Abstract
The invention relates to an automatic communication test method of a ball holder circuit; the automatic communication test method comprises the following steps that a 232/485 switching card is connected with a PC (Personal Computer) serial port and a 485 communication network so as to realize the switching between 232 level and 485 level; a 485 control signal is transmitted to the ball holder circuit by a communication network; a 485 switching chip of the ball holder circuit converts the transmitted 485 control signal to a TTL (Transistor-Transistor Logic) level signal which can be recognized by a microprocessor and transmits the TTL level signal to the microcomputer; and a ball machine counts data packets respectively which are successfully received and transmitted and shows the reliability of the bidirectional data communication to a user in percentage, thereby providing very great convenience for construction and maintenance staffs during field troubleshooting.
Description
Technical field
The present invention relates to the intelligent video monitoring technical field, particularly a kind of communication automatic test approach that is applied to the ball The Cloud Terrace circuit of safety monitoring, infrared ball monopod video camera and intelligent high-speed ball monopod video camera.
Background technology
In the safety defense monitoring system work progress, running between main control device and the control point through regular meeting can not normal communication or the insecure situation of communication, thereby can not realize the motion control of The Cloud Terrace.Occasion for fully can not communication need be investigated whole communication line, fixes a breakdown a little one by one.Reasons such as because considerable part site operation circumstance complication, the communication line wire rod is selected for use nonstandard, and the design of communication line topological structure is unreasonable make that the insecure situation of communication line transfer of data is more prone to take place.And for the insecure situation of communication line, fault is not easy investigation, and whole communication line reliability of data transmission is difficult to quantize more.Therefore, show important for the automatic test of the communication of ball The Cloud Terrace circuit is outstanding.
Summary of the invention
The object of the invention is exactly the deficiency that exists to prior art; To the problems referred to above, a kind of communication automatic test technology scheme is provided, make ball The Cloud Terrace circuit increase the communication autorun; Under the insecure situation of communication line; Can pass through the communication reliability of the PC test site circuit of incoming communication circuit, and with its quantification, thereby make the field failure investigation more directly perceived.
The present invention realizes through such technical scheme: the communication automatic test approach of ball The Cloud Terrace circuit, it is characterized in that, and comprise the steps:
(1) 232 interfaces, one end with 232/485 transition card connects PC serial ports end, and 485 interfaces, one end is connected to 485 communication networks, is used to realize serial ports of computers 232 level and 485 level conversion;
(2) 485 control signals transfer to ball The Cloud Terrace circuit through communication network, and 485 conversion chips of ball The Cloud Terrace inside circuit are converted into 485 control signals that transmit the discernible Transistor-Transistor Logic level signal of microprocessor and are transferred to microprocessor;
(3) the communication test software that runs on the PC end sends the communication test packet for ball The Cloud Terrace circuit;
(4) ball The Cloud Terrace circuit is added up the communication test packet that receives, and sends the reply data bag through 485 communication networks to PC;
(5) PC is added up the reply data bag that receives;
(6) behind the EOT, ball machine main circuit is added up respectively the packet that successfully receives and send, and is shown to user side to the reliability of two-way data communication with the form of percentage.
Beneficial effect of the present invention: through realizing the communication autorun of ball The Cloud Terrace circuit; Very big convenience is provided for construction and maintenance personal's field failure investigation; Through quantizing the data communication reliability, make the workmen understanding of visual and clear more arranged to the working condition of the communication line of engineering site.

Embodiment
Understand the present invention for clearer, describe the present invention in detail in conjunction with accompanying drawing and embodiment:
As Fig. 1, shown in, the automatic test network of communication of ball The Cloud Terrace circuit comprises PC, 232/485 transition card, 485 communication networks and ball The Cloud Terrace circuit, ball The Cloud Terrace circuit comprises microprocessor and 485 conversion chips;
Method of attachment is: 232/485 transition card, one end is connected PC serial ports end, and the other end is connected to 485 communication networks, is used to realize serial ports of computers 232 level and 485 level conversion; 485 control signals transfer to ball The Cloud Terrace circuit through communication network, and 485 conversion chips of ball The Cloud Terrace inside circuit are converted into 485 control signals that transmit the discernible Transistor-Transistor Logic level signal of microprocessor and are transferred to microprocessor;
Communication auto test flow as shown in Figure 2 is:
Communication test begins;
Receive test packet;
The echo reply packet;
Receive the communication test halt instruction;
The statistics communication reliability;
The statistics communication reliability.
According to above-mentioned explanation, can realize scheme of the present invention in conjunction with art technology.
