Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for checking a radio base station such as a mobile phone.

[0002]

2. Description of the Related Art Inspection of wireless base stations such as mobile phones has a short history, inspection items are unclear at the time of inspection, inspections are performed based on different judgment criteria for each inspector, and inspection reports are unified. There is no current situation.
For example, even if it is known that the deterioration of a certain inspection item progresses in stages, the degree of deterioration is not weighted as to what percentage of the deterioration from an objective point of view. Was.

[0003]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a system capable of maintaining and standardizing inspection items and objectively evaluating inspection results to enable efficient repair.

[0004]

In order to solve the above-mentioned problems, according to the present invention, a checklist is prepared in advance for the inspection items of the base station equipment, and the deterioration status is graded in advance for each of the inspection items of the checklist. Therefore, the deterioration can be quantified, and these data are made into a database, and a common deteriorated item among the inspection items is extracted from a database of many base stations to make a repair plan.

[0005] The above-mentioned inspection items include an image, and it is possible to grasp the state of deterioration in comparison with the image of the common inspection item in the database.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an example of hardware used in the system of the present invention. As shown in the figure, a computer 1 such as a personal computer is provided with a database 2 made up of a suitable storage medium, capable of inputting an image with a digital camera 3 and an image scanner 4, and provided with a suitable printer 5. Have been.

Next, the inspection process will be described with reference to FIG. First, in step 10, it is determined whether or not the base station to be checked is checked for the first time by this system. Note that this step is not necessary if necessary basic data is input in advance from completed books and the like for all base stations to be checked.

[0008] If there is no data on the base station in step 10, basic data from a completed book or the like is input in step 11. The items are as shown in the figure. Of course, other items may be input without being limited to these. On the other hand, if the basic data has already been entered,
In step 12, the basic data appearing on the screen of the computer 1 (FIG. 1) is checked for changes in the environment around the base station, leaks in the periodic inspection, and the like. Further, in step 13, the basic data is compared visually with the actual base station. As a result, if there is a difference or a blank, the process returns to step 11 to make correction and supplementary input.

When the database 2 (FIG. 1) is completed by the above process, an inspection operation by manpower is performed (step 14). This inspection is performed according to a checklist as shown in FIG. The survey items cover all base station equipment. As can be understood from the figure, the checklist in FIG. 3 describes, as much as possible, the specific situation of each component to be inspected with respect to the equipment to be inspected, for example, the antenna. It is represented by grade. The black circle in the figure is the deteriorated part, and the loosening of the antenna fixing bolt is recognized, indicating that the grade is “3”. Then, the total number of the deteriorated portions is also described.

The above inspection is not limited to visual inspection. For example, a wiping investigation of a coating film surface is performed, an image of a rusted portion is captured using a camera, and a plating thickness is measured using an appropriate measuring device (such as a film thickness gauge). These results are, of course, entered in a checklist. In the case of an image, the image is input to the computer 1 and a process described later is performed.

Next, it is determined whether or not there is a blank space in the check list (step 15). If there is a blank space, the process returns to step 14 again to check again. If there are no blanks in the checklist, the cause of the deterioration found in the inspection is investigated (step 1).
6). One way to find the cause of the degradation is to look for similar degradation. Therefore, in the system of the present invention,
The database 2 can be searched for similar deterioration. For example, when a search is made using the deterioration of the antenna feeder as a key, deterioration information of all past antenna feeders of the base station in the database 2 is displayed on the monitor of the computer 1. Then, the situation and countermeasures of similar deterioration can be investigated. If this doesn't help,
Consult a specialist (step 17) to determine the cause. Further, at step 18, it is confirmed whether there is any leakage of the photograph or the like. If there is no leakage, the inspection data is inputted to the database 2 at step 19. Of course, an image such as a photograph is also input directly or by using the scanner 4. At this time, the state of deterioration, degree of deterioration, etc. are written in the history, and the evaluation is performed based on the grades shown in FIG. 3 according to predetermined criteria. Is obtained.

Various maintenance and management can be efficiently performed by using the database 2 described above. The first is the repair of the deteriorated parts found in the inspection. not to mention,
Deterioration points and degrees of deterioration vary depending on the base station, and there are specialized construction contractors for each. 1000
It is extremely inefficient to repair individual base stations one after the other. Therefore, for example, for the coating work for repairing the deterioration of the coating film, the deterioration of the coating film is selected from the database 2 in which the checklist of the inspection work is inputted, and the base stations are arranged in the order of the evaluation points according to the grade and listed. When a table or a graph is prepared and the painter performs the work in accordance therewith, the efficiency is improved and at the same time it is possible to respond to urgent demands. In this way, it is possible to quickly provide data for a professional contractor to efficiently perform repair work according to the type of work performed due to the deteriorated location. In addition, since images such as photographs have been input, it is possible to judge the similarity compared to the previous time and the deterioration status of other base stations, and if the repair items at that time were viewed, the cause and countermeasures could be known. , Prompt repair is possible. After the completion of the construction, the information is written in the database 2 in the history related to the location.

[0013]

According to the present invention, as described above, the inspection is performed according to the checklist, and the state of deterioration can be quantified by dividing it into grades. By making these data into a database, it is easy to find the cause of repairs and the like, and the entire repair plan can be easily planned, so that efficient repairs can be made and costs can be reduced. .
