Japanese Unexamined Patent Publication No. 2004-239581

However, the prior art described in Patent Document 1 describes the test run in detail, and it is clear that the test run requires a considerable amount of time. Although the test run itself is executed automatically, the operator must wait at the site until the test run is completed in order to confirm the success or failure of the test run.

Workers take on multiple work sites in one day, go to the sites in order, and work, but waiting for the test run period may be wasted time.

An object of the present invention is to obtain a test run management control device and a test run management control program of a cogeneration device capable of improving the monitoring work efficiency for a test run.

It is a trial run management control device, and a monitoring unit that monitors the trial run operation status executed after the installation of the cogeneration device and the monitoring status information in the monitoring unit are transmitted to at least the worker who installed the cogeneration device. It has a communication unit for doing so.

As a result, even if the worker who installed the cogeneration apparatus goes to the next work site before the end of the test run, for example, the monitoring status information regarding the end of the test run can be remotely acquired.

In the present invention, the communication unit transmits at least the test run result information indicating whether or not the test run has been normally completed as the monitoring status information in the monitoring unit, and also transmits the history information during the test run as necessary. It is characterized by that.

At the very least, by acquiring information on whether or not the test run has been completed normally, it is possible to adjust the subsequent response of the operator. Further, by transmitting the history information during the test run as needed, for example, when the test run ends abnormally, the cause of the abnormality can be quickly grasped.

The present invention is characterized in that the communication unit is a dedicated wireless communication module mounted inside the cogeneration device for transmitting and receiving information about the cogeneration device.

By using a dedicated wireless communication module, it is possible to quickly notify the monitoring status information.

The present invention is characterized in that the communication unit communicates using a network system constructed in a residence in which the cogeneration device is installed.

Even in the case of a cogeneration device that does not have a dedicated wireless communication module, the worker can receive monitoring status information remotely by using the network system constructed in the residence where the cogeneration device is installed. ..

The test run management control program according to the present invention is characterized in that it operates as a monitoring unit and a communication unit of the test run management control device in the cogeneration device.

FIG. 1 shows a state in which the installation work is completed, the test run is completed, and the house 48 can be operated steadily in cooperation with various facilities (power consumption device 24, hot water supply facility 49, etc.).

(Configuration of cogeneration apparatus 10)

The cogeneration device 10 is controlled by the controller 16.

The hot water storage unit 12 includes a hot water storage tank 32. Further, the fuel cell unit 14 generates electricity by a fuel processor 20 that takes in gas (for example, city gas 13A) from the gas supply pipe 18 to purify hydrogen, and a process centered on reforming with hydrogen and oxygen. The stack 22 for storing electricity and the electric power (direct current) stored in the stack 22 are converted into alternating current and supplied to the power consuming device 24 which is one of the energy consuming devices such as home appliances (household appliances) and lighting in the house 48. The inverter 28 is provided.

The fuel cell unit 14 needs to be cooled because it generates heat when the stack 22 generates electricity.

On the other hand, in the hot water storage unit 12, tap water or the like is taken into the hot water storage tank 32 (water supply), and the hot water supply facility 49 (shower, bath, sink, etc.) provided inside the house 48 and constitutes the energy consumption device together with the power consumption device 24. ), And for heat exchange in floor heating and air conditioning equipment, etc., it is necessary to heat (heat).

Therefore, the fuel cell unit 14 includes a heat exchanger 30, and the heat generated by the power generation in the stack 22 and the water supplied into the hot water storage tank 32 provided in the hot water storage unit 12 via the water pipe 33. We are exchanging heat with.

The water pipe 33 is provided with a heater (mainly an electric heater) (not shown), and the water pipe 33 may be heated to prevent the water pipe 33 and peripheral devices from freezing.

The inverter 28, which forms a part of the fuel cell unit 14, is connected to a switching unit 62 that controls switching with the commercial power source 60. The switching unit 62 switches the electric power supply source (electric power generated by the fuel cell unit 14 or electric power from the commercial power source 60) based on the instruction of the controller 16.

A power smart meter 63 is attached to the downstream side of the switching unit 62 as a meter for monitoring the power consumption state.

Depending on the switching by the switching unit 62, the power generated by the fuel cell unit 14 or the power from the commercial power source 60 is input to the power smart meter 63 and supplied to the power consuming device 24. There is. In other words, when the user uses the power consuming device 24, any power is supplied, so that there is no problem.

The power smart meter 63 is connected to the controller 16, and the power source is displayed on the remote control panel 46 controlled by the controller 16.

The electric power smart meter 63 analyzes the transition of the consumed electric power (power consumption, electric energy and electric energy change amount per unit time, time and time zone of consumption, etc.) to obtain the rated power consumption in advance. It is possible to identify the types of power consuming devices 24 that are known and to recognize the operating state (including on / off timing). The transition of the power consumed by the power consuming device 24 is sent to the controller 16.

A microcomputer meter 50 is attached to the gas supply pipe 18. A branch portion 18A is provided on the downstream side of the microcomputer meter 50, and one of the branch pipes 18B serves as a pipeline for supplying gas to the fuel processor 20.

The other branch pipe 18C is a pipe that supplies gas to gas appliances (stove 52, gas fan heater 54, etc.) in the house 48.

The microcomputer meter 50 has a plurality of functions of measuring the flow rate of the supplied gas and monitoring an abnormality in the gas supply. The main monitoring functions include an abnormal outflow monitoring function, a seismic sensitivity function, a pressure monitoring function, and a long-term use monitoring function.

Further, in addition to the above-mentioned main monitoring function, the microcomputer meter 50 does not actively shut off the gas supply, but is equipped with a "trace leakage monitoring function" as a safety function.

(Configuration of controller 16)

As shown in FIG. 2, the controller 16 includes a microcomputer 44 composed of a CPU 34, a RAM 36, a ROM 38, an I / O 40, and a bus 42 such as a data bus or a control bus connecting them.

The hot water storage unit control unit 12D and the fuel cell unit control unit 14D are connected to the I / O 40, and the operations of the hot water storage unit 12 and the fuel cell unit 14 are controlled by the controller 16.

A remote controller panel 46 is connected to the I / O 40. The remote control panel 46 is installed inside the target house 48 (see FIG. 1) in which the cogeneration device 10 is installed, and the user inputs a command regarding the cogeneration device 10 or displays the status of the cogeneration device 10. Has the function of

The water temperature in the hot water storage tank 32 (see FIG. 1) is classified into a plurality of temperature layers. A plurality of thermistors 51 for detecting the temperature of the stored hot water are attached to the hot water storage tank 32 at different height positions of the hot water storage tank 32, and send the detected temperature to the hot water storage unit control unit 12D.

The higher the water temperature, the higher the water temperature. Therefore, as for the water temperature in the hot water storage tank 32, the water temperature of the uppermost layer is the highest and the water temperature of the lowest layer is the lowest.

The thermistor 51 detects the temperature of each layer in the hot water storage tank 32 (for example, when classified into four layers, each of the four layers). The controller 16 controls the water supply timing, water supply amount, and the like from the water pipe 33 based on the temperature detected by the thermistor 51.

In the above, as shown in FIG. 1, the operating state after the cogeneration device 10 is installed along the outer wall of the house 48 has been described, but after the worker installs the cogeneration device 10, a trial run is indispensable. It has become.

In the test run, the worker 70 is present to confirm the normal completion of the test run, but during the test run, if the test run is executed normally, the worker 70 rarely works.

At this time, although the worker 70 is scheduled to go to the next site, it is necessary to wait at the site until the test run is completed, which may lead to a decrease in work efficiency for the test run.

Therefore, in the present embodiment, the wireless communication module 72 is incorporated in the controller 16 of the cogeneration device 10, and the communication terminal device 74 (FIGS. 2 and 4) possessed by the remote worker 70 is used by using the wireless communication module 72. (Refer to), at least, the normal end or abnormal end of the test run is notified.

In the wireless communication module 72 applied to the present embodiment, a communication technique based on a communication line standard for mobile phones such as LTE (Long Term Evolution) is applied. That is, since LTE is a communication technology created assuming the use of mobile phones outdoors, it has the advantage that radio waves are stable even when used outside. In other words, there are many base stations that send LTE radio waves, and the radio waves have a wide area with a radius of several hundred meters to several kilometers, and communication is not interrupted even between remote sites.

Hereinafter, the operation of the present embodiment will be described with reference to the flowchart of FIG.

FIG. 3 is a control flowchart showing a start routine at the start of the test run, which is started when the installation of the cogeneration device 10 is completed and the test run is started.

In step 100, it is determined whether or not it is time to acquire the progress information. It waits until the affirmative judgment is made in this step 100, and when the affirmative judgment is made, the process proceeds to step 102 to acquire the progress information of the test run.

In the next step 104, the acquired progress information is stored in time series as history information, and the process proceeds to step 106.

In step 106, it is determined whether or not the test run is completed. If a negative determination is made in step 106, the process returns to step 100, and the above steps (acquisition of progress information → storage as history information) are repeated.

If an affirmative decision is made in step 106, the process proceeds to step 108 to determine the result.

In step 108, in the case of normal end determination, the process proceeds to step 110, normal end notification processing is executed, and this routine ends.

The normal notification process is a notification to the communication terminal device 74 possessed by a worker 70 who has installed the cogeneration device 10 at the site and is currently visiting another site.

Further, in step 108, in the case of abnormality determination, the process proceeds to step 112, the history information is read, the process proceeds to step 114, the abnormality end notification and the history information transmission process are executed, and this routine ends.

That is, in the case of abnormal termination, the cogeneration device 10 is installed at the site, and the communication terminal device 74 owned by the worker 70 who is currently visiting another site is abnormally terminated. Notify the history information along with the notification.

As a result, even an operator 70 who is not at the installation site of the cogeneration apparatus 10 can grasp the cause of the abnormality to some extent.

Further, in the case of abnormal termination, the worker 70 should return to the installation site of the cogeneration device 10 or go to another worker to the installation site of the cogeneration device 10 at the break of the work at the current site. By making arrangements with, quick response is possible.

In the present embodiment, the history information is notified only at the time of abnormal termination, but the history information may be notified even at the time of normal termination.

When the installation work of the cogeneration device 10 is completed, the trial run is started. When this test run is started, the next site B is visited and the work at the site B is executed.

At this time, during the work at the site B, the wireless communication module 72 of the cogeneration device 10 at the site A notifies the communication terminal device 74 of the worker 70 at the site B of the status of the test run.

If the notification is "normal end of test run", the worker 70 can continue the work at the site B, and can efficiently proceed to the work from the site A → the site B → the site C.

Further, if the notification is "test run abnormal end", the worker 70 may divide the work of the site B and return to the site A, or request another worker to perform the work of the site A. May be good.
