As shown in fig. 3, the overhaul control method includes:

s301, acquiring overhaul information received by an overhaul device after the overhaul device is accessed to a circuit of an elevator.

S302, a sending device based on maintenance information determines a first position where the maintenance device is located when the maintenance device is connected to a circuit of an elevator.

In an alternative embodiment, after the sending device based on the service information determines the first position where the service device is in when accessing the circuit of the elevator, the method further comprises: judging whether the shared module and the out-of-hall maintenance module are connected to the control cabinet or not based on the module connection information when the first position is out of the hall; if yes, executing a step of determining a second position of the elevator to be overhauled according to overhauling information; if not, determining that the overhaul device is not installed; and when the first position is the hoistway, judging whether the common module is connected to the electric box of the corresponding hoistway based on the module connection information, if so, executing the step of determining the second position of the elevator to be overhauled according to the overhauling information, and if not, determining that the overhauling device is not installed.

That is, when the maintenance device is used outside the hoistway, the common module and the outdoor maintenance module need to be all connected to the control cabinet, that is, the common module and the outdoor maintenance module need to be all connected to the circuits of the elevators, when the maintenance device is used in the hoistway, only the common module needs to be connected to the corresponding electrical box of the hoistway, that is, only the common module needs to be connected to the circuits of the elevators, and the outdoor maintenance module does not need to be connected to the circuits, so that the maintenance device is in an invalid state. Because the out-of-hall service module is inactive when the service device is used on a roof or pit, no access circuit is required. Specifically, the overhaul operation control module may provide point-to-point overhaul state information to the control cabinet, and thus, module connection information may be collected and provided by the overhaul operation control module.

By acquiring the access conditions of the shared module and the outdoor overhaul module, whether the overhaul device is installed or not can be accurately judged, manual confirmation is not needed, and the accuracy and the efficiency of elevator overhaul are improved.

S303, determining a second position of the elevator to be overhauled according to the overhauling information.

S304, judging whether the first position is consistent with the second position.

If not, S305 is executed, and if yes, S306 is executed.

S305, sending a setting error prompt signal to the overhauling device.

S301-S05 are similar to S101-S104 of the first embodiment, and specific reference is made to the relevant contents of S101-S104, which are not described herein.

S306, judging whether the first position is a hoistway.

If yes, S307 is executed, and if no, S310 is executed.

S307, acquiring switch connection information.

When the first position is a hoistway, that is, the current actual position of the overhaul device is a pit or a car roof, the overhaul device is connected with an electric box of the corresponding hoistway, and the switch connection information is acquired through the electric box connected with the overhaul device.

And S308, judging whether the emergency stop switch box corresponding to the well is connected to the control cabinet or not based on the switch connection information.

The pit and the car roof are respectively provided with a scram switch box, the scram switch boxes are respectively connected with corresponding electric boxes, and the scram switch boxes at the position of the car roof and the pit roof can be of the same or different types, and the invention is not limited to the above. Fig. 5 is a schematic view of a scram switch box, as shown in fig. 5. The emergency stop switch box is provided with an emergency stop switch C, an interface A and an interface B, wherein the emergency stop switch C is provided with at least two normally closed contacts. 1 contact is used for the elevator safety circuit, which is disconnected when it is disconnected, this contact being connected to the outside via interface a. And the other 1 contact is used for being connected in series with the main switch control loop and used for replacing the main switch control module of the overhaul device, when the contact is disconnected, a main circuit breaker arranged on the control cabinet is disconnected, and only when the contact is closed, the main circuit breaker can be connected, and the contact is connected with the outside through the interface B. When the emergency stop switch box is used on the top or the pit of the car, only the interface A is used for accessing the interface A of the top or the pit of the car, and the interface B is not used, so that the emergency stop switch effect of the safety loop is realized. When the emergency stop box is used outside a hall, the interface A and the interface B are respectively connected into the interface A and the interface B outside the hall, and the emergency stop switch box replaces a stop module and a main switch control module of the overhaul device.

When the first position is a hoistway, that is, the current actual position of the overhauling device is a pit or a car roof, as the overhauling device comprises the stopping module and the main switch control module, the two modules can ensure that the safety circuit and the main switch are in a normal state, when the overhauling device moves to the pit or the car roof, the stopping module and the main switch control module are also removed, and the safety module is connected into the safety circuit at the position outside the hoistway in series at the moment, so that the safety module replaces the functions of the stopping module and the main switch control module, and the safety circuit and the main switch are ensured to be in the normal state.

Therefore, in order to ensure that the safety circuit and the main switch can be in a normal state, it is necessary to determine whether the emergency stop switch box corresponding to the hoistway is connected to the control cabinet, if yes, S310 is executed; if not, S309 is performed.

Specifically, the following two cases are included:

the car roof is provided with a first emergency stop switch box, the first emergency stop switch box is connected with an electric box of the car roof, and when the first position is the car roof, first switch connection information is obtained; whether the first scram switch box is connected to the control cabinet is judged based on the first switch connection information. If yes, executing S310; if not, S309 is performed.

The pit is provided with a second emergency stop switch box, the second emergency stop switch box is connected with an electric appliance box of the pit, and when the first position is the pit, second switch connection information is obtained; judging whether the second scram switch box is connected to the control cabinet or not based on the second switch connection information; if yes, executing S310; if not, S309 is performed.

S309, sending out a scram switch connection signal to the overhaul device.

If the emergency stop switch box corresponding to the well is not connected to the control cabinet, the emergency stop switch box corresponding to the well indicates that the safety loop and the main switch cannot be guaranteed to be in a normal state, and an emergency stop switch connection signal can be sent to the overhauling device so as to prompt a user or a worker to access the emergency stop switch box corresponding to the current well to the control cabinet.

S310, controlling the overhaul device to perform fault detection.

In the first case, the service device is located outside the hall, and then fault detection can be performed when the first position and the second position are identical.

In the second case, when the first position is consistent with the second position, the maintenance device is located in the well, if the emergency stop switch box corresponding to the well is connected to the control cabinet, the safety loop and the main switch can be guaranteed to be in a normal state, and then the maintenance device can be controlled to perform fault detection.

In an alternative embodiment, after the controlling the overhauling device to perform fault detection, the method further comprises: acquiring an operation instruction of an elevator; when the operation instruction is that the express train operates, judging whether the first position and the second position are both outside the hall; if yes, controlling the elevator to run. This is because elevator car operation is a safety hazard when overhauling the top or bottom pit position of an elevator.

In order to clearly illustrate the connection modes of the overhaul device, the control cabinet and the electric appliance box when the overhaul device is at different positions, the following examples and the accompanying drawings are used for illustration.

Example one, the service apparatus is used outside of a hall.

FIG. 6 is a schematic diagram of the connection of the service device when in use outside the hall; as shown in fig. 6, the car roof and the pit are respectively provided with a first scram switch box 21 and a first scram switch box 22, and at the car roof portion, the first scram switch box 21 is connected with an electric box 23 of the car roof, and both the electric box 22 and the electric box 23 are connected with the control cabinet 2. In the pit part, the second emergency stop switch box 22 is connected with an electric box 24 of the pit, in the outer part of the hall, the common module 11 and the brake release control module 121 in the overhaul device 1 are connected with the control cabinet 2 through the first interface 13, the main switch control module 120 is connected with the control cabinet 2 through the second interface 14, and the speed limiter control module 122 is connected with the speed limiter 25 through the third interface 15 so as to control the speed limiter 25. At this time, the control cabinet 2 receives only the overhaul information of the position outside the hall. When the selection button is arranged on the overhaul device 1, the button corresponding to the overhaul outside the hall is selected, so that the functions of overhaul operation control and scram switch outside the hall can be realized.

It should be noted that, the control cabinet is provided with a plurality of interfaces, and the interfaces are used for providing a control signal for switching on and off for the main circuit breaker of the control cabinet, and connecting the direct current power supply, the communication circuit, the maintenance operation control circuit and the emergency stop switch safety circuit to the electrical box of the well. For the communication loop, each interface may be connected in parallel to the same communication interface of the main control board in the control cabinet, and for the judgment of different positions, the judgment may be distinguished by different communication protocols of the overhaul device, or each interface may be connected to different communication interfaces of the main control board of the control cabinet, which is not limited.

The second example is that the maintenance device is used on the car roof.

Fig. 7 is a schematic diagram of a connection mode of the maintenance device when the car roof is in use; as shown in fig. 6, the original car roof and pit are respectively provided with a first emergency stop switch box 21 and a first emergency stop switch box 22, and as shown in fig. 7, when the overhaul device 1 is used on the car roof, the shared module 11 of the overhaul device 1 is connected with the electric box 23 of the car roof through the first interface 13, and the outdoor overhaul module 12 is in an invalid state. The second emergency stop switch box 22 is connected with an electric box 24 of the pit at the pit part, the first emergency stop switch box 21 originally installed on the car roof is connected with the control cabinet 2 at the outer part of the hall, and the speed limiter 25 is not connected. At this time, the control cabinet 2 only receives maintenance information of the position of the car roof.

Specifically, the electric box 23 of the car roof is connected with the interface of the control cabinet 2 through a travelling cable, and a direct-current power supply, a communication loop, a maintenance operation control loop and a car roof emergency stop switch safety loop are connected to the interface of the electric box of the car roof through the interfaces. When the maintenance device 1 is used on the car roof, the emergency stop switch of the emergency stop switch box 21 is pressed first, the elevator safety circuit is disconnected, and the emergency stop switch box 21 is detached.
