Abstract
The invention discloses a kind of multi-gang air-conditioner gateway Modbus communication protocols, the default value of gateway SLAVE ID is 1, when only there are one when gateway, use acquiescence SLAVE ID on circuit；When there is multiple gateways on circuit, each gateway needs to be used for distinguishing each gateway using different SLAVE ID, and the value of SLAVE ID can be modified by changing the value of holding register 5000；Timeliness of the present invention is good, communication efficiency is high.
Description
Technical field
The invention belongs to multi-gang air-conditioner gateway communication protocol correlative technology fields.
Background technology
In air-conditioning system, the communication network of multi-connected machine is the most complicated communication system in air-conditioning the inside, network equipment node
It is more, data interaction amount is big, communication distance is remote, data age and accuracy requirement are high, this to the communication of multi-connected machine propose compared with
High request.In traditional technology, the communication network of multi-connected machine is set up based on RS-485 communication modes mostly, and network is using master
From structure, i.e. main controller recycles roll-call slave, and slave responds the mode of main controller, causes traditional multi-gang air-conditioner system in this way
The poor in timeliness of significant data response in system, communication efficiency are low.
Invention content
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention to provide a kind of multi-gang air-conditioner gateway
Modbus communication protocols, timeliness is good, communication efficiency is high.
Technical solution：To achieve the above object, technical scheme is as follows：
Multi-gang air-conditioner gateway Modbus communication protocol methods：
The value of the default value of gateway S LAVE ID is 1, when on circuit only there are one gateway when, use acquiescence S LAVE
ID；
When there is multiple gateways on circuit, each gateway needs to be used for distinguishing each gateway using different S LAVE ID,
The value of S LAVE ID can be modified by changing the value of holding register 5000；
When gateway uses serial communication with computer end, acquiescence communications parameter is：9600,8 data bit of baud rate, 1 is stopped
Stop bit, no parity check.Serial communication parameter can be changed by changing the value of holding register 5008~5011；
When gateway is communicated with computer end using network interface, gateway default network address is 192.168.138.212, routing
192.168.138.1 acquiescence is communicated using UDP, port 502；It can be repaiied by changing the value of holding register 5014~5023
Change network communication parameter；Wherein network address and routing address can also be carried out by the button screen of WSU312：It presses simultaneously
3,4 number keys enter system setup menu, are then scrolled up and down in a menu by 1,2 number keys, and 3 number keys are acknowledgement key, 4 number keys
For cancel key；
Gateway can at most manage 256 interior machines, for the air-conditioning system of different brands, the real manageable most imperial palace of gateway
Machine number is different, and specific number can be multiplied by by the value of holding register 5026, i.e. largest packet number, i.e., maximum outer machine quantity
5028 value, i.e. every group of maximum device quantity, i.e. every outer machine most imperial palace machine quantity obtain；The air-conditioning of part brand cannot be distinguished
Outer machine, maximum group number are set as 1；Interior machine is ranked sequentially by group in gateway, maximum device number retention position is pressed in every group, in gateway
Interior machine number divided by every group of maximum air-conditioning number can obtain belonging to outer machine coding, remainder is that the interior machine in machine in addition encodes.
When parameter setting mistake, gateway power-off is please given, pins resetting button simultaneously when power-up, carrying out initialization to equipment sets
It sets.
Advantageous effect：The present invention provides 312 multi-gang air-conditioner gateway Modbus communication protocols of WSU/WCU, timeliness is good,
Communication efficiency is high.
Specific implementation mode
This agreement has used following four kinds of SMODBUS data types：
The value of the default value of gateway SLAVE ID is 1, when only there are one when gateway, use acquiescence S LAVE ID on circuit
；
When there is multiple gateways on circuit, each gateway needs to be used for distinguishing each gateway using different S LAVE ID,
The value of S LAVE ID can be modified by changing the value of holding register 5000；
When gateway uses serial communication with computer end, acquiescence communications parameter is：9600,8 data bit of baud rate, 1 is stopped
Stop bit, no parity check.Serial communication parameter can be changed by changing the value of holding register 5008~5011；
When gateway is communicated with computer end using network interface, gateway default network address is 192.168.138.212, routing
192.168.138.1 acquiescence is communicated using UDP, port 502；It can be repaiied by changing the value of holding register 5014~5023
Change network communication parameter；Wherein network address and routing address can also be carried out by the button screen of WSU312：It presses simultaneously
3,4 number keys enter system setup menu, are then scrolled up and down in a menu by 1,2 number keys, and 3 number keys are acknowledgement key, 4 number keys
For cancel key；
Gateway can at most manage 256 interior machines, for the air-conditioning system of different brands, the real manageable most imperial palace of gateway
Machine number is different, and specific number can be by the value of holding register 5026, and (i.e. largest packet number, i.e., maximum outer machine quantity) multiplies
It is obtained with 5028 value (every group of maximum device quantity, i.e. every outer machine most imperial palace machine quantity)；The air-conditioning of part brand can not area
Exceptionally machine, maximum group number are set as 1；Interior machine is ranked sequentially by group in gateway, and maximum device number retention position is pressed in every group, uses gateway
In interior machine number divided by every group of maximum air-conditioning number can obtain belonging to outer machine coding, remainder is that the interior machine in machine in addition encodes.
1. discrete magnitude inputs (Discrete Inputs)
2. coil (Coil)
3. input register (Input Register)
4. holding register (Holding Register)
5. default (holding register)
The above is only a preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
