It is a figure which shows the hardware structural example of the control apparatus which concerns on embodiment.

Hereinafter, the notification system according to the embodiment will be described in detail with reference to the drawings. First, the functional configuration of the notification system will be described with reference to FIG.

The notification system 100 according to the present invention includes a car position detecting device 1 for detecting the position of an elevator car, and a hatch door unlocking detecting device 2 for detecting a locked state or an unlocked state of a hatch door. The notification system 100 includes a buzzer and the like in the configuration, and a notification device 3 for notifying the maintenance worker and the user by sounding the buzzer, and a maintenance worker operating the up and down movement of the car on the car. And a car elevator operating device 4.

In addition, the notification system 100 includes a lighting device 21 (21a, 21b, 21c,..., 21n) provided in an elevator hall (hereinafter referred to as an elevator hall or simply a hall) on each floor, and turning on/off the lighting device 21. Human motion sensors 5 (5a, 5b, 5c,..., 5n) provided on each floor, which are used for controlling The human sensor 5 detects whether a person is in the hall, and turns on the illumination device 21 in conjunction with the detection. The lighting device 21 and the human sensor 5 may be existing ones.

In addition, the notification system 100 controls the control device 7 (control unit) having the storage unit 7a, the calculation unit 7b, and the communication unit 7c, the detection state of the human sensor 5 on each floor, and the lighting/extinguishing state of the lighting device 21. And a communication device 6 for transmitting to.

Next, an overall outline of an elevator to which the notification system 100 according to the present embodiment is applied will be described below with reference to FIG.

The elevator 200 controls the car 8 on which the user A board, the counterweight 10 connected to the car 8 by the main rope 9, and the vertical movement of the car 8 and the counterweight 10 around which the main rope 9 is wound. It has a winding machine 11. Further, the elevator 200 has the car position detection device 1 attached to the hoist 11 and the hoistway 12 through which the car 8 and the counterweight 10 travel. The elevator 200 is provided so as to divide the elevator hall 13 and the hoistway 12 on each floor, and has a hatch door 14 for blocking the entry of the user A when the car 8 is not on the floor.

The elevator 200 includes a hatch door locking device (not shown) for maintaining the closed state of the hatch door 14, a hatch door unlocking detection device 2 for detecting that the hatch door 14 is in an unlocked state, and a maintenance worker B rides during maintenance work. It has a car elevator operation device 4 for operating the up and down movement of the car on the car 8 and a notification device 3 for notifying the maintenance worker B and the user A of the state by a buzzer sounding or the like.

The elevator 200 is installed in each elevator hall on each floor, and is installed on each floor to irradiate infrared rays or the like to detect the entrance of the user into the hall, and when there is a user, the illumination device 21 is installed. It has a human sensor 5 for lighting. The elevator 200 includes the communication device 6 that receives the detection signal of the human sensor 5 through the wiring 301 and transmits the detection signal to the control device 7 through the wiring 303.

The communication device 6 is also connected to the lighting device 21 via the wiring 302, and inputs an ON/OFF signal of the lighting device 21 from the lighting device 21. When the human sensor 5 does not detect the entrance of the user in the elevator hall, the notification system 100 according to the present embodiment detects this when the lighting device 21 is manually turned on (lighted) by the user. Then, it can be treated as if the user is in the hall. That is, in the configuration in which the human sensor 5 is not used, the notification system 100 treats that the user is in the hall on the floor where the lighting device 21 is turned on, and the floor where the lighting device 21 is turned off, It is possible to treat the user as not in the hall.

In the present embodiment, it is assumed that the wires 301 to 303, which are physical wired cables, are connected to each other, but wireless communication may be used instead. When a physical cable is used, it is necessary to make a hole in the wall of the facility to attach the cable, but by using wireless communication, such a problem can be suppressed.

Subsequently, an operation example of the notification system 100 will be described with reference to FIG. The flowchart shown in FIG. 3 is executed when the maintenance worker switches the elevator 200 to the maintenance operation and turns on the car maintenance switch that enables the operation of the car on the car 8. Further, in the flowchart of FIG. 3, it is assumed that the human sensor 5 is used to detect whether or not the user is in the elevator hall.

First, the control device 7 determines whether the maintenance worker gets on the car 8 and operates the car elevator operation device 4 to cause the car 8 to run and stop (S001). It is made to wait (loop of S001-No). When the control device 7 detects the stop of the car 8 (S001-Yes), the control device 7 acquires the current stop position of the car 8 from the car position detection device 1 (S002).

The control device 7 determines whether the current stop position of the car 8 is a position where the maintenance worker can get on and off the car from above the car by comparing the floor information given in advance (S003). When the car is stopped at the position where the passenger can get on and off the car (S003-Yes), the control device 7 determines whether the work at the position is finished and the traveling is started again (S004), or the maintenance worker. Determines whether to perform the unlocking operation of the hatch door 14 (S005), and waits until these are performed (loop of S004-No and S005-No).

If the car position is outside the range where the passengers can get on and off the car (S003-No), or if the vehicle starts traveling again (S004-Yes), the process returns to step S001 and waits until the elevator car 8 stops. Yes (S001-No loop).

When the hatch door unlocking detection device 2 detects the unlocking of the hatch door 14 (S005-Yes), the control device 7 acquires the operating state of the human sensor 5 in the elevator hall via the communication device 6 (S006). It is determined whether the current position of the car 8 and the operating floor of the motion sensor 5 match (S007). When they match (S007-Yes), the control device 7 activates the notification device 3 and sounds the buzzer for a certain period of time to notify the maintenance worker that there is a user in the hall (S008). With this ringing, the user can also recognize that the elevator is performing maintenance work.

After that, when the hatch door unlocking detection device 2 detects that the hatch door 14 is locked (S009-Yes), the process returns to step S004. By returning the processing to step S004 in this way, when the user enters the hall before the hatch door 14 is unlocked again on the same floor, the notification device 3 sounds the buzzer.

In step S009, when the hatch door 14 remains unlocked (S009-No) and the car maintenance switch is turned off (S010-Yes), the control device 7 finishes the maintenance work, and The processing is finished as if the vehicle 8 had fallen from above. On the other hand, in step S010, when the on-car maintenance switch remains on (S010-No), the process returns to the lock determination of step S009.

A specific example in which the buzzer sounds based on the above operation will be described below with reference to FIG. In describing FIG. 4, FIG. 3 is also referred to as necessary.

The graph of FIG. 4 is a car position graph 15 showing the time transition of the car position, a motion sensor operation state graph 16 showing the detection condition of the motion sensor 5 on each floor, and a hatch door condition graph showing the unlocked condition of the hatch door 14. 17 and a buzzer ringing state graph 18 showing a buzzer ringing state of the notification device 3. Further, the same time axis T is set on the horizontal axis, and the origin is after the start of processing.

The car position graph 15 is a graph in which the car position is plotted on the vertical axis, and the hatched areas 19a to 19d indicate the range of each floor in which the passenger can get on and off the car 8 when the elevator is stopped.

The human sensor operating state graph 16 takes the detection signal of the human sensor 5 on the vertical axis and shows the operating state of the human sensor 5 on each floor by the level of the signal. It is assumed that the human sensor 5 detects a user when the signal is high in the human sensor operating state graph 16. Incidentally, 16a and 19a, 16b and 19b, 16c and 19c, 16d and 19d are shown as having the same floor.

The hatch door state graph 17 shows the detection signal of the hatch door unlocking detection device 2 on the vertical axis in high and low, and indicates that the hatch door 14 is unlocked when the signal is high.

The buzzer ringing state graph 18 shows the operation signal of the notification device 3 on the vertical axis, and indicates that the notification device 3 is activated and the buzzer is ringing when the signal is high.

Hereinafter, each state of T1 to T5 shown in FIG. 4 will be described. The elevator car 8 is running except for T1 to T5, and the process is in the standby state of step S001 (loop of S001-No).

First, at T1, since the elevator is not traveling since it is immediately after the start of the process, the process waits at step S001 and the buzzer does not ring. On the floor where the maintenance work is started, a fence or the like indicating that the maintenance work is being performed is usually provided near the hatch door 14. Therefore, since the user can determine that the maintenance work is being performed by checking the fence, even if the notification device 3 does not ring the buzzer, the effect is limited. On the contrary, for example, in a skyscraper, it is a burden on the maintenance worker to install fences on all floors before maintenance work. Therefore, there are many cases where fences are not provided on intermediate floors. Therefore, in the present embodiment, in the middle floor, when there is a user in the elevator hall, in order to prevent the user from getting in by mistake, the ringing is performed before the door is opened.

Next, at T2, after the elevator travels (S001-Yes), since the vehicle has stopped outside the range of the entry/exit enable position 19, the determination in step S003 returns to step S001, and the process enters a standby state. Therefore, the buzzer does not ring at T2.

At T3, after traveling the elevator (S001-Yes), it stops at a position (19b) where it is possible to get on and off the car 8 (S003-Yes), and the hatch door 14 is unlocked at T3' (S005, graph 17) and the human sensor 5 on the car stop floor is operating (S006, S007-Yes, graph 16b). Therefore, the process proceeds to step S008, and the buzzer sounds for a fixed time. By this buzzer sound, the maintenance worker is informed that there is a user in the elevator hall, and the user is informed that the elevator is under maintenance work and that the hatch door 14 will be opened.

Here, a supplementary description will be given of the operation until the hatch door 14 is opened and the timing of the buzzer ringing. To open the hatch door 14, first, the maintenance operator performs an unlocking operation to unlock the door, and then the maintenance operator manually slides the door to open the hatch door 14. There is a considerable time lag in the work from the unlocking operation to the door opening, and the door is opened a while after the unlocking operation. On the other hand, in the present embodiment, since the processing from the unlocking detection (S005) to the buzzer sounding (S008) is performed instantaneously, the buzzer sounds at the same time as the unlocking. From such a mode, the user can know that the hatch door 14 will be opened at the moment of unlocking (that is, before opening the door) by buzzer sounding. Therefore, the user himself will stop running in when the door is opened. On the other hand, the maintenance worker can know that the user is in the hall by opening the buzzer before opening the door, and can open the hatch door 14 while paying attention.

Continuing to return to the description of FIG. At T3, after that, the hatch door 14 is locked (S009-Yes, graph 17), and when the elevator starts traveling again (S004-Yes), the process returns to step S001, and the process enters a standby state (S001-No loop).

Next, in the front part T4′ of T4, the elevator stops at the position (19c) where the passenger can get on and off the car 8 (S001-Yes, S003-Yes), and the hatch door 14 is unlocked (S004-No). , S005-Yes, graph 17). However, since the human sensor 5 on the car stop floor is not operating and there is no user in the elevator hall on the floor (S006, S007-No, graph 16c), the buzzer does not ring.

After that, the hatch door 14 is closed and locked (S009-Yes, graph 17), and when the hatch door 14 is unlocked again at the same car position without traveling again (T4'', S004-No, S005-Yes). , Graph 17), the control device 7 again acquires the operation state of the motion sensor 5 via the communication device 6 (S006). Then, if the motion sensor 5 is operating at the unlocking timing (S007-Yes), the control device 7 determines that the user has appeared in the hall while the hatch door 14 is in the closed state, and is constant. A buzzer sounds for a time (S008) to notify both the maintenance worker and the user. After that, the hatch door is locked again (S009-Yes), and when the elevator runs (S004-Yes), the process enters a standby state in step S001 (loop of S001-No).

Next, at the front stage of T5, the elevator stops at the position (19d) where the passenger can get on and off the car (S001-Yes, S003-Yes), and the hatch door 14 is unlocked (S005-Yes, Graph 17). Since the human sensor 5 on the stop floor is not operating (S006, S007-No, graph 16d), the buzzer does not ring.

In the middle of T5, even if the motion sensor 5 operates while the hatch door 14 is unlocked, the buzzer does not ring because the determination is made at the moment the hatch door is unlocked. As described above, when the maintenance worker is working while the hatch door 14 is open, the user can visually recognize this situation and determine that the work is in progress. Therefore, in such a case, the user does not usually get in a rush, so that the influence of not ringing the buzzer is limited.

Finally, a hardware configuration example of the control device 7 described in each of the above embodiments will be described with reference to FIG. The control device 7 has the same hardware configuration as the conventional computer as shown in FIG.

The CPU 501 is a central processing unit that expands a program stored in the ROM 503 or the storage 504 into a RAM 502 (RAM: Random Access Memory) and executes the calculation. The CPU 501 comprehensively controls each hardware inside the control device 7 by executing a program. The RAM 502 is a volatile memory and is a work memory that directly inputs and outputs data to and from the CPU 501. The RAM 502 temporarily stores necessary data while the CPU 501 is executing the program.

The ROM 503 is a non-volatile memory and stores firmware executed by the CPU 501. The storage 504 is an auxiliary storage device such as a flash memory, an SSD (Solid State Drive), and a hard disk drive. The storage 504 stores a program executed by the CPU 501 and control data such as parameters in a nonvolatile manner. Further, it is assumed that the storage 504 is installed with a program for performing the above operation in advance.

The connection I/F 505 is an interface group for connecting to various peripheral devices, and for example, the car position detection device 1, the hatch door unlocking detection device 2, the notification device 3, the car elevator operation device 4, and the communication shown in FIG. Responsible for connection with the device 6 and the like.

The communication device 6 is also a computer and has the same hardware configuration as the control device 7 shown in FIG. The wirings 301, 302, and 303 are connected to the connection I/F of the communication device 6. With this configuration, as described above, the communication device 6 inputs the detection signal of the motion sensor 5 of each floor via the wiring 301 and the ON/OFF signal of the lighting device 21 of each floor via the wiring 302. The values of these signals can be output to the control device 7 via the wiring 303.

In the notification system 100 of the present embodiment, as described above, since the lighting device 21 and the communication device 6 are connected via the wiring 302, when the lighting device 21 is manually turned on (lighted) by the user. By detecting this, mounting without the presence of the motion sensor 5 is also possible. In this way, when the person in the elevator hall is not entered by the motion sensor 5 but is turned on/off by the lighting device 21, step S006 in FIG. It will be an action such as "Yes". Further, step S007 is a determination operation such as "whether the car position and the floor on which the lighting device 21 is turned on match". Further, in FIG. 4, the human sensor operating state graph 16 is regarded as a graph showing the ON/OFF signal of the lighting device 21, and the same explanation as above can be applied as it is.

In the above-described embodiment, the implementation example in which the notification device is activated to make the buzzer sound when the lighting device on the floor corresponding to the current stop position of the car is in the lighting state has been described. As a method for determining whether the lighting device is in the lighting state, in the present embodiment, the detection of the user by the motion sensor and the lighting of the lighting device are linked, and the detection signal is obtained from this motion sensor to determine the lighting. The implementation example for performing is explained. Also, an implementation example in which an on/off signal is directly acquired from the lighting device and lighting determination is performed based on this signal has been described.

According to the above-described embodiment, when the maintenance worker is in the hall during the work on the car, the buzzer sounds when the hatch door is unlocked, and the elevator is not in a steady state for the maintenance worker and the user. To notify. Therefore, it is possible to prevent the user from misunderstanding that the elevator is normally available, try to get in at the moment the hatch door is opened, and prevent a collision with the maintenance worker.

Further, when the maintenance operator operates the door opening/closing, if the user is in the hall on the door opening/closing floor, a notification operation is performed, and conversely, if there is no user, the notification operation is suppressed. Therefore, by applying this embodiment, it is possible to suppress unnecessary notification operation and prevent generation of unnecessary noise.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications are included. For example, the above-described embodiments have been described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those including all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add/delete/replace other configurations with respect to a part of the configurations of the respective embodiments. Further, each of the above-described configurations, functions, processing units, processing means, etc. may be realized by hardware by designing a part or all of them with an integrated circuit, for example. Further, each of the above-described configurations, functions, and the like may be realized by software by a processor interpreting and executing a program that realizes each function. Information such as a program, a table, and a file that realizes each function can be stored in a memory, a recording device such as a hard disk, an SSD (Solid State Drive), or a recording medium such as an IC card, an SD card, and a DVD.
