools, and government agencies. Correspondingly, the related products and technologies of commercial robot cooking are also changing with each passing day. Brands visible in the market include "Aofengchen", "Haoshite", "Semikron", "Lingmeng", "Dazhangshao", "Maidachu", "Yinghaida", "Deliloc", "Semicon", "Chineng", "Discoverer", "Mengde", "Aofengda", "Gongying", and so on.

[0003] Analysis shows that there is no function of automatically controlling robot cooking through a mobile phone in existing commercial cooking robots and related technologies retrieved by patents. Existing commercial cooking robots basically cook by manually operating buttons. In particular, there is no technology for automatically controlling multiple commercial cooking robots with a mobile phone. Therefore, the present invention is proposed to meet the needs of the future development of commercial robot cooking automation. Summary of the Invention

[0004] The object of the present invention is to provide a technology on the basis of existing commercial cooking robots that can be operated through a mobile phone app and automatically control one or more commercial cooking robots to cook according to human instructions.

[0005] To achieve the above object, the structure of the automatic cooking technology of a robot that can be controlled by a mobile phone according to the present invention includes an ordering QR code, a 4G cloud printer, a signal recognition and conversion module group, an intermediate relay, and a PLC.

[0006] Furthermore, the order-taking QR code used is the general order-taking QR code in the catering industry on the market. The present invention uses the order-taking QR code provided by the "WowPay Payment Platform". This order-taking QR code can receive any mobile phone for scanning and ordering without registration.

[0007] Furthermore, the 4G cloud printer used is also the general printer in the catering industry. The present invention uses the 58 thermal 4G cloud printer, model CB2, provided by the "WowPay Payment Platform". This printer has its own network and can be used for printing in many occasions.

[0008] Furthermore, the signal recognition and conversion module group is composed of two general-purpose voltage conversion and boost modules on the market. One is the AD620 high-precision microvolt to millivolt voltage amplifier module, which is powered by a 12V DC power supply and can convert the weak voltage of the thermal printer into a voltage of about 10V. The other is the voltage boost and amplification module. Optional brands include "Shantou Lin Cun", "YEYY Yueyu", and "Yu Qin". The present invention selects the "Shantou Lin Cun" brand voltage boost and amplification module, which is powered by a 24V DC power supply and can boost the low voltage of 0V - 10V to 24V. The connection method of the above two modules is as follows: Connect the positive and negative two wires of the signal output end of the AD620 module to the positive and negative signal input ends of the voltage boost and amplification module. The AD620 module is powered by 12V, and the voltage boost and amplification module is powered by 24V. The two modules form a set of signal modules (see attached Figure 1 ).

[0009] Furthermore, the intermediate relay used is a general-purpose base-mounted DC 24V eight-pin electromagnetic relay on the market, with two normally open points, two normally closed points, two common points, and two power supply terminals. The present invention uses the "IDEC" brand intermediate relay, model RJ2S-CL(DC24V). This electromagnetic relay is composed of an iron core, a coil, an armature, contact reeds, etc. Usually, when the relay is powered, a certain current flows through the relay coil, thus generating an electromagnetic effect. The armature inside the relay will be attracted by the electromagnetic force and overcome the pulling force of the return spring to be attracted to the iron core, thereby driving the moving contact of the armature to engage with the normally open static contact, and the normally open point circuit is conducted. After the relay power supply is interrupted, the electromagnetic attraction of the coil also disappears, and the armature will return to its original position under the reaction force of the spring, causing the moving contact to engage with the normally closed contact, and the normally closed point circuit is conducted.

[0010] Furthermore, the PLC is the operation control host for the commercial cooking robot and the relay actuator. The present invention uses the Delta brand PLC, model DVP-16XN.

[0011] The structural connection relationships of the above meal-ordering QR code, 4G cloud printer, signal recognition and conversion module, relay, and PLC are as follows: Two wires are welded and led out from the printing wire on the printer head in the above thermal printer and connected to the signal input end of the AD620 module. The positive and negative poles of the 12V DC power supply are respectively connected to the power supply end of the AD620 module. Then, the two wires at the signal output end of the AD620 module are connected to the signal input end of the voltage boost and amplification module. The power supply end of the voltage boost and amplification module is connected to the positive and negative poles of the 24V DC power supply. The positive and negative signals at the two output ends of the voltage boost and amplification module are connected to the power supply end of the intermediate relay. The normally open point and the common terminal of the intermediate relay are then connected to the PLC input end. The cooking start button and stop button circuits of the commercial cooking robot are connected through the PLC output end (see appendix Figure 2 ).

[0012] Furthermore, in the present invention, different cooking information is respectively converted into different voltage signals that can be recognized by the relay. The 4G cloud printer also needs to be designed in the background: The manager sets the printer as a separate kitchen order in the printer settings of the "Wosai Payment Platform" for the store merchant, and specifies that the printer only prints a certain dish (one dish is cooked by one commercial cooking robot). In this way, for each commercial cooking robot (each cooking one dish), the corresponding number of printers and signal recognition and conversion module groups are configured. One signal recognition and conversion module group is connected to one intermediate relay, and one relay is connected to one commercial cooking robot.

[0013] The technical solution adopted by the present invention is as follows: When it is necessary to start a certain commercial cooking robot for cooking, scan the QR code on the QR code sign through the mobile phone app, and then select the desired cooking dish on the popped-up dish selection screen. After the payment is completed (the price can be set to 0.1 yuan each time, only for control), the corresponding 4G cloud printer starts to print the menu. The signal recognition and conversion module group connected to the printer will convert the signal of the printer into a 24V voltage signal. The intermediate relay connected to the output end of the signal recognition and conversion module group receives the 24V voltage signal of the signal recognition and conversion module group, causing the power supply end of the relay to be energized. The common terminal and the normally open point of the relay are connected, and the PLC input end receives the connection signal of the intermediate relay and will connect the cooking start button circuit of the commercial cooking robot through the PLC output end, and the commercial cooking robot starts cooking. The cooking time of the commercial cooking robot is controlled by the PLC and is set in advance according to the cooking time required for the dish. When the set cooking time ends, the PLC will disconnect the power supply of the relay, and the normally open point and the common terminal of the relay will be disconnected, and the commercial cooking robot will stop cooking (see appendix Figure 3 ).

Detailed Embodiment

[0020] The following specifically describes the preferred implementation manner of the technical solution of the present invention with reference to the drawings.

[0021] The purpose of the present invention is to provide a technology that can operate through a mobile phone app and automatically control one or more commercial cooking robots to cook according to human instructions.

[0022] In order to achieve this purpose, the preferred implementation of the present invention is realized by ordering QR code, 4G cloud printer, signal recognition and conversion module group, intermediate relay and PLC. The preferred QR code for ordering food is the QR code for ordering food provided by the "Oh Tai Shou Qian Bar" platform, the 4G cloud printer is a 4G cloud printer with a network 58 thermal printer, and the signal recognition and conversion module group is according to the attached Figure 1 The two connected modules (AD620 high-precision microvolt and millivolt voltage amplifier module and "Shantou Lincun" brand voltage boost amplifier module), the intermediate relay is the "Hequan" brand eight-pin relay, and the PLC model is AS228T-A Delta brand PLC. The various parts are connected according to the attached Figure 2 Connect and control the start button and stop button power line of the commercial cooking robot through the PLC output end.

[0023] The preferred implementation method also requires further background design: the commercial cooking robot manager needs to set the printer as a cooking order in the printer settings of the store merchant management on the "Oh Tai Shou Qian Bar" platform, and specify that the printer only prints a certain dish (one dish is cooked by one commercial cooking robot). In this way, as many printers and signal recognition and conversion module groups as there are commercial cooking robots (each of which can cook one dish), one signal recognition and conversion module group is connected to a relay, and one relay is connected to one commercial cooking robot.

[0024] The specific preferred implementation is as follows: Figure 3As shown in the figure, disconnect the positive power supply lines of the start buttons of the five "Semicon" commercial cooking robots labeled A, B, C, D, and E (control the positive but not the negative), and connect the two disconnected lines to the five output terminals (on and off) of the PLC. Connect the five input terminals of the PLC to the normally open contacts and common terminals of five relays respectively. Then connect the positive and negative power supply terminals of the five relays to the signal output terminals of the aforementioned five groups of signal recognition and conversion module groups, and connect the signal input terminals of the five groups of signal recognition and conversion module groups to the two signal lines welded from five 4G cloud printers. When it is necessary to start a certain commercial cooking robot for cooking, for example, select the commercial cooking robot labeled D to cook stir-fried pork with green peppers. Scan the code on the code scanning plate through the mobile phone app, then select the corresponding stir-fried pork with green peppers in the popped-up dish selection screen, and make a payment (the price can be set arbitrarily, only for control). The 4G cloud printer corresponding to the D commercial cooking robot starts to print the menu. While the printer is printing the menu, the printer will output a 1-5V voltage signal. The signal recognition and conversion module group corresponding to this printer will convert the signal of the printer into a 24V voltage signal. The corresponding intermediate relay receives the 24V voltage signal from the recognition and conversion module, causing the power supply terminal of the relay to be energized. The common terminal of the relay is connected to the normally open contact, and the PLC input terminal connected to the normally open contact and common terminal connection signal of the intermediate relay will start the conduction of the start button circuit corresponding to the D commercial cooking robot at the output terminal, and the D commercial cooking robot starts cooking. The cooking time of the D commercial cooking robot is controlled by the PLC and is set in advance according to the cooking time required for the dish. When the set cooking time ends, the PLC will disconnect the D output terminal, and the commercial cooking robot will stop cooking.
