Detailed description of the invention
In order to enable above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
See Fig. 1, this figure is one many cars construction elevator group control system structural representation that the embodiment of the present invention provides.
Master control system, for receiving floor call, response calling, scheduling car, the state of each car of analytical calculation simultaneously, and exporting control signal with this, controlling cage operation;
Multiple cage driving unit, is elevated independently for multiple car;
Be arranged at the running crane control device in car, for controlling described cage driving unit;
Multiple brake equipment, for braking described car;
Whether distance detection device, for monitoring range ability between multiple car, and control brake equipment with this and brake car; Distance detection device comprises the height detection coder that two apomecometers being separately positioned on car top and bottom and are arranged on cab interior or outside;
Multiple rotating mechanism, changes in upstream side and downlink side for controlling car;
Described master control system is controlled running crane control device, distance detection device, rotating mechanism by wireless or wired mode.
The control method of elevator with multiple compartments group control system comprises method of controlling security and a car response scheduling method, and wherein the control flow of method of controlling security as shown in Figure 2, comprises the following steps:
Step 101: the operation spacing of setting car
Minimum safe distance when user is run by master control system setting between car and between car and rotating mechanism, pressure stopping distance;
Step 102: calculate real-time spacing between each cage operation height and car
Each car height that master control system receiving range control monitor unit detects, and the distance between the upper and lower between each car and the distance between each car and operation front rotating mechanism are calculated in real time.The method of inspection of cage operation height and in real time spacing comprises two kinds of methods, method one: the difference using height detection coder detection car height then to be calculated between each car by master control system is inter-car distance; Method two: use car top and the apomecometer set by bottom detect the spacing between former and later two cars.If the bottom apomecometer of down running cars detects that distance that itself and the distance of below car or the top apomecometer of up car monitor itself and top car is less than minimum safe distance or is less than when forcing stopping distance in this step, then without the need to carrying out communication with master control system, distance detection device directly controls brake equipment and controls this down running cars or the deceleration of up car or stop.
Step 103: decision-making cage operation state
The inter-car distance calculated in step 102 and the distance between car and rotating mechanism are made comparisons with the minimum safe distance preset, pressure stopping distance by master control system, if inter-car distance is greater than minimum safe distance, then car normal speed is run; If spacing is less than minimum safe distance and is greater than pressure stopping distance, then car runs slowly; If spacing is less than force stopping distance, master control system controls brake equipment by running crane control device makes car force to stop.If the distance between car and rotating mechanism is less than minimum safe distance and is greater than pressure stopping distance, or when being less than pressure stopping distance, master control system monitors swivel when being in slew mode or non-initial position simultaneously, then control brake equipment by running crane control device and make car force to stop.
This step also comprises the adjustment for altitude to car; Height detection coder detects car height, and the rising or falling speed integration of master control system to car obtains the height difference in interval time simultaneously, contrasts, if there is deviation, correct with this value and the detection difference with time gap inner encoder.
As shown in Figure 3, C and the D car of upstream side allows up in concrete enforcement, A and the B car of downlink side allows descending.
In the up process of D car, master control system calculates the spacing of D car and C car according to the altimeter of D car and C car, when spacing is less than the minimum safe distance of setting, D car is down to low cruise, and when distance values is down to the pressure stopping distance of setting further, D car will stop, and No starting, after C car is up, spacing increases, and D car can restart.Equally, B car is in descending process, and when the distance values of distance A car is less than setting minimum safe distance, B car is down to low cruise, when distance values is down to the stopping distance of setting further, B car will stop, and No starting, after A car is descending, spacing increases, and B car can restart.
Meanwhile, be arranged on the spacing that apomecometer above D car detects top car, be less than when arranging, the parking of controls D car; Be arranged on the spacing that apomecometer below B car detects below car, be less than when arranging, the parking of controls B car.Therefore, if master control system lost efficacy, the apomecometer detection signal above and below each car still can rely on complete spacing too little time automatic train stop.
Car response scheduling method comprises step:
Step 201: master control system receives each floor call information with network communication mode;
Step 202: master control system analyzing and processing floor call information, distributes an item for every bar call information and carries out store management in a tabular form, forms call information list; Item in call information list comprises floor information and the upstream or downstream information of call information.
Step 203: master control system is according to set response mechanism, and appointment car completes the response to floor call automatically;
Step 204: master control system, after floor call is responded, deletes item corresponding in call information list, and in call information list, add the new call information item produced.

Rule four: downlink side response is not by the up call of responsive state;
When there is calling in upstream side, if the below of calling floor does not have car to respond, then the car of specifying downlink side to arrive recently is response car, and response car is by the rotating mechanism nearest apart from this car, rotate to upstream side from downlink side, up arrival calling floor;
Rule five: upstream side car response below is not by the up call responded;
Rule six: downlink side car response top is not by the downlink call responded;
Wherein regular five Sum fanction six for the treatment of in rule one to rule four not by the calling that responds or the calling being cancelled response by operating personal.
According to six rules of call, the calling of each floor by situation about responding as shown in Figure 4,
Rule one: the response of upstream side car is not by the upper party call responded

Rule four: downlink side response is not by the up call of responsive state
1st step: 4# car response C calling (A, B calling is responded in rule one, and therefore 4# car does not respond A, B calling);
2nd step: 3# car does not respond A, B, C calling (A, B and C calling is all responded by other car);
Except above four rules, also regular five Sum fanction six, for the treatment of in above four rules not by the calling that responds or the calling being cancelled response by operating personal.Such as, eliminate the response to C calling in 4# car, in 1# car, eliminate the response to D calling.
Rule five: upstream side car response below is not by the up call responded
1st step: 1# car response C calling
2nd step: 2# car does not respond C calling (C calling is responded by 1# car, if C calling continues to be cancelled response by 1# car, is then responded by 2# car);
Rule six: downlink side car response top is not by the downlink call responded
1st step: 4# car response D calling
2nd step: 3# car does not respond D calling (D calling is responded by 4# car, if D calling continues to be cancelled response by 4# car, is then responded by 3# car);
