Embodiment
For those skilled in the art can understand technical scheme provided by the present invention better, below in conjunction with specific embodiment, set forth.
Refer to Fig. 1, Fig. 2, Fig. 3, Fig. 1 is the principle schematic of the on-line performance test macro of frequency-variable air conditioner outdoor machine in the present invention; Fig. 2 is the principle schematic of control module in the middle of Fig. 1; Fig. 3 is the principle schematic of workstation unit in Fig. 1.
The on-line performance test macro of frequency-variable air conditioner outdoor machine provided by the invention, comprises industrial computer, workstation unit, middle control module, communication unit and order wire group.Middle control module is connected by order wire group respectively with tested off-premises station and workstation, and workstation is also connected by industrial-controlled general line with industrial computer.
Above-mentioned in the middle of control module specifically by: workstation telecommunication circuit, tested off-premises station telecommunication circuit, main control chip, ADC module etc. form.Main control chip is converted to the control command of tested test-run a machine by protocol conversion module after by telecommunication circuit receiving workstation cell command, by transferring to off-premises station with the telecommunication circuit of the common zero line of tested off-premises station, off-premises station carries out the test actions such as compressor operating, four-way valve switching, expansion valve switch, outdoor fan switching, solenoid valve switching after receiving by control command.
On the other hand, off-premises station while collecting test real time data and fault-signal in test process, control module in the middle of transmitting by telecommunication circuit, middle control module is converted to and workstation communications command by protocol conversion module, and real time data and fault-signal are sent to workstation, in addition, control module also gathers the information such as current electric current, voltage, power, refrigerant high-low pressure, air outlet temperature by transmitting module and voltameter, is sent in the lump workstation unit.
Above-mentioned workstation arranges module, user's operational module, historical data module, test judgement module etc. by middle control module telecommunication circuit, industrial computer telecommunication circuit, user and forms.User can arrange test parameter by workstation, sends test command and starts production test, and workstation feeds back current test result by display screen simultaneously.
Above-mentioned industrial computer is networked by industrial-controlled general line and each workstation, can realize concentrated setting, inquiry and test command.
The test concrete steps of the on-line performance test macro of frequency-variable air conditioner outdoor machine provided by the invention are as follows:
One, test is prepared:
Step 1, middle control module master control borad provide the toggle switch of a 1-127, need be by current test station successively dial-up during the middle control module master control borad of user installation, and the uniqueness with control module in the middle of determining in native system;
If step 2, conventionally all working standing-meeting detects the convertible frequency air-conditioner of same type in same detection space, before starting to detect, user, by industrial computer unification, information such as detecting type (one-to-one, drag many etc.), detection order (heat-freeze-expansion valve test-outdoor fan test), compressor test frequency, working time, criterion is set.It should be noted that native system also can arrange the testing standard that this workstation is single by workstation unit.
Control module and tested off-premises station telecommunication circuit in the middle of step 3, user connect, this telecommunication circuit adopts the current ring communication of zero line altogether conventionally, in this example, off-premises station and middle control module power unit are separately by zero line wiring altogether, so only need a communication cable for one-to-one system between the two, this example can extend at most frequency conversion one and drag four.
Two, test process:
In step 4, this example, workstation unit adopts master-slave mode RS485 to communicate by letter with middle control module, and wherein workstation unit is main frame, and middle control module is slave.
User starts after testing button, and the parameter that workstation unit is set according to user in advance sends test command to middle control module, and middle control module is sent to tested off-premises station by protocol conversion module after receiving test command.
The test command of control module in the middle of step 5, off-premises station receive, by the test of test command operation commodity, control module in the middle of the machine running status being sent to simultaneously.
Step 6, middle control module receive off-premises station feedack, add in addition the electric current that gathers by transmitting module, voltage, refrigerant pressure, outlet temperature etc., by protocol conversion module, are sent to workstation unit.
In the middle of step 7, workstation unit receive, after the information of control module, show each test parameter, in test, complete according to setup parameter judgement test result simultaneously.If workstation display screen demonstration is qualified for test passes, if test failure shows defective and alarm, show that defective specifying information is for customer analysis simultaneously.
Step 8, workstation unit are sent to industrial computer by all test parameters, and are stored in industrial computer Database Systems for inquiry later.
Compared with prior art, the on-line performance test macro of frequency-variable air conditioner outdoor machine provided by the invention, by full automatic Distributed Control System (DCS), solved that existing manual detection efficiency is low, False Rate is high etc. problem, and easy to operate.
