For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made with reference to the accompanying drawings of the present invention by way of specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a communication method of a dual-mode module electric energy meter in a power grid. The dual-mode module electric energy meter is provided with a plurality of transmission channels between the dual-mode module and the control master station. The communication method comprises steps S101-S104.
S101, monitoring transmission states of the plurality of transmission channels.
In some embodiments, the transmission states of the transmission channel include a normal state and an abnormal state. The normal state indicates that the message transmission delay is smaller, and data can be normally transmitted. The abnormal state indicates that the message transmission delay is larger, and the data transmission process is congested.
In some embodiments, the dual mode module of the power meter may include any two of the following communication modules: carrier module, wireless module, micropower module and bluetooth module.
By way of example, the dual mode module of the power meter may include a carrier module and a wireless module; alternatively, the dual-mode module of the electric energy meter may include a carrier module and a micropower module; alternatively, the dual mode module of the power meter may include a wireless module and a bluetooth module.
In some embodiments, the control master station is provided with various types of communication modules, such as carrier modules, wireless modules, micro-power modules, and bluetooth modules.
By way of example, the control master station may comprise four communication modules. Such as carrier modules, wireless modules, micro-power modules, and bluetooth modules. Alternatively, the control master station may comprise one carrier module, two radio modules, three micropower modules and two bluetooth modules. Alternatively, the control master station may comprise a carrier module and a radio module.
In some embodiments, the dual-mode module electric energy meter is provided with a plurality of transmission channels between the dual-mode module and the control master station.
For example, two transmission channels may be provided between the dual-mode module power meter and the control master station. If the dual-mode module electric energy meter is provided with a first transmission channel between the carrier module and the control master station. The dual-mode module electric energy meter is provided with a second transmission channel between the wireless module and the control master station.
In yet another example, multiple transmission channels may be provided between the dual-mode module power meter and the control master station. If the dual-mode module electric energy meter is provided with a first transmission channel between the carrier module and a first carrier module of the control master station. The dual-mode module electric energy meter is provided with a second transmission channel between the carrier module and a second carrier module of the control master station. The dual-mode module electric energy meter is provided with a third transmission channel between the wireless module and the first wireless module of the control master station. The electric energy meter with the dual-mode module is provided with a fourth transmission channel between the wireless module and a second wireless module of the control master station.
In some embodiments, the dual-mode module power meter may be connected to a concentrator, which is connected to a control master station. Thus, the dual-mode module electric energy meter establishes a transmission channel through the concentrator and the control master station.
For example, the concentrator may be provided with two or more communication modules. Such as a concentrator is provided with a carrier module and a radio module. The carrier module of the electric energy meter and the carrier module of the concentrator are communicated with each other to form a transmission channel for data transmission. The wireless module of the electric energy meter and the wireless module of the concentrator are communicated with each other to form a transmission channel for data transmission.
As a possible implementation manner, the embodiment of the present invention may determine the transmission status of each of the plurality of transmission channels one by one.
For example, for any transmission channel, embodiments of the present invention may determine the status of the transmission channel through steps S1011-S1015.
S1011, determining the sending time of a first negotiation message to the control master station and the receiving time of a second negotiation message returned by the control master station for each transmission channel of the plurality of transmission channels.
The embodiment of the invention can send the first negotiation message to the control master station, record the sending time of the first negotiation message, receive the second negotiation message returned by the control master station, and record the receiving time of the second negotiation message.
The embodiment of the invention can receive the second negotiation message within a set time period after sending the first negotiation message. If the second negotiation message is received within the set time length, recording the receiving time of the second negotiation message. If the second negotiation message is not received within the set time length, recording the time corresponding to the set time length after the first negotiation message is sent as the receiving time of the second negotiation message.
Illustratively, the electric energy meter may communicate directly with the control master station, send a first negotiation message, and receive a second negotiation message.
In another example, the electric energy meter may also send the first negotiation message to the concentrator first. The concentrator collects the first negotiation messages of the plurality of electric energy meters and then uniformly transmits the first negotiation messages to the control master station.
For example, in the embodiment of the invention, the first negotiation message can be sent to the carrier module of the concentrator through the carrier module of the electric energy meter, and the sending time of the first negotiation message is recorded; and receiving a second negotiation message sent by the carrier module of the concentrator through the carrier module of the electric energy meter, and recording the receiving time of the second negotiation message.
S1012, calculating the message transmission delay of each transmission channel according to the receiving time of the second negotiation message and the sending time of the first negotiation message.
For example, assuming that the sending time of the first negotiation message is T1 and the receiving time of the second negotiation message is T2, the message transmission delay is t3=t2-T1.
S1013, determining that the transmission state of the transmission channel with the message transmission delay smaller than or equal to a preset threshold value is a normal state, and determining that the transmission state of the transmission channel with the message transmission delay larger than the preset threshold value is an abnormal state.
If the message transmission delay is smaller than or equal to a preset threshold value, determining that the transmission channel is in a normal state. The message transmission delay is smaller than or equal to a preset threshold value, which indicates that the transmission state of the transmission channel is good, and the transmission channel is in a normal state. The preset threshold may be 100ms, or may be determined according to an actual transmission situation.
If the message transmission delay is greater than the preset threshold, determining that the transmission channel is in an abnormal state. The message transmission delay is larger than a preset threshold value, which indicates that the transmission state of the transmission channel is poor, and even the second negotiation message is not received, the transmission channel is in an abnormal state.
Thus, the embodiment of the invention can calculate the message transmission delay of each transmission channel between the electric energy meter and the control master station through mutual message transmission, determine the transmission state of each transmission channel, and quantize the transmission state of each transmission channel in time through the message transmission delay so as to improve the refinement degree of the transmission state.
S102, if the transmission state of the current transmission channel communicated with the control master station is abnormal, determining the transmission channel with the transmission state being normal among the rest transmission channels except the current transmission channel.
S103, acquiring the transmission time delay of the transmission channel in the normal state, and selecting a main selection decision channel from the transmission channels in the normal state based on the transmission time delay.
As a possible implementation manner, the embodiment of the present invention may determine the main selection decision channel through steps S1021-S1025.
S1021, if the transmission state of the current transmission channel is abnormal, judging whether the transmission channels in the normal state exist in other transmission channels except the current transmission channel.
And S1022, if the transmission channel in the normal state exists, acquiring the transmission delay of the transmission channel in the normal state.
S1023, selecting a main selection decision channel from the transmission channels in the normal state based on the transmission delay.
The embodiment of the invention can determine the transmission channel with the minimum transmission delay from the transmission channels in the normal state based on the transmission delay; and determining the transmission channel with the minimum transmission delay as the main selection decision channel.
S1024, if no transmission channel in the normal state exists, the transmission delay of each remaining transmission channel is obtained.
S1025, if the transmission delay of the first channel is smaller than the transmission delay of the current transmission channel, determining the first channel as the main selection decision channel.
The first channel is any one of the remaining transmission channels.
Therefore, when the current transmission channel is abnormal, the embodiment of the invention can be switched to a normal transmission channel or a transmission channel with smaller transmission delay, thereby ensuring the data transmission rate between the electric energy meter and the control master station and improving the communication efficiency.
S104, data transmission is carried out through the main selection decision channel.
The embodiment of the invention can record the metering data of the electric energy meter in the current unit time period; and transmitting metering data in the current unit time period to the control master station by adopting a main selection decision channel.
The invention provides a communication method of a dual-mode module electric energy meter in a power grid, which is characterized in that the transmission states of all transmission channels between the electric energy meter and a control master station are detected, the transmission channel in a normal state is determined when the transmission state of the current transmission channel is an abnormal state, a main selection decision channel is selected based on the transmission time delay of the transmission channel in the normal state, and data transmission is carried out through the main selection decision channel, so that the problem of uneven distribution among the transmission channels in the dual-mode communication process is solved, and the data transmission rate and the communication efficiency between the electric energy meter and the control master station are improved.
Optionally, as shown in fig. 2, the communication method of the dual-mode module electric energy meter in the power grid provided by the embodiment of the invention further includes steps S201 to S204.
S201, if the transmission state of the current transmission channel is a normal state, periodically comparing the transmission time delay of the transmission channel with the transmission state of the normal state in the plurality of transmission channels.
S202, if the transmission delay of the second channel is smaller than that of the current transmission channel, determining that the transmission state of the second channel is better than that of the current transmission channel.
In some embodiments, the second channel is any one of the plurality of transmission channels except the current transmission channel, and the transmission state is a normal state.
S203, recording the continuous times of the transmission state of the second channel superior to the transmission state of the current transmission channel.
S204, if the continuous times are greater than or equal to the set times, determining the second channel as a main selection decision channel, and transmitting data through the main selection decision channel.
Therefore, when the current transmission channel is normal, the embodiment of the invention can periodically detect the transmission time delay of each transmission channel, switch to the transmission channel with smaller transmission time delay for data transmission, and improve the data transmission rate and the communication efficiency between the electric energy meter and the control master station.
For example, when the current transmission channel is normal, the electric energy meter and the control master station meter normally and periodically detect the transmission delay of the message, if the transmission delay of 10 continuous messages exceeds the specified time, and the smoothness detection of another channel is better, the other channel is switched to read the power consumption data, and the transmission delay time of the corresponding channel is also calculated; if the delay time of the channel is equal to that of the original channel or less than that of the previous channel, keeping the channel to send data; if the channel transmission delay is longer than the prescribed time, the channel is switched again for transmission.
Optionally, as shown in fig. 3, the communication method of the dual-mode module electric energy meter in the power grid provided by the embodiment of the invention further includes steps S301 to S303.
S301, receiving a switching instruction sent by a control master station.
In some embodiments, the switching instruction is configured to instruct the electric energy meter to switch the main selection decision channel to the third channel.
Illustratively, the third channel is any one of a plurality of transmission channels.
S302, if the current transmission channel is the third channel, keeping the current transmission channel as the main selection decision channel unchanged.
S303, if the current transmission channel is other channels than the third channel, determining the third channel as a main selection decision channel, and transmitting data through the main selection decision channel.
It should be noted that, the electric energy meter may switch transmission channels based on the indication of the control master station, so as to implement the planning decision of the transmission channels. For example, when a certain transmission channel of the control master station is in period 22: when 00-24:00 is used for overhauling, the occupied resources are high, and the control master station can send a switching instruction to the electric energy meter in advance to instruct the electric energy meter to be switched to another transmission channel. For example, when the wireless public network is used for maintenance, the electric energy meter can be instructed to switch to the carrier channel, i.e. the third channel is the carrier channel.
Optionally, as shown in fig. 4, the communication method of the dual-mode module electric energy meter in the power grid provided by the embodiment of the invention further includes steps S401 to S402.
S401, acquiring a time period where the current moment is located.
S402, if the period of the current moment is a busy hour period, determining a fourth channel as a main selection decision channel; and data transmission is carried out through the main selection decision channel.
And the fourth channel is a transmission channel which is communicated with the control master station in a busy time period.
It should be noted that, in the busy hour period, a load of a certain transmission channel is heavy, and the electric energy meter can avoid the busy hour period in advance, and adopts another transmission channel to transmit data.
