Description

  The present invention relates to a daylight saving time control system and a daylight saving time switching method, and more particularly to a daylight saving time control system for controlling a control internal clock in an elevator to a daylight saving time and a daylight saving time switching method for switching to a daylight saving time.

  When daylight saving time is in effect, the time is advanced by a predetermined time on a predetermined day of the week around June, for example, and the time is returned by a predetermined time on a predetermined day of the week around September, for example. It is also necessary to cope with daylight saving time for equipment in a building, for example, an internal clock for control recording in an elevator. Moreover, it is necessary to correspond to daylight saving time display as seen by passengers in the elevator car.

  In addition, for equipment in a building, for example, an internal clock for control recording in an elevator, time adjustment is periodically performed to adjust the time display deviation. For example, Patent Document 1 discloses a time adjustment method for an elevator control system, in which a monitoring center periodically issues a command for diagnosis, adjustment, etc. to a remote monitoring device, and a watch that is a parent clock provided in the center. It is described that a clock correction command is issued to the remote monitoring device on the basis of the above information.

  On the other hand, Patent Literature 2 discloses a remote monitoring device. Here, at the time of daylight saving time, the information selection unit of the monitoring center sends the recovery management information used for each customer in the various information processed by the control unit and the dispatch instruction information to be transmitted to the dispatch base. It is described that the time information in the selected recovery management information and dispatch instruction information is changed to daylight saving time.

  The operation of daylight saving time may vary depending on the area or building. If the time display of all the buildings is changed at the same time during daylight saving time by the remote management center, there is a risk of confusion. In addition, when daylight saving time is introduced only in some areas, or when daylight saving time is implemented in some areas, daylight savings cannot be handled.

  Further, when the time display in the car is switched regardless of the presence of an elevator passenger at the time of daylight saving time switching, there is a risk that passengers who do not know to switch will feel uneasy.

  Further, if the time is switched regardless of the operation of the elevator control operation, the operation record of the control operation may become discontinuous during the operation, resulting in undesirable data.

  Furthermore, when a passenger is present in the elevator car, the time display of the video recording for photographing the passenger is switched during the photographing, and the time stamp may be discontinuous.

  An object of the present application is to solve this problem and provide a daylight saving time control system and a time switching method for switching the time to an appropriate time zone in accordance with the daylight saving time operation for each building.

  In order to achieve the above object, a daylight saving time control system for an elevator internal clock according to the present invention includes a facility control unit provided in a building and a remote management center that remotely manages the facilities in each building via a communication line.

  Hereinafter, embodiments of a daylight saving time control system and a daylight saving time switching method according to the present invention will be described in detail with reference to the drawings.

(Daylight saving time control system)
FIG. 1 shows a schematic configuration of one embodiment of a daylight saving time control system 1. In FIG. 1, the present invention will be described using a remote management center 10 and three buildings 8a to 8c. As shown in FIG. 1, building transmission / reception units 7a-7c provided in the buildings 8a-8c, and a remote management center transmission / reception unit 6 provided in a remote management center 10 for remotely managing facilities in the buildings 8a-8c. Are connected via a communication line 20. In this embodiment, the remote management center 10 includes a remote management center transmission / reception unit 6, a summer time information storage unit 2, a summer time information management unit 3, and a time adjustment unit 12. Moreover, in this embodiment, the equipment control parts 13a-13c of each building 8a-8c are the building transmission / reception parts 7a-7c, the daylight saving time judgment part 4a-4c, the daylight saving time control part 5a-5c, and the elevator internal clock 14a. 14c.

  In the present embodiment, the equipment in each of the buildings 8a to 8c is an elevator, but is not limited to this, and includes, for example, escalators, air conditioning equipment, lighting equipment, water supply / drainage equipment, and the like. Moreover, about the time regarding an elevator, the time of the time display apparatus 9a-9c of the elevator cars 11a-11c, the time of the video recording of the surveillance cameras 15a-15c which image | photograph the passenger in the elevator cars 11a-11c, for example, control operation of an elevator The time on the operation record of the elevator, the time on the display (not shown) of the elevator hall, etc., but is not limited to this, and includes the time related to each facility in each building 8a to 8c.

  The daylight saving time storage unit 2 in the remote management center 10 individually stores operation information related to daylight saving time for each of the buildings 8a to 8c. The operation information related to the daylight saving time of each building 8a to 8c stored in the daylight saving time information storage unit 2 is added or changed as appropriate, and the latest operation information is stored. For example, in the building 8a, an operation is performed in accordance with a general application time (June to October) regarding daylight saving time. In addition, the building 8b is a foreign-affiliated company, and operates in accordance with the daylight saving time of the home country. In addition, since the area of the building 8c is a cold district, an operation is adopted in which a special application period (July to September) is adopted for daylight saving time. Furthermore, daylight saving time may be introduced on a trial basis only in some areas. Thus, the application time of daylight saving time may vary depending on the buildings 8a to 8c. The remote management center 10 manages daylight saving operation information of the buildings 8 a to 8 c and stores the information in the daylight saving information storage unit 2.

  The summer time information management unit 3 transmits switching information and switching conditions related to summer time based on the operation information stored in the summer time information storage unit 2. As described above, the daylight saving time information management unit 3, when the operation of daylight saving time is different for each of the buildings 8 a to 8 c, sets the daylight saving time for each building transmission / reception unit 7 a to 7 c according to the operation time of each building 8 a to 8 c. Transmit switching information and switching conditions.

  In the present embodiment, the switching information is a “summer time switching time zone”, a “summer time recovery time zone”, and a “change relative time”. The “summer time switching time zone” refers to a designated date or a designated day of the week (for example, the first Sunday in June) and a time to shift from normal time to daylight saving time. “Daylight saving time recovery time zone” refers to a specified date or a specified day of the week (for example, the last Sunday in September) and time to return from the daylight saving time to the normal time. Further, “change relative time” refers to a time difference between normal time and summer time, and is generally one hour.

  The “switching condition” described above has two conditions. The first condition is that “the passengers in the elevator cars 11a to 11c are unmanned”. This is to avoid giving anxiety to the passengers in the elevator cars 11a to 11c when the time display in the elevator cars 11a to 11c is suddenly switched. Further, the condition that the passengers in the elevator cars 11a to 11c are unmanned can prevent the video recording times of the passengers in the elevator cars 11a to 11c from becoming discontinuous. In the present embodiment, whether or not the passengers in the elevator cars 11a to 11c are unmanned is determined by the absence of call registration of the elevator cars 11a to 11c. That is, the state where there is no call registration of the elevator cars 11a to 11c means that there are no passengers in the elevator cars 11a to 11c. Whether or not the passengers in the elevator cars 11a to 11c are unmanned is determined from the operating state of the human sensor or the monitoring cameras 15a to 15c installed in the elevator cars 11a to 11c and the state of the emergency button. good.

  The second condition is “not during elevator control operation”. This is because the control operation is performed to check the operation state of the elevator after an emergency such as a fire or earthquake, but the time of the elevator operation record is discontinuous because the time display changes during the control operation. This is to prevent this. The elevator control operation includes, for example, not only an emergency situation but also an operation for checking the operation of the elevator, a remote check for operating the elevator from a remote location, and the like.

  FIG. 2 shows an example of the summer time switching information and switching conditions transmitted by the summer time information management unit 3 to the buildings 8a to 8c. For the building 8a, the daylight saving time information management unit 3 sets the switching time zone to “June ○ Sunday 2:00 AM to 4:00 AM” and the recovery time zone “October ○” for general switching operation. The change relative time is “1 hour”, the switching condition is “no car call” and “not in control operation”. For the building 8b, the switching time zone is set to “June △ day 3:00 AM to 5:00 AM” and the restoration time zone is set to “Octo △ day 3:00 AM ~ 5:00 AM ”, the change early departure time is“ 1 hour ”, and as a special case, the switching condition is“ no car call ”only. Furthermore, for the building 8c, because of the operation in accordance with the daylight saving time in the cold region, the switching time zone is “July ○ 2:00 AM to 4:00 AM” and the recovery time zone is “September ○ Day 2:00 AM”. ˜4: 00 AM ”, the change relative time is“ 1 hour ”, and the switching condition is transmitted as“ no car call ”and“ not in control operation ”.

  The daylight saving time control units 5a to 5c in the equipment control units 13a to 13c of the buildings 8a to 8c control times related to elevators in the buildings 8a to 8c. Further, the daylight saving time control units 5a to 5c check the daylight saving time switching time zone or the daylight saving time restoration time zone and the change relative time. The daylight saving time determination units 4a to 4c determine whether or not the state matches the switching condition described above. That is, it is determined that there is no call registration of the elevator cars 11a to 11c that the passengers of the elevator cars 11a to 11c are unmanned. Also, it is determined that it is not during the elevator control operation.

  Then, when the daylight saving time determination units 4a to 4c determine that the daylight saving time determination units 4a to 4c match the switching condition, the daylight saving time control units 5a to 5c switch the time in the facilities in the buildings 8a to 8c based on the switching information. That is, the daylight saving time control units 5a to 5c switch the time of the internal clocks 14a to 14c for control recording in the elevator, and switch the time display in the elevator cars 11a to 11c according to the time of the internal clocks 14a to 14c. Moreover, the time display of the video recording of the passengers by the monitoring cameras 15a to 15c in the elevator cars 11a to 11c is also switched. In general, switching is performed at 2:00 to 4:00, which is likely to have no elevator passengers, but different time zones are set depending on the buildings 8a to 8c. The daylight saving time control units 5a to 5c forcibly switch the time display only for the changed relative time when the switching condition is not met even when the last time of the daylight saving time switching period, for example, 4:00 AM, is reached.

  The summer time information management unit 3 notifies the time adjustment means 12 of the remote management center 10 that adjusts the time of the deviation of the elevator internal clocks 14a to 14c by remote communication, with the switching information related to summer time. That is, the time adjustment means 12 in the remote management center 10 periodically checks the time of the equipment of each building 8a to 8c and corrects the time error. This is because when the time adjusting unit 12 does not recognize that the time has been switched due to daylight saving time, the time adjusting unit 12 determines that the changed relative time is an error in time. Therefore, the daylight saving time information management unit 3 notifies the time adjustment unit 12 of switching information related to daylight saving time, and recognizes that the time has been switched by the changed relative time.

(Daylight saving time switching method)
FIG. 3 shows a flowchart of one embodiment of the daylight saving time switching method in the remote management center 10. First, operation information related to daylight saving time for each building 8 is stored (S100). It is determined whether or not operation information relating to the stored daylight saving time has been added or changed (S101). If there is an addition or change, the operation information of the building 8 is corrected (S102) and the latest operation information is stored. (S101). Next, switching information and switching conditions are set according to operation information related to daylight saving time (S103), and the information is transmitted to the equipment control unit 13 of the building 8 (S104). The switching information includes a summer time switching time zone, a summer time recovery time zone, and a change relative time. In addition, the switching condition includes that there is no car call registration and that the elevator is not in control operation. And it is judged whether switching information and switching conditions were transmitted to all the buildings 8 used as object (S105). Furthermore, the time adjustment means 12 is notified of switching information related to summer time (S106).

  FIG. 4 shows a flowchart of one embodiment of the daylight saving time switching method in the equipment control unit 13 of each building 8. First, it is determined whether daylight saving time switching information and switching conditions have been received from the remote management center 10 (S201). If it is received, the equipment control unit 13 of the building 8 determines whether or not it corresponds to the daylight saving time switching time zone (S202), and determines whether or not it corresponds to the daylight saving time recovery time zone (S203). . When it corresponds to either the daylight saving time switching time zone or the daylight saving time recovery time zone, it is determined whether or not the switching condition is met (S204). When it is determined that the time matches the switching condition, the time in the elevator in the building 8 is switched by the changed relative time based on the summer time switching time zone or the summer time recovery time zone (S206). That is, the time of the internal clock 14 for control recording in the elevator is switched, and the time display in the elevator car 11 is switched according to the time of the elevator internal clock 14. If it is determined that the time does not meet the switching condition, S204 is repeated until the time is met. However, if the last time of the time zone is reached (S205), the time in the elevator in the building 8 is forcibly changed to the relative time. Only switch (S206).

  As described above, the remote management center 10 individually manages the daylight saving time of the buildings 8a to 8c according to the daylight saving time operation of the buildings 8a to 8c, and determines the daylight saving time switching condition in each of the buildings 8a to 8c. It becomes possible to switch the time in an appropriate time zone by making the equipment control units 13a to 13c of the respective buildings 8a to 8c determine.
