Description

  The present invention relates to a boiler room monitoring device that monitors operating states of a plurality of devices including a boiler disposed in a boiler room.

  First, the background that led to the present invention will be described. Over the past 30 years, the demand for steam boilers (hereinafter simply referred to as “boilers”) has shifted from large boilers that need to be handled by boiler engineers to small once-through boilers that do not require boiler engineers. In reality, the number of small once-through boilers installed has increased significantly. Actually, as a boiler installed every year, a small-sized once-through boiler is about 95% in the number of production and about 90% in the amount of evaporation. Although this small once-through boiler does not require a boiler engineer, if the boiler stops due to some abnormality, it may cause a situation that the operation of the factory or the like is stopped, resulting in a large amount of damage.

  Therefore, the boiler user entrusts maintenance management of the boiler with a maintenance management contract (hereinafter referred to as “maintenance manager”). Here, when a maintenance management contract is concluded, the user is referred to as a contractor (also referred to as a user). When the maintenance management contract is not concluded, the user is referred to as a user (user). In the following description, it is assumed that the maintenance management is concluded.

  The maintenance manager has constructed a maintenance management system for preventing early abnormality recovery and occurrence of abnormality using communication technology. This maintenance management system is equipped with various sensors for monitoring the operating state of the boiler, and determines whether or not there is an abnormality based on the detection signal from the sensor. Information is transmitted to the base computer of the maintenance manager. The management base that has received the alarm information dispatches a service person (maintenance person) to the site where the abnormality has occurred, so as to recover the abnormality at an early stage. On the other hand, when an abnormality or the like occurs, the content of the alarm is displayed on the boiler display so that the service staff can confirm it on site and the user can know. (For example, see Patent Document 1)

  The number of alarms displayed on the boiler display is as high as 50 or more in some models. Also, along with the popularization of the boiler, the popularization of ancillary equipment such as water softeners and deoxygenators attached to the boiler is also remarkable, and these ancillary equipments are also digitized and networked in the same way as the boilers. Various alarms are displayed every time.

  Such conventional techniques have the following problems. First, as described above, the components of the boiler room may be located anywhere in the boiler chamber even if an abnormality occurs in the equipment due to a significant increase in the number of the boilers, the types and the number of the auxiliary equipment. It is becoming difficult to grasp whether this has occurred. That is, there is a problem that it is difficult for the contractor to grasp the operation state of the entire boiler room. In addition, the boiler and the ancillary equipment may have different alarm styles, making it difficult for the contractor to understand.

  Now, it is assumed that the abnormality information of the gas pressure abnormality is generated in the third machine of the first to eighth machine groups of the first system group of the boiler group. Then, an alarm occurrence display process of S3 is performed. That is, the process proceeds to S8 in FIG. 14, and the monitoring panel first display 19 displays the alarm screen 36 shown in FIG. In FIG. 9, the first communication display symbol 60 of the main display unit 37 and the fixed display unit 39 is displayed in red indicating that it is the abnormal information. The first communication display symbol 60 is blinked in red.

  The alarm screen display process in S8 has a function of lighting the monitoring panel second display 20 and 20 in the same color as the alarm degree information on the alarm screen 36. With this function, the contractor can recognize the alarm state even from a remote location. Further, in this alarm state, since the boiler first indicator 16 of the third unit of the boiler 3 is lit in the same color, the contractor can easily identify which device is in the alarm state. be able to.

  The contractor who sees the alarm screen 36 knows that there is an abnormality in the gas pressure based on the information on the generated item display unit 56, and must confirm the gas supply line based on the information on the operation instruction display unit 57. Know what is not. Then, the contractor knows from the first communication display symbol 60 that the abnormality information has been communicated to the management computer of the maintenance manager. When this communication is completed, the second communication display symbol 61 Appears, knows that communication is complete, and feels secure.

  When the communication to the maintenance manager is not possible, the third communication display symbol 62 and the fourth communication symbol 63 are alternately blinked, so that the contractor can call the abnormality information by telephone. The maintenance manager is notified of the occurrence of At that time, by transmitting the code displayed on the alarm code display unit 58 to the maintenance manager, the maintenance manager can know the alarm information accurately, and can take action for quick abnormality recovery. It can be performed.

  Further, it is assumed that a plurality of the alarm information is generated. In FIG. 14, when this alarm screen 36 is displayed, if the third screen switching key section 64 is turned on in S9, the process proceeds to S10 to determine whether there is any other alarm information. Then, assuming that the alarm information to be displayed on the alarm screen 36 is the next one, the process proceeds to S8 to display alarm information relating to itself or another device. If NO is determined in S10, the process returns to S1 in FIG. 13 to display the main screen 32. If NO is determined in S9, the display of the alarm screen 36 is continued.

  If the warning information about air filter clogging is generated in the boiler 3 of the No. 2 machine in the alarm generation display process, the alarm screen 36 becomes a display screen shown in FIG. On this screen, the main display portion 37 is displayed in yellow indicating the attention information, and the first communication display symbol 60 is displayed in red.

  The contractor who has seen the alarm screen 36 knows that there is the caution information that the air filter is clogged, based on the information on the generated item display unit 56, and uses the information on the operation instruction display unit 57 to check the air filter. You can know that you have to do cleaning.

  Next, in the display of the main screen 32 in S1 of FIG. 13, when the alarm has not been recovered after the generation of the alarm information, the boiler group key unit 39, to which the device that has not recovered the alarm belongs, Either the water equipment group key part 40 or the fuel equipment group key part 41 is displayed in red or yellow according to the alarm level information. Thereby, the contractor knows that the alarm of the device of which group is not recovered.

  Now, it is assumed that the abnormality information of the gas pressure abnormality is generated in the No. 3 machine of the No. 1 to No. 8 group of the first system group of the boiler group and the alarm is not recovered. In this state, in order to display the alarm screen 36 of the alarm generating device, when the area of the boiler group key section 40 displayed in red shown in FIG. 4 is touched, the boiler group key section 40 is turned on in S12 of FIG. Is determined, and the process proceeds to the boiler group display process of S13 shown in FIG.

  Then, in S20 of FIG. 16, the first hierarchy screen 33 shown in FIG. 5 is displayed. At this time, the first system group key section 43 is displayed in red. When the first system group key section 43 is touched, YES is determined in S22, the process proceeds to S23, and the second hierarchy screen shown in FIG. 34 is displayed. In the second hierarchy screen 34, the first group key portion 45 is red. When the key portion 45 is touched, YES is determined in S25, and the third hierarchy screen 35 shown in FIG. 7 is displayed. Is done. On the third layer screen 35, the boiler key section 47 of the No. 3 machine is displayed in red. When the boiler key section 47 of the No. 3 machine is touched, YES is determined in S28, an abnormality occurrence display process similar to S3 is performed in S29, and the alarm screen 36 shown in FIG. 9 is displayed. Since the process of S29 is the same as S3, description is abbreviate | omitted.

  In S21, S24, and S27 of FIG. 16, when the second screen switching key unit 54 is touched, the previous screen is restored. Note that when the first screen switching key unit 53 is touched, processing for returning to the main screen 32 is performed, but this processing is omitted in the flowchart of FIG. In FIG. 15, the water facility display process in S14 and the fuel facility display process in S15 are the same as the boiler group display process in S13, and thus the description thereof is omitted.

  Next, the operation of the human detection sensor 22 will be described. In FIG. 13, when the abnormality occurrence display process S3 and the hierarchy display process S4 are finished, the process proceeds to S5. Here, it is determined whether there is no human detection. That is, if the presence of human detection for a predetermined time (for example, about 10 minutes) is not continued by the human detection sensor 22, YES is determined, the process proceeds to S 7, and the power supply to the monitoring panel first display 19 is stopped. As a result, although the abnormality occurrence display process S3 and the hierarchy display process S4 are performed, since the energization to the monitoring panel first display 19 is stopped, the status display by the first display 19 is performed. Is not done.

  In S5, when a person approaches and the determination that no person is detected is NO, the process proceeds to S6 and power is supplied to the monitoring panel first display 19. Thereby, the display based on the process of S3 and S4 is performed.

  In the process of S2, when it is determined that no alarm information is generated, the monitoring panel second indicators 20 and 20 are lit in green, indicating that all of the component devices are normal. Yes. Here, the process of displaying the alarm screen 36 of FIG. 9 is performed by the process of S3, and if it is determined by the process of S5 that there is no human detection, the second monitoring panel displays 20 and 20 are: The display is switched from green to red, and the monitoring panel first display 19 is in a non-display state.

  In this state, when a person approaches, the first monitoring panel display 19 immediately displays the alarm screen 36, so that the administrator or the like can quickly know the alarm contents.

  As described above, according to the embodiment, power is saved by stopping the power supply to the first monitoring panel display 19 when a person is not nearby, and a warning is displayed by the second monitoring panel displays 20 and 20. Thus, it is possible to know the presence or absence of an abnormality from a distance, and the monitoring function is maintained. In this state, when a person approaches the monitoring panel 1, the first display 19 displays the alarm screen 36, so that an administrator can immediately know the alarm phenomenon information, Can be handled promptly.
