Description

Technical Field

[0001] This invention relates to the field of fully automated unmanned driving technology for rail transit, specifically to an audible and visual alarm circuit and its standardized assembly for safety protection in depot parking lots. Background Technology

[0002] With the widespread adoption of fully automated driving in urban rail transit, depots and parking lots have also become automated, featuring automated operating areas. While these automated operating areas are generally unmanned, drivers are still required when trains enter non-automated areas, and manual repairs are necessary if a train malfunctions in an automated area. Therefore, both the driver and maintenance personnel inevitably need to enter the automated area. However, currently, automated areas lack automatic pre-departure warnings for staff and standardized circuitry. In the prior art, patent CN116443075A discloses an audible and visual alarm method and system based on an automated boarding platform in a depot, relating to the field of fully automated unmanned rail transit technology. This invention, by setting up an audible and visual alarm device and an audible and visual alarm relay, sends the information from the signal system controlling the audible and visual alarm to the device via the relay. The device can then trigger an audible and visual alarm based on the signal system's determination, alerting personnel at the boarding platform to the presence of unmanned trains entering or exiting the corresponding track, thus protecting personnel safety to some extent. Furthermore, the automatic warning and protection achieved through relay information logic simplifies the structure of the boarding platform protection device. Since depots often have numerous tracks, this invention can automatically trigger audible and visual alarms for the corresponding tracks, avoiding safety risks caused by personnel fatigue, negligence, or communication errors.

[0003] The aforementioned audible and visual alarm method and system disclosed in the patent have the following drawbacks: 1. Although the use of audible and visual alarms and audible and visual alarm relays to implement alarms has been disclosed, the relevant circuit design and combination are lacking, which cannot improve the efficiency of drawing design and will occupy a lot of cabinet space.

[0004] 2. Each audible and visual alarm relay corresponds to an audible and visual alarm device. That is, each audible and visual alarm device requires a separate audible and visual alarm relay for individual control. In actual use, the field conditions are complex and a large number of audible and visual alarm devices are needed. If each audible and visual alarm device is equipped with its own audible and visual alarm relay, a large number of audible and visual alarm relays will be required. On the one hand, this increases the cost of audible and visual alarm relays, and on the other hand, a large number of audible and visual alarm relays will occupy a large amount of cabinet space. Summary of the Invention

[0005] To overcome the shortcomings of the existing technology, this invention discloses an audible and visual alarm circuit and its standardized assembly for safety protection in vehicle depot parking lots. This invention combines an audible and visual alarm system with a signaling system by designing a train positioning-based audible and visual alarm circuit and assembly. The train positioning function of the signaling system activates the audible and visual alarm devices in the corresponding areas of the train, thus providing additional safety protection for staff. Furthermore, the audible and visual alarm relay and circuit breaker are combined into a standardized audible and visual alarm assembly. The connection points of the circuit breaker and the audible and visual alarm relay are allocated according to a specific pattern, modularizing the standardized assembly, achieving reusability, improving design efficiency, and maximizing cabinet space utilization.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides an audible and visual alarm circuit for safety protection of a vehicle depot parking lot, comprising an audible and visual alarm device, an audible and visual alarm relay, and an audible and visual alarm circuit breaker connected in series. The audible and visual alarm is installed at the boarding platform of the track to warn of the arrival or departure of a train. The boarding platform can be accessed to one track on one side or two adjacent tracks on both sides. When access to one track on one side is available, the audible and visual alarm warns the relevant personnel on that track that a train is arriving or departing. When access to two adjacent tracks on both sides is available, the audible and visual alarm warns the relevant personnel on those two adjacent tracks that a train is arriving or departing. The audible and visual alarm relays are installed in the relay cabinet. Each audible and visual alarm relay corresponds to a different track and controls all audible and visual alarms at the boarding platform on one or both sides of the corresponding track to sound an alarm. When the boarding platform can reach a track on one side and the audible and visual alarm at the boarding platform sounds an alarm for that track, the audible and visual alarm relay corresponding to that track controls one audible and visual alarm at its boarding platform to sound an alarm. When the boarding platform can reach two adjacent tracks on both sides and the audible and visual alarms at the boarding platform sound an alarm for both adjacent tracks, the two audible and visual alarm relays corresponding to the two adjacent tracks are connected in parallel to jointly control one audible and visual alarm at its boarding platform to sound an alarm. The audible and visual alarm circuit breaker is installed in the relay cabinet and corresponds one-to-one with the audible and visual alarm. Several audible and visual alarm relays and several audible and visual alarm circuit breakers are combined in the relay cabinet to form a fixed combination of audible and visual alarms.

[0010] Preferably, the contacts of the audible and visual alarm relay are inserted into the alarm circuit of the audible and visual alarm device. The state of the contacts of the audible and visual alarm relay controls the on / off state of the alarm circuit of the audible and visual alarm device. Under normal conditions, the signal system drives the audible and visual alarm relay to be energized and pulled up, and the audible and visual alarm device does not work. Under alarm conditions, the signal system drives the audible and visual alarm relay to be de-energized and dropped, and the audible and visual alarm device works.

When access to two adjacent tracks on both sides is possible, the audible and visual alarm will alert the relevant personnel on those two adjacent tracks that a train is entering or leaving. The audible and visual alarm relays are connected in series with audible and visual alarm circuit breakers. Each audible and visual alarm relay corresponds to a different track and controls all audible and visual alarms at the boarding platform on one or both sides of the corresponding track to sound. When the boarding platform can reach a track on one side and the audible and visual alarm at the boarding platform sounds for that track, the audible and visual alarm relay corresponding to that track controls one audible and visual alarm at its boarding platform to sound, and the audible and visual alarm relay corresponding to that track corresponds to one audible and visual alarm circuit breaker. When the boarding platform can reach two adjacent tracks on both sides and the audible and visual alarms at the boarding platform sound for both adjacent tracks, the two audible and visual alarm relays corresponding to the two adjacent tracks are connected in parallel to jointly control one audible and visual alarm at its boarding platform to sound, and the two audible and visual alarm relays correspond to one audible and visual alarm circuit breaker.

[0021] The following will provide a clear and complete description of the concept, specific structure, and technical effects of the present invention in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention.

[0022] Example 1 This embodiment is achieved through the following scheme: 1) The automated area of ​​the depot parking lot is generally the storage area, which is divided into front end, middle end and back end. Generally, setting up sound and light alarms in the above three places can cover the sound and light alarm range of the storage area.

[0023] 2) In the automated area of ​​the depot parking lot, boarding platforms are generally set up at the front end, middle end and back end. Therefore, the audible and visual alarms are set up at the boarding platforms. The audible and visual alarms are named SGX, with X starting from 1.

[0024] 3) The MLX13 AC-powered audible and visual alarm is used. It is powered by AC220V and the operating current is less than 100mA. There are three alarm modes: audible and visual synchronization, audible and visual delay, and audible alarm. This project adopts the audible and visual delay alarm mode. That is, after the alarm circuit of the alarm is turned on, the audible and visual alarm parts of the alarm will start alarming at the same time, but the audible alarm will turn off after a period of time (which can be set), and only the visual alarm will be turned on.

[0025] 4) Audible and visual alarm relay drive circuit: Each track in the automated depot / section is equipped with an audible and visual alarm relay. The signal system determines whether to drive the audible and visual alarm relay based on the train positioning function.

[0026] 5) Audible and visual alarm circuit: The contact conditions of the audible and visual alarm relay are integrated into the alarm circuit of the audible and visual alarm. The on / off state of the alarm circuit is controlled by the contact status of the audible and visual alarm relay. According to the fail-safe principle, the audible and visual alarm relay is energized and activated under normal signal conditions, and the audible and visual alarm does not operate.

[0027] 6) The audible and visual alarm relays are installed in the audible and visual alarm combination in the relay cabinet. They are named according to the track name. The abbreviation of the audible and visual alarm relay is SGBJ. For example, the audible and visual alarm name corresponding to 1AG is 1AG-SGBJ. The type of audible and visual alarm relay is a polarized relay, the model is JPXC-1000, the number of contacts is 8 groups, and the contact capacity is 1A.

[0028] 7) Each audible and visual alarm is equipped with a separate circuit breaker to control the power supply of the audible and visual alarm. The circuit breaker is installed in the audible and visual alarm assembly in the relay cabinet.

[0029] 8) Combine the audible and visual alarm relays with the circuit breakers to form a standardized audible and visual alarm combination. The connection points between the circuit breaker and the SGBJ are allocated according to a certain pattern, and the standardized combination is modularized.

[0030] Compared with existing technologies, the above technical solution includes the following innovations and beneficial effects (advantages): 1. In the above schemes 1) and 3), by setting up audible and visual alarm devices, a combination of sound alarm and light alarm is used to provide protection for the personal safety of workers in the automated area of ​​the depot parking lot.

[0031] 2. Scheme 2) above improves the practicality of the equipment by installing an audible and visual alarm at the boarding platform, achieving the maximum protection effect with the least amount of equipment.

[0032] 3. In scheme 4) above, the train track serves as the basis for train positioning in the signaling system. Each track within the automated area is matched with a corresponding audible and visual alarm relay, and the train positioning information is transmitted to the signaling system through the relay status information. Using relays to transmit information offers high safety and reliability, and is easy to interface with.

[0033] 4. In the above scheme 5), the on / off state of the alarm circuit of the audible and visual alarm is controlled by the contact state of the audible and visual alarm relay. In addition, the relay is set to be normally energized and pulled up, and the audible and visual alarm does not work. When the relay fails and loses power, it will also turn on the alarm circuit of the audible and visual alarm, which conforms to the fail-safe principle. Even in the event of a fault, it still provides a warning to the operator and increases the safety of the circuit.

[0034] 5. In the above scheme 6), the JPXC-1000 relay with 8 sets of contacts is selected. With a large number of contacts, when a track corresponds to multiple sound and light alarms, the same relay can be reused, which improves the practicality and uniqueness of the scheme.

[0035] 6. Scheme 8) above: Combine the audible and visual alarm relay with the circuit breaker to form a fixed combination of audible and visual alarm. The connection points of the circuit breaker and SGBJ in the combination are allocated according to the rules. The fixed combination is modularized to realize the reusability of the fixed combination, improve the efficiency of drawing design and realize the utilization rate of cabinet space.

[0036] Example 2 like Figure 1 , 2 As shown in the depot and parking lot, the audible and visual alarms in the automated depot / section are only installed in the parking inspection depot (hereinafter referred to as the depot area) of the automated area. The audible and visual alarms are installed at the front, middle and rear boarding platforms of the automated depot / section.

[0037] Step 1: Name the audible and visual alarms SGX, with X numbered starting from 1; Step 2, according to Figure 3 The schematic diagram of the MLX3 AC-powered audible and visual alarm clearly defines the alarm principle and power supply of the audible and visual alarm, providing input conditions for the alarm circuit of the audible and visual alarm. Step 3: Integrate the audible and visual alarm system with the signaling system. Activate the audible and visual alarms in the corresponding area of ​​the train using the train positioning function of the signaling system. Figure 4 The circuit shown is as follows. When the train fails to enter the section corresponding to the audible and visual alarm, the signal system interlocks to determine that the audible and visual alarm relay for the corresponding section remains activated, and the audible and visual alarm does not activate. Step 4: Each track within the automated depot / section is equipped with a corresponding audible and visual alarm relay. The signaling system determines whether to activate the audible and visual alarm relay based on the train's positioning. Figure 5 The circuit shown is as follows: When the train enters the corresponding section, the audible and visual alarm relay drops, the audible and visual alarm circuit is turned on, and the audible and visual alarm starts to sound and light. After a certain delay, the sound alarm stops, but the visual alarm continues to sound.

[0038] Step 5: After the train has fully entered the parking track, the signal system interlocking drive re-energizes the audible and visual alarm relay, and the audible and visual alarm stops. Figure 4 The circuit shown; Step 6: Based on the layout of different vehicle depot parking lot audible and visual alarms and boarding platforms, find patterns and design a standardized combination of audible and visual alarms. Step 7: Locate the correspondence between the audible and visual alarm and the track section. The correspondence between the audible and visual alarm (circuit breaker) and the track section is either one-to-one or one-to-two, mainly depending on whether the boarding platform can access one or two tracks. The correspondence is indicated by arrows on the boarding platform, such as... Figure 6As shown. SG1 has a circuit connection only with 2AG-SGBJ. This type of associated one-to-one audible and visual alarm circuit breaker and SGBJ is defined as a Class A combination unit. SG3 has a circuit connection with both 2AG-SGBJ and 3AG-SGBJ. Either 2AG-SGBJ or 3AG-SGBJ can trigger the alarm condition of SG3. This type of associated one-to-two audible and visual alarm circuit breaker and SGBJ is defined as a Class B combination unit. Class A and Class B combination units constitute audible and visual alarm sets. Based on the setting rules of field / section audible and visual alarms, simplified audible and visual alarm standard combinations are formed. Multiple sets can be placed in one standard combination. The contacts of SGBJs in the set are designed and correspond one-to-one with the corresponding circuit breakers according to the rules. The wiring within the set is properly configured inside the combination (similar to standard combinations), greatly reducing the design and field workload, reducing the complexity of field wiring, and saving space in the combination cabinet. According to the pattern, the standard combinations of sound and light alarms are mainly divided into four types, namely SGBJ1~SGBJ4 standard combinations. This article mainly introduces the design ideas of the standard combinations.

[0039] Step 8, Design the SGBJ1 standard combination: The SGBJ1 combination is suitable for situations where one audible and visual alarm (circuit breaker) corresponds to one or two audible and visual alarm relays (sections), such as... Figure 7 , Figure 8 As shown (the top left diagram is the schematic diagram, in which the connection points between SGBJ and circuit breaker have been assigned; the top right diagram is a layout example; the bottom diagram is a design example of the relay type table; similar examples will be given later). In the SGBJ1 combination, one circuit breaker and one / two SGBJs form two sets respectively. This combination can accommodate 6 circuit breakers and 6 SGBJs. The circuit breaker and SGBJ contacts within each set are already configured within the combination.

[0040] Step 9, Design the SGBJ2 standard combination: The SGBJ2 combination is suitable for situations where two audible and visual alarms (circuit breakers) correspond to two audible and visual alarm relays (sections), such as... Figure 9 As shown. The wiring between the circuit breaker and the audible and visual alarm relay contacts of the two audible and visual alarms in the same storage area is implemented within the combination, which is a wiring kit. One SGBJ2 combination can hold 3 of the above kits.

[0041] Step 10, Design the SGBJ3 standard combination: The SGBJ3 combination is suitable for situations where there are three adjacent storage areas, with five audible and visual alarm devices (circuit breakers) corresponding to three audible and visual alarm relays (sections), such as... Figure 10 As shown. In this case, the circuit breakers for the five audible and visual alarms and the wiring for the three audible and visual alarm relays are integrated within the assembly, forming a wiring kit. One SGBJ3 assembly can house one of these kits.

[0042] Step 11, Design SGBJ4 standard combination: SGBJ4 combination is used to place a small number of special sets and sets that cannot be placed in other combinations. The specific situation depends on the actual situation of each project site / section.

[0043] Special Set 1: A configuration where four audible and visual alarms (circuit breakers) correspond to three audible and visual alarm relays, such as... Figure 11 As shown in the example, the set consisting of the audible and visual alarm relays corresponding to 1AG, 2AG, and 3AG, and the circuit breakers SG2, SG3, SG5, and SG6 is placed in the SGBJ4 combination.

[0044] Special Set Two: Two audible and visual alarms (circuit breakers) correspond to one audible and visual alarm relay, such as... Figure 12 As shown, only the audible and visual alarm relays corresponding to 2BG are placed in the SGBJ4 combination. The audible and visual alarm relays and circuit breaker sets of the audible and visual alarm devices corresponding to 1BG and 3BG can be classified as SGBJ1 combinations, and the corresponding circuit breakers and relays are placed in the SGBJ1 combination. The empty spaces in the SGBJ4 combination can also be used to place equipment that cannot be placed in other combinations.

[0045] Step 12, SGBJ Contact Allocation Principles for Standardized Combinations: The connection contacts between the circuit breakers and SGBJs in a set should also be allocated according to a pattern to achieve the reusability of the standardized combination and facilitate drawing design. Special attention should be paid to the relay contact allocation, especially for sets with multiple circuit breakers corresponding to a small number of relays. For example, in SGBJ1, it is specified that the 1 / 2 contact of the SGBJ is used for wiring with the circuit breaker; in SGBJ2, the same circuit breaker has a wiring relationship with two SGBJs, and these two SGBJs are wired with contacts 3 / 4 and 5 / 6 respectively; the contact usage pattern for SGBJ3 is a combination of SGBJ1 and SGBJ2. Figure 10 In the schematic diagram, the first SGBJ corresponding to the 2nd and 4th circuit breakers is wired with a 3 / 4 contact, and the second SGBJ is wired with a 5 / 6 contact. The SGBJs corresponding to the 1st, 3rd, and 5th circuit breakers are all wired with a 1 / 2 contact. The case for SGBJ4 is different from the previous three combinations. Figure 11 In the schematic diagram, the first and third SGBJs are connected to the circuit breaker on the left side of the track using 3 / 4 contacts and to the circuit breaker on the right side of the track using 5 / 6 contacts. The second SGBJ's 8 contacts are to be connected to 4 circuit breakers respectively, and the circuit breakers of the audible and visual alarms 1 to 4 are wired using 5 / 6, 3 / 4, 7 / 8, and 1 / 2 contacts respectively.

[0046] This audible and visual alarm circuit and its standardized assembly were applied to the depot and parking lot of the Chengdu Metro Line 9 signaling project. It combines the audible and visual alarm system with the signaling system, and activates the audible and visual alarms in the corresponding areas of the train based on the train positioning function of the signaling system. The audible and visual alarms provide additional protection for the personal safety of the staff. Actual testing has proven that it can meet the on-site requirements, effectively avoid the safety hazards caused by manual operation, improve the efficiency of drawing design, and save cabinet space.

[0047] The embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalents or substitutions are all included within the scope defined by the claims of the present invention.
