Of these, the terminal device performs wireless communication with the relay wireless communication device.

In such a wireless communication system, a plurality of relay wireless communication devices are provided, and the relay wireless communication device to which the terminal device is connected is switched according to the condition of the radio wave emitted from each relay wireless communication device to obtain a predetermined communication area. There is a technique for enabling communication with an information processing device via any relay wireless communication device at an arbitrary position within (for example, Patent Documents 1 and 2). In this technology, a site survey is conducted to investigate the condition of radio waves emitted from a plurality of relay wireless communication devices before the operation of the wireless communication system is started, and at least one relay wireless communication device is used for each position in the communication area. The position and number of relay wireless communication devices are adjusted so that the radio waves can reach.

Store and manage the information provided. A plurality of servers 10 may be provided. The communication network N can be, for example, the Internet, but may be a network such as a LAN or WAN (Wide Area Network).

In the information acquisition management system 1, a bar code (identification mark) attached to a product or the like as an article to be identified is read by the handy terminal 30. Then, the read barcode and the information related to the product identified by the barcode (hereinafter, also referred to as barcode information) are transmitted from the handy terminal 30 to the server 10 via wireless communication with the access point 20. It is sent and managed. This barcode information corresponds to "identification mark information". The barcode information includes at least content that can identify the read barcode. Further, the barcode information includes information obtained by decoding the barcode and information previously associated with the information (for example, product information previously associated with the product code obtained by decoding the barcode). ), And information on the quantity of goods counted according to the reading of the barcode may be included. The barcode may be a one-dimensional barcode or a two-dimensional barcode.

The information acquisition management system 1 can be used, for example, for inventory of products in the retail business, picking of products in a warehouse in the distribution and sales business, and the like. In these cases, the access point 20 is installed in a facility such as a store in the retail business or a warehouse in the distribution and sales business, and the handy terminal 30 is used in the facility. On the other hand, the server 10 is not particularly limited in its installation position as long as it can send and receive information to and from the access point 20 via the communication network N, and may be installed in the above facility or remotely.

The reference radio wave distribution data 143 is pre-registered reference information that is referred to when detecting an abnormality in a radio wave, which will be described later. Here, the predetermined distribution of radio waves is the distribution of radio waves when the site survey in the communication area 2 is last performed.

FIG. 5 is a diagram illustrating a site survey of the communication area 2.
The site survey refers to investigating the status such as the strength of radio waves emitted from each access point 20 at each position in the communication area 2. As a result of the site survey, if there is an area where it is difficult to perform wireless communication with all the access points 20, the site survey is performed again after adjusting the position and number of the access points 20.

Further, the reference radio wave map 1432 is generated and stored in the storage unit 14 based on the result of the site survey and the position correspondence data 142.

FIG. 7 is a diagram showing a content example of the reference radio wave map 1432 generated based on the result of the site survey of FIG.
The reference radio wave map 1432 is data showing the distribution of radio wave intensities from each access point 20 in the communication area 2. Specifically, the reference radio wave map 1432 divides the communication area 2 into a plurality of predetermined unit areas, and associates each unit area with a representative value of the radio wave intensity in the unit area. The size of the unit area can be arbitrarily determined, and the shapes may be different from each other. When a plurality of radio wave intensities are specified in the unit region, the representative value of the radio wave intensity may be an average value, a median value, a maximum value, a minimum value, or the like of the plurality of radio wave intensities. Further, when one radio wave intensity is specified in each unit area, the radio wave intensity may be used as a representative value.

The reference radio wave map 1432 includes the first reference radio wave map 1432a (FIG. 7 (a)) showing the distribution of the radio wave intensity from the first access point 20a and the distribution of the radio wave intensity from the second access point 20b. A second reference radio wave map 1432b (FIG. 7 (b)) showing the above is included.

In the first reference radio wave map 1432a shown in FIG. 7A, the communication area 2 is divided into regions R1a to R1d adjacent to each other in the X direction according to the strength of the radio wave from the first access point 20a. .. Each of the regions R1a to R1d may be the above-mentioned unit region, or may include a plurality of unit regions. Of these, the radio field intensity in the region R1a is the highest, and the radio wave strength in the region R1c is the lowest. Specifically, the region R1a is a region having a radio field intensity of −50 dBm or more, the region R1b is a region having a radio field intensity of −70 dBm or more and less than -50 dBm, and the region R1c is a region having a radio field intensity of −90 dBm or more and −70 dBm. The region is less than −90 dBm, and the region R1d is a region having a radio field intensity of less than −90 dBm. In FIG. 7A, the higher the radio field intensity, the higher the density of dots. The area R1a includes the position P1 of the first access point 20a, the area R1b contains the position PB1 of the barcode B1, and the area R1c contains the positions PB2 and PB3 of the barcodes B2 and B3. include.

Similarly, in the second reference radio wave map 1432b shown in FIG. 7B, the communication area 2 is divided into regions R2a to R2d adjacent to each other in the X direction according to the strength of the radio wave from the second access point 20b. Has been done. Each of the regions R2a to R2d may be the above-mentioned unit region, or may include a plurality of unit regions. Of these, the radio field intensity in the region R2a is the highest, and the radio wave strength in the region R2d is the lowest. Specifically, the region R2a is a region having a radio field intensity of −50 dBm or more, the region R2b is a region having a radio field intensity of −70 dBm or more and less than -50 dBm, and the region R2c is a region having a radio field intensity of −90 dBm or more and −70 dBm. The region is less than −90 dBm, and the region R2d is a region having a radio field intensity of less than −90 dBm. The area R2a includes the position P2 of the second access point 20b, the area R2c includes the positions PB2 and PB3 of the barcodes B2 and B3, and the area R2d contains the position PB1 of the barcode B1. include.

The reference radio wave map 1432 may be image data showing the distribution of radio wave intensities as shown in FIG. 7, or may be table data in which the radio wave intensities are associated with each unit region. As the table data, for example, the reference radio wave intensity data 1431 of FIG. 6 may be expanded so as to include a position (unit area) in which the barcode is not arranged.

As described above, the reference radio wave distribution data 143 shows the radio wave intensity distribution in the last site survey. On the other hand, the detected radio wave distribution data 144 shows the intensity distribution of the latest radio wave detected after the site survey. As will be described later, the CPU 11 of the server 10 can specify the intensity of the radio wave emitted from the access point 20 at the position of the handy terminal 30 based on the data received from the handy terminal 30. The detected radio wave distribution data 144 is data that reflects the latest identified radio wave intensity.
The detected radio wave intensity data 1441 and the detected radio wave map 1442 included in the detected radio wave distribution data 144 are data in the same format as the reference radio wave intensity data 1431 and the reference radio wave map 1432, respectively. The specific contents of the detected radio wave distribution data 144 will be described later.

The operation unit 15 shown in FIG. 3 has a key input unit such as a keyboard and a pointing device such as a mouse, receives key operation input and position operation input from a user (operator), and transmits the operation information to the CPU 11. Output.

The display unit 16 is composed of a liquid crystal display, an organic EL (Electro Luminescence) display, or the like, and displays the results and status of various processes.

The communication unit 17 is composed of a LAN board, a LAN card, or the like, and under the control of the CPU 11, data is transmitted / received to / from the handy terminal 30 via the communication network N and the access point 20.

Next, the configuration of the handy terminal 30 will be described.
FIG. 8 is a block diagram showing a main functional configuration of the handy terminal 30.
The handy terminal 30 includes a CPU 31, a RAM 32, a ROM 33, a storage unit 34, an operation unit 35, a display unit 36, a wireless communication unit 37 (communication means, radio wave detection means), and a barcode scanner 38 (reading means). ) And a bus 39 and the like. Each part of the handy terminal 30 is connected via a bus 39.

The CPU 31 is a processor that controls each unit of the handy terminal 30 by performing various processes according to the program 341 stored in the storage unit 34. The CPU 31 functions as a communication control means and a connection target selection means by executing the program 341 and performing various processes.

The RAM 32 provides the CPU 31 with a working memory space and stores temporary data. The RAM 32 may include a non-volatile memory.

The ROM 33 is a non-volatile storage unit capable of reading information, and stores various setting data and the like.

The storage unit 34 includes a storage device such as an HDD, an SSD, and a flash memory capable of writing and reading data, and stores the program 341 and various data. The data stored in the storage unit 34 includes the product inventory data 342 used in the inventory operation described later, and the radio wave detection result data 343 including the information of the radio wave detection result by the wireless communication unit 37.

The operation unit 35 includes a trigger key for executing bar code scanning, a cursor key, input keys for numbers and characters, function keys, and the like. The operation unit 35 converts the input operation for these keys by the user into an operation signal and outputs it to the CPU 31. The operation unit 35 may receive an input operation from the user by a touch panel arranged so as to be superimposed on the screen of the display unit 36.

The display unit 36 is composed of a liquid crystal display, an organic EL display, or the like, and displays the results and status of various processes of the handy terminal 30.

The wireless communication unit 37 is a communication module having an antenna, a modulation / demodulation circuit, a signal processing circuit, and the like, and performs communication control corresponding to a communication standard related to wireless communication by wireless LAN. Under the control of the CPU 31, the wireless communication unit 37 performs wireless communication with one access point 20 set as a communication connection target in advance, and performs data with the server 10 via the access point 20 and the communication network N. To send and receive. The wireless communication unit 37 also functions as a radio wave detecting means for separately detecting the intensity of radio waves emitted from each access point 20.

The switching (roaming) of the access point 20 to be connected to the communication is controlled by the CPU 31, and the BSSID (usually the MAC (Media Access Control) address of the access point 20) and the channel used are rewritten. It is done by being done.

The bar code scanner 38 reads the bar code generated according to a predetermined rule, decodes the obtained signal, and outputs the signal to the CPU 31. At least a part of the signal decoding process may be performed by the CPU 31.
The bar code scanner 38 of the present embodiment is a laser scanner, receives the reflected light of the bar code of the light emitted from the laser diode, and converts the detected intensity distribution of the reflected light into a digital signal. The barcode scanner 38 is not limited to a laser scanner, and an imaging device having an optical system and an imaging element may be used as the barcode scanner 38, for example. In this case, the information can be acquired by decoding the image pickup data of the barcode.

Next, the operation related to the acquisition and management of information in the information acquisition management system 1 will be described. In the present embodiment, the operation of the handy terminal 30 and the operation of the server 10 will be described by taking as an example the case where the information acquisition management system 1 is used for inventory of products in a store.

When inventory is performed using the information acquisition management system 1, the following operations are performed in the handy terminal 30.
First, the bar code attached to the product in the communication area 2 is read by the bar code scanner 38 in response to the user's input operation to the operation unit 35. The barcode information obtained from the barcode reading result is transmitted to the server 10 by the wireless communication unit 37 via the access point 20.

Further, when the barcode is read by the barcode scanner 38, the intensity of the radio wave emitted from each access point 20 is detected by the wireless communication unit 37. Here, it is desirable to detect the radio wave intensity when the bar code is being read by the bar code scanner 38, but the detection of the radio wave intensity may be performed before or after reading the bar code. The radio wave information indicating the strength of the detected radio wave is stored in the storage unit 34 as the radio wave detection result data 343, and is transmitted to the server 10 together with the barcode information. The detection of the radio wave and the transmission of the radio wave information are performed automatically, that is, without being instructed by the user.

On the other hand, when the server 10 receives the barcode information and the radio wave information, the server 10 performs the following operations.
First, the received barcode information is stored in the storage unit 14 and managed as inventory information.

Further, the reading position, which is the position when the handy terminal 30 reads the barcode, is specified based on the barcode indicated by the received barcode information and the position correspondence data 142. Specifically, the position associated with the barcode read in the position-corresponding data 142 is specified as the reading position. For example, when the barcode indicated by the received barcode information is the barcode B1, the position PB1 associated with the barcode B1 in the position correspondence data 142 of FIG. 4 is specified as the reading position.

Next, in the reference radio wave distribution data 143 as the reference information registered in advance, the access is based on the comparison result between the radio wave intensity corresponding to the specified reading position and the radio wave intensity indicated by the received radio wave information. An abnormality in the radio wave emitted from point 20 is detected.
If there is no abnormality in the distribution of the radio waves, the received radio wave strength matches the radio wave strength corresponding to the reading position in the reference radio wave distribution data 143 (hereinafter, referred to as “reference radio wave strength”). For example, when the barcode B1 is read and the position PB1 is specified as the reading position, the radio wave intensity indicated by the received radio wave information is the reference radio wave strength data of FIG. 6 if there is no abnormality in the radio wave distribution. At 1431, it coincides with the reference radio field intensity (-40 dBm, -100 dBm) corresponding to the position PB1.

However, after the site survey, if the arrangement of the structure that blocks the radio wave is changed in the communication area 2 or if some access points 20 break down, the received radio wave strength differs from the reference radio wave strength (usually small). Will be) in some cases. Therefore, when the difference between the received radio wave strength and the reference radio wave strength is equal to or greater than a predetermined reference difference, an abnormality in the radio wave emitted from the access point 20 is detected. The reference difference may be a value common to all the unit regions, or may be a size corresponding to the reference radio field intensity in the unit area (for example, 20% of the reference radio wave strength, etc.).

When an abnormality in the radio wave is detected, a warning screen for notifying the abnormality is displayed on the display unit 16. The warning screen is arbitrary as long as it contains at least the content notifying that an abnormality has occurred in the radio wave. The display operation of the warning screen by the display unit 16 is one aspect of the “notification operation”.

When an abnormality in the radio wave is detected, the detected radio wave distribution data 144 is generated based on the received radio wave intensity and stored in the storage unit 14. That is, the detection radio wave intensity data 1441 with the content modified from the reference radio wave intensity data 1431 based on the received radio wave intensity is generated, and the detection radio wave map 1442 with the content modified with the reference radio wave map 1432 based on the received radio wave intensity is generated. Then, it is stored in the storage unit 14 as the detected radio wave distribution data 144. If the detected radio wave distribution data 144 has already been generated, the content of the detected radio wave distribution data 144 is modified and updated.

Next, the operations of the handy terminal 30 and the server 10 described above will be described with reference to specific examples.
Here, as shown in FIG. 9, an example is taken in the case where a shield M that shields radio waves is placed between the position P2 of the second access point 20b and the position PB2 of the barcode B2 after the site survey. I will explain it by listing it. Since the shield M is placed, the strength of the radio wave emitted from the second access point 20b is weakened in the region opposite to the position P2 side with respect to the shield M. On the other hand, the intensity of the radio wave emitted from the first access point 20a is weak enough to be ignored at the position of the shield M, and is hardly affected by the shield M.

Under the situation shown in FIG. 9, the barcode B2 was read by the handy terminal 30 as shown in the “reading result 1” of FIG. 10, and then the barcode B3 was read as shown in the “reading result 2”. The operation of the case will be described.

The radio field intensity detected at the time of reading the barcode B2 of "reading result 1" is (-80 dBm, -100 dBm). The radio wave information indicating the radio wave strength is transmitted to the server 10 together with the bar code information related to the reading result of the bar code B2. In the server 10, the position PB2 of the barcode B2 is specified as the reading position of the handy terminal 30 based on the received barcode information and the position correspondence data 142.

The radio field intensity (-80 dBm, -100 dBm) detected when reading the barcode B2 is compared with the reference radio field strength (-80 dBm, -80 dBm) corresponding to the position PB2 in the reference radio field strength data 1431 of FIG. The radio field strength of the second access point 20b is reduced by 20 dBm. As a result, it is determined that there is an abnormality in the distribution of the radio waves emitted from the second access point 20b, and the abnormality is detected. When an abnormality in the radio wave is detected, the detected radio wave intensity data 1441 and the detected radio wave map 1442 are generated.

FIG. 11 is a diagram showing a content example of the detected radio wave intensity data 1441.
As shown in FIG. 11, the detected radio field strength data 1441 determines the radio field strength corresponding to the position PB2 of the reference radio field strength data 1431 in FIG. 6 as the radio field strength (-80 dBm, -100 dBm) detected in the “reading result 1”. Corresponds to the modified version.

Further, FIG. 12 is a diagram showing an example of the contents of the detection radio wave map 1442.
FIG. 12 shows the second detected radio wave map 1442b showing the distribution of the radio wave intensity of the second access point 20b in the detected radio wave map 1442. According to the radio wave information received in the "reading result 1", it is estimated that the shield M is located at any position between the position P2 and the position PB2. However, at this stage, it is not possible to specify the range in which the shield M exists in the communication area 2. That is, the entire area between the position P2 and the position PB2 in the X direction in the communication area 2 is an estimated region Rx in which the shield M may exist. Therefore, at this stage, with respect to the second reference radio wave map 1432b shown in FIG. 7B, a second detected radio wave map 1442b having the content of downwardly modifying the radio wave intensity in the estimated region Rx is generated. Specifically, the area R2a on the + X direction side of the second access point 20b in the communication area 2 is defined as the area R2a, and the entire area 2 on the -X direction side from the second access point 20b has a radio field strength of -90 dBm. It is defined as a region R2d indicating that it is less than.

After that, it is assumed that the barcode B3 of the "reading result 2" is read, and the radio field intensity detected at the time of the reading is (-80 dBm, -80 dBm) as shown in FIG. The radio wave information indicating the radio wave strength is transmitted to the server 10 together with the bar code information related to the reading result of the bar code B3. In the server 10, the position PB3 of the barcode B3 is specified as the reading position of the handy terminal 30 based on the received barcode information and the position correspondence data 142.

The radio field strength (-80 dBm, -80 dBm) detected when the barcode B3 is read is the reference radio field strength (-80 dBm, -80 dBm) corresponding to the position PB3 of the bar code B3 in the reference radio field strength data 1431 of FIG. Match. Therefore, the detected radio field intensity data 1441 shown in FIG. 11 is not modified.

On the other hand, from the detection result of this radio wave intensity, it is determined that the radio wave is normally distributed between the position P2 and the position PB3. That is, it can be estimated that there is no shield M between the position P2 and the position PB3. Based on this, the second detected radio wave map 1442b of the detected radio wave map 1442 is modified.

FIG. 13 is a diagram showing a content example of the modified detection radio wave map 1442.
As shown in FIG. 13, based on the above estimation result, the radio wave distribution in the half region on the −Y direction side with respect to the Y direction, including the region between the position P2 and the position PB3, is a normal distribution, that is, FIG. The radio wave distribution is modified to be the same as that of the second reference radio wave map 1432b in 7 (b). On the other hand, the radio wave distribution in the half region on the + Y direction side with respect to the Y direction is maintained as shown in FIG. As a result, the estimated region Rx in which the shield M may exist is narrowed down to a half region on the + Y direction side in the Y direction among the regions between the position P2 and the position PB2 in the X direction.

In this way, each time the barcode is read by the handy terminal 30 and the radio wave information is transmitted to the server 10, the radio wave intensity at the reading position can be specified. Further, by updating the detected radio wave intensity data 1441 and the detected radio wave map 1442 based on the specified radio wave strength, the latest radio wave distribution status can be easily specified, and the cause of the abnormality in the radio wave distribution can be determined. You can narrow down the area that is. Further, the content of the detection radio wave map 1442 may be included in the warning screen described above. This makes it possible to notify the user of the area that is the cause of the abnormality in the distribution of radio waves.

Next, a control procedure of the terminal-side inventory process executed in the handy terminal 30 and the server-side inventory process executed in the server 10 in order to execute the various operations related to the above-mentioned inventory will be described.

FIG. 14 is a flowchart showing a control procedure by the CPU 31 for the terminal-side inventory processing.
The inventory process is started when the user performs a predetermined input operation instructing the operation unit 35 to start the inventory work in the handy terminal 30.

When the terminal-side inventory processing is started, the CPU 31 causes the wireless communication unit 37 to acquire the radio wave strength from each access point 20, sets the access point 20 having the highest radio wave strength at that point as a communication connection target, and sets the access point 20 as a communication connection target. Start a communication connection. If any of the access points 20 is set as a communication connection target at the start of the terminal-side inventory processing and wireless communication with the access point 20 is possible, the processing in step S101. May be omitted.

The CPU 31 determines whether or not the user has instructed the operation unit 35 to read the barcode (step S102). If it is determined that the barcode reading instruction has not been given (“NO” in step S102), the CPU 31 executes the processes of steps S107 to S109 and roams as necessary. That is, the CPU 11 determines whether or not a predetermined standby time has elapsed since the last access point 20 to be connected to the communication was set (step S107). When it is determined that the predetermined standby time has elapsed (“YES” in step S107), the CPU 31 sets the access point 20 as a communication connection target based on the signal from the wireless communication unit 37. It is determined whether or not the radio wave intensity from is equal to or less than a predetermined reference value (step S108). When it is determined that the radio field strength is equal to or lower than the reference value (“YES” in step S108), the CPU 31 roams to the access point 20 having the highest radio field strength (step S109), and processes in step S102. Return to. The process of step S109 can be the same process as the process of step S101. When it is determined in the process of step S107 that the predetermined standby time has not elapsed (“NO” in step S107), or when it is determined in the process of step S108 that the radio field intensity is greater than the reference value (step S107). “NO” in S108), the CPU 31 returns the process to step S102 without roaming.

When it is determined in the process of step S102 that the barcode reading instruction has been given (“YES” in step S102), the CPU 31 causes the barcode scanner 38 to read the barcode and acquires the barcode information (step). S103). Further, the CPU 31 detects the intensity of the radio wave emitted from each access point 20 by the wireless communication unit 37, acquires the radio wave information, and stores the radio wave detection result data 343 in the storage unit 34 (step S104). Further, the CPU 31 causes the wireless communication unit 37 to transmit the acquired barcode information and radio wave information to the server 10 via the access point 20 (step S105).

The CPU 31 determines whether or not the inventory work has been completed (step S106). Here, the CPU 31 determines that the inventory work has been completed when the user performs an input operation instructing the operation unit 35 to complete the inventory work. If it is determined that the inventory work has not been completed (“NO” in step S106), the CPU 31 returns the process to step S102 in order to continue to receive the barcode reading instruction.
When it is determined that the inventory work is completed (“YES” in step S106), the CPU 31 ends the terminal-side inventory process.

FIG. 15 is a flowchart showing a control procedure by the CPU 11 for server-side inventory processing.
When the server-side inventory processing is started, the CPU 11 determines whether or not the inventory work is being continued at the handy terminal 30 (step S201). If it is determined that the inventory work is being continued (“YES” in step S201), the CPU 11 determines whether or not the barcode information and radio wave information have been received from the handy terminal 30 (step S202). If it is determined that the barcode information and the radio wave information have not been received (“NO” in step S202), the CPU 11 returns the process to step S201.

When it is determined that the barcode information and the radio wave information have been received (“YES” in step S202), the CPU 11 executes a predetermined process related to inventory based on the barcode information (step S203). Here, the CPU 11 stores the barcode information in the storage unit 14, and updates the management information related to the inventory of the product based on the barcode information.

The CPU 11 specifies the reading position when the handy terminal 30 reads the barcode based on the received barcode information and the position correspondence data 142 (step S204).

The CPU 11 determines whether or not the difference between the reference radio wave intensity corresponding to the reading position and the radio wave intensity indicated by the received radio wave information is equal to or greater than the reference difference (step S205). If it is determined that the difference is less than the reference difference (“NO” in step S205), the CPU 11 determines that there is no abnormality in the radio wave at the reading position and returns the process to step S201.

If it is determined that the difference is equal to or greater than the reference difference (“YES” in step S205), the CPU 11 determines that there is an abnormality in the radio wave at the reading position, and displays a predetermined warning screen on the display unit 36. (Step S206).

The CPU 11 generates the detected radio wave intensity data 1441 and the detected radio wave map 1442 based on the radio wave intensity indicated by the received radio wave information, and updates the contents if they have already been generated (step S207). When the process of step S207 is completed, the CPU 11 returns the process to step S201.

If it is determined in the process of step S201 that the inventory work has been completed (“NO” in step S201), the CPU 11 ends the server-side inventory process.

(Modification example)
Next, a modified example of the first embodiment will be described. This modification is different from the above embodiment in that the reading results of a plurality of barcodes are collectively transmitted to the server 10. The differences from the above-described embodiment will be described below.

FIG. 16 is a flowchart showing a control procedure by the CPU 31 of the terminal-side inventory processing according to the modified example.
The flowchart of FIG. 16 corresponds to a flow chart of FIG. 14 in which steps S101 and S105 are changed to steps S101a and S105a, respectively, and step S110 is added after step S104. Hereinafter, the differences from the flowchart of FIG. 14 will be described.

In step S101a, the CPU 31 performs a process of receiving inventory setting information from the server 10 in addition to a process of selecting the access point 20 and starting a communication connection. The inventory setting information includes information on the product to be inventoried, the barcode corresponding to the product, the theoretical inventory quantity of the product, and the like. The content of the received inventory setting information is reflected in the product inventory data 342 of the storage unit 34.

FIG. 17A is a diagram showing a content example of the product inventory data 342.
In the product inventory data 342, the barcode (“bar code B1” to “bar code B3”), product name (“product b1” to “product b3”) attached to the product, for each product to be inventoried, Contains information on theoretical inventory quantity and actual inventory quantity. Of these, the theoretical inventory quantity is the theoretical inventory quantity of products managed by the server 10 according to the purchase and sale of products. The actual inventory quantity is the actual quantity of the product counted by the actual product confirmation using the handy terminal 30, and at the time of step S101a, as shown in FIG. 17A, the data is not input. It has become.

When it is determined in step S102 that the bar code reading instruction has been made (“YES” in step S102), the CPU 31 causes the bar code to be read and the actual inventory quantity in the product inventory data 342 of FIG. 17 (a). Is counted up (step S103).

Next, the CPU 11 causes the wireless communication unit 37 to detect the intensity of the radio wave emitted from each access point 20, acquires the radio wave information, and stores the radio wave detection result data 343 in the storage unit 34 (step S104).

The CPU 31 determines whether or not the acquisition of the actual inventory quantity of the product corresponding to the most recently read barcode has been completed (step S110). Here, the CPU 31 determines that the acquisition of the actual inventory quantity is completed when the user performs a predetermined input operation for transmitting the information on the actual inventory quantity of the product to the server 10. If it is not determined that the acquisition of the actual inventory quantity is completed (“NO” in step S110), the CPU 31 returns the process to step S102 in order to continuously accept the input operation related to the reading of the barcode.

Each time the loop processing of steps S102 to S104 and S110 is repeated, the actual inventory quantity in the product inventory data 342 is counted up in step S103.
FIG. 17B is a diagram showing an example of the contents of the product inventory data 342 at the time when the reading of the barcode B1 of all the products b1 is completed. At this point, if the inventory quantity is appropriate, the actual inventory quantity for the product b1 will match the theoretical inventory quantity, as shown in FIG. 17 (b).

Further, every time the loop processing of steps S102 to S104 and S110 is repeated, the radio wave intensity data is accumulated in the radio wave detection result data 343 in step S104.
FIG. 18 is a diagram showing a content example of the radio wave detection result data 343.
The radio wave detection result data 343 has items of a reading barcode, a reading time, a radio wave intensity detection value of the first access point 20a, and a radio wave intensity detection value of the second access point 20b. Every time the process of step S104 is executed, a data line is added to the radio wave detection result data 343. One data line in the radio wave detection result data 343 corresponds to radio wave information. Therefore, the radio wave detection result data 343 includes a plurality of radio wave information.

When it is determined in the process of step S110 that the acquisition of the actual inventory quantity is completed (“YES” in step S110), the CPU 31 transmits the acquired barcode information and the plurality of radio wave information by the wireless communication unit 37. It is transmitted to the server 10 via the access point 20 (step S105a). The barcode information transmitted here includes information on the actual inventory quantity of the product corresponding to the read barcode. Further, the plurality of radio wave information to be transmitted is information included in the radio wave detection result data 343. When the process of step S105a is completed, the CPU 31 shifts the process to step S106.

The server 10 that has received the barcode information and the radio wave information executes the server-side inventory process of FIG. 15 as in the above embodiment.
In step S205 of this modification, when the radio wave detection result data 343 includes a plurality of radio wave information acquired at the same reading position, a plurality of radio waves of each access point 20 included in the plurality of radio wave information. A representative value of strength is used. The representative value can be an average value, a median value, a maximum value, a minimum value, or the like. In this modification, the accuracy of the detected value of the radio wave intensity can be improved by using the representative values of the plurality of radio wave intensities acquired at the same reading position in this way.
Instead of the method using the representative value, the abnormality of the radio wave may be detected by using each of the plurality of radio wave information.

Further, in step S207, the detected radio wave intensity data 1441 and the detected radio wave map 1442 are generated or updated based on the relatively new radio wave information among the received radio wave information. For example, as in the example shown in FIG. 18, the radio wave information at the time of reading the barcode B1 acquired from 15:00 to 15:01 and the radio wave information at the time of reading the barcode B2 acquired from 15:23 to 15:24. When the radio wave information of is received at once, the detected radio wave strength data 1441 and the detected radio wave map 1442 are first generated based on the radio wave information (representative value of the radio wave strength) at the time of reading the barcode B1, and then the bar. The content is updated based on the radio wave information (representative value of radio wave intensity) at the time of reading the code B2.
The detected radio wave intensity data 1441 and the detected radio wave map 1442 may be updated for each radio wave information without using the representative value.

Further, also in the first embodiment described above, the inventory work may be managed by using the product inventory data 342 in the handy terminal 30 as in the present modification.

As described above, the information acquisition management system 1 according to the first embodiment has the server 10, the access point 20 provided so as to be able to communicate with the server 10, and the server 10 via wireless communication with the access point 20.

The CPU 11 displays the bar code scanner 38 on the bar code scanner 38 based on the position correspondence data 142 in which the bar code and the information related to the position of the bar code are associated with each other and the bar code information received from the handy terminal 30. The reading position, which is the position of the handy terminal 30 when the code is read, is specified (reading position specifying means), and the reference radio wave indicating a predetermined intensity distribution of the radio wave emitted from the access point 20 as the reference information registered in advance. Abnormality of the radio wave emitted from the access point 20 is detected based on the comparison result between the reference radio wave strength corresponding to the reading position in the distribution data 143 and the radio wave strength indicated by the radio wave information received from the handy terminal 30. (Abnormality detection means).
According to this, the reading position of the handy terminal 30 can be specified based on the bar code information transmitted from the handy terminal 30. Therefore, the reading position can be easily specified even in the handy terminal 30 having a simple configuration that does not have a position acquisition means such as a GPS (Global Positioning System) device. Further, since the predetermined barcode position is specified as the reading position, almost no error occurs in the specified reading position unless the barcode is moved from the predetermined position. Therefore, the reading position of the handy terminal 30 can be specified with high accuracy.
Further, the intensity of the radio wave at the reading position can be specified based on the radio wave information transmitted from the handy terminal 30. Further, each time the bar code is read at different reading positions by the handy terminal 30, the radio wave intensity at the reading position is specified, and the radio wave intensity at a plurality of positions in the communication area 2 can be easily specified. By comparing these radio wave intensities with the reference radio wave strength of the reference radio wave distribution data 143, it is possible to easily detect an abnormality in the radio wave from the access point 20.

The radio wave distribution data 143 shows the intensity distribution of radio waves emitted from each of the plurality of access points 20. According to this, it is possible to easily detect an abnormality in radio waves emitted from a plurality of access points 20.

Further, the CPU 11 of the server 10 generates the detected radio wave distribution data 144 having the contents modified from the reference radio wave distribution data 143 according to the radio wave intensity indicated by the received radio wave information (information generation means). By referring to the detected radio wave distribution data 144, it is possible to easily identify the latest radio wave distribution status and narrow down the region that is the cause of the abnormality in the radio wave distribution.

Further, when the CPU 11 receives two or more radio wave information from the handy terminal 30, the CPU 11 updates the detected radio wave distribution data 144 based on the relatively new radio wave information (information generation means). By updating the detected radio wave distribution data 144 in this way, it is possible to obtain data close to the actual radio wave distribution status. Further, even when the radio wave distribution status is changing, the detected radio wave distribution data 144 can be updated to the content corresponding to the change. Further, when two or more radio wave information is received at one time as in the modified example, the two or more radio wave information is reflected in the detected radio wave distribution data 144 in the order according to the acquisition time of the radio wave information. Can be used effectively.

Further, the barcode is used for identifying the product to be identified, and the barcode information includes information related to the product identified based on the barcode read by the barcode scanner 38. According to this, the user only reads the barcode for the purpose of acquiring information related to the product such as inventory, and without any particular consciousness, obtains the radio wave information necessary for detecting the abnormality of the radio wave distribution. Can be collected.

Further, a barcode is attached to each of the plurality of products to be identified, and the wireless communication unit 37 is issued from the access point 20 each time the barcode scanner 38 reads the barcode of each of the plurality of products. The CPU 31 detects the intensity of the radio wave, and each time the bar code scanner 38 reads the bar code of each of the plurality of products, the bar code information and the radio wave information are transmitted by the wireless communication unit 37 to the server via the access point 20. 10 is transmitted (communication control means). According to this, it is possible to easily specify the radio wave intensity at a plurality of positions in the communication area 2 according to the reading of the barcodes of the plurality of products.

Further, the information acquisition management system 1 includes a display unit 16 that displays a predetermined warning screen when the CPU 11 detects an abnormality. According to this, it is possible to notify the user of the area causing the abnormality of the radio wave distribution.

Further, the server 10 according to the first embodiment has a CPU 11, and the CPU 11 has a position correspondence data 142 in which a barcode and information related to the position of the barcode are associated with each other, and a handy terminal 30. Based on the barcode information received from, the reading position, which is the position of the handy terminal 30 when the barcode scanner 38 reads the barcode, is specified (reading position specifying means), and the reference information registered in advance. Comparison result of the reference radio wave intensity corresponding to the reading position in the reference radio wave distribution data 143 showing a predetermined intensity distribution of the radio wave emitted from the access point 20 and the radio wave intensity indicated by the radio wave information received from the handy terminal 30. (Abnormality detecting means) for detecting an abnormality in the radio wave emitted from the access point 20 based on the above. By using the server 10 having such a configuration in the information acquisition management system 1, it is possible to easily detect an abnormality in the radio wave from the access point 20.

Further, the handy terminal 30 according to the first embodiment includes a wireless communication unit 37 that communicates with the server 10 via wireless communication with the access point 20, a barcode scanner 38 as a reading means for reading a barcode, and the like. Having a CPU 31, the wireless communication unit 37 detects the intensity of the radio wave emitted from the access point 20 when the bar code is read by the bar code scanner 38 (radio wave detecting means), and the CPU 31 The wireless communication unit 37 causes the wireless communication unit 37 to transmit the barcode information indicating the barcode read by the barcode scanner 38 and the radio wave information indicating the intensity of the radio wave detected by the wireless communication unit 37 to the server 10 via the access point 20 ( Communication control means). By using the handy terminal 30 having such a configuration in the information acquisition management system 1, it is possible to easily detect an abnormality in the radio wave from the access point 20.

Further, the program 141 according to the first embodiment uses the CPU 11 as a computer provided in the server 10 with the position-corresponding data 142 in which the barcode and the information related to the position of the barcode are associated with each other. , A reading position specifying means for specifying a reading position, which is the position of the handy terminal 30 when the barcode scanner 38 reads the barcode, based on the barcode information received from the handy terminal 30, is registered in advance.

(Second embodiment)
Next, a second embodiment of the present invention will be described. This embodiment is different from the first embodiment in that the information of the connected access point 20 is used instead of the radio wave information indicating the strength of the radio wave. Hereinafter, the differences from the first embodiment will be described.

In the information acquisition management system 1 of the second embodiment, the access points to be normally connected at the positions of the respective barcodes according to a predetermined distribution (distribution at the time of site survey) of radio waves emitted from the plurality of access points 20. 20 (hereinafter referred to as "specified access point") is specified in advance. The specified access point associated with each barcode is the access point 20 having the highest radio field strength at the position of the barcode.

FIG. 19 is a diagram illustrating a method of specifying a specified access point.
In FIG. 19, the positions PB4 to PB6 of the barcodes B4 to B6 are shown in the horizontal axis direction. Further, in the vertical direction, the distribution of the radio wave intensities of the first access point 20a and the second access point 20b at each position is shown by broken lines. In the example of FIG. 19, at the position of the barcode B4, the radio field strength of the first access point 20a is higher than the radio field strength of the second access point 20b. Therefore, the specified access point corresponding to the barcode B4 is specified as the first access point 20a. Further, at the positions of the barcodes B5 and B6, the radio field strength of the second access point 20b is higher than the radio field strength of the first access point 20a. Therefore, the specified access point corresponding to the barcodes B5 and B6 is specified as the second access point 20b.

FIG. 20 is a block diagram showing a main functional configuration of the server 10 according to the second embodiment.
In the storage unit 14 of the server 10 of the present embodiment, instead of the reference radio wave distribution data 143, the specified access point data 145 indicating the specified access point at the position of each barcode is stored. Further, instead of the detected radio wave distribution data 144, the modified specified access point data 146 in which the specified access point data 145 is modified is stored. Of these, the specified access point data 145 is pre-registered reference information that is referred to when detecting an abnormality in radio waves.

FIG. 21 is a diagram showing a content example of the specified access point data 145.
In the specified access point data 145, the position of each barcode is associated with the specified access point at the position.
