Description
Technical Field
The present invention relates to a beacon lighting detection method and device for accurately grasping operation information of equipment using lighting information of a beacon mounted on production equipment.
Background
In recent years, various kinds of information in a factory are collected, and arrangement for improving productivity and quality is performed using the information. Conventionally, in order to grasp operation information of production equipment, there is a method of displaying the status of the equipment by installing a beacon in each equipment and displaying a lighting pattern of a lamp based on the beacon. The operator checks the lighting of the beacon to recognize the state of the equipment such as an emergency stop due to an error, and immediately responds to the situation to expect an improvement in the operation rate.
However, this method is based on visual observation by an operator, and it is difficult to constantly grasp the operation state in a factory where labor saving is increased, and it is difficult to visualize the operation rate of the production line or the entire factory and to perform operation analysis because information is not digitized.
As a method for solving this problem, an arrangement is being made in which lighting information of the beacon of each device is automatically acquired, the operation state is accurately grasped in real time, and the operation information of each device is converted into data. As a method of acquiring lighting information of the beacon, there is a method of detecting a lighting state of the beacon by an optical sensor (patent document 1). With this method, the operation information of the production facility can be accurately grasped as data in real time. Fig. 6 is a diagram illustrating a conventional beacon lighting detection method. The optical sensors 103 are disposed in the vicinity of the display lamps 102 of the beacon 101, and information of the optical sensors 103 is wirelessly transmitted from the transmitter 104 to the receiver 105. By processing the information transmitted to the receiver 105 into operation information by the data processing device 106, accurate operation state data of the production facility is realized.
However, in the conventional beacon lighting detection method, if it is assumed that the method is introduced into an existing production line including a large number of production facilities, information is converted into wireless information, but a large-scale wiring work for supplying power to drive the optical sensor and the wireless system is required. However, when the operation is grasped and information acquisition is performed in real time at a high frequency, the battery is consumed quickly, and a large amount of batteries must be frequently replaced.
In contrast, there is a power supply method that does not require power wiring or battery replacement by applying energy harvesting technology that has been developed in recent years. The method includes, for example, the following methods: a method of generating power using light-based power generation technology using indoor light of a factory and supplying the power to a sensor and a wireless system; or a method of wirelessly supplying not only information but also power by radio waves. Thus, operation sensing without wiring and battery replacement can be realized.

However, in the signal tower lighting detection method using the conventional energy collection technology, the generated power by the indoor light is weak, and a large-area power generation panel is required to recover sufficient power. Further, the brightness of indoor light varies depending on factories or places, and a difference occurs in electric power that can be collected. On the other hand, in the method of wirelessly supplying electric power, the recoverable electric power transmission wave decreases according to the distance from the electric power transmitter. In a wide space such as a factory, since it is assumed that the distance between the power transmitter and the signal tower is far, the electric power that can be recovered is very weak, and it is difficult to supply electric power for collecting data in real time.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Fig. 1 is a diagram showing a beacon lighting detection device and a beacon in the present embodiment.
The beacon 101 changes the lighting state of each of the indicator lamps 102 of the plurality of indicator lamps according to the operating state of the production facility 90, and can grasp the operating state of the production facility 90 from the state.
A lighting detection sensor 201, which functions as an example of a lighting detection device and is provided in the beacon unit 101, detects the lighting state of each display lamp 102 of the beacon unit 101 and outputs lighting information.
The transceiver 204 receives lighting information of each display lamp 102 from the lighting detection sensor 201.
The transceiver 204 includes an antenna 202 and an oscillation control unit 203. The wireless information communication 81 is performed between the transceiver 204 and the lighting detection sensor 201, the lighting information of each display lamp 102 is transmitted from the transceiver 204 to the data processing device 106, and the operation information of the production facility 90 in which the beacon 101 is installed is acquired by the data processing device 106.
The transceiver 204 performs generation and control of high-frequency power by the oscillation control section 203, and performs transmission and reception of radio waves 82 with the lighting detection sensor 201 by the antenna 202.
The lighting detection sensor 201 includes at least one antenna 205, a circuit board 206 having a lighting detection control section 99 that performs wireless power feeding, information acquisition, and transmission, and a plurality of photovoltaic elements 207.
The radio wave 82 fed from the transceiver 204 is received by the antenna 205.
Radio waves received by the antenna 205 are transmitted to the circuit board 206 connected to the antenna 205.
The transmitted radio wave is converted into dc power in the circuit board 206. Then, the dc power is supplied to various devices 93 connected to the circuit substrate 206.
In this way, an example of the wireless power feeding unit 91 is configured by the antenna 205 and the circuit board 206.
As an example, the plurality of photovoltaic elements 207 are arranged in one-to-one correspondence with the display lamps 102 of the beacon 101. The light power generation element 207 generates power by lighting the display lamp 102, and supplies the generated power to the various devices 93 through the circuit board 206. Here, the various devices mean a communication device, an information processing device, a sensor device, or the like.
In this way, an example of the photovoltaic unit 92 is constituted by the photovoltaic element 207.
Further, the power generated by the lighting of each of the photovoltaic elements 207 of the photovoltaic unit 92 is recognized as lighting information of each of the display lamps 102, and the recognized lighting information is transmitted to the transceiver 204 via the circuit board 206 and the antenna 205 by the wireless information communication 81.
With this, in a state where all the display lamps 102 of the beacon tower 101 are not lit, in other words, in a state where the production facility 90 is not operating, by the power supply based on the radio wave 82, the various facilities 93 are driven, and information that the display lamps 102 are not lit is transmitted from the lighting detection sensor 201 to the transceiver 204. On the other hand, in a state where one or more of the display lamps 102 are lit, it is possible to drive the various devices 93 by combining the power supply based on the radio waves 82 and the power supply based on the photo-electric generation of the lighting light, and to transmit information on the lighting of the display lamps 102 from the lighting detection sensor 201 to the transceiver 204. The transceiver 204 transmits the lighting information to the data processing device 106, and the data processing device 106 determines the operation state of the production equipment 90 corresponding to the lighting information.
By continuously performing these processes, the operating state of the production facility 90 can be grasped in real time. Further, in this method, the power supply of the lighting detection sensor 201 is supplied from the power supply based on the radio wave 82 in the wireless power supply section 91 and the photovoltaic power supply based on the lighting light in the photovoltaic power generation section 92, and therefore, wiring for power supply and battery replacement are not required.
Next, the structure of the lighting detection sensor 201 will be described in detail with reference to fig. 2.
As described above, the lighting detection sensor 201 includes at least one antenna 205, at least one circuit substrate 206, and a plurality of photovoltaic elements 207.
The circuit board 206 includes at least the lighting detection control unit 99. The lighting detection control unit 99 includes, for example: a switching unit 301, a rectifying unit 302, a power supply control unit 303, a secondary battery 304, an information processing unit 305, and a communication unit 306. The 2-time battery 304 is not necessarily disposed on the circuit board, and may be electrically connected to a necessary portion of the lighting detection control unit 99.
The radio wave 82 transmitted from the transceiver 204 is received by the antenna 205, the switching unit 301 is switched to the rectifying unit 302 side, and converted into dc power by the rectifying unit 302. The power is charged into a 2-time battery 304 such as a capacitor or a storage battery connected to the power supply controller 303 by the power supply controller 303. Therefore, in this example, the antenna 205 and the rectifying portion 302 of the circuit board 206 constitute an example of the wireless power feeding portion 91.
At this time, when all the display lamps 102 are turned off and not turned on, since there is no power generation by the photovoltaic element 207, the dc power converted by the rectifier 302 generates lighting information that all the display lamps 102 are turned off by the information processor 305 at the time when the necessary power is stored in the battery 304 for 2 times, and the lighting information is switched to the communication unit 306 side by the switching unit 301 and then wirelessly transmitted by the communication unit 306 via the antenna 205 by the information processor 305. In this case, the lighting information is wirelessly communicated at a lower frequency (i.e., the 1 st frequency) than in the next case.
The case is a case where there is no power supply by only the radio wave 82 based on the power generation of the photovoltaic element 207. On the other hand, when the display lamp 102 of the beacon 101 is turned on, the photovoltaic element 207 generates power by lighting together with the power supply based on the radio wave 82, and the power is charged to the secondary battery 304 by the power supply control section 303. By the supply of electric power based on the radio waves 82 and the generation of electric power by the photovoltaic element 207, at the time when necessary electric power is stored in the battery 304 for 2 times, lighting information of each display lamp 102 based on information of the generated photovoltaic element 207 is generated by the information processing section 305, and the lighting information is switched to the communication section 306 side by the switching section 301 and then wirelessly transmitted via the antenna 205 by the communication section 306, using the stored electric power.
Therefore, in the state where the display lamp 102 is lit, the 2-time battery 304 is charged from both the power supply based on the radio wave 82 and the power supply based on the photo-electric generation, so that the necessary power can be stored by the 2-time battery 304 more quickly, and the wireless communication of the lighting information can be performed at the 2 nd frequency higher than the 1 st frequency in the previous case. In addition, in this photovoltaic power generation, power generation is performed not by indoor light but by bringing the lighting light of the beacon 101 into contact with the photovoltaic power generation, and therefore, power generation with high power can be performed stably.
Here, although the 1 st frequency and the 2 nd frequency are exemplified depending on the power transmission distance, the 2 nd frequency can be a frequency of once every several seconds with respect to a frequency in which the 1 st frequency is once every several minutes.
Here, although the rectifying unit 302 and the communication unit 306 are switched by the switching unit 301 for one antenna 205, two antennas 401 and 402 may be associated with the rectifying unit 302 and the communication unit 306, respectively, as shown in fig. 3. In the configuration of fig. 3, different frequencies can be allocated to power supply and information communication.
Next, a communication frequency based on the lighting state will be described with reference to fig. 4. Fig. 4 shows communication frequencies when the beacon 101 is composed of three display lamps 102 of blue, yellow, and red. When any one or more of the display lamps 102 of the beacon tower 101 is turned on, as described above, power can be supplied from both the power supply by the radio wave 82 and the photovoltaic power generation by the lighting light, and thus high-frequency communication at the 2 nd frequency can be performed. Here, the reason why high-frequency communication is required is that, as shown in fig. 4, there are cases where the lighting state of the beacon 101 is continuously lit and intermittent lighting, that is, flickering, and in the case of flickering (for example, in the case of the yellow indicator lamp 102 in fig. 4), by performing communication at intervals shorter than the flickering intervals, the state thereof can be grasped (see the frequency intervals of the "operating" interval of the communication frequency in fig. 4). On the other hand, in a state where all the beacon units 101 are not lit, the high-frequency communication is not necessary, and therefore, the operation can be sufficiently grasped even with the communication of a low frequency such as the 1 st frequency by only a weak power supply based on the radio wave 82 (refer to the frequency interval of the section of "stop" of the communication frequency in fig. 4).
In this way, by changing the communication frequency at the time of lighting and the time of extinguishing the display lamp 102 of the beacon 101, the operation can be grasped even in a wide range where the radio wave 82 is weak.
Next, a method of lighting the indicator lamp 102 of the identification beacon 101 will be described. As shown in fig. 1 and 2, a plurality of display lamps 102 are provided corresponding to one photovoltaic element 207. Here, when the display lamp 102 corresponding to the photovoltaic element 207 is individually turned on, the amount of power with which communication at a high frequency is possible is used as the reference amount of power. The distance between the light-generating element 207 and the display lamp 102 is set as follows: when the indicator lamp 102 corresponding to the photovoltaic element 207 is turned on alone, the amount of power generation equal to or larger than the reference power amount can be obtained, and the approach distance is obtained by which the amount of power generation in a state where the corresponding indicator lamp 102 is turned off and all of the other indicator lamps and the indoor light are turned on is sufficiently different from the reference power amount. The distance is, for example, as close as possible, more than 0mm and about 10mm or less.
Here, when any one of the indicator lamps 102 in the plurality of indicator lamps 102 is turned on, and when the generated power of the photovoltaic power generation element 207 corresponding to the indicator lamp 102 is equal to or greater than the reference power generation amount, the power supply control unit 303 recognizes that the indicator lamp 102 corresponding to the photovoltaic power generation element 207 is turned on. Conversely, when the generated power of the photovoltaic element 207 is smaller than the reference power generation amount, the power generation by the peripheral indicator lights or the room light is performed, and therefore the power supply control unit 303 can recognize that the indicator light 102 corresponding to the photovoltaic element 207 is not lit. Thus, the display lamps 102 are turned on to supply electric power capable of communication at a desired frequency, and the power supply control unit 303 recognizes the on state and off state of each display lamp 102 and wirelessly transmits the information to the transceiver 204 via the communication unit 306 and the antenna 205.
In the present embodiment, although the description is given using fig. 1, 2, and 4 for the case where there are 3 types of the indicator lamps 102, the number thereof is not limited, and the lighting and the turning-off of the indicator lamps 102 can be recognized by the power supply controller 303 in any case by using the above-described method.
In addition, although the display lamps 102 are generally distinguished by a plurality of colors such as red, blue, and yellow, in the above-described method, the reference power can be set for the lighting color of each display lamp 102 without depending on the color of the lighting light, and the reference power can be recognized by the power supply control unit 303 regardless of the type of the color.
In addition, although the power supply and the information communication between one transceiver 204 and one beacon 101 are described in the present embodiment, the power supply and the information communication may be performed for one transceiver 204 corresponding to a plurality of beacons 101 as shown in fig. 5. In this case, unique ID information is assigned to each of the plurality of signal towers 101, and the ID information is wirelessly communicated together with the lighting information, so that it is possible to identify which signal tower 101 the ID information is from. With this configuration, only one transceiver 204 needs to be arranged for a plurality of signal towers 101, and the configuration can be simplified. Further, power supply by wireless and power supply by photovoltaic power generation do not require power supply wiring and battery replacement, and furthermore, by changing the communication frequency between lighting and lighting of the beacon, a wide range of operation can be grasped.
In fig. 1, the antennas 202 and 205 are shown as flat plate-shaped antennas having directivity in a specific direction, but linear antennas having low directivity may be used depending on the installation state of the transceiver 204 and the signal tower 101.
According to the beacon lighting detection method and apparatus of the embodiment, since the beacon lighting detection is supplied from the supply of the electric power by the radio wave and the photo-generation by the lighting light, the operation information (in other words, the lighting information) from the beacon 101 of the production equipment 90 disposed in a wide range in the factory can be collected in real time at a necessary frequency without requiring the power supply wiring and the battery replacement.
In addition, any of the various embodiments or modifications can be combined as appropriate to achieve the effects of each. Furthermore, combinations of the embodiments with each other or with the embodiments, and combinations of features in different embodiments or with each other can also be performed.
