Abstract
The utility model relates to a power control device capable of self-inspection and system detection. The power control device comprises a housing; a circuit board disposed in the housing; a transparent observation window disposed in the housing; an indicating lamp, which is disposed in the housing, and is connected with the circuit board; a groove disposed in the inner side of the observation window. The indicating lamp is disposed in the groove. The power control device is advantageous in that the switching-on time, the switching-off time, the switching-on times of the indicating lamp can be observed through the observation window, the different faults can be determined, and therefore the maintenance personnel can find out and eliminate the troubles timely with the help of the power control device.
Description
Technical field
The utility model relates to a kind of output control device, specifically can carry out the output control device that self check and system detect.
Background technology
The failure rate of output control device and power control system is relatively high, for convenience of maintenance, in output control device, add self check and system measuring ability, testing result shows with display lamp, and operating maintenance personnel just can fix a breakdown by the control device self check of view window readout power and system testing result.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of output control device that carries out self check and system detection, with convenient for maintaining.
For solving the problems of the technologies described above, the utility model provides a kind of output control device that carries out self check and system detection, comprise: housing, be located at the circuit board in housing, described housing is provided with transparent view window, in housing, be also provided with the pilot lamp being connected with circuit board, the inner side of described view window has a groove, and described pilot lamp is located in this groove, prevents that pilot lamp from will moving and impact observation.
The lateral surface of described view window is provided with the grid of a plurality of parallel alternate settings, so that light can be propagated by specific direction.
For water proof and dust proof, the junction of described view window and housing is provided with packing washer.
Described pilot lamp is bonded in described groove by transparent glue.
Described view window is convex lens, and the center of described pilot lamp is located on the focal length of described convex lens, so that the light of view window output is directional light.
The utility model adds self check and system measuring ability in output control device, and testing result shows with display lamp, and operating maintenance personnel are by the control device self check of view window readout power and system testing result.According to the lighting time of luminous indicating lamp, fall time, bright light number of times, determine different faults, thereby help operating maintenance personnel find in time and fix a breakdown.When fault is not got rid of, luminous indicating lamp will carry out fault demonstration repeatedly.
Technique effect of the present utility model: the utility model is by lighting time, fall time, the bright light number of times of signal recording apparatus register lamp, determine different faults, thereby can help operating maintenance personnel find in time and fix a breakdown, view window can water proof and dust proof, and can making to export light, propagate or export light by specific direction be directional light, can be convenient to observe.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the structural representation of output control device of the present utility model.
Embodiment
As Fig. 1, output control device of the present utility model, comprise: housing 1, be located at the circuit board 4 in housing 1, described housing 1 is provided with transparent view window 2, in housing 1, be also provided with the pilot lamp 3 being connected with circuit board 4, the inner side of described view window 2 has a groove, and described pilot lamp 3 is located in this groove, prevents that pilot lamp from will moving and impact observation.
The lateral surface of described view window 2 is provided with the grid of a plurality of parallel alternate settings, so that light can be propagated by specific direction.
For water proof and dust proof, described view window 2 is provided with packing washer with the junction of housing 1.
Described pilot lamp 3 is bonded in described groove by transparent glue.
Described view window 2 is convex lens, and the center of described pilot lamp 3 is located on the focal length of described convex lens, so that the light of view window 2 outputs is directional light.
For water proof and dust proof, described view window 2 is notch cuttype bayonet socket with the junction of housing 1, and is provided with packing ring.
By the multiple most common failure classification of output control device (or system), as: the fault such as bridge fault, system power supply brownout, the short circuit of motor phase line under bridge fault, control device on motor phase line open circuit, motor overload, control device.
When output control device (or system) is when switching on, working or having fault at every turn, output control device all carries out system detection, and testing result is shown by the luminous indicating lamp of output control device inside.According to the lighting time of luminous indicating lamp, fall time, bright light number of times, determine different faults, thereby help operating maintenance personnel find in time and fix a breakdown.When fault is not got rid of, luminous indicating lamp will carry out fault demonstration repeatedly.
The lighting time of luminous indicating lamp, fall time, bright light number of times represent different faults, and method is following table (output control device of take is applied to power-assisted as example) for example: in table ". "
Represent that lighting time is short, "-" represents that lighting time is long, can be ". " 2～3 times.
Described pilot lamp is the lamp of available a plurality of different colours also, by the color of lighting time, fall time, bright light number of times and lamp, carrys out failure judgement.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And these belong to apparent variation that spirit of the present utility model extended out or change still among protection domain of the present utility model.
