Networks often use communication lines that are shared with other communication devices, and communication problems may occur due to increased traffic. Therefore, it is preferable that the amount of information sent to the server be small.

Therefore, an object of the present disclosure is to provide an equipment information transmitting device, a remote information collection system, and a status-related information transmitting method that can reduce the amount of transmitted data of status-related information based on the status of electrical equipment to be transmitted to a server. .

In order to solve the above problems, an equipment information transmitting device according to the present disclosure acquires status information of the electrical equipment from one or more electrical equipment at predetermined intervals, and transmits status-related information based on the status information to a server. An equipment information transmitting device, in at least one electrical equipment, the state information obtained from the electrical equipment at a first timing is acquired at a second timing that is the next information acquisition timing after the first timing. If the status information of the electrical equipment does not change, compare the status information acquired from the electrical equipment at the first timing with the status information of the electrical equipment acquired at the second timing to change the status information to be sent to the server. Reduce the amount of information data.

Further, the status-related information transmission method according to the present disclosure includes an equipment information transmitting device that acquires status information of one or more electrical equipment at predetermined intervals and transmits status-related information based on the status information to a server. A state-related information transmission method in which, in at least one electrical equipment, the state information obtained from the electrical equipment at a first timing is transmitted at a second timing that is the next information obtaining timing after the first timing.

FIG. 1 is a schematic configuration diagram of a remote information collection system 1 according to an embodiment of the present disclosure. As shown in FIG. 1, the remote information collection system 1 includes a plurality of lighting fixtures 10 as an example of a plurality of electrical equipment, a plurality of equipment information transmitting devices 20, and a server (data server) 50. Each facility information transmitting device 20 transmits one or more lighting equipment installed in a facility 5, such as an office building, an apartment building, a store (for example, a convenience store store, a mobile phone company store, etc.), a residence, a hospital, an art museum, etc. It may be a host computer or a gateway that manages the operations of 10. Each equipment information transmitting device 20 receives status information from one or more lighting fixtures 10 via at least one of wired and wireless communication at predetermined intervals, and transmits status related information based on the status information to the server 50. do. The server 50 stores state-related information as time-series data. This state-related information is used, for example, to find out when, where, and how the lighting fixture 10 is used, such as in facility lighting, store lighting, residential lighting, etc., and what kind of conditions are preferred.

FIG. 2 is a block diagram illustrating the exchange of information regarding the equipment information transmitting device 20. As shown in FIG. 2, each of the N first to Nth lighting fixtures 10 (N may be any natural number or 1) managed by the equipment information transmitting device 20 periodically transmits its status information ( (at predetermined intervals) to the equipment information transmitting device 20. Here, each lighting fixture 10 may be any lighting device that has a light source and emits light, such as a guide light, an emergency light, a ceiling light, a line light, a down light, a spotlight, or a pendant light. be done.

The equipment information transmitting device 20 includes a control device 25, a receiving section 30, and a transmitting section 35. The control device 25 is preferably configured by a computer, for example, a microcomputer, and includes a control section 26 and a storage section 28. The control section 26 includes a data comparison section 26a, a data conversion section 26b, and a transmission control section 26c. The control unit 26, that is, the processor includes, for example, a CPU (Central Processing Unit). Furthermore, the storage unit 28 is composed of a nonvolatile memory such as a ROM (Read Only Memory) and a volatile memory such as a RAM (Random Access Memory). The CPU reads and executes programs etc. stored in the storage unit 28 in advance. Furthermore, the nonvolatile memory stores in advance a control program, predetermined threshold values, and the like. Further, the volatile memory temporarily stores read programs and processing data. For example, the storage unit 28 stores a control program that defines the operations of the data comparison unit 26a, the data conversion unit 26b, and the transmission control unit 26c.

The receiving unit 30 includes a receiving port to which a cable for transmitting wired signals is connected and a receiving antenna for receiving wireless signals, and receives status information from each lighting fixture 10. Further, the status information is processed by the operations of the data comparison unit 26a and the data conversion unit 26b, and the transmission unit 35 transmits the status related information, which is the processed information, to the server 50 under the control of the transmission control unit 26c. The transmitting unit 35 includes a transmitting port to which a cable for transmitting wired signals is connected, and a transmitting antenna for transmitting wireless signals. The specific operations of the data comparison section and the data conversion section will be described in detail below.

Next, the purpose of the present disclosure and operations to achieve the purpose will be described in detail. The equipment information transmitting device 20 checks the usage of the lighting equipment 10 and records the state log of the lighting equipment 10 in order to find out "at what times, in what rooms, and what kind of brightness and color temperature is preferred?" After acquiring the series data, the time series data is processed to create state related information, and the created state related information is transmitted to the server 50.

Figure 3 is a table showing an example of time series data of status logs acquired in a remote information collection system equipped with three lighting fixtures. As shown in Figure 3, various data including "time" are acquired. In addition, the various data may include, for example, data type, number of repetitions, fixture number, fixture type, room type, dimming rate, color temperature, etc. This data includes a mixture of qualitative data representing the type of room and fixture, and quantitative data representing the dimming rate and color temperature, but both are acquired as status logs as digital data.

When the lighting is turned on, it is often adjusted to suit one's preference, and then the lighting remains in that state for a while. Of course, changes may be made later depending on preference, but changes are often made after the same state has continued for a while. FIG. 4 is a table explaining such a situation, and is a table showing an example of time-series data of a status log acquired by the equipment information transmitting device from 0:00 a.m. to 4:30 a.m. in the early morning for one lighting fixture. be.

In the example shown in FIG. 4, from 0:00 a.m. to 3:40 a.m. early in the morning, the facility information transmitting device acquires status information about the same lighting state from the lighting equipment every five minutes for a long period of time. Thereafter, at 3:42, the state of the lighting fixture was switched to the off state by the user, and the equipment information transmitting device acquired state information of a different state (unlit state) from the lighting fixture at 3:45. Further, thereafter, until 4:30, the equipment information transmitting device acquires the same status information of the unlit state from the lighting equipment every 5 minutes.

Networks often use communication lines that are shared with other communication devices. Therefore, if the equipment information transmitting device sends a large amount of status-related information to the server every 5 minutes in a situation where the same status continues for a long time, communication problems are likely to occur due to increased traffic. I don't like it.

The technology of the present disclosure was discovered to solve this problem. Next, operations that can solve such problems will be explained in detail. In the technology of the present disclosure, when the receiving unit 30 of the equipment information transmitting device 20 acquires status information from each lighting fixture 10, the storage unit 28 of the equipment information transmitting device 20 stores the status information for each lighting fixture 10. .

FIG. 5(a) is a table showing an example of time-series data of the status log of status information acquired by one lighting fixture 10 of the equipment information transmitting device 20, and FIG. It is a table showing an example of state information stored for the above-mentioned one lighting fixture 10 regarding series data.

As shown in FIG. 5(a), in this example, the dimming rate and color temperature of the lighting fixture 10 do not change from 10:00 to 10:15 on October 1, 2019, and at 10:20 At 10:35, the dimming rate decreased from 100 to 80, and furthermore, at 10:35, the color temperature decreased from 4,500 to 3,000. At this time, in the operation of the present disclosure, as shown in FIG. 5(b), when the equipment information transmitting device 20 acquires different state information, the storage unit 28 instantly replaces the changed state information with the state information before the change. overwrite and memorize it. Specifically, in the example shown in FIG. 5(a), the storage unit 28 first stores the state information at 10:00 on October 1, 2019, and stores the changed state information at 10:20. The status information before the change is overwritten and stored, and the status information changed at 10:35 is also overwritten and stored over the status information before the change.

Next, data that the equipment information transmitting device 20 transmits to the server 50 will be explained. FIG. 6(a) is a table showing an example of transmission data of a reference example transmitted to the server regarding the acquired status information explained in FIG. 5(a). Further, FIG. 6(b) is a table showing an example of transmission data of the present disclosure transmitted to the server 50 regarding the acquired status information and stored status information described in FIG. 5(a).

As shown in FIG. 6(a), in the transmission method of the reference example, even if the same status information as the status information acquired at the previous reception timing is acquired at the next reception timing, the equipment information transmission device Specifically, all information including the appliance number, appliance type, room type, dimming rate, and color temperature is sent to the server.

On the other hand, as shown in FIG. 6(b), in the transmission method of the example of the present disclosure, when the same status information as the status information acquired at the previous reception timing is acquired at the next reception timing, the equipment information The transmitting device 20 transmits only information about the appliance number to the server 50. Therefore, the amount of data to be transmitted can be significantly reduced. This equipment number information is an example of equipment identification information and also an example of status related information.

FIG. 7 is a flowchart of an example of control performed by the control device 25 of the equipment information transmitting device 20 to reduce the amount of transmitted information. Referring to FIG. 7, when the remote information collection system 1 is constructed, control starts, and in step S1, the receiving unit 30 of the equipment information transmitting device 20 receives status information (status data) from each lighting fixture 10. For each lighting fixture 10, it is determined whether the status information acquired in step S2 is the first status information.

If a positive judgment is made in step S2, the process proceeds to step S3, where the storage unit 28 stores the status information, and then in step S4, the status information is transmitted to the server 50. At this time, the status-related information matches the status information. When step S4 is completed, control is returned, and steps S1 and onward are repeated.

On the other hand, if a negative judgment is made in step S2, the process proceeds to step S5, where the data comparison unit 26a (see FIG. 2) of the control unit 26 performs a one-to-one comparison of the acquired status information for each lighting device 10 with the status information of the corresponding lighting device 10 stored in the memory unit 28, and in step S6, the data comparison unit 26a judges whether the acquired status information is the same as the status information of the corresponding lighting device 10 stored in the memory unit 28.

If an affirmative determination is made in step S6, the process proceeds to step S7, where the data converter 26b (see FIG. 2) converts the acquired state information into state-related information with a small amount of data. For example, the status-related information includes only lighting identification information (identification data) that can identify lighting fixtures whose status information has not changed. Here, the lighting specific information includes, for example, information on the number of repetitions when status information with no change is repeated, identification information of the lighting fixture 10 whose status information has not changed, and status information with no change. The information may include at least one of time information based on the time when the status information was acquired, and time information based on the time when the status information with no change was acquired. Further, the identification information may be any information as long as it can identify each lighting fixture with respect to other electrical equipment (for example, lighting fixtures, air conditioners, etc.), such as a MAC address (Media Access Control address). , barcode information, RF (radio frequency) tag, product number information, IP address, manufacturing number, etc.

When step S7 is completed, the process moves to step S4, and the transmitting unit 35 of the equipment information transmitting device 20 transmits the state-related information whose data amount has been reduced to the server 50 under the control of the transmitting control unit 26c (see FIG. 2). After that, control returns. On the other hand, if a negative determination is made in step S6, the process proceeds to step S8, where the storage unit 28 overwrites and updates new status information, and under the control of the transmission control unit 26c, the transmission unit 35 of the equipment information transmission device 20 sends new status information to the server 50, after which control returns.

As described above, the equipment information transmitting device 20 acquires status information of the lighting fixture 10 from one or more lighting fixtures 10 at predetermined intervals, and transmits status-related information based on the status information to the server 50. Further, in at least one lighting fixture 10, the status information of the lighting fixture 10 acquired at the second timing, which is the information acquisition timing following the first timing, is different from the status information acquired from the lighting fixture 10 at the first timing. If there is no change, the status related information to be sent to the server 50 in comparison with the status information acquired from the lighting fixture 10 at the first timing and the case where the status information of the lighting fixture 10 acquired at the second timing changes. Reduce the amount of data.

This can reduce traffic increases and reduce or prevent communication problems.

Further, if the status information acquired at the second timing is the same as the status information acquired at the first timing, the status related information is configured to include equipment identification information that can identify the lighting fixture 10 whose status information has not changed. Then, the equipment identification information may be sent to the server 50.

If the status information acquired at the second timing is the same as the status information acquired at the first timing, an alternative method may be to significantly reduce the amount of transmitted data without transmitting the information to the server. be able to. However, in this case, from the server side, it is necessary to determine whether the information is not being sent because the status information (data) is the same, or if there is some kind of trouble during data communication and the information is not being sent. I can't.

In contrast, according to the present configuration, even if the status information acquired at the second timing is the same as the status information acquired at the first timing, the server 50 receives the equipment identification information. Therefore, not only can the amount of data transmitted to the server 50 be reduced when the same status information is acquired at the second timing as that acquired at the first timing, but the server 50 can recognize that the status information is the same. Note that in the flow shown in FIG. 7, the status-related information is limited to equipment identification information that can identify the lighting fixture 10 whose status information has not changed, and only the equipment identification information is transmitted to the server 50, but the status-related information may include other information in addition to the equipment identification information.

The equipment identification information may also include at least one of information on the number of repetitions when the unchanged status information is repeated, identification information of the lighting fixture 10 whose status information has not changed, time information based on the time when the unchanged status information was transmitted, and time information based on the time when the unchanged status information was acquired.

According to this configuration, not only can the lighting fixture 10 be identified, but also state-related information with a small amount of data can be easily generated.

The electrical equipment may also be a lighting fixture 10 having a light source that emits light, and the equipment information transmission device 20 may acquire status information only from the lighting fixture 10.

According to this configuration, it is possible to investigate and analyze when, where, and how the lighting fixture 10 is used, and what kind of situations are preferred.

Further, the remote information collection system 1 of the present disclosure includes one or more lighting fixtures 10, an equipment information transmitting device 20 that acquires state information of the lighting fixtures 10 at predetermined intervals, and a state based on the status information from the equipment information transmitting device 20. It includes a server 50 that acquires related information.

Therefore, the status information of the lighting fixture 10 can be stored in the server 50 in chronological order with a small amount of transmitted data. Therefore, a predetermined person can check the time-series status information of the lighting equipment 10 while suppressing or preventing the occurrence of communication failures.

Further, the status-related information transmission method of the present disclosure acquires status information of one or more lighting fixtures 10 at predetermined intervals, and transmits status-related information based on the status information to the server 50. This is a method for transmitting state-related information in the transmitting device 20. Furthermore, in the state-related information transmission method of the present disclosure, in at least one lighting fixture 10, the state information acquired from the lighting fixture 10 at the first timing is set at a second timing that is the next information acquisition timing after the first timing. If the status information of the lighting fixture 10 acquired at the second timing does not change, the status information of the lighting fixture 10 acquired at the second timing changes with respect to the status information acquired from the lighting fixture 10 at the first timing. In comparison, the amount of state-related information transmitted to the server 50 is reduced.

According to the state-related information transmission method of the present disclosure, an increase in traffic can be suppressed, and the occurrence of communication problems can be suppressed or prevented.

Note that this disclosure is not limited to the above-described embodiment and its modified examples, and various improvements and modifications are possible within the scope of the claims of this application and their equivalents.

For example, in the above embodiment, if the status information acquired at the second timing is the same as the status information acquired at the first timing, the status-related information is limited to equipment-specific information that can identify the lighting fixture 10 whose status information has not changed, and only the equipment-specific information is transmitted to the server 50. However, if the status information acquired at the second timing is the same as the status information acquired at the first timing, it is not necessary to transmit the status-related information to the server.

FIG. 8 is a flowchart of control in the control device 25 of the equipment information transmitting device 20 that implements the modification. Note that in FIG. 8, the same operations as in FIG. 7 are given the same step numbers as in FIG. 7, and the explanation of the operations will be omitted. In the control of this modification, only the operation when an affirmative determination is made in step S6 differs from the control shown in FIG.

In other words, if a positive judgment is made in step S6, the equipment information transmission device 20 does not transmit any information to the server 50, and control is simply returned, and step S1 and subsequent steps are repeated. According to this modified example, if the status information acquired at the second timing is the same as the status information acquired at the first timing, no information is transmitted to the server 50 at all, and the amount of data communication can be significantly reduced.

Further, in the above embodiment, a case has been described in which one or more electrical equipment is composed of only one or more lighting fixtures 10. However, the one or more electrical equipment does not need to be composed only of the one or more lighting equipment 10, and may be composed of one or more lighting equipment and one or more electrical equipment that is not a lighting equipment, or the lighting equipment It may consist only of one or more electrical equipment other than the above. Here, electrical equipment that is not lighting equipment may be any electrical equipment that cannot emit light, and examples of electrical equipment that is not lighting equipment include alarms, fire alarms, smoke exhaust equipment, elevators, escalators, and air conditioners. At least one of them may be included.

Furthermore, as explained in paragraph [0013], the lighting equipment managed by the technology of the present disclosure may be any lighting equipment, but in the case of a lighting equipment used for a special purpose, the conditions related to that usage Preferably, the relevant information is stored on the server. For example, the lighting equipment managed by the technology of the present disclosure may be any lighting equipment, so it does not have to be a lighting equipment used indoors. It may be a street light, road light, or security light.

In the case of outdoor lighting fixtures that are subject to significant deterioration over time and may be damaged by contact with objects (e.g., people, bicycles, or automobiles), it is of course necessary to perform fault detection, i.e., monitoring of the lighting status, as described in detail with reference to Figure 4 for indoor lighting fixtures. Furthermore, if the most recent data, such as the most recent power consumption data, the most recent lighting status data, or the most recent power data, can be identified, this makes it easier to smoothly carry out recovery and also enables failure analysis, which is preferable.

FIG. 9 is an example of a flowchart illustrating a processing procedure of the remote information collection system 1 that is not limited to such uses and allows storing immediately preceding data in a server. When the remote information collection system 1 is constructed, a processing procedure starts, and in step S11, the control device 25 of the equipment information transmitting device 20 receives N (N is any natural number) from any of the lighting equipment at the reception timing. Determine whether or not a normal signal could not be obtained consecutively. Here, the case where a normal signal cannot be received includes, for example, a case where the signal itself cannot be received, a case where status information that is supposed to be included in the received signal is not included, and the like. Furthermore, when N is 1, the determination is not whether or not normal signals could not be acquired continuously, but whether or not normal signals were not acquired at any reception timing.

If a negative determination is made in step S11, step S11 is repeated. On the other hand, if an affirmative determination is made in step S11, the process proceeds to step S12, in which the control device 25 stores the abnormal lighting equipment in the storage unit 28 and is able to acquire a normal signal N times in a row. The state information contained in the last normal signal immediately before the abnormal state occurred, such as time information, electric energy information, power information, lighting state information, dimming information, etc., is identified.

Then, in step S13 after step S12, the equipment information transmitting device 20 links the one or more pieces of status information with the identification information (this may also be used as status information) of the lighting fixture that has become abnormal. , to the server 50. In step S14 after step S13, the server 50 receives (obtains) information linked to the identification information from the equipment information transmitting device 20, and stores it in the storage section of the server 50. In the case of this modification, each of the equipment information transmitting device 20 and the server 50 has a signal transmitting section and a receiving section, and is capable of transmitting and receiving signals. In the next step S15, the server 50 transmits information indicating that the information associated with the identification information has been stored to the equipment information transmitting device 20.

In the next step S16, when the control device 25 of the equipment information transmission device 20 recognizes that the server 50 has stored information linked to the identification information based on the signal from the server 50, the processing procedure is returned. According to this modified example, a person can access the server 50 to obtain the state information of the broken lighting fixture immediately before the failure. Therefore, the cause of the failure can be analyzed, and the lighting fixture can be quickly restored. In particular, when the lighting fixture is a lighting fixture installed outdoors, such as a street light, road light, or security light, the location information of the lighting fixture and, in some cases, the information on the time of installation are important information. Therefore, in the case of such a lighting fixture, at least one of the location information obtained by a person using a GPS receiver or the like and the information on the time of installation of the lighting fixture obtained by a person can be transmitted to the server 50 via the equipment information transmission device 20 using an information device (e.g., a smartphone, tablet, or personal computer) by a person, or directly to the server 50, and at least one of the information can be stored in the server 50 in a state linked to the identification information of the lighting fixture. Alternatively, in the case of such lighting fixtures, the lighting fixture may transmit the location information acquired by the GPS receiver built into the lighting fixture to the server 50 via the equipment information transmission device 20, and the location information may be stored in the server 50 in a state linked to the identification information of the lighting fixture. Note that in the case of lighting fixtures installed outdoors, such as street lights, road lights, security lights, etc., and a luminaire including a structure (e.g., a power supply circuit, wiring, etc.) necessary for emitting light from a light-emitting unit is fixed to a predetermined position using a pole, the lighting device includes the luminaire and the pole. Therefore, when a lighting fixture includes a GPS receiver and a pole, the GPS receiver may be disposed in the lighting fixture or in the pole.

Furthermore, in the flowchart using FIG. 9, the case where the electrical equipment is a lighting fixture, particularly the case where it is a lighting fixture installed outdoors, has been explained, but the flowchart using FIG. 9 can be applied to: Not limited to lighting equipment. Specifically, in paragraph [0049], the electrical equipment that is not a lighting equipment to which the technology of the present disclosure can be applied may be any electrical equipment that cannot emit light, and the electrical equipment that is not a lighting equipment includes, for example, an alarm, a fire alarm, It was disclosed that at least one of a smoke extraction facility, an elevator, an escalator, and an air conditioner may be included. Here, the flowchart using FIG. 9 may be applied to any electrical equipment other than lighting equipment, such as an environmental sensor that can detect environmental information, such as a temperature sensor, humidity sensor, water level sensor, rain detection sensor, illuminance sensor, etc. It may also be applied to sensors, etc. Alternatively, the flowchart using FIG. 9 may be applied to a solar power generation device, a wind power generation device, a wave power generation device, a tidal current power generation device, etc. Alternatively, the flowchart using FIG. 9 may be used for a monitoring device that stores at least one of image information (image data) and video information (video data) in a server, such as a fixed-point imaging device that monitors traffic volume, or for crime prevention purposes. The invention may also be applied to crime prevention photographing devices, etc.

Further, the remote information collection system of the present disclosure may exchange data in one direction, but may also exchange data in both directions. Here, when exchanging signals in both directions in the remote information collection system, the exchange of information between the electrical equipment and the equipment information transmitting device is changed to the exchange of information in one direction from the electrical equipment to the equipment information transmitting device. The exchange of information between the facility information transmitting device and the server may be bidirectional information exchange using mutual transmitting and receiving units. Alternatively, in a remote information collection system, when two-way signals are exchanged, the information exchange between at least one electrical equipment and the equipment information transmitting device is a two-way information exchange using mutual transmitting and receiving units. On the other hand, the exchange of information between the equipment information transmitting device and the server may be one-way information exchange from the equipment information transmitting device to the server. Alternatively, in a remote information collection system, when two-way signals are exchanged, the information exchange between at least one electrical equipment and the equipment information transmitting device is a two-way information exchange using mutual transmitting and receiving units. In addition, the exchange of information between the equipment information transmitting device and the server may also be bidirectional information exchange using mutual transmitting/receiving units.

Next, an example of bidirectional information exchange in the remote information collection system will be described. For example, when newly installing street lights or road lights in the same area (for example, a town), the lighting control of the street lights or road lights is often performed in the same way in the same area. In such a case, it may be preferable if lighting information of existing street lights and road lights in the same area can be smoothly acquired and used for controlling the lighting of additionally installed street lights and road lights.

Figure 10 is a diagram explaining the two-way information exchange that is preferable in such a case. First, in such a case, as shown in the flowchart in Figure 10 (a), when each lighting fixture is incorporated into the remote information collection system, in step S21, the lighting fixture may transmit information about dimming control (including simple lighting control) to the server via the equipment information transmission device, and in step S22, the server may store the information about dimming control in association with the identification information of the corresponding lighting fixture.
