The present embodiment provides a program upgrading method, which is applied to a data transmission terminal DTU of a multi-device linkage system, where the multi-device linkage system refers to a system having at least one DTU and at least two power devices, for example, a monitoring system including multiple cameras or an air conditioning system including multiple external units, where the power devices can perform linkage operation and output a certain load power, and an external unit in the air conditioning system is a typical power device, and the present embodiment takes the air conditioning system including multiple external units as an example to describe in detail the program upgrading method of the present invention, where the program upgrading method is applied to a data transmission terminal DTU of an existing air conditioning system, fig. 2 is a flowchart of the program upgrading method according to a first embodiment of the present invention, and as shown in fig. 2, the method includes:
s201, determining the outdoor unit to be upgraded, and sending a program upgrading package to the outdoor unit to be upgraded.
The DTU prestores the MAC code of each outdoor unit, which corresponds to the outdoor unit one to one, that is, each outdoor unit has a unique MAC code, so as to distinguish different outdoor units. And determining the outdoor unit to be upgraded according to the program reported by each outdoor unit and the unique MAC code of each outdoor unit.
S202, determining whether to send an upgrading instruction to the power equipment to be upgraded according to the running state of the power equipment to be upgraded.
When determining whether to upgrade, the operating state of the external unit needs to be considered, wherein the operating state includes a working state and a non-working state, and the external unit is stopped in the program upgrading process, so that if the program upgrading is performed when the external unit is in the working state, the operation of the external unit is interrupted unexpectedly, and in order to avoid the problem, the operating state of the external unit to be upgraded needs to be determined in advance, and whether to perform the program upgrading immediately is determined according to the operating state of the external unit.
In the program upgrading method of the embodiment, the program versions reported by all external units in the air conditioning system are received; determining an external machine to be upgraded according to the program version, and sending a program upgrading package to the external machine to be upgraded; whether an upgrading instruction is sent to the outdoor unit to be upgraded is determined according to the running state of the outdoor unit to be upgraded, the situation that the system cannot run normally due to the fact that the outdoor units in work are upgraded simultaneously can be avoided, program upgrading of all the outdoor units is achieved gradually, and meanwhile the load power requirement and the program upgrading requirement are met.
Example 2
The embodiment provides another program upgrading method for determining an external unit to be upgraded, including: receiving program versions reported by each power device in the multi-device linkage system; and determining the power equipment to be upgraded according to the program version. And the external unit reports the program version of the control program executed by the external unit to the DTU in real time or at preset intervals, so that the DTU can conveniently judge whether the control program of the external unit is the latest version and needs to be updated.
Specifically, while receiving the program version of each external unit in the air conditioning unit, the DTU also obtains the program of the latest version from the server, and determines whether the program version of each external unit is the latest version, that is, determines whether the external unit needs to be upgraded according to the program version, which specifically includes: acquiring a program upgrading package from a server; wherein, the program in the program upgrading package is the latest version; comparing the program version reported by each outdoor unit with the latest version one by one, and determining whether the program version reported by each outdoor unit is the latest version; and determining the out unit of which the program version is not the latest version as the out unit to be upgraded.
In the embodiment, when the external units to be upgraded are determined, each external unit comprises an original external unit and a rejoined external unit in the air conditioning system; the DTU controls an original external unit of the air-conditioning system to upgrade, and simultaneously monitors whether a rejoined external unit exists in the air-conditioning system, if the rejoined external unit exists, wherein the original external unit is the external unit which is connected with the DTU before the air-conditioning system is upgraded, the rejoined external unit is the external unit which is newly connected with the DTU after the air-conditioning system is upgraded, whether the rejoined power equipment is the power equipment to be upgraded is determined according to the program version of the rejoined power equipment, and then the program upgrading method which is the same as the embodiment is executed.
The program upgrading process can lead to outer machine to shut down, in order not to influence system operation, outer machine after receiving the program upgrade package, can not upgrade immediately, but sends inquiry message earlier, and DTU receives this inquiry message after, confirms whether to send the upgrading instruction to it according to the running state of waiting to upgrade outer machine, specifically includes: acquiring the running state of an external unit to be upgraded; if the external machine to be upgraded is in a non-working state, the external machine to be upgraded can be upgraded immediately, and an upgrading instruction is sent to the external machine to be upgraded at the moment; and if the external unit to be upgraded is in a working state, the external unit to be upgraded cannot be upgraded immediately, the external unit to be upgraded needs to be added into a task list, the running state of the external unit to be upgraded is monitored, and an upgrading instruction is sent to the external unit to be upgraded after the external unit to be upgraded enters a non-working state.
Because the air conditioning system comprises a plurality of outdoor units, some outdoor units may finish program upgrading firstly and are in a non-working state, the outdoor units to be upgraded can be temporarily replaced by the outdoor units to work, so that the outdoor units to be upgraded are upgraded in time, and the program upgrading efficiency of the whole multi-equipment linkage system is improved, therefore, before the outdoor units to be upgraded are added into a task list, the method can also comprise the following steps of:
judging whether a target outdoor unit exists in the air conditioning system; the target outdoor unit is an outdoor unit which is upgraded and is in a non-working state; if the external unit to be upgraded can be replaced in the air-conditioning system, the target external unit is controlled to replace the external unit to be upgraded to work, and an upgrading instruction is sent to the external unit to be upgraded, so that the external unit to be upgraded is upgraded in time; if not, the fact that the air conditioner system does not have an external unit capable of replacing the external unit to be upgraded to work is indicated, the external unit to be upgraded is triggered to be added into the task list, and the external unit to be upgraded is waited for at a proper time to be upgraded.
After the external unit to be upgraded is added into the task list, on one hand, the external unit to be upgraded can wait for the external unit to be upgraded to enter a non-working state, and then the external unit to be upgraded is controlled to be upgraded, and on the other hand, whether a new external unit capable of replacing the external unit to be upgraded to work appears in the air conditioning system can also be detected, so that after the external unit to be upgraded is added into the task list, the method can further comprise the following steps: judging whether a target outdoor unit exists in the air conditioning system; if so, controlling the target external unit to replace the external unit to be upgraded in the task list to work, and sending an upgrading instruction to the external unit to be upgraded; and if not, continuously monitoring whether a target external unit exists in the air-conditioning system or not until the target external unit appears in the air-conditioning system, and triggering and controlling the target external unit to replace the external unit to be upgraded in the task list to work.
The air conditioning system comprises a plurality of outdoor units, the use frequency of each outdoor unit is possibly different, if the use frequency of the outdoor unit is low, the program upgrading is delayed a little, and no great influence is caused, but for the outdoor unit with higher use frequency, the program upgrading is delayed to cause great influence on the operation of the whole air conditioning system, and based on the consideration, after the outdoor unit to be upgraded is added into the task list, the method further comprises the following steps: when the number of the external units to be upgraded in the task list is two or more, acquiring the historical use frequency of each external unit to be upgraded; determining the upgrading sequence of the outdoor unit to be upgraded according to the historical use frequency; wherein, the higher the historical use frequency is, the more advanced the upgrading sequence is. For example, the outdoor unit to be upgraded with the highest use frequency is arranged in the first order, the outdoor unit to be upgraded with the next highest use frequency is arranged in the second order, and so on, if the use frequencies of the two outdoor units to be upgraded are the same, the front-back order can be determined by pre-storing the MAC code of each outdoor unit, for example, the last outdoor unit with the smaller bit of the MAC code is arranged in front, or the last larger bit of the MAC code is arranged in front.
And after the target external unit appears, replacing the external unit to be upgraded in the task list according to the upgrading sequence in the task list. And each external unit in the task list is cleared from the task list after the upgrading is finished, so that the external unit to be upgraded which is originally positioned in the first order is cleared from the list after the upgrading is finished, the external unit to be upgraded which is originally positioned in the second order moves forwards to become the first order external unit to be upgraded, and when the target external unit appears in the air conditioning system again, the external unit to be upgraded is preferentially replaced, and then the program upgrading is preferentially carried out. If two target external units appear in the air conditioning system at the same time, two external units to be upgraded in the first order and the second order in the task list can be replaced at the same time, if three target external units appear at the same time, the first three external units to be upgraded in the task list can be replaced, and the like.
Because the external machine needs a certain time to receive the program upgrade package, when the program upgrade package is not received, the running state of the external machine may be in a non-working state, but may also be changed into a working state after the program upgrade package is received, and thus, after the program upgrade package is received by the external machine, the external machine reports the running state to the DTU and sends an inquiry message, and the DTU monitors whether the inquiry message sent by the power equipment to be upgraded is received in real time; and after receiving the inquiry message, triggering to determine whether to send an upgrade instruction to the power equipment to be upgraded according to the running state of the power equipment to be upgraded, wherein the inquiry message is used for representing the receiving completion of the program upgrade package and confirming whether to upgrade.
Example 3
The present embodiment provides a program upgrading method applied to an external unit (i.e., a power device in a multi-device linkage system) of an air conditioning system, and fig. 3 is a flowchart of the program upgrading method according to a third embodiment of the present invention, as shown in fig. 3, the method includes:
s301, reporting the program version to the DTU. The reporting of the program version to the data transmission terminal DTU can be carried out in real time, and the reporting can also be carried out at intervals of preset time in order to avoid reduction of transmission speed caused by over-intensive data transmission.
S302, receiving a program upgrade package sent by the DTU; and the program upgrade package is sent to the external machine by the DTU after determining that the program version is not the latest version.
S303, reporting the running state to the DTU and sending an inquiry message to confirm whether to upgrade. In order to not affect the system operation, the external unit does not immediately upgrade after receiving the program upgrade package, but sends an inquiry message to the DTU to confirm whether to upgrade.
And S304, after receiving the upgrading instruction sent by the DTU, upgrading the program.
According to the program upgrading method, the external unit does not upgrade immediately after receiving the program upgrading packet, but sends an inquiry message to the DTU to confirm whether upgrading is performed or not, and program upgrading is performed after an upgrading instruction sent by the DTU is received, so that the situation that the external unit in a working state is upgraded to cause the sudden stop of operation of the external unit and influence on load power output of the whole system can be avoided.
Example 4
In order to enable the DTU to determine whether to upgrade the external unit to be upgraded according to the operating state, the method further includes, while sending an inquiry message to the DTU, the step of: and reporting the running state. And the DTU sends an upgrading instruction to the external unit to be upgraded when confirming that the running state of the external unit to be upgraded is a non-working state.
Example 5
The embodiment provides a program upgrading method which is applied to an air conditioning system. As shown in fig. 1 mentioned above, the air conditioning system includes a plurality of external units, the plurality of external units are scheduled and managed by the DTU, and during the upgrade process, the DTU obtains the latest version of the control program from the remote server, stores the data packet locally, and implements local upgrade management of the air conditioning system.

And S2, the DTU acquires the program version of the external unit from the heartbeat data reported by the external unit. During the process of using the program of the multi-outdoor unit air conditioning system, the DTU needs to monitor the program version of each outdoor unit in the air conditioning unit.
And S3, the DTU judges whether the program version of each outdoor unit is the latest version according to the latest version in the program upgrading packet acquired from the server, and determines the outdoor unit of which the program version is not the latest version as the outdoor unit to be upgraded. While monitoring the program version of each outdoor unit in the air conditioning unit, the DTU needs to acquire the program of the latest version from the server. And when the program version of a certain outdoor unit is not the latest version, determining the outdoor unit as the outdoor unit to be upgraded.
And S4, the DTU sends a program upgrading packet to the external unit to be upgraded.
And S5, the external unit to be upgraded receives the program upgrade package, and sends an inquiry message for confirming whether to upgrade to the DTU after the reception is finished. Because the external unit is shut down in the upgrading process, in order to not affect the operation of the system, the external unit does not immediately enter upgrading after the program upgrading package is downloaded, an inquiry message for confirming whether upgrading is performed needs to be sent to the DTU, and upgrading can be performed after an upgrading instruction sent by the DTU is received.
And S6, the DTU receives the inquiry message and acquires the running state of the external unit to be upgraded from the heartbeat data of the external unit to be upgraded.
And S7, the DTU judges whether the external unit to be upgraded is in an idle state according to the running state external unit, if so, the step S8 is executed, and if not, the step S9 is executed.
And S8, the DTU sends an upgrading instruction to the external unit to be upgraded.
S9, the DTU judges whether an external machine which is in an idle state and finishes upgrading exists; if so, go to step S10; if not, step S11 is performed.
And S10, the DTU controls the outdoor unit which is in an idle state and finishes upgrading to start, replaces the outdoor unit to be upgraded to work, and simultaneously sends an upgrading instruction to the replaced outdoor unit to be upgraded.
And S11, the DTU adds the external unit to be upgraded into the task list.
The DTU judges whether the external unit to be upgraded is in an idle state, if the external unit to be upgraded is in the idle state, the external unit to be upgraded can be directly controlled to be upgraded, and an upgrading instruction is directly sent at the moment; and if the external unit to be upgraded is in a working state, judging whether other idle and upgraded external units exist in the air-conditioning system, if so, dispatching the external unit to start replacing the external unit to be upgraded by sending a control instruction to work, and if not, adding the external unit to be upgraded into a task list.
And S12, the DTU monitors the running state of the external unit to be upgraded in the task list, the running states of other external units outside the task list and the upgrading completion conditions of other external units outside the task list.
S13, the DTU judges whether the external unit to be upgraded is idle according to the running state of the external unit to be upgraded; if so, step S14 is performed, and if not, step S15 is performed.
And S14, the DTU sends an upgrading instruction to the external unit to be upgraded.
S15, the DTU judges whether an external machine which is in an idle state and finishes upgrading exists; if yes, go to step S16; if not, return is made to step S12.
And S16, the DTU controls the outdoor unit which is in an idle state and finishes upgrading to start, replaces any outdoor unit to be upgraded in the task list to work, and simultaneously sends an upgrading instruction to the replaced outdoor unit to be upgraded.
