Description
Technical field
The invention belongs to rescue investigation field of tool, be specifically related to a kind of essential safe type robot movement platform that is applicable to have under dangerous explosive atmosphere certain maneuverability.
Background technology
In disaster relief, the application scenario such as fire-fighting is explosive, environment of living in is flammable explosive gas abrim often, liquid or dust etc., the electrical equipment therefore used under these environment, explosion-proof security is the prerequisite an of necessity.According to GB GB 3846 " explosive atmosphere ", the explosion-proof type of current electric apparatus for explosive atmospheres has several.Wherein, the essential safe type " i " of GB GB 3846.4 defineds is a kind of type of explosion proof construc tion of electrical equipment, and it is by realizing explosion-proof by device interior and the issuable electro spark of connection wire or the calorific effect energy limited that are exposed to potential explosive border in the level that can not light.The heavy flameproof enclosure of needs not when the electrical equipment that meets the intrinsic safety type requirement is applied under explosive atmosphere, so volume is little, lightweight, be easy to carry and move, there are a lot of advantages.
The essential safe type protection class " ia " of take is example, when equipment requirement applies fault in worst situation, comprises short circuit and while opening circuit, the electro spark produced and calorific effect energy can not cause to be lighted.This is substantially that the electric power of maximum has everywhere applied restriction to system.At present, can meet the electrical equipment of essential safe type requirement, monomer whose power maximum can only be accomplished several watts to tens watts.Simultaneously, for the power supply of giving the power supply of essential safety equipment, also must meet identical security requirement, output power is received restriction.
On the other hand, under explosive atmosphere, search for, survey, the robot platform of the disaster relief, except needs have certain capacity weight.Also needing has stronger locomitivity, particularly, such as down-hole, under the application scenarios such as disaster scene, due to circumstance complication, requires robot platform to move on uneven ground.At present, have the robot product of stronger obstacle climbing ability and model machine a lot, but the maneuverability of these robot platforms all depends on heavy-duty motor, power can reach several hectowatts, does not obviously meet the requirement of intrinsically safe equipment.Some robots adopt multiple electric motors, the scheme of individual drive, although can reduce like this monomer power of motor, the requirement that distance meets essential safe type still has suitable distance, and reason is as follows:
1. motor monomer power is still bigger than normal, is at least tens watts;
2. power pack is still centralized or is halfway grouping stand alone type, and the power that single power supply is exported (comprises short circuit and open circuit) that requirement is above standard when applying the least favorable fault;
3. in order to control conveniently, the control signal of each electric motor units is by the intercommunication of bus driver unit.Simultaneously, unimpeded in order to guarantee signal, power supply exists altogether.When applying the least favorable fault, multiunit electric power is stack mutually likely.
Due to above-mentioned these reasons, current mobile robot platform can't be taken into account stronger locomitivity when meeting the code requirement of essential safe type.
Summary of the invention
For the max power constraint that solves intrinsic safety type equipment and the contradiction between robot motion's ability, the present invention proposes a kind of essential safe type robot movement platform, is meeting the effective lifting that realizes locomitivity under the prerequisite that essential safety requires.

Described power system comprises two or more motor modules, and mutual electrical isolation between each motor module, and each motor module comprises a motor, a power system supply module;
Wherein, each supply module in described power system only provides required power supply to the motor module at its place, the output of motor is connected with corresponding running gear, provide torque to corresponding running gear, by application force and the antagonistic force on running gear and ground, convert that robot platform advances or the power of obstacle detouring to;
Described whistle control system comprises signal path, control module, whistle control system supply module and signaling module, and described signaling module is connected on the control signal path through isolating device, and finally with control module, is connected by signal path;
Control module in whistle control system couples together by motor and power system in isolating device, signaling module, power system, and the control command that the control module in described signaling module reception whistle control system sends is controlled the operation of its corresponding motor.
The present invention can also change the quantity of motor module and position each other, carrys out the shape of power-handling capability and the robot of motivation of adjustment system.When motor module maximum power one timing adopted, the quantity of motor module is more, and the gross horsepower of system and power-handling capability are just stronger.The mechanical force that power system produces acts synergistically on running gear, by the effect on running gear and ground, converts that robot platform advances or the power of obstacle detouring to.
Meet the essential safety requirement in order to meet the robot platform complete machine, each electric and electronic assembly of system must meet the code requirement of essential safe type.Specifically, in each motor module, the output power of supply module is limited by current limiting device, applies worst fault outside supply module, and in short circuit or intermittent situation about opening circuit, its current-voltage characteristic meets the essential safe type requirement.Signaling module in each motor module is connected with control module by isolating device, thereby electric power can not produce stack, reaches the purpose of electrical isolation.Each motor module is installed, is reserved the modes such as fixing clearance, object partition by dispersion and realizes physical isolation.Realize that physical isolation and physically-isolated a plurality of motor module can regard a plurality of autonomous devices as.Under the prerequisite that meets the essential safety requirement, the gross horsepower of a plurality of autonomous devices is compared individual equipment and is increased exponentially.When the mechanical force that the power system formed when these motor modules produces acts synergistically on running gear, can be so that the locomitivity of complete machine significantly improves.In addition, in the whistle control system of robot platform, control module and corresponding supply module thereof meet the essential safety requirement, the monomer of each signaling module meets the essential safety requirement, owing to using isolating device to be connected between control module and a plurality of signaling module, so the electric current on a plurality of signaling modules can not introduced signal path or control module produces stack, therefore whole whistle control system meets the essential safety requirement.
Due to the application of foregoing invention scheme, bring following advantage:
1. the present invention adopts distributed power source and dynamic design, can effectively realize electric power is distributed to system everywhere, has avoided producing large electric current or high potential in part, has high security.Adopting isolating device between control module and between each motor module, thereby the electric power of each motor module can not superpose when fault occurs, and meets the requirement of essential safety.
2. due to physics and electric mutual isolation between each motor module in system, so can regard autonomous device as.The quantity of equipment is not subject to essential safety to require restriction.The mechanical force produced due to motor module again acts synergistically on running gear, common drive machines human body, thereby at each motor module, meet under the prerequisite of essential safety requirement, propulsive effort obtains and is multiplied, and has stronger motion and obstacle climbing ability.
