Description

Elevator system {ELEVATOR SYSTEM}

This application is based on Japanese Patent Application No. 2018-114472 (filed date: 6/15/2018), which receives preferential benefit from this application. This application includes all the contents of this application by reference to this application.

Embodiment of this invention relates to an elevator system.

In an elevator system, when a building is shaken by an earthquake or the like, the boarding car is guided to the nearest floor by the earthquake control driving apparatus, the door is opened, and the passengers get off. An elevator system provided with an earthquake control driving apparatus includes an S-wave sensor and a P-wave sensor for detecting shaking of a building or a boarding car. The S-wave sensor and the P-wave sensor are provided, for example, in a machine room, hoistway pit, or the like located above the building.

In this type of elevator system, when the shaking subsides, an automatic diagnostic operation is performed as needed, and it is diagnosed whether there is no damage or a problem in the various apparatus which comprises an elevator system. From the standpoint of safety, the automatic diagnostic operation is performed only when the output (gal value) from the S-wave sensor or the P-wave sensor when the earthquake occurs is less than a predetermined reference value. This reference value is set on the basis of the strength limit of various devices constituting the elevator system. When the output from the S-wave sensor or the P-wave sensor exceeds the reference value even once, the maintenance work is performed by a maintenance worker. .

In addition, in an elevator system provided with an earthquake control driving apparatus as described above, an acceleration sensor may be provided in addition to an S-wave sensor or a P-wave sensor for further security. Similar to the S-wave sensor and the P-wave sensor, the acceleration sensor detects shaking of a building and a boarding car and measures a gal value. The acceleration sensor is provided in a machine room, a boarding car, a counterweight, etc. which are located in the upper part of a building, for example.

On the other hand, in order to introduce the output from the acceleration sensor into the elevator control apparatus, a new wiring facility for connecting the acceleration sensor and the elevator control apparatus is required. For this reason, the acceleration sensor has a problem that it must be provided in the place which can arrange a new wiring installation. In order to solve this problem, the technique which transmits the output from an acceleration sensor to an elevator control apparatus using wireless communication is devised.

However, in order to use the above technique, when a communication terminal is installed near the acceleration sensor, a power source for driving the communication terminal is required. In particular, when an acceleration sensor is provided in the counter weight, since the counter weight generally does not have a power supply device, it is necessary to provide a new power supply device (power cord) to the counter weight. This has a problem that it is expensive and not so desirable from a safety point of view.

The problem to be solved by the embodiment of the present invention is to provide an elevator system capable of transmitting an output from a sensor provided on the counter weight to an elevator control device without providing a new power supply device on the counter weight.

According to one embodiment, an elevator system includes a boarding car installed in a hoistway, a counter weight connected to the boarding car and a rope, a sensor provided on the counter weight, and a sensor for measuring the shaking of the counter weight, and the counter weight. A communication terminal provided and wired connected to the sensor, the first communication terminal functioning as a self when communicating with another communication terminal, and the second communication function connected to the first communication terminal so as to be communicable, and functioning as a main phone. A terminal is provided, and a power supply device is provided in the first communication terminal, and power is supplied to the first communication terminal by the power supply device.

[Function configuration: communication terminal (slave)]

Next, with reference to the functional block diagram of FIG. 2, the functional part which the communication terminal CS which functions as a slave is demonstrated. In addition, since the communication terminal CS1 provided in the boarding car 12 and the communication terminal CS2 provided in the counterweight 13 have the same functional part, here, the communication terminal CS2 is demonstrated as a representative example, and it demonstrates here. The description of CS1 is omitted.

Communication terminal CS2 is connected to the acceleration sensor S2 provided in the counterweight 13, for example by wire. In addition, the communication terminal CS2 is connected to the communication terminal CM functioning as a master by radio using the antenna A2.

As shown in FIG. 2, the communication terminal CS2 includes a power supply control unit 101, an input unit 102, a storage unit 103, a detection cycle switching unit 104, a power supply determination unit 105, and a power supply lifetime plate. The government 106, the communication control part 107, etc. are provided.

The power supply control unit 101 supplies power to each functional unit based on a rechargeable battery provided by the communication terminal CS2 or a replaceable battery (these may be collectively referred to as a "power supply device"). However, the power supply control unit 101 does not always supply power to the communication control unit 107, but only supplies power when a power supply instruction output from the power supply determination unit 105 is received. In addition, the power supply control unit 101 periodically outputs the remaining amount information indicating the remaining amount of the battery or the battery to the power supply life determination unit 106.

The input unit 102 receives an input of measurement data indicating a gal value measured by the acceleration sensor S2 for each preset detection period. The input measurement data is stored in the storage unit 103. The storage unit 103 is a storage medium that stores measurement data input to the input unit 102 in time series.

The detection period switching unit 104 reads (acquires) the measurement data each time the measurement data is stored in the storage unit 103, and the gal value represented by the read measurement data is set to zero. It is determined whether it is equal to or greater than one threshold. The detection period switching unit 104 changes (switches) the detection period to a detection period shorter than the present time when it is determined that the gal value represented by the read measurement data is equal to or greater than the first threshold value. . In addition, a 1st threshold value is a value set with respect to the gal value represented by measurement data, and is an index | index for judging whether to change the said detection period to a longer period than the present, or to a short period, for example. 50 [Gal] or the like.

When the power supply determination unit 105 receives a result indicating that the gal value represented by the measurement data is equal to or greater than the first threshold value as a result of the processing performed by the detection period switching unit 104, the power supply is supplied. A power-on command for instructing the control unit 101 to supply power to the communication control unit 107 is output. In addition, although the power supply determination part 105 acquired the result of the process performed by the detection period switch part 104 here, and outputs a power supply instruction based on the result of the acquired process, The power supply determination unit 105 reads the measurement data each time the measurement data is stored in the storage unit 103, and the gal value represented by the read-out measurement data is not limited thereto. It may be determined by yourself whether or not the first threshold value is equal to or higher, and outputs a power-on command to the power supply control unit 101 when the gal value represented by the measurement data is equal to or larger than the first threshold value.

When the power supply life determination unit 106 receives an input of the remaining amount information regularly output from the power supply control unit 101, the power supply life determination unit 106 determines whether the remaining amount of power indicated by the remaining amount information is less than a predetermined value. In addition, when determining that the remaining amount of power indicated by the input remaining amount information is less than the predetermined value, the power supply life determination unit 106 requests a maintenance source to replace the power source for prompting charging of the battery or replacement of the battery. The communication control unit 107 is instructed to output.

As illustrated in FIG. 2, the communication control unit 107 includes a driving permission determination unit 107a, a periodic cycle alarm unit 107b, an exchange request output unit 107c, and the like.

Measurement data indicating a gal value determined to be equal to or greater than the first threshold value, and determines whether the gal value represented by the read measurement data is equal to or greater than the second threshold value. In addition, the operation permission determination part 107a is a signal which shows whether the gal value represented by the read-out measurement data was more than 2nd threshold value, Specifically, the gal value is more than 2nd threshold value. The first signal indicating that the signal is transmitted or the second signal indicating that the gal value is less than the second threshold value is transmitted to the communication terminal CM functioning as a master through the antenna A2 together with the identification code of the communication terminal CS2. do. In addition, the 2nd threshold value is an earthquake-resistant reference value set based on the strength limit of the guide rails 14c and 14d for the counterweight 13, and is set to 600 [Gal] etc., for example.

The constant period newsletter part 107b stores the measurement data (maximum measurement data) which shows the largest gal value among the many measurement data which received input in the said fixed period every fixed period from the storage part 103. The read-out maximum measurement data is transmitted to the communication terminal CM via the antenna A2 with the identification code of communication terminal CS2. In addition, the fixed period includes a plurality of detection periods, for example, a detection period of N times (N is a positive integer) corresponds to one fixed period.

The exchange request output unit 107c transmits the power exchange request along with the identification code of the communication terminal CS2 to the communication terminal CM through the antenna A2 in accordance with the instruction from the power supply life determination unit 106.

[Function Configuration: Communication Terminal (Master)]

Next, with reference to the functional block diagram of FIG. 3, the functional part which the communication terminal CM which functions as a master is demonstrated. The communication terminal CM is connected to communication terminals CS1 and CS2 functioning as slaves by radio using the antenna A1.

As illustrated in FIG. 3, the communication terminal CM includes a power supply control unit 201, a communication control unit 202, a return control unit 203, an output unit 204, and the like.

The power supply control unit 201 supplies the power supplied from the power supply control unit in the elevator control board 11 to each functional unit. In addition, since the power supply control unit 201 receives power supply from the elevator control board 11, unlike the power supply control unit 101 in the communication terminals CS1 and CS2, the power supply control unit 201 receives all the functional units included in the communication terminal CM. Always supply power.

The communication control unit 202 receives various signals and various requests transmitted by the communication terminals CS1 and CS2 functioning as slaves through the antenna A1. Specifically, the communication control unit 202 is a first measurement signal or a second signal transmitted by the driving permission determination unit 107a in the communication terminals CS1 and CS2, and the maximum measurement data transmitted by the periodic cycle reporting unit 107b. , Via the antenna A1, receives a power exchange request transmitted by the exchange request output unit 107c. The received first and second signals are output to the reply control unit 203 and the output unit 204 together with the identification code accompanying these signals. In addition, the received maximum measurement data and the power supply replacement request are output to the output unit 204 together with the identification code accompanying the information.

When the reply control unit 203 receives the input of the first or second signal output from the communication control unit 202 together with the identification code, the reply control unit 203 attaches to the identification code accompanying the first or second signal that received the input. An acknowledgment (acknowledgment) for notifying that the communication terminal CS identified by the first or second signal has been normally received is transmitted (reply) through the communication control unit 202 and the antenna A1.

When the output unit 204 receives an input of the maximum measurement data outputted from the communication control unit 202 at regular intervals together with an identification code, the output unit 204 is identified by an identification code accompanying the maximum measurement data that receives the input. The communication terminal CS and the life and death signal indicating that its own terminal CM is operating normally are output to the elevator control board 11. In addition, when the output unit 204 receives the input of the maximum measurement data output from the communication control unit 202 at regular intervals together with the identification code, the gal value represented by the maximum measurement data is reset. It is determined whether or not the threshold value is equal to or greater than three thresholds, and according to the result of the determination, a status signal (in other words, acceleration sensor S) indicating whether the acceleration sensor S connected to the communication terminal CS identified by the identification code is in operation or stopped. A status signal indicating whether or not an abnormality has occurred is output to the elevator control board 11. In addition, a 3rd threshold value is a value set in order to determine whether the acceleration sensor S is in operation | movement or stop, and the gal value detected at the time of normal operation (normal operation) corresponds to this, for example. Specifically, the third threshold value is set to 30 [Gal] or the like, for example.

When the output unit 204 receives an input such as a first signal or a second signal, a power supply replacement request, or the like, the output unit 204 outputs these signals or requests to the elevator control board 11 together with the identification code accompanying them. .

[Configuration of function: elevator control board]

Next, with reference to the functional block diagram of FIG. 4, the functional part which the elevator control board 11 has is demonstrated. The elevator control board 11 is wired and connected to the communication terminal CM functioning as a master.

The communication control unit 11e receives various types of information with the car control device 21, the door control device 22, and the boarding point control device 30 that are connected by wire. The power supply control unit 11f supplies power to each functional unit included in the elevator control board 11, and has a function of supplying power to the communication terminal CM serving as a master.

[Function Configuration: Operation Control Unit]

In addition, with reference to the functional block diagram of FIG. 5, the functional part which the operation control part 11b contained in the elevator control board 11 has is demonstrated.

As shown in FIG. 5, the driving control unit 11b includes a terminal abnormality determination unit 301, a sensor abnormality determination unit 302, a control operation control unit 303, a power exchange notification unit 304, and the like. .

The terminal abnormality determination unit 301 determines whether or not an abnormality has occurred in the communication terminals CS1, CS2 and the communication terminal CM based on the presence or absence of the life and death signal inputted from the input / output control unit 11a at regular intervals. In addition, when it is determined that at least one of the communication terminals CS1, CS2 and the communication terminal CM has occurred (possibly high), the terminal abnormality determination unit 301 notifies the maintenance worker of this effect, A prohibition signal for prohibiting automatic diagnosis driving of the boarding car 12 is output to the control driving control unit 303.

The sensor abnormality determination unit 302 determines whether or not an abnormality has occurred in the acceleration sensors S1 and S2 based on the status signal output from the input / output control unit 11a at regular intervals. In addition, when it is determined that at least one of the acceleration sensors S1 and S2 has occurred (highly likely), the sensor abnormality determination unit 302 notifies the maintenance worker of this effect, and the boarding car 12 A prohibition signal for prohibiting the automatic diagnosis operation of?) Is output to the control operation control unit 303.

The control driving control unit 303 controls the control driving operation of the boarding car 12 at the time of an earthquake. Specifically, the control operation control unit 303 is based on the first or second signal corresponding to the communication terminal CS1 output from the input / output control unit 11a and the first or second signal corresponding to the communication terminal CS2. Then, it is determined whether or not it is possible to perform the automatic diagnostic operation, and when it is determined that the automatic diagnostic operation is possible, the automatic diagnostic operation is performed. In addition, when the control operation control part 303 receives the input of the prohibition signal from the terminal abnormality determination part 301 or the sensor abnormality determination part 302, it prohibits automatic diagnostic operation.

When the power exchange notification unit 304 receives the input of the power exchange request output from the input / output control unit 11a, the power exchange notification unit 304 charges or charges the battery of the communication terminal CS identified by the identification code accompanying the power exchange request. The maintenance staff is notified that the battery of the communication terminal CS needs to be replaced.

A driving state determination unit or the like for determining whether 12) is moving may be further provided.

[Operation: communication terminal (slave)]

Here, with reference to the flowchart of FIG. 6, an example of operation | movement of communication terminal CS2 which functions as a slave is demonstrated. In addition, here, like FIG. 2, it demonstrates communication terminal CS2 as a representative example, and abbreviate | omits description of communication terminal CS1 which operates similarly.

First, the input unit 102 receives an input of measurement data indicating a gal value measured by the acceleration sensor S2 at each preset detection period (step ST1). The input measurement data is written / stored in the storage unit 103.

Subsequently, when the new measurement data is stored in the storage unit 103, the detection cycle switching unit 104 reads out the new measurement data from the storage unit 103, and indicates that the new measurement data is represented by the read measurement data. It is determined whether or not the gal) value is equal to or greater than the first threshold value (step ST2). In addition, as described above, the first threshold value is a value set as an index for determining whether to change the detection period to a longer period or a shorter period than the current period.

As a result of the processing of step ST2 described above, when it is determined that the gal value represented by the measurement data is less than the first threshold value (NO in step ST2), the detection cycle switching unit 104 is similar to the present time. It is determined whether or not input of measurement data indicating a gal value determined as less than the first threshold value has been continuously received for a first time from the past to the present (step ST3). As a result of this processing, when it is determined that the input of the above-described measurement data is not continuous for the first time (NO in step ST3), the series of operations here is terminated, and the communication terminal CS2 detects the next. Until the period comes, that is, until there is an input of the next measurement data from the acceleration sensor S2, the standby state is reached. In addition, a 1st time is generally set to the time (for example, 10 minutes) in which an earthquake is considered to have subsided including aftershocks at the time of an earthquake.

On the other hand, when it is determined that the input of the measurement data has been continued for the first time as a result of the above-described process of step ST3 (YES in step ST3), the detection period switching unit 104 is accompanied by an earthquake or an earthquake. It is considered that the aftershock is unlikely to be detected, and the detection period for accepting the input of the measurement data from the acceleration sensor S2 is changed to a detection period longer than the present time (step ST4), and the series of operations here is terminated and communication is performed. The terminal CS2 enters the standby state until the next detection period comes, that is, until the next measurement data is input from the acceleration sensor S2.

As a result of the processing of step ST2 described above, when it is determined that the gal value represented by the measurement data is equal to or greater than the first threshold value (YES in step ST2), the detection period switching unit 104 detects an earthquake, It is considered that the aftershocks associated with the earthquake are likely to be detected, and the detection period for accepting input of measurement data from the acceleration sensor S2 is changed to a detection period shorter than the present time (step ST5).

Next, the power supply determination unit 105 is a result of the processing of the above-described step ST2 by the detection cycle switching unit 104, and the result that the gal value represented by the measurement data is equal to or greater than the first threshold value. When receiving, outputs a power-up command to the power supply control unit 101. The power supply control unit 101 starts to supply power to the communication control unit 107 in accordance with a power-on command from the power supply determination unit 105 (step ST6).

Subsequently, the operation permission determination unit 107a included in the communication control unit 107 reads out the latest measurement data stored in the storage unit 103 (in other words, the first threshold value or more in the process of Step ST2). The measurement data indicating the gal value determined to be read is read), and it is determined whether the gal value represented by the read measurement data is equal to or greater than the second threshold value (step ST7). In addition, although demonstrated previously, the 2nd threshold value is an earthquake-proof reference value set based on the strength limit of the guide rails 14c and 14d for the counterweight 13.

As a result of the processing of step ST7 described above, when it is determined that the gal value represented by the measurement data is less than the second threshold, that is, the gal value is greater than or equal to the first threshold and less than the second threshold. (NO in step ST7), the operation permission determination part 107a judges that it is unlikely that the guide rail 14c, 14d for the counterweight 13 had a damage or a problem, and measured the gal value. The second signal indicating that it is less than the earthquake-resistant reference value is transmitted to the communication terminal CM functioning as a master via the antenna A2 (step ST8), and the processing proceeds to step ST10 described later.

As a result of the process of step ST7 described above, when it is determined that the gal value represented by the measurement data is equal to or greater than the second threshold value (YES in step ST7), the operation permission determination unit 107a determines the counter weight ( 13) The first, which indicates that damage or a problem (for example, the guide rail is bent) has occurred in the guide rails 14c and 14d for use, and that the measured gal value is equal to or greater than the earthquake-resistant reference value. The signal is transmitted to the communication terminal CM functioning as a master via the antenna A2 (step ST9).

Next, the driving permission determination unit 107a determines whether or not an acknowledgment indicating that the first or second signal has been normally received by the communication terminal CM has been received (step ST10). As a result of this processing, when it is determined that the acknowledgment from the communication terminal CM has been received (YES in step ST10), the power supply control unit 101 stops supplying power to the communication control unit 107 ( Step ST11), the series of operations here are terminated, and the communication terminal CS2 is in a standby state until the next detection period comes, that is, until the next measurement data is input from the acceleration sensor S2.

On the other hand, when it is determined that the acknowledgment from the communication terminal CM has not been received (no reception) as a result of the above-described processing of step ST10 (NO in step ST10), the operation permission determining unit 107a is the first. Or, it is determined whether a predetermined time has elapsed since the transmission of the second signal (step ST12). In addition, it is assumed that the elapsed time after transmitting the first signal or the second signal is counted by an internal clock (not shown) provided in the communication terminal CS2. As a result of this process, when it is determined that the predetermined time has elapsed (YES in step ST12), the process of step ST11 described above is executed, and the communication terminal CS2 does not receive the acknowledgment and performs a series of operations here. Quit. Thereafter, the communication terminal CS2 enters the standby state until the next detection period comes, that is, until the next measurement data is input from the acceleration sensor S2.

When it is determined that the predetermined time has not elapsed as a result of the above-described process of step ST12 (NO in step ST12), the operation permission determination unit 107a sends the first or second signal via the communication terminal A2. After retransmitting to CM (step ST13), the process of said step ST10 is performed again.

According to the series of operations described above, the communication terminal CS2 supplies power to the communication control unit 107 only when the gal value measured by the acceleration sensor S2 is equal to or greater than the first threshold value, thereby saving energy. Therefore, it becomes possible to prolong the life of a battery or a battery provided independently. In addition, when the gal value measured by the acceleration sensor S2 is less than the first threshold value continuously for the first time, the communication terminal CS2 changes the detection period to be longer than the present time, so that the measurement data is input from the acceleration sensor S2. It is possible to reduce the number of times to receive the. That is, since the number of times of the above-described processing of step ST1 and the processing associated with this is reduced, it is energy-saving and it is possible to prolong the life of a battery or a battery provided independently.

[Operation: communication terminal (master)]

Next, with reference to the flowchart of FIG. 7, an example of operation | movement of the communication terminal CM which functions as a master is demonstrated.

First, the communication control part 202 determines whether the signal transmitted from the communication terminal CS, specifically, the 1st or 2nd signal was received with an identification code (step ST21). As a result of this process, when it is determined that no signal from the communication terminal CS has been received (NO in step ST21), the process of step ST21 is executed again.

On the other hand, when it is determined that the signal from the communication terminal CS has been received as a result of the above-described process of step ST21 (YES in step ST21), the communication control unit 202 transmits the received signal together with the identification code to the reply control unit ( 203 and output unit 204 (step ST22).

When the reply control unit 203 receives the input of the first or second signal output from the communication control unit 202, the acknowledgment for transmitting that the signal has been normally received is identified by the accompanying identification code. The communication control unit 202 is instructed to return to the communication terminal CS. The communication control unit 202 transmits the acknowledgment for the communication terminal CS through the antenna A1 in accordance with an instruction from the reply control unit 203 (step ST23).

Then, when the output part 204 receives the input of the 1st or 2nd signal output from the communication control part 202, it outputs the signal to the elevator control board 11 (step ST24), and here Terminates a series of operations.

[Operation regarding life and death monitoring: communication terminal (slave)]

Next, with reference to the flowchart of FIG. 8, an example of operation | movement regarding the life and death monitoring of communication terminal CS2 which functions as a slave is demonstrated. 2 and 6, communication terminal CS2 is taken as a representative example and description of communication terminal CS1 which operates similarly is abbreviate | omitted here.

First, the input unit 102 receives an input of measurement data indicating a gal value measured by the acceleration sensor S2 at each preset detection period (step ST31). The input measurement data is written / stored in the storage unit 103.

Subsequently, the input unit 102 has a gal value represented by the input measurement data that exceeds the gal value (maximum value) indicated by the maximum measurement data stored in the storage unit 103. It is determined whether or not it is (Step ST32). As a result of this processing, when it is determined that the current gal value has not exceeded the maximum value (NO in step ST32), the processing of step ST34 described later is executed.

On the other hand, when it is determined that the current gal value exceeds the maximum value as a result of the above-described process of step ST32 (YES in step ST32), the input unit 102 is stored in the storage unit 103. The value of the maximum measurement data is updated to this gal value (step ST33).

Next, the power supply determination unit 105 determines whether or not the second time ("second time" = "constant period") has elapsed since the last fixed period ends (step ST34). In addition, the elapsed time after the last fixed period ends is assumed to be counted by an internal clock (not shown) provided in communication terminal CS2. As a result of this process, when it is determined that the second time has not elapsed (NO in step ST34), the series of operations here are terminated, and the communication terminal CS2 has the next detection period or the second time has elapsed. Until it goes to sleep.

On the other hand, when it is determined that the second time has elapsed as a result of the above-described process of step ST34 (YES in step ST34), the power supply determination unit 105 outputs a power-on command to the power supply control unit 101. do. When the power supply control unit 101 receives the power-on command, the power supply control unit 101 starts to supply power to the communication control unit 107 in accordance with the power-on command (step ST35).

Subsequently, the periodic period reporting unit 107b included in the communication control unit 107 reads out the maximum measurement data stored in the storage unit 103, and stores the maximum measurement data together with the identification code of the communication terminal CS2. Transmission is performed to the communication terminal CM via the antenna A2 (step ST36).

After that, the periodic cycle reporter 107b resets the maximum measurement data stored in the storage unit 103 (step ST37), and the power supply control unit 101 supplies power to the communication control unit 107. It stops (step ST38), and complete | finishes a series of operation | movement here, and communication terminal CS2 becomes a standby state until the next detection period comes or the 2nd time elapses.

[Action regarding life and death monitoring: communication terminal (master)]

With reference to the flowchart of FIG. 9, an example of operation | movement regarding life and death monitoring of the communication terminal CM which functions as a master is demonstrated.

First, the output unit 204 determines the presence or absence of input of the maximum measurement data (in other words, the maximum measurement data transmitted from the communication terminal CS every fixed period) output from the communication control unit 202 every fixed period ( Step ST41). As a result of this processing, when it is determined that there is no input of the maximum measurement data (NO in step ST41), the communication terminal CM ends the series of operations here.

On the other hand, when it is determined that there is an input of the maximum measurement data as a result of the processing of step ST41 described above (YES in step ST41), the output unit 204 operates the communication terminal CS and its own terminal CM normally. The life and death signal indicating the output is output to the elevator control board 11 (step ST42).

Next, the output unit 204 determines whether or not the gal value represented by the maximum measurement data that has received the input is equal to or greater than the third threshold value (step ST43). As a result of this process, when it is determined that the gal value represented by the maximum measurement data is equal to or greater than the third threshold value (YES in step ST43), the output unit 204 is connected to the communication terminal CS. After the abnormality has not occurred in the sensor S, that is, the acceleration sensor S is determined to be operating normally (step ST44), the process of step ST46 described later is executed.

On the other hand, when it is determined that the gal value represented by the maximum measurement data is less than the third threshold value (NO in step ST43) as a result of the processing in step ST43 described above, the output unit 204 communicates with the communication terminal. After determining that an abnormality has occurred in the acceleration sensor S connected to the CS (in other words, the acceleration sensor S is likely to be stopped) (step ST45), the processing of step ST46 described later is executed.

Then, the output part 204 receives the result of the process of step ST44 or ST45, outputs the status signal which shows the present state of the acceleration sensor S to the elevator control board 11 (step ST46), Terminate the series of actions.

[Operation: elevator control device]

In addition, with reference to the flowchart of FIG. 10, an example of operation | movement of the elevator control apparatus 10 is demonstrated.

First, the elevator control apparatus 10 is based on the input from the various sensors which are not shown in the upper machine room or the hoistway, At least one of a gal, gal, gal and gal wave. It is determined whether is detected (step ST51). Further, gal, gal, gal and P waves are all indicators for determining whether an earthquake has occurred. Gal, gal and gal are detected by the S-wave sensor, and gal is detected when an earthquake of 200 [Gal] or more is detected, for example, in a building of 60 m or less in height. Is detected. Gal is detected when an earthquake of 150 [Gal] or more and less than 200 [Gal] is detected in the building, and gale is 80 [Gal] or more and less than 150 [Gal] in the building. It is detected when an earthquake is detected. In addition, P wave (initial fine motion) is detected by a P wave sensor.

As a result of the processing of step ST51 described above, when it is determined that none of the depleted gal, degal gal, extra gal and P waves are detected (NO in step ST51), the elevator control device 10 ) Executes the process of step ST79 described later, and ends the series of operations here.

On the other hand, when it is determined that at least one of gal, gal, gal, and P waves has been detected as a result of the above processing of step ST51 (YES in step ST51), the elevator control device 10 determines whether the boarding car 12 is moving (step ST52). In addition, the determination of whether the boarding car 12 is moving is used, for example, the result of the determination by the driving state determination part which is not shown in the driving control part 11b in the elevator control board 11, etc. are used.

As a result of the processing of step ST52 described above, when it is determined that the boarding car 12 is not moving, that is, being stopped (NO in step ST52), the elevator control device 10 stops the boarding car 12. The process of step ST68 mentioned later is performed as it is, rest | stopping to the layer (step ST53).

On the other hand, when it is determined that the boarding car 12 is in motion (YES in step ST52) as a result of the processing of step ST52 described above, the elevator control device 10 determines that the boarding car 12 is within a predetermined time (Yes). For example, it is judged whether or not it is possible to land on the floor closest to 10 seconds) (step ST54). In addition, in determining whether the boarding car 12 is able to land on the nearest floor within a predetermined time, information indicating the current moving speed of the boarding car 12, information indicating the current position of the boarding car 12, and the current position Information indicative of the distance from to the nearest floor is used.

As a result of the process of step ST54 described above, when it is determined that the boarding car 12 is able to land on the nearest floor within a predetermined time (YES in step ST54), the elevator control device 10 receives the boarding car 12. After implanting to the nearest layer (step ST55), the process of step ST68 mentioned later is performed. On the other hand, when it is determined that the boarding car 12 cannot land on the nearest floor within a predetermined time as a result of the processing of step ST54 described above (NO in step ST54), the elevator control device 10 receives the boarding car ( 12) is immediately stopped (step ST56).

Subsequently, the elevator control apparatus 10 determines whether the boarding car 12 stopped between two floors (floor) (step ST57). In addition, information which shows the current position of the boarding car 12 detected by the position control part 11c in the elevator control board 11, etc. are used for the determination of whether the boarding car 12 was stopped between floors. do.

As a result of the process of step ST57 described above, when it is determined that the boarding car 12 has not stopped between floors, that is, it is possible to accidentally land on the nearest floor (NO in step ST57), the process of step ST68 described later Is executed. On the other hand, when it is determined that the boarding car 12 has stopped between floors as a result of the processing of step ST57 described above (YES in step ST57), the elevator control device 10 is depleted (gal) and depleted (gal). It is determined whether or not both the gal and the P wave are not detected (step ST58).

In addition, when the result of this processing is that at least one of the depleted gal, the depleted gal, the depleted gal and the P wave has been detected, i.e., determined not to be detected (NO in step ST58), The process of step ST58 is repeatedly executed until all of the depleted gal, the depleted gal, the depleted gal and the P wave are not detected. On the other hand, when it is determined that all of the depleted gal, the depressed gal, the depressed gal and the P wave are not detected as a result of the above-described process of step ST58 (YES in step ST58), the elevator control device ( 10) determines whether depletion gal was detected in the process of step ST51 described above (step ST59).

When it is determined that depletion (gal) has not been detected as a result of the above-described process of step ST59 (NO in step ST59), the elevator control device 10 causes damage or problems to the various devices constituting the elevator system. After the boarding car 12 is moved in the direction in which the boarding car 12 and the counterweight 13 are separated from each other, and the boarding car 12 is placed on the nearest floor (step ST60), The process of step ST68 described later is executed.

On the other hand, when it is determined that depletion (gal) has been detected as a result of the process of step ST59 described above (YES in step ST59), the elevator control device 10 checks whether the elevator system is equipped with a low speed switch during the earthquake. It is judged whether or not (step ST61). In addition, the information regarding the presence or absence of a low speed switch at the time of an earthquake is preliminarily stored in the memory etc. which are not shown in the elevator control apparatus 10. FIG.

As a result of this process, when it is determined that the low speed switch is not attached at the time of the earthquake (NO at step ST61), the elevator control device 10 determines whether the first signal has been output from the communication terminal CM. More specifically, the elevator control apparatus 10 receives input of at least one of the first signal with the identification code of the communication terminal CS1 and the first signal with the identification code of the communication terminal CS2 from the communication terminal CM. It is judged whether or not it has been received (step ST62).

As a result of the process of step ST62 described above, when it is determined that the input of at least one first signal output from the communication terminal CM has been accepted (YES in step ST62), the elevator control device 10 receives the first The boarding vehicle 12 and / or the guide rail 14 supporting the counterweight 13 installed with the communication terminal CS identified by the identification code attached to the signal is likely to be damaged or have a problem. After stopping the car 12 from landing on the nearest floor (step ST63), the process of step ST70 described later is executed.

On the other hand, when it is determined that the input of the first signal from the communication terminal CM has not been accepted as a result of the above-described process of step ST62 (NO in step ST62), the elevator control device 10 constitutes the present elevator system. It is considered that the damage or the problem is unlikely to occur in a variety of devices, move the boarding car 12 in the direction in which the boarding car 12 and the counter weight 13 is separated, the boarding car 12 to the nearest floor After implantation (step ST64), the process of step ST68 described later is executed.

As a result of the process of step ST61 described above, when it is determined that the low speed switch is attached at the time of an earthquake (YES in step ST61), the elevator control device 10 determines that the low speed switch at the time of the earthquake and the vehicle 12 It is determined whether the door closing button arranged on the operation panel has been operated at the same time (step ST65). In addition, the information about the operation panel operated by the passenger, etc. output from the car control apparatus 21 is used for the determination of whether the low speed switch and the door closing button were operated simultaneously during an earthquake.

As a result of this processing, when it is determined that the low speed switch and the door closing button at the time of earthquake are not operated at the same time (NO at step ST65), the step ST65 is operated until the low speed switch and the door closing button at the time of earthquake are operated at the same time. The process is executed repeatedly. In this case, for example, an announce that the low speed switch and the door closing button can be operated simultaneously during an earthquake may be released from a speaker (not shown) in the boarding car 12.

As a result of the processing of step ST65 described above, when it is determined that the low speed switch and the door closing button at the time of earthquake are operated simultaneously (YES in step ST65), the elevator control device 10 determines that the low speed switch and the door closing button at the time of earthquake are While being pushed down, the boarding car 12 is moved at a low speed in the direction in which the boarding car 12 and the counter weight 13 are separated (step ST66). The elevator control apparatus 10 determines whether the boarding car 12 has landed on the nearest floor (step ST67). As a result of this process, when it is determined that the boarding car 12 has not yet reached the nearest floor (NO in step ST67), the above-described processes of steps ST65 and ST66 are executed again.

On the other hand, when it is determined that the boarding car 12 has landed on the nearest floor as a result of the above-described process of step ST67 (YES in step ST67), the elevator control device 10 opens the door of the boarding car 12. When the door is opened for a predetermined time (step ST68), and the passenger car 12 has a passenger, the passenger gets off.

The processes of steps ST51 to ST68 described above are a series of processes until the boarding car 12 is placed on the nearest floor when an earthquake occurs and the passengers get off. Subsequent processes become a series of processes from when the passenger gets off, until the boarding car 12 is restored.

First, after the process of step ST68 described above, the elevator control device 10 is connected to the acceleration sensors S1 and S2, respectively, and is included in the communication terminals CS1 and CS2 and the elevator control device 10 functioning as slaves. It is determined whether or not an abnormality has occurred in the communication terminal CM functioning as the master (step ST69). In addition, determination of whether abnormality has occurred in communication terminal CS1, CS2, and communication terminal CM is determined based on the result of the determination by the terminal abnormality determination part 301. FIG.

As a result of the process of step ST69 described above, when there is no input of the life and death signal from the communication terminal CM, and it is determined that an abnormality has occurred in any communication terminal (YES in step ST69), the elevator control device 10 Prohibits the automatic diagnostic operation for restoring the boarding car 12, and after putting the boarding car 12 in the driving stop state (step ST70), the process of step ST78 described later is executed.

On the other hand, when it is determined that the life and death signal from the communication terminal CM has been input as a result of the process of step ST69 described above and no abnormality has occurred in any communication terminal (NO in step ST69), the elevator control device 10 Determines whether or not an abnormality has occurred in the acceleration sensors S1 and S2 (step ST71). In addition, the determination of whether or not an abnormality has occurred in the acceleration sensors S1 and S2 is determined based on the result of the determination by the sensor abnormality determination unit 302 and the detection by the position control unit 11C.

As a result of the process of step ST71 described above, when it is determined that abnormality has occurred in at least one of the acceleration sensors S1 and S2 (YES in step ST71), the process of step ST70 is executed. On the other hand, when it is determined that no abnormality has occurred in the acceleration sensors S1 and S2 as a result of the processing of the above-described step ST71 (NO in step ST71), the elevator control device 10 is provided with an identification code of the communication terminal CS1. It is determined whether at least one of the input of the first signal and the first signal to which the identification code of the communication terminal CS2 has been received has been accepted (step ST72). As a result of this processing, when it is determined that the input of at least one first signal is accepted (YES in step ST72), the elevator control device 10 identifies by the identification code attached to the first signal. It is considered that there is a high possibility that damage or a problem has occurred in the guide car 14 supporting the boarding car 12 and / or the counterweight 13 on which the communication terminal CS is installed, and the process of step ST70 described above is executed.

On the other hand, when it is determined that the input of the first signal has not been received as a result of the processing of step ST72 described above, that is, the input of the second signal to which the identification codes of the communication terminals CS1 and CS2 has been accepted (" "", The elevator control apparatus 10 determines whether depletion gal or gal was detected in the process of step ST51 (step ST73). As a result of this processing, when it is determined that neither of the gal or the gal is detected (NO in step ST73), the process of step ST79 described later is executed.

As a result of the processing of step ST73 described above, when it is determined that either depletion gal or gal is detected (YES in step ST73), the elevator control device 10 depletes gal or depletion ( It is determined whether or not the third time has elapsed since gal) is detected (step ST74). In addition, 3rd time is set to the time by which the shaking of the rope at the time of an earthquake is considered to have subsided. As a result of this process, when it is determined that the third time has not elapsed (NO in step ST74), the process of step ST74 is repeatedly executed until the third time elapses.

On the other hand, when it is determined that the third time has elapsed as a result of the above-described process of step ST74 (YES in step ST74), the elevator control device 10 starts the automatic diagnosis operation during the earthquake of the boarding car 12. (Step ST75).

Subsequently, the elevator control apparatus 10 determines whether or not the automatic diagnosis operation at the time of earthquake is completed (step ST76). Incidentally, whether or not the automatic diagnosis operation at the time of earthquake is finished is determined based on whether or not the input of the end signal output at the end of the diagnostic operation is accepted, for example. As a result of this process, when it is determined that the earthquake automatic diagnosis operation has not yet finished (NO in step ST76), the process of step ST76 is repeatedly executed until the earthquake automatic diagnosis operation ends.

When it is determined that the automatic diagnosis at the time of earthquake has ended as a result of the above-described process of step ST76 (YES in step ST76), the elevator control device 10 temporarily restores the boarding car 12, and after that, The temporary recovery operation is performed (step ST77).

The maintenance worker needs to go to the spot and perform the inspection work even when the boarding car 12 is performing the temporary recovery operation. For this reason, the inspection work by a maintenance worker is started. When the inspection work by the maintenance worker is started, the elevator control apparatus 10 determines whether the inspection work by the maintenance worker is complete | finished (step ST78).

As a result of this process, when it is determined that the inspection work has not yet finished (NO in step ST78), the process of step ST78 is repeatedly executed until it is determined that the inspection work by the maintenance worker is finished.

On the other hand, when it is determined that the inspection work is finished (YES in step ST78), the elevator control device 10 completely recovers the boarding car 12, and then performs normal operation (step ST79). Terminate a series of operations on.

The elevator system which concerns on one Embodiment is provided with the communication terminal CS2 which functions as a slave, and this communication terminal CS2 is equipped with the original power supply apparatus. According to this, it becomes possible to provide communication terminal CS2 in the counter weight 13, without forming a new power supply facility (power supply cord) etc. in the counter weight 13. As shown in FIG.

In addition, the communication terminal CS2 communicates with another communication terminal (specifically, the communication terminal CM) only when the gal value measured by the acceleration sensor S2 connected by wire is equal to or greater than the first threshold value. Since the power is supplied to the power supply), it is energy-saving and it is possible to extend the life of the power supply device that is provided independently.

In addition, when the gal value measured by the acceleration sensor S2 is less than the first threshold value continuously for the first time, the communication terminal CS2 is changed to make the detection period for receiving the measurement data input from the acceleration sensor S2 longer than the present time. Therefore, it becomes possible to reduce the number of times of receiving input of the said measurement data. That is, since the power consumption at the time of receiving input of measurement data can be reduced, it is energy saving and can extend the lifetime of the power supply device provided independently.

In addition, as described above, since the communication terminal CS2 has various functions for prolonging the life of the power supply device, it is possible to reduce the number of times a maintenance worker replaces the power supply device, and to reduce the burden on the maintenance worker. It is possible.

According to one embodiment described above, it becomes possible to provide an elevator system which can transmit the output from the sensor provided in the counter weight to the elevator control device without providing a new power supply device in the counter weight.

Moreover, in this elevator system, since the various processes shown in FIG. 10 and FIG. 11 can be performed, when an earthquake occurs, it is possible to implement | achieve the elevator system which can be restored quickly after fully considering safety.

In this embodiment, as shown in FIG. 1, the communication terminal CS1 is provided in the boarding car 12, the communication terminal CS2 is provided in the counterweight 13, and it communicates with the communication terminals CS1 and CS2 in the upper machine room. Although the case where possible communication terminal CM is provided was illustrated, the installation layout of a communication terminal, especially the installation position of communication terminal CM is not limited to this. Hereinafter, with reference to FIGS. 12-14, the installation layout different from FIG. 1 is demonstrated.

[First Modification]

FIG. 12: is a figure which shows the schematic structural example of the elevator system which concerns on the 1st modified example of this embodiment. The elevator system shown in FIG. 12 does not install the communication terminal CM which functions as a master in the upper machine room, but is provided on the boarding car 12 instead of the communication terminal CS1, and the elevator system shown in FIG. Different. The communication terminal CM is connected by wire with the acceleration sensor S1 provided on the boarding car 12.

In this case, although the wiring installation 100 for connecting the communication terminal CM and the elevator control apparatus 10 is newly needed, the number of communication terminal CSs functioning as slaves can be reduced by one, and the cost can be reduced. It becomes possible. In this case, however, at least the functional units corresponding to the input unit 102, the storage unit 103, the driving permission determination unit 107a, and the periodic cycle reporting unit 107b included in the communication terminal CS are mounted on the communication terminal CM. There is a need. The communication terminal CM may further be equipped with a functional unit corresponding to the detection period switching unit 104.

FIG. 13: is a figure which shows schematic structural example of the elevator system which concerns on the 2nd modified example of this embodiment. The elevator system shown in FIG. 13 is similar to the configuration of FIG. 12 in that the communication terminal CM serving as a master is provided on the boarding car 12 instead of the communication terminal CS1 in the upper machine room. It is different from the elevator system shown in FIG. In addition, since the communication terminal CM is not directly connected with the elevator control apparatus 10, the communication terminal CM is indirectly connected with the elevator control apparatus 10 via the car control apparatus 21, FIG. It is also different from the elevator system shown in FIG.

In this case, the number of communication terminals CS functioning as slaves is reduced by one, and a new wiring facility 100 for connecting the communication terminal CM and the elevator control apparatus 10 is also unnecessary. It becomes possible. In more detail, although the wiring installation 200 for connecting the communication terminal CM and the car control apparatus 21 is newly needed, it becomes a simple wiring installation compared with the wiring installation 100 extended to the upper machine room. Therefore, the cost can be reduced. Even in this case, however, the communication terminal CM includes at least functional parts corresponding to the input unit 102, the storage unit 103, the driving permission determination unit 107a, and the periodic cycle reporting unit 107b included in the communication terminal CS. It needs to be mounted. Also in this case, the communication terminal CM may further be equipped with a functional unit corresponding to the detection period switching unit 104.

According to this modification, similar to the first modification, it is possible to obtain the same effects as in the above-described embodiment.

It differs from the elevator system shown in FIG. 1 in that the sensor S3 is provided.

Acceleration sensor S3 is a sensor for detecting (measuring) the shaking of the upper machine room.

In this case, since the acceleration sensor S3 is increased as a new facility, although it costs more compared with the elevator system shown in FIG. 1, based on the gal value measured by the acceleration sensor S3, the main sheave 18a, Since it becomes possible to determine whether there is no damage or a problem with the flipping sheave 18b and the motor 19, it becomes possible to ensure more safety. Also in this case, the communication terminal CM includes at least functional units corresponding to the input unit 102, the storage unit 103, the driving permission determination unit 107a, and the periodic cycle reporting unit 107b included in the communication terminal CS. It needs to be mounted. Also in this case, the communication terminal CM may further be equipped with a functional unit corresponding to the detection period switching unit 104.

According to this modification, similarly to the first and second modifications, the same effects as those of the above-described embodiments can be obtained, and the determination of whether or not the automatic diagnostic operation for performing the temporary recovery operation may be performed with higher precision is made. It becomes possible to do it on the road.

In addition, in this embodiment, the case where the sensor connected to communication terminals CS1 and CS2 by wire is only an acceleration sensor was demonstrated, However, other sensors, such as an audio sensor, are further wired connection to communication terminals CS1 and CS2, for example.
