The mold operates in a periodic opening and closing state. The mold intelligent terminal mainly collects this periodic opening and closing state. In order to achieve statistical summary of at least one parameter such as equipment capacity, yield, utilization rate, etc.

As shown in Figure 11, the working mode of the mold smart terminal is: when the mold is running, the mold A panel will run from X to Y, and the reed switch on the mold B panel will sense the closing of the mold A and count the times. And timing.

As shown in Figure 12, the workflow of the mold smart terminal is:

S1, counting time. The magnetic induction module 101 triggers counting the number of times each time the mold is pressed, and the counting and timing unit 102 in the low-power main control chip 104 executes the +1 counting operation; the cycle time from the last pressing to the current pressing is recorded, This time is added to the total cycle time, and the accurate average cycle is calculated by combining the number of times to be reported, and the timing operation is performed. In order to prevent accidental jitter in the mold pressing process, combined with the minimum cycle item required, the low-frequency cycle count is automatically filtered to make the count more accurate, so that the mold count and time and other information statistics can be realized through the magnetic induction technology.

S2, anti-dropping. The anti-tamper module 108 can sense falling-off information, and when it senses falling-off, it will trigger a fall-off alarm, and upload the alarm information to the cloud platform through the NB-Iot communication module. The anti-dropping external sensor signal source is realized by the combination of a physical switch and an anti-dropping column. After the equipment is installed, as shown in Figure 13, the anti-dropping column (located in the circle) of the mold intelligent terminal 100a will be pressed against the U-shaped groove of the mold assembly 100b. When the mold intelligent terminal 100a falls off from the U-shaped part, the anti-dropping column will bounce up, triggering the fall-off signal.

S3. Report manually. As shown in FIG. 10, the mold smart terminal is provided with a button keyboard, and the worker can press the button to go through the active reporting process of the low-power main control chip 104 and manually report the working information of the device to the cloud platform.

S4. Power alarm. When the low power consumption main control chip 104 detects that the battery module 105 is in low power, it will report the low power status information of the device to the cloud platform.

Optionally, the NB module communicates wirelessly with the cloud platform and reports information.

In this embodiment, the mold intelligent terminal adopts magnetic induction technology, which makes the counting induction more accurate, and there is no jitter of the physical switch, which further meets the precise counting requirements; the use of radio frequency technology can greatly save the human and material consumption of the customer’s inventory. Batch and efficient long-distance reading is more cost-effective than barcode reading in related technologies; low power consumption technology can greatly save power consumption, and only two lithium batteries can replace a few watts of adapter power supply, which indirectly saves Cost and energy consumption; the physical anti-falling design makes the early warning of falling off more accurate and reliable.
