[0010] The embodiments will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are denoted by the same reference numerals. Duplicate descriptions of the parts may be simplified or omitted.

[0011] Embodiment Fig. 1 is a diagram showing an example of the configuration of a building equipment management device according to an embodiment. Fig. 1 shows, as building equipment, a boiler 10, an air conditioning equipment 12, an electrical equipment 14, a water supply and drainage equipment 16, and a disaster prevention monitoring equipment 18. The electrical equipment 14 is, for example, a substation equipment. In another example, the building equipment includes electrical communication equipment, elevator equipment, a pump, a blower, an air conditioning heat source equipment, and the like. In yet another example, the building equipment includes other building equipment.

[0012] The monitoring system 20 is a system that monitors the operation status of building facilities. According to one example, the monitoring system 20 can be provided in the form of a monitoring panel. The monitoring system 20 collectively manages information related to the operation status of the building facilities. According to one example, the monitoring system 20 is provided with information related to failures of the building facilities in addition to information related to the operation status of the building facilities.

[0013] The monitoring system 20 is configured to be able to communicate with the base station 30 via a wired or wireless connection. Information is provided from the monitoring system 20 to a server 32 via the base station 30. If the information is information relating to a failure of building facilities, the information is transmitted from the server 32 to a terminal device 34. The terminal device 34 is, for example, a terminal such as a personal computer, smartphone, or tablet that can be easily and frequently accessed by the building manager.

[0014] FIG. 2 is a flowchart showing the process for notifying the building manager of fault information about building equipment. First, in step S1, it is determined whether the monitoring system 20 has detected a fault in the building equipment. If a fault is detected, the process proceeds to step S2. In step S2, fault information about the building equipment is input to a dry contact converter. The dry contact converter is a device that receives a non-voltage contact signal (maximum of two points) and outputs a signal in accordance with the Sigfox communication standard. In step S3, the dry contact converter outputs the fault information about the building equipment as a signal in accordance with the Sigfox communication standard.

[0015] Next, in step S4, the Sigfox communication standard signal is received at the nearest Sigfox base station. The nearest Sigfox base station is the base station for Sigfox installed nationwide that is installed nearest to the dry contact converter.

[0016] Next, in step S5, the above-mentioned fault information is provided from the nearest Sigfox base station to the Sigfox cloud server. The Sigfox cloud server is a server that manages Sigfox communication. For example, mail destination settings, mail text settings, transmission conditions, etc. can be set in this server. If the fault information received by the Sigfox cloud server is determined to be such that an alarm occurrence mail should be sent according to the settings in the server, the process proceeds to step S6, where the server sends an alarm occurrence mail to the terminal device, which is received by the administrator. The alarm occurrence mail can be replaced by another method, such as, for example, an alarm screen display or a voice notification. Any method can be adopted for notifying the administrator of the fault information.

[0017] In this way, by directly and timely transmitting information about malfunctions in building facilities to the manager's terminal device, the manager can take prompt action. According to one example, the manager who receives the malfunction information can arrange for a contractor to deal with the malfunctioning facility or share the malfunction information with relevant people in the building.

[0018] The building equipment management device according to this embodiment has a function of notifying the manager of the signs of failure in the building equipment. The technology related to such failure prediction will be described with reference to Figures 3 and 4. In either example, the communication method described with reference to Figure 2 can be adopted.

[0019] FIG. 3 is a flow chart for realizing the integrated time type of failure sign detection. First, in step S10, it is determined whether the integrated operating time of the building equipment has reached a predetermined value. According to one example, the monitoring system 20 connected to the building equipment outputs a time lapse signal when the integrated operating time of the building equipment reaches a predetermined time. For example, an integrated operating time at which the possibility of failure is at least a certain level is set for each building equipment. According to one example, the integrated operating time at which the possibility of failure is at least a certain level can be the expiration date set by the Measurement Act for batteries / storage batteries or meters (electricity, water, gas). For example, if the expiration date is 5 years, the integrated operating time at which the possibility of failure is at least a certain level is 5 years x 365 days x 24 hours = 43,800 hours. Then, the monitoring system 20 records the integrated operating time for each building equipment, and determines at any time whether the integrated operating time has reached a predetermined time (i.e., the integrated operating time at which the possibility of failure is at least a certain level). When the cumulative operating time of a certain building facility reaches a predetermined time, the monitoring system 20 proceeds to step S12 and outputs a time elapsed signal. According to one example, the time elapsed signal includes information on the target building facility, the cumulative operating time of the building facility, and the predetermined cumulative operating time. On the other hand, if it is determined that the cumulative operating time of the building facility has not reached the predetermined time, the monitoring system 20 proceeds to step S11 and determines that the probability of failure occurring in all building facilities is low.

[0020] The time lapse signal is received by an external device. In one example, the external device is a base station and a server. The base station and the server receive the time lapse signal and transmit to the terminal device warning information including the receipt of the time lapse signal and the building equipment that caused the transmission of the time lapse signal. By receiving the warning information from the terminal device, the manager can perform maintenance or replace parts of the specific building equipment, as described as step S13.

[0021] According to one example, the time elapse signal includes information regarding the fact that the accumulated operating time of a certain building equipment has reached a predetermined time, and the useful life of the building equipment that triggered the issuance of the time elapse signal. For example, this "predetermined time" can be a time shorter than the useful life. By comparing the "predetermined time" regarding the accumulated operating time with the useful life, it is possible to know how much time is left from receiving this warning information until the useful life is reached. In this case, the warning information can include information regarding the useful life of the building equipment.

[0022] FIG. 4 is a flow chart for realizing the operation data reference type failure sign detection. First, in step S21, the monitoring system 20 acquires operation data of the building equipment. The operation data is data obtained during the operation of the building equipment, and the value gradually changes with the transition from a normal state to a failure state. In one example, the operation data is data on the temperature, pressure, vibration, or water quality of the boiler. In another example, the operation data is the components of the exhaust gas of the boiler. In yet another example, the operation data is data on the temperature, pressure, or vibration of the air conditioner. In yet another example, the operation data is the leakage current (leakage), load current, temperature (heat generation monitoring), voltage, or insulation resistance value of the substation equipment. In yet another example, the operation data is the head, flow rate, load current, voltage, leakage current (leakage), or insulation resistance value of the pump. In yet another example, the operation data is the static pressure, air volume, load current, voltage, leakage current (leakage), or insulation resistance value of the blower. According to yet another example, the operational data is the return flow rate, temperature, or heat load of the air conditioning heat source equipment.

[0023] Next, in step S22, the monitoring system 20 determines whether the operation data has exceeded a predetermined range. The predetermined range of the operation data is determined, for example, by a prior experiment. For example, the relationship between the boiler temperature and a failure is investigated, and an association is made between the temperature exceeding a predetermined range and a failure being imminent. In another example, the relationship between the boiler pressure and a failure is investigated, and an association is made between the pressure exceeding a predetermined range and a failure being imminent. In another example, the relationship between the boiler exhaust gas components and a failure is investigated, and an association is made between the exhaust gas components exceeding a certain range and a failure being imminent. Similarly, a "predetermined range" is determined for the vibration or water quality of the boiler.

[0024] Next, when the monitoring system connected to the building equipment determines that the operation data of the building equipment has exceeded the predetermined range, the process proceeds to step S24, and the monitoring system 20 outputs a failure prediction signal. On the other hand, when it determines that all the operation data related to the building equipment has not exceeded the predetermined range, the process proceeds to step S23, and it is determined that there are no failure predictions.

[0025] When the external device receives the failure prediction signal, the external device transmits failure prediction information to the terminal device, the failure prediction information including the fact that the failure prediction signal was received and the building equipment that caused the failure prediction signal to be transmitted. Examples of the external device are a base station and a server. According to one example, the failure prediction information can include information regarding the expected time of failure if the building equipment is continuously used. This allows the manager to know the existence of building equipment that shows a failure prediction, and further to know whether the problem should be dealt with immediately or whether the problem can be dealt with with some time to spare.

[0026] Both the examples in Figures 3 and 4 enable the prediction of failures in building facilities, so that the manager can prevent failures by performing maintenance or replacing parts on the building facilities that have been predicted to fail. Avoiding failures contributes to maintaining convenience for building users.

[0027] FIG. 5 is a diagram showing an example of the configuration of the monitoring system 20. The monitoring system 20 includes a receiving device 70a, a processing circuit 70b, and a transmitting device 70c. For example, fault information, information for calculating the accumulated operating time, and information on the operating data are transmitted to the receiving device 70a. The above-mentioned functions performed in the monitoring system 20 are realized by the processing circuit 70b. That is, in the processing circuit, it is determined whether the accumulated operating time of the building equipment has reached a predetermined time, and if the time has been reached, a time elapsed signal is output. According to another example, it is determined whether the operating data of the building equipment has exceeded a predetermined range, and if it is determined that the operating data has exceeded the predetermined time, a fault prediction signal is output. The processing circuit 70b may be dedicated hardware or may be a CPU (also called a central processing unit, processing device, arithmetic device, microprocessor, microcomputer, processor, or DSP) that executes a program stored in a memory. When the processing circuit is dedicated hardware, the processing circuit may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination of these. The determination and the signal output may be realized by separate processing circuits, or may be realized together by a processing circuit.

[0028] FIG. 6 shows a configuration example of the monitoring system 20 in the case where the processing circuit is a CPU. In this case, each function of the monitoring system 20 is realized by software or a combination of software and firmware. The software or firmware is written as a program and stored in the memory 80c. The processor 80b realizes each function by reading and executing the program stored in the memory 80c. That is, the memory 80c is provided with a program that, when executed by the processing circuit of FIG. 6, results in the execution of steps S10, S11, and S12 in FIG. 3. According to another example, the memory 80c is provided with a program that, when executed by the processing circuit of FIG. 6, results in the execution of steps S21, S22, S23, and S24 in FIG. 4. These programs can also be said to cause a computer to execute the procedures and methods of steps S10, S11, and S12 or steps S21, S22, S23, and S24. Here, the memory corresponds to, for example, non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, etc., magnetic disk, flexible disk, optical disk, compact disk, mini disk, DVD, etc. Of course, some of the above functions may be realized by hardware and some by software or firmware.
