Description

  The present invention relates to a security system.

Conventionally, for the purpose of improving crime prevention in buildings, security sensors that detect the presence or absence of people have been installed in buildings or grounds, and a warning is issued when the security sensors detect that a suspicious person has entered the building or grounds. Various security systems have been proposed (see, for example, Patent Document 1). In the security system of Patent Literature 1, when security sensors are provided in the security areas such as the entrance, the window, and the gate, respectively, and a person who performs suspicious behavior in the site is detected based on the detection results of those security sensors A warning is issued to that person.
JP 2007-233660 A

  However, in the crime prevention system of Patent Document 1 described above, since the presence of a suspicious person is detected based on the action in the alert area and a warning is issued, the suspicious person is allowed to enter the alert area itself, which is preferable for crime prevention. Not necessarily. On the other hand, in order to improve the security performance, it is desirable to set the detection area of the security sensor as wide as possible (for example, almost the entire site). However, in that case, even if a person who is allowed to enter the site, such as a resident or a visitor, enters the detection area, a warning is issued when entering the site, just like a suspicious person. There is a concern that

  This invention is made | formed in view of the said event, and makes it a main objective to provide the crime prevention system which can implement appropriate crime prevention according to a visitor classification.

  The present invention employs the following means in order to solve the above problems.

  The present invention is a person detection means for detecting the presence or absence of a person in each site area as a detection area each of a plurality of site areas defined in a site including a building, a visitor determination means for determining a visitor type, In accordance with the visitor type determined by the visitor determination means, an area setting means for setting any one of the plurality of premises areas as a warning area, a warning means for performing a warning, and the area setting means Control means for performing a warning by the warning means when the person detection means detects that a person is present in the set warning area.

  In general, there are places where visitors are allowed to enter and places where entry is not allowed, and permission / non-permission to each place may differ depending on each visitor. For this reason, if a warning is given to a visitor in the same manner, a warning will be issued to the person who is allowed to enter when entering the place. On the other hand, if the entry restriction is relaxed, even the entry of a person who is not allowed to enter (suspicious person) is allowed, and an appropriate warning cannot be given to the suspicious person. In this regard, according to the present invention, when there is a visitor, according to the type of the visitor, it is set which one of the plurality of premises areas to be a warning area, and the person in the warning area A warning is given when it is detected. Thereby, it is suppressed that a crime prevention system reacts excessively with respect to persons other than a suspicious person, being wary of the invasion of a suspicious person. Therefore, appropriate crime prevention can be implemented according to the visitor type.

  In the present invention, the area setting means sets a permission area other than the warning area among the plurality of premises areas, and the control means sets a stay permission time in the permission area according to the visitor type. In addition, when the person detection unit detects that there is a person in the permission area beyond the set permission time, a warning by the warning unit may be performed. Even if it is a place where entry is allowed, if a visitor stays at the place for an unreasonable amount of time, the behavior is unsuitable and considered suspicious. It is done. In addition, the stay time determined to be suspicious may vary depending on the visitor. Therefore, by setting the permission time for staying in a place where entry is permitted according to the visitor type, it is possible to suitably eliminate suspicious persons and improve crime prevention performance. At this time, it is desirable to set the stay permission time according to the alert level for the visitor. Specifically, it is desirable to shorten the stay permit time for a visitor with a higher alert level.

  In the present invention, the area setting means is a permission area other than the warning area among the plurality of in-site areas, and the control means sets a permission time zone for entering the permission area according to the visitor type. In addition to setting, when the presence of a person is detected by the person detection means in the permission area in a time zone other than the set permission time zone, a warning by the warning means may be implemented. Even if it is a place where entry is permitted, if a visitor enters the place during a time zone that does not meet the requirement, the visitor's behavior is not appropriate to the requirement and is considered suspicious. It is done. Moreover, it is possible that the time slot | zone judged as suspicious changes according to a visitor. Therefore, by setting the permitted time zone for entering the place where entry is allowed according to the visitor type, it is possible to suitably eliminate suspicious persons and improve crime prevention performance.

  In the present invention, the control means may set a warning level according to a visitor type determined by the visitor determination means, and may perform a warning by the warning means in a mode according to the set warning level. Good. According to this configuration, since the warning mode is changed according to the visitor type, it is possible to suppress an excessive warning to a weak-visited visitor, while being intimidating for a highly-visited visitor. High warning can be implemented.

  In the present invention, it comprises schedule storage means for storing visit schedule information related to a visit schedule, wherein the visitor determination means determines the visitor type based on the visitor declaration, and the control means comprises: When the visitor type determined by the visitor determination means is not stored as the visit schedule information in the schedule storage means, the person detection means detects that there is a person in at least one of the plurality of premises areas. In such a case, a warning by the warning means may be performed. According to this configuration, a warning is issued when the visit requirement differs between the visit schedule registered in advance and the visitor's declaration. It is possible to prevent spoofing.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, the top view of a building provided with the crime prevention system of this embodiment is shown.

  In FIG. 1, a building 10 is provided on a site 11. In addition, the site 11 is provided with various spaces each having a different use, except for the building space of the building 10. In this embodiment, there are an approach 13, a parking space 14, a garden space 15, a side passage space 16, a backyard 17 and the like as various spaces.

  The approach 13 is a passage space from the front doorway 18 arranged at the outer edge of the site 11 to the entrance 19 of the building 10, and is mainly used when residents and visitors go back and forth between the entrance 19 and the outside of the site. In the vicinity of the approach 13, a mailbox 21 and a delivery box 22 are provided. The parking space 14 is a space where the vehicle C can be parked, and is provided adjacent to the approach 13 in FIG.

  The garden space 15 is a space that is used for multiple purposes (for example, entertainment and planting) by residents, and in this embodiment, in the area opposite to the parking space 14 with respect to the approach 13 from the front of the building 10 to the back. Are provided. The side passage space 16 is a space provided in the gap between the outer edge of the site 11 and the building 10, and various meter facilities 23 such as an electric meter and a water meter are disposed therein. The backyard 17 is a space provided on the back side of the building 10 and is used as, for example, a clothes drying place or a bicycle storage place.

  Next, the security system will be described. This crime prevention system issues a warning when it is detected that there is a person in the alert area defined in the site 11 in order to eliminate a suspicious person who has entered the site 11. In the present embodiment, a plurality of designated areas are defined in the site 11 as site areas, and any one of them is set as a warning area.

  FIG. 2 is a plan view of the site 11 showing a designated area in the security system. As shown in FIG. 2, in the site 11, a plurality of designated areas are defined in all areas except the building space of the building 10 according to the use of the site 11. In the present embodiment, six designated areas are provided, which are an approach area A, a delivery area B, a parking area C, a garden area D, a side passage area E, and a backyard area F, respectively. Among these, approach area A (hereinafter designated area A) is an area including approach 19 near entrance 19, and delivery area B (hereinafter designated area B) is approach area 18 near approach entrance 18, postbox 21 and delivery box. 22 and the parking area C (hereinafter designated area C) is an area including the parking space 14. The garden area D (hereinafter designated area D) is an area including the garden space 15, the side passage area E (hereinafter designated area E) is the area including the side passage space 16, and the backyard area F (hereinafter designated area). F) is an area including the backyard 17. Each of the designated areas A to F may be partially overlapped with each other, but is preferably determined so as not to overlap each other.

  In addition, the site 11 is provided with a plurality of human sensors 35 as human detection means including infrared sensors, and in the present embodiment, at least one human sensor 35 is disposed in each of the designated areas A to F. Each of the human sensors 35a to 35f has a designated area as a detection area. For example, the human sensor 35a arranged in the designated area A has the entire designated area A as a detection area and is arranged in the designated area B. The detected human sensor 35b has the entire designated area B as a detection area. That is, according to the human sensors 35a to 35f, the presence or absence of a person in each of the designated areas A to F is detected.

  On the other hand, outside the designated areas A to F, there is provided an operation panel unit 40 through which a person can input various information, and is arranged at the front entrance 18 in this embodiment. Thereby, various information can be input before the visitor enters the site 11.

  Next, the electrical configuration of the security system will be described with reference to FIG.

  In FIG. 3, the crime prevention system has a home server 30, which controls the entire system. The home server 30 is an arithmetic device provided with a known microcomputer or the like, and is installed on the wall surface of the building 10 such as a dining room. In addition to the human sensor 35 and the operation panel unit 40 described above, the home server 30 is connected to a display panel unit 50 installed indoors in the building 10 and an alarm device 55 for performing a warning. A security system is constructed by each device and the home server 30. Each of these configurations will be described below.

  The human sensor 35 (35a to 35f) sequentially outputs a human detection signal indicating the presence or absence of a person in each of the designated areas A to F to the home server 30. In addition, the operation panel unit 40 outputs various information input to the panel unit 40 to the home server 30. The operation panel unit 40 includes a communication unit 41 having a predetermined area around the front doorway as a communication range, and a display unit 42 such as a liquid crystal display.

  The communication unit 41 can wirelessly communicate with an electronic key 43 that is carried by a resident and in which unique identification information (ID information) is stored, and receives information (key ID) received from the electronic key 43 as a home. Output to the server 30. The home server 30 performs user authentication based on the key ID. If the key ID is a regular ID, it is determined that the visitor is a resident.

  In the present embodiment, the display unit 42 is configured as a touch panel, and includes a message field 44 for displaying a message and a plurality of touch buttons 45 as shown in FIG. In the message column 44, a message that prompts the visitor to operate the touch button 45 is displayed when there is a command signal from the home server 30 or at all times. The touch button 45 outputs information associated with the button to the home server 30 when the operator (visitor) performs a touch operation.

  A specific configuration of the touch button 45 is shown in FIG. In this embodiment, as the touch button 45, a doorbell button 46 for calling a resident is provided as shown in FIG. Here, in particular, there is provided a message selection button 47 that allows the operator to select a message for visiting.

  A plurality of requirement selection buttons 47 are provided, and a visitor type is displayed on each of these buttons. In this embodiment, as shown in FIG. 4, there are six buttons of “Neighborhood”, “Home Helper”, “Postal / Newspaper”, “Parcel Delivery”, “Meter Meter Reading”, and “Sales”. . For example, in the message field 44, “Please press the business button and then press the doorbell” is displayed. When the visitor touches the button of “Neighborhood” and presses the doorbell button 46 according to the message, for example. The visitor information indicating that the operator (visitor) is a neighbor is input to the home server 30.

  In addition, instead of writing the message selection button 47 as characters, for example, numeric code notation or cipher notation may be used. By using the numeric code notation or the like, it is possible to prevent the visitor information from being input by a person who does not know the relationship between the notation and the visitor type.

  Returning to the description of FIG. 3, the display panel unit 50 of the security system includes various information such as information received from the operation panel unit 40 (information on the visitor type) and visitor stay information (stay place, stay time, etc.). For example, disposed on the wall of a dining room. The alarm device 55 is a device that emits a warning sound such as a buzzer or warning light, and is arranged in the site 11. The alarm device 55 receives a drive signal from the home server 30 and issues a warning based on the drive signal.

  Next, the control of the home server 30 in this system will be described in detail below. In the above configuration, the home server 30 determines the visitor type based on the received information from the operation panel unit 40, and designates the designated areas A to F according to the visitor type and permits the visitor to enter. The distribution is made between SY and the non-permitted area SN that does not permit the visitor to enter. When a human detection signal indicating that there is a person is input from the human sensor 35 having the non-permitted area SN as a detection area, a warning is issued by outputting a drive signal to the alarm device 55.

  Specifically, the home server 30 includes a storage unit 31, a timer unit 32, and a control unit 33, as shown in FIG. The storage unit 31 stores various types of information related to the system such as a control program and a database. In particular, in this embodiment, the relationship between the visitor type and the permission area SY is stored in advance as a table, for example.

  FIG. 5 is a diagram illustrating an example of a control pattern indicating the relationship between the visitor type and the permission area SY. In the present embodiment, seven patterns are predetermined according to the visitor type. In FIG. 5, it is assumed that the resident is at home. In addition, the designated area other than the permitted area SY becomes the non-permitted area SN.

  As shown in FIG. 5, as visitor types, seven types are set: resident, neighbor (neighborhood), home helper, newspaper or postman, courier, meter meter, and salesman. Residents are included in visitors assuming that they are going home from home. The home helper refers to a person who is dispatched to an elderly person's home to provide physical care or housework assistance for the elderly person.

  Specifically, regarding the permission area SY, if the visitor is a resident, it is possible to enter any area in the site 11, so that the permitted area is the entire area (A, B, C, D) of the site 11. , E, F) (pattern 1). In addition, if it is a neighbor, it may be possible to enter the parking space 14 or the garden space 15 in addition to the entrance 19, so the permitted areas are A, B, C, and D (pattern 2). If it is a home helper, it may be possible to enter the entrance 19 or the parking space 14, so the permitted areas are A, B, and C (pattern 3).

  Further, in the case of a mail or newspaper delivery person, when the resident is at home, it is conceivable not only to put a mail item or the like into the mailbox 21 but also to deliver it directly to the resident at the entrance 19. Therefore, the permitted areas are A and B (pattern 4). Similarly, for the home delivery company, the permitted areas are A and B (pattern 5).

  When the visitor is a meter meter reader, the permitted areas are A, B, C, and E (pattern 6) in order to allow entry to the installation location of the meter facility 23 and the route to the installation location. In the case of a salesman, the permitted areas are A and B in consideration of entering the entrance 19 when the resident is at home (pattern 7).

  By the way, even when entering the permission area SY, the visitor stays in the permission area SY for an unreasonably long time for the business, or enters the time zone that does not meet the business, It can be said that this is suspicious behavior. Therefore, in the table of FIG. 5, in addition to the permitted area SY, the permitted time zone TA for entering the permitted area SY and the permitted time TB for staying in the permitted area are determined according to the visitor type. ing.

  In addition, permission time TB here means the accumulated time of the stay in all the permission areas SY instead of the stay time per one warning area.

  First, the permission time zone TA for entering the permitted area will be described. As shown in FIG. 5, in this embodiment, there are a standard time zone, a night time zone, and a sleeping time zone as time zone classifications, and visits to which time zone of these three time zones are allowed to enter are visited. It is set according to the person type. Here, for example, the standard time zone is defined as a time zone during which human activities become active (for example, 5:00 to 18:00). Is set to a time zone (for example, 18: 00 to 22:00) in which the person becomes a residence, and the sleeping time zone is set to a time zone (for example, 22: 00 to 5:00) when a person sleeps.

  Specifically, the allowable time zone TA is set to a standard time zone, a night time zone, and a sleeping time zone in order to allow a resident to enter the site 11 throughout the day (Pattern 1). On the other hand, for other visitors, it is not usually possible to enter the site 11 during the bedtime, so the entrance to the site 11 is not allowed during the bedtime, and neighbors, home helpers For delivery persons such as mail and delivery companies, the allowable time zone TA is the standard time zone and night time zone (patterns 2, 3, 4, and 5), and for meter readers and salesmen, the allowable time zone TA is the standard time zone. (Patterns 6 and 7).

  Moreover, about the permission time TB of the stay in a permission area, the permission time is shortened, so that the visitor with a high alert level. Specifically, in the case of a resident or a neighbor, since the alert level is relatively low, it is set to the longest time (for example, no time limit) within the time range that can be set as the permission time TB (Pattern 1, 2). In addition, in the case of a delivery person such as a home helper or a mail, a courier, or a meter meter, the warning level is not so high although it is lower than that of a resident or the like. , 5, 6). On the other hand, in the case of a salesman, since the alert level is relatively high, it is set to the shortest time (for example, 3 minutes) among visitor types (pattern 7).

  Returning to the description of the home server 30 in FIG. 3, the timer unit 32 is a timing device synchronized with the current time, and sequentially outputs time information regarding the current time to the control unit 33. In addition, when a human detection signal indicating that a person is present is input from any of the human sensors 35a to 35f to the home server 30, the timer unit 32 measures an elapsed time from the start of the input, and calculates the same measurement time. The data is sequentially output to the control unit 33.

  The control unit 33 executes various programs stored in the storage unit 31 based on various signals input from the operation panel unit 40, the human sensor 35, and the timer unit 32. Specifically, the control unit 33 includes visitor information from the item selection button 47 of the operation panel unit 40, a control signal from the doorbell button 46, a human detection signal from the human sensor 35, and a timer unit 32. While inputting time information, measurement time, etc., based on various input information, the drive signal which alerts the alarm device 55 is output. And the control part 33 memorize | stores the permission area SY, permission time slot | zone TA, and permission time TB corresponding to the visitor information in the memory | storage part 31, when the visitor information from the message selection button 47 is input. And set warnings according to the settings.

  Next, operation | movement of this crime prevention system performed by the control part 33 of the home server 30 is demonstrated using the flowchart of FIG. This process is executed at a predetermined time period.

  In FIG. 6, in step S <b> 10, it is first determined whether or not a permission area SY is set based on visitor determination. If the permission area SY is not set, it is determined that the visitor is not in the site 11 and the process proceeds to step S11. In step S <b> 11, the presence / absence of a visitor to the building 10 is determined based on information received from the operation panel unit 40. When the visitor information is input from the operation panel unit 40 or the key ID is received from the operation panel unit 40, it is determined that there is a visitor, and the process proceeds to step S12 to determine the visitor type. Here, based on the visitor information from the operation panel unit 40, it is determined whether the visitor corresponds to a neighbor, a home helper, a postal or newspaper delivery person, a courier, a meter reading person, or a salesman. . Further, user authentication is performed with the key ID from the communication unit 41 of the operation panel unit 40, and when the key ID is a regular ID, the visitor is determined to be a resident.

  In the subsequent step S13, the permission area SY, the permission time zone TA for entering the permission area SY and the permission time TB for staying in the permission area SY are set according to the visitor type. In the present embodiment, the control pattern corresponding to the visitor type is determined using the table of FIG.

  In step S <b> 14, it is determined whether or not the presence sensor is detected by the human sensor 35. If the presence sensor 35 does not detect the presence of a person, the process proceeds to step S15, and does not shift to a warning mode in which the site 11 is in a warning state, and the warning by the warning device 55 is not performed.

  On the other hand, if the presence sensor 35 detects the presence of a person, the process proceeds to step S16, and the presence of the person is detected in any of the designated areas A to F based on the person detection signals from the presence sensors 35a to 35f. It is determined whether or not the area is the permitted area SY. If the area where the presence of the person is detected is the permission area SY, the process proceeds to step S17, and the current time zone is any of the standard time zone, the night time zone, and the sleeping time zone according to the time information from the timer unit 32. And whether or not the current time zone is the permitted time zone TA is determined.

  If the current time zone is the permitted time zone TA, the process proceeds to step S18, the measurement time from the start of inputting the human detection signal indicating the presence of a person is input from the timer unit 32, and the measurement time is set to the permitted time TB. It is determined whether or not it exceeds. If the measurement time is within the permitted time TB, the process proceeds to step S15, the mode is not shifted to the warning mode, and the warning by the warning device 55 is not performed.

On the other hand, the following cases (1) to (3), that is,
(1) When the warning area detected as having a person by any of the presence sensors 35 is the non-permitted area SN (when a negative determination is made in step S16)
(2) The warning area detected as having a person is the permission area SY, but the current time zone is not the permission time zone TA (when a negative determination is made in step S17)
(3) The warning area detected as having a person is the permission area SY, but the stay time in the permission area SY exceeds the permission time TB (when a negative determination is made in step S18)
The process proceeds to step S19, shifts to a warning mode, and a warning is given by the warning device 55.

  Note that the release of the setting of the permitted area SY and the non-permitted area SN may be performed by the home server 30 when, for example, a release button is provided on the display panel unit 50 and the resident operates the release button after the visitor leaves. . The home server 30 may cancel the setting when the operation panel unit 40 is operated by the next visitor. Alternatively, the home server 30 may cancel the setting after a predetermined time has elapsed since the operation panel unit 40 was operated by the visitor.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  A visitor type is determined based on information received from the operation panel unit 40, and according to the visitor type, one of designated areas A to F is set as a warning area (non-permitted area SN). Since it is configured to issue a warning when a person detection signal indicating that there is a person is input from the human sensor 35 having the permission area SN as a detection area, a person other than the suspicious person is alerted to the intrusion of the suspicious person. Can prevent the security system from reacting excessively. Thereby, appropriate crime prevention can be implemented according to the visitor type.

  In addition, for a designated area (permitted area SY) other than the non-permitted area SN, a permitted time TB for staying in the permitted area SY is set according to a visitor type, and a permitted time TB in the permitted area SY is set. Since it is set as the structure which alerts when exceeding, it can prevent a visitor staying in permission area SY unreasonably long with respect to the requirement. Therefore, the suspicious person can be suitably excluded, and the crime prevention performance can be improved.

  Further, an allowable time zone TA for entering the permitted area SY is set according to the visitor type, and a warning is issued when it is detected that the vehicle has entered the permitted area SY in a time zone other than the permitted time zone TA. Due to the configuration, it is possible to prevent a visitor from entering the permitted area during a time zone that does not meet the requirements. Therefore, the suspicious person can be suitably excluded, and the crime prevention performance can be improved.

(Other embodiments)
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  In the above embodiment, the schedule information of the visitor may be stored in the storage unit 31 of the home server 30, and the home server 30 may perform a warning based on the visit schedule information. Specifically, the resident first registers the visit schedule information of the visitor in the storage unit 31 before the visitor visits. The visit schedule information includes the type of visitor, the visit date and the time. Further, it may be possible to input a permission area SY that permits entry, a stay permission time TB, and the like. Then, the home server 30 compares the visitor information input by the visitor from the operation panel unit 40 with the visit schedule information at that time, and if the visitor information and the visit schedule information match, The warning in the permission area SY is not performed in order to permit entry into the permission area SY determined based on the visitor information. On the other hand, if the information does not match, entry into the permitted area SY is not permitted, and when the visitor enters the site 11, the warning mode is entered and a warning is given. Thereby, it is possible to prevent spoofing of a legitimate visitor even though it is actually a visit with a different requirement from the visitor information (for example, a visit to enter the building 10).

  When setting the permission area SY, the permission time zone TA, and the permission time TB according to the visitor type, for example, the display panel unit 50 is provided with a mode switching unit that allows the resident to switch between the home mode and the absent mode, You may set permission area SY etc. according to the mode set in the mode switching part. In this case, for example, for the permission area SY, if it is a newspaper delivery person, a courier, or a salesman, it is not necessary to go to the entrance 19 if the call bell button 46 is pressed to confirm that the resident is absent. Therefore, in the home mode, the permitted areas are A and B, whereas in the absent mode, the permitted area may be only B.

  Further, the stay permission time TB may be set to different lengths in the home mode and the absent mode. At this time, if the visitor is not a resident, it is considered that he / she will leave the site 11 immediately after confirming the absence by pressing the doorbell button 46. Therefore, a visitor other than the resident is permitted in the absence mode rather than the home mode. You should shorten the time. For example, in the case of a courier or salesman such as a neighbor or a newspaper delivery person, the permission time in the absence mode is set to be shorter (for example, 3 minutes) than the permission time in the home mode.

  -When warning is implemented in the alert mode, the embodiment of warning may be changed according to the visitor type. For example, a warning level is determined according to the visitor type, and the threatening effect becomes higher as the warning level is higher. Specifically, since the alert level is relatively low for neighbors and home helpers, the threatening effect is relatively low for those persons. On the other hand, since the alert level is relatively high for a salesman, the threatening effect is relatively high for the person. This is suitable for excluding visitors with high vigilance from the site 11 while suppressing excessive warning to visitors with weak vigilance. Here, for example, the warning mode may be voice guidance indicating that the site is guarded in order from the least threatening effect, an intermittent sound “Pippi”, a continuous sound “Pee”, and the like.

  -When warning is executed under the warning mode, a warning level is set in advance for each of the designated areas A to F, and the warning is executed in a manner corresponding to the warning level in the designated area detected as having a person. It is good. At this time, it is desirable that the warning mode has a higher threatening effect as the warning level of the designated areas A to F is higher. For example, in the site 11, in the area including the window part and the entrance 19 of the building 10, in order to prevent a suspicious person from entering the building 10 from the window part or the like, the warning level is set relatively high, Implement warnings that are relatively intimidating. On the other hand, in an area including the garden space 15 (designated area D), a warning level is set to be relatively low in consideration of a malfunction caused by a small animal or the like, and a warning with a relatively low threat is implemented.

  -In the said embodiment, although it was set as the structure which sets the permission time TB of the stay in permission area SY according to a visitor type, this is changed and according to the present time or time slot | zone further in the same visitor type The permitted time TB may be changed. For example, the permission time TB is shortened in this order in the three time segments of the standard time zone, the night time zone, and the sleeping time zone. At this time, the embodiment of the warning may be changed according to the current time or the time zone.
