Description

Embodiments described herein relate generally to a gateway device, an abnormality monitoring system, an abnormality monitoring program, and an abnormality monitoring method.

HMI, which is a central monitoring device in a system for monitoring power in office buildings, etc.
(Human Machine Interface) monitors or controls the usage status of many equipment. Due to the introduction of a new system, the controller that controls the equipment is not updated, and only the HMI may be updated to a new device.

When the communication protocol of the existing controller and the newly installed HMI is different, a gateway device that converts the communication protocol is required. However, the functions were not unified. One of the functions is an abnormality monitoring function.

The abnormality monitoring function is a function of transmitting a state input signal indicating an abnormality out of state input signals indicating the current state of the facility equipment acquired from the controller to the HMI. Even if the existing HMI can detect the abnormality, the new HMI may not be able to detect the abnormality depending on the transmission form.

Therefore, the controller may not be able to transmit to the HMI that the state of the equipment is abnormal. If it cannot be transmitted to the HMI that there is an abnormality, there is a problem that an alarm or the like that is issued when an abnormality has occurred does not sound and the countermeasure for the abnormality is delayed.

(Embodiment)
(Constitution)
FIG. 1 shows a specific example of the configuration of the entire abnormality monitoring system of the gateway device according to the present embodiment. An anomaly monitoring system is, for example, a new HMI (Human Machine Interface)
2, the gateway apparatus 1 and the controllers 31-33 are provided. The existing HMI 5, the controllers 31 to 33, and the equipment devices 41 to 43 are existing, and the new HMI 2 and the gateway device 1
Is newly established.

The existing HMI 5 installed in the central monitoring room of the building transmits signals to the controllers 31 to 33 for controlling the equipment devices 41 to 43 such as air conditioners and lighting facilities. In addition, equipment 41-
43 states are received from the controllers 31-33. The network used at that time is the first network.

The newly installed HMI 2 installed in the central monitoring room of the building transmits a command to control the equipment devices 41 to 43 such as air conditioning equipment and lighting equipment to the gateway device 1. In addition, equipment 41 to 4
3 is received from the gateway device 1. The network used at that time is the second network.

The gateway device 1 communicates with the controllers 31 to 33 and the newly installed HMI 2. The network used when communicating with the controllers 31 to 33 is the first network. The network used when communicating with the new HMI 2 is the second network. The gateway device 1 is located at the boundary between the first network and the second network. However, the communication protocols of the first network and the second network may be the same or different.

The controllers 31 to 33 communicate with the equipment devices 41 to 43 and control each equipment device. The controllers 31 to 33 send control output signals for controlling each facility device to the facility devices 41 to 41.
43, and the state input signal which is the present state of the equipment is received from the equipment 41-43. Further, the controllers 31 to 33 determine whether or not the state input signal is an abnormal value.
If it is an abnormal value, it is transmitted as an error to the upper device.

In FIG. 2, the example of a block diagram of the gateway apparatus 1 is shown. The gateway device 1 includes an acquisition unit 11
, Storage unit 12, output unit 13, determination unit 14, and setting unit 15.

The acquisition unit 11 acquires a state input signal that is the current state of the equipment devices 41 to 43 from the controllers 31 to 33. State input signals include, for example, the current values of humidity and temperature, O
The signal includes information such as N or OFF, or information indicating abnormality.

The storage unit 12 stores a state input signal that can be sensed by the new HMI 2. The state input signal that can be sensed by the new HMI 2 is a signal that can be sensed and processed by the new HMI 2. For example,
When there are a plurality of signals indicating that the state of the equipment 41 to 43 is abnormal due to the settings of the controllers 31 to 33, the new HMI 2 can detect that the state input signal that can be detected by the new HMI 2 is abnormal. Signal.

The output unit 13 outputs the state input signals from the controllers 31 to 33 to the new HMI 2. When outputting, the output unit 13 outputs a state input signal that can be sensed by the new HMI 2 to the new HMI 2. For example, when the state input signals from the controllers 31 to 33 indicate an abnormality, a state input signal indicating an abnormality that can be detected by the new HMI 2 is output to the new HMI 2.

The determination unit 14 determines whether or not the state input signals from the controllers 31 to 33 can be sensed by the new HMI 2. That is, the state input signals from the controllers 31 to 33 are stored in the storage unit 1.
2, it is determined whether the input signal is a state input signal that can be sensed by the newly installed HMI 2.

For example, when there are two types of status input signals, engineering value and FAULT bit, and the newly installed HMI 2 cannot sense a part of the signal indicating abnormality output as the engineering value, the determination unit 14 receives the status from the controllers 31 to 33. It is determined whether the input signal is a status input signal indicating an abnormality, whether the status input signal is an engineering value, whether the status input signal is an engineering value that cannot be detected by the newly installed HMI 2, or the like.

When the determination unit 14 determines that the state input signal cannot be detected by the new HMI 2, the setting unit 15 sets the state input signal that can be detected by the new HMI 2 and stored in the storage unit 12.

(Function)
FIG. 3 shows a flowchart regarding the operation of the gateway device 1 according to the present embodiment. The flowchart of FIG. 3 shows the newly installed HMI 2 to the gateway device 1 and the controllers 31 to 3.
3, after outputting a control output signal for controlling the equipment 41 to 43 to the equipment 41 to 43, or from the existing HMI 5 through the controllers 31 to 33, the control output signal is output to the equipment 41 to 43. Then, it is a flowchart when the state input signal which is the state of the equipment 41 to 43 is input to the new HMI 2 through the gateway device 1.

The state input signal is determined by the controllers 31 to 33 as to whether or not it is an abnormal value.
An abnormality is transmitted to the existing HMI 5 or the gateway device 1 that is a higher-level device.
FIG. 3 shows a flowchart until the status input signal transmitted to the gateway apparatus 1 is output to the new HMI 2.

First, the acquisition part 11 acquires a state input signal from the controllers 31-33 (S11).
The state input signal to be acquired is, for example, that the state of the equipment 41 to 43 is abnormal, humidity,
It is a signal that conveys information such as temperature and whether or not the vehicle is operating.

Next, the determination unit 14 determines whether or not the status input signal from the controller can be sensed by the new HMI 2 (S12). Specifically, it is determined whether or not the state input signals from the controllers 31 to 33 are the same as the state input signals that are stored in the storage unit 12 and can be sensed by the new HMI 2.

(I) When the state input signal cannot be detected by the newly installed HMI 2 (No in S12)

After that, when the status input signal cannot be detected by the newly installed HMI2, the setting unit 15 sets the status input signals from the controllers 31 to 33 as the status input signals that can be detected by the newly installed HMI2 (S13). The state input signal to be set is a state input signal that can be detected by the newly installed HMI 2 and is stored in the storage unit 12.

Then, the output unit 13 sends a state input signal that can be detected by the newly set HMI 2 to the newly set HM.
