Problems solved by technology

[0002] At present, the switch state of the load on the air conditioning unit is generally displayed through the display screen of the unit or the handheld operator, but the switch state is only the high and low level output by the output terminal of the control board according to the control logic, and cannot reflect the real load switch state.
If the output terminal of the control board is not connected to the load or the load fails to switch normally, in this case the status of the load switch seen through the display board is not true. At this time, the maintenance personnel need to check one by one to find the load fault.
At present, the load can only be turned on by turning on the load. If the load is turned on according to the control logic when the load fails, it may damage the motor, valve and other components on the unit, which will bring unnecessary trouble to the maintenance of the unit.

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0017] see figure 1 with figure 2 As shown, according to an embodiment of the present invention, the method for detecting load failure through the display screen debugging interface includes: forming a display interface on the display screen; associating the display interface with the load, and controlling the switch of the load through the display interface; Parallel indication device on the AC contactor between the load and the load.

[0018] The load switch state currently displayed on the display is the logic control state on the output terminal of the controller, that is, the level state, not the real load switch state. If the load cannot be switched normally due to a fault, it cannot pass the display. When the board sees the real switching status of the load, it needs to be ch...

Abstract

The invention discloses a method for detecting load faults via a display screen debug interface and a device. The method comprises steps of forming a display interface on a display; associating the display interface and load and controlling on and off of the load via the display interface; and parallelly connecting an indicator device with an alternating-current contactor between a controller and the load. In this way, on and off of the load can be achieved without starting of a device; load faults can be effectively detected; and safety during maintenance and repairing of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fault detection, in particular to a method and device for detecting load faults through a display screen debugging interface. Background technique [0002] At present, the on-off state of the load on the air-conditioning unit is generally displayed through the unit's display screen or a handheld operator, but the on-off state is only the high and low levels output by the output terminal of the control board according to the control logic, and cannot reflect the real load on-off state. If the output terminal of the control board is not connected to the load or the load fails to switch normally, the status of the load switch seen through the display board is not true in this case. At this time, maintenance personnel need to check one by one to find the load fault. At present, the load can only be turned on by turning on the load. If the load is turned on according to the control logic when the load fails, i...
