Detailed ways

FIG. 1 is a diagram showing Embodiment 1 of the present invention.

The elevator system of the present embodiment includes: a group supervisory control device 1, car control devices 2A to 2C, which are subordinate control devices of the group supervisory control device, and car control devices 2A to 2C of the first to third cars controlled by the car control devices. 3C.

The car control devices 2A to 2C transmit the information of the car control devices 3A to 3C to the group supervisory control device 1, and the group supervisory control device 1 controls the car control devices 2A to 2C based on the transmitted information.

On the side of the hoistway of each machine, there are commercial power sources 41-44, chargers 51-54 that convert the power of the commercial power sources into DC or AC, and control circuits 61-64 that control the chargers 51-54. , a charging device composed of power supply elements 71-74 and position sensors 81-84.

The position sensors 81-84 detect whether the moving body (the counterweight 11 or the car 12) is at a predetermined position, that is, a charging position, and output a charging start signal to the control circuits 61-64 when the moving body is at the predetermined position. The control circuits 61 to 64 receive the signal, and control the chargers 51 to 54 to supply electric power to the moving body side through the power supply elements 71 to 74 .

When the position sensors 81-84 detect that the moving body deviates from a predetermined position, the control circuits 61-64 stop the chargers 51-54.

The charging device installed on the lifting path on the counterweight side is arranged on the reference floor and the lowermost floor, and the charging device installed on the elevator path on the car side is arranged on the uppermost floor and the reference floor.

On the waiting hall side of each floor, a waiting hall call button 9 and a display device 10 are provided. The state of the battery 111 of the counterweight 11 or the battery 121 of the car 12 is displayed on the display device 10 .

A counterweight 11 and a car 12 are suspended from the respective number machines 3A to 3C via pulleys 13 .

A battery 111, an inverter 112 (inverter) connected to the battery 111, an electric motor 113 connected to the AC side of the inverter 112 and driven by the inverter 112, a power receiving element 114, and a detector are mounted on the counterweight 11. A battery state detecting device 115 and a signal sending and receiving device 116 for the remaining power of the battery 111 . Further, the pulley 117 is connected to the motor 113, and the pulley 117 is rotated by driving the motor to drive the counterweight 11 up and down. The inverter 112 is controlled by a control signal output from the car control device 2A. The control signal is wirelessly received by the signal transmitting and receiving device 116 and output to the converter 112 .

The power supply elements 71 and 72 and the power receiving element 114 of the charging device are made of a metal with a high permittivity, and are in direct contact with each other, so that the electric power supplied from the charging device is supplied to the battery 111 via the power receiving element 114 . Here, when the electric power supplied from the charging device is AC, it is necessary to install a rectifier between the power receiving element 114 and the battery 111 .

The value detected by the battery state detecting device 115 is transmitted to the car control device 2A through the signal transmitting and receiving device 116 . In the car control device 2A, it is determined whether the remaining power of the battery 111 is equal to or less than a predetermined reference value, and when the remaining power is equal to or less than the reference value, an operation command to automatically start the charging operation mode is output. Here, the so-called charging operation mode means that when the counterweight 11 stops at the charging device installation floor, a "call" is generated on the floor where the car 12 stops.

The "call" can be any one of a car call and a hall call.

The above-mentioned reference value is set to be larger than the amount that can travel to the charging device installation floor. By doing so, the counterweight 11 can move to the charging device installation floor before the battery 111 is exhausted.

In addition, the above-mentioned reference value may be set to be larger than the amount by which the counter weight 11 can reciprocate once between the uppermost stage and the lowermost stage and can travel to the charging device. In this case, even when a passenger is on board and the remaining battery power is lower than the reference value, it is possible to travel to the floor requested by the passenger, and to travel to the charging device installation floor before the battery 111 is exhausted.

In addition, the remaining power of the battery 111 can be detected by measuring the voltage of the battery 111 or the current flowing into and out of the battery.

The car 12 is loaded with a battery 121, an inverter 122 connected to the battery 121, an air conditioner 1231 connected to the inverter 122, a lighting 1232, an operation panel 1233, a power receiving element 124, and a detection battery 121. The battery state detecting device 125 and the signal sending and receiving device 126 of the remaining power.

The inverter 122 is controlled by a control signal output from the car control device 2A. The control signal is wirelessly received by the signal transmitting and receiving device 126 and output to the converter 122 .

The power feeding elements 73 and 74 and the power receiving element 124 of the charging device are made of metal with a high permittivity, and are in direct contact with each other, so that the electric power supplied from the charging device is supplied to the battery 121 via the power receiving element 124 . Here, when the electric power supplied from the charging device is AC, it is necessary to install a rectifier between the power receiving element 124 and the battery 121 .

The value detected by the battery state detecting device 125 is transmitted to the car control device 2A through the signal transmitting and receiving device 126 . In the car control device 2A, it is determined whether the remaining power of the battery 121 is equal to or less than a predetermined reference value, and when the remaining power is equal to or less than the reference value, an operation command to automatically start the charging operation mode is output. Here, the charging operation mode refers to a "call" for a floor where a charging device for supplying electric power to the car 12 is installed.

The "call" can be any one of a car call and a hall call.

The setting of the above-mentioned reference value is the same as that of the above-mentioned counterweight.

In addition, the detection method of the remaining electric quantity of the battery 121 is also the same as the above-mentioned counterweight.

FIG. 2 is a diagram showing a detailed configuration of the car control device 2A shown in FIG. 1 .

The configuration shown in these figures will be described using the flow charts shown in FIGS. 3 and 4 .

The remaining battery power is detected by the battery state detectors 115 and 125 mounted on the counterweight 11 and the car 12 (step S1), and the information on the remaining battery power is sent to the car control device 2A. The transmitted remaining battery power information is input to the battery state display circuit 23 and the charge/display/exchange request generation unit 21 . The battery state display circuit 23 displays the detected remaining battery power on the display device 10 (steps S2, S3). In the charge/display/replacement request generation unit 21, the reference battery remaining power stored in the set value data storage unit 22 is compared with the detected battery remaining power, and if it is smaller than the reference battery remaining power, a display request and charging requirements. If it is greater than the reference remaining power, return to step S1 (steps S4, S5, S6). Above-mentioned display request is input in the battery status display circuit 23, and the battery status display circuit displays the meaning of "need charging" on the display device 10 (step S3)

When the above charging request is generated, a "call" to the charging layer is generated (step S11).

In addition, the so-called charging floor refers to the floor where the car stops when the counterweight stops on the floor where the charging device is installed in the case of the counterweight, and refers to the floor where the charging device is installed in the case of the car.

Here, the charge/display/replacement request generation unit 21 counts the number of times the charge request has occurred (step S7). When the number of charge requests exceeds the reference charge count stored in the reference value data, a request to replace the batteries 111, 121 is generated (steps S8, S9). This replacement request is sent to the maintenance company (step S10).

The "call" generated in step S11 is input to the speed command generator 24, and the speed command generator 24 outputs a command to run at a low speed to the charging layer to the inverter 112 mounted on the counterweight 11 (step S12). Inverter 112 accepts the instruction, and drives motor 113 to run the elevator to the power supply floor at a low speed.

After reaching the charging floor, power is supplied from the supply device to the counterweight 11 or the car 12 side (step S14). The charge amount is calculated by the charge amount calculation circuit 27 based on the data output from the control circuits 61 to 64 (step S15). The calculated charging quantity is input to the distributed standby OR reference level return command generation unit 26, and after the command generation unit 26 judges that the charging is completed, the distributed standby or reference level return command is output to the speed command generation unit 24 (step S16 ). The speed command generating unit 24 sends a command to the inverter 112 according to the command, so that the elevators are on standby or return to the reference floor.

Next, Fig. 4 is used to illustrate the process of the passenger pressing the call button in the waiting room.

When the guest presses the call button in the waiting hall (step S18), it is judged by the operation judging circuit 25 whether it is charging (step S19). Also, the operation judging circuit 25 inputs the charging amount from the above-mentioned charging amount calculation circuits 61 to 64 . If not charging, then the operation judgment circuit 25 produces a "call" to the request floor (step S21), and the speed instruction generation part 24 sends an instruction to the above-mentioned converter 112 according to the "call", so that the elevator is moved to the request floor (step S22 ).

If it is determined in step S19 that the battery is being charged, the operation determination circuit 25 determines whether it is possible to operate based on the charging information obtained by the charge calculation circuit 27 and the information on the "call" occurrence level. If the result is OK, a "call" is made to the requesting layer (step S21), and the process proceeds to the above-mentioned step 22.

If the operation is not possible, an instruction is issued to the battery state display circuit 23 to display the content "charging" on the display device 10 (step S23).

Next, the group supervisory control device 1 will be described.

FIG. 5 is a block diagram of the group supervisory control device 1 .

The group management control device 1 has a waiting hall call collection unit 152 that collects information from the waiting hall call button, and a battery information collection unit 151 that collects battery information through each number machine, and collects car calls, car calls, and car calls through each number machine. Car information collection unit for car information such as location.

Furthermore, in the allocating unit 154, a car to be served is selected based on the information collected by the battery information collecting unit 151, the waiting hall call collecting unit, and the car information collecting unit. For example, the car of the car with a smaller remaining battery power is controlled so that the elevator of the car with a larger battery remaining power is allocated preferentially.

Furthermore, the group supervisory control device 1 in this embodiment includes a charging pattern prediction unit 55 , a first reference value storage unit 56 , a second reference value storage unit 57 , a charging/display request generation unit 58 , and a display circuit 59 .

The first reference value stored in the first reference value storage unit is the same data as the reference value stored in the set value storage unit 22 shown in FIG. Need to recharge. The second reference value stored in the second reference value storage unit 57 is a value larger than the above-mentioned first reference value.

In the charging mode prediction unit, the information on the remaining battery power input from the remaining battery power collecting unit 151 is compared with the first reference value stored in the first reference value storage unit 56 and the second reference value storage unit 57. The second reference value of , to judge whether it is about to enter the charging mode.

The result of this judgment is input to the charging/display request generation unit 58 . When it is predicted that multiple number machines will enter the charging mode, the charging/display request generation unit 58 generates a "call" for the charging layer, and sends a call to one of the number number machines that will enter the charging mode. The control unit sends this signal.

Also, according to a signal from the charging/display circuit 59, it is displayed that the charging mode will be entered. Or display the situation of entering the charging mode.

Next, the processing flow of the group supervisory control device 1 will be described using FIG. 6 .

Battery information, waiting hall call information, and car information are collected by the remaining battery power collection unit 151, the waiting hall call collection unit 152, and the car information collection unit 153 (step S61). Then judge whether there is "waiting hall call", if there is no "waiting hall call", then transfer to step 61, if there is "waiting hall call", then transfer to step S63. In the allocating unit 154, based on the information collected in step S61, the most suitable number machine for serving the "calling in the waiting room" is selected (step S63).

In step S64, it is determined whether or not the remaining battery power is equal to or less than the first reference value in any number car. That is, it is judged whether it is necessary to start the charging operation.

If it is judged that the remaining battery power of any number machine is below the first reference value, the number machine starts charging operation. This charging operation is performed by the charging/display request generator 58 of the group supervisory control device 1 generating a "call", and sending the "call" signal to the speed command generator of the car control device (step 67).

Then, if it is judged that the remaining battery power is not lower than the first reference value in any number car, the process proceeds to step 65 .

In step 65, it is determined whether or not the remaining power of the batteries of the plurality of car models is greater than or equal to the first reference value and less than or equal to the second reference value. That is, it is judged whether there is a possibility that multiple number machines start charging at the same time (step 65).

When the remaining battery power of the plural number machines is greater than or equal to the first reference value and less than the second reference value, any one of the number machines is started to charge in order not to simultaneously charge the plurality of number machines. As described above, the charging operation is performed by causing the charging/display request generating part 58 of the group supervisory control device 1 to generate a "call", and sending the "call" signal to the speed command generating part of the car control device (step 66).

When the remaining battery power of a plurality of mobile phones is not more than the first reference value and not more than the second reference value, the process proceeds to step 61 .

The display in this embodiment will be described below.

FIG. 7 is a diagram showing a display example of the display device 10 in this embodiment.

Fig. 7(a) is a detailed view of the layer portion shown in Fig. 1 . It has an elevator door 172, a display device 171 arranged on the upper part of the elevator door 172 and indicating the running direction of the synchronous floor, and a display device 10 indicating the state of the battery.

Battery information is displayed on the display device 10 . The battery information is input to the car control device from the signal transmitting and receiving devices 116 and 126 shown in FIG.

Furthermore, when the battery is being charged, as shown in FIG. 7( b ), displays indicating that the charging operation is in progress, such as "adjusting", "charging", and "preparing", are displayed on the display device 10.

And, when it is judged by the charging/displaying/replacing request generation unit 21 shown in FIG. 2 that it is necessary to replace the battery (step S9 shown in FIG. 3 ), the battery state display circuit 23, as shown in FIG. 7( c), On the display device 10, displays prompting battery replacement such as "battery replacement required" and "battery replacement please" are displayed.

And when it is judged by the group supervisory control device 1 that the remaining power of the batteries of the multiple number machines is above the first reference value and below the second reference value, the display circuit 59 controls the display device 10, as shown in FIG. 7( d ). Displays such as "charging soon" and "starting charging immediately" are displayed to indicate that the charging operation is about to start.

Furthermore, in the group supervisory control device, when it is judged that the remaining power of the battery is equal to or less than the first reference value, the display device 10 performs a display as shown in FIG. 7( b ).

In addition, the displays shown in FIGS. 7( a ) to ( d ) may be performed on the display device 171 .

By performing the display as described above, it is possible to eliminate anxiety and dissatisfaction of the user, and it can also be used for maintenance such as displaying battery replacement information. The same effect as above can also be obtained by integrating the battery state display device with the display device indicating the synchronous floor or the running direction, or with the hall call button device.

Using this display, the user can understand that the battery is being charged and relieve anxiety.

And, when charging, by clearing the display of the display device 171 or the display device 10 showing the synchronous floor or the running direction, it can be understood that the elevator cannot be used because it is charging. In addition, the display shown in FIG. 7 may respond only when the user presses the hall call button, and in this case, the power consumption may be small. In addition, it may be displayed on a display device in the car room in consideration of an emergency, or not only a display but also a transmission device by sound may be used.

According to the first embodiment of the present invention, it is characterized in that a "call" of the power supply layer occurs when the remaining battery power is below a reference value.

Here, the "call" in an elevator refers to an operation reservation generally issued by a person using an elevator to indicate the floor the user is on, and at the same time indicate the direction of travel after boarding or the floor where the user wants to stop. That is to say, during the operation of "calling" to other layers, even if a "call" to a specified layer occurs, it does not immediately run to the specified layer, but after completing the operation to other layers, it proceeds to the specified layer operation.

In this embodiment, since the "call" caused by the remaining power of the battery is different from the call issued by the user, it is possible to move the elevator to the power supply floor without causing obstacles to the user, compared with forcing the elevator to move to the power supply floor. The power layer moves.

Moreover, in this embodiment, since the battery is used as the power supply in the car and the power supply to the counterweight, and the power is supplied to the battery at a predetermined floor, it is possible to eliminate the need for a tail rope for a power supply, and it is possible to achieve weight reduction and controllability. Undesirable effects caused by the swing of the tail rope. And, on the lifting path of the glass structure, it makes the appearance beautiful.

In addition, according to the present embodiment, since the position sensor is provided and electric power is supplied using the sensor, electric power can be reliably supplied.

In addition, according to this embodiment, since the charging device is arranged on the base layer, the power supply opportunities can be increased, the battery is not easily consumed, and since the large charge and discharge of the battery can be controlled, the decrease in battery life can be controlled.

In addition, in this embodiment, the charging device for supplying power to the counterweight side is arranged on the lower floor, and the charging device for supplying power to the car side is installed on the upper floor. Preferably, the charging device for supplying power to the counterweight side is arranged on the lowermost floor, and the charging device for supplying power to the car side is arranged on the uppermost floor.

This is because, generally, when there are few passengers or passengers, the car moves to the upper floor and the counterweight moves to the lower floor, which can be moved with a small driving force. In addition, there are more opportunities to operate with fewer passengers than to operate at full capacity.

That is, by arranging the charging device as in the present embodiment, it is possible to reduce the power consumption during the charging operation and reduce the possibility of the battery being exhausted.

In addition, in this embodiment, since "battery remaining power" is displayed on the display device, the manager of the building can check the battery status of each number machine. In addition, since "charging" is displayed on the display device, even if the elevator does not start, it is possible to relieve the user's anxiety about whether the elevator is malfunctioning.

In addition, according to the present embodiment, when a plurality of elevators are about to enter the charging operation, one elevator is charged in advance, so it is possible to avoid the simultaneous charging operation of multiple elevators, and it is possible to prevent a significant drop in transportation efficiency due to simultaneous charging. reduce.

Embodiment 2 of the present invention will be described below.

Fig. 8 is a diagram showing Embodiment 2 of the present invention.

Although in Embodiment 1, the remaining battery power of the counterweight 11 and the batteries 111 and 121 of the car 12 are directly detected, in Embodiment 2 the state of the battery is estimated from the operating data.

It is a configuration in which a log storage unit 81 and a battery state calculation unit 82 are added to the first embodiment described above. The operation log storage unit 81 obtains and stores the data of the number of operations and the operation distance from the speed command generation unit 24 . In addition, information on the load weight is input from the car 12 and stored.

In the battery state computing unit 82 , the remaining battery power is estimated from the number of times of operation, the distance of operation, and the loaded weight. For example,

Calculate the remaining battery power by K1×(running times)+K2×(running distance)+K3×(loading weight) (K1, K2, K3: weighting coefficients).

When the estimated remaining battery power is equal to or less than a predetermined reference value, the processing after the charging operation and the like is performed in the same manner as in the first embodiment described above.

According to the present embodiment, since the remaining battery power is estimated from the operating data, suitable charging operation can be performed even if a battery whose battery voltage varies little, such as a nickel metal hydride battery.

Moreover, when detecting the remaining power of the battery and transmitting the detected value to the car control device wirelessly, the wireless distance from the car control device will sometimes become longer as the counterweight or the car moves. , sometimes shortened. Therefore, since the wireless distance becomes longer, the car control device may not be able to grasp the remaining power of the battery, and may not be able to perform charging operation.

In this embodiment, since the remaining power of the battery is estimated based on the operating data, the above-mentioned problem does not occur, and an appropriate charging operation can be performed.

Embodiment 3 of the present invention will be described below.

Fig. 9 is a diagram showing Embodiment 3 of the present invention.

In the first and second embodiments, the remaining battery power of the batteries 111, 121 of the counterweight 11 and the car 12 is detected or estimated, but in the third embodiment, the charging operation is started at a predetermined time.

It is the structure in which the operating characteristic curve database 91, the internal clock 92, and the charge command 93 are added to the above-mentioned embodiment 1.

This embodiment is suitable for the case where the daily operating characteristic curve is known in advance. For example, in an office building, the operating rate is high when commuting in the morning and evening, and when taking a break at noon, but the operating rate at night is extremely low. And the operating rate on Sunday is also extremely low compared to other times. Also, the operating rate in summer is higher than in other seasons.

Such features are stored as a database in the operating characteristic curve database 91 . In other words, the operating characteristic curves for starting the charging operation in the morning and evening before the commuting time, the time before the lunch break, and the nighttime charging operation are stored in the operating characteristic curve database 91 .

Moreover, during the day when the operating rate of the elevator is high, the fast charging mode is adopted to prevent the battery from being exhausted and to charge with a large charging current, and at night when the operating rate is low, the battery is charged at a lower rate to extend the battery life. The operating characteristic curve of the nighttime (low-speed) charging mode in which the current performs the charging operation is stored in the operating characteristic curve database 91 .

The charge/display/replacement request generation unit 21 generates a "call" similarly to the above-mentioned embodiment based on the operating characteristic curve in the operating characteristic curve database 91 and the time input from the internal clock 92 .

The charging capacity command unit 93 also determines the charging capacity, the magnitude of the current during charging, and the charging time based on the operating characteristic curve in the operating characteristic curve database 91 and the time input from the internal clock 92, and sends the determined items to the control circuit 61. The control circuit 61 controls charging according to the transmitted signal.

Next, the processing flow of Embodiment 3 of the present invention will be described using FIG. 10 .

FIG. 10 is a processing flowchart of Embodiment 3.

In addition, steps S3, S5 to S17 are the same as those in the first embodiment described above.

In step 101, it is judged whether it is the set time. That is, it is judged whether it is time to start charging operation. As described above, the charge/display/replacement request generation unit 21 makes a determination based on the operating characteristic curve of the operating characteristic curve database 91 and the time input from the internal clock 92 .

If it is not the set time, it will transfer to step 101 again.

If it is set time, it will transfer to step S5, S6, S102.

The processing flow after steps S5 and S6 is the same as that of the first embodiment (the flow shown in FIG. 3 ), so it is omitted.

In step S102, the charging form is commanded. That is, the charge level command unit 93 determines the charge level, current magnitude during charging, and charging time based on the operating characteristic curve in the operating characteristic curve database 91 and the time input from the internal clock 92 , and sends the determined items to the control circuit 61 .

According to the present embodiment, since the charging current at the time of charging is reduced according to the use state of the elevator, the life of the battery can be extended.

Next, another embodiment of the counterweight side power supply unit shown in FIG. 1 will be described.

Fig. 11 is a diagram showing another example of a counterweight-side power supply unit.

In this embodiment, the power supply mode is a non-contact power supply mode.

AC power supply 41, charger 51, control circuit 61, position sensor 81, battery 111, converter 112, motor 113, battery state detection device 115, signal sending and receiving device 116 are the same as those shown in FIG.

In this embodiment, the power supply element 1101 for non-contact power supply and the power receiving element 1102 for non-contact power supply are used. constitute. Furthermore, a rectifier 1103 is connected between the battery 111 and the power receiving element 1102 for non-contact power feeding. In addition, a capacitor may be connected between the rectifier and the power receiving element for non-contact power feeding.

When power receiving element 1102 for non-contact power feeding and power feeding element 1101 for non-contact power supply face each other, electric power is supplied from charger 51 to battery 111 by electromagnetic induction.

By using the non-contact power feeding method in this way, it is possible to prevent corrosion due to rust of the power receiving element and the power feeding element, or deterioration due to friction, and there is an effect that no noise due to contact is generated.

Next, another embodiment of the car-side power supply unit shown in FIG. 1 will be described.

Fig. 12 is a diagram showing another example of a car power supply unit.

In this embodiment, the power supply mode is a non-contact power supply mode.

AC power supply 44, charger 54, control circuit 64, battery 121, converter 122, air conditioner 1231, lighting 1232, operating panel 1233 in the car, battery state detection device 125, and signal sending and receiving device 126 are the same as those shown in Fig. 1 .

In this embodiment, a power receiving element 1202 for non-contact power feeding and a power feeding element 1201 for non-contact power supply are provided. The power receiving element 1202 and the power feeding element 1201 are made of magnetic materials such as ferrite that can transmit energy at high frequencies. Furthermore, a rectifier 1203 is connected between the battery 121 and the power receiving element 1202 for non-contact power feeding. In addition, a capacitor may be connected between the rectifier and the power receiving element for non-contact power feeding.

When power receiving element 1202 for non-contact power feeding and power feeding element 1201 for non-contact power supply face each other, electric power is supplied from charger 54 to battery 121 by electromagnetic induction.

By using a non-contact power supply method, it is possible to prevent corrosion due to rust of the power receiving element and the power feeding element, or deterioration due to friction, and there is an effect that noise due to contact is not generated.

FIG. 13 is a diagram showing another example of a method of connecting a charger.

Fig. 13 is a view of each machine seen from above.

In Fig. 1, each power supply element of each number machine is respectively provided with a charger. Correspondingly, Fig. 13 is an example of charging a plurality of elevators with one charger.

The power supply element 7a for the No. 1 machine, the power supply element 7b for the No. 2 machine, and the power supply element 7c for the No. 3 machine are connected to one charger 5 . A battery 1303a is mounted on the moving body (car or counterweight) 1302a of the No. 1 machine, and the power receiving element 11a is connected to the battery 1303a.

In addition, similarly, a battery 1303b is mounted on the mobile body (car or counterweight) 1302b of the No. 2 machine, and the power receiving element 11b is connected to the battery 1303b. A battery 1303c is mounted on a moving body (car or counterweight) 1302c of the No. 3 machine, and a power receiving element 11c is connected to the battery 1303c.

In addition, changeover switches 1301a to 1301c are provided between the charger 5 and the power supply elements 7a to 7c, and a function of disconnecting the circuit of the power supply elements not being charged is added.

According to this embodiment, the number of chargers 5 can be reduced compared to the number of moving bodies, which has the effect of saving space and reducing costs.

In addition, by providing a switch to disconnect the circuit of the power supply element that is not being charged, it is possible to control the leakage of magnetic flux and improve the efficiency.
