To improve the plant equipment of potential energy, for example water is mainly extracted into a high position by water pump from low level.And " heat pump " be one kind can be from nature
Lowlevel thermal energy is obtained in the empty gas and water or soil on boundary, is done work by electric energy, there is provided can be by the dress of the high level heat used in people
Put, the heat pump multi-connected machine control system that current each producer uses there are 2 kinds of situations, and one kind is one side plate mode, and another is
Two-sided plate mode, one side plate mode only have 1 panel, multiple equipment have been connect below the panel, once the panel breakage, client is just
The working condition of current all devices can not be known, it could even be possible to cause whole network to be paralysed, dual platen schema none
Exception all employ intercommunication line so that and live wiring is very mixed and disorderly, improves job costs, adds the workload of worker,
Operating efficiency is reduced, therefore in view of the above-mentioned problems, we have proposed a kind of heat pump redundancy control system.
Utility model content
The utility model discloses a kind of heat pump redundancy control system, can effectively solve to make single panel once damage at present
Bad, client can not just know the working condition of current all devices, it could even be possible to the problem of causing whole network to be paralysed, and
Two-sided plate mode uses intercommunication line so that live wiring is very mixed and disorderly, improves job costs, adds the work of worker
Amount, the problem of reducing operating efficiency.
In order to solve the above-mentioned technical problem, the utility model discloses following technical scheme：
A kind of heat pump redundancy control system of the utility model, including the first heat pump control panel and the second heat pump chain of command
Plate, the first heat pump control panel are connected with CAN control circuits, and the first heat pump control panel is controlled by the CAN
Circuit is connected with several heat pumps, and the second heat pump control panel is connected with described in several by the CAN control circuits
Heat pump, and principal and subordinate is not differentiated between multiple heat pumps, the CAN control circuits include MCU, and the MCU is connected with CAN controls
Device processed, the CAN controller are connected with CAN transceiver, and the CAN transceiver is connected with interface, and the heat pump passes through patchcord
It is connected with interface.
As a kind of optimal technical scheme of the present utility model, the first heat pump control panel, the second heat pump control
Panel processed and the heat pump are in same belonging network bus.
As a kind of optimal technical scheme of the present utility model, the first heat pump control panel is main control panel, institute
It is standby control panel to state the second heat pump control panel.
The beneficial effect that the utility model is reached is：The utility model main control panel is in same with standby control panel
In one network, when main control panel is out of order, standby control panel can changes the role of oneself by backup panel at any time
Use is converted to, when main control panel reparation is completed, after reaching the standard grade again, standby control panel will automatically detect main control
The state that panel is reached the standard grade, while also stand-by state automatically can be converted into by use state, the transfer process of this some row is not
Human intervention is needed, greatly improves the stability of whole network, is also solved conventional because single panel failure is led
The situation for causing all devices not run, has good economic benefit and social benefit, suitably promotes the use of.

Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment：As Figure 1-3, a kind of heat pump redundancy control system of the utility model, including the first heat pump chain of command
The heat pump control panel 4 of plate 1 and second, the first heat pump control panel 1 are connected with CAN control circuits 2, the first heat pump control panel 1
Several heat pumps 3 are connected with by CAN control circuits 2, the second heat pump control panel 4 is connected with some by CAN control circuits 2
Individual heat pump 3, and principal and subordinate is not differentiated between multiple heat pumps 3, CAN control circuits 2 include MCU5, and MCU5 is connected with CAN controller
6, CAN controller connects 6 and is connected to CAN transceiver 7, and CAN transceiver 7 is connected with interface 8, and the heat pump 3 passes through patchcord and interface 8
