Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in figure 1, the water tank water level height indicating and alarming system consists of a water tank, a water level detection circuit module, an alarm signal sampling circuit module, a duty room alarm circuit module and a GSM short message communication alarm circuit module.

As shown in figures 1-2, 1 electrode is connected to the bottom of a water tank and serves as a common electrode at the bottom of the water tank, and other 5 electrodes respectively detect 5 water level states of too low water level, normal water level, too high water level and too high water level. The detection principle is as follows: when the water level is not reached, the water level electrode and the common electrode are disconnected, the resistance is infinite, and the water level detection circuit does not work; when the water level is reached, water resistance exists between the water level electrode and the common electrode, and the water level detection circuit works; according to the working condition of the circuit, the water level state of the water tank can be indicated by using an LED lamp; the alarm signal sampling circuit takes out the information of too high and too low water level to send out 1 low level alarm signal, on one hand, the alarm signal sampling circuit drives the circuit of the duty room to alarm; and on the other hand, the singlechip is driven to be communicated with the GSM short message communication module through the singlechip, so that the GSM short message communication module is realized, and a short message alarm signal is sent to the mobile phone of the person in charge when the water level is too high or too low.

As shown in fig. 3-4, in the water level height indicating alarm system of the water tank, 8050 is a triode which plays a role of amplifying large current, J is an electromagnetic relay of DC6V, and when the power is not supplied, a normally open contact is opened and a normally closed contact is closed; when the power is on, the power supply is normally open and closed, and IN4007 is a protection diode. The working principle is as follows: when the water level is not reached, the water electrode is disconnected, the triode is cut off, and the relay does not work, namely when no water exists, D1 is bright, and D2 is not bright; when the water level is up, the water electrode detects water, the triode is conducted due to water resistance, the relay is in attraction operation, namely when water exists, the D1 is not lighted, the D2 is lighted, and whether the water level reaches a certain state or not is judged according to the lighting and non-lighting conditions of the D1 and the D2. In order to prevent false alarm, the electrodes are put into the water tank and then electrified. When debugging, the electrode for detecting the over-low water level can be connected with the 51K resistor, and the resistor is removed when the water level is put into the water.

As shown in figure 5, the water level height indicating and alarming system of the water tank needs 5 sets of relay systems for detecting 5 water level states, wherein the upper row of LED lamps (connected with normally closed contacts) are not lighted when the water level is low, and the lower row of LED lamps (connected with normally open contacts) are lighted when the water level is high. D1D2 one group reflects too low a condition; D3D4 one group reflects a low case; D5D6 group reflects normal conditions; one group of D7D8 reflects a high-bias condition; the D9D10 group reflects a too high situation. D1, D3, D5, D7 and D9 are all bright, indicating that the water level is too low; d1 is not bright, D3, D5, D7 and D9 are all bright, which indicates that the water level is low; d1 and D3 are not bright, D5, D7 and D9 are all bright, and the water level is normal; d1, D3 and D5 are not bright, and D7 and D9 are both bright, which also indicates that the water level is normal; d1, D3, D5 and D7 are not bright, and D9 is bright, which indicates that the water level is higher; d1, D3, D5, D7 and D9 are all not bright, which indicates that the water level is too high; the lower row of LED lamps is turned on and off oppositely to the upper row, and Vcc is provided with a 12V12.5A adjustable power supply.

As shown in FIG. 6, in a water tank water level height indicating alarm system, when the water level is too high, a water electrode detects water, the water electrode is normally opened and closed, and the output A is 0 level; when the water level is too low, the water electrode of fig. 6 does not detect water, it closes normally, and the output B is at 0 level. U1 is NAND gate 74LS00, U2, U3 are AND gate 74LS08, thus, when the water level is too high or too low, namely when the input AB is 01, 10, the output 1 level duty room alarm signal drives the duty room alarm; outputting P11P10 to the singlechip, wherein P11P10=01, and alarming when the water level is too low; P11P10=10, alarm of too high water level; P11P10=11 no alarm; the P11P10=00 case does not occur.

As shown in figure 7, when the water level is too high or too low, the alarm circuit of the duty room is shown in figure 7, when the alarm signal of the duty room is 1 level, the solid state relay ACSSR works, the alternating current 220V power supply is connected with the electric bell, and the electric bell works and alarms.

As shown in FIG. 8, the water level height indicating alarm system for the water tank comprises a GSM short message communication alarm circuit module, a singlechip and a GSM module. Firstly, programming a minimum application system of the singlechip, programming the telephone number of received information, the short message alarm content, the short message alarm to be automatically sent, the sending times, the time interval and other contents into the singlechip in advance by using C language, realizing the communication work of the singlechip and the GSM short message communication module, and enabling the GSM short message communication module to send alarm information to a mobile phone. When a P11P10 port of the minimum application system of the singlechip receives a 01 or 10 level signal, the GSM module circuit is controlled to automatically send a short message alarm signal to a mobile phone of a user, and a 'please note' is sent when P11P10=01, and the water level of the water tank at the first place is in a too low state at present; P11P10=10, "note that the water level in the first water tank is now too high". When the GSM module is applied, a registered telephone number card of a short message to be sent is inserted. The type of the single chip microcomputer: STC12C5a60S2, GSM module model: SIM 900A.
