Embodiment
The signal boxcar that the utility model is used for the monitoring of Wind turbines automatic lubricating system can be monitored 1 cover or many cover automatic lubricating systems simultaneously, followingly sets forth to monitor two cover automatic lubricating systems.
With reference to shown in accompanying drawing 1, automatic lubricating system comprises lubricant pump 1, the power panel be connected with lubricant pump 1 and control panel 2 and lubrication distribution device 3.Lubricant pump 1 has low liquid level signal output function, and in normal operating conditions, it is a cut-off signal that this signal exports, and when low liquid level, this signal exports is a periodic pulse.Lubrication distribution device 3 has lubrication distribution signal output function, and in normal operating conditions, this signal exports as series of pulses, and when blocking occurs distributor, this signal exports as Chang Kai or normally closed.
With reference to shown in accompanying drawing 2, in this embodiment, the power panel of the lubricant pump of two cover automatic lubricating systems is all connected with external 220V/AC power supply by air-break switch F1, and the total output of power supply is greater than 160W.
The utility model is used for the signal boxcar of Wind turbines automatic lubricating system monitoring, the F1 auxiliary contact of input port X2 with X3, lubricant pump low liquid level signal input port X4 with X5 that comprise power input port X1, connect with lubricant pump control panel in automatic lubricating system, lubrication distribution device signal input port X6 with X7, integrated signal output port X9, action together with air-break switch F1 and its port x 8 and the single-chip microcomputer be connected with above-mentioned port and supplementary module.
The voltage of the power input port X1 input of this signal boxcar is 24V/DC, and this power supply is long power supply source.
This signal boxcar is one group with 3 signal input ports, monitoring 1 cover automatic lubricating system.In the present embodiment, input port X2, X4, X6 are one group, monitoring 1# automatic lubricating system; Input port X3, X5, X7 are one group, monitoring 2# automatic lubricating system.Certainly, those skilled in the art can expand above-mentioned input port according to actual conditions, and whether liquid level signal as low in lubricant pump, lubrication distribution device all reserved input port of jam signal and lubricant pump motor signal, to monitor more automatic lubricating system.
The F1 auxiliary contact of this signal boxcar are with air-break switch F1 action, and when air-break switch F1 tripping, F1 auxiliary contact are also by tripping.
The single-chip microcomputer of this signal boxcar and supplementary module carry out analysing and processing to above-mentioned input signal, finally processing signals are exported.
