What at present, port and pier mostly adopted is the relaxation cases of manual inspection ship mooring hawser.When boats and ships load-carrying or trend change, the situation of load skewness weighing apparatus may appear in mooring cable, if the personnel of patrolling and examining can not in time find, may play the generation that disconnected cable causes the accident that boats and ships and harbour, access bridge collide, so be badly in need of a kind of can the relaxation cases of ship mooring hawser being carried out automatic device for monitoring and be solved this problem.

Summary of the invention

The utility model is at the deficiencies in the prior art, is measuring-signal and develop a kind of high-precision electronic combined pressure sensor that utilizes with the tension force on the ship mooring hawser, handle by the computing machine online in real time, calculate the tension force on the hawser, reference when offering staff on harbour and the boats and ships and working, if surpass default limit value, can be by sound, light warning reminding staff's boats and ships cable tension monitoring system.The technological means that the utility model adopts is as follows:

A kind of pin type force cell is characterized in that sensing element is that pressure sensor is arranged on bearing pin inside, by transmission cable pressure signal is sent to table and send in the device; One end of described bearing pin is provided with flange, and the other end is provided with pickup groove; The pin type force cell is provided with oil supply hole and oil outlet, and wherein oil supply hole is positioned at the two ends of pin type force cell, and oil outlet is positioned on the wall of pin type force cell.

A kind of boats and ships cable tension monitoring system that adopts the pin type force cell is characterized in that the release mooring hook base is connected by the pin type force cell with release mooring hook, and snaps in the pickup groove by fixed pin and to fix; Wherein the pin type force cell is passed to sensor transducer with institute's measuring pressure signal, be processed into to import into behind the standard transducing signal by sensor transducer and carry out Treatment Analysis in the data processing unit, the back shows in real time that by display device the pressure signal after also can will handling by data line imports in the host computer; Described data processing unit also is connected with audible-visual annunciator and wireless transmitter module; Electronic equipment in the whole monitoring means is powered by power module; Described power module connects UPS and two kinds of power supply sources of AC power.

Owing to adopted technique scheme, pin type force cell that the utility model provides and boats and ships cable tension monitoring system, have the wireless transmit of sound and light alarm, real-time information and the real-time monitoring of host computer, make the slackness of ship mooring hawser can in time obtain detecting, guaranteed boats and ships and crewman's safety; In addition this system architecture simple, be convenient to produce, and usable range extensively is suitable for extensively promoting at each harbour and boats and ships harborage.
