Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any inventive step, are within the scope of the present invention.
Fig. 1 is a schematic flow chart of a method for upgrading a multi-online program according to an embodiment of the present invention.
The embodiment of the invention provides a method for upgrading a multi-split program, which can be applied to equipment of a multi-split system, such as an air duct machine, a ceiling machine or a wall-mounted machine of the multi-split system, and comprises the following steps of S11 to S14:
s11, when the current equipment is judged to be source node equipment, reading a programming condition and an upgrading program written in advance from a memory of the current equipment; wherein the programming condition comprises an upgrade condition.
Specifically, it is first determined whether the current device is a source node device, and when it is determined that the current device is the source node device, the pre-written programming condition and the upgrade program are read from the memory thereof.
The source node device is a node device in the multi-split system, and programming conditions and an upgrading program are written in a memory of a main control chip in advance. In specific implementation, a node device most convenient for program programming may be manually selected in advance according to an actual installation location of the multi-split system, a programming condition and an upgrade program are written into the node device through a programmer, and the node device is used as a source node device for program upgrading.
There are various methods for determining whether the current device is a source node device, for example, determining whether the current device is a source node device by determining whether a pre-written programming condition and an upgrade program exist in a memory of a main control chip of the current device, or determining whether the current device is a source node device by setting a source node identifier in the programming condition in advance and subsequently determining whether a pre-written source node identifier exists in a memory of a main control chip of the current device. The embodiments of the present invention are not limited to these embodiments.
The upgrading conditions refer to the summary of the upgrading conditions that each node device needs to meet in the program upgrading process, and only the node devices that completely meet the upgrading conditions allow the program upgrading. In specific implementation, the upgrade condition may be set according to actual upgrade needs, for example, according to the node type of the node device or the node program version, and the flexibility is high, so that the upgrade process is more reasonable and controllable. Optionally, the upgrade condition includes at least one of a node type, a node capacity, and a node program version.
The programming conditions at least include upgrading conditions, and the programming conditions may also include conditions to be followed by the source node device in the program upgrading process, for example, the duration of the source node device broadcasting the upgrading conditions on the bus, or the manner in which the source node device sends the upgrading program, so as to further optimize the program upgrading process. In specific implementation, other contents except the upgrading condition in the programming condition can be set according to actual needs, and the beneficial effects of the invention are not influenced.
S12, broadcasting the upgrade condition on a communication bus of the multi-split system, so that when other node equipment connected to the communication bus monitors the upgrade condition, judging whether the other node equipment meets the upgrade condition, and returning corresponding reply information when the other node equipment meets the upgrade condition; wherein the reply information comprises a node address.
Specifically, taking the upgrade condition including the node type as an example, after reading the pre-written programming condition and the upgrade program, sending the upgrade condition to the communication bus of the multi-split system in a data packet manner, so as to continuously broadcast the upgrade condition within a certain time, when monitoring the upgrade condition, other node devices connected to the communication bus compare the node type of the device with the node type in the upgrade condition, thereby determining whether the device meets the upgrade condition, when determining that the node type of the device is consistent with the node type in the upgrade condition, the device meets the upgrade condition, and when determining that the upgrade condition is met, returns corresponding reply information, and enters the program upgrade state. After other node equipment connected to a communication bus of the multi-split system normally operates, information of the communication bus is monitored in real time.
Optionally, the reply information further includes a node type and a node capacity.
Further, the programming condition further comprises a continuous sending time length; the continuous sending time length is configured according to the longest communication time of the multi-split system;
the duration of the upgrade condition broadcast by the current device on the communication bus is equal to the duration of the continuous transmission time.
The maximum communication time of the multi-split system is the maximum time required for all the nodes on the communication bus of the multi-split system to send data once. By setting the duration of the upgrade condition broadcast by the current device on the communication bus to be equal to the continuous sending duration, the upgrade condition can be sent to all node devices on the communication bus, and meanwhile, the situation that the upgrade time consumption is increased due to the fact that the duration of the upgrade condition broadcast on the communication bus is too long can be effectively avoided.
And S13, receiving the reply information returned by the node equipment meeting the condition.
And if no other node equipment returns the reply information on the communication bus, all the node equipment needing to be upgraded is found by default, and the search is ended.
And S14, sending the upgrading program to the node equipment meeting the conditions according to the reply information, so that the node equipment meeting the conditions can upgrade the program according to the upgrading program.
After the search is finished, the upgrading program is sent to all the node devices meeting the conditions through the communication bus according to all the received reply information, so that all the node devices meeting the conditions receive the upgrading program and then store the upgrading program to an idle ROM (read only memory) area or an external memory for program upgrading.
Furthermore, the programming condition also comprises the length of a single data packet and the number of the data packets;
then, the sending the upgrade program to the node device meeting the condition according to the reply information specifically includes:
according to the length of the single data packet and the number of the data packets, performing sub-packet processing on the upgrading program to obtain a plurality of upgrading data packets;
and sending the plurality of upgrading data packets to the node equipment meeting the conditions according to the reply information.
The single packet length refers to a maximum packet length allowed when the source node device performs data transmission with other node devices. The number of packets is the number of packets that are obtained by packetizing the upgrade program, and specifically, the number of packets is ═ 1 (upgrade program total Byte size (Byte)/single packet length (Byte)).
The upgrading program is divided into a plurality of upgrading data packets according to the length of a single data packet and the number of the data packets in the programming condition, and then the plurality of upgrading data packets are sent to the node equipment meeting the condition through the communication bus according to the node address in the reply information. By dividing the upgrading program into a plurality of upgrading data packets and transmitting the upgrading data packets to the node equipment meeting the conditions, the data transmission efficiency between the source node equipment and other node equipment can be effectively improved, and the program upgrading efficiency is further improved.
Still further, the process of program upgrade by the node device meeting the condition according to the upgrade program specifically includes the steps of:
receiving and storing the plurality of upgrading data packets;
checking the plurality of upgrading data packets;
when the plurality of upgrading data packets are judged to pass the verification, program updating is carried out according to the plurality of upgrading data packets, and upgrading completion information is fed back to the current equipment after the program updating is completed;
and when judging that the plurality of upgrading data packets do not pass the verification, ending the program upgrading and restoring to the state before the program upgrading.
After receiving a plurality of upgrading data packets, the node equipment meeting the conditions stores the upgrading data packets into an idle ROM area or an external memory, checks the upgrading data packets after the transmission of the upgrading data packets is finished, updates programs according to the upgrading data packets when the upgrading data packets are judged to pass the checking, so that the node equipment finishes program upgrading and runs according to the updated programs, feeds back upgrading completion information to the current equipment after the program upgrading is finished, finishes program upgrading of the node equipment when the upgrading data packets are judged not to pass the checking completely, and restores the state of the node equipment to the state before the program upgrading, so that the node equipment still runs according to the state before the upgrading. By checking the received upgrading data packets, the accuracy of the upgrading data packets can be effectively ensured, and the accuracy of program upgrading is effectively ensured.
Optionally, after the program is upgraded, the node device shifts to a normal operation state, and continues to monitor bus information to prepare for upgrading again.
Furthermore, the upgrade data packet includes a checksum;
and the node equipment meeting the conditions checks the plurality of upgrading data packets by adopting a CRC (cyclic redundancy check) check mode.
The upgrading data packet is composed of a packet header, data and a checksum. After the node equipment meeting the conditions receives the upgrade data packet each time, firstly calculating the checksum of the currently received upgrade data packet, then comparing the checksum with the checksum in the upgrade data packet, if the checksum is consistent with the checksum in the upgrade data packet, correctly receiving the currently received upgrade data packet, and storing the data information in the currently received upgrade data packet; and if the updating data packet is inconsistent with the updating data packet, the currently received updating data packet is received wrongly, the currently received updating data packet is discarded, and the updating data packet is received again.
It should be noted that, the multi-split program upgrading method provided in this embodiment may be executed from the time when the current device is powered on through the BootLoader function, and the program upgrading state may be determined in advance before the chip of the current device normally works through the BootLoader function, so that preparation is made for program upgrading after the chip normally works.
The method for upgrading the multi-split program according to this embodiment will be better described with reference to the working timing sequence of the node device on the communication bus of the multi-split system.
Starting from power-on, each node device on a communication bus of the multi-split system first judges whether a node of the node device is a source node device.
If the node equipment is determined not to be the source node equipment, the node equipment enters a normal operation state and monitors bus information in real time, and once the upgrading condition is monitored and the node equipment is judged to meet the upgrading condition, the node equipment enters a program upgrading state and returns reply information. Receiving the upgrading data packet through the communication bus, storing the upgrading data packet, and after the transmission of the upgrading data packet is finished, checking the upgrading data packet: if the verification is correct, the node equipment operates according to the updated program, and feeds back upgrading completion information to the source node equipment; if the verification is wrong, the node equipment still operates according to the state before upgrading, and information is not fed back to the source node equipment. After the program is upgraded, the node equipment is switched to a normal operation state, and meanwhile, bus information continues to be monitored, so that preparation is made for upgrading again.
If the node device is determined to be the source node device, the node device enters a program upgrading state, broadcasts upgrading conditions to other node devices on the communication bus according to the read program upgrading conditions, and receives and records reply information returned by other node devices meeting the upgrading conditions. When the bus does not receive the reply information returned by the node equipment meeting the upgrading condition any more, the node searching is finished, the program upgrading state is entered, the upgrading data packet is sent to the bus one by one, after the upgrading data packet is sent, the node equipment meeting the upgrading condition is informed to finish sending, the upgrading completion information sent by the node equipment meeting the upgrading condition is received, the upgrading completion information is recorded, the upgrading process is finished, the source node equipment is recovered to be the common node equipment, the normal operation state is switched, and meanwhile, the bus information is monitored, and preparation is made for upgrading again.
It should be noted that, this embodiment depends on the characteristics of bus communication of a multi-split computer product, program upgrade can be realized in a bus programming mode without changing the design state of each node device, and program upgrade is performed by using wireless modules such as a WIFI module or a bluetooth module, at first, electronic control of each node device needs to be redesigned, an interface is added to meet the requirement, the cost is high, the practicability is low, and compared with program upgrade performed by using a WIFI module or a bluetooth module, the multi-split computer program upgrade method provided by this embodiment is more economical and practical.
