Fig. 2 is a schematic structural diagram of another battery chamber submergence detecting system according to an embodiment of the present invention. Referring to fig. 2, on the basis of the above embodiments, optionally, the acquisition module 110 includes: a humidity sensor 111; the humidity sensor 111 is constituted by a humidity sensitive element. There are various ways of selecting the humidity sensor, and accordingly, there are various ways of determining that the humidity of the battery chamber 20 is out of limit, and some of them will be described below, but the present invention is not limited thereto.
In one embodiment, optionally, the humidity sensitive element is a humidity sensitive resistor, and accordingly, the humidity electrical signal comprises: resistance value of the humidity sensitive resistor. The humidity sensitive resistor features that a layer of humidity sensitive material is coated on the substrate, and when water vapor in air is adsorbed onto the humidity sensitive film, the resistivity and resistance of the element are changed and the resistance is inversely related to humidity. That is, when the humidity sensor 111 is formed using a humidity sensitive resistance element, the resistance value decreases as the humidity of the battery chamber 20 increases. Therefore, in this case, the humidity of the battery cell 20 exceeding the limit includes: the resistance value is smaller than the resistance threshold value.
In another embodiment, the humidity sensitive element is a humidity sensitive capacitor, and the humidity electrical signal comprises: capacitance value of the humidity sensitive capacitor. The humidity sensitive capacitor is generally made of a polymer film capacitor, and the commonly used polymer materials include polystyrene, polyimide, acetate butyrate and the like. When the environmental humidity changes, the dielectric constant of the humidity sensitive capacitor changes, so that the capacitance of the humidity sensitive capacitor also changes, and the capacitance change quantity of the humidity sensitive capacitor is in direct proportion to the relative humidity. That is, when the humidity sensor 111 is configured by a humidity-sensitive capacitor element, the capacitance value increases as the humidity of the battery chamber 20 increases. Therefore, in this case, the humidity of the battery cell 20 exceeding the limit includes: the capacitance value is greater than the capacitance threshold value.
With continued reference to fig. 2, in the above embodiments, an ac power source is required to be used as the operating power source of the humidity sensor 111 to prevent the humidity sensor 111 from performance degradation and even failure. The operation module 120 and the execution module 130 usually require direct current, and the power voltages required by the modules may be different. To meet the power demand of each module in the monitoring system, optionally, the power module 140 includes: a junction box 141 and a switching unit 142.

The conversion unit 142 is electrically connected to the operation module 120 and the execution module 130 respectively; the conversion unit 142 is used for converting the alternating current into the direct current and supplying power to the operation module 120 and the execution module 130. Alternatively, the conversion unit may be formed using a logic circuit or a conversion chip.
With continued reference to fig. 2, on the basis of the foregoing embodiments, optionally, the operation module 120 includes: an arithmetic unit 121 and a crystal oscillation unit 122.

Alternatively, the arithmetic unit 121 may include a logic unit such as a comparator for comparing the humidity electrical signal with a signal threshold and outputting the comparison result. The crystal oscillator unit 122 is used for providing a clock signal for the battery chamber immersion detection system so as to ensure the clock synchronization of the whole detection system; the crystal oscillator unit 122 may also be responsible for protecting the epitaxial shape of the arithmetic unit 121.
With continued reference to fig. 2, on the basis of the foregoing embodiments, optionally, the execution module 130 includes: an alarm unit 131 and an execution unit 132.
The alarm unit 131 is used to give an alarm when the humidity of the battery chamber 20 is over. The alarm unit 131 may be provided in various ways. Optionally, the alarm unit 131 includes: a buzzer 1311. When the humidity is beyond the limit, the water immersion degree can be represented by the alarm sound of the buzzer. Or the alarm unit 131 includes: an indicator light 1312. When the humidity is beyond the limit, the flashing state of the indicator light can indicate the degree of water immersion. Or, the alarm unit 131 further includes a display screen, and when the humidity of the battery chamber 20 is out of limit, besides the sound and light alarm, alarm information such as humidity value is displayed on the display screen, which is beneficial for the staff to obtain the state information of the battery chamber 20 in time.
The execution unit 132 is configured to perform the dehumidification process when the humidity of the battery chamber 20 is lower than a predetermined limit. Optionally, the execution unit 132 includes: a relay 1321; the relay 1321 is electrically connected to the dehumidifying device 40, and the relay 1321 is configured to be turned on when the humidity of the battery chamber 20 exceeds a limit, and to control the starting of the dehumidifying device 40.
Alternatively, the dehumidifying device 40 may be a water pump or the like disposed outside the battery chamber. The relay 1321 functions to control the on/off state of the dehumidifying apparatus 40. Taking a water pump as an example, when the environment of the battery chamber 20 is normal, the relay 1321 is kept off, and the water pump does not operate. When the humidity of the storage battery chamber 20 is out of limit, the relay 1321 is conducted, the water pump is started, accumulated water in the storage battery chamber 20 is pumped out until the humidity of the storage battery chamber 20 returns to a normal state, and the fault risk of equipment in the storage battery chamber 20 is reduced.
