All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
The terms "first," "second," "third," and "fourth" and the like in the description and in the claims and drawings are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion.

Elevators are widely used in various situations. The main control program of the elevator can adjust various operation parameters of the elevator, thereby monitoring and controlling the overall operation condition of the elevator. Therefore, technicians need to upgrade the main control program of the elevator to improve the operation safety and reliability of the elevator. In the related art, a main method for upgrading a main control program of an elevator is manual upgrading, and specifically comprises the following steps: when the main control program needs to be upgraded, a technician manually goes to the place where the elevator is located, the elevator is stopped, professional equipment is used for burning the upgrade program of the main control program to the elevator when the elevator is stopped, and the elevator can be restored to normal operation after the burning is completed. The method for upgrading the elevator main control program needs to spend more time for technicians, and needs to stop when upgrading, thereby affecting the normal operation of the elevator.
Therefore, in order to solve the above problems, the embodiment of the application provides an upgrade method for an elevator main control program, which can upgrade the elevator main control program without stopping and without manual operation.
Fig. 1 is a flowchart of an upgrade method of an elevator main control program according to an embodiment of the present application, where, as shown in fig. 1, the upgrade method of an elevator main control program according to an embodiment of the present application includes:
s101, receiving an upgrade request.
In step S101, an upgrade request is sent from the data transmission unit, including the program type and version of the upgrade program. The upgrade program is a new main control program which is obtained by technical management personnel after analyzing the data of the elevator running condition and can improve the elevator running performance or the elevator running safety, and the main control program of the elevator is upgraded into a safer and more stable main control program in a similar system updating mode. The upgrade program thus has different version numbers for indicating the version of the upgrade program and different types for displaying the model numbers of the different elevators to which the upgrade program is applicable.
S102, judging whether the upgrading request meets the upgrading requirement.
And S103, if the upgrade request meets the upgrade requirement, feeding back to the data transmission unit to allow the upgrade.
S104, receiving an upgrade program.
It should be noted that, in this embodiment, the upgrade program is received in packets, that is, the complete upgrade program is divided into a plurality of data packets with different sizes and numbered, and then each data packet is transmitted and received according to the numbered sequence. The sub-packet transmission program has the advantages that larger program sub-packets can be transmitted and received, occupied transmission bandwidth is reduced, when data packets are damaged due to unstable transmission, the current data packets can be retransmitted in time, and the stability of transmission of an upgrade program is improved.
In step S104, the upgrade program is sent from the data transmission unit, wherein the rate of receiving the upgrade program is increased to 256 bytes per packet when the elevator is in the maintenance state, and the rate of receiving the upgrade program is decreased to 16 bytes per packet when the elevator is not in the maintenance state. When the elevator is in the overhauling state, the elevator is not running. Thus, the rate of receiving the upgrade program can be increased, and when the elevator is in a running state, a higher rate of receiving the upgrade program can affect the running of a normal elevator, so that the rate of receiving the upgrade program can be reduced. Through practical tests and calculation, when the elevator is in a running state, the rate of receiving the upgrade program is 16 bytes per packet, which is the maximum rate which does not affect the normal running of the elevator.
S105, checking the received upgrading program, and if the received upgrading program passes the check, feeding back the received upgrading program to the data transmission unit to determine that the upgrading is successful.
Optionally, verifying the received upgrade program in step S105 includes: and performing CRC (cyclic redundancy check) on the starting address and the length of the upgrading program, and deleting the upgrading program and re-receiving the upgrading program if the starting address and the length of the upgrading program do not pass the CRC.
The upgrade method of the elevator main control program provided by the embodiment has the beneficial effects that: by judging whether the upgrade request meets the upgrade requirement after receiving the upgrade request, if the upgrade request meets the upgrade requirement, the main control program is upgraded, so that the elevator main control program is upgraded without a technician going to the elevator, meanwhile, the speed of receiving the upgrade program is improved when the elevator is in a maintenance state, the speed of receiving the upgrade program is reduced when the elevator is not in the maintenance state, the speed of receiving the upgrade program is flexibly adjusted according to different states of the elevator, and the influence of the upgrade main control program on the normal operation of the elevator is reduced.
Optionally, as shown in fig. 2, the specific way to check the received upgrade program in this embodiment is:
s201, checking the data packet of the current upgrading program.
In step S201, the verification of the data packet of the current upgrade program specifically includes: each time a packet of data is received, a check is made on that packet.
S202, after the data packet of the current upgrading program passes the verification, feeding back the data packet of the current upgrading program to the data transmission unit, and passing the verification.
In step S202, after the data packet of the current upgrade program passes the verification, the data packet fed back to the data transmission unit passes the verification, and the data transmission unit receives the information that the data packet of the current upgrade program passes the verification and then sends the next data packet, and the above operations are repeated.
S203, receiving a data packet of the next upgrading program.
Optionally, as shown in fig. 3, determining whether the upgrade request meets the upgrade requirement in the embodiment includes:
s301, judging whether a main control program corresponding to the program type of the upgrade program is being upgraded.
The function of judging whether the main control program corresponding to the program type of the upgrade program is being upgraded is to prevent the current main control program from being repeatedly upgraded under the condition of being upgraded.
S302, if the judgment result of the step S301 is yes, judging whether the program version of the upgrade program is consistent with the version of the current main control program.
The function of judging whether the program version of the upgrading program is consistent with the version of the current main control program is to prevent the main control program of the old version from replacing the main control program of the new version to upgrade, so that the performance and the safety of the elevator are degraded.
S303, if the judgment result in the step S302 is negative, determining that the upgrading request meets the upgrading requirement.
Through step S303, it is explained that the type of the main control program to be upgraded is consistent with the elevator, the elevator is not currently being upgraded, and the main control program to be upgraded is the main control program of the updated version, so that it can be determined that the upgrade request meets the upgrade requirement.
The above description describes the data interaction transmission between the elevator master control and the data transmission unit, and the following description describes the connection and data interaction situation between the data transmission unit and the external server.
Optionally, the data transmission unit in the application maintains a TCP connection with the server, and the data transmission unit receives the upgrade request from the server and sends the upgrade request to the elevator master control. The server comprises a remote monitoring server and a remote upgrading server.
Based on the TCP connection between the data transmission unit and the server in the above embodiment, the present application proposes another method for upgrading the elevator main control program, specifically, as shown in fig. 4:
s401, receiving upgrade information sent by a server.
In step S401, the upgrade information includes an upgrade program, an upgrade program version, an upgrade program size, and an upgrade section of the current upgrade.
S402, confirming whether the version, the size and the ascending section of the upgrading program are matched with the elevator, and if so, checking the upgrading program.
It should be noted that, the verification of the upgrade procedure in step S402 specifically includes: the data transmission unit receives the upgrade program in a subpacket mode, checks the data packet once after receiving the data packet of the upgrade program, if the data packet passes the check, the next step is carried out, and if the data packet does not pass the check, the current data packet is deleted and then the current data packet is received again.
S403, if the verification is passed, the upgrade request is sent to the elevator master control.
Optionally, the upgrade data includes address information of the server, and after the verification in step S403 is passed, the method further includes: and establishing a new TCP connection channel with the server according to the address information of the server, wherein the new TCP connection channel is used for transmitting the upgrade program. The function of establishing a new TCP connection channel in this embodiment is to transmit an upgrade program by a dedicated channel, so that other data transmission between the data transmission unit and the server is not interfered, and stability of transmission of the upgrade program is improved.
The above description describes the data interaction method and steps between the data transmission unit and the server of the present application, and the following describes the specific relationship between the data transmission unit, the remote monitoring server and the remote upgrading server. As shown in fig. 5:
the remote monitoring server is controlled by a technician, sends a signal for requesting upgrading to the data transmission unit (Data Transform Unit, DTU), and the Data Transmission Unit (DTU) responds to the signal and then is newly connected with a TCP link to connect to the remote upgrading server, so that a connection channel between the Data Transmission Unit (DTU) and the remote upgrading server is established. The remote upgrade server then issues the data packet of the upgrade program to a Data Transmission Unit (DTU), which receives the data packet of the upgrade program.
Fig. 6 is a data connection diagram of each main body of an upgrade method of an elevator main control program according to an embodiment of the present application. As shown in fig. 6, the remote monitoring server and the remote upgrading server are both connected with a Data Transmission Unit (DTU) in a 2G or 4G wireless network, and the Data Transmission Unit (DTU) is connected with an elevator master control by an RS 485. The RS485 connection is a standard connection mode for balancing the electrical characteristics of a driver and a receiver in a digital multipoint system, can effectively transmit signals under a remote condition and an environment with large electronic noise, and can connect a local network and a multi-branch communication link.
It should be noted that, the connection relationships between the remote monitoring server, the remote upgrading server, the Data Transmission Unit (DTU) and the elevator master control in the present application include, but are not limited to, the connection relationship shown in fig. 5, and other types of connection manners or connection relationships belong to the connection relationships between the remote monitoring server, the remote upgrading server, the Data Transmission Unit (DTU) and the elevator master control in the present application, which is not unduly limited in this specification.
