Description

Technical Field

[0001] The present invention relates to the field of intelligent control of a driver's cab, and in particular to an intelligent control circuit and method for auxiliary equipment in a train driver's cab. Background Art

[0002] The driver's cab of a rail transit train is equipped with non-vehicle control components such as interior lighting, electric fans and wipers. If the driver, co-driver or additional passengers need to turn on relevant components during driving, they need to operate the corresponding switches or keys, which poses a risk of affecting normal driving or accidental touch.

[0003] The existing technology has proposed civilian smart switches, smart lighting equipment, smart curtains, etc.: they can realize home intelligence through mobile terminal devices, voice, etc. However, they rely on the Internet or home LAN, and the equipment cannot be controlled after the network is interrupted or the power of the home gateway is disconnected. The circuit capacity of civilian equipment is low, and the smart switch cannot drive high-current equipment. The device terminal needs to add a network communication controller, and the cost of traditional equipment transformation increases. It relies on the smart control platform built by the manufacturer, with poor scalability and difficulty in compatibility of devices on different platforms.

[0004] The prior art has proposed intelligent control circuits for civilian cars: civilian cars are equipped with display screens, integrated processors, etc., and the on-board components can be controlled by clicking on the display screen, voice control, etc. However, the realization of intelligent control of vehicle-mounted equipment mainly relies on the integrated processor (CPU) to collect external instructions and send commands. The components are highly integrated, but fault location is difficult, and maintenance can only be done by replacing the entire device. The control of auxiliary equipment of some civilian cars is completely dependent on the vehicle computer. The physical buttons are canceled or the physical button signals are only input into the vehicle computer. When the vehicle computer power is disconnected or the communication is interrupted, the equipment cannot be controlled. Since the entire intelligent realization is based on the vehicle computer, the intelligent control circuit interface has poor versatility and can only match the corresponding CPU.

[0005] The existing technology proposes that some rail trains have voice recording and intelligent driving functions. The voice recording function means that the train driver's cab has a voice recording function and can record the driver's cab. Intelligent driving means that the train can realize driving functions such as wake-up, operation and shutdown according to ground signals or remote operation. Intelligent driving enables the train group to use the on-board microcomputer network circuit and central control unit to complete operations such as starting, speed limit operation and precise parking in specific application scenarios, thereby improving driving intelligence. However, the train's on-board recording equipment can only record and cannot realize intelligent operations such as voice control. Intelligent driving focuses on the automatic control of the start and stop operation of the train, and performs operation control through the on-board central control unit, and cannot realize the control of auxiliary equipment in the driver's cab.

[0006] Therefore, it is urgent to control the auxiliary equipment in the driver's cab without changing the existing traditional equipment in the driver's cab. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0022] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0023] The present invention proposes a circuit for intelligent control of auxiliary equipment in the train driver's cab. Figure 1 , Figure 2 and Figure 3 ,include: A first positive pole of a power supply, a second positive pole of a power supply, a start relay, a shut-down relay, a self-reset switch, an intelligent control start switch, and an intelligent control shut-down switch; The first positive electrode of the power supply is connected to the self-resetting switch, the self-resetting switch is respectively connected to the start relay and the stop relay, and the load circuit is connected in parallel to the negative electrode of the power supply; The second positive pole of the power supply is connected to the intelligent control on switch and the intelligent control off switch, the intelligent control on switch is connected to the start relay, the intelligent control off switch is connected to the off relay, and the load circuit is connected in parallel to the negative pole of the power supply.

[0024] The block diagram of the present invention is as follows Figure 2 The figure shows a block diagram of the intelligent control method for auxiliary equipment in the driver's room. The boxes are equipment, and the connections between the boxes are electrical line connections.

[0025] Manual control switch: The switches of various devices installed on the operating console of the driver's cab, including push button switches, lever switches, and universal switches. To match the intelligent control function, all switches are self-resetting switches.

[0026] Intelligent triggering: A device that can provide node switches for accessing circuits, such as microcomputers, voice modules, and sensors.

[0027] Intelligent control circuit: The circuit connected to the manual switch and the intelligent trigger switch, including relays, diodes and other components, to realize the control of the equipment in the driver's room.

[0028] Driver's cab auxiliary equipment: such as cab lights, sunshades, electric fans and other non-vehicle control parts.

[0029] The present invention proposes an intelligent control method for auxiliary equipment in a train driver's cab, so that the equipment can be controlled by voice, sensors, etc., which changes the disadvantage that the equipment in the train driver's cab can only be controlled manually, reduces the driver's non-driving operations during driving, and improves the intelligence level of the train driver's cab.

[0030] The control method and circuit of the present invention are completely composed of electrical wires and electrical components. They do not require additional network communication and gateway equipment, nor do they require special integrated circuits or chips. They have high stability and strong maintainability, and are suitable for various application scenarios of rail trains such as multiple tunnels, high cold and high altitudes, etc.

[0031] The realization of the intelligent control in the present invention does not change the characteristics of the original manual switch control. In the case of failure of intelligent equipment such as a microcomputer, a sensor, etc., the function can still be realized through manual control, and the circuit reliability is high.

[0032] The intelligent control access in the present invention only requires a set of node switch signals. As long as the intelligent device can provide node switches, it can be connected to the circuit. There is no need for preconditions such as network adaptation and interface matching. It has a high degree of adaptability to intelligent devices and the entire circuit has strong expandability.

[0033] Compared with the civilian intelligent control method, the equipment included in the present invention has strong adaptability to rail transit products. The method and circuit of the present invention fully consider the layout and wiring characteristics of the train driver's cab equipment, and all use common electrical components, which are low in cost and easy to inspect and maintain.

[0034] In some embodiments, see Figure 1 , Figure 2 and Figure 3 , the first positive electrode of the power supply is used to supply power for manual control; and The second positive pole of the power supply is used to power the intelligent control.

[0035] Power supply: The working power supply for equipment provided by the train. Power supply I+ refers to the power allocated to traditional manual switch control, and power supply II+ refers to the power allocated to intelligent control.

[0036] After a long period of application and verification, the stability and reliability of traditional manual switches have been widely recognized. In the absence of interference from complex electronic equipment, manual switches can ensure a stable supply of power. The operation of manual switches is simple and intuitive, and the manufacturing cost of traditional manual switches is relatively low, so the distribution method of power I+ has more cost advantages.

[0037] Intelligent control allows users to control the power switch through microcomputers, which greatly improves the convenience of use. Users can adjust the power status at any time according to their needs to achieve more flexible management.

[0038] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The intelligent control on switch and the intelligent control off switch are used to provide node signals.

[0039] Intelligent control on / off switch: A node switch used to realize intelligent control. It can be an intelligent device such as a microcomputer, sensor or voice control module that can provide node signals. Since it is a physical switch, it does not require network or integrated circuit adaptation and has strong versatility.

[0040] Physical node switches can quickly respond to instructions from intelligent devices such as microcomputers, sensors or voice control modules to achieve instant opening or closing of switches. Since they are not dependent on networks or integrated circuits, node switches reduce the risk of control failure due to network failures or integrated circuit damage. Their physical properties give them higher stability and reliability in the face of harsh environments or power fluctuations. Physical switches usually have standardized interfaces and simple installation processes, without the need for complex network configuration or integrated circuit adaptation. This reduces installation costs and makes maintenance easier and faster. The strong versatility makes node switches compatible with many different types of intelligent devices. Whether it is a microcomputer, sensor or voice control module, as long as it can provide a node signal, it can be connected and controlled with this switch.

[0041] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The start relay and the shut down relay include a start relay normally open contact and a shut down relay normally closed contact.

[0042] Start and stop relay: an electromagnetic relay used to realize circuit control functions. The relay contains normally open and normally closed contacts, which are used for circuit control interlocking. Relays adapted to this circuit are widely used in the field of rail vehicles. The present invention can realize the joint control of equipment by intelligent and manual switches through the design of external circuits without modifying the traditional auxiliary equipment in the driver's cab, and the manual switch has a high priority, that is, if the manual switch and intelligent control trigger the intelligence at the same time, only the corresponding instructions of the manual switch will be executed.

[0043] In the unpowered state, the normally open contact is in the open state. When the relay is powered on, the contact closes to connect the circuit. This makes the normally open contact very useful in scenarios where the start of electrical appliances needs to be controlled. In contrast to the normally open contact, the normally closed contact is in the closed state when the power is not supplied. When the relay is powered on, the contact opens to disconnect the circuit. Normally closed contacts play an important role in the safety protection of circuits. Through the normally open and normally closed contacts of the relay, the interlocking and self-locking functions of the circuit can be realized, thereby preventing circuit failure or equipment damage caused by misoperation. The reliability and stability of the relay contacts make the circuit interlocking circuit more stable and reliable. Even in harsh environments or power fluctuations, the relay can maintain its normal function, thus ensuring the normal operation of the circuit interlocking circuit.

[0044] Relays usually have standardized interfaces and connection methods, which makes them easy to integrate with other circuit components or circuits. Whether it is a microcomputer, sensor or other intelligent equipment, it can be connected and controlled with the circuit interlocking circuit through relays.

[0045] In some embodiments, see Figure 1 , Figure 2 and Figure 3 , connecting a contact circuit in parallel between the self-resetting switch and the circuit of the starting relay; The contact circuit includes a normally open contact of a start relay and a normally closed contact of a stop relay.

[0046] Self-reset switch: installed on the operator's console to control the equipment in the driver's cab. Used for manual operation. In order to match intelligent control, a self-reset switch is required.

[0047] The self-reset switch can automatically return to its initial state after manual operation, without the need for the user to perform additional reset actions, thereby simplifying the operation process and improving operating efficiency. Due to its automatic reset function, the self-reset switch can reduce the risk of equipment failure or damage caused by misoperation. The self-reset switch can be seamlessly connected with the intelligent control circuit to realize a variety of intelligent functions such as remote control and timing control. By combining with the intelligent control circuit, the self-reset switch can achieve precise control of the equipment in the driver's room and improve the operating efficiency of the entire circuit. When an abnormal state occurs in the circuit (such as short circuit, overload, etc.), the self-reset switch can automatically disconnect the circuit to protect the equipment from damage.

[0048] The self-resetting switch is specially designed with high stability and reliability, and can maintain normal operation in harsh environments.

[0049] In some embodiments, see Figure 1 , Figure 2 and Figure 3 , the input of the load circuit is connected to the normally open contact of the start relay, and the output of the load circuit is connected to the negative pole of the power supply.

[0050] The train provides working power for the entire intelligent control circuit, and is divided into two independent power supplies for manual switching and intelligent control respectively. Power failure of the intelligent equipment will not affect manual control.

[0051] Manual control process: When the manual switch is set to the open position, the start relay is energized and self-locks through the circuit, the start relay's normally open contact closes, and the load starts working. When the manual switch is set to the closed position, the closing relay is energized, the closing relay's normally closed contact opens, the original self-locking circuit loses power, and the load stops working.

[0052] Intelligent control process: The intelligent control opening node is closed, the starting relay is energized, and the load is started through the self-locking circuit. The intelligent control closing node is closed, the closing relay is energized, the self-locking circuit loses power, and the load stops working.

[0053] The present invention proposes a method for applying the circuit for intelligent control of auxiliary equipment in the train driver's cab, please refer to Figure 4 ,include: S1: Obtain intelligently triggered control signals and manual signals; S2: According to the control signal, control the intelligent control on switch and the intelligent control off switch to work, and according to the manual signal, control the self-reset switch to work; S3: Based on the working status of the intelligent control opening switch and the intelligent control closing switch and the working status of the self-resetting switch, controlling the operation of the starting relay and the closing relay; S4: In response to the intelligent control process, the load operation is adjusted by starting the relay and closing the relay; in response to the manual control process, the load operation is adjusted by the start relay normally open contact and the close relay normally closed contact in the start relay and the close relay.

[0054] The present invention proposes an intelligent control method for a train driver's cab, which can control various auxiliary equipment (electric fans, lighting lamps, sunshades, etc.) in the driver's cab through a microcomputer, a voice module or a sensor on the basis of traditional manual switch control, thereby solving the shortcoming that various auxiliary equipment in the driver's cab can only be controlled by manual switches, reducing the driver's non-driving operation behavior and improving the intelligence level of the train set.

[0055] Although intelligent control circuits for equipment have been widely used in the civilian field, such as homes and civilian cars, they still have many defects that are not compatible with intelligent control of rail train equipment: The signal transmission of most civilian intelligent control circuits depends on wireless networks, Bluetooth gateways or local area networks. Some control circuits even cancel physical switches, or the switch signals are only transmitted to the gateway, which then controls the device. The above circuits cannot realize the control function when the network is interrupted or the gateway power is disconnected; In order to adapt to gateway control, traditional terminal devices also need to add corresponding network adapter modules, which increases manufacturing costs, and the compatibility of devices on different platforms is poor.

[0056] In order to adapt to the characteristics of civilian products, most intelligent control circuits use integrated circuits to control terminal equipment. The operating conditions of rail trains are harsh, and civilian standard integrated circuit boards are not applicable. In addition, the load current of motors such as train wipers and sunshades is large, which exceeds the design capacity of civilian integrated circuit boards.

[0057] The additional development of integrated circuit boards, CPUs and other control circuits is costly, and due to the characteristics of integrated circuits, failures can only be corrected by replacing the entire circuit, which is not suitable for the operation and maintenance mode of rail trains.

[0058] The present invention comprehensively considers the convenience of rail train operation and maintenance, the adaptability of existing electrical equipment interfaces, and the convenience of layout and wiring of auxiliary equipment in the driver's cab, and proposes an intelligent control circuit suitable for auxiliary equipment in the train driver's cab. The circuit can be adapted to traditional rail transit electrical components, does not require gateway or integrated circuit control, has low circuit cost and high maintainability, and has a highly versatile and expandable intelligent control interface.

[0059] In some embodiments, see Figure 4 Based on the working state of the intelligent control opening switch and the intelligent control closing switch and the working state of the self-resetting switch, the steps of controlling the operation of the starting relay and the closing relay include: In response to the intelligent control start switch closing, the start relay is energized; In response to the intelligent control shutdown switch closing, the shutdown relay is energized; In response to the self-resetting switch being in the open position, the starter relay is energized; In response to the self-resetting switch being in the OFF position, the closing relay is energized.

[0060] By intelligently controlling the opening and closing of switches, remote or timed control of the relay can be achieved without manual operation, thus improving the automation of the system. Automated control reduces the frequency of manual intervention, reduces the possibility of human error, and improves the stability and reliability of the system.

[0061] The combination of intelligent control switch and self-reset switch enables the system to select different control modes according to different needs, such as manual control, remote control, timing control, etc. This control method can adapt to different application scenarios and working environments and meet diverse control needs.

[0062] The self-reset switch has a fault protection function. When an abnormal state occurs in the circuit, it can automatically disconnect the circuit to protect the equipment and system from damage. The combination of intelligent control switch and self-reset switch can avoid equipment failure or safety accidents caused by misoperation.

[0063] In some embodiments, see Figure 4 , in response to the intelligent control process, the steps of adjusting the load by starting the relay and closing the relay include: In response to the start relay being energized, the load is controlled to start working through the self-locking circuit; In response to the closing relay being energized, the self-locking circuit is de-energized and the load stops working.

[0064] Relays have precise switching characteristics that enable them to start or stop loads exactly when needed. This precise control helps ensure that loads start and stop working at the right time, thereby improving the operating efficiency of the entire system.

[0065] The relay switches quickly and stably, and can start and shut down the load in a short time. This fast response feature helps improve the stability of the entire system, especially in application scenarios where the load needs to be started and shut down frequently.

[0066] By precisely controlling the operating time of the load. Relays usually have standardized interfaces and connection methods, making them easy to integrate with other circuit components or systems. Since the relay structure is simple and easy to check, system maintenance becomes easier and faster. In the event of a fault, the damaged relay can be quickly located and replaced to restore normal operation of the system.

[0067] In some embodiments, see Figure 4 , in response to the manual control process, the steps of adjusting the load by the start relay normally open contact and the close relay normally closed contact in the start relay and the close relay include: In response to the start relay being energized and the circuit being self-locked, the normally open contact of the start relay is closed, and the load starts working; In response to the closing relay being energized, the normally closed contact of the closing relay is disconnected, the self-locking circuit loses power, and the load stops working.

[0068] Using normally open and normally closed contacts, interlocking and self-locking circuits can be designed to prevent abnormal startup or shutdown of loads due to misoperation. By combining different types of relays and contacts (such as delay relays, counting relays, etc.), multiple control modes can be achieved to meet different control needs.
