  If the mode G is set, the third alarm is issued when the closed state elapsed time exceeds 5 hours and the temperature rise from the door closing time is 2 ° C. or more before the next door opening information is acquired. Corresponding means 6 warns and reports to the terminal 11 provided in the store management unit, and at the same time to the terminals 12a, 12b, 12c such as smartphones owned by the person in charge of handling the freezing / refrigeration equipment 20a. Warnings and notifications are made, and further warnings and notifications are made to the terminal 14 such as a personal computer used by the maintenance / cooling equipment company.

(Correction by alarm response correction means)
As described above, an alarm state release instruction may be received by the monitoring device 1 during a warning response such as the first warning response. This is because the workers who opened the doors of the refrigeration and refrigeration equipment, the store managers who rushed to the refrigeration and refrigeration equipment for handling, and the persons in charge of handling the refrigeration and refrigeration equipment were preset. This is a case where it is determined that the alarm response such as the first alarm response may be canceled at this point and monitoring may be performed again from the beginning.

  Work in freezing and refrigeration equipment is various. For example, it is carried out at the time of delivery when the store where the refrigeration / refrigeration equipment (refrigerator, freezer) is installed is often not open during the night or early morning, and during the time when the store is open The length of time during which work is performed by opening the doors of the refrigeration / refrigeration equipment (refrigerators, freezers) is different from the work for loading and unloading products.

  In the freezer monitoring / warning system of the present invention, the digital information accumulated by monitoring the monitoring device 1 of the freezer monitoring / warning system at what time of day the alarm should be issued. Based on the above, it is possible to issue an alarm in consideration of an appropriate door opening time according to each work process. This is the correction by the alarm corresponding correction means 10.

  For example, the alarm response correcting means 10 is grasped and managed by the monitoring time information management means 8, and the first alarm response, the second alarm response, according to the time when the monitoring device 1 monitors the refrigeration / refrigeration equipment. In response to an alarm such as an alarm, a warning that is to be reported to the information provision target person that is different from a preset information provision target person , Etc. Information is provided.

  Alternatively, the alarm response correction means 10 is grasped and managed by the monitoring time information management means 8, and the first alarm response and the second alarm response are performed according to the time when the monitoring device 1 monitors the refrigeration / refrigeration equipment. In response to an alarm such as an alarm response, in addition to a preset information provision target person, the information provision target person different from the preset information provision target person is also set in advance. Provide information such as warnings to be reported to the information provision target person.

  Further, the alarm response correcting means 10 is grasped and managed by the monitoring time information management means 8, the time when the monitoring device 1 monitors the refrigeration / refrigeration equipment, and the alarm state acquired by the release information response means 9. Based on the information that resets the monitoring state by the monitoring device 1 based on the release instruction and starts the monitoring state from the beginning, the predetermined time that is set in advance to perform the alarm response related to the alarm state release instruction Is corrected to a time longer than the predetermined length of time.

  For example, when the store where the refrigeration / refrigeration equipment (refrigerator, freezer) is installed is often open at night or early morning when it is not open, cold air leaks, such as when it is half open, If you know the situation, the freezer monitoring / warning system is owned by the person who is doing the debuddy work, not the store manager or the warning / notification to the person in charge of handling refrigeration equipment. Alerts and reports can be made to terminals such as smartphones. Upon receipt of the warning or notification, the delivery worker can immediately return to the place of the freezer / refrigerator (refrigerator, freezer) and completely close the door.

  Also, during such times, alerts and reports from the freezer monitoring / alarm system to contracted external security companies, etc., and alerts / reports to that effect to the company that the security company is delivering. By doing this, a warning is issued to the person who is performing the delivery work from the security company, and the delivery person who received the warning and the report immediately returns to the place of the refrigeration / refrigeration equipment (refrigerator, freezer) By performing complete closure, it is possible to prevent the door from being continuously opened for a long time when there are no store personnel outside the store opening hours.

  Alternatively, by issuing an alarm and notification to the terminal of the person in charge of the refrigeration / refrigeration equipment who is not at work because it is outside the store's business hours, the person in charge of the refrigeration / refrigeration equipment is in charge of delivery work. The delivery worker who received the warning / report and immediately received the warning / report returned immediately to the place of the refrigeration / refrigeration equipment (refrigerator, freezer) and closed the door completely. When there are no store personnel, it is possible to prevent the door from being continuously opened for a long time.

  Further, the alarm response correcting means 10 includes the time that is monitored and managed by the monitoring time information management means 8 and the time when the monitoring device 1 monitors the refrigeration / refrigeration equipment, and the alarm state cancellation acquired by the cancellation information response means 9. Based on the information that resets the monitoring state by the monitoring device 1 based on the instruction and starts the monitoring state from the beginning, the predetermined time that is set in advance to perform the alarm response related to the alarm state cancellation instruction Then, a process of correcting to a time longer than the predetermined length of time is performed.

  According to this, when the door opening time becomes long due to delivery of goods in the delivery operation, an operator or the like sends an alarm state release instruction to the monitoring device 1 to reset the monitoring state by the monitoring device 1. It is unnecessary to make the monitoring state start from the beginning.

  The presence of the alarm corresponding correction means 10 allows the monitoring device 1 composed of a computer to adjust a predetermined time, a predetermined temperature rise, a temperature drop width, and the like when performing learning and monitoring. is there.

  FIGS. 10, 11 and 12 illustrate an example of monitoring the open state of the refrigerator / freezer door by the refrigerator / freezer monitoring / alarm system of the present invention.

  Workers who carry products in and out of refrigeration / refrigeration equipment such as refrigerators and freezers close the door of the refrigeration / refrigeration equipment at the end of work, and recognize that the door has been closed. Nevertheless, the system is suitable for a half-open state like a so-called half-door, or when the door is not completely sealed and there is a gap.

  Despite the fact that workers have recognized that the door has been closed, there is a half-open state such as a so-called half-door, or a state where the door is not completely sealed and there is a gap. For example, cold air leaks from the inside of the refrigeration / refrigeration equipment through the gap due to deterioration of the packing provided in these parts for the purpose of sealing between the door and the door opening. It also includes situations that may occur.

  In such a refrigerator / freezer digital monitoring / warning system of the present invention, in such a case, when the cold air leaks little by little from the inside of the freezer / refrigerator and the temperature inside the refrigerator gradually rises, this is detected by the detecting means. A person who is working in the vicinity of refrigeration / refrigeration equipment before reaching an alarm temperature at which an emergency response or dispatch request is automatically notified to an external security company, etc. , A store management system consisting of computers such as personal computers (PCs) installed in the management department of the store where the refrigeration / refrigeration equipment is installed, etc., the person in charge of handling the refrigeration / refrigeration equipment in the store To the person-in-charge terminal such as a smartphone owned by the person.

  In the freezer monitoring / alarm system of the present invention, the monitoring device 1 of the freezer monitoring / alarm system monitors what time zone in the day the alarm should be issued.

  Refrigeration and refrigeration equipment (refrigerators, freezers) where the store where the store is installed is often open late at night or early in the morning. In the carry-in / out operation, the length of time for performing work by opening the doors of the refrigeration / refrigeration equipment (refrigerator, freezer) is different.

  In the freezer monitoring / warning system of the present invention, the digital information accumulated by monitoring the monitoring device 1 of the freezer monitoring / warning system at what time of day the alarm should be issued. Based on the above, it is possible to issue an alarm in consideration of an appropriate door opening time according to each work process.

  For example, when the store where the refrigeration / refrigeration equipment (refrigerator, freezer) is installed is often open at night or early morning when it is not open, cold air leaks, such as when it is half open, If you know the situation, the freezer monitoring / warning system is owned by the person who is doing the debuddy work, not the store manager or the warning / notification to the person in charge of handling refrigeration equipment. Alerts and reports can be made to terminals such as smartphones. Upon receipt of the warning or notification, the delivery worker can immediately return to the place of the freezer / refrigerator (refrigerator, freezer) and completely close the door.

  Also, during such times, alerts and reports from the freezer monitoring / alarm system to contracted external security companies, etc., and alerts / reports to that effect to the company that the security company is delivering. By doing this, a warning is issued to the person who is performing the delivery work from the security company, and the delivery person who received the warning and the report immediately returns to the place of the refrigeration / refrigeration equipment (refrigerator, freezer) By performing complete closure, it is possible to prevent the door from being continuously opened for a long time when there are no store personnel outside the store opening hours.

  Alternatively, by issuing an alarm and notification to the terminal of the person in charge of the refrigeration / refrigeration equipment who is not at work because it is outside the store's business hours, the person in charge of the refrigeration / refrigeration equipment is in charge of delivery work. The delivery worker who received the warning / report and immediately received the warning / report returned immediately to the place of the refrigeration / refrigeration equipment (refrigerator, freezer) and closed the door completely. When there are no store personnel, it is possible to prevent the door from being continuously opened for a long time.

  According to the refrigerator / freezer monitoring / alarm system of the present invention, the temperature state in each of the plurality of refrigeration / refrigeration equipments, detection of door open / closed state, detection and determination of abnormal state by calculation, store manager and importer responsible Anomaly information, including, can be automatically notified by lamps, buzzers and emails. For example, the following monitoring and warning are performed.

<Normal work time excess warning>
Calculate the normal work time and elapsed door open time for each type of refrigeration / refrigeration equipment, etc., and when the door is open when the normal work time is exceeded, a “door open alarm” will be sent by warning light / buzzer report.

  As illustrated in FIG. 12, the refrigerator / freezer such as a refrigerator or freezer is a freezer / refrigerator according to what kind of product is accommodated, such as fruits and vegetables, meat, fresh fish, and frozen food. -The internal temperature set for each refrigeration equipment is different. In addition, the time required for putting in and out of goods varies depending on the characteristics of the goods to be taken in and out of the refrigeration / refrigeration equipment.

  Therefore, the allowable work time length is stored as data for each refrigeration / refrigeration device monitored in the database 10 of the monitoring device 1 having a computer configuration. The elapsed time of the door opening from the time of opening the door portions 22 and 23 acquired from the door opening / closing state detecting means 25 provided in the door portions 22 and 23 of the respective refrigeration / refrigeration equipments 20 and 21 is measured by the time measuring means 2.
