Description

  The present invention relates to a guidance system and a guidance method for guiding a plurality of guided persons in a predetermined area along a route set individually for each guided person, and in particular, guidance for smoothly guiding a patient in a hospital. The present invention relates to a system and a guidance method.

  Conventionally, in order to efficiently guide a plurality of guided persons on different routes within a predetermined area, a device has been devised. In particular, in the case of a general hospital, the path of movement for each patient is different, and the overall efficiency of guidance cannot be achieved even if the conductor is designed assuming only the route of a specific movement pattern.

  In addition, in the course of guidance including in-call call waiting status, the hospital side must make a call with personal information such as name and so on so that no mistakes will occur. Auxiliary work is stressed. There is a risk that the extraordinary work related to such guidance may interfere with the main business, and in some cases, the extraordinary work accounts for nearly 30% of the total work.

  In order to solve the above problems, various techniques have been proposed. For example, a patient guidance system has been proposed in which a small FM radio wave transmitter / receiver is delivered to a patient and guidance information is provided to the small FM radio wave transmitter / receiver by voice guidance by an operator at a center (see, for example, Patent Document 1).

  In addition, a guidance system has been proposed that accepts an examination order through user authentication based on an ID given to a patient and guides directions using a terminal device fixedly installed in the hospital (see, for example, Patent Document 2).

  Furthermore, the patient's waiting time is calculated for each department by causing the reading device to read an examination ticket equipped with an electronic chip storing patient information, and this is displayed on a terminal fixedly installed in the hospital. A patient guidance system that displays a consultation route has been proposed (see, for example, Patent Document 3).

JP 7-334579 A JP 2000-3400 A Japanese Patent No. 3474530

  However, according to the prior art according to Patent Document 1, since a dedicated small FM radio wave transmitter / receiver is required for each patient, the system construction is costly and the system is premised on communication with an operator. There was a personal element depending on the skill of the operator, and there was a possibility that a uniform service could not be provided.

  In addition, according to the prior art according to Patent Document 2, although the aspect of personal information protection can be solved to some extent through user authentication based on ID, a route is required unless the patient himself / herself operates a terminal fixedly installed in the hospital to some extent. Therefore, if there is no terminal in the place where the route needs to be confirmed, the terminal must be returned to the place where the terminal is installed. The assistant on the side has to guide to the place where the terminal is installed or explain the operation, and there is a disadvantage that the solution of the problem of reducing the extraordinary work becomes insufficient.

  Furthermore, according to the prior art according to Patent Document 3, by using an electronic chip, it is expected to be much more portable than Patent Document 1 and to improve the reliability of protection of personal information. Is done.

  By the way, in the hospital examination and examination, the initially set order is often changed. In particular, in view of balance with the progress of other patients, conventionally, the examination order and examination order have been appropriately changed based on the empirical rules of nurses and the like. However, such a change causes a description of guidance for the patient and a load of auxiliary guidance. Such a change in order is an indispensable operation from the viewpoint of reducing the waiting time of the patient, but it cannot be denied that this may lead to an increase in load for the hospital. Each of the above prior arts does not present any solution for such a problem.

  As described above, the prior art has been described by taking patient guidance in a hospital as an example. However, in a predetermined area, as long as it guides a plurality of guided persons by different routes, not only patient guidance in a hospital, For example, a similar problem may occur even when a plurality of routes are set in a relatively large exhibition hall or the like.

  The present invention is for solving the above-mentioned problems. In a predetermined area, a plurality of guideees with different routes are protected for personal information, and each individual is identified and smoothly routed. It is an object to provide a guidance system and a guidance method for guiding.

In order to achieve the above object, a guidance system according to the present invention is a guidance system that guides a plurality of guided persons in a predetermined area along a route set individually for each guided person,
ID generating means for setting and generating a unique ID for each guided person,
Storage means for generating and storing guidance information by associating the individually set route information with each of the generated ID information;
ID input means for reading each guidance information from the storage means and registering the ID information in a recording medium that can be worn on or carried by each guided person's body;
When each guided person wearing or carrying the recording medium in which the ID information is registered moves along the route, a plurality of pieces of ID information transmitted from the recording medium of each guided person are installed in the area. Receiving means for sequentially sensing and receiving each sensed ID information;
An encryption processing means for reading out the guidance information corresponding to each received ID information from the storage means, performing a predetermined encryption process on the read guidance information, and generating encrypted information;
Transmitting means for transmitting the encrypted information to each recording medium;
Have
Each of the transmitted encrypted information is such that only the encrypted information consisting of the guidance information corresponding to the ID is decrypted by the ID information registered in the recording medium worn or carried by each guided person. It is the main feature to be characterized by being.

  According to this configuration, by assigning a unique ID to the guided person, all operations related to the subsequent guidance can be managed by using the ID, and the guided person is active in order to acquire route information. It is guided by a route set in a timely manner without being conscious of a typical operation.

The ID set in the present invention is given for a limited time within a predetermined closed area. Therefore, when the sensing unit senses that the guided person has reached the final destination of the route, the ID may be invalidated and the invalidation unit may be configured to delete the guidance information from the storage unit. .

  Moreover, it is good also as a structure which has an operation | movement control means to operate | move the device used for a to-be-guided person's guidance with the said decoding. Here, the device displays at least one of door opening means for allowing the guided person to enter a predetermined area within the area and guidance information as one or more of character information, image information, and voice information. Any display means may be used. However, the guidance information displayed by the display means is separated to a distance at which the recording medium cannot sense the ID information registered in the recording medium by the sensing means in order to protect the personal information of the guided person. Then, it is preferable to erase the data.

  The encryption processing means is not intended to generate a cipher for permanent use, but is used in an environment where a request for sequential decryption is made, and can be decrypted immediately. is necessary. Therefore, for example, the guidance information read from the storage means is encrypted sequentially or simultaneously, and identification information for identifying the guidance information corresponding to each ID is attached to generate encrypted information. It is preferable that a combination unit that generates an encrypted information group by combining the respective pieces of encrypted information including the information is transmitted to the recording medium by the transmission unit.

  In order to prepare for unforeseen circumstances, the guider side needs to track the behavior of each person being guided in real time. Therefore, log data generating means for generating log data for each guided person according to each ID information acquired by the sensing means when the guided person wearing or carrying the recording medium passes, and the generated log It is good also as a structure provided with the monitoring means which enables browsing of data. Further, the route information includes a plurality of area information where the guided person stops, and when the sensing unit senses that the guided person sequentially stops in each area according to a route set in the route information, The log data generation means may generate log data having stop-by information.

  By the way, due to mistakes of the guided person, convenience on the part of the guide, and the like, it is not always possible to stop at each area according to the route originally set up to the final destination. Conventionally, in such a case, work such as reassembling the route has been required. Therefore, in the guidance system according to the present invention, when it is detected that the guided person has accessed the area in an order different from the order of the area according to the route, the log data including the stop information and the area information are included. The monitoring unit has a function of comparing the route information and displaying the instruction information for returning to the route in the order set in the route information on the display unit. On the other hand, there is a case where it is preferable to change the route as it is instead of instructing the return even in an order different from the order of the stoppages set at the beginning. Therefore, the area information included in the route information includes a table in which course patterns in different orders within a variable range of the order are registered together with a stop order according to the route, When detecting that the areas are accessed in an order different from the stop order, the monitoring unit compares the log data having the stop information with the route information including the area information, and determines the areas accessed in the different order and the order. A corresponding course pattern may be read from the table, and route change means may be provided for changing the order of stop according to the route of the area information to the order according to the read course pattern.

In order to achieve the above object, a guidance method according to the present invention is a guidance method for guiding a plurality of guided persons through a route set individually for each guided person through a management server in a predetermined area. There,
Requesting the management server to set and generate a unique ID for each guided person;
Associating the individually set route information with each of the generated ID information, generating guidance information, and storing it in the management server;
Reading each stored guidance information and registering ID information on a recording medium that can be worn or carried on each guided person's body; and
When each guided person wearing or carrying the recording medium in which the ID information is registered moves along the route, a plurality of pieces of ID information transmitted from the recording medium of each guided person are installed in the area. The sensing means sequentially senses, and the management server receives each sensed ID information;
The guidance information corresponding to each received ID information is read out, and the read guidance information is sequentially or simultaneously generated as encrypted information by a predetermined encryption method, and the generated encrypted information is assigned to each ID. A step of uniquely identifying identification information, and
Combining the encrypted information to generate an encrypted information group;
Transmitting the encrypted information group to the recording media;
Based on the identification information, the ID information registered in the recording medium attached to each guided person identifies the guidance information corresponding to the ID from the transmitted encrypted information group, and the guidance information identified. Decrypting only, and
It has the most important feature.

  According to this method, the set route can be guided only by the ID individually set for the guided person, and the personal information is encrypted, while the decryption request of each guided person is frequently received. And smooth processing can be executed.

The route information includes a plurality of pieces of area information for the guided person to stop. When the sensing unit senses that the guided person has sequentially visited each area according to the route set by the route information, the route information stops. Generating log data having information, and when the detecting means detects that the guided person has accessed the area in an order different from the order of the area according to the route, the management server The step of comparing the log data having information with the route information including the area information and the instruction information for returning to the route in the order set in the route information are one or two of character information, image information, and voice information. And generating the instruction information on a display means that can be browsed by the guided person. By modulo, it can maintain the induction in accordance with the route initially set.

  On the other hand, in the area information included in the route information, a step of generating a table in which course patterns in different orders within a variable range of the order are registered together with a stop order according to the route, When the detecting means detects that the areas are accessed in an order different from the stop order of the log, the management server compares the log data having the stop information with the route information including the area information, and the different order. It is also possible to cope with a method having a step of reading out the accessed area and the course pattern corresponding to the order from the table and changing the stop order according to the route of the area information to the order according to the read course pattern. By doing so, the route can be changed even during the guidance.

  The guidance system and the guidance method according to the present invention can smoothly guide a route by specifying each individual while protecting personal information to a plurality of guided persons on different routes within a predetermined area. There is an effect that it becomes possible.

In particular, the personal information is disclosed to others for the guided person because the personal secret is completely retained in the movement within the predetermined area, and the call is unnecessary with the content corresponding to the personal information in the area. It is possible to receive a smooth guidance of the route in the area while keeping the personal information secret, so that the physical burden is also reduced.

In addition, for the inducer, the burden of extraordinary work related to guidance is reduced, and as a result of being able to concentrate on this work, for example, the work environment on the inducer can be expected to be improved and management efficiency can be expected.

  The guidance system and the guidance method according to the present invention can be applied as long as they can simultaneously or sequentially guide a plurality of guided persons on different routes within a predetermined area, and the application is not particularly limited. Typically, it is assumed that the predetermined area is a hospital (particularly a general hospital) and is used for guidance in a hospital where the person to be guided is a patient. Therefore, hereinafter, in the present embodiment, an example applied to a system for guiding a patient in a hospital will be described.

  Referring to FIG. 1, reference numeral 1 denotes a management server for a guidance system according to the present invention. In the present embodiment, for convenience of explanation, one management server 1 is provided with each function. However, according to the installation environment or the like, each function can be implemented by using a separate device and various servers on a communication network as appropriate. It may be connected to realize a similar function. In other words, the guidance system or guidance method according to the present invention is not intended to limit all functions described below to a mode in which one management server 1 is provided.

  The management server 1 (or, as described above, a separate device and a variety of separate servers) is mainly composed of a central processing unit (CPU), a main memory, a magnetic disk, and other peripheral devices. The CPU mainly controls the operation of each component of the guidance system according to the present invention. The main memory stores a control program executed by the CPU, and provides a work area when the CPU executes the program. The magnetic disk stores various applications including an operating system, a peripheral device drive, and a program for performing guidance according to the present invention.

  The present invention has a mechanism for guiding a patient smoothly without having to be aware of a special operation for route guidance for a patient who is a guided person, by simply guiding the route by simply moving in the hospital. . In addition, while identifying individual patients, personal information of each patient is disclosed to other patients, other hospital staff not related to the patient, and collation with other systems used in general medical services. It has a mechanism that is not done. In order to realize such a mechanism, a configuration is adopted in which a patient ID tag T including an IC chip is attached to and carried by the patient as a recording medium that mediates communication between the management server 1 and the patient. The patient ID tag T includes at least a memory for storing an ID, which will be described later, and an antenna for communicating information such as the stored ID with the sensor and the management server 1 by a non-contact power transmission technique. . In addition, the patient ID tag T must be held by the patient in a form that does not hinder the operation and behavior until the patient completes the examination, examination, treatment, and office procedure at the hospital. Or what can be carried is good. For example, a format in which an IC chip is mounted on a wristband type is preferable. A patient can receive various services related to in-hospital guidance via the short-range wireless technology by attaching the patient ID tag T or the like. However, the recording medium is not limited to the IC chip as long as it does not deviate from the above.

  The patient makes a reservation procedure by disclosing the patient's personal information at the telephone call before the visit, the Internet, etc. or at the reception at the visit. The patient personal information at the time of reservation is recorded in the reservation recording unit 113 of the management server 1. Thereafter, when the patient moves in the hospital, an ID for associating the personal information with the patient is assigned in order to identify the patient without disclosing the personal information of the patient. That is, the management server 1 includes an ID input unit 111 that receives an ID assignment request for the patient ID tag T, ID information unique to each patient in response to the received request, and route information in the ID information. And an ID generation unit 112 that generates guidance information that associates instruction contents to patients mainly (hereinafter, in this specification, information related to instruction contents such as ID information and route information is generically guided. Called information). When the guidance information is set by the ID generation unit 112, the set ID information is registered in the patient ID tag T by the ID input unit 111, and the guidance information is stored in the storage unit 114. The ID input unit 111 may include a display unit (display) for confirming guidance information of each patient.

  The patient is identified by the set ID during a short period of stay in the hospital, and in many cases, the disclosure of personal information is avoided. Because it is for others, for example, a credit card, it is a temporary one, not a place that keeps security for long periods of time, regardless of location, so patients accept it at the hospital Then, for example, the ID may be valid until the last accounting process. Therefore, when the management server 1 acquires the final destination arrival information of the patient (for example, acquires information on the end of the transaction), the management server 1 may include an invalidation processing unit that invalidates and deletes the ID (see FIG. Not shown). Such invalidation processing unit can also prevent ID depletion.

  When a patient wearing an ID registered patient ID tag T moves in the hospital, ID information is detected by a non-contact sensor unit S that can communicate with the patient ID tag T. This sensor part S is installed in multiple places so that a patient's movement can be tracked without omission according to the structure and installation environment of a hospital. As described above, since the sensor unit S senses without contact, it does not require active operation of the patient, and can be sensed only by the patient moving normally.

  The detected ID information is received from the sensor unit S by the receiving unit 115 of the management server S. The guidance information corresponding to the received ID information is read from the storage unit 114, and encrypted information is generated by an encryption processing unit 117 that performs a predetermined encryption process to be described later. The generated encrypted information is transmitted from the transmission unit 118 of the management server 1 to the patient ID tag T in which the detected ID information is registered.

  The transmitted encrypted information is decrypted into guidance information by the ID information registered in the patient ID tag T and used for guidance of the patient. At this time, since the sensed sensor senses the movement of a plurality of patients, the encrypted information transmitted from the transmission unit 118 is transmitted from the plurality of patients simultaneously or sequentially. However, as will be described later, the encryption process is uniquely generated for each ID and is decrypted only by the ID. Therefore, even if the encryption information of another person is received, the encryption process is performed. What is obtained is only guidance information corresponding to his / her ID. By adopting such a configuration, the personal information of the patient is protected without being disclosed to others. In addition, by constructing a wireless sensor network that transmits and receives information among the patient ID tag T, the sensor unit S, and the management server 1, processing that does not involve human (patient) operation (processing by a so-called M2M system) As a result, there is no need for manual operation for route confirmation as in the past. As a result, not only the mental and physical burden on the patient is reduced, but also the guidance of nurses and other hospitals It can also be expected to contribute to reducing the burden of extraordinary work related to. The wireless sensor network is not particularly limited as long as it collects sensor information and enables two-way communication. However, the wireless sensor network is based on a communication standard compliant with IEEE 802.15.4. It is preferable to construct.

  The management server 1 obtains, from the sensor unit S, log data of the location where the sensor unit S is installed and the time when the sensor unit S is passed, in addition to the ID information, and passes this to the monitoring unit 116. The monitoring unit 116 requests the log data generation unit 119 to generate log data in association with the received ID information, which includes the acquired log time and passage location. The generated log data is stored in the storage unit 120. The monitoring unit 116 can read the generated log data from the storage unit 120 and browse as appropriate. Therefore, the monitoring unit 116 allows the hospital to track the movement log data in the patient's hospital in real time. For example, the patient is in a physical condition and cannot move during the movement in the hospital. In case of emergency, we can take emergency measures.

  In the case of a hospital, the route information includes a plurality of areas where patients stop by, for example, an examination room, an examination room, a treatment room, and an accounting window. Therefore, the sensor unit S is provided in the area, and the log data generation unit is based on ID information obtained by sensing of the sensor unit S when the patient stops in each area according to the route set in the route information. Drop-in information can be included in the log data. By obtaining stop-by information, it is possible to clearly grasp the progress of examination, examination, and treatment.

In the present embodiment, in the generation of the encryption information by the encryption processing unit 117, the reading of the guidance information corresponding to the received ID information from the storage unit 114 is performed by passing the ID information to the monitoring unit 116. However, the present invention is not limited to this unless it is contrary to the spirit of the present invention. Therefore, for example, the receiving unit 115 may directly pass data to the storage unit 114.

  By the way, when the patient is instructed to stop by several places, for example, in addition to reception, accounting, instructed for examination, examination, treatment, etc., or when the conductor is difficult to understand, such as a branch point in a hospital, It is convenient if the route information is displayed by a display device or the like as appropriate so that only the patient can view it, or the door opening device is operated by ID information in order to authenticate the person when entering the examination room. It is. Therefore, the management server 1 may include a control unit 121 that activates a device used for patient guidance together with the decryption.

  Among the devices, the display device displays the guidance information as one or more of character information, image information, and audio information, for example, digital signage. The display device includes a device such as a small display unit provided in the patient ID tag T in addition to a device fixedly installed in a hospital. However, the device is provided for patient guidance and may be operated by the ID information, and is not limited to the door opening device and the display device.

  By the way, in the case of the said display apparatus, the thing of the structure in which display content can be browsed open like digital signage can also be browsed by others, and is not preferable from a viewpoint of personal information protection. Therefore, the sensor unit S included in the display device itself or the sensor unit S in the vicinity of the display device displays guidance information displayed on the display device when the patient is separated to a distance where the ID information of the patient ID tag T cannot be detected. May be provided (not shown).

  FIG. 2 is a schematic diagram showing the processing contents of the encryption processing unit 117 of the guidance system according to the present invention. The encryption processing unit 117 encrypts the guidance information of a plurality of patients sequentially or simultaneously. In the present embodiment, a process for encrypting the guidance information of patient A and patient B is shown.

When the encryption processing unit 117 reads the guidance information for the patient A (plain text Ap) and the guidance information for the patient B (plain text Bp) from the storage unit 114 illustrated in FIG. 1, encrypted information generation units 117a and 117b described later. To generate encryption information Ac and Bc, respectively. The generated encrypted information is sequentially queued and combined, for example, by the combining unit 117c. The combined information forms an encrypted information group ABj and is transmitted to the patient ID tag T via the transmission unit 118 described in FIG. The encrypted information group ABj is received by both the patient ID tag Ta of the patient A and the patient ID tag Tb of the patient B, but each patient ID tag Ta, Tb can be decrypted by each ID information. Decrypt information only. Therefore, the patient ID tag Ta acquires only the plain text Ap, and each patient ID tag Ta acquires only the plain text Bp.

  In order to identify encrypted information that can be decrypted by the ID information registered in each patient ID tag T from the combined encrypted information group, a configuration as shown in FIG. 3 may be used. That is, in the encrypted information group AB-Nj, for example, the encrypted information A may be formed as a communication format including identification information Ah that is uniquely determined by each ID information in addition to the encrypted guide information Ab. Therefore, in this case, the encryption information generation units 117a and 117b of FIG. 2 may add the identification information to each encryption information when generating the encryption information.

  FIG. 4 is a diagram showing (a) encryption processing steps of the encryption information generation units 117a and 117b and (b) decryption processing steps of the patient ID tags Ta and Tb. When the guidance information P to be encrypted is read from the storage unit 114, dummy information ODD is added to the read guidance information (plain text P) as shown in FIG. 4A to obtain encrypted information C1. In this embodiment, an example in which a dummy bit is added to an odd number (ODD) position of a bit of plaintext P has been shown, but a method such as bit transposition and replacement may be used.

  As described with reference to FIG. 3, the identification information H uniquely determined by the ID information is added to the encryption information C1 to obtain the encryption information C2. Further, the identification information H may be transposed, replaced, etc. accompanying the ID information.

  After obtaining the encrypted information C2, the whole is scrambled by the ID information, and combined with other scrambled encrypted information from the combining unit 117c described in FIG. Encryption information C3 that can be transmitted to the business ID tag T is obtained.

  On the other hand, as shown in FIG. 4B, when the encrypted information C3 is received as the decrypted information D3 by the patient ID tag T, it is descrambled by the ID information to obtain the decrypted information D2. From the decryption information D2, the identification information H determined in advance by the ID information is detected, the information is recognized as being addressed to itself, and the decryption information D1 is obtained. The dummy information ODD added to the odd positions is deleted from the decryption information D1, and the plaintext P is obtained.

  As in the present invention, when the information is used for a limited time and it is required to speed up the throughput of the encryption and decryption processing with priority, the encryption as shown in FIG. Processing is preferred.

  By the way, the patient does not always move along the route indicated by the route information instructed at the time of reception. For example, if you stop by the toilet in the middle of a move, or if you have a long waiting time, if you stop outside the hospital, or if you leave the route specified by the misunderstanding, it will return to the normal route smoothly. However, there are many cases where it is not possible to return to the normal route by oneself. In addition, when a large number of people are distributed to each examination item and examined in parallel, such as a group examination, the average required time per person differs depending on the examination item, so a long queue only for a specific examination item In order to prevent this from happening, it is common practice to change the originally scheduled examination order at the hospital's discretion. As described above, when the patient accesses in a different order from the stop order according to the originally set route, guidance processing for returning to the original route and guidance processing for changing the guidance order are required.

  First, in the guidance process for returning to the original order, the monitoring unit 116 described with reference to FIG. 1 includes a comparison unit (not shown) that compares the route information included in the original guidance information with the drop-in information. The instruction information for returning to the route in the order set by the route information may be generated, and the generated instruction information may be displayed on the device D (display device) via the control unit 121.

  On the other hand, in the guidance process for changing the guidance order, as shown in FIG. 5, the management server 1 has a table of course patterns to be changed in advance, and the monitoring unit 116 is included in the initial guidance information as described above. A comparison unit (not shown) for comparing the route information and the stop-off information is provided, and the places arrived in the order different from the original and the course pattern corresponding to the order are read from the table, and the route of the area information is What is necessary is just to provide the path | route change part which changes the order which followed according to the order according to the said read course pattern (not shown). For example, in FIG. 5, it is assumed that the originally planned route is course patterns a 1, 2, and 3 when there are three places of stops, i, b, and c. However, if the place where the patient first visited is B, it is sufficient to accept the change in which the first place to stop is B and change the course pattern to c or d.

  The course pattern of FIG. 5 can be set in a permutation according to the number of places to stop by, but in reality, there are a mixture of those that can be changed and those that cannot be changed. There are many cases. For example, in the case of the first visit, if the start always starts with an inquiry, it is necessary to fix the beginning of the course pattern. Therefore, in such a case, for those in which the order is fixed, the order is fixed in the course pattern table and the instruction information for return is displayed, and the other order is the route changing unit. The process according to the above may be performed.

  FIG. 6 is a schematic sequence diagram showing the guiding method according to the present invention. In this embodiment, as described at the beginning, a configuration in which one management server 1 is provided is described as an example. However, for convenience of explanation, the storage unit is described as a separate object. In addition, the code | symbol of each object uses what was attached | subjected in FIG.

  First, the management server 1 is requested to set and generate IDs for a plurality of patient ID tags T (S111). The management server 1 generates guidance information by associating the generated ID information with the path information set for each patient individually, and stores the guidance information in the storage unit 114 (S112). The stored guidance information is read (S113), and the ID information is registered in each patient ID tag T (S114).

When each patient wearing the patient ID tag T in which the ID information is registered moves along the route, the sensors S installed at a plurality of locations in the region include the ID information transmitted from the patient ID tag T. Sequential sensing is performed (S115). When the management server 1 receives each sensed ID information (S116), the management server 1 reads out guidance information corresponding to each received ID information from the storage unit 114 (S117). The read guidance information is generated as encrypted information sequentially or simultaneously by a predetermined encryption method (S118), and identification information uniquely corresponding to each ID is attached to the generated encrypted information.

The generated encrypted information is combined to generate an encrypted information group (S119), and the encrypted information group is transmitted to each patient ID tag T (S120). From the transmitted encrypted information group, the ID information registered in the patient ID tag T attached to each guided person has identified and identified the guidance information corresponding to the ID by the identification information. Only the guidance information is decrypted (S121), and predetermined guidance information can be acquired.

  By the above guidance method, the set route can be guided only by the ID information individually set for the patient, and the personal information is encrypted, while the frequent decryption request of each patient. Smooth processing can be executed.

FIG. 7 is a flowchart showing the processing of the guidance method with route return or route change. As an embodiment, a guidance method corresponding only to route return or route change is also assumed, but as described above, at least in guidance in a hospital, a guidance method that properly uses both as a course pattern is normal. Therefore, FIG. 7 shows a guidance method for using both in combination. In the present embodiment, places where patients stop (for example, examination rooms, examination rooms, treatment rooms, accounting) are collectively referred to as “areas”.

  The route information includes a plurality of pieces of area information where the guided person stops. When the sensor unit S senses that the guided person has sequentially visited each area according to the route set by the route information (S201), the route information stops. Log data having information is generated (S202).

When the sensor unit S detects that the guided person has accessed any area, the management server 1 compares the log data having the drop-in information with the route information including the area information, and the area outside the normal route Whether or not (S203). When it is determined that the area has reached the normal route (N in S203), the sensor unit S senses the access to the next area of the patient, and repeats the processing from S201 to S203. On the other hand, if it is determined that the operation has been performed in an area outside the normal route (Y in S203), the log data is compared with the route information (S204), and the course pattern table described with reference to FIG. 5 is referred to (S205). The course pattern table may be generated in advance and registered in the management server 1.

By referring to the course pattern table, it is determined whether or not there is a course pattern that matches the course pattern in the case of reaching the off-route area in the order (S206). If there is no matching course pattern (N in S206), return information for returning to the course pattern of the normal route is generated by one or more of character information, image information, and audio information (S209), and the generated return information is generated. Is displayed on a display device that can be viewed by the patient (S210). On the other hand, when there is the matching course pattern in the course pattern table (Y in S206), the matching course pattern is read from the course pattern table (S207), and the stop order according to the route is determined according to the read course pattern. The change is registered in the order (S208).

In the case of guidance only by route return, it is only necessary to immediately jump from S204 in FIG. 7 to S209 to generate return information. In the case of guidance only by route change, S206 and S209 in FIG. And the step of S210 may be omitted.
