Talking about the Realization of Fault Processing in Distance Education System

In the remote teaching numerical control system, if the detected video and audio signals do not meet the transmission standard requirements, the time control module causes the main control system to display the prompt and alarm to activate the standby device; if the detection meets the standard, the previous transmission device is closed, and the system Start running the continuous transmission transmission device to realize automatic switching of the propagation signal.

The teaching information data is accessed, modified, deleted, and automatically sorted and adjusted in a predetermined time sequence.

The fault handling module is mainly used to process and monitor the fault data information transmitted by the transmitting equipment due to the fault interrupt. In the patrol monitoring of the transmission equipment carried out by the automatic monitoring system, if an abnormal phenomenon is found, the automatic monitoring system immediately starts the fault processing module and performs corresponding display processing, that is, prompting or alarming; meanwhile, when the signal quality of the signal vibration is not When the system standard requirements or signal interruption are met, the module starts the fault processing module by interrupting.

The automatic monitoring module can automatically monitor and detect the working status of each device of each transmitting system, including the working power, current, voltage, power and signal source, excitation power amplifier, standing wave ratio and other parameter data of the device. If any of the above data does not meet the operating standards of the device, the module automatically enters the fault detection state.

The module has the function of proofreading and correcting the parameter data; controlling various working states such as automatic opening/closing of the transmitting device, and realizing automatic conversion of the standby transmitting device when the standing wave ratio parameter is greater than 1.2. Whether the various parameter data detected meets the standard status requirements of the system needs to be determined according to the specific quantity standard of the parameter data and the specific working state and standard of the transmission device.

Bitumen Heating Storage Equipment

Asphalt heating storage equipment is an important road construction equipment, mainly used to heat and store asphalt in order to carry out road construction and maintenance when needed. The equipment has the characteristics of high efficiency, safety and environmental protection, and can provide stable asphalt supply for road construction.

Asphalt heating storage equipment is mainly composed of heating device, storage tank and control system. The heating unit uses oil or gas burners to transfer heat to the asphalt to heat it to the proper temperature. Storage tanks are large containers used to store heated asphalt, generally made of high-temperature resistant materials. The control system is responsible for monitoring the operating status of the equipment and the temperature of the asphalt to ensure the safe and stable operation of the equipment.

The heating principle of asphalt heating storage equipment is to transfer heat to asphalt through thermal conduction, so that it is heated. Heating devices are generally divided into direct heating and indirect heating in two ways. Direct heating is the use of the burner directly into the storage tank, hot air through the contact of hot air with the asphalt to heat it. Indirect heating is the use of heat exchangers to heat the asphalt in the storage tank without direct contact with the air. The two heating methods have advantages and disadvantages, and need to be selected according to the actual situation.

Asphalt heating storage equipment heating speed, can quickly heat asphalt to the use of temperature, improve production efficiency. At the same time, the equipment also has environmental protection characteristics, reducing exhaust gas and smoke emissions, reducing the impact on the environment. In addition, the operation of asphalt heating storage equipment is simple and easy to maintain, which can meet the needs of various road construction and maintenance projects.

In short, asphalt heating storage equipment is an important road construction equipment, with high efficiency, safety, environmental protection and other characteristics. It can provide a stable supply of asphalt for road construction, improve construction efficiency, reduce the impact on the environment and waste of resources. The equipment has a wide application prospect in the field of road construction.
