The advantages of transfer rate is fast, has become most widely used fieldbus in the world.
But existing load current detection controller, typically by allowing high pressure conductive track by Current Mutual Inductance coil, leads to
Magnetic field mutual inductance effect is crossed, mutual inducing current is produced in mutual inductor, by the voltage signal of Current Mutual Inductance coil output and outer
Connecting resistance calculating mutual inducing current, so as to obtain the electric current on high-tension line.But this kind of method is cumbersome, and detect small current letter
Number when, deviation is larger.And when main controller module crashes, communication cable is damaged or other reasonses cause signal of communication to interrupt
When, the outfan of input/output module remains in that original state, to voltage acquisition unit sending signal, the signal for collecting
Master controller can not effectively be sent to, cause to can't detect position, it is impossible to the electric current that effectively monitoring is loaded, be particularly some large-scale
Industrial and mining establishment, load current can not to effectively detection and ensure there is potential safety hazard.
For the problem in correlation technique, effective solution is not yet proposed at present.
Utility model content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of load current based on CAN
Long-distance monitor and control device, can solve the problem that existing load current long-distance monitor and control device is present and detects loaded down with trivial details, deviation is big, can't detect
The technical problems such as position.
For realizing above-mentioned technical purpose, what the technical solution of the utility model was realized in：
A kind of load current long-distance monitor and control device based on CAN, including master controller, the master controller difference
It is connected with power module, gsm communication module, CAN panel and analog to digital conversion circuit；The CAN panel includes
Watchdog circuit and input/output module, the outfan of the input/output module are connected with the input of watchdog circuit, are seen
The outfan connection sample circuit of door Canis familiaris L., the sample circuit connection load circuit and signal amplifier, the signal amplifier
Connection rectification circuit, rectification circuit connection analog to digital conversion circuit；The master controller is upper with distal end by gsm communication module
Machine is communicated to connect.
The signal amplifier connects a voltage comparator, and the voltage comparator connects external reference voltage.
The master controller passes through CAN communication cable connection with CAN panel.
The beneficial effects of the utility model：Design simplifies, easy to use, remote controlled, and is seen by being provided with
The CAN panel of door Canis familiaris L., when master controller crashes, communication cable is damaged or other reasonses cause signal of communication to interrupt
When, whole system can be forced to reset, effectively eliminate the hidden danger that can't detect position, it is ensured that the safe handling of load.
