[0023] A mine flameproof and intrinsically safe vehicle domain controller, such as Figure 1 As shown, the upper end surface of the flameproof box body 1 is provided with a flameproof box upper cover plate 14 of an integrated structure;

[0024] like Figure 2As shown, the flameproof box 1 has a built-in central operation control module, which integrates the whole vehicle control function module, the whole vehicle low-voltage digital power distribution function module, the remote monitoring function module and the electrical isolation function module, and is used for whole vehicle control, precise power supply management, networked mine digital management center and remote program upgrade. The central operation control module can be functionally split into multiple functional modules, that is, split into multiple circuit boards, which are arranged in the control cavity and wiring cavity of the flameproof box, and the multiple circuit boards are arranged in layers up and down, which can effectively reduce the layout size of the internal space of the cavity, and achieve the miniaturization and lightweight design of the flameproof box structure. The central operation control module is installed in the flameproof box by an insulating mounting column, and mechanical isolation is formed between the flameproof box; the central operation control module realizes the signal conversion, transmission and isolation between the intrinsically safe and non-intrinsically safe circuits through electrical isolation, and ensures that the electrical characteristics of the associated equipment do not affect each other.

[0025] The following specific embodiment proposes a functional split design scheme that complies with the national standards for flameproof and intrinsically safe electrical equipment and takes into account the miniaturization and lightweight design of the flameproof box structure. Specifically, it is split into four functional modules: vehicle control function module 2, vehicle low-voltage digital power distribution function module 3, remote monitoring function module 4 and electrical isolation function module 5. The modules are arranged in the control chamber 11 and the wiring chamber 12 of the flameproof box 1 and arranged in upper and lower layers. The flameproof box 1 is divided into a control chamber 11 and a wiring chamber 12 by a partition 7. The vehicle low-voltage digital power distribution function module 3 is located in the control chamber 11, and the vehicle control function module 2, the remote monitoring function module 4 and the electrical isolation function module 5 are located in the wiring chamber 12. The partition 7 is provided with a through hole, and a flameproof terminal 16 is installed in the through hole to realize the flameproof electrical connection between the functional modules in the control chamber 11 and the wiring chamber 12.

[0026] A plurality of flameproof cable lead-in devices 15 are fixedly provided on the right end surface of the wiring chamber 12 for externally connecting explosion-proof and intrinsically safe cables.

[0027] The flameproof box 1 adopts a split chamber design, which is divided into two chambers: a control chamber 11 and a wiring chamber 12;

[0028] The flameproof flange surfaces of the control chamber 11 and the wiring chamber 12 of the flameproof housing 1 are designed in an integrated manner, thereby simplifying the product structure and cost.

[0029] The upper cover of the control chamber 11 and the wiring chamber 12 is integrated, that is, the flameproof box upper cover 14, which reduces the number of product parts and costs. The flameproof flange surface of the flameproof box 1 and the flameproof box upper cover 14 form a first flameproof joint surface.

[0030] The flameproof box upper cover 14 is provided with an annular groove and an O-ring to ensure the airtightness of the first flameproof joint surface;

[0031] Among them, there is a partition 7 between the control chamber 11 and the wiring chamber 12 of the flameproof box 1, and a through hole is set on the partition 7. The flameproof electrical connection between the control chamber 11 and the wiring chamber 12 is completed by installing the flameproof terminal 16. The inner surface of the through hole of the partition 7 and the cylindrical installation surface of the flameproof terminal 16 constitute a second flameproof joint surface.

[0032] The internal structure of the explosion-proof box 1 uses mechanical isolation to isolate the built-in central operation control module from the ground.

On the basis of convenient installation and maintenance, the space utilization rate of the structural layout of the control cavity 11 is effectively improved, so as to achieve the purpose of reducing the volume, weight and cost by side installation, and form mechanical isolation with the flameproof box 1 that meets a certain creepage distance and electrical clearance.

[0035] Among them, the three functional modules, namely the vehicle control functional module, the remote monitoring functional module 4, and the electrical isolation functional module 5, are fixedly installed in the wiring cavity using rubber insulating columns and arranged in upper and lower layers to reduce the internal space layout size of the cavity and achieve the purpose of miniaturization and lightweight design of the flameproof box structure, and form mechanical isolation that meets certain creepage distances and electrical clearances between the flameproof box 1 and other electrical components.

[0036] Specifically, the vehicle control function module 2 is fixedly mounted on the bottom plate of the wiring cavity 12 using rubber insulating columns 6, and forms mechanical isolation with the flameproof box 1 and other electrical components that meets certain creepage distances and electrical clearances.

[0038] Specifically, the electrical isolation function module 5 is fixedly installed above the vehicle control module 2 using a rubber insulating column 6, and forms mechanical isolation between the flameproof box 1 and other electrical components to meet certain creepage distances and electrical clearances.

[0039] The explosion-proof box 1 adopts a flameproof and intrinsically safe design, and the associated equipment connected thereto includes both intrinsically safe electrical equipment and flameproof electrical equipment.

[0040] Among them, the intrinsically safe electrical equipment connected to each functional module in the explosion-proof box 1 must be electrically isolated by the electrical isolation module 5 to achieve signal conversion, transmission and isolation between intrinsically safe and non-intrinsically safe circuits, ensuring that the electrical characteristics of the associated equipment do not affect each other.

[0041] The vehicle low-voltage digital power distribution function module 3 is a non-intrinsically safe high-power function module and must be installed in the control cavity 11 of the flameproof box 1. The flameproof electrical connection between the control cavity 11 and the wiring cavity 12 is completed through the flameproof wiring terminal 16 wiring harness.

[0042] Among them, one end of the flameproof terminal 16 harness is located in the control cavity 11, and is connected to the vehicle low-voltage digital power distribution function module 3 through a connector, and the other end is located in the wiring cavity 12, connected to the terminal block circuit board and the vehicle control function module 2, the remote monitoring function module 4 and the electrical isolation function module.

[0043] Among them, the flameproof associated equipment uses flameproof cables, which are indirectly introduced into the wiring cavity 12 of the flameproof box 1 through the flameproof cable introduction device 15, and are connected to the vehicle low-voltage digital power distribution function module 3 through the terminal block circuit board.

The signal conversion, transmission and isolation between the intrinsically safe and non-intrinsically safe circuits are completed through the electrical isolation function module 5 to ensure that the electrical characteristics of the associated equipment do not affect each other.

[0045] As described above, the vehicle control function module 2 is a non-intrinsically safe low-power electrical component, which can be installed in the control cavity or in the wiring cavity. In this example, in order to reduce the number and cost of the flameproof terminal blocks 16 on the partition 7 between the cavities, it is chosen to be installed in the wiring cavity 12 of the flameproof box 1.

[0046] The flameproof associated equipment is directly introduced into the wiring cavity 12 of the flameproof box 1 through the flameproof cable and the flameproof cable introduction device 15, and is connected with the vehicle control function module 2 through the terminal block circuit board.

[0047] Among them, the intrinsically safe associated equipment is directly introduced into the wiring cavity 12 of the flameproof box 1 through the intrinsically safe cable and the flameproof cable introduction device 15, and is connected with the vehicle control function module 2 through the electrical isolation function module 5. The signal conversion, transmission and isolation between the intrinsically safe and non-intrinsically safe circuits are completed through the electrical isolation function module 5 to ensure that the electrical characteristics of the associated equipment do not affect each other.

[0048] Among them, the vehicle control function module 2 is connected with the vehicle low-voltage digital power distribution function module 3, the remote monitoring function module 4 and the electrical isolation function module 5 through the internal wiring harness connector.

[0049] The remote monitoring function module 4 is an intrinsically safe low-power electrical component and can be installed in a control cavity or a wiring cavity. In this example, in order to reduce the number and cost of flameproof terminals 16 on the partition 7 between cavities, it is chosen to be installed in the wiring cavity 12 of the flameproof box 1.

[0050] Among them, intrinsically safe GPS antennas, 4G antennas or 5G antennas and other intrinsically safe associated equipment are directly introduced into the wiring cavity 12 of the flameproof box 1 through intrinsically safe cables and flameproof cable introduction devices, and are connected to the remote monitoring function module 4;

[0051] Among them, the remote monitoring function module 4 is connected with the vehicle control function module 2 and the vehicle low-voltage digital power distribution function module 3 through the electrical isolation function module 5 in the wiring cavity 12.

[0052] The central operation and control module adopts the CAN bus communication network and the 485 communication network to perform interactive control between the vehicle's electrical equipment, and uses WIFI, 4G or 5G wireless transmission methods to complete the vehicle's remote data upload and remote program upgrade of the vehicle control software, effectively improving the vehicle's intelligent networking, and helping customers to grasp the operating status of the vehicle's electrical equipment in a timely and accurate manner, reducing customer usage and maintenance costs.
