With the development of social economy, the requirements of people on life quality are higher and higher, and the elevator is taken as a public transportation device which is very convenient in life of people and is popularized to middle and high-rise buildings and markets. According to statistics, the number of the elevators produced in China in 2020 reaches 105 thousands, and the remaining capacity of the elevators breaks through 800 thousands. The elevator enables people to go up and down floors more conveniently, and becomes indispensable riding instead of walk equipment and transportation equipment in people's daily life.
In the using process of the elevator, the central control program of the elevator is often required to be upgraded and maintained, and the functions of the elevator are maintained and perfected, wherein one common and convenient upgrading method is to upgrade the main control program of the elevator by a remote upgrading method. The remote upgrade method of the elevator main control program requires the writing of upgrade data by means of a Data Transfer Unit (DTU). However, if the size of the upgrade data exceeds the capacity of the DTU, the remote upgrade of the elevator main control program cannot be completed by the DTU at once.
The invention provides a segmented upgrading method and a segmented upgrading system for an elevator main control program, which are different from the traditional elevator main control program upgrading method which solves the problem that the remote upgrading of the upgrading data of a large memory is difficult to realize.
The method and the system for sectionally upgrading the elevator main control program provided by the embodiment of the invention are described in detail below with reference to the attached drawings, and firstly, the method for sectionally upgrading the elevator main control program provided by the embodiment of the invention is described with reference to the attached drawings.
Referring to fig. 1, an embodiment of the present invention provides a method for upgrading an elevator master control program in a segmented manner, and the method for upgrading an elevator master control program in a segmented manner in an embodiment of the present invention may be applied to a terminal, a server, software running in a terminal or a server, or the like. The terminal may be, but is not limited to, a tablet computer, a notebook computer, a desktop computer, and the like. The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a network service, cloud communication, middleware service, a domain name service, a security service, a Content Delivery Network (CDN), a big data and artificial intelligence platform, and the like. The elevator main control program subsection upgrading method in the embodiment of the invention mainly comprises the following steps:
s101, initiating an upgrading request;
specifically, the upgrade request includes version information and an acquisition path of the upgrade data.
Referring to fig. 2 and 3, the sectional upgrading of the elevator main control program is completed by the cooperation of the remote monitoring server, the remote upgrading server, the DTU wireless remote monitoring and the elevator main control. When the upgrading task starts, an upgrading request is firstly sent to the DTU wireless remote monitoring through the remote monitoring server, so that the DTU responds to the upgrading request and establishes connection with the remote upgrading server.
The DTU is used for converting the serial port data into the IP data or converting the IP data into the serial port data and transmitting the serial port data through a wireless communication network. The DTU internally integrates a TCP/IP protocol stack. The DTU keeps connection with the remote monitoring server according to the TCP of the remote monitoring server.
Each upgrade request initiated by the remote monitoring server comprises a unique upgrade task ID, the upgrade task ID comprises an acquisition path (package serial number of the upgrade data) of the upgrade data, and the DTU needs to attach the upgrade task ID to acquire the specified upgrade data when establishing connection with the remote upgrade server every time, so that errors of the upgrade data acquired by the DTU are prevented.
S102, obtaining upgrading data according to the upgrading request;
specifically, after receiving an upgrade request sent by the remote monitoring server, the DTU verifies the upgrade request and feeds back a verification result to the remote monitoring server. If the verification is passed, identifying the information of the remote upgrade server contained in the upgrade request through the DTU, and establishing TCP connection between the DTU and the remote upgrade server.
S102 may be further divided into the following steps S1021-S1023:
step S1021, checking the upgrading request, and judging whether the upgrading request meets the upgrading requirement;
according to step S101, the upgrade request includes version information and an acquisition path of the upgrade data. In particular, it is checked whether the version information matches the elevator master. Wherein the version information includes a program version, a program size, and an upgrade section of the upgrade data. And after receiving the upgrading request sent by the remote monitoring server, the DTU verifies the upgrading request, and judges whether the program version, the program size and the upgrading section of the upgrading data are matched with the elevator master control, so as to judge whether the upgrading request meets the upgrading requirement.
Step S1022, if the upgrade request meets the upgrade requirement, establishing connection with the upgrade data according to the acquisition path;
specifically, if the program version, the program size and the upgrading section of the upgrading data are matched with the elevator master control, the upgrading request meets the upgrading requirement, the DTU feeds back the acceptance of the upgrading request to the remote monitoring server, and the remote monitoring server prompts the DTU to respond to the upgrading request according to the feedback.
The DTU identifies the information of the remote upgrade server contained in the upgrade request, judges whether the IP port is consistent with the port used for current connection, and directly initiates a handshake instruction to the remote server to establish connection if the IP port is consistent with the port used for current connection; if not, the TCP connection between the DTU and the remote upgrade server is newly established.
On the other hand, if the program version, the program size and the upgrading section of the upgrading data are not matched with the elevator main control, the upgrading request does not meet the upgrading requirement, the DTU rejects the upgrading request and feeds back the rejected upgrading request to the remote monitoring server, and the remote monitoring server prompts that the upgrading request fails according to the feedback.
And step S1023, acquiring the upgrading data through connection.
Specifically, step S101 shows that the DTU establishes a connection with the remote upgrade server according to the upgrade task ID in the upgrade request, and acquires the specified upgrade data according to the acquisition path of the upgrade data in the upgrade task ID, thereby preventing the upgrade data acquired by the DTU from being in error.
S103, when the upgrade data exceeds the maximum capacity or is acquired completely, the acquisition of the upgrade data is suspended, and the upgrade data is written into an elevator main control;
specifically, the DTU needs to acquire the upgrade data first and then write the upgrade data into the elevator master control. It will be appreciated that when the size of the upgrade data exceeds the maximum capacity of the DTU, the DTU cannot complete the acquisition of the upgrade data in a single pass. In the embodiment of the invention, when the upgrading data fills the capacity of the DTU or the acquisition is completed, the DTU can automatically suspend the acquisition of the upgrading data, disconnect with the remote upgrading server and start to write the stored upgrading data into the elevator master control. The DTU can acquire the state of the elevator when writing the upgrade data into the elevator master control, and adjust the writing speed of the upgrade data written into the elevator master control according to the state of the elevator.
S103 may be further divided into the following steps S1031-S1033:
step S1031, obtaining the state of the elevator, and judging whether the elevator is in a maintenance state;
specifically, the DTU initiates a remote Bootloader request to the elevator master control, the elevator master control enters a remote Bootloader auditing state after receiving the remote Bootloader request, and the remote Bootloader is operated after the remote Bootloader auditing is passed. By operating the remote Bootloader, the preparation work of writing the upgrade data is completed while the elevator master control initialization is completed.
When the DTU writes the saved upgrade data into the elevator master control, the DTU firstly acquires the state of the elevator, judges whether the elevator is in a maintenance state, and adjusts the writing speed of the upgrade data according to whether the elevator is in the maintenance state.
Step S1032, if the elevator is in a maintenance state, writing the upgrade data into an elevator main control at a first writing speed;
and step S1033, if the elevator is not in the maintenance state, writing the upgrade data into the elevator main control at a second writing speed.
Wherein the second writing speed is less than the first writing speed.
Specifically, the 485 bus connected with the DTU and the elevator master control has communication data related to a remote monitoring function, and because the communication data cannot be terminated when the upgrade data is written in, a strict communication time sequence needs to be kept when the upgrade data is written in through the RS 485. When the elevator is in a maintenance state, the communication data does not need to send a fault report, and when the elevator is not in the maintenance state, the fault report needs to be sent, so that the byte number of each packet of data of the upgrade data is increased when the elevator is in the maintenance state. In the embodiment of the invention, if the elevator is in a maintenance state, the DTU writes the upgrade data into the elevator main control at the speed of 256 bytes per packet of data; if the elevator is not in maintenance, the DTU writes the upgrade data to the elevator master at a rate of 16 bytes per packet of data.
When the DTU writes the data packet of the upgrade data into the elevator main control, each packet of data comprises the address of data writing, and the elevator main control writes the data packet into a corresponding position according to the address of data writing.
In the embodiment of the invention, in the writing process of the upgrade data, the elevator master control checks the content of the upgrade data, and the DTU judges whether the stored upgrade data is completely written in real time. And after the upgrade data stored by the DTU is completely written into the elevator master control, the DTU empties the stored upgrade data and judges whether the upgrade data is completely acquired or not again.
S104, judging whether the upgrade data is completely acquired or not, and if the upgrade data is not completely acquired, returning to the step of acquiring the upgrade data according to the upgrade request;
specifically, after the upgrade data stored by the DTU is completely written into the elevator master control, the DTU clears the stored upgrade data and judges whether the upgrade data is acquired or not again. If the upgrade data is not acquired, returning to the step S102, and establishing the connection with the remote upgrade server again through the upgrade task ID; if the upgrade data acquisition is completed, whether the upgrade of the elevator main control program is completed or not needs to be verified.
In the embodiment of the invention, the DTU is reconnected with the remote upgrade server through the upgrade task ID, and judges whether the upgrade data is acquired according to the acquisition path of the upgrade data contained in the upgrade task ID; when the upgrade data is not completely acquired, the DTU continues to acquire the rest upgrade data from the remote upgrade server, and when the upgrade data exceeds the self maximum capacity or the acquisition is completed, the DTU suspends the acquisition of the upgrade data and continues to execute the steps S102-S104.
And S105, if the upgrade data is obtained completely, feeding back that the elevator master control program upgrade is completed.
Specifically, the DTU initiates a cyclic redundancy check, such as a CRC32 check, to the elevator master, the elevator master performs the cyclic redundancy check according to the program information, and if the check passes, the DTU is fed back that the check has passed. And the DTU replies the completion of the elevator master control upgrading to the server according to the feedback information that the elevator master control cyclic redundancy check passes, and finishes the upgrading task to complete the elevator master control program sectional upgrading.
S105 may be further divided into the following steps S1051-S1052:
and S1051, if the upgrade data is acquired, checking whether the upgrade is finished with the elevator master control.
Specifically, when the upgrade data is acquired, the DTU suspends the acquisition of the upgrade data, writes the acquired upgrade data into the elevator master control, and judges whether the stored upgrade data is completely written into the elevator master control in real time. And after the upgrade data stored by the DTU is completely written into the elevator master control, the DTU clears the stored upgrade data, judges whether the upgrade data is acquired completely or not again, and verifies whether the program upgrade is completed with the elevator master control or not.
In an embodiment of the invention, the elevator master sets the upgrade complete flag after the upgrade data is completely written to the elevator master. And judging whether the upgrade data is completely written into the elevator master control through cyclic redundancy check according to the upgrade completion flag.
And step S1052, if the elevator master control is upgraded, feeding back that the elevator master control program upgrading is finished.
Specifically, the DTU replies the completion of the elevator master control upgrading to the server according to the feedback information that the elevator master control cyclic redundancy check passes, and ends the upgrading task to complete the elevator master control program subsection upgrading.
Next, an elevator main control program subsection upgrading system provided according to an embodiment of the application is described with reference to the attached drawings.
