Description

Specification

Remote monitoring system

Technical field

The present invention relates to a remote monitoring system that monitors a property in a remote place with a monitoring center capability.

Background art

[0002] Conventionally, in order to grasp the effects of earthquakes on remotely monitored objects, appropriate locations of monitored objects (for example, the bottom of the pit in the elevator hoistway, the machine room above the hoistway, the hoistway wall, etc.) P wave seismic sensor and S wave seismic sensor are installed.

[0003] As shown in the conceptual diagram of FIG. 11, the P wave 101 is called a longitudinal wave or a dense wave, and is a small shock wave that first reaches the building 104 from the epicenter 102 due to ground collapse or the like through the rock 103. The S wave 105 is called a transverse wave and is a large shaking wave that travels through the rock mass 103 after the P wave arrives. The P wave has a slightly different force depending on the density and rigidity of the ground (a kind of stiffness). The speed of the P wave is said to be about 6 km per second, and the S wave is about 3.5 km per second. That is, the P wave travels nearly twice as fast as the S wave.

[0004] When a P wave is detected by a P wave seismic sensor, a conventional elevator control device switches to a control operation mode due to an earthquake, and operates each elevator in the control operation mode. After detecting the P wave, the elevator controller stops the operation of each elevator unit when the S wave is detected by the S wave seismic sensor within a predetermined time.

[0005] When the elevator control device detects the P wave and the S wave, the elevator control device transmits the P wave detection signal and the S wave detection signal to the monitoring device of the remote monitoring center through the communication line. Disclosure of the invention

[0006] In general, a monitoring center has a large number of monitored objects over a wide area under a maintenance contract.

(Property to be maintained) is monitored. For this reason, when an earthquake that is a wide-area disaster occurs, the P-wave seismic sensors and S-wave seismic sensors of a large number of monitored properties scattered over a wide area react simultaneously. Then, the P wave and S wave detection signals are sent to the monitoring center all at once from the elevator controller of each monitored property through the communication line. As a result, the monitoring center will be unable to communicate due to overcommunication load. [0007] When such a situation occurs, it is relatively far from the earthquake occurrence area! Signals generated in the area (for example, emergency call signals from the car, request signals from customers, etc.) are reported. However, since the communication line on the monitoring center side is punctured, these signals cannot be received. As a result, the entire remote monitoring system may be greatly affected, and it will be difficult to ensure the safety of the monitored property.

[0008] Therefore, an object of the present invention is to provide a remote monitoring system that can secure a communication line as much as possible and maintain monitoring performance even when an earthquake occurs.

[0009] According to one aspect of the present invention, an earthquake sensor that detects the first and second signals propagating with a time difference when an earthquake occurs, and the elevator when the first signal is detected by the earthquake sensor, A control operation start signal generating unit that sends a switching signal for starting the control operation mode to the operation control unit, and when the second signal is detected by the earthquake sensor, the elevator stop instruction signal is transmitted to the operation control unit. A monitoring target including a stop instruction signal generation unit to be transmitted to the control unit, and an earthquake detection signal transmission unit that transmits a detection signal of the earthquake sensor via a communication line when the second signal is detected. A remote monitoring system comprising: an earthquake detection control unit for a property; and a monitoring device connected to the communication line and receiving a detection signal of the earthquake sensor transmitted from the earthquake detection control unit. A system is provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0012] (First embodiment)

FIG. 1 is a block diagram showing an embodiment of a remote monitoring system according to the present invention.

[0013] In the remote monitoring system, a large number of monitored objects 1,... Scattered over a wide area and a monitoring device 2 in a monitoring center installed in a remote area are connected by a communication line 3. Here, the property to be monitored 1 means an elevator facility that performs regular or emergency maintenance management under a maintenance contract. Each monitored property 1, ... has an elevator control device 4 installed.

[0014] The elevator control device 4 includes an operation control unit 11 that controls the operation of each elevator (not shown) toward the target floor in response to a hall call and a car call, and a seismic detection control that detects the occurrence of an earthquake. Part 12.

[0015] The operation control unit 11 controls a power converter (not shown) according to the speed command, and drives and controls the hoisting machine 13 using AC power of variable voltage and frequency that can also obtain the power converter power. To do. A main rope (not shown) is wound around the hoisting machine 13, and a cage is suspended at one end of the main rope, and a balance! / Is suspended at the other end of the main rope. . The operation control unit 11 also includes a message data setting unit 14 when an earthquake occurs. The message data setting unit 14 stores message data for providing predetermined information to the elevator user.

On the other hand, a P-wave earthquake sensor 15 and an S-wave earthquake sensor 16 are connected to the earthquake detection control unit 12. These seismic sensors 15 and 16 are located at appropriate locations in the monitored property 1 (for example, the bottom of the pit in the hoistway, the machine room above the hoistway, the walls of the hoistway, and other appropriate locations in the building where the elevator is installed) ). [0017] The P-wave earthquake sensor 15 detects the first P wave (longitudinal wave) that also reaches the source force of the ground due to ground collapse, etc., and sends the detection signal to the earthquake detection control unit 12. The S-wave seismic sensor 16 detects an S-wave (transverse wave) accompanied by a large shaking transmitted through the rock after the arrival of the P-wave, and sends the detection signal to the earthquake detection control unit 12.

[0018] Based on the detection signals of the respective earthquake sensors 15 and 16, the earthquake detection control unit 12 sends an operation change instruction signal to the operation control unit 11 and sends only an S wave detection signal to the monitoring device 2. Send (described later).

[0019] When the monitoring device 2 receives the S wave detection signal transmitted from the earthquake detection control unit 12, ... of each monitored object 1, ..., the elevator stops for each monitored object 1 by S wave detection. It has the function of memorizing and displaying that it is in the middle.

FIG. 2 is a functional block diagram showing the internal configuration of the earthquake detection control unit 12.

[0021] The earthquake detection control unit 12 is provided with a CPU that executes predetermined control in accordance with predetermined program data. Functionally, the P wave level setting unit 121, the control operation start signal generation unit 122, the S wave level setting unit 123, the elevator stop instruction signal generation unit 124, the earthquake detection signal transmission unit 125, and the property identification data setting unit 126 Have.

[0022] The P wave level setting unit 121 is set with a predetermined level for detecting a P wave (for example, a predetermined signal level expected to be generated between M3 and less than M5). . The control operation instruction signal generation unit 122 compares the signal level sent from the P-wave earthquake sensor 15 with the setting level of the P-wave level setting unit 121, and when the sensor signal level exceeds the setting level. , P wave detection is detected, and a signal for starting the control operation mode is sent to the operation control unit 11.

[0023] Here, the control operation mode means that after each elevator is operated to the nearest floor, the doors are opened and the passengers are lowered, the doors are closed and the doors are closed for a predetermined time (for example, until S wave detection). This is an operation mode.

[0024] The S wave level setting unit 123 is set with a predetermined level for detecting the S wave (for example, a predetermined signal level between the mag-mode M3 and less than M5). The elevator stop instruction signal generator 124 compares the signal level sent from the S-wave seismic sensor 16 with the set level of the S-wave level setting unit 123, and when the sensor signal level exceeds the set level, The s-wave detection is determined and an elevator stop instruction signal is sent to the operation control unit 11 and an S-wave detection signal is sent to the earthquake detection signal transmission unit 125.

When the earthquake detection signal transmission unit 125 receives the S wave detection signal, the earthquake detection signal transmission unit 125 attaches the property identification data set in the property identification data setting unit 126 to the S wave detection signal and transmits the property identification data to the monitoring device 2.

FIG. 3 is a diagram illustrating a configuration example of the monitoring device 2.

[0027] The monitoring device 2 has a program memory 21 for storing program data defining the processing procedure.

A monitoring control processing unit 22, an input unit 23, a nother memory 24, a display unit 25, and a center database 26.

[0028] Upon receiving the S-wave detection signal with the property identification data from each earthquake detection control unit 12, the monitoring control processing unit 22 stores and displays the property current information in the monitored property information table 26a shown in FIG. To do.

[0029] The monitored property information table 26a is represented in a tabular format. For each monitored region (for example, Tokyo, Kanagawa, Chiba, Saitama, etc.), the target property identification data, property name (building) Item name), property address, property current information, marking data, etc., and record the current property information issued from each monitored property 1,….

[0030] The input unit 23 inputs various data and control commands.

[0031] In addition to the property identification data and S wave detection signal transmitted from each monitored property 1, ..., the nota memory 24, for example, an inspection signal, emergency power sent along with the property identification data, Various data such as call signals are temporarily stored.

[0032] The display unit 25 displays information obtained by excluding, for example, marking data from the property information stored in the monitored property information table 26a shown in FIG.

[0033] The monitoring control processing unit 22 includes a CPU. Functionally, as shown in FIG. 5, the property information receiving / writing unit 221, the marking processing unit 222, and the property information display unit 223 are provided.

[0034] Upon receiving the S-wave detection signal with the property identification data from each earthquake detection control unit 12, the property information receiving / writing unit 221 receives the monitored property name from the monitored property information table 26a stored in the center database 26. The property corresponding to the property name Write elevator stop data in the information area.

[0035] When the monitoring target property information shown in FIG. 4 is displayed, the marking processing unit 222 performs processing for marking each type of property current information. Here, the types of property current information include, for example, elevator stop, emergency call due to force closing, inspection work, fire, etc. The property information display unit 223 displays the monitored property information excluding marking data on the display unit 25.

[0036] Next, the operation of the remote monitoring system configured as described above will be described with reference to FIGS.

FIG. 6 is a flowchart for explaining an operation procedure of the earthquake detection control unit 12 of the elevator control device 4 in each monitored object 1,.

[0038] The earthquake detection control unit 12 constantly takes in the outputs of the P-wave earthquake sensor 15 and the S-wave earthquake sensor 16 and monitors the occurrence of an earthquake.

[0039] That is, the earthquake detection control unit 12 takes in the P wave signal sent from the P wave earthquake sensor 15 (step S1), and compares this signal level with the setting level of the P wave level setting unit 121. Then, it is determined whether or not the force detected the P wave due to the occurrence of the earthquake (step S2). If the received signal level has not reached the set level, the process returns to step S1 and the same process is repeated.

[0040] When the received signal level exceeds the set level, the earthquake detection control unit 12 determines that a P wave has been detected, and outputs a signal for starting the control operation mode to the operation control unit 11. Send out (step S3). The processes in steps S1 to S3 correspond to the control operation start signal generator 122 shown in FIG.

When the operation control unit 11 receives the control operation mode start signal from the earthquake detection control unit 12, the operation control unit 11 switches to the control operation mode and performs operation control. As described above, the control operation mode is a mode in which, after driving the car to the nearest floor, the door is opened, the passenger is lowered, the door is closed, and the vehicle is paused. Therefore, the operation control unit 11 reads out the message data from the message data setting unit 14 while operating each elevator toward the nearest floor, and issues it to the car.

Specifically, as shown in FIG. 7 (a), for example, “There is a possibility of an earthquake. Read the message “I will pause” and output the sound from the sound generator installed in the car of each elevator or display it on the display installed in the car. In this way, issuing a message in the car has the effect of prompting passengers in the car to get off.

[0043] On the other hand, after detecting the P wave, the earthquake detection control unit 12 takes in the signal sent from the S wave earthquake sensor 16 (step S4), and sets the signal level and the set level of the S wave level setting unit 123. Are compared to determine whether the force detected the S wave due to the occurrence of an earthquake (step S5).

Here, if the received signal level does not reach the set level, the process returns to step S1, and the same process is repeated. On the other hand, if the received signal level exceeds the set level, it is determined that an S wave has been detected, and an operation stop instruction signal is sent to the operation control unit 11 (step S6). The processes in steps S4 to S6 correspond to the elevator stop instruction signal generator 124 shown in FIG.

Further, when detecting the S wave, the earthquake detection control unit 12 takes out the property identification data “for example, 10001” from the property identification data setting unit 126, adds it to the S wave detection signal, and transmits it to the monitoring device 2 ( Step S 7).

That is, the earthquake detection control unit 12 does not transmit the P wave detection effect to the monitoring device 2 when the P wave is detected, and does not transmit the S wave detection to the monitoring device 2 when it is determined that the S wave is detected. Send wave detection signal. As a result, the number of times the communication line 3 is used can be almost halved, and at the monitoring device 2 side, it can be recognized that at least the elevator is stopped. The processing in step S7 corresponds to the earthquake detection signal transmission unit 125 shown in FIG.

When the operation control unit 11 receives an elevator stop signal from the earthquake detection control unit 12, the operation control unit 11 stops the operation of each elevator and reads out message data from the message data setting unit 14, Report to each floor platform.

[0048] Specifically, as shown in Fig. 7 (b), "An earthquake occurred. The elevator will be stopped!" Read the message and say “I am stopped on the 0th floor due to the occurrence of an earthquake”! Display on the hall indicator. In this way, the elevator users who are waiting at each floor hall are informed of the operating state of the elevator, thereby promoting the calm behavior. There are fruits.

At this time, the monitoring device 2 in the monitoring center executes the following processing.

That is, the monitoring processing control unit 22 of the monitoring device 2 takes in the S-wave detection signal with the property identification data transmitted from each monitored property 1,..., Stores it in the buffer memory 24 sequentially, and performs predetermined processing. Execute.

FIG. 8 is a flowchart for explaining the operation procedure of the monitoring process control unit 22 of the monitoring device 2.

[0051] After performing initialization processing according to the program data in the program memory 21 (Step S11), the monitoring processing control unit 22 performs property information from each monitored property 1, ... (S wave detection signal with property identification data) ) Is received or not (step S12). If it is received! /, N! /, It will be in reception standby status.

[0052] On the other hand, when the property information is received, the monitoring processing control unit 22 uses the property identification data (for example, 10001) of the property information to display the property to be monitored in the property information table 26a to be monitored shown in FIG. Referring to the identification data, specify the property name “XXA Building”. Then, “Property current information type 01” is written in the property current information area corresponding to the subject name while the elevator is stopped based on the S wave detection signal (step S13). The processes in steps S12 and S13 correspond to the property information reception / writing unit 221 shown in FIG.

[0053] Subsequently, the monitoring process control unit 22 determines whether or not to perform the marking process after writing the property current information (step S14). If it is determined that the marking process is to be performed, the marking process is performed on the property information to be monitored corresponding to the corresponding property name based on the marking data in the marking data area (step S15).

The marking process is a process for making it possible to recognize at a glance what state each of the monitored objects 1,. For example, it makes it possible to recognize whether the elevator is currently stopped or the emergency call is due to the car being trapped. On the other hand, when no marking is given, it is possible to grasp that the vehicle is in a normal operating state without corresponding to the cause to be set in advance. The processes in steps S14 and S15 correspond to the marking processing unit 222 shown in FIG.

[0055] After performing the marking process, the monitoring process control unit 22 performs monitoring target property information shown in FIG. Of the property information in Table 26a, the monitored property information excluding the marking data is sequentially read and displayed on the display unit 25 (step S16). The processing in step S16 corresponds to the property information display unit 223 shown in FIG. Then, after displaying the property to be monitored, the monitoring processing control unit 22 determines whether or not it is a power to continuously display (Step S17). If the display is to be continued, return to step S12 and repeat the same process.

[0056] As described above, this embodiment has the following effects.

Force that P and S waves are generated when an earthquake occurs Previously, both the P wave detection signal and the S wave detection signal detected by each of the seismic sensors 15 and 16 were transmitted to the monitoring device 2. However, if the above detection signals are sent to the communication line 3 all at once from the monitored objects 1,... Scattered over a wide area, the communication line 3 connected to the monitoring device 2 is in a punctured state.

On the other hand, in the remote monitoring system according to the present embodiment, when the P wave is detected, only the activation signal for the control operation mode is sent to the operation control unit 11 and is not transmitted to the monitoring device 2. After that, when the S wave is detected, the S wave detection signal is transmitted to the monitoring device 2. As a result, the number of uses for the communication line 3 is almost halved, and the use of the communication line 3 corresponding to the decrease can be distributed to the property information from other monitored properties 1, ... other than the occurrence of the earthquake. As a result, even when an earthquake occurs, it is possible to reliably receive various property information related to the monitored properties 1, ... scattered in areas outside the earthquake occurrence area. This means that very important property information other than earthquakes can be reliably monitored, and maintenance personnel are dispatched to the site quickly.

[0058] In addition, in this remote monitoring system, the monitoring device 2 performs marking for each monitored object 1,... Based on the type of the current property information. As a result, it is possible to recognize at a glance what the status of each monitored object 1, ... is currently, and bring each maintenance object, etc. according to the status of each monitored property 1, ... Maintenance personnel can be dispatched. That is, it becomes possible to proceed with maintenance work quickly.

[0059] (Second Embodiment)

Next, a second embodiment of the present invention will be described.

In the second embodiment, when monitoring monitored objects 1,... Over a wide area, or a large number of monitored objects in each monitored area (for example, Tokyo, Kanagawa Prefecture, etc.). It is to realize an effective configuration for a remote monitoring system having 1,.

[0060] This will be described with reference to FIG.

Multiple monitoring devices 2, ... are installed in the monitoring center. Since each monitoring device 2 has a large number of monitored objects 1,... In each monitored area, monitoring is performed in a distributed manner in each monitored area. That is, one monitoring device 2 monitors the Tokyo area, and another monitoring device 2 monitors the Kanagawa 11 prefecture area.

Here, in the second embodiment, the monitoring devices 2... Are distributed in the internal network (LAN etc.) 31. A large display board 33 is connected to the internal network 31 via a display computer 32. The display computer 32 displays the monitored property information transferred from each of the monitoring devices 2,... On the large display board 33 in accordance with the monitored region.

[0062] Therefore, each monitoring device 2 is provided with an individual display unit 25. However, the entire monitoring device 2,... It is possible to do.

FIG. 9 is a functional block diagram showing the internal configuration of each monitoring device 2 in the remote monitoring system.

[0064] Each monitoring device 2 includes a property information reception / writing unit 221, a marking processing unit 222, a property information display unit 223, and a specific property extraction / display unit 224 and a specific property all-cases transfer unit 225. . The property information receiving / writing unit 221, the marking processing unit 222, and the property information display unit 223 are the same as those in FIG.

The specific property extraction display unit 224 extracts specific property current information (for example, “01” when the elevator is stopped) from the property information in the monitored property information table 26a shown in FIG. The transfer section 225 for the transfer of all specified properties transfers all the monitored property information extracted to the internal network 31 and displays it on the large display board 33 via the display computer 32.

Next, the operation of the monitoring device 2 having such a configuration will be described.

FIG. 10 is a flowchart for explaining the operation of the monitoring device 2 according to another embodiment of the present invention. Steps S11 to S16 in the figure have already been described with reference to FIG. [0067] After displaying the monitored property information on the display unit 25, the monitoring processing control unit 22 of the monitoring device 2 determines whether or not the present property information has the power to display the current property information of the type where the elevator is stopped. (Step S21). For example, when there is an earthquake, there is a request to display only the monitored property that is affected by the earthquake, and there are cases where it is desirable to display an emergency call for confining the car in cases other than an earthquake.

Therefore, the monitoring person inputs data “01” indicating the elevator stop and the property extraction instruction from the input unit 23. When receiving the property extraction instruction having the data “01”, the monitoring process control unit 22 determines to display the current property information of the type where the elevator is stopped. Then, only the property information when the elevator is stopped is extracted (step S22) and displayed on the display unit 25 (step S23).

[0069] As described above, the extraction of the specific property current information type is not limited to when the elevator is stopped. The processes in steps S21 to S23 correspond to the specific property extraction display unit 224 shown in FIG.

[0070] Subsequently, the monitoring processing control unit 22 determines whether or not the power is to be transferred to the display computer 32 (step S24). Here, if there is a preset flag or a transfer instruction input from the input unit 23, it is determined that the extracted property information is to be transferred, and all the monitored property information shown in FIG. 4 relating to when the elevator is stopped is transferred to the display computer 32. Yes (Steps S 25, S 26) ₀ The processes in steps S 24 to S 26 correspond to the specific property all-case transfer unit 225 shown in FIG.

When the display computer 32 receives specific monitored object information from each of the monitoring devices 2,..., The display computer 32 arranges the information for each property information type and each monitored area and displays the information on the large display board 33. At this time, it can be displayed cyclically alternately for each property information type.

[0072] As described above, according to the present embodiment, only the monitoring object condition information of the property type required by the observer is extracted and displayed on the display unit 25. Immediately understand the condition. In addition, it is possible to easily grasp in which area the elevator stops frequently due to the occurrence of an earthquake, and to take measures including the number of personnel when dispatching maintenance personnel. [0073] Also, by extracting only the monitored property information of the property type required by the observer and displaying it on the large display board 33, the observer who monitors a specific area can be affected by earthquakes in other areas. Elevator status can be easily grasped.

[0074] (Other Embodiments)

(1) In the above embodiments, the seismic sensors 15 and 16 for P wave and S wave are divided. However, one seismic sensor may be shared. In addition, although the P wave level setting unit 121 and the S wave level setting unit 123 are provided separately, the level for the P wave and the S wave may be set in one level setting unit.

(2) The property information in the monitored property information table 26a shown in FIG. 4 is an example of an information array for display on the display unit 25 in a table format. For example, if you want to display a property to be monitored on the map display screen of the region to be monitored, this can be realized by adding latitude and longitude information for each property name.

[0076] (3) In each of the above embodiments, the present invention can be applied to other elevator equipment such as a force estimator described by taking remote monitoring of an elevator as an example, and any other property or equipment that can be remotely monitored.

[0077] In addition, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.
