and S4, monitoring the operation state of the dual-mode communication module in real time, and reporting node events corresponding to the operation state of the dual-mode communication module.
The working principle of the technical scheme is as follows: s1, calling communication parameter information of a dual-mode communication module:
first, the system invokes the communication parameter information of the dual mode communication module. These parameters may include the system settings of the dual mode communication module, the frequency range, the communication rate, etc. communication related settings. By retrieving this information, the system can learn about the current configuration of the communication module.
S2, acquiring single-phase intelligent ammeter data in a telecommunication system acquisition system in real time:
the system then acquires the single-phase smart meter data in the telecommunications system acquisition system in real time. Single-phase smart meters typically have data acquisition and storage capabilities that enable measurement of power consumption and transmission of data to a telecommunications system acquisition system.
S3, carrying out self-adaptive adjustment on the communication rate according to a meter address command of the single-phase intelligent ammeter:
in this step, the system adaptively adjusts the communication rate of the dual mode communication module according to the table address command received from the single phase smart meter. The adaptive adjustment of the communication rate is to ensure that stable and efficient data transmission can be achieved in different communication environments. Depending on the location and communication quality of the single-phase smart meter, the system may dynamically adjust the communication rate to ensure reliable transmission of data.
And sending the data information of the single-phase intelligent ammeter to a user side through the self-adaptive adjusted communication rate:
after the communication rate is adaptively adjusted, the dual-mode communication module sends the data information of the single-phase intelligent ammeter to the user side. The user terminal may be a data center, a monitoring system or other terminal equipment. Through the efficient communication rate, the system can rapidly transmit the ammeter data to the user side, and real-time data monitoring and remote management are realized.

The performance index may include information such as hardware specifications of the module, supporting conditions of a communication system, a communication rate range, a modulation mode, a transmit power limit, and a receiving sensitivity. These performance metrics are key descriptions of the functionality and performance of the dual mode communication module.
S102, scanning the performance index data information to acquire communication parameter information:
in this step, the system scans and parses the performance index data information extracted from the dual-mode communication module to obtain specific communication parameter information. The communication parameter information is a configuration parameter of the dual-mode communication module in a specific communication mode, and includes the following contents:
carrier modulation scheme: modulation schemes of communication signals, such as Frequency Modulation (FM), amplitude Modulation (AM), orthogonal Frequency Division Multiplexing (OFDM), and the like, are specified.
Carrier frequency: the carrier frequency at which the communication signal is located is specified, typically in hertz (Hz).
HRF frequency: referring to the frequency of the high frequency radio frequency signal, HRF refers to the high rate frequency (High Rate Frequency).

The technical scheme has the effects that: by extracting performance index data information of the dual-mode communication module and further analyzing communication parameter information in the performance index data information, the system can know the current configuration and capability of the communication module. Such communication parameter information is a key factor in ensuring that the dual-mode communication module is in effective communication with other devices. By dynamically acquiring the communication parameter information, the system can optimize the configuration of the communication module according to the current communication requirement and the environment condition, and ensure the stability and the reliability of communication.
The technical scheme realizes the process of automatically acquiring the communication parameter information, and improves the accuracy and efficiency of configuration. By dynamically adjusting communication parameters according to different scenes and requirements, the system can adapt to different communication environments and provide better communication services. Meanwhile, the real-time monitoring of the communication parameter information is also beneficial to timely finding out communication faults or unstable factors and timely processing and maintenance, so that the stable operation of the communication system is ensured.
In one embodiment of the present invention, the communication rate is adaptively adjusted according to the address command of the single-phase smart meter, and the data information of the single-phase smart meter is sent to the user terminal through the adaptively adjusted communication rate, including:
s301, after a carrier module of the dual-mode communication module is powered on, a command for reading a table address is sent at a first communication rate;
s302, judging whether the carrier module receives response information or not in a preset waiting time length;
s303, if no response information is received within the waiting time, switching the communication rate to be a second communication rate through an STA module of the dual-mode communication module, repeatedly reading an ammeter address, and judging whether the carrier module receives the response information or not within the preset waiting time;
s304, if no response information is received within the waiting time, switching the communication rate to be a third communication rate through an STA module of the dual-mode communication module, repeatedly reading an ammeter address, and judging whether the carrier module receives the response information or not within the preset waiting time;
s305, if no response information is received within the waiting time, switching the communication rate to be a fourth communication rate through an STA module of the dual-mode communication module, repeatedly reading an ammeter address, and judging whether the carrier module receives the response information or not within the preset waiting time;
s306, repeating the steps S303-S305 until the ammeter address is read.
The 645 message example frame is as follows:
transmission 68AA AAAA AAAA AA 68 13 00DF 16
And 68 02 00 00 00 00 00 68 93 06 35 33 33 33 33 33 9F 16.
Specifically, the first communication rate is 2400bps; the second communication rate is 9600bps; the third communication rate is 1200bps; the fourth communication rate is 4800bps.
Or alternatively
The first communication rate, the second communication rate and the third communication rate are obtained by the following formula:
wherein V is 1 、V 2 、V 3 And V 4 Representing a first communication rate, a second communication rate, a third communication rate, and a fourth communication rate, respectively; v (V) 01 、V 02 、V 03 And V 04 Respectively representing an initial first communication rate, an initial second communication rate, an initial third communication rate and an initial fourth communication rate, wherein the initial first communication rate is 2400bps; the initial second communication rate is 9600bps; the initial third communication rate is 1200bps; the initial fourth communication rate is 4800bps; deltaV represents the maximum allowable floating amplitude of the communication rate in the normal communication state; b represents the current hairThe intensity of the emitted signal; b (B) 0 Representing the lowest signal transmission intensity at which signal transmission can be completed; when B is 0 -B<0, let B 0 -b=0; lambda represents the adjustment coefficient and has a value ranging from 1.32 to 1.87, and when B 0 -B<At 0, let λ=1.63; when P represents the current signal transmitting power; p (P) max Representing the maximum theoretical signal transmit power that the device can achieve.
The first communication rate, the second communication rate, the third communication rate and the fourth communication rate which are obtained through the method can be adaptively adjusted according to the actual condition of the equipment for transmitting the current signal, the matching performance of the communication rate after the adaptive adjustment and the current communication environment can be improved to the maximum extent, and the accuracy of the change adjustment of the communication rate is further improved to the maximum extent. Meanwhile, the data communication success rate can be improved to the greatest extent through the adjustment of the communication rate, and the switching times are reduced.
The working principle of the technical scheme is as follows: s301, after a carrier module of the dual-mode communication module is powered on, a command for reading a table address is sent at a first communication rate:
before the electric meter address is read, the carrier wave module of the dual-mode communication module is powered on, and a command for reading the electric meter address is sent to the single-phase intelligent electric meter by using the first communication rate.
S302, judging whether the carrier module receives response information or not in a preset waiting time length:
after the carrier module sends the command for reading the meter address, a preset waiting time is waited for waiting for the response information of the single-phase intelligent ammeter. And in the waiting time, the carrier module judges whether the response of the ammeter is received.
S303, if no response information is received within the waiting time, switching the communication rate to the second communication rate through the STA module, repeatedly reading the ammeter address, and judging whether the carrier module receives the response information or not within the preset waiting time:
if no reply message of the ammeter is received at the first communication rate, the system switches the communication rate to the second communication rate through the STA module of the dual-mode communication module, and attempts to read the ammeter address again. Then, the system waits for a preset waiting time to judge whether the response of the ammeter is received.
S304, if no response information is received within the waiting time, switching the communication rate to be a third communication rate through the STA module, repeatedly reading the ammeter address, and judging whether the carrier module receives the response information or not within the preset waiting time:
if the response of the ammeter is not received at the second communication rate, the system switches the communication rate to the third communication rate again through the STA module, and the ammeter address is repeatedly read. Then, the system waits for a preset waiting time to judge whether the response of the ammeter is received.
S305, if no response information is received within the waiting time, switching the communication rate to be the fourth communication rate through the STA module, repeatedly reading the ammeter address, and judging whether the carrier module receives the response information or not within the preset waiting time:
if the response of the ammeter is not received at the third communication rate, the system switches the communication rate to the fourth communication rate again through the STA module, and repeatedly reads the ammeter address. Then, the system waits for a preset waiting time to judge whether the response of the ammeter is received.
S306, repeating the steps S303-S305 until the ammeter address is read:
if no reply is received from the meter at the fourth communication rate, the system continues to repeat steps S303-S305 until the meter address is successfully read.
The technical scheme has the effects that: the technical scheme for adaptively adjusting the communication rate aims to solve the problem of reading the ammeter address in different communication environments. By judging whether the carrier module receives the response information or not within the preset waiting time, the system can dynamically adjust the communication rate according to the actual situation, so that the communication quality is optimized, and the probability of successfully reading the ammeter address is improved.
According to the technical scheme, the success rate of reading the ammeter address is increased, particularly when the communication environment is unstable or the ammeter distance is far, the communication rate is adjusted in a self-adaptive mode for multiple times, the system can adapt to the current communication environment gradually, the most suitable communication rate is selected, and therefore the efficiency and the reliability of reading the ammeter address are improved. Meanwhile, the manual intervention and maintenance cost are reduced by monitoring the communication state in real time and automatically adjusting the communication rate.
In one embodiment of the present invention, monitoring the operation state of the dual-mode communication module in real time, reporting the node event corresponding to the operation state of the dual-mode communication module includes:
s401, when the EVENTOUT pin of the intelligent electric meter is at a high level, the dual-mode communication module considers that an event occurs after detecting the event. If the intelligent ammeter is 645 meters, the dual-mode communication module actively collects ammeter events and reports the ammeter events to the master node; if the intelligent ammeter is 698, reporting the frame of the self-organizing 645 frame of the dual-mode communication module to the master node;
s402, when the dual-mode communication module detects that the ammeter has a power failure, reporting a power failure event to the main node module;
s403, the dual-mode communication module supports a remote upgrading function, updates programs of part or all carrier modules of the area at regular time, and reports updated information.
The working principle of the technical scheme is as follows: s401, when the EVENTOUT pin of the intelligent electric meter is high, the dual-mode communication module considers that an event occurs after detecting:
when an EVENTOUT pin of the intelligent ammeter is in a high level state, the dual-mode communication module senses the change and judges that an event occurs; the eventut pin is typically used to indicate that a specific event has occurred inside the smart meter, such as the power usage exceeding a threshold, meter failure, etc.
If the smart meter belongs to 645 meters, the dual-mode communication module actively collects event information of the meter and reports the event information to the master node module. Thus, the main node module can know the event of the intelligent ammeter in real time, so as to respond or process correspondingly.
If the smart meter belongs to 698 tables, the dual-mode communication module frames the ad hoc 645 and reports to the master node module. This is because 645 and 698 are two different communication protocols, the dual-mode communication module may need to convert the 698 protocol events to 645 protocol format for reporting.
S402, when the dual-mode communication module detects that the ammeter has a power failure, reporting a power failure event to the main node module:
when the dual-mode communication module detects that the intelligent ammeter has power failure, the dual-mode communication module senses the state change and reports a power failure event to the main node module. Thus, the master node module can timely know the power failure condition of the ammeter so as to take corresponding measures or inform related personnel.
S403, the dual-mode communication module supports a remote upgrading function, updates programs of part or all carrier modules of the platform area at regular time, and reports updated information:
the dual-mode communication module supports a remote upgrade function, meaning that the master node module can perform program update on the carrier module of the dual-mode communication module through a remote instruction. These carrier modules may be located on some or all of the smart meters of the area under which the power supply is located. After the main node module sends out the update instruction, the dual-mode communication module executes program update at regular time and reports the update information to the main node module so as to feed back the updated state and result.
