[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a network variable binding method.
[0002]
[Prior art]
In recent years, distributed control of air conditioners, variable air volume devices, and the like installed in buildings has been studied by LonWorks (registered trademark of Echelon Corporation, USA) applying LON (Local Operation Network) technology.
[0003]
FIG. 2 shows an example of an air conditioning equipment operating system using LonWorks. In this air conditioning equipment operating system, AHU (Air Handling Unit)
1 and VAV (Variable Air Volume: variable air volume device) 2 for adjusting the amount of cold air or hot air sent from AHU 1 are connected to a LonWorks line (lower network line) 3 for each floor of the building, for example. An LSI having a communication function called a neuron chip is incorporated in AHU1 and VAV2.
[0004]
Furthermore, a gateway 6 is provided between the upper network line 5 and the LonWorks line 3 to which the central monitoring device 4 of the air conditioning equipment operation system is connected.
[0005]
The gateway 6 includes application software 7 for controlling the AHU1 and VAV2, and converts the communication protocol of the upper network into the communication protocol of the LonWorks, converts the communication protocol of the LonWorks to the communication protocol of the upper network, and then the neuron chip. Application software 8 for communicating with AHU1 and VAV2 via the network is held.
[0006]
Thereby, a command based on the data on the operation time zone and target room temperature of AHU1 and VAV2 set in the central monitoring device 4 is transmitted from the upper network line 5, gateway 6 and LonWorks line 3 to AHU1 and VAV2, Information obtained by sensors attached to the AHU 1 and VAV 2 is transmitted from the LonWorks line 3, the gateway 6, and the upper network line 5 to the central monitoring device 4, and automatic operation of the AHU 1 and VAV 2 is performed.
[0007]
For mutual communication between the gateway 6 and the AHU1 and VAV2, SNVT (Standard Network Value type) is adopted. Under this SNVT convention, network variables are assigned to each command or information to be communicated. It has established.
[0008]
The AHU1, VAV2, and gateway 6 devices are assigned network variables related to detection and command, such as device activation, shutdown, temperature, air volume, etc., which are the standard for monitoring. In addition, binding is performed in which network variables of individual devices are associated with other devices to be controlled or monitored to set destinations.
[0009]
When binding network variables, an information terminal (man-machine interface / personal computer) 10 holding graphic-based binding application software 9 is connected to the upper network line 5 and an engineer can While visually observing a schematic diagram of devices and network variables displayed on the display of the terminal 10, the pointing device (mouse) 11 is manually operated, and the network variable transmission destinations are connected to the neuron chips of AHU1, VAV2, and gateway 6, And the operation of setting the communication form (event driven / polling, ACK response / non-ACK response, priority / non-priority) is sequentially performed for each network variable.
[0010]
[Problems to be solved by the invention]
However, in the conventional binding method, since the pointing device 11 such as a mouse is operated for each network variable, it takes a long time to complete the binding of all the network variables, and the transmission destination of the network variables is information. Since it is visually confirmed on the display of the terminal 10, an erroneous setting is likely to occur.
[0011]
The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a network variable binding method that can shorten the work time and avoid erroneous setting.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, according to the network variable binding method of the present invention, network variables in an air conditioner operation system that performs distributed control of air conditioners such as an air conditioner and a variable air volume device installed in a building using LonWorks are provided. In the binding method, when the network variable between the air conditioners is bound via the graphic-based man-machine interface configured by operating the pointing device, the information terminal including the graphic-based man-machine interface the base of the data provided with the software to be converted to graphics-based man-machine interface to the data corresponding, program ID of the transmission source device, the location of the source equipment, program ID of the destination device, and Russia of the destination device Shon, and communicate consisting network variable record, after creating a text-based network variable record, the network variables between devices in the text-based network variable records created from the source device is a communication target to the destination device A text-based bind setting file is created by adding a code relating to the form, and then the text-based data is converted into data corresponding to a graphic-based man-machine interface using the text-based data. The bind setting file data is input to the graphic-based man-machine interface at once.
In addition, the communication mode of network variables between devices expressed by codes to be added to the created text-based network variable record is event-driven, binding cancellation, polling interval, presence / absence of ACK response, and priority among devices.
Further, an information terminal holding a graphic-based man-machine interface is connected to the upper network line, and a communication mode is set to the air conditioner and the gateway via the LonWorks line.
[0013]

[0016]
When a new air conditioning equipment operation system is established, the network variable list created at the time of design (AHU1, VAV2, and the network variables assigned to each equipment of the gateway 6 are controlled by other equipment to be controlled or monitored. Based on the list of which to associate, the program ID of the transmission source device (code indicating the device type), the location of the transmission source device (code for individual identification of the same type of device), the program of the transmission destination device A record of each data of the ID, the location of the transmission destination device, and the network variable to be bound from the transmission source device to the transmission destination device is created as a text-based bind setting file 12.
[0017]
That is, if the program ID of the source VAV2 is 00DVAV, its location is 11, the program ID of the destination gateway 6 is 22IG, its location is 33, and the network variable to be bound is nvoZZZ, the bind setting file 12 is created. The record at that time is displayed as follows.
[0018]
00DVAV, 11,22IG, 33, nvoZZZ
