Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 4, a cross flow fan controller of a power distribution cabinet includes a main body 1 and a display operation panel 2. The main body 1 is used for being mounted on a power distribution cabinet. The display operation panel 2 may be directly mounted on the main body 1 or communicatively connected with the main body 1 through a communication cable for controlling and monitoring the crossflow blower.

Specifically, the main body 1 generally takes a rectangular body structure and may include a base plate 11, a circuit board 12, and a cover 13. The base plate 11 and the cover 13 may be injection moulded from plastics. The base plate 11 has a flange 111 so that when the body 1 is mounted in a power distribution cabinet, the base plate 11 is located inside the power distribution cabinet and the enclosure 13 is located outside the power distribution cabinet. Namely, the main body 1 is clamped on a mounting hole arranged on the power distribution cabinet door. Therefore, the main body 1 is very convenient to mount and dismount, and does not occupy too much internal space of the power distribution cabinet.

The circuit board 12 is mounted in a cavity formed by the base plate 11 and the cover 13. Specifically, the circuit board 12 is fixedly mounted on the base plate 11, and the cover 13 is engaged on the base plate 11 to cover the circuit board 12. The circuit board 12 may include an MCU (e.g., HT66F0185) and peripheral circuits thereof, such as a power supply circuit, a communication circuit, a sensor sampling circuit, etc., and a specific circuit schematic thereof is shown in fig. 5 and will not be described herein. A crossflow blower terminal row 14 is provided on the circuit board 12, the crossflow blower terminal row 14 being for connection to a corresponding input or output of a crossflow blower. In the illustrated embodiment, the number of crossflow blower terminal rows 14 is 2, respectively provided on both sides of the main body 1 (specifically, the bottom of the housing 13). In this embodiment, two crossflow fans can be controlled by one power distribution cabinet crossflow fan controller, so that the installation space is saved. The side of the housing 13 above the crossflow blower terminal row 14 is provided with a terminal mark 133, and the terminal mark 133 is used for explaining the functional meaning of each terminal of the two crossflow blower terminal rows 14, see tables 1 and 2.

TABLE 1

TABLE 2

A first communication interface 15 is disposed on the top surface (specifically, the middle position) of the housing 13, and the first communication interface 15 is used for connecting (directly (as shown in fig. 1) or through a communication cable (not shown)) with a second communication interface 21 of the display operation panel 2, so that the display operation panel 2 can monitor the operation state of the crossflow blower in the power distribution cabinet (the rotation speed, the temperature, the fault information, and the like of the blower) and control the operation of the crossflow blower (normal or emergency start and stop). The first communication interface 15 and the second communication interface 21 are in a male-female matching structure. The specific specifications (length, wire diameter, core number and the like) of the communication cable can be set according to actual requirements. Because the display operation panel 2 can be directly installed on the main body 1 or separately installed with the main body 1 on the power distribution cabinet and then connected with each other through the communication cable, the installation of the controller becomes more flexible, a corresponding installation mode can be selected according to the specific specification of the power distribution cabinet, and the wiring of the cross flow fan is facilitated.

In the illustrated embodiment, the top surface of the housing 13 has a recess 131 sized and shaped to conform to the display operation panel 2, and the first communication interface 15 is disposed on the bottom of the recess 131. Therefore, the display operation panel 2 can be mounted in the recess 131. That is, the display operation panel 2 is embedded in the housing 13.

Preferably, the recess 131 is provided with a relief notch 132 on both sides thereof to facilitate the finger to grip the display operation panel 2 and to remove the display operation panel 2 from the recess 131.

The display operation panel 2 may have a display screen 22 and operation keys (not shown) provided below the display screen 22. The control of the crossflow blower is realized by the cooperation of the display screen 22 and the operation keys. The key operation interface description of the display operation panel 2 is shown in table 3. Of course, the display operation panel 2 may be a touch panel.
