The invention discloses an asphalt mixture loading system and control method based on machine vision. The system includes a van loading room, a material door mechanism, a vehicle moving platform and a machine vision control system. The vehicle moving platform includes a crawler flat plate , a longitudinal beam support, a roller mechanism and a roller driving mechanism, the machine vision control system includes a control module, an illumination device, a rotary encoder and a pressure sensor, as well as a video camera and a photoelectric sensor; the control method includes: step 1, asphalt mixture loading Preparations before the vehicle; Step 2, setting the loading parameters of the asphalt mixture; Step 3, fast flat loading; Step 4, precise flat loading; Step 5, pouring out the loading vehicle and recycling the material. The invention has the advantages of reasonable design, simple operation and good use effect, real-time control of the loading process of the asphalt mixture, realizing automatic flat loading of the asphalt mixture, effectively reducing the loading segregation of the asphalt mixture, and reducing environmental pollution.

The embodiment of the invention provides a method and a system for monitoring wireless network user behaviors. The method comprises that: a WEB Server receives a set monitoring condition; the WEB Server generates a configuration file according to the monitoring condition, and the configuration file comprises the monitoring condition; the WEB Server sends the configuration file to each App Server; in the proceeding process of mobile data service, each App Server transmits a command of starting a monitoring task to each front-end computer, and the command of starting the monitoring task comprises the configuration file; each front-end computer returns a user behavior record to the App Server to which the front-end computer belongs, and the user behavior record comprises a state of the mobile data service in the proceeding process; and the App Server receiving the user behavior record returns the user behavior record to a terminal through the WEB Server.

The invention relates to a detection circuit of active shielding wiring, and belongs to the technical field of safety protection detection of chips. The circuit comprises a first-stage amplifier, a stored-value circuit, a second-stage amplifier, an A / D converter, a CPU controller, a write-once memory and a comparator. The first-stage amplifier is composed of a first amplifier, a plurality of switches and a plurality of detected shielded wires. One end of the stored-value circuit is connected with the output end of the first-stage amplifier. The other end of the stored-value circuit is connected with the positive input end of the second-stage amplifier. The input end of the A / D converter is connected with the output end of the second-stage amplifier. The output end of the A / D converter is connected with the input end of the comparator. The CPU controller is respectively connected with the first-stage amplifier and the write-once memory. The write-once memory is connected with the CPU controller and the comparator. The input end of the comparator is respectively connected with the output end of the write-once memory and the output end of the A / D converter. The detection circuit can reduce the influences of mismatch of the circuit, the process bias of the circuit and the temperature of the circuit, and therefore the accuracy of the detection circuit is improved.
