  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings. First, the thermostatic chamber constituting the sign monitoring system will be described, and then the entire sign monitoring system will be described.

(Whole structure of the thermostat 1)
FIG. 1 is a front view illustrating an example of a thermostatic chamber described in the embodiment. FIG. 2 is a left side view schematically showing an example of the internal structure of the thermostatic chamber 1 shown in FIG. FIG. 3 is a side view on the right side of the thermostat 1 shown in FIG. FIG. 4 is a rear view of the thermostatic chamber 1 shown in FIG. FIG. 5 is a plan view of the thermostatic chamber 1 shown in FIG.

  The thermostatic chamber 1 is a box-type storage that is managed with an internal temperature precisely controlled by a sign monitoring system (for example, a sign monitoring system S shown in FIG. 14 described later). For example, as illustrated in FIG. 2, the thermostatic chamber 1 can store a plurality of bottles B, which are examples of storage objects, preferably in a state of maintaining a low temperature state. It is also called a thermostat or refrigerator. The thermostatic bath 1 has a temperature inside the thermostatic bath 1 so that the bottle B containing the chemicals shown in FIG. 2 can be kept at a low temperature in a predetermined temperature range (for example, a range of 3.5 ± 1.0 ° C.). Control and store. In addition, in this specification, the temperature of the storage object L (chemical | medical agent etc.) accommodated in the bottle B is suitably called the temperature of the bottle B for simplification of description.

  As shown in FIGS. 1 to 3, the thermostatic chamber 1 includes a main body 2 and a door (door) 3. The main body 2 and the door 3 are made of metal, for example, made of SUS (stainless steel). The main body 2 is preferably a box-shaped container. As shown in FIG. 1, the main body 2 forms an upper surface plate 4 that forms the upper surface side, a lower surface plate 5 that forms the lower surface side, side surface plates 6 and 7 that form the left and right side surfaces, and a back surface side. It has a back plate 8 and a front plate 9 that forms the front side (front side). The main body 2 is provided with casters 5 </ b> A for enabling movement at the lower four corners of the lower surface plate 5.

  Hereinafter, for simplification of explanation, the upper surface plate is simply the upper surface (for example, the upper surface plate 4 is the upper surface 4), the lower surface plate is simply the lower surface (for example, the lower surface plate 5 is the lower surface 5), and the side surface plate is simply the side surface (for example, the left and right sides). The face plates 6 and 7 are appropriately described as side surfaces 6 and 7, the back plate is simply referred to as the back surface (for example, the back plate 8 is the back surface 8), and the front plate is simply referred to as the front surface (for example, the front plate 9 is the front surface 9).

  As shown in FIG. 2, the main body 2 has a housing portion 20 inside. The front surface 9 of the main body 2 is provided with a vertically long rectangular opening 10 for taking the bottle B and the like into and out of the accommodating portion 20. As shown in FIGS. 1 and 2, for example, a single-open rectangular door 3 is attached to the main body 2 using a hinge portion 11 so as to be openable and closable. The accommodating part 20 in the main body 2 keeps the sealing and heat insulating properties against the outside by closing the opening 10 with the door 3.

  As shown in FIG. 1, the door 3 has a light-transmitting, for example, rectangular observation window 12 so that the inside of the housing portion 20 of the main body 2 can be seen. The observation window 12 is fitted with, for example, transparent pair glass. By using the pair glass as the observation window 12, the door 3 can secure heat insulation and can easily maintain the cooling state in the housing portion 20, as compared with the case of using an ordinary single plate glass.

  As shown in FIG. 1, the door 3 includes a handle 3A, an electromagnetic door lock 13, and a key device 14 used in an emergency.

  As shown in FIGS. 1 and 3, a monitor display unit 15 is disposed on the upper surface 4 of the main body 2. The monitor display unit 15 is, for example, a color liquid crystal display unit, and by the user touching the screen, various information displays, items to be instructed to the main body 2, and the like can be input. As shown in FIG. 3, the monitor display unit 15 is supported by the legs 16 with respect to the upper surface 4, and the position and posture of the monitor display unit 15 can be freely changed using the legs 16. Can do.

  The electromagnetic door lock 13 shown in FIG. 1 allows the user to lock the door 3 or reversely unlock the door 3 by receiving authentication in the main body 2. For example, when the user inputs a predetermined password by touch input or brings an authentication card closer to the screen 15A of the monitor display unit 15, the user locks the door 3 or conversely the door. 3 can be unlocked.

  The electromagnetic door lock 13 performs a locking operation of the door 3 upon receiving power supply from a commercial power source, for example. Thus, since the door 3 is equipped with the electromagnetic door lock 13, when the thermostat 1 is performing the normal continuous operation, a person other than the authenticated user cannot open the door 3. . Therefore, as shown in FIG. 2, the bottle B stored in the storage unit 20 of the thermostatic chamber 1 cannot be taken out by a person other than the authenticated user. Thereby, when the thermostat 1 keeps the bottle B continuously at a low temperature, the security in storing the bottle B can be maintained.

  In an emergency, for example, when a power failure occurs, the electromagnetic door lock 13 is not energized from the commercial power supply, so the door 3 is unlocked. If power is supplied from an uninterruptible power supply (UPS power supply) at the time of a power failure, the door 3 can be kept locked by the electromagnetic door lock 13. However, when there is no energization from the uninterruptible power supply, the user inserts the key into the key device 14 shown in FIG. 1 and turns it so that the door 3 is locked (locked) and the door 3 is opened. Can not be.

  Thereby, in an emergency such as when the thermostat 1 cannot receive power supply from the outside due to a power failure, a person other than the authenticated user can store the bottle B stored in the storage unit 20 of the thermostat 1. Since it cannot be taken out, the thermostat 1 can maintain security in storage of the bottle B during a power failure.

  As shown in FIG. 1, an internal temperature display unit 17, a recorder 17 </ b> A, a temperature controller 17 </ b> B, and an independent excessive rise preventer 17 </ b> C are provided on the upper portion of the main body 2. This internal temperature display unit 17 is also called a glycol thermometer, and displays information on the bottle temperature measured by the bottle thermometer 29 in the storage unit 20 shown in FIG. The recorder 17 </ b> A records information on the bottle temperature measured by the bottle thermometer 29, the measured temperature in the container 20, and the like. The temperature adjuster 17 </ b> B adjusts the temperature in the storage unit 20.

  As shown in FIG. 1, an upper limit temperature abnormality display unit 18 </ b> A, a lower limit temperature abnormality display unit 18 </ b> B, a door open / close display unit 18 </ b> C, and an abnormality alarm buzzer 19 are provided on the upper portion of the main body 2. Both the upper limit temperature abnormality display unit 18A and the lower limit temperature abnormality display unit 18B are, for example, red lamps, and the door opening / closing display unit 18C is, for example, a yellow lamp.

  As shown in FIG. 2, the upper limit temperature abnormality display portion 18A shown in FIG. 1 has exceeded the predetermined temperature range (eg, 3.5 ± 1.0 ° C.) (eg, exceeds 4.5 ° C.). At the time), an abnormal rise in the temperature of the bottle B is turned on and alarmed by the command of the control unit 100, and the alarm alarm buzzer 19 warns even with sound. In addition, the lower limit temperature abnormality display unit 18B is configured to instruct the controller 100 when the bottle B falls below a predetermined temperature range (for example, 3.5 ± 1.0 ° C.) (for example, falls below 3.5 ° C.). Thus, an abnormal drop in the temperature of the bottle B is turned on and alarmed, and the alarm alarm buzzer 19 warns even with sound. In addition, the control part 100 comprises the temperature management means 28 which manages the bottle stored in the setting arrangement | positioning area | region Z (refer FIG. 2) mentioned later within the predetermined temperature range.

  The door sensor 18D shown in FIG. 1 detects that the door 3 is open and notifies the control unit 100 of FIG. For example, when the control unit 100 determines that the door 3 has been opened beyond a predetermined time, the door opening / closing display unit 18C in FIG. 1 is lit by a command from the control unit 100 to indicate that the door 3 is open. In addition to alarming, the abnormal alarm buzzer 19 also warns with sound.

(Structure of the accommodating part 20)
Next, with reference to FIG. 2, the structural example of the accommodating part 20 of the main body 2 is demonstrated.

  The inner surface of the housing portion 20 includes a back surface 20D, an upper surface 20F, a lower surface 20G, and left and right side surfaces 20H and 20H (see also FIG. 7). Around the outer sides of the back surface 20D, the upper surface 20F, the lower surface 20G, and the left and right side surfaces 20H and 20H of the storage unit 20, a temperature adjustment air introduction path 30 is provided to adjust the temperature inside the storage unit 20. Yes. That is, the temperature-adjusted air introduction path 30 passes temperature-adjusted air outside the upper surface 20F, the lower surface 20G, the left and right side surfaces 20H, 20H, and the back surface 20D of the accommodating part 20, and this temperature-adjusted air is introduced into the accommodating part 20. The

  An air outlet M through which this temperature-adjusted air enters the housing space of the housing portion is formed in the upper portion of the housing portion 20, and an indoor thermometer 31 is disposed in the vicinity of the air outlet M. In addition, in FIG. 2, although the example which has arrange | positioned the blower outlet M in the back surface 20D is shown, it does not specifically limit to the back surface 20D, It may arrange | position to the upper surface 20F, the lower surface 20G, and the left and right side surfaces 20H and 20H. Moreover, it is also possible to dispose them on all of the back surface 20D, the upper surface 20F, the lower surface 20G, and the left and right side surfaces 20H and 20H.

  Although not shown, the temperature adjustment air introduction path 30 has a heat exchanger and a heater for temperature adjustment on the rear side of the back surface 20D. The heat exchanger and the heater adjust the temperature of the set arrangement region Z in the accommodating portion 20. Thereby, the setting arrangement | positioning area | region Z can hold | maintain the temperature of the bottle B in the range of 3.5 +/- 1.0 degreeC in the state maintained at the low temperature state with the designated temperature.

  A plurality of shelf plates 21 and 22 are arranged horizontally and spaced apart in the accommodating portion 20. Shelf board support portions 23 and 23 are disposed on the left and right side surfaces 20H and 20H, respectively. The left and right shelf support parts 23 and 23 are arranged along the vertical direction and hold both ends of the shelf boards 21 and 22.

  The position of the shelf board 21 in the vertical direction can be arbitrarily changed in the shelf board support portions 23 and 23. On the other hand, the shelf plate 22 positioned at the lowest level is fixed at a height J in the vertical direction. As described above, the position in the vertical direction of the shelf 22 located at the lowest level is fixed in order to arrange a bottle thermometer 29 described below at a position below the shelf 22. Thereby, since the position of this shelf board 22 is fixed, the space for placing the bottle thermometer 29 can be secured, and the shelf board 22 can be prevented from accidentally hitting the bottle thermometer 29.

  As shown in FIG. 2, for example, one bottle thermometer 29 is disposed on the lower surface 20 </ b> G of the storage unit 20. The bottle thermometer 29 measures the temperature of the bottle B, which is an object to be stored, as a dummy of the bottle B, and the temperature of the bottle temperature information BT measured by the bottle thermometer 29 is the temperature of the bottle B. I consider it. The bottle thermometer 29 is an example of a storage object thermometer.

  The bottle thermometer 29 has a dummy bottle. The size and material of the dummy bottle can be the same as that of the bottle B, for example. For example, non-toxic glycol is contained in the dummy bottle as a liquid inside the bottle, and a temperature probe measures the temperature of this glycol.

  This bottle internal liquid is a dummy chemical equivalent to the chemical contained in the bottle B. Thereby, this bottle thermometer 29 can indirectly monitor the temperature of the chemical | medical agent of the bottle B in the accommodating part 20 instead of measuring the temperature of the bottle B in the accommodating part 20 directly.

  For example, one bottle thermometer 29 is placed on the front side inside the housing portion 20 that is easily affected by the external atmosphere of the main body 2. That is, it is preferable that the bottle thermometer 29 is disposed, for example, at a position on the front side near the door 3, which is a position where a temperature change is likely to occur when the door 3 is opened. Thereby, the detection temperature detected by the bottle thermometer 29 can be set to a temperature not higher than the temperature of the medicine in each bottle B.

  The temperature of the bottle temperature information detected by the bottle thermometer 29 is handled as the temperature of bottle B, which is a workpiece. That is, since the temperature of the medicine in the bottle B cannot be directly measured, the temperature of the bottle temperature information measured by the bottle thermometer 29 is treated as the temperature information of the bottle B. The temperature of the bottle temperature information is notified to the control unit 100 shown in FIG. 2 via, for example, a wired communication line. The monitor display unit 15 displays the temperature of the bottle temperature information according to a command from the control unit 100. A control unit 100, a converter 101, and the like are arranged on the upper portion of the main body 2.

  As shown in FIG. 2, a plurality of receiving antennas 40 to 43 are preferably arranged inside the accommodating unit 20 as information receiving units. The antenna 40 is disposed on the upper surface 20F, and the antenna 43 is disposed on the lower surface 20G. The antennas 41 and 42 are disposed on the back surface 20D.

  As shown in FIG. 2, an information transmission function unit 50 for transmitting individual information related to the bottle B is disposed on the bottle B disposed inside the storage unit 20 by pasting, for example. The information transmission function unit 50 of each bottle B stores individual information of the bottle B. In the accommodation unit 20, at least one of the antennas 40 to 43 receives the individual information of the bottle B transmitted from the information transmission function unit 50 by wireless communication and sends it to the control unit 100.

  Antennas 40 to 43 are examples of information receiving units that receive individual information of bottle B. When the information transmission function unit 50 of each bottle B receives an inquiry wirelessly from the antenna 40 to the 43 side, each information transmission function unit 50 stores the individual information of the stored bottle B, for example, the serial number of the bottle B ( Lot number), the weight of the bottle B, the information about the bottle B (medicine) such as the type of the medicine contained in the bottle B, and the like are transmitted wirelessly to at least one of the antennas 40 to 43.

  As described above, since the plurality of antennas 40 to 43 are arranged at different positions in the storage unit 20, the information transmission function unit 50 of each bottle B is located at any position in the storage unit 20. Individual information from can be received reliably.

  The control unit 100 obtains stock information of the bottle B from the individual information about the bottle B received by the antennas 40 to 43. Further, the control unit 100 obtains the weight information of the bottle B from the weight sensor in the housing unit 20. The control unit 100 creates monitoring information of the bottle B from the inventory information and the weight information. The monitoring information can be transmitted from the control unit 100 through the external communication unit 102 to, for example, a predetermined information station outside the main body 2 (for example, a management server 36 described later) wirelessly or by wire. The external communication unit 102 constitutes a transmission unit 34 described later.

(Example of structure for preventing leakage of temperature chamber 1)
Next, a specific example of the leakage prevention structure provided in the thermostat 1 will be described.

  As described above, the antennas 40 to 43 illustrated in FIG. 2 and the information transmission function unit 50 of each bottle B generate electromagnetic waves in the housing unit 20. Leakage preventing means 60 for preventing the generated electromagnetic wave from leaking out of the housing part 20 of the main body 2 to the outside of the main body 2 is disposed in each part of the main body 2. Thereby, electromagnetic waves can be prevented from leaking out of the main body 2, and information relating to the bottle B can be prevented from leaking out of the main body 2. Hereinafter, the leakage preventing means 60, which will be described in detail, is electrically grounded.

(Magnetic member 61 for door)
First, with reference to FIGS. 6 to 8, the door magnetic-shielding member 61 will be described.

  As shown in FIGS. 2 and 6, the main body 2 has a rectangular opening 10, and the door 3 closes the opening 10 so that it can be opened and closed.

  FIG. 6 is an exploded perspective view showing the main body 2 and the door 3. 6 is an example of the leakage prevention means 60, and is located inside the door 3 and at a position corresponding to the periphery of the door 3, that is, the opening 10 in the front surface 9 of the main body 2. It is arranged in the surrounding position. This door magnetic-shielding member 61 is illustrated in FIG. The door magnetic-shielding member 61 is attached to the front surface 9 of the main body 2 along the edge portion forming the opening 10.

  The door magnetic-shielding member 61 has a rectangular frame shape along the edge portion forming the opening 10, and has a structure in which, for example, a conductive material core material is covered with a net-like metal substance. Can be adopted. The door magnetic shield member 61 is electrically grounded. FIG. 7 shows a part of the door magnetic-shielding member 61 arranged in the main body 2, and FIG. 8 is an enlarged view of a portion R shown in FIG. FIG. 9 is a view showing the vicinity of the door magnetic shielding member 61 and the door sensor 18D in the portion N shown in FIG.

  As a result, the door magnetic-shielding member 61 causes the antennas 40 to 43 and the information transmission function unit 50 of each bottle B to generate electromagnetic waves generated in the housing unit 20 between the door 3 and the front surface 9 of the main body 2. This prevents leakage from between the door 3 and the front surface 9 of the main body 2 to the outside of the cabinet.

(Window magnetic shielding member 62)
Next, the window magnetic shielding member 62 will be described with reference to FIGS. 6 and 10. FIG. 10 shows an example of a cross-sectional structure of the transparent plate 63 of the observation window 12.

  As shown in FIG. 6, the door 3 includes a transparent plate 63 that closes the observation window 12 for confirming the inside of the housing portion 20, and a window magnetic shielding member 62 that is disposed around the transparent plate 63. Yes. The window magnetic shielding member 62 is an example of the leakage preventing means 60 and is disposed around the observation window 12. The leakage preventing means 60 is arranged along the portion forming the observation window 12 inside the door 3 so as not to be seen from the outer surface of the door 3.

  As shown in FIG. 10, the transparent plate 63 is preferably a pair glass, and includes a first glass plate 63A and a second glass plate 63B. An air layer 63C is formed between the first glass plate 63A and the second glass plate 63B. Thereby, since the transparent plate 63 is a pair glass and has the air layer 63C, the heat insulation of the transparent plate 63 is improved.

  A film-like transparent plate magnetic shield member 64 is attached to the outer surface 63D of the first glass plate 63A. Further, another transparent plate magnetic shield member 65 in the form of a film is attached to the inner surface 63E of the second glass plate 63B. The transparent plate magnetic shield member 64 and another transparent plate magnetic shield member 65 include, for example, a thin metal mesh member. The transparent plate magnetic shield member 64 and the other transparent plate magnetic shield member 65 are the same as those of the leakage prevention means 60. It is an example. The transparent plate magnetic shield member 64 and another transparent plate magnetic shield member 65 are electrically grounded.

  With this configuration, the window magnetic shield member 62 causes the antennas 40 to 43 and the information transmission function unit 50 of each bottle B to leak electromagnetic waves generated in the housing unit 20 from the vicinity of the observation window 12 to the outside of the storage. To prevent.

(Opening closing magnetic shield member 70 for opening for connection)
Next, with reference to FIG. 3 and FIG. 11, the opening closing magnetic-shield member 70 for the opening for connection is demonstrated.

(Predictive monitoring of multiple temperature chambers in the predictive monitoring system)
FIG. 14 is an explanatory diagram illustrating an example of temperature management of a plurality of thermostatic chambers in the sign monitoring system S according to the embodiment. FIG. 15 is a flowchart illustrating an example of temperature management. FIG. 16 is a graph showing an example of a timing chart showing the relationship between the bottle temperature stored in the storage section of the thermostatic chamber and the time. In FIG. 16, the vertical axis indicates the temperature T (° C.), and the horizontal axis indicates the time.

  The sign monitoring system S includes thermostats 1A, 1B, and 1C as a plurality of thermostats. Bottles for detecting the temperature of the storage object (bottle) in each set arrangement area of each storage unit 20A, 20B, 20C (first storage, second storage, third storage) of each thermostat Thermometers 29A, 29B, and 29C are arranged.

  Each thermostat 1A, 1B, 1C is a temperature which manages the bottle stored in each setting arrangement area Z (refer to Drawing 2) within a predetermined temperature range based on detection temperature of each bottle thermometer 29A, 29B, 29C Management means 28A, 28B, and 28C and indoor thermometers 31A, 31B, and 31C that measure the indoor temperature of each of the accommodating portions 20A, 20B, and 20C are provided. The temperature management unit 28 is, for example, an air cooling unit that strictly controls the temperature in the refrigerator.

  Further, the predictive monitoring system S includes a transmission unit 34 that transmits the detected temperature of each bottle thermometer to the outside of the thermostat, a management server 36 that receives data (temperature) transmitted from the transmission unit 34, and a management server 36. And a monitoring center (determination unit) 38 that determines whether each temperature management unit 28 has an abnormality.

  Here, the customer X possesses and uses the above-described thermostats 1A and 1B, and the customer Y possesses and uses the thermostat 1C. The management company W has a management server 36 and a monitoring center 38. The management company W employs a service staff SX of the customer X and a service staff SY of the customer Y as employees. Data (temperature) of the management server 36 related to the customer X is transferred from the monitoring center 38 to the service staff SX. The data (temperature) of the management server 36 regarding the customer Y is also transmitted from the monitoring center 38 to the service staff SY.

  When the monitoring center 38 determines that at least one of the thermostats 1A and 1B is abnormal, the fact is transmitted to the customer X service staff SX.

  When the service center SX informs the service staff SX that the monitoring center 38 has determined that an abnormality has occurred, the service staff SX notifies the customer X of that fact, and the temperature chamber (at least one of the temperature chambers 1A, 1B) determined to be abnormal. On-site diagnosis will be conducted, and maintenance and repairs will be performed as necessary, and an alternative temperature chamber will be installed.

  In this case, when one of the thermostats 1A and 1B is not determined to be abnormal, the bottle (storage object) in the thermostat determined to be abnormal is immediately transferred to the thermostat not determined to be abnormal. You may contact customer X to move it. Thereby, it is easy to ensure that the temperature management accuracy of the chemicals in the bottle is maintained.

  When the monitoring center 38 determines that the temperature chamber 1C is abnormal, the fact is transmitted to the service staff SY of the customer Y. The service staff SY informs the customer Y to that effect, conducts a field diagnosis on the thermostat 1C determined to be abnormal, and performs maintenance, repair, and installation of an alternative thermostat as necessary.

  Here, although the example in which the sign monitoring system S performs sign monitoring of a plurality of thermostats has been described, a sign monitoring system that performs sign monitoring of one thermostat may be used.

(Specific example of judging whether the monitoring center is abnormal)
Hereinafter, a specific example in which the monitoring center 38 determines that there is an abnormality in the thermostatic chamber will be described with reference to FIG.

  It is determined whether the temperature return time from the start of defrost (that is, the time required for the bottle thermometer 29 to return to the predetermined temperature range from the start of defrost) is within an allowable range (step S1). If Yes in step S1, the process moves to an end (step S5) described later.

  In the case of No in step S1, it is determined whether or not an event outside the predetermined temperature range has occurred more than the specified number of times in the specified period (step S2). If No in step S2, the process returns to step S1.

  In the case of Yes in step S2, a warning notification to the service staff and the customer is performed by automatic transmission (step S3). The warning may be sent by e-mail or the like.

  Then, on-site diagnosis by the service staff (diagnosis of the thermostatic chamber determined to be abnormal) is performed (step S4). Then, after performing necessary measures such as maintenance, the process moves to the end (step S5).

(Specific examples of temperature changes in the temperature chamber)
Hereinafter, with reference to FIG. 16, a specific example of the temperature change in the thermostatic chamber accommodating portion will be described using a timing chart.

  Defrosting starts at 0 (see Def in FIG. 16). After the start of defrosting, the measured temperature (substance temperature) of the bottle thermometer 29 arranged in the set arrangement area exceeds 4.5 ° C. and rises to a little lower than 5 ° C. Then, it reaches 4 ° C. before 1:30. Return.

  Thereafter, the door 3 is opened and closed four times during the period from 8:00 to 12:00. The measurement temperature (substance temperature) of the bottle thermometer 29 is within a predetermined temperature range (3.5 ± 1.0 ° C.).

  When the period from 0 o'clock to 12 o'clock is set as the specified period, monitoring is performed when the measured temperature of the bottle thermometer 29 does not deviate from the predetermined temperature range more than the specified number of times (for example, 3 times or more) within the specified period. The center 38 does not determine that the temperature management means 28 is abnormal.

  The monitoring center 38 determines that the return time from the start of defrosting until the measured temperature (substance temperature) of the bottle thermometer 29 returns to a predetermined temperature range (a range of 3.5 ± 1.0 ° C.) exceeds a predetermined time. May be set to be judged as abnormal. For example, if the predetermined time is 1 hour, the return time is less than 1 hour in this specific example (see FIG. 16), so the monitoring center 38 does not determine that there is an abnormality.

  Even if the monitoring center 38 is set so as to be abnormal when the time from the start of defrosting until the measured temperature (control temperature) of the indoor thermometer 31 reaches the set temperature exceeds the set time. Good. For example, when the set time is 15 minutes and the set temperature is 3.5 ° C., in this specific example, the temperature reaches 3.5 ° C. within 15 minutes (see FIG. 16). I do not judge.

  As described above, according to the embodiment, the predictive monitoring system S includes the thermostat 1, and the thermostat 1 is a bottle thermometer (storage object) stored in the set arrangement region Z in the storage unit 20. Thermometer) and temperature management means 28 for managing the object to be stored (such as medicine) in the bottle within a predetermined temperature range. The predictive monitoring system S includes a transmission unit 34 that transmits the measured temperature to the outside, and a monitoring center 38 (determination unit) that receives the transmitted temperature information and determines whether the temperature management unit 28 has an abnormality. Prepare.

  Therefore, when the monitoring center 38 determines that there is an abnormality, the thermostat can be diagnosed and necessary measures such as maintenance can be taken. Therefore, the predictive monitoring system S is realized that can detect a sign that cannot be managed at a temperature within a predetermined range and can take measures before the failure.

  In addition, a plurality of temperature management units 28 may be installed by installing a plurality of thermostats. In this case, the monitoring center can determine whether each temperature management unit 28 has an abnormality. Thereby, the monitoring center can determine the presence or absence of abnormality for a plurality of thermostatic chambers installed at different locations, and can be managed efficiently.

  Further, the bottle internal liquid of the bottle thermometer 29 is a dummy chemical corresponding to the chemical stored in the bottle B. Thereby, this bottle thermometer 29 can monitor the temperature of the chemical | medical agent of the bottle B in the accommodating part 20 instead of directly measuring the temperature of the bottle B in the accommodating part 20, and accommodates in the bottle B. A temperature very close to the actual temperature of the drug being used can be measured.

  Moreover, it is preferable that the bottle thermometer 29 (storage object thermometer) is arrange | positioned among the setting arrangement | positioning area | regions Z in the area | region of the door side which closes the accommodating part 20 so that opening and closing is possible. Thereby, the detected temperature detected by the bottle thermometer 29 can be set to a temperature not higher than the temperature of the medicine in each bottle B, and the temperature can be managed more reliably.

  Moreover, the bottle thermometer 29 may be arrange | positioned in the area | region farthest from the blowing outlet M which air blows off to the accommodating part 20 among setting arrangement | positioning areas. As a result, the detected temperature detected by the bottle thermometer 29 can be easily set to a temperature not higher than the temperature of the medicine in each bottle B, so that the temperature can be managed more reliably.

  Moreover, the indoor thermometer 31 which measures the temperature in the accommodating part 20 is provided, and the monitoring center 38 is when the time from the start of defrost until the measured temperature of the indoor thermometer 31 reaches preset temperature exceeds preset time. In some cases, it may be configured to determine that there is an abnormality, whereby a sign of abnormality when defrosting is performed can be easily grasped.

  It is also possible to make a predictive monitoring system that does not have a thermostatic chamber. For example, a container 20 for storing a storage object, a bottle thermometer 29 (storage object thermometer) for detecting temperature information of the storage object stored in the set arrangement area Z in the storage unit 20, Based on the detected temperature information, the temperature management means 28 for managing the bottle B (storage object) stored in the set arrangement area Z within a predetermined temperature range, and the transmission means for transmitting the temperature information to the outside of the storage unit 20 34 and a monitoring center (determination unit) 38 that receives the temperature information BT (see FIG. 2) transmitted from the transmission unit 34 and determines whether or not the temperature management unit 28 is abnormal. It is also possible. Then, a plurality of temperature management means 28 may be installed by installing a plurality of storage units 20.

  Even with such a sign monitoring system, it is possible to achieve the same effects as the sign monitoring system S.

  The present invention has been described with reference to the embodiment. However, the above embodiment is merely an example, and the scope of the invention described in the claims can be variously modified without departing from the scope of the invention. .

  In the thermostat 1 of the above-described embodiment, for example, as a storage object, a chemical that needs to be stored at a low temperature of a predetermined temperature is taken as an example. However, the storage object is not limited to this and is a storage object of other types and fields. It may be.

  The number of antennas as the information receiving unit, the arrangement position, and the arrangement attitude are not limited to the illustrated example and can be arbitrarily set. The number and arrangement positions of the bottles B that are the storage objects are not limited to the illustrated example, and can be arbitrarily set.

  The number of shelves 21 arranged is not limited to the example shown in FIG. Further, the door 3 may be a double-opening type (a double door type) instead of a single-opening type.

  Moreover, the chemical | medical agent etc. which require precise temperature control are not restricted to a glass bottle-shaped container, for example, and may be a container of other shapes. In this case, it is preferable that a thermometer for detecting temperature information of a chemical or the like that requires precise temperature management is shaped in accordance with the shape of the container and this chemical or the like is added to measure the temperature.
