Disclosure of Invention
[ problem to be solved by the invention ]
In the case of constructing a monitoring system in which a plurality of devices are connected via a network, if there is a functional difference in the functions of the plurality of devices connected together, the monitoring system must have a structure that absorbs the functional difference between the devices as needed.
Therefore, conventionally, for example, when a device with poor functions is connected to a lower level of a network, a higher-level device (hereinafter referred to as a "higher-level device") connected to the lower-level device (hereinafter referred to as a "lower-level device") performs the functions of the lower-level device instead.
As described above, when devices of a plurality of different manufacturers are connected, the probability of functional differences between the functions held in the devices increases, and the necessity of providing a structure for absorbing the functional differences increases.
Whether the device implementing the monitoring function for each monitoring point is an upper-level device or a lower-level device is preferably managed in advance for each management object by a manager or the like.
Therefore, for example, when the monitoring function to be executed is changed after the monitoring system starts operating, and the upper apparatus and the lower apparatus switch the apparatus to which the monitoring function after the change is executed, the administrator or the like needs to perform the management again each time, which causes a problem that the monitoring system must be suspended.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the drawings.
Embodiment 1.
Fig. 1 is a diagram showing an example of the configuration of a monitoring system according to embodiment 1.
The monitoring system according to embodiment 1 is applied to, for example, a building monitoring system, a plant monitoring system, or the like. The monitoring system uses, for example, BACnet (Building Automation and Control network protocol) as a communication network.
As shown in fig. 1, the monitoring system includes a monitoring device 1, an upper device 2, a lower device 3, and the like.
The monitoring device 1 and the host device 2 are connected via a network.
The upper device 2 is connected to the lower device 3 via a lower network.
The lower-level apparatus 3 is connected to 1 or more control devices (not shown) via a lower-level network. The control device refers to a sensor, a light, a switch, a motor, and the like, and is installed in a facility.
The monitoring apparatus 1 displays information related to equipment in a facility or control equipment installed in the facility on a display device (not shown) such as a display, and a manager or the like monitors or controls the equipment in the facility or the control equipment installed in the facility by checking the display device.
The monitoring apparatus 1 monitors or controls equipment in a facility, control equipment in the facility, and the like via the higher-level apparatus 2 and the lower-level apparatus 3.
The monitoring operation or the control operation of the monitoring apparatus 1 is executed by a program process using a CPU based on software.
Hereinafter, a device in a facility to be monitored by the monitoring apparatus 1, a control device provided in the facility, or the like is referred to as a monitoring point.
The host device 2 monitors or controls the host device 3 connected via the host network according to the control of the monitoring device 1. The upper apparatus 2 monitors or controls a plurality of control devices connected to the lower apparatus 3 via the lower network.
The monitoring operation or the control operation of the host device 2 is executed by a program process using a CPU based on software.
The lower apparatus 3 monitors or controls a plurality of control devices connected via the lower network in accordance with the control of the upper apparatus 2.
The monitoring operation or the control operation of the lower apparatus 3 is executed by a program process using a CPU based on software.
In fig. 1, 1 upper device 2 and 2 lower devices 3 are connected to the network, but this is merely an example, and 1 or more upper devices 2 and 1 or more lower devices 3 are connected to the network.
Fig. 2 is a block diagram showing an example of the configuration of the monitoring device 1 according to embodiment 1.
The monitoring device 1 includes a switching instruction receiving unit 11, a switching instruction transmitting unit 12, and a display control unit 13.
The switching instruction receiving unit 11 receives an instruction to switch the monitoring function for a target monitoring point (described later) among 1 or more monitoring points. In embodiment 1, the monitoring function is a function for monitoring each monitoring point, and the monitoring device 1 monitors each monitoring point based on information on each monitoring point acquired by the upper apparatus 2 or the lower apparatus 3 performing the monitoring function.
What kind of monitoring function is performed on each monitoring point is set in advance by a manager or the like in accordance with monitoring contents and a management device (not shown in fig. 1) at the time of construction of the monitoring system.
Then, when the monitoring system starts to operate and wants to switch the monitoring function intended to be performed at the corresponding monitoring point, the manager or the like inputs an instruction to switch the monitoring function at the corresponding monitoring point from the monitoring apparatus 1. Specifically, the administrator or the like operates an input device (not shown) such as a mouse or a keyboard to input an instruction to switch the monitoring function to the corresponding monitoring point.
In embodiment 1, the monitoring point to which the monitoring function is switched is referred to as an object monitoring point.
The switching instruction receiving unit 11 receives a switching instruction input by an administrator or the like.
The switching instruction receiving unit 11 outputs information on the received switching instruction to the switching instruction transmitting unit 12.
The switching instruction transmitting unit 12 transmits information relating to the switching instruction output from the switching instruction receiving unit 11 to the host device 2.
The display control unit 13 displays various information on a display device (not shown).
The display device may be provided in the monitoring device 1, or may be provided outside the monitoring device 1.
Fig. 3 is a block diagram showing an example of the configuration of the higher-level device 2 according to embodiment 1.
The upper device 2 includes a switching instruction receiving unit 21, a function determining unit 22, a table storage unit 23, an upper monitoring control unit 24, a lower control instruction creating unit 25, and a lower control instruction transmitting unit 26.
The upper monitoring control unit 24 includes an upper validation control unit 241 and an upper invalidation control unit 242. The lower control instruction creation unit 25 includes a lower valid instruction creation unit 251 and a lower invalid instruction creation unit 252.
The switching instruction receiving unit 21 receives information relating to the switching instruction transmitted from the switching instruction transmitting unit 12 of the monitoring apparatus 1.
The switching instruction receiving unit 21 outputs the received information on the switching instruction to the function determining unit 22.
The function determination unit 22 determines which of the upper apparatus 2 and the lower apparatus 3 performs the monitoring function after switching with respect to the target monitoring point indicated by the switching instruction, based on the information on the switching instruction output from the switching instruction receiving unit 21 and the function switching information (to be described later) defined in the function switching table stored in the table storage unit 23 (to be described later).
The function determination unit 22 outputs information on the determination result of the monitoring function performed by either the upper-level device 2 or the lower-level device 3 as to the monitoring function after switching of the target monitoring point to the upper-level monitoring control unit 24 and the lower-level control instruction creation unit 25.
The table storage unit 23 stores a function switching table.
Here, fig. 4 is a diagram for explaining an example of the function switching table stored in the table storage unit 23 in embodiment 1.
The function switching table defines function switching information indicating a correspondence relationship between monitoring functions performed by the higher-level device 2 and the lower-level device 3. The function switching information is defined in advance by an administrator or the like. The function switching information is set for each monitoring point.
For example, in fig. 4, the monitoring point a can be switched between "deviation monitoring" and "upper and lower limit monitoring", and in the case of "deviation monitoring", the upper-level device 2 performs the "deviation monitoring", and in the case of "upper and lower limit monitoring", the lower-level device 3 performs the "upper and lower limit monitoring", and the function switching table defines the function switching information indicating the correspondence relationship.
In embodiment 1, as shown in fig. 3, the table storage unit 23 is provided in the host device 2, but the present invention is not limited to this, and the table storage unit 23 may be provided outside the host device 2 at a location where the host device 2 can refer to.
The upper monitor control unit 24 activates or deactivates the monitoring function in the upper device 2 based on the determination result of the function determination unit 22 determining whether the monitoring function after switching indicated in the switching instruction is the monitoring function executed by either the upper device 2 or the lower device 3.
When the function determination unit 22 determines that the switched monitoring function instructed by the switching instruction is the monitoring function implemented by the higher-level device 2, the higher-level activation control unit 241 of the higher-level monitoring control unit 24 activates the switched monitoring function for the target monitoring point in the higher-level device 2.
When the function determination unit 22 determines that the monitoring function after switching instructed by the switching instruction is the monitoring function to be implemented by the lower apparatus 3, the upper invalidation control unit 242 of the upper monitoring control unit 24 invalidates the monitoring function to the target monitoring point being implemented by the upper apparatus 2.
The lower control instruction creating unit 25 creates lower valid instruction information for making the monitoring function in the lower device 3 valid or lower invalid instruction information for making the monitoring function in the lower device 3 invalid, based on the determination result of the function determining unit 22 determining which of the upper device 2 and the lower device 3 performs the monitoring function after the switching indicated by the switching instruction.
When the function determination unit 22 determines that the switched monitoring function indicated in the switching instruction is the monitoring function implemented by the lower-level device 3, the lower-level valid instruction creation unit 251 of the lower-level control instruction creation unit 25 creates, for the lower-level device 3, lower-level valid instruction information for making the switched monitoring function for the target monitoring point valid. The lower significant instruction generator 251 outputs the generated lower significant instruction information to the lower control instruction transmitter 26.
When the function determination unit 22 determines that the switched monitoring function instructed by the switching instruction is the monitoring function to be executed by the upper device 2, the lower invalidation instruction creating unit 252 of the lower control instruction creating unit 25 creates, for the lower device 3, lower invalidation instruction information for invalidating the monitoring function being executed for the target monitoring point. The lower invalid instruction generating unit 252 outputs the generated lower invalid instruction information to the lower control instruction transmitting unit 26.
The lower control instruction transmitting unit 26 transmits the lower valid instruction information or the lower invalid instruction information output from the lower control instruction generating unit 25 to the lower device 3.
In the higher-level device 2, the function determination unit 22 determines whether the monitoring function after switching to the target monitoring point indicated by the switching instruction is the monitoring function performed by either the higher-level device 2 or the lower-level device 3, and controls the monitoring function to the target monitoring point so that only either the higher-level device 2 or the lower-level device 3 is effective.
Therefore, when the function determination unit 22 determines that the switched monitoring function instructed by the switching instruction is the monitoring function implemented by the upper device 2, for example, the lower invalidation instruction creating unit 252 creates lower invalidation instruction information for invalidating the monitoring function being implemented to the lower device 3, and the lower control instruction transmitting unit 26 transmits the lower invalidation instruction information to the lower device 3 according to the control of the function determination unit 22, so that the corresponding monitoring function that is valid in the lower device 3 is invalidated, and then the upper validation control unit 241 validates the switched monitoring function for the target monitoring point in the upper device 2. The structure and the like of the lower apparatus 3 will be described later.
When the function determination unit 22 determines that the switched monitoring function instructed by the switching instruction is the monitoring function implemented by the lower apparatus 3, for example, the upper invalidation control unit 242 invalidates the monitoring function for the target monitoring point that is valid in the upper apparatus 2 according to the control of the function determination unit 22, and then the lower valid instruction creation unit 251 creates lower valid instruction information for validating the switched monitoring function for the target monitoring point in the lower apparatus 3, and the lower control instruction transmission unit 26 transmits the lower valid instruction information to the lower apparatus 3, thereby validating the corresponding monitoring function in the lower apparatus 3.
The function determination unit 22 may be configured to generate the lower invalidation instruction information by the lower invalidation instruction generation unit 252, transmit the lower invalidation instruction information to the lower device 3 by the lower control instruction transmission unit 26, and enable the monitoring function after switching with respect to the target monitoring point by the upper device 2 by the upper validation control unit 241.
The function determination unit 22 may be configured to generate the lower valid instruction information by the lower valid instruction generation unit 251 and to transmit the lower valid instruction information to the lower device 3 by the lower control instruction transmission unit 26, while the upper invalidation control unit 242 invalidates the monitoring function that is valid in the upper device 2.
The function determination unit 22 may control the upper monitor control unit 24 and the lower control instruction creation unit 25 so as not to bring the monitoring function into a state in which both the upper device 2 and the lower device 3 are simultaneously enabled.
The details of the operation will be described later.
Fig. 5 is a block diagram showing an example of the configuration of the lower apparatus 3 according to embodiment 1.
The lower-level device 3 includes a lower-level control instruction receiving unit 31 and a lower-level monitoring control unit 32.
The lower control instruction receiving unit 31 receives the lower valid instruction information or the lower invalid instruction information transmitted from the lower control instruction transmitting unit 26 of the upper device 2.
The lower control instruction receiving unit 31 outputs the received lower valid instruction information or lower invalid instruction information to the lower monitoring control unit 32.
The lower monitoring control unit 32 enables or disables the monitoring function for the target monitoring point by the lower device 3 based on the lower validity instruction information or the lower invalidity instruction information output from the lower control instruction receiving unit 31.
Specifically, when the lower significant instruction information is acquired, the lower monitoring control unit 32 enables the monitoring function based on the lower significant instruction information for the target monitoring point in the lower device 3.
On the other hand, when the lower invalid instruction information is acquired, the lower monitoring control unit 32 invalidates the monitoring function that is being performed on the target monitoring point in the lower device 3.
Next, the operation of the monitoring system according to embodiment 1 will be described.
As a premise, in the monitoring system, when the monitoring system is constructed in advance, the monitoring function for each monitoring point and the device (the higher-level device 2 or the lower-level device 3) that implements the monitoring function are managed by a management device connected to the network, and the higher-level device 2 or the lower-level device 3 implements the monitoring function in accordance with the managed contents.
For example, in embodiment 1, in the monitoring system, either the "upper and lower limit monitoring" or the "deviation monitoring" function can be performed for the monitoring point a, and when the monitoring system is constructed, the administrator or the like sets the "upper and lower limit monitoring" to be performed and starts the operation. The administrator or the like sets that the lower apparatus 3 performs "upper and lower limit monitoring". In this case, the administrator or the like manages the upper apparatus 2 so as to disable the implementation of the monitoring function for the monitoring point a.
In the following operation description, the operation of the monitoring system in the case where the switching of the monitoring function occurs after the construction of the monitoring system and the start of the operation as described above will be described. As an example, a case where switching of the monitoring function to the monitoring point a occurs will be described.
In the following description, the table storage unit 23 stores a function switching table as shown in fig. 4.
Fig. 6 is a flowchart illustrating an example of operations of the monitoring device 1, the higher-level device 2, and the lower-level device 3 in the monitoring system according to embodiment 1.
The switching instruction receiving unit 11 of the monitoring device 1 waits until it receives an instruction to switch the monitoring function to the target monitoring site (in the case of no at step ST 601), and when the switching instruction receiving unit 11 receives an instruction to switch the monitoring function to the target monitoring site, it outputs the received information on the switching instruction to the switching instruction transmitting unit 12 of the monitoring device 1 (in the case of yes at step ST 601).
For example, when the current lower-level device 3 performs "upper and lower limit monitoring" for the monitoring point a and switches the monitoring function to the monitoring point a, the administrator or the like operates the input device and inputs a switching instruction to switch to "deviation monitoring" for the monitoring point a. Specifically, for example, the administrator or the like operates the input device to input the switching instruction input screen display instruction, and the display control unit 13 of the monitoring apparatus 1 causes the display device to display the switching instruction input screen. Then, the manager or the like inputs information of "monitoring point a" as the target monitoring point and information of "deviation monitoring" as the monitoring function after switching from the switching instruction input screen.
The switching instruction receiving unit 11 receives input of information on a target monitoring point (monitoring point a) and information on a monitoring function (deviation monitoring) after switching, and outputs the information to the switching instruction transmitting unit 12 as information on a switching instruction.
The display control unit 13 may display an input unit for inputting information of setting items required for the instructed monitoring function on the switching instruction input screen. The manager or the like inputs information of setting items and the like as necessary, and the switching instruction receiving unit 11 receives the information of the setting items and the like together and outputs the information to the switching instruction transmitting unit 12 as information related to the switching instruction.
The switching instruction transmitting unit 12 transmits the information on the switching instruction output from the switching instruction receiving unit 11 in step ST601 to the host device 2 (step ST 602).
The switching instruction receiving unit 21 of the higher-level device 2 receives the information related to the switching instruction transmitted from the switching instruction transmitting unit 12 of the monitoring device 1 in step ST602 (step ST 603).
The switching instruction receiving unit 21 outputs the received information on the switching instruction to the function determining unit 22 of the higher-order device 2.
The function determination unit 22 determines whether the monitoring function after the switching indicated by the switching instruction is the monitoring function to be performed by either the higher-level device 2 or the lower-level device 3, based on the information on the switching instruction output from the switching instruction receiving unit 21 in step ST603 and the function switching table (see fig. 4) stored in the table storage unit 23 (step ST 604).
The function determination unit 22 outputs information on the determination result of the monitoring function to the upper monitor control unit 24 and the lower control instruction creation unit 25 of the upper device 2.
Here, as the information on the switching instruction, information indicating that the "monitoring point a" is switched to the "deviation monitoring" is received, and therefore the function determination unit 22 determines that the "deviation monitoring" is the monitoring function performed by the host device 2.
Then, the function determination unit 22 outputs information indicating that the device performing the monitoring function "deviation monitoring" after the switching is the upper device 2 to the upper monitoring control unit 24 and the lower control instruction creation unit 25 as information related to the determination result of the monitoring function.
Based on the information on the determination result of the monitoring function output from the function determination unit 22 in step ST604, when the monitoring function after the switching is the monitoring function to be performed by the upper device 2 (in the case of yes in step ST 605), the lower invalidation instruction creating unit 252 of the lower control instruction creating unit 25 creates lower invalidation instruction information for invalidating the monitoring function being performed on the target monitoring point in the lower device 3 (step ST 606). Then, the lower invalidation instruction creating unit 252 outputs the created lower invalidation instruction information to the lower control instruction transmitting unit 26, and the lower control instruction transmitting unit 26 transmits the lower invalidation instruction information to the lower device 3. Further, the lower control instruction transmitting unit 26 transmits the lower invalidation instruction information to the lower device 3 that is monitoring the target monitoring point.
The lower control instruction receiving unit 31 of the lower device 3 receives the lower invalidation instruction information transmitted from the lower control instruction transmitting unit 26 of the upper device 2, and the lower monitoring control unit 32 of the lower device 3 invalidates the monitoring function currently being performed on the target monitoring point in the lower device 3 based on the lower invalidation instruction information received by the lower control instruction receiving unit 31.
The upper effective control unit 241 of the upper monitoring control unit 24 also enables the monitoring function after the switching to the target monitoring point in the upper device 2 (step ST 607).
Information on which upper apparatus 2 or lower apparatus 3 is monitoring each monitoring point is stored in advance in a place where the upper apparatus 2 can refer to. The lower control instruction transmitting unit 26 may determine the lower device 3 that transmits the lower invalidation instruction information based on the pre-stored information.
Here, since the function determination unit 22 determines that the device that performs the monitoring function "deviation monitoring" after the switching is the upper device 2, the lower invalidation instruction creating unit 252 creates the lower invalidation instruction information for invalidating the "upper and lower limit monitoring" currently performed on the monitoring point a to the lower device 3. The upper level active control unit 241 enables the "deviation monitoring" for the monitoring point a in the upper level device 2.
On the other hand, based on the information on the determination result of the monitoring function output from the function determination unit 22 in step ST604, when the monitoring function after the switching is the monitoring function to be performed by the lower apparatus 3 (in the case of no in step ST 605), the upper invalidation control unit 242 of the upper monitoring control unit 24 invalidates the monitoring function currently being performed on the target monitoring point in the upper apparatus 2 (step ST 608).
The lower significant instruction making unit 251 of the lower control instruction making unit 25 makes the lower device 3 lower significant instruction information for enabling the monitoring function after switching to the target monitoring point (step ST 609). Then, the lower significant instruction generator 251 outputs the generated lower significant instruction information to the lower control instruction transmitter 26, and the lower control instruction transmitter 26 transmits the lower significant instruction information to the lower device 3. Further, the lower control instruction transmitting unit 26 transmits the lower effective instruction information to the lower device 3 that is monitoring the target monitoring point. Information on which upper apparatus 2 or lower apparatus 3 is monitoring each monitoring point is stored in advance in a place where the upper apparatus 2 can refer to. The lower control instruction transmitting unit 26 may determine the lower device 3 that transmits the lower valid instruction information, based on the information stored in advance.
The lower control instruction receiving unit 31 of the lower device 3 receives the lower effective instruction information transmitted from the lower control instruction transmitting unit 26 of the upper device 2, and the lower monitoring control unit 32 of the lower device 3 enables the monitoring function after switching to the target monitoring point in the lower device 3 based on the lower effective instruction information received by the lower control instruction receiving unit 31.
By operating as described above, the monitoring function performed by the higher-level device 2 or the lower-level device 3 is automatically switched to the target monitoring site.
Since the monitoring device 1 receives an instruction to switch the monitoring function and the higher-level device 2 determines whether the monitoring function after the switching is performed by the higher-level device 2 or the lower-level device 3, the administrator or the like only needs to specify the target monitoring point and the monitoring function after the switching, and thus it is not necessary to actually recognize whether the monitoring function after the switching is performed by the higher-level device 2 or the lower-level device 3 at the time of the switching.
Further, since the switching of the monitoring function is automatically performed in the monitoring system in response to a switching instruction from the administrator or the like, the administrator or the like can perform the switching of the monitoring function without suspending the monitoring system after the start of the operation in order to perform the switching operation of the monitoring function.
Further, at the time of switching the monitoring function, the monitoring function that is being executed at the target monitoring point is invalidated in the higher-level device 2 or the lower-level device 3 that does not execute the monitoring function after the switching. Thus, the unnecessary monitoring function is automatically disabled without requiring a manager or the like to perform control for stopping the unnecessary monitoring function every time, and a state in which the monitoring function is doubly performed between the upper apparatus 2 and the lower apparatus 3 can be prevented. For example, if different monitoring functions are performed in duplicate between the upper apparatus 2 and the lower apparatus 3, an alarm or the like may be generated in duplicate when a situation occurs, and the monitoring or control of the monitoring point may not be performed normally. In the monitoring system according to embodiment 1, even if an administrator or the like does not perform any control, it is possible to prevent such a problem that the monitoring or control of the monitoring point cannot be normally performed because different monitoring functions are doubly performed.
In the above description, the monitoring system can perform any one of the "upper and lower limit monitoring" and the "deviation monitoring" on the monitoring point a, but this is merely an example, and the above operation can be applied to any monitoring function that can be performed on each monitoring point so as to be switchable. For example, in the monitoring system, the above operation can be applied even when any one of the "high-speed upper and lower limit monitoring function" and the "standard upper and lower limit monitoring function" is applied to the target monitoring point. The difference between the "high-speed upper and lower limit monitoring function" and the "standard upper and lower limit monitoring function" is a monitoring period.
For example, there are cases where: the upper device 2 has a high-specification CPU, the upper device 2 can perform the monitoring function in a 1-second cycle, and the lower device 3 has a lower specification than the upper device 2 and can perform the monitoring function only in a 30-second cycle. In this case, the two monitoring functions can be switched as follows: in the object monitoring site, the upper apparatus 2 performs the "high-speed upper and lower limit monitoring function" when it is desired to quickly detect the occurrence of an alarm or the like, and the lower apparatus 3 performs the "standard upper and lower limit monitoring function" when it is not necessary to quickly detect the occurrence of an alarm or the like.
In the above description, for example, when switching the monitoring function, the administrator or the like designates a target monitoring point, and the host device 2 performs switching control of the monitoring function in units of monitoring points.
However, this is merely an example, and the upper apparatus 2 may perform switching control of the monitoring function in units of apparatuses (the upper apparatus 2 or the lower apparatus 3) or in units of functions.
For example, when switching control of the monitoring function is performed on a device-by-device basis, a manager or the like inputs information of the device to be switched and information of the monitoring function after switching from a switching instruction input screen displayed on the monitoring device 1.
In this case, in the function switching table stored in the table storage unit 23 of the higher-level device 2, function switching information in which the device is associated with a monitoring point belonging to the device is defined as shown in fig. 7.
The switching instruction receiving unit 21 of the upper apparatus 2 receives information on the switching instruction transmitted from the monitoring apparatus 1, and the function determining unit 22 determines, based on the information for switching functions as shown in fig. 7, which of the upper apparatus 2 and the lower apparatus 3 is to perform the monitoring function after switching for each target monitoring point, with the monitoring point belonging to the apparatus to be the target indicated by the switching instruction as the target monitoring point.
Then, the upper monitor control unit 24 and the lower control instruction creation unit 25 enable or disable the monitoring function in the upper device 2 and the lower device 3, respectively. The specific operation of the switching control of the monitoring function in the host device 2 is the same as described above, and therefore, redundant description is omitted.
For example, the function switching table defines information for switching functions as shown in fig. 7, and when a switching instruction for switching the lower apparatus a to the upper and lower limit 3-stage monitoring is input from the monitoring apparatus 1 by a manager or the like, the monitoring functions of the upper apparatus 2 and the lower apparatus 3 are controlled so that the upper and lower limit 3-stage monitoring becomes effective for the monitoring points a and B in the upper apparatus 2.
For example, when switching control of the monitoring function is performed on a function basis, the manager or the like inputs information of the monitoring function after switching from the switching instruction input screen displayed on the monitoring apparatus 1.
In this case, the function switching information is defined as shown in fig. 8 in the function switching table stored in the table storage unit 23 of the higher-level device 2, and the function switching information is obtained by associating the device, the monitoring site belonging to the device, and information indicating which device is performing which monitoring function for each monitoring site. In fig. 8, the function given with "o" is the monitoring function being executed.
The switching instruction receiving unit 21 of the upper apparatus 2 receives information on the switching instruction transmitted from the monitoring apparatus 1, and the function determining unit 22 determines, based on the information for switching functions as shown in fig. 8, which of the upper apparatus 2 and the lower apparatus 3 is to perform the monitoring function to which the switched monitoring function for each target monitoring point is to be applied, by using, as the target monitoring point, the monitoring point for which the switched monitoring function indicated in the switching instruction is not valid.
Then, the upper monitor control unit 24 and the lower control instruction creation unit 25 enable or disable the monitoring function in the upper device 2 and the lower device 3, respectively. The specific operation of the switching control of the monitoring function in the host device 2 is the same as described above, and therefore, redundant description is omitted.
For example, the function switching table defines information for switching functions as shown in fig. 8, and when a switching instruction for switching to the offset monitoring is input from the monitoring apparatus 1 by a manager or the like, the monitoring functions of the higher-level apparatus 2 and the lower-level apparatus 3 are controlled so that the offset monitoring is enabled for the monitoring point B and the monitoring point C in the higher-level apparatus 2, and as a result, the offset monitoring becomes enabled for the monitoring point a, the monitoring point B, and the monitoring point C.
Further, the administrator or the like may input information of the current monitoring function and the monitoring function after the switching as the switching instruction.
In this case, the host device 2 performs switching control of each target monitoring point using the monitoring point whose switching target monitoring function is in an active state as the target monitoring point, based on the received information on the switching instruction and the information for switching functions.
As described with reference to fig. 8, the switching between the monitoring functions is not limited to the switching between the 2 types of monitoring functions, and the host device 2 may control the switching between the monitoring functions.
As described above, according to embodiment 1, the monitoring system is configured such that the monitoring apparatus 1 includes: a switching instruction receiving unit 11 that receives an instruction to switch the monitoring function for a target monitoring point among 1 or more monitoring points; and a switching instruction transmitting unit 12 that transmits information relating to the switching instruction received by the switching instruction receiving unit 11 to the host device 2, wherein the host device 2 includes: a switching instruction receiving unit 21 that receives information on the switching instruction transmitted by the switching instruction transmitting unit 12; a function determination unit 22 that determines which of the upper apparatus 2 and the lower apparatus 3 performs the monitoring function after the switching instructed by the switching instruction, based on the information on the switching instruction received by the switching instruction reception unit 21 and the function switching information indicating the correspondence relationship between the monitoring functions performed by the upper apparatus 2 and the lower apparatus 3; a lower invalidation instruction creating unit 252 that creates, for the lower device 3, lower invalidation instruction information for invalidating the monitoring function being performed on the target monitoring point when the function determination unit 22 determines that the monitoring function after the switching is the monitoring function performed by the upper device 2; an upper-level effective control unit 241 for enabling the switched monitoring function for the target monitoring point in the upper-level device 2 when the function determination unit 22 determines that the switched monitoring function is the monitoring function implemented by the upper-level device 2; an upper invalidation control unit 242 that invalidates the monitoring function that is being executed by the target monitoring point in the upper apparatus 2 when the function determination unit 22 determines that the monitoring function after the switching is the monitoring function executed by the lower apparatus 3; a lower significant instruction making unit 251 for making, in the case where the function determination unit 22 determines that the monitoring function after the switching is the monitoring function performed by the lower apparatus 3, lower significant instruction information for making the monitoring function after the switching for the target monitoring point effective for the lower apparatus 3; and a lower control instruction transmitting unit 26 that transmits the lower invalid instruction information created by the lower invalid instruction creating unit 252 or the lower valid instruction information created by the lower valid instruction creating unit 251 to a lower device, wherein the lower device 3 includes: a lower control instruction receiving unit 31 that receives the lower invalid instruction information or the lower valid instruction information transmitted from the lower control instruction transmitting unit 26; and a lower monitoring control unit that disables or enables the monitoring function for the target monitoring point by the lower device 3, based on the lower invalidation instruction information or the lower validity instruction information received by the lower control instruction receiving unit 31. Therefore, the switching of the monitoring function of the monitoring point to be monitored can be performed without suspending the system. Further, by automatically disabling the unnecessary monitoring function without the necessity of a control of stopping the unnecessary monitoring function every time by a manager or the like, it is possible to prevent the monitoring function from being doubly executed between the upper apparatus 2 and the lower apparatus 3.
In the present invention, any component of the embodiment may be modified or omitted within the scope of the present invention.
