Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to the scope of the described embodiments.

[0013] refer to figure 1 . For different solenoid valves in the market, BTS power devices can be selected in the market according to specific parameter requirements, so that the system can monitor the solenoid valves in real time. BTS power device can choose BTS410H2 power drive module. figure 1 The BTS power devices in BTS have the functions of overload protection, current limit, short circuit protection, thermal shutdown, overvoltage protection, fast demagnetization of inductive loads, undervoltage and overvoltage shutdown with automatic restart and hysteresis, electrostatic discharge (ESD) protection . The interface definitions of the BTS410H2 power drive module are shown in Table 1.

Abstract

The invention provides electromagnetic valve fault on-line monitoring equipment comprising a power device base transceiver station (BTS) which is cross-linked with an electromagnetic valve through a cable and a central processing unit which is connected with the BTS; the BTS receives a discrete input signal from a bus when outputting a signal; a driving current signal which is responded and output is rectified by a quick recovery rectifier diode and output to the electromagnetic valve, so as to drive the electromagnetic valve to work; meanwhile, a high-level electric signal is returned to a bus module of the central processing unit through an 'ST' pin port, so as to monitor the on and off of the electromagnetic valve on line; and when the current on an output wire is higher than preset current, the BTS outputs an interception signal from an OUT port through a built-in protection circuit, so as to automatically cut off a load access. The electromagnetic valve fault on-line monitoring equipment has the advantages of convenience in operation, installation and debugging. During the operation, when the equipment is power on, the current signal which drives the electromagnetic valve to work can be output as long as a 'high' command is sent out, and meanwhile, the on and off of the electromagnetic valve can be monitored on line.

Description

technical field [0001] The invention relates to a fault detection device of a solenoid valve, in particular to an on-line monitoring device for a fault of a solenoid valve. Background technique [0002] Solenoid valves are industrial equipment used for electromagnetic control, and are used in industrial control systems to adjust medium inversion, flow, speed and other parameters. The solenoid valve has a closed cavity, with through holes in different positions, and each hole leads to a different pipeline. The closed cavity is equipped with a valve body, and the two sides of the valve body are equipped with electromagnets, which side of the magnet coil is energized. The body will be attracted to which side, by controlling the movement of the valve body to block or leak different oil discharge holes, and the normally open hydraulic oil of the oil hole will enter different oil discharge pipes, and then push through the oil pressure The piston of the oil cylinder, the piston...
