Abstract
The invention discloses a remote-control outdoor cabinet air conditioner which can be used for monitoring the working condition of an unattended air conditioner and finding the faults of the air conditioner in time. The remote-control outdoor cabinet air conditioner comprises an air conditioner body and a monitoring alarm, wherein the air conditioner body is provided with a communication unit, a temperature sensor and a control unit; the monitoring alarm is separated from and communicated with the air conditioner body. The remote-control outdoor cabinet air conditioner is characterized in that the air conditioner body is further provided with a storage unit and a current sensor which is used for detecting the working current of a compressor in the air conditioner; a compressor working mode-working current range curve which takes a working mode as an index and takes compressor upper limit working current and compressor lower limit working current under the corresponding working mode as extreme values is pre-stored in the storage unit; the control unit is connected with each of the communication unit, the temperature sensor, the current sensor and the storage unit. The remote-control outdoor cabinet air condition is capable of finding the fault conditions such as compressor work abnormity and refrigerant lack in time and then carrying out corresponding remote alarm.
Description
Technical field
The invention belongs to air-conditioning technical field, be specifically related to a kind of remotely monitoring outdoor cabinet air-conditioning.
Background technology
In a lot of unattended occasion such as operating office, outdoor cabinet, being required for being applied to air-conditioning and to provide for the normal work of equipment to support, the work the most reliably and securely controlling air-conditioning just becomes the design challenges of engineers.The most a lot of outdoor cabinet air-conditionings are in normally open, temperature is detected by the temperature sensor of self, automatically start when temperature reaches threshold value and realize refrigeration or heat, although this kind of mode achieves the original intention of design to a certain extent, it is capable of predetermined temperature regulation, but if air-conditioning damages, then may result in serious consequence, it is therefore desirable to remotely the work to air-conditioning is monitored, finds the fault of air-conditioning in time and keep in repair.
Summary of the invention
The purpose of the present invention is to propose to a kind of remotely monitoring outdoor cabinet air-conditioning, unattended air conditioning condition can be monitored, find the fault of air-conditioning in time.
The remotely monitoring outdoor cabinet air-conditioning of the present invention includes being provided with communication unit, temperature sensor, the air conditioner main body of control unit and separates with described air conditioner main body and the monitoring siren of communication, it is critical only that described air conditioner main body is additionally provided with memory cell and for detecting the current sensor of the compressor operating electric current within air-conditioning, described memory cell prestores with mode of operation for index, with the compressor upper limit operation electric current under corresponding mode of operation and compressor lower limit operating current compressor operating pattern-current margin curve as extreme value；Described control unit is connected with communication unit, temperature sensor, current sensor and memory cell respectively.
The monitoring principle of above-mentioned long-range monitoring outdoor cabinet air-conditioning is as follows:
Described control unit unit utilizes the real-time working electric current of current sensor monitoring compressor, and compare with the compressor operating pattern-current margin curve under corresponding mode of operation, when real-time working electric current is beyond compressor operating pattern-current margin curve, control unit is sent a warning to monitoring siren by communication unit.Such as say, when the real-time working electric current of compressor is less than the minimum running current under this mode of operation, represent that this compressor the most normally works (not operating most probably) for compressor, and when the real-time working electric current of compressor is higher than the high workload electric current under this mode of operation, representing this overload of compressor, this status pole of long term maintenance may burn out compressor.Thus combine mode of operation and operating current, it is achieved that the monitoring to compressor operating state, find the situation that compressor fails normally to work in time.
Further, described air conditioner main body is additionally provided with the pressure sensor for detecting compressor snow kind pressure, described pressure sensor is connected with control unit, and described memory cell prestores the compressor snow kind pressure limit curve as extreme value with compressor upper limit snow kind pressure and compressor upper limit snow kind pressure.
Equally, described control unit unit utilizes the snow kind pressure of pressure sensor monitoring compressor, and compare with compressor snow kind pressure limit curve, when snow kind pressure is beyond compressor snow kind pressure limit curve, control unit is sent a warning to monitoring siren by communication unit.Thus achieve the monitoring to compressor snow kind pressure, find the situation that compressor snow kind is not enough in time.
Specifically, described communication unit is wireless communication module based on 2G, 3G, 4G, to improve remote communications capability.
The remotely monitoring outdoor cabinet air-conditioning of the present invention has prestored compressor operating pattern-current margin curve, a compressor snow kind pressure limit curve, and by corresponding sensor, operating current, the snow kind pressure of compressor are monitored in real time, the failure condition that compressor operating is abnormal and snow kind is not enough can be found in time, and carry out corresponding remote alarms, there is good practicality.
Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams remotely monitoring outdoor cabinet air-conditioning of the present invention.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention such as mutual alignment between the involved shape of each component, structure, each several part and annexation, the effect of each several part and operation principle etc. of the present invention is described in further detail.
