Description

Technical Field

[0001] The present invention relates to the field of personnel protection, and in particular to a personnel protection design method based on a full electronic interlocking system. Background Art

[0002] The personnel protection function of the existing computer interlocking system is achieved through the internal logic of the computer interlocking system and the peripheral safety relay circuit. The internal logic of the computer interlocking system realizes the input and output acquisition drive; the peripheral safety relay circuit realizes circuit excitation and self-protection, which is implemented in the combination cabinet.

[0003] The existing technology requires a combination cabinet due to the use of safety relays, which occupies a large indoor space; since self-protection and excitation are achieved through hard-wired connections of relays, the combination cabinet has many wiring and hard-wire failure points, which brings great difficulties to early testing and later maintenance. Summary of the Invention

[0004] In response to the problems of complex protection methods and difficult operation and maintenance of existing technicians, the present invention provides a personnel protection design method based on a fully electronic interlocking system. It performs multi-channel dynamic acquisition through a fully electronic input board and performs multi-channel node output through a fully electronic output board, which simplifies personnel defense measures, reduces the difficulty of operation and maintenance, and prevents errors caused by mixed lines.

[0005] The following are the technical solutions of the present invention.

[0006] A personnel protection design method based on a fully electronic interlocking system includes the following steps:

[0007] Through the full electronic input board, multi-channel dynamic acquisition of civil air defense status is carried out to obtain relevant parameters;

[0008] Judge the relevant parameters and select the civil air defense mode to be executed;

[0009] When the civil air defense state is selected as the release mode, the permission signal is output, and the multi-channel node output is performed through the fully electronic output board card to control the relay coil of the platform civil air defense access control to unlock it, allowing personnel to enter the track area for operation;

[0010] When the civil defense status is selected as the normal mode, a prohibition signal is output, and multi-node output is performed through the fully electronic output board to control the relay coil of the platform civil defense access control to lock it, prohibiting personnel from entering the track area for operation.

[0011] The multi-channel dynamic data collection and multi-channel node output of the present invention improves reliability, simplifies civil defense measures, reduces operation and maintenance difficulty, and prevents errors caused by mixed lines. In addition, modular cabinets are no longer required, thus saving indoor space.

[0012] Preferably, the multi-channel dynamic acquisition of the civil air defense status is performed through the all-electronic input board to obtain relevant parameters, including:

[0013] A fully electronic input board containing at least two mutually isolated acquisition channels is used. Each acquisition channel generates a dynamic signal for reference by the other channel. When the power is turned on, if the detected signal change is consistent with the dynamic detection signal, the acquisition is considered correct.

[0014] Preferably, the steps performed by the all-electronic input board include:

[0015] The two acquisition channels of the fully electronic input board generate dynamic signals respectively. The dynamic signals are collected by the other channel after passing through different isolation units. Each acquisition channel has a double-break function. Each channel is connected to IN+ and IN-, IN+ is connected to 24V, and IN- is connected to GND. When IN+ and IN- are connected to 24V power supply, if the detected signal change is consistent with the dynamic detection signal, the acquisition is considered correct. When either IN+ or IN- is disconnected, the signal cannot be collected.

[0016] Different channels in the present invention will not affect each other, and at the same time, interference to the internal part of the board caused by the collected abnormal signals can be prevented.

[0017] Preferably, the multi-channel node output is performed by a fully electronic output board, including:

[0018] The fully electronic input board controls the relay coil by outputting a switching value, thereby realizing a relay node output. Each switching value is controlled by two channels, each including a positive and a negative end, and connected to the two ends of the corresponding relay coil. Different channels are controlled by different controllers. When both the positive and negative ends of each switching value are turned on, the conditional power supply forms a current loop in the relay coil, and the relay is attracted.

[0019] Preferably, the different channels are controlled by different controllers, including:

[0020] The controller performs a two-out-of-two vote on each of the received output instructions. If the votes are consistent, the two channel switches are turned on and output is external; if the votes of any channel are inconsistent, the corresponding channel switch will be turned off and no output is external.

[0021] Preferably, the source of collection of the relevant parameters is the civil air defense button of the integrated backup disk, which is transmitted to the fully electronic input board through the distribution cabinet.

[0022] Preferably, when the multi-path node output is performed through the all-electronic output board, the signal is output from the all-electronic output board and then passes through the distribution cabinet, the integrated backup disk and the relay coil of the civil air defense access control.

[0023] The substantial effects of the present invention include:

[0024] 1) Due to the reduction of combined cabinets, indoor space is saved;

[0025] 2) Shorten equipment debugging time and reduce the difficulty of subsequent maintenance;

[0026] 3) Improve efficiency and reduce transformation difficulty;

[0027] 4) Dynamic detection technology can eliminate errors in collecting civil air defense status caused by mixed lines;

[0028] 5) Dual-channel control output improves output reliability. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

"And / or" is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0037] The technical solution of the present invention is described in detail below with reference to specific embodiments. The embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0038] Example:

[0039] A personnel protection design method based on a fully electronic interlocking system includes the following steps:

[0040] Through the full electronic input board, multi-channel dynamic acquisition of civil air defense status is carried out to obtain relevant parameters;

[0041] Judge the relevant parameters and select the civil air defense mode to be executed;

[0042] When the civil air defense state is selected as the release mode, the permission signal is output, and the multi-channel node output is performed through the fully electronic output board card to control the relay coil of the platform civil air defense access control to unlock it, allowing personnel to enter the track area for operation;

[0043] When the civil defense status is selected as the normal mode, a prohibition signal is output, and multi-node output is performed through the fully electronic output board to control the relay coil of the platform civil defense access control to lock it, prohibiting personnel from entering the track area for operation.

[0044] Figure 1 This is a simplified flow chart of the civil air defense logic algorithm of this embodiment. Figure 2 This is a schematic diagram of system acquisition and driving according to an embodiment of the present invention, wherein the activation and cancellation process of the civil air defense function is as follows:

[0045] 1. Operate the civil air defense knob on the integrated backup panel (IBP) to the "enabled" state. After 80 seconds, the civil air defense light on the integrated backup panel will turn red, and the platform civil air defense permission light will light up. The platform civil air defense access control will be unlocked and you can enter the track area for construction work.

[0046] 2. When the construction work is completed, on the integrated backup panel, operate the civil defense knob to "normal" and reset the "master reset button" to release the civil defense. At this time, the indoor IBP panel civil defense light and the platform civil defense permission light will go out, the platform civil defense prohibition light will be on, and the platform civil defense door will be unlocked, prohibiting personnel from entering the track area for operation.

[0047] 3. When the abnormal situation cannot be restored after the civil air defense is activated, the bypass civil air defense function can be started by activating the "civil air defense bypass" knob on the IBP panel to avoid affecting the train operation.

[0048] Among them, the source of collection of relevant parameters is the civil defense button of the integrated backup disk, which is transmitted to the fully electronic input board through the distribution cabinet.

[0049] When multi-channel node output is performed through a fully electronic output board, the signal is output from the fully electronic output board and then passes through the distribution cabinet, the integrated backup disk and the relay coil of the civil air defense access control.

[0050] The multi-channel dynamic acquisition and multi-channel node output of this embodiment improves reliability, simplifies civil defense measures, reduces operation and maintenance difficulties, and prevents errors caused by mixed lines. In addition, modular cabinets are no longer required, thus saving indoor space.

[0051] Among them, multi-channel dynamic acquisition of civil air defense status is carried out through a full electronic input board to obtain relevant parameters, including: using a full electronic input board containing at least two mutually isolated acquisition channels, each acquisition channel generates a dynamic signal for reference by the other channel, and when the power is turned on, if the detected signal change is consistent with the dynamic detection signal, the acquisition is considered correct.

[0052] like Figure 3 The figure shows a schematic diagram of the fully electronic input board of this embodiment. The two acquisition channels of the fully electronic input board each generate dynamic signals. The dynamic signals are collected by the other channel after passing through different isolation units. Each acquisition channel has a double-break function. Each channel is connected to IN+ and IN-, with IN+ connected to 24V and IN- connected to GND. When IN+ and IN- are connected to 24V power, if the detected signal changes are consistent with the dynamic detection signal, the acquisition is considered correct. If either IN+ or IN- is disconnected, the signal cannot be collected.

[0053] Different channels in the present invention will not affect each other, and at the same time, interference to the internal part of the board caused by the collected abnormal signals can be prevented.

[0054] like Figure 4The figure shows a schematic diagram of the fully electronic output board of this embodiment. The fully electronic input board controls the relay coil by outputting a switching value, thereby realizing a relay node output. Each switching value is controlled by two channels, each including a positive and a negative terminal, and connected to the two ends of the corresponding relay coil. Different channels are controlled by different controllers. Channel 1 controls the on / off of the positive terminal 24V conditional power supply of the switching value, and channel 2 controls the on / off of the negative terminal GND conditional power supply. When both the positive and negative terminals of each switching value are turned on, the conditional power supply forms a current loop in the relay coil, and the relay is attracted.

[0055] If either channel 1 or channel 2 is disconnected, the output of that channel will be impossible. The controller will vote on the received output instructions. If the votes are unanimous, the two channel switches will be turned on and output will be output; if the votes of any channel are inconsistent, the corresponding channel switch will be disconnected and no output will be output.

[0056] The fully electronic interlocking personnel protection design eliminates peripheral relay circuits for "self-protection" and "excitation" functions. Instead, a fully electronic input board records the status of the integrated backup panel (IBP) for the air defense buttons and activates the peripheral air defense indicator lights. The excitation and self-protection functions are handled by computer interlocking software logic. The fully electronic interlocking system records the status of the air defense buttons and activates the indicator lights via the distribution cabinet and the IBP, rather than the modular cabinet. This reduces the equipment footprint and lowers the space requirements for the equipment room.

[0057] Therefore, the substantial effects of this embodiment include:

[0058] 1) Due to the reduction of combined cabinets, indoor space is saved;

[0059] 2) Shorten equipment debugging time and reduce the difficulty of subsequent maintenance;

[0060] 3) Improve efficiency and reduce transformation difficulty;

[0061] 4) Dynamic detection technology can eliminate errors in collecting civil air defense status caused by mixed lines;

[0062] 5) Dual-channel control output improves output reliability.
