Described upper casing right side edge position is provided with two plastic press keys, and this plastic press key jet surface has oil film.
The outside surface of described upper and lower shell all sprays oil film.
Described key zone comprises the operation push-button that several rules are arranged, the corresponding setting of several operation push-buttons of keyboard circuit and this.
Also be built-in with LCD MODULE in the described upper and lower shell, the viewing area correspondence on the PVC pad pasting is located at the top of this LCD MODULE.
Described keyboard master controller is supported the identification of CMOS high-low level.
This video camera supervisory keyboard can be controlled 255 video cameras simultaneously.
The beneficial effects of the utility model: video camera supervisory keyboard of the present utility model, it is simple in structure, the small and exquisite exquisiteness of volume, and is not only simple to operate, and is easy to carry; In addition, the utility model is by RS485 mode line, Liquid Crystal Module display operation result, by selecting different addresses, an one video camera supervisory keyboard can be controlled nearly 255 video cameras, for the market in a large number fixedly small camera more can a key control menu show, regulatory function, it is comparatively convenient to use.
In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.
Description of drawings
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by embodiment of the present utility model is described in detail.
In the accompanying drawing,
Fig. 1 is the external structure synoptic diagram of the utility model video camera supervisory keyboard;
Fig. 2 is the transmitting terminal signal Processing block diagram between the utility model video camera supervisory keyboard and the video camera;
Fig. 3 is that the receiving end signal between the utility model video camera supervisory keyboard and the video camera is handled block diagram.
Embodiment
For further setting forth technological means and the effect thereof that the utility model is taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
As shown in Figure 1, the utility model provides a kind of video camera supervisory keyboard, comprise: lower casing 2, be fastened on the upper casing 4 on the lower casing 2, be covered on Polyvinylchloride (PVC) pad pasting 6 on the upper casing 4, and be located at, lower casing 4, control circuit in 2, comprise the viewing area 62 of being located at the top on this PVC pad pasting 6, and be located at the key zone 64 of display screen below, this control circuit comprises the keyboard circuit 8 corresponding with key zone 64, keyboard master controller 10 with the electric connection of keyboard 8 circuit, the UART Universal Asynchronous Receiver Transmitter 12 of getting in touch with this keyboard master controller 10, and RS485 change-over circuit 14.
