EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of the elevator apparatus of this invention is described using drawing. In addition, in the following description, the door open means a state that includes a case in which the door is not in the closed state (that is, a state in which the door is not fully opened but half-opened rather than closed). It is.

Embodiment 1.

BRIEF DESCRIPTION OF THE DRAWINGS It is a block diagram of the elevator apparatus in Embodiment 1 of this invention. The elevator apparatus includes car position detecting means (1), platform door opening / closing detecting means (2), car door opening / closing detecting means (3), gate opening prevention means (4), car moving means (5), and virtual doors. The opening / closing signal generation means 6, the car 10, the car door 11, and the boarding point door 12 are provided. Here, the landing door opening and closing detection means 2 and the car door opening and closing detection means 3 correspond to the door opening and closing detection means.

Moving and stopping of the car 10 of the elevator are controlled by the car moving means 5. In addition, the open door departure preventing means 4 has a function of stopping the car 10 when the open door departure state is detected. The virtual door opening and closing signal generating means 6 has a function of generating a dummy signal in the test mode and giving the opening and closing prevention means 4 to verify the opening and closing prevention function.

Next, a concrete operation will be described centering on the verification operation of the gate departure preventing function which is a technical feature of the first embodiment.

The car position detecting means 1 detects the position of the car 10. Further, the landing door opening and closing detection means detects the opening and closing state of the landing door 12 provided in each floor. In addition, the car door open / close detection means 3 detects the open / close state of the car door 11 provided in the car 10.

In the normal driving mode, the opening door departure preventing means 4 receives a detection signal from each of the car position detecting means 1, the landing door opening and closing detecting means 2, and the car door opening and closing detecting means 3, respectively. do. And the opening stop prevention means 4 is the position of the cage | basket | car 10 detected by the cage | basket | car position detection means 1 is a door open traveling range (range which may move the cage | basket 10 in the door open state). If the departure door and the landing door is not closed, or the car door 11 is not closed (that is, the door is open), it is determined that the door is opened and the car 10 is stopped. Let's do it.

On the other hand, in the test mode, the open door departure preventing means 4 receives the detection signal from each of the car position detecting means 1 and the virtual door opening and closing signal generating means 6. That is, the opening door departure prevention means 4 substitutes the virtual door opening / closing signal generation means 6 from the virtual door opening / closing detection means 2 and the car door opening / closing detection means 3 in the test mode. As a result, the dummy signal is preferentially received.

And the opening stop prevention means 4 is the position of the cage | basket | car 10 detected by the cage | basket | car position detection means 1 is a door open traveling range (range which may move the cage | basket 10 in the door open state). In the case of a deviation from the signal and receiving a signal in which the door is not closed as a dummy signal from the virtual door open / close signal generating means 6, it is determined that the door is opened and the car 10 is stopped.

Fig. 2 is a flowchart showing a series of processes when verifying the gate opening prevention function in the test mode of the elevator apparatus of Embodiment 1 of the present invention.

First, the car 10 is in the door closed state (that is, the state in which the car 10 is stopped in the range which may be set as the door open in each phase). Both the car door 11 and the landing door 12 are closed (step S21). If the door is open, close the door. At this time, the opening stop prevention means 4 is based on the position of the car 10 detected by the car position detecting means 1, so that the car 10 is within a range of a preset door openable position. It can be determined whether or not.

Next, the virtual door open / close signal generating means 6 outputs a signal in which the door is not in the closed state as a dummy signal in the test mode of the open door departure prevention function (step S22). On the other hand, the open door departure prevention means 4 is a virtual door open / close signal generation means 6 instead of the landing door open / close detection means 2 and the car door open / close detection means 3 in the test mode of the open door departure prevention function. Is received first (step S23).

Next, the car moving means 5 starts moving the car 10 (step S24), and moves the car 10 out of the door open traveling possible range (step S25). At this time, the opening door departure preventing means 4 determines whether the car 10 is within a preset door open traveling possible range, based on the position of the car 10 detected by the car position detecting means. This can be done (step S26). In addition, the car position detecting means 1 may generate a signal indicating that the car position is outside the door open traveling possible range, and input the signal to the open door departure preventing means 4.

As a result, the opening stop prevention means 4 receives the dummy signal from the virtual door open / close signal generation means 6, so that the door 10 remains open even though the car 10 is out of the door open traveling possible range. It is virtually determined that the operation is performed, and the car is stopped (S27). Therefore, after actually moving the car 10 with the door closed, the door opening prevention function can be easily verified.

As described above, according to the first embodiment, in the functional test for preventing the opening and closing of the door, the elevator is actually kept in the closed state by outputting a dummy signal indicating that the door is virtually opened from the virtual door open / close signal generating means. By moving the cells, you can easily obtain the verification results. As a result, it is possible to reliably perform the function test for preventing the opening and closing departure without having to forcibly perform an abnormal operation of running in the door open state.

Embodiment 2.

In the first embodiment, as a dummy signal in the test mode, a signal in which the door is in an open state is virtually generated, and the functional test for preventing the gate opening is easily performed. In contrast, in the second embodiment, a dummy signal in the test mode is used to virtually generate a signal in which the car position is not in the door open traveling range, thereby easily performing the function test for preventing the starting gate departure. .

3 is a configuration diagram of an elevator apparatus according to Embodiment 2 of the present invention. The elevator apparatus includes car position detecting means 1, platform door opening and closing detecting means 2, car door opening and closing detecting means 3, door opening prevention means 4, car moving means 5, and virtual elevator. The car position signal generating means 7, the car 10, the car door 11, and the boarding point door 12 are provided. Compared with the configuration of FIG. 1 in the first embodiment, the configuration of FIG. 3 in the second embodiment includes a virtual car position signal generating means 7 instead of the virtual door open / close signal generating means 6. It is different.

The virtual car position signal generation means 7 has a function of generating a dummy signal in the test mode and giving the opening departure prevention means 4 for the verification of the opening departure prevention function. Therefore, a specific operation will be described mainly on the verification operation of the gate departure preventing function which is a technical feature of the second embodiment. In addition, since operation | movement in normal operation mode is the same as that of Embodiment 1, description is abbreviate | omitted.

In the test mode, the open door departure prevention means 4 receives a detection signal from each of the landing door opening and closing detection means 2, the car door opening and closing detection means 3, and the virtual car position signal generating means 7. Receive. That is, the opening stop prevention means 4 preferentially receives the dummy signal as the virtual car position from the virtual car position signal generating means 7 instead of the car position detecting means 1 in the test mode.

And the opening stop prevention means 4 deviates from the range which the dummy signal from the virtual car position signal generation means 7 can open | move a door open run possibility (range which can lift and move the car 10 in a door open state), In addition, when the landing door is open or the car door is open, it is determined that the door is open and the car 10 is stopped.

Fig. 4 is a flowchart showing a series of processes when verifying the gate opening prevention function in the test mode of the elevator apparatus of Embodiment 2 of the present invention.

First, the car 10 is opened in the door open state (that is, the car 10 is stopped in the range which may be set as the door open in each system), and the door open state (that is, the car door ( 11) and the landing door 12 are both closed (step S41). If the door is closed, open the door.

Next, the virtual car position signal generating means 7 outputs a position signal within the door open traveling possible range as a dummy signal in the test mode of the opening door departure prevention function (step S42). On the other hand, the open door departure prevention means 4 preferentially receives a dummy signal from the virtual car position signal generation means 7 instead of the car position detection means 1 in the test mode of the open door departure prevention function. (Step S43). Next, the car movement means 5 starts moving the car 10 in the door open state (step S44).

Next, the virtual car position signal generating means 7 is a state in which the car 10 is actually within the door open traveling possible range after the start of the movement of the car 10 in the test mode of the gate opening prevention function. In step S45, the position signal outside the door open traveling possible range is output as a dummy signal (step S45). On the other hand, the open door departure preventing means 4 receives the position signal outside the door open traveling possible range as a dummy signal from the virtual car position signal generating means 7 instead of the car position detecting means 1 (step S46). .

As a result, the door stop prevention means 4 receives the dummy signal from the virtual car position signal generation means 7, so that the car 10 is actually within the door open traveling range, It is virtually determined that the door is moving out of the open traveling possible range, and the car 10 is stopped (S47). Therefore, in practice, it is possible to easily verify the gate opening prevention function in the state where the car 10 is located within the door open traveling possible range.

As described above, according to the second embodiment, in the functional test for preventing the starting gate departure, the dummy car outputs a dummy signal indicating that the position of the car is outside the door open traveling possible range from the virtual car position signal generating means. In fact, the verification result can be easily obtained with the state within the door open traveling possible range. As a result, it is possible to reliably perform the function test for preventing the opening and closing of the door without having to forcibly perform an abnormal operation of traveling out of the door open traveling possible range in the door open state.

Embodiment 3.

One of the objectives of the gate starting prevention function is to stop the car at an appropriate position. For this reason, it is important to confirm the position of the stopped car when performing a verification test. Conventionally, however, in order to determine whether this stop position satisfies the required criterion, it has taken time to actually stop the car by moving it and then measure the stop position by the position detection means of the car. Therefore, in Embodiment 3, the case where a display is displayed at a predetermined place so that the stop position of the car 10, which is the result of the function test for preventing the starting departure, can be easily confirmed with the naked eye.

It is explanatory drawing which shows the positional relationship of the elevator apparatus of Embodiment 3 of this invention. In FIG. 5, three marks 30a, 30b, and 30c are provided for visual confirmation. When the car 10 starts to open and close, the reference distance for preventing a person from being caught between the upper frame 22 of the entrance and exit of the hoistway 21 and the car bottom surface 24 is set to L1. . At this time, in order to show the position which can ensure the reference distance L1, the mark attached to the car door 11 is the mark 30a, and the mark attached to the landing door 12 is the mark 30b.

That is, when the car 10 is raised at the time of opening and departure, when the mark 30a reaches the upper frame 22 of the entrance and exit of the hoistway, or when the car bottom surface 24 has reached the mark 30b. In this case, it means that the distance between the car bottom surface 24 and the upper frame 22 of the entrance and exit of the hoistway becomes L1.

In addition, when the car 10 starts to open, a person falls on the hoistway 21 between the toe guard plate 13 of the car and the lower frame 23 of the entrance and exit of the hoistway. The reference distance for preventing this is set to L2. At this time, in order to show the position which can ensure the reference distance L2, the mark attached to the boarding point door 12 is the mark 30c.

That is, when the car 10 is raised at the time of the opening gate and the lower end of the toe protector 13 of the car reaches the mark 30c, the lower end of the toe protector 13 of the car and the entrance and exit of the hoistway It means that the distance of the lower frame 23 is L2.

As described above, according to the third embodiment, a mark is provided at a stop reference position indicating an allowable maximum distance for preventing pinching or falling in the inspection of the opening departure prevention function. This makes it possible to immediately visually determine the relative positional relationship between the car door and the landing door with the car stopped, after the verification operation of the gate opening prevention function, and visually determine whether the inspection result is satisfactory. It becomes possible to confirm.

In addition, in Embodiment 3, the case where the mark was attached to the stop reference | standard position which shows the permissible maximum distance when a car climbs was demonstrated. However, it is also possible to put a mark in the stop reference position which shows the permissible maximum distance when the car descends. Thereby, even when it descends from an opening departure, it becomes possible to visually confirm a test result easily.

In addition, in Embodiment 3, the case where the mark was attached so that the stop reference position which shows a permissible maximum distance may be visually confirmed was demonstrated. However, it is possible to add additional scale so that the distance from this marker is known. By attaching such a scale, the remaining distance to the permissible maximum distance can be easily and immediately visually confirmed.

In addition, as in the second embodiment, even when the functional test for preventing the opening / closing departure using the dummy signal as the virtual car position is performed, the relative moving distance from the output of the dummy signal to the stop is measured from this scale. It is possible to obtain accurate verification results.
