Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a streetlight monitoring system, and more particularly to a streetlight monitoring system suitable for performing maintenance and management of a large number of streetlights installed in a large area.
[0002]
[Prior art]
When a streetlight installed on a street is cut off, the pedestrian or nearby residents who have found it will contact the management organization, or if a maintenance inspector is assigned, the maintenance inspector will discover it on a regular patrol. And contact the governing body. Upon receiving this notification, the management agency will replace the broken streetlight.
[0003]
[Problems to be solved by the invention]
When a pedestrian or local residents discover that a street lamp has run out, the management organization is not always notified of the fact that the street light has run out, and it may be significantly delayed for the management organization to know about the street lamp running out. Passengers, especially those who do not know where to contact, are often not willing to inform themselves. In this case, the communication is delayed at least until discovered by another person. As a result, if the detection of street light burnout by the management organization is greatly delayed, the risk of a traffic accident or another accident increases, which is not preferable.
[0004]
On the other hand, when a street light is detected by a maintenance staffer, the shorter the inspection cycle, the shorter the delay in detecting a street light cutoff. Therefore, it is not easy to secure the personnel. In addition, when the inspection work is performed only by visual inspection, it is limited to nighttime when the streetlight is turned on, and it requires a great deal of labor in a depopulated area or a mountainous area. It is also possible to perform the inspection by turning on the light in the daytime, but in that case, the inspection work takes time and the burden on the inspector increases.
[0005]
An object of the present invention is to provide a streetlight monitoring system that does not require a maintenance work by a maintenance and inspection person, and enables a management organization to automatically and quickly grasp the outage of a streetlight without communication by a pedestrian or the like. .

[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described. FIG. 1 is a block diagram showing a configuration example of a streetlight monitoring system according to the present invention. Modules 3, 3,... Provided for each streetlight installation location and a management institution device 1 are connected via a network system 2. The network system 2 only needs to be a system that can transmit information including the detection result of the outage of the streetlight from each module to the management institution apparatus 1, and may be any system that can be easily used depending on the location of the streetlight. For example, a public telephone network, a mobile telephone network, a cable broadcasting network, a power line carrier network, a wireless communication network, and the like, and not all modules need to use the same type of network.
[0010]
Each of the modules 3, 3,... Is provided with a detection unit 31, a control processing unit 32, a data memory 33, and a communication unit 34 for detecting a burnt out street lamp. The communication unit 34 has a communication function corresponding to the network system used by the module. As a method of detecting the turning off of the streetlight by the detecting unit 31, for example, a current value flowing when the power of the streetlight is turned on is detected, or a photo sensor is provided to detect the brightness of the streetlight. In the case of current detection, the detection operation can be performed by temporarily turning on the power supply for the test not only at night but also during the daytime. In the case of a photo sensor, the detection is not suitable for daytime when the surroundings are bright, and the detection operation is mainly performed at night.
[0011]
The control processing unit 32 captures the detection result by the detection unit 31, generates inspection data including the result, stores the inspection data in the data memory 33, and transmits the inspection data to the management institution device via the communication unit 34. Control. First, the detection result of the detection unit 31 is taken in according to the inspection mode. In the inspection mode, when a streetlight burnout is constantly monitored at night or the like and the information is taken in at the timing when the streetlight burnout is detected, the capturing operation is performed using information indicating the detection of the streetlight burnout from the detection unit 31 as a trigger. When the detection operation is performed periodically in the inspection mode, a command is periodically output from the control processing unit 32 to the detection unit 31 to perform the detection operation, and the result is captured. In any of the inspection modes, when the inspection is not performed in the daytime or the like, the capturing operation in that time period is also stopped.
[0012]
The inspection data generated by the control processing unit 32 needs to be data that allows at least the management institution device 1 to identify which streetlight the data belongs to. FIG. 2 shows an example of the format of the inspection data, in which an ID indicating the type of the corresponding streetlight, a type indicating the type of the streetlight such as a fluorescent lamp or an ordinary light bulb, its type, wattage, and color are shown. It consists of the information and the time when the streetlight burnout was detected. Since the ID and type information are unique values for each module, they are set in the control processing unit in advance. For the streetlight cut-off time, a clock function is provided in the module, and the time is referred to. In the example of the format shown in FIG. 2, it is assumed that the detection time of the street lamp is detected. However, when the street lamp is not detected, this time is indicated as a specific value (such as “0”). Alternatively, when there is no running out of the streetlight, no frame may be created and nothing may be transmitted. The created data frame is stored in the data memory 33.
[0013]
The control processing unit 32 controls the transmission of the test data to the management institution device 1 such that the test data stored in the data memory 33 is transmitted by the communication unit 34 at the timing of the occurrence of a streetlight burnout or at a periodic timing. It is preferable that the transmission control is terminated by receiving a reply signal indicating that the inspection data has been normally received by the management institution apparatus 1, and to perform retransmission control when normal reception is not confirmed. By doing so, even if the transmission fails due to the status of the network system 2 or the traffic state of the management institution apparatus 1, the inspection data can be transmitted more reliably by retransmission.
[0014]
The management institution 1 includes a control processing unit 11, an operation display unit 12, a database 13, and a communication unit 14. The communication unit 14 has a function of operating with any of a plurality of network systems used by the modules 3, 3,.
[0015]
The control processing unit 11 performs processing for receiving test data from each module and processing for maintenance management. FIG. 3 is an example of a flowchart showing the operation of the control processing unit 32. First, when inspection data is received by the communication unit 14 (YES in step 301), the reception table in which the reception inspection data is provided in the database 13 is provided. (Step 302). In this reception table, for example, each item of the inspection data as shown in FIG. 2 is directly associated and stored together with the reception time. If the received inspection data includes information on the outage of the streetlight, the information is displayed on the operation display unit 12 to notify the operator of the outage of the streetlight (step 303). In this display, if the name of the installation place is displayed together with the ID of the streetlight, and the type information is also displayed by the name of the streetlight, etc., the operator can promptly notify the worker of an instruction to replace the streetlight. FIG. 4 shows an example of this display, where installation locations A and B are street names, street numbers, and the like that are easily understood by the operator. Further, when the outage of the streetlight is received, the fact is also written in the maintenance data described later (step 304).
[0016]
When the above reception processing has been completed or when the inspection data has not been received (NO in step 301), it is checked whether or not an input indicating that the streetlight has been replaced (or newly installed) has been made (step 305). The maintenance data to be updated is updated (step 306). The streetlight maintenance data is a table of the date and time of new or replacement of each streetlight, the date and time of occurrence of a streetlight burnout, and the like, and is, for example, a table as shown in FIG. That is, a time series of an event in which “EX” is added to a streetlight type corresponding to a module indicated by an ID and a date of new or replacement and “DN” is added to a date of expiration of the streetlight is shown. The date when the street lamp was turned off was recorded in step 304. For example, the street light type of the module indicated by ID = L1 in FIG. 5 is α (fluorescent light type 30 or the like) and the exchange (EX) is May 1, 2001, which expires on December 3, 2001, and the next day, December. It shows that it was exchanged on the 4th. As for the time series of this event, all events after the new establishment may be recorded, or events earlier than the appropriate number of events or time width from the present time may be discarded. If the maintenance data can be displayed at any time by operating the operation display unit 12, the maintenance status of each streetlight can be known in a time series.
[0017]
When the maintenance data has been updated or there has been no streetlight replacement input (NO in step 305), it is next checked whether or not the type data has been updated (step 307). As shown in FIG. 6, the type data referred to here is data in which the life time of each streetlight, its average value, the minimum value, and the like are recorded for each type of streetlight. Here, the individual life (life of each streetlight) can be obtained from the time from replacement (or new installation) to the next running out of the streetlight in the maintenance data of FIG. Further, the length of the life time may be the number of days elapsed from the date of replacement to the end of the street lamp, or the actual lighting time may be sent from the module and calculated as the total lighting time. When the type data change time comes, the maintenance table shown in FIG. 5 is checked, and when a new street light is out, the individual life as described above is obtained and stored in the type data table as shown in FIG. The value and the minimum value are updated (step 308). If the type data can be referred to on the operation display unit 12 at any time, the actual life of various street lamps can be known, so that a great effect can be obtained in predicting the inspection time and planning replacement supplies.
[0018]
The cycle of the type data update time may be an interval of once a month, and may be started manually instead of being incorporated into a routine as shown in FIG.
[0019]
Next, another embodiment of the present invention will be described. FIG. 7 is a block diagram illustrating another configuration example of the streetlight monitoring system of the present invention. A module 8 or a host 7 is provided for each streetlight installation location, and a single host 7 includes a plurality of modules 8, 8. Connected via a wireless line. The unit composed of this one host and the modules 8, 8, ... wirelessly connected to it is hereinafter referred to as a sector. Each of the sectors 6, 6,... Is connected to the management institution device 4 via the network system 5. Here, the network system 5 only needs to be usable as in the case of FIG. 1, or may be a different network for each sector.
[0020]
In the configuration of FIG. 7, the operation of the detection method of the streetlight burnout detection unit 83 in each of the modules 8, 8,. This is performed in the same manner as in the case of 1. However, the test data stored in the data memory 84 is not directly transmitted to the management institution device as shown in FIG. 1, but is transmitted to the host 7 in the own sector via the wireless communication unit 81 once. The transmission format of the inspection data is the same as that of FIG.
[0021]
When the host 7 receives the inspection data from the modules 8, 8,... Via the wireless communication unit 73, the control processing unit 72 stores the inspection data in the data memory 75 and fetches the detection result by the detection unit 74 of the host itself. Inspection data is generated and also stored in the data memory 75. The detection method by the detection unit 74 and the format of the inspection data to be generated are the same as those in FIGS. As a result, the data memory 75 of the host 7 stores the test data obtained by all the modules in the sector 6 and the host, so that the control processing unit 72 sends these data through the communication unit 71 and the network system 5. Are sent to the management institution device 4 periodically or in response to a command from the management institution device. FIG. 8 shows an example of the data format at this time, which is composed of sector information indicating from which sector the information is, and the inspection data of each of the streetlights (modules) 1, 2,. The host 7 may have only the function of collecting the test data of the modules in the sector and communicating with the management institution without having the test unit.
[0022]
The operation of the management institution device 4 is the same as that of FIG. 1, and the control processing unit 42 performs a process of receiving test data from each sector via the network system 5 and the communication unit 43, and a process for maintenance management. The operation flow is the same as that of FIG. That is, only the point that the inspection data for each sector is collectively processed in the reception processing from reception of the inspection data to storage in the database 44 is different from the case of FIG. The maintenance management such as generation and update of maintenance data and type data is exactly the same.
[0023]
According to the configuration of FIG. 7 described above, several modules are grouped into a sector, and communication with the management institution device is performed in a unit of a sector. As a result, it is possible to save the communication means as a whole and to reduce the cost. it can. That is, the modules provided in the same sector are close to each other in distance, and can communicate with a host in the same sector by a simple wireless system, for example, a transmission system capable of communicating by Bluetooth or the like. The host is provided with a communication unit capable of communicating with the management institution device via the network system, and the communication unit is used to collectively send all the inspection data taken in the same sector to the management institution device. This eliminates the need to provide a communication unit having an expensive and complicated function for each module, so that the cost of the entire system is greatly reduced.
[0024]
【The invention's effect】
Advantageous Effects of Invention According to the present invention, it is possible to quickly and reliably grasp the disconnection of a large number of scattered street lamps, and to appropriately perform replacement work.
