The beneficial effects of the utility model:
The utility model has been owing to having added clock module, and at any time monitoring time all can be arranged in paddy electricity period easily, patrols and examines power supply in addition and is defined as again low-frequency power, so not only checks and has ensured fire-fighting equipment but also saved to greatest extent electric cost expenditure.
The utility model selects PLC as control core, mature and reliable, and also PLC expansion is easy, makes function scale (fire pump quantity) expansion of cruising inspection system become very easy.Such as system will increase pressure, flow, liquid level control function, control hardware aspect only need increase the analog input module of one 4 input.User's the second investment is greatly reduced, and time and labour saving.
Man-machine interface of the present utility model is not only provided with the custom menus such as operation instruction, operational factor, parameter setting (password enters), and has configured abundant warning message.
Brief description of the drawings
Fig. 1 is theory diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, a kind of fire-fighting frequency conversion inspection controller with real-time clock function, it comprises manually patrols and examines signal input key, human-computer interaction interface, auxiliary reclay, variable-frequency power sources and PLC controller, described PLC controller comprises CPU and the clock module being attached thereto, human-computer interaction interface and manually patrol and examine signal input key all as the control signal input of inspection controller, human-computer interaction interface is all connected with the corresponding control signal input of CPU in PLC controller with the output of manually patrolling and examining signal input key, the control signal output of CPU is connected with the control signal input of patrolling and examining contactor by auxiliary reclay, the power control signal output of PLC controller is connected with the control signal input of variable-frequency power sources, the signal output of described variable-frequency power sources is the power supply of fire pump group by patrolling and examining loop contactor.The utility model has been owing to having added clock module, and at any time monitoring time all can be arranged in paddy electricity period easily, patrols and examines power supply in addition and is defined as again low-frequency power, so not only checks and has ensured fire-fighting equipment but also saved to greatest extent electric cost expenditure.
The utility model also comprises power frequency supply, the control signal input of power frequency supply is connected with fire-fighting start and stop button, the output of power frequency supply is the power supply of fire pump group by fire-fighting major loop contactor, this fire-fighting major loop contactor with patrol and examine loop contactor interlocking, in the time that fire-fighting major loop contactor is opened, be that fire pump group is powered by power frequency supply, patrol and examine loop contactor and disconnect, variable-frequency power sources stops as the power supply of fire pump group.
PLC controller of the present utility model also comprises digital module and analog module, and digital module and analog module are connected by contact pin slot or expansion cable with CPU.The utility model selects PLC as control core, mature and reliable, and also PLC expansion is easy, makes function scale (fire pump quantity) expansion of cruising inspection system become very easy.Such as system will increase pressure, flow, liquid level control function, control hardware aspect only need increase the analog input module of one 4 input.User's the second investment is greatly reduced, and time and labour saving.
Human-computer interaction interface of the present utility model is connected with CPU by private cable.
PLC controller of the present utility model connects by RS485 communication interface Yu Xiaokong center.
Man-machine interface of the present utility model is not only provided with the custom menus such as operation instruction, operational factor, parameter setting (password enters), and has configured abundant warning message.
The course of work: first in man-machine interface, arrange monitoring time (specifically comprise what day, some, somewhat), then arrange patrol and examine operation duration, patrol and examine interval duration.(in man-machine interface, any value of setting all has certain scope that arranges, and can not arrange arbitrarily, has prevented so on the one hand mistake setting, has ensured on the other hand safety economy.) PLC patrols and examines according to these conditions.In the time arriving the time point of setting, PLC turns round with setting speed by Output Interface Control First fire pump, operation duration then, First fire pump is patrolled and examined end, enters interval loitering phase, patrols and examines when interval duration then starts second fire pump, the like, circulation is gone down, and last fire pump is patrolled and examined end by the time, just enters the next one and patrols and examines latent period.It is other that fire-fighting order in any case has limit priority, in the time that fire-fighting start and stop press switch to open, fire-fighting major loop contactor is opened, be that fire pump group is powered by power frequency supply, patrolling and examining loop contactor disconnects, variable-frequency power sources stops as the power supply of fire pump group, no matter patrols and examines and proceed to all interruptions immediately of any step while receiving fire-fighting order, proceeds to rapidly fire-fighting operational mode.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
