Circuit is the detected object of the utility model electric relay detection device as shown in Figure 2, the pin synoptic diagram of measured relay, above the relay board that uses in the launch vehicle measurement of carrier rocket ground is general three to four relays are arranged, when using the utility model to detect relay board, by winding displacement measured relay plate and proving installation are linked together, be to be plug end on the measured relay plate, socket end is positioned on the proving installation.Winding displacement has tens passages, to be on the safe side, specially two passages have all been distributed for each pin of relay, end plug as figure repeat circuit line bag has used passage 1 and 2, in the time of this relay board of test, plug on the relay board uses the passage label corresponding with the socket institute interface channel label on Fig. 1 repeat circuit proving installation, be connected together, that is to say, the utility model described in claims has 14 sockets, in actual fabrication with when using this proving installation, can substitute by the socket and the winding displacement of one 34 pin, for each socket provides 2 stitch, such 14 sockets use 28 stitch altogether, if the needs of expansion are arranged, can also use the more socket of stitch to meet the demands.
In the time of the busy relay plate, plug and socket are linked together, the corresponding relation that is equivalent to the passage label that is connected with socket according to plug like this is connected to relay circuit in the middle of the proving installation circuit.At first use the self-checking circuit part that electric relay detection device is carried out self check, it is closed self-test switch, at this time, the self-test switch lamp lights, and illustrates and switches on, and+28V power supply is added in each above the light emitting diode by lead, like this+just constituted path between 28V power supply, light emitting diode, resistance and the ground wire, this moment, all light emitting diodes all can be luminous, and this illustrates that all light emitting diodes all are good, do not have fault.After relay access proving installation circuit to be measured, the conducting because of the normally closed path of relay between the 11 socket and the 3rd socket, such first light emitting diode can be luminous, the one group of normally closed path that also passes through relay between the 12 socket and the 5th socket is communicated with, such the 3rd light emitting diode is also luminous, same reason, after the socket of the plug of relay board to be measured and proving installation was connected together, the first light emitting diode V1, the 3rd light emitting diode V3, the 5th light emitting diode V5 and the 7th light emitting diode V7 began luminous; Four normally closed paths that this relay is described are trouble-free normally.Subsequently, the closed line bag adds electric switch, at this time the line bag power up switch lamp begin luminous, simultaneously, relay line bag two ends power up, at this moment relay can begin action, because the characteristic of relay, normally closed path disconnects, often open the road closed communicating, like this, between the 11 socket and the 4th socket just the road of often opening of the connection by relay linked together, so at this time the first light emitting diode V1 extinguishes, the second light emitting diode V2 is luminous, in like manner, the 3rd light emitting diode V3 extinguishes, and the 4th light emitting diode V4 is luminous, the 5th light emitting diode V5 extinguishes, the 6th light emitting diode V6 is luminous, and the 7th light emitting diode V7 extinguishes, and the 8th light emitting diode V8 is luminous.So just explanation, all paths of this relay all are normally trouble-free, detection finishes.
It is K1 that this relay is set code name, be connected by winding displacement between relay and the proving installation, use the plug of one 34 pin to connect winding displacement on the relay, use the socket of one 34 pin to connect winding displacement in the proving installation, in the line bag power-up circuit of proving installation, 23,24 link to each other with the proving installation ground wire on the socket; The line bag powers up switch lamp "-" end and links to each other with ground wire; 1,2 link to each other with proving installation+28V bus with after the line bag powers up switch lamp "+" end and links to each other on the socket, and the line bag added electric switch be added to+28V bus and socket between 1,2 in order to control.
In the testing circuit of contact, 5,6,11,12,17,18,21,22 link to each other with+28V bus on the socket.3,4 link to each other with light emitting diode V1 anode on the socket; 7,8 link to each other with light emitting diode V2 on the socket; 9,10 link to each other with light emitting diode V4 anode on the socket; 13,14 link to each other with light emitting diode V3 anode on the socket; 15,16 link to each other with light emitting diode V7 anode on the socket; 19,20 link to each other with light emitting diode V8 anode on the socket; 25,26 link to each other with light emitting diode V6 anode on the socket; 29,30 link to each other with light emitting diode V5 anode on the socket.The negative terminal of light emitting diode V1～V4, V9～V12 links to each other with ground wire, and the protective resistance of the 3.6K Ω that connects between each light emitting diode and ground wire.
In the proving installation self-checking circuit, self-test switch lamp "-" end links to each other with ground wire; On the socket 3,4 with after self-test switch lamp "+" end links to each other, link to each other with proving installation+28V bus, and self-test switch be added to+28V bus and socket between 3,4 in order to control.
When relay line bag K1 two ends did not power up, contact K1 was failure to actuate, and then four normally closed paths are channel status, and this moment, light emitting diode V1, V3, V9, V11 were luminous; When line bag K1 two ends power up, contact K1 action, four normally closed paths disconnect, and often open the road and become channel status for four simultaneously, and this moment, light emitting diode V1, V3, V9, V11 extinguished, and light emitting diode V2, V4, V10, V12 are luminous simultaneously.
If when test phenomenon as mentioned above, illustrate that then components and parts and circuit pathways are working properly on the measured relay plate; If above-mentioned test phenomenon do not occur, as the unusual light on and off of light emitting diode, can conclude that then the relay contact closed-circuit working of diode correspondence is unusual, the troubleshooting of should next cutting off the power supply.
Testing circuit and detection method for all relays on the measured relay plate are all identical with K1, and the working condition of all relays and contact path thereof on can the simultaneous verification ejecting plate
Self-checking circuit: self-test switch is connected between positive bus-bar and the light emitting diode.Before the busy relay plate, proving installation should guarantee Key Circuit and the main components and parts non-fault of self earlier.Because line bag power-up circuit design and relatively simple for structure, used element is less and work is very stable, so do not consider self check during the design self-checking circuit at line bag power-up circuit, proving installation carries a self check plate, and its effect is with 3,4,7,8,9,10,13,14,15,16,19,20,25,26,29,30 short circuits on the socket.After connecting self-test switch, the self-test switch lamp is bright, all light emitting diodes on the proving installation, i.e. and V1～V4, V9～V12 is all bright, illustrates that proving installation contact test circuit is working properly, and components and parts are working properly, and at this moment, the relay board proving installation is working properly.
The utility model electric relay detection device function is simple, and is easy to use.Along with the application of the repeat circuit of rocket design now plate is more and more, utilize this pick-up unit can verify the working condition of components and parts and circuit pathways on the relay board fast, and the rapid fault location point of energy, in carrier rocket ground experiment and troubleshooting, brought into play important effect.
The utility model other not detailed description be technology as well known to those skilled in the art.
