Description

  The present invention relates to a remote monitoring system for remotely monitoring the state of an apparatus in a batcher plant, which is an apparatus for producing ready-mixed concrete.

  Conventionally, in a batcher plant, ready-mixed concrete is manufactured based on gravel (coarse aggregate), sand (fine aggregate), cement, water, admixture and the like, which are constituent materials of ready-mixed concrete. In the batcher plant, coarse aggregate, cement, and the like are transported from the storage silo that stores them to the batcher plant main body by a belt conveyor, pneumatic transportation equipment, or the like. The conveyed coarse aggregate or the like is kneaded with water, an admixture, or the like in the batcher plant body, thereby producing ready-mixed concrete. The produced ready-mixed concrete is put into an agitator vehicle (mixer vehicle) that moves to the lower part of the batcher plant body, and is transported to each construction site by the agitator vehicle.

  Inside the tower-shaped batcher plant body, there are various storage bins for storing materials, weighing bins for weighing materials, mixers for kneading materials, hoppers for putting ready-mixed concrete into agitator cars, etc. Equipment is provided. Each device of the batcher plant is controlled by an operation panel installed in the operation room. In other words, when manufacturing raw concrete, when the composition of materials is set and input to the operation panel by a field worker, a signal for opening and closing the open / close gate provided in the weighing bin or driving the mixer is displayed. Is sent to each device, and the production process of ready-mixed concrete is managed by this.

  The operation room in which the operation panel is installed is laid not on the inside of the batcher plant main body, but on the outer surface of the batcher plant main body or other places in the plant site. Field workers are usually facing the control panel during the production of ready-mixed concrete and are not in the batcher plant body, so it is necessary to ascertain whether or not each device in the batcher plant is operating normally. I can't.

  For example, if any device fails, the production process of ready-mixed concrete will be disturbed, but the operation panel will only indicate that the manufacturing process has been disrupted, not which device has failed. There are many cases. For this reason, the field worker cannot reliably grasp which device has failed.

  Therefore, on-site workers, for example, go into the batcher plant body to investigate the cause of the trouble in the manufacturing process, but because they do not know which device is in failure state, It took a long time to identify and investigate the cause of failure. In addition, when the equipment is about to break down, the production of ready-mixed concrete can be performed apparently, so the field worker could not grasp it.

  FIG. 1 is a schematic configuration diagram showing a remote monitoring system according to the present invention. The remote monitoring system is applied to a batcher plant that manufactures ready-mixed concrete, and is for remotely monitoring each device of the batcher plant. The batcher plant 1 includes a tower-like plant main body 2 for producing ready-mixed concrete, and an operation panel 3 for controlling each device in the plant main body 2. The operation panel 3 is provided, for example, in an operation room 4 laid in a place away from the plant main body 2. The operation room 4 may be laid on the outer surface of the plant body 2.

  The field worker usually manages the manufacturing process of ready-mixed concrete against the operation panel 3 at the time of manufacturing ready-mixed concrete. Since the field worker is in the operation room 4, it cannot immediately grasp that various devices in the plant main body 2 have failed or are in a state before the failure. The remote monitoring system is for remotely monitoring various devices in the batcher plant 1 and reliably and immediately informing field workers of the failure status of various devices.

  The remote monitoring system according to this embodiment includes “a device provided in the batcher plant 1 (hereinafter referred to as“ plant-side device ”)”, “Internet line”, and “a device provided in a facility on the manufacturer side (hereinafter referred to as“ manufacturer ”). "Side device")) ". The manufacturer side device functions as the remote control device described in the claims.

  Here, the batcher plant 1 stores the conveyor 5, fine aggregate, and coarse aggregate that are supplied to the plant body 2 from an aggregate silo (not shown) for storing each material such as fine aggregate and coarse aggregate. Turn chute 6 for distributing to bin 7 (described later), storage bin 7 for storing each material, weighing bin 8 for weighing each material, mixer 9 for kneading these materials, agitator wheel (not shown) Various devices such as a hopper 10 for putting ready-mixed concrete into are provided.

In addition, the storage bin 7 and the weighing bin 8 are respectively provided with open / close gates 13 and 14 called cut gates below them. Actuators 15 and 16 are respectively arranged on the open / close gates 13 and 14, and the open / close operations of the open / close gates 13 and 14 are performed by the actuators 15 and 16.

  In the present embodiment, whether or not each device is operating normally is monitored based on the sound during operation of the motors 11 and 12 and the actuators 15 and 16. Hereinafter, the motors 11 and 12 and the actuators 15 and 16 are collectively referred to as “monitored devices”.

  The operation panel 3 includes, for example, a display unit composed of a large CRT, an operation unit having various switches and a keyboard, and a control unit serving as a control center for each of the above devices (all not shown). A control part sends out an operation start signal to each apparatus and plant side control device 19 (after-mentioned). In particular, the plant-side control device 19 also sends information indicating to which device the operation start signal has been sent (hereinafter referred to as “device identification information”).

  The plant side device of this remote monitoring system is configured by a microphone 18 for inputting sound generated from each monitoring target device and a plant side control device 19 installed in the operation room 4.

  A plurality of microphones 18 are provided and are arranged in the vicinity of the monitoring target device. That is, the microphones 18 are arranged in the vicinity of the motors 11 and 12 of the conveyor 5, the turn chute 6 and the mixer 9, the storage bins 7 and the actuators 15 and 16 of the weighing bins 8 and the like, and are generated from the monitored devices. Input the audio of the hour. Note that the connection between the microphone 18 and the plant-side control device 19 may be wired or wireless.

  The plant-side control device 19 inputs the voice from the microphone 18 and sends it as data to the Internet line N, or notifies the failure determination result of each monitored device sent from the manufacturer-side device (details will be described later). It is something to do.

  As shown in FIG. 2, the plant-side control device 19 includes a control unit 20. The control unit 20 serves as a control center of the plant-side control device 19. The control unit 20 includes a plurality of A / D conversion units 21, an I / F unit 22, a communication unit 23, a storage unit 25, and a display unit. 26 is connected.

  The A / D converter 21 converts an analog signal, which is a sound input to the microphone 18, into a digital signal. The I / F unit 22 manages the interface of the operation panel 3. The communication unit 23 performs data communication with the manufacturer side device via the Internet line N. The storage unit 25 temporarily stores data handled by the control unit 20. The display unit 26 displays, for example, the failure determination result of each monitoring target device transmitted from the manufacturer side device in response to a command from the control unit 20.

  The communication unit 23 is connected to the modem 27 with the Internet line N. The connection between the Internet line N and the modem 27 and the connection between the modem 27 and the communication unit 23 may be performed by wire or wirelessly.

  Note that individual plant identification information is set in the batcher plant 1 in advance. The plant identification information can be identified by the manufacturer's equipment, and indicates the preset plant number, plant size and type, model of each device, production specifications of ready-mixed concrete, etc. is there.

  The plant-side control device 19 records the voice input by the microphone 18 in the form of data (hereinafter, the voice data recorded by the plant-side control device 19 is referred to as “recorded voice data”) and sends it to the manufacturer-side device. Here, the plant identification information and the device identification information are added to the recorded audio data.

  The Internet line N is a network using a so-called Internet protocol, and is used for communication of voice data, various control signals and the like between the plant side device and the manufacturer side device in this embodiment.

  The maker-side device of the remote monitoring system is installed in a maker's call center (for example, department equipment for maintenance work), and includes, for example, a control device 30 (hereinafter referred to as “maker-side control device 30”) composed of a personal computer and a database 31. Composed.

  The manufacturer-side control device 30 collates the recorded voice data sent from the plant-side control device 19 with the regular voice data stored in the database 31, and uses the collation result as a failure determination result to the plant-side control device 19. Send back. Here, the regular audio data is originally stored as data that is emitted to the outside during normal operation of each monitored device. For example, as indicated by the solid line S in FIG. It is represented by a waveform showing the relationship with the size (dB).

  As shown in FIG. 4, the regular audio data is stored for each of a plurality of batcher plants and for each of a plurality of monitored devices. More specifically, the regular audio data is a predetermined sampling period (for example, 0.2 seconds) from the start of the operation of the monitoring target device (the motor 12 of the mixer 9 in FIG. 4) to a predetermined elapsed time. Every one is remembered. As shown in FIG. 4, when the elapsed time is 10 seconds, there are 50 regular audio data (M1 to M50). The waveform shown in FIG. 3 shows one example indicated by any data number.

  For example, when the monitoring target device is the mixer 9, the rotational speed becomes substantially constant within a few seconds after the motor 12 starts rotating. Therefore, if there is not much change in the audio data after the rotation speed of the motor 12 becomes substantially constant, the sampling cycle is set slightly longer after the time until the rotation speed becomes substantially constant. You may do it. Alternatively, after the time until the rotational speed of the motor 12 becomes substantially constant has elapsed, recording of audio data may be terminated.

  In addition, as shown in dotted lines Tu and Td in FIG. 3, the regular audio data includes a predetermined allowable width W (for example, ± 5 dB) in the sound volume at each frequency. The recorded voice data from the plant-side control device 19 is collated with the regular voice data, and when the volume of the recorded voice data is within the allowable width W, it is determined that the monitoring target device has not failed. Is done. On the other hand, when the volume of the recorded audio data deviates from the allowable width W, it is determined that the monitoring target device has failed.

  The manufacturer-side control device 30 includes a control unit 32 as shown in FIG. The control unit 32 is a control center of the manufacturer-side control device 30, and is connected to a communication unit 33, a storage unit 34, a display unit 35, an input unit 36, and an I / F unit 37.

  The communication unit 33 performs data communication with the plant side device via the Internet line N. The storage unit 34 temporarily stores data handled by the control unit 32. The display unit 35 displays a failure determination result of each monitoring target device of audio data. The input unit 36 is composed of, for example, a keyboard, and is used for operation input by a manufacturer staff. The I / F unit 37 governs the interface of the database 31.

  The communication unit 33 is connected to the modem 38 with the Internet line N. The connection between the Internet line N and the modem 38 and the connection between the modem 38 and the communication unit 33 may be performed by wire or wirelessly.

  As shown in FIG. 4, the database 31 stores the above-described regular audio data of the monitoring target device in the batcher plant at every sampling timing. As described above, the database 31 stores plant identification information for each of a plurality of batcher plants, and regular sound data is stored in association with the plant identification information.

  As described above, plant identification information and device identification information are added to the recorded voice data sent from the plant-side control device 19. For this reason, the manufacturer-side control device 30 can specify any batcher plant from among a large number of batcher plants by using the plant identification information and the device identification information, and can generate a normal voice in a desired monitoring target device of the specified batcher plant. Data can be read out.

  Further, the regular audio data stored in the database 31 may be updated as necessary. For example, when a monitored device is replaced, the generated sound may differ from the monitored device before replacement. In such a case, the sound data of the monitored device after replacement is monitored before replacement. It may be overwritten with the regular audio data of the target device and stored in the database 31. In this case, the plant-side control device 19 adds an update instruction signal for updating to the new voice data and sends it to the maker-side control device 30, and the maker-side control device 30 based on the update instruction signal. Update may be performed. Alternatively, for example, a manufacturer staff member may perform an operation for storing the transmitted new voice data in the database 31.

  Next, an example of a remote monitoring method using this remote monitoring system will be described.

  When the site worker inputs data such as the composition of ready-mixed concrete to be manufactured sent from the shipping management device (not shown) using the operation panel 3, the manufacture of ready-mixed concrete is started in the batcher plant 1. The operation panel 3 sequentially sends an operation start signal to each device according to the production process of ready-mixed concrete.

  For example, when supplying material from the conveyor 5 to the plant main body 2, the operation panel 3 sends an operation start signal for driving the conveyor 5 to a motor (not shown) of the conveyor 5. The operation panel 3 sends an operation start signal for opening the open / close gate 13 to the actuator 15 of the storage bin 7 when the material is charged from the storage bin 7 to the measuring bin 8. Alternatively, the operation panel 3 sends an operation start signal for rotationally driving the motor 12 of the mixer 9 when the mixer 9 starts kneading the input material.

  As described above, when the operation panel 3 sends an operation start signal to the monitoring target device among the devices, the operation panel 3 also sends an operation start signal to the plant-side control device 19. The operation start signal includes device identification information. Is granted.

  The control unit 20 of the plant side control device 19 determines whether or not an operation start signal is sent from the operation panel 3 (S1). When receiving the operation start signal and the device identification information from the operation panel 3 (S1: YES), the control unit 20 recognizes the monitoring target device based on the device identification information (S2). Thereafter, the control unit 20 inputs the voice in the monitored device and records it as voice data (S3).

  Specifically, the sound in the monitored device is input through the microphone 18 and is analog-digital converted by the A / D conversion unit 21. The plant-side control device 19 temporarily stores the analog-digital converted voice signal in the storage unit 15 as digital data.

  The control unit 20 inputs audio at a predetermined sampling period (for example, 0.2 seconds) until a predetermined time elapses after the operation start signal of the monitoring target device is input, and stores audio data at each sampling timing 15 is stored. For example, if the monitoring target device is the mixer 9, as shown in FIG. 4, 50 pieces of waveform data (M1 to M50) are stored.

  When the recording of the recorded audio data is completed, the control unit 20 reads the recorded audio data from the storage unit 15 and sends them to the Internet line N with the manufacturer side control device 30 of the manufacturer side device as the transmission destination (S4). . At this time, plant identification information and device identification information are added to the recorded audio data.

  Note that the recorded audio data may be sent sequentially to the Internet line N immediately when audio is input from the microphone 18. Further, when the recording of the recording audio data is finished, a recording completion signal may be sent from the plant side control device 19 to the manufacturer side control device 30.

  The control unit 32 of the manufacturer-side control device 30 determines whether or not to receive recorded voice data from the plant-side control device 19 (S5). When receiving the recording voice data from the plant side control device 19 via the Internet line N (S5: YES), the control unit 32 analyzes the plant identification information and the device identification information given to the recording voice data, and records the voice data. Is recognized from which batcher plant 1 and which monitored device it is (S6). Then, the received recorded voice data is temporarily stored in the storage unit 15 together with the plant identification number and the device identification information.

  Next, the control unit 32 collates the recorded voice data with the regular voice data stored in the database 31. Specifically, the control unit 32 reads out regular voice data corresponding to the batcher plant and the monitoring target device recognized in step S6 from the database 31 (S7). Then, the control unit 32 collates the recorded voice data with the regular voice data (S8), and temporarily records the collation result (failure determination result) in the storage unit 25.

  For example, as shown in FIG. 7, when the sound volume of the recorded audio data (see symbol R) deviates from the allowable width W at a certain frequency (see, for example, symbol E), it is determined that the monitoring target device is faulty. That is, in the waveform shown in FIG. 7, it is assumed that an abnormal sound is generated at a certain frequency.

  In addition, from the waveform shown in FIG. 7, you may make it identify not only the presence or absence of a failure but the condition of a failure. For example, as shown in FIG. 8, when there are two waveforms in which the volume of the recorded audio data (see symbol R) deviates from the permissible width W in the high frequency range, for example, oil shortage or oil leakage of the monitoring target device You may make it discriminate | determine. As a failure situation, in addition to the above-mentioned oil shortage or oil leakage, air leakage, grease shortage, electrical chattering, electrical surge, or the like may be specified.

  When the control unit 32 collates the recorded voice data with the regular voice data, the display unit 35 displays the failure determination result of each monitored device. In this case, for example, the manufacturer staff member may instruct the field worker on the plant side to replace the device according to the failure determination result displayed on the display unit 35. Alternatively, the manufacturer staff may go directly to the site and perform work such as equipment replacement.

  Further, as described above, the following may be adopted as a condition for updating the regular audio data stored in the database 51. That is, for example, when the waveform shown in FIG. 7 is not determined to be a failure and voice data having the same waveform is sent several times in succession, the waveform is stored in the database 51 as regular voice data to be updated. You may make it do.

  The control unit 32 sends the collation result to the plant-side control device 19 via the Internet line N (S9). In this case, the transmitted data includes plant identification information of the corresponding batcher plant, device identification information of the corresponding monitoring target device, and the like in addition to the above collation result.

  The control unit 32 sends the collation result or the like toward the plant-side control device 19, and then returns to step S5 to determine whether or not the next recorded voice data has been received from the plant-side control device 19.

  In the control unit 20 of the plant side control device 19, it is determined whether or not verification result data has been received from the manufacturer side control device 30 via the Internet line N (S10). Specifically, the control unit 20 determines whether or not the verification result data is received by determining whether or not the received verification result data includes the corresponding plant identification information. .

  When determining that the collation result from the manufacturer-side control device 30 has been received (S10: YES), the control unit 20 temporarily stores the collation result as data in the storage unit 15 and displays it on the display unit 16 (S11). . For example, when the monitoring target device is the mixer 9 and it is determined that it is out of order, the display unit 26 displays “Mixer is out of order”. If it is determined in the failure determination result that the monitored device has not failed, a message such as “No failure device” is displayed.

  As described above, according to the remote monitoring system of the present embodiment, when the production of ready-mixed concrete is started, the sound produced by each monitored device of the batcher plant 1 is sent as data to the manufacturer side device. Then, the manufacturer side device collates with the regular voice data, and the collation result is transmitted to the plant side control device 19 in the operation room 3 and displayed.

  The field worker can grasp the monitoring target device that has failed by viewing the determination result displayed on the display unit 26 of the plant-side control device 19. And a field worker can go to the field of batcher plant 1, and can check the state of the monitoring object apparatus which has failed.

  Usually, the field worker is in the vicinity of the operation panel 3 in the operation room 4 when the ready-mixed concrete is generated. Therefore, the plant-side control device 19 disposed in the vicinity of the operation panel 3 is used to monitor the equipment of the batcher plant 1. Can be recognized without going to the inside of the plant main body 2, for example.

  Therefore, as in the conventional configuration, it was impossible for field workers to immediately recognize which device had failed, or to spend a long time identifying the failed device and investigating the cause of the failure. Can be solved.

  In the present embodiment, as shown in FIG. 3, the sound volume of the regular audio data has an allowable width W, and when the sound volume of the recorded audio data deviates from the allowable width W, Although it has been determined that the monitoring target device has failed, for example, a state in which the monitoring target device is about to fail may be recognized based on an allowable width W ′ smaller than the allowable width W.

  Specifically, when a permissible width W ′ smaller than the permissible width W is set for each frequency, and the volume of the recorded audio data deviates from the permissible width W ′ and does not deviate from the permissible width W, the monitoring target It may be recognized that the device is about to fail. That is, when the monitored device is in a state of being out of order, an abnormal sound is likely to be produced, and in the above, it is assumed that the monitored device is in a state of being out of order due to the abnormal sound that is easily produced. .

  Further, in the remote monitoring system according to the present embodiment, when the failure of the monitoring target device cannot be determined based on the voice, that is, although the verification result based on the voice is recognized as normal, If there is a problem in the process, the failure of the monitored device may be determined based on the image.

  In other words, the plant side device is provided with a camera for imaging the device to be monitored, the image captured by the camera is sent as data to the manufacturer side device, and the manufacturer side device collates with the regular image data to be monitored. You may make it discriminate | determine whether the apparatus is out of order.

  Instead of the camera, for example, a field worker may take an image of the monitoring target device using a tablet terminal, and send the captured image data to the manufacturer-side control device 30 via the plant-side control device 19. . In this case, on the maker side, for example, the maker staff actually looks at the image data sent from the plant-side control device 19 to determine whether or not the equipment is out of order. It may be instructed to replace it. Alternatively, the manufacturer staff may go directly to the site and perform work such as equipment replacement.

  Further, for example, when an image is captured by a tablet terminal or the like, the image data may be sent directly to the manufacturer-side control device 30 via the Internet line N without going through the plant-side control device 19. In this case, in the tablet terminal or the like, the batcher plant and the monitoring target device can be specified by the manufacturer-side control device 30 by adding the identification information of the batcher plant and the monitoring target device to the image data.

  Instead of a tablet terminal, a smartphone, a mobile phone, a video camera, a digital still camera, a wearable device (including a camera), or the like may be used. The image may be a moving image or a still image.

  The scope of 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. For example, the configuration of the batcher plant 1, the monitoring target device, the plant side device, the manufacturer side device, and the like is not limited to the above-described embodiment. In the above embodiment, the failure of the device is determined based on the volume of the sound. Alternatively, the failure of the device may be determined based on the sound generation cycle, the continuous time during which the abnormal sound is generated, or the like. Good. Alternatively, the temperature of the motor 12 may be measured, and the failure of the device may be determined based on the measured temperature and the loudness.

  Moreover, in the said embodiment, although the operation panel 3 for controlling each apparatus in the plant main body 2 and the plant side control apparatus 19 were made into the apparatus which became independent separately, the plant side control apparatus 19 is an operation. It may be included in the board 3. However, if the plant-side control device 19 is separate from the operation panel 3 in terms of hardware, the operation panel 3 is less affected by adverse effects (for example, viruses) from the Internet line N, for example. The control device 19 is preferably independent of the operation panel 3.

  Moreover, in the said embodiment, although the database 31 may be contained in the plant side apparatus instead of the manufacturer side apparatus, there exists a fault that the apparatus cost by the database 31 increases in a manufacturer side apparatus. Further, if the database 31 is included in the manufacturer side device, the manufacturer side can collect and manage the voice data of the monitoring target devices in all the batcher plants, so that the monitoring target device records in other batcher plants can be recorded. When comparing with audio data, the system is suitable.
