Description

The electric horn interlocking apparatus computer monitoring device

The utility model relates to a kind of monitoring device of railway station electrical equipment, particularly a kind of electric horn interlocking apparatus computer monitoring device.

Electric horn interlocking apparatus is the equipment of the cover control safe train operation that uses of China railways system, and normally whether the operation of equipment is related to the safety of train and people's lives and properties.There is a problem in microcomputer monitoring in the past aspect switch acquisition, be exactly generally speaking for the collection of the actuating of relay, be to utilize its idle contact, but all contacts of the 1st starting relay 1DQJ all have other purposes, do not have idle contact to use, cause the collection inconvenience of the 1st starting relay 1DQJ action.

The purpose of this utility model is in order to understand the operation conditions of equipment better, alleviate a line railway worker labour intensity, realize the modernization of railway administration, scientific and the development a kind of electric horn interlocking apparatus computer monitoring device, it can gather the operating state of the 1st starting relay 1DQJ, the action current of acquisition trajectory track switch provides foundation for maintainer's service work.

The utility model is achieved in that the electric horn interlocking apparatus computer monitoring device is dimerous by acquisition interface 2 and monitoring main frame 3, wherein the IN of the switch acquisition device in the acquisition interface 2 imports the coil L of termination the 1st starting relay 1DQJ, 24 volts of power supplys of the positive termination monitoring slave of the mouth OUT of switch acquisition device, its negative terminal meets the switching value input end Ai of monitoring slave, the switch acquisition device comprises photoelectrical coupler OPTO, diode D, resistance R, with stabilivolt Z, diode D, connect the input end of photoelectrical coupler OPTO after resistance R and the stabilivolt Z serial connection, the input end Ai of the output termination monitoring slave switching value of photoelectrical coupler OPTO.

The structure of switch acquisition device of the present utility model has the electrical isolation effect, anti-interference resistance and safety and characteristics easy for installation.It adopts stable performance, failure-free photoelectrical coupler OPTO (521-1), makes the withstand voltage of input, mouth be not less than 1500 volts; Because the station power supply is more, in the sets of lines, generation is disturbed bigger, and string has stabilivolt Z (2CW12) in the switch acquisition device, and stabilivolt can suppress interference voltage, makes to sample accurately, stablize; Photoelectrical coupler OPTO's in the switch acquisition device is reverse withstand voltage lower, and this scheme is gone here and there a diode D (IN4007) in the line, can prevent from that the direct current input from connecing inverse time or exchanging reverse voltage to damage collector.The switch acquisition device is easy for installation, and design has special support 4, can directly be fixed on the original screw of unit block assembly rack by fixed orifice 10 during use.

Good effect of the present utility model is:

1, the utility model can will reach interval various information in the station, comprise all samplings such as analog quantity and switching value, give PC by interface and carry out analyzing and processing, and can information be delivered to departments such as electricity affair section, electricity affair division by the mode of telecommunication, so that in time grasp the firsthand information, make correct decisions.

2, switch acquisition device of the present utility model not only has electrical isolation, good in anti-interference performance, the characteristics that safety is good, and install and use very convenient.

3, the utility model can alleviate the labour intensity of shop floor worker, the modernization of realization railway administration and scientific.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1.The switching value of electric horn interlocking apparatus 1 and analog quantity by the centre the switch acquisition interface and the analog acquisition interface is translated into switching value information and analog quantity information is delivered in the computer monitoring device 3, technical personnel can be observed the running condition of electric horn interlocking apparatus 1 by the screen of PC.For example to the monitoring of rail switch electric current, when Platform attendant row route, when certain turnout will be moved, the first starting relay 1DQJ at first worked, voltage on its coil L is promptly adopted by the switch acquisition device, and gives monitoring slave switching value input end Ai with its signal.Electric current I 1 during the track switch action is monitoring slave acceptable analog quantity information through the analog acquisition interface conversion, and gives monitoring slave analog quantity input end D8 with this information.The indication lamp that the action of track switch makes expression track switch decide antiposition changes, and its state is a monitoring slave acceptable switching value information by the switch acquisition interface conversion, and gives the TX1 interface of monitoring slave.The monitoring slave is noted all these information, and gives PC through connection with information, by PC information is carried out analyzing and processing, and the current curve of the track switch of drawing action is for maintainer's reference.

Shown in Fig. 2,3, the input end of switch acquisition device is connected on the two ends of the coil L of the 1st starting relay 1DQJ, and mouth OUT (+) meets monitoring slave D1-A30, and this mouth is exported positive 24 volts of voltages, and mouth OUT (-) meets monitoring slave D1-A1, A2 ...When the 1st starting relay 1DQJ moved, the voltage of its coil L was added in the input end of switch acquisition device, and positive 24 volts of voltages of mouth OUT (+) just output to the monitoring slave from OUT (-), have finished the collection of switching value.

Shown in Fig. 4,5.Switch acquisition device body is small and exquisite, and has custom-designed support 4, can be directly during use be fixed on the unit block assembly rack on original screw by fixed orifice 10 on the support 4, uses very convenient.
