To further optimize the above embodiment, the diesel one-touch starting device may further include: the second buzzer, the second buzzer with the output of IO firewood main control unit 21 is connected, is used for when IO firewood main control unit 21 control closes the position status indicator lamp and is bright, according to the sound control signal that IO firewood main control unit 21 sent carries out audible alarm.

To further optimize the above embodiment, the diesel one-touch starting device may further include: PLC fault indicator, PLC fault indicator with the main control unit 21 is sent out to the IO firewood output is connected, is used for when the main control unit 21 is sent out to the IO firewood receives the PLC fault information that the controller 22 sent is sent out to the IO firewood, according the fault indication instruction that the main control unit 21 was sent is sent out to the IO firewood is sent out and is sent out light to remind fortune dimension personnel to acquire the firewood and send out the parallel machine and take place the PLC trouble.

In order to realize monitoring of GOOSE communication status between the I/O diesel-emitting master controller 21 and each I/O diesel-emitting slave controller, the diesel-emitting one-key starting device may further include: and the communication fault indicator lamp is recorded as a second communication fault indicator lamp, and the second communication fault indicator lamp is arranged on a communication link between the I/O firewood sending master controller 21 and each I/O firewood sending slave controller and is used for emitting light when GOOSE communication between the I/O firewood sending master controller 21 and each I/O firewood sending slave controller is abnormal.

To further optimize the above embodiment, the diesel one-touch starting device may further include: and the emergency starting button is connected with the control end of the I/O diesel engine main controller 21 and is used for starting all diesel engine sets.

In practical application, operation and maintenance personnel can start the start of all on-site diesel generator sets by triggering the emergency starting button. According to the configuration of the diesel engine set, the diesel engine one-key starting device can be provided with two emergency starting buttons for respectively starting the diesel engine sets of the A1F176 engine room and the A1F77 engine room.

It should be noted that the I/O diesel engine main controller 21, the on-position status indicator lamp, the PLC fault indicator lamp, the second communication fault indicator lamp, the emergency start button, and the like are all integrated in the audible and visual alarm wall-mounted box.

In summary, the redundant monitoring device of the power monitoring system disclosed by the present invention may include, in addition to the audible and visual alarm device: one key starting drive is sent out to firewood, send out emergent start requirement for satisfying the firewood, because the site control center is far away from the firewood and send out the doubling machine control room, consequently set up a key starting drive is sent out to the firewood at data center, on the control function basis that does not influence original electric power monitored control system, increased the long-range start function to the firewood unit of sending out, in order to deal with double-circuit commercial power trip point, the firewood is sent out the doubling machine PLC trouble and is leaded to the unable automatically start-up of firewood unit (PLC system trouble), shorten the time of artificial manual start-up firewood unit, improve start-up efficiency.

In addition, by means of a one-key starting scheme (separated from a PLC system, an electric power monitoring system and the like) of the diesel engine, the diesel engine set is manually started through an emergency starting button, and the problem that the automatic control system is accidentally shut down can be solved.

To facilitate an understanding of the wiring principle of the I/O diesel fuel dispensing controller, the following description is made in detail.

Referring to fig. 5, a wiring diagram of an I/O diesel engine distribution controller in a diesel engine one-key starting device disclosed in the embodiment of the present invention is shown, each unit closing indication loop corresponds to one unit parallel switch cabinet, in detail, a connection relationship between a 1# unit parallel switch cabinet and a 6# unit parallel switch cabinet shown in fig. 5, and a connection relationship between an a-path output switch cabinet and a B-path output switch cabinet and the I/O diesel engine distribution controller, a PLC fault indication loop is shown in fig. 5, and a connection relationship between a 1# to 6# unit remote starting outlet (including standby) and an output terminal of the I/O diesel engine distribution controller is shown in fig. 5.

To facilitate an understanding of the wiring principle of the I/O diesel engine host controller, the following description is made in detail.

Referring to fig. 6, a wiring diagram of an I/O diesel engine master controller in a diesel engine one-key starting device disclosed in the embodiment of the present invention, the emergency starting button includes: a test button SB3 and a one-touch start button SB 4.

The one-key starting device for firewood comprises: 1# Unit pilot lamp N # Unit pilot lamps HR1 HR6, each unit pilot lamp connected with an I/O firewood emission master controller output terminal, see I/O firewood emission master controller output terminal 1-I/O firewood emission master controller output terminal 6 in FIG. 6.

The one-key starting device for firewood comprises: a way output closing indicator lamp HRA and B way output closing indicator lamp HRB, A way output closing indicator lamp HRA and IO firewood send out main control unit output terminal 7 to be connected, B way output closing indicator lamp HRB and IO firewood send out main control unit output terminal 8 to be connected.

The one-key starting device for firewood comprises: PLC fault indicator HY, PLC fault indicator HY and IO firewood main controller output terminal 9 are connected.
