In an alternative embodiment, the method for receiving the external control signal and generating the first valve control command according to the external control signal includes: a first valve control command is generated based on an external control signal received from a single device. If the management platform sends an external control signal for opening the valve to the valve terminal, the valve terminal processes the external control signal into a first valve control instruction which can be executed by the valve.
In an alternative embodiment, the method for receiving the external control signal and generating the first valve control command according to the external control signal includes: and generating a first valve control instruction according to the external control signals jointly input by the plurality of devices.

and when the first control signal and/or the confirmation information of the first control signal sent by all the devices on the device list are received within a first threshold time after the first control signal is received, generating a first valve control instruction according to the first control signal.

S2, acquiring a second valve control instruction which is being executed;
in the implementation process, the method for acquiring the second valve control instruction may be acquired from a memory connected to the valve terminal, or may be acquired through communication with an external device.
In an alternative implementation manner, when the acquisition method is that the valve terminal sends a query instruction to the management platform during communication acquisition with the external device, the management platform queries all control instructions and/or latest executed control instructions pointing to the device ID in the database through the device ID of the valve terminal, and determines a second valve control instruction being executed by the valve terminal according to the query result. By adopting the scheme, a memory is not required to be arranged on the valve terminal, so that the cost is saved.
In an alternative embodiment, each time the management platform issues a valve control instruction, the valve control instruction is stored in the database, specifically, the valve control instruction is stored in a row or column in the data table where the device ID corresponding to the valve control instruction is located.
In an alternative embodiment, the query method queries all valve control instructions pointing to the device ID, processes all queried valve control instructions, screens out a second valve control instruction being executed by the valve terminal, and the screening method is as follows: all valve control instructions are sequenced from new to old, whether the priority of the valve control instruction with the sequence number of n is higher than that of the valve control instruction with the sequence number of n+1 is judged from n=1, if so, the valve control instruction with the sequence number of n is a second valve control instruction which is being executed by the valve terminal, if not, n=n+1 is set, and then the judgment is executed.

On the basis, the inquiring method can be to inquire the latest executed control instruction of the equipment ID of the valve terminal by screening the marked data, wherein the inquired latest executed control instruction is the second valve control instruction which is being executed by the valve terminal.
In an alternative embodiment, the valve terminal, when receiving the valve control instruction sent by the other device, uploads the received valve control instruction to the management platform. Because the valve terminal is possibly controlled by other devices in the Internet of things besides the control of the management platform, the second valve control instruction in the database of the management platform can be updated in real time by adopting the scheme.
In the specific implementation process, the external control signal and the valve control instruction can be mutually converted, the valve control instruction can be obtained by processing the external control signal, and the external control signal can be obtained by processing the valve control instruction.
S3, judging the priority of the first valve control instruction and the second valve control instruction based on the first valve control instruction and the second valve control instruction;
in the specific implementation process, the priorities of the first valve control instruction and the second valve control instruction are different due to different objects, different operations, different reasons for emission and the like, so that the valve terminal can calculate and judge the priorities of the first valve control instruction and the second valve control instruction according to the different priorities in order to avoid misoperation of the valve terminal.
In an alternative embodiment, the first valve control instruction and/or the second valve control instruction comprises a valve control parameter and at least one data tag;

In an alternative embodiment, the data tag may be directly input or selected from the outside, or may be generated by the valve terminal or other device in communication with the valve terminal according to a preset rule. For example, the data tag "user" may be selected directly by the user when the first valve control command is entered by the user, and the valve terminal or user terminal may automatically add the data tag "user" to the first valve control command when the first valve control command is entered by the user terminal.
In an alternative embodiment, the step of determining the priority of the first valve control command and the second valve control command includes:
reading a first data tag in a first valve control instruction and a second data tag in a second valve control instruction;

and determining the priorities of the first valve control instruction and the second valve control instruction according to the priorities of the first data tag and the second data tag.
In an alternative implementation, the data tag may be priority data directly, for example, the content of the first data tag may be "priority 3", and the content of the second data tag may be "priority 2", where, according to a preset rule, if the priority number is larger, the priority of the first valve control instruction is higher than that of the second valve control instruction, and if the priority number is smaller, the priority of the first valve control instruction is higher than that of the second valve control instruction.
In an alternative embodiment, the data tag may be an open/close tag of the valve directly, e.g. the content of the first data tag may be "close valve" and the content of the second data tag may be "open valve", the priority of "close valve" being higher than "open valve", i.e. the priority of the first valve control command is higher than the priority of the second valve control command, from a security point of view.
In an alternative embodiment, the data tag may be directly the source device tag of the valve control instruction, e.g. the content of the first data tag may be a "management platform" and the content of the second data tag may be a "user", the priority of the "management platform" being higher than the "user" from a security point of view, i.e. the priority of the first valve control instruction is higher than the second valve control instruction. Since the source device of the valve control instruction may be a plurality of devices, for example, the content of the first data tag may be "management platform+gas meter terminal", and the content of the second data tag may be "gas meter terminal", the priority of "management platform+gas meter terminal" is higher than that of "gas meter terminal", i.e., the priority of the first valve control instruction is higher than that of the second valve control instruction, from the viewpoint of safety.
In an alternative embodiment, the data tag may be some simple combination tag, for example, the content of the first data tag may be "user closed valve", i.e. a control command sent by the user to close the valve, and the content of the second data tag may be "system open valve", i.e. a command sent by the system to open the valve, where the priority cannot be evaluated using a linear relationship from the perspective of security and user experience, and only a plurality of logics may be used to make the determination, including: the priority of the "system closed valve" is higher than the priority of the "user open valve", the priority of the "system open valve" is equal to the priority of the "system closed valve", the priority of the "user open valve" is equal to the priority of the "user closed valve", the priority of the "user closed valve" is higher than the priority of the "system open valve", and the like, and the direct priority relationships of the two labels are independent, so that the priority of the first valve control instruction is still higher than the second valve control instruction.
In an alternative embodiment, the valve control instruction may also include a plurality of data tags, and when the valve control instruction includes the plurality of data tags, the first data tag group in the first valve control instruction and the second data tag group in the second valve control instruction are read;
determining priorities of the first data tag group and the second data tag group based on a data tag prioritization algorithm and/or a prioritization index system according to the first data tag group and the second data tag group; specifically, the weights can be preset for the tags in the first data tag group and the second data tag group, and the tags can be judged from high to low according to the weights, or can be judged after priority calculation according to a weighting algorithm.

S4, if the priority of the first valve control instruction is not lower than that of the second valve control instruction, performing valve control according to the first valve control instruction;
in the implementation process, if the priority of the first valve control instruction is not lower than that of the second valve control instruction, the first valve control instruction may be a code used for valve control by the valve terminal, or may be a parameter, text or code used for valve control after being processed by the valve terminal.
In an alternative embodiment, the first valve control instruction further includes a data tag, where the data tag does not affect the control of the valve by the valve terminal.
In an alternative embodiment, after the step of determining the priorities of the first valve control instruction and the second valve control instruction based on the first valve control instruction and the second valve control instruction, the method further includes:
s5, if the priority of the first valve control instruction is lower than that of the second valve control instruction, generating feedback information of a data tag with the second valve control instruction;
and S501, sending feedback information to a source device of the first valve control instruction and/or a user terminal matched with the valve terminal.

By adopting the method, the source equipment of the first valve control instruction can clearly acquire the execution condition of the first valve control instruction, and meanwhile, whether the valve control instruction with higher priority needs to be sent or not is judged as the first valve control instruction according to the feedback information.
The optional method of receiving an external control signal comprises at least one of receiving through a network and receiving through near field communication.
