  The food processing data composed of the temperature measurement data of the temperature sensors 9a, 9b, 10a, 10b and the cooking time data of the cooking time timer 10c and the energy consumption data measured by the power meter 8 are obtained from the network controller 13 by, for example, LonWorks ( The data is periodically transmitted to the management server 17 connected to the Internet 16 via the open network 14 such as a registered trademark) at a set time set in a relatively short time such as 1 minute. In addition, the management server 17 sends a power-saving command to the air conditioning device controller 11 that controls the air conditioning device 5 and the lighting device controller 12 that controls the lighting device 6 via the Internet 16, the gateway 15, and the open network 14 as necessary. The air conditioner controller 11 controls the set temperature of the air conditioner 5 based on the received power-saving command, and the lighting device controller 12 controls the lighting device 6 based on the received power-saving command.

The management server 17 analyzes the food processing data and the energy consumption data transmitted from the food processing facility 1 to determine whether or not it is necessary to perform energy saving control and power peak cut control, and based on this determination result. Take energy-saving control measures or execute peak cut control when the power peak is exceeded.
That is, the management server 17 collects food processing data and energy consumption data that are regularly transmitted from the product processing facility 1 and stores them in a storage device such as a hard disk, for example, for each day. Based on the data, the hygiene management process shown in FIG. 2, the analysis process shown in FIG. 3, and the energy management process shown in FIG. 4 are executed.

  As shown in FIG. 2, in the hygiene management process, first, in step S1, refrigeration temperature data, frozen temperature data, frozen cooking temperature data, and cooking time data as food processing data transmitted from the food lowering facility 1 as needed are read. Then, the process proceeds to step S2, where it is determined whether the refrigeration temperature data satisfies HACCP (Hazard Analysis and Critical Control Point) regulations, and the refrigeration temperature data satisfies the HACCP regulations. If not, the process proceeds to step S3, a temperature control command is transmitted to the commercial refrigerator 2 so that the refrigeration temperature data satisfies the HACCP regulation, and then the process proceeds to step S4, where the refrigeration temperature data is the HACCP regulation. If satisfied, the process directly goes to step S4.

  In this step S4, it is determined whether or not the refrigeration temperature data satisfies the HACCP regulation. When the refrigeration temperature data does not satisfy the HACCP regulation, the process proceeds to step S5, and the freezing temperature for the commercial freezer 3 is determined. After the temperature control command is transmitted to the commercial freezer 3 so that the data satisfies the HACCP regulations, the process proceeds to step S6, and when the refrigeration temperature data satisfies the HACCP regulations, the process proceeds directly to step S6.

  In this step S6, it is determined whether or not the bottom surface temperature data and the food core temperature data of the cooking devices 4A to 4C satisfy the HACCP regulations, and both processing cooking devices 4i (i = A to C) If any of the temperature data does not satisfy the HACCP specification, the process proceeds to step S7, and a temperature control command is issued to the cooking device 4i (i = A to C) so as to satisfy the temperature satisfying the HACCP specification. After the transmission, the process proceeds to step S8, and when the bottom surface temperature data and the food core temperature data satisfy the HACCP regulations for all the processing cooking appliances 4A to 4C, the process directly proceeds to step S8.

  In this step S8, it is determined whether or not the cooking time data of each of the heating cooking appliances 4A to 4C satisfies the HACCP regulations, and when the cooking time data does not satisfy the HACCP regulations, the process proceeds to step S9. When a cooking time change command is transmitted to the cooking device 4j (j = A to C), the process returns to step S1, and when the cooking time data satisfies the HACCP regulations in all the cooking devices 4A to 4C Return directly to step S1.

  The analysis process is executed when desired. First, in step S11, the food processing data and energy consumption data transmitted from the food processing facility 1 for the most recent day stored in the storage device are read, and then the step is performed. The process proceeds to S12 to create a time chart such as a line graph in which the read food processing data and energy consumption data can be compared with each other at the same time, and then the process proceeds to step S13 to create the processed food processing data and Display data including a time chart of energy consumption data is formed, and then the process proceeds to step S14, and the formed display data is displayed on the display 18, and then the process proceeds to step S15.

  In this step S15, it is determined whether or not the analysis process is to be terminated. When the analysis process is terminated, the analysis process is terminated as it is. When the analysis process is not terminated, the process proceeds to step S16, and data for another one day is obtained. When it is determined whether or not to perform analysis, and when data analysis for another day is not performed, the process returns to step S14 to continue the display process, and when data analysis for another day is performed, The process proceeds to S17, where it is determined whether or not the month / day to be analyzed is input from the keyboard 19. If the month / day input is not completed, the process waits until the month / day input is completed. The process proceeds to S18, and after reading the food processing data and energy consumption data of the corresponding month stored in the storage device, the process proceeds to Step S12.

The analysis process of FIG. 3 corresponds to the analysis means.
As shown in FIG. 3, in the energy management process, first, in step S21, the energy consumption data WD periodically input from the food processing facility 1 to be managed that is sequentially input is read, and then in step S22. It is determined whether or not the read energy consumption data WD is equal to or higher than a preset peak setting value PD for starting the preset peak cut control. When WD <PD, it is not necessary to perform the peak cut control. The process proceeds to step S30, which will be described later. If WD ≧ PD, it is determined that peak cut control needs to be performed, and the process proceeds to step S23.

  In step S23, first, a transmission request for instructing transmission of a state signal indicating whether the air conditioner is in a heating state or a cooling state and the current set temperature is transmitted to the air conditioner 5, and then the step is performed. The process proceeds to S24 to determine whether or not the status signal and the set temperature are received. When the status signal and the set temperature are not received, the process waits until they are received, and when the status signal and the set temperature are received, The process proceeds to step S25 to determine whether or not the set temperature is the allowable maximum temperature. When the set temperature has not reached the allowable maximum temperature, the process proceeds to step S26, and when the set temperature is being cooled, the set temperature is increased by 1 ° C. When heating is in progress, a power saving command for lowering the temperature by 1 ° C. is transmitted to the air conditioner 5, and then the process proceeds to step S <b> 27, and a predetermined time necessary for the power saving effect appears. To determine Taka not, when not in a predetermined time elapses waits until it has passed, the flow returns to the step S21 when a predetermined time has elapsed.

  If the determination result in step S25 indicates that the set temperature has reached the allowable maximum temperature, the process proceeds to step S28, and a power saving command is issued to the lighting device 6 to perform the extinguishing control of the lighting equipment that can be turned off in advance. After output, the process proceeds to step S29, where it is determined whether or not a predetermined time required for the power saving effect to appear. If the predetermined time has not elapsed, the process waits until the predetermined time elapses. When elapses, the process returns to step S21.

  When the determination result of step S22 is that the energy consumption data WD is less than the peak value PD, the process proceeds to step S30 to determine whether or not the power saving control is being performed on the lighting device 6, and the power saving control is being performed. In some cases, a power saving cancellation command for canceling the power saving control is transmitted to the lighting device 6, and then the process proceeds to step S <b> 31 to determine whether a predetermined time required for the lighting device 6 to achieve the power saving cancellation effect has elapsed. If the predetermined time has not elapsed, the process waits until the predetermined time elapses, and returns to step S21 when the predetermined time elapses.

If the determination result in step S30 is not during the power saving control for the lighting device 6, the process proceeds to step S33 to determine whether the power saving control for the air conditioner 5 is being performed. If not, the process returns to step S21. If the power saving control is being performed, the process proceeds to step S34, a temperature return command for returning the set temperature to 1 ° C. is transmitted to the air conditioner 5, and then the process proceeds to step S35. It is determined whether or not a predetermined time required for the power saving cancellation effect of the machine device 5 to appear. If the predetermined time has not elapsed, the process waits until the predetermined time has elapsed. Return to S21.
The energy consumption management process of FIG. 3 corresponds to the energy consumption management means.

Next, the operation of the above embodiment will be described.
First, in order to analyze the operating state of the food processing facility 1, first, analysis processing is executed by the management server 17, and the food processing data and energy consumption data for the most recent day stored in the storage device are read ( Step S1) After creating a time chart of each food processing data and energy consumption data (Step S12), display data including both is created (Step S13), and the created display data is displayed on the display 18. Thus, the cooking status and the energy consumption status of the food processing data are displayed on the same display screen. For this reason, by visually recognizing the displayed cooking status and the energy consumption status, a wasteful operating state of the cooking devices 4A to 4C has occurred, or by adjusting the cooking time of the cooking devices 4A to 4C, It is possible to accurately analyze that it is possible to exert an energy saving effect. By performing this analysis for different desired dates, it is possible to optimize the cooking times of the cooking devices 4A to 4C so as to maximize the energy saving effect.

  On the other hand, when the food processing facility 1 is in a normal operating state, the food hygiene management process of FIG. 2 is executed, and the temperatures of the commercial refrigerator 2 and the commercial freezer 3 are controlled so as to satisfy the HACCP regulations. Along with (Steps S2 to S5), the cooking temperature and cooking time of the cooking devices 4A to 4C are controlled so as to satisfy the HACCP regulations (Steps S6 to S9).

  In the energy consumption control process of FIG. 4, the energy consumption data WD transmitted from the power meter 8 is read (step S21), and it is determined whether or not the read energy consumption data WD is greater than or equal to the peak set value PD. However, if WD <PD, it is determined that the energy consumption is not excessive. If the power saving control is not being performed for the air conditioner 5 and the lighting device 6, the process goes through steps S30 and S33 to step S21. When the energy consumption WD becomes equal to or greater than the peak set value PD, a state signal indicating whether the air conditioner 5 is in the cooling state or the heating state and a transmission request for the current set temperature are transmitted (step S23). ) When the status signal and the set temperature are received, it is determined whether or not the current set temperature has reached the maximum allowable temperature. When the temperature has not been reached, it is determined that the energy saving effect by the temperature control of the air conditioner 5 can be exerted, and the process proceeds to step S26, where the set temperature is increased once by the air conditioner 5 during cooling. Then, after transmitting a power saving command for lowering once during heating, the process returns to step S21 after waiting for a predetermined time when the power saving effect appears. For this reason, when the set temperature of the air conditioner 5 is changed by 1 ° C., the power consumption is reduced by this amount, and the peak cut control of the energy consumption can be performed.

  At this time, when the energy consumption data WD falls below the peak set value PD, the process proceeds from step S22 to step S30, and the power saving control is not performed on the lighting device 6, so the process proceeds to step S33, and the air conditioning equipment 5 is under power saving control, the process proceeds to step S34, a temperature return command is transmitted to the air conditioner 5, and the set temperature of the air conditioner 5 is returned to the previous state, that is, the set temperature. In this state, after waiting for a predetermined time, the process returns to step S21.

  However, even if the temperature of the air conditioner 5 is changed by 1 ° C., when the energy consumption data continues to be equal to or higher than the peak set value PD, the process proceeds to step S26 again, and the set temperature of the air conditioner 5 is further set to 1. A power saving command for changing the temperature is transmitted to change the set temperature of the air conditioner 5 in the power saving direction. During this time, when the energy consumption data WD becomes less than the peak set value PD, the set temperature of the air conditioner 5 is changed to return to the preset set temperature.

  However, when the maximum allowable temperature is reached when the set temperature of the air conditioner 5 is changed, no further power saving effect can be exhibited. A power-saving command for controlling turning off lighting devices set in advance is transmitted, energy-saving control of the lighting device 6 is performed, and peak cut control for reducing energy consumption is performed. Thereafter, energy consumption of the cooking devices 4A to 4C When the energy consumption data WD becomes less than the peak set value PD due to the decrease in energy consumption, the energy saving control of the lighting device 6 is canceled accordingly, and even in this state, the energy consumption data WD is less than the peak set value PD. In some cases, the set temperature of the air conditioner is sequentially returned to the first set temperature to return to the normal operating state.

  As described above, according to the above-described embodiment, the food processing data is collected, and based on this, the food hygiene management process for managing whether or not the food processing process satisfying the HACCP regulations is performed is executed. At the same time, the energy consumption data supplied to the food processing facility 1 is also collected, so that the food processing facility is optimally operated to save energy by comparing the food processing data with the energy consumption data. It is possible to search for the situation. For this reason, it becomes possible to perform an energy saving operation by adjusting the cooking time of the cooking devices 4A to 4C, and an optimum energy saving operation state in the entire food processing facility 1 can be set.

  Moreover, the management server 17 can control the commercial refrigerator 2, the commercial freezer 3, and the cooking devices 4A to 4C so as to satisfy the HACCP regulations and perform accurate food hygiene management, and energy saving control. By comparing the energy consumption data WD and the peak set value PD in the processing, the food processing is not directly affected when the energy consumption data WD becomes an excessive energy consumption state exceeding the peak set value PD. It is possible to optimize energy consumption by executing peak cut control for controlling the energy consumption to be reduced by setting the air conditioner 5 and / or the lighting device 6 in the power saving control state.

The measurement unit MU1 is configured to transmit the temperature data and the operation state data measured at the temperature measurement terminal 23 and the operation state monitoring terminal 24 to the data storage unit AU at a preset time interval, for example, one minute interval. Similarly, the measurement unit MU1 transmits the interphase voltage and phase current measured at a preset time interval, for example, 1 minute interval, as energy consumption data to the data storage unit AU. In addition, as an operation state measured by the operation state monitoring terminal 24, in addition to measuring an on / off operation state, a state can be acquired for each of a plurality of operation modes.

Referring to the status data, if it is in a non-operating state, the corresponding food data is set to be discarded without being stored, and the food processing data is stored in the storage device only when the managed device is in the operating state. By doing so, it is not necessary to store all of the enormous amount of measurement data transmitted every relatively short time, such as every minute, so that the storage amount in the storage device can be greatly reduced. In addition, since analysis processing and energy consumption management processing can be performed based on measurement data every short period of time, such as every minute, it is possible to perform high-resolution, detailed and accurate processing.

  In addition, in the said 2nd Embodiment, although the case where only temperature data was measured as food processing data was demonstrated, it is not limited to this, About cooking time data, cooking start time and cooking end time are By forming a node that transmits cooking start time data and cooking end time data at the timing when these are input, the cooking server also manages cooking time data even for devices that are not compatible with open networks as described above. 17 can be transmitted.

Moreover, in the said 1st and 2nd embodiment, although the case where the whole food processing facility 2 was managed by the one management server 17 was demonstrated, it is not limited to this, The scale of a food processing facility is large. In this case, distributed management may be performed by a plurality of management servers.
Furthermore, in the said 1st and 2nd embodiment, although the case where cooking temperature and cooking time data were collected as food processing data was demonstrated, it is not limited to this, The temperature in the food processing facility 1, Humidity is also detected at the same time, and the set temperature of the refrigerator and freezer can be corrected according to the detected temperature and humidity, and the amount of water and hot water used in the food processing facility 1 and the amount of gas used are also detected. Thus, by transmitting these detection data to the management server 17, the whole food processing facility can be centrally managed.

  Furthermore, in the first and second embodiments, the case where the hygiene management process, the analysis process, and the energy consumption management process of the relatively large-scale food processing facility 1 are described has been described. However, the present invention is not limited to this. Rather, the number of devices arranged in the food processing facility 1 can be any number, and the installed devices are not limited to the above, but are arbitrary devices such as washing machines, disinfecting machines, food packing machines, etc. Furthermore, the present invention can be applied to small-scale food processing facilities such as a kitchen of a restaurant.

In the first and second embodiments, the case where the management server 17 performs the food sanitation management process, the analysis process, and the energy consumption management process has been described. Only the processing may be executed.
In the first and second embodiments described above, the case of detecting the interphase voltage and phase current on the power source side of the three-phase / single-phase composite transformer 7 is described, but the present invention is not limited to this. The interphase voltage and the total current on the power source side of the power receiving equipment in the food processing facility may be detected, and the voltage and current of a single phase 100V may be detected in a small food processing facility.

Furthermore, although the case where the management server 17 is connected via the Internet has been described in the above embodiment, the present invention is not limited to this, and may be connected via another dedicated line or the like. Direct connection to the open network 14 may be used, and another network such as another local area network may be applied instead of the open network 14.
Furthermore, the management server 17 may be operated by a company that operates the food processing facility 1 or may be operated by entrusting it to an external contract management company.
