Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
In order to more clearly introduce the technical solutions provided by the embodiments of the present application, an application scenario of the embodiments of the present application is described next.
For the control of the elevator, a corresponding driving control command is generally sent to a driving device of the elevator car through an elevator main board (namely, a control device of the elevator), so as to drive the elevator to run. The elevator mainboard is supporting with elevator car and elevator car's drive arrangement, and in the supporting facility of different elevator producer productions, because the specification of elevator is different, be distinguished on the control mode, for example: some elevator cars are provided with a front door and a rear door, an elevator entering car passes through the front door, an elevator exiting car passes through the rear door and the like; the ladder-controlled negative layer, etc. are all different.
Based on this, an embodiment of the present application provides an intelligent elevator gateway, please refer to fig. 1, fig. 1 is a functional structure block diagram of an intelligent elevator gateway 100 provided in the embodiment of the present application, and as shown in fig. 1, the intelligent elevator gateway 100 includes an input device 101, a memory 102, and a processor 103.
The input device 101 is used for receiving a first code format corresponding to call information of a target elevator input by a user. A memory 102 for storing the first encoding format. The processor 103 is used for decoding the call signal according to a second coding format corresponding to the call signal stored in advance when receiving the call signal aiming at the target elevator, and obtaining the call information corresponding to the call signal; and the calling information is coded according to a first coding format and then sent to an elevator main board corresponding to the target elevator, so that the elevator main board can control the target elevator according to the calling information.
As a possible implementation, the input apparatus 101 may include a peripheral interface for coupling various input devices to the processor 103 and the memory 102, and an input device. In some embodiments, the peripheral interface, processor 103 may be implemented in a single chip. In other examples, they may be implemented separately from separate chips. The input device is used to provide input data to the user to enable the user to interact with the intelligent elevator gateway 100. The input device 101 may be various external devices, such as various electronic devices; or may be an input device, such as a display screen, etc., provided in the intelligent elevator gateway 100 itself. Corresponding to the user establishing a connection with a peripheral interface through an input device to enable the input of configuration information into the intelligent elevator gateway 100.
As another possible implementation, the input device 101 may be a virtual network input module, and the user input of the first encoding format may be implemented by a Domain Name System (DNS) in which the intelligent elevator gateway 100 is located, where the domain name system is a service of the internet. It acts as a distributed database that maps domain names and IP addresses to each other, enabling people to more conveniently access the internet. For the intelligent elevator gateway 100, there is a specific IP address and domain name from which the distributed database can be accessed and then set in the first encoding format. The setting belongs to virtual network setting, and actually does not carry out domain name correlation with other equipment of an elevator system, so that the intelligent elevator gateway 100 can be in communication butt joint with an elevator main board corresponding to the set first coding format. For example, now there is an elevator main board with a code format a and another elevator main board with a code format B, and assuming that the current intelligent elevator gateway 100 needs to be used for interfacing with the elevator main board with a code format a, the user sets and stores the code format a on the intelligent elevator gateway 100. Assuming that the intelligent elevator gateway 100 needs to be used for interfacing with an elevator main board with the code format B currently, the user can set the code format B on the intelligent elevator gateway and store the set code format B.
It is to be noted that the target elevator can be understood as an elevator which the intelligent elevator gateway 100 needs to control. In the embodiment of the application, at least one intelligent elevator gateway 100 is arranged in each elevator, so that the communication between the intelligent elevator gateway 100 and the elevators is not disordered even in the case of a plurality of elevators. When applied to the companion control of elevators, the corresponding intelligent elevator gateways 100 of each elevator can be distinguished by a number.
Further, the information set on the intelligent elevator gateway 100 may include: the elevator number, the negative layer for setting elevator control of the bridge, the elevator number for setting back display elevator control and bridge elevator control, the front door and the rear door of the destination door, which door is opened by the elevator, and the like. It should be noted that the call information of the target elevator corresponds to the first code format set on the intelligent elevator gateway 100, and only the call information corresponding to the target elevator can enable the elevator main board to complete the control of the elevator, so it can be understood that, if the first elevator has only one front elevator door and the second elevator has both a front elevator door and a back elevator door, the call information of the first elevator is different from the call information of the second elevator, the call information of the first elevator does not relate to the selected front and back doors, and the call information of the second elevator relates to the selected front and back doors.
For the first encoding format: for example, assuming the call information contains a total of 5 pieces of information, the first code format may be used to indicate the location of the 5 pieces of information in the code, such as "info 1; information 2; information 3; information 4; information 5 "is in an encoded format; "information 5; information 4; information 3; information 2; information 1 "is another encoding format. The first encoding format may also be used to represent the respective fields of the 5 messages, such as message 1 represented by binary encoding; information 2 is represented by english letters; the information 3 is represented by a number, etc. The first code format may also be used to indicate the total number of information contained in the call information, such as if only four field codes are provided in the first code format, indicating that only four information need be contained in the call information. Of course, since the encoding method of the information of each elevator is known when the elevator is shipped from the factory, the user can directly set the information in the intelligent elevator gateway 100 according to the encoding method corresponding to the elevator.
The Memory 102 may include, but is not limited to, Random Access Memory (RAM), Read Only Memory (ROM), Programmable Read Only Memory (PROM), Erasable Read Only Memory (EPROM), electrically Erasable Read Only Memory (EEPROM), and the like.
The processor 103 may be an integrated circuit chip having signal processing capabilities. The Processor may be a general-purpose Processor, including a Central Processing Unit (CPU), a Network Processor (NP), and the like; but may also be a digital signal processor, an application specific integrated circuit, an off-the-shelf programmable gate array or other programmable logic device, discrete gate or transistor logic, discrete hardware components. Which may implement or perform the methods, steps, and logic blocks disclosed in the embodiments of the present application. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
When the processor 103 receives a call signal for a target elevator, the call signal is decoded in a second code format corresponding to the call signal. It will be appreciated that a second encoding format may be pre-stored on the memory 102, and that upon receipt of a call signal, the processor 103 decodes the call signal according to the stored second encoding format, the call signal being encoded and packaged according to the second encoding format, so that upon decoding, the call signal may likewise be decoded using the second encoding format. For example, assuming that the call signal is "field 1, field 2, field 3, field 4", each field represents a call information in the second code format, e.g., field 1 is an elevator number, the field content is assumed to be "0001", the field format is 16-ary, and then by decoding, the elevator number 2 can be obtained; the other fields work the same. After decoding is carried out according to the format of the fields and the corresponding content and the second coding format, the call information corresponding to each field can be obtained, and further all the call information contained in the call signal can be obtained.
It is noted that for the second encoding format, it may be defined by the user at the factory shipment of the intelligent elevator gateway 100 and then stored in the memory 102.
After obtaining call information, it will be appreciated that the user typically initiates a call request through a terminal, but the user does not know the specific model or parameters of the elevator to be called, and thus some of the call information in the call signal may be for some elevator models or parameters that are prevalent, and the call information may not match the target elevator. If the calling information is directly sent to the elevator main board, the elevator main board receives the calling information which is not matched with the target elevator, and the calling information can be taken as error information or invalid information without further processing, so that the whole calling process cannot be completed. The intelligent elevator gateway 100 is already configured with a first coding format corresponding to the call information of the target elevator by the user, and the processor 103 packages and codes the call information again according to the first coding format, it can be understood that, because the first coding format and the second coding format are different, for example, fields contained in the first coding format may be less than fields contained in the second coding format, when the codes are packaged again, the processor 103 only extracts fields required in the first coding format; for another example, the fields contained in the first code format may be the same as the fields contained in the second code format, but the specific field format is different, then when the codes are packaged again, the processor 103 will convert the call information to the fields corresponding to the first code format; for another example, the first encoding format may contain more fields than the second encoding format, and then the processor 103 directly leaves the vacant fields in the second encoding format empty when encoding is packed again. In any case, by decoding and then re-encoding, call information can be obtained that can be used to control the target elevator.
And after the elevator mainboard receives the calling information, controlling the target elevator according to the calling information. The call information may include: elevator number, starting floor, terminal floor, front and rear doors of elevator, etc. For the elevator main board, the elevator number is corresponding to the target elevator, and a corresponding control instruction is generated according to call information related to control, such as a starting floor, a terminal floor, front and rear doors of the elevator, and the like, and then is output to a driving device of the target elevator, so that the call of the target elevator can be completed.
Compared with the prior art, the intelligent elevator gateway 100 provided by the embodiment of the application has configurability, and can store a first coding format defined by a user and corresponding to call information of a target elevator; and the data (namely call information) corresponding to the second coding format is converted into the first coding format, so that compatibility among different coding protocols is realized, and the reliability of elevator control is improved. In addition, because the intelligent elevator gateway 100 is configurable, the intelligent elevator gateway can be suitable for controlling elevators of different models only by user configuration, so that the intelligent elevator gateway is more flexible.
For the intelligent elevator gateway 100 provided in the embodiment of the present application, in practical applications, an elevator control system can be formed by matching a call device (for initiating a call signal), and the elevator control system provided in the embodiment of the present application will be introduced by combining the intelligent elevator gateway 100 in the following.
Referring to fig. 2, an elevator control system 200 according to an embodiment of the present application is provided, where the elevator control system 200 includes an intelligent elevator gateway 100 and a call device 300, and the elevator control system 200 is configured to control a target elevator. In the elevator control system 200, the call device 300 is used to transmit a call signal of a target elevator to the intelligent elevator gateway 100. The intelligent elevator gateway 100 is used for receiving the call signal and decoding the call signal according to a second coding format corresponding to the call signal stored in advance to obtain call information corresponding to the call signal; and the calling information is coded according to a first coding format corresponding to the calling information of the target elevator and then sent to an elevator main board corresponding to the target elevator, so that the elevator main board can control the target elevator according to the calling information.
It should be noted that the intelligent elevator gateway 100 described in the foregoing embodiments is configurable, and it should be understood that the configuration is performed after the target elevator to be corresponded is determined. However, in practical applications, the target elevator corresponding to the intelligent elevator gateway 100 may be determined at the time of factory shipment, that is, the first encoding format may be stored in the intelligent elevator gateway 100 at the time of factory shipment, and the elevator control system 200 may be directly used for controlling the target elevator. In addition, the encoding formats of target elevators of various models can be stored, and when the elevator is used by a user, the encoding format corresponding to the target elevator only needs to be selected from the existing encoding formats as the first encoding format.
Referring next to fig. 3, it is a schematic structural diagram of a call device 300 provided in the embodiment of the present application, and as shown in fig. 3, the call device 300 includes a doorway host computer 301 and a landing reading head 302. Wherein, the doorway main machine 301 is arranged outside the car of the target elevator and is equivalent to an external calling device; the hall probe 302 is provided in the car of the target elevator and corresponds to an inner call device.
Correspondingly, the intelligent elevator gateway 100 further includes a receiving device for receiving the call signal transmitted by the call device 300, and the receiving device may receive an external call signal transmitted by an external call device or an internal call signal transmitted by an internal call device. For the internal call signal and the external call signal, both belong to the call signal, and in order to reduce the working pressure of the intelligent elevator gateway 100, the coding formats of the internal call signal and the external call signal are the second coding format. By the arrangement mode, the encoding modes of the data sent between the call devices 300 and the intelligent elevator gateway 100 are uniform, and the working pressure of the intelligent elevator gateway 100 is reduced.
In addition, for the second coding format, after the intelligent elevator gateway 100 and the call device 300 are determined, the second coding format can be determined directly according to a common protocol coding mode between the intelligent elevator gateway 100 and the call device 300. For example, the second code format includes all of the fields of the call information that are available for selection, and the format of each field may be a relatively common format. Through the implementation mode, the call information related to the field in the second coding format is the most comprehensive, and when the call information is converted into the first coding format, the format conversion is only carried out after the field of the call information corresponding to the target elevator is screened.
For the doorway host 301, the doorway host 301 and the intelligent elevator gateway 100 are arranged in one domain, and can be arranged in the form of a host and an extension, which are in the same domain, so as to realize data exchange in the domain. Each extension set can send a call signal to the intelligent elevator gateway 100, and the host computer can also send a call signal to the intelligent elevator gateway 100. The doorway host 301 is configured to receive an external call request sent by the first user terminal, encode the external call request according to a second encoding format, and generate an external call signal. The first user terminal is understood to be a user terminal outside the car of the target elevator. For example: when a user wants to call in advance at home, the user can initiate an elevator call advance request through the first user terminal. The first user terminal may be a mobile phone, a computer, a video phone, or the like of a user. Taking a videophone as an example, the videophone is generally connected with an entrance guard host of a cell, so that visitors and the like can be seen, the videophone and the entrance host 301 can also be added into the same domain name system, and then a user can finish calling in advance on the videophone. If the calling party is a computer, a mobile phone or the like, the calling party can establish communication connection with the portal host 301 in the form of software, WeChat public numbers, WeChat applets or the like to call in advance. After receiving the call request, the doorway host 301 processes the call request to generate an outbound signal, and then sends the outbound signal to the intelligent elevator gateway 100, so that the intelligent elevator gateway 100 performs subsequent processing.
In addition, in order to relieve the pressure on the door host 301, in which different users may make calls at the same time, the call device 300 may further include an exchange for receiving call requests sent by at least two different user terminals and sending the call requests sent by at least two different user terminals to the door host 301. The data transfer is realized through the switch, and the disorder of the data is avoided.
The elevator control read head 302 is provided inside the car, and receives the inside call request transmitted from the second user terminal, and codes the inside call request according to the second coding format to generate an inside call signal. The second user terminal is generally a mobile phone of the user because the second user terminal is inside the car.
