Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a service route of a communication base station which provides a tour route for a maintenance service and a trouble handling service for a plurality of communication base stations in which various devices are installed. The present invention relates to a providing system, a service traveling route providing method, and a navigation device used for traveling.

[0002]

In a mobile communication system, for example, a cellular phone system (cellular system), a small zone configuration having a radius of several kilometers is adopted in order to secure a wide service area. A wireless base station is installed for each. This radio base station is provided in a station building or one room of a building constructed on the roof or the ground of a building, and has communication equipment and auxiliary equipment (air conditioner or heat exchanger, ventilation fan, battery, power supply, control device, etc.). Equipment, security equipment, fire extinguisher, lighting, etc.).

The above-mentioned radio base stations scattered over a wide area are operated unmanned. Conventionally, service personnel (maintenance personnel) regularly (for example, once every six months) or radio base stations in each area according to empirical prospects. The bureaus patrolled together and maintained the above communication equipment and incidental equipment. However, in such a method, a radio base station that has just been constructed and a radio base station that has been used for a long time, or a radio base station with good environmental conditions and a radio base station with poor environmental conditions are circulated at the same interval. In other words, an inefficient and insufficient preventive maintenance cannot be performed such that a wireless base station that does not require maintenance becomes a target to be traversed, or conversely, the traversal is delayed and a failure (for example, a failure) occurs. .

[0004] In addition, the service technician needs to deal with sudden failures in addition to regular maintenance. In addition, the number of wireless base stations has been increasing due to the increase in subscribers to mobile phone services and the expansion of service areas in recent years. It has also spread to bad mountains and peaks. If the inefficient patrol as described above is continued in such a situation, there is a possibility that a wasteful time is spent on the patrol, sufficient preventive maintenance is not performed, and a bad situation in which the failure rate cannot be improved is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a communication base station which provides a traveling route for an optimum maintenance service and a trouble handling service which are efficiently and sufficiently preventively maintained. It is an object of the present invention to provide a service tour route providing system and a service tour route providing method, and a navigation device capable of improving convenience in the tour.

[0006]

According to the first aspect of the present invention, in each communication base station, the operating state detecting means and / or the environmental state detecting means operates the equipment installed in the communication base station. The communication means detects the status or the environmental status of the communication base station and transmits the detected status to the center as monitoring data.

[0007] The circulating route determination means of the center, based on the monitoring data received by the communication means and the maintenance data stored in the maintenance database, determines when a failure occurs in the equipment (for example, when a failure occurs or when a consumable part is replaced). Can be predicted with a certain degree of certainty. In particular,
In the case of detecting the operation state of the device, it is possible to predict the occurrence time of the device failure with higher certainty and to detect that the device has actually failed. The traveling route determining means calculates the service necessity for each communication base station based on the monitoring data and the maintenance data which enable such reliable prediction, and calculates each communication base station according to the calculated service necessity. Is determined.

[0008] Accordingly, services such as a communication base station in which a failure of a device which is an obstacle to maintaining a function as a communication base station in a normal state or a communication base station in which such a failure is likely to occur are required. It is possible to make a patrol from the highest level, and to provide an optimum maintenance service and a trouble handling service that are efficient and have a high preventive maintenance effect. As a result, a failure (particularly, an obstacle in maintaining a normal function as a communication base station) can be prevented beforehand, and the recovery of the occurred failure can be accelerated, so that the reliability of the communication system can be improved and It is possible to perform a tour with fewer maintenance staff compared to the conventional system.
In addition, the communication base station is also installed in a mountainous area or a mountaintop where road conditions are poor, and the work of maintenance personnel is reduced by eliminating unnecessary patrols.

According to the second aspect of the present invention, the circulating route determining means is capable of maintaining the function as the communication base station for each detected item whose status is detected and each storage item of the maintenance database. The importance indicating the importance of maintenance and troubleshooting is determined, and the service necessity is calculated based on the sum of the monitoring data and the maintenance data weighted by the importance. According to such a calculation method, a large number of monitoring data and maintenance data of a large number of communication base stations can be processed in a fixed procedure, and the calculation of the service necessity using a computer is an effective means. In addition, importance can be variably set for each communication base station according to the installation environment of the communication base station, season, time, weather, differences in equipment installed in the communication base station (for example, differences in manufacturers), and the like. It is possible to further enhance the accuracy of calculating the service necessity.

According to the third aspect, the traveling route determining means calculates the number of distances of the traveling route based on the position data stored in the map database, and based on the distance number and the service necessity. To determine the tour route,
For example, each communication base station can be traversed so that the number of distances of the traveling route that moves daily is minimized, and more efficient traversal becomes possible.

According to the fourth aspect of the present invention, the traveling route determination means calculates the time required for the traveling of the traveling route based on the position data and the traffic information stored in the map database. Since the patrol route is determined based on the service necessity, it is possible to minimize the delay of the patrol due to, for example, construction regulations or traffic congestion, thereby enabling more efficient patrol.

[0012] According to the means set forth in claim 5, the information of the tour route determined by the center is set as route information for the navigation device used for the tour of the communication base station. Although the communication base station is small and installed in various places, it is difficult for maintenance personnel to find it (it is difficult to reach). However, according to this means, maintenance personnel can display the screen of the navigation device or output audio. , The communication base station can be traversed along the trajectory determined by the center, and the convenience for maintenance personnel is enhanced.

According to the means described in claim 6, the equipment installed in the communication base station includes communication equipment, ancillary equipment such as an air conditioner, a ventilation fan, a storage battery, a power supply, a control equipment,
In the security device, etc., the auxiliary equipment (not to mention the communication equipment) operates normally by the optimum maintenance service and the failure handling service, so that the communication equipment can provide the communication service in an optimum state. The present invention can be applied to a communication base station including only a part of the above-described auxiliary facilities, or a communication base station including other auxiliary facilities and communication-related devices.

According to the means described in claim 7, the monitoring data relating to the environmental condition of the communication base station includes the inside air temperature, the outside air temperature, the inside air humidity, the presence or absence of smoke, and the like of the communication base station. An electronic device has a characteristic that its life decreases as the ambient temperature increases, and the life of the device can be predicted by detecting the inside air temperature. The detection of the outside air temperature and the inside air temperature indicates the load condition of the air conditioner, and the inside air humidity indicates an abnormal operation of the air conditioner. Further, by detecting the presence or absence of smoke, it becomes possible to detect the partial heating of the device or the occurrence of a fire.

According to the means described in claim 8, the maintenance data includes the last maintenance time, problems, and
MTBF and the like. By referring to the time elapsed since the previous maintenance time and the MTBF, it is possible to predict the failure occurrence time of the device with some certainty. In addition, by referring to the problem of the device, it is possible to estimate the susceptibility of the device to failure and the location of the failure, and it is possible to prepare maintenance parts in advance.

[0016] By the means described in claims 9 to 13, substantially the same operation and effects as those of the means described in claims 1 to 5 can be obtained. Further, according to the means described in claim 14, substantially the same operation and effect as the means described in claim 5 or 13 can be obtained.

[0017]

In the present service tour route providing system, a large number of wireless base stations 1 scattered over a wide area are centrally managed, and a tour route for a maintenance service and a trouble handling service of each of the base stations 1 is provided. In order to determine, a central monitoring station 10 corresponding to a center is installed. The central monitoring station 10 and each wireless base station 1 are connected by a communication line using an optical fiber.

The central monitoring station 10 is composed of a control device 11 mainly composed of a computer and a database 12, and the control device 11 communicates with the data communication device 9 of each wireless base station 1 as communication means.

Map data input device is C
This is an apparatus for inputting map data or the like recorded on a D-ROM, a DVD-ROM, or the like.

Next, the operation of this embodiment will be described. The control device 11 of the central monitoring station 10
The monitoring data transmitted from the data communication device 9 at regular intervals or as needed is received, and the monitoring data is stored in a storage device (not shown). Further, the database 12 stores maintenance data (corresponding to maintenance data) for each wireless base station 1 and map data (corresponding to position data) indicating the position of each wireless base station 1.

The control device 11 calculates the service necessity for each radio base station 1 based on the received monitoring data and the maintenance data stored in the database 12, and calculates the radio base station 1 having a high service necessity. As the tour priority (tour priority) becomes higher, a visit is made earlier (for example, at an earlier time during the day) to provide a service. Here, the service necessity means the urgency of the maintenance service and the trouble handling service necessary for the wireless base station 1 to provide the mobile phone in the cell in a normal state to the mobile phone service. Say.

Further, in order to realize more efficient patrol, the control device 11 sets the patrol priority based on the map data stored in the database 12 so that the moving distance required for patrol becomes as short as possible. Adjust to determine the tour route. For example, according to the above-mentioned service necessity, even when the radio base stations 1 extremely distant from each other form a traveling route on the same day, if the delay of the service for several days is not a problem, the It is possible to make a tour on the same day by adjusting within the day and combining the wireless base stations 1 that are close to each other.

Next, a specific method of calculating the service necessity will be described with reference to FIG. FIG.
(A) is an operating state and an environmental state (detection item, monitoring data) of each device detected, measured, diagnosed, etc. by each device or each sensor installed in the wireless base station 1, and an abnormality obtained by each detection item. It shows information (related factors), points of concern at the time of abnormality, and the importance of each detection item. Also,
FIG. 2B shows maintenance data (storage items) stored in the database 12, specific information of each storage item (related factors), points of concern at the time of abnormality, importance of each storage item, and the like. I have. The control device 11 stores the detected items and the stored items in numbers 1 to 21 and number 2 respectively.
Recognition is given with 2 to 24. The importance indicates the importance of maintenance and troubleshooting in maintaining the function of the wireless base station 1 normally. Hereinafter, each item will be described.

Environmental conditions (numbers 1 to 4) The temperature inside the station, the temperature outside the station, the humidity inside the station, and the presence or absence of smoke in the station are detected. The station has a sealed structure to prevent intrusion of dust and dirt into the station from outside, and the equipment installed in the station, especially the communication equipment 2, generates heat, so the station temperature rises. Easy to do. For this reason, the inside of the station is air-conditioned by the air conditioner 3, but if the temperature inside the station rises due to a failure of the air conditioner 3 or insufficient cooling capacity, each device shortens the life of the device or stops its operation. For this reason, the importance of the temperature in the office is set high.

The outside office temperature is detected mainly for monitoring the load condition of the air conditioner 3. The air conditioner 3 is in a higher load state as the temperature difference between the inside and outside of the station is larger. Further, the humidity in the office is controlled by the air conditioner 3 and is detected to monitor an operation abnormality of the air conditioner 3. If the humidity in the office building decreases, there is a risk that the equipment will be damaged by static electricity during the work of the service person. Furthermore, by detecting smoke,
It can monitor the overheating of combustible materials in the station building and the occurrence of fire. The importance of smoke detection is set high.

Operating state of air conditioner 3 (Nos. 5 to 9) The operating time, refrigerant pressure, operating sound, operation setting and air flow are detected. The operating time of the air conditioner 3 becomes longer as the temperature difference between the office temperature and the set temperature is larger. This operation time is measured by the measurement unit of the air conditioner 3, and is used, for example, to estimate the degree of wear of the movable unit. Also, by detecting the refrigerant pressure in the refrigeration cycle with a pressure sensor,
It is possible to detect abnormalities such as clogging of the refrigerant flow passage, compressor failure, and refrigerant leakage. When the refrigerant pressure decreases, the cooling capacity of the air conditioner 3 may decrease and the temperature inside the office may increase. Therefore, the importance of the refrigerant pressure is set to be relatively high.

By detecting abnormal sounds with microphones provided in the indoor unit 3a and the outdoor unit 3b, it is possible to monitor abnormalities of movable parts, for example, a compressor, a compressor motor, and a blower fan (motor). Further, by detecting the operation setting state of the air conditioner 3 by the setting detection unit of the air conditioner 3, it is possible to monitor, for example, an operation setting error between the cooling setting and the heating setting, a temperature setting error, and the like. If there is an error in the operation setting, the temperature inside the station becomes abnormal, so the importance of the operation setting is set to be high. Furthermore, indoor unit 3
By detecting the blown air flow rate using the air flow rate sensor at a, an abnormality of the internal fan can be monitored.

The operating state (numbers 10 and 11) of the ventilation fan 4 The ON / OFF state and the operating state are detected. As described above, the ventilation fan 4 is always stopped (OFF), and starts operating (ON) when the temperature in the office becomes equal to or higher than a predetermined temperature (for example, 45 ° C.). Therefore, ON / O
If the FF state is detected, it can be monitored that the temperature inside the station is abnormally high, and it can be seen that the air conditioner 3 is not operating normally. Further, by detecting the operating state, for example, a failure of the movable portion can be monitored. Ventilation fan 4 is air conditioner 3
This is a device for backing up, and the importance of the ON / OFF state and the operating state is set high.

The operating state of the battery 7 (numbers 12 to 1)
5) Temperature, voltage, liquid specific gravity and liquid level are detected. By detecting the temperature, the life of the battery 7 can be estimated, and by detecting the voltage, undercharging / overcharging of the battery 7 and failure of the charging / discharging device 6 can be detected. Further, by detecting the liquid specific gravity or the liquid level, the deterioration of the battery function can be monitored. Since the battery 7 is not normally used and the power outage of the communication base station 1 is rare, the importance of each detection item is set relatively low.

The operation state of the communication device 2 (numbers 16 and 1,
7) Temperature and diagnostic output are detected. By detecting the temperature of the communication device 2 itself, it is possible to monitor abnormal heat generation (that is, abnormal operation) of a power element or the like inside the device.
In addition, by obtaining the self-diagnosis result, the operation state of the communication device 2 can be monitored. The communication device 2
Because it is the most important device for providing mobile phone services,
The importance of each of the above detection items is set high.

The operating state of the power supply 5 (numbers 18, 1
9) Load condition and device life are detected. By detecting the load state with the current sensor, an abnormality in any device can be monitored. Further, the deterioration of the power supply device 5 itself can be monitored by detecting the supply voltage to the load with the voltage sensor.

Operating state of control device 8 (No. 20) By obtaining a diagnosis result by the self-diagnosis function of control device 8, the management state of each device installed in radio base station 1 can be monitored. If a failure occurs in the management function of the control device 8,
Since normal operation of the entire wireless base station 1 becomes difficult,
The importance of the diagnosis result is set high.

The security status of the radio base station 1 is monitored by detecting the unauthorized entry of a person into the station building by the operation state (number 21) of the security device. The importance of intrusion detection is set high because there is a possibility that devices may be destroyed or misused by unauthorized intrusion.

Maintenance (numbers 22 to 24) Previous maintenance time, problems, MT for each device
BF. The longer the elapsed time from the previous maintenance time, the more the need for maintenance increases. In this case, the MTBF of the device is referred to, and if the elapsed time exceeds the MTBF, the need for maintenance (for example, replacement of consumable parts) rapidly increases. In addition, information such as the problem of the device, for example, the presence or absence of a past failure, the location of the failure, and the notes submitted by the device manufacturer is referred to, and the frequency of occurrence of the failure of the device, the failure location, and the like can be estimated. The maintenance based on such maintenance data is set to be relatively low in importance because, for example, a delay of about several days is allowed.

The control device 11 gives each detection item (monitoring data) and each storage item (maintenance data) described above to a state level corresponding to the degree of abnormality. In the case of the station temperature Tin, for example, the following is performed.

If Tin <T1: state level 0 If T1 ≦ Tin <T2: state level 1 If T2 ≦ Tin <T3: state level 3 If T3 ≦ Tin: state level 5, where T1 to T3 are: Predetermined temperature that satisfies T1 <T2 <T3

Subsequently, as shown in the following equation (1), the control device 11 responds to each monitoring data (numbers 1 to 21).
The urgency A based on the monitoring data is obtained by multiplying the state level by the importance (see FIG. 2). Further, as shown in the following equation (2), each maintenance data (numbers 22 to 2) is obtained.
For 4), the urgency B based on the maintenance data is obtained by multiplying the state level by the importance (see FIG. 2) (corresponding to weighting). Then, as shown in the following equation (3), the control device 11 calculates the sum of the urgency A and the urgency B to obtain the service necessity.

Urgency A = status level of monitoring data × importance (1) Urgency B = status level of maintenance data × importance (2) Service necessity = Σ (urgency A) + Σ (urgency B …… (3)

As described above, the control device 11 determines a tour route based on the obtained service necessity and the map data, and then transfers the tour route information to the navigation device 14 mounted on the tour vehicle 13. I do. This transfer is
For example, it is executed by the Internet connection function and the file transfer function of the control device 11 and the navigation device body 16. The transferred tour route information is set as route information of the automatic guidance function of the navigation device 14. The service person can sequentially visit the wireless base station 1 according to the route determined by the central monitoring station 10 by the guidance or voice guidance displayed on the display 15.

As described above, according to this embodiment, various sensors for detecting the operating state of the equipment installed in the radio base station 1 and the environmental state of the radio base station 1 are installed, and these sensors are installed. And a state detected by self-diagnosis of the device itself or the like is transmitted to the central monitoring station 10 as monitoring data. Further, in the central monitoring station 10, each of the wireless base stations 1 based on the received monitoring data and the maintenance data stored in the database 12.
The required service level is calculated for each wireless base station 1 and the more the wireless base station 1 with the higher service required degree is determined, the faster the route is determined.

According to this configuration, it is possible to predict with high certainty the timing of occurrence of a malfunction of the device. Since the service necessity, which is a reference for determining the tour route, is the urgency of the maintenance service and the malfunction handling service based on the prediction, it is possible to make a tour from the radio base station 1 where a malfunction such as a breakdown is likely to occur. Thus, it is possible to provide an optimum service that is efficient and has a high preventive maintenance effect. As a result, it is possible to prevent the occurrence of a failure in the mobile phone service due to a device failure, and to shorten the recovery time even if a failure occurs, so that the reliability of each wireless base station 1 and, consequently, the overall mobile phone system can be reduced. Reliability is increased. In addition, unnecessary patrols can be reduced as much as possible, so that the labor of service technicians who patrols particularly in mountainous areas and peaks can be reduced.

The service necessity is calculated as a sum of weights indicating the importance of maintenance and troubleshooting for each item of the monitoring data and the maintenance data, and the status level of each data is weighted by the importance. Is done. Such a numerical calculation is suitable for the control device 11 configured by a computer, and is short even when the number of wireless base stations 1, the number of detected items of monitoring data, the number of stored items of maintenance data, and the like are large. The route can be determined in time. Thus, even if a sudden failure occurs, the traveling route can be corrected in a short time, and the corrected route can be transferred to the navigation device 14 mounted on the traveling vehicle 13. As a result, extremely efficient and highly adaptable services can be provided.

The importance of each wireless base station 1 depends on the installation environment of the wireless base station 1, the season, the time, the weather, the difference in the equipment installed in the wireless base station 1 (for example, the difference in the manufacturer), and the like. Can be variably set, and the accuracy of calculating the service necessity can be further improved.

Further, since the control device 11 determines the traveling route based on the map data so that the traveling distance required for the traveling is as short as possible, it is possible to set a more efficient traveling route. Although such adjustment based on the distance has been performed in the past, the conventional traveling route determination method relied on empirical prospects without a reliable traveling route determination guideline. Had been done. On the other hand, the traveling route determination method according to the present embodiment is intended to further reduce the moving distance on the premise of sufficient preventive maintenance based on a high degree of certainty of service necessity.

The obtained tour route information is transferred to the navigation device 14 mounted on the tour vehicle 13 and set as route information. Therefore, if the serviceman drives according to the automatic guidance function of the navigation device 14, the serviceman can easily and reliably reach the wireless base station 1 according to the determined traveling route, and the convenience at the time of traveling becomes higher.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows, for example. The communication base station is not limited to the wireless base station 1 in the mobile phone system, but may be a base station in another phone system or communication system. In the above embodiment, a sensor for detecting the operating state of the device installed in the wireless base station 1 and a sensor for detecting the environmental state of the wireless base station 1 are installed. The service necessity was calculated using both, but only a sensor for detecting one of the states was installed, and the service necessity based on the state (operating state or environmental state) detected by this sensor and the maintenance data was used. May be calculated.

The number and types (ie, types of monitoring data) of sensors to be installed and self-diagnosis functions, and the database 12
May be different from that of the above embodiment, and may be added or deleted as needed. For example, the operation state of the fire extinguisher, the lighting device, the cooling device of the communication device 2 and the like may be detected, and vibration may be detected instead of the operation sound of the air conditioner 3. Further, the equipment installed in the wireless base station 1 is not limited to the above embodiment, and may be provided with a heat exchanger instead of the air conditioner 3, for example.

Further, the central monitoring station 10 is provided with traffic information acquisition means for collecting traffic information such as construction information and traffic congestion information on the route, and determines the time required for the movement of the route based on the map data and the traffic information. It may be configured to calculate and determine a traveling route based on the required time and the service necessity. As a result, a delay in patrol due to construction regulations, traffic congestion, and the like can be minimized, and more efficient patrol can be performed.
