In particular, advanced science in military equipment is an important factor directly related to the national power and security of the country, and continuous research / development is required.

1 schematically shows a coal feed control system that has been developed by the inventor.

Referring to FIG. 1, a coal supply control system controls a system as a whole, a fire control device 110 for controlling a final trigger, and a coal supply to perform any shot transport related control according to the command of the fire control device 110. The control device 120, a bombardment rod 130 for loading the arbitrary shots, a bullet feeder 140 for transferring the bullets of the bombardment rod 130 to a tray (not shown), and A transmission / load control unit 150 for transport and loading and an electric motor driving unit 160 for driving the corresponding motor according to the command of the coal supply control device 120 are provided.

Here, the coal feed control device 120 includes a coal feed control program unit 121 having a built-in coal feed control program and comprising a central processing unit (CPU), and a filter unit having servo amplification and emergency alert interfaces 122a and 122b. And a relay unit 123 having input and output relays 123a and 123b, and a power supply unit 124 for supplying power to the system. The coal feed control program unit 121 is provided with a coal feed control program, a control environment setting program, and a downloading data execution program. In addition, the feed / load control unit 150 has a transfer key for inputting a command for transferring the bullet of the bombardment 130 to the tray, and a command for loading the bullet of the tray into the bombardment 130. A stacking key for input, a transporter alignment key for inputting a command for aligning the bullet feeder 140, a coal transport key for inputting a command for transferring the transported shot to a predetermined position, and the like. It is prepared. Here, in particular, when it is in a state capable of receiving and processing commands by all the above keys, this indicates a case where there is no abnormality in the system, and all operations of the system are automatically performed according to the set control program. In addition, when the conveyor alignment key and the coal delivery key are not available among the keys, this indicates a case where an abnormality has occurred in the system, and the operation of the system is semi-automatically performed.

In the shot control system having the above configuration, communication is made every 40 msec between the fire control device 110 and the fire control device 120, the transmission control device 120 communicates with the fire control device 110. Receives a command for driving the bullet transporter 140 through. When the communication chip is used for the communication of the bullet control device 120 as described above, if the communication chip does not receive a communication interrupt (interrupt) occurs or the communication is not received from the fire control device 110, The coal feed control device 120 needs to perform control so that an operator can determine that the communication of the coal feed control device 120 is stopped by checking such a state.

The present invention was created in view of the necessity of immediate action in the communication disconnection state as described above, and checks an error in communication by checking a frame reception state during communication between the fire control device and the coal fire control device in the coal fire control system. It is an object of the present invention to provide a communication error check and control method in a coal briquette control system that can quickly return a communication data to a receivable state.

In order to achieve the above object, a communication error check and control method in a coal transmission control system according to the present invention includes: determining whether an automatic mode of the coal emission control system; Incrementing a program operation count and a communication response confirmation count for a predetermined time when the bullet control system is in an automatic mode; Comparing the program operation count at the reference time point with the program operation count after a predetermined time elapses; Recognizing a communication chip down state if the program operation count at the reference time coincides with the program operation count after a predetermined time elapses; Recognizing a communication disconnection state if the communication response acknowledgment count is continuously increasing; And re-initializing the communication chip and resetting the program operation count and the communication response confirmation count.

According to the present invention as described above, since the down state of the communication chip or the disconnection state of the communication chip is checked and correspondingly processed through the program operation count and the communication response confirmation count, communication errors can be accurately detected and the system is abnormal. This has the advantage of being able to act quickly when this happens.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 and 3 show a communication error check and control process according to the communication error check and control method in the coal feed control system according to the present invention, Figure 2 is a flow chart for checking the down state of the communication chip, 3 is a flow chart for checking the communication reception interruption state in the fire control apparatus.

Referring to FIG. 2, the CPU first determines whether the system is in auto mode (step 211). In this determination, the program is immediately terminated if it is not in the automatic mode, and in the automatic mode, it is determined whether the program operation count is zero (step 212). In this determination, if the program operation count is zero, it is determined whether the communication frame reception count is zero. If the communication frame reception count is not 0 in this determination, it means that communication reception is in progress, and thus the communication interrupt progress count is stored in the communication status check count (step 214). Here, the description will be supplemented with respect to the communication frame. The communication frame is composed of certain bytes according to the specified protocol.If there is no change in the frame reception counter which checks whether all frames have been received during the reception of the frame, that is, if the data is kept fixed with the constant data, the communication chip is interrupted The routine will detect this and read data from the communication data receive buffer. At this time, the communication progress counter is placed in the last part of the communication service routine to increase the count each time a frame is received.In the bullet control unit check routine, the count is checked after about 3 seconds. It is determined that the communication chip is down when the counts after the second match.

When the storage in step 214 is completed, the program operation count is increased for a predetermined time (e.g., 3 seconds) (step 215). This is to check the communication condition when executing program operation for 3 seconds. At this time, the execution time of one program operation is about 12msec. On the other hand, when the program operation count is not 0 in step 212 and when the communication frame reception count is 0 in step 213, the program proceeds to step 215, respectively.

In this manner, the program operation counting is continued for 3 seconds to determine whether the count number is 250 (step 216). If the number of program operation count counts is 250 in this determination, it is determined whether the communication state check count count coincides with the program operation count count 250 (step 217). If the number of communication state check counts in this determination coincides with the number of program operation counts, the communication stop state flag is set and the communication chip is initialized (step 218). Then, the program operation count and the communication state check count are reset (step 219). If the number of communication state check counts does not match the number of program operation counts in step 217, the program is immediately proceeded to step 219 to reset the program operation counts and the communication state check counts.

On the other hand, when the reset in step 219 is completed, it is determined whether the communication stop state flag is set (step 220). Here, even if the number of program operation counts is not 250 in step 216, the program is immediately proceeded to step 220 to determine whether the communication stop state flag is set. If the communication stop state flag is set in this determination step 220, the communication lamp is turned off and the communication lamp off flag is set (step 221). Then, it is determined whether the communication lamp light off flag is set (step 222). If the communication stop state flag is not set in step 220, the controller resets the program and proceeds to step 222. If the communication lamp light off flag is not set in step 222, the program is reset. If the communication lamp off flag is set, it is determined whether the communication stop state flag is set (step 223). In this determination, if the communication stop status flag is set, the program ends immediately. If the communication stop state flag is not set, the communication lamp is turned on and the communication lamp light off flag is reset (step 224). In this way, communication is resumed normally by checking and resetting the communication chip down state.

Then, with reference to Figure 3 will be described with respect to the inspection and the reset process for the communication reception interruption state in the fire control device.

Referring to FIG. 3, as in the checking of the communication chip down state of FIG. 2, the CPU first determines whether the system is in the automatic mode (step 311). In this determination, the program is immediately terminated if not in the automatic mode, and in the automatic mode, the communication response confirmation count is increased for a predetermined time (for example, 3 seconds) (step 312). In other words, in the bullet control unit routine, the communication response confirmation count is continuously increased for about 3 seconds. In the communication interrupt routine, when an interrupt occurs and the proper communication response processing is performed after receiving all data, the communication response confirmation count is reset. .

Then, it is determined whether the communication response confirmation count is continuously increasing (step 313). In this determination, if the communication response confirmation count continues to increase, the communication stop status flag is set, the communication response confirmation count is reset, and the communication chip is initialized (step 314). That is, if normal communication is performed every 40 msec between the fire control device 110 and the coal fire control device 120, the communication response check counter remains in the reset state, and thus the communication interruption processing in the coal fire control unit routine is not performed. However, since the response check counter cannot be reset when the communication between the fire control device 110 and the bullet control device 120 is lost, the communication response check count is continuously increased in the bullet control unit routine to confirm the communication response for about 3 seconds. If the count is continuously increasing, that is, there is no communication interrupt response processing, it is determined that the communication reception is lost.

When the initialization of the communication chip is completed, it is determined whether the communication stop state flag is set (step 315). If the communication response confirmation count is not continuously increased in step 313, the program proceeds to step 315 immediately. If the communication stop state flag is set in step 315, the communication lamp turns off and the communication lamp turns off flag is set (step 316). Then, it is determined whether the communication lamp light off flag is set (step 317). If the communication stop state flag is not set in step 315, the controller resets the program and proceeds to step 317. If the communication lamp light off flag is not set in step 317, the program is reset. If the communication lamp off flag is set, it is determined whether the communication stop state flag is set (step 318). In this determination, if the communication stop status flag is set, the program ends immediately. If the communication stop state flag is not set, the communication lamp is turned on and the communication lamp light off flag is reset (step 319). In this way, communication is normally resumed by checking and resetting the communication disconnection status in the fire control apparatus.

The program for checking communication interruption status in the communication chip down and fire control devices as described above is a method of checking the operation status of the communication chip and a specific chip that performs continuous operation. Applicable where not necessary. In most cases, after the time is determined using a timer interrupt, an interrupt is generated every corresponding time, and the same function as described above is performed. A routine for performing continuous operations in a program without using a timer interrupt is performed. If used, it can be used similarly to the timer function.

As described above, the communication error check and control method in the coal transmission control system according to the present invention checks and responds to the down state of the communication chip or the disconnection state of the communication chip through a program operation count and a communication response confirmation count. Therefore, it is possible to accurately detect an error in communication, and there is an advantage in that it can quickly act when an abnormality occurs in the system.
