Embodiment
The utility model water heater pick-up unit detects by the service data to each parts of water heater,, in water heater overall test process or in the process of reprocessing the inquiry failure cause that water heater breaks down, can accurately determine the source of trouble, convenient maintenance.With reference to the accompanying drawings the embodiment of water heater pick-up unit described in the utility model is described in detail.
Water heater 11 comprises water heater master control borad 115 and the control panel 116 that is arranged at outer cover of water heater, is arranged at heating rod 111, temperature sensor 112 and flow sensor 113 in water heater liner.
Described control panel 116, temperature sensor 112 are connected with flow sensor and are connected with water heater master control borad 115 respectively, described heating rod 111 is connected with water heater master control borad 115 by relay (not shown), water heater master control borad 115 is according to the instruction of control panel 116, and the Data Control relay that gathers in conjunction with temperature sensor 112 and flow sensor 113 opens and closes.Its annexation, fixed form and the control mode of said apparatus is all identical with electric heater in prior art, repeats no more.
Wherein, the heating rod 111 in water heater 11 adopts the 220V Alternating Current Power Supply, and miscellaneous part adopts 5V or 12V direct current supply.
Water heater pick-up unit 12 comprises and connects successively service data acquisition component, communication parts 125, fault analysis and handling unit 126 and multimedia device 127, also comprises to the power supply unit (not shown) of said apparatus power supply.
Described power supply unit is used for rectification is carried out in the input of the AC power of outside 220V, filtering, output 5V or 12V DC voltage after voltage stabilizing.
As shown in Figure 1, the service data acquisition component is used for gathering the service data of water heater 11.Better, each device in described service data acquisition component all is connected with the corresponding component of water heater 11 by welding manner, and specifically, described service data acquisition component comprises:
AC voltage sampling unit 121, receive respectively on the power supply measurement point of the power supply measurement point of heating rod 111 in water heater 11 and electric heater 11, is used for gathering the alternating current of outside 220V and the supply voltage of heating rod 111.
DC voltage collecting unit 122, be connected with temperature sensor 112, flow sensor 113 and relay respectively, is used for gathering the steering order (being high level or low level) that above-mentioned parts receive, and direct current supply voltage.
Described information transmission unit 125 comprises serial communication modular and wireless communication module.
Wherein, serial communication modular is used for the service data information of the water heater 11 that AC voltage sampling unit 121, DC voltage collecting unit 122, pulse collection unit 123 and current acquisition unit 124 are gathered and carries out baud rate self-adapting, transfers to fault analysis and handling unit 126.
Wireless communication module comprises successively modulus conversion chip, information encoding-decoding chip, modem chip and the antenna that connects, be used for the judged result of hereinafter described fault analysis and handling unit 126 encode, modulation treatment, export with wireless.
Fault analysis and handling unit 126, by information transmission unit 125 and the communication connection of service data acquisition component, be used for judging that the service data of water heater 11 is whether in safe range, and according to judged result, feed back to information transmission unit 125, when breaking down, control multimedia device 127 and carry out the fault prompting.
Accordingly, 126 inside, fault analysis and handling unit comprise the fault judge module, and connected communication module and memory module (all not shown).The service data information of the water heater 11 that communication module reception information transmission unit 125 transmits, the standard service data that the fault judge module is stored according to memory module judges, if break down, failure message is fed back to information transmission unit 125, by information transmission unit 125, transfer to respectively Terminal Server Client (not shown) and multimedia device 127.
The function of described fault analysis and handling unit 126 can be the circuit realization of AT89V52 chip by comprising model.The basic comparing function that this realizes for single-chip microcomputer, repeat no more.
For instance, if during water heater 11 power cut-off, heating rod 111 starts voluntarily.The heating rod supply voltage that gathers according to AC voltage sampling unit 121 of fault analysis and handling unit 126 (220V is that heating rod heating, 0V are stopped heating); The steering order that water heater master control borad 115 is exported to relay (adhesive of high level pilot relay, low level control relay disconnect); The set of relay, reset mode (set be "on" position, reset be off-position) failure judgement source.If water heater master control borad 115 output high level, the source of trouble is water heater master control borad 115; If otherwise water heater master control borad 115 output low levels, and relay resets, and the source of trouble is relay.
Again for instance, during water heater 11 work, heating rod 111 starts, and water temperature is unchanged.Fault analysis and handling unit 126 judges at first as described above whether water heater master control borad 115 or relay are the source of trouble, if be not all the source of trouble, judge the relevant service data of temperature sensor 112 and heating rod 111, comprise water temperature information that temperature sensor 112 detects and the alternating voltage of DC voltage and heating rod 111.The threshold value if the DC voltage of temperature sensor 112 is above standard, temperature sensor 112 is the source of trouble; If the DC voltage of temperature sensor 112 is in level threshold value, water heater master control borad 115 is the source of trouble.If the alternating voltage of heating rod 111 exceeds level threshold value, heating rod 111 is the source of trouble.
Fault analysis and handling unit 126 is uploaded to multimedia device 127 with detected failure message by information transmission unit 125.Described multimedia device 127 comprises display screen, loudspeaker, according to different faults information, shows and broadcasts alarm sound.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
