The invention relates to a web control technology for an embedded device and discloses a web menu control system and method for the embedded device. Menu display control of embedded user authority is supported, and memory resources of the embedded device are saved. The method comprises the steps that a, a web client sends an access request to a web server after receiving the access request of a login user; b, the web server returns a main page to the web client after verifying user login information successfully; c, the web client sends an http request for obtaining the authority serial number of the authority owned by the current login user to the web server; d, the web processor processes the http request, queries the authority serial number owned by the current login user and feeds back the authority serial number to the web client; and e, the web client calls a pre-established interface function authority menu configuration file to obtain target menu data according to the obtained authority serial number owned by the login user, generates a corresponding display menu, reloads the display menu to the main page and displays the display menu to the user. The method and the system are applicable to the menu display control of the user authority of the embedded device.

The present application discloses a monitor system and a display control method thereof, wherein the monitor system includes: a control module for sending human-computer interaction interface information and background image information to a processing module through the same channel; a processing module for receiving video image information, and process the video image information, human-computer interaction interface information, and background image information, and output target image information to the display; the display is used to display the target image information. The system stores the background image information in the control module, so that the target image information can be displayed on the display through the information transmission and processing between the control module and the processing module, so as to realize the display control of the monitor system, no longer relying on additional The external device stores the background image information, which avoids the problems of high cost, difficult structure design and low control accuracy existing in the prior art.

The embodiment of the invention provides a display control method. The method comprises the following steps that: a basic clock inputs a counter, and the counter outputs a periodic digital signal; the periodical digital signal output by the counter enters a data gate through a logic combiner and a pulse width modulation PWM signal is output, wherein the duty ratio of the PWM signal is a preset threshold A; the highest updating frequency of the PWM signal is the preset threshold B; and output high pulses are distributed in a pulse width modulation standard period; and the PWM signal drives a light emitting diode LED for display control. According to the scheme provided by the invention, the pulse width modulation signal is generated at a higher frequency on the premise that the original data is not affected, so the display control at high updating frequency is realized. The scheme is realized simply and efficiently by logically combining the output of the counter and gating data.

The invention relates to the field of system communication scheduling algorithms, in particular to a system communication scheduling algorithm based on a Canbus. According to the specific scheme, the system communication scheduling algorithm is achieved through the following steps of firstly, sending address statements to a monitoring box when sub-devices are powered on, and sending address statement request commands to the sub-devices when the monitoring box is powered on; secondly, when receiving the address statement commands sent by the monitoring box, enabling the powered-on sub-devices to start the address statements which need to be responded to after random delay is conducted. By means of the steps, the system communication scheduling algorithm solves the address automatic distribution problem and the address conflict problem between the sub-devices and solves the problem that the operation control and the running state monitoring of all node devices can not be monitored in time; the Canbus can report device alarms in time when the number of online communication nodes is large, protection control can be conducted according to the alarms, the online state and the connection losing state of online devices can be effectively detected through the Canbus, and device display control over multiple nodes can be achieved through the Canbus.
