Abstract
The invention discloses a method for preventing wireless radio frequency communication interference. The method is mainly used in an electric system for sending of fault messages and is used for solving the problem of interference of data transmission of traditional wireless radio frequency communication. The method comprises the steps of 1) monitoring fault messages; 2) detecting message field intensity; 3) sending messages; 4) replying messages; and 5) confirming answers. By the aid of the method, the data transmission interference of wireless radio frequency communication can be avoided effectively, the power consumption of an indicator can be effectively reduced, the effective transmission of data can be guaranteed, the power supply reliability, the automation degree and the informatization level can be improved, and powerful guarantees can be provided for normal operation of circuits.
Description
Technical field
The present invention relates to wireless communication technology field, specifically a kind of method of avoiding the twireless radio-frequency communication conflict.
Background technology
Development along with radio-frequency technique, integrated circuit technique, the realization of radio communication function is more and more easier, and data transmission bauds is also more and more faster, and reaches gradually the level that can compare favourably with cable network, therefore, the twireless radio-frequency communication technology also is applied to power domain gradually.At present, be in terminal and fault detector equipment, wireless radio frequency modules to be installed mostly, finish the short-distance transmission of data.But, in the process of communication, when a plurality of fault detectors send fault message simultaneously, because conflict causes information seriously to be lost.
Clash for avoiding twireless radio-frequency communication to transmit between the fault message at fault detector, can adopt in the communication multiplexing mechanism commonly used, and shake hands and the triple mechanism of data validation mechanism are come the reliable and effective transmission of guarantee information in conjunction with field intensity testing mechanism, two-way communication.
Summary of the invention
The invention provides a kind of method of avoiding the twireless radio-frequency communication conflict, efficiently solve a plurality of fault messages and send simultaneously the problem that causes conflict to cause information dropout.
In order to address the above problem, the present invention by the following technical solutions: a kind of method of avoiding the twireless radio-frequency communication conflict, be used for electric power system to the process of transmitting of fault message, it is characterized in that, may further comprise the steps:
Fault message is monitored: fault detector is received the fault message that send the fault point, so that fault detector transfers state of activation to by resting state, and carries out the preparation of posting a letter;
The information field intensity detects: fault detector scans detection to the information field intensity in the setting range S, confirms not exist in setting range S the out of Memory field intensity;
Information sends: fault detector is sent to communication terminal by wireless radio frequency modules with fault message, the counter records number of times of posting a letter;
Information-reply: communication terminal carries out the answer of confirmation to the fault detector that sends fault message;
Write in reply and confirm: fault detector acknowledges receipt of the letter in reply of communication terminal, finishes the transmission of fault message.
Further, in described information field intensity detecting step, there is the out of Memory field intensity in the setting range if detect, the fault detector Random assignment stand-by period, and when the stand-by period finishes, again carry out the information field intensity and detect, until do not exist till the out of Memory field intensity in the setting range.
Further, described letter in reply confirms that if fault detector does not receive the letter in reply of communication terminal, fault detector is posted a letter again in the step, and fault detector still can not receive letter in reply after rolling counters forward reaches 6 times, and fault detector is connected alarm.
Further, described setting range S is take fault detector as the center of circle, and 10 meters is the border circular areas of radius.
The invention has the beneficial effects as follows: the present invention has effectively avoided the data transmission conflict problem of twireless radio-frequency communication, effectively reduce the power consumption of indicating device, guaranteed effective transmission of data, improved power supply reliability, automation and the level of IT application, for the normal operation of circuit provides powerful guarantee.
Description of drawings
Fig. 1 is schematic flow sheet of the present invention.
Embodiment
As shown in Figure 1, a kind of method of avoiding the twireless radio-frequency communication conflict of this invention is used for electric power system to the process of transmitting of fault message, and described method may further comprise the steps:
1) fault detector is received the fault message that send the fault point, so that fault detector transfers state of activation to by resting state, and carries out the preparation of posting a letter.
2) fault detector scans detection to the information field intensity that has an area of in 10 meters, if there is the out of Memory field intensity in setting range, then enters step 3), otherwise enters step 4).
3) the fault detector Random assignment stand-by period, and after the stand-by period finishes, change step 2 over to).
4) fault detector is sent to communication terminal by wireless radio frequency modules with fault message, and counter begins to record the number of times of posting a letter;
5) communication terminal carries out the answer of confirmation to the fault detector that sends fault message.
6) fault detector acknowledges receipt of the letter in reply of communication terminal, if receive then power cut-off, otherwise enters step 7).
7) whether rolling counters forward reaches 6 times, if yes then enter next step, otherwise changes step 4) over to.
8) fault detector connection alarm is reported to the police, and the notice communication link is unavailable, and power cut-off.
The above is preferred implementation of the present invention, for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, and these improvements and modifications also are regarded as protection scope of the present invention.
