Description

  The present invention relates to a device for reporting the state of a monitored object to a center device or the like. For example, the monitored object is a facility in an elevator car or building, and the state or abnormality of the elevator car or facility in the building is reported to the center device or the like. Relates to the device.

For example, there is a device described in Patent Document 1 as a device for reporting the state of a monitoring object.
Patent Document 1 discloses a technique for transmitting failure information by e-mail to a mail address registered in advance by a reporting device when an abnormality occurs in a monitoring target device.
Japanese Patent Laid-Open No. 2007-4278

The notification device described in Patent Document 1 does not have a means for identifying and determining that it has been moved to another location.
For this reason, for example, when the reporting device is stolen and moved from the default installation position to another location, it is easy to analyze the program about the operational algorithm of the reporting device, the communication protocol with the center device, etc. There is.

  One of the main objects of the present invention is to solve the above-mentioned problems, and a program showing a procedure for detecting that a user has moved from the installation position to another place and making a report is shown. The main purpose is to realize a reporting device that performs measures that cannot be analyzed.

The reporting device according to the present invention is:
A reporting device that is installed at a predetermined location and reports the status of a monitoring object,
A program storage unit for storing a program for reporting the state of the monitored object;
An installation position storage unit for storing the installation position;
A positioning unit for positioning the location of the reporting device at a predetermined timing;
A position comparison unit that determines whether the location position measured by the positioning unit and the installation position stored in the installation position storage unit match within a predetermined range;
And a control unit configured to make the program stored in the program storage unit unreadable when the location position and the installation position do not match within a predetermined range.

  According to the present invention, the reporting device compares the measured location and the stored installation position, and if both do not match, the program for reporting is in a state where it cannot be read. Even if the reporting device is stolen, it is possible to avoid a situation in which the program is illegally analyzed.

Embodiment 1 FIG.
In the present embodiment and the following embodiments, the emergency notification device 1 for reporting the state of the monitored object to the center device or the like will be described. As an example, the emergency notification device 1 is installed in a building or a predetermined position of an elevator car, The emergency call device 1 that uses the equipment and the elevator car as the monitoring object will be described.
The emergency notification device 1 is an example of a notification device.

FIG. 1 shows a configuration example of an emergency call device 1 according to the present embodiment.
The control unit 2 controls each component in the emergency call device 1.
The installation position storage unit 3 stores an installation position where the emergency call device 1 is installed.
The program storage unit 4 stores a program for reporting the state of the monitored object. The program stored in the program storage unit 4 describes an operation algorithm of the emergency call device 1, a communication protocol with the center device, a procedure for making a report, and the like.
The positioning unit 5 receives, for example, a GPS (Global Positioning System) radio wave at a predetermined timing, and measures the location of the emergency call device 1.
The position comparison unit 6 determines whether the location position measured by the positioning unit 5 matches the installation position stored in the installation position storage unit 3.
Then, as a result of the comparison by the position comparison unit 6, the control unit 2 puts the program stored in the program storage unit 4 into a state where the program storage unit 4 cannot be read when the location position and the installation position do not match. For example, the control unit 2 erases the program so that it cannot be read.
The power management unit 8 manages the power supply (not shown) of the emergency call device 1. The power management unit 8 detects the power-on and notifies the control unit 2 of the power-on.

For example, the installation position storage unit 3 and the program storage unit 4 are realized by a rewritable nonvolatile memory.
Moreover, the control part 2, the positioning part 5, and the position comparison part 6 are implement | achieved by CPU (Central Processing Unit), for example.

  FIG. 1 shows a configuration for explaining the characteristics of the emergency call device 1 according to the present embodiment. For example, a communication means for reporting a state to the center device or the like, or a GPS signal is received. The description of a GPS receiver for the purpose is omitted.

Next, the operation of the emergency call device 1 according to the present embodiment will be described with reference to FIG.
When the emergency call device 1 is installed at a predetermined installation position (S201) and the power is turned on (S202), the power management unit 8 notifies the control unit 2 that the power is turned on. The positioning unit 5 measures the installation position (S203), and stores the position information of the installation position in the installation position storage unit 3 (S204).

Next, when the emergency call device 1 is turned off (S205) and turned on again (YES in S206), the power management unit 8 notifies the control unit 2 that the power is turned on, and follows the instructions of the control unit 2 The positioning unit 5 measures the location (S207).
Then, the position comparison unit 6 compares the location position measured by the positioning unit 5 in S207 with the installation position stored in the installation position storage unit 3 (S208), and the location position and the installation position completely match. In such a case, the emergency notification device 1 performs normal operation, monitors the monitored object, and reports the status to the center device or the like as necessary.
On the other hand, if the location and the installation position do not match in S208, the emergency notification device 1 has been illegally moved, so the control unit 2 erases the contents (program) of the program storage unit 4 ( S209).
After this, the emergency call device 1 stops functioning.

  As described above, according to the present embodiment, when the power supply is restarted, the position information at the time of installation is compared with the current position information, and the program memory is erased in the case of being different. However, there is an effect that it is not possible to easily analyze the program such as the operation of the device and the communication protocol with the center device.

  As described above, in the present embodiment, the emergency notification device that reports the state or abnormality of the building elevator or building equipment to the center device or the like, the location information received by the GPS receiver, and previously stored location information In the case where the result of the comparison is not exactly the same, the emergency notification device that erases the program memory storing the self-program and does not start the next time has been described.

Embodiment 2. FIG.
FIG. 3 shows a configuration example of the emergency call device 1 according to the present embodiment.

3, the control unit 2, the installation position storage unit 3, the program storage unit 4, the positioning unit 5, the position comparison unit 6, and the power management unit 8 are the same as those shown in FIG.
The allowable range storage unit 7 stores the allowable range of the difference between the location position and the installation position.
The allowable range setting unit 9 sets the allowable range of the difference between the location position and the installation position.

Next, the operation of the emergency call apparatus 1 according to the present embodiment will be described with reference to FIG.
In FIG. 4, the steps denoted by the same reference numerals as those in FIG. 2 are the same as those in FIG. 2.
First, when the emergency call device 1 is installed at a predetermined installation position (S201) and the power is turned on (S202), the power management unit 8 notifies the control unit 2 that the power is turned on. Accordingly, the positioning unit 5 measures the installation position (S203).
Further, the allowable range setting unit 9 sets the allowable range of the difference between the location and the installation position in the allowable range storage unit 7 (S401). In the present embodiment, for example, a case where a radius of 5 m is set in the allowable range storage unit 7 will be described.
Next, the position information of the installation position measured by the positioning unit 5 is stored in the installation position storage unit 3 (S204).

Next, when the emergency call device 1 is turned off (S205) and turned on again (YES in S206), the power management unit 8 notifies the control unit 2 that the power is turned on, and follows the instructions of the control unit 2 The positioning unit 5 measures the location (S207).
Next, the position comparison unit 6 determines the allowable range (radius 5 m) stored in the allowable range storage unit 7 in S401 to the location position measured by the positioning unit 5 in S207 and the installation position stored in the installation position storage unit 3. ) Is compared (S402).
If the location position and the installation position match within the allowable range, that is, if the location position is within a radius of 5 m from the installation position, the emergency call device 1 performs normal operation and monitors the monitoring target. Depending on the situation, the status is reported to the center device.
On the other hand, if the location position and the installation position do not match within the allowable range in S402, that is, if the location position is at a radius of 5 m or more from the installation position, the emergency call device 1 is illegally moved. Since it is in the state, the control unit 2 erases the contents (program) of the program storage unit 4 (S209).
After this, the emergency call device 1 stops functioning.

While the comparison range in the first embodiment is “one point match”, in the present embodiment, a matching area is set so that the position information has a certain comparison range.
As a result, even if the emergency call device is intentionally moved, such as during maintenance, if it moves within a certain area, it is not determined that it has moved, and the contents of the program memory may be erased by mistake. Absent.

Embodiment 3 FIG.
In the second embodiment, by setting an allowable error range, the emergency call device can be moved within a certain range at the time of maintenance or the like, but it is assumed that the set range initially set during operation is exceeded. May be.
In the present embodiment, in response to such a case, the allowable range can be temporarily changed to an arbitrary radius as necessary, thereby enabling more flexible operation.

For example, as shown in FIG. 5, when an emergency call device (1) is installed, if a radius of 5 m is set as an allowable range of difference by the allowable range setting unit 9 (S501 to S504), the renovation work in the building・ When it is necessary to move the emergency call device 1 to a position 5 m or more away from the original position due to a layout change, the allowable range setting section 9 The allowable range is temporarily changed to a size (for example, a radius of 10 m) necessary for moving the emergency call device 1 (S505).
As a result, after the power is turned off (S506), when the emergency call device 1 is moved to a position 5 m or more away from the original position (S507) and the power is turned on (S508), the temporarily set allowable range (radius 10m), the position comparison unit 6 determines that they match (S509), and can prevent the contents of the program from being inadvertently deleted.
Further, when the set value of the allowable range storage unit 7 is temporarily increased by such relocation, the operator normally sets the changed set value of the allowable range storage unit 7 after the work is completed. It returns to the value (radius 5 m) (S511).

As described above, in the present embodiment, when the emergency call device is moved beyond the predetermined setting area due to renovation work or layout change in the building, an arbitrary comparison range larger than this setting area is temporarily set. I can do it.
As a result, even if it moves beyond the preset setting area, if it is within the temporary setting area, it is not determined that it has moved, and the contents of the program memory can be prevented from being inadvertently erased. .

  As described above, in the present embodiment, the coincidence range setting memory is mounted, the position information is received by the GPS receiver, and the result of comparison with the previously stored position information exceeds the range set in the coincidence range setting memory. We explained an emergency call device that erases the program memory that stores its own program and prevents it from being activated next time when the location information changes.

Embodiment 4 FIG.
Next, an operation example of the emergency call device according to the fourth embodiment will be described with reference to FIGS.

  In the third embodiment, the permissible range of the permissible range storage unit 7 is restored by human means (operator). However, in the fourth embodiment, the permissible range setting unit 9 sets the initial setting of the permissible range storage unit 7. The value is registered as a default value, and when it starts normally after movement, the allowable range setting unit 9 automatically returns it to the default value.

That is, in S601 of FIG. 6, the allowable range setting unit 9 sets the allowable range of difference in the allowable range storage unit 7, and registers the value as a default value.
If the location of the emergency call device 1 after the relocation is within the temporarily set allowable range (radius 10 m), the position comparison unit 6 determines that they match (S509), and the allowable range setting unit 9 stores the allowable range. The allowable range of part 7 is automatically returned to the default value (S602).
In FIG. 6, the steps denoted by the same reference numerals as those in FIG. 5 are processed in the same manner as in FIG.

In operation, the third embodiment and the fourth embodiment are selectively used according to the purpose.
For example, the fourth embodiment is set to the “AUTO” mode that is normally used, and the third embodiment is set to the “MANUAL” mode.
In “AUTO” mode, the emergency call device (1) is moved from the original position to a predetermined value or more (in the third embodiment, the radius is between 5 m and 10 m), is normally activated, and is turned off. Used when returning to (removal once).
On the other hand, in the “MANUAL” mode, the emergency call device (1) is moved from the original position to a predetermined value or more (in the third embodiment, between a radius of 5 m and 10 m), is normally started, and the power is turned off. It does not return to the position of, but is used when it is moved again within a predetermined range (moving is performed a plurality of times).

  In the second to fourth embodiments, the allowable range storage unit (7) is set when a changeable range of position information (for example, a radius of 5 m) is set in the allowable range storage unit (7) or according to the purpose. To temporarily set the changeable range of position information to an arbitrary radius (for example, between 5 m and 10 m), connect the maintenance computer (maintenance computer) owned by the elevator maintenance company to the emergency call device (1). Then, the maintenance staff of the maintenance company sets the allowable range setting unit 9 according to the setting instruction.

  As described above, in the present embodiment, a match range is set in the match range setting memory, the position information is received by the GPS receiver, and the result of comparison with the previously stored position information is within the range set in the match range setting memory. In such a case, it is possible to eliminate a human error due to forgetting to return the matching range setting memory by automatically returning the value of the matching range setting memory after normal startup.
