Monitoring system for sucker rod

A monitoring system for a sucker rod, comprising:

• a) a monitor center;
• b) a remote wireless communication equipment;
• c) a movement detection and storage equipment of the sucker rod;
• d) a radio frequency reader/writer;
• and
• e) a radio frequency storage chip;
• wherein the remote wireless communication equipment communicates with the monitor center and connects with the movement detection and storage equipment of the sucker rod;
• the movement detection and storage equipment of the sucker rod connects with the radio frequency reader/writer;
• the radio frequency storage chip is disposed on the sucker rod to store information of the sucker rod;
• the radio frequency reader/writer reads or writes the information of the sucker rod from the radio frequency storage chip;
• the movement detection and storage equipment of the sucker rod detects and stores a motion state of the sucker rod, the motion state comprising a number of reciprocating or circumvolving movements and a load of the sucker rod;
• the remote wireless communication equipment sends the motion state stored in the movement detection and storage equipment of the sucker rod to the monitor center so that the monitor center obtains a work state of an oil well and the sucker rod therein;
• the monitor center feedbacks the work state of the oil well and the sucker rod therein and alerts an abnormal state of the oil well;
• and
• the movement detection and storage equipment of the sucker rod comprises a first main microprocessor and elements connected therewith, the elements connected to the first main microprocessor comprising a watchdog circuit, a signal conditioning circuit, a flash memory, and a USB interface circuit;
• the signal conditioning circuit is further connected with a current transformer;
• and the first main microprocessor is connected with the remote wireless communication equipment.
