It is configured to monitor the operating status.

To show a specific example, the elevator monitoring device 1 includes an interface device 11, a monitoring control device 15, a communication communication device 13, and a line device 14. The interface device 11 is configured to receive an operation signal output from the elevator control panel 21 in a unique output arrangement, sort the operation signals into a monitoring arrangement indicating a predetermined operation content, and output the operation signal. The monitoring control device 15 is configured to monitor the operation status of the elevator 2 based on the operation signal of the monitoring array output from the interface device 11.

Here, the "elevator 2" includes an elevator and an escalator. Elevators include home elevators, stair lifts, and step-eliminating machines. In this embodiment, a basket 22 provided with an intercom 221 and an elevator 2 having a hoisting machine for raising and lowering the basket 22 will be described. The "operation content" indicates individual operating elements of the elevator 2, for example, ascending, descending, starting traveling, stopping traveling, opening the door, closing the door, existing on the first floor, existing on the second floor, existing on the third floor, and the like. be. The "operation signal" is either "1" indicating that the operation content is in the operating state or the detection state, or "0" indicating that the operation content is in the stopped state or the undetected state. For example, if the operation signal of "rise", which is the operation content, is "1", it indicates that the elevator 2 is in the operating state of climbing, and if the operation signal of "rise" is "0", the elevator 2 is in the operating state. Indicates that the operating state is stopped.

The “output array” is an array in which the elevator control panel 21 outputs operation signals in a predetermined order. The "output array" is a parallel form in which a plurality of operation signals are associated with a plurality of output terminals and the operation signals are output from each output terminal, and a plurality of operation signals are output one by one in order from a single output terminal. There are two types, the series form. For example, when there are operation contents of ascending, descending, traveling start, and traveling stop, the first operation signal means "ascending", the second operation signal means "descending", and the third. The fourth operation signal means "start of running", and the fourth operation signal means "stop running". When the output arrangement is in parallel form, each output signal is output from the first terminal, the second terminal, the third terminal, and the fourth terminal. On the other hand, when the output arrangement is in series form, the first output signal, the second output signal, the third output signal, and the fourth output signal are output in order from a single terminal. In the parallel form "output array", a plurality of operation signals may be independently output at arbitrary timings, or a plurality of operation signals may be periodically output at the same time. On the other hand, in the series form "output array", a group of a plurality of operation signals is output at predetermined time intervals.

The "operation status" indicates the overall operation state of the operation content, and is, for example, the operation state in which the elevator 2 stopped on the second floor starts traveling and rises. At this time, if the elevator 2 is in an operating state where the elevator 2 rises while the traveling is stopped, it can be determined that an abnormality has occurred in at least one of the elevator 2 and the elevator control panel 21.

A specific example of the interface device 11 is shown with reference to FIG. The interface device 11 has an operation signal input unit 111 that can be connected to the elevator control panel 21 and input an operation signal of the output arrangement. The operation signal input unit 111 has a connector associated with the output form of the elevator control panel 21. For example, if the outputs of the elevator control panel 21 are in parallel, the operation signal input unit 111 has a connector having a plurality of input terminals into which a plurality of operation signals are input.

The output unit 116 is capable of outputting various data including model data to the outside. Examples of the output form of the output unit 116 include a display device that displays data, a speaker that outputs data by voice, and the like. The output unit 116 may have a plurality of output forms.

The communication unit 117 is configured to enable data communication with an external device by wire or wirelessly. The communication unit 117 has a function capable of communicating with the communication device 53 of the monitoring center shown in FIG. 1 and a function capable of communicating with the mobile communication device. Examples of mobile communication devices include mobile personal computers having a communication function. When the communication unit 117 has a function capable of communicating with the portable communication device, the work can be facilitated by outputting the operation status of the elevator 2 by voice or display in the portable communication device of the worker who maintains the elevator 2. It will be possible to do it.

The GPS unit 118 is a GPS device that wirelessly transmits position information to the outside. The GPS unit 118 makes it possible to detect the existing position, the moving width, and the moving distance by outputting the position information of the place where the elevator monitoring device 1 is installed. Further, the GPS unit 118 is connected so as to receive power supply from an auxiliary power supply device 119 composed of a secondary battery and a large-capacity capacitor. The auxiliary power supply device 119 is configured to output electric power to each part of the interface device 11 when the electric power from the external power source is cut off. As a result, the GPS unit 118 operates by supplying power from the external power supply and the auxiliary power supply device 119, and constantly transmits the position information. As a result, even if the elevator monitoring device 1 is stolen, the GPS unit 118 can continuously transmit the position information to detect the theft or the like based on the change in the position information, and the elevator monitoring device 1 exists. You can identify and find the location.

The output conversion unit 120 has a function of converting an information processing signal input via the signal bus 130 into a signal suitable for transmission to the monitoring control device 15. For example, when an operation signal indicating that "0" is 0 volt and "1" is 3 volt is input to the output converter 120, "0" is converted to 0 volt and "1" is converted to 12 volt voltage. Has the function of Further, when the monitoring control device 15 is designed to receive the operation signal in the series form, it has a function of outputting the operation signal in the parallel form as the operation signal in the series form.

The A / D conversion unit 121 has a function of quantizing an analog signal composed of a direct current or a direct current voltage and converting it into a digital signal. The A / D converter 121 is connected to the antennas 122a and 122b that receive electromagnetic waves. The antennas 122a and 122b convert electromagnetic waves output from the interface device 11, the monitoring control device 15, the elevator control panel 21, and the like into electric power. The electric power obtained from the antennas 122a and 122b is converted into a digital amount voltage value (electromagnetic wave data) by the A / D conversion unit 121, and is input to the calculation unit 114 and the storage unit 113. When the voltage value (power value) of the electromagnetic wave received by the antennas 122a and 122b is equal to or higher than a predetermined threshold value, the calculation unit 11 transmits an alarm signal indicating an abnormal state from the communication unit 117 to the monitoring center 5. It is configured to function as part 1144. As a result, when the interface device 11 oscillates in a resonance state due to deterioration of an electronic component such as a capacitor and an electromagnetic wave of a large voltage (electric power) is generated, the interface device 11 notifies the monitoring center 5 as an abnormal state, thereby causing the electronic circuit to oscillate. It makes it possible to perform maintenance before a major abnormality such as overheating occurs.

To show a specific example, the interface device 11 corresponds to the communication unit 117 connected to the database server storing the database of the sequence change data so as to be capable of data communication, and the model data input to the model data input unit 115. When the sequence change data is not stored in the storage unit 113, the database server is accessed via the communication unit 117, and the sequence change data corresponding to the model data is read out and stored in the storage unit 113. The sequence change data update unit 1143 And may have. According to the above configuration, when the model of the elevator control panel 21 to be connected is confirmed at the site, the necessary sequence change data is read from the database server and stored in the storage unit 113 in advance, thereby storing the storage unit 113 in advance. It is not necessary to suppress the database of the sequence change data to be stored in the storage unit to the minimum necessary, or to store the sequence change data in the storage unit 113 in advance.

(Interface device 11: Array setting table)
The array setting table and the array change table formed in the storage unit 113 will be described in detail.

The arrangement change table is a table for changing the output arrangement of the elevator control panel 21 whose model number is "C_0002" to the monitoring arrangement of the monitoring control device 15. As a result, even if the output array differs depending on the model number, the sequence change table can be processed by incorporating the operation signals of a plurality of models into one type of monitor control device 15 by changing to the monitor array of the monitor control device 15. It is possible to do.

More specifically, the sequence change table has an input field for storing the operation data of the output sequence and an output field for storing the operation data of the monitoring sequence. The input field has a sequence number column for storing the sequence number data, an operation content column for storing the operation content data, and an input signal field for storing the input signal data which is the operation signal output by the elevator control panel 21. ing. The sequence number data in the input field is associated with the operation content data and the input signal data. For example, the sequence number data of "IN_00" is associated with the operation content data of "rise" and the input signal data of "0". As a result, the input terminal specified by the array number of "IN_00" is input with an input signal (operation signal of the elevator control panel 21) indicating the operation content of "ascending", and is currently input. Since the signal is "0", it indicates that the basket 22 is stopped. In addition, the input terminal specified by the sequence number of "IN_04" is designed to input an output signal indicating the operation content of "door open", and at present, the output signal is "1". It indicates that the door of the basket 22 is in the open state.

On the other hand, the output columns include a sequence number column for storing the sequence number data, an operation content column for storing the operation content data, and an output signal column for storing the output signal data which is the operation signal output to the monitoring control device 15. have. The sequence number data in the output column is associated with the operation content data and the output signal data. For example, the sequence number data of "OUT_00" is associated with the operation content data of "door open" and the output signal data of "1". As a result, the output terminal specified by the sequence number of "OUT_00" is designed to output an output signal (operation signal to the monitoring control device 15) indicating the operation content of "door open". Since the output signal is "1", it indicates that the door of the basket 22 is in the open state. Further, the output terminal specified by the sequence number of "OUT_04" is designed to output an output signal indicating the operation content of the "first floor detection sensor", and at present, the output signal is "0". Therefore, it indicates that the basket 22 does not exist on the first floor.

The input conversion unit 151 has a function of converting the operation signal input to the operation signal input unit 160 into a data signal suitable for information (signal) processing in the monitoring control device 15. The conversion function is the same as that of the input conversion unit 112 in the interface device 11.

As a result, for example, the monitoring control device 15 is positioned by the GPS unit 157 continuing to transmit the position information when the elevator monitoring device 1 is stolen or moved even when the interface device 11 does not exist. Theft and the like can be detected based on the change in information, and the location of the elevator monitoring device 1 can be specified and searched for.

It is remembered that it occurred at 13 minutes and 25 seconds on the same date and time, which is "12 / 23_21: 13: 25". This makes it possible to monitor and reconfirm the operation of the basket 22 based on the data stored in the operation monitoring table. For example, in FIG. 6, after the door of the basket 22 closes at 13 minutes and 25 seconds, the car starts climbing, reaches the second floor at 13 minutes and 26 seconds, and stops running at 13 minutes and 53 seconds on the third floor.

The operation content data collection process (S2) captures the output signal (operation content) of the elevator control panel 21 input from the interface device 11, links it to the captured operation time, and stores the operation content in the storage form of the operation monitoring table. do.

The basket monitoring data collection process (S3) takes in the basket monitoring data input from various sensors installed in the basket 22, associates it with the captured operation time, and stores the basket monitoring data in the storage form of the basket monitoring table. Examples of the basket monitoring data include the temperature inside the basket, the acceleration inside the basket, the vibration level, the atmospheric pressure inside the basket, and the like.

The control panel monitoring data collection process (S4) receives the electromagnetic waves emitted from the elevator control panel 21 by the antenna 122a, and detects electromagnetic wave level data which is digital data of the voltage value and current value (power value) of the received electromagnetic waves. It is associated with the time data and stored, and the temperature data is associated with the detected time data and stored.

The monitoring device data collection process (S5) receives the electromagnetic waves emitted from the elevator monitoring device 1 (interface device 11, monitoring control device 15, communication communication device 13, line device 14, etc.) by the antenna 122b, and receives the received electromagnetic waves. The electromagnetic wave level data, which is digital data of the voltage value and the current value (power value), is stored in association with the detection time data, and the temperature data of the elevator monitoring device 1 is associated with the detection time data and stored.

The operation determination process (S6) determines whether the operation state is normal or abnormal based on the operation content data and the operation time data collected in the operation content data collection process (S2), and monitors the determination result. Send to center 5. For example, if the operation content of "rise, start running" is executed at the time of "door open", it is determined that the vehicle is in an abnormal state.

In the operating state determination process (S7), the operating state is normal or abnormal based on the car monitoring data (temperature in the car, acceleration in the car, vibration level, air pressure in the car, etc.) collected in the car monitoring data collection process (S3). It is determined which is the case, and the determination result is transmitted to the monitoring center 5. For example, a numerical range that is a normal range is set, and whether the operating state is normal or abnormal is determined based on whether or not the basket monitoring data exists within the normal range. To show a specific example, regarding the temperature inside the basket, the numerical range of the normal range is set from 15 degrees to 28 degrees, and the determination is made based on this numerical range and the temperature inside the basket.

The upload process (S8) transmits various data collected by the operation content data collection process (S2), the basket monitoring data collection process (S3), and the monitoring device data collection process (S5) to the monitoring center 5. The transmission to the monitoring center 5 may be performed at regular intervals or at a timing when a predetermined amount of data is reached.

(Interface processing)
An interface processing program executed by the interface device 11 will be described with reference to FIG. It is assumed that the monitoring control program is apparently executed by multitask control in which each process is processed in parallel.

The interface processing program is made executable by the arithmetic unit 114 (computer) of FIG. 2, and includes initial setting processing (S10), operation content data input processing (S20), array change processing (S30), and operation content. It has a data output process (S40) and an abnormality detection process (S50).

As shown in FIG. 11, the initial setting process (S10) determines whether or not the initial setting is completed (S101), and if the initial setting is completed (S101: YES), ends this process. .. On the other hand, if the initial setting is not completed (S101: NO), the input of the model number of the elevator control panel 21 is accepted (S102). When the model number is input, the sequence change data corresponding to the model number is searched from the sequence setting table (sequence change data) stored in advance in the storage unit 113 (S103).

If the sequence change data corresponding to the model number exists as a result of the search in S103 (S104: YES), the sequence change data associated with the model number is read out from the storage unit 113 (S109). Then, in order to prevent a third party from reading and diverting the sequence change data, after deleting the sequence change data in the memory except for the sequence change data associated with the model number (S110), this process is performed. To finish. On the other hand, if the sequence change data corresponding to the model number does not exist (S104: NO), the database server including the monitoring center server 51 and the cloud server 6 of the monitoring center 5 is accessed, and the sequence setting stored in this database server is accessed. The sequence change data corresponding to the model number is searched from the table (sequence change data) (S105).

After that, if the model number exists (S106: YES), S109 and S110 are executed, and then this process ends. On the other hand, if the model number does not exist (S106: NO), the array change data associated with the model number is created (S107). In the method of creating the arrangement change data, the output signal from the elevator control panel 21 is associated with the operation content when the elevator 2 is automatically or manually operated according to a predetermined procedure, and the monitoring control device 15 is shown in the figure. This is done by completing the sequence change table of 4. After that, the created sequence change data is registered in the database server (S108), S110 is executed, and then this process is terminated.

The operation content data input process (S20) receives the operation signal output from the elevator control panel 21, and in the input field of the arrangement change table of FIG. 4, the input signal data associated with the arrangement number of the output arrangement is set to "0". "Or" 1 ". For example, when the door of the basket 22 is open, the input signal data corresponding to the array number “IN_04” of the output array is set to “1”.

The sequence change process (S30) is a process of changing the input signal data stored in the input field of the sequence change table to the output signal data of the sequence number corresponding to the watch sequence of the monitor control device 15. For example, when the door of the basket 22 is opened and the input signal data corresponding to the array number "IN_04" of the output array is set to "1", the array number "OUT_00" which is the monitoring array of the elevator control panel 21 is set. The output signal data corresponding to "" is set to "1". The operation content data output process (S40) is a process of outputting an output signal composed of input signal data stored in the output column of the arrangement change table to the elevator control panel 21 in the output form of the monitoring array.

The abnormality detection process (S50) is a process of detecting an abnormality in the monitoring control device 15 or the elevator control panel 21 and notifying the monitoring center 5. As a specific example, as shown in FIG. 2, when the electromagnetic waves emitted from the monitoring control device 15 and the elevator control panel 21 and the like are received by the antennas 122a and 122b and converted into the reception voltage, the digital data of the reception voltage is obtained. Is stored in the storage unit 113 (S501). After that, the average value of the received voltage is calculated based on the received voltage data collected within a certain period, and is used as the average received voltage (S502). The average received voltage is compared with a threshold value indicating the boundary value of the presence or absence of abnormality (S503). If the average reception voltage is less than the threshold value (S503: NO), it is determined that there is no abnormality, and this process ends. On the other hand, when the average reception voltage is equal to or higher than the threshold value (S503: YES), it is determined that there is an abnormality, and after the abnormality signal is transmitted to the monitoring center 5 (S504), this process is terminated.

(Modification example of interface device 11)
In the above embodiment, the interface device 11 of FIG. 2 is an arrangement in which the arithmetic unit 114 executes an interface processing program to change the operation signal of the output array output from the elevator control panel 21 into the operation signal of the monitoring array. Although the configuration has been described as executing the change processing, the present invention is not limited to this, and the sequence change processing may be executed by the FPGA (Field Program Gate Array).

Explaining a specific example based on FIG. 13, the interface device 11A has an FPGA unit 125 which is an arrangement changing unit. The FPGA unit 125 is connected to the input conversion unit 112, the output conversion unit 120, and the signal bus 130, and is connected to each processing unit via the signal bus 130. The FPGA unit 125 has an FPGA (Field Programmable Gate Array) that forms a circuit configuration for changing the operation signal of the output array to the operation signal of the monitoring array based on the arrangement change data. Here, the "arrangement change data" is data for setting the FPGA so as to have a circuit configuration for executing the arrangement change process associated with the model of the elevator control panel 21.

As a result, the interface device 11A takes in the operation signal of the output arrangement output from the elevator control panel 21 into the FPGA unit 125 via the operation signal input unit 111 and the input conversion unit 112, and the FPGA unit 125 operates the monitoring arrangement. After changing to a signal, it is output to the monitoring control device 15 via the output conversion unit 120 and the operation signal output unit 123. The members having the same function as the interface device 11 of FIG. 2 are designated by the same member number, and the description thereof will be omitted.

The storage unit 113 stores an FPGA database that stores a plurality of sequence change data, an FPGA setting program for setting the FPGA unit 125 based on the sequence change data, and the like. It is preferable that the FPGA setting program executes a data erasure process (data erasure unit) for erasing the sequence change data from the storage unit 113 after the formation of the circuit configuration by the FPGA is completed. By having the data erasure process (data erasure unit), the interface device 11A can erase the sequence change data stored in the storage unit 113 and prevent leakage to the outside. As a result, the interface device 11A can ensure the confidentiality of the sequence change data even if a large amount of the sequence change data is stored in the storage unit 113 in advance.

(Interface device 11A: FPGA data table)
FIG. 14 shows an example of the FPGA data table in the interface device 11A. The data in the FPGA data table is a look-up table or the like associated with the model number of the elevator control panel 21, and is stored in the storage unit 113 of the interface device 11A. Here, the "look-up table" is a truth table for causing the FPGA to execute a predetermined process, and the FPGA is wired to a circuit configuration that executes the operation according to the operation defined in the truth table. ing.

More specifically, the FPGA data table has a control panel (model number) column for storing model number data and a lookup table column for storing lookup table data. "C_0001", "C_0002", and "C_0003" are stored as model number data in the control panel column, and "FPGA_C01", "FPGA_C02", and "FPGA_C03" are stored in the lookup table column. .. The model number data is associated with the look-up table data. For example, when the model number data "C_0001" is selected, the look-up table data "FPGA_C01" is selected.

In the case of the interface device 11A, the monitoring center 5 has an FPGA data table as a database. As a specific example, FIG. 15 shows an example of the FPGA data table in the monitoring center server 51 of the monitoring center 5. This FPGA data table stores all the data including the data of the FPGA data table of FIG. 13 stored in the interface device 11A. The structure of the data table is the same as that of the FPGA data table shown in FIG.

(Interface device 11A: Interface processing)

The initial setting process in the interface device 11A will be described with reference to FIG. First, it is determined whether or not to set the FPGA (S601). If the FPGA is not set (S601: NO), this process ends. On the other hand, when the FPGA is set (S601: YES), the input of the model number of the elevator control panel 21 is accepted (S602). When the model number is input, the FPGA data stored in advance in the storage unit 113 is searched (S603). If the model number is stored by the search (S604: YES), the lookup table associated with the model number is read out (S605), and the FPGA is set based on the lookup table (S610). After that, the FPGA data is deleted from the storage unit 113 (S611), and this process is completed.

On the other hand, if the model number is not stored in the storage unit 113 (S604: NO), a lookup table associated with the model number is created (S608), and the lookup table is stored in the monitoring center server 51 of the monitoring center 5. And register in the database server including the cloud server 6 (S609). After that, the FPGA is set based on the lookup table (S610), and after the FPGA data is deleted from the storage unit 113 (S611), this process is terminated.
