In one embodiment, a method for managing a tool is provided, which is applied to the tool management device provided in the foregoing embodiment, as shown in fig. 5, and includes the following steps:
s1, after a certificate of a user is identified through a card reader, the singlechip sends the acquired certificate ID to a site computer; the field computer is used for carrying out data conversion on the certificate ID, comparing the certificate ID after the data conversion in a preset ID library, and judging whether the certificate ID is in the preset ID library or not;
s2, after the on-site computer judges that the certificate ID is in a preset ID library, the singlechip receives a first control instruction sent by the on-site computer and sends an unlocking control signal to the electric control lock, so that the electric control lock drives a movable cabinet door of the tool cabinet body to be opened;
s3, after a preset time interval, the singlechip acquires state information of the electric control lock;
s4, if the state of the electric control lock is an unlocking state, the singlechip sends a first control signal to the alarm lamp, so that the alarm lamp displays a corresponding color of a preset unlocking state;
s5, if the state of the electric control lock is a locking state, the singlechip sends corresponding control signals to the multiple multi-path relays, and scans the multi-layer tool supporting plates in the cabinet body of the tool cabinet layer by layer to obtain the current scanning result of the tool in the cabinet body, and sends the current scanning result to the field computer; the on-site computer is used for comparing the current scanning result with the stored last scanning result and checking the condition of taking out or replacing the current measuring tool;
s6, when the site computer calculates that the replacement situation is that all the workers are replaced by using the measuring tool, the singlechip receives a second control instruction sent by the site computer and sends a second control signal to the alarm lamp, so that the alarm lamp displays corresponding colors of all the replacement results;
and S7, when the site computer core calculates that the replacement condition is that the using tool is not replaced completely, the singlechip receives a third control instruction sent by the site computer and sends a third control signal to the alarm lamp, so that the alarm lamp displays corresponding colors of the preset replacement result.
Further, the singlechip sends corresponding control signals to a plurality of multipath relays, scans the multilayer tool measuring tool supporting plate in the cabinet body of the tool cabinet body layer by layer, and specifically comprises:
step (1), a singlechip sends corresponding control signals to a plurality of multi-path relays, so that each multi-path relay simultaneously gates the sensing parts on a first layer of tool supporting plate and obtains the sensing result of each sensing part on the first layer of tool supporting plate;
and (2) continuously repeating the step (1) to enable each multi-path relay to simultaneously gate the sensing components on other layers of the tool supporting plates, and acquiring the sensing result of each sensing component on the tool supporting plates until the sensing result of each sensing component on each layer of the tool supporting plates is acquired.
Further, the field computer is further configured to:
recording personnel names and card swiping time corresponding to the certificate ID;
and storing the current scanning result in a database, and assigning the current scanning result to the last scanning result.
Because the name of the person corresponding to the certificate ID and the card swiping time are recorded every time, when the work tool is lost, the responsible person can be conveniently found.
Further, the preset time interval may be set according to actual conditions.
Another flow chart of the above method can be seen in fig. 6, and the flow can be expressed as follows:
the operator holds the on-duty card and swipes the card at the card reader, the card reader reads the card number of the on-duty card, and the data is sent to the site computer in a 16-system mode through the serial port; after receiving the data, the on-site computer converts the data and then compares the data with an ID library of the computer end, and if the data is in the ID library, the on-site computer gives a door opening instruction and records the name and card swiping time of the person corresponding to the ID data. After receiving the door opening instruction, the singlechip controls the relay to drive the electric control door lock to open the movable door of the tool cabinet; at the moment, an operator can take out or put back the tool, and the movable door is manually closed after the operation is finished; after 1 minute, if the state of the electric control lock is on, the movable door is considered to be not closed, the singlechip drives the relay to control the alarm lamp to display red, and if the singlechip detects that the state of the electric control door lock is changed from on to off, namely, a rising edge signal, the scanning program is started.
The scanning program controls the relay to turn on the circuit row by row for the singlechip, checks whether the working tool is positioned row by row, and uses whether the working tool presses the micro switch as a detection signal. The single chip microcomputer sequentially sends the scanning results to the field computer, and after the field computer receives all data in a timing period, the field computer compares all data with the last result and calculates the current taking-out and returning situation. The computer gives an instruction to the singlechip and stores the result in the database, if the measuring tool is completely replaced, the singlechip drives the relay to enable the alarm lamp to display green, and if the measuring tool is not completely replaced, the alarm lamp displays yellow; and finally, assigning the current result to a last variable for next comparison.
One commonly used singlechip is STC89C52RC, the IO port pins of the singlechip are divided into 4 groups of 8, and the total number of the IO port pins is 32; when the number of the tools exceeds 32, a singlechip cannot use a method for monitoring one tool through each IO port. In addition, 3 IO mouthfuls of singlechip still need control alarm lamp, and 5 IO mouthfuls control card reader, 1 IO mouth control lock state, and 2 IO mouthfuls are used for serial communication.
The embodiment of the present example given for the scanning mode of the tool is a matrix scanning mode. The matrix scanning mode can be a point-by-point scanning method (various proximity switch triggers), but when the tool is taken more, no detection or false detection can be caused by adopting the mode.
Thus, the present embodiment adopts the progressive scanning method shown in fig. 7: p1-0 to P1-4 are singlechip IO ports, and respectively control 4 groups of 5-way relays (or triodes or mos field effect transistors). In fig. 7, each small triangle is one path of a multi-path relay. The single chip microcomputer controls the multi-path relay to be firstly connected with P0-0 to cut off others, so that each row of multi-path relay has only a first path to be opened, and other paths are scanned, and P1-0 to P1-3 are scanned, so that the working tool state in the first row is determined; then P0-1 is switched on, the other is switched off, and the state of the second measuring tool is determined; and so on, progressive line-by-line scanning.
