Abstract

The utility model discloses a test box for an automatic control system of an air conditioner. A test box body is arranged on a movable trolley; an LCD (liquid crystal display) human-machine interface which can be input and output, an external power supply indicator lamp, a power supply switch, a test box power supply indicator lamp, a machine type selection key, a qualified indicator lamp, an unqualified indicator lamp and control panels are arranged on the front side of the test box, wherein the external power supply indicator lamp, the power supply switch, the test box power supply indicator lamp, the machine type selection key, the qualified indicator lamp and the unqualified indicator lamp are arranged at one side of the LCD human-machine interface; the control panels are arranged at the other sides of the human-machine interface and are provided with test select switches, refrigeration testing indicator lamps and heating testing indicator lamps; testing ports are arranged on the lateral surface of the test box; and a PLC (programmable logic controller) circuit, an air-break switch arranged at one side of the PLC circuit, a relay arranged on the other side of the PLC circuit and a switch power supply arranged adjacent to the air-break switch are arranged inside the test box. Compared with a test table of the air conditioner, the test box has a simple structure, can be used for displaying the specific test result, and is convenient to move; and test requirements can be set for multiple times.

Description

Air-conditioning automatic control system test box

Technical field

The utility model relates to a kind of air-conditioning automatic control system test box.

Background technology

Existing air conditioner test platform, control structure is comparatively complicated, show test mode by pilot lamp merely, the project organization of this air conditioner test platform is comparatively heavy, can only be fixed in laboratory or the workshop and test, and show that by pilot lamp the result of test is comparatively rough, can not show the concrete position of fault, and can only test at a kind of model air-conditioning, can not the secondary setting.

Summary of the invention

The utility model provide a kind of movably, air conditioner test platform that can show test results in detail, that test request can repeatedly be set.

For achieving the above object, the technical solution adopted in the utility model is: a kind of air-conditioning automatic control system test box, this test box is arranged on the travelling car, the front of described test box has the LCD man-machine interface that can import and export, be arranged on the external power supply pilot lamp of described man-machine interface one side, power switch, the test box power light, the type options button, qualified pilot lamp, defective pilot lamp, be arranged on other side of described man-machine interface and have the test selector switch, refrigeration test pilot lamp, heat the control panel of test pilot lamp, offer test port on the side of described test box, the inside of described test box has the PLC circuit, the sky that is arranged on described PLC circuit one side is opened, be arranged on the relay of described other side of PLC circuit, be close to the Switching Power Supply that described sky is arranged.

Preferably, described PLC circuit and described relay are conducted, and described PLC circuit and described sky are opened and be conducted, and described Switching Power Supply is opened with described PLC circuit by described sky and is conducted, and described Switching Power Supply is opened with described relay by described sky and is conducted.

Because technique scheme utilization, the utility model compared with prior art has following advantage: air-conditioning automatic control system test box designs for box-type, be placed on the travelling car, use man-machine interface and programmable PLC circuit core components and parts, can show the detection information that output is detailed by man-machine interface again according to the programming of test needs by the man-machine interface input as test box, simple in structure like this, show that specifically conveniently moving can repeatedly be provided with test request.
