[0052] Before elaborating on each embodiment of the present invention in detail, the core inventive concept of the present invention is summarized and elaborated in detail through the following several embodiments.

[0053] The purpose of the present invention is to solve the problems existing in the prior art and to seek to design a locomotive brake cylinder intelligent control module, which integrates the brake cylinder pre-control control unit and the brake cylinder relay valve unit into the same module, with a compact structure and easy installation, thereby improving the degree of integration; the brake cylinder relay valve adopts a double diaphragm plate double pre-control relay valve, and the two pre-controls are redundant with each other, thereby improving the reliability of the relay valve and the safety of the braking system; the brake cylinder control module is used to make the average pipe control module redundant, and at the same time, the brake cylinder control, train pipe control and average pipe control are integrated into one, thereby improving the redundancy, reliability and safety of the system.

[0054] In order to achieve the above purpose, the technical solution adopted by the present invention is to design a locomotive brake cylinder intelligent control module, which responds to the locomotive train pipe pressure and outputs the locomotive brake cylinder pressure, thereby achieving the braking and release of the locomotive. Figure 1 As shown, the control module includes an intelligent control unit Z1, a junction box Z3, and an integrated valve Z2. Figure 2 As shown, the integrated valve Z2 includes a total air filter 01, an air charging solenoid valve 04, an exhaust solenoid valve 05, a distribution valve switching solenoid valve 08, a distribution valve switching air control valve 09, a single slow solenoid valve 10, a relay valve 13, a balanced standby switching solenoid valve 15, a first shrink plug 03, a second shrink plug 06, a first air inlet 09-1 of the air control valve, a second air inlet 09-2 of the air control valve, an air outlet 09-3 of the air control valve, a control port 09-4 of the air control valve, a first pre-control port 13-1 of the relay valve, a second pre-control port 13-2 of the relay valve, an air inlet 13-3 of the relay valve, and an air outlet 13-4 of the relay valve. -4, the first main air interface 101, the second main air interface 102, the air brake valve pressure interface 103, the average pipe pressure interface 106, the brake cylinder pressure interface 107, the train pipe pressure interface 108, the equalization control backup interface 104, the average pipe control backup interface 105, the automatic brake pre-control pressure measuring point C02.01, the brake cylinder pressure measuring point C02.02, the automatic brake pre-control pressure sensor 07, the brake cylinder pressure sensor 02, the train pipe pressure sensor 14; the external network interface D01 and the external network interface D02 are integrated on the junction box Z3.

[0055] like Figure 3As shown, the first total air interface 101 and the second total air interface 102 are connected to the total air pressure of the locomotive to provide an air source for the brake cylinder intelligent control module; the air inlet of the charging solenoid valve 04 is installed with a first shrink plug 03, and is connected to the air outlet of the total air filter 01; the air outlet of the charging solenoid valve 04 is connected to the air inlet of the exhaust solenoid valve 05, and is also connected to the first air inlet 09-1 of the air control valve, and the exhaust port of the exhaust solenoid valve 05 is connected to the atmosphere; the air control valve control port 09-4 is connected to the air outlet of the distribution valve switching solenoid valve 08, and the air inlet of the distribution valve switching solenoid valve 08 is connected to the air outlet of the total air filter 01; the second air inlet 09-2 of the air control valve is connected to the air brake valve pressure interface 103; the air control valve outlet 09- 3 is connected to the first air inlet of the single-slow solenoid valve 10, the second air inlet of the single-slow solenoid valve 10 is connected to the first pre-control port 13-1 of the relay valve, and the exhaust port of the single-slow solenoid valve 10 is connected to the atmosphere; the second pre-control port 13-2 of the relay valve is connected to the average pipe pressure interface 106, the air inlet 13-3 of the relay valve is connected to the second total air interface 102, and the air outlet 13-4 of the relay valve is connected to the brake cylinder pressure interface 107, the air outlet of the charging solenoid valve 04 is also connected to the balancing standby switching solenoid valve 15 and the average pipe control standby interface 105, and the other two ports of the balancing standby switching solenoid valve 15 are respectively connected to the balancing control standby interface 104 and the atmosphere, and the train pipe pressure interface 108 is connected to the train pipe pressure sensor 14.

[0056] The main air filter 01 filters the compressed air entering the charging solenoid valve 04 and the distribution valve switching solenoid valve 08.

[0057] The distribution valve switching solenoid valve 08 controls the switching action of the distribution valve switching air control valve 09.

[0058] The relay valve 13 amplifies the flow rate of the larger pressure between the first pre-control port 13-1 and the second pre-control port 13-2 of the relay valve and outputs the amplified pressure through the relay valve outlet 13-4.

[0059] The intelligent control unit Z1 receives network signals from other network nodes such as the locomotive brake controller, the train pipe control module, and the individual control module through the external network interface D01 and the external network interface D02, collects pressure signals from the automatic brake pre-control pressure sensor 07, the brake cylinder pressure sensor 02, and the train pipe pressure sensor 14, and controls the gain and loss of power of the charging solenoid valve 04, the exhaust solenoid valve 05, the distribution valve switching solenoid valve 08, and the single slow solenoid valve 10;

[0060] Integrated valve Z2 integrates and installs all valves in the same valve body.

[0061] Junction box Z3 is used for cable arrangement and protection between sensors, solenoid valves and intelligent control unit Z1.

[0062] Under normal circumstances, the intelligent control unit Z1 controls the action of the charging and discharging solenoid valves 04 and 05 according to the train pipe pressure collected by the train pipe pressure sensor 14, generates brake cylinder pre-control pressure, and switches the air control valve 09 and the single buffer solenoid valve 10 through the distribution valve, and then outputs the brake cylinder pressure to the brake cylinder pressure interface 107 through the flow amplification effect of the brake cylinder relay valve 13. The brake cylinder pre-control air cylinder interface 109 is externally connected to the brake cylinder pre-control air cylinder B00.05 to play a buffering role.

[0063] When the intelligent control unit Z1 receives a separate release command from the brake controller or an air-electric interlock signal from the locomotive, the single release solenoid valve 10 is energized to exhaust the pre-control pressure of the relay valve 13, thereby exhausting the brake cylinder pressure of the brake cylinder pressure interface 107.

[0064] When the locomotive is in the coupled locomotive mode, the pressure from the average pipe of the main locomotive can be amplified through the average pipe pressure interface 106 and the relay valve 13 to output the brake cylinder pressure. At this time, the single buffer solenoid valve 10 is in the energized state.

[0065] When the brake cylinder control module fails, the distribution valve switching solenoid valve 08 automatically guides the power-off control distribution valve switching valve to operate, and the individual control module average pipe pressure from the average pipe pressure interface 106 and the mechanical distribution valve pressure from the air brake valve pressure interface 103 simultaneously control the brake cylinder relay valve to achieve redundant control of the brake cylinder.

[0066] When the intelligent control unit Z1 receives the fault information and backup request instruction of the train pipe control module, Z1 controls the balancing backup switching solenoid valve 15 to be energized, so that the distribution valve switching solenoid valve 08 loses power, so that the output pressure of the charging and exhaust solenoid valve 04 and the exhaust solenoid valve 05 is output to the train pipe control module through the balancing backup switching solenoid valve 15 and the balancing control backup interface 104, controls the balancing air cylinder pressure, and then realizes redundant control of the train pipe pressure. At this time, the separate control module average pipe pressure from the average pipe pressure interface 106 and the mechanical distribution valve pressure from the air brake valve pressure interface 103 simultaneously control the brake cylinder pressure.

[0067] When the intelligent control unit Z1 receives the fault information and backup request instruction of the separate control module, the distribution valve switching solenoid valve 08 is de-energized, and the output pressure of the charging and exhaust solenoid valve 04 and the exhaust solenoid valve 05 is output to the separate control module through the average pipe control backup interface 105 to control the average pipe relay valve, thereby realizing redundant control of the average pipe pressure. At this time, the average pipe pressure of the separate control module from the average pipe pressure interface 106 and the mechanical distribution valve pressure from the air brake valve pressure interface 103 simultaneously control the brake cylinder pressure.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of protection of the invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the scope of protection of the present application. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the attached claims.
