Embodiment Construction

[0031] Such as figure 1 As shown, the control system provided by the embodiment of the present invention includes a plurality of lower computers and an upper computer for controlling the plurality of lower computers, and the upper computer and the lower computers maintain a communication connection through a bus or an internal network.

[0032] Such as figure 2 As shown, the upgrade method of the lower computer includes:

[0033] Step S1, detection step: the upper computer respectively detects the software versions of the plurality of lower computers;

[0034] Step S2, judging step: judging whether the software versions of the multiple lower computers are consistent;

[0035] Step S2, upgrade step: when the software versions of the multiple lower computers are inconsistent, the upper computer selects one of the software versions as the common version in the system, and controls the lower computers in the system to upgrade to the common version.

[0036] It should be noted ...

Abstract

The invention discloses a method for upgrading lower computers in a control system. The control system comprises the lower computers and an upper computer for controlling the lower computers. The method includes steps: detection, to be more specific, the upper computer detects software versions of the lower computers respectively; upgrading, to be more specific, when the software versions of the lower computers are nonuniform, the upper computer selects one of the software versions as a universal version in the system and controls the lower computers in the system to upgrade to the universal version. By adoption of the method for upgrading the lower computers in the control system, software version uniformity of the lower computers in the system can be kept, so that convenience in controlis achieved. The invention further provides the control system which adopts the method.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a method for upgrading a lower computer in a control system and a control system. Background technique [0002] In a control system in which one upper computer controls multiple lower computers (such as an air-conditioning system consisting of one controller and multiple outdoor units), the optimization and upgrade of functional logic is becoming more and more frequent, in order to achieve better operating results , resulting in more and more lower computer program upgrade requirements. Conventional program upgrade solutions require the lower computer to have the network communication function connected to the Internet, that is, the lower computer can first connect to the network, log in to the server and download the latest program from the server, and then perform the upgrade operation. The limitation of this method not only increases the cost of the machine, but also is limite...
