Motor, one one is used as spare motor as the motor used on ordinary days, and be arranged in use even so on ordinary days
When motor breaks down, it can directly open spare motor and carry out using still, since each grey library system needs standby set
Two motor, have also increase accordingly cost of investment, and the Electric Motor Monitoring System of the application, since each motor does not limit to
In corresponding one grey library system, the linkage control to multiple motor may be implemented, because of the motor excessive without setting,
And then save investment.
Following is embodiment of the present invention method, can be used for apparatus of the present invention embodiment.For embodiment of the present invention method
In undisclosed details, please refer to apparatus of the present invention embodiment.
The embodiment of the invention provides a kind of motor monitoring method, method flow diagram such as Fig. 8 A, Fig. 8 B and Fig. 8 C institute
Show, this method can be applied in the master control set of Electric Motor Monitoring System shown in fig. 1 or fig. 2, the motor monitoring method
May include:
(1) when monitoring device requires starting motor mechanism on the spot for any one, method flow diagram is as shown in Figure 8 A:
Step 801 obtains the enabled instruction that monitoring device is sent on the spot.
It is main when monitoring device sends the request of starting motor mechanism to master control set by the first communication module on the spot
The second communication module for controlling device obtains the enabled instruction that monitoring device is sent on the spot, and the enabled instruction is sent at second
Manage device.
Can the motor mechanism that step 802, judgement currently have been started up satisfy the use demand.
Second processor in master control set can judge currently to have been started up while receiving the enabled instruction
Can motor mechanism satisfy the use demand, that is to say, that judging whether to need to restart a spare motor mechanism can
To meet the requirement for currently needing monitoring device on the spot to be started.
If step 803, the motor mechanism currently having been started up cannot satisfy the use demand, it is standby to start the first cis-position
With motor mechanism, and the first cis-position spare motor mechanism is connected to monitoring device on the spot.
It should be noted that the first cis-position spare motor mechanism is inactive motor mechanism at present, and
The motor mechanism of starting is adjacent.
Further, it can also judge whether the first cis-position spare motor mechanism starts success；
If the first cis-position spare motor mechanism does not start success, it is standby to issue fault alarm, the second cis-position of starting
With motor mechanism, and the second cis-position spare motor mechanism is connected to monitoring device on the spot.When the second cis-position is spare electronic
Machine mechanism starts successfully, then startup program terminates, and completes starting；When the second cis-position spare motor mechanism start it is unsuccessful, then
Fault alarm is issued, startup program terminates.
If step 804, the motor mechanism currently having been started up are able to satisfy use demand, by what is had been started up at present
Motor mechanism is connected to monitoring device on the spot.
(2) when monitoring device requires to close motor mechanism on the spot for any one, method flow diagram is as shown in Figure 8 B:
Step 805 obtains the halt instruction that monitoring device is sent on the spot.
It is main when monitoring device sends the request for closing motor mechanism to master control set by the first communication module on the spot
The second communication module for controlling device obtains the halt instruction that monitoring device is sent on the spot, and the halt instruction is sent at second
Manage device.
The motor mechanism having been started up is shut down in step 806, judgement, and other motor mechanisms having been started up are not made
Can processing satisfy the use demand.
Second processor in master control set can judge that shutting down one has opened while receiving the halt instruction
Can dynamic motor mechanism, other motor mechanisms having been started up deal with and satisfy the use demand.
If step 807 shuts down the motor mechanism having been started up, other motor mechanisms having been started up are not made
Processing satisfies the use demand, then shuts down the motor mechanism being connected to monitoring device on the spot.
If step 808 shuts down the motor mechanism having been started up, other motor mechanisms having been started up are not made
Processing is unsatisfactory for use demand, then by the motor mechanism being connected to monitoring device on the spot and the access between monitoring device on the spot
It disconnects.
(2) when generation emergency case requires to close the motor mechanism being all currently running, method flow diagram is as schemed
Shown in 8C:
Step 809 obtains any one monitoring device or the stop command itself sent on the spot.
When the first scram button in any one on the spot monitoring device or the second scram button on master control set are pressed
When lower, which is got by the first communication module of monitoring device on the spot or the second communication module of master control set, and
The stop command is sent to second processor.
