JP, 2005-341080, A

As in the system of Patent Document 1, for example, in a system in which a heating cooker can communicate with a data server via a repeater and a heating cooker can communicate with an external terminal, the heating cooker can communicate with the data server and the external terminal. When both are communicated in parallel at the same time, the heating cooker needs to perform signal processing at the same time, which increases the load on the control unit and the like. Therefore, it is necessary to enable communication with either the cooking device to the data server or the communication from the cooking device to the external terminal so as not to overlap with each other. Therefore, in order not to increase the load on the control unit of the heating cooker, it is conceivable to use a communication system in which communication destinations are switched without simultaneously communicating with both.

However, in the above communication system, for example, when the cooking device performs two-way communication with the data server (first data storage unit) and the operation data (first data) of the cooking device is transmitted and received by two-way communication. In order to communicate the control data (second data) between the heating cooker and the external terminal (second data storage unit), it is necessary to wait until the communication between the heating cooker and the data server is completed. It may take time to communicate between the heating cooker and the external terminal.

The present invention has been made in view of such circumstances, and shortens the time until the thermal device communicates with the second data storage unit without waiting for the completion of data transmission to the first data storage unit. It is an object of the present invention to provide a communication system capable of performing the communication.

A communication system of the present invention includes a thermal device, a first data storage unit that stores first data wirelessly communicated with the thermal device, and a second data storage that stores second data wirelessly communicated with the thermal device. And a second unit, wherein the first data is transmitted as a one-way signal from the thermal device toward the first data storage unit, and the second data is the thermal device and the thermal device. The thermal device is transmitted and received by performing bidirectional communication with the second data storage unit, and the thermal device transmits the second data rather than transmitting the first data to the first data storage unit. It is characterized in that bidirectional communication with the second data storage unit is prioritized.

In the present invention, the communication between the thermal device and the first data storage unit is transmission of a unidirectional signal from the thermal device to the first data storage unit. Therefore, in the thermal device, the first data storage unit transmits the signal. It is not necessary to confirm whether or not it is in a state in which it can be stopped, and transmission from the thermal device can be stopped. Accordingly, it is not necessary to wait until the communication between the thermal device and the first data storage unit is completed, and it is possible to quickly shift to the bidirectional communication between the thermal device and the second data storage unit. The time required to communicate with the storage unit can be shortened.

Further, it is preferable that the thermal device transmits the first data to the first data storage unit at predetermined intervals. Note that the transmission at a predetermined interval includes transmission at a constant interval (for example, every 3 seconds) and transmission at a non-constant interval (for example, 3 seconds, 5 seconds, 2 seconds).

According to the above configuration, since the first data is frequently transmitted from the thermal device to the first data storage unit multiple times, the thermal device may be transmitted during the transmission of the first data from the thermal device to the first data storage unit. Even if there is a communication request between the first data storage unit and the second data storage unit and transmission of the first data to the first data storage unit is stopped, or there is a transmission error of the first data to the first data storage unit, The first data storage unit can use the following first data, and the first data storage unit can reliably receive the first data from the thermal device.

Furthermore, it is preferable that the thermal device transmits the first data from the thermal device to the first data storage unit via a relay.

According to this configuration, by using the repeater, the first data can be transmitted from the thermal device to the repeater by using short-range communication such as Bluetooth (registered trademark), and the communication of the thermal device is required. Power consumption can be reduced.

Further, it is preferable that the first data is transmitted to the first data storage unit when there is a change in the first data.

According to this configuration, it is possible to reduce the load on the first data storage unit as compared with a case where all the first data is transmitted to the first data storage unit.

Furthermore, it is preferable that the first data includes time data to be received or transmitted.

With this configuration, it is not necessary to manage the time of the first data in the first data storage unit, and the load on the first data storage unit can be reduced.

Moreover, the said heat equipment is comprised with a heating cooker, the said 1st data are operation data containing at least the operation record or operation information of the said heating cooker, and the said 2nd data are the operation of the said heating cooker. It is preferably control data including instruction information.

According to this configuration, the operation instruction information of the heating cooker can be promptly transmitted without waiting for the completion of transmission of the operation data of the heating cooker. Accordingly, it is possible to change the heating power of the automatic cooking operation according to the operation instruction without a time delay, and it is possible to perform the automatic cooking according to the instruction without the failure of the automatic cooking operation.

In the present embodiment, the heating power of the first stove 10a can be changed to, for example, 11 steps, and the heating power of the second stove 10b can be changed to, for example, 9 steps, and the heating power 1 is the weakest. The fire power of 11 is the strongest.

Furthermore, a push-open type stove operating unit 12 and a grill operating unit 22 are provided on the front surface of the heating cooker 1. When the user P pushes and operates the stove operation unit 12, the stove operation unit 12 opens and the stove operation panel 13 appears. The stove operation panel 13 includes a first stove operation section 13a for the first stove 10a and a second stove operation section 13b for the second stove 10b. Similarly, when the user P pushes and operates the grill operating section 22, the grill operating section 22 opens and the grill operating panel 23 appears.

The stove operation panel 13 is configured so that the user P can perform operations related to the operation of the first stove 10a and the second stove 10b (for example, automatic cooking menu settings and timer time settings). It is configured to be able to display various information regarding the operation of the stove 10a and the second stove 10b. This also applies to the grill operation panel 23.

In addition to the above-described configuration, the heating cooker 1 further includes, as shown in FIG. 2, a control device 30 that controls the overall operation of the heating cooker 1, a speaker 26 that outputs a sound, and an external terminal 50. The communication device 27 for performing communication.

The control device 30 is composed of an electronic circuit unit including a CPU, a memory, an interface circuit and the like. The control device 30 may be composed of a plurality of electronic circuit units that can communicate with each other. Further, in the communication device 27 and the control device 30, even if the first stove 10a, the second stove 10b and the grill 20 are turned off, the power button 1a is kept in the on state and the communicable state is maintained.

The control device 30 includes detection signals of the temperature sensors 15a and 15b, operation signals of operation buttons (first and second stove operation buttons 11a and 11b, grill operation button 21), and an operation panel (stove operation panel). 13, the operation signal of the grill operation panel 23) and the signal received by the communication device 27 (the signal transmitted from the external terminal 50) are input.

The control device 30 controls the operation of each of the first stove 10a, the second stove 10b, and the grill 20 (i.e., ignition/fire extinguishing) by the function realized by executing the installed program or the function realized by the hardware configuration. Control), display control of the operation panel (the stove operation panel 13, the grill operation panel 23), output control of the speaker 26, and communication control with the external terminal 50 and the repeater 60 via the communication device 27. Is configured to get. For communication between the communication device 27 of the heating cooker 1 and the relay device 60, for example, short-distance communication such as Bluetooth (registered trademark) can be used. In this case, power consumption for communication can be reduced and power saving can be achieved. Become. Further, the heating cooker 1 is provided with a plurality of actuators such as a gas electromagnetic valve for controlling the flow of gas and a plurality of sensors such as an acceleration sensor for detecting vibration (none of which is shown). ..

Here, in the present embodiment, recipes for which the cooker 1 can obtain recipe data via the external terminal 50 are largely recipes for the first stove 10a and the second stove 10b and a recipe for the grill 20. Be separated.

The first stove 10a, the second stove 10b, and the grill 20 correspond to the heating unit in the present invention, but in the present embodiment, as an example, operation control when automatic cooking is performed using the first stove 10a. I will explain mainly.

The control device 30 has a function as a recipe data acquisition unit 32 that acquires recipe data corresponding to a recipe from the external terminal 50 by communicating with the external terminal 50 and a recipe data when executing cooking based on the recipe. It has a function as a recipe cooking execution processing unit 33 that controls the operation of the first stove 10a according to the automatic cooking data included in the corresponding recipe data (corresponding to the second data and the control data in the present invention). Although the automatic cooking data is well known and its detailed description will be simplified, for example, a plurality of blocks corresponding to respective operation controls such as combustion stop of the first stove 10a, reignition, and thermal power adjustment are provided. , Has a data structure in which a command signal for each operation control is recorded in each block. Then, the recipe data including the command signal for each operation control is transmitted by one transmission from the external terminal 50. Further, the block of operation control having no command signal is blank. It should be noted that the recipe data may include data of a recipe for preparation prepared by the user P.

The recipe data acquisition unit 32 of the control device 30 stores and holds the recipe data of the recipe acquired through communication with the external terminal 50 in a memory (not shown). In this case, in the present embodiment, the control device 30 can store and hold recipe data for each of a plurality (predetermined number) of recipes in the memory in response to an instruction from the user P by operating the external terminal 50. Is.

The recipe data stored and held in the memory can be appropriately updated or deleted by operating the heating cooker 1 or the external terminal 50.

In the present embodiment, the heating cooker 1 can execute, as a cooking mode using the first stove 10a and the second stove 10b, for example, a high-temperature stir-frying mode, a boiling water mode, a boiled dish mode, and a noodle boil mode. ing.

Each of the above modes is a well-known one, and the detailed description thereof will be simplified. However, the high-temperature frying mode is a mode in which cooking at a high temperature is possible, and the boiling water mode boil water to bring it to a boil. In this mode, the boiling state is maintained with a constant heating power after detection.

The boiled food mode is a mode in which water in which cooking ingredients are immersed is boiled, and the boiling state is maintained while switching the strength of the heating power after the detection of boiling, and the noodle boiled mode is after boiling the water. In this mode, when the noodles are dipped by the user P, the boiling state is maintained with a constant heating power after the boiling is detected.

Next, the flow of control of the communication system 5 will be described using the time chart shown in FIG.

As shown in FIG. 3, the user P operates the power button 1a to turn on the power of the heating cooker 1 (time: t0). Then, the user P operates the first stove operation button 11a to ignite the first stove 10a, and cooks using the first stove 10a. Cooking here is cooking different from automatic cooking which will be described later in detail. It should be noted that the first stove 10a is extinguished before automatic cooking described later in detail.

When the power of the cooking device 1 is turned on (time: t0), the cooking device 1 and the external terminal 50 perform two-way communication, which is a pair of communication including a command signal and an answer signal, which will be described later in detail. In a non-executed state, the operation data indicating the operation record or the operation information of the heating cooker 1 is relayed as a one-way signal from the heating cooker 1 to the relay 60 every predetermined time (for example, 3 seconds). To the container 60 (time: t1 to t3, t9, t10). Note that FIG. 3 illustrates a form in which the operation data is simply transmitted 5 times. Also, the operation data may be transmitted at irregular intervals (for example, 3 seconds, 5 seconds, 2 seconds, etc.).

Further, when the cooking device 1 and the external terminal 50 are bidirectionally communicating with each other at the timing of transmitting operation data every 3 seconds, the cooking device 1 and the external terminal 50 communicate with each other. After the two-way communication ends, the operation data is transmitted to the relay 60 as a one-way signal from the heating cooker 1 to the relay 60.

Further, in the present embodiment, when there is a communication request for two-way communication between the heating cooker 1 and the external terminal 50 during the transmission of the operation data from the heating cooker 1 to the relay device 60, the heating is performed. The transmission of the operation data from the cooking device 1 to the relay device 60 is stopped, and the heating cooking device 1 and the external terminal 50 are preferentially bidirectionally communicated. Therefore, the recipe data can be promptly transmitted from the external terminal 50 to the heating cooker 1 without a time delay without waiting for completion of transmission of the operation data from the heating cooker 1 to the relay 60. Accordingly, it is possible to change the heating power of the automatic cooking operation according to the operation instruction without a time delay, and it is possible to perform the automatic cooking according to the instruction without the failure of the automatic cooking operation.

In the present embodiment, the heating cooker 1 repeats at every 3 seconds (intermittently) in a state where the two-way communication, which is a pair of communication consisting of a command signal and an answer signal, is not performed with the external terminal 50. Since the operation data is transmitted to 60, even when there is a communication request between the heating cooker 1 and the external terminal 50 during the transmission of the operation data and the transmission of the operation data from the heating cooker 1 to the relay device 60 is stopped. The operation data can be transmitted after the two-way communication between the heating cooker 1 and the external terminal 50 is completed. Thereby, the operation data can be reliably transmitted to the repeater 60.

In addition, when there is a communication request between the heating cooker 1 and the external terminal 50 during transmission of the operating data from the heating cooker 1 to the relay 60, the operating data from the heating cooker 1 to the relay 60 is transmitted. Transmission may be stopped, and the operation data for which the transmission has been stopped may be transmitted again after the two-way communication between the heating cooker 1 and the external terminal 50 is completed, and this transmission is not performed again. May be.

In the time chart shown in FIG. 3, the horizontal axis is the time (time) axis, and the first axis L1 indicating the time elapse of the heating cooker 1, the second axis L2 indicating the time elapse of the external terminal 50, and the repeater 60. The horizontal axis indicates the third axis L3 indicating the passage of time and the fourth axis L4 indicating the passage of time of the data server 70. The vertical axis with an arrow indicates transmission/reception of signals between the heating cooker 1 and the external terminal 50 or the relay 60, and transmission/reception of signals between the relay 60 and the data server 70.

When the operation data is transmitted from the heating cooker 1 to the repeater 60 (time: t1 to t3, t9, t10), the heating cooker 1 operates from the start of the operation data transmission to the completion of the operation data transmission. , Operation data is transmitted to the relay 60 as a one-way signal from the heating cooker 1 to the relay 60.

The operation data includes, for example, power supply state data (on/off), operation state data (stop, error stop, operation completion stop, running), thermal power data (1 to 11), temperature data detected by the temperature sensors 15a and 15b. , Cooking mode (high temperature stir mode, boiling water mode, boiled food mode, noodle boil mode), error code. The error code is, for example, a two-character code preset according to the model of the heating cooker 1. The temperature data is, for example, data for every 10°C. The operation data is not limited to the above data, and can be changed as appropriate.

When receiving the operation data, the repeater 60 compares the operation data with the operation data received immediately before, for example, and determines whether or not the operation data has changed. When the operation data changes (for example, the heat power changes) during cooking by the first stove 10a (time: t2), the relay device 60 adds the received time data (time stamp) to the operation data. After that, the operation data is transmitted to the operation data storage unit 70b of the data server 70. The repeater 60 does not transmit the unchanged operation data to the operation data storage unit 70b of the data server 70 (time: t1, t3, t9, t10). Further, the relay device 60 may add the time data (time stamp) to be transmitted to the operation data and then transmit the operation data to the operation data storage unit 70b of the data server 70. Further, the operation data may be transmitted to the relay device 60 after adding the time data (time stamp) transmitted by the heating cooker 1.

The operation data storage unit 70b of the data server 70 stores the received operation data. This data is transmitted to, for example, the manufacturer of the heating cooker 1 and used for checking the state of the heating cooker 1.

In the present embodiment, the repeater 60 transmits the operation data to the operation data storage unit 70b of the data server 70 when the received operation data changes, so that all the operation data is stored in the operation data of the data server 70. It is possible to reduce the load on the operation data storage unit 70b of the data server 70 as compared with the case of transmitting to the unit 70b.

Further, the relay device 60 adds the reception time data to the operation data and transmits the operation data to the operation data storage unit 70b of the data server 70, so that the operation data storage unit 70b of the data server 70 does not need to perform time management of the operation data. The load on the operation data storage unit 70b of the data server 70 can be reduced.

Here, a pre-process performed before making a communication request for performing automatic cooking from the external terminal 50 will be described.

When performing automatic cooking with the heating cooker 1, the user P operates the touch panel 51 of the external terminal 50 to execute the automatic cooking application. When the automatic cooking application is executed, a plurality of recipes (dish names) are displayed on the touch panel, and the user P selects the desired recipe.

The external terminal 50 acquires the recipe data of the recipe selected by the user P from the cooking data storage unit 70a of the data server 70 via the Internet. Then, the external terminal 50 puts a recipe for preparation included in the acquired recipe data (for example, a predetermined amount of ingredients such as vegetables and meat, a predetermined amount of water, and a predetermined amount of seasoning into a cooking container such as a pan). Insert) is displayed on the touch panel 51. The user P makes a preparation according to the preparation recipe displayed on the touch panel 51.

When the user P finishes the preparation, the user P places the cooking container on the first stove 10a. After placing the prepared cooking container on the first stove 10a, the user P operates the touch panel 51 of the external terminal 50 to request the heating cooker 1 to perform a communication request for automatic cooking. Perform (time: t4).

When the communication request for automatic cooking is made from the external terminal 50 (time: t4), the heating cooker 1 transmits an answer signal indicating that the external terminal 50 is permitted to communicate (time: t4). : T5). The communication request is to transmit a communication request signal from the external terminal 50 to the heating cooker 1. The external terminal 50 determines, based on the answer signal, that bidirectional communication is possible and automatic cooking is possible. In the present embodiment, the bidirectional communication is a pair of communication including a request signal (command signal) and an answer signal.

When a communication request for performing automatic cooking is made from the external terminal 50 and the heating cooker 1 and the external terminal 50 are preferentially bidirectionally communicated with each other, the heating cooker 1 and the relay device 60 perform bidirectional communication. In this case, it is necessary to wait until the communication between the heating cooker 1 and the relay 60 is completed, which may take time.

In the present embodiment, the operation data is transmitted to the repeater 60 as a one-way signal from the heating cooker 1 to the repeater 60. Therefore, is it a state in which the repeater 60 may stop the transmission? It is possible to stop the transmission from the heating cooker 1 to the relay device 60 and to preferentially cause the heating cooker 1 and the external terminal 50 to perform two-way communication without confirming. As a result, the time until the above-described priority control is performed and the bidirectional communication between the heating cooker 1 and the external terminal 50 is performed as compared with the case where it is necessary to wait until the communication between the heating cooker 1 and the relay 60 is completed. Can be shortened.

The heating cooker 1 transmits an answer signal to the external terminal 50 (time: t5). The external terminal 50 transmits recipe data of the recipe selected by the user P (for example, step A: boiling water mode 10 minutes, step B: boiled food mode 30 minutes, step C: fire extinguishing) to the cooking device 1 ( Time: t6). The recipe data also includes thermal power data in each mode.

When the cooking device 1 receives the recipe data from the external terminal 50, the cooking device 1 transmits an answer signal indicating the reception to the external terminal (time: t7).

After receiving the recipe data in the heating cooker 1, the user P operates the first stove operation button 11a to ignite the first stove 10a (time: t8). When the first stove 10a is ignited, the control device 30 (recipe cooking execution processing unit 33) of the heating cooker 1 starts automatic cooking based on the received recipe data (steps A to C).

The heating cooker 1 transmits operation data indicating the operation state of the first stove 10a to the relay 60 every 3 seconds even during automatic cooking (time: t9, t10).

Further, although not shown, when the cooker 1 receives the recipe data (time: t6), an operation indicating an operating state of the cooker 1 (for example, automatic cooking start, automatic cooking in progress, automatic cooking end, etc.). The state data (corresponding to the second data and the control data in the present invention) may be bidirectionally communicated with the external terminal 50. As a result, the external terminal 50 displays the received operating state data on the touch panel 51, and the user P can confirm the operating state data displayed on the touch panel 51 and know the operating state of the heating cooker 1. it can. In addition, when the external terminal 50 receives the operation state data from the heating cooker 1, the external terminal 50 transmits an answer signal indicating the reception to the heating cooker 1.

In the present embodiment, even when the operating state data is transmitted, the heating cooker 1 and the external terminal 50 are transmitted from the heating cooker 1 to the operation data storage unit 70b via the relay 60, rather than transmitting the operating data. Priority control is performed so that bidirectional communication is prioritized. Thereby, the operation state data can be quickly transmitted to the external terminal 50.

The timing at which the data of the operating state of the heating cooker 1 is transmitted from the heating cooker 1 to the external terminal 50 is a period from the receipt of the recipe data to the end of automatic cooking (time: t11) described later in detail. It can be changed as long as it is within the range, and for example, it may be transmitted at every predetermined time.

When performing automatic cooking according to the received recipe data, the recipe cooking execution processing unit 33 first sets the first cooking stove 10a in the boiling water mode (for example, the heating power of the first cooking stove 10a is 5 in 11 steps) in step A. Control to operate for 10 minutes.

Next, the recipe cooking execution processing unit 33 operates in the boiling water mode for 10 minutes, and then, in Step B, in the boiling mode (for example, switching the heating power of the first stove 10a between 7 and 3 of 11 steps) 30 Control to operate for minutes.

Then, the recipe cooking execution processing unit 33 operates in the boiled food mode for 30 minutes, and then, at step C, controls the operation of the first stove 10a so as to extinguish the fire. When the above steps A to C are performed, the automatic cooking ends (time: t11).

After the user finishes the automatic cooking, when the user P operates the power button 1a to turn off the power of the heating cooker 1 (time: t12), the control by the communication system 5 ends.

Next, the flow of control of the communication system 5 will be described using the flowchart shown in FIG.

As shown in FIG. 4, when the user P operates the power button 1a to turn on the power of the cooking device 1, the cooking device 1 is not in bidirectional communication with the external terminal 50 (STEP 7 described later). In "YES", the operation data is transmitted to the repeater 60 every 3 seconds (STEP 1).

When there is a change in the received operation data (for example, a change in thermal power) (“YES” in STEP 2), the relay device 60 adds the received time data (time stamp) to the operation data, and then adds the operation data. Is transmitted to the operation data storage unit 70b of the data server 70 (STEP 3). Note that the relay device 60 does not transmit the operation data to the operation data storage unit 70b of the data server 70 when there is no change in the operation data (“NO” in STEP2).

The heating cooker 1 performs STEP 1 again when 3 seconds have elapsed since the operation data was transmitted to the relay device 60 (STEP 1) (“YES” in STEP 4 ).

After placing the cooking container on the first stove 10a, the user P makes a communication request from the external terminal 50 to the heating cooker 1 to perform automatic cooking.

3 seconds have not passed since the operation data was transmitted to the repeater 60 (STEP 1) (“NO” in STEP 4), and the external cooker 1 sends a communication request for automatic cooking to the cooking device 1. When the answer signal is transmitted from the heating cooker 1 to the external terminal 50 ("YES" in STEP 5), the heating cooker 1 and the external terminal 50 are in a state capable of bidirectional communication (STEP 6).
