Description

Technical Field

[0001] The present invention relates to a device for monitoring the electrical life of a railway signal relay, in particular to an electrical life monitoring method external to a railway signal relay, which can be installed outside the railway signal relay and can judge the suction and fall of the relay when it is working or testing, so as to make real-time monitoring and counting of the electrical life of the relay, realize the management of the railway signal relay from age to electrical life, more accurately grasp the use status of the equipment, and formulate a scientific and feasible maintenance plan. Background Art

[0002] At present, the maintenance of railway signal relays is roughly divided into overhaul, rotation repair and fault repair according to different models. Except for fault repair, the maintenance and replacement of relays are all determined by age. However, relays of the same age may have different preservation states in different lines, different stations and different cabinets. For example, a relay that has been used for ten years has been repaired. It has operated more than 1 million times on busy lines, but only 100,000 times on remote and idle lines. Different maintenance strategies should be adopted for these two relays in different usage states, and even the former can be scrapped in advance while the latter can continue to be used. However, according to the current cabinets and computer interlocking monitoring, there is no complete system and circuit that can truly reflect the number of times the relay equipment has operated. Summary of the invention

[0003] The purpose of the present invention is to provide an electrical life monitoring method for an external railway signal relay, which can monitor the electrical life of the relay in real time, provide reliable data support for its use, maintenance, and extended service, and also provide effective objective facts for analyzing relay failure problems, so as to quantify the electrical life of the relay and avoid safety hazards caused by extended service life.

[0004] The technical scheme of the present invention is: it relates to an electrical life monitoring method of an external railway signal relay, which is characterized by: comprising: a sensor unit, a monitoring counting unit, a belt monitoring relay, a clamping bracket mechanism and a power supply mechanism; the sensor unit and the monitoring counting unit are clamped on the relay cover by the clamping bracket mechanism; the sensor unit, the monitoring counting unit and the belt monitoring relay are provided with a DC 12V power supply by the power supply mechanism to maintain operation; the sensor units are respectively attached to both sides of the belt monitoring relay cover, the sensor incident light is below the armature stopper of the belt monitoring relay, and the sensor incident light will penetrate the cover after power is supplied And pass under the stop piece. When the relay starts to work, the iron core absorbs the armature, the armature and the stop piece will fit the iron core, then the incident light will be blocked, the sensor will transmit a "break" signal to the monitoring counting unit, and the monitoring counting unit will add 1 to the counting action; when the relay falls, the armature and the stop piece will return to the fallen state, then the incident light will be reconnected, the sensor will transmit a "connect" signal to the monitoring counting unit, and the monitoring counting unit will also add 1 to the counting action, and this will be repeated; each time the incident light is repeatedly absorbed or dropped to block or connect, an electrical signal will be transmitted to the counting unit to add 1 to its count, which will be used as the electrical life of the relay.

[0005] The sensor transmitter and the sensor receiving amplifier are fixed on the left and right of the upper end of the U-shaped bracket slot respectively, and the monitoring counting unit is fixed on the bottom of the U-shaped bracket slot, and the fixed sensor transmitter and the sensor receiving amplifier are electrically connected to the monitoring counting unit through an electrical interface respectively; the relay is placed on the U-shaped mouth of the U-shaped bracket slot, and the U-shaped bracket slot can be clamped with the relay cover in the form of adhesion or friction, and corresponding position slots of the sensor transmitter and the sensor receiving amplifier are reserved to form a relative position fixed structure; the U-shaped bracket slot can reserve a lead hole and a monitoring counting unit buckle at the lower rib position, and the buckle supports and fixes the unit.

[0006] The positions of the sensor transmitter and the sensor receiving amplifier are fixed on the relay cover. The position of the incident light emitted by the sensor transmitter is located in the gap between the armature assembly and the stopper when they are released, corresponding to the position of the sensor receiving amplifier.

[0007] The advantages of the present invention are that the actual relay action can be used to monitor the service life of the relay without changing the appearance and function of the relay itself and the circuit of the electrical combination cabinet. This method is more in line with the definition of the electrical life of the relay in the railway standard and has a high test accuracy. It can also monitor the relay outside the working state (such as when debugging the circuit or detecting and repairing), and is replaceable, which is very effective in monitoring the full life of the relay.

[0010] In order to further explain the technical means adopted by the invention to achieve the predetermined purpose, the specific implementation mode, structural features and effects of the invention are described in detail below in conjunction with the accompanying drawings and embodiments.

[0011] like Figure 1 , Figure 2 , Figure 3As shown, the present invention relates to an electrical life monitoring method for an external railway signal relay, comprising: a sensor unit, a monitoring counting unit 11, a clamping bracket mechanism and a power supply mechanism, the sensor units are respectively attached to fixed positions with a monitoring relay 1, specifically on both sides of a relay cover 2, the sensor incident light is below an armature stopper 6, after power is supplied, the sensor incident light penetrates the relay cover 2 and passes under the stopper 6 (when the relay is in a falling state), when the relay starts to work, the armature is sucked up by the iron core 7 due to electromagnetic force, the armature and the stopper 6 will fit the iron core 7, then the incident light will be blocked at this position, the sensor will transmit an "off" signal to the monitoring counting unit 11, and the monitoring counting unit The sensor unit 11 will count plus 1; when the relay falls, the armature and the stopper 6 will return to the falling state, and the incident light will be reconnected at that time. The sensor will transmit a "pass" signal to the monitoring counting unit 11, and the monitoring counting unit 11 will also count plus 1, and this will be repeated. Every time the relay is completely sucked up or dropped to block or connect the incident light, an electrical signal will be transmitted to the counting unit 11 to make its count plus 1, which will be used as the electrical life of the relay; the sensor unit and the monitoring counting unit 11 are clamped on the relay cover 2 by a clamping bracket mechanism to keep the two units from displacement and deflection during operation to affect the accuracy; both units are provided with a DC 12V power supply by the power supply mechanism 12 to maintain operation.

[0012] like Figure 2 , Figure 3 As shown, the entire external relay electrical life monitoring device includes a sensor transmitter 8, a sensor receiving amplifier 9, a U-shaped bracket slot 10, and a monitoring counting unit 11. The overall appearance and shape of the device are shown in the figure. The sensor transmitter 8 and the sensor receiving amplifier 9 are fixed on the left and right of the upper end of the U-shaped bracket slot 10, and the monitoring counting unit 11 is fixed at the bottom of the U-shaped bracket slot 10. The fixed sensor transmitter 8 and the sensor receiving amplifier 9 are electrically connected to the monitoring counting unit 11 through an electrical interface. The relay is placed on the U-shaped mouth of the U-shaped bracket slot 10.

[0013] like Figure 1 , Figure 2 As shown, the U-shaped bracket slot 10 can be clamped with the relay cover 2 in the form of adhesive force or friction force, and corresponding position slots for the sensor transmitter 8 and the sensor receiving amplifier 9 are reserved to form a relative position fixed structure; the U-shaped bracket slot 10 can reserve a lead hole 14 and a monitoring counting unit 11 buckle 15 at the lower rib position, and the buckle 15 supports and fixes the unit.

[0014] like Figure 3 and Figure 4As shown, in order to fix the incident light of the sensor transmitter 8 and the sensor receiving amplifier 9 at the expected position, it is necessary to fix the positions of the sensor transmitter 8 and the sensor receiving amplifier 9 at the illustrated position of the relay cover 2, and the incident light of the sensor transmitter 8 and the sensor receiving amplifier 9 can penetrate the gap between the armature assembly 3 and the iron core 7.

[0015] The position of the incident light emitted by the sensor transmitter 8 is located at the gap 13 when the armature assembly 3 and the stop plate 6 are released, corresponding to the position of the sensor receiving amplifier 9 .

[0016] like Figure 5A and Figure 5B As shown in the figure, they are schematic diagrams of the relay in the attracted state and the dropped state, respectively. It can be seen that the placement position of the relay body 1 when working, the attracted state Figure 5A When the armature assembly 3 is pulled forward by the electromagnetic force generated by the coil, the armature assembly 3 and the stopper 6 are attached to the core 7. At this time, the armature assembly 3 drives the contact group 5 to move forward, so that all the front contacts are connected. This is the working state; the falling state Figure 5B When the electromagnetic force disappears, the armature assembly 3 and the stopper 6 are separated from the iron core 7 due to gravity to form a gap 13. At this time, the armature assembly 3 drives the contact group 5 to pull back and connect all the rear contacts. This is the release time.
