Embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises first current sensor 1, second current sensor 2, change-over circuit 3, processor controls 4 and warning panel 5; Two reverse stacking of current sensor are separately positioned on the Platform Screen Door cable, and two current sensors link to each other with change-over circuit 3 respectively, and change-over circuit 3 links to each other with processor controls 4, and warning panel 5 links to each other with processor controls 4.
First current sensor 1 is used to gather the current value of forward on the Platform Screen Door cable, and second current sensor 2 is used to gather current value reverse on the Platform Screen Door cable.Realization is to the forward and reverse mobile monitoring of electric current, the flow direction of electric current no matter, and its numerical values recited all can be uploaded by collection, and with positive and negative form sign, in the communications protocol of uploading, increase a binit discrimination bit, just be represented as, be represented as negative with " 1 " with " 0 "; On the terminal interface of monitoring, adopt the drawing benchmark system of four-quadrant two-dimensional coordinate axle, X-axis is a chronomere, Y-axis is a current unit, promptly represents negative current magnitude in four-quadrant electric current present value;
Current sensor is a kind of closed-loop sensors of utilizing Hall effect, and lead is pressed the direction that the right-hand rule in the electromagnetics is stipulated, passes loop sensor, after existing electric current to flow in the lead, the output of corresponding simulating magnitude of voltage will be arranged on current sensor; In this monitoring device, adopt the reverse mode that stacks to be installed on the cable that integrates with two current sensors, when flowing through forward current in the cable, meet and produce induced voltage in the sensor of the right-hand rule of this direction and output in the change-over circuit, can not produce induced voltage in the sensor of the right-hand rule of this direction and meet this moment; When flowing through the opposite direction electric current in the cable, its observation process is identical.The reverse mode that stacks by two current sensors is gathered bidirectional current.
Change-over circuit 3 is obtained actual current value after being used for this aanalogvoltage handled by analog quantity/digital quantity (A/D), and least unit is 1mA;
Processor controls 4, be used for actual current value and the parameter threshold values set are compared, if surpass threshold values, then drive warning panel 5 and send warning message, as light pilot lamp or drive hummer, being convenient to the staff in time handles, processor controls 4 is transferred to real-time data base 6 with all data by communication interface, external system reads the real-time information of real-time data base 6, the insulation variation tendency is presented on the man-machine interface terminal display of external system such as shield door control system, be convenient to staff's judgment processing, realize monitoring the state of insulation of shield door.
Simultaneously, the frequency of the current sample of current sensor and cycle, but and equal on-line setup such as the threshold values of reporting to the police.
As shown in Figure 2, the utility model is as follows to the process of shield door intelligence insulating monitoring:
(1) gathers forward and reverse current value on the Platform Screen Door cable, utilize Hall effect to be converted to corresponding aanalogvoltage and import as analog quantity;
(2) after being handled by analog quantity/digital quantity (A/D conversion), described aanalogvoltage obtains actual current value;
(3) actual current value and the parameter threshold values set are compared,, then send warning message if surpass threshold values;
(4) all information is transferred to real-time data base 6 by the communication interface communication.
