Abstract

The invention provides a keep-alive detection method of a 5G short message all-in-one machine, which comprises the following steps: after the system is started, a monitoring thread is added besides the normal working thread, the monitoring thread is responsible for monitoring the state of the equipment, when the equipment runs abnormally, system information is sent, the system realizes resetting processing again, and the effect of keeping alive is achieved. The method can effectively avoid the problem of untimely short message receiving and sending caused by abnormal stop of the short message module, not only can ensure the normal operation of the equipment, but also can greatly reduce the labor cost of equipment maintenance.

Description

Keep-alive detection method for 5G short message all-in-one machine

Technical Field

The invention relates to the field of short message communication, in particular to a keep-alive detection method of a 5G short message all-in-one machine.

Background

At present, a mobile phone is the most common portable communication tool applied by people, short messages also become the most direct and effective communication mode, and compared with the short message receiving and sending of a mobile phone, a short message sending and receiving integrated machine is quicker in short message receiving and sending, easier to operate, higher in safety and reliability and more convenient in data storage, so that the short message sending and receiving integrated machine is widely applied to aspects of company meeting notification, natural disaster early warning, dynamic code sending, data acquisition, hydrology monitoring, disaster relief and emergency rescue and the like.

However, when the short message module in the short message all-in-one machine stops working due to static electricity, current fluctuation, firmware bugs and other factors, the short message all-in-one machine may be deployed in an unattended machine room or other remote places due to some special requirements, and if the module cannot be found to stop working and be recovered to be normal in time, the receiving and sending of the short message are delayed, so that information acquisition or notification sending cannot be performed in time.

Therefore, when the working state of the equipment module is abnormal, it is very important that the system can recover the normal working state as soon as possible.

The normal work flow of the system comprises the following steps: and starting the system, performing module initialization operation through the serial port connection module, and starting a normal working thread (receiving a user instruction to send a short message, reading the module short message and informing a user).

The system software and the module communicate through AT commands, and whether the working state of the module is normal can be judged by sending the mode that the AT obtains the OK response. There are several situations where the AT command waits for a return: and returning OK in time, returning in time but not OK, not returning after overtime, and other unknown exceptions. Only timely return OK is in the normal state.

In normal work, the operation of the serial port belongs to an exclusive mode, and the operation can be performed only in one process.

Disclosure of Invention

In order to overcome the defects and shortcomings in the background technology, the invention provides a keep-alive detection method of a 5G short message all-in-one machine. The method can effectively avoid the problem of untimely short message receiving and sending caused by abnormal stop of the short message module, not only can ensure the normal operation of the equipment, but also can greatly reduce the labor cost of equipment maintenance.

The solution of the invention is as follows: after the system is started, a monitoring thread is added besides the normal working thread, the monitoring thread is responsible for monitoring the state of the equipment, when the equipment runs abnormally, system information is sent, the system realizes resetting processing again, and the effect of keeping alive is achieved.

Detailed Description

The following further describes the embodiments of the present invention with reference to the attached drawings

(1) A module monitoring thread is added outside the normal working thread of the system and is responsible for monitoring whether the working state of the equipment is normal or not;

(2) the monitoring thread and the normal working thread run simultaneously, an AT instruction is sent to the 5G module through the serial port, and a return value is obtained to judge whether the module works normally or not;

(3) the monitoring thread and the normal working thread are synchronized by using a software synchronization lock, so that the exclusivity of a serial port can be kept, and the interference to the normal working thread is avoided;

(4) monitoring by the monitoring thread in a timing detection mode, sending an AT instruction AT a fixed time, acquiring a corresponding return value, identifying a state which is not returned with OK in time as an abnormal state, and considering that the system runs abnormally once the abnormal state continuously appears for a limited number of times;

(5) when the monitoring thread judges that the equipment is abnormal, sending a global notification message to the system, and notifying the system to perform reset processing;

(6) and after the system obtains the reset message, closing the existing thread and carrying out initialization reset operation again.

Claims

1. A keep-alive detection method of a 5G short message all-in-one machine is characterized by comprising the following steps: after the system is started, a monitoring thread is added outside a normal working thread, the monitoring thread is responsible for monitoring the state of the equipment, when the equipment runs abnormally, system information is sent, the system realizes resetting processing again, and the effect of keeping alive is achieved:

(2) the monitoring thread and the normal working thread run simultaneously, and whether the module works normally is judged by instructing the serial port AT and obtaining an OK return as a module;

(4) monitoring by the monitoring thread in a timing detection mode, carrying out abnormal judgment on the state of not timely returning OK, and considering that the system runs abnormally once the abnormal state continuously occurs for a limited number of times;

2. The detection method according to claim 1, characterized in that: and using the AT instruction and obtaining the OK return as the judgment basis for the normal module.

3. The detection method according to claim 1, characterized in that: and the monitoring thread and the main thread adopt a synchronous lock mode to realize the sharing operation of exclusive equipment.

4. The detection method according to claim 1, characterized in that: the monitoring thread sets a mode of limiting times, and misjudgment caused by accidental conditions is avoided.
