Description

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

  First, the background that led to the present invention will be described. For 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 and Patent Document 2)

  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 number of components constituting the boiler room is greatly increased in the number of boilers and the types and numbers of the auxiliary devices. , It has become difficult to grasp what is happening. 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.

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, and the same alarm generation display process as S3 is performed in S29, and the alarm screen 36 shown in FIG. 10 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. 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 alarm 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. Thereby, although the alarm occurrence display process S3 and the hierarchy display process S4 are performed, since the energization to the first monitoring panel 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 indicator 20, 20 lights up 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.

  Next, the abnormality notification function (5) to the contractor will be described. The monitoring panel 1 of this embodiment has a function of notifying the contractor when the alarm information is received from itself or from the boiler room constituent device. As the reporting means, it has an output (modem report) and / or a contact output (contact report) to the contractor's mobile phone (not shown). Then, which means is used can be set by the contractor for each type of alarm information to be generated.

  In addition, the contact output means includes a plurality of contacts, and the contacts to be used can be arbitrarily changed according to the generated alarm information. The contact is provided so that it can be output to a buzzer (not shown) or a display lamp (not shown) installed in a separate chamber from the boiler chamber 2. For example, it is possible to make arbitrary settings such as outputting alarm information of the boiler group to the first contact and outputting alarm information of the water equipment to the second contact.

  In addition to transmitting alarm information using a mail function, the report to the mobile phone is registered in advance with the telephone number and name of the monitor panel 1 in the contractor's mobile phone. The alarm information itself is not transmitted by using a method of immediately disconnecting the telephone after the person's mobile phone is called and notifying the destination, but it may also be used to notify that some sort of alarm has occurred. Also by this method, the contractor can know that there has been a call notification from the monitoring board, that is, some alarm information has been issued.

  Further, the earthquake determination function (6) will be described. All or a part (plural units) of the boiler 3 installed in the boiler chamber 2 is provided with an earthquake detection sensor. When each of the boilers 3 determines that there is an earthquake by the operation of the earthquake detection sensor, it communicates to that effect to the monitoring panel 1. When all or a certain percentage (for example, 80%) of the earthquake detection sensors output a signal indicating that there is an earthquake, the monitoring panel 1 determines that there is an earthquake.

  Regarding the processing after this determination, the contractor can make the following settings, and the monitoring panel 1 operates according to the settings. The first setting is a setting of “display” or “not display” of “with earthquake” in the monitoring panel 1. When the “display” is set, the second state is displayed only as notification information, the abnormality information is displayed, and all the boilers 3 are set in a combustion standby (or combustion stop) state. The state can be selectively set. Further, the ratio that the monitoring panel 1 determines that there is an earthquake can be adjusted by the contractor.
