Abstract
The utility model discloses a control system for drainage of a metro. The control system comprises a PLC (Programmable Logic Controller) operating platform and a drainage pump, and is characterized in that the PLC operating platform is connected with a timing control device for opening or closing the drainage pump. According to the control system, the drainage pump can be regularly/periodically controlled, so that the drainage pump discontinuously operates to prevent reduction in service life of the drainage pump due to no action of the drainage pump for long time.
Description
Technical field
The utility model relates to a kind of control system of subway draining.
Background technique
The subway drainage system mainly can be divided into three types: i.e. sewage drainage system, waste water drainage system and drainage system against rain.Nowadays all be automatic control for above-mentioned three kinds of drainage systems.
All need to relate to the draining water pump in three group systems, the draining water pump is that transmission by hyperacoustic signal realizes automatic control now, be broadly divided into dual mode: the one, ultrasonic level gage is installed in the sump, then obtain signal from water level switch by PLC, after signal had reached the water level that debugging is got well in advance, the draining water pump will be driven/be stopped to the respective switch in the control system automatically.The 2nd, ultrasonic level gage is installed in the sump, and PLC obtains the water level signal from the ultrasonic level gage in the sump, is then automatically controlled the operation of draining water pump by the PLC control system.
All be to utilize the mutual transmission of ultrasonic signal and control system to control the ON/OFF of draining water pump in the above-mentioned dual mode, but a very long time is not moved the words of water pump in sump, the insulation resistance of the motor in these draining water pumps just has a certain amount of decline so, if things go on like this will have influence on the life-span of water pump and the normal operation of control system.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of control system of subway draining, this control system can the timing/phase control draining water pump, make the operation of draining water pump discontinuity, to descend the working life of avoiding the draining water pump not move for a long time causing the draining water pump.
For realizing above-mentioned technical purpose, the utility model is achieved by following technical proposals.
A kind of control system of subway draining comprises the PLC operating platform, and draining water pump, described PLC operating platform are connected with for the timing control apparatus of opening or closing described draining water pump.
In the technique scheme, described PLC operating platform comprises central processing unit (CPU), and described central processing unit (CPU) is connected with programmable device, described central processing unit (CPU) also is connected with first memory and second memory.
The beneficial effects of the utility model are, by this drainage system, can artificially set first a time during use, impel timing control apparatus according to the time operation of setting, the draining water pump just can be realized the running of discontinuity like this, increases the working life of draining water pump.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of PLC operating platform in the utility model.
Embodiment
Be described in further detail below in conjunction with the control system of description of drawings to a kind of subway draining of the utility model.
Referring to Fig. 1 ~ Fig. 2, a kind of control system of subway draining, comprise PLC operating platform 1, described PLC operating platform 1 comprises central processing unit (CPU) 2, and described central processing unit (CPU) 2 is connected with respectively programmable device 3, input circlult 4, output circuit 5, first memory 6, second memory 7.
The control system of described subway draining also comprises draining water pump 8, is connected with between described PLC operating platform 1 and the described draining water pump 8 for the timing control apparatus 9 of opening or closing described draining water pump 8.By described timing control apparatus 9, can control described draining water pump 8, make the running of draining water pump 8 discontinuity, prevent that described draining water pump 8 from not operating for a long time and the problem that causes reducing working life.
The specific works principle is as described below: at first input circlult 4 is transferred in the central processing unit (CPU) 2, first memory 6 sends in the central processing unit (CPU) 2 with the information of second memory 7 simultaneously, then by programmable device 3 corresponding working procedure is inputted, then be arranged to the time of needs at timing control apparatus 9, so just can realize the running of draining water pump 8 discontinuity.
Claims (2)
1. the control system of a subway draining, comprise PLC operating platform (1), draining water pump (8) is characterized in that, described PLC operating platform (1) is connected with for the timing control apparatus (9) of opening or closing described draining water pump (8) with described draining water pump (8).
2. the control system of a kind of subway draining according to claim 1, it is characterized in that, described PLC operating platform (1) comprises central processing unit (CPU) (2), described central processing unit (CPU) (2) is connected with programmable device (3), input circlult (4), output circuit (5), and described central processing unit (CPU) (2) also is connected with first memory (6) and second memory (7).
