Description
Technical field
The present invention relates to central air conditioner system slave computer data routing inspection mode technical field, and in particular to one kind improves center
The method of the more slave computer polling rates of air-conditioning system.
Background technology
Host computer refers to that people can directly send the computer of manipulation order, usually PC, and various signals are shown on screen
Change (hydraulic pressure, water level, temperature etc.).
Slave computer is the computer that direct control device obtains status of equipment, usually PLC/ single-chip microcomputers etc.It is upper
Slave computer is given in the order that machine is sent first, and slave computer is accordingly set further according to this command interpretation into the directly control of corresponding time sequence signal
It is standby.Slave computer reads device status data (generally analog quantity) frequently, is converted into data signal and feeds back to host computer.
Central air conditioner system is made up of one or more cold and heat source systems and multiple air handling systems.Using liquid gasification
The principle of refrigeration provides institute's chilling requirement for air handling system, to offset the refrigeration duty of indoor environment；Heating is air
Regulating system provides institute's calorific requirement, to offset indoor environment thermic load.Central air conditioner system is made up of multiple coolant systems, often
Individual coolant system is made up of Master an ODU, multiple Slave ODU and multiple IDU, and Master ODU are managed collectively,
Each Master ODU serial ports is connected with a 410s, realizes being transferred into and out for data.
Central air conditioner system slave computer data routing inspection is slow, and when being related to a large amount of slave computer inspections, host computer is sent to slave computer
Inspection instruction, typically have a gap periods, if inspection order is more, and slave computer substantial amounts, that is completed once
The time of inspection will be very long, after some time it is possible to reach several hours.Overlong time efficiency is very low.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, there is provided a kind of raising more slave computer polling rates of central air conditioner system
Method.
To solve above-mentioned technical problem, the present invention uses following technical scheme：
A kind of method for improving the more slave computer polling rates of central air conditioner system, described method comprise the following steps：
Step 1, inspection device is provided with grid；
Step 2, the communication interface according to slave computer, mixed-media network modules mixed-media is added for slave computer；And Configuration network module parameter,
Preset IP address is specified, points to inspection device, and is configured in the message of mixed-media network modules mixed-media transmission, addition numbering, to distinguish
Different slave computers；
After step 3, slave computer start, according to default IP address, establish TCP with the inspection device and be connected；
Step 4, the inspection device persistently carry out inspection to slave computer, the numbered packets by information according to slave computer, protect
Exist in inspection device；
After step 5, host computer start, according to default IP address, establish TCP with inspection device and be connected, then directly from patrolling
Examine all data that slave computer is obtained in equipment.
Compared with prior art, one of beneficial effect of the embodiment of the present invention is：Method for inspecting provided by the invention, it is the next
Not direct communication between machine and host computer, add after inspection device in network, the slave computer in network can be carried out always
Inspection, in addition to polling period is very long when disposing first time, other when host computer once bottom can be obtained immediately once startup
Machine information, in view of under slave computer majority scene, Parameters variation is little, so the information of collection is smaller by the influence of time delay.
Brief description of the drawings
Fig. 1 is the routine inspection mode schematic diagram of one embodiment of the invention.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), except non-specifically chatting
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
Below in conjunction with the accompanying drawings and the embodiment of the present invention is described in detail embodiment.
In the following detailed description, many specific descriptions are described for illustrative purposes so as to thoroughly understand institute
Disclosed embodiment, it is clear, however, that one or more embodiments can be in the case of without using these specific descriptions
Implement, in other instances, known structure and device are schematically shown, to simplify accompanying drawing.
As shown in figure 1, according to one embodiment of present invention, under the present embodiment discloses a kind of raising central air conditioner system more
The method of position machine polling rate, specifically, this method comprises the following steps：
Step 1, not direct communication between slave computer and host computer, a special inspection device is added in network
(such as：Linux or Android box).
Step 2, according to the communication interface of slave computer, mixed-media network modules mixed-media is added for slave computer (such as RS485 turns ether).And
Configuration network module parameter, preset IP address is specified, point to inspection device, and matched somebody with somebody in the message of mixed-media network modules mixed-media transmission
Put, addition numbering, to distinguish different slave computers.
Step 3, after slave computer starts, according to default IP address, establish TCP with inspection device and be connected.
Step 4, inspection device does not stop to carry out inspection to slave computer, the numbered packets by information according to slave computer, is stored in
In inspection device.
Step 5, after host computer starts, also according to default IP address, establish TCP with inspection device and be connected, afterwards directly
All data of slave computer are obtained from inspection device.
The disclosed method for improving the more slave computer polling rates of central air conditioner system of the present embodiment, by adding in a network
After inspection device, inspection can be carried out to the slave computer in network always, in addition to polling period is very long when disposing first time,
Other when host computer Yi Dan start once can obtain the next machine information immediately, in view of under slave computer majority scene, Parameters variation is not
Greatly, so the information of collection is smaller by the influence of time delay, routing inspection efficiency is substantially increased.
