Background
Counting has wide application in industrial production, including the fields of quantity statistics, quality control, equipment maintenance and the like. The prior art scheme generally adopts a switching value sensor for counting, and has a mechanical type, a photoelectric induction type and the like. For example, when an on-off sensor is attached to a fixed member and another operating member is close to the fixed member, the on-off sensor outputs a first state, and when the operating member is far from the fixed member, the on-off sensor outputs a second state. The counting principle is that the output state of the switching value sensor is changed by the action of the moving part, so that the switching value sensor outputs an on or off signal, and then the signal is accessed into a control unit such as a PLC (programmable logic controller), a PC (personal computer) and the like to complete the counting of the moving times of the moving part.

However, due to the existence of the gap, some external interference may affect the counting result, resulting in low accuracy. For example, in the case of a mechanical switching value sensor, counting can be stopped by simply pressing the contact of the switching value sensor with an adhesive tape or a steel sheet.

In the present embodiment, a counting method is provided, which can be used in the information processor, and fig. 3 is a flowchart of the counting method according to the embodiment of the present invention, as shown in fig. 3, the flowchart includes the following steps:
and S11, alternately receiving the first identification information sent by the first transmitter and the second identification information sent by the second transmitter.
Wherein the first emitter is fixed to the first member, the second emitter is fixed to the second member, and the second member is adapted to reciprocate relative to the first member.
For the principle of the alternate reception, please refer to the related description of the embodiment shown in fig. 2, which is not repeated herein.
The first identification information and the second identification information can be specifically set according to actual conditions, no limitation is imposed on the setting, and only the first identification information and the second identification information are required to be different.
S12, counting the number of movements of the second member based on the first identification information and the second identification information alternately received.
After receiving the first identification information and the second identification information, the information processor judges whether the identification information is from the first component A or the second component B through the internal processor, and then selects an appropriate time to count. For example, a count of 1 is performed each time the identification information changes from coming from the first component a to coming from the second component B.
To ensure the accuracy of the counting result, the transmission time interval of the first transmitter 10 and the second transmitter 20 may be set to be smaller than the approach time and the departure time in the reciprocating motion of the second block B.
According to the counting method provided by the embodiment, the first identification information transmitted by the first transmitter and the second identification information transmitted by the second transmitter are alternately received, the first transmitter is fixed on the first component, the second transmitter is fixed on the second component, the number of times of movement of the second component can be counted by using the received first identification information and the received second identification information, and the problem of inaccurate counting caused by external interference can be avoided because the transmitter transmits the identification information instead of the level signal.
In the present embodiment, a counting method is provided, which can be used in the information processor, and fig. 4 is a flowchart of the counting method according to the embodiment of the present invention, as shown in fig. 4, the flowchart includes the following steps:
s21, receiving the first identification information and the second identification information.
The first identification information and the second identification information have uniqueness, and after the counting device is installed, the first identification information and the second identification information can be sent to the information processor, so that the information processor can know the first identification information and the second identification information.
And S22, matching the first component and the second component by using the first identification information and the second identification information.
The information processor, after receiving the first identification information and the second identification information, corresponds the first identification information to the first component, corresponds the second identification information to the second component, and matches the first component with the second component. Any identification information that is not subjected to identification matching is considered invalid information in the subsequent counting process.
And S23, alternately receiving the first identification information sent by the first transmitter and the second identification information sent by the second transmitter.
Wherein the first emitter is fixed to the first member; the second emitter is fixed to a second member and the second member is adapted to reciprocate relative to the first member.
Specifically, the first identification information and the second identification information may be identification information subjected to encryption processing, so as to prevent a third party from intercepting the first identification information or the second identification information to produce a forged component to interfere with counting.
For example, the first identification information is obtained by encrypting with a first encryption algorithm, and the second identification information is obtained by encrypting with a second encryption algorithm. The specific encryption algorithm and the encryption form may be specifically set according to the actual situation, and are not limited herein.
For the rest, please refer to S11 in the embodiment shown in fig. 3, which is not described herein again.
S24, counting the number of movements of the second member based on the first identification information and the second identification information alternately received.
In this embodiment, the second identification information further carries a timestamp for indicating a sending time. This is because encryption of fixed content alone is not sufficient to protect against forgery, because a forger can directly resend the intercepted encrypted information. To solve this problem, time synchronization may be performed when the components are matched in S22, and a time stamp may be carried in the second identification information and then encrypted. Thus, the second identification information is different for each transmission. Specifically, the above S24 includes the following steps:
s241, decrypting the second identification information to obtain the timestamp.
And the information processor decrypts the second identification information after receiving the second identification information to obtain the timestamp carried in the second identification information.
And S242, judging whether the difference value between the current time and the timestamp is within a preset range.
When the difference between the current time and the timestamp exceeds the preset range, executing S243; otherwise, counting is performed.
S243, the second identification information is confirmed to be invalid, and the process returns to the step of executing S23.
In the counting method provided by this embodiment, the second identification information carries the timestamp and is encrypted, so that the second identification information sent by the second transmitter each time is different, and the identification information is prevented from being forged; meanwhile, the timestamp in the received second identification information is compared with the current time to determine whether the received second identification information is valid, so that the counting accuracy is improved.
As an alternative to this embodiment, in order to ensure the accuracy of time synchronization for a long time, the second transmitter may send time calibration information periodically to calibrate the time of the information processor. Specifically, the counting method further comprises:
(1) and receiving time calibration information sent by the second transmitter every preset time.
(2) The current time is calibrated based on the time calibration information.
The information processor, after receiving the time alignment information sent by the second transmitter, uses the time in the time alignment information to align the current time so as to avoid recognizing the second identification information as invalid information due to time asynchronization.
In the counting method provided by this embodiment, the second transmitter sends the time calibration information every preset time, so as to ensure the time accuracy for a long time.
Because the counting device works normally, the information processor is only in three states: (1) receiving first identification information; (2) the first identification information sent by the first transmitter is blocked, and the second identification information sent by the second transmitter is received; (3) and in a listening state during the information transmission interval.
Once the counting device is interfered by environment or man-made interference, the information processor still cannot receive the first identification information sent by the first transmitter after the interval time of information sending and cannot receive the second identification information sent by the second transmitter, and the counting device can be considered to be interfered.
Therefore, as another optional implementation manner of this embodiment, the counting method further includes:
(1) and judging whether the first identification information or the second identification information is received within a preset time interval.
(2) And when the first identification information is not received and the second identification information is not received within a preset time interval, confirming that interference exists in the current counting.
The counting method provided by the embodiment can improve the counting accuracy by automatically detecting the interference of the current counting environment.
Further, the counting method described in this embodiment further has a function of automatically detecting interference, specifically, when the real states of the first component a and the second component B are far away, simply blocking the propagation path from the first transmitter of the first component a to the information processor will not make the counting apparatus mistakenly think that the first component a and the second component B are close; conversely, when the true states of the first and second components a and B are close, simply blocking the propagation path of the second emitter of the second component B does not cause the counting device to mistakenly assume that the first and second components a and B are far apart. This is due to the 3 states of the processor, which do not result in false counts, and which are detected and recorded and transmitted when needed.
Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations fall within the scope defined by the appended claims.
