Accompanying drawing explanation
After reading the following description of non-limiting example of the present utility model and checking accompanying drawing, will understand better the utility model, wherein:
-Fig. 1 shows the schematic diagram of the control system forming according to the utility model.
The specific embodiment
Fig. 1 shows braking control system 1.
This system 1 comprises electronic circuit board, an electronic circuit board preferably, and it is with the assembly that is designed to realize required function of some.
Electronic circuit can comprise the relay of microcontroller 20 and interface and suitable power.
Electronic circuit comprises terminal, the different elements that it is electrically connected to described circuit to be controlled by system or control the different elements of drg operation.
Power supply 2 corresponding to for example 230V50Hz single phase poaer supply of electric power network or inverter is connected to circuit.
Drg 4 and 5 is connected respectively to the terminal of circuit to " Brake1 (drg 1) " and " Brake2 (drg 2) ".
When system is opened drg 4 or 5, the order of opening drg preferably provides according to order below:
The 207V of 1s (calling voltage), the voltage for example obtaining by full-bridge rectification,
All the other time 103.5V (maintaining voltage), the voltage for example obtaining by half wave rectification.
Drg 4 and 5 is spring-loaded, that is to say, under motorless state, it stops the rotation of motor reel.
In normal mode, two drgs 4 and 5 are powered simultaneously, and the energy that power supply station needs is taken from power supply 2.By logic, input 10, by system 1, receive the order of opening drg.This input 10 is connected to the changer to electrical motor power supply, or is connected to the controller of controlling elevator operation.
In Actuator Test Modes, in order to test independently continuously drg 4 and 5, to a drg permanent supply, and another normally moves.
In normal mode or Actuator Test Modes, across the motor control end 25 to 27 of electronic circuit, there is the output voltage of changer.
By means of two that are connected respectively to button for example or other switches corresponding logics input T 1and T 2, select the drg being held open.
Remain on normal operating drg and controlled by logic input 10, energy is taken from power supply 2.
Electronic circuit is designed such that if input T 1and T 2close simultaneously, drg is not powered so.
By means of logic input 12, make the switching of emergency mode come into force (also referred to as " enabling "), logic input 12 is for example connected to key operation switch or urgent chain.If input 12 indications are switched to emergency mode, control inputs 10 (also referred to as " unlatching ") and test input T 1and T 2then suppressed, two drgs 4 and 5 are controlled simultaneously, and the energy of drg power supply is taken to power supply 2.
In emergency mode, drg is controlled by logic input 14, and logic input 14 is connected to button or controls the controller of elevator operation.
If due to the state that input 14 places force, drg is opened, synchronous motor M is likely driven by the load of lift car so.The voltage causing by means of the Terminal of motor place that is connected to the input 25 to 27 of electronic circuit, the speed of measurement electrical motor.If the voltage mutually reaches threshold voltage, 280V peak value for example, the electric current that system 1 is cut off in drg 4 and 5, thus electrical motor is stopped operating.
The frequency transformer (not shown) of controlling electrical motor M enters its output at emergency mode run duration and no longer supplies the pattern of any voltage to electrical motor.Therefore the voltage that is independent of changer causing at motor terminal place during electrical motor rotates is sine-shaped.
If control electrical motor in normal operation mode or Actuator Test Modes, the output voltage of changer appears at end 25 to 27 places so.
Even if electrical motor has fault also must implement reliably emergency mode.In case of emergency, do not exist the reply across end 25 to 27 voltage not mean that lift car is not mobile, because may have the cable for example disconnecting or the electrical motor burning.System 1 detects does not have voltage, and drg On/Off several times in succession in this case, and for example, drg 4 and 5 is opened 5s and closes 5s, until provisional order stops, or until at corresponding input 16 places, provides the order of arrival floor.
By terminal Brake1 and terminal Brake2, drg 4 and 5 is powered respectively.In order to meet the requirement of standard EN 81-1 and A3 § 12.4.2.3.1, electronic circuit have two independently cutter for being cut to the power supply of each drg: the cutter that is called as " service cutter " for example being formed by rectification electronics package as transistor, thyristor or bidirectional triode thyristor by one or more semiconductor subassemblies, and copy the cutter that is called as " emergency cut-off device " that electromagnetic relay (state-copy electromagnetic) forms by state.Service cutter is controlled by control inputs 10, and emergency cut-off device is by inputting 12 controls.Coupling or the non-matching state of logic output CS copy services cutter, logic output CU copies coupling or the non-matching state of emergency cut-off device.This allows the controller of control elevator operation to know the state of cutter, as the situation of traditional electromechanic contactor.
In order to cancel the emergency cut-off device of opening when there is no electric power network, system 1 is exported, directly in emergency mode, drg 4 and 5 is powered via Brake1 and Brake2 by hard closing emergency cut-off device.
While there is Fisrt fault on the circuit that emergency mode must be able to be used in normal mode, move.Emergency mode while being used for the redundancy of the circuit of drg power supply therefore can be used for guaranteeing to occur Fisrt fault.
Diode/resistor/rheostat assembly is included into each output Brake1 and Brake2 to eliminate the magnetic energy of drg in the situation that of supply disconnecton.In the situation that the cut-out in normal operation mode is only eliminated energy in the resistor of drg.
Electronic circuit comprises relay 30, and it is by 35 power supplies of microprocessor/microcontroller Automatic Control Unit, and the object of relay 30 is the conformability that check the different input and output states of electronic circuit.Under abnormal condition, stop, to electromagnetic relay 30 power supplies, exporting accordingly 40 change states, this makes it possible to for example stop the operation of lift facility and/or signals malfunction.
The connection inputing or outputing to logic is advantageously reorganized in the detachable touch block with safety device (foolproof device).
For example by 230V source of AC network to the power supply of circuit supply connect, to the connection of electrical motor and also advantageously reorganized on the fool proof detachable touch block of tool to the connection of drg.
The utility model is not limited to presented example.
For example, can use analogous circuit rather than the different function of digital circuit.
Logic input 16 is optional.
In a kind of modification, electronic circuit does not receive the voltage at Terminal of motor place.In this case, electrical motor can be furnished with coil pickup, and it is by as provided information about axle velocity of rotation to electronic circuit with the circuit 60 as shown in dot pattern in Fig. 1.This coil pickup for example provides the square-wave signal that often turned for 16 cycles.
In another modification, electronic circuit receives the voltage at motor terminal place and the information that coil pickup transmits by circuit 60.
